(2)  ComEd and the Trust have agreed to indemnify the several Underwriters
     against certain liabilities, including liabilities under the Securities Act
     of 1933, as amended.  See "Underwriting."
(3)  In view of the fact that the proceeds of the sale of the Preferred
     Securities will be invested in Subordinated Notes, ComEd has agreed to pay
     to the Underwriters as compensation for their arranging the investment
     therein of such proceeds, $________ per Preferred Security (or $________ in
     the aggregate); provided, that such compensation for sales of 10,000 or
     more Preferred Securities to a single purchaser will be ________ per
     Preferred Security.  Therefore, to the extent of such sales, the actual
     amount of Underwriters' compensation will be less than the aggregate amount
     specified in the preceding sentence.  See "Underwriting."
(4)  Expenses of the offering which are payable by ComEd are estimated to be
     $500,000.

     The Preferred Securities offered hereby are offered severally by the

be subordinate and junior in right of payment to certain other indebtedness of
ComEd, as described herein. Upon an event of default under the Declaration (as
defined herein), the holders of the Preferred Securities will have a preference
over the holders of the Common Securities with respect to payments in respect of
distributions and payments upon liquidation, redemption and otherwise.

          Holders of the Preferred Securities are entitled to receive cumulative
cash distributions at an annual rate of __ % of the liquidation amount of $25
per Preferred Security, accruing from the date of original issuance and payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year commencing September 30, 1995 ("distributions").  The payment of
distributions out of moneys held by the Trust, and payments on liquidation of
the Trust or the redemption of Preferred Securities, as set forth below, are
guaranteed by ComEd (the "Preferred Securities Guarantee") to the extent the
Trust has funds available therefor as described under "Description of the
Preferred Securities Guarantee."  The obligations of ComEd under the Preferred
Securities Guarantee are subordinate and junior in right of payment to all other
liabilities of ComEd and will rank pari passu with the most senior preferred
stock issued by ComEd.  The obligations of ComEd under the Subordinated Notes
are subordinate and junior in right of payment to all present and future Senior
Indebtedness (as defined herein) of ComEd.  The Senior Indebtedness of ComEd
aggregated approximately $8,231 million at June 30, 1995.

          The distribution rate and the distribution and other payment dates for
the Preferred Securities will correspond to the interest rate and interest and
other payment dates on the Subordinated Notes, which will be the sole assets of
the Trust. As a result, if principal or interest is not paid on the Subordinated
Notes, no amounts will be paid on the Preferred Securities.  If ComEd does not
make principal or interest payments on the Subordinated Notes, the Trust will
not have sufficient funds to make distributions on the Preferred Securities, in
which event the Preferred Securities Guarantee will not apply to such
distributions until the Trust has sufficient funds available therefor.

          ComEd has the right to defer payments of interest on the Subordinated
Notes by extending the interest payment period on the Subordinated Notes, at any
time, for up to 20 consecutive quarters (each, an "Extension Period").  If
interest payments are so deferred, distributions will also be deferred.  Despite
such deferral, distributions will continue to accrue with interest thereon (to
the extent permitted by applicable law) at an annual rate of __% per annum,
compounded quarterly, and during any Extension Period, holders of Preferred
Securities will be required to include deferred interest income in their gross
income for United States federal income tax purposes in advance of receipt of
the cash interest payments attributable to such deferred income.  There could be
multiple Extension Periods of varying lengths throughout the term of the
Subordinated Notes.  See "Description of the Subordinated Notes -- Option to
Extend Interest Payment Period," "Risk Factors -- Option to Extend Interest
Payment Period" and "Certain Federal Income Tax Consequences -- Original Issue
Discount, Premium and Market Discount."

          The Subordinated Notes are redeemable by ComEd (in whole or in part)
from time to time, on or after September 30, 2000 or at any time in certain
circumstances upon the occurrence of a Tax Event (as defined herein).  If ComEd
redeems Subordinated Notes, the Trust must redeem Trust Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Subordinated Notes so redeemed at $25 per Trust Security plus accrued and unpaid
distributions thereon (the "Redemption Price") to the date fixed for redemption.
See "Description of the Preferred Securities -- Mandatory Redemption." The
Preferred Securities will be redeemed upon maturity of the Subordinated Notes.
The Subordinated Notes mature on September 30, 2035.  In addition, upon the
occurrence of a Special Event (as defined herein) arising from a change in law
or a change in legal interpretation, unless the Subordinated Notes are redeemed
in the limited circumstances described below, the Trust shall be dissolved with
the result that the Subordinated Notes will be distributed to the holders of the
Preferred Securities, on a pro rata basis, in lieu of any cash distribution.  In
the case of the occurrence of a Special Event that is a Tax Event, ComEd will
have the right in certain circumstances to redeem the Subordinated Notes, which
would result in the redemption by the Trust of the Trust Securities in the same
amount on a pro rata basis.  If the Subordinated Notes are distributed to the
holders of the Preferred Securities, ComEd will use its best efforts to have the
Subordinated Notes listed on the New York Stock Exchange or on such other
exchange as the Preferred Securities are then listed.  See "Description of the
Preferred Securities -- Special Event Redemption or Distribution" and
"Description of the Subordinated Notes."

          In the event of the voluntary or involuntary dissolution, winding up
or termination of the Trust, the holders of the Preferred Securities will be
entitled to receive, for each Preferred Security, a liquidation amount of $25
plus accrued and unpaid distributions thereon (including interest thereon) to
the date of payment, unless in connection with such dissolution, the
Subordinated Notes are distributed to the holders of the Preferred Securities.
See "Description of the Preferred Securities --Liquidation Distribution Upon
Dissolution."

          IN CONNECTION WITH THIS OFFERING, THE UNDERWRITERS MAY OVER-ALLOT OR
EFFECT TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE
SECURITIES OFFERED HEREBY AT LEVELS ABOVE THOSE WHICH MIGHT OTHERWISE PREVAIL IN
THE OPEN MARKET.  SUCH TRANSACTIONS MAY BE EFFECTED ON THE NEW YORK STOCK
EXCHANGE, IN THE OVER-THE-COUNTER MARKET OR OTHERWISE.  SUCH STABILIZING, IF
COMMENCED, MAY BE DISCONTINUED AT ANY TIME.

          IT IS EXPECTED THAT DELIVERY OF THE PREFERRED SECURITIES WILL BE MADE
AGAINST PAYMENT THEREFOR ON OR ABOUT THE DATE SPECIFIED IN THE LAST PARAGRAPH OF
THE COVER PAGE, WHICH IS THE FIFTH BUSINESS DAY FOLLOWING THE DATE HEREOF (SUCH
SETTLEMENT CYCLE BEING HEREIN REFERRED TO AS "T+5").  PURCHASERS OF THE
PREFERRED SECURITIES SHOULD NOTE THAT THE ABILITY TO SETTLE SECONDARY MARKET

Commission (the "Commission") a combined registration statement on Form S-3

made to the exhibit for a more complete description of the matter involved.

          ComEd is subject to the informational requirements of the Securities

                               PROSPECTUS SUMMARY


          The following summary is qualified in its entirety by reference to the
detailed information appearing elsewhere in this Prospectus.  Reference is made
to "Definitions" herein for the location herein of the definitions of certain
capitalized terms used herein.

          Preferred Securities Offered.  8,000,000 ___% Trust Originated
Preferred Securities evidencing preferred undivided beneficial interests in the
assets of the Trust are offered hereby.  Holders of the Preferred Securities are
entitled to receive cumulative cash distributions at an annual rate of ___% of
the liquidation amount of $25 per Preferred Security, accruing from the date of
original issuance and payable quarterly in arrears on March 31, June 30,
September 30 and December 31 of each year commencing on September 30, 1995.  The
distribution rate and the distribution and other payment dates for the Preferred
Securities will correspond to the interest rate and interest and other payment
dates on the Subordinated Notes, which will be the sole assets of the Trust.  As
a result, if principal or interest is not paid on the Subordinated Notes, no
amounts will be paid on the Preferred Securities.  See "Description of the
Preferred Securities."

          Subordinated Notes.  The Trust will invest the proceeds from the
issuance of the Preferred Securities and Common Securities in an equivalent
amount of ___% Subordinated Deferrable Interest Notes due 2035 of ComEd.  The
Subordinated Notes will be subordinate and junior in right of payment to all
Senior Indebtedness of ComEd.  See "Description of Subordinated Notes--
Subordination."

          Preferred Securities Guarantee.  Payment of distributions out of
moneys held by the Trust, and payments on liquidation of the Trust or the
redemption of Preferred Securities are guaranteed by ComEd to the extent the
Trust has funds available therefor.  If ComEd does not make principal or
interest payments on the Subordinated Notes, the Trust will not have sufficient
funds to make distributions on the Preferred Securities, in which event the
Preferred Securities Guarantee will not apply to such distributions until the
Trust has sufficient funds available therefor.  See "Description of Preferred
Securities Guarantee" and "Effect of Obligations under the Subordinated Notes
and the Preferred Securities Guarantee" herein.  The obligations of ComEd under
the Preferred Securities Guarantee are subordinate and junior in right of
payment to all other liabilities of ComEd and will rank pari passu with the most
senior preferred stock issued by ComEd.  See "Risk Factors--Ranking of

Preferred Securities Guarantee and Subordinated Notes" and "Description of the
Preferred Securities Guarantee."

          Interest Deferral.  ComEd has the right to defer payments of interest
on the Subordinated Notes by extending the interest payment period on the
Subordinated Notes, at any time, for up to 20 consecutive quarters.  If interest
payments on the Subordinated Notes are so deferred, distributions on the
Preferred Securities will also be deferred.  During any deferral, distributions
will continue to accrue with interest thereon (to the extent permitted by law)
as described herein.  There could be multiple Extension Periods of varying
lengths throughout the term of the Subordinated Notes.  During an Extension
Period, holders of Preferred Securities will be required to include deferred
interest income in their gross income in advance of receipt of the cash interest
payments attributable thereto.  See "Description of the Subordinated Notes--
Option to Extend Interest Payment Period" and "Certain Federal Income Tax
Consequences--Original Issue Discount, Premium and Market Discount."

          Redemption.  The Subordinated Notes are redeemable by ComEd (in whole
or in part) from time to time, on or after September 30, 2000, or at any time in
certain circumstances upon the occurrence of a Tax Event.  If the Subordinated
Notes are redeemed, the Trust must redeem Trust Securities having an aggregate
liquidation amount equal to the aggregate principal amount of Subordinated Notes
so redeemed.  The Preferred Securities will be redeemed upon maturity of the
Subordinated Notes.  See "Description of the Preferred Securities--Mandatory
Redemption."


                                  RISK FACTORS

          Prospective purchasers of Preferred Securities should carefully review
the information contained or incorporated by reference elsewhere in this
Prospectus and should particularly consider the following matters:

RANKING OF PREFERRED SECURITIES GUARANTEE AND SUBORDINATED NOTES

          ComEd's obligations under the Preferred Securities Guarantee are
subordinate and junior in right of payment to all liabilities of ComEd and pari
passu with the most senior preferred stock now or hereafter issued by ComEd and
with any guarantee now or hereafter entered into by ComEd in respect of any
preferred stock of any affiliate of ComEd. The obligations of ComEd under the
Subordinated Notes are subordinate and junior in right of payment to all present
and future Senior Indebtedness (as defined herein) of ComEd.  At June 30, 1995,
Senior Indebtedness of ComEd aggregated approximately $8,231 million.  There are
no terms in the Preferred Securities, the Subordinated Notes or the Preferred
Securities Guarantee that limit ComEd's ability to incur additional
indebtedness, including indebtedness that ranks senior to the Subordinated Notes
or the Preferred Securities Guarantee.  See "Description of the Preferred
Securities Guarantee" and "Description of the Subordinated Notes--
Subordination."

RIGHTS UNDER THE PREFERRED SECURITIES GUARANTEE

          The Preferred Securities Guarantee guarantees to the holders of the
Preferred Securities the payment of (i) any accrued and unpaid distributions
which are required to be paid on the Preferred Securities, to the extent the
Trust shall have funds available therefor, (ii) the Redemption Price, including
all accrued and unpaid distributions, to the date of the redemption, to the
extent the Trust has funds available therefor, with respect to any Preferred
Securities called for redemption by the Trust and (iii) upon a voluntary or
involuntary dissolution, winding-up or termination of the Trust (other than in
connection with the distribution of Subordinated Notes to the holders of
Preferred Securities the lesser of (a) the aggregate of the liquidation amount
and all accrued and unpaid distributions on the Preferred Securities to the date
of payment therefor and (b) the amount of assets of the Trust

                                      -5-
<PAGE>
 
remaining available for distribution to holders of Preferred Securities in
liquidation of the Trust.  The holders of a majority in liquidation amount of
the Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Preferred Guarantee
Trustee (as defined herein) or to direct the exercise of any trust or power
conferred upon the Preferred Guarantee Trustee under the Preferred Securities
Guarantee.  If the Preferred Guarantee Trustee fails to enforce the Preferred
Securities Guarantee, any holder of Preferred Securities may institute a legal
proceeding directly against ComEd to enforce the Preferred Guarantee Trustee's
rights under the Preferred Securities Guarantee, without first instituting a
legal proceeding against the Trust, the Preferred Guarantee Trustee or any other
person or entity.  If ComEd were to default in its obligation to pay amounts
payable on the Subordinated Notes, the Trust would lack available funds for the
payment of distributions or amounts payable on redemption of the Preferred
Securities or otherwise, and in such event holders of the Preferred Securities
would not be able to rely upon the Preferred Securities Guarantee for payment of
such amounts.  Instead, holders of the Preferred Securities would rely on the
enforcement by the Property Trustee (as defined herein) of its rights as
registered holder of the Subordinated Notes against ComEd, pursuant to the terms
of the Subordinated Notes.  See "Description of the Preferred Securities
Guarantee -- Status of the Preferred Securities Guarantee" and "Description of
the Subordinated Notes -- Subordination."  The Declaration (as defined herein)
provides that each holder of Preferred Securities by acceptance thereof agrees
to the provisions of the Preferred Securities Guarantee and the Indenture (as
defined herein).

