(Continued from previous page)
 
   
     The Preferred Securities and the Common Securities will rank pari passu
with each other and will have equivalent terms; provided that (i) if an Event of
Default (as defined herein) under the Declaration (as defined herein) occurs and
is continuing, the holders of Preferred Securities will have a priority over
holders of the Common Securities with respect to distributions (as defined
herein) and payments upon liquidation, redemption or otherwise and (ii) holders
of Common Securities have the exclusive right (subject to the terms of the
Declaration) to appoint, replace or remove Trustees (as defined in the
accompanying Prospectus) and to increase or decrease the number of Trustees. The
payment of distributions out of moneys held by the Property Trustee (as defined
in the accompanying Prospectus) and payments upon liquidation of the Trust and
on redemption of Preferred Securities, as set forth below, are guaranteed by the
Company on a subordinated basis as and to the extent described herein (the
"Preferred Securities Guarantee"). See "Description of the Preferred Securities
Guarantees" in the accompanying Prospectus. The Preferred Securities Guarantee
covers payments of distributions and other payments on the Preferred Securities
only if and to the extent that the Trust has funds available therefor which will
not be the case unless the Company has made a payment of interest or principal
or other payments on the Junior Subordinated Debentures held by the Trust as its
sole asset. The Preferred Securities Guarantee, when taken together with the
Company's obligations under the Junior Subordinated Debentures and the Indenture
(as defined herein) and its obligations under the Declaration, including its
obligation to pay all costs, expenses, debts and other obligations of the Trust
(other than with respect to the Trust Securities), provides a full and
unconditional guarantee of amounts due on the Preferred Securities. The
obligations of the Company under the Preferred Securities Guarantee are
subordinate and junior in right of payment to all other indebtedness,
liabilities and obligations of the Company and any guarantees, endorsements or
other contingent obligations of the Company in respect of such indebtedness,
liabilities or obligations, including Junior Subordinated Debt Securities (as
defined in the accompanying Prospectus) and senior to all capital stock now or
hereafter issued by the Company and to any guarantee now or hereafter entered
into by the Company in respect of its capital stock. The obligations of the
Company under the Junior Subordinated Debentures are subordinate and junior in
right of payment to all present and future Senior Indebtedness (as defined in
the accompanying Prospectus). Because the Company is a holding company, the
Junior Subordinated Debentures (and the Company's obligations under the
Preferred Securities Guarantee) are also effectively subordinated to all
existing and future liabilities, including trade payables, of the Company's
subsidiaries, except to the extent that the Company is a creditor of the
subsidiaries recognized as such.
    
 
   
     Holders of the Preferred Securities will be entitled to receive cumulative
cash distributions at an annual rate of     % of the stated liquidation amount
of $25 per Preferred Security, accruing from the date of original issuance of
the Preferred Securities and payable monthly, in arrears, on the first day of
each month, commencing on             , 1996 ("distributions"). Cash
distributions in arrears for more than one month will bear interest thereon at
the annual rate of     % of the stated liquidation amount of $25 per Preferred
Security (to the extent permitted by applicable law), compounded monthly. The
term "distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated. The distribution rate and the
distribution and other payment dates for the Preferred Securities will
correspond to the interest rate and the interest and other payment dates on the
Junior Subordinated Debentures deposited in the Trust as trust assets. If
principal or interest is not paid on the Junior Subordinated Debentures,
including as a result of the Company's election to extend the interest payment
period on the Junior Subordinated Debentures as described below, the Trust will
not make payments on the Trust Securities. The Junior Subordinated Debentures
provide that, so long as the Company shall not be in default in the payment of
interest on the Junior Subordinated Debentures, the Company shall have the right
to defer payments of interest on the Junior Subordinated Debentures by extending
the interest payment period from time to time for a period not exceeding 60
consecutive monthly interest periods (each, an "Extension Period"). No interest
shall be due and payable during an Extension Period and, as a consequence,
distributions on the Trust Securities will also be deferred, but at the end of
such Extension Period the Company shall pay all interest then accrued and unpaid
on the Junior Subordinated Debentures, together with interest thereon at the
rate specified for the Junior Subordinated Debentures to the extent permitted by
applicable law, compounded monthly ("Compounded Interest"). All references
herein to interest shall include Compounded Interest unless otherwise stated.
There could be multiple Extension Periods of varying lengths throughout the term
of the Junior Subordinated Debentures, each not to exceed 60 consecutive monthly
interest periods or to cause any extension beyond the maturity of the Junior
Subordinated Debentures. During any Extension Period, the Company may not
declare or pay dividends on, or redeem, purchase, acquire or make a distribution
or liquidation payment with respect to, any of its common stock or preferred
stock or make any payments on guarantees with respect thereto;
    
 
                                       S-2

provided, however, that the foregoing restrictions shall not apply to (i)
dividends, redemptions, purchases, acquisitions, distributions or payments made
by the Company by way of issuance of shares of its capital stock, (ii) payments
of accrued dividends by the Company upon the redemption, exchange or conversion
of any preferred stock of the Company as may be outstanding from time to time in
accordance with the terms of such preferred stock or (iii) cash payments made by
the Company in lieu of delivering fractional shares upon the redemption,
exchange or conversion of any preferred stock of the Company as may be
outstanding from time to time in accordance with the terms of such preferred
stock. See "Risk Factors -- Option to Extend Interest Payment Period; Tax Impact
of Extension;" "Description of the Junior Subordinated Debentures -- Interest"
and "-- Option to Extend Interest Payment Period."
 
   
     The Junior Subordinated Debentures are redeemable by the Company (in whole
or in part) from time to time on or after           , 2001, or at any time in
certain circumstances upon the occurrence of a Tax Event (as defined herein). If
the Company redeems Junior Subordinated Debentures, the Trust must redeem Trust
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Junior Subordinated Debentures so redeemed at $25 per
Trust Security plus accrued and unpaid distributions thereon (the "Redemption
Price") to the date fixed for redemption. See "Description of the Preferred
Securities -- Mandatory Redemption." The Preferred Securities will be redeemed
upon maturity of the Junior Subordinated Debentures. The Junior Subordinated
Debentures mature on             , 2036. In addition, upon the occurrence of a
Special Event (as defined herein) arising from a change in law or a change in
legal interpretation, unless the Junior Subordinated Debentures are redeemed in
the limited circumstances described below, the Trust shall be dissolved with the
result that the Junior Subordinated Debentures will be distributed to the
holders of the Preferred Securities, on a pro rata basis, in lieu of any cash
distribution. In the case of a Special Event that is a Tax Event, the Company
will have the right in certain circumstances to redeem the Junior Subordinated
Debentures, which would result in the redemption by the Trust of the Trust
Securities in the same amount on a pro rata basis. If the Junior Subordinated
Debentures are distributed to the holders of the Preferred Securities, the
Company will use its best efforts to have the Junior Subordinated Debentures
listed on the NYSE or on such other exchange as the Preferred Securities are
then listed. See "Description of the Preferred Securities -- Special Event
Redemption or Distribution" and "Description of the Junior Subordinated
Debentures."
    
 
     In the event of the voluntary or involuntary liquidation, dissolution,
winding up or termination of the Trust, the holders of the Preferred Securities
will be entitled to receive, for each Preferred Security, a liquidation amount
of $25 plus accrued and unpaid distributions thereon (including interest
thereon) to the date of payment, unless in connection with such dissolution, the
Junior Subordinated Debentures are distributed to the holders of the Preferred
Securities. See "Description of the Preferred Securities--Liquidation
Distribution Upon Dissolution."

                                  RISK FACTORS
 
     Prospective purchasers of Preferred Securities should carefully review the
information contained elsewhere in this Prospectus Supplement and in the
accompanying Prospectus and should particularly consider the following matters:
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER PREFERRED SECURITIES GUARANTEE AND
JUNIOR SUBORDINATED DEBENTURES; DEPENDENCE ON THE COMPANY
 
   
     The obligations of the Company under the Junior Subordinated Debentures are
unsecured obligations of the Company and will be subordinate and junior in right
of payment to Senior Indebtedness of the Company (as herein defined and which
generally consists of any indebtedness, liabilities or obligations of the
Company, contingent or otherwise, other than the Preferred Securities Guarantee)
but senior to its capital stock. The Company's obligations under the Preferred
Securities Guarantee are unsecured and will rank (i) subordinate and junior in
right of payment to all other indebtedness, liabilities and obligations of the
Company and any guarantees, endorsements or other contingent obligations of the
Company in respect of such indebtedness, liabilities or obligations, including
the Junior Subordinated Debentures and any other series of Junior Subordinated
Debt Securities, except those made pari passu or subordinate by their terms, and
(ii) senior to all capital stock now or hereafter issued by the Company and to
any guarantee now or hereafter entered into by the Company in respect of its
capital stock. Because the Company is a holding company, the Junior Subordinated
Debentures (and the Company's obligations under the Preferred Securities
Guarantee) are also effectively subordinated to all existing and future
liabilities, including trade payables, of the Company's subsidiaries, except to
the extent that the Company is a creditor of the subsidiaries recognized as
such. There are no terms in the Preferred Securities, the Junior Subordinated
Debentures or the Preferred Securities Guarantee that limit the Company's
ability to incur additional indebtedness, including indebtedness that ranks
senior to or pari passu with the Junior Subordinated Debentures and the
Preferred Securities Guarantee, or the ability of its subsidiaries to incur
additional indebtedness. See "Description of the Preferred Securities
Guarantees -- Status of the Preferred Securities Guarantees" and "Description of
the Junior Subordinated Debt Securities -- Subordination" in the accompanying
Prospectus.
    
 
   
     The Trust's ability to make distributions and other payments on the
Preferred Securities is solely dependent upon the Company making interest and
other payments on the Junior Subordinated Debentures deposited as trust assets
as and when required. If the Company were not to make distributions or other
payments on the Junior Subordinated Debentures for any reason, including as a
result of the Company's election to defer the payment of interest on the Junior
Subordinated Debentures by extending the interest period on the Junior
Subordinated Debentures, the Trust will not make payments on the Trust
Securities. In such an event, holders of the Preferred Securities would not be
able to rely on the Preferred Securities Guarantee since distributions and other
payments on the Preferred Securities are subject to the Preferred Securities
Guarantee only if and to the extent that the Company has made a payment to the
Property Trustee of interest or principal on the Junior Subordinated Debentures
deposited in the Trust as trust assets. Instead, holders of Preferred Securities
would rely on the enforcement (i) by the Property Trustee of its rights as
registered holder of the Junior Subordinated Debentures against the Company
pursuant to the terms of the Indenture or (ii) by such holder of Preferred
Securities of its right against the Company to directly enforce payments of
principal and interest on the Junior Subordinated Debentures. However, if the
Trust's failure to make distributions on the Preferred Securities is a
consequence of the Company's exercise of its right to extend the interest
payment period for the Junior Subordinated Debentures, neither the Property
Trustee nor any holder of Preferred Securities will have any right to enforce
the payment of distributions on the Preferred Securities until an Event of
Default under the Declaration shall have occurred. The Company's obligations
under the Preferred Securities Guarantee are subordinate and junior in right of
payment to all other indebtedness, liabilities and obligations of the Company
and any guarantees, endorsements or other contingent obligations of the Company
in respect of such indebtedness, liabilities or obligations, including the
Junior Subordinated Debentures, and any other series of Junior Subordinated Debt
Securities, except those made pari passu or subordinate by their terms to the
Preferred Securities Guarantee, and senior to its capital stock or to any
guarantee of the Company in respect of its capital stock. The Declaration
provides that each holder
    
 
                                       S-4
<PAGE>   8
 
   
of Preferred Securities, by acceptance thereof, agrees to the provisions of the
Preferred Securities Guarantee, including the subordination provisions thereof,
and of the Indenture.
    
 
     The Declaration provides that the Company shall pay for all debts and
obligations (other than with respect to the Trust Securities) and all costs and
expenses of the Trust, including any taxes and all costs and expenses with
respect thereto, to which the Trust may become subject, except for United States
withholding taxes. No assurance can be given that the Company will have
sufficient resources to enable it to pay such debts, obligations, costs and
expenses on behalf of the Trust.
 
   
     If an Event of Default (as defined herein) occurs and is continuing, then
the holders of Preferred Securities would rely on the enforcement by the
Property Trustee of its rights as a holder of the Junior Subordinated Debentures
against the Company. In addition, the holders of a majority in liquidation
amount of the Preferred Securities will have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee or to direct the exercise of any trust or power conferred upon
the Property Trustee under the Declaration, including the right to direct the
Property Trustee to exercise the remedies available to it as a holder of the
Junior Subordinated Debentures. If the Property Trustee fails to enforce its
rights under the Junior Subordinated Debentures, any holder of Preferred
Securities may, to the extent permitted by applicable law, after a period of 30
days has elapsed from such holder's written request, directly institute a legal
proceeding against the Company to enforce the Property Trustee's rights under
the Junior Subordinated Debentures without first instituting any legal
proceeding against the Property Trustee or any other person or entity. If an
Event of Default occurs and is continuing and such event is attributable to the
failure of the Company to pay interest or principal on the Junior Subordinated
Debentures on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities may also directly institute a proceeding for enforcement of payment
to such holder of the principal of or interest on Junior Subordinated Debentures
having a principal amount equal to the aggregate liquidation amount of the
Preferred Securities held by such holder (a "Direct Action") on or after the
respective due date specified in the Junior Subordinated Debentures without
first (i) directing the Property Trustee to enforce the terms of the Junior
Subordinated Debentures or (ii) instituting a legal proceeding against the
Company to enforce the Property Trustee's rights under the Junior Subordinated
Debentures. In connection with such Direct Action, the Company will be
subrogated to the rights of such holder of Preferred Securities under the
Declaration to the extent of any payment made by the Company to such holder of
Preferred Securities in such Direct Action. The holders of Preferred Securities
will not be able to exercise directly any other remedy available to the holders
of the Junior Subordinated Debentures unless the Property Trustee first fails to
do so.
    
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX IMPACT OF EXTENSION
 
   
     So long as the Company shall not be in default in the payment of interest
on the Junior Subordinated Debentures, the Company has the right under the
Indenture to defer payments of interest on the Junior Subordinated Debentures by
extending the interest payment period from time to time on the Junior
Subordinated Debentures for an Extension Period not exceeding 60 consecutive
monthly interest periods, during which no interest shall be due and payable. In
such an event, monthly distributions on the Preferred Securities would not be
made (but would continue to accrue with interest thereon at the rate of     %
per annum, compounded monthly) by the Trust during any such Extension Period. If
the Company exercises the right to extend an interest payment period, the
Company may not during such Extension Period declare or pay dividends on, or
redeem, purchase, acquire or make a distribution or liquidation payment with
respect to, any of its common stock or preferred stock or make any payments on
guarantees with respect thereto; provided, however, that the foregoing
restrictions shall not apply to (i) dividends, redemptions, purchases,
acquisitions, distributions or payments made by the Company by way of issuance
of shares of its capital stock, (ii) payments of accrued dividends by the
Company upon the redemption, exchange or conversion of any preferred stock of
the Company as may be outstanding from time to time in accordance with the terms
of such preferred stock or (iii) cash payments made by the Company in lieu of
delivering fractional shares upon the redemption, exchange or conversion of any
preferred stock of the Company as may be outstanding from time to time in
accordance with the terms of such preferred stock. See "Description of the
Junior Subordinated
    
 
                                       S-5
<PAGE>   9
 
Debentures -- Option to Extend Interest Payment Period" for a description of
certain terms of the outstanding preferred stock of the Company.
 
   
     Prior to the termination of any Extension Period, the Company may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 60 consecutive
monthly interest periods. Upon the termination of any Extension Period and the
payment of all amounts then due, the Company may commence a new Extension
Period, subject to the above requirements. The Company may also prepay at any
time all or any portion of the interest accrued during an Extension Period.
Consequently, there could be multiple Extension Periods of varying lengths
throughout the term of the Junior Subordinated Debentures, each not to exceed 60
consecutive monthly interest periods or to cause any extension beyond the
maturity of the Junior Subordinated Debentures. See "Description of the
Preferred Securities -- Distributions" and "Description of the Junior
Subordinated Debentures -- Option to Extend Interest Payment Period."
    
 
   
     If an Extension Period occurs, the Junior Subordinated Debentures would be
considered to have original issue discount for U.S. Federal income tax purposes
at all times after the beginning of the first Extension Period, including after
the termination of the Extension Period. During such times, each holder, whether
on the cash or accrual method of accounting, will be required to include its pro
rata share of original issue discount into income as it accrues, even though no
cash will be distributed during an Extension Period. Even before the beginning
of the first Extension Period, while the Company will take the position that
original issue discount does not arise, it is possible that all income on the
Junior Subordinated Debentures would be accounted for as original issue
discount, and stated interest would not separately be reported as taxable
income. The Company has no current intention of exercising its option to defer
payments of interest. See "Taxation -- Interest and Original Issue Discount."
    
 
SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
   
     Upon the occurrence and during the continuation of a Tax Event or
Investment Company Event (each as defined herein), which may occur at any time,
the Trust shall, unless the Junior Subordinated Debentures are redeemed in the
limited circumstances described below, be dissolved with the result that, in the
manner described in "Description of the Preferred Securities -- Liquidation
Distribution Upon Dissolution," Junior Subordinated Debentures having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid distributions on, the Preferred Securities and the Common Securities
would be distributed on a Pro Rata Basis (as defined under the caption "PWG
Trusts" in the accompanying Prospectus) to the holders of the Preferred
Securities and the Common Securities in liquidation of the Trust. In the case of
a Tax Event, in certain circumstances, the Company shall have the right to
redeem at any time the Junior Subordinated Debentures, in whole or in part, in
which event the Trust will redeem Preferred Securities and Common Securities on
a Pro Rata Basis to the same extent as the Junior Subordinated Debentures are
redeemed. There can be no assurance as to the market prices for Preferred
Securities or the Junior Subordinated Debentures which may be distributed in
exchange for Preferred Securities if a dissolution and liquidation of the Trust
were to occur. Accordingly, the Preferred Securities that an investor may
purchase, or the Junior Subordinated Debentures that the investor may receive on
dissolution and liquidation of the Trust, may trade at a discount to the price
that the investor paid to purchase the Preferred Securities offered hereby.
Because holders of Preferred Securities may receive Junior Subordinated
Debentures upon the occurrence of a Special Event, prospective purchasers of
Preferred Securities are also making an investment decision with regard to the
Junior Subordinated Debentures and should carefully review all the information
regarding the Junior Subordinated Debentures contained herein and in the
accompanying Prospectus. See "Description of the Preferred Securities -- Special
Event Redemption or Distribution" and "Description of the Junior Subordinated
Debentures -- General."
    
 
   
     Recent legislative proposals by the Clinton Administration would prevent
the Company from deducting interest on the Junior Subordinated Debentures. The
proposals would have applied to instruments issued on or after December 7, 1995.
However, the Chairmen of the Senate Finance and House Ways and Means Committees
have issued a joint statement stating their intention that the proposals, if
enacted, would not apply
    
 
                                       S-6
<PAGE>   10
 
   
to instruments issued prior to the date of appropriate Congressional action. No
such Congressional action has yet occurred. Nevertheless, there can be no
assurance that future legislation would not prevent the Company from deducting
interest on the Junior Subordinated Debentures. Such legislation would
constitute a Tax Event and could result in the distribution of the Junior
Subordinated Debentures to holders of the Preferred Securities or, in certain
circumstances, the redemption of the Junior Subordinated Debentures by the
Company and the distribution of the resulting cash in redemption of the
Preferred Securities. See "Description of the Preferred Securities -- Special
Event Redemption or Distribution" and "Taxation -- Possible Tax Law Changes."
    
 
     Under current United States Federal income tax law, a distribution of the
Junior Subordinated Debentures upon a Tax Event or Investment Company Event
would not be a taxable event to holders of the Preferred Securities. See
"Taxation -- Distribution of Junior Subordinated Debentures to Holders of
Preferred Securities."
 
LIMITING VOTING RIGHTS
 
     Holders of Preferred Securities will have limited voting rights, but will
not be able to appoint, remove or replace, or to increase or decrease the number
of, Trustees, which rights are vested exclusively in the Common Securities.
 
LISTING OF PREFERRED SECURITIES; TRADING PRICES
 
   
     The Preferred Securities constitute a new issue of securities with no
established trading market. The Preferred Securities have been approved for
listing on the NYSE, subject to official notice of issuance. However, there can
be no assurance that an active market for the Preferred Securities will develop
or be sustained in the future on the NYSE. Although PaineWebber has indicated to
the Company and the Trust that it intends to make a market in the Preferred
Securities as permitted by applicable laws and regulations, it is not obligated
to do so and may discontinue any such market-making at any time without notice.
Accordingly, no assurance can be given as to the liquidity of, or trading
markets for, the Preferred Securities.
    
 
   
     The Preferred Securities may trade at a price that does not fully reflect
the value of accrued but unpaid interest with respect to the underlying Junior
Subordinated Debentures. A holder who disposes of his Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest on the Junior Subordinated Debentures
through the date of disposition in income as ordinary income, and to add such
amount to his adjusted tax basis in his pro rata share of the underlying Junior
Subordinated Debentures deemed disposed of. Accordingly, such a holder will
recognize a capital loss to the extent the selling price (which may not fully
reflect the value of accrued but unpaid interest) is less than the holder's
adjusted tax basis (which will include accrued but unpaid interest). Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States Federal income tax purposes. See "Taxation -- Interest
and Original Issue Discount" and "-- Disposition of the Preferred Securities."
    
 
POTENTIAL MARKET VOLATILITY DURING EXTENSION PERIOD
 
   
     As described above, the Company has the right to extend an interest payment
period on the Junior Subordinated Debentures from time to time for a period not
exceeding 60 consecutive monthly interest periods. If the Company determines to
extend an interest payment period, or if the Company thereafter extends an
Extension Period or prepays interest accrued during an Extension Period as
described above, the market price of the Preferred Securities is likely to be
affected. In addition, as a result of such rights, the market price of the
Preferred Securities (which represent an undivided interest in Junior
Subordinated Debentures) may be more volatile than other securities that do not
have such rights. A holder that disposes of its Preferred Securities during an
Extension Period, therefore, may not receive the same return on its investment
as a holder that continues to hold its Preferred Securities. See "Description of
the Junior Subordinated Debentures -- Option to Extend Interest Payment Period."

                                  THE COMPANY
 
   
     Paine Webber Group Inc. is a holding company which, together with its

                              PWG CAPITAL TRUST I
 
   
     PWG Capital Trust I is a business trust formed on October 7, 1996, under
the Delaware Business Trust Act (the "Business Trust Act") pursuant to a
declaration of trust among the Trustees and the Company and the filing of a
certificate of trust with the Secretary of State of the State of Delaware. Such
declaration will be amended and restated in its entirety (as so amended and
restated, the "Declaration") substantially in the form filed as an exhibit to
the Registration Statement of which this Prospectus Supplement and the
accompanying Prospectus form a part, as of the date the Preferred Securities are
initially issued. The Declaration is qualified under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"). Upon issuance of the Preferred
Securities, the holders thereof will own all the issued and outstanding
Preferred Securities. The Company will acquire Common Securities in an amount
equal to at least 3% of the total capital of the Trust and will own, directly or
indirectly, all the issued and outstanding Common Securities. The Trust exists
for the purpose of (a) issuing its Trust Securities for cash and investing the
gross proceeds thereof in an equivalent amount of Junior Subordinated Debentures
and (b) engaging in such other activities as are necessary, convenient or
incidental thereto. The rights of the holders of the Trust Securities, including
economic rights, rights to information and voting rights, are as set forth in
the Declaration, the Business Trust Act and the Trust Indenture Act. The
Declaration does not permit the incurrence by the Trust of any indebtedness for
borrowed money or the making of any investment other than in the Junior
Subordinated Debentures. In the Declaration, the Company has agreed to pay for
all debts and obligations (other than with respect to the Trust Securities) and
all costs and expenses of the Trust, including the fees and expenses of the
Trustees and any taxes and all costs and expenses with respect thereto, to which
the Trust may become subject, except for United States withholding taxes.

Company's financial statements, with the Preferred Securities shown as
Company-obligated mandatorily redeemable preferred securities of subsidiary

                                USE OF PROCEEDS
 
     The proceeds of the sale of the Preferred Securities will be invested by
the Trust in Junior Subordinated Debentures of the Company. The proceeds from
the issuance of such Junior Subordinated Debentures will be used by the Company
for general corporate purposes.
 
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
   
     The Preferred Securities will be issued pursuant to the terms of the
Declaration which is qualified under the Trust Indenture Act. The Property
Trustee, The Chase Manhattan Bank, but not the other Trustees of the Trust, will
act as the indenture trustee for purposes of the Trust Indenture Act. The terms
of the Preferred Securities and the Declaration include those stated in the
Declaration and those made part of the Declaration by the Trust Indenture Act
and the Business Trust Act. The following summarizes the material terms and
provisions of the Preferred Securities and is qualified in its entirety by
reference to the Declaration, which has been filed as an exhibit to the
Registration Statement of which this Prospectus Supplement forms a part, the
Business Trust Act and the Trust Indenture Act.
    
 
GENERAL
 
     The Declaration authorizes the Trust to issue the Preferred Securities,
which represent preferred undivided beneficial interests in the assets of the
Trust, and the Common Securities, which represent common undivided beneficial
interests in the assets of the Trust. All the Common Securities will be owned,
directly or indirectly, by the Company. The Common Securities and the Preferred
Securities rank pari passu with each other and will have equivalent terms except
that (i) if an Event of Default under the Declaration occurs and is continuing,
the holders of Preferred Securities will have a priority over holders of the
Common Securities with respect to distributions and payments upon liquidation,
redemption or otherwise and (ii) holders of Common Securities have the exclusive
right (subject to the terms of the Declaration) to appoint, remove or replace
Trustees and to increase or decrease the number of Trustees. The Declaration
does not permit the issuance by the Trust of any securities or other evidences
of beneficial ownership of, or beneficial interests in, the Trust other than the
Preferred Securities and the Common Securities, the incurrence of any
indebtedness for borrowed money by the Trust or the making of any investment
other than in the Junior Subordinated Debentures. Pursuant to the Declaration,
the Property Trustee will have legal title to, and will hold, the Junior
Subordinated Debentures as trust assets for the benefit of the holders of the
Preferred Securities and the Common Securities. The payment of distributions out
of moneys held by the Property Trustee and payments on redemption of the
Preferred Securities or liquidation of the Trust are guaranteed by the Company
on a subordinated basis as and to the extent described under "Description of the
Preferred Securities Guarantees" in the accompanying Prospectus. The Property
Trustee will hold the Preferred Securities Guarantee for the benefit of holders
of the Preferred Securities. The Preferred Securities Guarantee is a full and
unconditional guarantee from the time of issuance of the Preferred Securities,
but the Preferred Securities Guarantee covers distributions and other payments
on the Preferred Securities only if and to the extent that the Company has made
a payment to the Property Trustee of interest or principal on the Junior
Subordinated Debentures deposited in the Trust as trust assets. See "Voting
Rights."
 
DISTRIBUTIONS
 
     Distributions on the Preferred Securities will be fixed at a rate per annum
of      % of the stated liquidation amount of $25 per Preferred Security.
Distributions in arrears for more than one month will bear interest thereon at
the rate per annum of      % of the stated liquidation amount of $25 per
Preferred Security
 
                                      S-12
<PAGE>   16
 
   
(to the extent permitted by law), compounded monthly. The term "distributions"
as used herein includes any such interest payable unless otherwise stated. The
amount of distributions payable for any period will be computed for any monthly
distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a 30-day period on the basis of the actual number of
days elapsed.
    
 
   
     Distributions on the Preferred Securities will be cumulative, will accrue
from the original date of issuance and, except as otherwise described below,
will be payable monthly in arrears on the first day of each month, commencing on
          , 1996, but only if, and to the extent that, interest payments are
made in respect of Junior Subordinated Debentures held by the Property Trustee.
    
 
   
     So long as the Company shall not be in default in the payment of interest
on the Junior Subordinated Debentures, the Company has the right under the
Indenture to defer payments of interest on the Junior Subordinated Debentures by
extending the interest payment period from time to time on the Junior
Subordinated Debentures for a period not exceeding 60 consecutive monthly
interest periods and, as a consequence, the Trust would defer monthly
distributions on the Preferred Securities (though such distributions would
continue to accrue with interest thereon at the rate of      % per annum,
compounded monthly) during any such Extension Period. If the Company exercises
the right to extend an interest payment period, the Company may not declare or
pay dividends on, or redeem, purchase, acquire or make a distribution or
liquidation payment with respect to, any of its common stock or preferred stock
during such Extension Period or make any guarantee payments with respect
thereto; provided, however, that the foregoing restrictions shall not apply to
(i) dividends, redemptions, purchases, acquisitions, distributions or payments
made by the Company by way of issuance of shares of its capital stock, (ii)
payments of accrued dividends by the Company upon the redemption, exchange or
conversion of any preferred stock of the Company as may be outstanding from time
to time in accordance with the terms of such preferred stock or (iii) cash
payments made by the Company in lieu of delivering fractional shares upon the
redemption, exchange or conversion of any preferred stock of the Company as may
be outstanding from time to time in accordance with the terms of such preferred
stock. Prior to the termination of any such Extension Period, the Company may
further extend such Extension Period; provided that such Extension Period
together with all such previous and further extensions thereof may not exceed 60
consecutive monthly interest periods and may not extend beyond the maturity of
the Junior Subordinated Debentures. Upon the termination of any Extension Period
and the payment of all amounts then due, the Company may commence a new
Extension Period, subject to the above requirements. The Company may also prepay
at any time all or any portion of the interest accrued during an Extension
Period. Consequently, there could be multiple Extension Periods of varying
lengths throughout the term of the Junior Subordinated Debentures, each not to
exceed 60 consecutive monthly interest periods or to cause any extension beyond
the maturity of the Junior Subordinated Debentures. See "Risk Factors -- Option
to Extend Interest Payment Period; Tax Impact of Extension;" "Description of the
Junior Subordinated Debentures -- Interest" and "-- Option to Extend Interest
Payment Period." Subject to prepayments as described above, payments of accrued
distributions will be payable to holders of Preferred Securities as they appear
on the books and records of the Trust on the first record date after the end of
an Extension Period.
    
 
   
     Distributions on the Preferred Securities must be paid on the dates payable
to the extent that the Property Trustee has cash on hand in the Property Account
to permit such payment. The funds available for distribution to the holders of
the Preferred Securities will be limited to payments received by the Property
Trustee in respect of the Junior Subordinated Debentures that are deposited in
the Trust as trust assets. See "Description of the Junior Subordinated
Debentures." If the Company does not make interest payments on the Junior
Subordinated Debentures, the Property Trustee will not make distributions on the
Preferred Securities. Under the Declaration, if and to the extent the Company
does make interest payments on the Junior Subordinated Debentures deposited in
the Trust as trust assets, the Property Trustee is obligated to make
distributions on the Trust Securities on a pro rata basis. The payment of
distributions on the Preferred Securities is guaranteed by the Company on a
subordinated basis as and to the extent set forth under "Description of the
Preferred Securities Guarantees" in the accompanying Prospectus. The Preferred
Securities Guarantee is a full and unconditional guarantee from the time of
issuance of the Preferred Securities, but the Preferred Securities Guarantee
covers distributions and other payments on the Preferred
    
 
                                      S-13
<PAGE>   17
 
Securities only if and to the extent that the Company has made a payment to the
Property Trustee of interest or principal on the Junior Subordinated Debentures
deposited in the Trust as trust assets.
 
   
     Distributions on the Preferred Securities will be made to the holders
thereof as they appear on the books and records of the Trust on the relevant
record dates, which, as long as the Preferred Securities remain in book-entry
only form, will be one Business Day (as defined herein) prior to the relevant
distribution payment date. Distributions payable on any Preferred Securities
that are not punctually paid on any distribution payment date as a result of the
Company having failed to make the corresponding interest payment on the Junior
Subordinated Debentures will forthwith cease to be payable to the person in
whose name such Preferred Security is registered on the relevant record date,
and such defaulted distribution will instead be payable to the person in whose
name such Preferred Security is registered on the special record date
established by the Regular Trustees, which record date shall correspond to the
special record date or other specified date determined in accordance with the
Indenture; provided, however, that distributions shall not be considered payable
on any distribution payment date falling within an Extension Period unless the
Company has elected to make a full or partial payment of interest accrued on the
Junior Subordinated Debentures on such distribution payment date. Distributions
on the Preferred Securities will be paid through the Property Trustee who will
hold amounts received in respect of the Junior Subordinated Debentures in the
Property Account for the benefit of the holders of the Preferred Securities and
the Common Securities. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment will be made as described under
"Book-Entry Only Issuance -- The Depository Trust Company" below. In the event
that the Preferred Securities do not continue to remain in book-entry only form,
the relevant record date will be the fifteenth day of the month immediately
preceding the month in which the relevant payment date occurs. The Declaration
provides that the payment dates or record dates for the Preferred Securities
shall be the same as the payment dates and record dates for the Junior
Subordinated Debentures. All distributions paid with respect to the Trust
Securities shall be paid on a pro rata basis to the holders thereof entitled
thereto. If any date on which distributions are to be made on the Preferred
Securities is not a Business Day, then payment of the distribution to be made on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day is in the next succeeding calendar year, such payment shall
be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on such date. "Business Day" shall mean any day
other than Saturday, Sunday or any other day on which banking institutions in
the City of New York in the State of New York are authorized or required by law
to close.
    
 
SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
   
     If, at any time, a Tax Event or an Investment Company Event (each as
hereinafter defined, and each a "Special Event") shall occur and be continuing,
the Trust shall, unless the Junior Subordinated Debentures are redeemed in the
limited circumstances described below, be dissolved with the result that, after
satisfaction of creditors of the Trust, Junior Subordinated Debentures with an
aggregate principal amount equal to the aggregate stated liquidation amount of
the Preferred Securities and the Common Securities would be distributed on a pro
rata basis to the holders of the Preferred Securities and the Common Securities
in liquidation of such holders' interests in the Trust, within 90 days following
the occurrence of such Special Event; provided, however, that in the case of the
occurrence of a Tax Event, as a condition of such dissolution and distribution,
the Regular Trustees (as defined in the accompanying Prospectus) shall have
received an opinion of nationally recognized independent tax counsel experienced
in such matters (a "No Recognition Opinion"), which opinion may rely on any then
applicable published revenue rulings of the Internal Revenue Service, to the
effect that the holders of the Preferred Securities will not recognize any gain
or loss for United States Federal income tax purposes as a result of such
dissolution and distribution of Junior Subordinated Debentures; and, provided
further, that, if at the time there is available to the Trust the opportunity to
eliminate, within such 90-day period, the Special Event by taking some
ministerial action, such as filing a form or making an election, or pursuing
some other similar reasonable measure, which has no adverse effect on the Trust
or the Company or the holders of the Preferred Securities, the Trust will pursue
such measure in lieu of dissolution. Furthermore, if in the case of the
occurrence of a Tax Event, (i) the Regular Trustees have received an opinion (a
"Redemption Tax Opinion") of nationally recognized independent tax counsel
    
 
                                      S-14
<PAGE>   18
 
   
experienced in such matters that, as a result of such Tax Event, there is more
than an insubstantial risk that the Company would be precluded from deducting
the interest on the Junior Subordinated Debentures for United States Federal
income tax purposes even if the Junior Subordinated Debentures were distributed
to the holders of Trust Securities in liquidation of such holders' interests in
the Trust as described above or (ii) the Regular Trustees shall have been
informed by such tax counsel that a No Recognition Opinion cannot be delivered
to the Trust, the Company shall have the right at any time, upon not less than
30 nor more than 60 days notice, to redeem the Junior Subordinated Debentures in
whole or in part for cash within 90 days following the occurrence of such Tax
Event, and promptly following such redemption Preferred Securities and Common
Securities with an aggregate liquidation amount equal to the aggregate principal
amount of the Junior Subordinated Debentures so redeemed will be redeemed by the
Trust at the Redemption Price on a pro rata basis; provided, however, that if at
the time there is available to the Company or the Regular Trustees, on behalf of
the Trust, the opportunity to eliminate, within such 90-day period, such Tax
Event by taking some ministerial action, such as filing a form or making an
election, or pursuing some other similar reasonable measure, which has no
adverse effect on the Trust, the Company or the holders of the Preferred
Securities, the Company or the Regular Trustees, on behalf of the Trust, will
pursue such measure in lieu of redemption and provided further that the Company
shall have no right to redeem the Junior Subordinated Debentures while the
Regular Trustees, on behalf of the Trust, are pursuing any such ministerial
action. The Common Securities will be redeemed on a pro rata basis with the
Preferred Securities, except that if an Event of Default under the Declaration
has occurred and is continuing, the Preferred Securities will have a priority
over the Common Securities with respect to payment of the Redemption Price.
    
 
   
     "Tax Event" means that the Regular Trustees shall have obtained an opinion
of nationally recognized independent tax counsel experienced in such matters (a
"Dissolution Tax Opinion") to the effect that on or after the date of this
Prospectus Supplement as a result of (a) any amendment to, or change in, the
laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, (b) any amendment to, or
change (including any announced prospective change) in, an interpretation or
application of any such laws or regulations by any legislative body, court,
governmental agency or regulatory authority (including the enactment of any
legislation and the publication of any judicial decision or regulatory
determination), (c) any interpretation or pronouncement that provides for a
position with respect to such laws or regulations that differs from the
theretofore generally accepted position or (d) any action taken by any
governmental agency or regulatory authority, which amendment or change is
enacted, promulgated, issued or effective or which interpretation or
pronouncement is issued or announced or which action is taken, in each case on
or after the date of this Prospectus Supplement, there is more than an
insubstantial risk that (i) the Trust is, or will be within 90 days of the date
thereof, subject to United States Federal income tax with respect to income
accrued or received on the Junior Subordinated Debentures, (ii) the Trust is, or
will be within 90 days of the date thereof, subject to more than a de minimis
amount of other taxes, duties or other governmental charges or (iii) interest
payable by the Company to the Trust on the Junior Subordinated Debentures is
not, or within 90 days of the date thereof will not be, deductible by the
Company for United States Federal income tax purposes.
    
 
   
     "Investment Company Event" means that the Regular Trustees shall have
received an opinion of nationally recognized independent counsel experienced in
practice under the Investment Company Act of 1940, as amended (the "1940 Act"),
that, as a result of the occurrence of a change in law or regulation or a change
in interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
there is more than an insubstantial risk that the Trust is or will be considered
an "investment company" which is required to be registered under the 1940 Act,
which Change in 1940 Act Law becomes effective on or after the date of this
Prospectus Supplement.
    
 
     On the date fixed for any distribution of Junior Subordinated Debentures,
upon dissolution of the Trust, (i) the Preferred Securities and the Common
Securities will no longer be deemed to be outstanding, (ii) the depositary or
its nominee, as the record holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Junior
Subordinated Debentures to be delivered upon such distribution and (iii) any
certificates representing Preferred Securities not held by the depositary or its
nominee will be deemed to represent Junior Subordinated Debentures having an
aggregate principal amount
 
                                      S-15
<PAGE>   19
 
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the distribution rate of, and accrued and unpaid interest equal to
accrued and unpaid distributions on, such Preferred Securities, until such
certificates are presented to the Company or its agent for transfer or
reissuance.
 
     There can be no assurance as to the market price for the Junior
Subordinated Debentures which may be distributed in exchange for Preferred
Securities if a dissolution and liquidation of the Trust were to occur.
Accordingly, the Junior Subordinated Debentures which a holder of Preferred
Securities may subsequently receive upon the dissolution of the Trust may trade
at a discount to the price of the Preferred Securities exchanged. If the Junior
Subordinated Debentures are distributed to the holders of Preferred Securities
upon the dissolution of the Trust, the Company will use its best efforts to list
the Junior Subordinated Debentures on the NYSE or on such other exchange on
which the Preferred Securities are then listed.
 
MANDATORY REDEMPTION
 
   
     Upon the repayment of the Junior Subordinated Debentures, whether at
maturity, upon redemption or otherwise, the proceeds from such repayment will be
promptly applied to redeem Preferred Securities and Common Securities having an
aggregate liquidation amount equal to the Junior Subordinated Debentures so
repaid, upon not less than 30 nor more than 60 days' notice, at the Redemption
Price. The Common Securities will be entitled to be redeemed on a pro rata basis
with the Preferred Securities, except that if an Event of Default under the
Declaration has occurred and is continuing, the Preferred Securities will have a
priority over the Common Securities with respect to payment of the Redemption
Price. Subject to the foregoing, if fewer than all outstanding Preferred
Securities and Common Securities are to be redeemed, the Preferred Securities
and Common Securities will be redeemed on a pro rata basis. In the event fewer
than all outstanding Preferred Securities are to be redeemed, Preferred
Securities registered in the name of and held by DTC or its nominee will be
redeemed as described under "Description of Preferred Securities -- Book-Entry
Only Issuance; The Depository Trust Company" below.
    
 
REDEMPTION PROCEDURES
 
     The Trust may not redeem fewer than all the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Preferred Securities for all monthly distribution periods terminating on or
prior to the date of redemption.
 
   
     If the Trust gives a notice of redemption in respect of Preferred
Securities (which notice will be irrevocable) then, by 12:00 noon, New York City
time, on the redemption date and provided that the Company has paid to the
Property Trustee a sufficient amount of cash in connection with the related
redemption or maturity of the Junior Subordinated Debentures, the Trust will
irrevocably deposit with the Depositary funds sufficient to pay the applicable
Redemption Price and will give the Depositary irrevocable instructions and
authority to pay the Redemption Price to the holders of the Preferred
Securities. See "Book-Entry Only Issuance; The Depository Trust Company." If
notice of redemption shall have been given and funds deposited as required,
then, immediately prior to the close of business on the redemption date,
distributions will cease to accrue on the Preferred Securities called for
redemption, such Preferred Securities shall no longer be deemed to be
outstanding and all rights of holders of such Preferred Securities so called for
redemption will cease, except the right of the holders of such Preferred
Securities to receive the Redemption Price, but without interest on such
Redemption Price. Neither the Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Preferred Securities
which have been so called for redemption. If any date fixed for redemption of
Preferred Securities is not a Business Day, then payment of the Redemption Price
payable on such date will be made on the next succeeding day that 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 each case with the
same force and effect as if made on such date fixed for redemption. If the
Company fails to repay Junior Subordinated Debentures on maturity or on the date
fixed for redemption or if payment of the Redemption Price in respect of
Preferred Securities is improperly withheld or refused and not paid by the
Property Trustee or by the Company pursuant to the Preferred Securities
Guarantee described under "Description of the Preferred Securities Guarantees"
in the accompanying Prospectus, distributions on the
    
 
                                      S-16
<PAGE>   20
 
   
Preferred Securities will continue to accrue from the original redemption date
of the Preferred Securities to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price.
    
 
   
     In the event that fewer than all the outstanding Preferred Securities are
to be redeemed, the Preferred Securities will be redeemed pro rata as described
below under "Book-Entry Only Issuance; The Depository Trust Company."
    
 
     If a partial redemption of the Preferred Securities would result in the
delisting of the Preferred Securities by any national securities exchange or
other organization on which the Preferred Securities are then listed, the
Company pursuant to the Indenture will only redeem Junior Subordinated
Debentures in whole and, as a result, the Trust may only redeem the Preferred
Securities in whole.
 
     Subject to the foregoing and applicable law (including, without limitation,
United States Federal securities laws), the Company or any of its subsidiaries
may at any time and from time to time purchase outstanding Preferred Securities
by tender, in the open market or by private agreement.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
   
     In the event of any voluntary or involuntary dissolution, winding-up or
termination of the Trust, the holders of the Preferred Securities and the Common
Securities at the date of dissolution, winding-up or termination of the Trust
will be entitled to receive on a pro rata basis solely out of the assets of the
Trust, after satisfaction of liabilities of creditors, an amount equal to the
aggregate of the stated liquidation amount of $25 per Trust Security plus
accrued and unpaid distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
dissolution, winding-up or termination, and after satisfaction of liabilities to
creditors, Junior Subordinated Debentures in an aggregate principal amount equal
to the aggregate stated liquidation amount of such Trust Securities and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
distributions on such Trust Securities shall be distributed on a pro rata basis
to the holders of the Preferred Securities and the Common Securities in exchange
therefor.
    
 
   
     If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities and the Common Securities shall be paid,
subject to the following sentence, on a pro rata basis. The holders of the
Common Securities will be entitled to receive distributions upon any such
dissolution on a pro rata basis with the holders of the Preferred Securities,
except that if an Event of Default under the Declaration has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities with respect to payment of the Liquidation Distribution.
    
 
     Pursuant to the Declaration, the Trust shall terminate: (i) on
  , 2036; (ii) when all the Trust Securities shall have been called for
redemption and the amounts necessary for redemption thereof shall have been paid
to the holders of Trust Securities in accordance with the terms of the Trust
Securities; or (iii) when all the Junior Subordinated Debentures shall have been
distributed to the holders of Trust Securities in exchange for all the Trust
Securities in accordance with the terms of the Trust Securities.
 
NO MERGER, CONSOLIDATION OR SALE OF ASSETS OF THE TRUST
 
     The Trust may not merge or consolidate with or into, or be replaced by, or
sell, transfer or lease all or substantially all its properties and assets to,
any corporation or other entity or, except as expressly permitted hereby, sell
or transfer any junior subordinated debentures to any corporation or other
entity.
 
DECLARATION EVENTS OF DEFAULT
 
     An Indenture Event of Default (as defined in the accompanying Prospectus)
will constitute an event of default under the Declaration with respect to the
Trust Securities (an "Event of Default"); provided that pursuant to the
Declaration, the holder of the Common Securities will be deemed to have waived
any such Event of Default with respect to the Common Securities until all Events
of Default with respect to the
 
                                      S-17
<PAGE>   21
 
Preferred Securities have been cured or waived. Until all such Events of Default
with respect to the Preferred Securities have been so cured or waived, the
Property Trustee will be deemed to be acting solely on behalf of the holders of
the Preferred Securities, and only the holders of the Preferred Securities will
have the right to direct the Property Trustee with respect to certain matters
under the Declaration and consequently under the Indenture. In the event that
any Event of Default with respect to the Preferred Securities is waived by the
holders of the Preferred Securities as provided in the Declaration, the holders
of Common Securities pursuant to the Declaration have agreed that such waiver
also constitutes a waiver of such Event of Default with respect to the Common
Securities for all purposes under the Declaration without any further act, vote
or consent of the holders of the Common Securities. See "Voting Rights."
 
   
     Upon the occurrence of an Event of Default, the Property Trustee as the
holder of all the Junior Subordinated Debentures will have the right under the
Indenture to declare the principal of, and interest on, the Junior Subordinated
Debentures to be immediately due and payable. In addition, the Property Trustee
will have the power to exercise all rights, powers and privileges under the
Indenture. If the Property Trustee fails to enforce its rights under the
Indenture, any holder of Preferred Securities may, to the extent permitted by
applicable law, after a period of 30 days has elapsed from such holder's written
request to the Property Trustee to enforce such rights, institute a legal
proceeding against the Company to enforce the Property Trustee's rights.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
interest or principal on the Junior Subordinated Debentures on the date such
interest or principal is otherwise payable (or in the case of redemption, the
redemption date), then a holder of Preferred Securities may directly institute
suit against the Company for enforcement of payment to such holder of the
principal of or interest on Junior Subordinated Debentures having a principal
amount equal to the aggregate liquidation amount of the Preferred Securities
held by such holder on or after the respective due date specified in the Junior
Subordinated Debentures. The holders of Preferred Securities will not be able to
exercise directly against the Company any other remedy available to the holders
of the Junior Subordinated Debentures unless the Property Trustee first fails to
do so. See "Description of the Junior Subordinated Debentures."
    
 
VOTING RIGHTS
 
     Except as provided below, under "Modification and Amendment of the
Declaration" and "Description of the Preferred Securities
Guarantees -- Amendments and Assignment" in the accompanying Prospectus and as
otherwise required by the Business Trust Act, the Trust Indenture Act or the
Declaration, the holders of the Preferred Securities will have no voting rights.
 
     Subject to the requirements of the second to last sentence of this
paragraph, the holders of a majority in aggregate liquidation amount of the
Preferred Securities have the right (i) on behalf of all holders of Preferred
Securities, to waive any past default that is waivable under the Declaration and
(ii) to direct the time, method and place of conducting any proceeding for any
remedy available to the Property Trustee, or exercising any trust or power
conferred upon the Property Trustee under the Declaration, including the right
to direct the Property Trustee, as the holder of the Junior Subordinated
Debentures, to (A) direct the time, method and place of conducting any
proceeding for any remedy available to the Indenture Trustee (as defined
herein), or executing any trust or power conferred on the Indenture Trustee with
respect to the Junior Subordinated Debentures, (B) waive any past default that
is waivable under Section 6.06 of the Indenture, or (C) exercise any right to
rescind or annul a declaration that the principal of all the Junior Subordinated
Debentures shall be due and payable; provided, however, that where a consent
under the Indenture would require the consent of (a) holders of Junior
Subordinated Debentures representing a specified percentage greater than a
majority in principal amount of the Junior Subordinated Debentures or (b) each
holder of Junior Subordinated Debentures affected thereby, no such consent shall
be given by the Property Trustee without the prior consent of, in the case of
clause (a) above, holders of Preferred Securities representing such specified
percentage of the aggregate liquidation amount of the Preferred Securities or,
in the case of clause (b) above, each holder of Preferred Securities affected
thereby. The Property Trustee shall not revoke any action previously authorized
or approved by a vote of the holders of Preferred Securities. The Property
Trustee shall notify all holders of record of Preferred Securities of any notice
of default received from the Indenture Trustee with respect to the
 
                                      S-18
<PAGE>   22
 
Junior Subordinated Debentures. Other than with respect to directing the time,
method and place of conducting any proceeding for any remedy available to the
Property Trustee or the Indenture Trustee as set forth above, the Property
Trustee shall be under no obligation to take any of the foregoing actions at the
direction of the holders of the Preferred Securities unless the Property Trustee
shall have obtained an opinion of nationally recognized independent tax counsel
recognized as expert in such matters to the effect that the Trust will not be
classified for United States Federal income tax purposes as an association
taxable as a corporation or a partnership on account of such action and will be
treated as a grantor trust for United States Federal income tax purposes
following such action. If the Property Trustee fails to enforce its rights under
the Declaration (including, without limitation, its rights, powers and
privileges as a holder of the Junior Subordinated Debentures under the
Indenture), any holder of Preferred Securities may, to the extent permitted by
applicable law, after a period of 30 days has elapsed from such holder's written
request to the Property Trustee to enforce such rights, institute a legal
proceeding directly against the Company to enforce the Property Trustee's rights
under the Declaration, without first instituting a legal proceeding against the
Property Trustee or any other person.
 
     A waiver of an Indenture Event of Default by the Property Trustee at the
direction of holders of the Preferred Securities will constitute a waiver of the
corresponding Event of Default under the Declaration in respect of the Trust
Securities.
 
   
     In the event the consent of the Property Trustee as the holder of the
Junior Subordinated Debentures is required under the Indenture with respect to
any amendment, modification or termination of the Indenture or the Junior
Subordinated Debentures, the Property Trustee shall request the direction of the
holders of the Trust Securities with respect to such amendment, modification or
termination and shall vote with respect to such amendment, modification or
termination as directed by a majority in liquidation amount of the Trust
Securities voting together as a single class; provided, however, that where any
such amendment, modification or termination under the Indenture would require
the consent or vote of (1) holders of Junior Subordinated Debentures
representing a specified percentage greater than a majority in principal amount
of the Junior Subordinated Debentures or (2) each holder of Junior Subordinated
Debentures, the Property Trustee may only give such consent or vote, in the case
of clause (1), at the direction of the holders of Trust Securities representing
such specified percentage of the aggregate liquidation amount of the Trust
Securities or, in the case of clause (2), as directed by each holder of Trust
Securities; and, provided further, however, that the Property Trustee shall be
under no obligation to take any such action in accordance with the directions of
the holders of the Trust Securities unless the Property Trustee has obtained an
opinion of nationally recognized independent tax counsel recognized as expert in
such matters to the effect that the Trust will not be classified for United
States Federal income tax purposes as an association taxable as a corporation or
a partnership on account of such action and will be treated as a grantor trust
for United States Federal income tax purposes following such action.
    
 
     Any required approval or direction of holders of Preferred Securities may
be given at a separate meeting of holders of Preferred Securities convened for
such purpose, at a meeting of all the holders of Trust Securities or pursuant to
written consent. The Regular Trustees will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be
mailed to each holder of record of Preferred Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken; (ii) a description of any resolution proposed
for adoption at such meeting on which such holders are entitled to vote or of
such matter upon which written consent is sought; and (iii) instructions for the
delivery of proxies or consents.
 
     No vote or consent of the holders of Preferred Securities will be required
for the Trust to redeem and cancel Preferred Securities or distribute Junior
Subordinated Debentures in accordance with the Declaration.
 
     Notwithstanding that holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities at such time that are owned by the Company or by any entity directly
or indirectly controlling or controlled by or under direct or indirect common
control
 
                                      S-19
<PAGE>   23
 
with the Company shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.
 
     The procedures by which persons owning Preferred Securities registered in
the name of and held by DTC or its nominee may exercise their voting rights are
described under "Description of Preferred Securities -- Book-Entry Only
Issuance; The Depository Trust Company" below.
 
     Holders of the Preferred Securities will have no rights to increase or
decrease the number of Trustees or to appoint, remove or replace a Trustee,
which rights are vested exclusively in the holders of the Common Securities.
 
MODIFICATION AND AMENDMENT OF THE DECLARATION
 
     The Declaration may be modified and amended with the approval of a majority
of the Regular Trustees, provided that, if any proposed modification or
amendment provides for, or the Regular Trustees otherwise propose to effect, (a)
any action that would adversely affect the powers, preferences or special rights
of the Trust Securities, whether by way of amendment to the Declaration or
otherwise, or (b) the dissolution, liquidation, winding-up or termination of the
Trust other than pursuant to the terms of the Declaration, then the holders of
the outstanding Trust Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of at least 66 2/3% in liquidation amount of the Trust
Securities, provided that if any amendment or proposal referred to above would
adversely affect only the Preferred Securities or the Common Securities, then
only the affected class will be entitled to vote on such amendment or proposal
and such amendment or proposal shall not be effective except with the approval
of 66 2/3% in liquidation amount of such class of Trust Securities.
 
     Notwithstanding the foregoing, (i) no amendment or modification may be made
to the Declaration unless the Regular Trustees shall have obtained (a) either a
ruling from the Internal Revenue Service or a written unqualified opinion of
nationally recognized independent tax counsel experienced in such matters to the
effect that such amendment will not cause the Trust to be classified for United
States Federal income tax purposes as an association taxable as a corporation or
a partnership and to the effect that the Trust will continue to be treated as a
grantor trust for purposes of United States Federal income taxation and (b) a
written unqualified opinion of nationally recognized independent counsel
experienced in such matters to the effect that such amendment will not cause the
Trust to be an "investment company" which is required to be registered under the
1940 Act; (ii) certain specified provisions of the Declaration may not be
amended without the consent of all the holders of the Trust Securities; (iii) no
amendment which adversely affects the rights, powers and privileges of the
Property Trustee shall be made without the consent of the Property Trustee; (iv)
Article IV of the Declaration relating to the obligation of the Company to
purchase the Common Securities and to pay certain obligations and expenses of
the Trust as described under "The PWG Trusts" in the accompanying Prospectus may
not be amended without the consent of the Company; and (v) the rights of holders
of Common Securities under Article V of the Declaration to increase or decrease
the number of, and to appoint, replace or remove, Trustees shall not be amended
without the consent of each holder of Common Securities.
 
     The Declaration further provides that it may be amended without the consent
of the holders of the Trust Securities to (i) cure any ambiguity; (ii) correct
or supplement any provision in the Declaration that may be defective or
inconsistent with any other provision of the Declaration; (iii) to add to the
covenants, restrictions or obligations of the Company; and (iv) to conform to
changes in, or a change in interpretation or application of, certain 1940 Act
requirements by the Securities and Exchange Commission (the "Commission"), which
amendment does not adversely affect the rights, preferences or privileges of the
holders.
 
BOOK-ENTRY ONLY ISSUANCE; THE DEPOSITORY TRUST COMPANY
 
     The Depository Trust Company ("DTC") will act as securities depositary for
the Preferred Securities. The Preferred Securities will be issued only as fully
registered securities registered in the name of DTC or its nominee. One or more
fully-registered global Preferred Securities certificates (each a "Preferred
Securities
 
                                      S-20
<PAGE>   24
 
Global Certificate"), representing the total aggregate number of Preferred
Securities, will be issued and will be deposited with DTC.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in a global Preferred
Security.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants ("Participants") deposit
with DTC. DTC also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations ("Direct Participants").
DTC is owned by a number of its Direct Participants and by the NYSE, the
American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc. Access to the DTC system is also available to others such as
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the Commission.
 
     Upon issuance of a Preferred Securities Global Certificate, DTC will credit
on its book-entry registration and transfer system the number of Preferred
Securities represented by such Preferred Securities Global Certificate to the
accounts of institutions that have accounts with DTC. Ownership of beneficial
interests in a Preferred Securities Global Certificate will be limited to
Participants or persons that may hold interests through Participants. The
ownership interest of each actual purchaser of each Preferred Security
("Beneficial Owner") is in turn to be recorded on the Direct Participants' and
the Indirect Participants' records. 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 Participants or the
Indirect Participants through which the Beneficial Owners purchased Preferred
Securities. Transfers of ownership interests in the Preferred Securities are to
be accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners.
 
     DTC has no knowledge of the actual Beneficial Owners of the Preferred
Securities; DTC's records reflect only the identity of the Direct Participants
to whose accounts such Preferred Securities 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. So long as DTC, or its
nominee, is the owner of a Preferred Securities Global Certificate, DTC or such
nominee, as the case may be, will be considered the sole owner and holder of
record of the Preferred Securities represented by such Preferred Securities
Global Certificate for all purposes.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices shall be sent to Cede & Co. If less than all the
Preferred Securities are being redeemed, DTC will reduce pro rata (subject to
adjustment to eliminate fractional Preferred Securities) the amount of interest
of each Direct Participant in the Preferred Securities to be redeemed.
 
     Although voting with respect to the Preferred Securities is limited, in
those instances in which a vote is required, neither DTC nor Cede & Co. itself
will consent or vote with respect to Preferred Securities. Under its usual
procedures, DTC would mail an omnibus proxy to the Trust 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
 
                                      S-21
<PAGE>   25
 
accounts the Preferred Securities are credited on the record date (identified in
a listing attached to the omnibus proxy).
 
     Distribution payments on the Preferred Securities represented by a
Preferred Securities Global Certificate will be made by the Property 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 Participants and not of DTC, the Trust or the Company, 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 Trust, 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 Participants and Indirect Participants.
 
     Except as provided herein, a Beneficial Owner in a Preferred Securities
Global Certificate will not be entitled to receive physical delivery of
Preferred Securities. Accordingly, each Beneficial Owner must rely on the
procedures of DTC to exercise any rights under the Preferred Securities.
 
     DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
the Trust. Under such circumstances, if a successor securities depositary is not
obtained, Preferred Security certificates will be required to be printed and
delivered. Additionally, the Trust may decide to discontinue use of the system
of book-entry transfers through DTC (or a successor depositary). In that event,
certificates for the Preferred Securities 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 Trust and the Company believe to be
reliable, but the Trust and the Company take no responsibility for the accuracy
thereof.
 
REGISTRAR, TRANSFER AGENT AND PAYING AGENT
 
     In the event the Preferred Securities do not remain in book-entry only
form, the following provisions will apply:
 
     Payment of distributions and payments on redemption of the Preferred
Securities will be payable, the transfer of the Preferred Securities will be
registrable and Preferred Securities will be exchangeable for Preferred
Securities of other denominations of a like aggregate liquidation amount at the
principal corporate trust office of the Property Trustee in The City of New
York; provided that payment of distributions may be made at the option of the
Regular Trustees on behalf of the Trust by check mailed to the address of the
persons entitled thereto and that the payment on redemption of any Preferred
Security will be made only upon surrender of such Preferred Security to the
Property Trustee.
 
     The Chase Manhattan Bank or one of its affiliates will act as registrar and
transfer agent for the Preferred Securities. The Chase Manhattan Bank will also
act as paying agent and, with the consent of the Regular Trustees, may designate
additional paying agents.
 
     Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of the Trust, but upon payment (with the giving of such
indemnity as the Trust or the Company may require) in respect of any tax or
other governmental charges that may be imposed in relation to it.
 
     The Trust will not be required to register or cause to be registered the
transfer of Preferred Securities after such Preferred Securities have been
called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
     The Property Trustee, prior to a default with respect to the Trust
Securities, undertakes to perform only such duties as are specifically set forth
in the Declaration and, after default, shall exercise the same degree of care as
a prudent individual would exercise in the conduct of his or her own affairs.
Subject to such provision,
 
                                      S-22
<PAGE>   26
 
the Property Trustee is under no obligation to exercise any of the powers vested
in it by the Declaration at the request of any holder of Preferred Securities,
unless offered reasonable indemnity by such holder against the costs, expenses
and liabilities which might be incurred thereby. The Property 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 Property Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
 
     The Property Trustee is a depositary for funds and performs other services
for, and transacts other banking business with, the Company in the normal course
of business.
 
GOVERNING LAW
 
     The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the laws of the State of Delaware.
 
