  Puget Sound Energy Capital Trust I, a trust formed under the laws of the
State of Delaware (the "Trust"), hereby offers, upon the terms and subject to
the conditions set forth in this Prospectus (as the same may be amended or

Pursuant to the Exchange Offer, Puget Sound Energy, a Washington corporation

 THESE SECURITIES HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE  COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS  THE
    SECURITIES AND EXCHANGE  COMMISSION OR ANY  STATE SECURITIES  COMMISSION
     PASSED  UPON  THE  ACCURACY  OR  ADEQUACY  OF  THIS  PROSPECTUS.  ANY

(continued from the previous page).
 
  The Original Capital Securities, the Original Guarantee and the Original
Junior Subordinated Debentures are collectively referred to herein as the
"Original Securities," and the Exchange Capital Securities, the Exchange
Guarantee and the Exchange Junior Subordinated Debentures are collectively
referred to herein as the "Exchange Securities."
 
  The Trust sold the Original Capital Securities in an offering exempt from
the registration requirements of the Securities Act, which was consummated on
June 6, 1997 (the "Closing Date").
 
  The terms of the Exchange Securities are identical in all material respects
to the respective terms of the Original Securities, except that (i) the
Exchange Securities have been registered under the Securities Act and
therefore will not be subject to certain restrictions on transfer applicable
to the Original Securities, (ii) the Exchange Capital Securities will not
contain the $100,000 minimum Liquidation Amount transfer restriction, (iii)
the Exchange Capital Securities will not provide for any increase in the
Distribution rate thereon and (iv) the Exchange Junior Subordinated Debentures
will not provide for any increase in the interest rate thereon. See
"Description of Exchange Securities." The Exchange Capital Securities are
being offered for exchange in order to satisfy certain obligations of the
Corporation and the Trust under the Registration Rights Agreement dated as of
June 6, 1997 (the "Registration Rights Agreement") among the Corporation, the
Trust and the Initial Purchasers (as defined herein). In the event that the
Exchange Offer is consummated, any Original Capital Securities which remain
outstanding after consummation of the Exchange Offer and the Exchange Capital
Securities issued in the Exchange Offer will vote together as a single class
for purposes of determining whether holders of the requisite percentage in
outstanding Liquidation Amount thereof have taken certain actions or exercised
certain rights under the Trust Agreement.
 
  The Exchange Capital Securities and the Original Capital Securities
(collectively, the "Capital Securities") represent beneficial interests in the
assets of the Trust. The Corporation is the owner of all of the beneficial
interests represented by common securities of the Trust (the "Common
Securities" and, together with the Capital Securities, the "Trust
Securities"). The First National Bank of Chicago is the Property Trustee (the
"Property Trustee") of the Trust. The Trust exists for the sole purpose of
issuing the Trust Securities and investing the proceeds thereof in the Junior
Subordinated Debentures (as defined herein). The Junior Subordinated
Debentures will mature on June 1, 2027 (the "Stated Maturity Date"). The
Capital Securities will have a preference over the Common Securities under
certain circumstances with respect to cash distributions and amounts payable
on liquidation, redemption or otherwise. See "Description of Exchange
Securities--Description of Exchange Capital Securities--Subordination of
Common Securities."
 
  As used herein, (i) the "Indenture" means the Indenture, dated as of June 6,
1997, as amended and supplemented from time to time, between the Corporation
and The First National Bank of Chicago, as trustee (the "Debenture Trustee"),
relating to the Junior Subordinated Debentures, (ii) the "Trust Agreement"
means the Amended and Restated Declaration of Trust relating to the Trust
among the Corporation, as Sponsor, The First National Bank of Chicago, as
Property Trustee, First Chicago Delaware Inc., an affiliate of the Property
Trustee, as Delaware Trustee (the "Delaware Trustee"), and the Administrative
Trustees named therein (collectively, with the Property Trustee and Delaware
Trustee, the "Issuer Trustees"), (iii) the "Guarantee" means the Guarantee
Agreement relating to the Capital Securities between the Corporation and The
First National Bank of Chicago, as trustee (the "Guarantee Trustee") and (iv)
the "Common Guarantee" means the Guarantee Agreement relating to the Common
Securities between the Corporation and The First National Bank of Chicago, as
trustee. In addition, as the context may require, (i) "Junior Subordinated
Debentures" includes the Original Junior Subordinated Debentures and the
Exchange Junior Subordinated Debentures and (ii) "Guarantee" includes the
Original Guarantee and the Exchange Guarantee.
 
  Holders of the Capital Securities and the Common Securities will be entitled
to receive preferential cumulative cash distributions arising from the payment
of interest on the Junior Subordinated Debentures, accruing from the date of
original issuance and payable semi-annually in arrears on June 1 and December
1 of
 
                                       2
<PAGE>
 
each year, commencing December 1, 1997, at the annual rate of 8.231% of the
Liquidation Amount of $1,000 per Trust Security ("Distributions"). So long as
no Debenture Event of Default (as defined herein) has occurred and is
continuing, the Corporation will have the right to defer payments of interest
on the Junior Subordinated Debentures at any time and from time to time for a
period not exceeding 10 consecutive semi-annual periods with respect to each
deferral period (each, an "Extension Period"), provided that no Extension
Period may extend beyond the Stated Maturity Date. Upon the termination of any
such Extension Period and the payment of all amounts then due, the Corporation
may elect to begin a new Extension Period, subject to the requirements set
forth herein. If and for so long as interest payments on the Junior
Subordinated Debentures are so deferred, Distributions on the Trust Securities
will also be deferred and the Corporation will not be permitted, subject to
certain exceptions described herein, to declare or pay any cash distributions
with respect to the Corporation's capital stock (which includes common and
preferred stock) or to make any payment with respect to debt securities of the
Corporation that rank pari passu with or junior to the Junior Subordinated
Debentures. During an Extension Period, interest on the Junior Subordinated
Debentures will continue to accrue (and the amount of Distributions to which
holders of the Trust Securities are entitled will continue to accumulate) at
the rate of 8.231% per annum, compounded semi-annually, and holders of Trust
Securities will be required to accrue interest income for United States
federal income tax purposes prior to the receipt of the cash attributable to
such income. See "Description of Exchange Securities--Description of Exchange
Junior Subordinated Debentures--Option to Extend Interest Payment Date" and
"Certain Federal Income Tax Consequences--Interest Income and Original Issue
Discount."
 
  The Corporation will, through the Guarantee, the Common Guarantee, the Trust
Agreement, the Junior Subordinated Debentures and the Indenture, taken
together, fully, irrevocably and unconditionally guarantee all of the Trust's
obligations under the Trust Securities. See "Relationship Among the Exchange
Capital Securities, the Exchange Junior Subordinated Debentures and the
Exchange Guarantee--Full and Unconditional Guarantee." The Guarantee and the
Common Guarantee will guarantee payments of Distributions and payments on
liquidation or redemption of the Trust Securities, but in each case only to
the extent that the Trust holds funds on hand legally available therefor and
has failed to make such payments, as described herein. See "Description of
Exchange Securities--Description of Exchange Guarantee." If the Corporation
fails to make a required payment on the Junior Subordinated Debentures, the
Trust will not have sufficient funds to make the related payments, including
Distributions, on the Trust Securities. The Guarantee and the Common Guarantee
will not cover any such payment when the Trust does not have sufficient funds
on hand legally available therefor. In such event, a holder of Capital
Securities may institute a legal proceeding directly against the Corporation
to enforce its rights in respect of such payment. See "Description of Exchange
Securities--Description of Exchange Junior Subordinated Debentures--
Enforcement of Certain Rights by Holders of Capital Securities." The
obligations of the Corporation under the Guarantee, the Common Guarantee and
the Junior Subordinated Debentures will be unsecured and subordinate and
junior in right of payment to all Senior Indebtedness (as defined in
"Description of Exchange Securities--Description of Exchange Junior
Subordinated Debentures--Subordination"), which aggregated approximately $1.4
billion as of June 30, 1997.
 
  The Trust Securities will be subject to mandatory redemption in a Like
Amount (as defined herein), (i) in whole but not in part, on the Stated
Maturity Date upon repayment of the Junior Subordinated Debentures at a
redemption price equal to the principal amount of, plus accrued and unpaid
interest on, the Junior Subordinated Debentures (the "Maturity Redemption
Price"), (ii) in whole but not in part, contemporaneously with the optional
prepayment of the Junior Subordinated Debentures at any time prior to June 1,
2007 upon the occurrence and continuation of a Tax Event (as defined herein)
at a redemption price equal to the Tax Event Prepayment Price (as defined
below), and (iii) in whole or in part, on or after June 1, 2007,
contemporaneously with the optional prepayment by the Corporation of the
Junior Subordinated Debentures, at a redemption price equal to the Optional
Prepayment Price (as defined below). Any of the Maturity Redemption Price, the
Tax Event Redemption Price and the Optional Redemption Price may be referred
to herein as the "Redemption Price." See "Description of Exchange Securities--
Description of Exchange Capital Securities--Redemption."
 
  The Junior Subordinated Debentures will be prepayable prior to the Stated
Maturity Date at the option of the Corporation (i) on or after June 1, 2007,
in whole or in part, at a prepayment price (the "Optional Prepayment
 
                                       3
<PAGE>
 
Price") equal to 104.116% of the principal amount thereof on June 1, 2007,
declining ratably on each June 1 thereafter to 100% on or after June 1, 2017,
plus accrued and unpaid interest thereon to the date of prepayment, or (ii) in
whole but not in part, at any time prior to June 1, 2007, in whole but not in
part, upon the occurrence and continuation of a Tax Event, at a prepayment
price (the "Tax Event Prepayment Price") equal to the greater of (a) 100% of
the principal amount thereof or (b) the sum, as determined by a Quotation
Agent (as defined hereinafter), of the present values of the remaining
scheduled payments of principal and interest on the Junior Subordinated
Debentures to the Stated Maturity Date, discounted to the prepayment date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate (as defined herein) plus, in either case,
accrued and unpaid interest thereon to the date of prepayment. Either of the
Optional Prepayment Price or the Tax Event Prepayment Price may be referred to
herein as the "Prepayment Price." See "Description of Exchange Securities--
Description of Exchange Junior Subordinated Debentures--Optional Prepayment"
and "--Tax Event Prepayment."
 
  The Corporation will have the right at any time to terminate the Trust and
cause a Like Amount of the Junior Subordinated Debentures to be distributed to
the holders of the Trust Securities in liquidation of the Trust, subject to
the Corporation having received an opinion of counsel to the effect that such
distribution will not be a taxable event to holders of Capital Securities.
Unless the Junior Subordinated Debentures are distributed to the holders of
the Trust Securities, in the event of a liquidation of the Trust as described
herein, after satisfaction of liabilities to creditors of the Trust as
required by applicable law, the holders of the Trust Securities generally will
be entitled to receive a Liquidation Amount of $1,000 per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment. See
"Description of Exchange Securities--Description of Exchange Capital
Securities--Liquidation of the Trust and Distribution of Junior Subordinated
Debentures."
 
  Prior to the Exchange Offer, there has been only a limited secondary market
and no public market for the Original Capital Securities. The Exchange Capital
Securities will be a new issue of securities for which there currently is no
market. Although Smith Barney Inc., Goldman, Sachs & Co. and Salomon Brothers
Inc, the initial purchasers of the Original Capital Securities (the "Initial
Purchasers"), have informed the Corporation and the Trust that they each
currently intend to make a market in the Exchange Capital Securities, they are
not obligated to do so, and any such market making may be discontinued at any
time without notice. Accordingly, there can be no assurance as to the
development or liquidity of any market for the Exchange Capital Securities.
The Corporation and the Trust currently do not intend to apply for listing of
the Exchange Capital Securities on any securities exchange or for quotation
through the NASD Automated Quotation System.
 
  Any Original Capital Securities not tendered and accepted in the Exchange
Offer will remain outstanding and will be entitled to all the same rights and
will be subject to the same limitations applicable thereto under the
Declaration (except for those rights which terminate upon consummation of the
Exchange Offer). Following consummation of the Exchange Offer, the holders of
Original Capital Securities will continue to be subject to all of the existing
restrictions upon transfer thereof and neither the Corporation nor the Trust
will have any further obligation to such holders (other than under certain
limited circumstances) to provide for registration under the Securities Act of
the Original Capital Securities held by them. To the extent that Original
Capital Securities are tendered and accepted in the Exchange Offer, a holder's
ability to sell untendered Original Capital Securities could be adversely
affected. See "Risk Factors--Consequences of a Failure to Exchange Original
Capital Securities."
 
  THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF ORIGINAL CAPITAL SECURITIES ARE URGED TO READ THIS
PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING
WHETHER TO TENDER THEIR ORIGINAL CAPITAL SECURITIES PURSUANT TO THE EXCHANGE
OFFER.
 
  Original Capital Securities may be tendered for exchange on or prior to 5:00
p.m., New York City time, on     , 1997 (such time on such date being
hereinafter called the "Expiration Date"), unless the Exchange Offer is
extended by the Corporation or the Trust (in which case the term "Expiration
Date" shall mean the
 
                                       4
<PAGE>
 
latest date and time to which the Exchange Offer is extended). Tenders of
Original Capital Securities may be withdrawn at any time on or prior to the
Expiration Date. The Exchange Offer is not conditioned upon any minimum
Liquidation Amount of Original Capital Securities being tendered for exchange.
However, the Exchange Offer is subject to certain events and conditions which
may be waived by the Corporation or the Trust and to the terms and provisions
of the Registration Rights Agreement. Original Capital Securities may be
tendered in whole or in part having an aggregate Liquidation Amount of not
less than $100,000 (100 Capital Securities) or any integral multiple of $1,000
Liquidation Amount (one Capital Security) in excess thereof. The Corporation
has agreed to pay all expenses of the Exchange Offer. See "The Exchange
Offer--Fees and Expenses." Holders of the Original Capital Securities as of
November 15, 1997 will receive the Distribution to be paid on December 1,
1997. Holders of the Original Capital Securities whose Original Capital

Resales of Exchange Capital
Securities..................
                              The Trust is making the Exchange Offer of the
                              Exchange Capital Securities in reliance on the
                              position of the staff of the Division of
                              Corporation Finance of the Commission as set
                              forth in certain interpretive letters addressed
                              to third parties in other transactions. However,
                              neither the Corporation nor the Trust has sought
                              its own interpretive letter and there can be no
                              assurance that the staff of the Division of
                              Corporation Finance of the Commission would make
                              a similar determination with respect to the
                              Exchange Offer as it has in such interpretive
                              letters to third parties. Based on these
                              interpretations by the staff of the Division of
                              Corporation Finance of the Commission, and
                              subject to the two immediately following
                              sentences, the Corporation and the Trust believe
                              that Exchange Capital Securities issued pursuant
                              to this Exchange Offer in exchange for Original
                              Capital Securities may be offered for resale,
                              resold and otherwise transferred by a holder
                              thereof (other than a holder who is a broker-
                              dealer) without further compliance with the
                              registration and prospectus delivery requirements
                              of the Securities Act, provided that such
                              Exchange Capital Securities are acquired in the
                              ordinary course of such holder's business and
                              that such holder is not participating, and has no
                              arrangement or understanding with any person to
                              participate, in a distribution (within the
                              meaning of the Securities Act) of such Exchange
                              Capital Securities. However, any holder of
                              Original Capital Securities who is an "affiliate"
                              of the Corporation or the Trust or who intends to
                              participate in the Exchange Offer for the purpose
                              of distributing Exchange Capital Securities, or
                              any broker-dealer who purchased Original Capital
                              Securities from the Trust to resell pursuant to
                              Rule 144A under the Securities Act ("Rule 144A")
                              or any other available exemption under the
                              Securities Act, (a) will not be able to rely on
                              the interpretations of the staff of the Division
                              of Corporation Finance of the Commission set
                              forth in the above-mentioned interpretive
                              letters, (b) will not be permitted or entitled to
                              tender such Original Capital

                              Securities in the Exchange Offer and (c) must
                              comply with the registration and prospectus
                              delivery requirements of the Securities Act in
                              connection with any sale or other transfer of
                              such Original Capital Securities unless such sale
                              is made pursuant to an exemption from such
                              requirements. In addition, as described below, if

                              Each broker-dealer that receives Exchange Capital
                              Securities for its own account pursuant to the

                              the Original Capital Securities for its own
                              account as the result of market-making activities
                              or other trading activities and must agree that

                              Securities. The Letter of Transmittal states that
                              by so acknowledging and by delivering a
                              prospectus, a broker-dealer will not be deemed to
                              admit that it is an "underwriter" within the
                              meaning of the Securities Act.
 
                              Based on the position taken by the staff of the
                              Division of Corporation Finance of the Commission
                              in the interpretive letters referred to above,
                              the Corporation and the Trust believe that
                              broker-dealers who acquired Original Capital
                              Securities for their own accounts, as a result of

                              fulfill their prospectus delivery requirements
                              with respect to the Exchange Capital Securities
                              received upon exchange of such Original Capital
                              Securities (other than Original Capital
                              Securities which represent an unsold allotment

                              Exchange Capital Securities. Each broker-dealer
                              that receives Exchange Capital Securities for its
                              own account pursuant to the Exchange Offer must

                              states that by so acknowledging and by delivery
                              of a prospectus, a broker-dealer will not be
                              deemed to admit that it is an "underwriter"
                              within the meaning of the Securities Act. This
                              Prospectus, as it may be amended or supplemented
                              from time to time, may be used by a broker-dealer

                              as a result of market-making activities or other
                              trading activities. The Trust and the Corporation
                              have agreed that, ending on the close of business

                              June 1, 1998. The Distribution payable December
                              1, 1997 will be paid to the holders as of
                              November 15, 1997 of the Original Capital

Extension Periods...........  Distributions on Exchange Capital Securities will
                              be deferred for the duration of any Extension
                              Period elected by the Corporation with respect to
                              the payment of interest on the Exchange Junior
                              Subordinated Debentures. No Extension Period will
                              exceed 10 consecutive semi-annual periods or
                              extend beyond the Stated Maturity Date. See
                              "Description of Exchange Securities--Description

Ranking.....................  The Exchange Capital Securities will rank pari
                              passu, and payments thereon will be made pro
                              rata, with the Original Capital Securities and
                              the Common Securities except as described in

                              Common Securities." The Exchange Junior
                              Subordinated Debentures will rank pari passu with
                              the Original Junior Subordinated Debentures and
                              all other junior subordinated debentures to be
                              issued by the Corporation ("Other Debentures"),
                              which will be issued and sold (if at all) to
                              other trusts to be established by the Corporation
                              (if any), in each case similar to the Trust
                              ("Other Trusts"), and will be unsecured and
                              subordinate and junior in right of payment to all
                              Senior Indebtedness to the extent and in the
                              manner set forth in the Indenture. See
                              "Description of Exchange Securities--Description

                              respect to capital or preferred securities (if
                              any) issued by Other Trusts ("Other Guarantees")
                              and will constitute an unsecured obligation of
                              the Corporation and will rank subordinate and
                              junior in right of payment to all Senior
                              Indebtedness to the extent and in the manner set
                              forth in the Guarantee Agreement. See

                              of Exchange Guarantee."
 
Redemption..................  The Trust Securities will be subject to mandatory
                              redemption in a Like Amount, (i) in whole but not
                              in part, on the Stated Maturity Date upon
                              repayment of the Junior Subordinated Debentures,
                              (ii) in whole but not in part, contemporaneously
                              with the optional prepayment of the Junior
                              Subordinated Debentures by the Corporation, at
                              any time prior to June 1, 2007, upon the
                              occurrence and continuation of a Tax Event and
                              (iii) in whole or in part, on or after June 1,
                              2007 contemporaneously with the optional
                              prepayment by the Corporation of the Junior
                              Subordinated Debentures, in each case at the
                              applicable Redemption Price. See "Description of
                              Exchange Securities--Description of Exchange
                              Capital Securities--Redemption."
 
Ratings.....................  The Exchange Capital Securities are expected to
                              be rated baa2 by Moody's Investors Service, Inc.
                              and "BBB" by Standard & Poor's Rating Services.
 
Transfer Restrictions.......  The Exchange Capital Securities will be issued,
                              and may be transferred, only in minimum
                              denominations of not less than $1,000. See
                              "Description of Exchange Securities--Description
                              of Exchange Capital Securities--Restrictions on
                              Transfer." Any such transfer of Exchange Capital
                              Securities in denominations of less than $1,000
                              shall be deemed to be void and of no legal effect
                              whatsoever.
 
Absence of Market for the
Capital Securities..........
                              The Exchange Capital Securities will be a new
                              issue of securities for which there currently is
                              no market. Although the Initial Purchasers have
                              informed the Trust and the Corporation that they
                              each currently intend to make a market in the
                              Capital Securities, the Initial Purchasers are
                              not obligated to do so, and any such market-
                              making may be discontinued at any time without
                              notice. Accordingly, there can be no assurance as
                              to the development or liquidity of any market for
                              the Capital Securities. The Trust and the
                              Corporation do not intend to apply for listing of
                              the Capital Securities on any securities exchange
                              or for quotation through the NASD Automated
                              Quotation System. See "Plan of Distribution."

of Exchange Securities" and "Certain Federal Income Tax Consequences."

                                 RISK FACTORS
 
  The Corporation identifies the following important factors which could cause
actual results to differ materially from any results that might be projected,
forecast, estimated or budgeted by the Corporation as forward-looking
information. All such factors are difficult to predict and the majority are
beyond the control of the Corporation. Holders of Original Capital Securities
should carefully review the information contained elsewhere in this Prospectus
and should particularly consider the information stated below. See "Forward-
Looking Information."
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES
 
  The obligations of the Corporation under the Guarantee issued by it for the
benefit of the holders of Capital Securities, as well as under the Junior
Subordinated Debentures, will be unsecured and rank subordinate and junior in
right of payment to all Senior Indebtedness. In addition, in the case of a
bankruptcy or insolvency proceeding, the Corporation's obligations under the
Guarantee will also rank subordinate and junior in right of payment to all
liabilities (other than Other Guarantees) of the Corporation. At June 30,
1997, the aggregate principal amount of outstanding Senior Indebtedness was
approximately $1.4 billion. None of the Indenture, the Guarantee or the Trust
Agreement places any limitation on the amount of secured or unsecured debt,
including Senior Indebtedness, that may be incurred by the Corporation or by
any subsidiary. See "Description of Exchange Securities--Description of
Exchange Guarantee--Status of the Exchange Guarantee" and "Description of
Exchange Securities--Description of Exchange Junior Subordinated Debentures--
Subordination."
 
  The ability of the Trust to pay amounts due on the Capital Securities is
solely dependent upon the Corporation's making payments on the Junior
Subordinated Debentures as and when required.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSIDERATIONS
 
  So long as no Debenture Event of Default (as defined in "Description of
Exchange Securities--Description of Exchange Junior Subordinated Debentures--
Debenture Events of Default") shall have occurred and be continuing, the
Corporation will have the right under the Indenture to defer payments of
interest on the Junior Subordinated Debentures at any time or from time to
time for a period not exceeding 10 consecutive semi-annual periods with
respect to each Extension Period, provided that no Extension Period may extend
beyond the Stated Maturity Date. As a consequence of any such deferral, semi-
annual Distributions on the Capital Securities by the Trust will be deferred
(and the amount of Distributions to which holders of the Capital Securities
are entitled will accumulate additional Distributions thereon at the rate of
8.231% per annum, compounded semi-annually), from the relevant payment date
for such Distributions during any such Extension Period.
 
  Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive semi-annual periods or to
extend beyond the Stated Maturity Date. Upon the termination of any Extension
Period and the payment of all interest then accrued and unpaid on the Junior
Subordinated Debentures (together with interest thereon at the annual rate of
8.231%, compounded semi-annually, to the extent permitted by applicable law),
the Corporation may elect to begin a new Extension Period, subject to the
above requirements. There is no limitation on the number of times that the
Corporation may elect to begin an Extension Period. See "Description of
Exchange Securities--Description of Exchange Capital Securities--
Distributions" and "Description of Exchange Securities--Description of
Exchange Junior Subordinated Debentures--Option to Extend Interest Payment
Date."
 
  Should the Corporation exercise its right to defer payments of interest on
the Junior Subordinated Debentures, each holder of Trust Securities will be
required to accrue income (as original issue discount ("OID")) in respect of
the deferred stated interest allocable to its Trust Securities for United
States federal income tax purposes, which will be allocated but not
distributed to holders of Trust Securities. As a result, each
 
                                      15
<PAGE>
 
such holder of Capital Securities will recognize income for United States
federal income tax purposes in advance of the receipt of cash and will not
receive the cash related to such income from the Trust if the holder disposes
of the Capital Securities prior to the record date for the payment of
Distributions thereafter. See "Certain Federal Income Tax Consequences--
Interest Income and Original Issue Discount" and "--Sales of Capital
Securities."
 
  Should the Corporation elect to exercise its right to defer payments of
interest on the Junior Subordinated Debentures in the future, the market price
of the Capital Securities is likely to be affected. A holder that disposes of
its Capital Securities during an Extension Period, therefore, might not
receive the same return on its investment as a holder that continues to hold
its Capital Securities. In addition, merely as a result of the existence of
the Corporation's right to defer payments of interest on the Junior
Subordinated Debentures, the market price of the Capital Securities may be
more volatile than the market prices of other securities that are not subject
to such deferrals.
 
  Although the Corporation has the right to exercise its option to defer
payments of interest on the Junior Subordinated Debentures, the Corporation
has no current intention to defer payments of interest on such debentures.
 
TAX EVENT REDEMPTION; POSSIBLE TAX LAW CHANGES AFFECTING THE CAPITAL
SECURITIES
 
  Upon the occurrence and continuation of a Tax Event (as defined in
"Description of Exchange Securities--Description of Exchange Junior
Subordinated Debentures--Tax Event Prepayment"), the Corporation will have the
right to prepay the Junior Subordinated Debentures in whole (but not in part)
at the Tax Event Prepayment Price prior to June 1, 2007 and within 90 days
following the occurrence of such Tax Event and therefore cause a mandatory
redemption of the Trust Securities at the Tax Event Redemption Price. See
"Description of Exchange Securities--Description of Exchange Capital
Securities--Redemption."
 
  The Taxpayer Relief Act of 1997, enacted on August 7, 1997, did not contain
certain provisions of President Clinton's Fiscal Budget Proposal (the
"Proposed Legislation") that, among other things, would have denied an issuer
a deduction for United States federal income tax purposes for the payment of
interest on instruments with characteristics similar to the Junior
Subordinated Debentures. There can be no assurance, however, that the Proposed
Legislation or other legislation enacted after the date hereof would not
adversely affect the tax treatment of the Junior Subordinated Debentures or
that any legislation enacted after the date hereof would not cause a Tax Event
that may result in the redemption of the Junior Subordinated Debentures and,
consequently, the Trust Securities. See "Description of Exchange Securities--
Description of Exchange Capital Securities--Redemption" and "Description of
Exchange Securities--Description of Exchange Junior Subordinated Debentures--
Tax Event Prepayment." See also "Certain Federal Income Tax Consequences--
Proposed Tax Legislation."
 
POSSIBLE ADVERSE EFFECT ON MARKET PRICES
 
  There can be no assurance as to the market prices for Capital Securities or
Junior Subordinated Debentures distributed to the holders of Capital
Securities if a termination of the Trust were to occur. Accordingly, the
Capital Securities or the Junior Subordinated Debentures may trade at a
discount from the price that the investor paid to purchase the Capital
Securities offered hereby. Because holders of Capital Securities may receive
Junior Subordinated Debentures in liquidation of the Trust and because
Distributions are otherwise limited to payments on the Junior Subordinated
Debentures, prospective purchasers of Exchange Capital Securities are also
making an investment decision with regard to the Exchange Junior Subordinated
Debentures and should carefully review all the information regarding the
Exchange Junior Subordinated Debentures contained herein. See "Description of
Exchange Securities--Description of Exchange Junior Subordinated Debentures."
 