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES

          If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Property Trustee of its rights as a holder of the
Subordinated Notes against ComEd.  In addition, the holders of a majority in
aggregate liquidation amount of the Preferred Securities will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Property Trustee or to direct the exercise of any trust or
power conferred upon the Property Trustee under the Declaration, including the
right to direct the Property Trustee to exercise the remedies available to it as
a holder of the Subordinated Notes.  If the Property Trustee fails to enforce
its rights under the Subordinated Notes, a holder of Preferred Securities may,
after a period of 30 days has elapsed from such holder's written request to the
Property Trustee to enforce such rights, institute a legal proceeding directly
against ComEd to enforce the Property Trustee's rights under the Subordinated
Notes without first instituting any legal proceeding against the Property
Trustee or any other person or entity, including the Trust.

OPTION TO EXTEND INTEREST PAYMENT PERIOD

          ComEd has the right under the Indenture to defer payments of interest
on the Subordinated Notes by extending the interest payment period at any time,
and from time to time, on the Subordinated Notes.  As a consequence of such an
extension, quarterly distributions on the Preferred Securities would be deferred
(but despite such deferral would continue to accrue with interest thereon
compounded quarterly) by the Trust during any such extended interest payment
period.  Such right to extend the interest payment period for the Subordinated
Notes is limited to a period not exceeding 20 consecutive quarters for any such
extension.  In the event that ComEd exercises this right to defer payments of
interest, then (a) ComEd shall not declare or pay any dividend on, make any
distributions with respect to, or redeem, purchase or make a liquidation payment
with respect to, any of its capital stock, (b) ComEd shall not make any payment
of interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees) issued by ComEd which rank pari passu
with or junior to the Subordinated Notes and (c) ComEd shall not make any
guarantee payments with respect to the foregoing (other than pursuant to the
Preferred Securities Guarantee).  Prior to the termination of any such Extension
Period, ComEd may further defer payments of interest by further extending the
interest payment period, provided that such Extension Period, together with all
such previous and further extensions thereof, may not exceed 20 consecutive
quarters or extend

                                      -6-
<PAGE>
 
beyond the maturity of the Subordinated Notes.  Upon the termination of any
Extension Period and the payment of all amounts then due, ComEd may select a new
Extension Period, as if no Extension Period had previously been declared,
subject to the above requirements.  See "Description of the Preferred Securities
- -- Distributions" and "Description of the Subordinated Notes -- Option to Extend
Interest Payment Period."

          Should ComEd exercise its rights to defer payments of interest by
extending the interest payment period, each holder of Preferred Securities will
continue to accrue income (as original issue discount) for United States federal
income tax purposes in respect of the deferred interest allocable to its
Preferred Securities.  As a result, holders of Preferred Securities will
recognize income for United States federal income tax purposes in advance of the
receipt of cash and will not receive cash from the Trust related to such income
if such holder disposes of its Preferred Securities prior to the record date for
the date on which distributions of such amounts are made.  ComEd has no current
intention of exercising its right to defer payments of interest by extending the
interest payment period on the Subordinated Notes.  However, should ComEd
determine to exercise such right in the future, the market price of the
Preferred Securities is likely to be affected.  A holder that disposes of its
Preferred Securities during an Extension Period, therefore, might not receive
the same return on its investment as a holder that continues to hold its
Preferred Securities.  In addition, as a result of the existence of ComEd's
right to defer interest payments, the market price of the Preferred Securities
(which represent an undivided beneficial interest in the Subordinated Notes) may
be more volatile than other securities on which original issue discount accrues
that do not have such rights.  See "Certain Federal Income Tax Consequences --
Original Issue Discount, Premium and Market Discount."

SPECIAL EVENT DISTRIBUTION

          Upon the occurrence of a Special Event, the Trust will be dissolved,
except in the limited circumstances described below, with the result that the
Subordinated Notes would be distributed to the holders of the Trust Securities
in connection with the liquidation of the Trust.  In the case of a Special Event
that is a Tax Event, in certain circumstances ComEd shall have the right to
redeem the Subordinated Notes, in whole or in part, in which event the Trust
will redeem the Trust Securities on a pro rata basis to the same extent as the
Subordinated Notes are redeemed.  See "Description of the Preferred Securities -
- - Special Event Redemption or Distribution" and "Certain Federal Income Tax
Consequences."

          There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Notes that may be distributed in exchange for
Preferred Securities if a dissolution or liquidation of the Trust were to occur.
Accordingly, the Preferred Securities that an investor may purchase, or the
Subordinated Notes that the investor may receive on dissolution and liquidation
of the Trust, may trade at a discount to the price that the investor paid to
purchase the Preferred Securities offered hereby.  Because holders of Preferred
Securities may receive Subordinated Notes upon the occurrence of a Special
Event, prospective purchasers of Preferred Securities are also making an
investment decision with regard to the Subordinated Notes and should carefully
review all the information regarding the Subordinated Notes and ComEd contained
herein.  See "Description of the Preferred Securities -- Special Event
Redemption or Distribution" and "Description of the Subordinated Notes."

LIMITED VOTING RIGHTS

          Holders of Preferred Securities will have limited voting rights and
will not be entitled to vote to appoint, remove or replace, or to increase or
decrease the number of, ComEd Trustees (as defined herein), which voting rights
are vested exclusively in ComEd as the holder of the Common Securities.

                                      -7-
<PAGE>
 
TRADING PRICE OF PREFERRED SECURITIES

          The Preferred Securities may trade at a price that does not fully
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Notes.  A holder who disposes of his Preferred Securities between
record dates for payments of distributions thereon will be required to include
accrued but unpaid interest on the Subordinated Notes through the date of
disposition in income as ordinary income (i.e., OID (as defined herein)), and to
add such amount to his adjusted tax basis in his pro rata share of the
underlying Subordinated Notes deemed disposed of.  To the extent the selling
price is less than the holder's adjusted tax basis (which will include, in the
form of OID, 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.  See
"Certain Federal Income Tax Consequences -- Original Issue Discount, Premium and
Market Discount" and "-- Sale of Preferred Securities."

                               COMED FINANCING I

          The Trust is a statutory business trust formed under Delaware law
pursuant to the filing of a certificate of trust with the Delaware Secretary of
State on July __, 1995.  The Trust's business is defined in a Declaration of
Trust, executed by ComEd, as sponsor (the "Sponsor"), and the ComEd Trustees (as
defined herein).  The Declaration of Trust will be amended and restated in its
entirety (as so amended and restated, the "Declaration") substantially in the
form filed as an exhibit to the Registration Statement of which this Prospectus
forms a part.  The Declaration will be qualified as an indenture under the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act").  Upon issuance of
the Preferred Securities, the purchasers thereof will own all of the Preferred
Securities.  ComEd will acquire all of the Common Securities in an aggregate
liquidation amount equal to 3% of the total capital of the Trust.  The Trust
exists for the exclusive purposes of (i) issuing the Trust Securities
representing undivided beneficial interests in the assets of the Trust, (ii)
investing the gross proceeds of the Trust Securities in the Subordinated Notes
and (iii) engaging in only those other activities necessary or incidental
thereto.  The Trust has a term of approximately 45 years, but may terminate
earlier as provided in the Declaration.

          The Trust's business and affairs will be conducted by the trustees
(the "ComEd Trustees") appointed by ComEd, as holder of the Common Securities.
The duties and obligations of the ComEd Trustees shall be governed by the
Declaration.  Pursuant to the Declaration, the number of ComEd Trustees will
initially be three.  Two of the ComEd Trustees (the "Regular Trustees") will be
persons who are employees or officers of, or affiliated with, ComEd.  The third
trustee will be a financial institution unaffiliated with ComEd which maintains
a principal place of business in the State of Delaware that will serve as
property trustee under the Declaration and as indenture trustee for purposes of
the Trust Indenture Act (the "Property Trustee").  Wilmington Trust Company will
act as

                                      -8-
<PAGE>
 
the Property Trustee until removed or replaced by the holder of the Common
Securities.  Wilmington Trust Company will also act as indenture trustee under
the Preferred Securities Guarantee (the "Preferred Guarantee Trustee").  See
"Description of the Preferred Securities Guarantee."

          The Property Trustee will hold title to the Subordinated Notes for the
benefit of the holders of the Trust Securities and will have the power to
exercise all rights, powers and privileges under the Indenture (as defined
herein) as the holder of the Subordinated Notes.  In addition, the Property
Trustee will maintain exclusive control of a segregated non-interest bearing
bank account (the "Property Account") to hold all payments made in respect of
the Subordinated Notes for the benefit of the holders of the Trust Securities.
The Property Trustee will make payments of distributions and payments on
liquidation, redemption and otherwise to the holders of the Trust Securities out
of funds from the Property Account.  The Preferred Guarantee Trustee will hold
the Preferred Securities Guarantee for the benefit of the holders of the
Preferred Securities.  ComEd, as the holder of all the Common Securities, will
have the right to appoint, remove or replace any ComEd Trustee and to increase
the number of ComEd Trustees, provided that the number of ComEd Trustees shall
be at least three, a majority of which shall be Regular Trustees.  ComEd will
pay all fees and expenses related to the Trust, the offering of the Trust
Securities and the issuance of the Subordinated Notes.  See "Description of the
Subordinated Notes -- Miscellaneous."

          The rights of the holders of the Preferred Securities, including
economic rights, rights to information and voting rights, are as set forth in
the Declaration, the Delaware Business Trust Act, as amended (the "Trust Act"),
and the Trust Indenture Act.  See "Description of the Preferred Securities."

          The Trustee in the State of Delaware is  Wilmington Trust Company,
Rodney Square North, 1100 North Market Street, Wilmington, Delaware  19890.  The
principal place of business of the Trust shall be c/o Commonwealth Edison
Company, 37th Floor, 10 South Dearborn Street, Chicago, Illinois 60690-0767
(telephone number 312/394-4321).

NOTES TO FINANCIAL INFORMATION:

(A)  In November 1993, two settlements related to various proceedings and
     matters concerning ComEd's rates and its fuel adjustment clause became
     final.  One settlement (the "Rate Matters Settlement") concerned the
     proceedings relating to ComEd's 1985 and 1991 ICC rate orders (which orders
     related to, among other things, the recovery of costs associated with
     ComEd's four most recently completed nuclear generating units, Byron Units
     1 and 2 and Braidwood Units 1 and 2), the proceedings concerning the
     reduction in the difference between ComEd's summer and non-summer
     residential rates that was effected in the summer of 1988, outstanding
     issues related to the appropriate interest rate and rate design to be
     applied to a refund made by ComEd during 1990 related to a 1988 ICC rate
     order, and matters related to a rider to ComEd's rates that it was required
     to file as a result of the change in the federal corporate income tax rate
     made by the Tax Reform Act of 1986.  The other settlement (the "Fuel
     Matters Settlement") related to the ICC fuel reconciliation proceedings
     involving ComEd for the period from 1985 through 1988 and to future
     challenges by the settling parties to the prudence of ComEd's western coal
     costs for the period from 1989 through 1992.

     Under the Rate Matters Settlement, effective as of November 4, 1993, ComEd
     reduced its rates by approximately $339 million annually and commenced
     refunding approximately $1.26 billion (including revenue taxes), plus
     interest at five percent on the unpaid balance, through temporarily reduced
     rates over an initial refund period which ended in November 1994 (followed
     by a reconciliation period of five months).  ComEd had previously deferred
     the recognition of revenues during 1993 as a result of developments in the
     proceedings related to the 1991 ICC rate order, which resulted in a
     reduction to 1993 net income of approximately $160 million or $0.75 per
     common share.  The recording of the effects of the Rate Matters Settlement
     in October 1993 reduced 1993 net income by approximately $292 million or
     $1.37 per common share, in addition to the approximately $160 million
     effect of the deferred recognition of revenues and after the partially
     offsetting effect of recording approximately $269 million or $1.26 per
     common share in deferred carrying charges, net of income taxes, authorized
     in the ICC rate order issued on January 6, 1993 (as subsequently modified,
     the "Remand Order").  The deferred recognition of revenues was eliminated
     in October 1993 at the time the provisions for revenue refunds related to
     the Rate Matters Settlement, which reflected those deferred revenues, were
     recorded.

     Under the Fuel Matters Settlement, effective as of December 2, 1993, ComEd
     commenced paying approximately $108 million (including revenue taxes) to
     its customers through temporarily reduced collections under its fuel
     adjustment clause over a twelve-month period which ended in November 1994.
     The recording of the effects of the Fuel Matters Settlement in October 1993
     reduced 1993 net income by approximately $62 million or $0.29 per common
     share.