MISCELLANEOUS
 
     The Regular Trustees are authorized and directed to take such action as
they deem reasonable in order that the Trust will not be deemed to be an
"investment company" required to be registered under the 1940 Act or that the
Trust will not be classified for United States Federal income tax purposes as an
association taxable as a corporation or a partnership and will be treated as a
grantor trust for United States Federal income tax purposes. In this connection,
the Regular Trustees are authorized to take any action, not inconsistent with
applicable law, the certificate of trust of the Trust or the Declaration, that
the Regular Trustees determine in their discretion to be reasonable and
necessary or desirable for such purposes, as long as such action does not
adversely affect the interests of holders of the Trust Securities.
 
     The Company and the Regular Trustees on behalf of the Trust will be
required to provide to the Property Trustee annually a certificate as to whether
or not the Company and the Trust, respectively, is in compliance with all the
conditions and covenants under the Declaration.
 
               DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES
 
     Set forth below is a description of the Junior Subordinated Debentures in
which the Trust will invest the proceeds from the issuance and sale of the Trust
Securities and which will be deposited in the Trust as trust assets. The terms
of the Junior Subordinated Debentures include those stated in the Indenture
dated as of             , 1996, between the Company and The Chase Manhattan
Bank, as trustee (the "Indenture Trustee"), as supplemented by the First
Supplemental Indenture dated as of             , 1996, between the Company and
the Indenture Trustee (as so supplemented, the "Indenture"), forms of which have
been filed as exhibits to the Registration Statement of which this Prospectus
Supplement forms a part, and those made part of the Indenture by the Trust
Indenture Act. This description supplements the description of the general terms
and provisions of the Subordinated Debt Securities set forth in the accompanying
Prospectus under the caption "Description of the Junior Subordinated Debt
Securities." The following description does not purport to be complete 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. Section references used herein are references to provisions of
the Indenture.
 
     The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that junior subordinated debentures
may be issued thereunder from time to time in one or more series (collectively,
together with the Junior Subordinated Debentures, the "Subordinated
Debentures"). The Junior Subordinated Debentures constitute a separate series
under the Indenture.
 
     Under certain circumstances involving the dissolution of the Trust
following the occurrence of a Special Event, Junior Subordinated Debentures may
be distributed to the holders of the Trust Securities upon dissolution of the
Trust. See "Description of the Preferred Securities -- Special Event Redemption
or Distribution."
 
                                      S-23
<PAGE>   27
 
GENERAL
 
     The Junior Subordinated Debentures are unsecured, subordinated obligations
of the Company, limited in aggregate principal amount to an amount equal to the
sum of (i) the stated liquidation amount of the Preferred Securities issued by
the Trust and (ii) the proceeds received by the Trust upon issuance of the
Common Securities to the Company (which proceeds will be used to purchase an
equal principal amount of Junior Subordinated Debentures).
 
     The entire principal amount of the Junior Subordinated Debentures will
become due and payable, together with any accrued and unpaid interest thereon,
on             , 2036. The Junior Subordinated Debentures are not subject to any
sinking fund.
 
     If Junior Subordinated Debentures are distributed to holders of Preferred
Securities upon dissolution of the Trust, such Junior Subordinated Debentures
will initially be issued as a Global Security (as defined below). As described
herein, under certain limited circumstances, Junior Subordinated Debentures may
be issued in certificated form in exchange for a Global Security. See
"Book-Entry and Settlement" below. In the event that Junior Subordinated
Debentures are issued in certificated form, such Junior Subordinated Debentures
will be in denominations of $25 and integral multiples thereof and may be
transferred or exchanged at the offices described below. Payments on Junior
Subordinated Debentures issued as a Global Security will be made to DTC, a
successor depositary or, in the event that no depositary is used, to a paying
agent for the Junior Subordinated Debentures.
 
     In the event that Junior Subordinated Debentures are issued in certificated
form, payments of principal and interest will be payable, the transfer of the
Junior Subordinated Debentures will be registrable and Junior Subordinated
Debentures will be exchangeable for Junior Subordinated Debentures of other
denominations of a like aggregate principal amount at the corporate trust office
of the Indenture Trustee in The City of New York; provided that payment of
interest may be made at the option of the Company by check mailed to the address
of the persons entitled thereto and that the payment of principal with respect
to any Junior Subordinated Debenture will be made only upon surrender of such
Junior Subordinated Debenture to the Indenture Trustee.
 
     If the Junior Subordinated Debentures are distributed to the holders of
Preferred Securities upon dissolution of the Trust, the Company will use its
best efforts to list the Junior Subordinated Debentures on the NYSE or on such
other exchange on which the Preferred Securities are then listed.
 
OPTIONAL REDEMPTION
 
     Except as provided below, the Junior Subordinated Debentures may not be
redeemed prior to             , 2001. The Company shall have the right to redeem
the Junior Subordinated Debentures, in whole or in part, from time to time, on
or after             , 2001, upon not less than 30 nor more than 60 days notice,
at a redemption price equal to 100% of the principal amount to be redeemed, plus
any accrued and unpaid interest to the redemption date, including interest
accrued during an Extension Period. The Company will also have the right to
redeem the Junior Subordinated Debentures at any time upon the occurrence of a
Tax Event if certain conditions are met as described under "Description of the
Preferred Securities -- Special Event Redemption or Distribution."
 
     If the Company gives a notice of redemption in respect of Junior
Subordinated Debentures (which notice will be irrevocable) then, by 12:00 noon,
New York City time, on the redemption date, the Company will deposit irrevocably
with the Indenture Trustee funds sufficient to pay the applicable redemption
price and will give irrevocable instructions and authority to pay such
redemption price to the holders of the Junior Subordinated Debentures. If notice
of redemption shall have been given and funds deposited as required, then, upon
the date of such deposit, interest will cease to accrue on the Junior
Subordinated Debentures called for redemption, such Junior Subordinated
Debentures will no longer be deemed to be outstanding and all rights of holders
of such Junior Subordinated Debentures so called for redemption will cease,
except the right of the holders of such Junior Subordinated Debentures to
receive the applicable redemption price, but without interest on such redemption
price. If any date fixed for redemption of Junior Subordinated Debentures is not
a
 
                                      S-24
<PAGE>   28
 
   
Business Day, then payment of the redemption price payable on such date will be
made on the next succeeding day that 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 each case with the same force and effect as if made
on such date fixed for redemption. If payment of the redemption price in respect
of Junior Subordinated Debentures is refused and not paid by the Company,
interest on such Junior Subordinated Debentures will continue to accrue, from
the original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the applicable redemption price. If fewer than all the Junior
Subordinated Debentures are to be redeemed, the Junior Subordinated Debentures
to be redeemed shall be selected by lot or pro rata or in some other equitable
manner determined by the Indenture Trustee.
    
 
   
     In the event of any redemption in part, the Company shall not be required
to (i) issue, register the transfer of or exchange any Junior Subordinated
Debentures during a period beginning at the opening of business 15 days before
the day of the mailing of a notice of redemption of all or less than all of the
Junior Subordinated Debentures and ending at the close of business on the day of
such mailing and (ii) register the transfer of or exchange any Junior
Subordinated Debentures so selected for redemption, in whole or in part, except
the unredeemed portion of any Junior Subordinated Debentures being redeemed in
part. (Section 2.05)
    
 
INTEREST
 
   
     The Junior Subordinated Debentures will bear interest at the rate of      %
per annum from             , 1996. Interest will be payable monthly in arrears
on the first day of each month (each, an "Interest Payment Date"), commencing on
            , 1996, to the person in whose name such Junior Subordinated
Debenture is registered, subject to certain exceptions, at the close of business
on the Business Day next preceding such Interest Payment Date. In the event (i)
the Preferred Securities shall not continue to remain in book-entry only form or
(ii) if, following distribution of the Junior Subordinated Debentures to holders
of Trust Securities upon dissolution of the Trust as described under
"Description of the Preferred Securities," the Junior Subordinated Debentures
shall not continue to remain in book-entry only form, the relevant record date
will be the fifteenth day of the month immediately preceding the month in which
the relevant Interest Payment Date occurs. Interest payable on any Junior
Subordinated Debenture that is not punctually paid or duly provided for on any
interest payment date will forthwith cease to be payable to the person in whose
name such Junior Subordinated Debenture is registered on the relevant record
date, and such defaulted interest will instead be payable to the person in whose
name such Junior Subordinated Debenture is registered on the special record date
or other specified date determined in accordance with the Indenture; provided,
however, that interest, shall not be considered payable by the Company on any
Interest Payment Date falling within an Extension Period unless the Company has
elected to make a full or partial payment of interest accrued on the Junior
Subordinated Debentures on such Interest Payment Date.
    
 
   
     The amount of interest payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months and for any period shorter than a
30-day monthly interest period for which interest is computed, the amount of
interest payable will be computed on the basis of the actual number of days
elapsed. If any date on which interest is payable on the Junior Subordinated
Debentures is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay), except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date.
    
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
   
     So long as the Company is not in default in the payment of interest on the
Junior Subordinated Debentures, the Company shall have the right to extend the
interest payment period from time to time for a period not exceeding 60
consecutive monthly interest periods. The Company has no current intention of
exercising its right to extend an interest payment period. No interest shall be
due and payable during an Extension Period, except at the end thereof. During
any Extension Period, the Company shall not declare or
    
 
                                      S-25
<PAGE>   29
 
pay any dividends on, or redeem, purchase, acquire or make a distribution or
liquidation payment with respect to, any of its common stock or preferred stock
or make any guarantee payments with respect thereto; provided, however, that the
foregoing restrictions shall not apply to (i) dividends, redemptions, purchases,
acquisitions, distributions or payments made by the Company by way of issuance
of shares of its capital stock, (ii) payments of accrued dividends by the
Company upon the redemption, exchange or conversion of any preferred stock of
the Company as may be outstanding from time to time in accordance with the terms
of such preferred stock or (iii) cash payments made by the Company in lieu of
delivering fractional shares upon the redemption, exchange or conversion of any
preferred stock of the Company as may be outstanding from time to time in
accordance with the terms of such preferred stock.
 
     The Company's outstanding preferred stock consists of $100 million stated
value of 6% Cumulative Convertible Redeemable Preferred Stock, Series A (the
"Convertible Preferred Stock") and $250 million stated value of 9% Cumulative
Redeemable Preferred Stock, Series C (the "Redeemable Preferred Stock"). The
Convertible Preferred Stock is redeemable at any time, in whole or in part, at
the option of the Company at redemption prices declining to $100 per share, plus
accrued and unpaid dividends, by December 16, 2004 and is subject to mandatory
redemption on December 15, 2014. The Convertible Preferred Stock is convertible,
at the option of the holder, into shares of common stock, at any time, in whole
or in part, at a conversion price of $18.13 per share of common stock, subject
to adjustment. The Redeemable Preferred Stock is redeemable, at the option of
the Company, at any time after December 15, 1999, in whole or in part, at a
price of $100 per share, together with accrued but unpaid dividends. The
Redeemable Preferred Stock is subject to mandatory redemption on December 15,
2014.
 
   
     Prior to the termination of any such Extension Period, the Company may
further extend the interest payment period; provided that such Extension Period
together with all such previous and further extensions thereof may not exceed 60
consecutive monthly interest periods and may not extend beyond the maturity of
the Junior Subordinated Debentures. On the first Interest Payment Date occurring
at or after the end of each Extension Period, the Company shall pay to the
holders of Junior Subordinated Debentures of record on the record date for such
Interest Payment Date (regardless of who the holders of record may have been on
other dates during the Extension Period) all accrued and unpaid interest on the
Junior Subordinated Debentures, together with interest thereon at the rate
specified for the Junior Subordinated Debentures to the extent permitted by
applicable law, compounded monthly ("Compounded Interest"). Upon the termination
of any Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements. The Company
may also prepay at any time all or any portion of the interest accrued during an
Extension Period. Consequently, there could be multiple Extension Periods of
varying lengths throughout the term of the Junior Subordinated Debentures, each
not to exceed 60 consecutive monthly interest periods or to cause any extension
beyond maturity of the Junior Subordinated Debentures. The failure by the
Company to make interest payments during an Extension Period would not
constitute a default or an event of default under the Indenture or the Company's
currently outstanding indebtedness.
    
 
   
     If the Property Trustee shall be the sole holder of the Junior Subordinated
Debentures, the Company shall give the Property Trustee notice of its selection
of such Extension Period one Business Day prior to the earlier of (i) the next
succeeding date on which the distributions on the Preferred Securities are
payable or (ii) the date the Trust is required to give notice to the NYSE (if
the Preferred Securities are then listed thereon) or other applicable
self-regulatory organization or to holders of the Preferred Securities of the
record date or payment date for such distribution. The Trust shall give notice
of the Company's selection of such Extension Period to the holders of the
Preferred Securities.
    
 
   
     If Junior Subordinated Debentures have been distributed to holders of Trust
Securities, the Company shall give the holders of the Junior Subordinated
Debentures notice of its selection of such Extension Period ten Business Days
prior to the earlier of (i) the next succeeding Interest Payment Date or (ii)
the date the Company is required to give notice to the NYSE (if the Junior
Subordinated Debentures are then listed thereon) or other applicable
self-regulatory organization or to holders of the Junior Subordinated Debentures
of the record or payment date for such related interest payment.

COMPOUNDED INTEREST
 
     Payments of Compounded Interest on the Junior Subordinated Debentures held
by the Trust will make funds available to pay any interest on distributions in
arrears in respect of the Preferred Securities pursuant to the terms thereof.
 
BOOK-ENTRY AND SETTLEMENT
 
     If any Junior Subordinated Debentures are distributed to holders of
Preferred Securities (see "Description of the Preferred Securities"), such
Junior Subordinated Debentures will be issued in the form of one or more global
certificates (each a "Global Security") registered in the name of the depositary
or its nominee. Except under the limited circumstances described below, Junior
Subordinated Debentures represented by the Global Security will not be
exchangeable for, and will not otherwise be issuable as, Junior Subordinated
Debentures in definitive form. The Global Securities described above may not be
transferred except by the depositary to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the depositary
or to a successor depositary or its nominee.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.
 
   
     Except as provided below, owners of beneficial interests in such a Global
Security will not be entitled to receive physical delivery of Junior
Subordinated Debentures in definitive form and will not be considered the
holders (as defined in the Indenture) thereof for any purpose under the
Indenture, and no Global Security representing Junior Subordinated Debentures
shall be exchangeable, except for another Global Security of like denomination
and tenor to be registered in the name of the depositary or its nominee or to a
successor depositary or its nominee. Accordingly, each Beneficial Owner must
rely on the procedures of the depositary or if such person is not a Participant,
on the procedures of the Participant through which such person owns its interest
to exercise any rights of a holder under the Indenture. If Junior Subordinated
Debentures are distributed to holders of Preferred Securities, DTC will act as
securities depositary for the Junior Subordinated Debentures.
    
 
     For a description of DTC and DTC's book-entry system, see "Description of
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company." As of the date of this Prospectus Supplement, the description herein
of DTC's book-entry system and DTC's practices as they relate to purchases,
transfers, notices and payments with respect to the Preferred Securities apply
in all material respects to any debt obligations represented by one or more
Global Securities held by DTC. The Company may appoint a successor to DTC or any
successor depositary in the event DTC or such successor depositary is unable or
unwilling to continue as a depositary for the Global Securities.
 
     None of the Company, the Indenture Trustee, any paying agent and any other
agent of the Company or the Indenture Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Security for such Junior
Subordinated Debentures or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.
 
     A Global Security shall be exchangeable for Junior Subordinated Debentures
registered in the names of persons other than the depositary or its nominee only
if (i) the depositary notifies the Company that it is unwilling or unable to
continue as a depositary for such Global Security and no successor depositary
shall have been appointed; (ii) the depositary, at any time, ceases to be a
clearing agency registered under the Exchange Act at which time the depositary
is required to be so registered to act as such depositary and no successor
depositary shall have been appointed; (iii) the Company, in its sole discretion,
determines that such Global Security shall be so exchangeable; or (iv) there
shall have occurred an Indenture Event of Default with respect to such Junior
Subordinated Debentures. Any Global Security that is exchangeable pursuant to
the preceding sentence shall be exchangeable for Junior Subordinated Debentures
registered in such names as the
 
                                      S-27
<PAGE>   31
 
depositary shall direct. It is expected that such instructions will be based
upon directions received by the depositary from its Participants with respect to
ownership of beneficial interests in such Global Security.
 
                 RELATIONSHIP BETWEEN THE PREFERRED SECURITIES,
                     THE JUNIOR SUBORDINATED DEBENTURES AND
                       THE PREFERRED SECURITIES GUARANTEE
 
     As set forth in the Declaration, the Trust exists for the sole purpose of
(a) issuing and selling the Trust Securities evidencing undivided beneficial
interests in the assets of the Trust and investing the proceeds from such
issuance and sale in the Junior Subordinated Debentures and (b) engaging in such
other activities as are necessary, convenient or incidental thereto.
 
   
     As long as payments of interest and other payments are made when due on the
Junior Subordinated Debentures, such payments will be sufficient to cover
distributions and other payments due on the Preferred Securities primarily
because (i) the aggregate principal amount of Junior Subordinated Debentures
held as trust assets will be equal to the sum of the aggregate stated
liquidation amount of the Trust Securities; (ii) the interest rate and interest
and other payment dates on the Junior Subordinated Debentures will match the
distribution rate and distribution and other payment dates for the Preferred
Securities; (iii) the Declaration provides that the Company shall pay for all
debts and obligations (other than with respect to the Trust Securities) and all
costs and expenses of the Trust, including any taxes and all costs and expenses
with respect thereto, to which the Trust may become subject, except for United
States withholding taxes; and (iv) the Declaration further provides that the
Trustees shall not cause or permit the Trust, among other things, to engage in
any activity that is not consistent with the limited purposes of the Trust. With
respect to clause (iii) above, however, no assurance can be given that the
Company will have sufficient resources to enable it to pay such debts,
obligations, costs and expenses on behalf of the Trust.
    
 
   
     Payments of distributions and other payments due on the Preferred
Securities are guaranteed by the Company on a subordinated basis as and to the
extent set forth under "Description of the Preferred Securities Guarantees," in
the accompanying Prospectus. If the Company does not make interest or other
payments on the Junior Subordinated Debentures, the Trust will not make
distributions or other payments on the Preferred Securities. Under the
Declaration, if and to the extent the Company does make interest or other
payments on the Junior Subordinated Debentures, the Property Trustee is
obligated to make distributions or other payments on the Preferred Securities.
The Preferred Securities Guarantee is a full and unconditional guarantee from
the time of issuance of the Preferred Securities, but the Preferred Securities
Guarantee covers distributions and other payments on the Preferred Securities
only if and to the extent that the Company has made a payment to the Property
Trustee of interest or principal on the Junior Subordinated Debentures deposited
in the Trust as trust assets.
    
 
   
     The Property Trustee will have the power to exercise all rights, powers and
privileges under the Indenture with respect to the Junior Subordinated
Debentures, including its rights as the holder of the Junior Subordinated
Debentures to enforce the Company's obligations under the Junior Subordinated
Debentures upon the occurrence of an Indenture Event of Default, and will also
have the right to enforce the Preferred Securities Guarantee on behalf of the
holders of the Preferred Securities. In addition, the holders of at least a
majority in liquidation amount of the Preferred Securities will have the right
to direct the Property Trustee with respect to certain matters under the
Declaration and the Preferred Securities Guarantee. If the Property Trustee
fails to enforce its rights under the Indenture, any holder of Preferred
Securities may, to the extent permitted by applicable law, after a period of 30
days has elapsed from such holder's written request to the Property Trustee to
enforce such rights, institute a legal proceeding against the Company to enforce
the Property Trustee's rights under the Junior Subordinated Debentures without
first instituting any legal proceeding against the Property Trustee or any other
person or entity. Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Junior Subordinated Debentures on
the date such interest or principal is otherwise payable (or in the case of
redemption, the redemption date), then a holder of Preferred Securities may
directly institute suit against the Company for enforcement of payment to such
holder of the principal of
    
 
                                      S-28
<PAGE>   32
 
   
or interest on Junior Subordinated Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities held by such holder
on or after the respective due date specified in the Junior Subordinated
Debentures. The holders of Preferred Securities will not be able to exercise
directly against the Company any other remedy available to the holders of the
Junior Subordinated Debentures unless the Property Trustee first fails to do so.
If the Property Trustee fails to enforce the Preferred Securities Guarantee, to
the extent permitted by applicable law, any holder of Preferred Securities may
institute a legal proceeding directly against the Company to enforce the
Property Trustee's rights under the Preferred Securities Guarantee without first
instituting a legal proceeding against the Trust, the Property Trustee or any
other person or entity. Notwithstanding the foregoing, if the Company has failed
to make a Guarantee Payment, a holder of Preferred Securities may directly
institute a proceeding against the Company for enforcement of such holder's
right to receive payment under the Guarantee. The Company waives any right or
remedy to require that any action be brought first against the Trust or any
other person or entity before proceeding directly against the Company. See
"Description of the Preferred Securities" and "Description of the Preferred
Securities Guarantees" in the accompanying Prospectus.
    
 
     The above mechanisms and obligations, taken together, provide a full and
unconditional guarantee by the Company of payments due on the Preferred
Securities.

                                    TAXATION
 
   
     In the opinion of Cravath, Swaine & Moore, counsel to the Company and the
Trust ("Tax Counsel"), the following are the material United States Federal
income tax consequences of the ownership and disposition of Preferred
Securities. Unless otherwise stated, this summary deals only with Preferred
Securities held as capital assets by holders who acquire the Preferred
Securities upon original issuance ("Initial Holders"). It does not deal with
special classes of holders, such as dealers in securities or currencies, life
insurance companies, persons holding Preferred Securities as part of a straddle
or as part of a hedging or conversion transaction, or persons whose functional
currency is not the United States dollar. This summary is based on the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury Regulations thereunder
and administrative and judicial interpretations thereof are of the date hereof,
all of which are subject to change (possibly on a retroactive basis).
    
 
     INVESTORS ARE ADVISED TO CONSULT THEIR TAX ADVISORS AS TO THE UNITED STATES
FEDERAL INCOME TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF PREFERRED
SECURITIES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE EFFECT OF
ANY STATE, LOCAL OR OTHER TAX LAWS.
 
CLASSIFICATION OF THE TRUST
 
   
     In the opinion of Tax Counsel, under current law and assuming full
compliance with the terms of the Declaration, the Trust will be classified for
United States Federal income tax purposes as a grantor trust and not as an
association taxable as a corporation. Accordingly, each holder of Preferred
Securities (a "Securityholder") will be considered the owner of a pro rata
portion of the Junior Subordinated Debentures held by the Trust. Accordingly,
each Securityholder will be required to include in gross income the pro rata
share of income accrued on the Junior Subordinated Debentures.
    
 
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
   
     In the opinion of Tax Counsel, under current law and assuming full
compliance with the Indenture, the Junior Subordinated Notes will be classified
for United States Federal income tax purposes as indebtedness of the Company.
    
 
   
INTEREST AND ORIGINAL ISSUE DISCOUNT
    
 
   
     If an Extension Period occurs, the Junior Subordinated Debentures would be
considered to have original issue discount at all times after the beginning of
the first Extension Period, including after the termination of the Extension
Period. In addition, the Company's option to defer the payment of interest on
the Junior Subordinated Debentures during an Extension Period might cause the
Junior Subordinated Debentures to be considered initially to be issued with
original issue discount. The Company believes, and will take the position, that
this latter result will not arise because of an exception in the Treasury
Regulations that applies when there is only a "remote" likelihood that an
Extension Period will occur. Assuming that the likelihood of an Extension Period
is in fact remote, Tax Counsel believes that this position is correct although
there is no authority directly on point and the Internal Revenue Service could
take a contrary position.
    
 
   
     If the original issue discount rules apply to the Junior Subordinated
Debentures (either following the occurrence of an Extension Period or
initially), each Securityholder, whether on the cash or accrual method of
accounting, will be required to accrue its pro rata share of original issue
discount into income in accordance with a constant yield method based on the
compounding of interest. As a result, income will be required to be reported by
Securityholders before the receipt of cash attributable to such income, and, in
particular, income will be reported during an Extension Period even though no
cash distributions are being made. If the original issue discount rules apply
for a period during which cash distributions are currently being made, the sum
of the daily accruals of income for a monthly period for a Securityholder that
purchased the Preferred Securities for their liquidation value will equal the
cash distribution received by the Securityholder for such month, assuming no
disposition prior to the record date for such distribution.
    
 
                                      S-30
<PAGE>   34
 
   
     If the original issue discount rules apply, actual distributions of stated
interest will not separately be reported as income. In that case, a
Securityholder's tax basis for the Junior Subordinated Debentures will be
increased by original issue discount accrued into income, and decreased by cash
distributions of interest. If the original issue discount rules do not apply,
stated interest will be includible in a Securityholder's gross income as
ordinary interest income in accordance with such holder's regular method of tax
accounting.
    
 
   
     Whether or not the original issue discount rules apply, no portion of the
amounts received on the Preferred Securities will be eligible for the corporate
dividends received deduction.
    
 
   
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF PREFERRED
SECURITIES
    
 
   
     Under current law, a distribution by the Trust of the Junior Subordinated
Debentures as described under the caption "Description of the Preferred
Securities--Special Event Redemption or Distribution" will be non-taxable and
will result in the Securityholder receiving directly such Securityholder's pro
rata share of the Junior Subordinated Debentures previously held indirectly
through the Trust, with a holding period and tax basis equal to the holding
period and adjusted tax basis such Securityholder was considered to have had in
such Securityholder's pro rata share of the underlying Junior Subordinated
Debentures immediately prior to such distribution. If, however, the Special
Event giving rise to the distribution is a Tax Event which results in the Trust
being treated as an association taxable as a corporation, the distribution would
constitute a taxable event to holders of the Preferred Securities.
    
 
MARKET DISCOUNT AND BOND PREMIUM
 
     Securityholders other than Initial Holders may be considered to have
acquired their pro rata interest in the Junior Subordinated Debentures with
market discount, acquisition premium or amortizable bond premium. Such holders
are advised to consult their tax advisors as to the income tax consequences of
the acquisition, ownership and disposition of the Preferred Securities.
 
DISPOSITION OF THE PREFERRED SECURITIES
 
   
     Upon a sale, exchange or other disposition of the Preferred Securities
(including a distribution of cash in redemption of a Securityholder's Preferred
Securities upon redemption or repayment of the underlying Junior Subordinated
Debentures, but excluding the distribution of Junior Subordinated Debentures), a
Securityholder will be considered to have disposed of all or part of such
Securityholder's pro rata share of the Junior Subordinated Debentures, and will
recognize gain or loss equal to the difference between the amount realized
(other than amounts attributable to accrued but unpaid interest that is not
treated as original issue discount) and the Securityholder's adjusted tax basis
in such Securityholder's pro rata share of the underlying Junior Subordinated
Debentures deemed disposed of. A holder's adjusted tax basis in the Preferred
Securities generally will be its initial purchase price increased by original
issue discount previously includible in such holder's gross income to the date
of disposition and decreased by payments (other than payments of stated interest
that are not treated as original issue discount) received on the Preferred
Securities. Gain or loss will be capital gain or loss (except to the extent of
any accrued interest or market discount not previously included in income). See
"Market Discount and Bond Premium" above. Such gain or loss will be long-term
capital gain or loss if the Preferred Securities have been held for more than
one year.
    
 
   
UNITED STATES ALIEN HOLDERS
    
 
   
     For purposes of this discussion, a "United States Alien Holder" is any
individual, corporation, partnership, estate or trust that is, as to the United
States, a non-resident alien individual or a foreign corporation, partnership,
estate or trust.
    
 
     Under present United States Federal income tax law:
 
   
          (i) payments by the Trust or any of its paying agents to any holder of
     a Preferred Security who or which is a United States Alien Holder will not
     be subject to United States Federal income or withholding tax, provided
     that (a) the beneficial owner of the Preferred Security does not actually
     or constructively
    
 
                                      S-31
<PAGE>   35
 
     own 10% or more of the total combined voting power of all classes of stock
     of the Company entitled to vote; (b) the beneficial owner of the Preferred
     Security is not a controlled foreign corporation that is related to the
     Company through stock ownership; and (c) either (A) the beneficial owner of
     the Preferred Security certifies to the Trust or its agent, under penalties
     of perjury, that it is not a United States holder and provides its name and
     address or (B) 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 Preferred
     Security certifies to the Trust or its agent under penalties of perjury
     that such statement has been received from the beneficial owner by it or by
     a Financial Institution between it and the beneficial owner and furnishes
     the Trust or its agent with a copy thereof; and
 
   
          (ii) A United States Alien Holder of a Preferred Security will not be
     subject to United States Federal income or withholding tax on any gain
     realized upon the sale or other disposition of a Preferred Security unless
     (i) the United States Alien Holder is an individual who is present in the
     United States for 183 days or more in the taxable year of disposition, and
     certain other conditions apply, or (ii) the gain is effectively connected
     with the conduct by the United States Alien Holder of a trade or business
     in the United States.
    
 
INFORMATION REPORTING TO HOLDERS
 
   
     The Trust will report the interest paid or the original issue discount that
accrued during the year with respect to the Junior Subordinated Debentures, and
any gross proceeds received by the Trust from the retirement or redemption of
the Junior Subordinated Debentures, annually to the holders of record of the
Preferred Securities and the Internal Revenue Service. The Trust currently
intends to deliver such reports to holders of record prior to January 31
following each calendar year.
    
 
BACKUP WITHHOLDING
 
     Payments made on, and proceeds from the sale of, Preferred Securities may
be subject to a "backup" withholding tax of 31% unless the holder complies with
certain identification requirements. Any withheld amounts will generally be
allowed as a credit against the holder's Federal income tax, provided the
required information is timely filed with the Internal Revenue Service.
 
POSSIBLE TAX LAW CHANGES
 
   
     On March 19, 1996, as part of President Clinton's Fiscal 1997 Budget
Proposal, the Clinton Administration proposed legislation (the "Proposed
Legislation") which would, among other things, generally deny corporate issuers
a deduction for interest in respect of certain debt obligations, such as the
Junior Subordinated Debentures, issued on or after December 7, 1995 if such debt
obligations have a maximum term in excess of 20 years and are not shown as
indebtedness on the issuer's applicable consolidated balance sheet. On March 29,
1996, Senate Finance Committee Chairman William V. Roth, Jr. and House Ways and
Means Committee Chairman Bill Archer issued a joint statement (the "Joint
Statement") indicating their intent that the Proposed Legislation, if adopted by
either of the tax-writing committees of Congress, would have an effective date
that is no earlier than the date of "appropriate Congressional action." In
addition, subsequent to the publication of the Joint Statement, Senator Daniel
Patrick Moynihan and Representatives Sam M. Gibbons and Charles B. Rangel wrote
letters to the Treasury Department (the "Democrat Letters"), which concurred
with the view expressed in the Joint Statement. No such Congressional action has
yet occurred. If the principles contained in the Joint Statement and the
Democrat Letters were followed and if the Proposed Legislation were enacted,
such legislation would not apply to the Junior Subordinated Debentures. There
can be no assurance, however, that the effective date guidance contained in the
Joint Statement and the Democrat Letters will be incorporated into the Proposed
Legislation, if enacted, or that other legislation enacted after the date hereof
will not otherwise adversely affect the ability of the Company to deduct the
interest payable on the Junior Subordinated Debentures. Such a change could give
rise to a Tax Event. See "Description of the Preferred Securities -- Special
Event Redemption or Distribution."

</TABLE>
 
     In the Underwriting Agreement, the several Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all the
Preferred Securities offered hereby if any Preferred Securities are purchased by
the Underwriters. In the event of default by an Underwriter, the Underwriting
Agreement provides that, in certain circumstances, the purchase commitment of
the nondefaulting Underwriters may be increased or the Underwriting Agreement
may be terminated.
 
     The Company has been advised by the Representative that the Underwriters
propose initially to offer the Preferred Securities to the public at the public
offering price set forth on the cover page of this Prospectus Supplement, and to
certain dealers at such price less a concession not in excess of $          per
Preferred Security. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of $          per Preferred Security to certain brokers
and dealers. After the initial public offering, the public offering price and
such concessions may be changed.
 
   
     In view of the fact that the proceeds of the sale of the Preferred
Securities will be used to purchase the Junior Subordinated Debentures of the
Company, the Underwriting Agreement provides that the Company will pay as
compensation ("Underwriters' Compensation") for the Underwriters' arranging the
investment therein of such proceeds $          per Preferred Security or
$          in the aggregate ($          in the aggregate if the Underwriters'
over-allotment option is exercised in full) for the accounts of the several
Underwriters.
    
 
   
     Pursuant to the Underwriting Agreement, the Trust has granted to the
Underwriters an option, exercisable for 30 days from the date hereof, to
purchase up to             additional Preferred Securities at the price to
public set forth on the cover page hereof. The Underwriters may exercise such
option to purchase solely for the purpose of covering over-allotments, if any,
made in connection with the offering. The Company will pay Underwriters'
Compensation in the amount per Preferred Security set forth above with respect
to such additional Preferred Securities. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional Preferred
Securities as the number set forth next to such Underwriter's name in the
preceding table bears to the total number of Preferred Securities offered by the
Underwriters hereby.
    
 
   
     During a period of 30 days from the date of this Prospectus Supplement,
neither the Trust nor the Company will, without the prior written consent of the
Representative, directly or indirectly, sell, offer to sell, grant any option
for the sale of, or otherwise dispose of, any Preferred Securities, any security
convertible into or exchangeable into or exercisable for Preferred Securities or
Junior Subordinated Debentures or any debt securities substantially similar to
the Junior Subordinated Debentures or equity securities substantially similar to
the Preferred Securities (except for the Junior Subordinated Debentures and the
Preferred Securities offered hereby).

     The Preferred Securities have been approved for listing on the NYSE under
the symbol "PWJ PrA", subject to official notice of issuance. Trading of the
Preferred Securities on the NYSE is expected to commence within a 30-day period
after the date of this Prospectus Supplement. PaineWebber has advised the Trust
that it intends to make a market in the Preferred Securities. PaineWebber will
have no obligation to make a market in the Preferred Securities, however, and
may cease market making activities, if commenced, at any time.
    
 
   
     Prior to this offering, there has been no public market for the Preferred
Securities. In order to meet one of the requirements for listing the Preferred
Securities on the NYSE, the Underwriters represented that, at the time of the
consummation of the offering of the Preferred Securities, there will be at least
400 holders of Preferred Securities.
    
 
     The Representative is a wholly-owned subsidiary of the Company. The
underwriting of the Preferred Securities offered hereby is being conducted in
accordance with Rule 2720 of the NASD Conduct Rules.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, or
contribute to payments which the Underwriters may be required to make in respect
thereof.

                            PAINE WEBBER GROUP INC.
 
    Paine Webber Group Inc. (the "Company") may offer, from time to time, junior
subordinated debt securities (the "Junior Subordinated Debt Securities")
consisting of debentures, notes or other evidences of indebtedness in one or
more series and in amounts, at prices and on terms to be determined at or prior
to the time of any such offering. The Junior Subordinated Debt Securities when
issued will be unsecured obligations of the Company. The Company's obligations
under the Junior Subordinated Debt Securities will be subordinate and junior in
right of payment to all Senior Indebtedness (as defined herein) of the Company.
 
   
    PWG Capital Trust I, PWG Capital Trust II, PWG Capital Trust III and PWG
Capital Trust IV (the "PWG Trusts"), each a business trust formed under the laws
of the State of Delaware, may offer and sell, from time to time, preferred
securities ("Preferred Securities") representing undivided beneficial interests
in the assets of the respective PWG Trust. The payment of periodic cash
distributions ("distributions") with respect to Preferred Securities of a PWG
Trust out of moneys held by the Property Trustee (as defined herein) and
payments on liquidation of such PWG Trust and on redemption of Preferred
Securities of such PWG Trust will be guaranteed by the Company on a subordinated
basis as and to the extent described herein (each such guarantee, a "Preferred
Securities Guarantee"). See "Description of the Preferred Securities
Guarantees". The Preferred Securities Guarantee covers payments of distributions
and other payments on the Preferred Securities only if and to the extent that
the applicable PWG Trust has funds available therefor which will not be the case
unless the Company has made a payment of interest or principal or other payments
on the Junior Subordinated Debt Securities held by such PWG Trust as its sole
asset. The Preferred Securities Guarantees, when taken together with the
Company's obligations under the Junior Subordinated Debt Securities held by a
PWG Trust and the Indenture (as defined herein) and its obligations under the
Amended and Restated Declaration of such PWG Trust, including its obligation to
pay all costs, expenses, debts and other obligations of such PWG Trust (other
than with respect to the Trust Securities (as defined herein)), will provide a
full and unconditional guarantee of amounts due on the Preferred Securities of
such PWG Trust. Junior Subordinated Debt Securities may be issued and sold, from
time to time, in one or more series by the Company to a PWG Trust, or a trustee
of such PWG Trust, in connection with the investment of the proceeds from the
offering of Preferred Securities and Common Securities (as defined herein) of
such PWG Trust. The Junior Subordinated Debt Securities purchased by a PWG Trust
may be subsequently distributed pro rata to holders of Preferred Securities and
Common Securities of such PWG Trust in connection with the dissolution of such
PWG Trust upon the occurrence of certain events as may be described in an
accompanying Prospectus Supplement.
    
 
    Specific terms of the Junior Subordinated Debt Securities of any series or
the Preferred Securities of any PWG Trust in respect of which this Prospectus is
being delivered (the "Offered Securities") will be set forth in a Prospectus
Supplement with respect to such Offered Securities, which will describe, without
limitation and where applicable, the following: (i) in the case of Junior
Subordinated Debt Securities, the specific designation, aggregate principal
amount, authorized denomination, maturity, premium, if any, redemption or
sinking fund provisions, if any, interest rate (which may be fixed or variable),
if any, time and method of calculating interest payments, if any, dates on which
premium, if any, and interest, if any, will be payable, right of the Company, if
any, to defer payment of interest on the Junior Subordinated Debt Securities and
the maximum length of such deferral period, the initial public offering price,
and any listing on a securities exchange and other specific terms of the
offering; and (ii) in the case of Preferred Securities, the specific
designation, number of securities, liquidation amount per security, initial
public offering price, and any listing on a securities exchange, distribution
rate (or method of calculation thereof), dates on which distributions shall be
payable and dates from which distributions shall accrue, voting rights (if any),
terms for any conversion or exchange into other securities, any redemption or
sinking fund provisions, any other rights, preferences, privileges, limitations
or restrictions relating to the Preferred Securities and the terms upon which
the proceeds of the sale of the Preferred Securities shall be used to purchase a
specific series of Junior Subordinated Debt Securities of the Company. Unless
otherwise indicated in an accompanying Prospectus Supplement, the Company does
not intend to list any of the Offered Securities on a national securities
exchange.
 
    The Offered Securities may be offered in amounts, at prices and on terms to
be determined at the time of offering. Any Prospectus Supplement relating to any
series of Offered Securities will contain information concerning certain United
States Federal income tax considerations, if applicable, to the Offered
Securities. By separate prospectus, the form of which is included in the
Registration Statement of which this Prospectus is a part, the Company may offer
from time to time senior debt securities and/or subordinated debt securities
each of which will be direct, unsecured obligations of the Company. The
aggregate initial public offering price of the securities to be offered by this
Prospectus and such other prospectus shall not exceed $500,000,000.
 
    The Offered Securities may be sold (i) directly to purchasers, (ii) through
agents designated from time to time, (iii) to dealers or (iv) through
underwriters or a group of underwriters. If agents of the Company and/or any PWG
Trust or underwriters are involved in the sale of the Offered Securities, their
names will be set forth in the applicable Prospectus Supplement. If agents of
the Company and/or any PWG Trust, or underwriters or dealers are involved in the
sale of the Offered Securities, descriptions of their compensation and
indemnification arrangements and the net proceeds to the Company and/or any PWG
Trust will be set forth in the applicable Prospectus Supplement.

                             AVAILABLE INFORMATION
 
     The Company is subject to the informational requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
therewith files reports, proxy statements and other information with the
Securities and Exchange Commission (the "Commission"). The registration
statement of which this Prospectus forms a part, as well as reports, proxy
statements and other information filed by the Company, may be inspected and
copied at the public reference facilities maintained by the Commission at 450
Fifth Street, N.W., Washington, D.C. 20549; 7 World Trade Center, New York, New
York 10048; and Citicorp Center, 500 West Madison Street, Suite 1400, Chicago,
Illinois 60661. Copies of such material can be obtained at prescribed rates from
the Public Reference Section of the Commission at 450 Fifth Street, N.W.,
Washington, D.C. 20549. Such material may also be accessed electronically by
means of the Commission's home page on the Internet at http://www.sec.gov. In
addition, reports, proxy statements and other information concerning the Company
can also be inspected at the offices of the New York Stock Exchange, Inc. (the
"NYSE"), 20 Broad Street, New York, New York and the Pacific Stock Exchange, 301
Pine Street, San Francisco, California.
 
     This Prospectus constitutes a part of the Registration Statement on Form
S-3 (together with all amendments and exhibits thereto, the "Registration
Statement") filed with the Commission under the Securities Act of 1933 (the
"Securities Act") with respect to the Offered Securities. This Prospectus does
not contain all of the information set forth in such Registration Statement,
certain parts of which are omitted in accordance with the rules and regulations
of the Commission. Reference is made to such Registration Statement and to the
exhibits relating thereto for further information with respect to the Company,
the PWG Trusts and the Offered Securities. Any statements contained herein
concerning the provisions of any document filed as an exhibit to the
Registration Statement or otherwise filed with the Commission or incorporated by
reference herein are not necessarily complete, and in each instance reference is
made to the copy of such document so filed for a more complete description of
the matter involved. Each such statement is qualified in its entirety by such
reference.
 
   
     No separate financial statements of any of the PWG Trusts have been
included or incorporated by reference herein. The Company and the PWG Trusts do
not consider that such financial statements would be material to holders of the
Preferred Securities because (i) all the voting securities of each PWG Trust
will be owned, directly or indirectly, by the Company, a reporting company under
the Exchange Act, (ii) each PWG Trust is a newly formed special purpose entity,
has no operating history, has no independent operations and is not engaged in,
and does not propose to engage in, any activity other than issuing Trust
Securities (as defined herein) representing undivided beneficial interests in
the assets of such PWG Trust and investing the proceeds thereof in Junior
Subordinated Debt Securities issued by the Company and (iii) the obligations of
each PWG Trust under the Preferred Securities of PWG Trust will be fully and
unconditionally guaranteed by the Company as described herein. See "The PWG
Trusts," "Description of the Preferred Securities," "Description of the
Preferred Securities Guarantees" and "Description of the Junior Subordinated
Debt Securities." The PWG Trusts are business trusts formed under the laws of
the State of Delaware. The Company, as of the date of this Prospectus,
beneficially owns all the beneficial interests in each PWG Trust. Each holder of
Preferred Securities of a PWG Trust will be furnished annually with unaudited
financial statements of such Trust as soon as available after the end of the
Trust's fiscal year.

                                 THE PWG TRUSTS
 
   
     Each of PWG Capital Trust I, PWG Capital Trust II, PWG Capital Trust III
and PWG Capital Trust IV is a business trust formed on October 7, 1996 under the
Delaware Business Trust Act (the "Business Trust Act") pursuant to a separate
declaration of trust among the Trustees (as defined herein) of such PWG Trust
and the Company and the filing of a certificate of trust with the Secretary of
State of the State of Delaware. Such declaration will be amended and restated in
its entirety (as so amended and restated, the "Declaration") substantially in
the form filed as an exhibit to the Registration Statement of which this
Prospectus forms a part, as of the date the Preferred Securities of such PWG
Trust are initially issued. Each Declaration will be qualified under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act").
    
 
     This description summarizes the material terms of the Declarations and is
qualified in its entirety by reference to the form of Declaration, which has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part, and the Trust Indenture Act.
 
TRUST SECURITIES
 
     Upon issuance of any Preferred Securities by a PWG Trust, the holders
thereof will own all the issued and outstanding Preferred Securities of such PWG
Trust. The Company will acquire securities representing common undivided
beneficial interests in the assets of each PWG Trust (the "Common Securities"
and, together with the Preferred Securities, the "Trust Securities") in an
amount equal to at least 3% of the total capital of such PWG Trust and will own,
directly or indirectly, all the issued and outstanding Common Securities of each
PWG Trust. The Preferred Securities and the Common Securities will rank pari
passu with each other and will have equivalent terms; provided that (i) if a
Declaration Event of Default (as defined herein) under the Declaration of a PWG
Trust occurs and is continuing, the holders of Preferred Securities of such PWG
Trust will have a priority over holders of the Common Securities of such PWG
Trust with respect to payments in respect of distributions and payments upon
liquidation, redemption and maturity and (ii) holders of Common Securities have
the exclusive right (subject to the terms of the Declaration) to appoint, remove
or replace the Trustees and to increase or decrease the number of Trustees. Each
PWG Trust exists for the purpose of (a) issuing its Preferred Securities, (b)
issuing its Common Securities to the Company, (c) investing the gross proceeds
from the sale of the Trust Securities in Junior Subordinated Debt Securities of
the Company and (d) engaging in only such other activities as are necessary,
convenient or incidental thereto. The rights of the holders of the Preferred
Securities, including economic rights, rights to information and voting rights,
are set forth in the applicable Declaration, the Business Trust Act and the
Trust Indenture Act.
 
POWERS AND DUTIES OF TRUSTEES
 
     The number of trustees (the "Trustees") of each PWG Trust shall initially
be five. Three of such Trustees (the "Regular Trustees") are individuals who are
employees or officers of the Company. The fourth such trustee will be The Chase
Manhattan Bank, which is unaffiliated with the Company and which will serve as
the property trustee (the "Property Trustee") and act as the indenture trustee
for purposes of the Trust Indenture Act. The fifth such trustee is Chase
Manhattan Bank Delaware, an affiliate of The Chase Manhattan Bank that has its
principal place of business in the State of Delaware (the "Delaware Trustee").
Pursuant to each Declaration, legal title to the Junior Subordinated Debt
Securities purchased by a PWG Trust will be held by the Property Trustee for the
benefit of the holders of the Trust Securities of such PWG
 
                                        5
<PAGE>   43
 
   
Trust, and the Property Trustee will have the power to exercise all rights,
powers and privileges under the Indenture (as defined under "Description of the
Junior Subordinated Debt Securities") with respect to such Junior Subordinated
Debt Securities. In addition, the Property Trustee will maintain exclusive
control of a segregated non-interest-bearing bank account (the "Property
Account") to hold all payments in respect of the Junior Subordinated Debt
Securities purchased by a PWG Trust for the benefit of the holders of Trust
Securities. The Property Trustee will promptly make distributions to the holders
of the Trust Securities of a PWG Trust out of funds from the Property Account of
such PWG Trust. The Preferred Securities Guarantees are separately qualified
under the Trust Indenture Act and will be held by The Chase Manhattan Bank,
acting in its capacity as indenture trustee with respect thereto, for the
benefit of the holders of the applicable Preferred Securities. As used in this
Prospectus and any accompanying Prospectus Supplement, the term "Property
Trustee" with respect to a PWG Trust refers to The Chase Manhattan Bank acting
either in its capacity as a Trustee under the relevant Declaration and the
holder of legal title to the Junior Subordinated Debt Securities purchased by
such Trust or in its capacity as indenture trustee under, and the holder of, the
applicable Preferred Securities Guarantee, as the context may require. The
Company, as the direct or indirect owner of all the Common Securities of each
PWG Trust, will have the exclusive right (subject to the terms of the related
Declaration) to appoint, remove or replace Trustees and to increase or decrease
the number of Trustees, provided that the number of Trustees shall be at least
five (unless the Trustee that acts as the Property Trustee also acts as the
Delaware Trustee, in which case the number of Trustees shall be at least three)
and the majority of Trustees shall be Regular Trustees. The term of a PWG Trust
will be set forth in the applicable Prospectus Supplement, but may terminate
earlier as provided in the Declaration of such PWG Trust.
    
 
     The duties and obligations of the Trustees of a PWG Trust shall be governed
by the Declaration of such PWG Trust. Under its Declaration, each PWG Trust
shall not, and the Trustees of such PWG Trust shall cause such PWG Trust not to,
engage in any activity other than in connection with the purposes of such PWG
Trust or other than as required or authorized by such Declaration. In
particular, each PWG Trust shall not, and the Trustees of such PWG Trust shall
cause such PWG Trust not to, (a) invest any proceeds received by such PWG Trust
from holding the Junior Subordinated Debt Securities purchased by such PWG
Trust, but shall promptly distribute from the Property Account of such PWG Trust
all such proceeds to holders of its Trust Securities pursuant to the terms of
the Declaration of such PWG Trust and of such Trust Securities; (b) acquire any
assets other than as expressly provided in such Declaration; (c) possess Trust
property for other than a Trust purpose; (d) make any loans, other than loans
represented by such Junior Subordinated Debt Securities; (e) possess any power
or otherwise act in such a way as to vary the assets of such PWG Trust or the
terms of its Trust Securities in any way whatsoever; (f) issue any securities or
other evidences of beneficial ownership of, or beneficial interests in, such PWG
Trust other than its Trust Securities; (g) incur any indebtedness for borrowed
money or (h)(i) direct the time, method and place of exercising any trust or
power conferred upon the Indenture Trustee (as defined under "Description of the
Junior Subordinated Debt Securities") with respect to the Junior Subordinated
Debt Securities deposited in such PWG Trust as trust assets or upon the Property
Trustee of such PWG Trust with respect to its Preferred Securities, (ii) waive
any past default that is waivable under the applicable Indenture or such
Declaration, (iii) exercise any right to rescind or annul any declaration that
the principal of all of the Junior Subordinated Debt Securities deposited in
such PWG Trust as trust assets shall be due and payable or (iv) consent to any
amendment, modification or termination of such Indenture or such Junior
Subordinated Debt Securities or such Declaration, in each case where such
consent shall be required, unless in the case of this clause (h) the Property
Trustee shall have received an unqualified opinion of nationally recognized
independent tax counsel recognized as expert in such matters to the effect that
such action will not cause such PWG Trust to be classified for United States
Federal income tax purposes as an association taxable as a corporation or a
partnership and that such PWG Trust will continue to be classified as a grantor
trust for United States Federal income tax purposes.
 
BOOKS AND RECORDS
 
     The books and records of each PWG Trust will be maintained at the principal
office of such PWG Trust and will be open for inspection by a holder of
Preferred Securities of such PWG Trust or such holder's representative for any
purpose reasonably related to such holder's interest in such PWG Trust during
normal
 
                                        6
<PAGE>   44
 
business hours. Each holder of Preferred Securities will be furnished annually
with unaudited financial statements of the applicable PWG Trust as soon as
available after the end of such PWG Trust's fiscal year.
 
VOTING
 
     Except as provided under the Business Trust Act, the applicable Declaration
and the Trust Indenture Act, holders of Preferred Securities will have no voting
rights.
 
THE PROPERTY TRUSTEE
 
     The Property Trustee, for the benefit of the holders of the Trust
Securities of a PWG Trust, is authorized under each Declaration to exercise all
rights under the Indenture with respect to the Junior Subordinated Debt
Securities deposited in such PWG Trust as trust assets, including its rights as
the holder of such Junior Subordinated Debt Securities to enforce the Company's
obligations under such Junior Subordinated Debt Securities upon the occurrence
of an Indenture Event of Default. The Property Trustee is also authorized to
enforce the rights of holders of Preferred Securities of a PWG Trust under the
related Preferred Securities Guarantee. If any PWG Trust's failure to make
distributions on the Preferred Securities of such PWG Trust is a consequence of
the Company's exercise of any right under the terms of the Junior Subordinated
Debt Securities deposited in such PWG Trust as trust assets to extend the
interest payment period for such Junior Subordinated Debt Securities, the
Property Trustee will have no right to enforce the payment of distributions on
such Preferred Securities until a Declaration Event of Default shall have
occurred. Holders of at least a majority in liquidation amount of the Preferred
Securities of a PWG Trust will have the right to direct the Property Trustee for
such PWG Trust with respect to certain matters under the Declaration for such
PWG Trust and the related Preferred Securities Guarantee. If the Property
Trustee fails to enforce its rights under the Indenture or fails to enforce the
applicable Preferred Securities Guarantee, to the extent permitted by applicable
law, any holder of Preferred Securities of a PWG Trust may institute a legal
proceeding against the Company to enforce such rights or such Preferred
Securities Guarantee, as the case may be.
 
DISTRIBUTIONS
 
   
     Pursuant to each Declaration, distributions on the Preferred Securities of
a PWG Trust must be paid on the dates payable to the extent that the Property
Trustee has cash on hand in the Property Account of such PWG Trust to permit
such payment. The funds available for distribution to the holders of the
Preferred Securities of a PWG Trust will be limited to payments received by the
Property Trustee in respect of the Junior Subordinated Debt Securities that are
deposited in such PWG Trust as trust assets. If the Company does not make
interest payments on the Junior Subordinated Debt Securities deposited in a PWG
Trust as trust assets, the Property Trustee will not make distributions on the
Preferred Securities of such PWG Trust. Under the Declaration, if and to the
extent the Company does make interest payments on the Junior Subordinated Debt
Securities deposited in a PWG Trust as trust assets, the Property Trustee is
obligated to make distributions on the Trust Securities of such PWG Trust on a
pro rata basis (as defined below). The payment of distributions on the Preferred
Securities of a PWG Trust is guaranteed by the Company on a subordinated basis
as and to the extent set forth under "Description of the Preferred Securities
Guarantees." A Preferred Securities Guarantee is a full and unconditional
guarantee from the time of issuance of the Preferred Securities of a PWG Trust,
but such Preferred Securities Guarantee covers distributions and other payments
on such Preferred Securities only if and to the extent that the Company has made
a payment to the Property Trustee of interest or principal on the Junior
Subordinated Debt Securities deposited in such PWG Trust as trust assets. As
used in this Prospectus, the term "pro rata basis" shall mean pro rata to each
holder of Trust Securities of a PWG Trust according to the aggregate liquidation
amount of the Trust Securities of such PWG Trust held by the relevant holder in
relation to the aggregate liquidation amount of all Trust Securities of such PWG
Trust outstanding unless, in relation to a payment, a Declaration Event of
Default under the Declaration has occurred and is continuing, in which case any
funds available to make such payment shall be paid first to each holder of the
Preferred Securities of such PWG Trust pro rata according to the aggregate
liquidation amount of the Preferred Securities held by the relevant holder in
relation to the aggregate liquidation amount of all the Preferred Securities of
such PWG Trust outstanding, and only after
    
 
                                        7
<PAGE>   45
 
satisfaction of all amounts owed to the holders of such Preferred Securities, to
each holder of Common Securities of such PWG Trust pro rata according to the
aggregate liquidation amount of such Common Securities held by the relevant
holder in relation to the aggregate liquidation amount of all Common Securities
of such PWG Trust outstanding.
 
EVENTS OF DEFAULT
 
     If an Indenture Event of Default occurs and is continuing with respect to
Junior Subordinated Debt Securities deposited in a PWG Trust as trust assets, an
Event of Default under the Declaration (a "Declaration Event of Default") of
such PWG Trust will occur and be continuing with respect to any outstanding
Trust Securities of such PWG Trust. In such event, each Declaration provides
that the holders of Common Securities of the applicable PWG Trust will be deemed
to have waived any such Declaration Event of Default with respect to such Common
Securities until all Declaration Events of Default with respect to the Preferred
Securities of such PWG Trust have been cured or waived. Until all such
Declaration Events of Default with respect to the Preferred Securities of such
PWG Trust have been so cured or waived, the Property Trustee will be deemed to
be acting solely on behalf of the holders of the Preferred Securities of such
PWG Trust and only the holders of such Preferred Securities will have the right
to direct the Property Trustee with respect to certain matters under such
Declaration and consequently under the Indenture. In the event that any
Declaration Event of Default with respect to the Preferred Securities of a PWG
Trust is waived by the holders of the Preferred Securities of such PWG Trust as
provided in the Declaration of such PWG Trust, the holders of Common Securities
of such PWG Trust pursuant to such Declaration have agreed that such waiver also
constitutes a waiver of such Declaration Event of Default with respect to such
Common Securities for all purposes under such Declaration without any further
act, vote or consent of the holders of such Common Securities.
 
RECORD HOLDERS
 
     Each Declaration provides that the Trustees of the applicable PWG Trust may
treat the person in whose name a certificate representing Preferred Securities
of such PWG Trust is registered on the books and records of such PWG Trust as
the sole holder thereof and of the Preferred Securities represented thereby for
purposes of receiving distributions and for all other purposes and, accordingly,
shall not be bound to recognize any equitable or other claim to or interest in
such certificate or in the Preferred Securities represented thereby on the part
of any person, whether or not such PWG Trust shall have actual or other notice
thereof. Preferred Securities will be issued in fully registered form. Unless
otherwise specified in a Prospectus Supplement, Preferred Securities will be
represented by a global certificate registered on the books and records of such
PWG Trust in the name of a depositary (the "Depositary") named in an
accompanying Prospectus Supplement or its nominee. Under each Declaration:
 
          (i) the applicable PWG Trust and the Trustees thereof shall be
     entitled to deal with the Depositary (or any successor depositary) for all
     purposes, including the payment of distributions and receiving approvals,
     votes or consents under such Declaration and, except as set forth in such
     Declaration with respect to the Property Trustee, shall have no obligation
     to persons owning a beneficial interest in Preferred Securities of such PWG
     Trust ("Preferred Security Beneficial Owners") registered in the name of
     and held by the Depositary or its nominee; and
 
          (ii) the rights of Preferred Security Beneficial Owners shall be
     exercised only through the Depositary (or any successor depositary) and
     shall be limited to those established by law and agreements between such
     Preferred Security Beneficial Owners and the Depositary and/or its
     participants. With respect to Preferred Securities registered in the name
     of and held by the Depositary or its nominee, all notices and other
     communications required under such Declaration shall be given to, and all
     distributions on such Preferred Securities shall be given or made to, the
     Depositary (or its successor).
 
The specific terms of the depositary arrangement with respect to the Preferred
Securities of a PWG Trust will be disclosed in the applicable Prospectus
Supplement.

DEBTS AND OBLIGATIONS
 
     In each Declaration, the Company has agreed to pay for all debts and
obligations (other than with respect to the Trust Securities of the applicable
PWG Trust) and all costs and expenses of such PWG Trust, including the fees and
expenses of its Trustees and any taxes and all costs and expenses with respect
thereto, to which such PWG Trust may become subject, except for United States
withholding taxes. The foregoing obligations of the Company under each
Declaration are for the benefit of, and shall be enforceable by, any person to
whom any such debts, obligations, costs, expenses and taxes are owed (a
"Creditor") whether or not such Creditor has received notice thereof. Any such
Creditor may enforce such obligations of the Company directly against the
Company and the Company has irrevocably waived any right or remedy to require
that any such Creditor take any action against any PWG Trust or any other person
before proceeding against the Company. The Company has agreed in each
Declaration to execute such additional agreements as may be necessary or
desirable in order to give full effect to the foregoing.
 
     The business address of each PWG Trust is c/o PaineWebber Group Inc., 1285
Avenue of the Americas, New York, NY 10019, telephone number (212) 713-2000.
 
                    DESCRIPTION OF THE PREFERRED SECURITIES
 
     Each PWG Trust may issue, from time to time, only one series of Preferred
Securities having terms described in the Prospectus Supplement relating thereto.
The Declaration of each PWG Trust authorizes the Regular Trustees of such PWG
Trust to issue on behalf of such PWG Trust one series of Preferred Securities.
Each Declaration will be qualified as an indenture under the Trust Indenture
Act. The Preferred Securities will have such terms, including distributions,
redemption, voting, liquidation rights and such other preferred, deferred or
other special rights or such restrictions as shall be set forth in the related
Declaration or made part of such Declaration by the Trust Indenture Act.
Reference is made to the Prospectus Supplement relating to the Preferred
Securities of a PWG Trust for specific terms, including (i) the specific
designation of such Preferred Securities, (ii) the number of Preferred
Securities issued by such PWG Trust, (iii) the annual distribution rate (or
method of calculation thereof) for Preferred Securities issued by such PWG
Trust, the date or dates upon which such distributions shall be payable and the
record date or dates for the payment of such distributions, (iv) whether
distributions on Preferred Securities issued by such PWG Trust shall be
cumulative, and, in the case of Preferred Securities having such cumulative
distribution rights, the date or dates or method of determining the date or
dates from which distributions on Preferred Securities issued by such PWG Trust
shall be cumulative, (v) the amount or amounts which shall be paid out of the
assets of such PWG Trust to the holders of Preferred Securities of such PWG
Trust upon voluntary or involuntary liquidation, dissolution, winding-up or
termination of such PWG Trust, (vi) the obligation or right, if any, of such PWG
Trust to purchase or redeem Preferred Securities issued by such PWG Trust and
the price or prices at which, the period or periods within which and the terms
and conditions upon which Preferred Securities issued by such PWG Trust shall or
may be purchased or redeemed, in whole or in part, pursuant to such obligation
or right, (vii) the voting rights, if any, of Preferred Securities issued by
such PWG Trust in addition to those required by law, including the number of
votes per Preferred Security and any requirement for the approval by the holders
of Preferred Securities, or of Preferred Securities issued by one or more PWG
Trusts, or of both, as a condition to specified actions or amendments to the
Declaration of such PWG Trust, (viii) terms for any conversion or exchange into
other securities and (ix) any other relevant rights, preferences, privileges,
limitations or restrictions of Preferred Securities issued by such PWG Trust
consistent with the Declaration of such PWG Trust or with applicable law. All
Preferred Securities offered hereby will be guaranteed by the Company as and to
the extent set forth below under "Description of the Preferred Securities
Guarantees." Certain United States Federal income tax considerations applicable
to any offering of Preferred Securities will be described in the Prospectus
Supplement relating thereto.
 