RIGHTS UNDER THE GUARANTEE
 
  The First National Bank of Chicago will act as Guarantee Trustee and will
hold the Guarantee for the benefit of the holders of the Capital Securities.
The First National Bank of Chicago will also act as Property Trustee and
 
                                      16
<PAGE>
 
as Debenture Trustee under the Indenture. First Chicago Delaware Inc. will act
as Delaware Trustee under the Trust Agreement. The Guarantee will guarantee to
the holders of the Capital Securities the following payments, to the extent
not paid by the Trust: (i) any accumulated and unpaid Distributions required
to be paid on the Capital Securities, to the extent that the Trust has funds
on hand legally available therefor at such time, (ii) the applicable
Redemption Price with respect to any Capital Securities called for redemption,
to the extent that the Trust has funds on hand legally available therefor at
such time, and (iii) upon a voluntary or involuntary termination and
liquidation of the Trust (unless the Junior Subordinated Debentures are
distributed to holders of the Capital Securities), the lesser of (a) the
aggregate of the Liquidation Amount and all accumulated and unpaid
Distributions to the date of payment, to the extent that the Trust has funds
on hand legally available therefor at such time and (b) the amount of assets
of the Trust remaining available for distribution to holders of the Capital
Securities upon a termination and liquidation of the Trust. The holders of a
majority in Liquidation Amount of the Capital Securities will have the right
to direct the time, method and place of conducting any proceeding for any
remedy available to the Guarantee Trustee in respect of the Guarantee or to
direct the exercise of any trust power conferred upon the Guarantee Trustee.
Any holder of the Capital Securities may institute a legal proceeding directly
against the Corporation to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Trust, the Guarantee Trustee
or any other person or entity. If the Corporation defaults on its obligation
to pay amounts payable under the Junior Subordinated Debentures, the Trust
will not have sufficient funds for the payment of Distributions or amounts
payable on redemption of the Capital Securities or otherwise, and, in such
event, holders of the Capital Securities will not be able to rely upon the
Guarantee for payment of such amounts. Instead, in the event a Debenture Event
of Default shall have occurred and be continuing and such event is
attributable to the failure of the Corporation to pay principal of (or
premium, if any) or interest on the Junior Subordinated Debentures on the
payment date on which such payment is due and payable, then a holder of
Capital Securities may institute a legal proceeding directly against the
Corporation for enforcement of payment to such holder of the principal of (or
premium, if any) or interest on such Junior Subordinated Debentures having a
principal amount equal to the Liquidation Amount of the Capital Securities of
such holder (a "Direct Action"). Notwithstanding any payments made to a holder
of Capital Securities by the Corporation in connection with a Direct Action,
the Corporation shall remain obligated to pay the principal of (and premium,
if any) and interest on the Junior Subordinated Debentures, and the
Corporation shall be subrogated to the rights of the holder of such Capital
Securities with respect to payments on the Capital Securities to the extent of
any payments made by the Corporation to such holder in any Direct Action.
Except as described herein, holders of Capital Securities will not be able to
exercise directly any other remedy available to the holders of the Junior
Subordinated Debentures or to assert directly any other rights in respect of
the Junior Subordinated Debentures. See "Description of Exchange Securities--
Description of Exchange Junior Subordinated Debentures--Enforcement of Certain
Rights by Holders of Capital Securities," "--Description of Exchange Junior
Subordinated Debentures--Debenture Events of Default" and "--Description of
Exchange Guarantee." The Trust Agreement will provide that each holder of
Capital Securities by acceptance thereof agrees to the provisions of the
Indenture.
 
CONSEQUENCES OF HIGHLY LEVERAGED TRANSACTION
 
  The Indenture does not contain provisions that afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged
transaction, including a change of control, or other similar transactions
involving the Corporation that may adversely affect such holders.
 
LIMITED VOTING RIGHTS
 
  Holders of Capital Securities will generally have voting rights relating
only to the modification of the Capital Securities, the termination or
liquidation of the Trust, and the exercise of the Trust's rights as holder of
Junior Subordinated Debentures. Holders of Capital Securities will not be
entitled to vote to appoint, remove or replace the Property Trustee or the
Delaware Trustee, and such voting rights are vested exclusively in the holder
of the Common Securities except upon the occurrence of certain events
described herein. See "Description of Exchange Securities--Description of
Exchange Capital Securities--Voting Rights; Amendment of the Trust Agreement"
and "--Removal of Issuer Trustees."
 
                                      17

CONSEQUENCES OF A FAILURE TO EXCHANGE ORIGINAL CAPITAL SECURITIES
 
  The Original Capital Securities have not been registered under the
Securities Act or any state securities laws and therefore may not be offered,
sold or otherwise transferred except in compliance with the registration
requirements of the Securities Act and any other applicable securities laws,
or pursuant to an exemption therefrom or in a transaction not subject thereto,
and in each case in compliance with certain other conditions and restrictions.
Original Capital Securities which remain outstanding after consummation of the
Exchange Offer will continue to bear a legend reflecting such restrictions on
transfer. In addition, upon consummation of the Exchange Offer, holders of
Original Capital Securities which remain outstanding will not be entitled to
any rights to have such Original Capital Securities registered under the
Securities Act or to any similar rights under the Registration Rights
Agreement (subject to certain limited exceptions). The Corporation and the
Trust do not intend to register under the Securities Act any Original Capital
Securities which remain outstanding after consummation of the Exchange Offer
(subject to such limited exceptions, if applicable). To the extent that
Original Capital Securities are tendered and accepted in the Exchange Offer, a
holder's ability to sell untendered Original Capital Securities could be
adversely affected.
 
  The Exchange Capital Securities and any Original Capital Securities which
remain outstanding after consummation of the Exchange Offer will vote together
as a single class for purposes of determining whether holders of the requisite
percentage in outstanding Liquidation Amount of Capital Securities have taken
certain actions or exercised certain rights under the Declaration. See
"Description of Exchange Securities--Description of Exchange Capital
Securities--Voting Rights; Amendment of the Trust Agreement."
 
  The Original Capital Securities provide, among other things, that, if a
registration statement relating to the Exchange Offer has not been filed by
November 3, 1997 and declared effective by December 3, 1997, the Distribution
rate borne by the Original Capital Securities will increase by 0.25% per annum
until such registration statement has been filed or declared effective, as the
case may be. Upon consummation of the Exchange Offer, holders of Original
Capital Securities will not be entitled to any increase in the Distribution
rate thereon or any further registration rights under the Registration Rights
Agreement, except under limited circumstances. See "Description of Exchange
Securities."
 
ABSENCE OF PUBLIC MARKET
 
  The Original Capital Securities were issued to, and the Corporation believes
such securities are currently owned by, a relatively small number of
beneficial owners. The Original Capital Securities have not been registered
under the Securities Act and will be subject to restrictions on
transferability if they are not exchanged for the Exchange Capital Securities.
Although the Exchange Capital Securities may be resold or otherwise
transferred by the holders (who are not affiliates of the Corporation or the
Trust) without compliance with the registration requirements under the
Securities Act, they will constitute a new issue of securities with no
established trading market. Original Capital Securities may be transferred by
the holders thereof only in blocks having a Liquidation Amount of not less
than $100,000 (100 Capital Securities). The Corporation and the Trust have
been advised by the Initial Purchasers that the Initial Purchasers presently
intend to make a market in the Exchange Capital Securities. However, the
Initial Purchasers are not obligated to do so and any market-making activity
with respect to the Exchange Capital Securities may be discontinued at any
time without notice. In addition, such market-making activity will be subject
to the limits imposed by the Securities Act and the Exchange Act and may be
limited during the Exchange Offer. Accordingly, no assurance can be given that
an active public or other market will develop for the Exchange Capital
Securities or the Original Capital Securities, or as to the liquidity of or
the trading market for the Exchange Capital Securities or the Original Capital
Securities. If an active public market does not develop, the market price and
liquidity of the Exchange Capital Securities may be adversely affected.
 
  If a public trading market develops for the Exchange Capital Securities,
future trading prices will depend on many factors, including, among other
things, prevailing interest rates, the financial condition of the
 
                                      18
<PAGE>
 
Corporation and the market for similar securities. Depending on these and
other factors, the Exchange Capital Securities may trade at a discount.
 
  Notwithstanding the registration of the Exchange Capital Securities in the
Exchange Offer, holders who are "affiliates" (as defined under Rule 405 of the
Securities Act) of the Corporation or the Trust may publicly offer for sale or
resell the Exchange Capital Securities only in compliance with the provisions
of Rule 144 under the Securities Act. Each broker-dealer that receives
Exchange Capital Securities for its own account in exchange for Original
Capital Securities, where such Original Capital Securities were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Capital Securities. See "Plan of
Distribution."
 
EXCHANGE OFFER PROCEDURES
 
  Subject to the conditions set forth in "The Exchange Offer--Conditions to
the Exchange Offer," delivery of Exchange Capital Securities in exchange for
Original Capital Securities tendered and accepted for exchange pursuant to the
Exchange Offer will be made only after timely receipt by the Exchange Agent of
(i) certificates for Original Capital Securities or a book-entry confirmation

a territory covering approximately 6,000 square miles, principally in the
Puget Sound region of Washington state. On February 10, 1997, the Corporation
completed a merger (the "Merger") with the Washington Energy Company ("WECo")
and its principal subsidiary, Washington Natural Gas Company ("WNG"). Seattle-
based WNG provided natural gas distribution service to more than 500,000
customers in an areas east of Puget Sound that included Seattle, Tacoma,
Everett, Bellevue and Olympia. The Corporation changed its name to Puget Sound

industrial and 1,400 other customers and approximately 508,900 gas customers,
consisting of 463,800 residential, 42,000 commercial, 3,000 industrial and 100
other customers. For the first six months of 1997, the Corporation added

the Corporation's billed revenues from electric utility operations were
derived 47% from residential customers, 35% from commercial customers, 14%
from industrial customers and 4% from sales to other utilities and others, and
the Corporation's billed revenues from gas utility operations were derived 60%
from residential customers, 23% from commercial customers, 11% from industrial
customers and 6% from other customers. During this period, the largest single
electric customer accounted for 3.3% of the Corporation's electric utility
operating revenues, and the largest single gas customer accounted for 0.5% of
the Corporation's gas utility operating revenues.
 
  Gross electric utility plant at December 31, 1996, was approximately $3.5
billion, which consisted of 47% distribution, 27% generation, 15% transmission
and 11% general plant and other. Gross gas utility plant at September 30,
1996, was approximately $1.1 billion, which consisted of 86% distribution, 4%

                                USE OF PROCEEDS
 
  This Exchange Offer is intended to satisfy certain obligations of the
Corporation under the Registration Rights Agreement. Neither the Corporation
nor the Trust will receive any proceeds from the issuance of the Exchange
Capital Securities and the Exchange Guarantee offered hereby and has agreed to
pay the expenses of the Exchange Offer. In consideration for issuing the
Exchange Capital Securities as contemplated in this Prospectus, the Trust will
receive, in exchange, Original Capital Securities in like Liquidation Amount.
The Original Capital Securities surrendered in exchange for the Exchange
Capital Securities will be retired and canceled and cannot be re-issued.
 
  The proceeds to the Trust (without giving effect to expenses of the offering
payable by the Corporation) from the offering of the Original Capital
Securities was $100,000,000. All of the proceeds from the sale of the Original
Capital Securities were invested by the Trust in the Original Junior
Subordinated Debentures. The net proceeds from the sale of the Original Junior
Subordinated Debentures were used initially to reduce the Corporation's short-
term debt and ultimately to fund a portion of the redemption and repurchase of
certain of the Corporation's preferred stock, as well as other general
corporate purposes, including working capital. The form and terms of the
Exchange Junior Subordinated Debentures are identical in all material respects
to the form and terms of the Original Junior Subordinated Debentures, except
as otherwise described in "Description of Exchange Securities--Description of
Exchange Junior Subordinated Debentures." Accordingly, issuance of the
Exchange Junior Subordinated Debentures will not result in any increase in the
outstanding debt of the Corporation.
 
 RATIOS OF EARNINGS TO FIXED CHARGES AND RATIOS OF EARNINGS TO COMBINED FIXED
                     CHARGES AND PREFERRED STOCK DIVIDENDS
 
  The following table sets forth the Corporation's ratios of earnings to fixed
charges and ratios of earnings to combined fixed charges and preferred stock
dividends for the respective periods indicated:

</TABLE>
- --------
(1) The ratios for the twelve months ended June 30, 1997 include charges
    incurred in connection with the Merger. Had such charges been excluded
    from earnings, the ratio of earnings to fixed charges for such period
    would have been 3.1x, and the ratio of earnings to combined fixed charges
    and preferred stock dividends would have been 2.5x.
(2) As a result of the Merger, each of the Corporation's ratios reflects the
    combined operations of the Corporation and WECo. Because WECo's fiscal
    year ended September 30, the combined ratios for the five years ended
    December 31, 1996 reflect the fiscal years ended December 31 for the
    Corporation and September 30 for WECo. June 30 ratios are comprised of the
    results of the Corporation and WECo for the twelve months ended June 30.
(3) For purposes of computing the ratios of earnings to fixed charges,
    earnings represent income from continuing operations before extraordinary
    items and cumulative effect of changes in accounting principles plus
    applicable income taxes and fixed charges. Fixed charges include all
    interest expense and the proportion deemed representative of the interest
    factor of rent expense.
(4) For purposes of computing the ratio of earnings to combined fixed charges
    and preferred stock dividends, earnings represent income from continuing
    operations before extraordinary items and cumulative effect of changes in
    accounting principles plus applicable income taxes and fixed charges.
    Fixed charges include all interest expense, the proportion deemed
    representative of the interest factor of rent expense and the equivalent
    of pretax preferred dividend requirements.

                      PUGET SOUND ENERGY CAPITAL TRUST I
 
  The Trust is a statutory business trust formed under Delaware law pursuant
to (i) the Trust Agreement executed by the Corporation, as Sponsor, The First
National Bank of Chicago, as Property Trustee, First Chicago Delaware Inc., as
Delaware Trustee, and the Administrative Trustees named therein, and (ii) the
filing of a certificate of trust with the Delaware Secretary of State on June
3, 1997. The Trust exists for the exclusive purposes of (i) issuing and
selling the Trust Securities, (ii) using the proceeds from the sale of Trust
Securities to acquire the Junior Subordinated Debentures and (iii) engaging in
only those other activities incidental thereto. Accordingly, the Junior
Subordinated Debentures will be the sole assets of the Trust, and payments
under the Junior Subordinated Debentures will be the sole revenues of the
Trust. All of the Common Securities will be owned by the Corporation. The
Common Securities will rank pari passu, and payments will be made thereon pro
rata, with the Capital Securities, except that upon the occurrence and
continuance of an event of default under the Trust Agreement, the rights of
the Corporation as holder of the Common Securities to payments in respect of
Distributions and payments upon liquidation, redemption or otherwise will be
subordinated to the rights of the holders of the Capital Securities. See
"Description of Exchange Securities--Description of Exchange Capital
Securities--Subordination of Common Securities." The Corporation has acquired
Common Securities in a Liquidation Amount equal to approximately 3% of the
total capital of the Trust. The Trust has a term of 31 years, but may
terminate earlier as provided in the Trust Agreement. The Trust's business and
affairs are conducted by its trustees, each appointed by the Corporation as
holder of the Common Securities. The trustees for the Trust are The First
National Bank of Chicago, as the Property Trustee (the "Property Trustee"),
First Chicago Delaware Inc., as the Delaware Trustee (the "Delaware Trustee"),
and three individual trustees (the "Administrative Trustees") who are
employees or officers of or affiliated with the Corporation (collectively, the
"Issuer Trustees"). The First National Bank of Chicago, as Property Trustee,
will act as sole indenture trustee under the Trust Agreement. First Chicago
Delaware Inc., will also act as indenture trustee under the Guarantee and the
Indenture. See "Description of Exchange Securities--Description of Exchange
Guarantee" and "--Description of Exchange Junior Subordinated Debentures."
 
  The holder of the Common Securities of the Trust or, if an Event of Default
under the Trust Agreement has occurred and is continuing, the holders of a
majority in Liquidation Amount of the Capital Securities, will be entitled to
appoint, remove or replace the Property Trustee and/or the Delaware Trustee.
In no event will the holders of the Capital Securities have the right to vote
to appoint, remove or replace the Administrative Trustees; such voting rights
will be vested exclusively in the holder of the Common Securities. The duties
and obligations of each Issuer Trustee are governed by the Trust Agreement.
The Corporation has and will continue to pay all fees, expenses, debts and
obligations (other than the Trust Securities) related to the Trust and the
offering of the Capital Securities and has and will continue to pay, directly
or indirectly, all ongoing costs, expenses and liabilities of the Trust. The
principal executive office of the Trust is c/o Puget Sound Energy, Inc., 411--

                              THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
  In connection with the sale of the Original Capital Securities, the
Corporation and the Trust entered into the Registration Rights Agreement with
the Initial Purchasers, pursuant to which the Corporation and the Trust agreed
to file and to use their reasonable efforts to cause to become effective with
the Commission a registration statement with respect to the exchange of the
Original Capital Securities for capital securities with terms identical in all
material respects to the terms of the Original Capital Securities. A copy of
the Registration Rights Agreement has been filed as an Exhibit to the
Registration Statement of which this Prospectus is a part.
 
  The Exchange Offer is being made to satisfy the contractual obligations of
the Corporation and the Trust under the Registration Rights Agreement. The
form and terms of the Exchange Capital Securities are the same as the form and
terms of the Original Capital Securities except that the Exchange Capital
Securities have been registered under the Securities Act and will not be
subject to certain restrictions on transfer applicable to the Original Capital
Securities, and will not provide for any increase in the Distribution rate
thereon. In that regard, the Original Capital Securities provide, among other
things, that, if a registration statement relating to the Exchange Offer has
not been filed by November 3, 1997 and declared effective by December 3, 1997,
the Distribution rate borne by the Original Capital Securities will increase
by 0.25% per annum until such registration statement is filed or declared
effective, as the case may be. Upon consummation of the Exchange Offer,
holders of Original Capital Securities will not be entitled to any increase in
the Distribution rate thereon or any further registration rights under the
Registration Rights Agreement, except under limited circumstances. See "Risk
Factors--Consequences of a Failure to Exchange Original Capital Securities"
and "Description of Exchange Securities."
 
  The Exchange Offer is not being made to, nor will the Trust accept tenders
for exchange from, holders of Original Capital Securities in any jurisdiction
in which the Exchange Offer or the acceptance thereof would not be in
compliance with the securities or blue sky laws of such jurisdiction.
 
  Unless the context requires otherwise, the term "holder" with respect to the
Exchange Offer means any person in whose name the Original Capital Securities
are registered on the books of the Trust or any other person who has obtained
a properly completed bond power from the registered holder, or any person
whose Original Capital Securities are held of record by The Depository Trust
Company ("DTC") who desires to deliver such Original Capital Securities by
book-entry transfer at DTC.
 
  Pursuant to the Exchange Offer, the Corporation will exchange as soon as
practicable after the date hereof, the Original Guarantee for the Exchange
Guarantee and the Original Junior Subordinated Debentures, in an amount
corresponding to the Original Capital Securities accepted for exchange, for a
like aggregate principal amount of the Exchange Junior Subordinated
Debentures. The Exchange Guarantee and Exchange Junior Subordinated Debentures
have been registered under the Securities Act.
 
TERMS OF THE EXCHANGE OFFER
 
  The Trust hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $100 million aggregate Liquidation Amount of Exchange Capital
Securities for a like aggregate Liquidation Amount of Original Capital
Securities properly tendered on or prior to the Expiration Date and not
properly withdrawn in accordance with the procedures described below. The
Trust will issue, promptly after the Expiration Date, an aggregate Liquidation
Amount of up to $100 million of Exchange Capital Securities in exchange for a
like principal amount of outstanding Original Capital Securities tendered and
accepted in connection with the Exchange Offer. Holders may tender their
Original Capital Securities in whole or in part in a Liquidation Amount of not
less than $100,000 (100 Capital Securities) or any integral multiple of $1,000
Liquidation Amount (one Capital Security) in excess thereof.
 
 
                                      25
<PAGE>
 
  The Exchange Offer is not conditioned upon any minimum Liquidation Amount of
Original Capital Securities being tendered. As of the date of this Prospectus,
$100 million aggregate Liquidation Amount of the Original Capital Securities
is outstanding.
 
  Holders of Original Capital Securities do not have any appraisal or
dissenters' rights in connection with the Exchange Offer. Original Capital
Securities which are not tendered for or are tendered but not accepted in
connection with the Exchange Offer will remain outstanding and be entitled to
the benefits of the Declaration, but will not be entitled to any further
registration rights under the Registration Rights Agreement, except under
limited circumstances. See "Risk Factors--Consequences of a Failure to
Exchange Original Capital Securities" and "Description of Exchange
Securities."
 
  If any tendered Original Capital Securities are not accepted for exchange
because of an invalid tender, the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Original Capital
Securities will be returned, without expense, to the tendering holder thereof
promptly after the Expiration Date.
 
  Holders who tender Original Capital Securities in connection with the
Exchange Offer will not be required to pay brokerage commissions or fees or,
subject to the instructions in the Letter of Transmittal, transfer taxes with
respect to the exchange of Original Capital Securities in connection with the
Exchange Offer. The Corporation will pay all charges and expenses, other than
certain applicable taxes described below, in connection with the Exchange
Offer. See "--Fees and Expenses."
 
  NEITHER THE CORPORATION, THE BOARD OF DIRECTORS OF THE CORPORATION NOR ANY
ISSUER TRUSTEE OF THE TRUST MAKES ANY RECOMMENDATION TO HOLDERS OF ORIGINAL
CAPITAL SECURITIES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR
ANY PORTION OF THEIR ORIGINAL CAPITAL SECURITIES PURSUANT TO THE EXCHANGE
OFFER. IN ADDITION, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH
RECOMMENDATION. HOLDERS OF ORIGINAL CAPITAL SECURITIES MUST MAKE THEIR OWN
DECISIONS WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO, THE
AGGREGATE AMOUNT OF ORIGINAL CAPITAL SECURITIES TO TENDER BASED ON SUCH
HOLDERS' OWN FINANCIAL POSITIONS AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" means 5:00 p.m., New York City time, on     ,
1997 unless the Exchange Offer is extended by the Corporation or the Trust (in
which case the term "Expiration Date" shall mean the latest date and time to
which the Exchange Offer is extended).
 
  The Corporation and the Trust expressly reserve the right in their sole and
absolute discretion, subject to applicable law, at any time and from time to
time, (i) to delay the acceptance of the Original Capital Securities for
exchange, (ii) to terminate the Exchange Offer (whether or not any Original
Capital Securities have theretofore been accepted for exchange) if the Trust
determines, in its sole and absolute discretion, that any of the events or
conditions referred to in "--Conditions to the Exchange Offer" have occurred
or exist or have not been satisfied, (iii) to extend the Expiration Date of
the Exchange Offer and retain all Original Capital Securities tendered
pursuant to the Exchange Offer, subject, however, to the right of holders of
Original Capital Securities to withdraw their tendered Original Capital
Securities as described under "--Withdrawal Rights," and (iv) to waive any
condition or otherwise amend the terms of the Exchange Offer in any respect.
 
  If the Exchange Offer is amended in a manner determined by the Corporation
and the Trust to constitute a material change, or if the Corporation and the
Trust waive a material condition of the Exchange Offer, the Corporation and
the Trust will promptly disclose such amendment by means of a prospectus
supplement that will be distributed to the holders of the Original Capital
Securities, and the Corporation and the Trust will extend the Exchange Offer
to the extent required by Rule 14e-1 under the Exchange Act.
 
                                      26
<PAGE>
 
  Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and
by making a public announcement thereof, and such announcement in the case of
an extension will be made no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled Expiration Date. Without
limiting the manner in which the Corporation and the Trust may choose to make
any public announcement and subject to applicable law, the Corporation and the
Trust shall have no obligation to publish, advertise or otherwise communicate
any such public announcement other than by issuing a release to an appropriate
news agency.
 
ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF EXCHANGE CAPITAL SECURITIES
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
Trust will exchange Exchange Capital Securities for Original Capital
Securities validly tendered and not withdrawn (pursuant to the withdrawal
rights described in "--Withdrawal Rights") promptly after the Expiration Date.
 
  Subject to the conditions set forth in "--Conditions to the Exchange Offer,"
delivery of Exchange Capital Securities in exchange for Original Capital
Securities tendered and accepted for exchange pursuant to the Exchange Offer
will be made only after timely receipt by the Exchange Agent of (i)
certificates for Original Capital Securities or a book-entry confirmation of a
book-entry transfer of Original Capital Securities into the Exchange Agent's
account at DTC, including an Agent's Message if the tendering holder does not
deliver a Letter of Transmittal, (ii) a completed and signed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees,
or, in the case of a book-entry transfer, an Agent's Message in lieu of the
Letter of Transmittal, and (iii) any other documents required by the Letter of
Transmittal. Accordingly, the delivery of Exchange Capital Securities might
not be made to all tendering holders at the same time, and will depend upon
when certificates for Original Capital Securities, book-entry confirmations
with respect to Original Capital Securities and other required documents are
received by the Exchange Agent.
 
  The term "book-entry confirmation" means a timely confirmation of a book-
entry transfer of Original Capital Securities into the Exchange Agent's
account at DTC. See "--Procedures for Tendering Original Capital Securities--
Book-Entry Transfer." The term "Agent's Message" means a message, transmitted
by DTC to and received by the Exchange Agent and forming a part of a book-
entry confirmation, which states that DTC has received an express
acknowledgment from the tendering participant, which acknowledgment states
that such participant has received and agrees to be bound by the Letter of
Transmittal and that the Trust and the Corporation may enforce such Letter of
Transmittal against such participant.
 
  Subject to the terms and conditions of the Exchange Offer, the Corporation
and the Trust will be deemed to have accepted for exchange, and thereby
exchanged, Original Capital Securities validly tendered and not withdrawn as,
if and when the Trust gives oral or written notice to the Exchange Agent of
the Corporation's and the Trust's acceptance of such Original Capital
Securities for exchange pursuant to the Exchange Offer. The Exchange Agent
will act as agent for the Corporation and the Trust for the purpose of
receiving tenders of Original Capital Securities, Letters of Transmittal and
related documents, and as agent for tendering holders for the purpose of
receiving Original Capital Securities, Letters of Transmittal and related
documents and transmitting Exchange Capital Securities which will not be held
in global form by DTC or a nominee of DTC to validly tendering holders. Such
exchange will be made promptly after the Expiration Date. If for any reason
whatsoever, acceptance for exchange or the exchange of any Original Capital
Securities tendered pursuant to the Exchange Offer is delayed (whether before
or after the Corporation's and the Trust's acceptance for exchange of Original
Capital Securities) or the Corporation and the Trust extend the Exchange Offer
or are unable to accept for exchange or exchange Original Capital Securities
tendered pursuant to the Exchange Offer, then, without prejudice to the
Corporation's and the Trust's rights set forth herein, the Exchange Agent may,
nevertheless, on behalf of the Corporation and the Trust and subject to Rule
14e-1(c) under the Exchange Act, retain tendered Original Capital Securities
and such Original Capital Securities may not be withdrawn except to the extent
tendering holders are entitled to withdrawal rights as described in "--
Withdrawal Rights."
 
 
                                      27
<PAGE>
 
  Pursuant to an Agent's Message or a Letter of Transmittal, a holder of
Original Capital Securities will represent, warrant and agree in the Letter of
Transmittal that it has full power and authority to tender, exchange, sell,
assign and transfer Original Capital Securities, that the Trust will acquire
good, marketable and unencumbered title to the tendered Original Capital
Securities, free and clear of all liens, restrictions, charges and
encumbrances, and the Original Capital Securities tendered for exchange are
not subject to any adverse claims or proxies. The holder also will warrant and
agree that it will, upon request, execute and deliver any additional documents
deemed by the Trust or the Exchange Agent to be necessary or desirable to
complete the exchange, sale, assignment, and transfer of the Original Capital
Securities tendered pursuant to the Exchange Offer.
 
PROCEDURES FOR TENDERING ORIGINAL CAPITAL SECURITIES
 
 Valid Tender
 
  Except as set forth below, in order for Original Capital Securities to be
validly tendered by book-entry transfer, an Agent's Message or a completed and
signed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees, and in either case any other documents required by the
Letter of Transmittal, must be delivered to the Exchange Agent by mail,
facsimile, hand delivery or overnight courier at one of the Exchange Agent's
addresses set forth in "--Exchange Agent" on or prior to the Expiration Date
and either (i) such Original Capital Securities must be tendered pursuant to
the procedures for book-entry transfer set forth below or (ii) the guaranteed
delivery procedures set forth below must be complied with.
 
  Except as set forth below, in order for Original Capital Securities to be
validly tendered by a means other than by book-entry transfer, a completed and
signed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees, and any other documents required by the Letter of
Transmittal must be delivered to the Exchange Agent by mail, facsimile, hand
delivery or overnight courier at one of the Exchange Agent's addresses set
forth in "--Exchange Agent" on or prior to the Expiration Date and either (i)
such Original Capital Securities must be delivered to the Exchange Agent on or
prior to the Expiration Date or (ii) the guaranteed delivery procedures set
forth below must be complied with.
 
  If less than all Original Capital Securities are tendered, a tendering
holder should fill in the amount of Original Capital Securities being tendered
in the appropriate box on the Letter of Transmittal. The entire amount of
Original Capital Securities delivered to the Exchange Agent will be deemed to
have been tendered unless otherwise indicated.
 
  THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. IF DELIVERY IS TO BE BY MAIL, THE USE OF REGISTERED MAIL,
RETURN RECEIPT REQUESTED, PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE
IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE
TIMELY DELIVERY.
 
 Book-Entry Transfer
 
  The Exchange Agent and DTC have confirmed that any Participant (as defined
in "Description of Exchange Securities--Description of Exchange Capital
Securities--Depositary Procedures") in DTC's book-entry transfer facility
system may utilize DTC's ATOP procedures to tender Original Capital
Securities. The Exchange Agent will establish an account with respect to the
Original Capital Securities at DTC for purposes of the Exchange Offer within
two business days after the date of this Prospectus. Any Participant may make
a book-entry delivery of the Original Capital Securities by causing DTC to
transfer such Original Capital Securities into the Exchange Agent's account at
DTC in accordance with DTC's ATOP procedures for transfer. However, although
delivery of Original Capital Securities may be effected through book-entry
transfer into the Exchange Agent's account at
 
                                      28
<PAGE>
 
DTC, an Agent's Message or a completed and signed Letter of Transmittal (or
facsimile thereof), with any required signature guarantees and any other
documents required by the Letter of Transmittal, must in any case be delivered
to and received by the Exchange Agent at one of its addresses set forth in "--
Exchange Agent" on or prior to the Expiration Date, or the guaranteed delivery
procedure set forth below must be complied with.
 
  DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
 Signature Guarantees
 
  Certificates for the Original Capital Securities need not be endorsed and
signature guarantees on the Letter of Transmittal are unnecessary unless (a) a
certificate for the Original Capital Securities is registered in a name other
than that of the person surrendering the certificate or (b) such holder
completes the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" in the Letter of Transmittal. In the case of (a) or (b)
above, such certificates for Original Capital Securities must be duly endorsed
or accompanied by a properly executed bond power, with the endorsement or
signature on the bond power and on the Letter of Transmittal guaranteed by a
firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution," including (as such terms are defined
therein): (i) a bank; (ii) a broker, dealer, municipal securities broker or
dealer or government securities broker or dealer; (iii) a credit union; (iv) a
national securities exchange, registered securities association or clearing
agency; or (v) a savings association that is a participant in a Securities
Transfer Association (an "Eligible Institution"), unless surrendered on behalf
of such Eligible Institution. See Instruction 1 to the Letter of Transmittal.
 
 Guaranteed Delivery
 
  If a holder desires to tender Original Capital Securities pursuant to the
Exchange Offer and the certificates for such Original Capital Securities are
not immediately available or time will not permit all required documents to
reach the Exchange Agent on or prior to the Expiration Date, or the procedure
for book-entry transfer cannot be completed on a timely basis, such Original
Capital Securities may nevertheless be tendered, provided that all of the
following guaranteed delivery procedures are complied with:
 
    (a) such tenders are made by or through an Eligible Institution;
 
    (b) a properly completed and duly executed Notice of Guaranteed Delivery,
  substantially in the form accompanying the Letter of Transmittal, is
  received by the Exchange Agent, as provided below, on or prior to the
  Expiration Date; and
 
    (c) the certificates (or a book-entry confirmation) representing all
  tendered Original Capital Securities, in proper form for transfer, together
  with a properly completed and duly executed Letter of Transmittal (or
  facsimile thereof), with any required signature guarantees and any other
  documents required by the Letter of Transmittal, are received by the
  Exchange Agent within three New York Stock Exchange trading days after the
  date of execution of such Notice of Guaranteed Delivery.
 
  The Notice of Guaranteed Delivery may be delivered by hand, or transmitted
by facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such notice.
 
  Notwithstanding any other provision hereof, the delivery of Exchange Capital
Securities in exchange for Original Capital Securities tendered and accepted
for exchange pursuant to the Exchange Offer will in all cases be made only
after timely receipt by the Exchange Agent of Original Capital Securities, or
of a book-entry confirmation with respect to such Original Capital Securities,
and a properly completed and duly executed Letter of Transmittal (or facsimile
thereof), together with any required signature guarantees and any other
documents required by the Letter of Transmittal. Accordingly, the delivery of
Exchange Capital Securities might not be made to all tendering holders at the
same time, and will depend upon when Original Capital Securities, book-entry
confirmations with respect to Original Capital Securities and other required
documents are received by the Exchange Agent.
 
                                      29
<PAGE>
 
  The Trust's acceptance for exchange of Original Capital Securities tendered
pursuant to any of the procedures described above will constitute a binding
agreement between the tendering holder and the Trust upon the terms and
subject to the conditions of the Exchange Offer.
 
 Determination of Validity
 
  All questions as to the form of documents, validity, eligibility (including
time of receipt) and acceptance for exchange of any tendered Original Capital
Securities will be determined by the Corporation and the Trust, in their sole
discretion, whose determination shall be final and binding on all parties. The
Corporation and the Trust reserve the absolute right, in their sole and
absolute discretion, to reject any and all tenders determined by them not to
be in proper form or the acceptance of which, or exchange for, may, in the
opinion of counsel to the Corporation and the Trust, be unlawful. The
Corporation and the Trust also reserve the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer as set
forth in "--Conditions to the Exchange Offer" or any condition or irregularity
in any tender of Original Capital Securities of any particular holder whether
or not similar conditions or irregularities are waived in the case of other
holders.
 
  The interpretation by the Corporation and the Trust of the terms and
conditions of the Exchange Offer (including the Letter of Transmittal and the
instructions thereto) will be final and binding. No tender of Original Capital
Securities will be deemed to have been validly made until all irregularities
with respect to such tender have been cured or waived. Neither the
Corporation, the Trust, any affiliates or assigns of the Corporation or the
Trust, the Exchange Agent nor any other person shall be under any duty to give
any notification of any irregularities in tenders or incur any liability for
failure to give any such notification.
 
  If any Letter of Transmittal, endorsement, bond power, power of attorney, or
any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and unless waived by the
Corporation and the Trust, proper evidence satisfactory to the Corporation and
the Trust, in their sole discretion, of such person's authority to so act must
be submitted.
 
  A beneficial owner of Original Capital Securities that are held by or
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee or custodian is urged to contact such entity promptly if such
beneficial holder wishes to participate in the Exchange Offer.
 
RESALES OF EXCHANGE CAPITAL SECURITIES
 
  The Trust is making the Exchange Offer for the Exchange Capital Securities
in reliance on the position of the staff of the Division of Corporation
Finance of the Commission as set forth in certain interpretive letters
addressed to third parties in other transactions. However, neither the
Corporation nor the Trust sought its own interpretive letter and there can be
no assurance that the staff of the Division of Corporation Finance of the
Commission would make a similar determination with respect to the Exchange
Offer as it has in such interpretive letters to third parties. Based on these
interpretations by the staff of the Division of Corporation Finance of the
Commission, and subject to the two immediately following sentences, the
Corporation and the Trust believe that Exchange Capital Securities issued
pursuant to this Exchange Offer in exchange for Original Capital Securities
may be offered for resale, resold and otherwise transferred by a holder
thereof (other than a holder who is a broker-dealer) without further
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such Exchange Capital Securities are acquired in
the ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such Exchange Capital Securities. However, any holder of Original Capital
Securities who is an "affiliate" of the Corporation or the Trust or who
intends to participate in the Exchange Offer for the purpose of distributing
Exchange Capital Securities, or any broker-dealer who purchased Original
Capital Securities from the Trust to resell pursuant to Rule 144A or any other
available exemption under the Securities Act, (a) will not be able to rely on
the interpretations of the staff of the Division of Corporation Finance of the
Commission set forth in the above-
 
                                      30
<PAGE>
 
mentioned interpretive letters, (b) will not be permitted or entitled to
tender such Original Capital Securities in the Exchange Offer and (c) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any sale or other transfer of such Original
Capital Securities unless such sale is made pursuant to an exemption from such
requirements. In addition, as described below, if any broker-dealer holds
Original Capital Securities acquired for its own account as a result of
market-making or other trading activities and exchanges such Original Capital
Securities for Exchange Capital Securities, then such broker-dealer must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of such Exchange Capital Securities.
 
  Each holder of Original Capital Securities who wishes to exchange Original
Capital Securities for Exchange Capital Securities in the Exchange Offer will
be required to represent that (i) it is not an "affiliate" of the Corporation
or the Trust, (ii) any Exchange Capital Securities to be received by it are
being acquired in the ordinary course of its business, (iii) it has no
arrangement or understanding with any person to participate in a distribution
(within the meaning of the Securities Act) of such Exchange Capital
Securities, and (iv) if such holder is not a broker-dealer, such holder is not
engaged in, and does not intend to engage in, a distribution (within the
meaning of the Securities Act) of such Exchange Capital Securities. In
addition, the Corporation and the Trust may require such holder, as a
condition to such holder's eligibility to participate in the Exchange Offer,
to furnish to the Corporation and the Trust (or an agent thereof) in writing
information as to the number of "beneficial owners" (within the meaning of
Rule 13d-3 under the Exchange Act) on behalf of whom such holder holds the
Capital Securities to be exchanged in the Exchange Offer. Each broker-dealer
that receives Exchange Capital Securities for its own account pursuant to the
Exchange Offer must acknowledge that it acquired the Original Capital
Securities for its own account as the result of market-making activities or
other trading activities and must agree that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale
of such Exchange Capital Securities. The Letter of Transmittal states that by
so acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. Based on the position taken by the staff of the Division of
Corporation Finance of the Commission in the interpretive letters referred to
above, the Corporation and the Trust believe that Participating Broker-Dealers
who acquired Original Capital Securities for their own accounts as a result of
market-making activities or other trading activities may fulfill their
prospectus delivery requirements with respect to the Exchange Capital
Securities received upon exchange of such Original Capital Securities (other
than Original Capital Securities which represent an unsold allotment from the
initial sale of the Original Capital Securities) with a prospectus meeting the
requirements of the Securities Act, which may be the prospectus prepared for
an exchange offer so long as it contains a description of the plan of
distribution with respect to the resale of such Exchange Capital Securities.
Accordingly, this Prospectus, as it may be amended or supplemented from time
to time, may be used by a Participating Broker-Dealer during the period
referred to below in connection with resales of Exchange Capital Securities
received in exchange for Original Capital Securities where such Original
Capital Securities were acquired by such Participating Broker-Dealer for its
own account as a result of market-making or other trading activities. Subject
to certain provisions set forth in the Registration Rights Agreement, the
Corporation and the Trust have agreed that this Prospectus, as it may be
amended or supplemented from time to time, may be used by a Participating
Broker-Dealer in connection with resales of such Exchange Capital Securities
for a period ending 180 days after the Expiration Date (subject to extension
under certain limited circumstances described below) or, if earlier, when all
such Exchange Capital Securities have been disposed of by such Participating
Broker-Dealer. See "Plan of Distribution."
 
  However, a Participating Broker-Dealer who intends to use this Prospectus in
connection with the resale of Exchange Capital Securities received in exchange
for Original Capital Securities pursuant to the Exchange Offer must notify the
Corporation or the Trust, or cause the Corporation or the Trust to be
notified, on or prior to the Expiration Date, that it is a Participating
Broker-Dealer. Such notice may be given in the space provided for that purpose
in the Letter of Transmittal or may be delivered to the Exchange Agent at one
of the addresses set forth in "--Exchange Agent." Any Participating Broker-
Dealer who is an "affiliate" of the Corporation or the Trust may not rely on
such interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.
 
                                      31
<PAGE>
 
  In that regard, each Participating Broker-Dealer who surrenders Original
Capital Securities pursuant to the Exchange Offer will be deemed to have
agreed, by execution of the Letter of Transmittal, that upon receipt of notice
from the Corporation or the Trust of the occurrence of any event or the
discovery of (i) any fact which makes any statement contained or incorporated
by reference in this Prospectus untrue in any material respect or (ii) any
fact which causes this Prospectus to omit to state a material fact necessary
in order to make the statements contained or incorporated by reference herein,
in light of the circumstances under which they were made, not misleading, or
(iii) of the occurrence of certain other events specified in the Registration
Rights Agreement, such Participating Broker-Dealer will suspend the sale of
Exchange Capital Securities (or the Exchange Guarantee or the Exchange Junior
Subordinated Debentures, as applicable) pursuant to this Prospectus until the
Corporation or the Trust has amended or supplemented this Prospectus to
correct such misstatement or omission and has furnished copies of the amended
or supplemented Prospectus to such Participating Broker-Dealer, or the
Corporation or the Trust has given notice that the sale of the Exchange
Capital Securities (or the Exchange Guarantee or the Exchange Junior
Subordinated Debentures, as applicable) may be resumed, as the case may be. If
the Corporation or the Trust gives such notice to suspend the sale of the
Exchange Capital Securities (or the Exchange Guarantee or the Exchange Junior
Subordinated Debentures, as applicable), it shall extend the 180-day period
referred to above during which Participating Broker-Dealers are entitled to
use this Prospectus in connection with the resale of Exchange Capital
Securities by the number of days during the period from and including the date
of the giving of such notice to and including the date when Participating
Broker-Dealers shall have received copies of the amended or supplemented
Prospectus necessary to permit resales of the Exchange Capital Securities or
to and including the date on which the Corporation or the Trust has given
notice that the sale of Exchange Capital Securities (or the Exchange Guarantee
or the Exchange Junior Subordinated Debentures, as applicable) may be resumed,
as the case may be.
 
WITHDRAWAL RIGHTS
 
  Except as otherwise provided herein, tenders of Original Capital Securities
may be withdrawn at any time on or prior to the Expiration Date. In order for
a withdrawal to be effective a written, telegraphic, telex or facsimile
transmission of such notice of withdrawal must be timely received by the
Exchange Agent at one of its addresses set forth in "--Exchange Agent" on or
prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Original Capital Securities to be
withdrawn, the aggregate principal amount of Original Capital Securities to be
withdrawn, and (if certificates for such Original Capital Securities have been
tendered) the name of the registered holder of the Original Capital Securities
as set forth on the Original Capital Securities, if different from that of the
person who tendered such Original Capital Securities. If Original Capital
Securities have been delivered or otherwise identified to the Exchange Agent,
then, prior to the physical release of such Original Capital Securities, the
tendering holder must submit the serial numbers shown on the particular
Original Capital Securities to be withdrawn and the signature on the notice of
withdrawal must be guaranteed by an Eligible Institution, except in the case
of Original Capital Securities tendered for the account of an Eligible
Institution. If Original Capital Securities have been tendered pursuant to the
procedures for book-entry transfer set forth in "--Procedures for Tendering
Original Capital Securities," the notice of withdrawal must specify the name
and number of the account at DTC to be credited with the withdrawal of
Original Capital Securities, in which case a notice of withdrawal will be
effective if delivered to the Exchange Agent by written, telegraphic, telex or
facsimile transmission. Withdrawals of tenders of Original Capital Securities
may not be rescinded. Original Capital Securities properly withdrawn will not
be deemed validly tendered for purposes of the Exchange Offer, but may be
retendered at any subsequent time on or prior to the Expiration Date by
following any of the procedures described above in "--Procedures for Tendering
Original Capital Securities."
 
  All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Trust, in its
sole discretion, whose determination shall be final and binding on all
parties. Neither the Corporation, the Trust, any affiliates or assigns of the
Corporation or the Trust, the Exchange Agent nor any other person shall be
under any duty to give any notification of any irregularities in any notice of
withdrawal or incur any liability for failure to give any such notification.
Any Original Capital Securities which
 
                                      32
<PAGE>
 
have been tendered but which are withdrawn will be returned to the holder
thereof promptly after withdrawal.
 
DISTRIBUTION ON EXCHANGE CAPITAL SECURITIES
 
  Holders of the Original Capital Securities as of November 15, 1997 will
receive the Distribution to be paid on December 1, 1997. Holders of Original
Capital Securities whose Original Capital Securities are accepted for exchange
will not receive any other Distributions on such Original Capital Securities
and will be deemed to have waived the right to receive any Distributions on
such Original Capital Securities accumulated from and after December 1, 1997.
Accordingly, holders of Exchange Capital Securities as of the record date for
the payment of Distributions on June 1, 1998 will be entitled to receive
Distributions accumulated from and after December 1, 1997.
 
CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provisions of the Exchange Offer, or any extension
of the Exchange Offer, the Corporation and the Trust will not be required to
accept for exchange, or to exchange, any Original Capital Securities for any
Exchange Capital Securities, and, as described below, may terminate the
Exchange Offer (whether or not any Original Capital Securities have
theretofore been accepted for exchange) or may waive any conditions to or
amend the Exchange Offer, if any of the following conditions have occurred or
exists or have not been satisfied:
 
    (a) there shall occur a change in the current interpretation by the staff
  of the Commission which permits the Exchange Capital Securities issued
  pursuant to the Exchange Offer in exchange for Original Capital Securities
  to be offered for resale, resold and otherwise transferred by holders
  thereof (other than broker-dealers and any such holder which is an
  "affiliate" of the Corporation or the Trust within the meaning of Rule 405
  under the Securities Act) without compliance with the registration and
  prospectus delivery provisions of the Securities Act, provided that such
  Exchange Capital Securities are acquired in the ordinary course of such
  holders' business and such holders have no arrangement or understanding
  with any person to participate in the distribution of such Exchange Capital
  Securities; or
 
    (b) any law, statute, rule or regulation shall have been adopted or
  enacted which, in the judgment of the Corporation or the Trust, would
  reasonably be expected to impair its ability to proceed with the Exchange
  Offer; or
 
    (c) a stop order shall have been issued by the Commission or any state
  securities authority suspending the effectiveness of the Registration
  Statement, or proceedings shall have been initiated or, to the knowledge of
  the Corporation or the Trust, threatened for that purpose, or any
  governmental approval has not been obtained, which approval the Corporation
  or the Trust shall, in its sole discretion, deem necessary for the
  consummation of the Exchange Offer as contemplated hereby; or
 
    (d) the Corporation shall receive an opinion of counsel experienced in
  such matters to the effect that there is more than an insubstantial risk
  that consummation of the Exchange Offer would result in interest payable to
  the Trust on the Junior Subordinated Debentures being not deductible by the
  Corporation for United States federal income tax purposes.
 
  If the Corporation or the Trust determines in its sole and absolute
discretion that any of the foregoing events or conditions has occurred or
exists or has not been satisfied, it may, subject to applicable law, terminate
the Exchange Offer (whether or not any Original Capital Securities have
theretofore been accepted for exchange) or may waive any such condition or
otherwise amend the terms of the Exchange Offer in any respect. If such waiver
or amendment constitutes a material change to the Exchange Offer, the
Corporation or the Trust will promptly disclose such waiver or amendment by
means of a prospectus supplement that will be distributed to the registered
holders of the Original Capital Securities and will extend the Exchange Offer
to the extent required by Rule 14e-1 under the Exchange Act.

FEES AND EXPENSES
 
  The Corporation has agreed to pay the Exchange Agent reasonable and
customary fees for its services and will reimburse it for its reasonable out-
of-pocket expenses in connection therewith. The Corporation will also pay
brokerage houses and other custodians, nominees and fiduciaries the reasonable
out-of-pocket expenses incurred by them in forwarding copies of this
Prospectus and related documents to the beneficial owners of Original Capital
Securities, and in handling or tendering for their customers.
 
  Holders who tender their Original Capital Securities for exchange will not
be obligated to pay any transfer taxes in connection therewith. If, however,
Exchange Capital Securities are to be delivered to, or are to be issued in the
name of, any person other than the registered holder of the Original Capital
Securities tendered, or if a transfer tax is imposed for any reason other than
the exchange of Original Capital Securities in connection with the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.
 
  Neither the Corporation nor the Trust will make any payment to brokers,
dealers or other nominees soliciting acceptances of the Exchange Offer.

                      DESCRIPTION OF EXCHANGE SECURITIES
 
  The terms of the Original Securities are identical in all materials respects
to the Exchange Securities, except that (i) the Original Securities have not
been registered under the Securities Act, are subject to certain restrictions
on transfer and are entitled to certain rights under the applicable
Registration Rights Agreement (which rights will terminate upon consummation
of the Exchange Offer, except under limited circumstances), (ii) the Exchange
Capital Securities will not contain the $100,000 minimum Liquidation Amount
transfer restriction and certain other restrictions on transfer applicable to
Original Capital Securities, (iii) the Exchange Capital Securities will not
provide for any increase in the Distribution rate thereon and (iv) the
Exchange Junior Subordinated Debentures will not provide for any increase in
the interest rate thereon. The Original Securities provide that, in the event
that a registration statement relating to the Exchange Offer has not been
filed by November 3, 1997 and been declared effective by December 3, 1997, or,
in certain limited circumstances, in the event a shelf registration statement
with respect to the resale of the Original Capital Securities is not declared
effective by the time required by the Registration Rights Agreement, then
liquidated damages will accrue at the rate of 0.25% per annum on the principal
amount of the Original Junior Subordinated Debentures and Distributions will
accrue at the rate of 0.25% per annum on the Liquidation Amount of the
Original Capital Securities, for the period from the occurrence of such event
until such time as such registration statement has been filed or declared
effective, as the case may be. The Exchange Securities are not, and upon
consummation of the Exchange Offer the Original Securities will not be,
entitled to any such additional interest or Distributions. Accordingly,
holders of Original Capital Securities should review the information set forth
in "Risk Factors--Consequences of a Failure to Exchange Original Capital
Securities" and "Description of Exchange Securities."
 
DESCRIPTION OF EXCHANGE CAPITAL SECURITIES
 
  The Exchange Capital Securities will represent preferred beneficial
interests in the Trust and the holders thereof will be entitled to a
preference over the Common Securities in certain circumstances with respect to
Distributions and amounts payable on redemption of the Trust Securities or
liquidation of the Trust. See "--Subordination of Common Securities." The
Trust Agreement has been qualified under the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"). This summary of certain provisions of the
Exchange Capital Securities, the Common Securities and the Trust Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Trust Agreement, including
the definitions therein of certain terms.
 
 General
 
  The Exchange Capital Securities will be limited to $100 million aggregate
Liquidation Amount at any one time outstanding. The Exchange Capital
Securities will rank pari passu, and payments will be made thereon pro rata,
with the Common Securities except as described in "--Subordination of Common
Securities." Legal title to the Junior Subordinated Debentures will be held by
the Property Trustee in trust for the benefit of the holders of the Trust
Securities. The Exchange Guarantee will not guarantee payment of Distributions
or amounts payable on redemption of the Exchange Capital Securities or
liquidation of the Trust when the Trust does not have funds on hand legally
available for such payments. See "--Description of Exchange Guarantee."
 
 Distributions
 
  Distributions on the Exchange Capital Securities will be cumulative, will
accumulate from December 1, 1997 and will be payable semi-annually in arrears
on June 1 and December 1 of each year, commencing June 1, 1998, at the annual
rate of 8.231% of the Liquidation Amount to the holders of record of the
Exchange Capital Securities on the May 15 or November 15 immediately preceding
such date. The amount of Distributions payable for any period will be computed
on the basis of a 360-day year of twelve 30-day months. In the event that any
date on which Distributions are payable on the Exchange Capital Securities is
not a Business Day (as defined below), 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 to any such delay), in each
case with the
 
                                      35
<PAGE>
 
same force and effect as if made on such date (each date on which
Distributions are payable in accordance with the foregoing, a "Distribution
Date"). A "Business Day" shall mean any day other than a Saturday or a Sunday,
or a day on which banking institutions in The City of New York are authorized
or required by law or executive order to remain closed.
 
  So long as no Debenture Event of Default shall have occurred and be
continuing, the Corporation will have the right under the Indenture to defer
the payment of interest on the Exchange Junior Subordinated Debentures at any
time or from time to time for a period not exceeding 10 consecutive semi-
annual periods with respect to each Extension Period, provided that no
Extension Period may extend beyond the Stated Maturity Date. Upon any such
election, semi-annual Distributions on the Exchange Capital Securities will be
deferred by the Trust during any such Extension Period. Distributions to which
holders of the Exchange Capital Securities are entitled during any such
Extension Period will accumulate additional Distributions thereon at the rate
per annum of 8.231% thereof, compounded semi-annually from the relevant
Distribution Date. The term "Distributions," as used herein, shall include any
such additional Distributions.
 
  Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive semi-annual periods or to
extend beyond the Stated Maturity Date. Upon the termination of any such
Extension Period and the payment of all amounts then due, and subject to the
foregoing limitations, the Corporation may elect to begin a new Extension
Period. The Corporation must give the Property Trustee, the Administrative
Trustees and the Debenture Trustee notice of its election of any such
Extension Period at least five Business Days prior to the earlier of (i) the
date the Distributions on the Exchange Capital Securities would have been
payable except for the election to begin such Extension Period or (ii) the
date the Administrative Trustees are required to give notice to any securities
exchange or to holders of such Exchange Capital Securities of the record date
or the date such Distributions are payable but in any event not less than five
Business Days prior to such record date. There is no limitation on the number
of times that the Corporation may elect to begin an Extension Period. See "--
Description of Exchange Junior Subordinated Debentures--Option to Extend
Interest Payment Date" and "Certain Federal Income Tax Consequences--Interest
Income and Original Issue Discount."
 
  During any such Extension Period, the Corporation may not (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock
(which includes common and preferred stock) or (ii) make any payment of
principal of or premium, if any, or interest on or repay, repurchase or redeem
any debt securities of the Corporation (including Other Debentures) that rank
pari passu with or junior in right of payment to the Exchange Junior
Subordinated Debentures or (iii) make any guarantee payments with respect to
any guarantee by the Corporation of the debt securities of any subsidiary of
the Corporation (including Other Guarantees) if such guarantee ranks pari
passu with or junior in right of payment to the Exchange Junior Subordinated
Debentures (other than (a) dividends or distributions in shares of, or
options, warrants or rights to subscribe for or purchase shares of, common
stock of the Corporation, (b) any declaration of a dividend in connection with
the implementation of a shareholders' rights plan, or the issuance of stock
under any such plan in the future, or the redemption or repurchase of any such
rights pursuant thereto, (c) payments under the Guarantee, (d) the purchase of
fractional shares resulting from a reclassification of the Corporation's
capital stock or the exchange or conversion of one class, or series of the
Corporation's capital stock for another class or series of the Corporation's
capital stock, and (e) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions
of such capital stock or the security being converted or exchanged).
 
  Although the Corporation has the right in the future to exercise its option
to defer payments of interest on the Exchange Junior Subordinated Debentures,
the Corporation has no current intention to defer payments of interest on such
Exchange Junior Subordinated Debentures.
 
  The revenue of the Trust available for distribution to holders of the
Capital Securities will be limited to payments under the Junior Subordinated
Debentures in which the Trust has invested the proceeds from the issuance and
sale of the Trust Securities. See "--Description of Exchange Junior
Subordinated
 
                                      36
<PAGE>
 
Debentures--General." If the Corporation does not make interest payments on
the Junior Subordinated Debentures, the Property Trustee will not have funds
available to pay Distributions on the Capital Securities. The payment of
Distributions (if and to the extent the Trust has funds on hand legally
available for the payment of such Distributions) will be guaranteed by the
Corporation on a limited basis as set forth in "--Description of Exchange
Guarantee."
 
 Redemption
 
  Upon the repayment on the Stated Maturity Date or prepayment prior to the
Stated Maturity Date of the Junior Subordinated Debentures, the proceeds from
such repayment or prepayment shall be applied by the Property Trustee to
redeem a Like Amount (as defined below) of the Trust Securities, upon not less
than 30 nor more than 60 days' notice of a date of redemption (the "Redemption
Date"), at the applicable Redemption Price, which shall be equal to (i) in the
case of the repayment of the Junior Subordinated Debentures on the Stated
Maturity Date, the Maturity Redemption Price (equal to the principal of, and
accrued interest on, the Junior Subordinated Debentures), (ii) in the case of
the optional prepayment of the Junior Subordinated Debentures prior to June 1,
2007 upon the occurrence and continuation of a Tax Event, the Tax Event
Redemption Price (equal to the Tax Event Prepayment Price in respect of the
Junior Subordinated Debentures) and (iii) in the case of the optional
prepayment of the Junior Subordinated Debentures on or after June 1, 2007, the
Optional Redemption Price (equal to the Optional Prepayment Price in respect
of the Junior Subordinated Debentures). See "--Description of Exchange Junior
Subordinated Debentures--Optional Prepayment" and "--Tax Event Prepayment."
 
  "Like Amount" means (i) with respect to a redemption of the Trust
Securities, Trust Securities having a Liquidation Amount equal to the
principal amount of Junior Subordinated Debentures to be paid in accordance
with their terms and (ii) with respect to a distribution of Junior
Subordinated Debentures upon the liquidation of the Trust, Junior Subordinated
Debentures having a principal amount equal to the Liquidation Amount of the
Trust Securities of the holder to whom such Junior Subordinated Debentures are
distributed.
 