(B)  During the periods presented under the subcaption "Financial Information"
     in "Selected Financial Information," ComEd's revenues, net income, cash
     flows, plant carrying costs, ratios of earnings to fixed charges and ratios
     of earnings to fixed charges and preferred and preference stock dividend
     requirements were affected directly by the proceedings that are the subject
     of the Rate Matters Settlement and the Fuel Matters Settlement. The
     uncertainties associated with such proceedings and related issues, among
     other things, led to the Rate Matters Settlement and the Fuel Matters
     Settlement.  See Note A for additional information.

     The Illinois Public Utilities Act requires the ICC to hold annual public
     hearings to determine whether each utility's fuel adjustment clause
     reflects actual costs of fuel and power prudently purchased and to
     reconcile amounts collected with actual costs.  Through its fuel adjustment
     clause, ComEd recovers from its customers the cost of the fuel used to
     generate electricity and of purchased power as compared to fuel costs
     included in base rates.

     ComEd is currently involved in proceedings relating to the amounts
     collected under its fuel adjustment clause with respect to 1993.  ICC
     orders have been issued in fuel reconciliation proceedings for years prior
     to 1993; however, certain intervenors have appealed the ICC order in the
     1989 fuel reconciliation proceedings on issues relating to nuclear station
     performance.  Under the Fuel Matters Settlement, parties to the settlement
     agreed not to challenge the prudence of ComEd's western coal costs for the
     period from 1989 through 1992.  ComEd's western coal contracts and its rail
     contracts for delivery of the western coal were renegotiated during 1992
     effective as of January 1, 1993, to provide, among other things, for
     significant reductions in the delivered price of the coal over the duration
     of the contracts.  However, the renegotiated contracts provide for the
     purchase of certain coal at prices substantially above currently prevailing
     market prices and ComEd has substantial purchase commitments under its
     contracts.  For additional information relating to ComEd's commitments for
     the purchase of coal, see "Management's Discussion and Analysis of
     Financial Condition and Results of Operations," subcaption "Liquidity and
     Capital Resources," and Notes 1 and 19 of Notes to Financial Statements in
     the March 31, 1995 Form 10-Q Report.

(C)  On January 9, 1995, the ICC issued its rate order (the "Rate Order") in the
     proceedings relating to ComEd's February 10, 1994 rate increase request.
     The Rate Order provides, among other things, for (i) an increase in ComEd's
     total revenues of approximately $301.8 million (excluding add-on revenue
     taxes) or 5.2%, on an annual basis, including a $303.2 million increase in
     base rates, (ii) the collection of municipal franchise costs as an adder to
     base rates until May 1, 1995, when ComEd began collecting such costs
     prospectively on an individual municipality basis through a rider, and
     (iii) the use of a rider, with annual review proceedings, to pass on to
     ratepayers increases or decreases in estimated costs associated with the
     decommissioning of ComEd's nuclear generating units.  The rates provided in
     the Rate Order became effective on January 14, 1995; however, they are
     being collected subject to refund as a result of subsequent judicial
     action.  Intervenors and ComEd have filed appeals of the Rate Order with
     the Illinois Appellate Court.  Electric operating revenues of approximately
     $139 million (excluding revenue taxes) are subject to refund.

     In the Rate Order, the ICC also determined that Byron Unit 2 and Braidwood
     Units 1 and 2 were 100% "used and useful" and that the previously
     determined reasonable costs of such Units, as depreciated, should be
     included in full in ComEd's rate base.  The ICC also determined, however,
     that ComEd's annual nuclear plant decommissioning cost collections from its
     ratepayers should be reduced from the $127 million previously authorized in
     the 1991 ICC rate order to $112.7 million.  The $112.7 million annual
     collection amount primarily resulted from the ICC's decision to exclude
     from ComEd's costs subject to collection a contingency allowance.  As noted
     above, the Rate Order established a rider which allows annual adjustments
     to decommissioning cost collections outside of the context of a traditional
     rate proceeding.  Such rider is intended to allow adjustments in
     decommissioning cost recoveries from ratepayers as changes in cost
     estimates become identifiable.  On April 19, 1995, the ICC approved ComEd's
     initial rider filing, which increased its annual collections to $113.5
     million.  Under Illinois law, decommissioning cost collections are required
     to be deposited in external trust funds; and, consequently, such
     collections do not add to the cash flows available for general corporate
     purposes.

(D)  For purposes of computing the ratios of earnings to fixed charges and the
     ratios of earnings to fixed charges and preferred and preference stock
     dividend requirements: (i) earnings consist of net income before deducting
     net provisions for income taxes (including deferred taxes and current
     income taxes applicable to nonoperating activities), investment tax credits
     deferred and fixed charges; (ii) fixed charges consist of interest on debt,
     amortization of debt discount, premium and expense, and the estimated
     interest component of nuclear fuel and other lease payments and rentals;
     and (iii) preferred and preference stock dividend requirements represent an
     amount equal to income, before income taxes, which would be required to
     meet the dividends on preferred and preference stocks.

                                USE OF PROCEEDS

          The proceeds of the sale of the Preferred Securities will be invested
by the Trust in the Subordinated Notes of ComEd.  ComEd will use the net
proceeds from the sale of such Subordinated Notes to pay approximately $140
million of short-term commercial paper notes issued to discharge previously
outstanding long-term debt and to pay approximately $60 million on an
outstanding bank loan.  The commercial paper bears interest at rates ranging
from 5.89% to 6.13% and the bank loan bears interest at a variable rate of
interest (currently approximately 6 1/2%).  See "Capitalization of ComEd."  For
additional information concerning ComEd's outstanding long-term debt, see the
Statements of Consolidated Capitalization in the March 31, 1995 Form 10-Q
Report.

                    DESCRIPTION OF THE PREFERRED SECURITIES

          The Preferred Securities will be issued pursuant to the terms of the
Declaration.  The Declaration will be qualified as an indenture under the Trust
Indenture Act.  The Property Trustee will act as the indenture trustee for
purposes of compliance with the provisions of the Trust Indenture Act.  The
terms of the Preferred Securities will include those stated in the Declaration
and those made part of the Declaration by the Trust Indenture Act.  The
following summary of the principal terms and provisions of the Preferred
Securities does not purport to be complete and is subject to, and qualified in
its entirety by reference to, the Declaration, a copy of which is filed as an
exhibit to the Registration Statement, of which this Prospectus is a part, the
Trust Act and the Trust Indenture Act.

GENERAL

          The Declaration authorizes the Regular Trustees, on behalf of the
Trust, to issue the Preferred Securities, which represent preferred undivided
beneficial interests in the assets of the Trust, and the Common Securities,
which represent common undivided beneficial interests in the assets of the
Trust.  All of the Common Securities will be owned by ComEd.  The Common
Securities rank pari passu, and payments will be made thereon on a pro rata
basis, with the Preferred Securities, except that upon the occurrence and during
the continuation of a Declaration Event of Default, the rights of the holders of
the Common Securities to receive payment of periodic distributions and payments
upon liquidation, redemption and otherwise will be subordinated to the rights to
payment of the holders of the Preferred Securities.  The Declaration does not
permit the issuance by the Trust of any securities other than the Trust
Securities or the incurrence of any indebtedness by the Trust.  Pursuant to the
Declaration, the Property Trustee will own and hold the Subordinated Notes for
the benefit of the holders of the Trust Securities.  The payment of
distributions out of money held by the Trust, and payments upon redemption of
the Preferred Securities or liquidation of the Trust, are guaranteed by ComEd to
the extent described under "Description of the Preferred Securities Guarantee."
The Preferred Guarantee Trustee will hold the Preferred Securities Guarantee for
the benefit of the holders of the Preferred Securities.  The Preferred
Securities Guarantee does not cover payment of distributions on the Preferred
Securities when the Trust does not have sufficient available funds in the
Property Account to make such distributions.

DISTRIBUTIONS

          Distributions on the Preferred Securities will be fixed at a rate per
annum of __% of the stated liquidation amount of $25 per Preferred Security.
Distributions in arrears will bear interest at the rate of __% per annum (to the
extent permitted by applicable law).  The term "distributions" as used herein
includes any such interest payable unless otherwise stated.

          Distributions on the Preferred Securities will be cumulative, will
accrue from _______ __, 1995 and will be payable quarterly in arrears on
March 31,  June 30, September 30 and December 31 of each year to the holders of
record on the applicable record date, commencing

                                     -14-
<PAGE>
 
September 30, 1995 when, as and if available for payment by the Property
Trustee, except as otherwise described below.  The amount of distributions
payable for any full quarterly period will be computed on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarter, on
the basis of the actual number of days elapsed in such a 90-day quarter.

          ComEd has the right under the Indenture to defer payments of interest
on the Subordinated Notes by extending the interest payment period from time to
time on the Subordinated Notes which, if exercised, would defer quarterly
distributions on the Preferred Securities (though such distributions would
continue to accrue interest since interest would continue to accrue on the
Subordinated Notes) during any such extended interest payment period.  In the
event that ComEd exercises this right, then (a) ComEd shall not declare or pay
any dividend on, make any distributions with respect to, or redeem, purchase or
make a liquidation payment with respect to, any of its capital stock, (b) ComEd
shall not make any payment of interest, principal or premium, if any, on or
repay, repurchase or redeem any debt securities (including guarantees) issued by
ComEd which rank pari passu with or junior to the Subordinated Notes, and (c)
ComEd shall not make any guarantee payments with respect to the foregoing (other
than pursuant to the Preferred Securities Guarantee).  Prior to the termination
of any such Extension Period, ComEd may further extend the interest payment
period, provided that such Extension Period, together with all such previous and
further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity of the Subordinated Notes.  Upon the termination of any
Extension Period and the payment of all amounts then due, ComEd may select a new
Extension Period as if no Extension Period had previously been declared, subject
to the above requirements.  See "Description of the Subordinated Notes --
Interest" and "-- Option to Extend Interest Payment Period."  If distributions
are deferred, the deferred distributions and accrued interest thereon shall be
paid to holders of record of the Preferred Securities, if funds are available
therefor, as they appear on the books and records of the Trust on the record
date next following the termination of such Extension Period.

          Distributions on the Preferred Securities must be paid on the dates
payable to the extent that the Trust has funds available for the payment of such
distributions in the Property Account.  The Trust's funds available for
distribution to the holders of the Preferred Securities will be limited to
payments received under the Subordinated Notes.  See "Description of the
Subordinated Notes."  The payment of distributions out of moneys held by the
Trust is guaranteed by ComEd to the extent set forth under "Description of the
Preferred Securities Guarantee."

          Distributions on the Preferred Securities will be payable to the
holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which, as long as the Preferred Securities remain in
book-entry only form, will be one Business Day (as defined herein) prior to the
relevant payment dates, which payment dates correspond to the interest payment
dates on the Subordinated Notes.  Such distributions will be paid through the
Property Trustee, who will hold amounts received in respect of the Subordinated
Notes in the Property Account for the benefit of the holders of the Trust
Securities.  Subject to any applicable laws and regulations and the provisions
of the Declaration, each such payment will be made as described under "-- Book-
Entry Only Issuance --The Depository Trust Company" below.  In the event the
Preferred Securities shall not continue to remain in book-entry only form, the
Regular Trustees shall have the right to select relevant record dates which
shall be at least one Business Day, but less than 60 Business Days, prior to the
relevant payment dates.  In the event that any date on which distributions are
to be made on the Preferred Securities is not a Business Day, then payment of
the distributions payable on such date will be made on the next succeeding day
which is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.  A
"Business Day" shall mean any day other than a day on which banking institutions
in Wilmington, Delaware or New York, New York are authorized or required by law
to close.

MANDATORY REDEMPTION

          The Subordinated Notes will mature on September 30, 2035 and may be
redeemed, in whole or in part, at any time on or after September 30, 1995, or at
any time in certain circumstances upon the occurrence of a Tax Event.  Upon the
repayment of the Subordinated Notes, whether at maturity or upon acceleration,
redemption or otherwise, the proceeds from such repayment or payment shall
simultaneously be applied to redeem Trust Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Subordinated
Notes so repaid or redeemed at the Redemption Price; provided that, except in
the case of payments upon maturity, holders of Trust Securities shall be given
not less than 30 nor more than 60 days notice of such redemption.  See
"Description of the Subordinated Notes."  In the event that fewer than all of
the outstanding Preferred Securities are to be redeemed, the Preferred
Securities will be redeemed pro rata as described under "-- Book-Entry Only
Issuance -- The Depository Trust Company" below.

SPECIAL EVENT REDEMPTION OR DISTRIBUTION

          "Tax Event" means that the Regular Trustees shall have received an
opinion from independent tax counsel experienced in such matters (a "Dissolution
Tax Opinion") to the effect that, on or after the date of this Prospectus, as a
result of (a) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein or (b) any
amendment to, or change in, an interpretation or application of such laws or
regulations by any legislative body, court, governmental agency or regulatory
authority, which amendment or change is enacted, promulgated, issued or
announced or which interpretation or pronouncement is issued or announced or
which action is taken, in each case on or after the date of this Prospectus,
there is more than an insubstantial risk that (i) the Trust would be subject to
United States federal income tax with respect to interest accrued or received on
the Subordinated Notes, (ii) interest payable to the Trust on the Subordinated
Notes would not be deductible in whole or in part by ComEd 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, which
change or amendment becomes effective on or after the date of this Prospectus.