     In connection with the issuance of Preferred Securities, each PWG Trust
will issue one series of Common Securities. The Declaration of each PWG Trust
authorizes the Regular Trustees of such PWG Trust to issue on behalf of such PWG
Trust one series of Common Securities having such terms including distributions,
redemption, voting, liquidation rights or such restrictions as shall be set
forth therein. The terms
 
                                        9
<PAGE>   47
 
   
of the Common Securities issued by a PWG Trust will be substantially identical
to the terms of the Preferred Securities issued by such PWG Trust and the Common
Securities will rank pari passu and payments will be made thereon on a pro rata
basis with the Preferred Securities except that, if a Declaration Event of
Default occurs and is continuing, the rights of the holders of such Common
Securities to payment in respect of distributions and payments upon liquidation,
redemption and maturity will be subordinated to the rights of the holders of
such Preferred Securities. Except in certain limited circumstances, the Common
Securities issued by a PWG Trust will also carry the right to vote and to
appoint, remove or replace any of the Trustees of such PWG Trust. All the Common
Securities of a PWG Trust will be directly or indirectly owned by the Company.
    
 
   
     If an Event of Default with respect to the Declaration of any PWG Trust
occurs and is continuing, then the holders of Preferred Securities of such PWG
Trust would rely on the enforcement by the Property Trustee of its rights as a
holder of the Junior Subordinated Debt Securities deposited in such PWG Trust
against the Company. In addition, the holders of a majority in liquidation
amount of such Preferred Securities will have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee or to direct the exercise of any trust or power conferred upon
the Property Trustee under such Declaration, including the right to direct the
Property Trustee to exercise the remedies available to it as a holder of such
Junior Subordinated Debt Securities. If the Property Trustee fails to enforce
its rights under such Junior Subordinated Debt Securities deposited in such PWG
Trust, any holder of such Preferred Securities may, to the extent permitted by
applicable law, after a period of 30 days has elapsed from such holder's written
request, institute a legal proceeding against the Company to enforce the
Property Trustee's rights under such Junior Subordinated Debt Securities without
first instituting any legal proceeding against the Property Trustee or any other
person or entity. If an Event of Default with respect to the Declaration of any
PWG Trust occurs and is continuing and such event is attributable to the failure
of the Company to pay interest or principal on the Junior Subordinated Debt
Securities on the date such interest or principal is otherwise payable (or in
the case of redemption, on the redemption date), then a holder of Preferred
Securities of such PWG Trust may also directly institute a proceeding for
enforcement of payment to such holder of the principal of or interest on such
Junior Subordinated Debt Securities having a principal amount equal to the
aggregate liquidation amount of such Preferred Securities held by such holder (a
"Direct Action") on or after the respective due date specified in such Junior
Subordinated Debt Securities without first (i) directing the Property Trustee to
enforce the terms of such Junior Subordinated Debt Securities or (ii)
instituting a legal proceeding against the Company to enforce the Property
Trustee's rights under such Junior Subordinated Debt Securities. In connection
with such Direct Action, the Company will be subrogated to the rights of such
holder of such Preferred Securities under such Declaration to the extent of any
payment made by the Company to such holder of such Preferred Securities in such
Direct Action. The holders of Preferred Securities of a PWG Trust will not be
able to exercise directly any other remedy available to the holders of the
Junior Subordinated Debt Securities unless the Property Trustee first fails to
do so.
    
 
               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEES
 
   
     Set forth below is a summary of information concerning the Preferred
Securities Guarantees that will be executed and delivered by the Company for the
benefit of the holders from time to time of Preferred Securities of a PWG Trust.
Each Preferred Security Guarantee will be separately qualified under the Trust
Indenture Act and will be held by The Chase Manhattan Bank, acting in its
capacity as indenture trustee with respect thereto (the "Guarantee Trustee"),
for the benefit of holders of the Preferred Securities of the applicable PWG
Trust. The terms of each Preferred Securities Guarantee will be those set forth
in such Preferred Securities Guarantee and those made part of such Preferred
Securities Guarantee by the Trust Indenture Act. This description summarizes the
material terms of the Preferred Securities Guarantees and is qualified in its
entirety by reference to the form of Preferred Securities Guarantee, which is
filed as an exhibit to the Registration Statement of which this Prospectus forms
a part, and the Trust Indenture Act. Section references used herein are
references to the provisions of the form of Preferred Securities Guarantee.

GENERAL
 
   
     Pursuant to each Preferred Securities Guarantee, the Company will
irrevocably and unconditionally agree, to the extent set forth therein, to pay
in full, to the holders of the Preferred Securities issued by the applicable PWG
Trust, the Guarantee Payments (as defined herein), to the extent not paid by
such PWG Trust, regardless of any defense, right of set-off or counterclaim that
such PWG Trust may have or assert. The following distributions and other
payments with respect to Preferred Securities issued by a PWG Trust to the
extent not made or paid by such PWG Trust (the "Guarantee Payments"), will be
subject to the Preferred Securities Guarantee (without duplication): (i) any
accrued and unpaid distributions on such Preferred Securities, but only if and
to the extent that in each case the Company has made a payment to the Property
Trustee of interest on the Junior Subordinated Debt Securities, (ii) the
redemption price, including all accrued and unpaid distributions to the date of
redemption, with respect to any Preferred Securities called for redemption by
such PWG Trust, but only if and to the extent that in each case the Company has
made a payment to the Property Trustee of interest or principal on the Junior
Subordinated Debt Securities deposited in such PWG Trust as trust assets, and
(iii) upon a voluntary or involuntary liquidation, dissolution, winding-up or
termination of such PWG Trust (other than in connection with the distribution of
such Junior Subordinated Debt Securities to the holders of such Preferred
Securities or the redemption of all such Preferred Securities upon the maturity
or redemption of such Junior Subordinated Debt Securities) the lesser of (a) the
aggregate of the liquidation amount and all accrued and unpaid distributions on
such Preferred Securities to the date of payment, to the extent such PWG Trust
has funds available therefor, and (b) the amount of assets of such PWG Trust
remaining available for distribution to holders of such Preferred Securities
upon liquidation of such PWG Trust. The Company's obligation to make a Guarantee
Payment may be satisfied by direct payment of the required amounts by the
Company to the holders of the applicable Preferred Securities or by causing the
applicable PWG Trust to pay such amounts to such holders.
    
 
     The Preferred Securities Guarantee is a full and unconditional guarantee
from the time of issuance of the applicable Preferred Securities, but the
Preferred Securities Guarantee covers distributions and other payments on such
Preferred Securities only if and to the extent that the Company has made a
payment to the Property Trustee of interest or principal on the Junior
Subordinated Debt Securities deposited in the applicable PWG Trust as trust
assets. If the Company does not make interest or principal payments on the
Junior Subordinated Debt Securities deposited in the applicable PWG Trust as
trust assets, the Property Trust will not make distributions on the Preferred
Securities of such PWG Trust and the PWG Trust will not have funds available
therefor.
 
     The Company's obligations under the Declaration for each PWG Trust, the
Preferred Securities Guarantee issued with respect to Preferred Securities
issued by such PWG Trust, the Junior Subordinated Debt Securities purchased by
such PWG Trust and the Indenture in the aggregate will provide a full and
unconditional guarantee on a subordinated basis by the Company of payments due
on the Preferred Securities issued by such PWG Trust.
 
CERTAIN COVENANTS OF THE COMPANY
 
   
     In each Preferred Securities Guarantee, the Company will covenant that, so
long as any Preferred Securities issued by the applicable PWG Trust remain
outstanding, the Company will not declare or pay any dividends on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred stock or make any guarantee payment with
respect thereto, if at such time (i) the Company shall be in default with
respect to its Guarantee Payments or other payment obligations under such
Preferred Securities Guarantee, (ii) there shall have occurred any Event of
Default under the related Declaration or (iii) in the event that Junior
Subordinated Debt Securities are issued to the applicable PWG Trust in
connection with the issuance of Trust Securities by such PWG Trust, the Company
shall have given notice of its election to defer payments of interest on such
Junior Subordinated Debt Securities by extending the interest payment period as
provided in the terms of the Junior Subordinated Debt Securities and such
period, or any extension thereof, is continuing; provided, however, that the
foregoing restrictions shall not apply to (i) dividends, redemptions, purchases,
acquisitions, distributions or payments made by the Company by way of issuance
of shares of its capital stock, (ii) payments of accrued dividends by the
Company upon the
    
 
                                       11
<PAGE>   49
 
   
redemption, exchange or conversion of any preferred stock of the Company as may
be outstanding from time to time in accordance with the terms of such preferred
stock or (iii) cash payments made by the Company in lieu of delivering
fractional shares upon the redemption, exchange or conversion of any preferred
stock of the Company as may be outstanding from time to time in accordance with
the terms of such preferred stock. In addition, so long as any Preferred
Securities of a PWG Trust remain outstanding, the Company has agreed (i) to
remain the sole direct or indirect owner of all the outstanding Common
Securities issued by such PWG Trust and not to cause or permit such Common
Securities to be transferred except to the extent permitted by the Declaration
of such PWG Trust, provided that any permitted successor of the Company under
the Indenture may succeed to the Company's ownership of such Common Securities,
and (ii) to use reasonable efforts to cause such PWG Trust to continue to be
treated as a grantor trust for United States Federal income tax purposes, except
in connection with a distribution of Junior Subordinated Debt Securities.
(Section 6.01)
    
 
AMENDMENTS AND ASSIGNMENT
 
   
     Except with respect to any changes that do not adversely affect the rights
of holders of the applicable Preferred Securities (in which case no consent will
be required), each Preferred Securities Guarantee may be amended only with the
prior approval of the holders of not less than 66 2/3% in liquidation amount of
the outstanding Preferred Securities issued by the applicable PWG Trust. The
manner of obtaining any such approval of holders of such Preferred Securities
will be set forth in an accompanying Prospectus Supplement. (Section 9.02) All
guarantees and agreements contained in a Preferred Securities Guarantee shall
bind the successors, assignees, receivers, trustees and representatives of the
Company and shall inure to the benefit of the holders of the Preferred
Securities of the applicable PWG Trust then outstanding. Except in connection
with a consolidation, merger, conveyance, transfer or lease of assets involving
the Company that is permitted under the Indenture, the Company may not assign
its obligations under any Preferred Securities Guarantee. (Section 9.01)
    
 
TERMINATION OF THE PREFERRED SECURITIES GUARANTEES
 
   
     Each Preferred Securities Guarantee will terminate and be of no further
force and effect as to the Preferred Securities issued by the applicable PWG
Trust upon full payment of the redemption price of all Preferred Securities of
such PWG Trust, or upon distribution of the Junior Subordinated Debt Securities
to the holders of the Preferred Securities of such PWG Trust in exchange for all
the Preferred Securities issued by such PWG Trust, or upon full payment of the
amounts payable upon liquidation of such PWG Trust. Notwithstanding the
foregoing, each Preferred Securities Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any holder of Preferred
Securities issued by the applicable PWG Trust must restore payment of any sums
paid under such Preferred Securities or such Preferred Securities Guarantee.
(Section 7.01)
    
 
STATUS OF THE PREFERRED SECURITIES GUARANTEES
 
   
     The Company's obligations under each Preferred Securities Guarantee to make
the Guarantee Payments will constitute an unsecured obligation of the Company
and will rank (i) subordinate and junior in right of payment to all other
indebtedness, liabilities and obligations of the Company and any guarantees,
endorsements or other contingent obligations of the Company in respect of such
indebtedness, liabilities or obligations, including the Junior Subordinated Debt
Securities, except those made pari passu or subordinate by their terms, and (ii)
senior to all capital stock now or hereafter issued by the Company and to any
guarantee now or hereafter entered into by the Company in respect of any of its
capital stock. The Company's obligations under each Preferred Securities
Guarantee will rank pari passu with each other Preferred Securities Guarantee.
(Section 6.02) Because the Company is a holding company, the Company's
obligations under each Preferred Securities Guarantee are also effectively
subordinated to all existing and future liabilities, including trade payables,
of the Company's subsidiaries, except to the extent that the Company is a
creditor of the subsidiaries recognized as such. Each Declaration provides that
each holder of Preferred Securities issued by the applicable PWG Trust, by
acceptance thereof, agrees to the subordination provisions and other terms of
the related Preferred Securities Guarantee.
    
 
                                       12
<PAGE>   50
 
   
     Each Preferred Securities Guarantee will constitute a guarantee of payment
and not of collection (that is, the guaranteed party may institute a legal
proceeding directly against the Company to enforce its rights under such
Preferred Securities Guarantee without first instituting a legal proceeding
against any other person or entity). Each Preferred Securities Guarantee will be
deposited with the Guarantee Trustee, to be held for the benefit of the holders
of the Preferred Securities issued by the applicable PWG Trust. The Guarantee
Trustee shall enforce such Preferred Securities Guarantee on behalf of the
holders of such Preferred Securities. The holders of not less than a majority in
aggregate liquidation amount of the Preferred Securities issued by the
applicable PWG Trust have the right to direct the time, method and place of
conducting any proceeding for any remedy available in respect of the related
Preferred Securities Guarantee, including the giving of directions to the
Guarantee Trustee. If the Guarantee Trustee fails to enforce a Preferred
Securities Guarantee as above provided, any holder of Preferred Securities
issued by the applicable PWG Trust may institute a legal proceeding directly
against the Company to enforce its rights under such Preferred Securities
Guarantee, without first instituting a legal proceeding against the applicable
PWG Trust, or any other person or entity. Notwithstanding the foregoing, if the
Company has failed to make a Guarantee Payment, a holder of Preferred Securities
may directly institute a proceeding against the Company for enforcement of such
holder's right to receive payment under the Preferred Securities Guarantee. The
Company waives any right or remedy to require that any action be brought first
against a PWG Trust or any other person or entity before proceeding directly
against the Company.
    
 
MISCELLANEOUS
 
   
     The Company will be required to provide annually to the Guarantee Trustee a
statement as to the performance by the Company of certain of its obligations
under each Preferred Securities Guarantee and as to any default in such
performance. The Company is required to file annually with the Guarantee Trustee
an officer's certificate as to the Company's compliance with all conditions to
be complied with by it under each Preferred Securities Guarantee. (Section 2.04)
    
 
   
     The Guarantee Trustee, prior to the occurrence of a default, undertakes to
perform only such duties as are specifically set forth in the applicable
Preferred Securities Guarantee and, after default with respect to a Preferred
Securities Guarantee, shall exercise the same degree of care as a prudent
individual would exercise under the circumstances in the conduct of his or her
own affairs. Subject to such provision, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by a Preferred Securities
Guarantee at the request of any holder of Preferred Securities unless it is
offered reasonable security and indemnity against the costs, expenses and
liabilities that might be incurred thereby. (Section 3.02)
    
 
GOVERNING LAW
 
   
     The Preferred Securities Guarantees will be governed by, and construed in
accordance with, the laws of the State of New York. (Section 9.06)
    
 
             DESCRIPTION OF THE JUNIOR SUBORDINATED DEBT SECURITIES
 
     Junior Subordinated Debt Securities may be issued from time to time in one
or more series under an Indenture (the "Indenture") between the Company and The
Chase Manhattan Bank, as trustee (the "Indenture Trustee"). The Indenture has
been filed as an exhibit to the Registration Statement of which this Prospectus
forms a part. The following description summarizes the material terms of the
Indenture, 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. Section references used herein are references
to provisions of the Indenture.
 
GENERAL
 
     The Junior Subordinated Debt Securities will be unsecured, junior
subordinated obligations of the Company. The Indenture does not limit the amount
of additional indebtedness the Company or any of its subsidiaries may incur.
Since the Company is a holding company, the Company's rights and the rights of
its
 
                                       13
<PAGE>   51
 
creditors, including the holders of Junior Subordinated Debt 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 Company may itself be a creditor with
recognized claims against the subsidiary.
 
     The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that Junior Subordinated Debt
Securities may be issued thereunder from time to time in one or more series. The
Junior Subordinated Debt Securities are issuable in one or more series pursuant
to an indenture supplemental to the Indenture.
 
     In the event Junior Subordinated Debt Securities are issued to a PWG Trust
or a Trustee of such PWG Trust in connection with the issuance of Trust
Securities by such PWG Trust, such Junior Subordinated Debt Securities
subsequently may be distributed pro rata to the holders of such Trust Securities
in connection with the dissolution of such PWG Trust upon the occurrence of
certain events described in the applicable Prospectus Supplement. Only one
series of Junior Subordinated Debt Securities will be issued to a PWG Trust or a
Trustee of such PWG Trust in connection with the issuance of Trust Securities by
such PWG Trust.
 
   
     Reference is made to the Prospectus Supplement which will accompany this
Prospectus for the following terms of the series of Junior Subordinated Debt
Securities being offered thereby (to the extent such terms are applicable to the
Junior Subordinated Debt Securities): (i) the specific designation of such
Junior Subordinated Debt Securities, aggregate principal amount and purchase
price; (ii) any limit on the aggregate principal amount of such Junior
Subordinated Debt Securities; (iii) the date or dates on which the principal of
such Junior Subordinated Debt Securities is payable and the right, if any, to
extend such date or dates; (iv) the rate or rates at which such Junior
Subordinated Debt Securities will bear interest or the method of calculating
such rate or rates, if any; (v) the date or dates from which such interest shall
accrue, the interest payment dates on which such interest will be payable or the
manner of determination of such interest payment dates and the record dates for
the determination of holders to whom interest is payable on any such interest
payment dates; (vi) the right, if any, to extend the interest payment periods
and the duration of such extension; (vii) the period or periods within which,
the price or prices at which, and the terms and conditions upon which, such
Junior Subordinated Debt Securities may be redeemed, in whole or in part, at the
option of the Company; (viii) the obligation, if any, of the Company to redeem
or purchase such Junior Subordinated Debt Securities pursuant to any sinking
fund or analogous provisions or at the option of the holder thereof and the
period or periods within which, the price or prices at which, and the terms and
conditions upon which, such Junior Subordinated Debt Securities shall be
redeemed or purchased, in whole or part, pursuant to such obligation; (ix) any
applicable United States Federal income tax consequences, including whether and
under what circumstances the Company will pay additional amounts on the Junior
Subordinated Debt Securities held by a person who is not a U.S. person in
respect of any tax, assessment or governmental charge withheld or deducted and,
if so, whether the Company will have the option to redeem such Junior
Subordinated Debt Securities rather than pay such additional amounts; (x) the
form of such Junior Subordinated Debt Securities; (xi) if other than
denominations of $25 or any integral multiple thereof, the denominations in
which such Junior Subordinated Debt Securities shall be issuable; (xii) any and
all other terms with respect to such series, including any modification of or
additions to the events of default or covenants provided for with respect to the
Junior Subordinated Debt Securities, and any terms which may be required by or
advisable under applicable laws or regulations not inconsistent with the
Indenture; and (xiii) whether such Junior Subordinated Debt Securities are
issuable as a global security, and in such case, the identity of the depositary.
(Section 2.01)
    
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures will be issued in United States dollars in fully
registered form without coupons in denominations of $25 or integral multiples
thereof. Junior Subordinated Debt Securities may be presented for exchange and
Junior Subordinated Debt Securities in registered form may be presented for
transfer in the manner, at the places and subject to the restrictions set forth
in the Junior Subordinated Debt Securities and the applicable Prospectus
Supplement. Such services will be provided without charge, other than any tax or
other governmental charge
 
                                       14
<PAGE>   52
 
payable in connection therewith, but subject to the limitations provided in the
Indenture. Junior Subordinated Debt Securities in bearer form and the coupons,
if any, appertaining thereto will be transferable by delivery.
 
     Junior Subordinated Debt Securities may bear interest at a fixed rate or a
floating rate. Junior Subordinated Debt Securities bearing no interest or
interest at a rate that at the time of issuance is below the prevailing market
rate will be sold at a discount below their stated principal amount. Special
United States Federal income tax considerations applicable to any such
discounted Junior Subordinated Debt Securities or to certain Junior Subordinated
Debt Securities issued at par which are treated as having been issued at a
discount for United States Federal income tax purposes will be described in the
applicable Prospectus Supplement.
 
CERTAIN COVENANTS OF THE COMPANY APPLICABLE TO THE JUNIOR SUBORDINATED DEBT
SECURITIES
 
   
     If Junior Subordinated Debt Securities are issued to a PWG Trust in
connection with the issuance of Trust Securities by such PWG Trust, the Company
will covenant in the Indenture that, so long as the Preferred Securities of such
PWG Trust remain outstanding, the Company will not declare or pay any dividends
on, or redeem, purchase, acquire or make a distribution or liquidation payment
with respect to, any of its common stock or preferred stock or make any
guarantee payments with respect thereto if at such time (i) the Company shall be
in default with respect to its Guarantee Payments or other payment obligations
under the related Preferred Securities Guarantee or (ii) there shall have
occurred any Indenture Event of Default with respect to such Junior Subordinated
Debt Securities provided, however, that the foregoing restrictions shall not
apply to (i) dividends, redemptions, purchases, acquisitions, distributions or
payments made by the Company by way of issuance of shares of its capital stock,
(ii) payments of accrued dividends by the Company upon the redemption, exchange
or conversion of any preferred stock of the Company as may be outstanding from
time to time in accordance with the terms of such preferred stock or (iii) cash
payments made by the Company in lieu of delivering fractional shares upon the
redemption, exchange or conversion of any preferred stock of the Company as may
be outstanding from time to time in accordance with the terms of such preferred
stock. In addition, if Junior Subordinated Debt Securities are issued to a PWG
Trust in connection with the issuance of Trust Securities by such PWG Trust, for
so long as the Preferred Securities of such PWG Trust remain outstanding, the
Company has agreed (i) to remain the sole direct or indirect owner of all the
outstanding Common Securities issued by such PWG Trust and not to cause or
permit such Common Securities to be transferred except to the extent permitted
by the Declaration of such PWG Trust; provided that any permitted successor of
the Company under the Indenture may succeed to the Company's ownership of such
Common Securities, (ii) to comply fully with all its obligations and agreements
under such Declaration and (iii) not to take any action which would cause such
PWG Trust to cease to be treated as a grantor trust for United States Federal
income tax purposes, except in connection with a distribution of Junior
Subordinated Debt Securities.
    
 
SUBORDINATION
 
     The Indenture provides that the Junior Subordinated Debt Securities are
subordinate and junior in right of payment to all Senior Indebtedness of the
Company. No payment by the Company on account of principal of (or premium, if
any) or any interest on the Junior Subordinated Debt Securities may be made if
any default or event of default with respect to any Senior Indebtedness shall
have occurred and be continuing and written notice thereof shall have been given
to the Indenture Trustee by the Company or to the Company and the Indenture
Trustee by the holders of at least 10% in principal amount of any kind or
category of any Senior Indebtedness (or a representative or trustee on their
behalf). Upon any acceleration of the principal due on the Junior Subordinated
Debt Securities or any payment or distribution of assets of the Company to
creditors upon any dissolution, winding up, liquidation or reorganization,
whether voluntary or involuntary or in bankruptcy, insolvency, receivership or
other proceedings, all principal of (and premium, if any) and interest due or to
become due on all Senior Indebtedness must be paid in full before the holders of
Junior Subordinated Debt Securities will be entitled to receive or retain any
payment (other than shares of stock or subordinated indebtedness provided by a
plan of reorganization or adjustment which does not alter the rights of holders
of Senior Indebtedness). Subject to the payment in full of all Senior
Indebtedness, the holders of
 
                                       15
<PAGE>   53
 
the Junior Subordinated Debt Securities are to be subrogated to the rights of
the holders of Senior Indebtedness to receive payments or distributions of
assets of the Company applicable to Senior Indebtedness until the Junior
Subordinated Debt Securities are paid in full. By reason of such subordination,
in the event of insolvency, creditors of the Company who are holders of Senior
Indebtedness, as well as general creditors of the Company, may recover more,
ratably, than the holders of the Junior Subordinated Debt Securities. If this
Prospectus is being delivered in connection with a series of Junior Subordinated
Debt Securities, the accompanying Prospectus Supplement will set forth the
approximate amount of Senior Indebtedness outstanding as of the end of the most
recent fiscal quarter.
 
   
     The term "Senior Indebtedness" shall mean (i) the principal of, premium, if
any, and accrued and unpaid interest on (a) indebtedness of the Company for
money borrowed, whether outstanding on the date of execution of the Indenture or
thereafter created, incurred or assumed, (b) guarantees by the Company of
indebtedness for money borrowed by any other person, whether outstanding on the
date of execution of the Indenture or thereafter created, incurred or assumed,
(c) indebtedness evidenced by notes, debentures, bonds or other instruments of
indebtedness for the payment of which the Company is responsible or liable, by
guarantees or otherwise, whether outstanding on the date of execution of the
Indenture or thereafter created, incurred or assumed, and (d) obligations of the
Company under any agreement to lease, or any lease of, any real or personal
property, whether outstanding on the date of execution of the Indenture or
thereafter created, incurred or assumed, (ii) any other indebtedness, liability
or obligation, contingent or otherwise, of the Company and any guarantee,
endorsement or other contingent obligation of the Company in respect of any
indebtedness, liability or obligation, whether outstanding on the date of
execution of the Indenture or thereafter created, incurred or assumed, and (iii)
modifications, renewals, extensions and refundings of any such indebtedness,
liabilities, obligations or guarantees; unless, in the instrument creating or
evidencing the same or pursuant to which the same is outstanding, it is provided
that such indebtedness, liabilities, obligations or guarantees, or such
modification, renewal, extension or refunding thereof, are not superior in right
of payment to the Junior Subordinated Debt Securities; provided, however, that
Senior Indebtedness shall not include any obligation of the Company to any
Subsidiary. Notwithstanding anything to the contrary in the Indenture or the
Junior Subordinated Debt Securities, Senior Indebtedness shall not include any
indebtedness of the Company which, by its terms or the terms of the instrument
creating or evidencing it, is subordinate in right of payment to, or pari passu
with, the Junior Subordinated Debt Securities, as the case may be. The Indenture
does not contain any limitation on the amount of Senior Indebtedness that can be
incurred by the Company.
    
 
   
     The Company's rights and the rights of its creditors (including holders of
Senior Indebtedness and Junior Subordinated Debt Securities) to participate in
any distribution of assets of any subsidiary of the Company upon its liquidation
or reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized. Also, dividend
payments and advances to the Company by PaineWebber are restricted by the
provisions of the net capital rules of the Commission and the NYSE and covenants
in various loan agreements. The operations of the Company are conducted through
its subsidiaries and, therefore, the Company is dependent upon the earnings and
cash flow of its subsidiaries to meet its obligations, including obligations
under the Senior Indebtedness and Junior Subordinated Debt Securities. The
Senior Indebtedness and Junior Subordinated Debt Securities will be effectively
subordinated to all indebtedness of the Company's subsidiaries. As of September
30, 1996, the aggregate amount of indebtedness of the Company's subsidiaries
(such indebtedness consisting of short-term borrowings and excluding short-term
and long-term borrowings owed directly or indirectly to the Company or another
subsidiary) to which holders of the Senior Indebtedness and Junior Subordinated
Debt Securities would have been structurally subordinated was approximately $405
million.

INDENTURE EVENTS OF DEFAULT
 
   
     The Indenture provides that any one or more of the following described
events, which has occurred and is continuing, constitutes an "Indenture Event of
Default" with respect to a series of Junior Subordinated Debt Securities:
    
 
          (a) failure for 30 days to pay interest on the Junior Subordinated
     Debt Securities of such series when due; provided that a valid extension of
     the interest payment period by the Company shall not constitute a default
     in the payment of interest for this purpose;
 
          (b) failure to pay principal of or premium, if any, on the Junior
     Subordinated Debt Securities of such series when due whether at maturity,
     upon redemption, by declaration or otherwise;
 
          (c) failure to observe or perform any other covenant contained in the
     Indenture with respect to such series for 90 days after written notice to
     the Company from the Indenture Trustee or the holders of at least 25% in
     principal amount of the outstanding Junior Subordinated Debt Securities of
     such series; or
 
          (d) certain events in bankruptcy, insolvency or reorganization of the
     Company.
 
In each and every such case, unless the principal of all the Junior Subordinated
Debt Securities of such series shall have already become due and payable, either
the Indenture Trustee or the holders of not less than 25% in aggregate principal
amount of the Junior Subordinated Debt Securities of such series then
outstanding, by notice in writing to the Company (and to the Indenture Trustee
if given by such holders), may declare the principal of all the Junior
Subordinated Debt Securities of such series to be due and payable immediately,
and upon any such declaration the same shall become and shall be immediately due
and payable. (Section 6.01)
 
     The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debt Securities of the applicable series have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Indenture Trustee. (Section 6.06) The Indenture Trustee or the
holders of not less than 25% in aggregate outstanding principal amount of the
Junior Subordinated Debt Securities of such series may declare the principal due
and payable immediately upon an Indenture Event of Default with respect to such
series, but the holders of a majority in aggregate outstanding principal amount
of Junior Subordinated Debt Securities of such series may annul such declaration
and waive the default if the default has been cured and a sum sufficient to pay
all matured installments of interest and principal otherwise than by
acceleration and any premium has been deposited with the Indenture Trustee.
(Sections 6.01 and 6.06)
 
     The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debt Securities of a series may, on behalf of the holders of
all the Junior Subordinated Debt Securities of such series, waive any past
default, except a default in the payment of principal, premium, if any, or
interest on Junior Subordinated Securities of such series (unless such default
has been cured and a sum sufficient to pay all matured installments of interest
and principal otherwise than by acceleration and any premium has been deposited
with the Indenture Trustee) or a call for redemption of Junior Subordinated Debt
Securities of such series. (Section 6.06) The Company is required to file
annually with the Indenture Trustee a certificate as to whether or not the
Company is in compliance with all the conditions and covenants under the
Indenture. (Section 5.03)
 
     If a series of Junior Subordinated Debt Securities is issued to a PWG Trust
in connection with the issuance of Trust Securities of such PWG Trust, then,
under the applicable Declaration, an Indenture Event of Default with respect to
such series of Junior Subordinated Debt Securities will constitute a Declaration
Event of Default.
 
MODIFICATION OF THE INDENTURE
 
   
     The Indenture provides that the Company and the Indenture Trustee may,
without the consent of any holders of Junior Subordinated Debt Securities, enter
into supplemental indentures for the purposes, among other things, of adding to
the Company's covenants, adding additional Events of Default, establishing the
form or terms of any series of Junior Subordinated Debt Securities or, provided
such action shall not adversely
    
 
                                       17
<PAGE>   55
 
   
affect the interests of the holders of any series of Junior Subordinated Debt
Securities in any material respect, curing ambiguities or inconsistencies in
such Indenture or making other provisions. (Section 9.01)
    
 
     The Indenture contains provisions permitting the Company and the Indenture
Trustee, with the consent of the holders of not less than a majority in
principal amount of the outstanding Junior Subordinated Debt Securities of each
series affected thereby, to modify the Indenture or any supplemental indenture
affecting the rights of the holders of such Junior Subordinated Debt Securities;
provided that no such modification may, without the consent of the holder of
each outstanding Junior Subordinated Debt Security affected thereby, (i) extend
the fixed maturity of any Junior Subordinated Debt Securities of any series,
reduce the principal amount thereof, reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Junior Subordinated Debt
Security so affected, or (ii) reduce the percentage of Junior Subordinated Debt
Securities, the holders of which are required to consent to any such
modification, without the consent of the holders of each Junior Subordinated
Debt Security then outstanding and affected thereby. (Section 9.02)
 
BOOK ENTRY AND SETTLEMENT
 
     If any Junior Subordinated Debt Securities of a series are represented by
one or more global securities (each, a "Global Security"), the applicable
Prospectus Supplement will describe the circumstances, if any, under which
beneficial owners of interests in any such Global Security may exchange such
interests for Junior Subordinated Debt Securities of such series and of like
tenor and principal amount in any authorized form and denomination. Principal
of, and any premium and interest on, a Global Security will be payable in the
manner described in the applicable Prospectus Supplement.
 
     The specific terms of the depositary arrangement with respect to any
portion of a series of Junior Subordinated Debt Securities to be represented by
a Global Security will be described in the applicable Prospectus Supplement.
 
CONSOLIDATION, MERGER AND SALE
 
   
     The Indenture will provide that the Company, without the consent of the
Holders of any of the Junior Subordinated Debt Securities, may consolidate with
or merge into any other Person or convey, transfer or lease its assets
substantially as an entirety to any Person or may acquire or lease the assets of
any Person substantially as an entirety or may permit any Person to consolidated
with or merge into the Company or convey, transfer or lease its properties and
assets substantially as an entirety to the Company provided that: (i) the
successor is a corporation organized under the laws of any domestic
jurisdiction; (ii) the successor corporation, if other than the Company, assumes
the Company's obligations under the Indenture and the Junior Subordinated Debt
Securities issued thereunder, (iii) immediately after giving effect to the
transaction, no Event of Default and no event that, after notice or lapse of
time, or both, would become an Event of Default, shall have occurred and be
continuing; and (iv) certain other conditions are met. (Section 10.01)
    
 
DEFEASANCE AND DISCHARGE
 
     Under the terms of the Indenture, the Company will be discharged from any
and all obligations in respect of the Junior Subordinated Debt Securities of a
series (except in each case for certain obligations to register the transfer or
exchange of such Junior Subordinated Debt Securities, replace stolen, lost or
mutilated Junior Subordinated Debt Securities of such series, maintain paying
agencies and hold moneys for payment in trust) if (i) the Company irrevocably
deposits with the Indenture Trustee cash or U.S. Government Obligations, as
trust funds, in an amount certified to be sufficient to pay at maturity (or upon
redemption) the principal of, premium, if any, and interest on all outstanding
Junior Subordinated Debt Securities of such series; (ii) such deposit will not
result in a breach or violation of, or constitute a default under, any agreement
or instrument to which the Company is a party or by which it is bound; (iii) the
Company delivers to the Indenture Trustee an opinion of counsel to the effect
that the holders of the Junior Subordinated Debt Securities of such series will
not recognize income, gain or loss for United States Federal income tax purposes
as a result of such defeasance and that such defeasance will not otherwise alter
holders' United States Federal income tax

treatment of principal, premium and interest payments on the Junior Subordinated
Debt Securities of such series (such opinion must be based on a ruling of the
Internal Revenue Service or a change in United States Federal income tax law
occurring after the date of such Indenture, since such a result would not occur
under current tax law); (iv) the Company delivers to the Indenture Trustee an
Officers' Certificate and an opinion of counsel, each stating that all
conditions precedent provided for relating to the defeasance contemplated by
such provision have been complied with; and (v) no event or condition shall
exist that, pursuant to the subordination provisions applicable to the Junior
Subordinated Debt Securities of such series, would prevent the Company from
making payments of principal of, premium, if any, and interest on the Junior
Subordinated Debt Securities of such series at the date of the irrevocable
deposit referred to above. (Section 11.01)
 
GOVERNING LAW
 
     The Indenture and the Junior Subordinated Debt Securities will be governed
by, and construed in accordance with, the laws of the State of New York.
(Section 13.05)
 
INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
     The Indenture Trustee, prior to default, undertakes to perform only such
duties as are specifically set forth in the Indenture and, after default, shall
exercise the same degree of care as a prudent individual would exercise in the
conduct of his or her own affairs. (Section 7.01) Subject to such provision, the
Indenture Trustee 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 Debt
Securities, unless offered reasonable indemnity by such holder against the
costs, expenses and liabilities that might be incurred thereby. (Section 7.02)
The Indenture 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 Indenture Trustee reasonably believes that repayment or adequate indemnity
is not reasonably assured to it. (Section 7.01)
 
     The Chase Manhattan Bank is a depositary for funds and performs other
services for, and transacts other banking business with, the Company in the
normal course of business.
 
MISCELLANEOUS
 
     The Company will have the right at all times to assign any of its rights or
obligations under the Indenture to a direct or indirect wholly owned subsidiary
of the Company; provided that, in the event of any such assignment, the Company
will remain jointly and severally liable for all such obligations. Subject to
the foregoing, the Indenture will be binding upon and inure to the benefit of
the parties thereto and their respective successors and assigns. The Indenture
provides that it may not otherwise be assigned by the parties thereto other than
by the Company to a successor or purchaser pursuant to a consolidation, merger
or sale permitted by the Indenture. (Section 13.11)
 
                                 ERISA MATTERS
 
     The Company, PaineWebber and other affiliates of the Company may each be
considered a "party in interest" (within the meaning of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) or a "disqualified person"
(within the meaning of Section 4975 of the Internal Revenue Code of 1986, as
amended (the "Code")) with respect to many employee benefit plans ("Plans") that
are subject to ERISA. The purchase of Offered Securities by a Plan that is
subject to the fiduciary responsibility provisions of ERISA or the prohibited
transaction provisions of Section 4975 of the Code (including individual
retirement arrangements and other plans described in Section 4975(e)(1) of the
Code) and with respect to which the Company, PaineWebber or any other affiliate
of the Company is a service provider (or otherwise is a party in interest or a
disqualified person) may constitute or result in a prohibited transaction under
ERISA or Section 4975 of the Code, unless such Offered Securities are acquired
pursuant to and in accordance with an applicable exemption. Any pension or other
employee benefit plan proposing to acquire any Offered Securities should consult
with its counsel.

                              PLAN OF DISTRIBUTION
 
     The Company may sell any series of Junior Subordinated Debt Securities and
the PWG Trusts may sell the Preferred Securities being offered hereby (i)
directly to one or more purchasers, (ii) through agents designated from time to
time and/or (iii) through underwriters or dealers or a group of underwriters.
The applicable Prospectus Supplement will set forth the terms of the offering of
any Offered Securities, including the name or names of any underwriters, the
purchase price of the Offered Securities and the proceeds to the Company and/or
any PWG Trust from such sale, any underwriting discounts and other items
constituting underwriters' compensation, any initial public offering price and
any discounts or concessions allowed or reallowed or paid to dealers and any
securities exchanges on which the Offered Securities may be listed. If a bidding
or auction process is utilized, it will be described in the applicable
Prospectus Supplement.
 
     If underwriters are used in the sale, Offered Securities will be acquired
by the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The Offered
Securities may be offered to the public either through underwriting syndicates
represented by managing underwriters or by underwriters without a syndicate.
Unless otherwise set forth in the applicable Prospectus Supplement, the
obligations of the underwriters to purchase the Offered Securities will be
subject to certain conditions precedent, and the underwriters will be obligated
to purchase all the Offered Securities if any are purchased. Any initial public
offering price and any discounts or concessions allowed or reallowed or paid to
dealers may be changed from time to time.
 
     Offered Securities may be sold directly by the Company or through agents
designated by the Company from time to time. Any agent involved in the offer or
sale of Offered Securities will be named, and any commissions payable by the
Company to such agents will be set forth, in the applicable Prospectus
Supplement. Unless otherwise indicated in the applicable Prospectus Supplement,
any such agent will be acting on a best efforts basis for the period of its
appointment.
 
     If so indicated in the applicable Prospectus Supplement, the Company will
authorize agents, underwriters or dealers to solicit offers by certain specified
institutions to purchase Offered Securities from the Company at the public
offering price set forth in such Prospectus Supplement pursuant to delayed
delivery contracts providing for payment and delivery on a specified date in the
future. Such contracts will be subject only to those conditions set forth in the
applicable Prospectus Supplement and such Prospectus Supplement will set forth
the commission payable for the solicitation of such contracts.
 
     Any underwriters, dealers or agents participating in the distribution of
Offered Securities may be deemed to be underwriters and any discounts or
commissions received by them on the sale or resale of Offered Securities may be
deemed to be underwriting discounts and commissions under the Securities Act.
Agents and underwriters may be entitled under agreements entered into with the
Company to indemnification by the Company against certain liabilities, including
liabilities under the Securities Act, or to contribution with respect to
payments which the agents or underwriters may be required to make in respect
thereof. Agents and underwriters may be customers of, engage in transactions
with, or perform services for, the Company in the ordinary course of business.
 
     All Offered Securities will be a new issue of securities with no
established trading market. Certain agents through whom, and underwriters to
whom, Offered Securities are sold by the Company for public offering and sale
may make a market in such Offered Securities, but such agents and underwriters
will not be obligated to do so and may discontinue any market making at any time
without notice. No assurance can be given as to the liquidity of the trading
market for any Offered Securities.
 
     PaineWebber or one or more other affiliates of the Company may participate
in distributions of the Offered Securities. All distributions of the Offered
Securities will conform to the requirements set forth in the applicable sections
of Rule 2720 of the Conduct Rules of the NASD.

                                  THE COMPANY
 
     Paine Webber Group Inc. is a holding company which, together with its
operating subsidiaries, forms one of the largest full-service securities and
commodities firms in the industry. Founded in 1879, the Company employs
approximately 15,800 people in 302 offices worldwide.
 
     The Company's principal line of business is to serve the investment and
capital needs of individual, corporate, institutional and public agency clients
through its broker-dealer subsidiary, PaineWebber, and other specialized
subsidiaries. The Company holds memberships in all major securities and
commodities exchanges in the United States, and makes a market in many
securities traded on Nasdaq National Market or on other over-the-counter
markets. Additionally, PaineWebber is a primary dealer in U.S. government
securities.
 
     The Company is comprised of interrelated business groups, including

890 companies in 62 industry sectors.
 
     The Private Client Group consists primarily of a domestic branch office
system and consumer product groups through which PaineWebber and certain other
subsidiaries provide clients with financial services and products, including the
purchase and sale of securities, option contracts, commodity and financial
futures contracts, fixed income instruments, mutual funds, trusts and selected
insurance products. The Company may act as a principal or agent in providing
these services. Fees charged vary according to the size and complexity of a
transaction, and the activity level of a client's account.
 
     The Municipal Securities Group originates, underwrites, sells and trades
taxable and tax-exempt issues for municipal and public agency clients.
 
     Through the Investment Banking group, the Company provides financial advice
to, and raises capital for, a broad range of domestic and international
corporate clients. Investment Banking manages and underwrites public and private
offerings, participates as an underwriter in syndicates of public offerings
managed by others, and provides advice in connection with mergers and
acquisitions, restructurings and recapitalizations.

management services to individuals and mutual funds. MHIA provides portfolio
management services to individuals, trusts and institutions.
 
     Through the Global Fixed Income and Global Equities Groups, the Company
places securities for, and executes trades on behalf of, institutional clients
both domestically and internationally. In addition, the Company takes positions
in both listed and over-the-counter equity securities and fixed income
securities to facilitate client transactions or for the Company's own account.
 
     The Commercial Real Estate Group provides a full range of capital market
services to real estate clients, including underwriting of debt and equity
securities, principal lending activity, debt restructuring, property sales and
bulk sales services, and a broad range of other advisory services.
 
     The Transaction Services Group includes correspondent services, prime
brokerage and securities lending businesses, and specialist trading. Through
Correspondent Services Corporation, the Company provides execution and clearing
services to broker-dealers in the U.S. and overseas. The Company also acts as a
specialist responsible for executing transactions and maintaining an orderly
market in certain securities.
 
     The Company's businesses operate in one of the nation's most highly
regulated industries. Violations of applicable regulations can result in the
revocation of broker-dealer licenses, the imposition of censures or fines, and
the suspension or expulsion of a firm. The Company's businesses are regulated by
various agencies, including the Commission, the NYSE, the Commodity Futures
Trading Commission and the National Association of Securities Dealers, Inc. (the

     The statements under this heading are subject to the detailed provisions of

<PAGE>   64
 
GENERAL
 
     The Securities of a series may be issued in fully registered form without
Coupons ("Registered Securities") or in bearer form with or without Coupons
attached ("Bearer Securities") or both. Securities of a series may also be
issued in whole or in part in the form of one or more global securities (each, a
"Global Security"). Unless otherwise specified in the applicable Prospectus
Supplement, the Securities will be only Registered Securities. Registered
Securities which are book-entry securities ("Book-Entry Securities") may be
issued in the form of registered Global Securities. Securities denominated in
U.S. dollars will be issued, unless otherwise set forth in the applicable
Prospectus Supplement, in denominations of $1,000 or an integral multiple
thereof for Registered Securities, and only in the denomination of $5,000 for
Bearer Securities. (Section 302)
 
     Neither of the Indentures limits the aggregate principal amount of
Securities which may be issued thereunder. The Securities will be direct,
unsecured obligations of the Company. The Subordinated Securities will be
subordinated in right of payment, to the extent and in the manner set forth in
the Subordinated Indenture, to the prior payment in full of all Superior
Indebtedness as described below under "Subordination."
 
     If any of the Securities are sold for any foreign currency or composite
currency or if principal of (or premium, if any) or any interest on any of the
Securities is payable in any foreign currency or composite currency, the
restrictions, elections, Federal income tax consequences, specific terms and
other information with respect to such issue of Securities and such foreign
currency or composite currency will be set forth in the Prospectus Supplement
relating thereto.
 
     If the amount of payments of principal of (or premium, if any) or any
interest on any of the Securities is determined with reference to any type of
index or formula or changes in prices of particular securities, currencies,
intangibles, goods, articles or commodities, the Federal income tax
consequences, specific terms and other information with respect to such issue of
Securities and such index or formula, securities, currencies, intangibles,
goods, articles or commodities will be set forth in the Prospectus Supplement
relating thereto.
 
     The Securities may be issued in one or more series with the same or various
maturities at or above par or with an original issue discount. Certain
Securities may be issued which provide for an amount less than the principal
amount thereof to be due and payable in the event of an acceleration of the
maturity thereof (each an "Original Issue Discount Security"), including by
reason of redemption or early repayment. Original Issue Discount Securities may
bear no interest or may bear interest at a rate which at the time of issuance is
below market rates and will be sold at a discount (which may be substantial)
below their stated principal amount. Certain Original Issue Discount Securities
may be issued with original issue discount for United States Federal income tax
purposes. The Prospectus Supplement with respect to any Offered Securities
issued with such original issue discount will contain a discussion of Federal
income tax considerations with respect thereto.
 
   
     Reference is made to the Prospectus Supplement for the following terms of
the Offered Securities: (i) the title and any limit on the aggregate principal
amount of the Offered Securities and whether the Offered Securities are Senior
Securities or Subordinated Securities; (ii) the percentage of their principal
amount at which the Offered Securities will be issued; (iii) the date or dates
on which the Offered Securities will mature; (iv) the rate or rates (which may
be fixed or variable) per annum, if any, at which the Offered Securities will
bear interest or the method of determining such rate or rates; (v) the date or
dates from which such interest, if any, will accrue and the date or dates at
which such interest, if any, will be payable; (vi) the place where the principal
of (and premium, if any) and interest, if any, on the Offered Securities will be
payable; (vii) the terms for redemption or early repayment, if any, including
any mandatory or optional sinking fund or analogous provision; (viii) the terms,
if any, on which the Offered Securities may be converted into or exchanged for
stock or other securities of the Company or other entities, any specific terms
relating to the adjustment thereof and the period during which the Offered
Securities may be so converted or exchanged; (ix) the principal amount of any
Offered Securities which are Original Issue Discount Securities that is payable
upon acceleration of the maturity of such Offered Securities; (x) if other than
U.S. dollars, the currency, currencies, composite currency or composite
currencies for which the Offered Securities may be purchased and the currency,
currencies, composite currency or composite currencies in which the payment of
principal of (or premium, if any) or any interest on such Offered Securities
will be made and, if the Company
    
 
                                        5
<PAGE>   65
 
   
or the Holders of Offered Securities may elect to receive such payment in a
currency, currencies, composite currency or composite currencies other than that
in which the Offered Securities are stated to be payable, then, the period or
periods within which, and the terms and conditions upon which, such election may
be made and, if the amount of such payments may be determined with reference to
an index based on a currency, currencies, composite currency or composite
currencies other than that in which the Offered Securities are stated to be
payable, then the manner in which such amounts shall be determined; (xi) whether
the Offered Securities will be issued as Registered Securities or Bearer
Securities or both and the terms upon which any Bearer Securities of such series
may be exchanged for Registered Securities of such series; (xii) whether the
Offered Securities are to be issued in whole or in part in the form of one or
more Global Securities and, if so, the identity of the depositary or
depositaries for such Global Security or Securities; (xiii) if a temporary
Global Security is to be issued with respect to some of or all the Offered
Securities, any requirements for certification of ownership by non-United States
persons that will apply prior to (a) the issuance of a definitive Security or
(b) the payment of interest on an interest payment date that occurs before the
issuance of a definitive Security; (xiv) if a temporary Global Security is to be
issued with respect to some of or all the Offered Securities, the terms upon
which interests in such temporary Global Security may be exchanged for interests
in a definitive Global Security or for definitive Securities and the terms upon
which interests in a definitive Global Security, if any, may be exchanged for
definitive Securities; (xv) whether and under what circumstances the Company
will pay additional amounts to certain Holders of Offered Securities in respect
of any tax, assessment or governmental charge required to be withheld or
deducted and, if so, whether the Company will have the option to redeem such
Offered Securities rather than pay any additional amounts; (xvi) if the amount
of payments of principal of (or premium, if any) or any interest on the Offered
Securities may be determined with reference to an index based on the prices,
changes in prices, or differences between prices, of securities, currencies,
intangibles, goods, articles or commodities, or otherwise by application of a
formula, the manner in which such amounts shall be determined; (xvii) any
additional Events of Default (as defined below under "Events of Default, Notice
and Waiver") or restrictive covenants provided for with respect to the Offered
Securities; and (xviii) any other terms of the Offered Securities not
inconsistent with the applicable Indenture.
    
 
     If any Offered Securities are Bearer Securities, the Prospectus Supplement
will describe any applicable restrictions (including, without limitation, any
restrictions required to comply with United States Federal income tax laws and
regulations) on the offer, sale and delivery of such Bearer Securities in
addition to those set forth under "Limitations on Issuance of Bearer
Securities."
 
     Each Indenture provides that, at the option of the Company, interest on the
Registered Securities of any series that bears interest may be paid by mailing a
check to the address of the Person entitled thereto as such address shall appear
in the Security Register. (Section 301)
 
     The Indentures do not prohibit (i) a consolidation, merger or sale of
assets or other similar transactions that may adversely affect the
creditworthiness of the Company or a successor or combined entity, (ii) a change
of control of the Company or (iii) leveraged transactions involving the Company
whether or not involving a change of control. In addition, under the terms of
the Indentures the Company is entitled to defease the Offered Securities. As a
result, the Indentures do not protect Holders against a substantial decline in
the value of the Offered Securities which may result from the aforementioned
transactions.
 
EXCHANGE, REGISTRATION AND TRANSFER
 
   
     Registered Securities (other than a Global Security, except as provided
below) of any series will be exchangeable for other Registered Securities of the
same series and of a like aggregate principal amount and tenor of any authorized
denominations. In addition, if Securities of any series are issuable as both
Registered Securities and Bearer Securities, at the option of the Holder, and
subject to the terms of the applicable Indenture, Bearer Securities (with all
unmatured Coupons, except as provided below, and all matured Coupons in default)
of such series will be exchangeable into Registered Securities of the same
series of any authorized denominations and of a like aggregate principal amount
and tenor. Bearer Securities with coupons appertaining thereto surrendered in
exchange for Registered Securities between a Regular Record Date or a Special
Record Date and the relevant date for payment of interest shall be surrendered
without the Coupon
    
 
                                        6
<PAGE>   66
 
relating to such date for payment of interest and interest will not be payable
on such date in respect of the Registered Security issued in exchange for such
Bearer Security, but will be payable only to the Holder of such Coupon when due
in accordance with the terms of the applicable Indenture. Bearer Securities will
not be issued in exchange for Registered Securities. (Section 305)
 
     No service charge will be made for any transfer or exchange of the
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge in connection therewith. (Section 305)
 
   
     Securities may be presented for exchange as provided above, and Registered
Securities (other than a Global Security, except as provided below) may be
presented for registration of transfer (duly endorsed, or accompanied by a
satisfactory instrument of transfer), at the office of the Security Registrar or
at the office of any transfer agent designated by the Company for such purpose
with respect to any series of Securities and referred to in an applicable
Prospectus Supplement, without service charge and upon payment of any taxes and
other governmental charges as described in the applicable Indenture. The Company
has appointed The Chase Manhattan Bank as Security Registrar for each Indenture.
(Section 305) If a Prospectus Supplement refers to any transfer agents (in
addition to the Security Registrar) initially designated by the Company with
respect to any series of Securities, the Company 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, except that, if Securities of a
series are issuable solely as Registered Securities, the Company will be
required to maintain a transfer agent in each Place of Payment for such series
and, if Securities of a series are issuable as Bearer Securities, the Company
will be required to maintain (in addition to the Security Registrar) a transfer
agent in a Place of Payment for such series located outside the United States.
The Company may at any time designate additional transfer agents with respect to
any series of Securities. (Section 1002)
    
 
     The Company shall not be required to: (i) issue, register the transfer of
or exchange Securities of any series during a period beginning at the opening of
business 15 days before any selection of Securities of that series to be
redeemed and ending at the close of business on (a) if Securities of the series
are issuable only as Registered Securities, the day of mailing of the relevant
notice of redemption and (b) if Securities of the series are issuable as Bearer
Securities, the day of the first publication of the relevant notice of
redemption or, if Securities of the series are also issuable as Registered
Securities and there is no publication, the day of mailing of the relevant
notice of redemption; (ii) register the transfer of or exchange any Registered
Security, or portion thereof, called for redemption, except the unredeemed
portion of any Registered Security being redeemed in part; or (iii) exchange any
Bearer Security called for redemption, except to exchange such Bearer Security
for a Registered Security of that series and like tenor which is simultaneously
surrendered for redemption. (Section 305)
 
     For a discussion of restrictions on the exchange, registration and transfer
of Global Securities, see "Global Securities" below.
 
PAYMENT AND PAYING AGENTS
 
     Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Bearer Securities will
be payable, subject to any applicable laws and regulations, at the offices of
such Paying Agents outside the United States as the Company may designate from
time to time and payment of interest on Bearer Securities with Coupons
appertaining thereto will be made only against surrender of the Coupon relating
to the applicable Interest Payment Date. (Sections 311 and 1002) Unless
otherwise indicated in an applicable Prospectus Supplement, no payment with
respect to any Bearer Security will be made at any office or agency of the
Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States. Notwithstanding the foregoing, payments of principal of (and premium, if
any) and any interest on Bearer Securities denominated and payable in U.S.
dollars will be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment of the full amount
thereof in U.S. dollars at all offices or agencies outside the United States is
illegal or effectively precluded by exchange controls or other similar
restrictions. (Section 1002)
 
                                        7
<PAGE>   67
 
     Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Registered Securities
will be made at the office of such Paying Agent or Paying Agents as the Company
may designate from time to time, except that at the option of the Company
payment of any interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register. (Section
301) Unless otherwise indicated in an applicable Prospectus Supplement, payment
of any installment of interest on Registered Securities will be made to the
Person in whose name such Registered Security is registered at the close of
business on the Regular Record Date for such interest. (Section 307)
 
     Unless otherwise indicated in an applicable Prospectus Supplement, the
Corporate Trust Office of The Chase Manhattan Bank in the Borough of Manhattan,
The City of New York, will be designated as the Company's Paying Agent in the
Borough of Manhattan, The City of New York, for payments with respect to Offered
Securities (subject to the limitation described above in the case of Bearer
Securities). Any Paying Agents outside the United States and any other Paying
Agents in the United States initially designated by the Company for the Offered
Securities will be named in an applicable Prospectus Supplement. The Company may
at any time designate additional Paying Agents or rescind the designation of any
Paying Agent or approve a change in the office through which any Paying Agent
acts, except that, if Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a Paying Agent in each
Place of Payment for such series and, if Securities of a series are issuable as
Bearer Securities, the Company will be required to maintain (i) a Paying Agent
in the Borough of Manhattan, The City of New York, for payments with respect to
any Registered Securities of the series (and for payments with respect to Bearer
Securities of the series in the circumstances described above, but not
otherwise), and (ii) a Paying Agent in a Place of Payment located outside the
United States where Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment; provided that if any of
the Securities of such series are listed on The International Stock Exchange of
the United Kingdom and the Republic of Ireland Limited, the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such
stock exchange shall so require, the Company will maintain a Paying Agent in
London, Luxembourg or any other required city located outside the United States,
as the case may be, for the Securities or such series. (Section 1002)
 
     All money paid by the Company to a Paying Agent for the payment of
principal of (or premium, if any) or any interest on any Security or Coupon that
remains unclaimed at the end of two years after such principal, premium or
interest shall have become due and payable will be repaid to the Company and the
Holder of such Security or Coupon will thereafter look only to the Company for
payment thereof. (Section 1003)
 
     If so specified in an applicable Prospectus Supplement, the Company may, at
its option, defer payments of interest otherwise payable on an Interest Payment
Date for a period and upon the terms and conditions described in such Prospectus
Supplement.
 
GLOBAL SECURITIES
 
     If so specified in an applicable Prospectus Supplement, all or any portion
of the Securities of a series may be issued in the form of one or more Global
Securities that will be deposited with, or on behalf of, a depositary (a
"Depositary") identified in the Prospectus Supplement relating to such series.
Global Securities may be issued in either registered or bearer form and in
either temporary or definitive form. The specific terms of the depositary
arrangement with respect to any Securities of a series will be described in the
Prospectus Supplement relating to such series. Unless otherwise specified in the
applicable Prospectus Supplement, the Company anticipates that the following
provisions will apply to all depositary arrangements.
 
     Securities which are to be represented by a Global Security to be deposited
with or on behalf of a Depositary will be represented by a Global Security
registered in the name of such Depositary or its nominee. Upon the issuance of a
Global Security, the Depositary for such Global Security will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the Securities represented by such Global Security to the accounts of
institutions that have accounts with such Depositary or its nominee
("participants"). The accounts to be credited shall be designated by the
underwriters of such Securities, by certain
 
                                        8
<PAGE>   68
 
agents of the Company or by the Company, if such Securities are offered and sold
directly by the Company. Ownership of beneficial interests in a Global Security
will be limited to participants or persons that may hold interests through
participants. Ownership of a beneficial interest in such Global Security will be
shown on, and the transfer of that ownership will be effected only through,
records maintained by the Depositary or its nominee (with respect to
participants' interests) for such Global Security or by participants or persons
that hold through participants. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to transfer
beneficial interests in a Global Security.
 
     So long as the Depositary for a Global Security, or its nominee, is the
owner of such Global Security, such Depositary or such nominee, as the case may
be, will be considered the sole owner or holder of the Securities represented by
such Global Security for all purposes under the Indenture governing such
Securities. Except as set forth below, owners of beneficial interests in a
Global Security will not be entitled to have Securities of the series
represented by such Global Security registered in their names, will not receive
or be entitled to receive physical delivery of Securities of such series in
definitive form and will not be considered the owners or holders thereof under
the Indenture governing such Securities. Accordingly, each person owning a
beneficial interest in a Global Security must rely on the procedures of the
Depositary for such Global Security and, if such person is not a participant, on
the procedures of the participant and, if applicable, the indirect participant,
through which such person owns its interest, to exercise any rights of a holder
under such Indenture.
 
     Subject to the restrictions discussed under "Limitations on Issuance of
Bearer Securities," payment of principal of (and premium, if any) and any
interest on Securities registered in the name of or held by a Depositary or its
nominee will be made to such Depositary or its nominee, as the case may be, as
the registered owner or the holder of the Global Security representing such
Securities. None of the Company, the Trustee for such Securities, any Paying
Agent, any Authenticating Agent or the Security Registrar for such Securities
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests in a Global
Security representing such Securities or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. (Section
307)
 
     The Company expects that the Depositary for Securities, upon receipt of any
payment of principal of (or premium, if any) or any interest on a definitive
Global Security representing such Securities, will credit immediately
participants' accounts with payments in amounts proportionate to their
respective holdings in principal amount of beneficial interest in such Global
Security as shown on the records of such Depositary. The Company also expects
that payments by participants to owners of beneficial interests in such Global
Security held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name".
Such payments will be the responsibility of such participants. Receipt by owners
of beneficial interests in a temporary Global Security of payments of principal
of (or premium, if any) or any interest on such Global Security will be subject
to the restrictions discussed under "Limitation on Issuance of Bearer
Securities."
 