 Redemption Procedures
 
  If applicable, Trust Securities shall be redeemed at the applicable
Redemption Price with the proceeds from the contemporaneous payment of the
Exchange Junior Subordinated Debentures. Any redemption of Trust Securities
shall be made and the applicable Redemption Price shall be payable on the
Redemption Date only to the extent that the Trust has funds legally available
for the payment of such applicable Redemption Price.
 
  If the Trust gives a notice of redemption in respect of the Exchange Capital
Securities, then, by 12:00 noon, New York City time, on the Redemption Date,
to the extent funds are legally available, with respect to the Exchange
Capital Securities held by DTC or its nominees, the Property Trustee will
deposit irrevocably with DTC funds sufficient to pay the applicable Redemption
Price. See "--Form, Denomination, Book-Entry Procedures and Transfer." With
respect to the Exchange Capital Securities held in certificated form, the
Property Trustee, to the extent funds are legally available, will irrevocably
deposit with the paying agent for the Exchange Capital Securities funds
sufficient to pay the applicable Redemption Price and will give such paying
agent irrevocable instructions and authority to pay the applicable Redemption
Price to the holders thereof upon surrender of their certificates evidencing
the Exchange Capital Securities. See "--Payment and Paying Agency."
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date shall be payable to the holders of such Exchange Capital
Securities on the relevant record dates for the related Distribution Dates. If
notice of redemption shall have been given and funds deposited as required,
then upon the date of such deposit, all rights of the holders of the Exchange
Capital Securities will cease, except the right of the holders of the Exchange
Capital Securities to receive the applicable Redemption Price, but without
interest on such Redemption Price, and the Exchange Capital Securities will
cease to be outstanding. In the event that any Redemption Date of Exchange
Capital Securities is not a Business Day, then the applicable Redemption Price
payable on such date will be paid 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
 
                                      37
<PAGE>
 
will be made on the immediately preceding Business Day. In the event that
payment of the applicable Redemption Price is improperly withheld or refused
and not paid either by the Trust or by the Corporation pursuant to the
Exchange Guarantee as described in "--Description of Exchange Guarantee,"
Distributions on Exchange Capital Securities will continue to accumulate at
the then applicable rate, from the Redemption Date originally established by
the Trust to the date such applicable Redemption Price is actually paid, in
which case the actual payment date will be the Redemption Date for purposes of
calculating the applicable Redemption Price.
 
  Subject to applicable law (including, without limitation, United States
federal securities law), the Corporation or its subsidiaries may at any time
and from time to time purchase outstanding Capital Securities by tender, in
the open market or by private agreement.
 
  Notice of any redemption will be mailed at least 30 days but not more than
60 days prior to the Redemption Date to each holder of Trust Securities at its
registered address. Unless the Corporation defaults in payment of the
applicable Redemption Price on, or in the repayment of, the Junior
Subordinated Debentures, on and after the Redemption Date, Distributions will
cease to accrue on the Trust Securities called for redemption.
 
 Liquidation of the Trust and Distribution of Junior Subordinated Debentures
 
  The Corporation will have the right at any time to terminate the Trust and
cause the Junior Subordinated Debentures to be distributed to the holders of
the Trust Securities in liquidation of the Trust. Such right is subject to the
Corporation having received an opinion of counsel to the effect that such
distribution will not be a taxable event to holders of Capital Securities.
 
  The Trust shall automatically terminate upon the first to occur of: (i)
certain events of bankruptcy, dissolution or liquidation of the Corporation;
(ii) the distribution of a Like Amount of the Junior Subordinated Debentures
to the holders of the Trust Securities, if the Corporation, as Sponsor, has
given written direction to the Property Trustee to terminate the Trust (which
direction and distribution is optional and, except as described above, wholly
within the discretion of the Corporation, as Depositor); (iii) redemption of
all of the Trust Securities as described in "--Redemption"; (iv) expiration of
the term of the Trust; or (v) the entry of an order for the dissolution of the
Trust by a court of competent jurisdiction.
 
  If a termination occurs as described in clause (i), (ii), (iv), or (v)
above, the Trust shall be liquidated by the Issuer Trustees as expeditiously
as the Issuer Trustees determine to be possible by distributing, after
satisfaction of liabilities to creditors of the Trust as provided by
applicable law, to the holders of the Trust Securities a Like Amount of the
Junior Subordinated Debentures, unless such distribution is determined by the
Property Trustee not to be practicable, in which event such holders will be
entitled to receive out of the assets of the Trust legally available for
distribution to holders, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, an amount equal to the aggregate of the
Liquidation Amount plus accumulated and unpaid Distributions thereon to the
date of payment (such amount being the "Liquidation Distribution"). If such
Liquidation Distribution can be paid only in part because the Trust has
insufficient assets on hand legally available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by the Trust on
the Capital Securities and the Common Securities shall be paid on a pro rata
basis, except that if a Debenture Event of Default has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities. See "--Subordination of Common Securities."
 
  After the liquidation date is fixed for any distribution of Junior
Subordinated Debentures to holders of the Trust Securities, (i) the Trust
Securities will no longer be deemed to be outstanding, (ii) each registered
global certificate, if any, representing Trust Securities and held by DTC or
its nominee will receive a registered global certificate or certificates
representing the Junior Subordinated Debentures to be delivered upon such
distribution and (iii) any certificates representing Trust Securities not held
by DTC or its nominee will be deemed to represent Junior Subordinated
Debentures having a principal amount equal to the Liquidation Amount of such
Trust Securities, and bearing accrued and unpaid interest in an amount equal
to the accumulated and unpaid
 
                                      38
<PAGE>
 
Distributions on such Trust Securities until such certificates are presented
to the Administrative Trustees or their agent for cancellation, whereupon the
Corporation will issue to such holder, and the Debenture Trustee will
authenticate, a certificate representing such Junior Subordinated Debentures.
 
  There can be no assurance as to the market prices for the Capital Securities
or the Junior Subordinated Debentures that may be distributed in exchange for
the Trust Securities if a dissolution and liquidation of the Trust were to
occur. Accordingly, the Capital 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 Capital Securities offered hereby.
 
 Subordination of Common Securities
 
  Payment of Distributions on, and the Redemption Price of, the Capital
Securities and Common Securities, as applicable, shall be made pro rata based
on the Liquidation Amount of the Trust Securities; provided, however, that if
on any Distribution Date or Redemption Date an Event of Default shall have
occurred and be continuing, no payment of any Distribution on, or applicable
Redemption Price of, any of the Common Securities, and no other payment on
account of the redemption, liquidation or other acquisition of the Common
Securities, shall be made unless payment in full in cash of all accumulated
and unpaid Distributions on all of the outstanding Capital Securities for all
Distribution periods terminating on or prior thereto, or in the case of
payment of the applicable Redemption Price the full amount of such Redemption
Price, shall have been made or provided for, and all funds available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions on, or Redemption Price of, the Capital Securities then due and
payable.
 
  In the case of any Event of Default, the Corporation as holder of the Common
Securities will be deemed to have waived any right to act with respect to such
Event of Default until the effect of such Event of Default shall have been
cured, waived or otherwise eliminated. Until any such Event of Default has
been so cured, waived or otherwise eliminated, the Property Trustee shall act
solely on behalf of the holders of the Capital Securities and not on behalf of
the Corporation as holder of the Common Securities, and only the holders of
the Capital Securities will have the right to direct the Property Trustee to
act on their behalf.
 
 Events of Default; Notice
 
  The occurrence of a Debenture Event of Default (see "--Description of
Exchange Junior Subordinated Debentures--Debenture Events of Default")
constitutes an "Event of Default" under the Trust Agreement.
 
  Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Event of Default to the holders of the Capital Securities, the
Administrative Trustees and the Corporation, as Sponsor, unless such Event of
Default shall have been cured or waived. The Corporation, as Sponsor, and the
Administrative Trustees are required to file annually with the Property
Trustee a certificate as to whether or not they are in compliance with all the
conditions and covenants applicable to them under the Trust Agreement.
 
  If a Debenture Event of Default has occurred and is continuing, the Capital
Securities shall have a preference over the Common Securities as described in
"--Liquidation of the Trust and Distribution of Junior Subordinated
Debentures" and "--Subordination of Common Securities."
 
 Removal of Issuer Trustees
 
  Unless a Debenture Event of Default shall have occurred and be continuing,
any Issuer Trustee may be removed at any time by the holder of the Common
Securities. If a Debenture Event of Default has occurred and is continuing,
the Property Trustee and the Delaware Trustee may be removed at such time by
the holders of a majority in Liquidation Amount of the outstanding Capital
Securities. In no event will the holders of the Capital Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Corporation as the holder of the
Common Securities. No resignation or removal of
 
                                      39
<PAGE>
 
an Issuer Trustee and no appointment of a successor trustee shall be effective
until the acceptance of appointment by the successor trustee in accordance
with the provisions of the Trust Agreement.
 
 Merger or Consolidation of Issuer Trustees
 
  Any corporation into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Issuer Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of such Issuer Trustee, shall be the successor of such Issuer
Trustee under the Trust Agreement, provided such corporation shall be
otherwise qualified and eligible.
 
 Mergers, Consolidations, Amalgamations or Replacements of the Trust
 
  The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to any corporation or other Person,
except as described below. The Trust may, at the request of the Corporation,
as Sponsor, with the consent of the Administrative Trustees but without the
consent of the holders of the Capital Securities, merge with or into,
consolidate, amalgamate, or be replaced by or convey, transfer or lease its
properties and assets as an entirety or substantially as an entirety to a
trust organized as such under the laws of any State; provided, that (i) such
successor entity either (a) expressly assumes all of the obligations of the
Trust with respect to the Capital Securities or (b) substitutes for the
Capital Securities other securities having substantially the same terms as the
Capital Securities (the "Successor Securities") so long as the Successor
Securities rank the same as the Capital Securities rank in priority with
respect to distributions and payments upon liquidation, redemption and
otherwise, (ii) the Corporation expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee with
respect to the Junior Subordinated Debentures, (iii) the Successor Securities
are listed, or any Successor Securities will be listed upon notification of
issuance, on any national securities exchange or other organization on which
the Capital Securities are then listed, if any, (iv) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does
not cause the Capital Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
holders of the Capital Securities (including any Successor Securities) in any
material respect, (vi) such successor entity has a purpose identical to that
of the Trust, (vii) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Corporation has received an
opinion from independent counsel to the Trust experienced in such matters to
the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Capital Securities (including
any Successor Securities) in any material respect, and (b) following such
merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease, neither the Trust nor such successor entity will be required to
register as an investment company under the Investment Company Act of 1940, as
amended (the "Investment Company Act"), and (viii) the Corporation or any
permitted successor or assignee owns all of the common securities of such
successor entity and guarantees the obligations of such successor entity under
the Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in Liquidation Amount of the Trust Securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets as an entirety or substantially as an entirety to
any other entity or permit any other entity to consolidate, amalgamate, merge
with or into, or replace it if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Trust or the
successor entity not to be classified as a grantor trust for United States
federal income tax purposes.
 
 Voting Rights; Amendment of the Trust Agreement
 
  Except as provided below and in "--Mergers, Consolidations, Amalgamations or
Replacements of the Trust" and "--Description of Exchange Guarantee--
Amendments and Assignment" and as otherwise required by law and the Trust
Agreement, the holders of the Capital Securities will have no voting rights.
 
                                      40
<PAGE>
 
  The Trust Agreement may be amended from time to time by the Corporation, the
Property Trustee and the Administrative Trustees, without the consent of the
holders of the Trust Securities (i) to cure any ambiguity, correct or
supplement any provisions in the Trust Agreement that may be inconsistent with
any other provision, or to make any other provisions with respect to matters
or questions arising under the Trust Agreement, which shall not be
inconsistent with the other provisions of the Trust Agreement, or (ii) to
modify, eliminate or add to any provisions of the Trust Agreement to such
extent as shall be necessary to ensure that the Trust will be classified for
United States federal income tax purposes as a grantor trust at all times that
any Trust Securities are outstanding or to ensure that the Trust will not be
required to register as an "investment company" under the Investment Company
Act; provided, however, that such action shall not adversely affect in any
material respect the interests of the holders of the Trust Securities, and any
amendments of the Trust Agreement shall become effective when notice thereof
is given to the holders of the Trust Securities. The Trust Agreement may be
amended by the Issuer Trustees and the Corporation (i) with the consent of
holders representing a majority (based upon Liquidation Amount) of the
outstanding Trust Securities, and (ii) upon receipt by the Issuer Trustees of
an opinion of counsel to the effect that such amendment or the exercise of any
power granted to the Issuer Trustees in accordance with such amendment will
not affect the Trust's status as a grantor trust for United States federal
income tax purposes or the Trust's exemption from status as an "investment
company" under the Investment Company Act, provided that, without the consent
of each holder of Trust Securities, the Trust Agreement may not be amended to
(i) change the amount or timing of any Distribution on the Trust Securities or
otherwise adversely affect the amount of any Distribution required to be made
in respect of the Trust Securities as of a specified date or (ii) restrict the
right of a holder of Trust Securities to institute suit for the enforcement of
any such payment on or after such date. The Exchange Capital Securities and
any Original Capital Securities which remain outstanding after consummation of
the Exchange Offer will vote together as a single class for purposes of
determining whether holders of the requisite percentage in outstanding
Liquidation Amount thereof have taken certain actions or exercised certain
rights under the Trust Agreement.
 
  So long as any Junior Subordinated Debentures are held by the Property
Trustee, the Issuer Trustees shall not (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on such Property Trustee
with respect to the Junior Subordinated Debentures, (ii) waive certain past
defaults under the Indenture, (iii) exercise any right to rescind or annul a
declaration of acceleration of the maturity of the principal of the Junior
Subordinated Debentures or (iv) consent to any amendment, modification or
termination of the Indenture or the Junior Subordinated Debentures, where such
consent shall be required, without, in each case, obtaining the prior approval
of the holders of a majority in Liquidation Amount of all outstanding Capital
Securities; provided, however, that where a consent under the Indenture would
require the consent of each holder of Junior Subordinated Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior approval of each holder of the Capital Securities. The Issuer Trustees
shall not revoke any action previously authorized or approved by a vote of the
holders of the Capital Securities except by subsequent vote of such holders.
The Property Trustee shall notify each holder of Capital Securities of any
notice of default with respect to the Junior Subordinated Debentures. In
addition to obtaining the foregoing approvals of such holders of the Capital
Securities, prior to taking any of the foregoing actions, the Issuer Trustees
shall obtain an opinion of counsel experienced in such matters to the effect
that the Trust will not be classified as an association taxable as a
corporation for United States federal income tax purposes on account of such
action.
 
  Any required approval of holders of Exchange Capital Securities may be given
at a meeting of such holders convened for such purpose or pursuant to written
consent. The Property Trustee will cause a notice of any meeting at which
holders of Exchange Capital Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be
given to each holder of record of Exchange Capital Securities in the manner
set forth in the Trust Agreement.
 
  No vote or consent of the holders of Capital Securities will be required for
the Trust to redeem and cancel the Capital Securities in accordance with the
Trust Agreement.

  Notwithstanding that holders of the Capital Securities are entitled to vote
or consent under any of the circumstances described above, any of the Capital
Securities that are owned by the Corporation, the Issuer Trustees or any
affiliate of the Corporation or any Issuer Trustees, shall, for purposes of
such vote or consent, be treated as if they were not outstanding.
 
 Form, Denomination, Book-Entry Procedures and Transfer
 
  The Exchange Capital Securities initially will be represented by one or more
Capital Securities in registered, global form (collectively, the "Global
Capital Securities"). The Global Capital Securities will be deposited upon
issuance with the Property Trustee as custodian for DTC, in New York, New
York, and registered in the name of DTC or its nominee, in each case for
credit to an account of a direct or indirect participant in DTC as described
below.
 
  Except as set forth below, the Global Capital Securities may be transferred,
in whole and not in part, only to another nominee of DTC or to a successor of
DTC or its nominee, and such transfer shall be effective only when reflected
in the securities register maintained by or on behalf of the Trust. Beneficial
interests in the Global Capital Securities may not be exchanged for Capital
Securities in certificated form except in the limited circumstances described
below. See "--Exchange of Book-Entry Capital Securities for Certificated
Capital Securities."
 
  Other Capital Securities will be issued only in registered, certificated
(i.e., non-global) form. Other Capital Securities may not be exchanged for
beneficial interests in any Global Capital Securities except in the limited
circumstances described below. See "--Exchange of Certificated Capital
Securities for Book-Entry Capital Securities."
 
 Depositary Procedures
 
  DTC has advised the Trust and the Corporation that DTC is a limited-purpose
trust company created to hold securities for its participating organizations
(collectively, the "Participants") and to facilitate the clearance and
settlement of transactions in those securities between Participants through
electronic book-entry changes in accounts of its Participants. The
Participants include securities brokers and dealers (including the Initial
Purchasers), banks, trust companies, clearing corporations and certain other
organizations. Access to DTC's system is also available to other entities such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a Participant, either directly or indirectly
(collectively, the "Indirect Participants"). Persons who are not Participants
may beneficially own securities held by or on behalf of DTC only through the
Participants or the Indirect Participants. The ownership interest and transfer
of ownership interest of each actual purchaser of each security held by or on
behalf of DTC are recorded on the records of the Participants and Indirect
Participants.
 
  DTC has also advised the Trust and the Corporation that, pursuant to
procedures established by it, (i) upon deposit of the Global Capital
Securities, DTC will credit the accounts of Participants designated by the
Initial Purchasers with portions of the Liquidation Amount of the Global
Capital Securities and (ii) ownership of such interests in the Global Capital
Securities will be shown on, and the transfer of ownership thereof will be
effected only through, records maintained by DTC (with respect to the
Participants) or by the Participants and the Indirect Participants (with
respect to other owners of beneficial interests in the Global Capital
Securities).
 
  Investors in the Global Capital Securities may hold their interests therein
directly through DTC if they are participants in such system, or indirectly
through organizations which are participants in such system. All interests in
a Global Capital Security may be subject to the procedures and requirements of
DTC. The laws of some states require that certain persons take physical
delivery in certificated form of securities that they own. Consequently, the
ability to transfer beneficial interests in a Global Capital Security to such
persons will be limited to that extent. Because DTC can act only on behalf of
Participants, which in turn act on behalf of Indirect Participants and certain
banks, the ability of a person having beneficial interests in a Global Capital
Security to
 
                                      42
<PAGE>
 
pledge such interests to persons or entities that do not participate in the
DTC system, or otherwise take actions in respect of such interests, may be
affected by the lack of a physical certificate evidencing such interests. For
certain other restrictions on the transferability of the Capital Securities,
see "--Exchange of Book-Entry Capital Securities for Certificated Capital
Securities" and "--Exchange of Certificated Capital Securities for Book-Entry
Capital Securities."
 
  Except as described below, owners of interests in the Global Capital
Securities will not have Capital Securities registered in their name, will not
receive physical delivery of Capital Securities in certificated form and will
not be considered the registered owners or holders thereof under the Trust
Agreement for any purpose.
 
  Payments in respect of the Global Capital Security registered in the name of
DTC or its nominee will be payable by the Property Trustee to DTC in its
capacity as the registered holder under the Trust Agreement. Under the terms
of the Trust Agreement, the Property Trustee will treat the persons in whose
names the Capital Securities, including the Global Capital Securities, are
registered as the owners thereof for the purpose of receiving such payments
and for any and all other purposes whatsoever. Consequently, neither the
Property Trustee nor any agent thereof has or will have any responsibility or
liability for (i) any aspect of DTC's records or any Participant's or Indirect
Participant's records relating to or payments made on account of beneficial
ownership interests in the Global Capital Securities, or for maintaining,
supervising or reviewing any of DTC's records or any Participant's or Indirect
Participant's records relating to the beneficial ownership interests in the
Global Capital Securities or (ii) any other matter relating to the actions and
practices of DTC or any of its Participants or Indirect Participants. DTC has
advised the Trust and the Corporation that its current practice, upon receipt
of any payment in respect of securities such as the Capital Securities, is to
credit the accounts of the relevant Participants with the payment on the
payment date, in amounts proportionate to their respective holdings in
Liquidation Amount of beneficial interests in the relevant security as shown
on the records of DTC unless DTC has reason to believe it will not receive
payment on such payment date. Payments by the Participants and the Indirect
Participants to the beneficial owners of Capital Securities will be governed
by standing instructions and customary practices and will be the
responsibility of the Participants or the Indirect Participants and will not
be the responsibility of DTC, the Property Trustee, the Trust or the
Corporation. Neither the Trust or the Corporation nor the Property Trustee
will be liable for any delay by DTC or any of its Participants in identifying
the beneficial owners of the Capital Securities, and the Trust or the
Corporation and the Property Trustee may conclusively rely on and will be
protected in relying on instructions from DTC or its nominee for all purposes.
 
  Secondary market trading activity in interests in the Global Capital
Securities will settle in immediately available funds, subject in all cases to
the rules and procedures of DTC and its participants. Transfers between
Participants in DTC will be effected in accordance with DTC's procedures, and
will be settled in same-day funds.
 
  DTC has advised the Trust and the Corporation that it will take any action
permitted to be taken by a holder of Capital Securities only at the direction
of one or more Participants to whose account with DTC interests in the Global
Capital Securities are credited and only in respect of such portion of the
Liquidation Amount of the Capital Securities as to which such Participant or
Participants has or have given such direction. However, if there is an Event
of Default under the Trust Agreement, DTC reserves the right to exchange the
Global Capital Securities for legended Capital Securities in certificated form
and to distribute such Capital Securities to its Participants.
 
  The information in this section concerning DTC and its book-entry systems
has been obtained from sources that the Trust and the Corporation believe to
be reliable, but neither the Trust nor the Corporation takes responsibility
for the accuracy thereof.
 
  Although DTC has agreed to the foregoing procedures to facilitate transfers
of interest in the Global Capital Securities among participants in DTC, it is
under no obligation to perform or to continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the Trust or the
Corporation nor the Property Trustee will have any responsibility for the
performance by DTC or its participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.

 Exchange of Book-Entry Capital Securities for Certificated Capital Securities
 
  A Global Capital Security is exchangeable for Exchange Capital Securities in
registered certificated form if (i) DTC (x) notifies the Trust that it is
unwilling or unable to continue as Depositary for the Global Capital Security
and the Trust thereupon fails to appoint a successor Depositary within 90 days
or (y) has ceased to be a clearing agency registered under the Exchange Act,
(ii) the Corporation in its sole discretion elects to cause the issuance of
the Exchange Capital Securities in certificated form or (iii) there shall have
occurred and be continuing an Event of Default or any event which after notice
or lapse of time or both would be an Event of Default under the Trust
Agreement. In all cases, certificated Capital Securities delivered in exchange
for any Global Capital Security or beneficial interests therein will be
registered in the names, and issued in any approved denominations, requested
by or on behalf of the Depositary (in accordance with its customary
procedures).
 
 Exchange of Certificated Capital Securities for Book-Entry Capital Securities
 
  Other Capital Securities, which will be issued in certificated form, may not
be exchanged for beneficial interests in any Global Capital Security unless
such exchange occurs in connection with a transfer of such Other Capital
Securities and the transferor first delivers to the Property Trustee a written
certificate (in the form provided in the Trust Agreement) to the effect that
such transfer will comply with the appropriate transfer restrictions
applicable to such Capital Securities.
 
 Payment and Paying Agency
 
  Payments in respect of the Exchange Capital Securities held in global form
shall be made to the Depositary, which shall credit the relevant accounts at
the Depositary on the applicable Distribution Dates or in respect of the
Exchange Capital Securities that are not held by the Depositary, such payments
shall be made by check mailed to the address of the holder entitled thereto as
such address shall appear on the register. The paying agent (the "Paying
Agent") shall initially be the Property Trustee and any co-paying agent chosen
by the Property Trustee and acceptable to the Administrative Trustees and the
Corporation. The Paying Agent shall be permitted to resign as Paying Agent
upon 30 days' written notice to the Property Trustee and the Corporation. In
the event that the Property Trustee shall no longer be the Paying Agent, the
Administrative Trustees shall appoint a successor (which shall be a bank or
trust company acceptable to the Administrative Trustees and the Corporation)
to act as Paying Agent.
 
 Restrictions on Transfer
 
  The Exchange Capital Securities will be issued, and may be transferred only,
in minimum denominations of not less than $1,000 and multiples of $1,000 in
excess thereof. Any transfer, sale or other disposition of Exchange Capital
Securities in a denomination of less than $1,000 shall be deemed to be void
and of no legal effect whatsoever. Any such transferee shall be deemed not to
be the holder of such Exchange Capital Securities for any purpose, including
but not limited to the receipt of Distributions on such Exchange Capital
Securities, and such transferee shall be deemed to have no interest whatsoever
in such Exchange Capital Securities.
 
 Registrar and Transfer Agent
 
  The Property Trustee will act as registrar and transfer agent for the
Exchange Capital Securities. Registration of transfers of the Exchange Capital
Securities will be effected without charge by or on behalf of the Trust, but
upon payment of any tax or other governmental charges that may be imposed in
connection with any transfer or exchange. The Trust will not be required to
register or cause to be registered the transfer of the Exchange Capital
Securities after they have been called for redemption.
 
 Information Concerning the Property Trustee
 
  The Property Trustee, other than during the occurrence and continuance of an
Event of Default, undertakes to perform only such duties as are specifically
set forth in the Trust Agreement and, after such Event of Default,
 
                                      44
<PAGE>
 
must exercise the same degree of care and skill as a prudent person would
exercise or use in the conduct of his or her own affairs. Subject to this
provision, the Property Trustee is under no obligation to exercise any of the
powers vested in it by the Trust Agreement at the request of any holder of
Trust Securities unless it is offered reasonable indemnity against the costs,
expenses and liabilities that might be incurred thereby. If no Event of
Default has occurred and is continuing and the Property Trustee is required to
decide between alternative causes of action, construe ambiguous provisions in
the Trust Agreement or is unsure of the application of any provision of the
Trust Agreement, and the matter is not one on which holders of the Capital
Securities or the Common Securities are entitled under the Trust Agreement to
vote, then the Property Trustee shall take such action as is directed by the
Corporation and if not so directed, shall take such action as it deems
advisable and in the best interests of the holders of the Trust Securities and
will have no liability except for its own bad faith, negligence or willful
misconduct.
 
 Miscellaneous
 
  The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Trust in such a way that the Trust will not be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a
corporation for United States federal income tax purposes and so that the
Junior Subordinated Debentures will be treated as indebtedness of the
Corporation for United States federal income tax purposes. In this connection,
the Corporation and the Administrative Trustees are authorized to take any
action, not inconsistent with applicable law, the certificate of trust of the
Trust or the Trust Agreement, that the Corporation and the Administrative
Trustees determine in their discretion to be necessary or desirable for such
purposes, as long as such action does not materially adversely affect the
interests of the holders of the Trust Securities.
 
  Holders of the Trust Securities have no preemptive or similar rights.
 
  The Trust may not borrow money, issue debt, execute mortgages or pledge any
of its assets.
 
DESCRIPTION OF EXCHANGE JUNIOR SUBORDINATED DEBENTURES
 
  The Original Junior Subordinated Debentures were issued and the Exchange
Junior Subordinated Debentures will be issued under an Indenture, as
supplemented from time to time (as so supplemented, the "Indenture"), between
the Corporation and The First National Bank of Chicago, as trustee (the
"Debenture Trustee"). The Indenture has been qualified under the Trust
Indenture Act. This summary of certain terms and provisions of the Exchange
Junior Subordinated Debentures and the Indenture does not purport to be
complete, and where reference is made to particular provisions of the
Indenture, such provisions, including the definitions of certain terms, some
of which are not otherwise defined herein, are qualified in their entirety by
reference to all of the provisions of the Indenture and those terms made a
part of the Indenture by the Trust Indenture Act.
 
 General
 
  Concurrently with the issuance of the Trust Securities, the Trust invested
the proceeds thereof in the Original Junior Subordinated Debentures issued by
the Corporation. The Exchange Junior Subordinated Debentures will bear
interest at the annual rate of 8.231% of the principal amount thereof, payable
semi-annually in arrears on June 1 and December 1 of each year (each, an
"Interest Payment Date"), commencing June 1, 1998, to the person in whose name
each Exchange Junior Subordinated Debenture is registered, subject to certain
exceptions, at the close of business on the May 15 or November 15 immediately
preceding the relevant payment date. It is anticipated that, until the
liquidation, if any, of the Trust, each Exchange Junior Subordinated Debenture
will be held in the name of the Property Trustee in trust for the benefit of
the holders of the Trust Securities. The amount of interest payable for any
period will be computed on the basis of a 360-day year of twelve 30-day
months. In the event that any date on which interest is payable on the
Exchange 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
 
                                      45
<PAGE>
 
such delay) with the same force and effect as if made on the date such payment
was originally payable. Accrued interest that is not paid on the applicable
Interest Payment Date will bear additional interest on the amount thereof (to
the extent permitted by law) at the rate per annum of 8.231% thereof,
compounded semi-annually. The term "interest," as used herein, shall include
semi-annual interest payments, interest on semi-annual interest payments not
paid on the applicable Interest Payment Date and Additional Interest (as
defined below), as applicable.
 