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

          If, at any time, a Tax Event or an Investment Company Event (each, as
defined above, a "Special Event") shall occur and be continuing, the Trust
shall, except in the circumstances described below, be dissolved with the result
that Subordinated Notes with an aggregate principal amount equal to the
aggregate stated liquidation amount of, with an interest rate identical to the
distribution rate of, and accrued and unpaid interest equal to accrued and
unpaid distributions on, the Trust Securities would be distributed to the
holders of the Trust Securities, in liquidation of such holders' interests in
the Trust on a pro rata basis, within 90 days following the occurrence of such
Special Event; provided, however, that in the case of the occurrence of a Tax
Event, as a condition of such dissolution and distribution, the Regular Trustees
shall have received an opinion from independent tax counsel experienced in such
matters (a "No Recognition Opinion"), which opinion may rely on published
revenue rulings of the Internal Revenue Service, to the effect that the holders
of the Trust Securities will not recognize any gain or loss for United States
federal income tax purposes as a result of such dissolution of the Trust and the
distribution of the Subordinated Notes; and, provided, further, that,

                                     -16-
<PAGE>
 
if at the time there is available to the Trust the opportunity to eliminate,
within such 90-day period, the Special Event by taking some ministerial action,
such as filing a form or making an election, or pursuing some other similar
reasonable measure, which has no adverse effect on the Trust, ComEd or the
holders of the Trust Securities, the Trust will pursue such measure in lieu of
dissolution.  Furthermore, if in the case of the occurrence of a Tax Event, (i)
ComEd has received an opinion (a "Redemption Tax Opinion") from independent tax
counsel experienced in such matters that, as a result of a Tax Event, there is
more than an insubstantial risk that ComEd would be precluded from deducting the
interest on the Subordinated Notes for United States federal income tax purposes
even after the Subordinated Notes were distributed to the holders of Trust
Securities in liquidation of such holders' interests in the Trust as described
above or (ii) the Regular Trustees shall have been informed by such tax counsel
that a No Recognition Opinion cannot be delivered, ComEd shall have the right,
upon not less than 30 nor more than 60 days notice, to redeem the Subordinated
Notes in whole or in part for cash within 90 days following the occurrence of
such Tax Event, and, following such redemption, Trust Securities with an
aggregate liquidation amount equal to the aggregate principal amount of the
Subordinated Notes so redeemed shall be redeemed by the Trust at the Redemption
Price on a pro rata basis; provided, however, that, if at the time there is
available to ComEd or the Trust the opportunity to eliminate, within such 90-day
period, the Tax Event by taking some ministerial action, such as filing a form
or making an election, or pursuing some other similar reasonable measure which
has no adverse effect on the Trust, ComEd or the holders of the Trust
Securities, ComEd or the Trust will pursue such measure in lieu of redemption.

          If Subordinated Notes are distributed to the holders of the Preferred
Securities, ComEd will use its best efforts to have the Subordinated Notes
listed on the New York Stock Exchange or on such other exchange as the Preferred
Securities are then listed.

          After the date for any distribution of Subordinated Notes upon
dissolution of the Trust, (i) the Preferred Securities and Preferred Securities
Guarantee will no longer be deemed to be outstanding, (ii) the depositary or its
nominee, as the record holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Subordinated
Notes to be delivered upon such distribution and (iii) any certificates
representing Preferred Securities and Preferred Securities Guarantee not held by
the depositary or its nominee will be deemed to represent Subordinated Notes
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the distribution rate of, and
accrued and unpaid interest equal to accrued and unpaid distributions on, such
Preferred Securities, until such certificates are presented to ComEd or its
agent for transfer or reissuance.

          There can be no assurance as to the market prices for the Preferred
Securities or the Subordinated Notes that may be distributed in exchange for the
Preferred Securities if a dissolution and liquidation of the Trust were to
occur.  Accordingly, the Preferred Securities that an investor may purchase, or
the Subordinated Notes that the investor may receive on dissolution and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to purchase the Preferred Securities offered hereby.

REDEMPTION PROCEDURES

          The Trust may not redeem fewer than all of the outstanding Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Trust Securities for all quarterly distribution periods terminating on or prior
to the date of redemption.

          If the Trust gives a notice of redemption in respect of Preferred
Securities (which notice will be irrevocable), then, by 12:00 noon, New York
City time, on the redemption date, provided that ComEd has paid to the Property
Trustee a sufficient amount of cash in connection with the related redemption or
maturity of the Subordinated Notes, the Trust will irrevocably deposit with the

                                     -17-
<PAGE>
 
depositary funds sufficient to pay the applicable Redemption Price and will give
the depositary irrevocable instructions and authority to pay the Redemption
Price to the holders of the Preferred Securities.  See "-- Book-Entry Only
Issuance -- The Depository Trust Company."  If notice of redemption shall have
been given and funds deposited as required, then immediately prior to the close
of business on the date of such deposit, distributions will cease to accrue and
all rights of holders of such Preferred Securities so called for redemption will
cease, except the right of the holders of such Preferred Securities to receive
the Redemption Price, but without interest on such Redemption Price.  In the
event that any date fixed for redemption of Preferred Securities is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day.  In the event that payment of the Redemption
Price in respect of Preferred Securities is improperly withheld or refused and
not paid either by the Trust or by ComEd pursuant to the Preferred Securities
Guarantee, distributions on such Preferred Securities will continue to accrue,
from the original redemption date to the actual date of payment, in which case
the actual payment date will be considered the date fixed for redemption for
purposes of calculating the Redemption Price.

          In the event that fewer than all of the outstanding Preferred
Securities are to be redeemed, the Preferred Securities will be redeemed pro
rata as described under "-- Book-Entry Only Issuance -- The Depository Trust
Company" below.

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

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

          In the event of any voluntary or involuntary dissolution, winding-up
or termination of the Trust, the holders of the Preferred Securities at that
time will be entitled to receive out of the assets of the Trust, after
satisfaction of liabilities to creditors, distributions in an amount equal to
the aggregate of the stated liquidation amount of $25 per Preferred Security
plus accrued and unpaid distributions thereon to the date of payment (the
"Liquidation Distribution"), unless, in connection with such dissolution,
winding-up or termination, Subordinated Notes in an aggregate principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the distribution rate of, and accrued and unpaid interest equal to
accrued and unpaid distributions on, the Preferred Securities have been
distributed on a pro rata basis to the holders of Preferred Securities in
exchange for such Preferred Securities.

          If, upon any such dissolution, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by the Trust on the Preferred Securities shall be paid on a pro rata basis.  The
holders of the Common Securities will be entitled to receive distributions upon
any such dissolution pro rata with the holders of the Preferred Securities,
except that if a Declaration Event of Default has occurred and is continuing,
the Preferred Securities shall have a preference over the Common Securities.

          Pursuant to the Declaration, the Trust shall terminate (i) on
________, the expiration of the term of the Trust, (ii) upon the bankruptcy of
ComEd, (iii) upon the filing of a certificate of dissolution or its equivalent
with respect to ComEd, the filing of a certificate of cancellation with respect
to the Trust, or the revocation of the charter of ComEd and the expiration of 90
days after the date of revocation without a reinstatement thereof, (iv) upon the
distribution of the Subordinated Notes

                                     -18-
<PAGE>
 
following the occurrence of a Special Event, (v) upon the entry of a decree of a
judicial dissolution of ComEd or the Trust or (vi) upon the redemption of all of
the Trust Securities.

DECLARATION EVENTS OF DEFAULT

          An event of default under the Indenture (an "Indenture Event of
Default") (see "Description of the Subordinated Notes -- Indenture Events of
Default") constitutes an event of default under the Declaration with respect to
the Trust Securities (a "Declaration Event of Default"), provided that pursuant
to the Declaration, the holder of the Common Securities will be deemed to have
waived any Declaration Event of Default with respect to the Common Securities or
its consequences until all Declaration Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated.  Until
such Declaration Events of Default with respect to the Preferred Securities have
been so cured, waived or otherwise eliminated, the Property Trustee will be
deemed to be acting solely on behalf of the holders of the Preferred Securities
and only the holders of the Preferred Securities will have the right to direct
the Property Trustee with respect to certain matters under the Declaration, and
therefore the Indenture.

          Upon the occurrence of a Declaration Event of Default, the Property
Trustee, as the sole holder of the Subordinated Notes, will have the right under
the Indenture to declare the principal of, and interest on, the Subordinated
Notes to be immediately due and payable.

VOTING RIGHTS

          Except as provided below, under the Trust Act, the Trust Indenture Act
and under "Description of the Preferred Securities Guarantee -- Amendments and
Assignment" and as otherwise required by law and the Declaration, the holders of
the Preferred Securities will have no voting rights.

          The holders of a majority in aggregate liquidation amount of the
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee, or
to direct the exercise of any trust or power conferred upon the Property Trustee
under the Declaration, including the right to direct the Property Trustee, as
the holder of the Subordinated Notes, to (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Debt Trustee (as
hereinafter defined) under the Indenture with respect to the Subordinated Notes,
(ii) waive any past Indenture Event of Default which is waivable under the Base
Indenture (as defined herein), (iii) exercise any right to rescind or annul a
declaration that the principal of all the Subordinated Notes shall be due and
payable, or (iv) consent to any amendment, modification or termination of the
Indenture or the Subordinated Notes, where such consent shall be required,
provided that where a consent under the Indenture would require the consent of
more than a majority of the holders in principal amount of Subordinated Notes
affected thereby (a "Super-Majority"), only the holders of at least the
proportion in liquidation amount of the Preferred Securities which the relevant
Super-Majority represents of the aggregate principal amount of the Subordinated
Notes, may direct the Property Trustee to give such consent.  If the Property
Trustee fails to enforce its rights under the Declaration, a holder of Preferred
Securities may, after a period of 30 days has elapsed from such holder's written
request to the Property Trustee to enforce such rights, institute a legal
proceeding directly against any person to enforce the Property Trustee's rights
under the Declaration without first instituting any legal proceeding against the
Property Trustee or any other person or entity.  The Property Trustee shall
notify all holders of the Preferred Securities of any notice of default received
from the Debt Trustee with respect to the Subordinated Notes.  Such notice shall
state that such Indenture Event of Default also constitutes a Declaration Event
of Default.  The Property Trustee shall not take any action described in clauses
(i), (ii),  (iii) or (iv) above unless the Property Trustee has obtained an
opinion of independent tax counsel to the effect that, as a result of such
action, the Trust will not be classified as other than a grantor trust for
United States federal

                                     -19-
<PAGE>
 
income tax purposes and each holder of Trust Securities will be treated as
owning an undivided beneficial interest in the Subordinated Notes.

          In the event the consent of the Property Trustee, as the holder of the
Subordinated Notes, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture, the Property Trustee
shall request the direction of the holders of the Trust Securities with respect
to such amendment, modification or termination.  The Property Trustee shall vote
with respect to such amendment, modification or termination as directed by a
majority in liquidation amount of the Preferred Securities and, if no
Declaration Event of Default has occurred and is continuing, a majority in
liquidation amount of the Common Securities, voting together as separate
classes, provided that where a consent under the Indenture would require the
consent of a Super-Majority, the Property Trustee may only give such consent at
the direction of the holders of at least the proportion in liquidation amount of
the Preferred Securities and Common Securities, respectively, which the relevant
Super-Majority represents of the aggregate principal amount of the Subordinated
Notes outstanding.  The Property Trustee shall not take any such action in
accordance with the directions of the holders of the Trust Securities unless the
Property Trustee has obtained an opinion of independent tax counsel to the
effect that, as a result of such action,  the Trust will not be classified as
other than a grantor trust for United States federal income tax purposes.

          A waiver of an Indenture Event of Default will constitute a waiver of
the corresponding Declaration Event of Default.

          Any required approval or direction of holders of Preferred Securities
may be given at a separate meeting of holders of Preferred Securities convened
for such purpose, at a meeting of all of the holders of Trust Securities or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such holders is to be taken, to
be mailed to each holder of record of Preferred Securities.  Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.  No vote or consent of the holders of
Preferred Securities will be required for the Trust to redeem and cancel
Preferred Securities or distribute Subordinated Notes in accordance with the
Declaration.

          Notwithstanding that holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities at such time that are owned by ComEd or any entity directly
or indirectly controlling or controlled by, or under direct or indirect common
control with, ComEd shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

          The procedures by which holders of Preferred Securities may exercise
their voting rights are described below.  See "-- Book-Entry Only Issuance --
The Depository Trust Company."

          Holders of the Preferred Securities will have no rights to appoint or
remove the ComEd Trustees, who may be appointed, removed or replaced solely by
ComEd, as the direct or indirect holder of all the Common Securities.

MODIFICATION OF THE DECLARATION

          The Declaration may be amended or modified if approved and executed by
a majority of the Regular Trustees, provided that if any proposed amendment
provides for, or the Regular Trustees otherwise propose to effect, (i) any
action that would adversely affect the powers, preferences or special rights of
the Trust Securities, whether by way of amendment to the Declaration or
otherwise

                                     -20-
<PAGE>
 
or (ii) the dissolution, winding-up or termination of the Trust other than
pursuant to the terms of the Declaration, then the holders of the Trust
Securities as a single class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of at least 66-2/3 in liquidation amount of the Trust Securities
affected thereby, provided that a reduction of the principal amount or the
distribution rate, or a change in the payment dates or maturity of the Preferred
Securities, shall not be permitted without the consent of each holder of
Preferred Securities.  In the event any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or the
Common Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of 66-2/3 in liquidation amount of such class of Trust
Securities.