     Unless and until it is exchanged in whole for Securities in definitive
form, a Global Security may not be transferred except as a whole by the
Depositary for such Global Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor of such
Depositary or a nominee of such successor. (Section 312) If a Depositary for
Securities of any series is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by the Company within
ninety days, the Company will issue Securities of such series in like tenor and
terms in definitive registered form in exchange for the Global Security or
Global Securities representing all such Securities. Further, an owner of a
beneficial interest in a Global Security representing Securities of a series
may, on terms acceptable to the Company and the Depositary for such Global
Security, receive Securities of such series in definitive registered form. In
addition, the Company may at any time and in its sole discretion determine not
to have any Securities of a series represented by Global Securities and, in such
event, will issue Securities of such series in like tenor and terms in
definitive registered form in exchange for the Global Security or Global
Securities representing all such Securities. In any such instance, an owner of a
beneficial interest in a Global Security will be entitled to
 
                                        9
<PAGE>   69
 
physical delivery in definitive form of Securities of the series represented by
such Global Security equal in aggregate principal amount to such beneficial
interest and to have such Securities registered in the name of the owner of such
beneficial interest. (Section 312)
 
   
     If so specified in an applicable Prospectus Supplement, all or any portion
of the Securities of a series that are issuable as Bearer Securities initially
will be represented by one or more temporary Global Securities, with one or more
Coupons or without Coupons, to be deposited with a common depository in London
for Morgan Guaranty Trust Company of New York, Brussels Office, as operator of
the Euroclear System ("Euroclear") and Cedel Bank societe anonyme ("Cedel") for
credit to the respective accounts of the beneficial owners of such Securities
(or to such other accounts as they may direct). On and after the exchange date
determined as provided in any such temporary Global Security and described in an
applicable Prospectus Supplement, each such temporary Global Security will be
exchangeable for a like aggregate principal amount of definitive Securities in
like tenor and terms in bearer form, registered form or definitive global bearer
form, or any combination thereof, as specified in an applicable Prospectus
Supplement. No Bearer Security (including a Global Security in definitive bearer
form) delivered in exchange for a portion of a temporary Global Security shall
be mailed or otherwise delivered to any location in the United States (as
defined under "Limitations on Issuance of Bearer Securities") in connection with
such exchange. (Sections 303 and 304)
    
 
   
     Unless otherwise specified in an applicable Prospectus Supplement,
definitive Securities in respect of any portion of a temporary Global Security
will only be delivered, and interest in respect of any portion of a temporary
Global Security payable in respect of an Interest Payment Date occurring prior
to the issuance of definitive Securities will only be paid, upon delivery of a
certificate signed by Euroclear or Cedel, as the case may be, with respect to
the portion of the temporary Global Security held for the account of the
beneficial owner in the form required by the applicable Indenture. Such
certificate must be dated no earlier than the exchange date or such Interest
Payment Date, as the case may be, and must be based on statements provided to
Euroclear or Cedel, as applicable, by its account holders who are beneficial
owners of interests in such temporary Global Security to the effect that such
portion is beneficially owned (i) by a person that is not a United States person
or (ii) by or through a qualifying financial institution in compliance with
applicable Treasury regulations.
    
 
   
     If any Securities of a series are issuable in definitive global form, the
applicable Prospectus Supplement will describe the circumstances, if any, under
which beneficial owners of interests in any such definitive Global Security may
exchange such interests for Securities of such series and of like tenor, terms
and principal amount in any authorized form and denomination. No Bearer Security
delivered in exchange for a portion of a definitive Global Security shall be
mailed or otherwise delivered to any location in the United States in connection
with such exchange. (Section 305) A Person having a beneficial interest in a
definitive Global Security, except with respect to payment of principal of (and
premium, if any) and any interest on such definitive Global Security, will be
treated as a Holder of such principal amount of Outstanding Securities
represented by such definitive Global Security as shall be specified in a
written statement of the Holder of such definitive Global Security, or, in the
case of a definitive Global Security in bearer form, of Euroclear or Cedel,
which is produced to the Trustee by such Person. (Section 203) Principal of (and
premium, if any) and any interest on a definitive Global Security will be
payable in the manner described in the applicable Prospectus Supplement.
    
 
CERTAIN RESTRICTIVE PROVISIONS
 
     The Senior Indenture relating to Offered Securities to be issued on a
parity with other senior indebtedness of the Company provides that, with certain
limited exceptions, the Company will not, nor will it permit any Restricted
Subsidiary (as defined in the Senior Indenture) to, pledge as security for any
loan the capital stock or indebtedness of any Restricted Subsidiary or create,
incur, assume or permit to exist any lien on any property or asset of the
Company. (Section 1008) Such provisions shall apply to all such Offered
Securities unless the applicable Prospectus Supplement expressly states
otherwise.

<PAGE>   70
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     Each Indenture provides that the Company, without the consent of any
Holders of Securities, may consolidate with or merge into any other corporation
or transfer or lease its assets substantially as an entirety to any Person or
may acquire or lease the assets of any Person substantially as an entirety or
may permit any corporation to merge into the Company provided that: (i) the
successor is a corporation organized under the laws of any domestic
jurisdiction; (ii) the successor corporation, if other than the Company, assumes
the Company's obligations under such Indenture and the Securities issued
thereunder; (iii) immediately after giving effect to the transaction, no Event
of Default and no event that, after notice or lapse of time, or both, would
become an Event of Default, shall have occurred and be continuing; and (iv)
certain other conditions are met. (Section 801)
 
MODIFICATION OF THE INDENTURES
 
     Each Indenture provides that the Company and the Trustee thereunder may,
without the consent of any Holders of Securities, enter into supplemental
indentures for the purposes, among other things, of adding to the Company's
covenants, adding additional Events of Default, establishing the form or terms
of Securities or, provided such action shall not adversely affect the interests
of the Holders of any series of Securities in any material respect, curing
ambiguities or inconsistencies in such Indenture or making other provisions.
(Section 901)
 
     Each Indenture contains provisions permitting the Company, with the consent
of the Holders of not less than 66 2/3% in principal amount of the Outstanding
Securities of each affected series, to execute supplemental indentures adding
any provisions to or changing or eliminating any of the provisions of such
Indenture or modifying the rights of the Holders of the Securities of such
series, except that no such supplemental indenture may, without the consent of
the Holders of all the Outstanding Securities affected thereby, among other
things: (i) change the maturity of the principal of, or any installment of
principal of or interest on, any of the Securities; (ii) reduce the principal
amount thereof (or any premium thereon) or the rate of interest, if any,
thereon; (iii) reduce the amount of the principal of Original Issue Discount
Securities payable on any acceleration of maturity; (iv) change the currency,
currencies, composite currency or composite currencies in which any of the
Securities or any premium or interest thereon is payable; (v) change any
obligation of the Company to maintain an office or agency in the places and for
the purposes required by such Indenture; (vi) impair the right to institute suit
for the enforcement of any payment due on any Securities on or after their
applicable maturity date; (vii) reduce the percentage in principal amount of the
Outstanding Securities of any series the consent of the Holders of which is
required for any such supplemental indenture or for any waiver of compliance
with certain provisions of, or of certain defaults under, such Indenture; or
(viii) with certain exceptions, modify the provisions for the waiver of certain
covenants and defaults and any of the foregoing provisions. (Section 902)
 
WAIVER OF CERTAIN COVENANTS
 
     The Senior Indenture provides that the Company will not be required to
comply with certain restrictive covenants (including those described above under
"Certain Restrictive Provisions") if the Holders of not less than 66 2/3% in
principal amount of each series of Outstanding Securities affected thereby waive
compliance with such restrictive covenants. (Section 1005)
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     An Event of Default in respect of any series of Securities (unless it is
either inapplicable to a particular series or has been modified or deleted with
respect to any particular series) is defined in each Indenture to be: (i) a
default for 30 days in the payment of any installment of interest upon any of
the Securities of such series when due; (ii) a default in the payment of
principal of (or premium, if any, on) any of the Securities of such series when
due; (iii) a default in the deposit of any sinking fund payment when the same
becomes due by the terms of the Securities of such series; (iv) a default in the
performance, or breach, of any other covenants or warranties of the Company in
the applicable Indenture which shall not have been remedied for a period of
 
                                       11
<PAGE>   71
 
60 days after notice from the Trustee thereunder or the Holders of not less than
25% in principal amount of the Outstanding Securities of such series; (v)
certain events of bankruptcy, insolvency or reorganization of the Company; and
(vi) such other events as may be specified for such series. (Section 501)
 
     Each Indenture provides that if an Event of Default specified therein in
respect of any series of Outstanding Securities issued under such Indenture
shall have occurred and be continuing, either the Trustee thereunder or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of such series may declare the principal (or, if such Securities are Original
Issue Discount Securities, such portion of the principal amount as may be
specified by the terms of such Securities) of all of the Outstanding Securities
of such series to be immediately due and payable. (Section 502)
 
   
     Each Indenture provides that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee thereunder, or exercising any trust or power conferred on such
Trustee, with respect to the Securities of such series; provided that such
Trustee may act in any way that is not inconsistent with such directions and may
decline to act if any such direction is contrary to law or to such Indenture or
would involve such Trustee in personal liability. (Section 512)
    
 
Each Indenture provides that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all of the Outstanding Securities of such series waive any past
default under the applicable Indenture with respect to such series and its
consequences, except a default (i) in the payment of the principal of (or
premium, if any) or any interest on any of the Securities of such series or (ii)
in respect of a covenant or provision of such Indenture which, under the terms
of such Indenture, cannot be modified or amended without the consent of the
Holders of all of the Outstanding Securities of such series affected thereby.
(Section 513)
 
     Each Indenture contains provisions entitling the Trustee thereunder,
subject to the duty of such Trustee during an Event of Default in respect of any
series of Securities to act with the required standard of care, to be
indemnified by the Holders of the Securities of such series before proceeding to
exercise any right or power under such Indenture at the request of the Holders
of the Securities of such series. (Sections 601 and 603)
 
     Each Indenture provides that the Trustee thereunder will, within 90 days
after the occurrence of a default in respect of any series of Securities, give
to the Holders of the Securities of such series notice of all uncured and
unwaived defaults known to it; provided, however, that, except in the case of a
default in the payment of the principal of (or premium, if any) or any interest
on, or any sinking fund installment with respect to, any of the Securities of
such series, such Trustee will be protected in withholding such notice if it in
good faith determines that the withholding of such notice is in the interest of
the Holders of the Securities of such series; and provided, further, that such
notice shall not be given until at least 30 days after the occurrence of an
Event of Default regarding the performance, or breach, of any covenant or
warranty of the Company under such Indenture other than for the payment of the
principal of (or premium, if any) or any interest on, or any sinking fund
installment with respect to, any of the Securities of such series. The term
default for the purpose of this provision only means any event that is, or after
notice or lapse of time, or both, would become, an Event of Default with respect
to the Securities of such series. (Section 602)
 
     Each Indenture requires the Company to file annually with the Trustee
thereunder a certificate, executed by an officer of the Company, indicating
whether the Company is in default under such Indenture. (Section 1004)
 
MEETINGS
 
     Each Indenture contains provisions for convening meetings of the Holders of
Securities of a series if Securities of that series are issuable as Bearer
Securities to make, give or take any request, demand, authorization, direction,
notice, consent, waiver or other action that may be made, given or taken by such
Holders pursuant to such Indenture. (Section 1301). A meeting may be called at
any time by the Trustee under the applicable Indenture, and also, upon request,
by the Company or the Holders of at least 10% in principal amount of the
Outstanding Securities of such series, in any such case upon notice given in
 
                                       12
<PAGE>   72
 
accordance with "Notices" below. (Section 1302) Persons entitled to vote a
majority in principal amount of the Outstanding Securities of a series shall
constitute a quorum at a meeting of Holders of Securities of such series;
provided, however, that if any action is to be taken at such meeting with
respect to a consent or waiver which is required to be given by the Holders of
not less than 66 2/3% in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote 66 2/3% in principal amount of the
Outstanding Securities of such series shall constitute a quorum. In the absence
of a quorum, (i) a meeting called by the Company or the Trustee shall be
adjourned for a period of not less than 10 days, and in the absence of a quorum
at any such adjourned meeting, the meeting shall be further adjourned for a
period of not less than 10 days and (ii) a meeting called by the Holders shall
be dissolved. Any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which may be made, given or
taken by the Holders of a specified percentage in principal amount of
Outstanding Securities of a series may be adopted at a meeting or adjourned
meeting duly reconvened at which a quorum is present by the affirmative vote of
the Holders of such specified percentage in principal amount of the Outstanding
Securities of that series. Any resolution passed or decision taken at any
meeting of Holders of Securities of any series duly held in accordance with the
applicable Indenture will be binding on all Holders of Securities of that series
and of the related Coupons whether or not present or represented at the meeting.
With respect to any consent, waiver or other action which the applicable
Indenture expressly provides may be given by the Holders of a specified
percentage of Outstanding Securities of all series affected thereby (acting as
one class), only the principal amount of Outstanding Securities of any series
represented at a meeting or adjourned meeting duly reconvened at which a quorum
is present as aforesaid and voting in favor of such action shall be counted for
purposes of calculating the aggregate principal amount of Outstanding Securities
of all series affected thereby favoring such action. (Section 1304)
 
NOTICES
 
     Except as otherwise provided in each Indenture, notices to Holders of
Bearer Securities will be given by publication at least once in a daily
newspaper in The City of New York and London and in such other city or cities as
may be specified in such Bearer Securities and will be mailed to such Persons
whose names and addresses were previously filed with the Trustee under the
applicable Indenture within the two preceding years, within the time prescribed
for the giving of such notice. Notices to Holders of Registered Securities will
be given by mail to the addresses of such Holders as they appear in the Security
Register, within the time prescribed for the giving of such notice. (Section
106)
 
TITLE
 
     Title to any Bearer Securities (including Bearer Securities that are Global
Securities) and any Coupons appertaining thereto will pass by delivery. The
Company, the appropriate Trustee and any agent of the Company or such Trustee
may treat the Holder of any Bearer Security, the Holder of any Coupon and the
registered owner of any Registered Security as the absolute owner thereof
(whether or not such Security or Coupon shall be overdue and notwithstanding any
notice to the contrary) for the purpose of making payment and for all other
purposes. (Section 308)
 
REPLACEMENT OF SECURITIES AND COUPONS
 
     Any mutilated Security and any Security with a mutilated Coupon
appertaining thereto will be replaced by the Company at the expense of the
Holder upon surrender of such mutilated Security or Security with a mutilated
Coupon to the appropriate Trustee. Securities or Coupons that become destroyed,
stolen or lost will be replaced by the Company at the expense of the Holder upon
delivery to the appropriate Trustee of evidence of the destruction, loss or
theft thereof satisfactory to the Company and such Trustee; in the case of any
Coupon which becomes destroyed, stolen or lost, such Coupon will be replaced
(upon surrender to the appropriate Trustee of the Security with all appurtenant
Coupons not destroyed, stolen or lost) by issuance of a new Security in exchange
for the Security to which such Coupon appertains. In the case of a destroyed,
lost or stolen Security or Coupon, an indemnity satisfactory to the appropriate
Trustee and the Company may be
 
                                       13
<PAGE>   73
 
required at the expense of the Holder of such Security or Coupon before a
replacement Security will be issued. (Section 306)
 
DEFEASANCE
 
     Unless the Prospectus Supplement relating to the Offered Securities
provides otherwise, the Company at its option (i) will be Discharged (as such
term is defined in the applicable Indenture) from any and all obligations in
respect of the Offered Securities (except for certain obligations to register
the transfer or exchange of Securities, replace stolen, lost or mutilated
Securities and Coupons, maintain paying agencies and hold moneys for payment in
trust) or (ii) need not comply with certain restrictive covenants of the
applicable Indenture (including those described above under "Certain Restrictive
Provisions"), if there is deposited with the Trustee money and/or (a) in the
case of Securities and Coupons denominated in U.S. dollars, U.S. Government
Obligations (as defined in the applicable Indenture), or (b) in the case of
Securities and Coupons denominated in a foreign or composite currency, Foreign
Government Securities (as defined in the applicable Indenture), which in each
case through the payment of interest thereon and principal thereof in accordance
with their terms will provide money, in an amount sufficient to pay in the
currency, currencies, composite currency or composite currencies in which the
Offered Securities are payable all the principal of, and interest on, the
Offered Securities on the dates such payments are due in accordance with the
terms of the Offered Securities. Among the conditions to the Company's
exercising any such option, the Company is required to deliver to the
appropriate Trustee an opinion of counsel to the effect that the deposit and
related defeasance would not cause the Holders of the Offered Securities to
recognize income, gain or loss for United States Federal income tax purposes and
that the Holders will be subject to United States Federal income tax in the same
amounts, in the same manner and at the same times as would have been the case if
such deposit and related defeasance had not occurred. (Sections 401 and 403)
 
SUBORDINATION
 
     The payment of the principal of (and premium, if any) and any interest on
the Subordinated Securities, including sinking fund payments, is subordinated in
right of payment, to the extent and in the manner set forth in the Subordinated
Indenture, to the prior payment in full of all Superior Indebtedness. (Section
1401) Superior Indebtedness is defined as (i) the principal of, premium, if any,
and accrued and unpaid interest on (a) indebtedness of the Company for money
borrowed, whether outstanding on the date of execution of the Subordinated
Indenture or thereafter created, incurred or assumed, (b) guarantees by the
Company of indebtedness for money borrowed by any other person, whether
outstanding on the date of execution of the Subordinated Indenture or thereafter
created, incurred or assumed, (c) indebtedness evidenced by notes, debentures,
bonds or other instruments of indebtedness for the payment of which the Company
is responsible or liable, by guarantees or otherwise, whether outstanding on the
date of execution of the Subordinated Indenture or thereafter created, incurred
or assumed, and (d) obligations of the Company under any agreement to lease, or
any lease of, any real or personal property, whether outstanding on the date of
execution of the Subordinated Indenture or thereafter created, incurred or
assumed, (ii) any other indebtedness, liability or obligation, contingent or
otherwise, of the Company and any guarantee, endorsement or other contingent
obligation of the Company in respect of any indebtedness, liability or
obligation, whether outstanding on the date of execution of the Subordinated
Indenture or thereafter created, incurred or assumed, and (iii) modifications,
renewals, extensions and refundings of any such indebtedness, liabilities,
obligations or guarantees; unless, in the instrument creating or evidencing the
same or pursuant to which the same is outstanding, it is provided that such
indebtedness, liabilities, obligations or guarantees, or such modification,
renewal, extension or refunding thereof, are not superior in right of payment to
the Subordinated Securities; provided, however, that Superior Indebtedness will
not be deemed to include, and the Subordinated Securities will rank equal in
right of payment to, the Company's 7 3/4% Subordinated Notes due 2002, and all
other such subordinated securities, including but not limited to the Medium-Term
Subordinated Notes, Series B, and the Medium-Term Subordinated Notes, Series D,
of the Company, or any obligation of the Company to any subsidiary. (Sections
101, 1401 and 1408) The Subordinated Indenture and the Subordinated Securities
do not contain any covenants or other provisions that would limit the issuance
of additional Superior Indebtedness.
 
                                       14
<PAGE>   74
 
     No payment by the Company on account of principal of (or premium, if any)
or any interest on the Subordinated Securities, including sinking fund payments,
may be made if any default or event of default with respect to any Superior
Indebtedness shall have occurred and be continuing and written notice thereof
shall have been given to the Trustee by the Company or to the Company and the
Trustee by the holders of at least 10% in principal amount of any kind or
category of any Superior Indebtedness (or a representative or trustee on their
behalf). Upon any acceleration of the principal due on the Subordinated
Securities or any payment or distribution of assets of the Company to creditors
upon any dissolution, winding up, liquidation or reorganization, whether
voluntary or involuntary or in bankruptcy, insolvency, receivership or other
proceedings, all principal of (and premium, if any) and interest due or to
become due on all Superior Indebtedness must be paid in full before the holders
of Subordinated Securities are entitled to receive or retain any payment (other
than shares of stock or subordinated indebtedness provided by a plan of
reorganization or adjustment which does not alter the rights of holders of
Superior Indebtedness). Subject to the payment in full of all Superior
Indebtedness, the holders of the Subordinated Securities are to be subrogated to
the rights of the holders of Superior Indebtedness to receive payments or
distributions of assets of the Company applicable to Superior Indebtedness until
the Subordinated Securities are paid in full. (Section 1402) By reason of such
subordination, in the event of insolvency, creditors of the Company who are
holders of Superior Indebtedness, as well as certain general creditors of the
Company, may recover more, ratably, than the holders of the Subordinated
Securities.
 
   
     The Company's rights and the rights of its creditors (including holders of
Senior Securities and Subordinated Securities) to participate in any
distribution of assets of any subsidiary of the Company upon its liquidation or
reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized. Also, dividend
payments and advances to the Company by PaineWebber and certain other
subsidiaries of the Company are restricted by the provisions of the net capital
rules of the Commission and the NYSE and covenants in various loan agreements.
The operations of the Company are conducted through its subsidiaries and,
therefore, the Company is dependent upon the earnings and cash flow of its
subsidiaries to meet its obligations, including obligations under the Senior
Securities and Subordinated Securities. The Senior Securities and Subordinated
Securities will be effectively subordinated to all indebtedness of the Company's
subsidiaries. As of September 30, 1996, the aggregate amount of indebtedness of
the Company's subsidiaries (such indebtedness consisting of short-term
borrowings and excluding short-term and long-term borrowings owed directly or
indirectly to the Company or another subsidiary) to which holders of the Senior
Securities and Subordinated Securities would have been structurally subordinated
was approximately $405 million.
    
 
GOVERNING LAW
 
     The Indenture, the Securities and the Coupons will be governed by, and

                                 ERISA MATTERS
 
     The Company, PaineWebber, PaineWebber International and other affiliates of
the Company may each be considered a "party in interest" (within the meaning of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) or a
"disqualified person" (within the meaning of Section 4975 of the Internal
Revenue Code of 1986, as amended (the "Code")) with respect to many employee

(including individual retirement arrangements and other plans described in
Section 4975(e)(1) of the Code) and with respect to which the Company,
PaineWebber, PaineWebber International or any other affiliate of the Company is
a service provider (or otherwise is a party in interest or a disqualified
person) may constitute or result in a prohibited transaction under ERISA or
Section 4975 of the Code, unless such Securities are acquired pursuant to and in
accordance with an applicable exemption. Any pension or other employee benefit
plan proposing to acquire any Securities should consult with its counsel.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Securities being offered hereby (i) directly to
one or more purchasers, (ii) through agents designated from time to time, (iii)
through underwriters or dealers or a group of underwriters. The applicable
Prospectus Supplement will set forth the terms of the offering of any Offered
Securities, including the name or names of any underwriters, the purchase price
of the Offered Securities and the proceeds to the Company from such sale, any
underwriting discounts and other items constituting underwriters' compensation,
any initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers and any securities exchanges on which the Offered
Securities may be listed. If a bidding or auction process is utilized, it will
be described in the Prospectus Supplement.
 
     If underwriters are used in the sale, Offered Securities will be acquired
by the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The Offered
Securities may be offered to the public either through underwriting syndicates
represented by managing underwriters or by underwriters without a syndicate.
Unless otherwise set forth in the applicable Prospectus Supplement, the
obligations of the underwriters to purchase the Offered Securities will be
subject to certain conditions precedent, and the underwriters will be obligated
to purchase all of the Offered Securities if any are purchased. Any initial
public offering price and any discounts or concessions allowed or reallowed or
paid to dealers may be changed from time to time.
 
     Offered Securities may be sold directly by the Company or through agents
designated by the Company from time to time. Any agent involved in the offer or
sale of Offered Securities will be named, and any commissions payable by the
Company to such agents will be set forth, in the applicable Prospectus
Supplement. Unless otherwise indicated in the applicable Prospectus Supplement,
any such agent will be acting on a best efforts basis for the period of its
appointment.
 
     If so indicated in the applicable Prospectus Supplement, the Company will
authorize agents, underwriters or dealers to solicit offers by certain specified
institutions to purchase Offered Securities from the Company at the public
offering price set forth in such Prospectus Supplement pursuant to delayed
delivery contracts providing for payment and delivery on a specified date in the
future. Such contracts will be subject only to those conditions set forth in the
applicable Prospectus Supplement and such Prospectus Supplement will set forth
the commission payable for the solicitation of such contracts.
 
     Any underwriters, dealers or agents participating in the distribution of
Securities may be deemed to be underwriters and any discounts or commissions
received by them on the sale or resale of Offered Securities may be deemed to be
underwriting discounts and commissions under the Securities Act. Agents and
underwriters may be entitled under agreements entered into with the Company to
indemnification by the Company against certain liabilities, including
liabilities under the Securities Act, or to contribution with respect to
payments which the agents or underwriters may be required to make in respect
thereof. Agents and underwriters may be customers of, engage in transactions
with, or perform services for the Company in the ordinary course of business.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Company and each underwriter, dealer and agent participating in the distribution
of any Offered Securities which are issuable in bearer form will agree that, in
connection with the original issuance of any Bearer Security and during the
period ending 40 days after the date of original issuance of such Bearer
Security, they will not offer, sell or deliver such Bearer Security, directly or
indirectly, to a United States person or to any person within the United States,
 
                                       16
<PAGE>   76
 
except to the extent permitted under applicable Treasury regulations. Any other
restrictions on the offer or sale of Offered Securities in or from jurisdictions
other than the United States or within the United States will be set forth in
the applicable Prospectus Supplement.
 
     All Offered Securities will be a new issue of securities with no
established trading market. Certain agents through whom, and underwriters to
whom, Offered Securities are sold by the Company for public offering and sale
may make a market in such Offered Securities, but such agents and underwriters
will not be obligated to do so and may discontinue any market making at any time
without notice. No assurance can be given as to the liquidity of the trading
market for any Offered Securities.
 
     PaineWebber, PaineWebber International or one or more other affiliates of
the Company may participate in distributions of the Offered Securities. All
distributions of the Offered Securities will conform to the requirements set
forth in Rule 2720 of the Conduct Rules of the NASD.
 
                  LIMITATIONS ON ISSUANCE OF BEARER SECURITIES
 
     In compliance with United States Federal income tax laws and regulations,
in general a Bearer Security may not be offered, sold or delivered, directly or
indirectly, to a United States person or to any person within the United States
in connection with the original issuance of such Bearer Security or during the
period ending 40 days after the date of original issuance of such Bearer
Security. However, offers or sales can be made during this period to certain
institutions, including certain international organizations and foreign branches
of U.S. financial institutions (a "qualifying financial institution"), that
satisfy the requirements prescribed by applicable Treasury regulations. In
addition, sales can be made to a United States person acquiring a Bearer
Security through a qualifying financial institution in compliance with
applicable Treasury regulations. Definitive Bearer Securities will not be
delivered to a holder, however, unless the beneficial owner of the Securities
has complied with the certification requirements described above under
"Description of Securities--Global Securities" or, in any event, within the
United States.
 
     Bearer Securities will bear the following legend on their face and on any
Coupons which may be detached therefrom or, if the obligation is evidenced by a
book entry, in the book of record in which the book entry is made: "Any United
States person who holds this obligation will be subject to limitations under the
United States income tax laws, including the limitations provided in Sections
165(j) and 1287(a) of the United States Internal Revenue Code". The Sections
referred to in such legend provide that, with certain exceptions, a United
States taxpayer who holds a Bearer Security will not be allowed to deduct any
loss with respect to, and will not be eligible for capital gain treatment with
respect to any gain realized on, the sale, exchange, redemption or other
disposition of such Bearer Security.
 
     As used herein, "United States person" means any citizen or resident of the
United States, any corporation, partnership or other entity created or organized
in or under the laws of the United States or any political subdivision thereof,
or any estate or trust the income of which is subject to United States Federal
income taxation regardless of its source, and "United States" means the United
States of America and its possessions (including Puerto Rico, the U.S. Virgin
Islands, Guam, American Samoa and the Northern Mariana Islands).
 
                                 LEGAL MATTERS
 
   
     The validity of the Securities offered hereby will be passed upon for the
Company by its General Counsel, Theodore A. Levine, and for the agents or
underwriters, if any, by Cravath, Swaine & Moore, 825 Eighth Avenue, New York,
New York. Mr. Levine beneficially owns, or has rights to acquire under an
employee benefit plan of the Company, an aggregate of less than 1% of the common
stock of the Company. Cravath, Swaine & Moore acts from time to time as legal
counsel to the Company and its subsidiaries on the various matters.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
   
     Section 102 of the General Corporation Law of the State of Delaware gives
corporations the power to eliminate or limit the personal liability of directors
under certain circumstances. Section 145 of the General Corporation Law of the
State of Delaware gives corporations the power to indemnify directors and
officers under certain circumstances.
    
 
   
     Article IX of the Restated Certificate of Incorporation (relating to the
elimination of personal liability of directors of the Company) of Paine Webber
Group Inc. is hereby incorporated by reference to Exhibit 3.1 hereto. Article
VII of Paine Webber Group Inc.'s By-Laws (relating to indemnification of
directors and officers of the Company) is hereby incorporated by reference to
Exhibit 3.2 hereto.
    
 
   
     The Company also maintains directors and officers liability and corporate
reimbursement insurance which provides for coverage against loss arising from
claims made against directors and officers in their capacity as such. The
general scope of coverage is any breach of duty, neglect, error, misstatement,
misleading statement or omission. Such policy does not exclude liabilities under
the Securities Act of 1933. The Company also maintains fiduciary liability
insurance for losses in connection with claims made against directors of
officers for violation of any of the responsibilities, obligations or duties
imposed upon fiduciaries under the Employee Retirement Income Security Act of
1974.
    
 
     The indemnification provisions (relating to indemnification of, among
others, controlling persons, directors and officers of the Company against
certain liabilities) contained in the proposed forms of Underwriting Agreement
are hereby incorporated by reference to Exhibits 1.1 and 1.2 hereto.

Item 17. UNDERTAKINGS.
    
 
     The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement;
 
   
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
    
 
   
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered
    
 
                                      II-1
<PAGE>   79
 
   
        (if the total dollar value of securities offered would not exceed that
        which was registered) and any deviation from the low or high end of the
        estimated maximum offering range may be reflected in the form of
        prospectus filed with the Commission pursuant to Rule 424(b) if, in the
        aggregate, the changes in volume and price represent no more than a 20%
        change in the maximum aggregate offering price set forth in the
        "Calculation of Registration Fee" table in the effective registration
        statement; and
    
 
   
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
    
 
   
     provided, however, that the undertakings set forth in paragraph (i) and
     (ii) above do not apply if the information required to be included in a
     post-effective amendment by those paragraphs is contained in periodic
     reports filed by the registrants pursuant to Section 13 or Section 15(d) of
     the Securities Exchange Act of 1934 that are incorporated by reference in
     this registration statement.
    
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
   
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
    
 
   
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
    
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 15 above or otherwise,
the registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1993 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
   
     The undersigned Registrants hereby undertake that:
    
 
   
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of the
     registration statement as of the time it was declared effective.
    
 
   
          (2) For the purposes of determining any liability under the Securities
     Act of 1933 each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

agreements of the Trust and the Company herein contained and subject to all the
terms and conditions of this Agreement, the Trust agrees to sell to each
Underwriter, and each Underwriter, severally and not jointly, agrees to purchase
from the Trust, at a purchase price of $25.00 per Preferred Security, the number
of Firm Securities set forth opposite the name of such Underwriter in Schedule

Preferred Security as the Underwriters shall pay for the Firm Securities plus
any accrued and unpaid distributions on the Option Securities as of the Option
Closing Date (as defined below). The Option may be exercised only to cover
over-allotments in the sale of the Firm Securities by the Underwriters and may

hereunder, and in view of the fact that the proceeds of the sale of the
Preferred Securities will be used by the Trust to purchase the Debentures of the

Such payments shall be made at 10:00 a.m., New York City time, on the [third]
[fourth] business day after the date on which the first bona fide offering of
the Firm Securities to the public is made by the Underwriters or at such time
on such other date, not later than seven business days after such date, as may
be agreed upon by the Trust and the Representative[s] (such date is hereinafter
referred to as the "Closing Date").

harmless from any and all liabilities with respect to or resulting from any
failure or delay in paying Federal and state stamp and other transfer taxes, if
any, which may be payable or determined to be payable in connection with


                                        3

governmental body, domestic or foreign, wherein an unfavorable ruling, decision
or finding would reasonably be expected to have a Material Adverse Effect.

              (y)  Each of the Trust and the Company and each of its
Subsidiaries has, and at the Closing Date will have, (i) all governmental
licenses, permits, consents, orders, approvals and other authorizations
necessary to carry on its business as contemplated in the Prospectus, (ii)
complied in all respects with all laws, regulations and orders applicable to it
or its business and (iii) performed all obligations required to be performed by
it, and is not, and at the Closing Date will not be, in default, under any
indenture, mortgage, deed of trust, voting trust agreement, loan agreement,
bond, debenture, note agreement, lease, contract or other agreement or
instrument (collectively, a "contract or other agreement") to which it is a
party or by which its property is bound or affected; except in the case of (i),
(ii) or (iii) above, for such failures to possess, comply or perform as would
not have a Material Adverse Effect. To the best knowledge of each of the Trust
and the Company and each of its Subsidiaries, no other party under any contract
or other agreement to which it is a party is in material default thereunder.
None of the Trust, the Company nor any of its Subsidiaries is, nor at the
Closing Date will any of them be, in violation of its respective Declaration,
charter or by-laws.

              (z)  No consent, approval, authorization or order of, or any
filing or declaration with, any court or governmental agency or body is required
in connection with the authorization, issuance, transfer, sale or delivery of
the Trust Securities by the Trust or the Guarantee and the Debentures by the
Company, in connection with the execution, delivery and performance of this
Agreement by the Trust and the Company or in connection with the taking by the
Trust or the Company of any action contemplated hereby and in the Indenture, the
Guarantee, the Preferred Securities and the Common Securities, except such as
have been obtained under the Act, the Rules and Regulations, the Trust Indenture
Act and the Trust Indenture Act Rules and Regulations and such as may be
required under state securities or Blue Sky laws or the by-laws and rules of the
National Association of Securities Dealers, Inc. (the "NASD") in connection with
the purchase and distribution by the Underwriters of the Preferred Securities
and such as may be required to be obtained subsequent to the Closing Date in
connection with the performance by the Trust and the Company of the actions
contemplated to be taken by each pursuant to such agreements and instruments.

              (aa) The Company and each of its Subsidiaries has valid,
subsisting and enforceable leases for the properties described in the
Registration Statement and the Prospectus as leased by it, with such exceptions
as are not material and do not materially interfere with the use made and
proposed to be made of such properties by the Company and such Subsidiaries.

              (ab) There is no document or contract of a character required to
be described in the Registration Statement or the Prospectus or to be filed as
an exhibit to the Registration Statement which is not described or filed as
required. All such contracts to which the Trust or the Company or any Subsidiary
is a party have been duly authorized, executed and delivered by the Trust or the
Company or such Subsidiary, constitute valid and binding agreements of the Trust
or the Company or such Subsidiary and are enforceable against the Trust or the
Company or such Subsidiary in accordance with the terms thereof (subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and other similar laws affecting creditors' rights generally from time
to time in effect and to general principles of equity, including, without
limitation, concepts of materiality, reasonableness, good faith and fair
dealing, regardless of whether considered in a proceeding in equity or at law).

              (ac) No statement, representation, warranty or covenant made by
the Trust or the Company in this Agreement, the Indenture or the Declaration or
made in any certificate or document required by this Agreement to be delivered
to the Representative[s] was or will be, when made, inaccurate, untrue or
incorrect.

              (ad) Neither the Company nor the Trust nor any of their respective
directors, officers, trustees or controlling persons has taken, directly or
indirectly, any action designed, or which might reasonably be expected, to cause
or result, under the Act or


                                       12
<PAGE>   13
otherwise, in, or which has constituted, stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Preferred Securities.

              (ae) At the Closing Date, the Preferred Securities will be duly
authorized for listing by the New York Stock Exchange, Inc. (the "NYSE") upon
official notice of issuance.

              (af) Neither the Trust, the Company nor any of its Subsidiaries is
involved in any material labor dispute nor, to the knowledge of the Trust or the
Company, is any such dispute threatened.

              (ag) The Company and its Subsidiaries own, or are licensed or
otherwise have the full right to use, all material trademarks and trade names
which are used in or necessary for the conduct of their respective businesses as
described in the Prospectus. No claims have been asserted by any person to the
use of any such trademarks or trade names or challenging or questioning the
validity or effectiveness of any such trademark or trade name except such claims
as would not reasonably be expected to have a Material Adverse Effect. The use,
in connection with the business and operations of the Company and its
Subsidiaries of such trademarks and trade names does not, to the Company's
knowledge, infringe on the rights of any person except such infringements as
would not reasonably be expected to have a Material Adverse Effect.

              (ah) Neither the Trust, the Company nor any of its Subsidiaries
nor, to the Trust's or the Company's knowledge, any employee or agent of the
Trust, the Company or any Subsidiary has made any payment of funds of the Trust,
the Company or any Subsidiary or received or retained any funds in violation of
any law, rule or regulation or of a character required to be disclosed in the
Prospectus.

         4.   Agreements of the Trust and the Company. The Trust and the
Company, jointly and severally, agree with the several Underwriters as follows:

              (a)  The Company and the Trust will not, either prior to the
Effective Date or thereafter during such period as a prospectus is required by
law to be delivered in connection with sales of the Offered Securities by an
Underwriter or dealer, file any amendment or supplement to the Registration
Statement or the Prospectus, unless a copy thereof shall first have been
submitted to the Representative[s] within a reasonable period of time prior to
the filing thereof and the Representative[s] shall not have objected thereto in
good faith.

              (b)  The Trust and the Company will use their best efforts to
cause the Registration Statement to become effective, and will notify the
Representative[s] promptly, and will confirm such advice in writing, (1) when
the Registration Statement has become effective and when any post-effective
amendment thereto becomes effective, (2) of any request by the Commission for
amendments or supplements to the Registration Statement


                                       13
<PAGE>   14
or the Prospectus or for additional information, (3) of the issuance by the
Commission of any Stop Order suspending the effectiveness of the Registration
Statement or the initiation of any proceedings for that purpose or the threat
thereof, (4) of the happening of any event during the period mentioned in the
second sentence of Section 4(e) that in the judgment of the Trust or the Company
makes any statement made in the Registration Statement or the Prospectus untrue
or that requires the making of any changes in the Registration Statement or the
Prospectus in order to make the statements therein, in the light of the
circumstances in which they are made, not misleading, and (5) of receipt by the
Trust or the Company or any representative or attorney of the Trust or the
Company of any other communication from the Commission relating to the Trust or
the Company, the Registration Statement, any preliminary prospectus or the
Prospectus. If at any time the Commission shall issue any order suspending the
effectiveness of the Registration Statement, the Trust and the Company will make
every reasonable effort to obtain the withdrawal of such order at the earliest
possible moment. The Trust and the Company will use their best efforts to comply
with the provisions of and make all requisite filings with the Commission
pursuant to Rule 430A, if any, and to notify the Representative[s] promptly of
all such filings.

              (c)  The Trust or the Company will promptly furnish to the
Representative[s], without charge, two signed copies of the Registration
Statement and of any post-effective amendment thereto, including financial
statements and schedules, and all exhibits thereto (including any document filed
under the Exchange Act and deemed to be incorporated by reference into the
Prospectus) and will furnish to the Representative[s], without charge, for
transmittal to each of the other Underwrites, a copy of the Registration
Statement and any post-effective amendment thereto, including financial
statements and schedules.

              (d)  The Trust and the Company will comply with all the provisions
of any undertakings contained in the Registration Statement.

              (e)  On the Effective Date, and thereafter from time to time, the
Company will deliver to each of the Underwriters, without charge, as many copies
of the preliminary prospectus and Prospectus and any amendment or supplement
thereto, as the Representative[s] may reasonably request. The Company and the
Trust consent to the use of the preliminary prospectus or Prospectus and any
amendment or supplement thereto, as the case may be, by the several Underwriters
and by all dealers to whom the Offered Securities may be sold, both in
connection with the offering or sale of the Offered Securities and for any
period of time thereafter during which the Prospectus is required by law to be
delivered in connection therewith. If during such period of time any event shall
occur which in the judgment of the Company, the Trust or counsel to the
Underwriters should be set forth in the Prospectus in order to make any
statement therein, in the light of the circumstances under which they were made,
not misleading, or if it is necessary to supplement or amend the Prospectus to
comply with law, the Company will forthwith prepare and duly file with the
Commission an appropriate supplement or amendment thereto, and will deliver to
each of the Underwriters, without charge, such number of copies thereof as the
Representative[s] may


                                       14
<PAGE>   15
reasonably request. The Company shall not file any document under the Exchange
Act before the termination of the offering of the Offered Securities by the
Underwriters if such document would be deemed to be incorporated by reference
into the Prospectus which is not approved by the Representative[s] after
reasonable notice thereof.

              (f)  Prior to any public offering of the Offered Securities by the
Underwriters, the Trust and the Company will cooperate with the
Representative[s] and counsel to the Underwriters in connection with the
registration or qualification of the Offered Securities for offer and sale under
the securities or Blue Sky laws of such jurisdictions as the Representative[s]
may request; provided, that in no event shall the Trust or the Company be
obligated to qualify to do business in any jurisdiction where it is not now so
qualified or to take any action which would subject it to general service of
process in any jurisdiction where it is not now so subject.

              (g)  During the period of five years commencing on the Effective
Date, the Company will furnish to the Representative[s] and each other
Underwriter who may so request copies of such financial statements and other
periodic and special reports as the Company may from time to time distribute
generally to the holders of any class of its capital stock, and will furnish to
the Representative[s] and each Underwriter who may so request a copy of each
annual or other report it shall be required to file with the Commission.

              (h)  The Company will make generally available to holders of the
Preferred Securities and the Representative[s] as soon as may be practicable but
in no event later than the last day of the fifteenth full calendar month
following the calendar quarter in which the Effective Date falls, an earnings
statement (which need not be audited but shall be in reasonable detail) for a
period of 12 months ended commencing after the Effective Date, and satisfying
the provisions of Section 11(a) of the Act (including Rule 158 of the Rules and
Regulations).

              (i)  The Trust will apply the net proceeds from the offering and
sale of the Preferred Securities in the manner set forth in the Prospectus under
the caption "Use of Proceeds."

              (j)  During a period of [30] days from the date hereof, neither
the Trust nor the Company will, without the Representative's prior written
consent, directly or indirectly, sell, offer to sell, contract to sell, grant
any option for the sale of, or otherwise dispose of, any Preferred Securities,
any security convertible into or exchangeable into or exercisable for, Preferred
Securities or Debentures or any debt securities substantially similar to the
Debentures or any equity securities substantially similar to the Preferred
Securities, except for the Debentures and Preferred Securities offered hereby.

              (k)  The Trust and the Company will use every reasonable effort to
effect and maintain the listing of the Preferred Securities on the NYSE and to
file with the


                                       15
<PAGE>   16
NYSE all documents and notices required by the NYSE of issuers that have
securities quoted on such exchange.

              (l)  Whether or not the transactions contemplated by this
Agreement are consummated or this Agreement is terminated, the Company will pay
or cause to be paid or will reimburse if paid by the Representative[s] all costs
and expenses incident to the performance of the obligations of the Trust and the
Company under this Agreement, including but not limited to costs and expenses of
or relating to (1) the preparation, printing and filing of the Registration
Statement and exhibits to it, each preliminary prospectus, the Prospectus, any
amendment or supplement to the Registration Statement or the Prospectus and the
Indenture, (2) the preparation and delivery of certificates representing the
Preferred Securities, (3) the printing of this Agreement, the Agreement Among
Underwriters, any Dealer Agreements and any Underwriters' Questionnaire, (4)
furnishing (including cost of shipping, mailing and courier) such copies of the
Registration Statement, the Prospectus and any preliminary prospectus, and all
amendments and supplements thereto, as may be requested for use in connection
with the offering and sale of the Offered Securities by the Underwriters or by
dealers to whom Preferred Securities may be sold, (5) the listing of the
Preferred Securities on the NYSE, (6) any filings required to be made by the
Underwriters with the NASD, and the fees, disbursements and other charges of
counsel for the Underwriters in connection therewith, (7) the registration or
qualification of the Offered Securities for offer and sale under the securities
or Blue Sky laws of such jurisdictions designated pursuant to Section 4(f),
including the fees, disbursements and other charges of counsel to the
Underwriters in connection therewith, and the preparation and printing of
preliminary, supplemental and final Blue Sky memoranda, (8) counsel to the
Company, (9) the transfer agent and registrar for the Trust Securities, (10) the
rating of the Debentures by one or more rating agencies, (11) the Debt Trustee
under the Indenture, the Guarantee Trustee under the Guarantee, the Property
Trustee, the Delaware Trustee and the Regular Trustees under the Declaration and
any agents of such trustees and the fees, disbursements and other charges of
counsel for such trustees in connection with the Indenture, the Guarantee, the
Declaration and the Debentures, and (12) the Accountants.

              (m)  If this Agreement shall be terminated by the Company or the
Trust pursuant to any of the provisions hereof (other than pursuant to Section
8) or if for any reason the Company or the Trust shall be unable to perform its
obligations hereunder, the Company or the Trust will reimburse the several
Underwriters for all out-of-pocket expenses (including the fees, disbursements
and other charges of counsel to the Underwriters) reasonably incurred by them in
connection herewith.

              (n)  The Company and the Trust will not at any time, directly or
indirectly, take any action intended, or which might reasonably be expected, to
cause or result in, or which will constitute, stabilization of the price of the
Preferred Securities to facilitate the sale or resale of any of the Preferred
Securities.


                                       16
<PAGE>   17
              (o)  The Company will not claim the benefit of any usury law
against any holders of Debentures or Preferred Securities.

         5.   Conditions of Obligations of the Underwriters. The obligations of
each Underwriter hereunder are subject to the following conditions:

              (a)  Notification that the Registration Statement has become

foreign, in which litigation or proceeding an unfavorable ruling, decision or

Company and its Subsidiaries taken as a whole.

              (e)  Each of the representations and warranties of the Company and

              (n)  The Offered Securities shall be qualified for sale in such

Option Closing Date, if applicable, of the representations and warranties of the
Trust and the Company herein, as to the performance by the Trust and the Company
of their respective obligations hereunder, or as to the fulfillment of the
conditions concurrent and precedent to the obligations hereunder of the
Representative[s].

              (q)  If any of the conditions specified in this Section 5 shall
not have been fulfilled when and as required by this Agreement, or if any of the
certificates, opinions, written statements or letters furnished to the
Representative[s] or to Underwriters' Counsel pursuant to this Section 5 shall
not be in all material respects reasonably satisfactory in form and scope to the
Representative[s] and to counsel for the Underwriters, all of the Underwriters'
obligations hereunder may be canceled by the Representative[s] on, or at any
time prior to, the Closing Date. Notice of such cancellation shall be given to
the Trust and the Company in writing, or by telephone, telex or telecopy,
confirmed in writing.

Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, from and against any and all losses, claims, liabilities, expenses
and damages (including any and all investigative, legal and other expenses
reasonably incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding between any of the indemnified parties and any
indemnifying parties or between any indemnified party and any third party, or
otherwise, or any claim asserted), to which any Underwriter, or any such person,
may become subject under the Act, the Exchange Act or other Federal or state

claims, liabilities, expenses or damages arise out of or are based on any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus, the Registration Statement or the Prospectus or any
amendment or supplement to the Registration Statement or the Prospectus or the


                                       20
<PAGE>   21
omission or alleged omission to state in such document a material fact required
to be stated in it or necessary to make the statements in it not misleading,
provided that neither the Company nor the Trust will be liable to the extent
that such loss, claim, liability, expense or damage arises from the sale of the
Offered Securities in the public offering to any person by an Underwriter and is
based on an untrue statement or omission or alleged untrue statement or omission
made in reliance on and in conformity with information relating to any
Underwriter furnished in writing to the Company or the Trust by the
Representative[s] on behalf of any Underwriter expressly for inclusion in the
Registration Statement, any preliminary prospectus or the Prospectus. This
indemnity agreement will be in addition to any liability which the Trust and the
Company might otherwise have including under this Agreement.

              (b)  Each Underwriter will indemnify and hold harmless (i) the
Trust, the Trustees, its officers who sign the Registration Statement and any
person controlling the Trust with the meaning of Section 15 of the Act or
Section 20 of the Exchange Act and (ii) the Company, its directors, its officers
who shall have signed the Registration Statement, and each other person, if any,
who controls the Company within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, in each case to the same extent as the foregoing
indemnity from the Trust and the Company to each Underwriter, but only insofar
as losses, liabilities, claims, expenses or damages arise out of or are based
upon any untrue statement or omission or alleged untrue statement or omission,
made in reliance on and in conformity with written information furnished to the
Trust or the Company by the Representative[s] expressly for use in the
Registration Statement, any preliminary prospectus or the Prospectus. This
indemnity will be in addition to any liability that each Underwriter may
otherwise have, including under this Agreement; provided, however,that in no
case shall any Underwriter be liable or responsible for any amount in excess of
the compensation payable to such Underwriter pursuant to Section 1(c) hereof.

              (c)  Any party that proposes to assert the right to be indemnified
under this Section 6 will, promptly after receipt of notice of commencement of
any action against such party in respect of which a claim is to be made against
an indemnifying party or parties under this Section 6, notify each such
indemnifying party of the commencement of such action, enclosing a copy of all
papers served, but the omission so to notify such indemnifying party will not
relieve it from any liability that it may have to any indemnified party under
the foregoing provisions of this Section 6 unless, and only to the extent that,
such omission results in the forfeiture of substantive rights or defenses by the
indemnifying party. If any such action is brought against any indemnified party
and it notifies the indemnifying party of its commencement, the indemnifying
party will be entitled to participate in and, to the extent that it elects by
delivering written notice to the indemnified party promptly after receiving
notice of the commencement of the action from the indemnified party, jointly
with any other indemnifying party similarly notified, to assume the defense of
the action, with counsel satisfactory to the indemnified party, and after notice
from the indemnifying party to the indemnified party of its election to assume
the defense, the indemnifying party will not be liable to the indemnified party
for any legal or other


                                       21
<PAGE>   22
expenses except as provided below and except for the reasonable costs of
investigation subsequently incurred by the indemnified party in connection with
the defense. The indemnified party will have the right to employ its own counsel
in any such action, but the fees, expenses and other charges of such counsel
will be at the expense of such indemnified party unless (1) the employment of
counsel by the indemnified party has been authorized in writing by the
indemnifying party, (2) the indemnified party has reasonably concluded (based on
advice of counsel) that there may be legal defenses available to it or other
indemnified parties that are different from or in addition to those available to
the indemnifying party, (3) a conflict or potential conflict exists (based on
advice of counsel to the indemnified party) between the indemnified party and
the indemnifying party (in which case the indemnifying party will not have the
right to direct the defense of such action on behalf of the indemnified party),
or (4) the indemnifying party has not in fact employed counsel to assume the
defense of such action within a reasonable time after receiving notice of the
commencement of the action, in each of which cases the reasonable fees,
disbursements and other charges of counsel will be at the expense of the
indemnifying party or parties. It is understood that the indemnifying party or
parties shall not, in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees, disbursements and
other charges of more than one separate firm admitted to practice in such
jurisdiction at any one time for all such indemnified party or parties. All such
fees, disbursements and other charges will be reimbursed by the indemnifying
party promptly as they are incurred. An indemnifying party will not be liable
for any settlement of any action or claim effected without its written consent
(which consent will not be unreasonably withheld). No indemnifying party shall,
without the prior written consent of each indemnified party, settle or
compromise or consent to the entry of any judgment in any pending or threatened
claim, action or proceeding relating to the matters contemplated by this Section
6 (whether or not any indemnified party is a party thereto), unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising or that may arise out of such
claim, action or proceeding.

              (d)  In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing
paragraphs of this Section 6 is applicable in accordance with its terms but for
any reason is held to be unavailable from the Trust and the Company or the
Underwriters, the Trust, the Company and the Underwriters shall contribute to
the aggregate losses, claims, liabilities, expenses and damages (including any
investigative, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any action, suit or proceeding or any
claims asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Trust or the Company, any contribution
received by the Trust or the Company from persons other than the Underwriters,
such as persons who control the Trust or the Company within the meaning of the
Act and directors and officers of the Company) to which the Trust, the Company
and any one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Trust and the
Company on the one hand and the Underwriters on the other. The relative benefits
received by the Trust and the Company on the one hand and the Underwriters on
the other shall be


                                       22
<PAGE>   23
deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Trust bear to the total compensation
received by the Underwriters pursuant to Section 1(c) hereof, respectively, in
each case as set forth in the table on the cover page of the Prospectus. If, but
only if, the allocation provided by the foregoing sentence is not permitted by
applicable law, the allocation of contribution shall be made in such proportion
as is appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the Trust and the Company on
the one hand and the Underwriters on the other with respect to the statements or
omissions which resulted in such loss, claim, liability, expense or damage, or
action in respect thereof, as well as any other relevant equitable
considerations with respect to such offering. The relative fault of the Trust
and the Company on the one hand and of the Underwriters on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact related to information supplied by the Trust or the Company or
the Underwriters, the intent of the parties and their relative knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Trust, the Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 6(d) were to be determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take into
account the equitable considerations referred herein. The amount paid or payable
by an indemnified party as a result of the loss, claim, liability, expense or
damage, or action in respect thereof, referred to above in this Section 6(d)
shall be deemed to include, for purpose of this Section 6(d), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no Underwriter shall be required to contribute
any amount in excess of the compensation received by it pursuant to Section 1(c)
hereof, and no person found guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) will be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute as provided in this Section 6(d) are
several in proportion to their respective underwriting obligations and not
joint. For purposes of this Section 6(d), any person who controls a party to
this Agreement within the meaning of the Act will have the same rights to
contribution as that party, and each officer of the Trust and the Company who
signed the Registration Statement will have the same rights to contribution as
the Trust and the Company, respectively, subject in each case to the provisions
hereof. Any party entitled to contribution, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim for
contribution may be made under this Section 6(d), will notify any such party or
parties from whom contribution may be sought, but the omission so to notify will
not relieve the party or parties from whom contribution may be sought from any
other obligation it or they may have under this Section 6(d). No party will be
liable for contribution with respect to any action or claim settled without its
written consent (which consent will not be unreasonably withheld).

              (e)  The indemnity and contribution agreements contained in this
Section 6 and the representations and warranties of the Company contained in
this Agreement


                                       23
<PAGE>   24
shall remain operative and in full force and effect regardless of (i) any
investigation made by or on behalf of the Underwriters, (ii) acceptance of any
of the Offered Securities and payment therefor, or (iii) any termination of this
Agreement.

         7.   Termination. The obligations of the several Underwriters under
this Agreement may be terminated at any time on or prior to the Closing Date
(or, with respect to the Option Securities, on or prior to the Option Closing
Date), by notice to the Trust and the Company from the Representative[s],
without liability on the part of any Underwriter to the Trust or the Company,
if, prior to delivery and payment for the Preferred Securities (or the Option
Securities, as the case may be), in the sole judgment of the Representative[s],
(i) trading in any of the equity securities of the Company shall have been
suspended by the Commission, by an exchange that lists the Preferred Securities
or by the Nasdaq Stock Market, (ii) trading in securities generally on the NYSE
shall have been suspended or limited or minimum or maximum prices shall have
been generally established on such exchange, or additional material governmental
restrictions, not in force on the date of this Agreement, shall have been
imposed upon trading in securities generally by such exchange or by order of the
Commission or any court or other governmental authority, (iii) a general banking
moratorium shall have been declared by either Federal or New York State
authorities, or (iv) any material adverse change in the financial or securities
markets in the United States or in political, financial or economic conditions
in the United States or any outbreak or material escalation of hostilities or
declaration by the United States of a national emergency or war or other
calamity or crisis shall have occurred, the effect of any of which is such as to
make it, in the sole judgment of the Representative[s], impracticable or
inadvisable to market the Offered Securities on the terms and in the manner
contemplated by the Prospectus.

         8.   Substitution of Underwriters. If any one or more of the
Underwriters shall fail or refuse to purchase any of the Firm Securities which
it or they have agreed to purchase hereunder, and the aggregate principal amount
of Firm Securities which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate
principal amount of Firm Securities, the other Underwriters shall be obligated,
severally, to purchase the Firm Securities which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase, in the proportions which
the principal amount of Firm Securities which they have respectively agreed to
purchase pursuant to Section 1 bears to the aggregate principal amount of Firm
Securities which all such non-defaulting Underwriters have so agreed to
purchase, or in such other proportions as the Representative[s] may specify;
provided that in no event shall the maximum principal amount of Firm Securities
which any Underwriter has become obligated to purchase pursuant to Section 1 be
increased pursuant to this Section 8 by more than one-ninth of the principal
amount of Firm Securities agreed to be purchased by such Underwriter without the
prior written consent of such Underwriter. If any Underwriter or Underwriters
shall fail or refuse to purchase any Firm Securities and the aggregate principal
amount of Firm Securities which such defaulting Underwriter or Underwriters
agreed but failed or refused to purchase exceeds one-tenth of the aggregate
principal amount of the Firm Securities and arrangements satisfactory to the
Representative[s] and the Trust and the


                                       24
<PAGE>   25
Company for the purchase of such Firm Securities are not made within 48 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Underwriter or the Trust and the Company for the purchase
or sale of any Preferred Securities under this Agreement. In any such case
either the Representative[s] or the Trust and the Company shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and in
the Prospectus or in any other documents or arrangements may be effected. Any
action taken pursuant to this Section 8 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         9.   Miscellaneous. Notice given pursuant to any of the provisions of
this Agreement shall be in writing and, unless otherwise specified, shall be
mailed or delivered (a) if to the Trust, at 1285 Avenue of the Americas, New
York, New York, 10019 Attention: Treasurer, Paine Webber Group, Inc., or (b) if
to the Company, at the office of the Company, 1285 Avenue of the Americas, New
York, New York, Attention: Treasurer, Paine Webber Group, Inc., or (c) if to the
Underwriters, to the Representative[s] at the offices of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019, Attention:
Corporate Finance Department. Any such notice shall be effective only upon
receipt. Any notice under Section 8 or 9 may be made by telex or telephone, but
if so made shall be subsequently confirmed in writing.

         This Agreement has been and is made solely for the benefit of the
several Underwriters and the Trust and the Company and of the controlling
persons, directors and officers referred to in Section 6, and their respective
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. The term "successors and assigns" as used
in this Agreement shall not include a purchaser, as such purchaser, of Offered
Securities from any of the several Underwriters.

         All representations, warranties and agreements of the Trust and the
Company contained herein or in certificates or other instruments delivered
pursuant hereto, shall remain operative and in full force and effect regardless
of any investigation made by or on behalf of any Underwriter or any of their
controlling persons and shall survive delivery of and payment for the Preferred
Securities hereunder.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE.

         This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

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

provision hereof waived except by an instrument in writing signed by the
Representative[s], the Trust and the Company.

                                         _________ __, 1996


To Each of the Persons Listed
on Schedule I Hereto

              Re:  PWG Capital Trust [  ]

Ladies and Gentlemen:

              We have acted as special Delaware counsel for PWG Capital Trust 
[ ], a Delaware business trust (the "Trust"), in connection with the matters set
forth herein. At your request, this opinion is being furnished to you.

              For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

              (a)      The Certificate of Trust of the Trust, dated as of
                       _________ __, 1996 (the "Certificate"), as filed in
                       the office of the Secretary of State of the State of
                       Delaware (the "Secretary of State") on __________ __,
                       1996;

              (b)      The Declaration of Trust of the Trust, dated as of
                       _________ __, 1996, among Paine Webber Group Inc., a
                       Delaware corporation ("Paine Webber"), and the
                       trustees of the Trust named therein;

              (c)      The Amended and Restated Declaration of Trust of the
                       Trust, dated as of _______ __, 1996 (including
                       Exhibits __, __ and __ thereto) (the "Declaration"),
                       among Paine Webber, the trustees of the Trust named
                       therein (collectively, the "Trustees") and the
                       holders, from time to time, of undivided beneficial
                       interests in the assets of the Trust;

              (d)      The Underwriting Agreement, dated ____________, 1996
                       (the "Underwriting Agreement"), among the Trust,
                       Paine Webber and PaineWebber Incorporated,
                       individually and as Representative[s] of the several
                       underwriters named in Schedule I thereto (the
                       "Underwriters");


                                       C-1
<PAGE>   32
              (e)      The Prospectus, dated ____________, 1996 (the
                       "Prospectus"), relating to the issuance of ___ shares
                       of the __% Preferred Trust Securities of the Trust
                       representing preferred undivided beneficial interests
                       in the assets of Trust (each, a "Preferred Security"
                       and collectively, the "Preferred Securities"); and

              (f)      A Certificate of Good Standing for the Trust, dated the
                       date hereof, obtained from the Secretary of State.

         Initially capitalized terms used herein and not otherwise defined are
used as defined in the Declaration.

         For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (f) above. In particular, we
have not reviewed any document (other than the documents listed in paragraphs
(a) through (f) above) that is referred to in or incorporated by reference into
the documents reviewed by us. We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein. We have conducted no independent factual investigation of our own
but rather have relied solely upon the foregoing documents, the statements and
information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

         With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

         For purposes of this opinion, we have assumed (i) that the Declaration
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation,and
termination of the Trust, and that the Declaration and the Certificate are in
full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due creation, due formation or due
organization, as the case may be, and valid existence in good standing of each
party to the documents examined by us under the laws of the jurisdiction
governing its creation, formation or organization, (iii) the legal capacity of
each natural person who is a party to the documents examined by us, (iv) except
to the extent provided in paragraph 4 below, that each of the parties to the
documents examined by us has the power and authority to execute and deliver, and
to perform its obligations under, such documents, (v) except to the extent
provided in paragraph 5 below, that each of the parties to the documents
examined by us has duly authorized, executed and delivered such documents, (vi)
the receipt by each Person to whom a Preferred Security is to be issued by the
Trust (the "Holders") of a Preferred Securities Certificate for such Preferred
Security and the payment for the Preferred Security acquired by it, in
accordance with the Declaration and the Prospectus, (vii) that the


                                       C-2
<PAGE>   33
Preferred Securities are issued and sold to the Holders in accordance with the
Declaration and the Prospectus, (viii) that the Trust derives no income from or
connected with sources within the State of Delaware and has no assets,
activities (other than having a Delaware trustee as required by the Delaware
Business Trust Act and the filing of documents with the Secretary of State) or
employees in the State of Delaware, and (ix) that the Trust is treated as a
grantor trust for federal income tax purposes. We have not participated in the
preparation of the Prospectus and assume no responsibility for its contents.

         This opinion is limited to the laws of the State of Delaware (excluding
the securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations relating thereto. Our opinions are rendered only with
respect to Delaware laws and rules, regulations and orders thereunder that are
currently in effect.

         Based upon the foregoing, and upon our examination of such questions of
law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

         1. The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, and all
filings required under the laws of the State of Delaware with respect to the
creation and valid existence of the Trust as a business trust have been made.