  The Exchange Junior Subordinated Debentures will be issued in denominations
of $1,000 and integral multiples thereof. The Exchange Junior Subordinated
Debentures will mature on June 1, 2027 (the "Stated Maturity Date").
 
  The Exchange Junior Subordinated Debentures will rank pari passu with the
Original Junior Subordinated Debentures and all Other Debentures and will be
unsecured and subordinate and junior in right of payment to the extent and in
the manner set forth in the Indenture to all Senior Indebtedness. See "--
Subordination." The Indenture does not limit the incurrence or issuance of
other secured or unsecured debt of the Corporation, including Senior
Indebtedness. See "--Subordination."
 
 Form, Registration and Transfer
 
  If the Exchange Junior Subordinated Debentures are distributed to the
holders of the Trust Securities, the Exchange Junior Subordinated Debentures
may be represented by one or more global certificates registered in the name
of Cede & Co. as the nominee of DTC. The depositary arrangements for such
Exchange Junior Subordinated Debentures are expected to be substantially
similar to those in effect for the Capital Securities. For a description of
DTC and the terms of the depositary arrangements relating to payments,
transfers, voting rights, redemptions and other notices and other matters, see
"--Description of Exchange Capital Securities--Form, Denomination, Book-Entry
Procedures and Transfer."
 
 Payment and Paying Agents
 
  Payment of principal of (and premium, if any) and any interest on Exchange
Junior Subordinated Debentures will be made at the office of the Debenture
Trustee in The City of New York or at the office of such Paying Agent or
Paying Agents as the Corporation may designate from time to time, except that
at the option of the Corporation payment of any interest may be made except in
the case of Exchange Junior Subordinated Debentures in global form, (i) by
check mailed to the address of the Person entitled thereto as such address
shall appear in the register for Exchange Junior Subordinated Debentures or
(ii) by transfer to an account maintained by the Person entitled thereto as
specified in such register, provided that proper transfer instructions have
been received by the relevant record date. Payment of any interest on any
Exchange Junior Subordinated Debenture will be made to the Person in whose
name such Exchange Junior Subordinated Debenture is registered at the close of
business on the record date for such interest, except in the case of defaulted
interest. The Corporation may at any time designate additional Paying Agents
or rescind the designation of any Paying Agent; however the Corporation will
at all times be required to maintain a Paying Agent in each Place of Payment
for the Exchange Junior Subordinated Debentures.
 
  Any moneys deposited with the Debenture Trustee or any Paying Agent, or then
held by the Corporation in trust, for the payment of the principal of (and
premium, if any) or interest on any Exchange Junior Subordinated Debenture and
remaining unclaimed for two years after such principal (and premium, if any)
or interest has become due and payable shall, at the request of the
Corporation, be repaid to the Corporation and the holder of such Exchange
Junior Subordinated Debenture shall thereafter look, as a general unsecured
creditor, only to the Corporation for payment thereof.
 
 Option to Extend Interest Payment Date
 
  So long as no Debenture Event of Default has occurred and is continuing, the
Corporation will have the right under the Indenture at any time during the
term of the Exchange Junior Subordinated Debentures to defer
 
                                      46
<PAGE>
 
the payment of interest at any time or from time to time for a period not
exceeding 10 consecutive semi-annual periods with respect to each Extension
Period, provided that no Extension Period may extend beyond the Stated
Maturity Date. At the end of such Extension Period, the Corporation must pay
all interest then accrued and unpaid (together with interest thereon at the
annual rate of 8.231%, compounded semi-annually, to the extent permitted by
applicable law). During an Extension Period, interest will continue to accrue
and holders of Exchange Junior Subordinated Debentures (and holders of the
Trust Securities while Trust Securities are outstanding) will be required to
accrue interest income for United States federal income tax purposes prior to
the receipt of cash attributable to such income. See "Certain Federal Income
Tax Consequences--Interest Income and Original Issue Discount."
 
 Option to Extend Interest Payment Date
 
  So long as no Debenture Event of Default has occurred and is continuing, the
Corporation will have the right under the Indenture at any time during the
term of the Junior Subordinated Debentures to defer the payment of interest at
any time or from time to time for a period not exceeding 10 consecutive semi-
annual periods with respect to each Extension Period, provided that no
Extension Period may extend beyond the Stated Maturity Date. At the end of
such Extension Period, the Corporation must pay all interest then accrued and
unpaid (together with interest thereon at the annual rate of 8.231%,
compounded semi-annually, to the extent permitted by applicable law). During
an Extension Period, interest will continue to accrue and holders of Junior
Subordinated Debentures (and holders of the Trust Securities while Trust
Securities are outstanding) will be required to accrue interest income for
United States federal income tax purposes prior to the receipt of cash
attributable to such income. See "Certain Federal Income Tax Consequences--
Interest Income and Original Issue Discount."
 
  During any such Extension Period, the Corporation may not (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock
(which includes common and preferred stock) or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Corporation (including any Other Debentures) that rank
pari passu with or junior in right of payment to the Junior Subordinated
Debentures or (iii) make any guarantee payments with respect to any guarantee
by the Corporation of the debt securities of any subsidiary of the Corporation
(including any Other Guarantees) if such guarantee ranks pari passu with or
junior in right of payment to the Junior Subordinated Debentures (other than
(a) dividends or distributions in shares of or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Corporation, (b) any
declaration of a dividend in connection with the implementation of a
shareholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Guarantee, (d) the purchase of fractional shares
resulting from a reclassification of the Corporation's capital stock or the
exchange or conversion of one class or series of the Corporation's capital
stock for another class or series of the Corporation's capital stock, and (e)
the purchase of fractional interests in shares of the Corporation's capital
stock pursuant to the conversion or exchange provisions of such capital stock
or the security being converted or exchanged).
 
  Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive semi-annual periods or to
extend beyond the Stated Maturity Date. Upon the termination of any such
Extension Period and the payment of all amounts then due on any Interest
Payment Date, the Corporation may elect to begin a new Extension Period,
subject to the above requirements. No interest shall be due and payable during
an Extension Period, except at the end thereof. The Corporation must give the
Property Trustee, the Administrative Trustees and the Debenture Trustee notice
of its election of any Extension Period (or an extension thereof) at least
five Business Days prior to the earlier of (i) the date the Distributions on
the Trust Securities would have been payable except for the election to begin
or extend such Extension Period or (ii) the date the Administrative Trustees
are required to give notice to any securities exchange or to holders of
Capital Securities of the record date or the date such Distributions are
payable, but in any event not less than five Business Days prior to such
record date. The Debenture Trustee shall give notice of the Corporation's
election to begin or extend a new
 
                                      47
<PAGE>
 
Extension Period to the holders of the Capital Securities. There is no
limitation on the number of times that the Corporation may elect to begin an
Extension Period.
 
 Optional Prepayment
 
  The Exchange Junior Subordinated Debentures will be prepayable, in whole or
in part, at the option of the Corporation on or after June 1, 2007, at a
prepayment price (the "Optional Prepayment Price") equal to the percentage of
the outstanding principal amount of the Exchange Junior Subordinated
Debentures specified below, plus, in each case, accrued interest thereon to
the date of prepayment if redeemed during the 12-month period beginning June 1
of the years indicated below:

 Tax Event Prepayment
 
  If a Tax Event shall occur and be continuing, the Corporation may, at its
option, prepay the Junior Subordinated Debentures in whole (but not in part)
at any time prior to June 1, 2007 and within 90 days of the occurrence of such
Tax Event, at a prepayment price (the "Tax Event Prepayment Price") equal to
the greater of (i) 100% of the principal amount of such Junior Subordinated
Debentures or (ii) the sum, as determined by a Quotation Agent, of the present
values of the remaining scheduled payments of principal and interest on the
Junior Subordinated Debentures to the Stated Maturity Date, discounted to the
prepayment date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case,
accrued interest thereon to the date of prepayment.
 
  A "Tax Event" means the receipt by the Corporation and the Trust of an
opinion of counsel experienced in such matters to the effect that, as a result
of any amendment to, or change (including any announced prospective change)
in, the laws or any regulations thereunder of the United States or any
political subdivision or taxing authority thereof or therein, or any amendment
to or change in an interpretation or application of such laws or regulations,
which amendment or change is effective or is announced on or after the Issue
Date, there is more than an insubstantial risk that (i) the Trust would be
subject to United States federal income tax with respect to income received or
accrued on the Junior Subordinated Debentures, (ii) interest payable by the
Corporation on the Junior Subordinated Debentures would not be deductible by
the Corporation, in whole or in part, for United States federal income tax
purposes, or (iii) the Trust would be subject to more than a de minimis amount
of other taxes, duties or other governmental charges.
 
  "Adjusted Treasury Rate" means, with respect to any prepayment date, the
rate per annum equal to (i) the yield, under the heading which represents the
average for the immediately prior week, appearing in the most recently
published statistical release designated "H.15(519)" or any successor
publication which is published weekly by the Federal Reserve and which
established yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption "Treasury Constant
Maturities," for the maturity date corresponding to the Stated Maturity Date
(if no maturity date is within three months before or after the Stated
Maturity Date, yields for the first two published maturities most closely
corresponding to the Stated Maturity
 
                                      48
<PAGE>
 
Date shall be interpolated and the Adjusted Treasury Rate shall be
interpolated or extrapolated from such yields on a straight-line basis,
rounding to the nearest month) or (ii) if such release (or any successor
release) is not published during the week preceding the calculation date or
does not contain such yields, the rate per annum equal to the semi-annual
equivalent yield to maturity of the Comparable Treasury Issue, assuming a
price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such prepayment
date plus, in either case (A) 1.05% if such prepayment date occurs on or prior
to June 1, 1998 and (B) 0.50% in all other cases.
 
  "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity date corresponding to the
Stated Maturity Date that would be utilized at the time of selection and in
accordance with customary financial practice, in pricing new issues of
corporate debt securities with a maturity date corresponding to the Stated
Maturity Date. If no United States Treasury security has a maturity date which
is within three months before or after the Stated Maturity Date, the two most
closely corresponding United States Treasury securities shall be used as the
Comparable Treasury Issue, and the calculation of the Adjusted Treasury Rate
pursuant to clause (ii) of the definition thereof shall be interpolated or
extrapolated on a straight-line basis, rounding to the nearest month.
 
  "Quotation Agent" means the Reference Treasury Dealer appointed by the
Corporation. "Reference Treasury Dealer" means: (i) Smith Barney Inc. and its
successors; provided, however, that if the foregoing shall cease to be a
primary U.S. Government securities dealer in New York City (a "Primary
Treasury Dealer"), the Corporation shall substitute therefor another Primary
Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the
Corporation.
 
  "Comparable Treasury Price" means, with respect to any prepayment date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day preceding such prepayment date, as set forth in the daily
statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for
U.S. Government Securities" or (ii) if such release (or any successor release)
is not published or does not contain such prices on such Business Day, (A) the
average of the Reference Treasury Dealer Quotations for such prepayment date,
after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the Debenture Trustee obtains fewer than three such
Reference Treasury Dealer Quotations, the average of all such Quotations.
 
  "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any prepayment date, the average, as determined by the
Debenture Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted
in writing to the Debenture Trustee by such Reference Treasury Dealer at 5:00
p.m., New York City time, on the third Business Day preceding such prepayment
date.
 
  Notice of any prepayment will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Junior Subordinated
Debentures to be prepaid at its registered address. Unless the Corporation
defaults in payment of the prepayment price, on and after the prepayment date
interest ceases to accrue on such Junior Subordinated Debentures called for
prepayment.
 
  If the Trust is required to pay any additional taxes, duties or other
governmental charges as a result of a Tax Event, the Corporation will pay as
additional amounts on the Junior Subordinated Debentures the Additional Sums.
"Additional Sums" means the additional amounts as may be necessary in order
that the amount available to pay Distributions then due and payable by the
Trust on the outstanding Capital Securities and Common Securities shall not be
reduced as a result of any additional taxes, duties and other governmental
charges to which the Trust has become subject as a result of a Tax Event.

 Restrictions on Certain Payments
 
  The Corporation will also covenant that it will not, (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock
(which includes common and preferred stock) or (ii) make any payment of
principal, interest or premium, if any, on or repay or repurchase or redeem
any debt securities of the Corporation (including Other Debentures) that rank
pari passu with or junior in right of payment to the Junior Subordinated
Debentures or (iii) make any guarantee payments with respect to any guarantee
by the Corporation of the debt securities of any subsidiary of the Corporation
(including under Other Guarantees) if such guarantee ranks pari passu or
junior in right of payment to the Junior Subordinated Debentures (other than
(a) dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Corporation, (b) any
declaration of a dividend in connection with the implementation of a
shareholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto,
(c) payments under the Guarantee, (d) the purchase of fractional shares
resulting from a reclassification of the Corporation's capital stock or the
exchange or conversion of one class or series of the Corporation's capital
stock for another class or series of the Corporation's capital stock and (e)
the purchase of fractional interests in shares of the Corporation's capital
stock pursuant to the conversion or exchange provisions of such capital stock
or the security being converted or exchanged), if at such time (1) there shall
have occurred and be continuing a Declaration Event of Default, (2) there
shall have occurred and be continuing a Debenture Event of Default, (3) there
shall have occurred and be continuing a payment default under the Declaration
or the Indenture, (4) if such Junior Subordinated Debentures are held by the
Trust, the Corporation shall be in default with respect to its payment of any
obligations under the Guarantee or (5) the Corporation shall have given notice
of its election of an Extension Period as provided in the Indenture and shall
not have rescinded such notice, and such Extension Period, or any extension
thereof, shall have commenced.
 
 Modification of Indenture
 
  From time to time the Corporation and the Debenture Trustee may, without the
consent of the holders of Junior Subordinated Debentures, amend, waive or
supplement the Indenture for specified purposes, including, among other
things, curing ambiguities, defects or inconsistencies (provided that any such
action does not materially adversely affect the interest of the holders of
Junior Subordinated Debentures) and qualifying, or maintaining the
qualification of, the Indenture under the Trust Indenture Act. The Indenture
contains provisions permitting the Corporation and the Debenture Trustee, with
the consent of the holders of a majority in principal amount of Junior
Subordinated Debentures, to modify the Indenture in a manner affecting the
rights of the holders of Junior Subordinated Debentures; provided, that no
such modification may, without the consent of the holders of each outstanding
Junior Subordinated Debenture so affected, (i) extend the Stated Maturity
Date, or reduce the principal amount of the Junior Subordinated Debentures or
reduce the rate or extend the time of payment of interest thereon or (ii)
reduce the percentage of principal amount of Junior Subordinated Debentures
the holders of which are required to consent to any such modification of the
Indenture.
 
 Debenture Events of Default
 
  The Indenture provides that any one or more of the following described
events with respect to the Junior Subordinated Debentures constitutes a
"Debenture Event of Default" (whatever the reason for such Debenture Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):
 
    (i) failure for 30 days to pay any interest on the Junior Subordinated
  Debentures or any Other Debentures, when due (subject to the deferral of
  any due date in the case of an Extension Period); or
 
    (ii) failure to pay any principal or premium, if any, on the Junior
  Subordinated Debentures or any Other Debentures when due whether at
  maturity, upon redemption, by declaration of acceleration of maturity or
  otherwise; or
 
 
                                      50
<PAGE>
 
    (iii) failure to observe or perform in any material respect certain other
  covenants contained in the Indenture for 90 days after written notice to
  the Corporation from the Debenture Trustee or the holders of at least 25%
  in aggregate outstanding principal amount of Junior Subordinated
  Debentures; or
 
    (iv) certain events of bankruptcy, insolvency or reorganization of the
  Corporation.
 
  The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee. The Debenture Trustee or the holders of not less than 25% in
aggregate outstanding principal amount of the Junior Subordinated Debentures
may declare the principal due and payable immediately upon a Debenture Event
of Default. The holders of a majority in aggregate outstanding principal
amount of the Junior Subordinated Debentures may annul such declaration and
waive the default if the default (other than the nonpayment of the principal
of the Junior Subordinated Debentures which has become due solely by such
acceleration) has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Debenture Trustee.
 
  The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures affected thereby may, on behalf of the holders
of all the Junior Subordinated Debentures, waive any past default, except a
default in the payment of principal (or premium, if any) on or interest
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest (and premium, if any) and principal due otherwise
than by acceleration has been deposited with the Debenture Trustee) or a
default in respect of a covenant or provision which under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Junior Subordinated Debenture.
 
 Enforcement of Certain Rights by Holders of Capital Securities
 
  If a Debenture Event of Default shall have occurred and be continuing and
shall be attributable to the failure of the Corporation to pay interest (or
premium, if any) on or principal of the Junior Subordinated Debentures on the
due date, a holder of Capital Securities may institute a Direct Action. The
Corporation may not amend the Indenture to remove the foregoing right to bring
a Direct Action without the prior written consent of the holders of all of the
Capital Securities. If the right to bring a Direct Action is removed following
the Exchange Offer, the Trust may become subject to the reporting obligations
under the Exchange Act. Notwithstanding any payments made to a holder of
Capital Securities by the Corporation in connection with a Direct Action, the
Corporation shall remain obligated to pay the principal of (or premium, if
any) or interest on the Junior Subordinated Debentures, and the Corporation
shall be subrogated to the rights of the holder of such Capital Securities
with respect to payments on the Capital Securities to the extent of any
payments made by the Corporation to such holder in any Direct Action.
 
  The holders of the Capital Securities will not be able to exercise directly
any remedies, other than those set forth in the preceding paragraph, available
to the holders of the Junior Subordinated Debentures unless there shall have
been an Event of Default under the Trust Agreement. See "--Description of
Exchange Capital Securities--Events of Default; Notice."
 
 Consolidation, Merger, Sale of Assets and Other Transactions
 
  The Indenture provides that the Corporation shall not consolidate with or
merge into any other Person or convey, transfer or lease its properties and
assets as an entirety or substantially as an entirety to any Person, and no
Person shall consolidate with or merge into the Corporation or convey,
transfer or lease its properties and assets as an entirety or substantially as
an entirety to the Corporation, unless: (i) in case the Corporation
consolidates with or merges into another Person or conveys or transfers its
properties and assets substantially as an entirety to any Person, the
successor Person is organized under the laws of the United States or any State
or the District of Columbia, and such successor Person expressly assumes the
Corporation's obligations on the Junior Subordinated Debentures; (ii)
immediately after giving effect thereto, no Debenture Event of Default, and
 
                                      51
<PAGE>
 
no event which, after notice or lapse of time or both, would become a
Debenture Event of Default, shall have occurred and be continuing; and (iii)
certain other conditions as prescribed in the Indenture are met.
 
  The general provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving the Corporation that may adversely affect holders of the
Junior Subordinated Debentures.
 
 Satisfaction and Discharge
 
  The Indenture provides that when, among other things, all Junior
Subordinated Debentures not previously delivered to the Debenture Trustee for
cancellation (i) have become due and payable or (ii) will become due and
payable at maturity within one year, and the Corporation deposits or causes to
be deposited with the Debenture Trustee funds, in trust, for the purpose and
in an amount sufficient to pay and discharge the entire indebtedness on the
Junior Subordinated Debentures not previously delivered to the Debenture
Trustee for cancellation, for the principal (and premium, if any) and interest
to the date of the deposit or to the Stated Maturity Date, as the case may be,
then the Indenture will cease to be of further effect (except as to the
Corporation's obligations to pay all other sums due pursuant to the Indenture
and to provide the officers' certificates and opinions of counsel described
therein), and the Corporation will be deemed to have satisfied and discharged
the Indenture.
 
 Subordination
 
  The Indenture provides that the Junior Subordinated Debentures issued
thereunder will be subordinate and junior in right of payment to all Senior
Indebtedness. No payment of principal (including redemption payments),
premium, if any, or interest on the Junior Subordinated Debentures may be made
at any time when (i) any Senior Indebtedness is not paid when due, (ii) any
applicable grace period with respect to such default has ended and such
default has not been cured or waived or ceased to exist, or (iii) the maturity
of any Senior Indebtedness has been accelerated because of a default.
 
  Upon any distribution of assets to creditors upon any liquidation,
dissolution, winding up, reorganization, assignment for the benefit of
creditors, marshaling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of the Corporation, all Senior Indebtedness must be paid
in full before the holders of the Junior Subordinated Debentures are entitled
to receive or retain any payment in respect thereof.
 
  In the event of the acceleration of the maturity of Junior Subordinated
Debentures, the holders of all Senior Indebtedness outstanding at the time of
such acceleration will first be entitled to receive payment in full before the
holders of Junior Subordinated Debentures will be entitled to receive or
retain any payment in respect of the Junior Subordinated Debentures.
 
  "Senior Indebtedness" shall mean all Indebtedness for Money Borrowed,
whether outstanding on the date of execution of the Indenture or thereafter
created, assumed or incurred, unless the terms thereof specifically provide
that it is not superior in right of payment to the Junior Subordinated
Debentures, and any deferrals, renewals or extensions of such Senior
Indebtedness.
 
  "Indebtedness for Money Borrowed" shall mean any obligation of, or any
obligation guaranteed by, the Corporation for the repayment of borrowed money,
whether or not evidenced by bonds, debentures, notes or other written
instruments, but shall not include (i) any trade accounts payable in the
ordinary course of business, (ii) any such indebtedness that by its terms
ranks pari passu with or junior in right of payment to the Junior Subordinated
Debentures, (iii) all other debt securities, and guarantees in respect of
those debt securities, issued to any other trust, or a trustee of such trust,
partnership or other entity affiliated with the Corporation that is a
financing vehicle of the Corporation (a "financing entity") in connection with
the issuance by such financing entity of equity securities or other securities
guaranteed by the Corporation pursuant to an instrument that ranks pari passu
with or junior in right of payment to the Guarantee, and (iv) any other
indebtedness that would
 
                                      52
<PAGE>
 
otherwise qualify as "Indebtedness for Money Borrowed" to the extent that such
indebtedness by its terms ranks pari passu with or junior in right of payment
to any of the indebtedness described in (i), (ii) or (iii).
 
  The Indenture places no limitation on the amount of additional Senior
Indebtedness that may be incurred by the Corporation. The Corporation expects
from time to time to incur additional indebtedness constituting Senior
Indebtedness.
 
 Restrictions on Transfer
 
  The Exchange Junior Subordinated Debentures will be issued, and may be
transferred only, in blocks having an aggregate principal amount of not less
than $1,000. Any such transfer of Exchange Junior Subordinated Debentures in a
block having an aggregate principal amount of less than $1,000 shall be deemed
to be void and of no legal effect whatsoever. Any such transferee shall be
deemed not to be the holder of such Exchange Junior Subordinated Debentures
for any purpose, including but not limited to the receipt of payments on such
Exchange Junior Subordinated Debentures, and such transferee shall be deemed
to have no interest whatsoever in such Exchange Junior Subordinated
Debentures.
 
 Governing Law
 
  The Indenture and the Exchange Junior Subordinated Debentures will be
governed by and construed in accordance with the laws of the State of New
York.
 
 Information Concerning the Debenture Trustee
 
  Following the Exchange Offer and the qualification of the Indenture under
the Trust Indenture Act, the Debenture Trustee shall have and be subject to
all the duties and responsibilities specified with respect to an indenture
trustee under the Trust Indenture Act. Subject to such provisions, the
Debenture 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
Debentures, unless offered reasonable indemnity by such holder against the
costs, expenses and liabilities which might be incurred thereby. The Debenture
Trustee is not required to expend or risk its own funds or otherwise incur
personal financial liability in the performance of its duties if the Debenture
Trustee reasonably believes that repayment or adequate indemnity is not
reasonably assured to it.
 
DESCRIPTION OF EXCHANGE GUARANTEE
 
  The Exchange Guarantee will be executed and delivered by the Corporation
concurrently with the issuance by the Trust of the Exchange Capital Securities
for the benefit of the holders from time to time of the Exchange Capital
Securities. The First National Bank of Chicago will act as Guarantee Trustee
under the Exchange Guarantee. The Exchange Guarantee has been qualified under
the Trust Indenture Act. This summary of certain provisions of the Exchange
Guarantee does not purport to be complete and is subject to, and qualified in
its entirety by reference to, all of the provisions of the Exchange Guarantee,
including the definitions therein of certain terms, and the Trust Indenture
Act. The Guarantee Trustee will hold the Exchange Guarantee for the benefit of
the holders of the Exchange Capital Securities.
 
 General
 
  The Corporation will irrevocably agree to pay in full on a subordinated
basis, to the extent set forth herein, the Guarantee Payments (as defined
below) to the holders of the Exchange Capital Securities, as and when due,
regardless of any defense, right of set-off or counterclaim that the Trust may
have or assert other than the defense of payment. The following payments with
respect to the Exchange Capital Securities, to the extent not paid by or on
behalf of the Trust (the "Guarantee Payments"), will be subject to the
Exchange Guarantee: (i) any accumulated and unpaid Distributions required to
be paid on Exchange Capital Securities, to the extent that the Trust has funds
on hand legally available therefor at such time, (ii) the applicable
Redemption Price with respect to Exchange Capital Securities called for
redemption, to the extent that the Trust has funds on hand legally
 
                                      53
<PAGE>
 
available therefor at such time, or (iii) upon a voluntary or involuntary
termination and liquidation of the Trust, the lesser of (a) the Liquidation
Distribution and (b) the amount of assets of the Trust remaining available for
distribution to holders of Exchange Capital Securities. The Corporation's
obligation to make a Guarantee Payment may be satisfied by direct payment of
the required amounts by the Corporation to the holders of the Exchange Capital
Securities or by causing the Trust to pay such amounts to such holders.
 
  The Exchange Guarantee will rank subordinate and junior in right of payment
to all Senior Indebtedness to the extent provided therein. See "--Status of
the Exchange Guarantee." The Exchange Guarantee does not limit the incurrence
or issuance of other secured or unsecured debt of the Corporation, including
Senior Indebtedness, whether under the Indenture, any other indenture that the
Corporation may enter into in the future or otherwise.
 
  The Corporation will, through the Exchange Guarantee, the Trust Agreement,
the Exchange Junior Subordinated Debentures and the Indenture, taken together,
fully, irrevocably and unconditionally guarantee all of the Trust's
obligations under the Exchange Capital Securities.
 
 Status of the Exchange Guarantee
 
  The Exchange Guarantee will constitute an unsecured obligation of the
Corporation and will rank subordinate and junior in right of payment to all
Senior Indebtedness in the same manner as Exchange Junior Subordinated
Debentures.
 
  The Exchange Guarantee will rank pari passu with the Original Guarantee and
all Other Guarantees issued by the Corporation. The Exchange Guarantee will
constitute a guarantee of payment and not of collection (i.e., the guaranteed
party may institute a legal proceeding directly against the Corporation to
enforce its rights under the Exchange Guarantee without first instituting a
legal proceeding against any other person or entity). The Exchange Guarantee
will be held for the benefit of the holders of the Exchange Capital
Securities. The Exchange Guarantee will not be discharged except by payment of
the Guarantee Payments in full to the extent not paid by the Trust or upon
distribution to the holders of the Exchange Capital Securities of the Exchange
Junior Subordinated Debentures. The Exchange Guarantee does not place a
limitation on the amount of additional Senior Indebtedness that may be
incurred by the Corporation. The Corporation expects from time to time to
incur additional indebtedness constituting Senior Indebtedness.
 
 Amendments and Assignment
 
  Except with respect to any changes that do not materially adversely affect
the rights of holders of the Exchange Capital Securities (in which case no
vote will be required), the Exchange Guarantee may not be amended without the
prior approval of the holders of a majority of the Liquidation Amount of such
outstanding Exchange Capital Securities. The manner of obtaining any such
approval will be as set forth in "--Description of Exchange Capital
Securities--Voting Rights; Amendment of the Trust Agreement." All guarantees
and agreements contained in the Guarantee Agreement shall bind the successors,
assigns, receivers, trustees and representatives of the Corporation and shall
inure to the benefit of the holders of the Exchange Capital Securities then
outstanding.
 
 Events of Default
 
  An event of default under the Exchange Guarantee will occur upon the failure
of the Corporation to perform any of its payment or other obligations
thereunder. The holders of a majority in Liquidation Amount of the Exchange
Capital Securities will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Exchange Guarantee or to direct the exercise of any trust or
power conferred upon the Guarantee Trustee under the Exchange Guarantee.
 