          Notwithstanding the foregoing, no amendment or modification may be
made to the Declaration if such amendment or modification would (i) cause the
Trust to be classified for purposes of United States federal income taxation as
other than a grantor trust, (ii) reduce or otherwise adversely affect the powers
of the Property Trustee or (iii) cause the Trust to be deemed to be an
"investment company" which is required to be registered under the 1940 Act.

MERGERS, CONSOLIDATIONS OR AMALGAMATIONS

          The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except as
described below.  The Trust may, with the consent of a majority of the Regular
Trustees and without the consent of the holders of the Trust Securities,
consolidate, amalgamate, merge with or into, or be replaced by a trust organized
as such under the laws of any State; provided, that (i) such successor entity
either (x) expressly assumes all of the obligations of the Trust with respect to
the Trust Securities or (y) substitutes for the Trust Securities other
securities having substantially the same terms as the Trust Securities (the
"Successor Securities") so long as the Successor Securities rank the same as the
Trust Securities rank in priority with respect to distributions and payments
upon liquidation, redemption, maturity and otherwise, (ii) ComEd expressly
acknowledges a trustee of such successor entity which possesses the same powers
and duties as the Property Trustee as the holder of the Subordinated Notes,
(iii) the Preferred Securities or any 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 Preferred
Securities are then listed, (iv) such merger, consolidation, amalgamation or
replacement does not cause the Preferred Securities (including any Successor
Securities) to be downgraded by any nationally recognized statistical rating
organization, (v) such merger, consolidation, amalgamation or replacement does
not adversely affect the rights, preferences and privileges of the holders of
the Trust Securities (including any Successor Securities) in any material
respect (other than with respect to any dilution of the holders' interest in the
new entity), (vi) such successor entity has a purpose identical to that of the
Trust, (vii) prior to such merger, consolidation, amalgamation or replacement,
ComEd has received an opinion from independent counsel to the Trust experienced
in such matters to the effect that (A) such merger, consolidation, amalgamation
or replacement does not adversely affect the rights, preferences and privileges
of the holders of the Trust Securities (including any Successor Securities) in
any material respect (other than with respect to any dilution of the holders'
interest in the new entity), and (B) following such merger, consolidation,
amalgamation or replacement, neither the Trust nor such successor entity will be
required to register as an investment company under the 1940 Act and (viii)
ComEd guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Preferred Securities
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 any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger or replacement would
cause the Trust or the successor entity to be classified

                                     -21-
<PAGE>
 
for United States federal income tax purposes as other than a grantor trust and
each holder of Trust Securities not to be treated as owning an undivided
beneficial interest in the Subordinated Notes.

BOOK-ENTRY ONLY ISSUANCE - THE DEPOSITORY TRUST COMPANY

          The Depository Trust Company ("DTC") will act as securities depositary
for the Preferred Securities.  The Preferred Securities will be issued only as
fully registered securities registered in the name of Cede & Co. (DTC's
nominee).  One or more fully registered global Preferred Securities certificates
will be issued, representing in the aggregate the total number of Preferred
Securities, and will be deposited with DTC.

          The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form.  Such laws
may impair the ability to transfer beneficial interests in a global Preferred
Security.

          DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "Clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act.  DTC
holds securities that its participants ("Participants") deposit with DTC.  DTC
also facilitates the settlement among Participants of securities transactions,
such as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates.  Direct Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations ("Direct Participants").  DTC is
owned by a number of its Direct Participants and by the New York Stock Exchange,
the American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc.  Access to the DTC system is also available to others such as
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants").  The rules applicable to DTC and its
Participants are on file with the Commission.

          Purchases of Preferred Securities within the DTC system must be made
by or through Direct Participants, which will receive a credit for the Preferred
Securities on DTC's records.  The ownership interest of each actual purchaser of
Preferred Securities ("Beneficial Owner") is in turn to be recorded on the
Direct and Indirect Participants' records.  Beneficial Owners will not receive
written confirmation from DTC of their purchases, but Beneficial Owners are
expected to receive written confirmations providing details of the transactions,
as well as periodic statements of their holdings, from the Direct or Indirect
Participants through which the Beneficial Owners purchased Preferred Securities.
Transfers of ownership interests in the Preferred Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners.  Beneficial Owners will not receive certificates representing
their ownership interests in Preferred Securities, except in the event that use
of the book-entry system for the Preferred Securities is discontinued.

          To facilitate subsequent transfers, all the Preferred Securities
deposited by Participants with DTC are registered in the name of DTC's nominee,
Cede & Co. The deposit of Preferred Securities with DTC and their registration
in the name of Cede & Co. effect no change in beneficial ownership.  DTC has no
knowledge of the actual Beneficial Owners of the Preferred Securities.  DTC's
records reflect only the identity of the Direct Participants to whose accounts
such Preferred Securities are credited, which may or may not be the Beneficial
Owners.  The Participants will remain responsible for keeping account of their
holdings on behalf of their customers.

          Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to

                                     -22-
<PAGE>
 
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

          Redemption notices shall be sent to Cede & Co. If less than all of the
Preferred Securities are being redeemed, DTC will reduce pro rata the amount of
the interest of each Direct Participant in the Preferred Securities to be
redeemed; provided that if, as a result of such pro rata redemption, Direct
Participants would hold fractional interests in the Preferred Securities, DTC
will adjust the amount of the interest of each Direct Participant to be redeemed
to avoid such fractional interests.

          Although voting with respect to the Preferred Securities is limited,
in those cases where a vote is required neither DTC nor Cede & Co. will itself
consent or vote with respect to Preferred Securities.  Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date.  The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Direct Participants to whose accounts the Preferred
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).

          Distribution payments on the Preferred Securities will be made to DTC.
DTC's practice is to credit Direct Participants' accounts on the relevant
payment date in accordance with their respective holdings shown on DTC's records
unless DTC has reason to believe that it will not receive payments on such
payment date.  Payments by participants to Beneficial Owners will be governed by
standing instructions and customary practices, as in the case with securities
held for the account of customers in bearer form or registered in "street name,"
and will be the responsibility of such Participant and not of DTC, the Trust,
any trustee or ComEd, subject to any statutory or regulatory requirements as may
be in effect from time to time.  Payment of distributions to DTC is the
responsibility of the Trust, disbursement of such payments to Direct
Participants is the responsibility of DTC, and disbursement of such payments to
the Beneficial Owners is the responsibility of Direct and Indirect Participants.

          Except as provided herein, a Beneficial Owner in a global Preferred
Security will not be entitled to receive physical delivery of Preferred
Securities.  Accordingly, each Beneficial Owner must rely on the procedures of
DTC to exercise any rights under the Preferred Securities.

          DTC may discontinue providing its services as securities depositary
with respect to the Preferred Securities at any time by giving reasonable notice
to the Trust.  Under such circumstances, in the event that a successor
securities depositary is not obtained, Preferred Securities certificates are
required to be printed and delivered.  Additionally, the Regular Trustees (with
the consent of ComEd) may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor depositary) with respect to the Preferred
Securities.  In that event, certificates for the Preferred Securities will be
printed and delivered.

          The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that ComEd and the Trust believe to be
reliable, but ComEd and the Trust take no responsibility for the accuracy
thereof.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

          The Property Trustee, prior to the occurrence of a default with
respect to the Trust Securities and after the curing of all such defaults that
may have occurred, undertakes to perform only such duties as are specifically
set forth in the Declaration and, after default, shall exercise the same degree
of care as a prudent individual would exercise in the conduct of his or her own
affairs.  Subject to such provisions, the Property Trustee is under no
obligation to exercise any of the powers vested in it by the Declaration at the
request of any holder of Preferred Securities, unless offered reasonable

                                     -23-
<PAGE>
 
indemnity by such holder against the costs, expenses and liabilities which might
be incurred thereby; but the foregoing shall not relieve the Property Trustee,
upon the occurrence of a Declaration Event of Default, from exercising the
rights and powers vested in it by the Declaration.  The Property Trustee also
serves as trustee under the Preferred Securities Guarantee.

REGISTRAR AND TRANSFER AGENT

          In the event that the Preferred Securities do not remain in book-entry
only form, the Property Trustee will act as paying agent and may designate an
additional or substitute paying agent at any time.  Registration of transfers of
Preferred Securities will be effected without charge by or on behalf of the
Trust, but upon payment (with the giving of such indemnity as the Regular
Trustees may require) in respect of any tax or other government charges which
may be imposed in relation to it.  The Trust will not be required to register or
cause to be registered the transfer of Preferred Securities after such Preferred
Securities have been called for redemption.

GOVERNING LAW

          The Declaration and the Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.

MISCELLANEOUS

          The Regular Trustees are authorized and directed to operate the Trust
in such a way so that the Trust will not be deemed to be an "investment company"
required to be registered under the 1940 Act or characterized for United States
federal income tax purposes as other than a grantor Trust.  ComEd is authorized
and directed to conduct its affairs so that the Subordinated Notes will be
treated as indebtedness of ComEd for United States federal income tax purposes.
In this connection, the Regular Trustees and ComEd are authorized to take any
action, not inconsistent with applicable law, the restated articles of
incorporation of ComEd, that each of the Regular Trustees and ComEd determines
in their discretion to be necessary or desirable for such purposes, as long as
such action does not materially and adversely affect the interests of the
holders of the Preferred Securities.


               DESCRIPTION OF THE PREFERRED SECURITIES GUARANTEE

          Set forth below is a summary of information concerning the Preferred
Securities Guarantee that will be executed and delivered by ComEd for the
benefit of the holders from time to time of the Preferred Securities.  The
Preferred Securities Guarantee will be qualified as an indenture under the Trust
Indenture Act.  Wilmington Trust Company will act as the Preferred Guarantee
Trustee.  The terms of the Preferred Securities Guarantee will be those set
forth therein and those made part thereof by the Trust Indenture Act.  The
following summary does not purport to be complete and is subject in all respects
to the provisions of, and is qualified in its entirety by reference to, the
Preferred Securities Guarantee, which is filed as an exhibit to the Registration
Statement of which this Prospectus forms a part and the Trust Indenture Act.
The Preferred Securities will be held by the Preferred Guarantee Trustee for the
benefit of the holders of the Preferred Securities.

GENERAL

          Pursuant to the Preferred Securities Guarantee, ComEd will irrevocably
and unconditionally agree, to the extent set forth therein, to pay in full to
the holders of the Preferred Securities the Guarantee Payments (as defined
herein) (without duplication of amounts theretofore paid by the Trust), to the
extent not paid by the Trust, regardless of any defense, right of set-off or
counterclaim that the Trust may have or assert.  The following payments or
distributions with respect

                                     -24-
<PAGE>
 
to the Preferred Securities to the extent not paid or made by the Trust (the
"Guarantee Payments") will be subject to the Preferred Securities Guarantee
(without duplication): (i) any accrued and unpaid distributions that are
required to be paid on the Preferred Securities, to the extent the Trust has
funds available therefor, (ii) the Redemption Price, including all accrued and
unpaid distributions to the date of the redemption, to the extent the Trust has
funds available therefor, with respect to any Preferred Securities called for
redemption by the Trust and (iii) upon a voluntary or involuntary dissolution,
winding-up or termination of the Trust (other than in connection with the
distribution of Subordinated Notes to the holders of Preferred Securities in
exchange for Preferred Securities), the lesser of (a) the aggregate of the
liquidation amount and all accrued and unpaid distributions on the Preferred
Securities to the date of payment and (b) the amount of assets of the Trust
remaining available for distribution to holders of Preferred Securities in
liquidation of the Trust. ComEd's obligation to make a Guarantee Payment may be
satisfied by direct payment of the required amounts by ComEd to the holders of
Preferred Securities or by causing the Trust to pay such amounts to such
holders.

          The Preferred Securities Guarantee will be a full and unconditional
guarantee of the Guarantee Payments with respect to the Preferred Securities
from the time of issuance of the Preferred Securities, but will not apply to the
payment of distributions and other payments on the Preferred Securities when the
Property Trustee does not have sufficient funds in the Property Account to make
such distributions or other payments.  If ComEd does not make interest payments
on the Subordinated Notes held by the Property Trustee, the Trust will not make
distributions on the Preferred Securities issued by the Trust and will not have
funds available therefor.  See "Description of the Subordinated Notes -- Certain
Covenants."

          ComEd has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Trust with respect to the Common Securities
(the "Common Securities Guarantee") to the same extent as the Preferred
Securities Guarantee, except that upon the occurrence and during the
continuation of an Indenture Event of Default, holders of Preferred Securities
shall have priority over holders of Common Securities with respect to
distributions and payments on liquidation, redemption or otherwise.

CERTAIN COVENANTS OF COMED

          In the Preferred Securities Guarantee, ComEd will covenant that, so
long as the Preferred Securities remain outstanding, if there shall have
occurred and is continuing any event that would constitute an event of default
under the Preferred Securities Guarantee or the Declaration, then (a) ComEd
shall not declare or pay any dividend on, or make any distribution with respect
to, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of its capital stock, and (b) ComEd shall not make any payment of interest,
principal or premium, if any, on or repay, repurchase or redeem any debt
securities (including guarantees) issued by ComEd which rank pari passu with or
junior to the Subordinated Notes.