         2. Under the Delaware Business Trust Act and the Declaration, the Trust
has the trust power and authority to own its property and conduct its business,
all as described in the Prospectus.

         3. The Declaration constitutes a valid and binding obligation of Paine
Webber and the Trustees, and is enforceable against Paine Webber and the
Trustees, in accordance with its terms.

         4. Under the Delaware Business Trust Act and the Declaration, the Trust
has the trust power and authority (i) to execute and deliver, and to perform its
obligations under, the Underwriting Agreement, and (ii) to issue and perform its
obligations under the Preferred Securities.

         5. Under the Delaware Business Trust Act and the Declaration, the
execution and delivery by the Trust of the Underwriting Agreement and the
performance by the Trust of its obligations thereunder, have been duly
authorized by all necessary trust action on the part of the Trust.

         6. The Preferred Securities have been duly authorized by the
Declaration and are duly and validly issued and, subject to the qualifications
set forth herein, fully paid


                                       C-3
<PAGE>   34
and nonassessable undivided beneficial interests in the assets of the Trust and
are entitled to the benefits of the Declaration. The Holders, as beneficial
owners of the Trust, will be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware. We note that the
Holders may be obligated, pursuant to the Declaration, (i) to provide indemnity
and/or security in connection with and pay taxes or governmental charges arising
from transfers or exchanges of Preferred Securities Certificates and the
issuance of replacement Preferred Securities Certificates, and (ii) to provide
security or indemnity in connection with requests of or directions to the
Property Trustee to exercise its rights and powers under the Declaration.

         7.  The Common Securities have been duly authorized by the Declaration
and, when issued and sold in accordance with the Declaration, represent validly
issued beneficial interests in the assets of the Trust.

         8.  Under the Delaware Business Trust Act, the certificate attached to
the Declaration as Exhibit is an appropriate form of certificate to evidence
ownership of the Preferred Securities.

         9.  Under the Delaware Business Trust Act and the Declaration, the
issuance of the Preferred Securities is not subject to preemptive rights.

         10. The issuance and sale by the Trust of the Preferred Securities, the
execution, delivery and performance by the Trust of the Underwriting Agreement,
the consummation by the Trust of the transactions contemplated thereby and
compliance by the Trust with its obligations thereunder do not violate (i) any
of the provisions of the Certificate or the Declaration, or (ii) any applicable
Delaware law or administrative regulation.

         11. No authorization, approval, consent or order of any Delaware court
or Delaware governmental authority or agency is required to be obtained by the
Trust solely in connection with the issuance and sale of the Preferred
Securities.

         12. The Holders of the Preferred Securities (other than those Holders
who reside or are domiciled in the State of Delaware) will have no liability for
income taxes imposed by the State of Delaware solely as a result of their
participation in the Trust, and the Trust will not be liable for any income tax
imposed by the State of Delaware.

         The opinion expressed in paragraph 3 above is subject, as to
enforcement, to the effect upon the Declaration of (i) bankruptcy, insolvency,
moratorium, receivership, reorganization, liquidation, fraudulent transfer and
other similar laws relating to or affecting the rights and remedies of creditors
generally, (ii) principles of equity, including applicable law relating to
fiduciary duties (regardless of whether considered and applied in a proceeding
in equity or at law), and (iii) the effect of applicable public policy on the
enforceability of provisions relating to indemnification or contribution.

                (11) whether the Debentures of the series are issuable as a
         Global Debenture and, in such case, the identity of the Depositary for
         the Debentures of the series.

                (12) any and all other terms with respect to the Debentures of
         the series (which terms shall not be inconsistent with the terms of
         this Indenture);

                (13) if the Debentures of the series are to be deposited as
         trust assets in a PWG Capital Trust, the name of the applicable PWG
         Capital Trust (which shall distinguish such statutory business trust
         from all other PWG Capital Trusts) into which the Debentures of the
         series are to be deposited as trust assets and the date of its
         Declaration of Trust; and

                  (14) any condition to, or restriction on, the transferability
         of the Debentures.

                  All Debentures of any one series shall be substantially
identical except as to denomination and except as may otherwise be provided in
or pursuant to any indenture supplemental hereto.

                  SECTION 2.02. The Debentures of any series and the Trustee's
certificate of authentication to be borne by such Debentures shall be
substantially of the tenor and purport as set forth in one or more indentures
supplemental hereto and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock

                                                                              11


exchange on which Debentures of that series may be listed, or to conform to
usage.

                  SECTION 2.03. The Debentures shall be issuable as registered
Debentures and in the denominations of $25 or any integral multiple thereof,
subject to Section 2.01(10). The Debentures of a particular series shall bear
interest payable on the dates and at the rate specified with respect to that
series. The principal of and the interest on the Debentures of any series, as
well as any premium thereon in case of redemption thereof prior to maturity,
shall be payable in such coin or currency of the United States of America as at
the time of payment is legal tender for public and private debt, at the office
or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City and State of New York. Each Debenture shall be dated the
date of its authentication. Interest on the Debentures shall be computed on the
basis of a 360-day year of twelve 30-day months.

                  The interest installment on any Debenture which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date for
Debentures of that series shall be paid to the person in whose name such
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on the regular record date for such interest installment. In the event
that any Debenture of a particular series or portion thereof is called for
redemption and the redemption date is subsequent to a regular record date with
respect to any Interest Payment Date for Debentures of that series and on or
prior to such Interest Payment Date, interest on such Debenture will be paid
upon presentation and surrender of such Debenture as provided in Section 3.03.

                  Any interest on any Debenture which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date for
Debentures of that series (herein called "Defaulted Interest") shall forthwith
cease to be payable to the registered holder on the relevant regular record date
by virtue of having been such holder; and such Defaulted Interest shall be paid
by the Company, at its election, as provided in clause (1) or clause (2) below:

                  (1) The Company may make payment of any Defaulted Interest on
         Debentures to the persons in whose names such Debentures (or their
         respective Predecessor Debentures) are registered at the close of
         business on
<PAGE>   25
                                                                              12


         a special record date for the payment of such Defaulted Interest, which
         shall be fixed in the following manner: the Company shall notify the
         Trustee in writing of the amount of Defaulted Interest proposed to be
         paid on each such Debenture and the date of the proposed payment, and
         at the same time the Company shall deposit with the Trustee an amount
         of money equal to the aggregate amount proposed to be paid in respect
         of such Defaulted Interest or shall make arrangements satisfactory to
         the Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a special record date for the payment
         of such Defaulted Interest which shall not be more than 20 nor less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         special record date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the special record date therefor to be mailed, first-class postage
         prepaid, to each Debentureholder at his or her address as it appears in
         the Debenture Register (as hereinafter defined), not less than 10 days
         prior to such special record date. Notice of the proposed payment of
         such Defaulted Interest and the special record date therefor having
         been mailed as aforesaid, such Defaulted Interest shall be paid to the
         persons in whose names such Debentures (or their Predecessor
         Debentures) are registered on such special record date and shall be no
         longer payable pursuant to the following clause (2).

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

                  Unless otherwise set forth in one or more indentures
supplemental hereto establishing the terms of any series of Debentures pursuant
to Section 2.01, the term
<PAGE>   26
                                                                              13


"regular record date" as used in this Section with respect to a series of
Debentures with respect to any Interest Payment Date for such series shall mean
either (x) the fifteenth day of the month immediately preceding the month in
which an Interest Payment Date established for such series pursuant to Section
2.01 shall occur, if such Interest Payment Date is the first day of a month, or
(y) the first day of the month in which an Interest Payment Date established for
such series pursuant to Section 2.01 shall occur, if such Interest Payment Date
is the fifteenth day of a month, whether or not such date is a Business Day.

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

                  SECTION 2.04. Subject to the provisions of Section 2.06, the
Debentures shall be printed, lithographed or engraved on steel engraved borders
or produced by any combination of these methods or may be produced in any other
manner, as the proper officers of the Company may determine, and shall be signed
on behalf of the Company by the Chairman or Vice Chairman of its Board of
Directors or its Chief Executive Officer, President or one of its Vice
Presidents, or its Treasurer or any Assistant Treasurer under its corporate seal
attested by its Secretary or one of its Assistant Secretaries. The signature of
the Chairman, Vice Chairman, Chief Executive Officer, President, any Vice
President, the Treasurer or any Assistant Treasurer and/or the signature of the
Secretary or any Assistant Secretary in attestation of the corporate seal, upon
the Debentures, may be in the form of a manual or facsimile signature of a
present or any future Chairman, Vice Chairman, President, Vice President,
Treasurer or Assistant Treasurer and of a present or any future Secretary or
Assistant Secretary and may be imprinted or otherwise reproduced on the
Debentures and for that purpose the Company may use the manual or facsimile
signature of any person who shall have been a Chairman, Vice Chairman, Chief
Executive Officer, President, Vice President, Treasurer or Assistant Treasurer
or any person who shall have been a Secretary or Assistant Secretary,
notwithstanding the fact that at the time the Debentures shall be authenticated
and delivered, or disposed of, such person shall have ceased to be the Chairman,
Vice
<PAGE>   27
                                                                              14


Chairman, Chief Executive Officer, President or a Vice President, or the
Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary,
of the Company, as the case may be. The seal of the Company may be in the form
of a facsimile of the seal of the Company and may be impressed, affixed,
imprinted or otherwise reproduced on the Debentures.

                  Only such Debentures as shall bear thereon a Certificate of
Authentication substantially in the form established for such Debentures,
executed manually by an authorized signatory of the Trustee, or by any
Authenticating Agent with respect to such Debentures, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such
Certificate of Authentication executed by the Trustee, or by any Authenticating
Agent appointed by the Trustee with respect to such Debentures, upon any
Debenture executed by the Company shall be conclusive evidence that the
Debenture so authenticated has been duly authenticated and made available for
delivery hereunder and that the holder is entitled to the benefits of this
Indenture.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Debentures of any series
executed by the Company to the Trustee for authentication, together with a
written order of the Company in the form of an Officers' Certificate for the
authentication and delivery of such Debentures, and the other documents required
by Section 13.06, and the Trustee, in accordance with such written order, shall
authenticate and make available for delivery such Debentures.

                  The Trustee shall not be required to authenticate such
Debentures if the issue of such Debentures pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Debentures, this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee.

                           SECTION 2.05.  (a)  Debentures of any series
may be exchanged, upon presentation thereof at the office or agency of the
Company designated for such purpose in the Borough of Manhattan, the City and
State of New York, for other Debentures of such series of authorized
denominations, and for a like aggregate principal amount, upon payment of a sum
sufficient to cover any tax or other governmental charge
<PAGE>   28
                                                                              15


in relation thereto, all as provided in this Section. In respect of any
Debentures so surrendered for exchange, the Company shall execute, the Trustee
shall authenticate and such office or agency shall make available for delivery
in exchange therefor the Debenture or Debentures of the same series which the
Debentureholder making the exchange shall be entitled to receive, bearing
numbers not contemporaneously outstanding.

                  (b) The Company shall keep, or cause to be kept, at its office
or agency designated for such purpose in the Borough of Manhattan, the City and
State of New York, or such other location designated by the Company a register
or registers (herein referred to as the "Debenture Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall register
the Debentures and the transfers of Debentures as in this Article provided and
which at all reasonable times shall be open for inspection by the Trustee. The
registrar for the purpose of registering Debentures and transfers of Debentures
as herein provided shall be appointed as authorized by Board Resolution (the
"Debenture Registrar").

                  Upon surrender for registration of transfer of any Debenture
at the office or agency of the Company designated for such purpose in the
Borough of Manhattan, the City and State of New York, the Company shall execute,
the Trustee shall authenticate and such office or agency shall make available
for delivery in the name of the transferee or transferees a new Debenture or
Debentures of the same series as the Debenture presented for a like aggregate
principal amount.

                  All Debentures presented or surrendered for exchange or
registration of transfer, as provided in this Section, shall be accompanied (if
so required by the Company or the Debenture Registrar) by a written instrument
or instruments of transfer, in form satisfactory to the Company or the Debenture
Registrar, duly executed by the registered holder or by his duly authorized
attorney in writing.

                  (c) No service charge shall be made for any exchange or
registration of transfer of Debentures, or issue of new Debentures in case of
partial redemption of any series, but the Company may require payment by the
Debentureholder requesting an exchange or registration of transfer of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than in
<PAGE>   29
                                                                              16


connection with exchanges made pursuant to Section 2.06, Section 3.03(b) and
Section 9.04 not involving any transfer.

                  (d) The Company shall not be required (i) to issue, register
the transfer of or exchange any Debentures of a series during a period beginning
at the opening of business 15 days before the day of the mailing of a notice of
redemption of all or less than all of the outstanding Debentures of such series
and ending at the close of business on the day of such mailing or (ii) register
the transfer of or exchange any Debentures so selected for redemption, in whole
or in part, except the unredeemed portion of any Debentures being redeemed in
part. The provisions of this Section 2.05 are, with respect to any Global
Debenture, subject to Section 2.11.

                  SECTION 2.06. Pending the preparation of definitive Debentures
of any series, the Company may execute, and the Trustee shall authenticate and
make available for delivery, temporary Debentures (printed, lithographed or
typewritten) of any authorized denomination, and substantially in the form of
the definitive Debentures in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Debentures, all as may be determined by the Company. Every temporary Debenture
of any series shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Debentures of such series. Without unnecessary
delay the Company will execute and will furnish definitive Debentures of such
series and thereupon any or all temporary Debentures of such series may be
surrendered in exchange therefor (without charge to the holders), at the office
or agency of the Company designated for the purpose in the Borough of Manhattan,
the City and State of New York, and the Trustee shall authenticate and such
office or agency shall make available for delivery in exchange for such
temporary Debentures an equal aggregate principal amount of definitive
Debentures of such series, unless the Company advises the Trustee to the effect
that definitive Debentures need not be executed and furnished until further
notice from the Company. Until so exchanged, the temporary Debentures of such
series shall be entitled to the same benefits under this Indenture as definitive
Debentures of such series authenticated and delivered hereunder.
<PAGE>   30
                                                                              17


                  SECTION 2.07. In case any temporary or definitive Debenture
shall become mutilated or be destroyed, lost or stolen, the Company (subject to
the next succeeding sentence) shall execute, and upon its request the Trustee
(subject as aforesaid) shall authenticate and make available for delivery, a new
Debenture of the same series bearing a number not contemporaneously Outstanding,
in exchange and substitution for the mutilated Debenture, or in lieu of and in
substitution for the Debenture so destroyed, lost or stolen. In every case the
applicant for a substituted Debenture shall furnish to the Company and to the
Trustee such security or indemnity as may be required by them to save each of
them harmless, and, in every case of destruction, loss or theft, the applicant
shall also furnish to the Company and to the Trustee evidence to their
satisfaction of the destruction, loss or theft of the applicant's Debenture and
of the ownership thereof. The Trustee may authenticate any such substituted
Debenture and make available for delivery the same upon the written request or
authorization of any officer of the Company. Upon the issuance of any
substituted Debenture, the Company may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee)
connected therewith. In case any Debenture which has matured or is about to
mature shall become mutilated or be destroyed, lost or stolen, the Company may,
instead of issuing a substitute Debenture, pay or authorize the payment of the
same (without surrender thereof except in the case of a mutilated Debenture) if
the applicant for such payment shall furnish to the Company and to the Trustee
such security or indemnity as they may require to save each of them harmless,
and, in case of destruction, loss or theft, evidence to the satisfaction of the
Company and the Trustee of the destruction, loss or theft of such Debenture and
of the ownership thereof.

                  Every Debenture issued pursuant to the provisions of this
Section in substitution for any Debenture which is mutilated, destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Debenture shall be found at any
time, or be enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Debentures of
the same series duly issued hereunder. All Debentures shall be held and owned
upon the express condition that the foregoing provisions are exclusive with
respect to the replacement or
<PAGE>   31
                                                                              18


payment of mutilated, destroyed, lost or stolen Debentures, and shall preclude
(to the extent lawful) any and all other rights or remedies, notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

                  SECTION 2.08. All Debentures surrendered for the purpose of
payment, redemption, exchange or registration of transfer shall, if surrendered
to the Company or any paying agent, be delivered to the Trustee for
cancellation, or, if surrendered to the Trustee, shall be canceled by it, and no
Debentures shall be issued in lieu thereof except as expressly required or
permitted by any of the provisions of this Indenture. On written request of the
Company, the Trustee shall deliver to the Company canceled Debentures held by
the Trustee. If the Company shall otherwise acquire any of the Debentures,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Debentures unless and until the same are
delivered to the Trustee for cancelation.

                  SECTION 2.09. Nothing in this Indenture or in the Debentures,
express or implied, shall give or be construed to give to any Person, other than
the parties hereto and the holders of the Debentures, any legal or equitable
right, remedy or claim under, or in respect of, this Indenture, or under any
covenant, condition or provision herein contained; all such covenants,
conditions and provisions being for the sole benefit of the parties hereto and
of the holders of the Debentures.

                  SECTION 2.10. So long as any of the Debentures of any series
remain Outstanding there may be an Authenticating Agent for any or all such
series of Debentures which the Trustee shall have the right to appoint. Said
Authenticating Agent shall be authorized to act on behalf of the Trustee to
authenticate Debentures of such series issued upon exchange, transfer or partial
redemption thereof, and Debentures so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. All references in this Indenture to
the authentication of Debentures by the Trustee shall be deemed to include
authentication by an Authenticating Agent for such series except for
authentication upon original issuance or pursuant to Section 2.07 hereof. Each
Authenticating Agent shall be acceptable to the Company and shall be a
<PAGE>   32
                                                                              19


corporation which has a combined capital and surplus, as most recently reported
or determined by it, sufficient under the laws of any jurisdiction under which
it is organized or in which it is doing business to conduct a trust business,
and which is otherwise authorized under such laws to conduct such business and
is subject to supervision or examination by Federal or state authorities. If at
any time any Authenticating Agent shall cease to be eligible in accordance with
these provisions, it shall resign immediately.

                  Any Authenticating Agent may at any time resign by giving
written notice of resignation to the Trustee and to the Company. The Trustee may
at any time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

                  SECTION 2.11. (a) If, pursuant to Section 2.01, the Company
shall establish that the Debentures of a particular series are to be issued as
one or more Global Debentures, then the Company shall execute, and the Trustee
shall, in accordance with Section 2.04, authenticate and deliver, one or more
Global Debentures which (i) shall represent, and shall be denominated in an
aggregate amount equal to the aggregate principal amount of, all of the
Outstanding Debentures of such series, (ii) shall be registered in the name of
the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.11 of the Indenture, this Debenture may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary."

                  (b) Notwithstanding the provisions of Section 2.05, the Global
Debenture of a series may be transferred, in whole but not in part and in the
manner provided in Section 2.05, only to another nominee of the Depositary for
such series, or to a successor Depositary for
<PAGE>   33
                                                                              20


such series selected or approved by the Company or to a nominee of such
successor Depositary.

                  (c) If at any time the Depositary for a series of Debentures
notifies the Company that it is unwilling or unable to continue as Depositary
for such series or if at any time the Depositary for such series shall no longer
be registered, or in good standing, under the Exchange Act or other applicable
statute or regulation and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, this Section 2.11 shall
no longer be applicable to the Debentures of such series, and the Company will
execute, and subject to Section 2.05, the Trustee will authenticate and make
available for delivery, Debentures of such series in definitive registered form
without coupons, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Debenture of such series in
exchange for such Global Debenture. In addition, the Company may at any time
determine that the Debentures of any series shall no longer be represented by
one or more Global Debentures and that the provisions of this Section 2.11 shall
no longer apply to the Debentures of such series. In such event, the Company
will execute and, subject to Section 2.05, the Trustee, upon receipt of an
Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver Debentures of such series in definitive registered
form, without coupons, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global Debenture of such
series in exchange for such Global Debenture. Upon the exchange of a Global
Debenture for such Debentures in definitive registered form, without coupons, in
authorized denominations, the Global Debenture shall be canceled by the Trustee.
Any Debentures in definitive registered form issued in exchange for a Global
Debenture pursuant to this Section 2.11(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Debentures to the Depositary for
delivery to the persons in whose names such Debentures are so registered.

                  (d) None of the Company, the Trustee, any paying agent or the
security registrar will have any responsibility or liability for any aspect of
the records relating to or
<PAGE>   34
                                                                              21


payments made on account of the beneficial ownership interests of a Global
Debenture or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

                  SECTION 2.12. CUSIP Numbers. The Company in issuing the
Debentures may use "CUSIP" and "CINS" numbers (if then generally in use), and
the Trustee shall use CUSIP numbers or CINS numbers, as the case may be, in
notices of redemption or exchange as a convenience to Debentureholders but no
representation shall be made by the Company, the Trustee or any other Person as
to the correctness of such numbers either as printed on the Debentures or as
contained in any notice of redemption or exchange.


                                   ARTICLE III

                          Redemption of Debentures and
                             Sinking Fund Provisions

                  SECTION 3.01. The Company may redeem the Debentures of any
series issued hereunder on and after the dates and in accordance with the terms
established for such series pursuant to Section 2.01.

                  SECTION 3.02. (a) In case the Company shall desire to exercise
such right to redeem all or, as the case may be, a portion of the Debentures of
any series in accordance with the right reserved so to do, it shall give notice
of such redemption by mail, first class postage prepaid, not less than 30 nor
more than 60 days before the date fixed for redemption to holders of the
Debentures of the series to be redeemed at their last addresses as they shall
appear upon the Debenture Register. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the registered holder receives the notice. In any case, failure duly to
give such notice to the holder of any Debenture of any series designated for
redemption in whole or in part, or any defect in the notice, shall not affect
the validity of the proceedings for the redemption of any other Debentures of
such series or any other series. In the case of any redemption of Debentures
prior to the expiration of any restriction on such redemption provided in the
terms of such Debentures or elsewhere in this Indenture, the Company shall
furnish the Trustee with an Officers' Certificate evidencing compliance with any
such restriction.
<PAGE>   35
                                                                              22


                  Each such notice of redemption (which shall be irrevocable)
shall specify the date fixed for redemption and the redemption price at which
Debentures of that series are to be redeemed, and shall state that payment of
the redemption price of such Debentures to be redeemed will be made at the
office or agency of the Company in the Borough of Manhattan, the City and State
of New York, upon presentation and surrender of such Debentures, that interest
accrued to the date fixed for redemption will be paid as specified in said
notice, that from and after said date interest will cease to accrue and that the
redemption is for a sinking fund, if such is the case. If less than all the
Debentures of a series are to be redeemed, the notice to the holders of
Debentures of that series to be redeemed in whole or in part shall specify the
particular Debentures to be so redeemed. In case any Debenture is to be redeemed
in part only, the notice which relates to such Debenture shall state the portion
of the principal amount thereof to be redeemed and shall state that, on and
after the redemption date, upon surrender of such Debenture, a new Debenture or
Debentures of such series in principal amount equal to the unredeemed portion
thereof will be issued. If the Company gives a notice of redemption in respect
of Debentures of a series, then, by 12:00 noon, New York City time, on the date
fixed for redemption, the Company will deposit irrevocably with the Trustee
funds sufficient to pay the applicable redemption price and will give
irrevocable instructions and authority to pay such redemption price to the
holders of Debentures of such series.

                  (b) If less than all the Debentures of a series are to be
redeemed, the Company shall give the Trustee at least 45 days notice in advance
of the date fixed for redemption (unless a shorter notice shall be satisfactory
to the Trustee) as to the aggregate principal amount of Debentures of the series
to be redeemed, an thereupon the Trustee shall select, by lot or in any other
manner as it shall deem appropriate and fair in its discretion and which may
provide for the selection of a portion or portions (equal to $25 or any integral
multiple thereof) of the principal amount of such Debentures of a denomination
larger than $25, the Debentures to be redeemed and shall thereafter promptly
notify the Company in writing of the numbers of the Debentures to be redeemed,
in whole or in part.

                  The Company may, if and whenever it shall so elect in
accordance with the terms of any series of Debentures established pursuant to
Section 2.01, by delivery of
<PAGE>   36
                                                                              23


instructions signed on its behalf by its President or any Vice President,
instruct the Trustee or any paying agent to call all or any part of the
Debentures of a particular series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable. In any case in which notice of redemption is to be given by the
Trustee or any such paying agent, the Company shall deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be, such Debenture Register, transfer books or other records or
suitable copies or extracts therefrom, sufficient to enable the Trustee or such
paying agent to give any notice by mail that may be required under the
provisions of this Section.

                  SECTION 3.03. (a) If the giving of notice of redemption shall
have been completed as above provided, the Debentures or portions of Debentures
of the series to be redeemed specified in such notice shall become due and
payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to but not including the date
fixed for redemption and interest on such Debentures or portions of Debentures
shall cease to accrue on and after the date fixed for redemption, unless the
Company shall default in the payment of such redemption price and accrued
interest with respect to any such Debenture or portion thereof. On presentation
and surrender of such Debentures on or after the date fixed for redemption at
the place of payment specified in the notice, said Debentures shall be paid and
redeemed at the applicable redemption price for such series, together with
interest accrued thereon to but not including the date fixed for redemption (but
if the date fixed for redemption is after the record date with respect to an
Interest Payment Date and on or prior to such Interest Payment Date, the
interest installment payable on such Interest Payment Date shall be payable to
the registered holder at the close of business on the applicable record date
pursuant to Section 2.03).

                  (b) Upon presentation of any Debenture of such series which is
to be redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Debenture is presented shall
make available for delivery to the holder thereof, at the expense of the
Company, a new Debenture or Debentures of the same series, of authorized
denominations in principal amount
<PAGE>   37
                                                                              24


equal to the unredeemed portion of the Debenture so presented.

                  SECTION 3.04. The provisions of Sections 3.04, 3.05 and 3.06
shall be applicable to any sinking fund for the retirement of Debentures of a
series, except as otherwise specified as contemplated by Section 2.01 for
Debentures of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Debentures of any series is herein referred to as a "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the terms of Debentures of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms of Debentures for
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 3.05. Each sinking fund payment shall be
applied to the redemption of Debentures of any series as provided for by the
terms of Debentures of such series.

                  SECTION 3.05. The Company (i) may deliver Outstanding
Debentures of a series (other than any previously called for redemption) and
(ii) may apply as a credit Debentures of a series which have been redeemed,
either at the election of the Company pursuant to the terms of such Debentures
or through the application of permitted optional sinking fund payments pursuant
to the terms of such Debentures, in each case in satisfaction of all or any part
of any sinking fund payment with respect to the Debentures of such series
required to be made pursuant to the terms of such Debentures as provided for by
the terms of such series; provided that such Debentures have not been previously
so credited. Such Debentures shall be received and credited for such purpose by
the Trustee at the redemption price specified in such Debentures for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

                  SECTION 3.06. Not less than 45 days prior to each sinking fund
payment date for any series of Debentures, the Company (i) will deliver to the
Trustee an Officers' Certificate specifying (x) the amount of the next ensuing
sinking fund payment for that series pursuant to the terms of such series, and
(y) the portion thereof, if any, which is to be satisfied by delivering and
crediting Debentures of such series pursuant to Section 3.05 and the basis for
such
<PAGE>   38
                                                                              25


credit and (ii) will, together with such Officers' Certificate, deliver to the
Trustee any Debentures to be so delivered. Not less than 30 days before each
such sinking fund payment date, the Trustee shall select the Debentures to be
redeemed upon such sinking fund payment date in the manner specified in Section
3.02 and cause notice of the redemption thereof to be given in the name and at
the expense of the Company in the manner provided in Section 3.02. Such notice
having been duly given, the redemption of such Debentures shall be made upon the
terms and in the manner stated in Section 3.03.


                                   ARTICLE IV

                       Particular Covenants of the Company

                  The Company covenants and agrees for each series of the
Debentures as follows:

                  SECTION 4.01. The Company will duly and punctually pay or
cause to be paid the principal of (and premium, if any), and interest on, the
Debentures of such series at the time and place and in the manner provided
herein and established with respect to such Debentures.

                  SECTION 4.02. So long as any series of the Debentures remain
Outstanding, the Company agrees to maintain an office or agency in the Borough
of Manhattan, The City and State of New York, with respect to each such series
and at such other location or locations as may be designated as provided in this
Section 4.02, where (i) Debentures of that series may be presented for payment,
(ii) Debentures of that series may be presented as hereinabove authorized for
registration of transfer and exchange, and (iii) notices and demands to or upon
the Company in respect of the Debentures of that series and this Indenture may
be given or served, such designation to continue with respect to such office or
agency until the Company shall, by written notice signed by its President or a
Vice President and delivered to the Trustee, designate some other office or
agency for any or all of such purposes. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints
<PAGE>   39
                                                                              26


the Trustee as its agent to receive all such presentations, notices and demands.

                  SECTION 4.03. (a) If the Company shall appoint one or more
paying agents for all or any series of the Debentures, other than the Trustee,
the Company will cause each such paying agent to execute and deliver to the
Trustee an instrument in which such paying agent shall agree with the Trustee,
subject to the provisions of this Section:

                  (1) that it will hold all sums held by it as such agent for
         the payment of the principal of (and premium, if any), or interest on,
         the Debentures of that series (whether such sums have been paid to it
         by the Company or by any other obligor of such Debentures) in trust for
         the benefit of the persons entitled thereto;

                  (2) that it will give the Trustee written notice of any
         failure by the Company (or by any other obligor of such Debentures) to
         make any payment of the principal of (and premium, if any), or interest
         on, the Debentures of that series when the same shall be due and
         payable;

                  (3) that it will, at any time during the continuance of any
         failure referred to in the preceding paragraph (a)(2) above, upon the
         written request of the Trustee, forthwith pay to the Trustee all sums
         so held in trust by such paying agent; and

                  (4) that it will perform all other duties of paying agent as
         set forth in this Indenture.

                  (b) If the Company shall act as its own paying agent with
respect to any series of the Debentures, it will, on or before each due date of
the principal of (and premium, if any), or interest on, Debentures of that
series, set aside, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay such principal (and premium, if any) or
interest so becoming due on Debentures of that series until such sums shall be
paid to such Persons or otherwise disposed of as herein provided and will
promptly notify the Trustee in writing of such action, or any failure (by it or
any other obligor on such Debentures) to take such action. Whenever the Company
shall have one or more paying agents for any series of Debentures, it will,
prior to each due date of the principal of (and premium, if any), or interest
on, any Debentures of that
<PAGE>   40
                                                                              27


series, deposit with the paying agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such paying agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

                  (c) Anything in this Section to the contrary notwithstanding,
(i) the agreement to hold sums in trust as provided in this Section is subject
to the provisions of Section 11.04 and (ii) the Company may at any time, for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other purpose, pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying agent, such sums to be held by the
Trustee upon the same terms and conditions as those upon which such sums were
held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.

                  SECTION 4.04. The Company, whenever necessary to avoid or fill
a vacancy in the office of Trustee, will appoint, in the manner provided in
Section 7.10, a Trustee, so that there shall at all times be a Trustee
hereunder.


                                    ARTICLE V

                       Debentureholders Lists and Reports
                         by the Company and the Trustee

                  SECTION 5.01. The Company will furnish or cause to be
furnished to the Trustee (a) on a monthly basis on each regular record date (as
defined in Section 2.03) a list, in such form as the Trustee may reasonably
require, of the names and addresses of the holders of each series of Debentures
as of such regular record date; provided that the Company shall not be obligated
to furnish or cause to be furnished such list at any time that the list shall
not differ in any respect from the most recent list furnished to the Trustee by
the Company and (b) at such other times as the Trustee may request in writing
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time
such list is furnished; provided, however,
<PAGE>   41
                                                                              28


that no such list need be furnished for any series for which the Trustee shall
be the Debenture Registrar.

                  SECTION 5.02. (a) The Trustee shall preserve, in as current a
form as is reasonably practicable, all information as to the names and addresses
of the holders of Debentures contained in the most recent list furnished to it
as provided in Section 5.01 and as to the names and addresses of holders of
Debentures received by the Trustee in its capacity as Debenture Registrar (if
acting in such capacity).

                  (b) The Trustee may destroy any list furnished to it as
provided in Section 5.01 upon receipt of a new list so furnished.

                  (c) In case three or more holders of Debentures of a series
(hereinafter referred to as "applicants") apply in writing to the Trustee, and
furnish to the Trustee reasonable proof that each such applicant has owned a
Debenture for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other holders of Debentures of such series or holders of all
Debentures with respect to their rights under this Indenture or under such
Debentures, and such application is accompanied by a copy of the form of proxy
or other communication which such applicants propose to transmit, then the
Trustee shall within five business days after the receipt of such application,
at its election, either:

                  (1) afford to such applicants access to the information
         preserved at the time by the Trustee in accordance with the provisions
         of subsection (a) of this Section 5.02; or

                  (2) inform such applicants as to the approximate number of
         holders of Debentures of such series or of all Debentures, as the case
         may be, whose names and addresses appear in the information preserved
         at the time by the Trustee, in accordance with the provisions of
         subsection (a) of this Section 5.02, and as to the approximate cost of
         mailing to such Debentureholders the form of proxy or other
         communication, if any, specified in such application.

                  (d)  If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall,
<PAGE>   42
                                                                              29


upon the written request of such applicants, mail to each holder of such series
or of all Debentures, as the case may be, whose name and address appears in the
information preserved at the time by the Trustee in accordance with the
provisions of subsection (a) of this Section 5.02, a copy of the form of proxy
or other communication which is specified in the application of such applicants
received pursuant to subsection (c) of this Section 5.02, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of mailing,
unless within five days after such tender, the Trustee shall mail to such
applicants and file with the Securities and Exchange Commission (the
"Commission"), together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the holders of Debentures of such series or
of all Debentures, as the case may be, or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such
Debentureholders with reasonable promptness after the entry of such order and
the renewal of such tender; otherwise, the Trustee shall be relieved of any
obligation or duty to such applicants respecting their application.

                  (e) Each and every holder of the Debentures, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any paying agent nor any Debenture Registrar shall
be held accountable by reason of the disclosure of any such information as to
the names and addresses of the holders of Debentures in accordance with the
provisions of this Section, regardless of the source from which such information
was derived, and that the Trustee shall not be held accountable by reason of
mailing any material pursuant to a request made under this Section.

                  SECTION 5.03. (a) The Company covenants and agrees to file
with the Trustee, within 15 days after the Company is required to file the same
with the Commission,
<PAGE>   43
                                                                              30


copies of the annual reports and of the information, documents and other reports
(or copies of such portions of any of the foregoing as the Commission may from
time to time by rules and regulations prescribe) which the Company may be
required to file with the Commission pursuant to Section 13 or Section 15(d) of
the Exchange Act; or, if the Company is not required to file information,
documents or reports pursuant to either of such Sections, then to file with the
Trustee and the Commission in accordance with the rules and regulations
prescribed from time to time by the Commission, such of the supplementary and
periodic information, documents and reports which may be required pursuant to
Section 13 of the Exchange Act, in respect of a security listed and registered
on a national securities exchange, as may be prescribed from time to time in
such rules and regulations. Delivery of such reports, information and documents
to the Trustee is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive notice of any information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

                  (b) The Company covenants and agrees to file with the Trustee
and the Commission, in accordance with the rules and regulations prescribed from
time to time by the Commission, such additional information, documents and
reports with respect to compliance by the Company with the conditions and
covenants provided for in this Indenture as may be required from time to time by
such rules and regulations.

                  (c) The Company covenants and agrees to transmit by mail,
first class postage prepaid, or by reputable overnight delivery service which
provides for evidence of receipt, to the Debentureholders, as their names and
addresses appear upon the Debenture Register, within 30 days after the filing
thereof with the Trustee, such summaries of any information, documents and
reports required to be filed by the Company pursuant to subsections (a) and (b)
of this Section as may be required by rules and regulations prescribed from time
to time by the Commission.

                  (d) The Company covenants and agrees to furnish to the
Trustee, on or before May 15 in each calendar year in which any of the
Debentures are Outstanding, or on or before such other day in each calendar year
as the Company and the Trustee may from time to time agree upon, a Certificate
of

                                                                              31


the principal executive officer, principal financial officer, or principal
accounting officer as to his or her knowledge of the Company's compliance with
all conditions and covenants under this Indenture. For purposes of this
subsection (d), such compliance shall be determined without regard to any period
of grace or requirement of notice provided under this Indenture.

                  SECTION 5.04. (a) On or before July 15 in each year in which
any of the Debentures are Outstanding, the Trustee shall transmit by mail, first
class postage prepaid, to the Debentureholders, as their names and addresses
appear upon the Debenture Register, a brief report dated as of the preceding May
15, with respect to any of the following events which may have occurred within
the previous 12 months (but if no such event has occurred within such period no
report need be transmitted):

                  (1) any change to its eligibility under Section 7.09, and its
         qualifications under Section 7.08;

                  (2) the creation of, or any material change to, a relationship
         specified in paragraphs (1) through (10) of subsection (c) of Section
         7.08;

                  (3) the character and amount of any advances (and if the
         Trustee elects so to state, the circumstances surrounding the making
         thereof) made by the Trustee (as such) which remain unpaid on the date
         of such report, and for the reimbursement of which it claims or may
         claim a lien or charge, prior to that of the Debentures, on any
         property or funds held or collected by it as Trustee if such advances
         so remaining unpaid aggregate more than 1/2 of 1% of the principal
         amount of the Debentures outstanding, determined in accordance with
         Section 8.04, on the date of such report;

                  (4) any change to the amount, interest rate, and maturity date
         of all other indebtedness owing by the Company, or by any other obligor
         on the Debentures, to the Trustee in its individual capacity, on the
         date of such report, with a brief description of any property held as

                  (5) any change to the property and funds, if any, physically
         in the possession of the Trustee as such on the date of such report;

                  (6) any release, or release and substitution, of property
         subject to the lien of this Indenture (and the consideration thereof,
         if any) which it has not previously reported;

                  (7) any additional issue of Debentures which the Trustee has
         not previously reported; and

                  (8) any action taken by the Trustee in the performance of its
         duties under this Indenture which it has not previously reported and
         which in its opinion materially affects the Debentures or the
         Debentures of any series, except any action in respect of a default,
         notice of which has been or is to be withheld by it in accordance with
         the provisions of Section 6.07.

                  (b) The Trustee shall transmit by mail, first class postage
prepaid, to the Debentureholders, as their names and addresses appear upon the
Debenture Register, a brief report with respect to the character and amount of
any advances (and if the Trustee elects so to state, the circumstances
surrounding the making thereof) made by the Trustee as such since the date of
the last report transmitted pursuant to the provisions of subsection (a) of this
Section (or if no such report has yet been so transmitted, since the date of
execution of this Indenture), for the reimbursement of which it claims or may
claim a lien or charge prior to that of the Debentures of any series on property
or funds held or collected by it as Trustee, and which it has not previously
reported pursuant to this subsection if such advances remaining unpaid at any
time aggregate more than 10% of the principal amount of Debentures of such
series outstanding, determined in accordance with Section 8.04, at such time,
such report to be transmitted within 90 days after such advances.

                  (c) A copy of each such report shall, at the time of such
transmission to Debentureholders, be filed by the Trustee with the Company, with
each stock exchange upon which any Debentures are listed (if so listed) and also
with the Commission. The Company agrees to notify the Trustee when any
Debentures become listed on any stock exchange.

                           REMEDIES OF THE TRUSTEE AND
                      DEBENTUREHOLDERS ON EVENT OF DEFAULT

                  SECTION 6.01. (a) Whenever used herein with respect to
Debentures of a particular series, "Event of Default" means any one or more of
the following events which has occurred and is continuing:

                  (1) default in the payment of any installment of interest upon
         any of the Debentures of that series, as and when the same shall become
         due and payable, and continuance of such default for a period of 30
         days; provided, however, that a valid extension of an interest payment
         period by the Company in accordance with the terms of any indenture
         supplemental hereto, shall not constitute a default in the payment of
         interest;

                  (2) default in the payment of the principal of (or premium, if
         any, on) any of the Debentures of that series as and when the same
         shall become due and payable whether at maturity, upon redemption, by
         declaration or otherwise, or in any payment required by any sinking or
         analogous fund established with respect to that series;

                  (3) failure on the part of the Company duly to observe or
         perform any other of the covenants or agreements on the part of the
         Company with respect to that series contained in such Debentures or
         otherwise established with respect to that series of Debentures
         pursuant to Section 2.01 or contained in this Indenture (other than a
         covenant or agreement which has been expressly established solely for
         the benefit of one or more series of Debentures other than such series)
         for a period of 90 days after the date on which written notice of such
         failure, requiring the same to be remedied and stating that such notice
         is a "Notice of Default" hereunder, shall have been given to the
         Company by the Trustee, by registered or certified mail, or to the
         Company and the Trustee by the holders of at least 25% in principal
         amount of the Debentures of that series at the time outstanding,
         determined in accordance with Section 8.04;

                  (4) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Company in an

         proceeding under any applicable Federal or State bankruptcy,
         insolvency, reorganization or other similar law or (B) a decree or
         order adjudging the Company a bankrupt or insolvent, or approving as
         properly filed a petition seeking reorganization, arrangement,
         adjustment or composition of or in respect of the Company under any
         applicable Federal or State law, or appointing a custodian, receiver,
         liquidator, assignee, trustee, sequestrator or other similar official
         of the Company or of any substantial part of its property, or ordering
         the winding up or liquidation of its affairs, and the continuance of
         any such decree or order for relief or any such other decree or order
         unstayed and in effect for a period of 90 consecutive days; or

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

                  (b) If an Event of Default occurs and is continuing with
respect to Debentures of a particular series, unless the principal of all the
Debentures of such series shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debentures of that series then outstanding hereunder, determined in accordance
with Section 8.04, by notice in writing to the Company (and to
<PAGE>   48
                                                                              35


the Trustee if given by such Debentureholders), may declare the principal of all
the Debentures of that series to be due and payable immediately, and upon any
such declaration the same shall become and shall be immediately due and payable,
anything contained in this Indenture or in the Debentures of that series or
established with respect to that series pursuant to Section 2.01 to the contrary
notwithstanding.

                  (c) Section 6.01(b), however, is subject to the condition that
if, at any time after the principal of the Debentures of a series shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Debentures
of such series and the principal of (and premium, if any, on) any and all
Debentures of that series which shall have become due otherwise than by
acceleration (with interest upon such principal (and premium, if any), and, to
the extent that such payment is enforceable under applicable law, upon overdue
installments of interest, at the rate per annum expressed in the Debentures of
such series to the date of such payment or deposit) and the amount payable to
the Trustee under Section 7.06, and any and all defaults under the Indenture,
other than the nonpayment of principal on Debentures of such series which shall
not have become due by their terms, shall have been remedied or waived as
provided in Section 6.06, then the holders of a majority in aggregate principal
amount of the Debentures of such series then outstanding, determined in
accordance with Section 8.04, (subject to, in the case of any series of
Debentures held as trust assets of a PWG Capital Trust and with respect to which
a Security Exchange has not theretofore occurred, such consent of the holders of
the Preferred Securities and the Common Securities of such PWG Capital Trust as
may be required under the Declaration of Trust of such PWG Capital Trust), by
written notice to the Company and to the Trustee, may rescind and annul such
declaration and its consequences with respect to such series of Debentures; but
no such rescission and annulment shall extend to or shall affect any subsequent
default, or shall impair any right consequent thereon.

                  (d) In case the Trustee shall have proceeded to enforce any
right with respect to Debentures of a series under this Indenture and such
proceedings shall have been discontinued or abandoned because of rescission or
annulment
<PAGE>   49
                                                                              36


as provided in (c) above or for any other reason or shall have been determined
adversely to the Trustee, then the Company and the Trustee shall be restored to
their former respective positions and rights hereunder, and all rights, remedies
and powers of the Company and the Trustee shall continue as though no such
proceedings had been taken.

                  (e) If, prior to a Security Exchange with respect to the
Debentures of any series, a Default with respect to the Debentures of such
series shall have occurred, the Company expressly acknowledges that under the
circumstances set forth in the applicable Declaration of Trust, any holder of
Preferred Securities of the applicable PWG Capital Trust may enforce directly
against the Company the applicable Property Trustee's rights hereunder. In
furtherance of the foregoing and for the avoidance of any doubt, the Company
acknowledges that, under the circumstances described in the applicable
Declaration of Trust, any such holder of Preferred Securities, in its own name,
in the name of the applicable PWG Capital Trust or in the name of the holders of
the Preferred Securities issued by such PWG Capital Trust, may institute or
cause to be instituted a proceeding, including, without limitation, any suit in
equity, an action at law or other judicial or administrative proceeding, to
enforce the applicable Property Trustee's rights hereunder directly against the
Company as issuer of the applicable series of Debentures, and may prosecute such
proceeding to judgment or final decree, and enforce the same against the
Company.

                  SECTION 6.02. (a) The Company covenants that (1) in case
default shall be made in the payment of any installment of interest on any of
the Debentures of a series, or any payment required by any sinking or analogous
fund established with respect to such series as and when the same shall have
become due and payable, and such default shall have continued for a period of 30
days, or (2) in case default shall be made in the payment of the principal of
(or premium, if any, on) any of the Debentures of a series when the same shall
have become due and payable, whether upon maturity of the Debentures of a series
or upon redemption or upon declaration or otherwise, then, upon demand of the
Trustee, the Company will pay to the Trustee, for the benefit of the holders of
the Debentures of such series, the whole amount that then shall have become due
and payable on all Debentures of such series for principal (and premium, if any)
or interest, or both, as the case may be, with interest upon the overdue
principal (and premium, if any) and (to the
<PAGE>   50
                                                                              37


extent that payment of such interest is enforceable under applicable law and
without duplication of any other amounts paid by the Company in respect thereof)
upon overdue installments of interest at the rate per annum expressed in the
Debentures of such series; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 7.06.

                  (b) In case the Company shall fail forthwith to pay such
amounts upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any action or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company or
other obligor upon the Debentures of such series and collect in the manner
provided by law out of the property of the Company or other obligor upon the
Debentures of such series wherever situated the moneys adjudged or decreed to be
payable.

                  (c) In case of any receivership, insolvency, liquidation,
bankruptcy, reorganization, readjustment, arrangement, composition or other
judicial proceedings affecting the Company, any other obligor on the Debentures
of any series, or the creditors or property of either, the Trustee shall have
the power to intervene in such proceedings and take any action therein that may
be permitted by the court and shall (except as may be otherwise provided by law)
be entitled to file such proofs of claim and other papers and documents as may
be necessary or advisable in order to have the claims of the Trustee and of the
holders of Debentures of such series allowed for the entire amount due and
payable by the Company or such other obligor under the Indenture at the date of
institution of such proceedings and for any additional amount which may become
due and payable by the Company or such other obligor after such date, and to
collect and receive any moneys or other property payable or deliverable on any
such claim, and to distribute the same after the deduction of the amount payable
to the Trustee under Section 7.06; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the holders of
Debentures of such series to make such payments to the Trustee, and, in the
event that the Trustee shall consent to the making of such payments directly to
such Debentureholders, to pay to the Trustee any amount due it under Section
7.06.

                                                                              38


                  (d) All rights of action and of asserting claims under this
Indenture, or under any of the terms established with respect to Debentures of
any series, may be enforced by the Trustee without the possession of any of such
Debentures, or the production thereof at any trial or other proceeding relative
thereto, and any such suit or proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for payment to the Trustee of any amounts due
under Section 7.06, be for the ratable benefit of the holders of the Debentures
of such series.

                  In case of an Event of Default hereunder, the Trustee may in
its discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Debentureholder any plan of reorganization, arrangement, adjustment or
composition affecting the Debentures of any series or the rights of any holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Debentureholder in any such proceeding.

                  SECTION 6.03. Any moneys collected by the Trustee pursuant to
Section 6.02 with respect to a particular series of Debentures shall be applied
in the following order, at the date or dates fixed by the Trustee and, in case
of the distribution of such moneys on account of principal (or premium, if any)
or interest, upon presentation of the Debentures of such series, and stamping
thereon the payment, if only partially paid, and upon surrender thereof if fully
paid:

                  FIRST: To the payment of costs and expenses of collection and
         of all amounts payable to the Trustee under Section 7.06;
<PAGE>   52
                                                                              39


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

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto.

                  SECTION 6.04. No holder of any Debenture of any series shall
have any right by virtue or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless such holder previously shall have
given to the Trustee written notice of an Event of Default and of the
continuance thereof with respect to Debentures of such series specifying such
Event of Default, as hereinbefore provided, and unless also the holders of not
less than 25% in aggregate principal amount of the Debentures of such series
then outstanding, determined in accordance with Section 8.04, shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity, shall have failed to
institute any such action, suit or proceeding; it being understood and intended,
and being expressly covenanted by the holders and the Trustee, that no one or
more holders of Debentures of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of the holders of any other of such
Debentures, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Debentures of such series. For the protection and enforcement of the
provisions of this Section, each and every Debentureholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

                                                                              40


                  Notwithstanding any other provisions of this Indenture,
however, the right of any holder of any Debenture to receive payment of the
principal of (and premium, if any) and interest on such Debenture, as therein
provided, on or after the respective due dates expressed in such Debenture (or
in the case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder. In
addition, as set forth in the Declaration, any holder of Preferred Securities
shall have the right to institute suit for the enforcement of any such payment
to such holder with respect to Debentures having a principal amount equal to the
aggregate liquidation preference of the Preferred Securities held by such
holder.

                  SECTION 6.05. (a) All powers and remedies given by this
Article to the Trustee or to the Debentureholders shall, to the extent permitted
by law, be deemed cumulative and not exclusive of any others thereof or of any
other powers and remedies available to the Trustee or the holders of the
Debentures, by judicial proceedings or otherwise, to enforce performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Debentures.

                  (b) No delay or omission by the Trustee or by any holder of
any of the Debentures to exercise any right or power accruing upon any Event of
Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to the provisions of Section 6.04, every
power and remedy given by this Article or by law to the Trustee or to the
Debentureholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Debentureholders.

                  SECTION 6.06. The holders of a majority in aggregate principal
amount of the Debentures of any series at the time outstanding, determined in
accordance with Section 8.04 (with, in the case of any series of Debentures held
as trust assets of a PWG Capital Trust and with respect to which a Security
Exchange has not theretofore occurred, such consent of holders of the Preferred
Securities and the Common Securities of such PWG Capital Trust as may be
required under the Declaration of Trust of such PWG Capital Trust), shall have
the right to direct the time, method and

                                                                            41
                                                           
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee with respect to such
series; provided, however, that such direction shall not be in conflict with any
rule of law or with this Indenture or unduly prejudicial to the rights of
holders of Debentures of any other series at the time outstanding (determined in
accordance with Section 8.04) and not parties thereto. Subject to the provisions
of Section 7.01, the Trustee shall have the right to decline to follow any such
direction if the Trustee in good faith shall, by a Responsible Officer or
Responsible Officers of the Trustee, determine that the proceeding so directed
would involve the Trustee in personal liability. The holders of a majority in
aggregate principal amount of the Debentures of any series at the time
outstanding, determined in accordance with Section 8.04, affected thereby,
determined in accordance with Section 8.04 (with, in the case of any series of
Debentures held as trust assets of a PWG Capital Trust and with respect to which
a Security Exchange has not theretofore occurred, such consent of holders of the
Preferred Securities and the Common Securities of such PWG Capital Trust as may
be required under the Declaration of Trust of such PWG Capital Trust), may, on
behalf of the holders of all of the Debentures of such series, waive any past
default in the performance of any of the covenants contained herein or
established pursuant to Section 2.01 with respect to such series and its
consequences, except a default in the payment of the principal of, or premium,
if any, or interest on, any of the Debentures of such series as and when the
same shall become due (x) by the terms of such Debentures otherwise than by
acceleration (unless such default has been cured and a sum sufficient to pay all
matured installments of interest and principal and any premium has been
deposited with the Trustee (in accordance with Section 6.01(c)) or (y) as a
result of a call for redemption of Debentures of such series. Upon any such
waiver, the default covered thereby shall be deemed to be cured for all purposes
of this Indenture and the Company, the Trustee and the holders of the Debentures
of such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

         SECTION 6.07. The Trustee shall, within 90 days after the occurrence of
a default with respect to a particular series, transmit by mail, first-class
postage prepaid, to the holders of Debentures of such series, as
<PAGE>   55
                                                                             42

their names and addresses appear upon the Debenture Register, notice of all
defaults with respect to such series known to the Trustee, unless such defaults
shall have been cured before the giving of such notice (the term "defaults" for
the purpose of this Section being hereby defined to be the events specified in
subsections (1), (2), (3), (4) and (5) of Section 6.01(a), not including any
periods of grace provided for therein and irrespective of the giving of notice
provided for by subsection (3) of Section 6.01(a)); provided that, except in the
case of default in the payment of the principal of (or premium, if any), or
interest on, any of the Debentures of such series or in the payment of any
sinking fund installment established with respect to such series, the Trustee
shall be protected in withholding such notice if and so long as the Board of
Directors, the executive committee, or a trust committee of directors and/or
Responsible Officers, of the Trustee in good faith determine that the
withholding of such notice is in the interests of the holders of Debentures of
such series; provided further, however, that, in the case of any default of the
character specified in Section 6.01(a)(3) with respect to Debentures of such
series, no such notice to the holders of the Debentures of such series shall be
given until at least 30 days after the occurrence thereof.

         The Trustee shall not be deemed to have knowledge of any default,
except (i) a default under subsection (a)(1) or (a)(2) of Section 6.01 as long
as the Trustee is acting as paying agent for such series of Debentures or (ii)
any default as to which the Trustee shall have received written notice or a
Responsible Officer shall have obtained written notice.

         SECTION 6.08. All parties to this Indenture agree, and each holder of
any Debentures by his or her acceptance thereof shall be deemed to have agreed,
that any court may in its discretion require, in any suit for the enforcement of
any right or remedy under this Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, or by any Debentureholder, or group of Debentureholders, holding

                                                                             43

more than 10% in aggregate principal amount of the Debentures of any series at
the time outstanding, determined in accordance with Section 8.04, or to any suit
instituted by any Debentureholder for the enforcement of the payment of the
principal of (premium, if any), or interest on, any Debenture of such series, on
or after the respective due dates expressed in such Debenture or established
pursuant to this Indenture.

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


                                   ARTICLE VII

                             Concerning the Trustee

         SECTION 7.01. (a) The Trustee, prior to the occurrence of an Event of
Default with respect to Debentures of a series and after the curing of all
Events of Default with respect to Debentures of that series which may have
occurred, shall undertake to perform with respect to Debentures of such series
such duties and only such duties as are specifically set forth in this
Indenture, and no implied covenants shall be read into this Indenture against
the Trustee. In case an Event of Default with respect to Debentures of a series
has occurred (which has not been cured or waived), the Trustee shall exercise
with respect to Debentures of that series such of the rights and powers vested
in it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

         (b) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that:
<PAGE>   57
                                                                            44

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

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

                         (ii) in the absence of bad faith on the part of the
                  Trustee, the Trustee may with respect to Debentures of such
                  series conclusively rely, as to the truth of the statements
                  and the correctness of the opinions expressed therein, upon
                  any certificates or opinions furnished to the Trustee and
                  conforming to the requirements of this Indenture; but in the
                  case of any such certificates or opinions which by any
                  provision hereof are specifically required to be furnished to
                  the Trustee, the Trustee shall be under a duty to examine the
                  same to determine whether or not they conform to the
                  requirements of this Indenture but need not confirm or
                  investigate the accuracy of mathematical calculations or other
                  facts stated therein;

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

         (3) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
holders of a majority in principal amount of the Debentures of any series at the
time outstanding, determined in accordance with Section 8.04, relating to the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred upon the Trustee under
<PAGE>   58
                                                                            45

this Indenture with respect to the Debentures of such series;

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

                  (5) whether or not therein expressly so provided, every
         provision of this Indenture relating to the conduct or affecting the
         liability of or affording protection to the Trustee shall be subject to
         the provisions of this Article VII.

                  SECTION 7.02.  Except as otherwise provided in
Section 7.01:

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

                  (b) any request, direction, order or demand of the Company
         mentioned herein shall be sufficiently evidenced by a Board Resolution
         or an instrument signed in the name of the Company by the Chairman or
         the Vice Chairman of the Board of Directors or the President or any
         Vice President and by the Secretary or any Assistant Secretary or the
         Treasurer or any Assistant Treasurer or the Controller or any Assistant
         Controller (unless other evidence in respect thereof is specifically
         prescribed herein);

                  (c) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically
<PAGE>   59
                                                                            46

         prescribed) may in the absence of bad faith on its part, rely upon an 
         Officer's Certificate;

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

                  (e) the Trustee shall be under no obligations to exercise any
         of the rights or powers vested in it by this Indenture at the request,
         order or direction of any of the Debentureholders, pursuant to the
         provisions of this Indenture, unless such Debentureholders shall have
         offered to the Trustee reasonable security or indemnity against the
         costs, expenses and liabilities which may be incurred therein or
         thereby; nothing herein contained shall, however, relieve the Trustee
         of the obligation, upon the occurrence of an Event of Default with
         respect to a series of the Debentures (which has not been cured or
         waived) to exercise with respect to Debentures of that series such of
         the rights and powers vested in it by this Indenture, and to use the
         same degree of care and skill in their exercise, as a prudent man would
         exercise or use under the circumstances in the conduct of his own
         affairs;

                  (f) the Trustee shall not be liable for any action taken or
         omitted to be taken by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture;

                  (g) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, approval, bond, security, or other papers or documents, unless
         requested in writing so to do by the holders of not less than a
         majority in principal amount of the Debentures of the particular series
         outstanding affected thereby, determined in accordance with Section 
         8.04; provided, however, that if the payment within a reasonable time
         to the Trustee of the costs, expenses or liabilities likely to be
         incurred by it in the making of such investigation is, in the opinion
         of the Trustee, not reasonably assured to the Trustee 
<PAGE>   60
                                                                            47

         by the security afforded to it by the terms of this Indenture, the 
         Trustee may require reasonable indemnity against such costs, expenses 
         or liabilities as a condition to so proceeding. The reasonable
         expense of every such examination shall be paid by the Company or, if
         paid by the Trustee, shall be repaid by the Company
         upon demand; if the Trustee makes such investigation, it shall be
         entitled to examine the books, records and premises of the Company,
         personally or by agent or attorney; and

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

                  SECTION 7.03. (a) The recitals contained herein and in the
Debentures (other than the Certificate of Authentication on the Debentures)
shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.

                  (b)  The Trustee makes no representations as to the validity 
or sufficiency of this Indenture or of the Debentures.

                  (c) The Trustee shall not be accountable for the use or
application by the Company of any of the Debentures or of the proceeds of such
Debentures, or for the use or application of any moneys paid over by the Trustee
in accordance with any provision of this Indenture or established pursuant to
Section 2.01, or for the use or application of any moneys received by any paying
agent other than the Trustee.

                  SECTION 7.04. The Trustee or any paying agent or Debenture
Registrar, in its individual or any other capacity, may become the owner or
pledgee of Debentures with the same rights it would have if it were not Trustee,
paying agent or Debenture Registrar.

                  SECTION 7.05. Subject to the provisions of Section 11.04, all
moneys received by the Trustee shall until used or applied as herein provided,
be held in trust for the purposes for which they were received, but need not be
segregated from other funds except to the extent required
<PAGE>   61
                                                                            48

by law. The Trustee shall be under no liability for interest on any moneys
received by it hereunder except such as it may agree with the Company to pay
thereon.

                  SECTION 7.06. (a) The Company covenants and agrees to pay to
the Trustee from time to time, and the Trustee shall be entitled to, such
reasonable compensation as the Company and the Trustee shall from time to time
agree in writing (which shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust) for all services rendered
by it in the execution of the trusts hereby created and in the exercise and
performance of any of the powers and duties hereunder of the Trustee, and the
Company will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence or bad faith. The Company also
covenants to indemnify the Trustee (and its officers, agents, directors and
employees) for, and to hold it harmless against, any loss, liability or expense
including taxes (other than taxes based upon, measured by or determined by the
income of the Trustee) incurred without negligence or bad faith on the part of
the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim or liability in the premises.

                  (b) The obligations of the Company under this Section to
compensate and indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Debentures upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the holders of particular
Debentures.

                  (c) When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 6.01(4) or (5), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any bankruptcy law.
<PAGE>   62
                                                                            49

                  (d) The Company's obligations under this Section 7.06 shall
survive the resignation or removal of any Trustee, the discharge of the
Company's obligations pursuant to Article XI of this Indenture and/or the
termination of this Indenture.

                  SECTION 7.07. Except as otherwise provided in Section 7.01,
whenever in the administration of the provisions of this Indenture the Trustee
shall deem it necessary or desirable that a matter be proved or established
prior to taking or suffering or omitting to take any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the
Trustee, be deemed to be conclusively proved and established by an Officers'
Certificate delivered to the Trustee and such certificate, in the absence of
negligence or bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken, suffered or omitted to be taken by it under the
provisions of this Indenture in reliance thereon.

                  SECTION 7.08. (a) If the Trustee has or shall acquire any
conflicting interest, as defined in Section 310(b) of the Trust Indenture Act,
with respect to the Debentures of any series and if the Default to which such
conflicting interest relates has not been cured, duly waived or otherwise
eliminated, within 90 days after ascertaining that it has such conflicting
interest, it shall either eliminate such conflicting interest, except as
otherwise provided herein, or resign with respect to the Debentures of such
series in the manner and with the effect specified in Section 7.10 and the
Company shall promptly appoint a successor Trustee in the manner provided
herein.

                  (b) In the event that the Trustee shall fail to comply with
the provisions of subsection (a) of this Section , with respect to the 
Debentures of any series the Trustee shall, within ten days after the 
expiration of such 90-day period, transmit notice of such failure by mail, 
first-class postage prepaid, to the Debentureholders of such series as their 
names and addresses appear upon the Debenture Register.