  Any holder of the Exchange Capital Securities may institute a legal
proceeding directly against the Corporation to enforce its rights under the
Exchange Guarantee without first instituting a legal proceeding against the
Trust, the Guarantee Trustee or any other person or entity.
 
                                      54
<PAGE>
 
  The Corporation, as guarantor, will be required to file annually with the
Guarantee Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under the
Exchange Guarantee.
 
 Information Concerning the Guarantee Trustee
 
  The Guarantee Trustee, other than during the occurrence and continuance of a
default by the Corporation in performance of the Exchange Guarantee, will
undertake to perform only such duties as are specifically set forth in the
Exchange Guarantee and, after default with respect to the Exchange Guarantee,
must exercise the same degree of care and skill as a prudent person would
exercise or use in the conduct of his or her own affairs. Subject to this
provision, the Guarantee Trustee will be under no obligation to exercise any
of the powers vested in it by the Exchange Guarantee at the request of any
holder of the Exchange Capital Securities unless it is offered reasonable
indemnity against the costs, expenses and liabilities that might be incurred
thereby.
 
 Termination of the Exchange Guarantee
 
  The Exchange Guarantee will terminate and be of no further force and effect
upon full payment of the applicable Redemption Price of the Exchange Capital
Securities, upon full payment of the Liquidation Amount payable upon
liquidation of the Trust or upon distribution of Exchange Junior Subordinated
Debentures to the holders of the Exchange Capital Securities. The Guarantee
will continue to be effective or will be reinstated, as the case may be, if at
any time any holder of the Exchange Capital Securities must restore payment of
any sums paid under the Exchange Capital Securities or the Exchange Guarantee.
 
 Governing Law
 
  The Exchange Guarantee will be governed by and construed in accordance with
the laws of the State of New York.
 
                                      55

            RELATIONSHIP AMONG THE EXCHANGE CAPITAL SECURITIES, THE
      EXCHANGE JUNIOR SUBORDINATED DEBENTURES AND THE EXCHANGE GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
  Payments of Distributions and other amounts due on the Exchange Capital
Securities (to the extent the Trust has funds on hand legally available for
the payment of such Distributions) will be irrevocably guaranteed by the
Corporation as and to the extent set forth in "Description of Exchange
Securities--Description of Exchange Guarantee." Taken together, the
Corporation's obligations under the Exchange Junior Subordinated Debentures,
the Indenture, the Trust Agreement and the Exchange Guarantee will provide, in
the aggregate, a full, irrevocable and unconditional guarantee of payments of
Distributions and other amounts due on the Exchange Capital Securities. No
single document standing alone or operating in conjunction with fewer than all
of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Trust's obligations under the
Exchange Capital Securities. If and to the extent that the Corporation does
not make the required payments on the Exchange Junior Subordinated Debentures,
the Trust will not have sufficient funds to make the related payments,
including Distributions, on the Exchange Capital Securities. The Exchange
Guarantee will not cover any such payment when the Trust does not have
sufficient funds on hand legally available therefor. In such event, the remedy
of a holder of Exchange Capital Securities is to institute a Direct Action.
The obligations of the Corporation under the Exchange Guarantee will be
subordinate and junior in right of payment to all Senior Indebtedness.
 
SUFFICIENCY OF PAYMENTS
 
  As long as payments of interest and other payments are made when due on the
Exchange Junior Subordinated Debentures, such payments will be sufficient to
cover Distributions and other payments due on the Exchange Capital Securities,
primarily because: (i) the aggregate principal amount or Prepayment Price of
the Exchange Junior Subordinated Debentures will be equal to the sum of the
Liquidation Amount or Redemption Price, as applicable, of the Exchange Capital
Securities and Common Securities; (ii) the interest rate and interest and
other payment dates on the Exchange Junior Subordinated Debentures will match
the Distribution rate and Distribution and other payment dates for the Trust
Securities; (iii) the Corporation shall pay for all and any costs, expenses
and liabilities of the Trust except the Trust's obligations to holders of
Trust Securities under such Trust Securities; and (iv) the Trust Agreement
provides that the Trust is not authorized to engage in any activity that is
not consistent with the limited purposes thereof.
 
ENFORCEMENT RIGHTS OF HOLDERS OF EXCHANGE CAPITAL SECURITIES
 
  A holder of any Exchange Capital Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the Exchange
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, the Trust or any other person or entity. A default or event of
default under any Senior Indebtedness would not constitute a default or Event
of Default under the Trust Agreement. However, in the event of payment
defaults under, or acceleration of, Senior Indebtedness, the subordination
provisions of the Indenture will provide that no payments may be made in
respect of the Exchange Junior Subordinated Debentures until such Senior
Indebtedness has been paid in full or any payment default thereunder has been
cured or waived. Failure to make required payments on Exchange Junior
Subordinated Debentures would constitute an Event of Default under the Trust
Agreement.
 
LIMITED PURPOSE OF THE TRUST
 
  The Exchange Capital Securities will represent preferred beneficial
interests in the Trust, and the Trust exists for the sole purpose of issuing
and selling the Trust Securities, using the proceeds from the sale of the
Trust Securities to acquire the Junior Subordinated Debentures and engaging in
only those other activities incidental thereto.
 
                                      56
<PAGE>
 
RIGHTS UPON TERMINATION
 
  Unless the Junior Subordinated Debentures are distributed to holders of the
Trust Securities, upon any voluntary or involuntary termination and
liquidation of the Trust, the holders of the Trust Securities will be entitled
to receive, out of assets held by the Trust, the Liquidation Distribution in
cash. See "Description of Exchange Securities--Description of Exchange Capital
Securities--Liquidation of the Trust and Distribution of Junior Subordinated
Debentures." Upon any voluntary or involuntary liquidation or bankruptcy of
the Corporation, the Property Trustee, as holder of the Exchange Junior
Subordinated Debentures, would be a subordinated creditor of the Corporation,
subordinated in right of payment to all Senior Indebtedness as set forth in
the Indenture, but entitled to receive payment in full of principal (and
premium, if any) and interest, before any stockholders of the Corporation
receive payments or distributions. Since the Corporation will be the guarantor
under the Exchange Guarantee and will agree to pay for all costs, expenses and
liabilities of the Trust (other than the Trust's obligations to the holders of
its Trust Securities), the positions of a holder of Exchange Capital
Securities and a holder of Exchange Junior Subordinated Debentures relative to
other creditors and to stockholders of the Corporation in the event of
liquidation or bankruptcy of the Corporation are expected to be substantially
the same.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
  In the opinion of Perkins Coie, counsel to the Corporation and the Trust
("Tax Counsel"), the following is a summary of certain of the material United
States federal income tax consequences of the exchange of Original Capital
Securities fog Exchange Capital Securities and the ownership and disposition
of Exchange Capital Securities held as capital assets by a holder who
purchased such Original Capital Securities upon initial issuance. It does not
deal with special classes of holders such as banks, thrifts, real estate
investment trusts, regulated investment companies, Non-U.S. Holder's (as
defined below) engaged in a trade or business within the United States,
insurance companies, dealers in securities or currencies, tax-exempt investors
(including pension funds), or persons that will hold the Capital Securities as
a position in a "straddle," as part of a "synthetic security" or "hedge," as
part of a "conversion transaction" or other integrated investment, or as other
than a capital asset. This summary also does not address the tax consequences
to persons that have a functional currency other than the U.S. dollar or the
tax consequences to shareholders, partners or beneficiaries of a holder of
Capital Securities. Further, it does not include any description of any
alternative minimum tax consequences or the tax laws of any state or local
government or of any foreign government that may be applicable to the Capital
Securities. This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations thereunder (the "Regulations") and
the administrative and judicial interpretations thereof, as of the date
hereof, all of which are subject to change, possibly on a retroactive basis.
 
EXCHANGE OF CAPITAL SECURITIES
 
  The exchange of Original Securities for Exchange Securities should not be a
taxable event to holders for United States federal income tax purposes. The
exchange of Original Securities for Exchange Securities pursuant to the
Exchange Offer should not be treated as an "exchange" for United States
federal income tax purposes because the Exchange Securities should not be
considered to differ materially in kind or extent from the Original Securities
and because the exchange will occur by operation of the terms of the Original
Securities. Accordingly, the Exchange Capital Securities should have the same
issue price as the Original Capital Securities, and a holder should have the
same adjusted tax basis and holding period in the Exchange Capital Securities
as the holder had in the Original Capital Securities immediately before the
exchange. Moreover, a holder which had acquired Original Capital Securities
with either market discount or bond premium will be treated as holding
Exchange Capital Securities with the same amount of market discount or bond
premium and will be required to include such market discount in or deduct such
bond premium from their income in the same manner as on the Original Capital
Securities. Holders are urged to consult their tax advisors regarding the
applicability of the market discount and bond premium rules.
 
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
  The Corporation intends to, and by acceptance of an Original Capital
Security each holder covenanted to, treat the Junior Subordinated Debentures
as debt for U.S. federal income tax purposes. In connection with the issuance
of the Original Junior Subordinated Debentures, Tax Counsel rendered its
opinion generally to the effect that, under the law in effect at the time of
issuance of the Original Junior Subordinated Debentures and assuming full
compliance with the terms of the Indenture (and the related documents), and
based on certain facts and assumptions contained in such opinion and certain
representations of the Corporation to Tax Counsel, the Original Junior
Subordinated Debentures will be classified for United States federal income
tax purposes as indebtedness of the Corporation. An opinion of Tax Counsel,
however, is not binding on the Internal Revenue Service (the "IRS") or the
courts. Prospective investors should note that no rulings have been or are
expected to be sought from the IRS with respect to any of these issues and no
assurance can be given that the IRS will not take contrary positions.
Moreover, no assurance can be given that any of the opinions expressed herein
will not be challenged by the IRS or, if challenged, that such a challenge
would not be successful.

CLASSIFICATION OF THE TRUST
 
  In connection with the issuance of the Original Capital Securities, Tax
Counsel rendered its opinion generally to the effect that, under the law then
in effect and assuming full compliance with the terms of the Trust Agreement
and the Indenture (and the related documents), and based on certain facts and
assumptions contained in such opinion, 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, for United States federal
income tax purposes, each holder of Capital Securities (and not the Trust)
generally will be considered the owner of an undivided interest in the Junior
Subordinated Debentures, and each holder will be required to include in its
gross income any interest (or OID accrued) with respect to its allocable share
of those Junior Subordinated Debentures.
 
  Even if the Trust were to be denied grantor trust status, it would not be
treated as a corporation for U.S. federal income tax purposes under the
recently finalized "check-the-box" Regulations, which provide that, if there
is no election to the contrary, a trust that has multiple beneficiaries and
that is treated as a "business entity" will be classified as a partnership for
federal income tax purposes. If the Trust were so characterized, there would
be no material difference in the federal income tax treatment of the holders
(other than possibly the Non-U.S. Holders as described below under "Non-U.S.
Holders")
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
  Under certain Regulations applicable to debt instruments, a "remote"
contingency that stated interest will not be timely paid will be ignored in
determining whether a debt instrument is issued with OID. The Corporation has
represented that the likelihood of its exercising its option to defer payments
of interest is "remote" since exercising that option would prevent the
Corporation from declaring dividends on any class of its equity securities.
Accordingly, the Corporation intends to take the position, based on the advice
of Tax Counsel in reliance on such representation, that the Junior
Subordinated Debentures will not be considered to be issued with OID and,
accordingly, stated interest on the Junior Subordinated Debentures generally
will be taxable to a holder as ordinary income at the time it is paid or
accrued in accordance with such holder's method of accounting.
 
  Under the Regulations, if the Corporation were to exercise its option to
defer payments of interest, the Junior Subordinated Debentures would at that
time be treated as issued with OID, and all stated interest on the Junior
Subordinated Debentures would thereafter be treated as OID as long as the
Junior Subordinated Debentures remain outstanding. In such event, all of a
holder's taxable interest income with respect to the Junior Subordinated
Debentures would thereafter be accounted for on an economic accrual basis
regardless of such holder's method of tax accounting, and actual distributions
of stated interest would not be reported as taxable income. Consequently, a
holder of Capital Securities would be required to include in gross income OID
even though the Corporation would not make actual cash payments during an
Extension Period. Moreover, under the Regulations, if the option to defer the
payment of interest was determined not to be "remote," the Junior Subordinated
Debentures would be treated as having been originally issued with OID. In such
event, all of a holder's taxable interest income with respect to the Junior
Subordinated Debentures would be accounted for on an economic accrual basis
regardless of such holder's method of tax accounting, and actual distributions
of stated interest would not be reported as taxable income.
 
  The Regulations have not yet been addressed in any rulings or other
interpretations by the IRS, and it is possible that the IRS could take a
position contrary to Tax Counsel's interpretation herein.
 
  Because income on the Capital Securities will constitute interest or OID,
corporate holders of the Capital Securities will not be entitled to a
dividends-received deduction with respect to any income recognized with
respect to the Capital Securities.
 
RECEIPT OF JUNIOR SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF THE
TRUST
 
  The Corporation will have the right at any time to liquidate the Trust and
cause the Junior Subordinated Debentures to be distributed to the holders of
the Trust Securities. Under current law, such a distribution, for
 
                                      59
<PAGE>
 
United States federal income tax purposes, would be treated as a nontaxable
event to each holder, and each holder would receive an aggregate tax basis in
the Junior Subordinated Debentures equal to such holder's aggregate tax basis
in its Capital Securities. A holder's holding period in the Junior
Subordinated Debentures so received in liquidation of the Trust would include
the period during which the Capital Securities were held by such holder. If,
however, as a result of a change in law the Trust were characterized for
United States federal income tax purposes as an association taxable as a
corporation at the time of its dissolution, the distribution of the Junior
Subordinated Debentures may constitute a taxable event to holders of Capital
Securities and a holder's holding period in Junior Subordinated Debentures
would begin on the date such Junior Subordinated Debentures were received.
 
  Under certain circumstances described herein (see "Description of Exchange
Securities--Description of Exchange Capital Securities"), the Junior
Subordinated Debentures may be redeemed for cash and the proceeds of such
redemption distributed to holders in redemption of their Capital Securities.
Under current law, such a redemption would, for United States federal income
tax purposes, constitute a taxable disposition of the redeemed Capital
Securities, and a holder could recognize gain or loss as if it sold such
redeemed Capital Securities for cash. See "Sales of Capital Securities."
 
SALES OF CAPITAL SECURITIES
 
  A holder that sells Capital Securities will recognize gain or loss equal to
the difference between its adjusted tax basis in the Capital Securities and
the amount realized on the sale of such Capital Securities (other than with
respect to accrued and unpaid interest, OID, or market discount which has not
yet been included in income, which will be treated as ordinary income). A
holder's adjusted tax basis in the Capital Securities generally will be its
initial purchase price increased by OID (if any) previously includable in such
holder's gross income to the date of disposition and decreased by payments (if
any) received on the Capital Securities in respect of OID. Such gain or loss
generally will be a capital gain or loss and generally will be a long-term
capital gain or loss if the Capital Securities have been held for more than
one year.
 
  The Taxpayer Relief Act of 1997 reduces the maximum rims on long-term
capital gains recognized on capital assets held by individual taxpayers for
more than 18 months as of the date of disposition (and would further reduce
the maximum rates on such gains in the year 2001 and thereafter for certain
individual taxpayers who meet specified conditions) Holders should consult
their own tax advisors concerning these tax law changes.
 
  The Capital Securities may trade at a price that does not accurately reflect
the value of accrued but unpaid interest with respect to the underlying Junior
Subordinated Debentures. A holder who uses the accrual method of accounting
for tax purposes (and a cash method holder, if the Junior Subordinated
Debentures are deemed to have been issued with OID) which disposes of its
Capital 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 (i.e., interest or, possibly, OID), and to add such amount to its
adjusted tax basis in its pro rata share of the underlying Junior Subordinated
Debentures deemed disposed of. To the extent the selling price is less than
the holder's adjusted tax basis (which will include all accrued but unpaid
interest) a holder will recognize a capital loss. Subject to certain limited
exceptions, capital losses cannot be applied to offset ordinary income for
United States federal income tax purposes.
 
PROPOSED TAX LEGISLATION
 
  On February 6, 1997, President's Clinton proposed legislation that, among
other things, would have denied an issuer a deduction for United States
federal income tax purposes for the payment of interest on instruments with
characteristics similar to the Junior Subordinated Debentures. The Taxpayer
Relief Act of 1997, enacted on August 7, 1997, did not contain these
provisions. There can be no assurance, however, that the Proposed Legislation
or similar legislation, if enacted after the date hereof, would not adversely
affect the tax treatment of the Junior Subordinated Debentures or that any
legislation enacted after the date hereof would not cause a Tax Event that may
result in a redemption of the Junior Subordinated Debentures at the Tax Event
Prepayment Price and, consequently, the Trust Securities. See "Description of
Exchange Securities--Description of Exchange

Capital Securities--Redemption" and "Description of Exchange Securities--
Description of Exchange Junior Subordinated Debentures--Tax Event Prepayment."
 
NON-U.S. HOLDERS
 
  For purposes of this discussion, a "Non-U.S. Holder" is any holder that is
not a U.S. Holder for United States federal income tax purposes. A "U.S.
Holder" is a holder of Capital Securities who or which is a citizen or
individual resident (or is treated as a citizen or individual resident) of the
United States for federal income tax purposes, a corporation or partnership
created or organized (or treated as created or organized for federal income
tax purposes) in or under the laws of the United States or any political
subdivision thereof, or a trust or estate the income of which is includable in
its gross income for federal income tax purposes without regard to its source.
For taxable years beginning after December 31, 1996 (or for the immediately
preceding taxable year, if the trustee of a trust so elects), a trust is a
U.S. Holder for federal income tax purposes if, and only if, (i) a court
within the United States is able to exercise primary supervision over the
administration of the trust and (ii) one or more United States trustees have
the authority to control all substantial decisions of the trust.
 
  Under present United States federal income tax laws: (i) payments by the
Trust or any of its paying agents to any holder of a Capital Security who or
which is a Non-U.S. Holder will not be subject to United States federal
withholding tax; provided that, (a) the beneficial owner of the Capital
Security does not actually or constructively own 10 percent or more of the
total combined voting power of all classes of stock of the Corporation
entitled to vote, (b) the beneficial owner of the Capital Security is not a
controlled foreign corporation that is related to the Corporation through
stock ownership, and (c) the beneficial owner of the Capital Securities is not
a bank whose receipt of interest with respect to the Capital Securities (or
the Junior Subordinated Debentures) is described in Section 881(c)(3)(A) of
the Code and (d) either (1) the beneficial owner of the Capital Security
certifies to the Trust or its agent, under penalties of perjury, that it is
not a U.S. Holder and provides its name and address or (2) 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 Capital Security in such capacity,
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 Non-U.S. Holder of a Capital Security
will not be subject to United States federal withholding tax on any gain
realized upon the sale or other disposition of a Capital Security.
 
  If the Trust were to be denied grantor trust status and instead were to be
treated as a trade or business conducted as a partnership for U.S. federal
income tax purposes, it is possible that a Non-U.S. Holder could be subject to
federal income tax (including withholding) with respect to income (including
OID) generated by the Junior Subordinated Debentures.
 
INFORMATION REPORTING TO HOLDERS
 
  Generally, income on the Capital Securities will be reported to holders on
Forms 1099, which forms should be mailed to holders of Capital Securities by
January 31 following each calendar year.
 
BACKUP WITHHOLDING
 
  Payments made on, and proceeds from the sale of, the Capital Securities may
be subject to a "backup" withholding tax of 31% unless the holder complies
with certain identification requirements. Any withheld amounts will be allowed
as a credit against the holder's United States federal income tax, provided
the required information is provided to the IRS.
 
  THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A
HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH

DISPOSITION OF THE CAPITAL SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER
STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES
IN UNITED STATES FEDERAL OR OTHER TAX LAWS.
 
                             ERISA CONSIDERATIONS
 
  ERISA and the Code impose certain restrictions on (a) employee benefit plans
(as defined in Section 3(3) of ERISA) subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), (b) plans (as
defined in Section 4975(e)(1) of the Code) subject to Section 4975 of the
Code, including individual retirement accounts and Keogh Plans, (c) entities
whose underlying assets include plan assets by reason of a plan's investment
in such entities (each of (a), (b) and (c), a "Plan") and (d) persons who have
certain specified relationships to such Plans ("Parties in Interest" under
ERISA and "Disqualified Persons" under the Code). Moreover, based on the
reasoning of the United States Supreme Court in John Hancock Mutual Life
Insurance Co. v. Harris Trust and Savings Bank, 114 S. Ct. 517 (1993), an
insurance company's general account may be deemed to include the assets of the
Plans investing in the general account (e.g., through the purchase of an
annuity contract), and the insurance company might be treated as a Party In
Interest and a Disqualified Person with respect to such Plans by virtue of
such investment. ERISA also imposes certain duties on persons who are
fiduciaries of Plans, and both ERISA and the Code prohibit certain
transactions involving "plan assets" between a Plan and Parties in Interest or
Disqualified Persons with respect to such Plans.
 
  Each of the Corporation (the obligor with respect to the Exchange Junior
Subordinated Debentures held by the Trust), the Property Trustee and the
affiliates of either of them may be considered a Party in Interest or a
Disqualified Person with respect to many Plans. The purchase and/or holding of
Exchange Capital Securities by (or on behalf of) a Plan with respect to which
the Corporation, the Property Trustee or any affiliate of either of them 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 Exchange Capital Securities are acquired
and held pursuant to and in accordance with an applicable exemption, such as
Prohibited Transaction Class Exemption ("PTCE") 84-14 (an exemption for
certain transactions determined by an independent qualified professional asset
manager), PTCE 91-38 (an exemption for certain transactions involving bank
collective investment funds), PTCE 90-1 (an exemption for certain transactions
involving insurance company pooled separate accounts), PTCE 95-60 (an
exemption for transactions involving certain insurance company general
accounts), or PTCE 96-23 (an exemption for certain transactions determined by
an in-house asset manager).
 
  A Plan fiduciary considering the purchase of Exchange Capital Securities
should also be aware that the assets of the Trust may be considered "plan
assets" for ERISA purposes. In such event, service providers with respect to
the assets of the Trust may become Parties in Interest or Disqualified Persons
with respect to investing Plans, and any discretionary authority exercised
with respect to the Junior Subordinated Debentures by such persons could be
deemed to constitute a prohibited transaction under ERISA or the Code. In
order to minimize the likelihood that such prohibited transactions will occur,
each investing Plan (and each person acting on behalf of, or investing with
the assets of, a Plan), by purchasing the Exchange Capital Securities, will be
deemed to have directed the Trust to invest in the Exchange Junior
Subordinated Debentures and to have appointed the Property Trustee. However,
none of the Corporation, the Property Trustee or any affiliate of either of
them can guaranty that such prohibited transactions will not occur.
 
  Any purchaser proposing to acquire Exchange Capital Securities with assets
of any Plan should consult with its legal counsel concerning the impact of
ERISA and the Code and the potential consequences of acquisition and holding
Exchange Capital Securities with respect to their specific circumstances.
Moreover, each Plan
 
                                      62
<PAGE>
 
fiduciary should take into account, among other considerations, whether the
fiduciary has the authority to make the investment; the composition of the
Plan's portfolio with respect to diversification by type of asset; the Plan's
funding objectives; the tax effects of the investment; whether under the
general fiduciary standards of investment prudence and diversification an
investment in the Exchange Capital Securities is appropriate for the Plan,
taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio; and whether the Exchange
Capital Securities will be traded with sufficient regularity to permit such
fiduciary to satisfy ERISA's annual valuation requirement.
 
                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives Exchange Capital Securities for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Capital Securities.
This Prospectus, as it may be amended or supplemented from time to time, may
be used by a broker-dealer in connection with resales of Exchange Capital
Securities received in exchange for Original Capital Securities where such
Original Capital Securities were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Trust and the
Corporation have agreed that, starting on the Expiration Date and ending on
the close of business on the 180th day following the Expiration Date, it will
make this Prospectus, as amended or supplemented, available to any broker-
dealer for use in connection with any such resale. In addition, until       ,
1998, all dealers effecting transactions in the Exchange Securities may be
required to deliver a prospectus.
 
  The Trust and the Corporation will not receive any proceeds from any sale of
Exchange Capital Securities by broker-dealers. Exchange Capital Securities
received by broker-dealers for their own account pursuant to the Exchange
Offer may be sold from time to time in one or more transactions, in the over-
the-counter market, in negotiated transactions, through the writing of options
on the Exchange Capital Securities or a combination of such methods of resale,
at market prices prevailing at the time of resale, at prices related to such
prevailing market prices or at negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such broker-
dealer and/or the purchasers of any such Exchange Capital Securities. Any
broker-dealer that resells Exchange Capital Securities that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such Exchange Capital Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit of any such resale of Exchange Capital Securities and any commissions
or concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that
by acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.
 
  For a period of 180 days after the Expiration Date, the Trust and the
Corporation will promptly send additional copies of this Prospectus and any
amendment or supplement to this Prospectus to any broker-dealer that requests
such documents in the Letter of Transmittal. The Trust and the Corporation
have agreed to pay all expenses incident to the Exchange Offer (including the
expenses of one counsel for the holders of the Capital Securities) other than
commissions or concessions of any brokers or dealers and will indemnify the
holders of the Capital Securities (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.
 
                        VALIDITY OF EXCHANGE SECURITIES
 
  The validity of the Exchange Capital Securities, the Exchange Guarantee and
the Exchange Junior Subordinated Debentures will be passed upon for the
Corporation by Perkins Coie, Seattle, Washington. Certain matters of Delaware
law relating to the validity of the Capital Securities will be passed upon on
behalf of the Trust by Skadden, Arps, Slate, Meagher & Flom LLP, as special
Delaware counsel to the Trust. Certain matters relating to United States
federal income tax considerations will be passed upon for the Corporation by
Perkins Coie.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a court to award, or a corporation's
board of directors to grant, indemnification to directors and officers on
terms sufficiently broad to permit indemnification under certain circumstances
for liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Section 6 of the Corporation's Bylaws (the "Bylaws"),
provides for indemnification of the Corporation's directors and officers to
the maximum extent permitted by Washington law.
 
  Section 23B.08.320 of the WBCA authorizes a corporation to eliminate or
limit a director's personal liability to the corporation or its shareholders
for monetary damages for conduct as a director, except in certain
circumstances involving acts or omissions, intentional misconduct by a
director or knowing violations of law by a director or distributions illegal
under Washington law, or any transaction from which the director will
personally receive a benefit in money, property or services to which the
director is not legally entitled. Article X of the Corporation's Restated
Articles of Incorporation, as amended (the "Articles of Incorporation")
contains provisions implementing, to the fullest extent permitted by
Washington law, such limitations on a director's liability to the Corporation
and its shareholders.
 
  Officers and directors of the Corporation are covered by insurance (with
certain exceptions and certain limitations) that indemnifies them against
losses and liabilities arising from certain alleged "wrongful acts," including
alleged errors or misstatements, or certain other alleged wrongful acts or
omissions constituting neglect or breach of duty.
 
  The above discussion of the WBCA and the Bylaws and Articles of
Incorporation is not intended to be exhaustive and is qualified in its
entirety by reference to such statute, the Bylaws and the Articles of
Incorporation.

ITEM 22. UNDERTAKINGS
 
  A. Each of the undersigned registrants hereby undertakes:
 
    (1) To file, during any period in which offers 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, unless the information required to be included
    in a post-effective amendment by this provision is contained in
    periodic reports filed with or furnished to the Commission by the
    registrant pursuant to Section 13 or Section 15(d) of the Securities
    Exchange Act of 1934 that are incorporated by reference in the
    registration statement.
 
      (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, unless the information required to be
    included in a post-effective amendment by this provision is contained
    in periodic reports filed with or furnished to the Commission by the
    registrant pursuant to Section 13 or Section 15(d) of the Securities
    Exchange Act of 1934 that are incorporated by reference in the
    registration statement.
 
                                     II-2
<PAGE>
 
      (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.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effect 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 unissued at the
  termination of the offering.
 
  B. Each of the undersigned registrants hereby undertakes that, for purposes
of determining any liability under the Securities Act of 1933, as amended,
each filing of a registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to 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.
 
  C. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
each undersigned registrant pursuant to the foregoing provisions, or
otherwise, each registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by each undersigned registrant of expenses incurred or paid by a
director, officer or controlling person of each 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, each registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.
 
  D. The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  E. The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired or involved therein, that was not the subject of and
included in the registration statement when it became effective.

duplication 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 semi-annually.  The amount of interest payable on any Interest
Payment Date shall be computed on the basis of a 360-day year of twelve 30-day
months and, for any period less than a full calendar month, the number of days
elapsed in such month.  In the event that any date on which the principal of (or
premium, if any) or interest on this Security is payable is not a Business Day,
then the payment 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), with the same force and effect as if made on such date. 
Pursuant to the Registration Rights Agreement, in certain limited circumstances 
the Company will be required to pay Liquidated Damages (as defined in the 
Registration Rights Agreement) with respect to this Security.