AMENDMENTS AND ASSIGNMENT

          Except with respect to any changes which do not materially adversely
affect the rights of holders of Preferred Securities (in which case no vote will
be required), the Preferred Securities Guarantee may be amended only with the
prior approval of the holders of not less than 66-2/3% in liquidation amount of
the outstanding Preferred Securities.  The manner of obtaining any such approval
of holders of the Preferred Securities is set forth under "Description of the
Preferred Securities -- Voting Rights."  All guarantees and agreements contained
in the Preferred Securities Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of ComEd and shall inure to the benefit
of the Preferred Guarantee Trustee and the holders of the Preferred Securities
then outstanding.

TERMINATION OF THE PREFERRED SECURITIES GUARANTEE

          The Preferred Securities Guarantee will terminate and be of no further
force and effect as to the Preferred Securities upon full payment of the
Redemption Price of all Preferred Securities, or upon distribution of the
Subordinated Notes to the holders of the Preferred Securities, and will
terminate completely upon full payment of the amounts payable upon liquidation
of the Trust.  See "Description of the Subordinated Notes -- Events of Default"
for a description of the events of default and enforcement rights of the holders
of Subordinated Notes.  The Preferred Securities Guarantee will continue to be
effective or will be reinstated, as the case may be, if at any time any holder
of Preferred Securities must repay to the Trust or ComEd, or their successors,
any sums paid to them under such Preferred Securities or the Preferred
Securities Guarantee.

EVENTS OF DEFAULT

          An event of default under the Preferred Securities Guarantee will
occur upon the failure of ComEd to perform any of its payment or other
obligations thereunder.

          The holders of a majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of the Preferred Securities Guarantee or to direct the exercise of any
trust or power conferred upon the Preferred Guarantee Trustee under the
Preferred Securities Guarantee.  If the Preferred Guarantee Trustee fails to
enforce the Preferred Securities Guarantee, any holder of Preferred Securities
may institute a legal proceeding directly against ComEd to enforce the Preferred
Guarantee Trustee's rights under the Preferred Securities Guarantee, without
first instituting a legal proceeding against the Trust, the Preferred Guarantee
Trustee or any other person or entity.

STATUS OF THE PREFERRED SECURITIES GUARANTEE

          ComEd's obligations under the Preferred Securities Guarantee to make
the Guarantee Payments will constitute an unsecured obligation of ComEd and will
rank (i) subordinate and junior in right of payment to all other liabilities of
ComEd, including the Subordinated Notes, except those liabilities of ComEd made
pari passu or subordinate by their terms, (ii) pari passu with the most senior
preferred stock now or hereafter issued by ComEd and with any guarantee now or
hereafter entered into by ComEd in respect of any preferred stock of any
affiliate of ComEd, and (iii) senior to ComEd's common stock.  The terms of the
Preferred Securities provide that each holder of Preferred Securities by
acceptance thereof agrees to the subordination provisions and other terms of the
Preferred Securities Guarantee.

          The Preferred Securities Guarantee will constitute a guarantee of
payment and not of collection (that is, the guaranteed party may institute a
legal proceeding directly against the guarantor to enforce its rights under the
guarantee without instituting a legal proceeding against any other person or
entity).  The Preferred Securities Guarantee will be deposited with the
Preferred Guarantee Trustee to be held for the benefit of the holders of the
Preferred Securities.  Except as otherwise noted herein, the Preferred Guarantee
Trustee has the right to enforce the Preferred Securities Guarantee on behalf of
the holders of the Preferred Securities.  The Preferred Securities Guarantee
will not be discharged except by payment of the Guarantee Payments in full
(without duplication of amounts theretofore paid by the Trust).

INFORMATION CONCERNING THE PREFERRED GUARANTEE TRUSTEE

          The Preferred Guarantee Trustee, prior to the occurrence of a default
with respect to the Preferred Securities Guarantee and after the curing of all
such defaults that may have occurred, undertakes to perform only such duties as
are specifically set forth in the Preferred Securities

                                     -26-
<PAGE>
 
Guarantee and, after default, shall exercise the same degree of care as a
prudent individual would exercise in the conduct of his or her own affairs.
Subject to such provisions, the Preferred Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by the  Preferred
Securities Guarantee at the request of any holder of Preferred Securities,
unless offered reasonable indemnity against the costs, expenses and liabilities
which might be incurred thereby; but the foregoing shall not relieve the
Preferred Guarantee Trustee, upon the occurrence of an event of default under
the Preferred Securities Guarantee, from exercising the rights and powers vested
in it by the Preferred Securities Guarantee.  The Preferred Guarantee Trustee
also serves as Property Trustee.

GOVERNING LAW
 
          The Preferred Securities Guarantee will be governed by, and construed
in accordance with, the internal laws of the State of New York.


                     DESCRIPTION OF THE SUBORDINATED NOTES

          Set forth below is a description of the terms of the Subordinated
Notes.  The following description does not purport to be complete and is subject
to, and is qualified in its entirety by reference to, the Indenture (the "Base
Indenture"), dated as of July __, 1995, between ComEd and Wilmington Trust
Company, as Trustee (the "Debt Trustee"), as supplemented by a First
Supplemental Indenture, dated as of ________, 1995 (the Base Indenture, as so
supplemented, is hereinafter referred to as the "Indenture"), the forms of which
are filed as an exhibit to the Registration Statement of which this Prospectus
forms a part.  The terms of the Subordinated Notes will include those stated in
the Indenture and those made a part of the Indenture by reference to the Trust
Indenture Act.  Certain capitalized terms used herein are defined in the
Indenture.

          Under certain circumstances involving the dissolution of the Trust
following the occurrence of a Special Event, Subordinated Notes may be
distributed to the holders of Trust Securities in liquidation of the Trust.  See
"Description of the Preferred Securities -- Special Event Redemption or
Distribution."

          If the Subordinated Notes are distributed to the holders of the Trust
Securities, ComEd will use its best efforts to have the Subordinated Notes
listed on the New York Stock Exchange or on such other exchange as the Preferred
Securities are then listed.

GENERAL

          The Subordinated Notes will be issued as unsecured subordinated debt
securities under the Indenture.  The Subordinated Notes will be limited in
aggregate principal amount to approximately $206.2 million, such amount being
the sum of the aggregate stated liquidation amount of the Preferred Securities
and the capital contributed by ComEd in exchange for the Common Securities (the
"Payment").

          The Subordinated Notes are not subject to a sinking fund provision.
The entire principal amount of the Subordinated Notes will mature and become due
and payable, together with any accrued and unpaid interest thereon, including
Additional Interest (as defined herein), if any, on September 30, 2035.

          If Subordinated Notes are distributed to holders of the Preferred
Securities in liquidation of such holders' interests in the Trust, such
Subordinated Notes will initially be issued as a Global Security (as defined
below).  As described herein, under certain limited circumstances, Subordinated
Notes may be issued in certificated form in exchange for a Global Security.  See
"--Book Entry and Settlement." In the event Subordinated Notes are issued in
certificated form, such Subordinated Notes

                                     -27-
<PAGE>
 
will be in denominations of $25 and integral multiples thereof and may be
transferred or exchanged at the offices described below.  Payments on
Subordinated Notes issued as a Global Security will be made to the depositary
for the Subordinated Notes.  In the event Subordinated Notes are issued in
certificated form, principal and interest will be payable, the transfer of the
Subordinated Notes will be registrable and Subordinated Notes will be
exchangeable for Subordinated Notes of other denominations of a like aggregate
principal amount at the corporate trust office of the Debt Trustee in
____________, _____________; provided, that payment of interest may be made at
the option of ComEd by check mailed to the address of the persons entitled
thereto.

          The Indenture does not contain provisions that afford holders of the
Subordinated Notes protection in the event of a highly leveraged transaction
involving ComEd.

SUBORDINATION

          The Indenture provides that the Subordinated Notes are subordinated
and junior in right of payment to all Senior Indebtedness of ComEd, whether now
existing or hereafter incurred.  No payment of principal of (including
redemption payments, if any), premium, if any, or interest on, the Subordinated
Notes may be made if (a) any Senior Indebtedness of ComEd is not paid when due
and any applicable grace period with respect to such default has ended with such
default not being cured or waived or ceasing to exist, or (b) the maturity of
any Senior Indebtedness has been accelerated because of a default.  Upon any
distribution of assets of ComEd to creditors upon any dissolution, winding-up,
liquidation or reorganization, whether voluntary or involuntary, or in
bankruptcy, insolvency, receivership or other proceedings, all principal of,
premium, if any, and interest due or to become due on, all Senior Indebtedness
must be paid in full before the holders of the Subordinated Notes are entitled
to receive or retain any payment.  The rights of the holders of the Subordinated
Notes will be subrogated to the rights of the holders of Senior Indebtedness to
receive payments or distributions applicable to such Senior Indebtedness until
all amounts owing on the Subordinated Notes are paid in full.

          The term "Senior Indebtedness" means (i) any payment in respect of (a)
indebtedness of ComEd for money borrowed and (b) indebtedness evidenced by
securities, debentures, bonds, notes or other similar instruments issued by
ComEd including, without limitation, indebtedness evidenced by securities issued
pursuant to its Mortgage dated July 1, 1923, as supplemented, and indentures
with various trustees (other than the Indenture); (ii) all capital lease
obligations of ComEd; (iii) all obligations of ComEd issued or assumed as the
deferred purchase price of property, all conditional sale obligations of ComEd
and all obligations of ComEd under any title retention agreement (but excluding
trade accounts payable arising in the ordinary course of business); (iv) all
obligations of ComEd for the reimbursement on any letter of credit, banker's
acceptance, security purchase facility or similar credit transaction; (v) all
obligations of the type referred to in clauses (i) through (iv) above of other
persons for the payment of which ComEd is responsible or liable as obligor,
guarantor or otherwise; and (vi) all obligations of the type referred to in
clauses (i) through (v) above of other persons secured by any lien on any
property or asset of ComEd (whether or not such obligation is assumed by ComEd),
except for (1) any such indebtedness that is by its terms subordinated to or
pari passu with the Subordinated Notes, as the case may be, including all other
debt securities and guarantees in respect of those debt securities, issued to
any other trusts, partnerships or other entities affiliated with ComEd which act
as a financing vehicle of ComEd in connection with the issuance of preferred
securities by such entity or other securities which rank pari passu with, or
junior to, the Preferred Securities, and (2) any indebtedness between or among
ComEd and its affiliates.  Such Senior Indebtedness shall continue to be Senior
Indebtedness and be entitled to the benefits of the subordination provisions
irrespective of any amendment, modification or waiver of any term of such Senior
Indebtedness.

                                     -28-
<PAGE>
 
          The Indenture does not limit the aggregate amount of Senior
Indebtedness which may be issued by ComEd.  As of June 30, 1995, Senior
Indebtedness of ComEd aggregated approximately $8,231 million.

CERTAIN COVENANTS

          If (i) there shall have occurred any event that would constitute an
Indenture Event of Default or (ii) ComEd shall be in default with respect to its
payment of any obligations under the Preferred Securities Guarantee or the
Common Securities Guarantee, then (a) ComEd shall not declare or pay any
dividend on, make any distributions with respect to, or redeem, purchase or make
a liquidation payment with respect to, any of its capital stock, (b) ComEd shall
not make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by ComEd which rank pari passu
with or junior to the Subordinated Notes and (c) ComEd shall not make any
guarantee payments with respect to the foregoing (other than pursuant to the
Preferred Securities Guarantee).

          If ComEd shall have given notice of its election of an Extension
Period as provided in the Indenture and such period, or any extension thereof,
shall be continuing, then (a) ComEd shall not declare or pay any dividend on,
make any distributions with respect to, or redeem, purchase or make a
liquidation payment with respect to, any of its capital stock, (b) ComEd shall
not make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities (including guarantees) issued by ComEd
which rank pari passu with or junior to the Subordinated Notes and (c) ComEd
shall not make any guarantee payments with respect to the foregoing (other than
pursuant to the Preferred Securities Guarantee).

          For so long as the Trust Securities remain outstanding, ComEd will
covenant (i) to directly or indirectly maintain 100% direct or indirect
ownership of the Common Securities of the Trust; provided, however, that any
permitted successor of ComEd under the Indenture may succeed to ComEd's
ownership of such Common Securities, (ii) not to cause, as sponsor of the Trust,
or to permit, as holder of the Common Securities, the dissolution, winding-up or
termination of the Trust, except in connection with a distribution of the
Subordinated Notes as provided in the Declaration and in connection with certain
mergers, consolidations or amalgamations and (iii) to use its reasonable efforts
to cause the Trust (a) to remain a statutory business trust, except in
connection with the distribution of Subordinated Notes to the holders of Trust
Securities in liquidation of the Trust, the redemption of all of the Trust
Securities of the Trust, or certain mergers, consolidations or amalgamations,
each as permitted by the Declaration, and (b) to otherwise continue to be
classified as a grantor trust for United States federal income purposes.

OPTIONAL REDEMPTION

          ComEd shall have the right to redeem the Subordinated Notes, in whole
or in part, from time to time, on or after September 30, 2000, or at any time in
certain circumstances upon the occurrence of a Tax Event as described under
"Description of the Preferred Securities -- Special Event Redemption or
Distribution," upon not less than 30 nor more than 60 days' notice, at a
Redemption Price equal to 100% of the principal amount to be redeemed plus any
accrued and unpaid interest, including Additional Interest, if any, to the
redemption date.  If a partial redemption of the Preferred Securities resulting
from a partial redemption of the Subordinated Notes would result in the
delisting of the Preferred Securities, ComEd may only redeem the Subordinated
Notes in whole.