                  (c) Except in the case of a default in the payment of the
principal of (or premium, if any), or interest on, any Debentures issued under
this Indenture, or in the payment of any sinking or analogous fund installment,
<PAGE>   63
                                                                            50

the Trustee shall not be required to resign as provided by this Section 7.08 if
such Trustee shall have sustained the burden of proving, on application to the
Commission and after opportunity for hearing thereon, that (i) the default under
the Indenture may be cured or waived during a reasonable period and under the
procedures described in such application and (ii) a stay of the Trustee's duty
to resign will not be inconsistent with the interests of Debentureholders. The
filing of such an application shall automatically stay the performance of the
duty to resign until the Commission orders otherwise.

                  Any resignation of the Trustee shall become effective only
upon the appointment of a successor trustee and such successor's acceptance of
such an appointment.

                  SECTION 7.09. There shall at all times be a Trustee with
respect to the Debentures issued hereunder which shall at all times be a
corporation organized and doing business under the laws of the United States of
America or any State or Territory thereof or of the District of Columbia, or a
corporation or other person permitted to act as trustee by the Commission,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least 50 million dollars, and subject to supervision
or examination by Federal, State, Territorial, or District of Columbia
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section , the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. The
Company may not, nor may any Person directly or indirectly controlling,
controlled by, or under common control with the Company, serve as Trustee. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section , the Trustee shall resign immediately in the manner
and with the effect specified in Section 7.10.

                  SECTION 7.10. (a) The Trustee or any successor hereafter
appointed may at any time resign with respect to the Debentures of one or more
series by giving written notice thereof to the Company and by transmitting
notice of resignation by mail, first class postage prepaid, to the
Debentureholders of such series, as their names and addresses appear upon the
Debenture Register. Upon 
<PAGE>   64
                                                                            51

receiving such notice of resignation, the Company shall promptly appoint a
successor trustee with respect to Debentures of such series by written
instrument, in duplicate, executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the resigning Trustee and one copy to
the successor trustee. If no successor trustee shall have been so appointed and
have accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to
Debentures of such series, or any Debentureholder of that series who has been a
bona fide holder of a Debenture or Debentures for at least six months may,
subject to the provisions of Section 6.08, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

                  (b)  In case at any time any of the following
shall occur:

                  (1) the Trustee shall fail to comply with the provisions of
         subsection (a) of Section 7.08 after written request therefor by the
         Company or by any Debentureholder who has been a bona fide holder of a
         Debenture or Debentures for at least six months; or

                  (2) the Trustee shall cease to be eligible in accordance with
         the provisions of Section 7.09 and shall fail to resign after written
         request therefor by the Company or by any such Debentureholder; or

                  (3) the Trustee shall become incapable of acting, or shall be
         adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
         its property shall be appointed, or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation, then, in any
         such case, the Company may remove the Trustee with respect to all
         Debentures and appoint a successor trustee by written instrument, in
         duplicate, executed by order of the Board of Directors, one copy of
         which instrument shall be delivered to the Trustee so removed and one
         copy to the successor trustee. If no successor trustee shall have been
         so appointed and have accepted appointment within 30 days 

<PAGE>   65
                                                                             52

         after the  mailing of such notice of removal, the Trustee so removed 
         may petition any court of competent jurisdiction for the appointment 
         of a successor trustee with respect to Debentures of such series, or 
         any Debentureholder of that series who has been a bona fide holder of a
         Debenture or Debentures for at least six months may, subject to the 
         provisions of Section 6.08, on behalf of himself and all others 
         similarly situated, petition any such court for the removal of the 
         Trustee and the appointment of a successor trustee.  Such court may 
         thereupon after such notice, if any, as it may deem proper and 
         prescribe, remove the Trustee and appoint a successor trustee.

                  (c) The holders of a majority in aggregate principal amount of
the Debentures of any series at the time outstanding, determined in accordance
with Section 8.04, may at any time remove the Trustee with respect to such
series and appoint a successor trustee.

                  (d) Any resignation or removal of the Trustee and appointment
of a successor trustee with respect to the Debentures of a series pursuant to
any of the provisions of this Section shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

                  (e) Any successor trustee appointed pursuant to this Section 
may be appointed with respect to the Debentures of one more series or all such
series, but at any time there shall be only one Trustee with respect to the
Debentures of any particular series.

                  SECTION 7.11. (a) In case of the appointment hereunder of a
successor trustee with respect to all Debentures, such successor trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor trustee all the rights, powers, and trusts of the
retiring Trustee and shall duly

                                                                             53

assign, transfer and deliver to such successor trustee all property and money
held by such retiring Trustee hereunder.

                  (b) In case of the appointment hereunder of a successor
trustee with respect to the Debentures of one or more (but not all) series, the
Company, the retiring Trustee and each successor trustee with respect to the
Debentures of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Debentures of that or those series to which the appointment of such successor
trustee relates, (2) shall contain such provisions as shall be deemed necessary
or desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Debentures of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and that no Trustee shall be responsible
for any act or failure to act on the part of any other Trustee hereunder; and
upon the execution and delivery of such supplemental indenture the resignation
or removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall with respect to the Debentures of that or
those series to which the appointment of such successor trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, and each such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debentures of that or those series
to which the appointment of such successor trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor trustee, to the extent contemplated by
such supplemental indenture, the property

                                                                             54

and money held by such retiring Trustee hereunder with respect to the Debentures
of that or those series to which the appointment of such successor trustee
relates, subject, to the lien, if any, of the retiring Trustee provided for in
Section 7.06.

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

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

                  (e) Upon acceptance of appointment by a successor trustee as
provided in this Section , the Company shall transmit notice of the succession 
of such trustee hereunder by mail, first class postage prepaid, to the 
Debentureholders, as their names and addresses appear upon the Debenture
Register. If the Company fails to transmit such notice within ten days after
acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be transmitted at the expense of the Company.

                  SECTION 7.12. Any corporation into which the Trustee may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be qualified under the provisions of
Section 7.08 and eligible under the provisions of Section 7.09, without the
execution or filing of any paper of any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding. In case any
Debentures shall have been authenticated, but not made available for delivery,
by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and
make available for delivery the Debentures so authenticated with the same effect
as if such successor Trustee had itself authenticated such Debentures.

                  SECTION 7.13. (a) Subject to the provisions of subsection (b)
of this Section , if the Trustee shall be or shall become a creditor, directly 
or indirectly, secured or unsecured, of the Company within three months prior 
to a default, as defined in subsection (b) of this Section , or subsequent to 
such a default, then, unless and until such default shall be cured, the 
Trustee shall set apart and hold in a special account for the benefit of the 
Trustee individually, the holders of the Debentures and the holders of other 
indenture securities (as defined in subsection (c) of this Section ):

                  (1) an amount equal to any and all reductions in the amount
         due and owing upon any claim as such creditor in respect of principal
         or interest, effected after the beginning of such three months' period
         and valid as against the Company and its other creditors, except any
         such reduction resulting from the receipt or disposition of any
         property described in paragraph (2) of this subsection, or from the
         exercise of any right of setoff which the Trustee could have exercised
         if a petition in bankruptcy had been filed by or against the Company
         upon the date of such default; and

                  (2) all property received by the Trustee in respect of any
         claim as such creditor, either as security therefor, or in satisfaction
         or composition thereof, or otherwise, after the beginning of such three
         months' period, or an amount equal to the proceeds of any such
         property, if disposed of, subject, however, to the rights, if any, of
         the Company and its other creditors in such property or such proceeds.

                  Nothing herein contained, however, shall affect the right of
the Trustee:

                  (A) to retain for its own account (i) payments made on account
         of any such claim by any person (other than the Company) who is liable
         thereon, and (ii) the proceeds of the bona fide sale of any such claim
         by the Trustee to a third person, and (iii) distributions made in cash,
         securities, or other property in respect of claims filed against the
         Company in bankruptcy or receivership or in a case for reorganization
         pursuant to the Federal Bankruptcy Code or applicable State law;

                  (B) to realize, for its own account, upon any property held by
         it as security for any such claim, if 
<PAGE>   69
                                                                             56

         such property was so held prior to the beginning of such three month 
         period;

                  (C) to realize, for its own account, but only to the extent of
         the claim hereinafter mentioned, upon any property held by it as
         security for any such claim, if such claim was created after the 
         beginning of such three month period and such property was received as
         security therefor simultaneously with the creation thereof, and if the
         Trustee shall sustain the burden of proving that the time such property
         was so received the Trustee had no reasonable cause to believe that a 
         default, as defined in subsection (c) of this Section , would occur 
         within three months; or

                  (D) to receive payment on any claim referred to in paragraph
         (B) or (C), against the release of any property held as security for
         such claim as provided in such paragraph (B) or (C), as the case may
         be, to the extent of the fair value of such property.

                  For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such three month period for property held as
security at the time of such substitution shall, to the extent of the fair value
of the property released, have the same status as the property released, and, to
the extent that any claim referred to in any of such paragraphs is created in
renewal of or in substitution for or for the purpose of repaying or refunding
any pre-existing claim of the Trustee as such creditor, such claim shall have
the same status as such preexisting claim.

                  If the Trustee shall be required to account, the funds and
property held in such special account and the proceeds thereof shall be
apportioned between the Trustee, the Debentureholders and the holders of other
indenture securities in such manner that the Trustee, the Debentureholders and
the holders of other indenture securities realize, as a result of payments from
such special account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in a case for reorganization pursuant
to the Federal Bankruptcy Code or applicable State law, the same percentage of
their respective claims, figured before crediting to the claim of the Trustee
anything on account of the receipt by it from the Company of the funds and
property in such special account and before crediting to the respective claims
of the Trustee, the Debentureholders and the holders of other 
<PAGE>   70
                                                                             57

indenture securities dividends on claims filed against the Company in bankruptcy
or receivership or in a case for reorganization pursuant to the Federal
Bankruptcy Code or applicable State law, but after crediting thereon receipts on
account of the indebtedness represented by their respective claims from all
sources other than from such dividends and from the funds and property so held
in such special account. As used in this paragraph, with respect to any claim,
the term "dividends" shall include any distribution with respect to such claim,
in bankruptcy or receivership or in a case for reorganization pursuant to the
Federal Bankruptcy Code or applicable State law, whether such distribution is
made in cash, securities, or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such claim. The
court in which such bankruptcy, receivership or a case for reorganization is
pending shall have jurisdiction (i) to apportion between the Trustee, the
Debentureholders and the holders of other indenture securities, in accordance
with the provisions of this paragraph, the funds and property held in such
special account and the proceeds thereof, or (ii) in lieu of such apportionment,
in whole or in part, to give to the provisions of this paragraph due
consideration in determining the fairness of the distributions to be made to the
Trustee, the Debentureholders and the holders of other indenture securities with
respect to their respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

                  Any Trustee who has resigned or been removed after the
beginning of such three month period shall be subject to the provisions of this
subsection (a) as though such resignation or removal had not occurred. If any
Trustee has resigned or been removed prior to the beginning of such three month
period, it shall be subject to the provisions of this subsection (a) if and only
if the following conditions exist:

                  (i) the receipt of property or reduction of claim which would
         have given rise to the obligation to account, if such Trustee had
         continued as trustee, occurred after the beginning of such three month
         period; and
<PAGE>   71
                                                                          58

                (ii) such receipt of property or reduction of claim occurred
         within three months after such resignation or removal.

                  (b) There shall be excluded from the operation of subsection
(a) of this Section a creditor relationship arising from:

                  (1) the ownership or acquisition of securities issued under
         any indenture, or any security or securities having a maturity of one
         year or more at the time of acquisition by the Trustee;

                  (2) advances authorized by a receivership or bankruptcy court
         of competent jurisdiction, or by this Indenture, for the purpose of
         preserving any property other than cash which shall at any time be
         subject to the lien, if any, of this Indenture or of discharging tax
         liens or other prior liens or encumbrances thereon, if notice of such
         advance and of the circumstances surrounding the making thereof is
         given to the Debentureholders at the time and in the manner provided in
         this Indenture;

                  (3) disbursements made in the ordinary course of business in
         the capacity of trustee under an indenture, transfer agent, registrar,
         custodian, paying agent, subscription agent, fiscal agent or
         depositary, or other similar capacity;

                  (4) any indebtedness created as a result of services rendered
         or premises rented; or any indebtedness created as a result of goods or
         securities sold in a cash transaction as defined in subsection (c) of
         this Section ;

                  (5) the ownership of stock or of other securities of a Company
         organized under the provisions of Section 25(a) of the Federal Reserve
         Act, as amended, which is directly or indirectly a creditor of the
         Company; or

                  (6) the acquisition, ownership, acceptance or negotiation of
         any drafts, bills of exchange, acceptance or obligations which fall
         within the classification of self-liquidating paper as defined in
         subsection (c) of this Section .

                  (c)  As used in this Section :

                  (1) The term "default" shall mean any failure to make payment
         in full of the principal of (or premium, if any) or interest upon any 
         of the Debenture or upon the other indenture securities when and as 
         such principal (or premium, if any) or interest becomes due and 
         payable.

                  (2) The term "other indenture securities" shall mean
         securities upon which the Company is an obligor (as defined in the
         Trust Indenture Act) outstanding under any other indenture (A) under
         which the Trustee is also trustee, (B) which contains provisions
         substantially similar to the provisions of subsection (a) of this
         Section , and (C) under which a default exists at the time of the
         apportionment of the funds and property held in said special account.

                  (3) The term "cash transaction" shall mean any transaction in
         which full payment for goods or securities sold is made within seven
         days after delivery of the goods or securities in currency or in checks
         or other orders drawn upon banks or bankers and payable upon demand.

                  (4) The term "self-liquidating paper" shall mean any draft,
         bill of exchange, acceptance or obligation which is made, drawn,
         negotiated or incurred by the Company for the purpose of financing the
         purchase, processing, manufacture, shipment, storage or sale of goods,
         wares or merchandise and which is secured by documents evidencing title
         to, possession of, or a lien upon, the goods, wares or merchandise or
         the receivables or proceeds arising from the sale of the goods, wares
         or merchandise previously constituting the security, provided the
         security is received by the Trustee simultaneously with the creation of
         the creditor relationship with the Company arising from the making,
         drawing, negotiating or incurring of the draft, bill of exchange,
         acceptance or obligation.

                  (5) The term "Company shall mean any obligor upon

                                  ARTICLE VIII

                         Concerning the Debentureholders

                  SECTION 8.01. Whenever in this Indenture it is provided that
the holders of a majority or a specified percentage in aggregate principal
amount of the Debentures of a particular series may take any action (including
the making of any demand or request, the giving of any notice, consent or waiver
or the taking of any other action), the fact that, at the time of taking any
such action, the holders of such majority or specified percentage of such series
have joined therein may be evidenced by any instrument or any number of
instruments of similar terms executed by the holders of Debentures of such
series in person or by agent or proxy appointed in writing and acceptable to the
Trustee.

                  If the Company shall solicit from the Debentureholders of any
series any request, demand, authorization, direction, notice, consent, waiver or
other action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Debentureholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Debentureholders of record at the
close of business on the record date shall be deemed to be Debentureholders for
the purposes of determining whether Debentureholders of the requisite proportion
of outstanding Debentures of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the outstanding Debentures of that series
shall be computed as of the record date; provided that no such authorization,
agreement or consent by such Debentureholders on the record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date.

                  SECTION 8.02. Subject to the provisions of Section 7.01, proof
of the execution of any instrument by a Debentureholder (such proof will not
require notarization) or his agent or proxy and proof of the holding by any
person
<PAGE>   74
                                                                             61

of any of the Debentures shall be sufficient if made in the
following manner:

                  (a) The fact and date of the execution by any such person of
         any instrument may be proved in any reasonable manner acceptable to the
         Trustee.

                  (b) The ownership of Debentures shall be proved by the
         Debenture Register for Debentures of such series or by a certificate of
         the Debenture Registrar with respect thereto.

                  (c) The Trustee may require such additional proof of any
         matter referred to in this Section as it shall deem necessary.

                  SECTION 8.03. Prior to the due presentment for registration of
transfer of any Debenture, the Company, the Trustee, any paying agent and any
Debenture Registrar may deem and treat the person in whose name such Debenture
shall be registered upon the books of the Company as the absolute owner of such
Debenture (whether or not such Debenture shall be overdue and notwithstanding
any notice of ownership or writing thereon made by anyone other than the
Debenture Registrar) for the purpose of receiving payment of, or on account of,
the principal of, premium, if any, and (subject to Section 2.03) interest on,
such Debenture and for all other purposes; and neither the Company nor the
Trustee nor any paying agent nor any Debenture Registrar shall be affected by
any notice to the contrary.

                  SECTION 8.04. In determining whether the holders of the
requisite aggregate principal amount of Debentures of a particular series have
concurred in any direction, consent or waiver under this Indenture, Debentures
of that series which are owned by the Company or any other obligor on the
Debentures of that series or by any Subsidiary of the Company or of such other
obligor on the Debentures of that series shall be disregarded and deemed not to
be outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver, only Debentures of such series which a
Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Debentures so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right so to
<PAGE>   75
                                                                             62

act with respect to such Debentures and that the pledgee is not a person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor. In case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee.

                  SECTION 8.05. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 8.01, of the taking of any
action by the holders of the majority or a specified percentage in aggregate
principal amount of the Debentures of a particular series, any holder of a
Debenture of that series which is shown by the evidence to be included in the
Debentures the holders of which have consented to such action may, by filing
written notice with the Trustee, and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Debenture. Except as
aforesaid any such action taken by the holder of any Debenture shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Debenture, and of any Debenture issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Debenture. Any action
required by the Indenture to be taken, and that is taken, by the holders of the
majority or a specified percentage in aggregate principal amount of the
Debentures of a particular series shall be conclusively binding upon the
Company, the Trustee and the holders of all the Debentures of that series.


                                   ARTICLE IX

                             Supplemental Indentures

                  SECTION 9.01. In addition to any supplemental indenture
otherwise authorized by this Indenture, the Company, when authorized by a Board
Resolution, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act as then in effect), without the consent of
the Debentureholders, for one or more of the following purposes:

                  (a) to evidence the succession of another corporation to the
Company, and the assumption by any
<PAGE>   76
                                                                            63

         such successor of the covenants of the Company contained herein or
         otherwise established with respect to the Debentures of all or any
         series; or

                  (b) to add to the covenants of the Company such further
         covenants, restrictions, conditions or provisions for the protection of
         the holders of the Debentures of all or any series as the Board of
         Directors shall consider to be for the protection of the holders of
         Debentures of all or any series, and to make the occurrence, or the
         occurrence and continuance, of a default in any of such additional
         covenants, restrictions, conditions or provisions an Event of Default
         with respect to such series permitting the enforcement of all or any of
         the several remedies provided in this Indenture as herein set forth;
         provided, however, that in respect of any such additional covenant,
         restriction, condition or provision, such supplemental indenture may
         provide for a particular period of grace after default (which period
         may be shorter or longer than that allowed in the case of other
         defaults) or may provide for an immediate enforcement upon such default
         or may limit the remedies available to the Trustee upon such default or
         may limit the right of the holders of a majority in aggregate principal
         amount of the Debentures of such series to waive such default; or

                  (c) to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture which may
         be defective or inconsistent with any other provision contained herein
         or in any supplemental indenture, or to make such other provisions in
         regard to matters or questions arising under this Indenture as shall
         not be inconsistent with the provisions of this Indenture and shall not
         adversely affect the interests of the holders of the Debentures of any
         series; or

                  (d) to change or eliminate any of the provisions of this
         Indenture, provided that any such change or elimination shall become
         effective only when there is no Debenture outstanding, determined in
         accordance with Section 8.04, of any series created prior to the
         execution of such supplemental indenture which is entitled to the
         benefit of such provision; or
<PAGE>   77
                                                                             64

                  (e) to add to this Indenture such provisions as may be
         expressly permitted by the Trust Indenture Act, excluding, however, the
         provisions referred to in Section 316(a)(2) of the Trust Indenture Act
         as in effect at the date as of which this instrument was executed or
         any corresponding provision in any similar federal statute hereafter
         enacted.

                  The Trustee is hereby authorized to join with the Company in
the execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations which may be therein contained, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

                  Any supplemental indenture authorized by the provisions of
this Section may be executed by the Company and the Trustee without the consent
of the holders of any of the Debentures at the time outstanding, notwithstanding
any of the provisions of Section 9.02.

                  SECTION 9.02. With the consent (evidenced as provided in
Section 8.01) of the holders of not less than a majority in aggregate principal
amount of the Debentures of each series affected by such supplemental indenture
or indentures at the time outstanding, determined in accordance with Section
8.04, (and, in the case of any series of Debentures held as trust assets of a
PWG Capital Trust and with respect to which a Security Exchange has not
theretofore occurred, such consent of holders of the Preferred Securities and
the Common Securities of such PWG Capital Trust as may be required under the
Declaration of Trust of such PWG Capital Trust), the Company, when authorized by
a Board Resolution, and the Trustee may from time to time and at any time enter
into an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act) for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner the
rights of the holders of the Debentures of such series under this Indenture;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Debentures of any series, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any premium payable upon the redemption thereof, without the consent
of the holder of
<PAGE>   78
                                                                             65

each Debenture so affected or (ii) reduce the aforesaid percentage of
Debentures, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of each Debenture
(and, in the case of any series of Debentures held as trust assets of a PWG
Capital Trust and with respect to which a Security Exchange has not theretofore
occurred, such consent of the holders of the Preferred Securities and the Common
Securities of such PWG Capital Trust as may be required under the Declaration of
Trust of such PWG Capital Trust) then outstanding and affected thereby.

                  Upon the request of the Company, accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Debentureholders
(and, in the case of any series of Debentures held as trust assets of PWG
Capital Trust and with respect to which a Security Exchange has not theretofore
occurred, such consent of holders of the Preferred Securities and the Common
Securities of such PWG Capital Trust as may be required under the Declaration of
Trust of such PWG Capital Trust), the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplement indenture.

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

                  Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Debentureholders of all series affected thereby as their names and addresses
appear upon the Debenture Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

                  SECTION 9.03. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article or of Section 10.01, this Indenture
shall, with respect to Debentures of the series affected thereby, be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Debentures of the
series affected thereby shall thereafter be determined, exercised and enforced
hereunder subject to in all respects to such modifications and amendments, and
all the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

                  SECTION 9.04. Debentures of any series, affected by a
supplemental indenture, authenticated and delivered after the execution of such
supplemental indenture pursuant to the provisions of this Article or of Section
10.01, may bear a notation in form approved by the Company, provided such form
meets the requirements of any exchange upon which such series may be listed, as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Debentures of that series so modified as to conform, in the
opinion of the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Debentures of
that series then Outstanding.

                  SECTION 9.05. The Trustee, subject to the provisions of
Section 7.01, may receive an Opinion of Counsel and the other documents, if any,
required by Section 13.06, as conclusive evidence that any supplemental
indenture executed pursuant to this Article is authorized or permitted by, and
conforms to, the terms of this Article and that it is proper for the Trustee
under the provisions of this Article to join in the execution thereof.

same, if

                  (a) with reference to this provision the Company has
         irrevocably deposited or caused to be irrevocably deposited with the
         Trustee as trust funds in trust, specifically pledged as security for,
         and dedicated solely to, the benefit of the holders of the Debentures
         of such series (i) cash in an amount, or (ii) Governmental Obligations
         maturing as to principal and interest at such times and in such amounts
         as will insure the availability of cash or (iii) a combination thereof,

         recognize income, gain or loss for Federal income tax purposes as a
         result of such deposit, defeasance and discharge and will be subject to
         Federal income tax on the same amount and in the same manner and at the
         same times, as would have been the case if such deposit, defeasance and
         discharge had not occurred;

                  (d) the Company has delivered to the Trustee an Officer's
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent provided for relating to the defeasance contemplated by this
         provision have been complied with; and

                  (e) no event or condition shall exist that, pursuant to the
         provisions of Section 14.02 or 14.03, would prevent the Company from
         making payments of the principal of or interest on the Debentures of
         such series on the date of such deposit.

                  SECTION 11.02. Subject to Section 11.04, all moneys deposited

trust and applied by it to the payment, either directly or through any paying
agent (including the Company acting as its own paying agent), to the holders of
the particular Debentures of such series for the payment or redemption of which
such moneys have been deposited with the Trustee, of all sums due and to become
due thereon for principal and interest; but such money need not be segregated
from other funds except to the extent required by law.

                  SECTION 11.03. In connection with the satisfaction and
discharge of this Indenture with respect to Debentures of any series, all moneys
then held by any paying agent under the provisions of this Indenture with
respect to such series of Debentures shall, upon demand of the Company be repaid
to it or paid to the Trustee and thereupon such paying agent shall be released
from all further liability with respect to such moneys.

                  SECTION 11.04. Any moneys deposited with, or paid to, the
Trustee or any paying agent for the payment of principal of, or interest on, any
Debenture of any series and not applied but remaining unclaimed for two years

payable, shall, upon the written request of the Company and unless otherwise
required by mandatory provisions of applicable escheat or abandoned or unclaimed

paying agent, and the holder of any Debentures of such series shall, unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property laws, thereafter look only to the Company for any payment
which such holder may be entitled to collect, and all liability of the Trustee
or any paying agent with respect to such moneys shall thereupon cease; provided,
however, that the Trustee or such paying agent, before being required to make
any such repayment with respect to moneys deposited with it for any payment,
shall, at the expense of the Company, mail by first-class mail to holders of
such Debentures at their addresses as they shall appear on the Debenture
Register, notice that such moneys remain and that, after a date specified
therein, which shall not be less than 30 days from the date of such mailing, any
unclaimed balance of such money then remaining will be repaid to the Company.

                  SECTION 11.05. The Company shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on, or assessed against, the
Governmental Obligations deposited pursuant to Section 11.01 or the principal or

Company with the Trustee), as follows: Paine Webber Group Inc., 1285 Avenue of
the Americas, New York, New York 10019, Attention of Secretary. Any notice,
election, request or demand by the Company or any Debentureholder to or upon the
Trustee shall be deemed to have been sufficiently given or made, for all
purposes, if given or made in writing at the Corporate Trust Office of the
Trustee.

                  SECTION 13.05. This Indenture and each Debenture shall be
deemed to be a contract made under the laws of the State of New York, and for
all purposes shall be construed in accordance with the laws of said State
(without regard to principles of conflicts of laws thereof).

                  SECTION 13.06. (a) Upon any application or demand by the
Company to the Trustee to take any action under any of the provisions of this
Indenture, the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent provided for in this Indenture relating to

that in the opinion of such counsel all such conditions precedent have been
complied with, except that in the case of any such application or demand as to
which the furnishing of such documents is specifically required by any provision
of this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

                  (b) Each certificate or opinion provided for in this Indenture
and delivered to the Trustee with respect to compliance with a condition or
covenant in this Indenture (other than the Certificate provided pursuant to
Section 5.03(d)) shall include (1) a statement that the person making such

                                                                            75

interest or principal of any Debenture or the date of redemption of any
Debenture shall not be a Business Day then payment of interest or principal (and
premium, if any) may be made on the next succeeding day which is a Business Day
with the same force and effect as if made on the nominal date of maturity or
redemption, and no interest shall accrue for the period after such nominal date.

                  SECTION 13.08. If and to the extent that any provision of this
Indenture limits, qualifies or conflicts with the duties imposed by Sections 310
to 317, inclusive, of the Trust Indenture Act, such imposed duties shall
control.

                  SECTION 13.09. This Indenture may be executed in any number of
counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

                  SECTION 13.10. In case any one or more of the provisions
contained in this Indenture or in the Debentures of any series shall for any
reason be held to be invalid, illegal or unenforceable in any respect, such
invalidity, illegality or unenforceability shall not affect any other provisions
of this Indenture or of such Debentures, but this Indenture and such Debentures
shall be construed as if such invalid or illegal or unenforceable provision had
never been contained herein or therein.

                  SECTION 13.11. The Company will have the right at all times to
assign any of its rights or obligations under this Indenture to a direct or
indirect wholly owned Subsidiary of the Company; provided that, in the event of
any such assignment, the Company will remain jointly and severally liable for
all such obligations. Subject to the foregoing, this Indenture is binding upon
and inures to the benefit of the parties thereto and their respective successors
and assigns. This Indenture may not otherwise be assigned by the parties hereto.

                  SECTION 13.12. The Company hereby acknowledges that, to the
extent specifically set forth herein, prior to a Security Exchange with respect
to the Debentures of any series held as trust assets of a PWG Capital Trust, the
holders of the Preferred Securities of such PWG Capital Trust shall expressly be
third party beneficiaries of this Indenture. The Company further acknowledges
that, prior to a Security Exchange with respect to Debentures of any series
<PAGE>   89
                                                                            76

held as trust assets of a PWG Capital Trust, if the Property Trustee of such PWG
Capital Trust fails to enforce its rights under this Indenture as the holder of
the Debentures of a series held as trust assets of such PWG Capital Trust, any
holder of the Preferred Securities of such PWG Capital Trust may institute legal
proceedings directly against the Company to enforce such Property Trustee's
rights under this Indenture without first instituting any legal proceedings
against such Property Trustee or any other Person.


                                   ARTICLE XIV

                           Subordination of Debentures

                  SECTION 14.01. The Company, for itself, its successors and
assigns, covenants and agrees, and each holder of a Debenture, by its acceptance
thereof, likewise covenants and agrees, that the payment of the principal of
(premium, if any), and interest on, each and all of the Debentures is hereby
expressly subordinated, to the extent and in the manner hereinafter in this
Article set forth, in right of payment to the prior payment in full of all
Senior Indebtedness. The provisions of this Article are made for the benefit of
all holders of Senior Indebtedness, and any such holder may proceed to enforce
such provisions.

                  SECTION 14.02. No payment by the Company on account of
principal of (premium, if any), or interest on, the Debentures of any series
shall be made if any default or event of default with respect to any Senior
Indebtedness, which permits or with the giving of notice or passage of time or
both would permit the holders thereof (or a trustee on their behalf) to
accelerate the maturity thereof, shall have occurred and be continuing and the
Company and the Trustee shall have received written notice thereof from the
holders of at least 10% in principal amount of any kind or category of any
Senior Indebtedness (or the representative or trustee of such holders) or the
Trustee shall have received written notice thereof from the Company.

                  In the event that any Debentures of any series are declared
due and payable before the date specified therein as the fixed dated on which
the principal thereof is due and payable pursuant to Article VI, or upon any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution or
winding up or total or
<PAGE>   90
                                                                            77

partial liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
principal of (premium, if any) and interest due or to become due upon all Senior
Indebtedness shall first be paid in full before any holders of Debentures, or
the Trustee, shall be entitled to receive or retain any assets (other than
shares of stock of the Company as reorganized or readjusted or securities of the
Company or any other corporation provided for by a plan of reorganization or
readjustment, the payment of which is subordinated, at least to the same extent
as the Debentures, to the payment of all Senior Indebtedness which may at the
time be outstanding, provided that the rights of the holders of the Senior
Indebtedness are not altered by such reorganization or readjustment) so paid or
distributed in respect of the Debentures (for principal or interest); and upon
such dissolution or winding up or liquidation or reorganization, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (other than shares of stock of the Company as reorganized
or readjusted or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the same extent as the Debentures, to the payment of
all Senior Indebtedness which may at the time be outstanding, provided that the
rights of the holders of the Senior Indebtedness are not altered by such
reorganization or readjustment), to which any holder of Debentures or the
Trustee would be entitled, except for the provisions of this Section, shall be
paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other person making such payment or distribution, or by any
holder of Debentures or the Trustee if received by them or it, directly to the
holders of Senior Indebtedness (pro rata to each such holder on the basis of the
respective amounts of Senior Indebtedness held by such holder) or their
representatives or trustees, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness, before any payment or
distribution is made to the holders of Debentures or to the Trustee.

                  No holder of Senior Indebtedness shall be prejudiced in his
right to enforce subordination of the Debentures of any series by any act or
failure to act on the part of the Company.
<PAGE>   91
                                                                            78

                  Without notice to or the consent of any holder of Debentures
or the Trustee the holders of Senior Indebtedness may at any time and from time
to time, without impairing or releasing the subordination herein made, change
the manner, place or terms of payment, or change or extend the time of payment
of or renew or alter the Senior Indebtedness, or amend or supplement in any
manner any instrument evidencing the Senior Indebtedness, any agreement pursuant
to which the Senior Indebtedness was issued or incurred or any instrument
securing or relating to the Senior Indebtedness; release any person liable in
any manner for the payment or collection of the Senior Indebtedness; exercise or
refrain from exercising any rights in respect of the Senior Indebtedness against
the Company or any other person; apply any moneys or other property paid by any
person or released in any manner to the Senior Indebtedness; or accept or
release any security for the Senior Indebtedness.

                  Subject to the payment in full of all Senior Indebtedness, the
holders of Debentures shall be subrogated (equally and ratably with the holders
of all indebtedness of the Company that, by its express terms, ranks on a parity
with the Debentures and is entitled to like rights or subrogation) to the rights
of the holders of Senior Indebtedness to receive payments or distributions of
assets of the Company applicable to the Senior Indebtedness until the Debentures
shall be paid in full. For purposes of such subrogation, no payments or
distributions on the Senior Indebtedness pursuant to this Section shall, as
between the Company, its creditors other than the holders of Senior
Indebtedness, and the holders of the Debentures, be deemed to be a payment by
the Company to or on account of the Senior Indebtedness, and no payments or
distributions to the Trustee or the holders of the Debentures of assets by
virtue of the subrogation herein provided for shall, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the
Debentures, be deemed to be a payment to or on account of the Debentures. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the holders of the Debentures, on the one hand,
and the holders of Senior Indebtedness, on the other hand, and nothing contained
in this Article or elsewhere in this Indenture or in the Debentures of any
series is intended to or shall impair the obligation of the Company, which is
unconditional and absolute, to pay the principal of and interest on the
Debentures of any series when the same shall become due and payable in
accordance with their terms, or to affect the
<PAGE>   92
                                                                            79

relative rights of the holders of the Debentures and creditors of the Company
other than the holders of Senior Indebtedness, nor shall anything herein or
therein prevent the Trustee or the holder of any Debenture from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article, of the holders of
Senior Indebtedness in respect of cash, property or securities of the Company
otherwise payable or delivered to the Trustee or any holder of Debentures upon
the exercise of any such remedy.

                  Upon any payment or distribution pursuant to this Section, the
Trustee and any holder of Debentures shall be entitled to rely upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in this Section are pending, and the Trustee, subject to the
provisions of Section 7.01, and any holder of Debentures shall be entitled to
rely upon a certificate of the liquidating trustee or agent or other person
making such payment or distribution delivered to the Trustee or to any holder of
Debentures, for the purpose of ascertaining the persons entitled to participate
in such payment or distribution, the holders of the Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Section. In the event that the Trustee determines, in good
faith, that evidence is required with respect to the right of any person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Section, the Trustee may request such person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, as to the extent to which such person
is entitled to participate in such payment or distribution, and as to other
facts pertinent to the rights of such person under this Section, and if such
evidence is not furnished, the Trustee may defer any payment to such person
pending judicial determination as to the right of such person to receive such
payment.

                  Nothing contained in this Article or elsewhere in this
Indenture, or in any of the Debentures of any series, shall prevent (a) the
application by the Trustee or any paying agent of any moneys deposited with it
hereunder to the payment of or on account of the principal of or interest on
Debentures of any series if, at the time of such deposit (provided that the time
of such deposit was not more than 10
<PAGE>   93
                                                                            80

days prior to the time of such payment), such payment would not have been
prohibited by the foregoing provisions of this Section or (b) any payment by the
Company or the Trustee to any holder of Debentures of moneys in connection with
a redemption of Debentures of any series if (i) notice of such redemption has
been given to the holders of the Debentures to be redeemed pursuant to Article
III prior to the receipt by the Trustee of the written notice referred to in
Section 14.04 and (ii) such notice of redemption is given not earlier than 60
days before the date fixed for redemption.

                  SECTION 14.03. The holder of each Debenture by his acceptance
thereof authorizes and directs the Trustee on his behalf to take such action as
may be necessary or appropriate to acknowledge and effectuate the subordination
between the holders of Debentures and the holders of Senior Indebtedness as
provided in this Article and appoints the Trustee as attorney-in-fact for any
and all such purposes.

                  SECTION 14.04. Notwithstanding the provisions of this Article
or any other provision of this Indenture, but subject to the provisions of
Section 7.01, the Trustee and any paying agent shall not be charged with
knowledge of the existence of any Senior Indebtedness, or any default in the
payment of the principal of (premium, if any), or interest on, any Senior
Indebtedness, or of any facts which would prohibit the making of any payment of
moneys to or by the Trustee or any such paying agent, unless and until the
Trustee or such paying agent shall have received written notice thereof from the
Company or the holders of at least 10% in principal amount of any kind or
category of any Senior Indebtedness or the representative or trustee of such
holders; nor shall the Trustee or any such paying agent be charged with
knowledge of the curing of any such default or of the elimination of the act or
condition preventing any such payment unless and until the Trustee or such
paying agent shall have received an Officers' Certificate to such effect.

                  SECTION 14.05. The Trustee shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness which may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness; and nothing in Section 7.13, or elsewhere in this Indenture, shall
deprive the Trustee of any of its rights as such holder. Nothing in this Article
shall apply to claims of,
<PAGE>   94
                                                                            81

or payments to, the Trustee under or pursuant to Section 7.06.

                  SECTION 14.06. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness and shall not be liable to
any such holders if it shall mistakenly pay over or distribute to any holder of
Debentures or the Company or any other person moneys or assets to which any
holders of Senior Indebtedness shall be entitled by virtue of this Article or
otherwise.

                  SECTION 14.07. In case at any time any paying agent other than
the Trustee shall have been appointed by the Company and be acting hereunder,
the term "Trustee" as used in this Article shall in such case (unless the
context shall otherwise require) be construed as extending to and including such
paying agent within its meaning as fully for all intents and purposes as if such
paying agent were named in this Article in addition to or in place of the
Trustee; provided, however, that Sections 14.04, 14.05 and 14.06 shall not apply
to the Company if it acts as paying agent.

                  The Chase Manhattan Bank, as Trustee, hereby accepts the trust
in this Indenture declared and provided, upon the terms and conditions
hereinabove set forth.


                  IN WITNESS WHEREOF, the parties hereto have caused this
Indenture to be duly executed, and their respective corporate seals to be
hereunto affixed and attested, all as of the day and year first above written.

Securities have been cured or waived by the Holders of Preferred Securities as
provided in this Declaration or otherwise eliminated and until all Events of
Default with respect to the Preferred Securities have been so cured, waived or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of the Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Property Trustee in
accordance with the terms of this Declaration or the Securities. In the event
that an Event of Default with respect to the Preferred Securities is waived by
the Holders of Preferred Securities as provided in this Declaration, the Holders
of Common Securities agree that such waiver shall also constitute the waiver of
such Event of Default with respect to the Common Securities for all purposes
under this Declaration without any further act, vote or consent of the Holders
of the Common Securities. Subject to the foregoing provisions of this Section 
2.06(b), upon such waiver, any such default shall cease to exist and any Event
of Default with respect to the Common Securities arising therefrom shall be
deemed to have been cured for every purpose of this Declaration, but no such
waiver shall extend to any subsequent or other default or Event of Default with
respect to the Common Securities or impair any right consequent thereon.

                  (c) The right of any Holder of Securities to receive payment
of Distributions on the Securities in accordance with this Declaration and the
terms of the Securities set forth in Exhibits B and C on or after the

any such payment on or after such payment dates, shall not be impaired without
the consent of such Holder.

                  (d) As provided in the terms of the Securities set forth in
Exhibits B and C hereto, a waiver of an Indenture Event of Default by the
Property Trustee at the written direction of the Holders of the Preferred
Securities constitutes a waiver of the corresponding Event of Default under this
Declaration in respect of the Securities.

                  SECTION 2.07. Disclosure of Information. The disclosure of
information as to the names and addresses of the Holders of the Securities in
accordance with Section 312 of the Trust Indenture Act, regardless of the source
from which such information was derived, shall not be deemed to be a violation
of any existing law or any law hereafter enacted which does not specifically
refer to Section 312 of the Trust Indenture Act, nor shall the Property Trustee
be held accountable by reason of mailing any material pursuant to a request made
under Section 312(b) of the Trust Indenture Act.

                  (g) The Property Trustee shall, within 90 days after the
occurrence of a default with respect to the Securities, transmit by mail, first
class postage prepaid, to the holders of the Securities, as their names and
addresses appear upon the register, notice of all defaults with respect to the
Securities known to the Property Trustee, unless such defaults shall have been
cured before the giving of such notice (the term "defaults" for the purposes of
this Section 3.10(g) being hereby defined to be an Indenture Event of Default,
not including any periods of grace provided for in the Indenture and
irrespective of the giving of any notice provided therein); provided that,
except in the case of default in the payment of the principal of (or premium, if
any) or interest on any of the Debentures, the Property Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Property Trustee in good faith determines that the withholding
of such notice is in the interests of the Holders of the Securities. The
Property Trustee shall not be deemed to

have knowledge of any default, except (i) a default in the payment of principal
of (or premium, if any) or interest on the Debentures or (ii) any default as to
which the Property Trustee shall have received written notice or a Responsible
Officer charged with the administration of this Declaration shall have obtained
written notice.

                  (h)  The Property Trustee shall not resign as a Trustee unless
either:

                  (i) the Trust has been completely liquidated and
         the proceeds thereof distributed to the Holders of
         Securities pursuant to the terms of the Securities; or

                (ii) a Successor Property Trustee has been appointed and
         accepted that appointment in accordance with Article V.

                  (i) The Property Trustee shall act as paying agent in respect

3.08(r), may authorize one or more Persons (each, a "Paying Agent") to pay
Distributions, redemption payments or liquidation payments on behalf of the
Trust with respect to the Preferred Securities. Any such Paying Agent shall
comply with Section 317(b) of the Trust Indenture Act. Any Paying Agent may be
removed by the Property Trustee, after consultation with the Regular Trustees,
at any time and a successor Paying Agent or additional Paying Agents may be
appointed at any time by the Property Trustee, subject to Section 3.08(r).

                  (j) The Property Trustee shall give prompt written notice to
the Holders of the Securities of any notice received by it from PWG of its
election to defer payments of interest on the Debentures by extending the
interest payment period with respect thereto.

                  (k) Subject to this Section 3.10, the Property Trustee shall

rights set forth in this Section 3.10 and Section 3.12 in a manner which is
consistent with the purposes and functions of the Trust set out in Section 3.05,
and the Property Trustee shall not take any action which is inconsistent with
the purposes and functions of the Trust set forth in Section 3.05.

                  SECTION 3.11. Delaware Trustee. Notwithstanding any other
provision of this Declaration other than Section 5.01(a)(3), the Delaware
Trustee shall not be entitled to exercise any powers, nor shall the Delaware
Trustee have any of the duties and responsibilities of the Regular Trustees or
the Property Trustee described in this Declaration. Except as set forth in
Section 5.01(a)(3), the Delaware Trustee shall be a Trustee for the sole and
limited purpose of fulfilling the requirements of Section 3807 of the Business
Trust Act. No implied covenants or obligations shall be read into this
Declaration against the Delaware Trustee.

                  SECTION 3.12. Certain Rights and Duties of the Property
Trustee. (a) The Property Trustee, before the occurrence of an Event of Default
and after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Declaration, and no implied covenants shall be read into this Declaration
against the Property Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.06), the Property Trustee shall
exercise such of the rights and powers vested in it by this Declaration, and use
the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

                  (b) No provision of this Declaration shall be construed to
relieve the Property Trustee from liability for its own negligent action, its
own negligent failure to act or its own willful misconduct, except that:

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

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

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

                (ii) the Property Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer of the Property
         Trustee, unless it shall be proved that the Property Trustee was
         negligent in ascertaining the pertinent facts;

              (iii) the Property Trustee shall not be liable with respect to any
         action taken or omitted to be taken by it in good faith in accordance
         with the direction of the Holders as provided herein relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Property Trustee hereunder or under the Indenture, or
         exercising any trust or power conferred upon the Property Trustee under
         this Declaration; and

                (iv) no provision of this Declaration shall require the Property
         Trustee to expend or risk its own funds or otherwise incur personal
         financial liability in the performance of any of its duties or in the
         exercise of any of its rights or powers, if it shall have reasonable
         ground for believing that the repayment of such funds or liability is
         not reasonably assured to it under the terms of this Declaration or
         adequate indemnity against such risk or liability is not reasonably
         assured to it.

                  (c)  Subject to the provisions of Section 3.12(a)
and (b):

                  (i) whenever in the administration of this Declaration, the
         Property Trustee shall deem it desirable that a matter be proved or
         established prior

         to taking, suffering or omitting any action hereunder, the Property
         Trustee (unless other evidence is herein specifically prescribed) may,
         in the absence of bad faith on its part and, if the Trust is excluded
         from the definition of Investment Company solely by means of Rule 3a-7,
         subject to the requirements of Rule 3a-7, request and rely upon a
         certificate, which shall comply with the provisions of Section 314(e)
         of the Trust Indenture Act, signed by any two of the Regular Trustees
         or by an authorized officer of the Sponsor, as the case may be;

                (ii) the Property Trustee (A) may consult with counsel (which
         may be counsel to the Sponsor or any of its Affiliates and may include
         any of its employees) selected by it in good faith and with due care
         and the written advice or opinion of such counsel with respect to legal
         matters shall be full and complete authorization and protection in
         respect of any action taken, suffered or omitted by it hereunder in
         good faith and in reliance thereon and in accordance with such advice
         and opinion and (B) shall have the right at any time to seek
         instructions concerning the administration of this Declaration from any
         court of competent jurisdiction;

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

                (iv) the Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Declaration
         at the request or direction of any Holders, unless such Holders shall
         have offered to the Property Trustee reasonable security and indemnity
         against the costs, expenses (including attorneys' fees and expenses)
         and liabilities that might be incurred by it in complying with such
         request or direction; provided that nothing contained in this clause
         (iv) shall relieve the Property Trustee of the obligation, upon the
         occurrence of an Event of Default (which has not been cured or waived)
         to exercise such of the rights and powers vested in it by this
         Declaration, and to use the same degree of care and skill in this
         exercise, as a prudent

         person would exercise or use under the circumstances in the conduct of 
         his or her own affairs;

                  (v) any action taken by the Property Trustee or its agents
         hereunder shall bind the Trust and the Holders of the Securities and
         the signature of the Property Trustee or its agents alone shall be
         sufficient and effective to perform any such action; and no third party
         shall be required to inquire as to the authority of the Property
         Trustee to so act, or as to its compliance with any of the terms and
         provisions of this Declaration, both of which shall be conclusively
         evidenced by the Property Trustee's or its agent's taking such action;

                (vi) the Property Trustee may rely and shall be fully protected
         in acting or refraining from acting upon any resolution, certificate,
         statement, instrument, opinion, report, notice, request, consent,
         order, approval, bond, security or other paper or document believed by
         it to be genuine and to have been signed, sent or presented by the
         proper party or parties; and

              (vii) the Property Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,

         Property Trustee, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit.

                  SECTION 4.01. Purchase of Common Securities by Sponsor. On the
Closing Date, the Sponsor will purchase all of the Common Securities issued by
the Trust at the same time as the Preferred Securities to be issued on such date
are issued, such purchase to be in an amount equal to 3% of the total capital of
the Trust. On the Option Closing Date, the Sponsor shall purchase all of the
Common Securities issued by the Trust at the same time as the Preferred
Securities to be issued on such date are issued, such purchase to be in such
amount so that the Common Securities continue to represent 3% of the total
capital of the Trust.

                  SECTION 4.02. Expenses. (a) In connection with the purchase of
the Debentures by the Trust, the Sponsor, in its capacity as Sponsor and not as
a Holder, shall be responsible for and shall pay for all debts and obligations

Trust (including, but not limited to, costs and expenses relating to the
organization of the Trust, the issuance of the Preferred Securities to initial
purchasers thereof, the fees and expenses (including reasonable counsel fees and

Trust, the Sponsor, in its capacity as Sponsor and not as a Holder, will pay any
and all taxes (other than United States withholding taxes attributable to the
Trust or its assets) and all liabilities, costs and expenses with respect to
such taxes of the Trust.

                  (c) The Sponsor's obligations under this Section 4.02 shall be
for the benefit of, and shall be enforceable by, any Person to whom any such
debts, obligations, costs, expenses and taxes are owed (a "Creditor") whether or
not such Creditor has received notice

hereof. Any such Creditor may enforce the Sponsor's obligations under this
Section 4.02 directly against the Sponsor and the Sponsor irrevocably waives any
right or remedy to require that any such Creditor take any action against the
Trust or any other Person before proceeding against the Sponsor. The Sponsor
agrees to execute such additional agreements as may be necessary or desirable in
order to give full effect to the provisions of this Section 4.02.

         or of the District of Columbia, or a corporation or Person permitted by
         the Commission to act as an institutional trustee under the Trust
         Indenture Act, authorized under such laws to exercise corporate trust
         powers, having a combined capital and surplus of at least $50,000,000,
         and subject to supervision or examination by Federal, State,
         Territorial or District of Columbia authority. If such corporation
         publishes reports of condition at least annually, pursuant to law or to
         the requirements of the supervising or examining authority referred to
         above, then for the purposes of this Section 5.01(c)(ii), the combined
         capital and surplus of such corporation shall be deemed to be its
         combined capital and surplus as set forth in its most recent report of
         condition so published; and

              (iii) if the Trust is excluded from the definition of an 
         Investment Company solely by reason of Rule 3a-7

         and to the extent Rule 3a-7 requires a trustee having certain
         qualifications to hold title to the "eligible assets" (as defined in
         Rule 3a-7) of the Trust, the Property Trustee shall possess those
         qualifications.

                  If at any time the Property Trustee shall cease to satisfy the
requirements of clauses (i)-(iii) above, the Property Trustee shall immediately
resign in the manner and with the effect set out in Section 5.02(d). If the
Property Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Property Trustee and
the Holders of the Common Securities (as if such Holders were the obligor
referred to in Section 310(b) of the Trust Indenture Act) shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act. The
Preferred Guarantee shall be deemed to be specifically described in this
Declaration for the purposes of clause (i) of the first proviso contained in
Section 310(b) of the Trust Indenture Act.

                  The initial Trustee which shall serve as the Property Trustee

                  (d) The initial Trustee which shall serve as the Delaware
Trustee is Chase Manhattan Bank Delaware, a Delaware banking corporation, whose
address is as set forth
in Section 14.01(c).

                  (e) Any action taken by Holders of Common Securities pursuant

convened for such purpose or by written consent as provided in Section 12.02.

change any rights with respect to the number, existence or appointment and
removal of Trustees, except with the consent of each Holder of Common
Securities.

                                                                              34










                (ii) after the issuance of the Securities by vote of the Holders
         of a Majority in liquidation amount of the Common Securities voting as
         a class.

                  (b)(i) The Trustee that acts as Property Trustee shall not be
         removed in accordance with Section 5.02(a) until a Successor Property
         Trustee possessing the qualifications to act as Property Trustee under
         Section 5.01(c) has been appointed and has accepted such appointment by
         written instrument executed by such Successor Property Trustee and
         delivered to the Regular Trustees, the Sponsor and the Property Trustee
         being removed; and

                (ii) the Trustee that acts as Delaware Trustee shall not be
         removed in accordance with Section 5.02(a) until a successor Trustee
         possessing the qualifications to act as Delaware Trustee under Section 
         5.01(a)(3) (a "Successor Delaware Trustee") has been appointed and has
         accepted such appointment by written instrument executed by such
         Successor Delaware Trustee and delivered to the Regular Trustees, the
         Sponsor and the Delaware Trustee being removed.

                  (c) A Trustee appointed to office shall hold office until his
         successor shall have been appointed or until his death, removal or
         resignation.

                  (d) Any Trustee may resign from office (without need for prior
         or subsequent accounting) by an instrument (a "Resignation Request") in
         writing signed by the Trustee and delivered to the Sponsor and the
         Trust, which resignation shall take effect upon such delivery or upon
         such later date as is specified therein; provided, however, that:

                  (i) no such resignation of the Trustee that acts as the
         Property Trustee shall be effective until:

                           (A) a Successor Property Trustee possessing the
                  qualifications to act as Property Trustee under Section 
                  5.01(c) has been appointed and has accepted such appointment
                  by instrument executed by such Successor Property Trustee and
                  delivered to the Trust, the Sponsor and the resigning Property
                  Trustee; or

                                                                              35










                           (B) if the Trust is excluded from the definition of
                  an Investment Company solely by reason of Rule 3a-7, until the
                  assets of the Trust have been completely liquidated and the
                  proceeds thereof distributed to the Holders of the Securities;
                  and

                (ii) no such resignation of the Trustee that acts as the
         Delaware Trustee shall be effective until a Successor Delaware Trustee
         has been appointed and has accepted such appointment by instrument
         executed by such Successor Delaware Trustee and delivered to the Trust,
         the Sponsor and the resigning Delaware Trustee.

                  (e) If no Successor Property Trustee or Successor Delaware
         Trustee shall have been appointed and accepted appointment as provided
         in this Section 5.02 within 60 days after delivery to the Sponsor and
         the Trust of a Resignation Request, the resigning Property Trustee or
         Delaware Trustee may petition any court of competent jurisdiction for
         appointment of a Successor Property Trustee or Successor Delaware
         Trustee. Such court may thereupon after such notice, if any, as it may
         deem proper and prescribe, appoint a Successor Property Trustee or
         Successor Delaware Trustee, as the case may be.

                  (f) The Sponsor shall provide notice to the Property Trustee
         of any resignation or removal of a Regular Trustee.

                  SECTION 5.03. Vacancies Among Trustees. If a Trustee ceases to
hold office for any reason and the number of Trustees is not reduced pursuant to
Section 5.01 or if the number of Trustees is increased pursuant to Section 5.01,
a vacancy shall occur. A resolution certifying the existence of such vacancy by
a majority of the Regular Trustees shall be conclusive evidence of the existence
of such vacancy. The vacancy shall be filled with a Trustee appointed in
accordance with the requirements of this Article V.

                  SECTION 5.04. Effect of Vacancies. The death, resignation,
retirement, removal, bankruptcy, dissolution, liquidation, incompetence or
incapacity to perform the duties of a Trustee, or any one of them, shall not
operate to annul the Trust. Whenever a vacancy in the number of Regular Trustees
shall occur until such vacancy is filled as

                                                                              36










provided in this Article V, the Regular Trustees in office, regardless of their
number, shall have all the powers granted to the Regular Trustees and shall
discharge all the duties imposed upon the Regular Trustees by this Declaration.

                  SECTION 5.05. Meetings. Meetings of the Regular Trustees shall
be held from time to time upon the call of any Trustee. Regular meetings of the
Regular Trustees may be held at a time and place fixed by resolution of the
Regular Trustees. Notice of any in-person meeting of the Regular Trustees shall
be hand delivered or otherwise delivered in writing (including by facsimile,
with a hard copy by overnight courier) not less than 48 hours before such
meeting. Notice of any telephonic meeting of the Regular Trustees or any
committee thereof shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 24
hours before such meeting. Notices shall contain a brief statement of the time,
place and anticipated purposes of the meeting. The presence (whether in person
or by telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened. Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter;
provided that a Quorum is present, or without a meeting by the unanimous written
consent of the Regular Trustees.

                  SECTION 5.06. Delegation of Power. (a) Any Regular Trustee
may, by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing
any registration statement or amendment thereto or other document or schedule
filed with the Commission or making any other governmental filing (including,
without limitation the filings referred to in Section 3.13).

                  (b) The Regular Trustees shall have the power to delegate from
time to time to such of their number or to officers of the Trust or to officers
of Paine Webber Group or Paine Webber Incorporated the doing of such things and
the execution of such instruments either in the name of the

Trust or the names of the Regular Trustees or otherwise as the Regular Trustees
may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.


                                   ARTICLE VI

                                  Distributions

                  SECTION 6.01. Distributions. Holders shall receive periodic
distributions, redemption payments and liquidation distributions in accordance
with the applicable terms of the relevant Holder's Securities ("Distributions").
Distributions shall be made to the Holders of Preferred Securities and Common
Securities in accordance with the terms of the Securities as set forth in
Exhibits B and C hereto. If and to the extent that PWG makes a payment of
interest (including Compounded Interest (as defined in the Indenture)), premium
or principal on the Debentures held by the Property Trustee (the amount of any
such payment being a "Payment Amount"), the Property Trustee shall and is
directed to promptly make a Distribution of the Payment Amount to Holders in
accordance with the terms of the Securities as set forth in Exhibits B and C
hereto.


                                   ARTICLE VII

                             Issuance of Securities

                  SECTION 7.01. General Provisions Regarding Securities. (a) The
Regular Trustees shall issue on behalf of the Trust securities in fully
registered form representing undivided beneficial interests in the assets of the
Trust in accordance with Section 7.01(b) and for the consideration specified in
Section 3.03.

                  (b) The Regular Trustees shall issue on behalf of the Trust
one class of preferred securities representing undivided beneficial interests in
the assets of the Trust having such terms as are set forth in Exhibit B (the
"Preferred Securities") which terms are incorporated by reference in, and made a
part of, this Declaration as if specifically set forth herein, and one class of
common securities representing undivided beneficial interests in the assets of
the Trust having such terms as are set forth in Exhibit C (the "Common
Securities") which terms are





    
<PAGE>   45
                                                                              38










incorporated by reference in, and made a part of, this Declaration as if
specifically set forth herein. The Trust shall have no securities or other
interests in the assets of the Trust other than the Preferred Securities and the
Common Securities.

                  (c) The Certificates shall be signed on behalf of the Trust by
the Regular Trustees (or if there are more than two Regular Trustees by any two
of the Regular Trustees). Such signatures may be the manual or facsimile
signatures of the present or any future Regular Trustee. Typographical and other
minor errors or defects in any such reproduction of any such signature shall not
affect the validity of any Certificate. In case any Regular Trustee of the Trust
who shall have signed any of the Certificates shall cease to be such Regular
Trustee before the Certificate so signed shall be delivered by the Trust, such
Certificate nevertheless may be delivered as though the person who signed such
Certificate had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons as, at the actual date of the
execution of such Certificate, shall be the Regular Trustees of the Trust,
although at the date of the execution and delivery of the Declaration any such
person was not such a Regular Trustee. Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange on which
the Securities may be listed, or to conform to usage. Pending the preparation of
definitive Certificates, the Regular Trustees on behalf of the Trust may execute
temporary Certificates (printed, lithographed or typewritten), in substantially
the form of the definitive Certificates in lieu of which they are issued, but
with such omissions, insertions and variations as may be appropriate for
temporary Certificates, all as may be determined by the Regular Trustees. Each
temporary Certificate shall be executed by the Regular Trustees on behalf of the
Trust upon the same conditions and in substantially the same manner, and with
like effect, as definitive Certificates. Without unnecessary delay, the Regular
Trustees on behalf of the Trust will execute and furnish definitive Certificates
and thereupon any or all temporary Certificates may be

                                                                              39










surrendered to the transfer agent and registrar in exchange therefor (without
charge to the Holders). Each Certificate whether in temporary or definitive form
shall be countersigned by the manual or facsimile signature of an authorized
signatory of the Person acting as registrar and transfer agent for the
Securities, which shall initially be the Property Trustee.

                  (d) The consideration received by the Trust for the issuance
of the Securities shall constitute a contribution to the capital of the Trust
and shall not constitute a loan to the Trust.

                  (e) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

                  (f) Every Person, by virtue of having become a Holder or a
Preferred Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

                  (g) Upon issuance of the Securities as provided in this
Declaration, the Regular Trustees on behalf of the Trust shall return to PWG the
$10 constituting initial trust assets as set forth in the Original Declaration.

                              Termination of Trust

                  SECTION 8.01.  Termination of Trust.  The Trust shall 
dissolve when:

                  (i) all of the Securities shall have been called for
         redemption and the amounts necessary for redemption thereof shall have
         been paid to the Holders of Securities in accordance with the terms of
         the Securities; or

                (ii) all of the Debentures shall have been distributed to the
         Holders of Securities in exchange for all of the Securities in
         accordance with the terms of the Securities; or

                                                                              40










                  (iii) upon the expiration of the term of the Trust as set
         forth in Section 3.17,

and thereafter the Trustees shall, after satisfaction of all obligations of the
Trust, file a certificate of cancelation with the Secretary of State of the
State of Delaware and the Trust shall terminate. The Trustees shall so file such
a certificate as soon as practicable after the occurrence of an event referred
to in this Section 8.01.

                  The provisions of Sections 3.12 and 4.02 and Article X shall
survive the termination of the Trust.


                                   ARTICLE IX

                              Transfer of Interests

                  SECTION 9.01. Transfer of Securities. (a) Securities may only
be transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

                  (b)  Subject to this Article IX, Preferred
Securities shall be freely transferable.

                  (c) Subject to this Article IX, PWG and any Related Party may
only transfer Common Securities to PWG or a Related Party; provided that any
such transfer shall be subject to the condition that the transferor shall have
obtained (1) either a ruling from the Internal Revenue Service or an unqualified
written opinion addressed to the Trust and delivered to the Trustees of
nationally recognized independent tax counsel experienced in such matters to the
effect that such transfer will not (i) cause the Trust to be treated as issuing
a class of interests in the Trust differing from the class of interests
represented by the Common Securities originally issued to PWG, (ii) result in
the Trust acquiring or disposing of, or being deemed to have acquired or
disposed of, an asset, or (iii) result in or cause the Trust to be treated as
anything other than a grantor trust for United States Federal income tax
purposes and (2) an unqualified written opinion addressed to the Trust and
delivered to the Trustees of a nationally recognized independent counsel
experienced in such matters





    
<PAGE>   48
                                                                              41










that such transfer will not cause the Trust to be an Investment Company or
controlled by an Investment Company.