     The interest installment so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the person in whose name this Security (or one or more Predecessor Securities,
as defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, which shall be the May 15 or
November 15 immediately preceding the relevant interest payment date.  Any such
interest installment not punctually paid or duly provided for shall forthwith
cease to be payable to the holders on such regular record date and may be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) 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 shall be given to the holders of Securities not less than 10

                                      -3-
<PAGE>
 
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 Securities 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 premium, if any) and interest on this Security shall
be payable at the office or agency of the Trustee maintained for that purpose in
any coin or currency of the United States of America that 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 (i) check
mailed to the holder at such address as shall appear in the Security Register or
(ii) by transfer to an account maintained by the Person entitled thereto,
provided that proper written transfer instructions have been received by the
relevant record date.  Notwithstanding the foregoing, so long as the Holder of
this Security is the Property Trustee, the payment of the principal of (and
premium, if any) and interest on this Security will be made at such place and to
such account as may be designated by the Property Trustee.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and junior in right of payment to the prior payment
in full of all Senior Indebtedness, and this Security is issued subject to the
provisions of the Indenture with respect thereto.  Each holder of this Security,
by accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his or her 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 or her attorney-in-fact for any and
all such purposes.  Each holder hereof, by his or her 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
said provisions.

     This Security shall not be entitled to any benefit under the Indenture
hereinafter referred to, or be valid or become obligatory for any purpose until
the Certificate of Authentication hereon shall have been signed by or on behalf
of the Trustee.

     The provisions of this Security are continued on the reverse side hereof
and such provisions shall for all purposes have the same effect as though fully
set forth at this place.

                         (FORM OF REVERSE OF SECURITY)


     This Security is one of the Securities of the Company (herein sometimes
referred to as the "Securities"), specified in the Indenture, all issued or to
be issued under and pursuant to an Indenture, dated as of June 6, 1997 (the
"Indenture"), duly executed and delivered between the Company and The First
National Bank of Chicago, as Trustee (the "Trustee"), to which Indenture
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 Securities.

     Upon the occurrence and continuation of a Tax Event, the Company shall have
the right at any time, within 90 days following the occurrence of a Tax Event,
prior to June 1, 2007 (the "Initial Optional Redemption Date"), to redeem this
Security in whole (but not in part) at the Tax Event Redemption Price.  "Tax
Event Redemption Price" shall mean, with respect to any redemption of the
Securities following a Tax Event, an amount in cash equal to the greater of (i)
100% of the principal amount to be redeemed or (ii) the sum, as determined by a
Quotation Agent, of the present values of the remaining scheduled payments of
principal and interest on the Securities to Maturity Date, discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case, any
accrued and unpaid interest thereon, including Compounded Interest and
Additional Interest, if any, to the date of such redemption.

     In addition, the Company shall have the right to redeem this Security, in
whole or in part, at any time on or after the Initial Optional Redemption Date
(an "Optional Redemption"), at a redemption price (the "Optional Redemption
Price") equal to the percentage of the outstanding principal amount of the
Debentures specified below, plus, in each case, accrued interest thereon to the
date of redemption if redeemed during the 12-month period beginning June 1 of
the years indicated below.

     The Optional Redemption Price or the Tax Event Redemption Price, as the
case requires, shall be paid prior to 12:00 noon, New York time, on the date of
such redemption or at such earlier time as the Company determines, provided,
that the Company shall deposit with the Trustee an amount sufficient to pay the
applicable Redemption Price by 10:00 a.m., New York City time, on the date such
Redemption Price is to be paid.  Any redemption pursuant to this paragraph will
be made upon not less than 30 days nor more than 60 days notice.  If the
Securities are only partially redeemed by the Company pursuant to an Optional
Redemption, the Securities will be redeemed pro rata or by lot or by any other
method utilized by the Trustee; provided that if, at the time of redemption, the
Securities are registered as a Global Security, the Depositary shall determine
in accordance with its procedures the principal amount of such Securities held
for the account of its participants to be redeemed.

     In the event of redemption of this Security in part only, a new Security or
Securities for the unredeemed portion hereof will be issued in the name of the
holder hereof upon the cancellation hereof.

     Notwithstanding the foregoing, any redemption of Securities by the Company
shall be subject to the receipt by the Company of any required regulatory
approval.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Securities 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 permitting the Company and the Trustee,
with the consent of the holders of a majority in aggregate principal amount of
the Securities at the time outstanding, as defined in the Indenture, 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
modifying in any manner the rights of the holders of the Securities; provided,
however, that no such supplemental indenture shall, without the consent of each
holder of Securities then outstanding and affected thereby, (i) extend the
Maturity Date of any Securities, or reduce the principal amount thereof, or
reduce any amount payable on redemption thereof, or reduce the rate or extend
the time of payment of interest thereon (subject to Article XVI of the
Indenture), or make the principal of, premium, if any, or interest on, the
Securities payable in any coin or currency other than U.S. dollars, or impair or
affect the right of any holder of Securities to institute suit for the payment
thereof, or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to

                                      -9-
<PAGE>
 
consent to any such supplemental indenture.  The Indenture also contains
provisions permitting the holders of a majority in aggregate principal amount of
the Securities at the time outstanding, on behalf of all of the holders of the
Securities, to waive any past default in the performance of any of the covenants
contained in the Indenture, or established pursuant to the Indenture, and its
consequences, except a default in the payment of the principal of or premium, if
any, or interest on any of the Securities or a default in respect of any
covenant or provision under which the Indenture cannot be modified or amended
without the consent of each holder of Securities then outstanding.  Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such Holder and upon all
future holders and owners of this Security and of any Security 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 Security.

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

     The Company shall have the right, at any time and from time to time during
the term of the Securities, to defer payments of interest by extending the
interest payment period of such Securities for a period not exceeding 10
consecutive semi-annual periods, including the first such semi-annual period
during such extension period, and not to extend beyond the Maturity Date of the
Securities (an "Extended Interest Payment Period"), at the end of which period
the Company shall pay all interest then accrued and unpaid (together with
interest thereon at the rate specified for the Securities to the extent that
payment of such interest is enforceable under applicable law).  Before the
termination of any such Extended Interest Payment Period, the Company may
further defer payments of interest by further extending such Extended Interest
Payment Period, provided that such Extended Interest Payment Period, together
with all such previous and further extensions within such Extended Interest
Payment Period, shall not exceed 10 consecutive semi-annual periods, including
the first semi-annual period during such Extended Interest Payment Period shall
not end on any date other than an Interest Payment Date, or extend beyond the
Maturity Date of the Securities. Upon the termination of any such Extended
Interest Payment Period and the payment of all accrued and unpaid interest and
any additional amounts then due, the Company may commence a new Extended
Interest Payment Period, subject to the foregoing requirements.

                                      -10-

     The Company has agreed that it will not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock (which includes common and
preferred stock) or (ii) make any payment of principal, interest or premium, if
any, on or repay or repurchase or redeem any debt securities of the Company that
rank pari passu with or junior in right of payment to the Securities or (iii)
make any guarantee payments with respect to any guarantee by the Company of any
securities or any Subsidiary of the Company (including any Other Guarantees) if
such guarantee ranks pari passu or junior in right of payment to the Securities
(other than (a) dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, Common Stock of the Company; (b)
any declaration of a dividend in connection with the implementation of a
stockholder's rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto; (c)
payments under the Capital Securities Guarantee; (d) as a direct result of, and
only to the extent required in order to avoid the issuance of fractional shares
of capital stock, following a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock; and (e) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
exchange or conversion of such capital stock or the security being exchanged or
converted) if at such time (i) an Event of Default shall have occurred and be
continuing, (ii) there shall have occurred any event of which the Company has
actual knowledge that (a) is, or with the giving of notice or the lapse of time,
or both, would be, an Event of Default and (b) in respect of which the Company
shall not have taken reasonable steps to cure, (iii) the Company shall be in
default with respect to its payment obligations under the Capital Securities
Guarantee or (iv) the Company shall have given notice of its election of the
exercise of its right to extend the interest payment period, or any extension
thereof, pursuant to Section 16.01 of the Indenture and shall not have rescinded
such notice, and such exercise of its right to extend the interest payment
period, or any extension thereof, shall have commenced.

     The Securities are issuable only in registered form without coupons in
denominations of $1,000.00 and any integral multiple thereof. As provided in the
Indenture and subject to the transfer restrictions limitations as may be
contained herein and therein from time to time, this Security is transferable by
the holder hereof on the Security Register of the Company, upon surrender of
this Security for registration of transfer at the office or agency of the
Company in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company or the Security
registrar duly executed by the holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securities of authorized denominations
and for the same aggregate principal amount

                                      -11-
<PAGE>
 
and series 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 Security, the
Company, the Trustee, any authenticating agent, any paying agent, any transfer
agent and the registrar may deem and treat the holder hereof as the absolute
owner hereof (whether or not this Security shall be overdue and notwithstanding
any notice of ownership or writing hereon made by anyone other than the Security
registrar) for the purpose of receiving payment of or on account of the
principal hereof and premium, if any, and (subject to the Indenture) interest
due hereon and for all other purposes, and neither the Company nor the Trustee
nor any authenticating agent nor any paying agent nor any transfer agent nor any
registrar shall be affected by any notice to the contrary.

     No recourse shall be had for the payment of the principal of or premium, if
any, or interest on this Security, or for any claim based hereon, or otherwise
in respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor Person, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

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

     THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PROVISIONS THEREOF.

                              THE FIRST NATIONAL BANK OF CHICAGO,
                              as Property Trustee

                              By:
                              Authorized Signatory

                         [FORM OF REVERSE OF SECURITY]

     Distributions payable on each Capital Security will be fixed at a rate per
annum of 8.231% (the "Coupon Rate") of the liquidation amount of $1,000 per
Capital Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee.  Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law).  Pursuant to the 
Registration Rights Agreement, in certain limited circumstances the Debenture 
Issurer will be required to pay Liquidated Damages (as defined in the 
Registration Rights Agreement) with respect to the Debentures.  The term
"Distributions", as used herein, includes such cash distributions and any such
interest payable unless otherwise stated.  A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has funds on hand legally
available therefor.

     Distributions on the Capital Securities will be cumulative, will accumulate
from the most recent date to which Distributions have been paid or, if any
Distributions have been paid, from December 1, 1997 and will be payable semi-
annually in arrears, on June 1 and December 1 of each year, commencing on June
1, 1998, except as otherwise described below.  Distributions will be computed on
the basis of a 360-day year consisting of twelve 30-day months and, for any
period less than a full calendar month, the number of days elapsed in such
month.  As long as no Event of Default has occurred and is continuing under the
Indenture, the Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period at any time and
from time to time on the Debentures for a period not exceeding 10 consecutive
calendar semi-annual periods, including the first such semi-annual period during
such extension period (each an "Extension Period"); provided that no Extension
                                                    -------- ----             
Period shall extend beyond the Maturity Date of the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite such
deferral, semi-annual Distributions will continue to accumulate with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate
compounded semi-annually during any such Extension Period.  Prior to the
termination of any such Extension Period, the Debenture Issuer may further defer
payments of interest by further extending such Extension Period; provided that
                                                                 -------- ----
such Extension Period, together with all such previous and further extensions
within such Extension Period, may not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during such Extension Period, or extend
beyond the Maturity Date of the Debentures.  Payments of accumulated
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the first record date after the end of the Extension Period.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Extension Period, subject to the
above requirements.

     Subject to the prior obtaining of any regulatory approval then required and
to certain other conditions set forth in the Declaration and the Indenture, the
Property Trustee may, at the direction of the Sponsor, at any time liquidate the
Trust and cause the Debentures to be distributed to the holders of the
Securities in liquidation of the Trust or, simultaneous with any redemption of
the Debentures, cause a Like Amount of the Securities to be redeemed by the
Trust.

     The Capital Securities shall be redeemable as provided in the Declaration.

delivered by Puget Sound Energy, Inc., a Washington corporation (the
"Guarantor"), and The First National Bank of Chicago, a national banking
association, as trustee (the "Capital Securities Guarantee Trustee"), for the
benefit of the Holders (as defined herein) from time to time of the Series B
Capital Securities (as defined herein) of Puget Sound Energy Capital Trust I, a
Delaware statutory business trust (the "Issuer").

     WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of June 6, 1997, among the trustees of the Issuer, the
Guarantor, as sponsor, and the holders from time to time of undivided beneficial
interests in the assets of the Issuer, the Issuer issued on June 6, 1997 100,000
capital securities, having an aggregate liquidation amount of $100,000,000, such
capital securities being designated the 8.231% Series A Capital Securities
(collectively the "Series A Capital Securities"), executed and delivered a
guarantee agreement dated as of June 6, 1997 (the "Series A Capital Securities
Guarantee") and, in connection with the Exchange Offer (as defined in the
Declaration), is issuing on the date hereof this Series B Capital Securities
Guarantee for the benefit of holders of the Series B Capital Securities (as 
defined in the Declaration).

     WHEREAS, as incentive for the holders of the Series A Capital Securities to
exchange such securities for the Series B Capital Securities, the Guarantor
desires irrevocably and unconditionally to agree, to the extent set forth in
this Series B Capital Securities Guarantee, to pay to the Holders (as defined

     WHEREAS, the Guarantor has executed and delivered a guarantee agreement
(the "Common Securities Guarantee"), with substantially identical terms to this
Series B Capital Securities Guarantee, for the benefit of the holders of the
Common Securities (as defined herein), except that if an Event of Default (as
defined in the Declaration) has occurred and is continuing, the rights of
holders of the Common Securities to receive Guarantee Payments under the Common
Securities Guarantee are subordinated, to the extent and in the manner set forth
in the Common Securities Guarantee, to the rights of holders of Series A Capital
Securities and the Series B Capital Securities to receive Guarantee Payments
under the Series A Capital Securities Guarantee and this Series B Capital
Securities Guarantee, as the case may be.

     NOW, THEREFORE, in consideration of the exchange by each holder of Series A
Capital Securities for Series B Capital Securities, which exchange the Guarantor
hereby acknowledges shall benefit the Guarantor, the Guarantor executes and
delivers this Series B Capital Securities Guarantee for the benefit of the
Holders.

conferred on the Holders pursuant to the terms of the Series B Capital

extension of any kind;

          (d) the voluntary or involuntary liquidation, dissolution, sale of any

Issuer;

or hereby incurred;

          (g) the consummation of the Exchange Offer; or

          (h) any other circumstance whatsoever that might otherwise constitute

conducting any proceeding for any remedy available to the Capital Securities
Guarantee Trustee in respect of this Series B Capital Securities Guarantee or
exercising any trust or power conferred upon the Capital Securities Guarantee
Trustee under this Series B Capital Securities Guarantee; provided, however,

Indenture, the Capital Securities Guarantee Trustee shall have the right to
decline to follow any such direction if the Capital Securities Guarantee Trustee
shall determine that the action so directed would be unjustly prejudicial to the
Holders not taking part in such direction or if the Capital Securities Guarantee
Trustee being advised by counsel determines that the action or proceeding so
directed may not lawfully be taken or if the Capital Securities Guarantee
Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or Responsible
Officers shall determine that the action or proceedings so directed would
involve the Capital Securities Guarantee Trustee in personal liability.

          (b) If the Capital Securities Guarantee Trustee fails to enforce such
Series B Capital Securities Guarantee, any Holder may institute a legal
proceeding directly against the Guarantor to enforce the Capital Securities
Guarantee Trustee's rights under this Series B Capital Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Capital

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.

provisions of law) be entitled to enforce or exercise any right that it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Series B Capital
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Series B Capital Securities Guarantee.  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.

Securities, and that the Guarantor shall be liable as principal and as debtor

Capital Securities Guarantee notwithstanding the occurrence of any event
referred to in subsections (a) through (h), inclusive, of Section 5.3 hereof.

trustees and other representatives of the Company, the Trust and others.

     Members of this Firm are admitted to the Bar of the State of Delaware, and
we express no opinion as to the laws of any other jurisdiction.

     Based upon and subject to the foregoing, we are of the opinion that:

     1. The Capital Securities have been duly authorized for issuance by the
Trust, and when (i) the Registration Statement becomes effective and the
Declaration has been qualified under the Trust Indenture Act of 1939, as
amended, and (ii) the Capital Securities are duly executed, authenticated and
issued in accordance with the Declaration and delivered and issued in the
Exchange Offer as contemplated by the Registration Rights Agreement and the
Registration Statement, the Capital Securities will represent, subject to the
qualifications set forth in paragraph 2 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

     2. The holders of the Capital Securities 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 bring to your attention, however, that the holders of the
Capital Securities may be obligated, pursuant to the Declaration, to (i) provide
indemnity and/or security in connection with, and pay taxes or governmental
charges arising from, transfers of Capital Securities and the issuance of
replacement Capital Securities and (ii) provide security and indemnity in
connection with requests of or directions to the Property

     This opinion is being furnished in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Act.

     In connection with this opinion, we have examined originals, or copies
certified or otherwise identified to our satisfaction, of (i) the Registration
Statement; (ii) an executed copy of the Registration Rights Agreement, dated as
of June 6, 1997 (the "Registration Rights Agreement"), among the Company, Smith
Barney Inc., Goldman, Sachs & Co. and Salomon Brothers Inc; (iii) the Indenture;
(iv) the Amended and Restated Declaration of Trust, dated as of June 6, 1997
(the "Declaration") among James P. Torgerson, Donald E. Gaines and Tommy G.
Leong, as Administrative Trustees, First National Bank of Chicago, as Property
Trustee, First Chicago Delaware Inc., as Delaware Trustee and the Company, as
Sponsor; (v) the form of the Junior Subordinated Debentures and a specimen
certificate thereof; (vi) the Guarantee Agreement and (vii) the Restated
Articles of Incorporation, as amended, and Bylaws of the Company.  We have also
examined originals or copies, certified or otherwise identified to our
satisfaction, of such other documents, certificates and records as we have
deemed necessary or appropriate as a basis for the opinions set forth herein.

     In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such latter documents.  In making our
examination of documents executed by parties other than the Company, we have
assumed that such parties had the power, corporate or other, to enter into and
perform all obligations thereunder and have also assumed the due authorization
by all requisite action, corporate or other, and execution and delivery by such
parties of such documents and the validity and binding effect thereof on such
parties.  As to any facts material to the opinions expressed herein which we did
not independently establish or verify, we have relied upon oral or written
statements and representations of officers, trustees and other representatives
of the Company, the Trust and others.

     We are qualified to practice law in the state of Washington and do not
express any opinion as to any laws other than the federal laws of the United 
States and the internal laws of the state of Washington ordinarily applicable to
the transactions contemplated by the Guarantee Agreement, the Declaration, the 
Indenture and the Registration Rights Agreement.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.  The Guarantee Agreement has been duly authorized by the Company, and
when (i) the Registration Statement becomes effective and the Declaration and
Indenture have been qualified under the Trust Indenture Act of 1939, as amended
(the "TIA"), and (ii) the Guarantee Agreement is duly executed and delivered by
the Company and issued in the Exchange Offer as contemplated by the Registration
Rights Agreement and the Registration Statement, the Guarantee Agreement will
constitute a valid and binding agreement of the Company in favor of the holders
of Capital Securities, enforceable against the Company in accordance with its
terms, except to the extent that enforcement thereof may be limited by (i)
bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors' rights
generally and (ii) general principles of equity (regardless of whether
enforceability is considered in a proceeding at law or in equity).

     2.  The Junior Subordinated Debentures have been duly authorized for
issuance and sale by the Company and when (i) the Registration Statement becomes
effective and the Declaration and Indenture have been qualified under the TIA
and (ii) the Junior Subordinated Debentures are duly executed, authenticated and
issued in accordance with the Indenture and delivered and issued in the Exchange
Offer as contemplated by the Registration Rights Agreement and the Registration
Statement, the Junior Subordinated Debentures will constitute valid and binding
obligations of the Company enforceable against the Company in accordance with
their terms, except to the extent that enforcement thereof may be limited by (i)
bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors' rights
generally and (ii) general principles of equity (regardless of whether
enforceability is considered in a proceeding at law or in equity).

firm under the caption "Validity of Exchange Securities" in the Registration

     Re:  8.231% Capital Securities (the "Capital Securities") of Puget Sound 
          Energy Capital Trust I

Ladies and Gentlemen:

     We have acted as counsel to Puget Sound Energy, Inc., a Washington 
corporation (the "Corporation"), and Puget Sound Energy Capital Trust I, a 
Delaware business trust (the "Trust"), in connection with an offer of exchange 
by the Trust of $100,000,000 aggregate Liquidation Amount of its Series B 
Capital Securities, which are issued and outstanding, in a registration 
statement on Form S-4 (Registration No. 333-      ) filed with the Securities 
and Exchange Commission on October 24, 1997 and the Prospectus contained therein
(together with amendments thereto, the "Registration Statement"), for a like 
Liquidation Amount of its outstanding 8.231% Series A Capital Securities. 
Capitalized terms used herein without definition have the respective meanings 
specified in the Registration Statement.

     In connection with this opinion, we have examined the Registration 
Statement and such other documents as we have deemed necessary. Furthermore, we 
have relied upon certain statements and representations made by officers of the 
Corporation and others. We have also examined originals or copies, certified or 
otherwise identified to our satisfaction, of such other documents, certificates 
and records as we have deemed necessary or appropriate as a basis for the 
opinion set forth herein.

     In rendering our opinion, we have participated in the preparation of the 
Registration Statement. Our opinion is conditioned on, among other things, the 
initial and continuing accuracy of the facts, information, covenants and 
representations set forth in the documents referred to above and the statements 
and representations made by officers of the Corporation and others. In our 
examination, we have assumed the

<PAGE>

Page 2

genuineness of all signatures, the legal capacity of natural persons, the 
authenticity of all documents submitted to us as originals, the conformity to 
original documents of all documents submitted to us as certified or photostatic 
copies and that the transactions related to the exchange of the Capital 
Securities will be consummated in the manner contemplated by the Registration 
Statement.

     In rendering our opinion, we have considered the provisions of the Internal
Revenue Code of 1986, as amended, Treasury Regulations promulgated thereunder, 
judicial decisions, and Internal Revenue Service rulings, all as in effect on
the date hereof and all of which are subject to change, which changes may be
retroactively applied. A change in the authorities upon which our opinion is
based could affect our conclusions.

     Based upon and subject to the foregoing, and subject to the discussion and 
limitations set forth in the Registration Statement under the heading "CERTAIN 
FEDERAL INCOME TAX CONSEQUENCES," we are of the opinion that, although the 
discussion set forth in the Registration Statement under the heading "CERTAIN 
FEDERAL INCOME TAX CONSEQUENCES" does not purport to discuss all possible United
States federal income tax consequences of the purchase, ownership and 
disposition of Capital Securities, such discussion constitutes a fair and 
accurate summary of the material United States federal income tax considerations
(other than considerations that are material to a Non-U.S. Holder based on such 
Non-U.S. Holder's particular tax situation) for holders of the Capital 
Securities under current law.

     Except as set forth above, we express no opinion to any party as to the tax
consequences, whether federal, state, local or foreign, of the issuance, 
exchange or sale of the Capital Securities or any transactions related to or 
contemplated by such issuance, exchange or sale. We hereby consent to the filing
of this opinion as an exhibit to the Registration Statement and any amendment 
thereto. In giving such consent, we do not thereby admit that we are in the 
category of persons whose consent is required under Section 7 of the Securities 
Act of 1933, as amended.

     We disclaim any undertaking to advise you of any subsequent changes of the 
facts assumed herein or any subsequent changes in applicable law.

                                        Very truly yours,

                         FORMING PART OF THE TERMS AND

                        CONDITIONS OF THE EXCHANGE OFFER

     1.   DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED
          DELIVERY PROCEDURES.

     This Letter of Transmittal is to be completed either if (a) Certificates
are to be forwarded herewith or (b) tenders are to be made pursuant to the
procedures for tender by book-entry transfer set forth under "The Exchange
Offer--Procedures for Tendering Original Capital Securities" in the Prospectus
and an Agent's Message is not delivered.  Certificates, or book-entry
confirmation of a book-entry transfer of such Original Capital Securities into
the Exchange Agent's account at DTC, as well as this Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or an Agent's Message in lieu thereof, and any other
documents required by this Letter of Transmittal, must be received by the
Exchange Agent at its address set forth herein on or prior to the Expiration
Date.  Original Capital Securities may be tendered in whole or in part in the
liquidation amount of $100,000 (100 Capital Securities) and integral multiples
of $1,000 in excess thereof, provided that, if any Original Capital Securities
are tendered for exchange in part, the untendered liquidation amount thereof
must be $100,000 (100 Capital Securities) or any integral multiple of $1,000 in
excess thereof.

     Holders who wish to tender their Original Capital Securities and (i) whose
Original Capital Securities are not immediately available or (ii) who cannot
deliver their Original Capital Securities, this Letter of Transmittal and all
other required documents to the Exchange Agent on or prior to the Expiration
Date or (iii) who cannot complete the procedures for delivery by book-entry
transfer on or prior to the Expiration Date, may tender their Original Capital
Securities by properly completing and duly executing a Notice of Guaranteed
Delivery pursuant to the guaranteed delivery procedures set forth under "The
Exchange Offer--Procedures for Tendering Original Capital Securities" in the
Prospectus.  Pursuant to such procedures:  (i) such tender must be made by or
through an Eligible Institution (as defined below); (ii) a properly completed
and duly executed Notice of Guaranteed Delivery, substantially in the form made
available by the Company and the Trust, must be received by the Exchange Agent
on or prior to the Expiration Date; and (iii) the Certificates (or a book-entry
confirmation (as defined in the Prospectus)) representing all tendered Original
Capital Securities, in proper form for transfer, together with a Letter of
Transmittal (or facsimile thereof or Agent's Message in lieu thereof), properly
completed and duly executed, with any required signature guarantees and any
other documents required by this Letter of Transmittal, must be received by the
Exchange Agent within three New York Stock Exchange trading days after the date
of execution of such Notice of Guaranteed Delivery, all as provided in "The
Exchange Offer--Procedures for Tendering Original Capital Securities" in the
Prospectus.

     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such Notice.  For Original Capital
Securities to be properly 

                                      -14-
<PAGE>
 
tendered pursuant to the guaranteed delivery procedure, the Exchange Agent must
receive a Notice of Guaranteed Delivery on or prior to the Expiration Date. As
used herein and in the Prospectus, "Eligible Institution" means a firm or other
entity identified in Rule 17Ad-15 under the Exchange Act as "an eligible
guarantor institution," including (as such terms are defined therein) (i) a
bank; (ii) a broker, dealer, municipal securities broker or dealer or government
securities broker or dealer; (iii) a credit union; (iv) a national securities
exchange, registered securities association or clearing agency; or (v) a savings
association that is a participant in a Securities Transfer Association
recognized program.

     THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS, IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT.  IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN RECEIPT
REQUESTED, PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY ON OR
PRIOR TO THE EXPIRATION DATE.  NO DOCUMENTS SHOULD BE SENT TO THE COMPANY OR THE
TRUST.  DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE
EXCHANGE AGENT.

     Neither the Company nor the Trust will accept any alternative, conditional
or contingent tenders.  Each tendering holder, by execution of a Letter of
Transmittal (or facsimile thereof or Agent's Message in lieu thereof), waives
any right to receive any notice of the acceptance of such tender.

     2.   GUARANTEE OF SIGNATURES.

     No signature guarantee on this Letter of Transmittal is required if:

            (i) this Letter of Transmittal is signed by the registered holder
     (which term, for purposes of this document, shall include any participant
     in DTC whose name appears on a security position listing as the owner of
     the Original Capital Securities) of Original Capital Securities tendered
     herewith, unless such holder has completed either the box entitled "Special
     Issuance Instructions" or the box entitled "Special Delivery Instructions"
     above, or

            (ii) such Original Capital Securities are tendered for the account
     of a firm that is an Eligible Institution.

     In all other cases, an Eligible Institution must guarantee the signature on
this Letter of Transmittal.  See Instruction 5.

                                      -15-
<PAGE>
 
     3.   INADEQUATE SPACE.

     If the space provided in the box captioned "Description of Original Capital
Securities" is inadequate, the Certificate numbers and/or the liquidation amount
of Original Capital Securities and any other required information should be
listed on a separate signed schedule which is attached to this Letter of
Transmittal.