INTEREST

          Each Subordinated Note shall bear interest at the rate of  ____% per
annum from the original date of issuance, payable quarterly in arrears on March
31, June 30, September 30 and

                                     -29-
<PAGE>
 
December 31 of each year (each, an "Interest Payment Date"), commencing
September 30, 1995, to the person in whose name such Subordinated Note is
registered, subject to certain exceptions, at the close of business on the
Business Day next preceding such Interest Payment Date.  In the event the
Subordinated Notes shall not continue to remain in book-entry only form, ComEd
shall have the right to select record dates which shall be not less than fifteen
days prior to each Interest Payment Date.

          The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  The amount of interest payable
for any period shorter than a full quarterly period will be computed on the
basis of the actual number of days elapsed in such 90-day quarter.  In the event
that any date on which interest is payable on the Subordinated Notes is not a
Business Day, then payment of the interest payable on such date will be made on
the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay), except that, if such Business Day
is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date.


OPTION TO EXTEND INTEREST PAYMENT PERIOD

          ComEd shall have the right at any time, and from time to time, during
the term of the Subordinated Notes to defer payments of interest by extending
the interest payment period for a period not exceeding 20 consecutive quarters,
at the end of which Extension Period, ComEd shall pay all interest then accrued
and unpaid (including any Additional Interest, together with interest thereon at
the rate specified for the Subordinated Notes to the extent permitted by
applicable law); provided, that, during any such Extension Period, (a) ComEd
shall not declare or pay any dividend on, make any distributions with respect
to, or redeem, purchase or make a liquidation payment with respect to, any of
its capital stock, (b) ComEd shall not make any payment of interest, principal
or premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees) issued by ComEd which rank pari passu with or junior to
the Subordinated Notes and (c) ComEd shall not make any guarantee payments with
respect to the foregoing (other than pursuant to the Preferred Securities
Guarantee).  Prior to the termination of any such Extension Period, ComEd may
further defer payments of interest by extending the interest payment period,
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters or extend beyond the
maturity of the Subordinated Notes.  Upon the termination of any Extension
Period and the payment of all amounts then due, ComEd may select a new Extension
Period, as if no Extension Period had previously been declared, subject to the
above requirements.  No interest during an Extension Period, except at the end
thereof, shall be due and payable.  ComEd has no present intention of exercising
its rights to defer payments of interest by extending the interest payment
period on the Subordinated Notes.  If the Property Trustee shall be the sole
holder of the Subordinated Notes, ComEd shall give the Regular Trustees and the
Property Trustee notice of its selection of such Extension Period one Business
Day prior to the earlier of (i) the next succeeding date on which distributions
on the Preferred Securities are payable or (ii) the date the Trust is required
to give notice to the New York Stock Exchange or other applicable self-
regulatory organization or to holders of the Preferred Securities of the record
date or the date such distribution is payable, but in any event not less than
one Business Day prior to such record date.  The Regular Trustees shall give
notice of ComEd's selection of such Extension Period to the holders of the
Preferred Securities.  If the Property Trustee shall not be the sole holder of
the Subordinated Notes, ComEd shall give the holders of the Subordinated Notes
notice of its selection of such Extension Period ten Business Days prior to the
earlier of (i) the Interest Payment Date or (ii) the date ComEd is required to
give notice to the New York Stock Exchange or other applicable self-regulatory
organization or to holders of the Subordinated Notes of the record or payment
date of such related interest payment, but in any event at least two Business
Days before such record date.

                                     -30-
<PAGE>
 
ADDITIONAL INTEREST

          If at any time the Trust shall be required to pay any taxes, duties,
assessments or governmental charges of whatever nature (other than withholding
taxes) imposed by the United States, or any other taxing authority, then, in any
such case, ComEd will pay as additional interest ("Additional Interest") such
additional amounts as shall be required so that the net amounts received and
retained by the Trust after paying any such taxes, duties, assessments or other
governmental charges will be equal to the amounts the Trust would have received
had no such taxes, duties, assessments or other governmental charges been
imposed.

INDENTURE EVENTS OF DEFAULT

          In case any Indenture Event of Default shall occur and be continuing,
the Property Trustee, as the holder of the Subordinated Notes, will have the
right to declare the principal of and the interest on the Subordinated Notes
(including any Additional Interest, if any) and any other amounts payable under
the Indenture to be forthwith due and payable and to enforce its other rights as
a creditor with respect to the Subordinated Notes.

          The Indenture provides that any one or more of the following described
events, which has occurred and is continuing, constitutes an "Event of Default"
with respect to the Subordinated Notes:

          (a) failure for 30 days to pay interest on the Subordinated Notes,
     including any Additional Interest in respect thereof, when due; provided,
     however, that a valid extension of the interest payment period by ComEd
     shall not constitute a default in the payment of interest for this purpose;
     or

          (b) failure to pay principal or premium, if any, on the Subordinated
     Notes when due whether at maturity, upon earlier redemption or otherwise;
     or

          (c) failure to observe or perform any other covenant (other than those
     specifically relating to another series of subordinated debt securities)
     contained in the Indenture for 90 days after written notice to ComEd from
     the Debt Trustee or the holders of at least 25% in principal amount of the
     outstanding Subordinated Notes; or

          (d) certain events of bankruptcy, insolvency or reorganization of
     ComEd; or

          (e) the voluntary or involuntary dissolution, winding-up or
     termination of the Trust, except in connection with the distribution of
     Subordinated Notes to the holders of Preferred Securities in liquidation of
     the Trust, the redemption of all outstanding Trust Securities of the Trust
     and certain mergers, consolidations or amalgamations permitted by the
     Declaration.

          The holders of a majority in aggregate outstanding principal amount of
the Subordinated Notes have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Debt Trustee.  The
Debt Trustee or the holders of not less than 25% in aggregate outstanding
principal amount of the Subordinated Notes may declare the principal due and
payable immediately on default, but the holders of a majority in aggregate
outstanding principal amount may annul such declaration and waive the default if
the default has been cured and a sum sufficient to pay all matured installments
of interest and principal due otherwise than by acceleration and any applicable
premium has been deposited with the Debt Trustee.

          The holders of a majority in aggregate outstanding principal amount of
the Subordinated Notes affected thereby may, on behalf of the holders of all the
Subordinated Notes, waive any past

                                     -31-
<PAGE>
 
default, except (i) a default in the payment of principal, premium, if any, or
interest (unless such default has been cured and a sum sufficient to pay all
matured installments of interest and principal due otherwise than by
acceleration and any applicable premium has been deposited with the Debt
Trustee) or (ii) a default in the covenant of ComEd not to declare or pay
dividends on, or make distributions with respect to, or redeem, purchase or
acquire any of its capital stock during an Extension Period.  An Indenture Event
of Default also constitutes a Declaration Event of Default.  The holders of
Preferred Securities in certain circumstances have the right to direct the
Property Trustee to exercise its rights as the holder of the Subordinated Notes.
See "Description of the Preferred Securities -- Declaration Events of Default"
and "-- Voting Rights."

BOOK-ENTRY AND SETTLEMENT

          If distributed to holders of Preferred Securities in connection with
the voluntary or involuntary dissolution, winding-up or liquidation of the Trust
as a result of the occurrence of a Special Event, the Subordinated Notes will be
issued in the form of one or more global certificates (each, a "Global
Security") registered in the name of the depositary or its nominee.  Except
under the limited circumstances described below, Subordinated Notes represented
by the Global Security will not be exchangeable for, and will not otherwise be
issuable as, Subordinated Notes in definitive form.  The Global Securities
described above may not be transferred except by the depositary to a nominee of
the depositary or by a nominee of the depositary to the depositary or another
nominee of the depositary or to a successor depositary or its nominee.

          The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form.  Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.

          Except as provided below, owners of beneficial interests in such a
Global Security will not be entitled to receive physical delivery of
Subordinated Notes in definitive form and will not be considered the holders (as
defined in the Indenture) thereof for any purpose under the Indenture, and no
Global Security representing Subordinated Notes shall be exchangeable, except
for another Global Security of like denomination and tenor to be registered in
the name of the depositary or its nominee or to a successor depositary or its
nominee.  Accordingly, each beneficial owner must rely on the procedures of the
depositary and, if such person is not a Participant, on the procedures of the
Participant through which such person owns its interest, to exercise any rights
of a Holder under the Indenture.

          If Subordinated Notes are distributed to holders of Preferred
Securities in liquidation of such holders' interests in the Trust, DTC will act
as securities depositary for the Subordinated Notes.  For a description of DTC
and the specific terms of the depository arrangements, see "Description of the
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company."  The description therein of DTC's book-entry system and DTC's
practices as they relate to purchases, transfers, notices and payments with
respect to the Preferred Securities apply in all material respects to any debt
obligations represented by one or more Global Securities held by DTC.  ComEd may
appoint a successor to DTC or any successor depositary in the event DTC or such
successor depositary is unable or unwilling to continue as depositary.

          None of ComEd, the Trust, the Debt Trustee, any paying agent and any
other agent of ComEd or the Debt Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Security for such Subordinated
Notes or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

                                     -32-
<PAGE>
 
          A Global Security shall be exchangeable for Subordinated Notes
registered in the names of persons other than the depositary or its nominee only
if (i) the depositary notifies ComEd that it is unwilling or unable to continue
as a depositary for such Global Security and no successor depositary shall have
been appointed, or if at any time the depositary ceases to be registered or in
good standing under the Exchange Act (or other applicable statute or regulation)
at a time when the depositary is required to be so registered to act as such
depositary and no successor depositary shall have been appointed by ComEd within
90 days after ComEd receives such notice or becomes aware of such condition,
(ii) ComEd in its sole discretion determines that such Global Security shall be
so exchangeable or (iii) there shall have occurred an Event of Default with
respect to such Subordinated Notes. Any Global Security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for Subordinated Notes
registered in such names as the depositary shall direct. It is expected that
such instructions will be based upon directions received by the depositary from
its Participants with respect to ownership of beneficial interests in such
Global Security.

          In the event the Subordinated Notes are not represented by one or more
Global Securities, certificates evidencing Subordinated Notes may be presented
for registration of transfer (with the form of transfer endorsed thereon duly
executed) or exchange, at the office of the Note Registrar or at the office of
any transfer agent designated by ComEd for such purpose with respect to the
Subordinated Notes, without service charge and upon payment of any taxes and
other governmental charges as described in the Indenture.  Such transfer or
exchange will be effected upon the Note Registrar or such transfer agent, as the
case may be, being satisfied with the documents of title and identity of the
person making the request.  ComEd has appointed the Debt Trustee as Note
Registrar with respect to the Subordinated Notes.  ComEd may at any time rescind
the designation of any such transfer agent or approve a change in the location
through which any such transfer agent acts, except that ComEd will be required
to maintain a transfer agent at the place of payment.  ComEd may at any time
designate additional transfer agents with respect to the Subordinated Notes.

          In the event of any redemption in part, ComEd shall not be required to
(i) issue, exchange or register the transfer of Subordinated Notes during a
period beginning at the opening of business 15 days before the day of the
mailing of a notice of redemption of less than all of the Subordinated Notes and
ending at the close of business on the date of such mailing and (ii) register
the transfer of or exchange any Subordinated Notes so selected for redemption,
in whole or in part, except the unredeemed portion of any Subordinated Notes
being redeemed in part.

PAYMENT AND PAYING AGENTS

          Payment of principal of and premium (if any) on the Subordinated Notes
will be made only against surrender to the Paying Agent of the Subordinated
Notes.  Principal of and any premium and interest, if any, on Subordinated Notes
will be payable, subject to any applicable laws and regulations, at the office
of such Paying Agent or Paying Agents as ComEd may designate from time to time,
except that at the option of ComEd payment of any interest may be made by check
mailed to the address of the person entitled thereto as such address shall
appear in the Note Register with respect to the Subordinated Notes.  Payment of
interest on the Subordinated Notes on any Interest Payment Date will be made to
the person in whose name the Subordinated Note (or predecessor security) is
registered at the close of business on the Regular Record Date for such interest
payment.

          The Debt Trustee will act as Paying Agent with respect to the
Subordinated Notes.  ComEd may at any time designate additional Paying Agents or
rescind the designation of any Paying Agents or approve a change in the office
through which any Paying Agent acts, except that ComEd will be required to
maintain a Paying Agent at the place of payment.

          All moneys paid by ComEd to a Paying Agent for the payment of the
principal of or premium or interest, if any, on the Subordinated Notes which
remain unclaimed at the end of two years after such principal, premium, if any,
or interest shall have become due and payable will be repaid to

ComEd and the holder of such Subordinated Notes will thereafter look only to
ComEd for payment thereof.

MODIFICATION OF THE INDENTURE

          The Indenture contains provisions permitting ComEd and the Debt
Trustee, with the consent of the holders of not less than a majority in
principal amount of the Subordinated Notes, to modify the Indenture or any
supplemental indenture affecting that series or the rights of the holders of the
Subordinated Notes; provided that no such modification may, without the consent
of the holder of each outstanding Subordinated Note affected thereby, (i) extend
the fixed maturity of the Subordinated Notes, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any premium payable upon the redemption thereof, without the consent
of the holder of the Subordinated Notes so affected or (ii) reduce the
percentage of Subordinated Notes, the holders of which are required to consent
to any such supplemental indenture, without the consent of the holders of each
Subordinated Note then outstanding and affected thereby.