                  SECTION 9.02. Transfer of Certificates. The Regular Trustees
shall cause to be kept at an office or agency to be maintained by the Trust a
register in which, subject to such reasonable regulations as it may prescribe,
the Trust shall provide for the registration of Certificates and of transfers of
Certificates, which will be effected without charge but only upon payment (with
such indemnity as the Trust may require) in respect of any tax or other
government charges which may be imposed in relation to it. The Property Trustee
will be the initial registrar and transfer agent (the "Registrar") for the
purpose of registering Certificates and transfers of Certificates as provided
herein.

                  Upon surrender for registration of transfer of any Certificate
at the office or agency of the Registrar, the Regular Trustees shall execute and
the Registrar shall countersign in accordance with section 7.01(c) one or more
new Certificates of any authorized denominations and of a like aggregate
liquidation amount to be issued in the name of the designated transferee or
transferees. Every Certificate surrendered for registration of transfer shall be
accompanied by a written instrument of transfer in form satisfactory to the
Trust duly executed by the Holder or such Holder's attorney duly authorized in
writing. Each Certificate surrendered for registration of transfer shall be
canceled by the Regular Trustees. A transferee of a Certificate shall be
entitled to the rights and subject to the obligations of a Holder hereunder upon
the receipt by such transferee of a Certificate. By acceptance of a Certificate,
each transferee shall be deemed to have agreed to be bound by this Declaration.

                  SECTION 9.03. Deemed Security Holders. The Trustees may treat
the Person in whose name any Certificate shall be registered on the books and
records of the Trust as the sole holder of such Certificate and of the
Securities represented by such Certificate for purposes of receiving
Distributions and for all other purposes whatsoever and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such
Certificate or in the Securities represented by such Certificate on the part of
any Person, whether or not the Trustees shall have actual or other notice
thereof.

                  SECTION 9.04. Book Entry Interests. Unless otherwise specified
in the terms of the Preferred Securities, the Preferred Securities Certificates,
on original issuance (including Preferred Securities, if any, issued on the
Option Closing Date pursuant to the exercise of the overallotment option set
forth in the Underwriting Agreement), will be issued in the form of one or more,
fully registered, global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Trust. Such Global Certificates shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of
DTC, and no Preferred Security Beneficial Owner will receive a definitive
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certificates, except as provided in Section 
9.07. Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been issued
to the Preferred Security Beneficial Owners pursuant to Section 9.07:

                  (i) the provisions of this Section 9.04 shall be
         in full force and effect;

                (ii) the Trust and the Trustees shall be entitled to deal with
         the Clearing Agency for all purposes of this Declaration (including the
         payment of Distributions on the Global Certificates and receiving
         approvals, votes or consents hereunder) as the Holder of the Preferred
         Securities and the sole holder of the Global Certificates and shall
         have no obligation to the Preferred Security Beneficial Owners;

              (iii) to the extent that the provisions of this Section 9.04
         conflict with any other provisions of this Declaration, the provisions
         of this Section 9.04 shall control; and

                (iv) the rights of the Preferred Security Beneficial Owners
         shall be exercised only through the Clearing Agency and shall be
         limited to those established by law and agreements between such
         Preferred Security Beneficial Owners and the Clearing Agency and/or the
         Clearing Agency Participants. DTC will make book entry transfers among
         the Clearing Agency Participants and receive and transmit payments

         of Distributions on the Global Certificates to such Clearing Agency
         Participants.

                  SECTION 9.05. Notices to Holders of Certificates. Whenever a
notice or other communication to the Holders is required to be given under this
Declaration, unless and until Definitive Preferred Security Certificates shall
have been issued pursuant to Section 9.07, the relevant Trustees shall give all
such notices and communications, specified herein to be given to Preferred
Securities Holders, to the Clearing Agency and, with respect to any Preferred
Security Certificate registered in the name of a Clearing Agency or the nominee
of a Clearing Agency, the Trustees shall, except as set forth herein have no
notice obligations to the Preferred Security Beneficial Owners.

                  SECTION 9.06. Appointment of Successor Clearing Agency. If any
Clearing Agency elects to discontinue its services as securities depository with
respect to the Preferred Securities, the Regular Trustees may, in their sole
discretion, appoint a successor Clearing Agency with respect to the Preferred
Securities.

                  SECTION 9.07. Definitive Preferred Securities Certificates. If
(i) a Clearing Agency elects to discontinue its services as securities
depository with respect to the Preferred Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 9.06 or (ii) the Regular Trustees elect after consultation with the
Sponsor to terminate the book entry system through the Clearing Agency with
respect to the Preferred Securities, then (x) Definitive Preferred Security
Certificates shall be prepared by the Regular Trustees on behalf of the Trust
with respect to such Preferred Securities and (y) upon surrender of the Global
Certificates by the Clearing Agency, accompanied by registration instructions,
the Regular Trustees shall cause definitive Preferred Security Certificates to
be delivered to Preferred Security Beneficial Owners in accordance with the
instructions of the Clearing Agency. Neither the Trustees nor the Trust shall be
liable for any delay in delivery of such instructions and each of them may
conclusively rely on, and shall be protected in relying on, such instructions.

                  SECTION 9.08.  Mutilated, Destroyed, Lost or Stolen

Regular Trustees, or if the

Regular Trustees shall receive evidence to their satisfaction of the
destruction, loss or theft of any Certificate and (b) there shall be delivered
to the Regular Trustees such security or indemnity as may be required by them to
keep each of them harmless, then in the absence of notice that such Certificate
shall have been acquired by a bona fide purchaser, any two Regular Trustees on
behalf of the Trust shall execute and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination. In connection with the issuance of any new Certificate under this
Section 9.08, the Regular Trustees may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

Sponsor, PWG, the Delaware Trustee and the Property Trustee may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the Holders of Securities shall have no rights by
virtue of this Declaration in and to such independent ventures or the income or
profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper. None of the Covered Persons, the Sponsor, PWG, the Delaware Trustee or
the Property Trustee shall be obligated to present any particular investment or
other opportunity to the Trust even if such opportunity is of a character that,
if presented to the Trust, could be taken by the Trust, and any Covered Person,

Regular Trustees shall keep, or cause to be kept, full books of account, records
and supporting documents, which shall reflect in reasonable detail each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles consistently applied. The Trust shall use the accrual method of
accounting for United States Federal income tax purposes. The books and records
of the Trust, together with a copy of this Declaration and a certified copy of
the Certificate of Trust, or any amendment thereto, shall at all times be
maintained at the principal office of the Trust and shall be open for inspection
for any examination by any Holder or its duly authorized representative for any
purpose reasonably related to its interest in the Trust during normal business
hours.

                  (b) The Regular Trustees shall, as soon as available after the
end of each Fiscal Year of the Trust, cause to be prepared and mailed to each
Holder of Securities unaudited financial statements of the Trust for such Fiscal
Year, prepared in accordance with generally accepted accounting principles;
provided that if the Trust is required to comply with the periodic reporting
requirements of Sections 13(a) or 15(d) of the Exchange Act, such financial
statements for such Fiscal Year shall be examined and reported on by a firm of
independent certified public accountants selected by the Regular Trustees (which
firm may be the firm used by the Sponsor).

                  (c) The Regular Trustees shall cause to be prepared and mailed
to each Holder of Securities an annual United States Federal income tax
information statement, on such form as is required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations. Notwithstanding any right under the Code
to deliver any such statement at a later date, the Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

                  (d) The Regular Trustees shall cause to be prepared and filed
with the appropriate taxing authority an annual United States Federal income tax
return, on such form as is required by the Code, and any other annual income tax
returns required to be filed by the Regular Trustees on behalf of the Trust with
any state or local taxing

Fiscal Year of the Trust.

                  SECTION 11.03. Banking. The Trust shall maintain one or more
bank accounts in the name and for the sole benefit of the Trust; provided,
however, that all payments of funds in respect of the Debentures held by the
Property Trustee shall be made directly to the Property Account and no other
funds from the Trust shall be deposited in the Property Account. The sole
signatories for such accounts shall be designated by the Regular Trustees;
provided, however, that the Property Trustee shall designate the sole
signatories for the Property Account.

                  SECTION 11.04. Withholding. The Trust and the Trustees shall
comply with all withholding requirements under United States Federal, state and
local law. The Trust shall request, and the Holders shall provide to the Trust,
such forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Property Trustee
shall file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, the Property Trustee shall
remit amounts withheld with respect to the Holder to applicable jurisdictions.
To the extent that the Trust is required to withhold and pay over any amounts to
any authority with respect to distributions or allocations to any Holder, the
amount withheld shall be deemed to be a distribution in the amount of the
withholding to the Holder. In the event of any claimed overwithholding, Holders
shall be limited to an action against the applicable jurisdiction. If the amount
to be withheld was not withheld from a Distribution, the Property Trustee may
reduce subsequent Distributions by the amount of such withholding.

Trustees, both Regular Trustees); provided, however, that (i) no amendment to
this Declaration shall be made unless the Regular Trustees shall have obtained
(A) either a ruling from the Internal Revenue Service or a written unqualified
opinion of nationally recognized independent tax counsel experienced in such
matters to the effect that such amendment will not cause the Trust to be
classified for United States Federal income tax purposes as an association
taxable as a corporation or a partnership and to the effect that the Trust will
continue to be treated as a grantor trust for purposes of United States Federal
income taxation and (B) a written unqualified opinion of nationally recognized
independent counsel experienced in such matters to the effect that such
amendment will not cause the Trust to be an Investment Company which is required
to be registered under the Investment Company Act, (ii) if Securities are
outstanding, any amendment which would adversely affect the rights, privileges
or preferences of any Holder of Securities may be effected only after
satisfaction of such additional requirements as may be set forth in the terms of
such Securities, (iii) Section 4.02, Section 9.01(c) and this Section 12.01
shall not be amended without the consent of all Holders of the Securities, (iv)
no amendment which adversely affects the rights, powers and privileges of the
Property Trustee or the Delaware Trustee shall be made without the consent of
the Property Trustee or the Delaware Trustee, as the case may be, (v) Article IV
shall not be amended without the consent of the Sponsor, and (vi) the rights of
Holders of Common Securities under Article V to increase or decrease the number

be defective or inconsistent with any other provision of this Declaration, (iii)
to add to the covenants, restrictions or obligations of the Sponsor, and (iv) to
conform to any changes in Rule 3a-7 or any change in interpretation or
application of Rule 3a-7 by the Commission, which amendment does not adversely
affect the rights, preferences or privileges of the Holders.

                  (c) The Regular Trustees shall promptly furnish to each of the
Property Trustee and the Delaware Trustee a copy of each amendment to this
Declaration.

                  SECTION 12.02. Meetings of the Holders of Securities; Action
by Written Consent. (a) Meetings of the Holders of Preferred Securities and/or
Common Securities may be called at any time by the Regular Trustees (or as
provided in the terms of the Securities) to consider and act on any matter on
which Holders of such class of Securities are entitled to act under the terms of
this Declaration, the terms of the Securities or the rules of any stock exchange
on which the Preferred Securities are listed or admitted for trading. The
Regular Trustees shall call a meeting of Holders of Preferred Securities or
Common Securities if directed to do so by Holders of at least 10% in liquidation
amount of such class of Securities. Such direction shall be given by delivering
to the Regular Trustees one or more notices in writing stating that the signing
Holders of Securities wish to call a meeting and indicating the general or
specific purpose for which the meeting is to be called. Any Holders of
Securities calling a meeting shall specify in writing the Certificates held by
the Holders of Securities exercising the right to call a meeting and only those
specified Certificates shall be counted for purposes of determining whether the
required percentage set forth in the second sentence of this paragraph has been
met.

                  (b) Except to the extent otherwise provided in the terms of
the Securities, the following provision shall apply to meetings of Holders of
Securities:

                  (i) Notice of any such meeting shall be given by mail to each
         Trustee and all the Holders of Securities having a right to vote
         thereat not less than seven days nor more than 60 days prior to the
         date of such meeting. Whenever a vote, consent or approval of the
         Holders of Securities is permitted or required under this Declaration
         or the rules of any stock exchange on which the Preferred Securities
         are listed or admitted for trading, such vote, consent or approval may
         be given at a meeting of the Holders of Securities. Any action that may
         be taken at a meeting of the Holders of Securities may be taken without
         a meeting if a consent in writing setting forth the action so taken is
         signed by Holders of Securities owning not less than the minimum
         aggregate liquidation amount of Securities that would be necessary to
         authorize or take such action at





    
<PAGE>   58
                                                                              51










         a meeting at which all Holders of Securities having a right to vote
         thereon were present and voting. Prompt notice of the taking of action
         without a meeting shall be given to the Holders of Securities entitled
         to vote who have not consented in writing. The Regular Trustees may
         specify that any written ballot submitted to the Holders of Securities
         for the purpose of taking any action without a meeting shall be
         returned to the Trust within the time specified by the Regular
         Trustees.

             (ii) Each Holder of a Security may authorize any Person to act for
         it by proxy on all matters in which a Holder of a Security is entitled
         to participate, including waiving notice of any meeting, or voting or
         participating at a meeting. No proxy shall be valid after the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy. Every proxy shall be revocable at the pleasure of the
         Holder of Security executing it. Except as otherwise provided herein or
         in the terms of the Securities, all matters relating to the giving,
         voting or validity of proxies shall be governed by the General
         Corporation Law of the State of Delaware relating to proxies and
         judicial interpretations thereunder as if the Trust were a Delaware
         corporation and the Holders of the Securities were stockholders of a
         Delaware corporation.

            (iii) Each meeting of the Holders of the Securities shall be
         conducted by the Regular Trustees or by such other Person that the
         Regular Trustees may designate.

             (iv) Unless otherwise provided in the Business Trust Act, this
         Declaration or the rules of any stock exchange on which the Preferred
         Securities are then listed or admitted for trading, the Regular
         Trustees, in their sole discretion, shall establish all other
         provisions relating to meetings of Holders of Securities, including
         notice of the time, place or purpose of any meeting at which any matter
         is to be voted on by any Holders of Securities, waiver of any such
         notice, action by consent without a meeting, the establishment of a
         record date, quorum requirements, voting in person or by proxy or any
         other matter with respect to the exercise of any such right to vote.

         to applicable bankruptcy, reorganization, moratorium, insolvency, and
         other similar laws affecting creditors' rights generally and to general
         principles of equity and the discretion of the court (regardless of
         whether the enforcement of such remedies is considered in a proceeding
         in equity or at law).

            (iii) The execution, delivery and performance of this Declaration by
         the Property Trustee does not conflict with or constitute a breach of
         the charter or By-laws of the Property Trustee.

             (iv) No consent, approval or authorization of, or registration with
         or notice to, any banking authority which supervises or regulates the

         by the Property Trustee of this Declaration.

                                    TERMS OF
                              PREFERRED SECURITIES

                  Pursuant to Section 7.01 of the Amended and Restated
Declaration of Trust of PWG Capital Trust [ ] dated as of , 199 (as amended from
time to time, the "Declaration"), the designations, rights, privileges,
restrictions, preferences and other terms and provisions of the Preferred
Securities are set forth below (each capitalized term used but not defined
herein having the meaning set forth in the Declaration):

                  1. Designation and Number. Preferred Securities of the Trust
with an aggregate liquidation amount in the assets of the Trust of      Dollars
     ($      )(including up to       Dollars ($      ) issuable upon exercise
of the overallotment option set forth in the Underwriting Agreement) and a
liquidation amount in the assets of the Trust of $25 per Preferred Security are
hereby designated as " % Preferred Trust Securities". The Preferred Security
Certificates evidencing the Preferred Securities shall be substantially in the
form attached hereto as Annex I, with such changes and additions thereto or
deletions therefrom as may be required by ordinary usage, custom or practice or
to conform to the rules of any stock exchange on which the Preferred Securities
are listed. In connection with the issuance and sale of the Preferred Securities
and the Common Securities, the Trust will purchase, as trust assets, Debentures
of PWG having an aggregate principal amount equal to the aggregate liquidation
amount of the Preferred Securities and the Common Securities so issued and
bearing interest at an annual rate equal to the annual Distribution rate on the
Preferred Securities and the Common Securities and having payment and redemption
provisions which correspond to the payment and redemption provisions of the
Preferred Securities and the Common Securities.

                  2.  Distributions.  (a)  Distributions payable on
each Preferred Security will be fixed at a rate per annum of
   % (the "Coupon Rate") of the stated liquidation amount of $25 per Preferred
Security. Distributions in arrears for more than one month will bear interest at
the rate per annum of % thereof (to the extent permitted by law), compounded
monthly. The term "Distributions" as used in these terms means such periodic
cash distributions and any such interest payable unless otherwise stated. A
Distribution will be made by the Property Trustee only to the extent that





    
<PAGE>   71
                                                                               2










interest payments are made in respect of the Debentures held by the Property
Trustee. The amount of Distributions payable for any period will be computed for
any monthly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any period shorter than a 30-day monthly Distribution period for
which Distributions are computed, Distributions will be computed on the basis of
the actual number of days elapsed.

                  (b) Distributions on the Preferred Securities will be
cumulative, will accrue from           , 199  and will be payable monthly in
arrears, on the last day of each month commencing on          , 199 , except as
otherwise described below, but only if and to the extent that interest payments
are made in respect of the Debentures held by the Property Trustee. So long as
PWG is not in default in the payment of interest on the Debentures, PWG shall
have the right under the Indenture for the Debentures to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not to exceed 60 consecutive monthly interest periods
(an "Extension Period"), provided, however, that an Extension Period may not
extend beyond the maturity of the Debentures. During any such Extension Period,
monthly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the rate of    % per annum, compounded
monthly. Prior to the termination of any such Extension Period, PWG may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 60 consecutive
monthly interest periods. Upon the termination of any Extension Period and the
payment of all amounts then due, PWG may commence a new Extension Period,
subject to the above requirements. Payments of accrued Distributions will be
payable to Holders of Preferred Securities as they appear on the books and
records of the Trust on the record date for the first interest payment date
occurring at or after the end of the Extension Period.

                  (c) Distributions on the Preferred Securities will be payable
promptly by the Property Trustee (or other Paying Agent) upon receipt of
immediately available funds to the Holders thereof as they appear on the books
and records of the Trust on the relevant record dates. While the Preferred
Securities remain in book-entry only form, the relevant record dates shall be
one Business Day prior to the relevant Distribution date, and if the Preferred
Securities are no longer in book-entry only form, the relevant record





    
<PAGE>   72
                                                                               3










dates will be the fifteenth (15th) day of the month immediately preceding the
month in which the relevant Distribution date occurs, which record and payment
dates correspond to the record and interest payment dates for the Debentures.
Distributions payable on any Preferred Securities that are not punctually paid
on any Distribution payment date as a result of PWG having failed to make the
corresponding interest payment on the Debentures will forthwith cease to be
payable to the Person in whose name such Preferred Security is registered on the
relevant record date, and such defaulted Distribution will instead be payable to
the Person in whose name such Preferred Security is registered on the special
record date established by the Regular Trustees, which record date shall
correspond to the special record date or other specified date determined in
accordance with the Indenture; provided, however, that Distributions shall not
be considered payable on any Distribution payment date falling within an
Extension Period unless PWG has elected to make a full or partial payment of
interest accrued on the Debentures on such Distribution payment date. Subject to
any applicable laws and regulations and the provisions of the Declaration, each
payment in respect of the Preferred Securities will be made as described in
paragraph 9 hereof. If any date on which Distributions are payable on the
Preferred Securities is not a Business Day, then payment of the Distribution
payable on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay)
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.

                  (d) All Distributions paid with respect to the Preferred
Securities and the Common Securities will be paid pro rata to the Holders
thereof entitled thereto. If an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to Distributions.

                  (e) In the event that there is any money or other property
held by or for the Trust that is not accounted for under the Declaration, such
money or property shall be distributed pro rata among the Holders of the
Preferred Securities and the Common Securities.

                  3.  Liquidation Distribution upon Dissolution.  In
the event of any voluntary or involuntary dissolution,





    
<PAGE>   73
                                                                               4










winding-up or termination of the Trust, the Holders of the Preferred Securities
and the Common Securities at the date of the dissolution, winding-up or
termination, as the case may be, will be entitled to receive pro rata solely out
of the assets of the Trust available for distribution to Holders of Preferred
Securities and Common Securities after satisfaction of liabilities to creditors,
an amount equal to the aggregate of the stated liquidation amount of $25 per
Preferred Security and Common Security plus accrued and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such dissolution, winding-up or
termination, and after satisfaction of liabilities to creditors, Debentures in
an aggregate principal amount equal to the aggregate stated liquidation amount
of such Preferred Securities and Common Securities and bearing accrued and
unpaid interest in an amount equal to the accrued and unpaid Distributions on
such Preferred Securities and Common Securities, shall be distributed pro rata
to the Holders of the Preferred Securities and Common Securities in exchange for
such Securities.

                  If, upon any such dissolution, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets available to
pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Preferred Securities and the Common Securities
shall be paid, subject to the next paragraph, on a pro rata basis.

                  Holders of Common Securities will be entitled to receive
Liquidation Distributions upon any such dissolution pro rata with Holders of
Preferred Securities, except that, if an Event of Default has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities with respect to such Liquidation Distribution.

                  4. Redemption and Distribution of Debentures. The Preferred
Securities and the Common Securities may only be redeemed if Debentures having
an aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities and the Common Securities are repaid, redeemed or
distributed as set forth below:

                  (a) Upon the repayment of the Debentures, in whole or in part,
whether at maturity or upon redemption at any time or from time to time on or
after                , 200 , the proceeds of such repayment will be promptly





    
<PAGE>   74
                                                                               5










applied to redeem pro rata Preferred Securities and Common Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid, upon not less than 30 nor more than 60 days notice, at a
redemption price of $25 per Preferred and Common Security plus an amount equal
to accrued and unpaid Distributions thereon to the date of redemption, payable
in cash (the "Redemption Price"). The date of any such repayment of Preferred
Securities and Common Securities shall be established to coincide with the
repayment date of the Debentures.

                  (b) If fewer than all the outstanding Preferred Securities and
Common Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed pro rata, it being understood that Preferred
Securities held of record by a Clearing Agency or nominee will be redeemed as
described in paragraph 4(f)(ii) below. If a partial redemption would result in
the delisting of the Preferred Securities by any national securities exchange or
other organization on which the Preferred Securities are then listed, PWG
pursuant to the Indenture, will only redeem Debentures in whole and the Trust
will only redeem the Preferred Securities in whole.

                  (c) If, at any time, a Tax Event or an Investment Company
Event (each as hereinafter defined, and each a "Special Event") shall occur and
be continuing, the Regular Trustees shall, unless the Debentures are redeemed in
the limited circumstances described below, dissolve the Trust and, after
satisfaction of creditors, cause Debentures held by the Property Trustee having
an aggregate principal amount equal to the aggregate stated liquidation amount
of, and bearing accrued and unpaid interest equal to accrued and unpaid
Distributions on, and having the same record date for payment as, the Preferred
Securities and the Common Securities, to be distributed to the Holders of the
Preferred Securities and the Common Securities on a pro rata basis in
liquidation of such Holders' interests in the Trust, within 90 days following
the occurrence of such Special Event (the "90 Day Period"); provided, however,
that in the case of the occurrence of a Tax Event, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on any then
applicable published revenue ruling of the Internal Revenue Service, to the
effect that the Holders of the Preferred





    
<PAGE>   75
                                                                               6










Securities will not recognize any gain or loss for United States Federal income
tax purposes as a result of the dissolution of the Trust and distribution of
Debentures; and provided further that, if at the time there is available to the
Trust the opportunity to eliminate, within the 90 Day Period, the Special Event
by taking some ministerial action, such as filing a form or making an election,
or pursuing some other similar reasonable measure that has no adverse effect on
the Trust, PWG or the Holders of the Preferred Securities (a "Ministerial
Action"), the Trust will pursue such Ministerial Action in lieu of dissolution.

                  If in the case of the occurrence of a Tax Event, (i) the
Regular Trustees have received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that PWG
would be precluded from deducting the interest on the Debentures for United
States Federal income tax purposes even if the Debentures were distributed to
the Holders of Preferred Securities and Common Securities in liquidation of such
Holder's interest in the Trust as described in this paragraph 4(c) or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, PWG shall have the right
at any time, upon not less than 30 nor more than 60 days notice, to redeem the
Debentures in whole or in part for cash at the Redemption Price within 90 days
following the occurrence of such Tax Event, and, promptly following such
redemption, Preferred Securities and Common Securities with an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
redeemed will be redeemed by the Trust at the Redemption Price on a pro rata
basis; provided, however, that, if at the time there is available to PWG or the
Regular Trustees on behalf of the Trust the opportunity to eliminate, within
such 90 day period, the Tax Event by taking some Ministerial Action, PWG or the
Regular Trustees on behalf of the Trust will pursue such measure in lieu of
redemption; and provided further that PWG shall have no right to redeem the
Debentures while the Regular Trustees on behalf of the Trust are pursuing such
Ministerial Action. The Common Securities will be redeemed pro rata with the
Preferred Securities, except that if an Event of Default under the Indenture has
occurred and is continuing, the Preferred Securities will have a priority over
the Common Securities with respect to payment of the Redemption Price.

                  "Tax Event" means that the Regular Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such matters (a "Dissolution Tax Opinion") to the effect that, on or after
            , 199 , as a result of (a) 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, (b) any amendment to, or change (including any announced prospective
change) in, an interpretation or application of any such laws or regulations by
any legislative body, court, governmental agency or regulatory authority
(including the enactment of any legislation and the publication of any judicial
decision or regulatory determination), (c) any interpretation or pronouncement
that provides for a position with respect to such laws or regulations that
differs from the theretofore generally accepted position or (d) any action taken
by any governmental agency or regulatory authority, which amendment or change is
enacted, promulgated, issued or effective or which interpretation or
pronouncement is issued or announced or which action is taken, in each case on
or after
            , 199 , there is more than an insubstantial risk that (i) the Trust
is, or will be within 90 days of the date thereof, subject to United States
Federal income tax with respect to income accrued or received on the Debentures,
(ii) the Trust is, or will be within 90 days of the date thereof, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges or (iii) interest payable by PWG to the Trust on the Debentures is not,
or within 90 days of the date thereof will not be, deductible by PWG for United
States Federal income tax purposes.

                  "Investment Company Event" means that the Regular Trustees
shall have received an opinion of nationally recognized independent counsel
experienced in practice under the Investment Company Act that, as a result of
the occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), there is more than
an insubstantial risk that the Trust is or will be considered an Investment
Company which is required to be registered under the Investment Company Act,
which Change in 1940 Act Law becomes effective on or after              , 199 .

                  On the date fixed for any distribution of    Debentures, upon
dissolution of the Trust, (i) the Preferred Securities will no longer be deemed
to be outstanding, and (ii) certificates representing Preferred Securities will
be deemed to represent beneficial interests in the Debentures having an
aggregate principal amount equal to the stated liquidation amount of, and
bearing accrued and unpaid interest equal to accrued and unpaid Distributions
on, such Preferred Securities until such certificates are presented to PWG or
its agent for transfer or reissuance.

                  (d) The Trust may not redeem fewer than all the outstanding
Preferred Securities unless all accrued and unpaid Distributions have been paid
on all Preferred Securities for all monthly Distribution periods terminating on
or prior to the date of redemption.

                  (e) If Debentures are distributed to Holders of the Preferred
Securities, PWG, pursuant to the terms of the Indenture, will use its best
efforts to have the Debentures listed on the New York Stock Exchange or on such
other exchange as the Preferred Securities were listed immediately prior to the
distribution of the Debentures.

                  (f)(i) Notice of any redemption of, or notice of distribution
of Debentures in exchange for, the Preferred Securities and the Common
Securities (a "Redemption/Distribution Notice") will be given by the Regular
Trustees on behalf of the Trust by mail to each Holder of Preferred Securities
and Common Securities to be redeemed or exchanged not less than 30 nor more than
60 days prior to the date fixed for redemption or exchange thereof. For purposes
of the calculation of the date of redemption or exchange and the dates on which
notices are given pursuant to this paragraph (f)(i), a Redemption/Distribution
Notice shall be deemed to be given on the day such notice is first mailed by
first class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities. Each Redemption/Distribution Notice shall be addressed to the
Holders of Preferred Securities and Common Securities at the address of each
such Holder appearing in the books and records of the Trust. No defect in the
Redemption/Distribution Notice or in the mailing of either thereof with respect
to any Holder shall affect the validity of the redemption or exchange
proceedings with respect to any other Holder.

                                                                               9










                  (ii) In the event that fewer than all the outstanding
Preferred Securities are to be redeemed, the Preferred Securities to be redeemed
will be redeemed pro rata from each Holder of Preferred Securities, it being
understood that, in respect of Preferred Securities registered in the name of
and held of record by DTC (or a successor Clearing Agency) or any other nominee,
the Preferred Securities will be redeemed from, and the distribution of the
proceeds of such redemption will be made to, each Clearing Agency Participant
(or person on whose behalf such nominee holds such securities) in accordance
with the procedures applied by such agency or nominee.

                  (iii) Subject to paragraph 9 hereof, if the Trust gives a
Redemption/Distribution Notice in respect of a redemption of Preferred
Securities as provided in this paragraph 4 (which notice will be irrevocable)
then (A) while the Preferred Securities are in book-entry only form, by 12:00
noon, New York City time, on the redemption date, provided that PWG has paid the
Property Trustee in immediately available funds a sufficient amount of cash in
connection with the related redemption or maturity of the Debentures, the
Property Trustee will deposit irrevocably with DTC (or any successor Clearing
Agency) funds sufficient to pay the applicable Redemption Price with respect to
the Preferred Securities and will give DTC (or any successor Clearing Agency)
irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Preferred Securities and (B) if the Preferred Securities are
issued in definitive form, and provided that PWG has paid the Property Trustee
in immediately available funds a sufficient amount of cash in connection with
the related redemption or maturity of the Debentures, the Property Trustee will
pay the relevant Redemption Price to the Holders of such Preferred Securities by
check mailed to the address of the relevant Holder appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given and funds deposited as required, if applicable, then
immediately prior to the close of business on the redemption date, Distributions
will cease to accrue on the Preferred Securities called for redemption, such
Preferred Securities will no longer be deemed to be outstanding and all rights
of Holders of such Preferred Securities so called for redemption will cease,
except the right of the Holders of such Preferred Securities to receive the
Redemption Price, but without interest on such Redemption Price. Neither the
Trustees nor the Trust shall be required to register or cause to be registered
the





    
<PAGE>   79
                                                                              10










transfer of any Preferred Securities which have been so called for redemption.
If any date fixed for redemption of Preferred Securities is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that 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 each case with the same force and effect as if made on such
date fixed for redemption. If PWG fails to repay Debentures on maturity or on
the date fixed for redemption or if payment of the Redemption Price in respect
of Preferred Securities is improperly withheld or refused and not paid either by
the Property Trustee or, pursuant to the Preferred Securities Guarantee, by PWG,
Distributions on such Preferred Securities will continue to accrue, from the
original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price.

                (iv) Redemption/Distribution Notices shall be sent by the
Regular Trustees on behalf of the Trust to DTC or its nominee (or any successor
Clearing Agency or its nominee) if the Global Certificates have been issued or,
if Definitive Preferred Security Certificates have been issued, to the Holders
of the Preferred Securities.

                  (v) Upon the date of dissolution of the Trust and distribution
of Debentures as a result of the occurrence of a Special Event, Preferred
Security Certificates shall be deemed to represent beneficial interests in the
Debentures so distributed, and the Preferred Securities will no longer be deemed
outstanding and may be canceled by the Regular Trustees. The Debentures so
distributed shall have an aggregate principal amount equal to the aggregate
liquidation amount of the Preferred Securities so distributed.

                (vi) If a partial redemption of the Preferred Securities would
result in the delisting of the Preferred Securities by any national securities
exchange or other organization on which the Preferred Securities are then
listed, the Company pursuant to the Indenture will only redeem Junior
Subordinated Debentures in whole and, as a result, the Trust would only redeem
the Preferred Securities in whole.

              (vii) Subject to the foregoing and applicable law (including,
without limitation, United States Federal securities laws), PWG or any of its
subsidiaries may at any time and from time to time purchase outstanding
Preferred Securities by tender, in the open market or by private
agreement.

                  5.  Voting Rights.  (a)  Except as provided under
paragraph 5(b) below and as otherwise required by law and
the Declaration, the Holders of the Preferred Securities
will have no voting rights.

                  (b) If any proposed amendment to the Declaration provides for,
or the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than in connection
with the distribution of Debentures held by the Property Trustee, upon the
occurrence of a Special Event or in connection with the redemption of Preferred
Securities as a consequence of a redemption of Debentures, then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such amendment or proposal shall not be effective except with the
approval of the Holders of Securities representing 66-2/3% in liquidation amount
of such Securities; provided, however, that (A) if any amendment or proposal
referred to in clause (i) above would adversely affect only the Preferred
Securities or the Common Securities, then only the affected class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of 66-2/3% in liquidation amount
of such class of Securities and (B) amendments to the Declaration shall be
subject to such further requirements as are set forth in Sections 12.01 and
12.02 of the Declaration.

                  In the event the consent of the Property Trustee, as the
holder of the Debentures, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture or the Debentures, the
Property Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination. The
Property Trustee shall vote with respect to such amendment, modification or
termination as directed by a Majority in liquidation amount of the Securities
voting together as a single class;





    
<PAGE>   81
                                                                              12










provided that where such amendment, modification or termination of the Indenture
requires the consent or vote of (1) holders of Debentures representing a
specified percentage greater than a majority in principal amount of the
Debentures or (2) each holder of Debentures, the Property Trustee may only vote
with respect to that amendment, modification or termination as directed by, in
the case of clause (1) above, the vote of Holders of Securities representing
such specified percentage of the aggregate liquidation amount of the Securities,
or, in the case of clause (2) above, each Holder of Securities; and provided
further that the Property Trustee shall be under no obligation to take any
action in accordance with the directions of the Holders of Securities unless the
Property Trustee shall have received, at the expense of the Sponsor, an opinion
of nationally recognized independent tax counsel recognized as expert in such
matters to the effect that the Trust will not be classified for United States
Federal income tax purposes as an association taxable as a corporation or a
partnership on account of such action and will be treated as a grantor trust for
United States Federal income tax purposes following such action.

                  Subject to Section 2.06 of the Declaration, and the provisions
of this and the next succeeding paragraph, the Holders of a Majority in
liquidation amount of the Preferred Securities, voting separately as a class,
shall have the right to (A) on behalf of all Holders of Preferred Securities,
waive any past default that is waivable under the Declaration (subject to, and
in accordance with, the Declaration) and (B) direct the time, method and place
of conducting any proceeding for any remedy available to the Property Trustee,
or exercising any trust or power conferred upon the Property Trustee under the
Declaration, including the right to direct the Property Trustee, as the holder
of the Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or exercising any
trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 6.06 of
the Indenture, or (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable; provided that
where the taking of any action under the Indenture requires the consent or vote
of (1) holders of Debentures representing a specified percentage greater than a
majority in principal amount of the Debentures or (2) each holder of Debentures,
the Property Trustee may only take such action





    
<PAGE>   82
                                                                              13










if directed by, in the case of clause (1) above, the vote of Holders of
Preferred Securities representing such specified percentage of the aggregate
liquidation amount of the Preferred Securities, or, in the case of clause (2)
above, each Holder of Preferred Securities. The Property Trustee shall not
revoke any action previously authorized or approved by a vote of the Holders of
the Preferred Securities. Other than with respect to directing the time, method
and place of conducting any proceeding for any remedy available to the Property
Trustee or the Debenture Trustee as set forth above, the Property Trustee shall
be under no obligation to take any of the foregoing actions at the direction of
the Holders of Preferred Securities unless the Property Trustee shall have
received, at the expense of the Sponsor, an opinion of nationally recognized
independent tax counsel recognized as expert in such matters to the effect that
the Trust will not be classified for United States Federal income tax purposes
as an association taxable as a corporation or a partnership on account of such
action and will be treated as a grantor trust for United States federal income
tax purposes following such action. If the Property Trustee fails to enforce its
rights under the Declaration (including, without limitation, its rights, powers
and privileges as a holder of the Debentures under the Indenture), any Holder of
Preferred Securities may, to the extent permitted by law, after a period of 30
days has elapsed from such Holder's written request to the Property Trustee to
enforce such rights, institute a legal proceeding directed against PWG to
enforce the Property Trustee's rights under the Declaration, without first
instituting a legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of PWG to pay interest
or principal on the Debentures on the date such interest or principal is
otherwise payable (or in the case of redemption, the redemption date), then a
Holder of Preferred Securities may directly institute suit against the Company
for enforcement of payment to such Holder of the principal of or interest on
Debentures having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities held by such Holder on or after the respective due
date specified in the Debentures. The Holders of Preferred Securities will not
be able to exercise directly against PWG any other remedy available to the
Holders of the Debentures unless the Property Trustee first fails to do so.






    
<PAGE>   83
                                                                              14










                  A waiver of an Indenture Event of Default by the Property
Trustee at the direction of the Holders of the Preferred Securities will
constitute a waiver of the corresponding Event of Default under the Declaration
in respect of the Securities.

                  Any required approval or direction of Holders of Preferred
Securities may be given at a separate meeting of Holders of Preferred Securities
convened for such purpose, at a meeting of all of the Holders of Securities of
the Trust or pursuant to written consent. The Regular Trustees will cause a
notice of any meeting at which Holders of Preferred Securities are entitled to
vote, or of any matter upon which action by written consent of such Holders is
to be taken, to be mailed to each Holder of record of Preferred Securities. Each
such notice will include a statement setting forth (i) the date of such meeting
or the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                  No vote or consent of the Holders of Preferred Securities will

relative to the aggregate liquidation amount of all Common Securities
outstanding.

                  7. Ranking. The Preferred Securities rank pari passu and

where an Event of Default occurs and is continuing, the rights of Holders of
Preferred Securities to payment in respect of Distributions and payments upon
liquidation, redemption or otherwise rank in priority to the rights of Holders
of the Common Securities.

                  8. Mergers, Consolidations or Amalgamations. The Trust may not

                                    TERMS OF
                                COMMON SECURITIES


                  Pursuant to Section 7.01 of the Amended and Restated
Declaration of Trust of PWG Capital Trust [ ] dated as of , 199 (as amended from
time to time, the "Declaration"), the designations, rights, privileges,
restrictions, preferences and other terms and provisions of the Common
Securities are set forth below (each capitalized term used but not defined
herein having the meaning set forth in the Declaration):

                  1. Designation and Number. Common Securities of the Trust with
an aggregate liquidation amount in the assets of the Trust of Dollars ($ )
(including up to Dollars ($ ) issuable upon exercise of the overallotment option
set forth in the Underwriting Agreement) and a liquidation amount in the assets
of the Trust of $25 per Common Security are hereby designated as " % Common
Trust Securities". The Common Security Certificates evidencing the Common
Securities shall be substantially in the form attached hereto as Annex I, with
such changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice. The Common Securities are to be issued and
sold to Paine Webber Group Inc. ("PWG") in consideration of $ in cash. In
connection with the issuance and sale of the Preferred Securities and the Common
Securities, the Trust will purchase, as trust assets, Debentures of PWG having
an aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities and the Common Securities so issued, and bearing interest
at an annual rate equal to the annual Distribution rate on the Preferred
Securities and the Common Securities and having payment and redemption
provisions which correspond to the payment and redemption provisions of the
Preferred Securities and the Common Securities.

                  2.  Distributions.  (a)  Distributions payable on each Common
Security will be fixed at a rate per annum of % (the "Coupon Rate") of the
stated liquidation amount of $25 per Common Security.  Distributions in arrears
for more than one month will bear interest at the rate per annum of %   thereof
(to the extent permitted by applicable law), compounded monthly.  The term
"Distributions" as used in these terms means such periodic cash distributions
and any such interest payable unless otherwise stated.  A





    
<PAGE>   91
                                                                               2










Distribution will be made by the Property Trustee only to the extent that
interest payments are made in respect of the Debentures held by the Property
Trustee. The amount of Distributions payable for any period will be computed for
any monthly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any Distribution period shorter than a 30-day monthly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed.

                  (b) Distributions on the Common Securities will be cumulative,
will accrue from , 199 and will be payable monthly in arrears, on the last day
of each month, commencing on , 199 , except as otherwise described below, but
only if and to the extent that interest payments are made in respect of the
Debentures held by the Property Trustee. So long as PWG is not in default in the
payment of interest on the Debentures, PWG shall have the right under the
Indenture for the Debentures to defer payments of interest by extending the
interest payment period from time to time on the Debentures for a period not to
exceed 60 consecutive monthly interest periods (each, an "Extension Period"),
provided, however, that an Extension Period may not extend beyond the maturity
of the Debentures. During any such Extension Period, monthly Distributions will
continue to accrue with interest thereon (to the extent permitted by applicable
law) at the rate of % per annum, compounded monthly. Prior to the termination of
any such Extension Period, PWG may further extend such Extension Period;
provided that such Extension Period, together with all such previous and further
extensions thereof, may not exceed 60 consecutive monthly interest periods. Upon
the termination of any Extension Period and the payment of all amounts then due,
PWG may commence a new Extension Period, subject to the above requirements.
Payments of accrued Distributions will be payable to Holders of Common
Securities as they appear on the books and records of the Trust on the record
date for the first interest payment date occurring at or after the end of the
Extension Period.

                  (c) Distributions on the Common Securities will be payable
promptly by the Property Trustee (or other Paying Agent) upon receipt of
immediately available funds to the Holders thereof as they appear on the books
and records of the Trust on the relevant record dates which will be one Business
Day prior to the relevant Distribution date unless the Preferred Securities are
no longer in book-entry only form, in which event the relevant record dates will
be the





    
<PAGE>   92
                                                                               3










fifteenth (15th) day of the month immediately preceding the month in which the
relevant Distribution date occurs, which record and payment dates correspond to
the record and interest payment dates for the Debentures. Distributions payable
on any Common Securities that are not punctually paid on any Distribution date
as a result of PWG having failed to make the corresponding interest payment on
the Debentures will forthwith cease to be payable to the Person in whose name
such Common Security is registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Common Security is registered on the special record date established by the
Regular Trustees, which record date shall correspond to the special record date
or other specified date determined in accordance with the Indenture; provided,
however, that Distributions shall not be considered payable on any Distribution
payment date falling within an Extension Period unless PWG has elected to make a
full or partial payment of interest accrued on the Debentures on such
Distribution payment date. Subject to any applicable laws and regulations and
the provisions of the Declaration, each payment in respect of the Common
Securities will be made as described in paragraph 9 hereof. If any date on which
Distributions are payable on the Common Securities is not a Business Day, then
payment of the Distribution payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

                  (d) All Distributions paid with respect to the Common
Securities and the Preferred Securities will be paid pro rata to the Holders
thereof entitled thereto. If an Event of Default has occurred and is continuing,
the Preferred Securities shall have a priority over the Common Securities with
respect to Distributions.

                  (e) In the event that there is any money or other property
held by or for the Trust that is not accounted for under the Declaration, such
money or property shall be distributed pro rata among the Holders of the
Preferred Securities and the Common Securities.

                  3.  Liquidation Distribution Upon Dissolution. In the event of
any voluntary or involuntary dissolution, winding-up or termination of the
Trust, the Holders of the





    
<PAGE>   93
                                                                               4










Preferred Securities and Common Securities at the date of the dissolution,
winding-up or termination, as the case may be, will be entitled to receive pro
rata solely out of the assets of the Trust available for distribution to Holders
of Preferred Securities and the Common Securities, after satisfaction of
liabilities to creditors, an amount equal to the aggregate of the stated
liquidation amount of $25 per Preferred Security and Common Security plus
accrued and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
dissolution, winding-up or termination, and after satisfaction of liabilities to
creditors, Debentures in an aggregate principal amount equal to the aggregate
stated liquidation amount of such Preferred Securities and Common Securities
bearing accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on, such Preferred Securities and Common Securities, shall be
distributed pro rata to the Holders of the Preferred Securities and Common
Securities in exchange for such Securities.

                  If, upon any such dissolution, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets available to
pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Preferred Securities and the Common Securities
shall be paid, subject to the next paragraph, on a pro rata basis.

                  Holders of Common Securities will be entitled to receive
Liquidation Distributions upon any such dissolution pro rata with Holders of
Preferred Securities, except that, if an Event of Default has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities with respect to such Liquidation Distribution.

                  4. Redemption and Distribution of Debentures. The Preferred
Securities and the Common Securities may only be redeemed if Debentures having
an aggregate principal amount equal to the aggregate liquidation amount of the
Preferred Securities and the Common Securities are repaid, redeemed or
distributed as set forth below:

                  (a) Upon the repayment of the Debentures, in whole or in part,
whether at maturity or upon redemption at any time or from time to time on or
after, 200 , the proceeds of such repayment will be promptly applied to redeem
pro rata Preferred Securities and Common Securities





    
<PAGE>   94
                                                                               5










having an aggregate liquidation amount equal to the aggregate principal amount
of the Debentures so repaid, upon not less than 30 nor more than 60 days notice,
at a redemption price of $25 per Preferred and Common Security plus an amount
equal to accrued and unpaid Distributions thereon to the date of redemption,
payable in cash (the "Redemption Price"). The date of any such repayment of
Preferred Securities and Common Securities shall be established to coincide with
the repayment or redemption date of the Debentures.

                  (b) If fewer than all the outstanding Preferred Securities and
Common Securities are to be so redeemed, the Preferred Securities and the Common
Securities will be redeemed pro rata and, with respect to the Common Securities
to be redeemed, as described in paragraph 4(e)(ii) below. If a partial
redemption would result in the delisting of the Preferred Securities by any
national securities exchange or other organization on which the Preferred
Securities are then listed, PWG, pursuant to the Indenture, will only redeem
Debentures in whole and the Trust will only redeem the Common Securities in
whole.

                  (c) If, at any time, a Tax Event or an Investment Company
Event (each, as hereinafter defined and, each, a "Special Event") shall occur
and be continuing, the Regular Trustees shall, unless the Debentures are
redeemed in the limited circumstances described below, dissolve the Trust and,
after satisfaction of creditors, cause Debentures held by the Property Trustee
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, and bearing accrued and unpaid interest equal to accrued and unpaid
Distributions on, and having the same record date for payment as, the Preferred
Securities and the Common Securities, to be distributed to the Holders of the
Preferred Securities and the Common Securities on a pro rata basis in
liquidation of such Holders' interests in the Trust, within 90 days following
the occurrence of such Special Event (the "90 Day Period"); provided, however,
that in the case of the occurrence of a Tax Event, as a condition of such
dissolution and distribution, the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on any then
applicable published revenue rulings of the Internal Revenue Service, to the
effect that the Holders of the Preferred Securities will not recognize any gain
or loss for United States Federal income tax purposes as a result of the





    
<PAGE>   95
                                                                               6










dissolution of the Trust and distribution of Debentures; and provided further
that, if at the time there is available to the Trust the opportunity to
eliminate, within such 90 Day Period, the Special Event by taking some
ministerial action, such as filing a form or making an election, or pursuing
some other similar reasonable measure that has no adverse effect on the Trust,
PWG or the Holders of the Preferred Securities (a "Ministerial Action"), the
Trust will pursue such Ministerial Action in lieu of dissolution.

                  If in the case of the occurrence of a Tax Event, (i) the
Regular Trustees have received an opinion (a "Redemption Tax Opinion") of
nationally recognized independent tax counsel experienced in such matters that,
as a result of a Tax Event, there is more than an insubstantial risk that PWG
would be precluded from deducting the interest on the Debentures for United
States Federal income tax purposes even if the Debentures were distributed to
the Holders of Preferred Securities and Common Securities in liquidation of such
Holders' interest in the Trust as described in this paragraph 4(c) or (ii) the
Regular Trustees shall have been informed by such tax counsel that a No
Recognition Opinion cannot be delivered to the Trust, PWG shall have the right
at any time, upon not less than 30 nor more than 60 days notice, to redeem the
Debentures in whole or in part for cash at the Redemption Price within 90 days
following the occurrence of such Tax Event, and, promptly following such
redemption, Preferred Securities and Common Securities with an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures so
redeemed will be redeemed by the Trust at the Redemption Price on a pro rata
basis; provided, however, that, if at the time there is available to PWG or the
Regular Trustees on behalf of the Trust the opportunity to eliminate, within
such 90 Day Period, the Tax Event by taking some Ministerial Action, PWG or the
Holders of the Preferred Securities, PWG or the Regular Trustees, on behalf of
the Trust, will pursue such measure in lieu of redemption; and provided further,
that PWG shall have no right to redeem the Debentures while the Regular
Trustees, on behalf of the Trust, are pursuing such Ministerial Action. The
Common Securities will be redeemed pro rata with the Preferred Securities,
except that if an Event of Default under the Indenture has occurred and is
continuing, the Preferred Securities will have a priority over the Common
Securities with respect to payment of the Redemption Price.

                  "Tax Event" means that the Regular Trustees shall have
obtained an opinion of nationally recognized independent tax counsel experienced
in such matters (a "Dissolution Tax Opinion") to the effect that, on or after ,
199 as a result of (a) 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, (b)
any amendment to, or change (including any announced prospective change) in, an
interpretation or application of any such laws or regulations by any legislative
body, court, governmental agency or regulatory authority (including the
enactment of any legislation and the publication of any judicial decision or
regulatory determination), (c) any interpretation or pronouncement that provides
for a position with respect to such laws or regulations that differs from the
theretofore generally accepted position or (d) any action taken by any
governmental agency or regulatory authority, which amendment or change is
enacted, promulgated, issued or effective or which interpretation or
pronouncement is issued or announced or which action is taken, in each case on
or after            , 199 , there is more than an insubstantial risk that (i)
the Trust is, or will be within 90 days of the date thereof, subject to United
States Federal income tax with respect to income accrued or received on the
Debentures, (ii) the Trust is, or will be within 90 days of the date thereof,
subject to more than a de minimis amount of taxes, duties or other governmental
charges or (iii) interest payable by PWG to the Trust on the Debentures is not,
or within 90 days of the date thereof will not be, deductible by PWG for United
States Federal income tax purposes.

                  "Investment Company Event" means that the Regular Trustees
shall have received an opinion of nationally recognized independent counsel
experienced in practice under the Investment Company Act that, as a result of
the occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), there is more than
an insubstantial risk that the Trust is or will be considered an Investment
Company which is required to be registered under the Investment Company Act,
which Change in 1940 Act Law becomes effective on or after , 199 .

                  On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Common Securities will no longer be deemed to
be outstanding and (ii) any certificates representing Common Securities will be
deemed to represent beneficial interests in the Debentures having an aggregate
principal amount equal to the stated liquidation amount of, and bearing accrued
and unpaid interest equal to accrued and unpaid Distributions on, such Common
Securities until such certificates are presented to PWG or its agent for
transfer or reissuance.

                  (d) The Trust may not redeem fewer than all the outstanding
Common Securities unless all accrued and unpaid Distributions have been paid on
all Common Securities for all monthly Distribution periods terminating on or
prior to the date of redemption.

                  (e)(i) Notice of any redemption of, or notice of distribution
of Debentures in exchange for, the Preferred Securities and the Common
Securities (a "Redemption/Distribution Notice") will be given by the Regular
Trustees on behalf of the Trust by mail to each Holder of Preferred Securities
and Common Securities to be redeemed or exchanged not less than 30 nor more than
60 days prior to the date fixed for redemption or exchange thereof. For purposes
of the calculation of the date of redemption or exchange and the dates on which
notices are given pursuant to this paragraph (e)(i), a Redemption/Distribution
Notice shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to Holders of Preferred Securities and Common
Securities. Each Redemption/ Distribution Notice shall be addressed to the
Holders of Preferred Securities and Common Securities at the address of each
such Holder appearing in the books and records of the Trust. No defect in the
Redemption/Distribution Notice or in the mailing of either thereof with respect
to any Holder shall affect the validity of the redemption or exchange
proceedings with respect to any other Holder.

                (ii) In the event that fewer than all the outstanding Common
Securities are to be redeemed, the Common Securities to be redeemed will be
redeemed pro rata from each Holder of Common Securities (subject to adjustment
to eliminate fractional Common Securities).

              (iii)  If the Trust gives a Redemption/Distribution
Notice in respect of a redemption of Common Securities as





    
<PAGE>   98
                                                                               9










provided in this paragraph 4 (which notice will be irrevocable), then
immediately prior to the close of business on the redemption date, provided that
PWG has paid to the Property Trustee in immediately available funds a sufficient
amount of cash in connection with the related redemption or maturity of the
Debentures, Distributions will cease to accrue on the Common Securities called
for redemption, such Common Securities will no longer be deemed to be
outstanding and all rights of Holders of such Common Securities so called for
redemption will cease, except the right of the Holders of such Common Securities
to receive the Redemption Price, but without interest on such Redemption Price.
Neither the Trustees nor the Trust shall be required to register or cause to be
registered the transfer of any Common Securities which have been so called for
redemption. If any date fixed for redemption of Common Securities is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that 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 each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
in respect of Common Securities is improperly withheld or refused and not paid
by the Property Trustee, Distributions on such Common Securities will continue
to accrue, from the original redemption date to the date of payment, in which
case the actual payment date will be considered the date fixed for redemption
for purposes of calculating the Redemption Price.

                (iv)  Redemption/Distribution Notices shall be sent
by the Regular Trustees on behalf of the Trust to the
Holders of the Common Securities.

                  (v) Upon the date of dissolution of the Trust and distribution
of Debentures as a result of the occurrence of a Special Event, Common Security
Certificates shall be deemed to represent beneficial interests in the Debentures
so distributed, and the Common Securities will no longer be deemed outstanding
and may be canceled by the Regular Trustees. The Debentures so distributed shall
have an aggregate principal amount equal to the aggregate liquidation amount of
the Common Securities so distributed.

                  5.  Voting Rights.  (a)  Except as provided under
paragraph 5(b) below and as otherwise required by law and





    
<PAGE>   99
                                                                              10










the Declaration, the Holders of the Common Securities will
have no voting rights.

                  (b) Holders of Common Securities have the sole right under the
Declaration to increase or decrease the number of Trustees, and to appoint,
remove or replace a Trustee, any such increase, decrease, appointment, removal
or replacement to be approved by Holders of Common Securities representing a
Majority in liquidation amount of the Common Securities.

                  If any proposed amendment to the Declaration provides for, or
the Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than in connection
with the distribution of Debentures held by the Property Trustee, upon the
occurrence of a Special Event or in connection with the redemption of Common
Securities as a consequence of a redemption of Debentures, then the Holders of
outstanding Securities will be entitled to vote on such amendment or proposal as
a class and such amendment or proposal shall not be effective except with the
approval of the Holders of Securities representing 66-2/3% in liquidation amount
of such Securities; provided, however, that (A) if any amendment or proposal
referred to in clause (i) above would adversely affect only the Preferred
Securities or the Common Securities, then only the affected class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of 66-2/3 in liquidation amount
of such class of Securities, (B) the rights of Holders of Common Securities
under Article V of the Declaration to increase or decrease the number of, and to
appoint, replace or remove, Trustees shall not be amended without the consent of
each Holder of Common Securities, and (C) amendments to the Declaration shall be
subject to such further requirements as are set forth in Sections 12.01 and
12.02 of the Declaration.

                  In the event the consent of the Property Trustee as the holder
of the Debentures, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture or the Debentures, the
Property Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination. The
Property Trustee shall

                                                                              11










vote with respect to such amendment, modification or termination as directed by
a Majority in liquidation amount of the Securities voting together as a single
class; provided that where such amendment, modification or termination of the
Indenture requires the consent or vote of (1) holders of Debentures representing
a specified percentage greater than a majority in principal amount of the
Debentures or (2) each holder of Debentures, the Property Trustee may vote only
with respect to that amendment, modification or termination as directed by, in
the case of clause (1) above, the vote of Holders of Securities representing
such specified percentage of the aggregate liquidation amount of the Securities,
or, in the case of clause (2) above, each Holder of Securities; and provided,
further, that the Property Trustee shall be under no obligation to take any
action in accordance with the directions of the Holders of the Securities unless
the Property Trustee shall have received, at the expense of the Sponsor, an
opinion of nationally recognized independent tax counsel recognized as an expert
in such matters to the effect that the Trust will not be classified for United
States Federal income tax purposes as an association taxable as a corporation or
a partnership on account of such action and will be treated as a grantor trust
for United States Federal income tax purposes following such action.

                  Subject to Section 2.06 of the Declaration and the provisions
of this and the next succeeding paragraph, the Holders of a Majority in
liquidation amount of the Common Securities, voting separately as a class, shall
have the right to (A) on behalf of all Holders of Common Securities, waive any
past default that is waivable under the Declaration (subject to, and in
accordance with, the Declaration) and (B) direct the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee, or
exercising any trust or power conferred upon the Property Trustee under the
Declaration, including the right to direct the Property Trustee, as holder of
the Debentures, to (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or exercising any
trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default and its consequences that is waivable
under Section 6.06 of the Indenture, or (iii) exercise any right to rescind or
annul a declaration that the principal of all the Debentures shall be due and
payable; provided that where the taking of any action under the Indenture
requires the consent or vote of (1) holders of





    
<PAGE>   101
                                                                              12










Debentures representing a specified percentage greater than a majority in
principal amount of the Debentures or (e) each holder of Debentures, the
Property Trustee may take such action only if directed by, in the case of clause
(1) above, the vote of Holders of Common Securities representing such specified
percentage of the aggregate liquidation amount of the Common Securities, or, in
the case of clause (2) above, each Holder of Common Securities. Pursuant to this
paragraph, the Property Trustee shall not revoke, or take any action
inconsistent with, any action previously authorized or approved by a vote of the
Holders of the Preferred Securities, and shall not take any action in accordance
with the direction of the Holders of the Common Securities under this paragraph
if the action is prejudicial to the Holders of Preferred Securities. Other than
with respect to directing the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee or the Debenture
Trustee as set forth above, the Property Trustee shall be under no obligation to
take any of the foregoing actions at the direction of the Holders of Common
Securities unless the Property Trustee shall have received, at the expense of
the Sponsor, an opinion of nationally recognized independent tax counsel
recognized as expert in such matters to the effect that the Trust will not be
classified for United States Federal income tax purposes as an association
taxable as a corporation or a partnership on account of such action and will be
treated as a grantor trust for United States income tax purposes following such
action.

                  Notwithstanding any other provision of these terms, each
Holder of Common Securities will be deemed to have waived any Event of Default
with respect to the Common Securities and its consequences until all Events of
Default with respect to the Preferred Securities have been cured, waived by the
Holders of Preferred Securities as provided in the Declaration or otherwise
eliminated, and until all Events of Default with respect to the Preferred
Securities have been so cured, waived by the Holders of Preferred Securities or
otherwise eliminated, the Property Trustee will be deemed to be acting solely on
behalf of the Holders of Preferred Securities and only the Holders of the
Preferred Securities will have the right to direct the Property Trustee in
accordance with the terms of the Declaration or of the Securities. In the event
that any Event of Default with respect to the Preferred Securities is waived by
the Holders of Preferred Securities as provided in the Declaration, the Holders
of Common Securities agree that





    
<PAGE>   102
                                                                              13










such waiver shall also constitute the waiver of such Event of Default with
respect to the Common Securities for all purposes under the Declaration without
any further act, vote or consent of the Holders of the Common Securities.

                  A waiver of an Indenture Event of Default by the Property
Trustee at the direction of the Holders of the Preferred Securities will
constitute a waiver of the corresponding Event of Default under the Declaration
in respect of the Securities.

                  Any required approval of Holders of Common Securities may be
given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities of the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Common Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

                  No vote or consent of the Holders of Common Securities will be
required for the Trust to redeem and cancel Common Securities in accordance with
the Declaration.

                  6. Pro Rata Treatment. A reference in these terms of the
Common Securities to any payment, distribution or treatment as being "pro rata"
shall mean pro rata to each Holder of Securities according to the aggregate
liquidation amount of the Securities held by the relevant Holder in relation to
the aggregate liquidation amount of all Securities outstanding unless, in
relation to a payment, an Event of Default has occurred and is continuing, in
which case any funds available to make such payment shall be paid first to each
Holder of the Preferred Securities pro rata according to the aggregate
liquidation amount of Preferred Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Preferred Securities outstanding, and
only after satisfaction of all amounts owed to the Holders of the Preferred
Securities, to each Holder of Common Securities pro rata according to the
aggregate





    
<PAGE>   103
                                                                              14










liquidation amount of Common Securities held by the relevant Holder relative to
the aggregate liquidation amount of all Common Securities outstanding.

                  7. Ranking. The Common Securities rank pari passu and payment
thereon will be made pro rata with the Preferred Securities except that where an
Event of Default occurs and is continuing, the rights of Holders of Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption or otherwise are subordinate to the rights of Holders of the
Preferred Securities.

                  8. Mergers, Consolidations or Amalgamations. The Trust may not
consolidate, amalgamate, merge with or into, or be replaced by, or sell,
transfer or lease all or substantially all its properties and assets to, any
Person.