     4.   PARTIAL TENDERS AND WITHDRAWAL RIGHTS.

     Tenders of Original Capital Securities will be accepted only in the
liquidation amount of $100,000 (100 Capital Securities) and integral multiples
of $1,000 in excess thereof, provided that if any Original Capital Securities
are tendered for exchange in part, the untendered liquidation amount thereof
must be $100,000 (100 Capital Securities) or any integral multiple of $1,000 in
excess thereof.  If less than all of the Original Capital Securities evidenced
by any Certificate submitted are to be tendered, fill in the liquidation amount
of Original Capital Securities which are to be tendered in the box entitled
"Liquidation Amount of Original Capital Securities Tendered (If Less than All)."
In such case, a new Certificate for the remainder of the Original Capital
Securities that were evidenced by your Old Certificate will be sent to the
holder of the Original Capital Securities, promptly after the Expiration Date
unless the appropriate boxes on this Letter of Transmittal are completed.  All
Original Capital Securities represented by Certificates delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.

     Except as otherwise provided herein, tenders of Original Capital Securities
may be withdrawn at any time on or prior to the Expiration Date.  In order for a
withdrawal to be effective on or prior to that time, a written or facsimile
transmission of such notice of withdrawal must be timely received by the
Exchange Agent at its address set forth above or in the Prospectus on or prior
to the Expiration Date.  Any such notice of withdrawal must specify the name of
the person who tendered the Original Capital Securities to be withdrawn, the
aggregate liquidation amount of Original Capital Securities to be withdrawn, and
(if Certificates for Original Capital Securities have been tendered) the name of
the registered holder of the Original Capital Securities as set forth on the
Certificate for the Original Capital Securities, if different from that of the
person who tendered such Original Capital Securities.  If Certificates for the
Original Capital Securities have been delivered or otherwise identified to the
Exchange Agent, then prior to the physical release of such Certificates for the
Original Capital Securities, the tendering holder must submit the serial numbers
shown on the particular Certificates for the Original Capital Securities to be
withdrawn and the signature on the notice of withdrawal must be guaranteed by an
Eligible Institution, except in the case of Original Capital Securities tendered
for the account of an Eligible Institution.  If Original Capital Securities have
been tendered pursuant to the procedures for book-entry transfer set forth under
"The Exchange Offer--Procedures for Tendering Original Capital Securities," the
notice of withdrawal must specify the name and number of the account at DTC to
be credited with the withdrawal of Original Capital Securities, in which case a
notice of withdrawal will be effective if delivered to the Exchange Agent by
written or facsimile transmission on or prior to the Expiration Date.
Withdrawals of tenders of Original Capital Securities may not be

                                      -16-
<PAGE>
 
rescinded.  Original Capital Securities properly withdrawn will not be deemed
validly tendered for purposes of the Exchange Offer, but may be retendered at
any subsequent time on or prior to the Expiration Date by following any of the
procedures described in the Prospectus under "The Exchange Offer--Procedures for
Tendering Original Capital Securities."

     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company and the
Trust, in their sole discretion, whose determination shall be final and binding
on all parties.  Neither the Company, the Trust, any affiliates or assigns of
the Company or the Trust, the Exchange Agent nor any other person shall be under
any duty to give any notification of any irregularities in any notice of
withdrawal or incur any liability for failure to give any such notification.
Any Original Capital Securities which have been tendered but which are withdrawn
on or prior to the Expiration Date will be returned to the holder thereof
without cost to such holder promptly after withdrawal.

     5.   SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Original Capital Securities tendered hereby, the signature(s) must correspond
exactly with the name(s) as written on the face of the Certificate(s) or on a
security position listing without alteration, enlargement or any change
whatsoever.

     If any of the Original Capital Securities tendered hereby are owned of
record by two or more joint owners, all such owners must sign this Letter of
Transmittal.

     If any tendered Original Capital Securities are registered in different
names on several Certificates, it will be necessary to complete, sign and submit
as many separate Letters of Transmittal (or facsimiles thereof or Agent's
Messages in lieu thereof) as there are different registrations of Certificates.

     If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and must submit proper evidence
satisfactory to the Company and the Trust, in their sole discretion, of such
persons' authority to so act.

     When this Letter of Transmittal is signed by the registered owner of the
Original Capital Securities listed and transmitted hereby, no endorsement of
Certificates or separate bond powers are required unless Exchange Capital
Securities are to be issued in the name of a person other than the registered
holder.  Signatures on such Certificates or bond powers must be guaranteed by an
Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered owner of the Original Capital Securities listed, the Certificates
must be endorsed or accompanied by appropriate bond powers, signed exactly as
the name of the registered owner appears on the

                                      -17-
<PAGE>
 
Certificates, and also must be accompanied by such opinions of
counsel, certifications and other information as the Company, the Trust or the
Exchange Agent may require in accordance with the restrictions on transfer
applicable to the Original Capital Securities.  Signatures on such Certificates
or bond powers must be guaranteed by an Eligible Institution.

     6.   SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.

     If Exchange Capital Securities are to be issued in the name of a person
other than the signer of this Letter of Transmittal, or if Exchange Capital
Securities are to be sent to someone other than the signer of this Letter of
Transmittal or to an address other than that shown above, the appropriate boxes
on this Letter of Transmittal should be completed.  Certificates for Original
Capital Securities not exchanged will be returned by mail or, if tendered by
book-entry transfer, by crediting the account indicated above maintained at DTC
unless the appropriate boxes on this Letter of Transmittal are completed.  See
Instruction 4.

     7.   IRREGULARITIES.

     The Company and the Trust will determine, in their sole discretion, all
questions as to the form of documents, validity, eligibility (including time of
receipt) and acceptance for exchange of any tender of Original Capital
Securities, which determination shall be final and binding on all parties.  The
Company and the Trust reserve the absolute right to reject any and all tenders
determined by either of them not to be in proper form or the acceptance of
which, or exchange for, may, in the view of counsel to the Company or the Trust,
be unlawful.  The Company and the Trust also reserve the absolute right, subject
to applicable law, to waive any of the conditions of the Exchange Offer set
forth in the Prospectus under "The Exchange Offer--Conditions to Exchange
Offer," or any conditions or irregularities in any tender of Original Capital
Securities of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders.  The Company and the
Trust's interpretation of the terms and conditions of the Exchange Offer
(including this Letter of Transmittal and the instructions hereto) will be final
and binding.  No tender of Original Capital Securities will be deemed to have
been validly made until all irregularities with respect to such tender have been
cured or waived.  The Company, the Trust, any affiliates or assigns of the
Company, the Trust, the Exchange Agent, or any other person shall not be under a
duty to give notification of any irregularities in tenders or incur any
liability for failure to give such notification.

     8.   QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES.

at its address and telephone number set forth on the front of this Letter of
Transmittal.  Additional copies of the Prospectus, the Notice of Guaranteed

     9.   LOST, DESTROYED OR STOLEN CERTIFICATES.

     If any Certificates representing Original Capital Securities have been
lost, destroyed or stolen, the holder should promptly notify the Exchange Agent.
The holder will then be instructed as to the steps that must be taken in order
to replace the Certificates.  This Letter of Transmittal and related documents
cannot be processed until the procedures for replacing lost, destroyed or stolen
Certificates have been followed.

     10.  SECURITY TRANSFER TAXES.

     Holders who tender their Original Capital Securities for exchange will not
be obligated to pay any transfer taxes in connection therewith.  If, however,
Exchange Capital Securities are to be delivered to, or are to be issued in the
name of, any person other than the registered holder of the Original Capital
Securities tendered, or if a transfer tax is imposed for any reason other than
the exchange of Original Capital Securities in connection with the Exchange
Offer, then the amount of any such transfer tax (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.

     11.  INCORPORATION OF LETTER OF TRANSMITTAL.

     This Letter of Transmittal shall be deemed to be incorporated in and

     The Company and the Trust reserve the absolute right to waive satisfaction
of any or all conditions enumerated in the Prospectus.

     13.  NO CONDITIONAL TENDERS.

tendering holders of Original Capital Securities, by execution of this Letter of
Transmittal, shall waive any right to receive notice of the acceptance of
Original Capital Securities for exchange.

obligated to give notice of any defect or irregularity with respect to any
tender of Original Capital Securities nor shall any of them incur any liability
for failure to give any such notice.

                           IMPORTANT TAX INFORMATION

     Under federal income tax law, a holder whose tendered Original Capital
Securities are accepted for exchange is required by law to provide the Exchange
Agent with such holder's correct taxpayer identification number ("TIN") on
Substitute Form W-9 included herein or otherwise establish a basis for exemption
from backup withholding.  If such holder is an individual, the TIN is his social
security number.  If the Exchange Agent is not provided with the correct TIN,
the Internal Revenue Service may subject the holder or transferee to a $50
penalty.  In addition, delivery of such holder's Exchange Capital Securities may
be subject to backup withholding.  Failure to comply truthfully with the backup
withholding requirements also may result in the imposition of severe criminal
and/or civil fines and penalties.

     Certain holders (including, among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements.  Exempt holders should furnish their TIN, write "Exempt" on the
face of the Substitute Form W-9, and sign, date and return the Substitute Form
W-9 to the Exchange Agent.  A foreign person, including entities, may qualify as
an exempt recipient by submitting to the Exchange Agent a properly completed
Internal Revenue Service Form W-8, signed under penalties of perjury, attesting
to that holder's foreign status.  See the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
instructions.

     If backup withholding applies, the Exchange Agent is required to withhold
31% of any payments made to the holder or other transferee.  Backup withholding
is not an additional federal income tax.  Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld.  If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

     To prevent backup withholding on payments made with respect to Original
Capital Securities exchanged in the Exchange Offer, the holder is required to
provide the Exchange Agent with either:  (i) the holder's correct TIN by
completing the form included herein, certifying that the TIN provided on
Substitute Form W-9 is correct (or that such holder is awaiting a TIN) and that
(A) the holder has not been notified by the Internal Revenue Service that the
holder is subject to backup withholding as a result of failure to report all
interest or dividends or (B) the Internal Revenue Service has notified the
holder that the holder is no longer subject to backup withholding; or (ii) an
adequate basis for exemption.

     The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future.  If the box in Part 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Exchange Agent.  The Exchange Agent will retain such amounts
withheld during the 60-day

                                      -20-
<PAGE>
 
period following the date of the Substitute Form W-9.  If the holder furnishes
the Exchange Agent with its TIN within 60 days after the date of the Substitute
Form W-9, the amounts retained during the 60-day period will be remitted to the
holder and no further amounts shall be retained or withheld from payments made
to the holder thereafter.  If, however, the holder has not provided the Exchange
Agent with its TIN within such 60-day period, amounts withheld will be remitted
to the IRS as backup withholding.  In addition, 31% of all payments made
thereafter will be withheld and remitted to the IRS until a correct TIN is
provided.

NUMBER TO GIVE THE DEPOSITARY

     The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered holder of
the Original Capital Securities or of the last transferee appearing on the
transfers attached to, or endorsed on, the Original Capital Securities.  If the
Original Capital Securities are held in more than one name or are held not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which number to report.

             CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

     I certify under penalties of perjury that a taxpayer identification number
has not been issued to me, and either (a) I have mailed or delivered an
application to receive a taxpayer identification number to the appropriate
Internal Revenue Service Center or Social Security Administration Office or (b)

Ladies and Gentlemen:

     Puget Sound Energy Capital Trust I, a trust formed under the laws of the
State of Delaware (the "Trust") proposes to make an offer (the "Exchange Offer")
to exchange its 8.231% Series A Capital Securities (Liquidation Amount $1,000
per Capital Security) (the "Original Capital Securities") for its 8.231% Series
B Capital Securities (Liquidation Amount $1,000 per Capital Security) (the
"Exchange Capital Securities").  All of the beneficial interests represented by
common securities of the Trust are owned by Puget Sound Energy, Inc., a
Washington corporation (the "Corporation").  The terms and conditions of the
Exchange Offer as currently contemplated are set forth in a prospectus, dated
__________, 1997 (the "Prospectus"), to be distributed to all record holders of
the Original Capital Securities.  The Original Capital Securities and the
Exchange Capital Securities are collectively referred to herein as the
"Securities."

     The Trust hereby appoints The First National Bank of Chicago to act as
exchange agent (the "Exchange Agent") in connection with the Exchange Offer.
References hereinafter to "you" shall refer to The First National Bank of
Chicago.

     The Exchange Offer is expected to be commenced by the Trust on or about

of the Original Capital Securities to accept the Exchange Offer and contains
instructions with respect to (i) the delivery of certificates for Original
Capital Securities tendered in connection therewith and (ii) the book-entry
transfer of Securities to the Exchange Agent's account.

     The Exchange Offer shall expire at 5:00 P.M., New York City time, on

Exchange Offer (the "Expiration Date").  Subject to the terms and conditions set
forth in the Prospectus, the Trust expressly reserves the right to extend the
Exchange Offer from time to time by giving oral (to be confirmed in writing) or
written notice to you before 9:00 A.M., New York City time, on the business day
following the previously scheduled Expiration Date.

<PAGE>
 
     The Trust expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Original Capital Securities not

of the Exchange Offer specified in the Prospects under the caption "The Exchange
Offer--Conditions to the Exchange Offer."  The Trust will give oral (confirmed
in writing) or written notice of any amendment, termination or nonacceptance of
Original Capital Securities to you promptly after any amendment, termination or
nonacceptance.

     In carrying out your duties as Exchange Agent, you are to act in accordance
with the following instructions:

     1.  You will perform such duties and only such duties as are specifically
set forth in the section of the Prospectus captioned "The Exchange Offer" or as
specifically set forth herein; provided, however, that in no way will your
general duty to act in good faith be discharged by the foregoing.

     2.  You will establish an account with respect to the Original Capital
Securities at The Depository Trust Company (the "Book-Entry Transfer Facility")
for purposes of the Exchange Offer within two business days after the date of
the Prospectus, and any financial institution that is a participant in the Book-
Entry Transfer Facility's system may make book-entry delivery of the Original
Capital Securities by causing the Book-Entry Transfer Facility to transfer such
Original Capital Securities into your account in accordance with the Book-Entry
Transfer Facility's procedure for such transfer.

     3.  You are to examine each of the Letters of Transmittal and certificates
for Original Capital Securities (or confirmation of book-entry transfer into
your account at the Book-Entry Transfer Facility) and any other documents
delivered or mailed to you by or for holders of the Original Capital Securities
to ascertain whether: (a) the Letters of Transmittal and any such other
documents are duly executed and properly completed in accordance with
instructions set forth therein and (b) the Original Capital Securities have
otherwise been properly tendered.  In each case where the Letter of Transmittal
or any other document has been improperly completed or executed or any of the
certificates for Original Capital Securities are not in proper form for transfer
or some other irregularity in connection with the acceptance of the Exchange
Offer exists, you will endeavor to inform the presenters of the need for
fulfillment of all requirements and to take any other action as may be necessary
or advisable to cause such irregularity to be corrected.

     4.  With the approval of any Administrative Trustee of the Trust or any
person designated in writing by the Corporation (a "Designated Officer") (such
approval, if given orally, to be confirmed in writing) or any other party
designated by any such Administrative Trustee or Designated Officer in writing,
you are authorized to waive any irregularities in connection with any tender of
Original Capital Securities pursuant to the Exchange Offer.

                                       2

     5.  Tenders of Original Capital Securities may be made only as set forth in
the Letter of Transmittal and in the section of the Prospectus captioned "The
Exchange Offer--Procedures for Tendering Original Capital Securities," and
Original Capital Securities shall be considered properly tendered to you only
when tendered in accordance with the procedures set forth therein.

     Notwithstanding the provisions of this paragraph 5, Original Capital
Securities which any Administrative Trustee of the Trust or Designated Officer
of the Corporation shall approve as having been properly tendered shall be
considered to be properly tendered (such approval, if given orally, shall be
confirmed in writing).

     6.  You shall advise the Trust and the Corporation with respect to any
Original Capital Securities received subsequent to the Expiration Date and
accept their instructions with respect to disposition of such Original Capital
Securities.

     7.  You shall accept tenders:

         (a)  in cases where the Original Capital Securities are registered in
two or more names only if signed by all named holders;

         (b)  in cases where the signing person (as indicated on the Letter of
Transmittal) is acting in a fiduciary or a representative capacity only when
proper evidence of such person's authority so to act is submitted; and

         (c)  from persons other than the registered holder of Original Capital
Securities provided that customary transfer requirements, including any
applicable transfer taxes, are fulfilled.

     You shall accept partial tenders of Original Capital Securities where so
indicated and as permitted in the Letter of Transmittal and deliver certificates
for Original Capital Securities to the transfer agent for split-up and return
any untendered Original Capital Securities to the holder (or such other person
as may be designated in the Letter of Transmittal) as promptly as practicable
after expiration or termination of the Exchange Offer.

     8.  Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Trust will notify you (such notice, if given orally, to be confirmed
in writing) of its acceptance, promptly after the Expiration Date, of all
Original Capital Securities properly tendered and you, on behalf of the Trust,
will exchange such Original Capital Securities for Exchange Capital Securities
and cause such Original Capital Securities to be canceled.  Delivery of Exchange
Capital Securities will be made on behalf of the Trust by you at the rate of
$1,000 principal amount of Exchange Capital Securities for each $1,000 principal
amount of the corresponding series of Original Capital Securities tendered
promptly after notice (such notice if given orally, to be confirmed in writing)
of 

                                       3
<PAGE>
 
acceptance of said Original Capital Securities by the Trust; provided, however,
that in all cases, Original Capital Securities tendered pursuant to the Exchange
Offer will be exchanged only after timely receipt by you of certificates for
such Original Capital Securities (or confirmation of book-entry transfer into
your account at the Book-Entry Transfer Facility), a properly completed and duly
executed Letter of Transmittal (or facsimile thereof) with any required
signature guarantees and any other required documents. You shall issue Exchange
Capital Securities only in denominations of $1,000 or any integral multiple
thereof. Original Capital Securities may be tendered in whole or in part in
denominations of $100,000 and integral multiples of $1,000 in excess thereof,
provided that if any Original Capital Securities are tendered for exchange in
part, the untendered principal amount thereof must be $100,000 or any integral
multiple of $1,000 in excess thereof.

     9.  Tenders pursuant to the Exchange Offer are irrevocable, except that,
subject to the terms and upon the conditions set forth in the Prospectus and the
Letter of Transmittal, Original Capital Securities tendered pursuant to the
Exchange Offer may be withdrawn at any time on or prior to the Expiration Date.

     10.  The Trust shall not be required to exchange any Original Capital
Securities tendered if any of the conditions set forth in the Exchange Offer are
not met.  Notice of any decision by the Trust not to exchange any Original
Capital Securities tendered shall be given orally (and confirmed in writing) or
in writing by the Trust to you.

     11.  If, pursuant to the Exchange Offer, the Trust does not accept for
exchange all or part of the Original Capital Securities tendered because of an
invalid tender, the occurrence of certain other events set forth in the
Prospectus under the caption "The Exchange Offer--Conditions to the Exchange
Offer" or otherwise, you shall promptly after the expiration or termination of
the Exchange Offer return those certificates for unaccepted Original Capital
Securities (or effect appropriate book-entry transfer), together with any
related required documents and the Letters of Transmittal relating thereto that
are in your possession, to the persons who deposited them.

     12.  All certificates for reissued Original Capital Securities, unaccepted
Original Capital Securities or for Exchange Capital Securities shall be
forwarded by (a) first-class certified mail, return receipt requested, under a
blanket surety bond protecting you and the Trust from loss or liability arising
out of the nonreceipt or nondelivery of such certificates, (b) by registered
mail insured separately for the replacement value of each of such certificates,
or (c) by appropriate book-entry transfer.

     13.  You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons or
to engage or utilize any person to solicit tenders.

     14.  As Exchange Agent hereunder, you

                                       4
<PAGE>
 
         (a)  shall have no duties or obligations other than those specifically
set forth in the section of the Prospectus captioned "The Exchange Offer," the
Letter of Transmittal or herein or as may be subsequently agreed to in writing
by you and the Trust;

         (b)  will be regarded as making no representations and having no
responsibilities as to the validity, sufficiency, value or genuineness of any of
the certificates or the Original Capital Securities represented thereby
deposited with you pursuant to the Exchange Offer, and will not be required to
and will make no representation as to the validity, value or genuineness of the
Exchange Offer;

         (c)  shall not be obligated to take any legal action hereunder which
might in your reasonable judgment involve any expense or liability, unless you
shall have been furnished with reasonable indemnity;

         (d)  may reasonably rely on and shall be protected in acting in
reliance upon any certificate, instrument, opinion, notice, letter, telegram or
other document or security delivered to you and reasonably believed by you to be
genuine and to have been signed by the proper party or parties;

         (e)  may reasonably act upon any tender, statement, request, agreement
or other instrument whatsoever not only as to its due execution and the validity
and effectiveness of its provisions, but also as to the truth and accuracy of
any information contained therein, which you shall in good faith believe to be
genuine or to have been signed or represented by a proper person or persons;

         (f)  may rely on and shall be protected in acting upon written or oral
instructions from any Administrative Trustee of the Trust or from any Designated
Officer of the Corporation;

         (g)  may consult with your counsel with respect to any questions
relating to your duties and responsibilities and the advice or opinion of such
counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted to be taken by you hereunder in good faith
and in accordance with the advice or opinion of such counsel; and

         (h)  shall not advise any person tendering Original Capital Securities
pursuant to the Exchange Offer as to the wisdom of making such tender or as to
the market value or decline or appreciation in market value of any Original
Capital Securities.

     15.  You shall take such action as may from tine to time be requested by
the Trust or its counsel or any Designated Officer of the Corporation (and such
other action as you may reasonably deem appropriate) to furnish copies of the
Prospectus, Letter of Transmittal and the Notice of Guaranteed Delivery (as
defined in the Prospects) or such 

                                       5
<PAGE>
 
other forms as may be approved from time to time by the Trust or the
Corporation, to all persons requesting such documents and to accept and comply
with telephone requests for information relating to the Exchange Offer, provided
that such information shall relate only to the procedures for accepting (or
withdrawing from) the Exchange Offer. The Trust will furnish you with copies of
such documents at your request. All other requests for information relating to
the Exchange Offer shall be directed to the Trust, Attention: Donald E. Gaines.

     16.  You shall advise by facsimile transmission or telephone, and promptly
thereafter confirm in writing to Donald E. Gaines of the Trust, and such other
person or persons as the Trust or the Corporation may request, daily (and more
frequently during the week immediately preceding the Expiration Date and if
otherwise requested) up to and including the Expiration Date, as to the number
of Original Capital Securities which have been tendered pursuant to the Exchange
Offer and the items received by you pursuant to this Agreement, separately
reporting and giving cumulative totals as to items properly received and items
improperly received.  In addition, you will also inform, and cooperate in making
available to, the Trust or the Corporation or any such other person or persons
upon oral request made from time to time on or prior to the Expiration Date of
such other information as it or such person reasonably requests.  Such
cooperation shall include, without limitation, the granting by you to the Trust
or the Corporation and such person as the Trust or the Corporation may request
of access to those persons on your staff who are responsible for receiving
tenders, in order to ensure that immediately prior to the Expiration Date the
Trust or the Corporation shall have received information in sufficient detail to
enable it to decide whether to extend the Exchange Offer.  You shall prepare a
final list of all persons whose tenders were accepted, the aggregate principal
amount of Original Capital Securities tendered, the aggregate principal amount
of Original Capital Securities accepted and deliver said list to the Trust
promptly after the Expiration Date.

     17.  Any Letters of Transmittal and Notices of Guaranteed Delivery which
are received by the Exchange Agent shall be stamped by you as to the date and
the time of receipt thereof and shall be preserved by you for a period of time
at least equal to the period of time you preserve other records pertaining to
the transfer of securities.  You shall dispose of unused Letters of Transmittal
and other surplus materials by returning them to the Trust at the address set
forth below for notices.

     18.  You hereby expressly waive any lien, encumbrance or right of set-off
whatsoever that you may have with respect to funds deposited with you for the
payment of transfer taxes by reasons of amounts, if any, borrowed by the Trust,
or any of its subsidiaries or affiliates pursuant to any loan or credit
agreement with you or for compensation owed to you hereunder.

                                       6
<PAGE>
 
     19.  For services rendered as Exchange Agent hereunder, you shall be
entitled to such compensation as set forth on Schedule I attached hereto.

     20.  You hereby acknowledge receipt of the Prospectus and the Letter of
Transmittal and further acknowledge that you have examined each of them.  Any
inconsistency between this Agreement, on the one hand, and the Prospectus and
the Letter of Transmittal (as they may be amended from time to time), on the
other hand, shall be resolved in favor of the latter two documents, except with
respect to the duties, liabilities and indemnification of you as Exchange Agent,
which shall be controlled by this Agreement.


     21.  (a)  The Trust covenants and agrees to indemnify and hold you harmless
in your capacity as Exchange Agent hereunder against any loss, liability, cost
or expense, including reasonable attorneys' fees and expenses, arising out of or
in connection with any act, omission, delay or refusal made by you in reliance
upon any signature, endorsement, assignment, certificate, order, request,
notice, instruction or other instrument or document reasonably believed by you
to be valid, genuine and sufficient and in accepting any tender or effecting any
transfer of Original Capital Securities reasonably believed by you in good faith
to be authorized, and in delaying or refusing in good faith to accept any
tenders or effect any transfer of Original Capital Securities; provided,
however, that the Trust shall not be liable for indemnification or otherwise for
any loss, liability, cost or expense to the extent arising out of your gross
negligence or willful misconduct.  In no case shall the Trust be liable under
this indemnity with respect to any claim against you unless the Trust shall be
notified by you, by letter or cable or by facsimile confirmed by letter, of the
written assertion of a claim against you or of any other action commenced
against you, promptly after you shall have received any such written assertion
or notice of commencement of action.  The Trust shall be entitled to participate
at its own expense in the defense of any such claim or other action, and, if the
Trust so elects, the Trust may assume the defense of any suit brought to enforce
any such claim.  In the event that the Trust shall assume the defense of any
such suit or threatened action in respect of which indemnification may be sought
hereunder, the Trust shall not be liable for the fees and expenses of any
additional counsel thereafter retained by you so long as you consent to the
Trust's retention of counsel, which consent may not be unreasonably withheld;
provided that the Trust shall not be entitled to assume the defense of any such
action if the named parties to such action include both the Trust and you and
representation of both parties by the same legal counsel would, in the written
opinion of counsel to you, be inappropriate due to actual or potential
conflicting interests between you and the Trust.  It is understood that the
Trust shall not be liable under this paragraph for the fees and expenses of more
than one legal counsel for you.  In the event that the Trust shall assume the
defense of any such suit, the Trust shall not thereafter be liable for the fees
and expenses of any counsel retained by you.

                                       7
<PAGE>
 
          (b)  You agree that, without the prior written consent of the Trust
(which consent shall not be unreasonably withheld), you will not settle,
compromise or consent to the entry of any pending or threatened claim, action or
proceeding in respect of which indemnification could be sought in accordance
with the indemnification provisions of this Agreement (whether or not you or the
Trust or any of its trustees, or controlling persons is an actual or potential
party to such claim, action or proceeding), unless such settlement, compromise
or consent includes an unconditional release of the Trust and its trustees and
controlling persons from all liability arising out of such claim, action or
proceeding.

     22.  You shall arrange to comply with all requirements under the tax laws
of the United States, including those relating to missing Tax Identification
Numbers, and shall file any appropriate reports with the Internal Revenue
Service.  The Trust understands that you are required in certain instances to
deduct 31% with respect to interest paid on the Exchange Capital Securities and
proceeds from the sale, exchange, redemption or retirement of the Exchange
Capital Securities from holders who have not supplied their correct Taxpayer
Identification Number or required certification.  Such funds will be turned over
to the Internal Revenue Service in accordance with applicable regulations.

     23.  You shall notify the Trust of the amount of any transfer taxes payable
in respect of the exchange of Original Capital Securities and, upon receipt of
written approval from the Trust, you shall deliver or cause to be delivered, in
a timely manner, to each governmental authority to which any transfer taxes are
payable in respect of the exchange of Original Capital Securities, your check in
the amount of all transfer taxes so payable, and the Trust shall reimburse you
for the amount of any and all transfer taxes payable in respect of the exchange
of Original Capital Securities; provided, however, that you shall reimburse the
Trust for amounts refunded to you in respect of your payment of any such
transfer taxes, at such time as such refund is received by you.

     24.  This Agreement and your appointment as Exchange Agent hereunder shall
be construed and enforced in accordance with the laws of the State of New York
applicable to agreements made and to be performed entirely within such state,
and without regard to conflicts of law principles, and shall inure to the
benefit of, and the obligations created hereby shall be binding upon, the
successors and assigns of each of the parties hereto.

     25.  This Agreement may be executed in one or more counterparts, each of
which shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

     26.  In case any provision of 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.

amended, rescinded, canceled or waived, in whole or in part, except by a written
instrument signed by a duly authorized representative of the party to be

     28.  Unless otherwise provided herein, all notices, requests and other
communications to any party hereunder shall be in writing (including facsimile