                  9. Transfers, Exchanges, Method Payments. Payment of
Distributions and payments on redemption of the Common Securities will be
payable, the transfer of the Common Securities will be registrable, and Common
Securities will be exchangeable for Common Securities of other denominations of
a like aggregate liquidation amount, at the principal corporate trust office of
the Property Trustee in The City of New York; provided that payment of
Distributions may be made at the option of the Regular Trustees on behalf of the
Trust by check mailed to the address of the Persons entitled thereto and that
the payment on redemption of any Common Security will be made only upon
surrender of such Common Security to the Property Trustee. Notwithstanding the
foregoing, transfers of Common Securities are subject to conditions set forth in
Section 9.01(c) of the Declaration.

                  10. Acceptance of Indenture. Each Holder of Common Securities,
by the acceptance thereof, agrees to the provisions of the Indenture and the
Debentures, including the subordination provisions thereof.

                  11. No Preemptive Rights. The Holders of Common Securities
shall have no preemptive rights to subscribe to any additional Common Securities
or Preferred Securities.

                  12. Miscellaneous. These terms shall constitute a part of the
Declaration. The Trust will provide a copy of the Declaration and the Indenture
to a Holder without charge on written request to the Trust at its principal
place of business.

                                    ARTICLE I

                         General Terms and Conditions of
                          the Series      % Debentures

                  SECTION 1.01. There shall be and is hereby authorized a series
of Debentures designated the "     % Junior Subordinated Debentures Due 20[ ]",
limited in aggregate principal amount to $   (except as provided in this Section
1.01 and Section 6.01). Upon exercise of the overallotment option set forth in
the Underwriting Agreement (as defined in the Declaration of Trust), additional
Series % Debentures in the aggregate principal amount of up to $    may be 
executed by the Company and delivered to the Trustee for authentication, and the
Trustee shall thereupon authenticate and deliver said Series    % Debentures to

evidence satisfactory to the Trustee that the overallotment option has been 
exercised. The Series    % Debentures shall mature and the principal thereof 
shall be due and payable, together with all accrued and unpaid interest thereon,
including Compounded Interest (as defined below) on        , 20[  ].

                  SECTION 1.02. (a) Except as provided in Section 1.02(b), the
Series   % Debentures shall be issued in definitive registered certificated form
without interest coupons. Principal and interest on the Series   % Debentures
issued in certificated form will be payable, the transfer of such Series      %

for Series    % Debentures bearing identical terms and provisions at the office 
or agency of the Company in the Borough of Manhattan, The City and State of New
York; provided, however, that payment of interest may be made at the option of
the Company by check mailed to the registered holder at such address as shall

to the Series   % Debentures will only be made upon surrender of the Series    %
Debentures to the Trustee. Notwithstanding the foregoing, so long as the
Property

                                                                              4

Trustee is the record holder of Series    % Debentures, the payment of the
principal of, and interest (including Compounded Interest, if any) on, the
Series   % Debentures held of record by the Property Trustee will be made by the
Company in immediately available funds on the payment date therefor to the
Property Account (as defined in the Declaration of Trust) established and
maintained by the Property Trustee pursuant to the Declaration of Trust.

                  (b)  In connection with a Dissolution Event:

                  (i) Series   % Debentures in certificated form in an aggregate
         principal amount equal to the aggregate liquidation amount of all
         Preferred Securities held in book-entry form may be presented to the
         Trustee by the Property Trustee in exchange for a Global Debenture
         representing such Series   % Debentures, such Global Debenture to be
         registered in the name of the Depositary, or its nominee, and delivered
         by the Trustee to the Depositary pursuant to the instructions of the
         Regular Trustees (as defined in the Declaration of Trust) for crediting
         to the accounts of the Depositary's participants. The Company, upon any
         such presentation, shall execute a Global Debenture representing the
         Series   % Debentures in such aggregate principal amount and deliver 
         the same to the Trustee for authentication and delivery in accordance 
         with the Indenture and this [ ] Supplemental Indenture. Payments on the
         Series   % Debentures issued as a Global Debenture will be made to the
         Depositary.

                  (ii) If any Preferred Securities are held in non book-entry
         certificated form ("Non Book-Entry Preferred Securities"), Series   %
         Debentures in certificated form in an aggregate principal amount equal
         to the aggregate liquidation amount of any such Non Book-Entry
         Preferred Securities may be presented to the Trustee by the Property
         Trustee, and any Preferred Security Certificate (as defined in the
         Declaration of Trust) held in non book-entry certificated form will be
         deemed to represent beneficial interests in such Series   % Debentures
         presented to the Trustee by the Property Trustee having an aggregate
         principal amount equal to the aggregate liquidation amount of the Non
         Book-Entry Preferred Securities represented by such Preferred Security
         Certificate until such Preferred Security Certificate is presented to
         the Debenture Registrar for

                                                                             5

         registration of transfer or reissuance, at which time such Preferred
         Security Certificate will be canceled and a Series    % Debenture,
         registered in the name of the holder of the Preferred Security
         Certificate or the transferee of the holder of such Preferred Security
         Certificate, as the case may be, with an aggregate principal amount
         equal to the aggregate liquidation amount of the Preferred Security
         Certificate canceled will be executed by the Company and delivered to
         the Trustee for authentication and delivery in accordance with the
         Indenture and this [ ] Supplemental Indenture. On issue of such Series
             % Debentures, Series      % Debentures with an equivalent aggregate
         principal amount that were presented by the Property Trustee to the
         Trustee will be deemed to have been canceled.

                  SECTION 1.03.  Each Series      % Debenture will bear interest
at the rate of     % per annum from          , 199  until the principal thereof 
becomes due and payable, and on any overdue principal, and (to the extent that 
payment of such interest is enforceable under applicable law) on any overdue 
installment of interest at the same rate per annum, compounded monthly, payable 
(subject to the provisions of Article III) monthly in arrears on the first day 
of each month (each, an "Interest Payment Date", commencing on , 199 ), to the 
Person in whose name such Series   % Debenture (or one or more Predecessor 
Debentures) is registered at the close of business on the regular record date 
for such interest installment, which, except as set forth below, shall be, in 
respect of any Series    % Debentures represented by a Global Debenture or of 
which the Property Trustee is the registered holder, the close of business on 
the Business Day next preceding the Interest Payment Date with respect to such 
interest installment. Notwithstanding the foregoing sentence, if the Preferred 
Securities are no longer in book-entry only form or if, pursuant to the 
provisions of Section 2.11(c) of the Indenture, the Series   % Debentures are no
longer represented solely by a Global Debenture, the regular record date for 
such interest installment shall be the close of business on the fifteenth day of
the month immediately preceding the month in which the Interest Payment Date 
with respect to such interest installment occurs. Any installment of interest 
not punctually paid or duly provided for shall forthwith cease to be payable to
the registered holder of a Series   % Debenture on such regular record date and 
may be paid to the Person in whose name such
<PAGE>   7
                                                                             6

Series  % Debenture (or one or more Predecessor Debentures) is registered at the
close of business on a special record date to be fixed by the Trustee for the
payment of such defaulted interest, notice whereof to be given to the registered
holders of the Series   % Debentures not less than 10 days prior to such special
record date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Series   % Debentures may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture.

                  The amount of interest payable for any period will be computed
on the basis of a 360-day year of twelve 30-day months and for any period
shorter than a 30-day monthly interest period for which interest is computed,
the amount of interest payable will be computed on the basis of the actual
number of days elapsed. In the event that any date on which interest is payable
on the Series    % Debentures is not a Business Day, then payment of interest
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 is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.


                                   ARTICLE II

                        Optional Redemption of the Series
                                     % Debentures

                  SECTION 2.01. Except as provided in Section 2.02, Series    %
Debentures may not be redeemed by the Company prior to , 200 . Subject to the
terms of Article III of the Indenture, the Company shall have the right to
redeem the Series    % Debentures, in whole or in part, at any time or from time
to time, on or after             , 200 , at a redemption price equal to 100% of
the principal amount to be redeemed plus any accrued and unpaid interest 
thereon, including Compounded Interest, if any, to the date of such redemption 
(the "Optional Redemption Price"). Any redemption pursuant to this Section will
be made upon not less than 30 nor more than 60 days' notice.

                                                                             7

                  SECTION 2.02. If, at any time, a Tax Event (as defined below)
shall occur or be continuing and (i) the Regular Trustees and the Company shall
have received an opinion (a "Redemption Tax Opinion") of nationally recognized
independent tax counsel experienced in such matters that, as a result of such
Tax Event, there is more than an insubstantial risk that the Company would be
precluded from deducting the interest on the Series    % Debentures for United
States Federal income tax purposes even if the Series    % Debentures were
distributed to the holders of Preferred Securities and Common Securities in
liquidation of such holders' interest in the Trust as set forth in the
Declaration of Trust or (ii) the Regular Trustees shall have been informed by
such tax counsel that a No Recognition Opinion (as defined below) cannot be
delivered to the Trust, the Company shall have the right, upon not less than 30
or more than 60 days notice, to redeem the Series % Debentures in whole or in
part for cash at the Optional Redemption Price within 90 days following the
occurrence of such Tax Event; provided, however, that, if at the time there is
available to the Company or the Regular Trustees, on behalf of the Trust, the
opportunity to eliminate, within such 90-day period, such Tax Event by taking
some ministerial action ("Ministerial Action"), such as filing a form or making
an election, or pursuing some other similar reasonable measure that has no
adverse effect on the Trust, the Company or the holders of the Preferred
Securities, then the Company or the Regular Trustees, on behalf of the Trust,
will pursue such measure in lieu of redemption; and provided further that the
Company shall have no right to redeem the Series % Debentures while the Regular
Trustees, on behalf of the Trust, are pursuing any such Ministerial Action.

                  "Tax Event" means that the Regular Trustees and the Company
shall have obtained an opinion of nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after , 199 as a result of (a) 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, (b) any amendment to, or change in, an interpretation or application of
any such laws or regulations by any legislative body, court, governmental agency
or regulatory authority (including the enactment of any legislation and the
publication of any judicial decision or regulatory determination), (c) any
interpretation or
<PAGE>   9
                                                                            8

pronouncement that provides for a position with respect to such laws or
regulations that differs from the theretofore generally accepted position or (d)
any action taken by any governmental agency or regulatory authority, which
amendment or change is enacted, promulgated, issued or effective or which
interpretation or pronouncement is issued or announced or which action is taken,
in each case on or after , 199 , there is more than an insubstantial risk that
(i) the Trust, is, or will be within 90 days of the date thereof, subject to
United States Federal income tax with respect to income accrued or received on
the Series    % Debentures, (ii) the Trust is, or will be within 90 days of the
date thereof, subject to more than a de minimis amount of other taxes, duties or
other governmental charges or (iii) interest payable by the Company to the Trust
on the Series   % Debentures is not, or within 90 days of the date thereof will
not be, deductible by the Company for United States Federal income tax purposes.

                  "No Recognition Opinion" means an opinion of nationally
recognized independent tax counsel experienced in such matters, which opinion
may rely on any then applicable published revenue rulings of the Internal
Revenue Service, to the effect that the holders of the Preferred Securities will
not recognize any gain or loss for United States Federal income tax purposes as
a result of a dissolution of the Trust and distribution of the Series   %
Debentures as provided in the Declaration of Trust.

                  SECTION 2.03. If the Series   % Debentures are only partially
redeemed pursuant to this Article II, the Series   % Debentures will be redeemed
pro rata or by lot or by any other equitable method chosen by the Trustee;
provided that if, at the time of redemption, any Series   % Debentures are
represented by a Global Debenture, the Depositary shall determine by lot the
principal amount of such Series   % Debentures held by each Debentureholder to 
be redeemed in accordance with its customary procedures. Notwithstanding the
foregoing, if a partial redemption of the Series   % Debentures would result in
the delisting of the Preferred Securities by any national securities exchange on
which the Preferred Securities are then listed, the Company shall not be
permitted to effect such partial redemption and will only redeem the Series   %
Debentures in whole.

                      Extension of Interest Payment Period

                  SECTION 3.01. So long as the Company is not in default in the
payment of interest on the Series   % Debentures, the Company shall have the
right, at any time during the term of the Series   % Debentures, from time to 
time to extend the interest payment period of the Series   % Debentures for a 
period not exceeding 60 consecutive monthly interest periods (an "Extended 
Interest Payment Period"); provided, however, that at the end of any such 
period the Company shall pay all interest accrued and unpaid thereon (together 
with interest on such accrued and unpaid interest at the rate of % per annum, 
to the extent permitted by applicable law, compounded monthly ("Compounded
Interest")); and provided, further that an Extended Interest Payment Period may
not extend beyond the maturity of the Series [ ]% Debentures. During any 
Extended Interest Payment Period, the Company shall not declare or pay any 
dividends on, or redeem, purchase, acquire or make a distribution or liquidation
payment with respect to, any of its common stock or preferred stock or make any
payments on guarantees with respect thereto; provided, however, that the 
foregoing restrictions shall not apply to (i) dividends, redemptions, purchases,
acquisitions, distributions or payments made by the Company by way of issuance
of shares of its capital stock, (ii) payments of accrued dividends by the
Company upon the redemption, exchange or conversion of any preferred stock of
the Company as may be outstanding from time to time in accordance with the terms
of such preferred stock or (iii) cash payments made by the Company in lieu of
delivering fractional shares upon the redemption, exchange or conversion of any
preferred stock of the Company as may be outstanding from time to time in
accordance with the terms of such preferred stock. Prior to the termination of
any Extended Interest Payment Period, the Company may pay all or any portion of
the interest accrued on the Series   % Debentures on any Interest Payment Date 
to holders of record on the regular record date for such Interest Payment Date 
or from time to time further extend such Extended Interest Payment Period; 
provided that such Extended Interest Payment Period together with all such 
previous and further extensions thereof may not exceed 60 consecutive monthly 
interest periods. Upon the termination of any Extended Interest Payment Period 
and upon the payment of all accrued and unpaid interest then due, together with
Compounded Interest, the Company may select a new Extended

Interest Payment Period. No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof. At the end of any Extended
Interest Payment Period, the Company shall pay all interest accrued and unpaid
on the Series % Debentures, including any Compounded Interest, to the holders in
whose names the Series % Debentures are registered on the Debenture register on
the regular record date for the first Interest Payment Date occurring at or
after the end of the Extended Interest Payment Period.

                  SECTION 3.02. (a) So long as the Property Trustee is the sole
record holder of the Series   % Debentures, at the time the Company selects an
Extended Interest Payment Period, the Company shall give both the Property
Trustee and the Trustee written notice of its selection of such Extended
Interest Payment Period at least one Business Day prior to the earlier of (i)
the next succeeding date on which distributions on the Preferred Securities are
payable and (ii) the date on which the Trust is required to give notice of the
record or payment date for such distribution to the New York Stock Exchange (if
the Preferred Securities are then listed thereon) or other applicable
self-regulatory organization or to holders of the Preferred Securities, but in
any event not less than one Business Day prior to such record date. The Company
shall cause the Trust to give notice to the holders of the Preferred Securities
of the Company's selection of such Extended Interest Payment Period.

                  (b) If as a result of a Dissolution Event, Series % Debentures
have been distributed to holders of Preferred Securities and Common Securities,
at the time the Company selects an Extended Interest Payment Period, the Company
shall give the holders of the Series % Debentures and the Trustee written notice
of its selection of such Extended Interest Payment Period at least 10 Business
Days prior to the earlier of (i) the next succeeding Interest Payment Date or
(ii) the date the Company is required to give notice of the record or payment
date for such interest payment to the New York Stock Exchange (if the Series   %
Debentures are then listed thereon) or other applicable self-regulatory
organization or to holders of the Series % Debentures.

                  SECTION 3.03. The month in which any notice is given pursuant
to Section 3.02 shall be counted as one of the 60 consecutive monthly interest
periods permitted in the

                Covenants Applicable to Series       % Debentures

                  SECTION 4.01. So long as any Preferred Securities remain
outstanding, the Company will not declare or pay any dividends on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred stock or make any payments on guarantees
with respect thereto if at such time (i) the Company shall be in default with
respect to its Guarantee Payments (as defined in the Guarantee Agreement) or
other payment obligations under the Guarantee Agreement or (ii) there shall have
occurred any Event of Default under the Indenture with respect to the Series %
Debentures; provided, however, that the foregoing restrictions shall not apply
to (i) dividends, redemptions, purchases, acquisitions, distributions or
payments made by the Company by way of issuance of shares of its capital stock,
(ii) payments of accrued dividends by the Company upon the redemption, exchange
or conversion of any preferred stock of the Company as may be outstanding from

redemption, exchange or conversion of any preferred stock of the Company as may
be outstanding from time to time in accordance with the terms of such preferred
stock.

                  SECTION 4.02. In connection with the distribution of the
Series % Debentures to the holders of the Preferred Securities upon a
Dissolution Event, the Company will use its best efforts to list such Series   %
Debentures on the New York Stock Exchange or on such other exchange as the
Preferred Securities are then listed.

                  SECTION 4.03. The Company covenants and agrees for the benefit
of the holders of the Preferred Securities to comply fully with all its
obligations and agreements under the Declaration of Trust, including, without
limitation, its obligations under Article IV thereof.

                  Paine Webber Group Inc., a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
             , or registered assigns, the principal sum of Dollars        on
              , 20[ ] and to pay interest on said principal sum from          ,
199  or from the most recent interest payment date (each such date, an 
"Interest Payment Date") to which interest has been paid or duly provided for, 
monthly (subject to deferral as set forth herein) in arrears on the first day 
of each month commencing             , 199 , at the rate of     % per annum,
until the principal hereof shall have become due and payable, and on any overdue
principal and (to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the same rate per
annum, compounded monthly. The amount of interest payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months and for any
period shorter than a 30-day monthly interest period for which interest is
computed, the amount of interest payable will be computed on the basis of the
actual number of days elapsed. In the event that any date on which interest is
payable on this Debenture is not a Business Day, then payment of interest
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 is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date. The interest installment

will, as provided in the Indenture referred to on the reverse side hereof, be
paid to the Person in whose name this Debenture (or one or more Predecessor
Debentures) is registered at the close of business on the regular record date
for such interest installment, which shall be the close of business on the
Business Day next preceding such Interest Payment Date; provided, however, that
if the Preferred Securities are no longer in book-entry only form or if,
pursuant to the provisions of Section 2.11(c) of the Indenture, the Series
   % Debentures are no longer represented solely by a Global Debenture, the
regular record date shall be the close of business on the fifteenth day of the
month immediately preceding the month in which such Interest Payment Date
occurs. Any such interest installment not punctually paid or duly provided for
shall forthwith cease to be payable to the registered holder of this Debenture
on such regular record date, and may be paid to the Person in whose name this
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on a special record date to be fixed by the Trustee for the payment of
such defaulted interest, notice whereof to be given to the registered holders of
this series of Debentures not less than 10 days prior to such special record
date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Series    %
Debentures may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. The principal of, and the
interest on, this Debenture shall be payable at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City and
State of New York in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the
Company by check mailed to the registered holder at such address as shall appear
in the Debenture Register and that the payment of principal will only be made
upon the surrender of this Debenture to the Trustee. Notwithstanding the
foregoing, so long as the record holder of this Debenture is the Property
Trustee (as defined in the Indenture), the payment of the principal of, and
interest on, this Debenture will be made to such account of the Property Trustee
as may be designated by the Property Trustee.

                  The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto. Each holder of
this Debenture, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact, for
any and all such purposes. Each Debentureholder, by his acceptance hereof hereby
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder upon
such provisions.

executed by the Trustee referred to on the reverse side hereof, this Debenture
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

side hereof and such continued provisions shall for all purposes have the same
effect as though fully set forth at this place.

                         (FORM OF REVERSE OF DEBENTURE)

                  This Debenture is one of a duly authorized series of
Debentures of the Company (herein sometimes referred to as the "Debentures"),
all issued or to be issued in one or more series under and pursuant to an
Indenture dated as of November , 1996 duly executed and delivered between the
Company and The Chase Manhattan Bank, a New York banking corporation, as Trustee
(herein referred to as the "Trustee"), as supplemented by the [ ] Supplemental
Indenture dated as of , 199 between the Company and the Trustee (said Indenture
as so supplemented being hereinafter referred to as the "Indenture"), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the
Debentures, and, to the extent specifically set forth in the Indenture, the
holders of Senior Indebtedness and Preferred Securities. By the terms of the
Indenture, the Debentures are issuable in series which may vary as to amount,
date of maturity, rate of interest and in other respects as in the Indenture
provided. This series of Debentures is designated the   % Junior Subordinated
Debentures due 20 (the "Series   %
<PAGE>   18
                                                                             17
 
Debentures") and is limited in aggregate principal amount as specified in said 
[ ] Supplemental Indenture.

                  Except as provided in the next paragraph, the Series   %
Debentures may not be redeemed by the Company prior to                   , 20 .
The Company shall have the right to redeem the Series   % Debentures, in whole
or in part, at any time or from time to time on or after                  , 20
(an "Optional Redemption"), at a redemption price equal to 100% of the principal
amount to be redeemed plus any accrued and unpaid interest, including any
Compounded Interest, thereon to the date of such redemption. Any redemption
pursuant to this paragraph will be made upon not less than 30 nor more 60 days
notice. If the Debentures are only partially redeemed by the Company pursuant to
an Optional Redemption, the Series  % Debentures will be redeemed pro rata or by
lot or by any other equitable method chosen by the Trustee; provided that if, at
the time of redemption, any Series  % Debentures are represented by a Global
Debenture, the Depository shall determine the principal amount of such Series
% Debentures held by each holder of Series    % Debentures to be redeemed in
accordance with its customary procedures.

                  If, at any time, a Tax Event (as defined below) shall occur or
be continuing and (i) the Regular Trustees and the Company shall have received
an opinion (a "Redemption Tax Opinion") of nationally recognized independent tax
counsel experienced in such matters that, as a result of such Tax Event, there
is more than an insubstantial risk that the Company would be precluded from
deducting the interest on the Series   % Debentures for United States Federal
income tax purposes even if the Series
     % Debentures were distributed to the holders of Preferred Securities and
Common Securities in liquidation of such holders' interest in the Trust as set
forth in the Declaration of Trust or (ii) the Regular Trustees shall have been
informed by such tax counsel that a No Recognition Opinion (as defined below)
cannot be delivered to the Trust, the Company shall have the right, upon not
less than 30 nor more than 60 days notice, to redeem the Series  % Debentures in
whole or in part for cash at the Optional Redemption Price within 90 days
following the occurrence of such Tax Event; provided, however, that, if at the
time there is available to the Company or the Regular Trustees, on behalf of the
Trust, the opportunity to eliminate, within such 90-day period, the Tax Event by
taking some ministerial action ("Ministerial Action"), such as filing a form or
<PAGE>   19
                                                                             18
 
making an election, or pursuing some other similar reasonable measure, which has
no adverse effect on the Trust, the Company or the holders of the Preferred
Securities, the Company or the Regular Trustees, on behalf of the Trust, will
pursue such measure in lieu of redemption; and provided further that the Company
shall have no right to redeem the Series    % Debentures while the Regular
Trustees, on behalf of the Trust, are pursuing any such Ministerial Action.

                  "Tax Event" means that the Regular Trustees and the Company
shall have obtained an opinion of nationally recognized independent tax counsel
experienced in such matters (a "Dissolution Tax Opinion") to the effect that on
or after             , 199 , as a result of (a) any amendment to, or change (or
announced prospective change) in, the laws (or any regulations thereunder) of
the United States or any political subdivision or taxing authority thereof or
therein, (b) any amendment to, or change in, an interpretation or application of
any such laws or regulations by any legislative body, court, governmental agency
or regulatory authority (including the enactment of any legislation and the
publication of any judicial decision or regulatory determination), (c) any
interpretation or pronouncement that provides for a position with respect to
such laws or regulations that differs from the theretofore generally accepted
position or (d) any action taken by any governmental agency or regulatory
authority, which amendment or change is enacted, promulgated, issued or
effective or which interpretation or pronouncement is issued or announced or
which action is taken, in each case on or after                  , 199 , there
is more than an insubstantial risk that (i) the Trust is, or will be within 90
days of the date thereof, subject to United States Federal income tax with
respect to income accrued or received on the Series   % Debentures, (ii) the
Trust is, or will be within 90 days of the date thereof, subject to more than a
de minimis amount of other taxes, duties or other governmental charges or (iii)
interest payable by the Company to the Trust on the Series   % Debentures is
not, or within 90 days of the date thereof will not be, deductible by the
Company for United States Federal income tax purposes.

                  "No Recognition Opinion" means an opinion of nationally
recognized independent tax counsel experienced in such matters, which opinion
may rely on any then applicable published revenue rulings of the Internal
Revenue Service, to the effect that the holders of the Preferred Securities
<PAGE>   20
                                                                             19
 
will not recognize any gain or loss for United States Federal income tax
purposes as a result of a dissolution of the Trust and distribution of the
Series    % Debentures as provided in the Declaration of Trust.

                  If the Debentures are only partially redeemed by the Company
pursuant to an Optional Redemption or as a result of a Tax Event as described
above, the Debentures will be redeemed pro rata or by lot or by any other
equitable method chosen by the Trustee. Notwithstanding the foregoing, if a
partial redemption of the Series   % Debentures would result in the delisting of
the Preferred Securities by any national securities exchange on which the
Preferred Securities are then listed, the Company shall not be permitted to
effect such partial redemption and will only redeem the Series   % Debentures in
whole.

                  In the event of redemption of this Debenture in part only, a
new Series   % Debenture or Debentures will be issued for the unredeemed portion
hereof in the name of the holder hereof upon the cancelation of this Debenture.

                  In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Series   %
Debentures may be declared, and upon such declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.

                  The Indenture contains provisions for defeasance at any time
of the entire indebtedness of the Series   % Debentures upon compliance by the
Company with certain conditions set forth therein.

                  The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the time
outstanding, as defined in Section 8.04 of the Indenture, (and, in the case of
any series of Debentures held as trust assets of a PWG Capital Trust and with
respect to which a Security Exchange has not theretofore occurred, such consent
of holders of the Preferred Securities and the Common Securities of such PWG
Capital Trust as may be required under the Declaration of Trust of such PWG
Capital Trust), to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any
<PAGE>   21
                                                                             20
 
supplemental indenture or of modifying in any manner the rights of the holders
of any series of Debentures; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Debentures of any series,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Debenture so affected or (ii)
reduce the aforesaid percentage of Debentures, the holders of which are required
to consent to any such supplemental indenture, without the consent of the
holders of each Debenture (and, in the case of any series of Debentures held as
trust assets of a PWG Capital Trust and with respect to which a Security
Exchange has not theretofore occurred, such consent of the holders of the
Preferred Securities and the Common Securities of such PWG Capital Trust as may
be required under the Declaration of Trust of such PWG Capital Trust) then
outstanding and affected thereby. The Indenture also contains provisions
permitting the Holders of a majority in aggregate principal amount of the
Debentures of a series at the time outstanding affected thereby (subject, in the
case of any series of Debentures held as trust assets of a PWG Capital Trust and
with respect to which a Securities Exchange has not theretofore occurred, to
such consent of holders of Preferred Securities and Common Securities of such
PWG Capital Trust as may be required under the Declaration of Trust of such PWG
Capital Trust), on behalf of the holders of the Debentures of such series, to
waive any past default in the performance of any of the covenants contained in
the Indenture, or established pursuant to the Indenture with respect to such
series and its consequences, except a default in the payment of the principal
of, or premium, if any, or interest on, any of the Debentures of such series.
Any such consent or waiver by the registered holder of this Debenture (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
holder and upon all future holders and owners of this Debenture and of any
Debenture issued in exchange herefor or in place hereof (whether by registration
of transfer or otherwise), irrespective of whether or not any notation of such
consent or waiver is made upon this Debenture.

                  Subject to Section 13.11 of the Indenture, no reference herein
to the Indenture (other than such Section) and no provision of this Debenture or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and

                                                                              21
 
premium, if any, and interest on this Debenture at the time and place, at the
rate and in the money herein prescribed.

                  So long as the Company is not in default in the payment of
interest on the Series % Debentures, the Company shall have the right, at any
time during the term of the Series % Debentures, from time to time to extend the
interest payment period of the Series % Debentures for a period not exceeding 60
consecutive monthly interest periods (an "Extended Interest Payment Period");
provided, however, that at the end of any such period the Company shall pay all
interest accrued and unpaid thereon, together with any Compounded Interest; and
provided, further that an Extended Interest Payment Period may not extend the
maturity of the Series % Debentures. During any Extended Interest Payment
Period, the Company shall not declare or pay any dividends on, or redeem,
purchase, acquire or make a distribution or liquidation payment with respect to,
any of its common stock or preferred stock, or make any payments on guarantees
with respect thereto; provided, however, that the foregoing restrictions shall
not apply to (i) dividends, redemptions, purchases, acquisitions, distributions
or payments made by the Company by way of issuance of shares of its capital
stock, (ii) payments of accrued dividends by the Company upon the redemption,
exchange or conversion of any preferred stock of the Company as may be
outstanding from time to time in accordance with the terms of such preferred
stock or (iii) cash payments made by the Company in lieu of delivering
fractional shares upon the redemption, exchange or conversion of any preferred
stock of the Company as may be outstanding from time to time in accordance with
the terms of such preferred stock. Prior to the termination of any Extended
Interest Payment Period, the Company may pay all or any portion of the interest
accrued on the Series % Debentures on any Interest Payment Date to holders of
record on the regular record date for such Interest Payment Date or from time to
time further extend such Extended Interest Payment Period; provided that such
Extended Interest Payment Period together with all such previous and further
extensions thereof may not exceed 60 consecutive monthly interest periods. Upon
the termination of any Extended Interest Payment Period and upon the payment of
all accrued and unpaid interest then due, together with Compounded Interest, the
Company may select a new Extended Interest Payment Period. No interest shall be
due and payable during an Extended Interest Payment Period, except at the end
thereof. At the end of any Extended Interest Payment Period, the Company shall
pay all interest

                                                                           22

accrued and unpaid on the Series      % Debentures, including any Compounded
Interest which shall be payable to the holders in whose names the Series     %
Debentures are registered on the Debenture Register on the regular record date
for the first Interest Payment Date occurring on or after the end of the
Extended Interest Payment Period.

                  As provided in the Indenture and subject to certain
limitations therein set forth, this Debenture is transferable by the registered
holder hereof on the Debenture Register of the Company, upon surrender of this
Debenture for registration of transfer at the office or agency of the Company
designated for such purpose in the Borough of Manhattan, The City and State of
New York, accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Debenture Registrar duly executed by the
registered holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Series      % Debentures of authorized denominations
and for the same aggregate principal amount will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in relation thereto.

                  Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and any Debenture
Registrar may deem and treat the registered holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and notwithstanding any
notice of ownership or writing hereon made by anyone other than the Debenture
Registrar) for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any Debenture Registrar
shall be affected by any notice to the contrary.

                  No recourse under or upon any obligation, covenant or
agreement of the Indenture, or of this Debenture, or for any claim based thereon
or hereon, or otherwise in respect thereof or hereof shall be had against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, either
directly or through the Company or any such predecessor or successor
corporation, whether by virtue of any constitution, statute or rule of law, or

                  SECTION 3.01. Powers and Duties of the Guarantee Trustee. (a)
This Guarantee Agreement shall be held by the Guarantee Trustee in trust for the
benefit of the Holders. The Guarantee Trustee shall not transfer its right,
title and interest in this Guarantee Agreement to any Person except a Successor
Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its
appointment to act as Guarantee Trustee or to a Holder exercising his or her
rights pursuant to Section 5.04. The right, title and interest of the Guarantee

Such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered.

                  (b) If an Event of Default occurs and is continuing, the

provided that, the Guarantee Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Guarantee
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders. The Guarantee Trustee shall not be deemed to have
knowledge of any Event of Default except any Event of Default as to which the

with the administration of this Guarantee Agreement shall have obtained written
notice.

                  (e) The Guarantee Trustee shall not resign as a Trustee unless
a Successor Guarantee Trustee has been appointed and accepted that appointment

Trustee. (a) The Guarantee Trustee, before the occurrence of an Event of Default
and after the curing or waiving of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.06(a)),
the Guarantee Trustee shall exercise such of the rights and powers vested in it
by this Guarantee Agreement, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

                  (b) No provision of this Guarantee Agreement shall be
construed to relieve the Guarantee Trustee from liability for its own negligent
action, its own negligent failure to act or its own wilful misconduct, except
that:

                  (i) prior to the occurrence of an Event of Default
    and after the curing or waiving of all Events of Default
    that may have occurred;

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

                           (B) in the absence of bad faith on the part of the
                  Guarantee Trustee, the Guarantee Trustee may conclusively
                  rely, as to the truth of the statements and the correctness of
                  the opinions expressed therein, upon any certificates or


<PAGE>   13
                                                                              10










                  opinions furnished to the Guarantee Trustee and conforming to
                  the requirements of this Guarantee Agreement; but in the case
                  of any such certificates or opinions that by any provision
                  hereof are specifically required to be furnished to the
                  Guarantee Trustee, the Guarantee Trustee shall be under a duty
                  to examine the same to determine whether or not they conform
                  to the requirements of this Guarantee Agreement;

                (ii) the Guarantee Trustee shall not be liable for any error of
    judgment made in good faith by a Responsible Officer of the Guarantee
    Trustee, unless it shall be proved that the Guarantee Trustee was negligent
    in ascertaining the pertinent facts;

              (iii) the Guarantee Trustee shall not be liable with respect to
    any action taken or omitted to be taken by it in good faith in accordance
    with the direction of the Holders as provided herein relating to the time,
    method and place of conducting any proceeding for any remedy available to
    the Guarantee Trustee, or exercising any trust or power conferred upon the
    Guarantee Trustee under this Guarantee Agreement; and

                (iv) no provision of this Guarantee Agreement shall require the
    Guarantee Trustee to expend or risk its own funds or otherwise incur
    personal financial liability in the performance of any of its duties or in
    the exercise of any of its rights or powers, if it shall have reasonable
    ground for believing that the repayment of such funds or liability is not
    reasonably assured to it under the terms of this Guarantee Agreement or
    adequate indemnity against such risk or liability is not reasonably assured
    to it.

                  (c)  Subject to the provisions of Section 3.02(a) and (b):

                  (i) whenever in the administration of this Guarantee
    Agreement, the Guarantee Trustee shall deem it desirable that a matter be
    proved or established prior to taking, suffering or omitting any action
    hereunder, the Guarantee Trustee (unless other evidence is herein
    specifically prescribed) may, in the absence of bad faith on its part and,
    if the Trust is excluded from the definition of Investment Company solely by
    reason of Rule 3a-7 under the Investment Company Act ("Rule 3a-7"),

    subject to the requirements of Rule 3a-7, request and rely upon a
    certificate, which shall comply with the provisions of Section 314(e) of the

                (ii) the Guarantee Trustee (A) may consult with counsel (which
    may be counsel to the Guarantor or any of its Affiliates and may include any
    of its employees) selected by it in good faith and with due care and the
    written advice or opinion of such counsel with respect to legal matters
    shall be full and complete authorization and protection in respect of any
    action taken, suffered or omitted by it hereunder in good faith and in
    reliance thereon and in accordance with such advice and opinion and (B)
    shall have the right at any time to seek instructions concerning the
    administration of this Guarantee Agreement from any court of competent
    jurisdiction;

              (iii) the Guarantee Trustee may execute any of the trusts or
    powers hereunder or perform any duties hereunder either directly or by or

    responsible for any misconduct or negligence on the part of any agent or
    attorney appointed by it in good faith and with due care;

                (iv) the Guarantee Trustee shall be under no obligation to
    exercise any of the rights or powers vested in it by this Guarantee
    Agreement at the request or direction of any Holders, unless such Holders
    shall have offered to the Guarantee Trustee reasonable security and
    indemnity against the costs, expenses (including attorneys' fees and
    expenses) and liabilities that might be incurred by it in complying with
    such request or direction; provided that nothing contained in this clause
    (iv) shall relieve the Guarantee Trustee of the obligation, upon the
    occurrence of an Event of Default (which has not been cured or waived) to
    exercise such of the rights and powers vested in it by this Guarantee
    Agreement, and to use the same degree of care and skill in such exercise, as
    a prudent person would exercise or use under the circumstances in the
    conduct of his or her own affairs; and

                  (v) any action taken by the Guarantee Trustee or its agents
    hereunder shall bind the Holders and the signature of the Guarantee Trustee
    or its agents alone

    party shall be required to inquire as to the authority of the Guarantee

    Preferred Securities;

                  (f) the settlement or compromise of any obligation guaranteed
    hereby or hereby incurred; or

                  (g) any other circumstances whatsoever that might otherwise
    constitute a legal or equitable discharge or defense of a guarantor, it
    being the intent of this Section 5.03 that the obligations of the Guarantor
    hereunder shall be absolute and unconditional under any and all
    circumstances.

                  There shall be no obligation of the Holders to give notice to,
or obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

                  SECTION 5.04. Enforcement of Guarantee. The Guarantor and the
Guarantee Trustee expressly acknowledge that (i) this Guarantee Agreement will
be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) Holders representing not less than a
Majority in liquidation amount of the Preferred Securities have the right to
direct the time, method and place of conducting any proceeding for any remedy
available in respect of this Guarantee Agreement,

                                                                              16










including the giving of directions to the Guarantee Trustee, or exercising any
trust or other power conferred upon the Guarantee Trustee under this Guarantee
Agreement, and (iv) if the Guarantee Trustee fails to enforce this Guarantee
Agreement, any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee Agreement, without first
instituting a legal proceeding against the Issuer, the Guarantee Trustee or any
other Person. Notwithstanding the foregoing, if the Guarantor has failed to make
a Guarantee Payment, a Holder of Preferred Securities may directly institute a
proceeding against the Guarantor for enforcement of such Holder's right to
receive payment under the Guarantee. The Guarantor waives any right or remedy to
require that any action be brought first against the Issuer or any other person
or entity before proceeding directly against the Guarantor.

                  SECTION 5.05. Guarantee of Payment. This Guarantee Agreement
creates a guarantee of payment and not merely of collection. This Guarantee
Agreement will not be discharged except by payment of the Guarantee Payments in
full (without duplication of amounts theretofore paid by the Issuer).

                  SECTION 5.06. Subrogation. The Guarantor shall be subrogated
to all rights, if any, of the Holders against the Issuer in respect of any
amounts paid to the Holders by the Guarantor under this Guarantee Agreement;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any rights
which it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Guarantee
Agreement, if, at the time of any such payment, any amounts are due and unpaid
under this Guarantee Agreement. If any amount shall be paid to the Guarantor in
violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

                  SECTION 5.07. Independent Obligations. The Guarantor
acknowledges that its obligations hereunder are independent of the obligations
of the Issuer with respect to the Preferred Securities and that the Guarantor
shall be liable as principal and as debtor hereunder to make Guarantee Payments
pursuant to the terms of this Guarantee Agreement notwithstanding the occurrence
of any event

referred to in subsections (a) through (g), inclusive, of Section 5.03.


                                   ARTICLE VI

                    Limitation of Transactions; Subordination

                  SECTION 6.01. Limitation of Transactions. So long as any
Preferred Securities remain outstanding, the Guarantor will not declare or pay
any dividends on, or redeem, purchase, acquire or make a distribution or
liquidation payment with respect to, any of its common stock or preferred stock
or make any guarantee payment with respect thereto if at such time (i) the
Guarantor shall be in default with respect to its Guarantee Payments or other
payment obligations hereunder, (ii) there shall have occurred any Event of
Default (as defined in the Declaration) or (iii) the Guarantor shall have given
notice of its selection of an Extension Period (as defined in the Indenture) and
such period, or any extension thereof, is continuing; provided, however, that
the foregoing restrictions will not apply to (i) dividends, redemptions,
purchases, acquisitions, distributions or payments made by the Guarantor by way
of issuance of shares of its capital stock, (ii) payments of accrued dividends
by the Guarantor upon the redemption, exchange or conversion of any preferred
stock of the Guarantor as may be outstanding from time to time in accordance
with the terms of such preferred stock or (iii) cash payments made by the
Guarantor in lieu of delivering fractional shares upon the redemption, exchange
or conversion of any preferred stock of the Guarantor as may be outstanding from
time to time in accordance with the terms of such preferred stock. In addition,
so long as any Preferred Securities remain outstanding, the Guarantor (i) will
remain the sole direct or indirect owner of all the outstanding Common
Securities and shall not cause or permit the Common Securities to be transferred
except to the extent such transfer is permitted under Section 9.01(c) of the
Declaration, provided that any permitted successor of the Guarantor under the
Indenture may succeed to the Guarantor's ownership of the Common Securities; and
(ii) will use reasonable efforts to cause the Issuer to continue to be treated
as a grantor trust for United States Federal income tax purposes, except in
connection with a distribution of Debentures as provided in the Declaration.

                  SECTION 6.02. Subordination. This Guarantee Agreement will
constitute an unsecured obligation of the Guarantor and will rank (i)
subordinate and junior in right of payment to all other indebtedness,
liabilities and obligations of the Guarantor and any guarantees, endorsements or
other contingent obligations of the Guarantor in respect of such indebtedness,
liabilities or obligations, including the Debentures, except those made pari
passu or subordinate by their terms, and (ii) senior to all capital stock now or
hereafter issued by the Guarantor and to any guarantee now or hereafter entered
into by the Guarantor in respect of any of its capital stock. The Guarantor's
obligations under this Guarantee Agreement will rank pari passu with respect to
obligations under other guarantee agreements which it may enter into from time
to time to the extent that such agreements shall be entered into in
substantially the form hereof and provide for comparable guarantees by the
Guarantor of payment on preferred securities issued by other statutory business
trusts of which the Guarantor holds the common securities.


                                   ARTICLE VII

                                   Termination

                  This Guarantee Agreement shall terminate and be of no further
force and effect upon full payment of the Redemption Price of all Preferred
Securities, or upon the distribution of Debentures to Holders in exchange for
all the Preferred Securities, or upon full payment of the amounts payable in
accordance with the Declaration upon liquidation of the Issuer. Notwithstanding
the foregoing, this Guarantee Agreement will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder must restore payment
of any sums paid with respect to the Preferred Securities or this Guarantee
Agreement.


                                  ARTICLE VIII

                    Limitation of Liability; Indemnification

                  SECTION 8.01. Exculpation. (a) No Indemnified Person shall be
liable, responsible or accountable in damages or otherwise to the Guarantor or
any Covered Person for any loss, damage or claim incurred by reason of any act
or omission performed or omitted by such Indemnified Person

<PAGE>   22
                                                                              19










in good faith and in a manner such Indemnified Person reasonably believed to be
within the scope of the authority conferred on such Indemnified Person by this
Guarantee Agreement or by law, except that an Indemnified Person shall be liable
for any such loss, damage or claim incurred by reason of such Indemnified
Person's negligence or wilful misconduct with respect to such acts or omissions.

                  (b) An Indemnified Person shall be fully protected in relying
in good faith upon the records of the Guarantor and upon such information,
opinions, reports or statements presented to the Guarantor by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Guarantor, including information,
opinions, reports or statements as to the value and amount of assets,
liabilities, profits, losses or any other facts pertinent to the existence and
amounts of assets from which Distributions to Holders might properly be paid.

                  SECTION 8.02. Indemnification. (a) To the fullest extent
permitted by applicable law, the Guarantor shall indemnify and hold harmless
each Indemnified Person from and against any loss, damage or claim incurred by
such Indemnified Person by reason of any act or omission performed or omitted by
such Indemnified Person in good faith and in a manner such Indemnified Person
reasonably believed to be within the scope of authority conferred on such
Indemnified Person by this Guarantee Agreement, except that no Indemnified
Person shall be entitled to be indemnified in respect of any loss, damage or
claim incurred by such Indemnified Person by reason of negligence or wilful
misconduct with respect to such acts or omissions.

                  (b) To the fullest extent permitted by applicable law,
expenses (including legal fees) incurred by an Indemnified Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by the Guarantor prior to the final disposition of such claim, demand,
action, suit or proceeding upon receipt by the Guarantor of an undertaking by or
on behalf of the Indemnified Person to repay such amount if it shall be
determined that the Indemnified Person is not entitled to be indemnified as
authorized in Section 8.02(a).

                  SECTION 9.01. Successors and Assigns. All guarantees and
agreements contained in this Guarantee Agreement shall bind the successors,
assignees, receivers, trustees and representatives of the Guarantor and shall
inure to the benefit of the Holders of the Preferred Securities then
outstanding. Except in connection with a consolidation, merger or conveyance,
transfer or lease of assets involving the Guarantor that is permitted under

                           Preferred Trust Securities

Ladies and Gentlemen:

              We have acted as counsel for Paine Webber Group Inc., a Delaware
corporation (the "Company"), and PWG Capital Trusts I, II, III and IV, each a
business trust created under the Delaware Business Trust Act of the State of
Delaware (each, a "Trust"), in connection with the proposed issuance by each
Trust of its Preferred Trust Securities ("Preferred Securities") in each case
pursuant to the terms of its Declaration of Trust, dated as of October 7, 1996
(the "Declaration" of such Trust), as amended and restated by an Amended and
Restated Declaration of Trust (as so amended and restated, the "Amended
Declaration" of such Trust), among the Company, as sponsor, the trustees named
therein and the holders from time to time of undivided beneficial interests in
the assets of such Trust, to be dated as of the date of the initial issuance of
Preferred Securities by such Trust. Pursuant to a Guarantee Agreement (the
"Guarantee Agreement" of such Trust), between the Company and The Chase
Manhattan Bank, as Trustee (the "Guarantee Trustee"), to be dated as of the date
of the initial issuance of Preferred Securities by such Trust, the Preferred
Securities of each Trust will be guaranteed (the "Guarantees") by the Company
with respect to distributions and payments upon liquidation, redemption or
otherwise, as
<PAGE>   2
                                                                               2


and to the extent set forth in such Guarantee Agreement. The assets of each
Trust will consist of a series of Junior Subordinated Debt Securities (the
"Junior Subordinated Debentures") of the Company which will be issued under an
Indenture (the "Base Indenture"), to be entered into by the Company and The
Chase Manhattan Bank, as Trustee (the "Indenture Trustee"), as supplemented by a
Supplemental Indenture with respect to such series to be entered into by the
Company and the Indenture Trustee (the "Supplemental Indenture" of such Trust
and, together with the Base Indenture, the "Indenture" of such Trust) as of the
date of the initial issuance of Preferred Securities by such Trust.

              In that connection, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of such documents,
corporate records and other instruments as we have deemed necessary or
appropriate for the purposes of this opinion, including: (a) the Restated
Certificate of Incorporation of the Company, as amended; (b) the By-laws of the
Company; (c) the Registration Statement on Form S-3 (Registration Nos.
333-13831, 333- 13831-01, 333-13831-02, 333-13831-03 and 333-13831-04) filed
with the Securities and Exchange Commission (the "Commission") on October 10,
1996, as amended by Amendment No. 1 thereto filed with the Commission on
November 22, 1996, with respect to the registration of the Preferred
Securities, the Guarantees and the Junior Subordinated Debentures (collectively,
the "Securities") under the Securities Act of 1933 (the "Securities Act") (such
Registration Statement, as so amended, including the form of Prospectus relating
to the Securities (the "Prospectus") and the form of Prospectus Supplement
relating to the Preferred Securities (the "Prospectus Supplement") forming a
part thereof, being hereinafter referred to as the "Registration Statement");
(d) the Certificates of Trust of each Trust, each dated October 7, 1996 and
filed with the Secretary of State of Delaware on October 7, 1996; (e) the
Declaration of each Trust; (f) the form of the Amended Declaration of each
Trust; (g) the form of the Base Indenture; (h) the form of the Supplemental
Indenture of each Trust; (i) the form of Preferred Security attached as Annex I
to Exhibit B to the form of the Amended Declaration of each Trust; (j) the form
of Common Security attached as Annex I to Exhibit C to the form of the Amended
Declaration of each Trust; (k) the form of Guarantee Agreement of each Trust;
and (l) the form of Junior Subordinated Debenture set forth in Article V of the
form of Supplemental Indenture of each Trust.

         Based on the foregoing, we are of opinion as follows:

         1. Based solely on a certificate from the Secretary of State of the
State of Delaware, the Company is validly existing as a corporation and in good
standing under the laws of the State of Delaware, with full corporate power and
authority under such laws to own, lease and operate its properties and conduct
its business as described in the Prospectus.

         2. When a Guarantee Agreement of a particular Trust has been duly
authorized, executed and delivered by the Company, assuming the due
authorization, execution and delivery thereof by the Guarantee Trustee, such
Guarantee Agreement and the Guarantees with respect to the Preferred Securities
of such Trust will constitute legal, valid and binding obligations of the

Ladies and Gentlemen:

        We have acted as special Delaware counsel for Paine Webber Group Inc.,
a Delaware corporation ("Paine Webber") and PWG Capital Trust I, a Delaware
business trust (the "Trust"), in connection with the matters set forth herein.
At your request, this opinion is being furnished to you.

        For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

        (a)     The Certificate of Trust of the Trust, dated as of October 7,
1996 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on October 7, 1996;

        (b)     The Declaration of Trust of the Trust, dated as of October 7,
1996, among Paine Webber and the trustees of the Trust named therein;

<PAGE>   2
PWG Capital Trust I
November 22, 1996
Page 2

        (c)     Amendment No. 1 to the Registration Statement (the
"Registration Statement") on Form S-3, including a preliminary prospectus (the
"Prospectus"), relating to the __% Preferred Trust Securities of the Trust,
representing preferred undivided beneficial interests in the assets of the
Trust (each, a "Preferred Security" and collectively, the "Preferred
Securities"), as filed by Paine Webber, the Trust and others as set forth
therein with the Securities and Exchange Commission on November 22, 1996;

        (d)     A form of Amended and Restated Declaration of Trust of the
Trust, to be entered into among Paine Webber, the trustees of the Trust named
therein, and the holders, from time to time, of undivided beneficial interests
in the assets of the Trust (the "Declaration"), filed as an exhibit to the
Registration Statement; and

        (e)     A Certificate of Good Standing for the Trust, dated the date
hereof, obtained from the Secretary of State.

        Initially capitalized terms used herein and not otherwise defined are
used as defined in the Declaration.

        For purposes of this opinion, we have not reviewed any documents other
than the documents listed above, and we have assumed that there exists no
provision in any document that we have not reviewed that bears upon or is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to
be true, complete and accurate in all material respects.

        With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

        For purposes of this opinion, we have assumed (i) that the Declaration
constitutes the entire agreement among the parties thereto with respect to the
subject matter thereof, including with respect to the creation, operation and
termination of the Trust, and that the Declaration and the Certificate are in
full force and effect and have not been amended, (ii) except to the extent
provided in paragraph 1 below, the due creation or due organization or due
formation, as the case may be, and valid existence in good standing of each
party to the documents examined by us under the laws of the jurisdiction
governing its creation, organization or formation, (iii) the legal capacity of
<PAGE>   3
PWG Capital Trust I

Page 3



natural persons who are parties to the documents examined by us, (iv) that each
of the parties to the documents examined by us has the power and authority to
execute and deliver, and to perform its obligations under, such documents, (v)
the due authorization, execution and delivery by all parties thereto of all
documents examined by us, (vi) the receipt by each Person to whom a Preferred
Security is to be issued by the Trust (collectively, the "Preferred Security
Holders") of a Preferred Security Certificate for such Preferred Security and
the payment for the Preferred Security acquired by it, in accordance with the
Declaration and the Registration Statement, and (vii) that the Preferred
Securities are issued and sold to the Preferred Security Holders in accordance
with the Declaration and the Registration Statement. We have not participated
in the preparation of the Registration Statement and assume no responsibility
for its contents.

      This opinion is limited to the laws of the State of Delaware (excluding
the securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal laws
and rules and regulations relating thereto. Our opinions are rendered only with
respect to Delaware laws and rules, regulations and orders thereunder which are
currently in effect.


      Based upon the foregoing, and upon our examination of such questions of
law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

      1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 Del. C.
Sec. 3801, et seq.

      2.  The Preferred Securities to be issued to the Preferred Security
Holders have been duly authorized by the Declaration and will be duly and
validly issued and, subject to the qualifications set forth in paragraph 3
below, fully paid and nonassessable undivided beneficial interests in the
assets of the Trust.

      3.  The Preferred Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Preferred Security
Holders may be obligated, pursuant to the Declaration, to (i) provide indemnity
and security in connection with requests or directions to the Property Trustee
to exercise its rights and remedies under the Declaration, (ii) provide
indemnity and security in connection with
<PAGE>   4

and pay taxes or governmental charges arising from transfers of Preferred
Securities and the issuance of replacement Preferred Security Certificates, and
(iii) undertake as a party litigant to pay costs in any suit for the
enforcement of any right or remedy under the Declaration or against the
Property Trustee, to the extent provided in the Declaration.

      We consent to the filing of this opinion with the Securities and Exchange
Commission as an exhibit to the Registration Statement. In addition, we hereby
consent to the use of our name under the heading "Legal Matters" in the
Prospectus. In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder. Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.



                               Very truly yours,

the Trust, to be entered into among Paine Webber, the trustees of the Trust
named therein, and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust (the "Declaration"), filed as an exhibit to
the Registration Statement; and

                (e)     A Certificate of Good Standing for the Trust, dated the
date hereof, obtained from the Secretary of State.

                Initially capitalized terms used herein and not otherwise
defined are used as defined in the Declaration.

                For purposes of this opinion, we have not reviewed any
documents other than the documents listed above, and we have assumed that there
exists no provision in any document that we have not reviewed that bears upon
or is inconsistent with the opinions stated herein. We have conducted no
independent factual investigation of our own but rather have relied solely upon
the foregoing documents, the statements and information set forth therein and
the additional matters recited or assumed herein, all of which we have assumed
to be true, complete and accurate in all material respects.

                With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                For purposes of this opinion, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Declaration and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the
legal capacity of

natural persons who are parties to the documents examined by us, (iv) that each
of the parties to the documents examined by us has the power and authority to
execute and deliver, and to perform its obligations under, such documents, (v)
the due authorization, execution and delivery by all parties thereto of all
documents examined by us, (vi) the receipt by each Person to whom a Preferred
Security is to be issued by the Trust (collectively, the "Preferred Security
Holders") of a Preferred Security Certificate for such Preferred Security and
the payment for the Preferred Security acquired by it, in accordance with the
Declaration and the Registration Statement, and (vii) that the Preferred
Securities are issued and sold to the Preferred Security Holders in accordance
with the Declaration and the Registration Statement. We have not participated
in the preparation of the Registration Statement and assume no responsibility
for its contents.

        This opinion is limited to the laws of the State of Delaware (excluding
the securities laws of the State of Delaware), and we have not considered and
express no opinion on the laws of any other jurisdiction, including federal
laws and rules and regulations relating thereto. Our opinions are rendered only
with respect to Delaware laws and rules, regulations and orders thereunder
which are currently in effect.

        Based upon the foregoing, and upon our examination of such questions of
law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

        1.      The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act, 12
Del. C. Section 3801, et seq.

        2.      The Preferred Securities to be issued to the Preferred Security
Holders have been duly authorized by the Declaration and will be duly and
validly issued and, subject to the qualifications set forth in paragraph 3
below, fully paid and nonassessable undivided beneficial interests in the
assets of the Trust.

        3.      The Preferred Security Holders, as beneficial owners of the
Trust, will be entitled to the same limitation of personal liability extended
to stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Preferred Security
Holders may be obligated, pursuant to the Declaration, to (i) provide indemnity
and security in connection with requests or directions to the Property Trustee
to exercise its rights and remedies under the Declaration, (ii) provide
indemnity and security in connection with

and pay taxes or governmental charges arising from transfers of Preferred
Securities and the issuance of replacement Preferred Security Certificates, and
(iii) undertake as a party litigant to pay costs in any suit for the
enforcement of any right or remedy under the Declaration or against the
Property Trustee, to the extent provided in the Declaration.

        We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement. In addition,
we hereby consent to the use of our name under the heading "Legal Matters" in
the Prospectus. In giving the foregoing consents, we do not thereby admit that
we come within the category of Persons whose consent is required under Section
7 of the Securities Act of 1933, as amended, or the rules and regulations of
the Securities and Exchange Commission thereunder. Except as stated above,
without our prior written consent, this opinion may not be furnished or quoted
to, or relied upon by, any other Person for any purpose.



                                        Very truly yours,

                                 Debt Securities


Dear Sirs:

                  I have examined and am familiar with the Restated Certificate
of Incorporation of Paine Webber Group Inc., a Delaware corporation (the
"Company"), as amended, and the By-Laws of the Company. I am also familiar with
the corporate proceedings taken by the Company to authorize the offering, from
time to time, by the Company of one or more series of senior debt securities
("Senior Debt Securities") to be issued under an Indenture dated as of March 15,
1988 between the Company and The Chase Manhattan Bank (as amended, the "Senior
Indenture") and/or subordinated debt securities ("Subordinated Debt Securities"
and, together with the "Senior Debt Securities", "Debt Securities") to be issued
under an Indenture dated as of March 15, 1988, between the Company and Chase
Manhattan Bank Delaware (as amended, the "Subordinated Indenture" and, together
with the Senior Indenture, the "Indentures"), such Debt Securities to be in such
aggregate principal amount as may have an aggregate initial public offering
price of up to $500,000,000.

                  On the basis of the foregoing, I am of opinion that:

                  1.  The Company is a duly organized and validly existing 
corporation under the laws of the State of Delaware.

                  2. The issuance and sale of such Debt Securities have been
validly authorized; and such Debt Securities, when duly executed and
authenticated and issued and sold in accordance with the provisions of the
applicable Indenture and issued and sold in accordance with such corporate
proceedings, will be validly authorized and issued and will constitute legal,
valid and binding obligations of the Company enforceable against the Company in
accordance with their terms (subject to applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer and other similar laws affecting
creditors' rights generally from time to time in effect and to general
principles of equity, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing, regardless of whether considered in
a proceeding in equity or at law).

                  I know that I am referred to under the heading "Legal Matters"
in the Prospectus relating to the Debt Securities forming a part of the
Registration Statement on Form S-3 relating to, among other securities, the Debt
Securities and I hereby consent to, such use of my name in the Registration
Statement.

                               PWG Capital Trust I
                           Preferred Trust Securities


Ladies and Gentlemen:

                  We have acted as counsel for Paine Webber Group Inc., a
Delaware corporation (the "Company"), and PWG Capital Trust I, a business trust
created under the Delaware Business Trust Act of the State of Delaware (the
"Trust"), in connection with the proposed issuance by the Trust of Preferred
Trust Securities (the "Preferred Securities") pursuant to the terms of a
Declaration of Trust dated as of October 7, 1996 (the "Declaration"), as amended
and restated by an Amended and Restated Declaration of Trust (as so amended and
restated, the "Amended Declaration"), among the Company, as sponsor, the
trustees named therein and the holders from time to time of undivided beneficial
interests in the assets of the Trust to be dated as of the date of the initial
issuance of Preferred Securities by the Trust. Pursuant to a Guarantee Agreement
(the "Guarantee Agreement"), between the Company and The Chase Manhattan Bank,
as Trustee (the "Guarantee Trustee"), to be dated as of the date of the initial
issuance of Preferred Securities by the Trust, the Preferred Securities will be
guaranteed (the "Guarantee") by the Company with respect to distributions and
payments upon liquidation, redemption or otherwise, as and to the extent set
forth in the Guarantee Agreement. The assets of the Trust will consist of a
series of Junior Subordinated Debt Securities (the "Junior Subordinated 
Debentures") of the Company which will be issued under an Indenture (the "Base
Indenture"), to be entered into by the Company and The Chase Manhattan Bank, as
<PAGE>   2
                                                                               2

Trustee (the "Indenture Trustee"), as supplemented by a Supplemental Indenture
with respect to such series to be entered into by the Company and the Indenture
Trustee (the "Supplemental Indenture" and, together with the Base Indenture, the
"Indenture") as of the date of the initial issuance of Preferred Securities by
the Trust.

                  In that connection, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of such documents,
corporate records and other instruments as we have deemed necessary or
appropriate for the purposes of this opinion, including: (a) the Restated
Certificate of Incorporation of the Company, as amended; (b) the By-laws of the
Company; (c) the Registration Statement on Form S-3 (Registration Nos. 333-13831
and 333-13831-01 filed with the Securities and Exchange Commission (the
"Commission") on October 10, 1996, as amended by Amendment No. 1 thereto filed
with the Commission on November 22, 1996, with respect to the registration of
the Preferred Securities, the Guarantee and the Junior Subordinated Debentures
(collectively, the "Securities") under the Securities Act of 1933 (the
"Securities Act") (such Registration Statement, as so amended, including the
form of Prospectus relating to the Securities (the "Prospectus") and the form of
Prospectus Supplement relating to the Preferred Securities (the "Prospectus
Supplement") forming a part thereof, being hereinafter referred to as the
"Registration Statement"); (d) the Certificate of Trust of the Trust dated
October 7, 1996 and filed with the Secretary of State of the State of Delaware
on October 7, 1996; (e) the Declaration; (f) the form of the Amended
Declaration; (g) the form of the Base Indenture; (h) the form of the
Supplemental Indenture; (i) the form of Preferred Security attached as Annex I
to Exhibit B to the form of Amended Declaration; (j) the form of Common Security
attached as Annex I to Exhibit C to the form of Amended Declaration; (k) the
form of Guarantee Agreement; and (l) the form of Junior Subordinated Debenture
set forth in Article V of the Supplemental Indenture.

                  Based on the foregoing, we are of opinion that the statements
set forth in the Prospectus Supplement under the caption "Taxation", to the
extent they constitute matters of law, accurately describe the material United
States Federal income tax consequences to holders of the ownership and
disposition of the Preferred Securities of the Trust.

                  We do not express any opinion as to any laws other than the
Federal income tax laws of the United States of America.

                  We know that we are referred to in the Prospectus Supplement
under the caption "Taxation", and we hereby consent to such use of our name in