          In addition, ComEd and the Debt Trustee may execute, without the
consent of holders of the Subordinated Notes, any supplemental indenture for
certain other usual purposes including the creation of any new series of
subordinated debt securities.

CONSOLIDATION, MERGER AND SALE

          The Indenture does not contain any covenant which restricts the
Trust's or ComEd's ability to merge or consolidate with or into any other
corporation, sell or convey all or substantially all of its assets to any
person, firm or corporation or otherwise engage in restructuring transactions.

DEFEASANCE AND DISCHARGE

          Under the terms of the Indenture, ComEd will be discharged from any
and all obligations in respect of the Subordinated Notes (except in each case
for certain obligations with respect to denominations and provisions for payment
of the Subordinated Notes and obligations to register the transfer or exchange
of Subordinated Notes, replace stolen, lost or mutilated Subordinated Notes,
maintain paying agencies and hold moneys for payment in trust) if ComEd (i)
deposits with the Debt Trustee, in trust, moneys or governmental obligations, in
an amount sufficient to pay all the principal of, and interest on, the
Subordinated Notes on the dates such payments are due in accordance with the
terms of such Subordinated Notes and (ii) delivers to the Debt Trustee an
opinion of counsel to the effect that, based upon ComEd's receipt from, or the
publication by, the Internal Revenue Service of a ruling or a change in law, the
holders of the Subordinated Notes will not recognize income, gain or loss for
United States federal income tax purposes as a result of the deposit, defeasance
and discharge and will be subject to United States federal income tax on the
same amount and in the same manner and at the same times as would have been the
case if such deposit, defeasance or discharge had not occurred.

GOVERNING LAW

          The Indenture and the Subordinated Notes will be governed by, and
construed in accordance with, the internal laws of the State of New York.

INFORMATION CONCERNING THE DEBT TRUSTEE

          The Debt Trustee, prior to default, undertakes to perform only such
duties as are specifically set forth in the Indenture and, after default, shall
exercise the same degree of care as a prudent individual would exercise in the
conduct of his or her own affairs.  Subject to such provision,

                                     -34-
<PAGE>
 
the Debt Trustee is under no obligation to exercise any of the powers vested in
it by the Indenture at the request of any holder of Subordinated Notes, unless
offered reasonable indemnity by such holder against the costs, expenses and
liabilities which might be incurred thereby; but the foregoing shall not relieve
the Debt Trustee, upon the occurrence of an Indenture Event of Default, from
exercising the rights and powers vested in it by the Indenture. The Debt Trustee
is not required to expand or risk its own funds or otherwise incur personal
financial liability in the performance of its duties if the Debt Trustee
reasonably believes that repayment or adequate indemnity is not reasonably
assured to it.

MISCELLANEOUS

          ComEd will have the right at all times to assign any of its rights or
obligations under the Indenture to a direct or indirect wholly-owned subsidiary
of ComEd; provided that, in the event of any such assignment, ComEd will remain
liable for all of their obligations.  Subject to the foregoing, the Indenture
will be binding upon and inure to the benefit of the parties thereto and their
respective successors and assigns.  The Indenture provides that it may not
otherwise be assigned by the parties thereto.

          The Indenture will provide that ComEd will pay all fees and expenses
related to (i) the offering of the Trust Securities and the Subordinated Notes,
(ii) the organization, maintenance and dissolution of the Trust, (iii) the
retention of the ComEd Trustees and (iv) the enforcement by the Property Trustee
of the rights of holders of Preferred Securities.

               EFFECT OF OBLIGATIONS UNDER THE SUBORDINATED NOTES
                     AND THE PREFERRED SECURITIES GUARANTEE

          As set forth in the Declaration, the sole purposes of the Trust are to
(i) issue Trust Securities, (ii) invest the proceeds thereof in the Subordinated
Notes and (iii) engage in only those other activities necessary or incidental
thereto.

          As long as payments of interest and other payments are made when due
on the Subordinated Notes, such payments will be sufficient to cover
distributions and payments due on the Trust Securities primarily because (i) the
aggregate principal amount of Subordinated Notes will be equal to the sum of the
aggregate stated liquidation amount of the Trust Securities; (ii) the interest
rate and interest and other payment dates on the Subordinated Notes will match
the distribution rate and distribution and other payment dates for the Preferred
Securities; (iii) ComEd shall pay for all costs and expenses of the Trust; and
(iv) the Declaration provides that the ComEd Trustees shall not cause or permit
the Trust to, among other things, engage in any activity that is not consistent
with the purposes of the Trust.

          Payments of distributions (to the extent funds therefor are available)
and other payments due on the Preferred Securities (to the extent funds therefor
are available) are guaranteed by ComEd as and to the extent set forth under
"Description of the Preferred Securities Guarantee".  If ComEd does not make
interest payments on the Subordinated Notes purchased by the Trust, it is
expected that the Trust will not have sufficient funds to pay distributions on
the Preferred Securities.  The Preferred Securities Guarantee is a full and
unconditional guarantee from the time of its issuance, but does not apply to any
payment of distributions unless and until the Trust has sufficient funds for the
payment of such distributions.

          If ComEd fails to make interest or other payments on the Subordinated
Notes when due (taking into account any Extension Period), the Declaration
provides a mechanism whereby the holders of the Preferred Securities, using the
procedures described in "Description of the Preferred Securities -- Voting
Rights," may direct the Property Trustee to enforce its rights under the
Subordinated Notes, including proceeding directly against ComEd to enforce the
Subordinated Notes.  If the Property

                                     -35-
<PAGE>
 
Trustee fails to enforce its rights under the Subordinated Notes, a holder of
Preferred Securities may, after a period of 30 days has elapsed from such
holder's written request to the Property Trustee to enforce such rights,
institute a legal proceeding directly against ComEd to enforce the Property
Trustee's rights under the Subordinated Notes without first instituting any
legal proceeding against the Property Trustee or any other person or entity,
including the Trust.

          If ComEd fails to make payments under the Preferred Securities
Guarantee, the Preferred Securities Guarantee provides a mechanism whereby the
holders of the Preferred Securities may direct the Preferred Guarantee Trustee
to enforce its rights thereunder.  If the Preferred Guarantee Trustee fails to
enforce the Preferred Securities Guarantee, any holder of Preferred Securities
may institute a legal proceeding directly against ComEd to enforce the Preferred
Guarantee Trustee's rights under the Preferred Securities Guarantee, without
first instituting a legal proceeding against the Trust, the Preferred Guarantee
Trustee or any other person or entity.

          ComEd and the Trust believe that the above mechanisms and obligations,
taken together, are substantially equivalent to a full and unconditional
guarantee by ComEd of payments due on the Preferred Securities.  See
"Description of the Preferred Securities Guarantees -- General."

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

          The following is a summary of certain of the principal United States
federal income tax consequences of the purchase, ownership and disposition of
the Preferred Securities to a holder that is a citizen or resident of the United
States, a corporation, partnership or other entity created or organized under
the laws of the United States or any state thereof or the District of Columbia
or an estate or trust the income of which is subject to United States federal
income taxation regardless of source (a "Holder").  This summary does not
address the United States federal income tax consequences to persons other than
Holders.

          This summary is based on the United States federal income tax laws,
regulations and rulings and decisions now in effect, all of which are subject to
change, possibly on a retroactive basis.  This summary does not address the tax
consequences applicable to investors that may be subject to special tax rules
such as banks, thrifts, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or currencies, tax-exempt
investors or persons that will hold the Preferred 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.  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 a Holder.

CLASSIFICATION OF COMED FINANCING

          Sidley & Austin, counsel to ComEd and special counsel to the Trust, is
of the opinion that, under current law and assuming full compliance with the
terms of the Indenture and the Declaration (and certain other documents), the
Trust will be classified as a "grantor trust" for federal income tax purposes
and will not be classified as an association taxable as a corporation or a
partnership.  Each Holder will be treated as owning an undivided beneficial
interest in the Subordinated Notes.  Accordingly, each Holder will be required
to include in its gross income the original issue discount ("OID") accrued with
respect to its allocable share of Subordinated Notes.  Investors should be aware
that the opinion of Sidley & Austin does not address any other issue and is not
binding on the Internal Revenue Service (the "Service") or the courts.

                                     -36-
<PAGE>
 
ORIGINAL ISSUE DISCOUNT, PREMIUM AND MARKET DISCOUNT

          Because of the option that ComEd has, under the terms of the
Subordinated Notes, to defer payments of interest by extending interest payment
periods for up to 20 quarters, the Subordinated Notes will be treated as issued
with OID in an amount equal to all of the stated interest payments on the
Subordinated Notes.  Holders must include the OID attributable to the
Subordinated Notes in income on an economic accrual basis before the receipt of
cash attributable to the interest, regardless of their method of tax accounting.
The amount of OID that accrues in any month will approximately equal the amount
of the interest that accrues in that month at the stated interest rate.  In the
event that the interest payment period is extended, Holders will continue to
accrue OID approximately equal to the amount of the interest payment due at the
end of the extended interest payment period on an economic accrual basis over
the length of the extended interest period.  Corporate Holders will not be
entitled to a dividends-received deduction with respect to any income earned
with respect to the Preferred Securities.

          To the extent a Holder acquires its Preferred Securities at a price
that is greater or less than the adjusted issue price of such Holder's share of
Subordinated Notes (which generally should approximate par plus accrued but
unpaid interest), the Holder will be deemed to have acquired its interest in the
Preferred Securities with acquisition premium or with market discount, as the
case may be.  A Holder acquiring Preferred Securities at a premium will be
permitted to reduce the amount of OID required to be included in income to
reflect the acquisition premium.  A Holder acquiring Preferred Securities at a
market discount will also include the amount of such discount in income in
accordance with the market discount rules described below.

          A Holder acquiring Preferred Securities at a market discount generally
will be required to recognize ordinary income to the extent of accrued market
discount upon the retirement of the underlying Subordinated Notes or, to the
extent of any gain, upon the disposition of the Preferred Securities.  Such
market discount would accrue ratably, or, at the election of the Holder, under a
constant yield method over the remaining term of the Subordinated Notes.  A
Holder will also be required to defer the deduction of a portion of the interest
paid or accrued on indebtedness incurred to purchase or carry Preferred
Securities acquired with market discount.  In lieu of the foregoing, a Holder
may elect to include market discount in income currently as it accrues on all
market discount instruments acquired by such Holder in the taxable year of the
election or thereafter, in which the interest deferral rule will not apply.  A
Holder may elect, in lieu of applying the market discount or premium rules
described above, to account for all income under the Preferred Securities as if
it were OID.

RECEIPT OF SUBORDINATED NOTES UPON LIQUIDATION OF THE TRUST

          Under certain circumstances, as described under the caption
"Description of the Preferred Securities -- Special Event Redemption or
Distribution," Subordinated Notes may be distributed to Holders in exchange for
the Preferred Securities and in liquidation of the Trust.  Such a distribution
would be treated as a non-taxable event to each Holder and each Holder would
receive an aggregate tax basis in the Subordinated Notes equal to such Holder's
aggregate tax basis in the Preferred Securities.  A Holder's holding period in
the Subordinated Notes so received in liquidation of the Trust would include the
period for which the Preferred Securities were held by such Holder.

SALE OF PREFERRED SECURITIES

          A Holder that sells Preferred Securities will recognize gain or loss
equal to the difference between its adjusted tax basis in the Preferred
Securities and the amount realized on the sale.  A Holder's adjusted tax basis
in the Preferred Securities generally will be its initial purchase price
increased by original issue discount previously includible in such Holder's
gross income to the date of

                                     -37-
<PAGE>
 
disposition (and the accrual of market discount, if any) and decreased by
payments received on the Preferred Securities.  Subject to the market discount
rules described above, any such gain or loss generally will be capital gain or
loss.

          The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Subordinated Notes.  A Holder disposing of its Preferred Securities between
record dates for payments of distributions thereon will be required to include
accrued but unpaid interest through the date of disposition in income as
ordinary income (i.e. OID), and to add such amount to its adjusted tax basis in
its Preferred Securities.  To the extent the selling price is less than the
Holder's adjusted tax basis (which will include, in the form of OID, 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.

FOREIGN INVESTORS

          Subject to the discussion of backup withholding below, interest
(including OID) with respect to the Preferred Securities paid to a nonresident
alien individual, foreign corporation, foreign partnership or foreign estate or
trust will be exempt from U.S. withholding tax, provided that the holder
complies with applicable certification requirements (and does not actually or
constructively own ten percent or more of the voting stock of ComEd and is not a
controlled foreign corporation related to ComEd or its affiliates).

INFORMATION REPORTING TO HOLDERS

          Subject to the qualifications discussed below, income on the Preferred
Securities will be reported to Holders on Form 1099, which forms should be
mailed to Holders of Preferred Securities by January 31 following each calendar
year.

          The Trust will be obligated to report annually to Cede & Co., as
Holder of record of the Preferred Securities, the OID with respect to the
Preferred Securities that accrued during that year.  The Trust currently intends
to report such information on Form 1099 prior to January 31 following each
calendar year even though the Trust is not legally required to report to record
Holders until April 15 following each calendar year.  The Underwriters have
indicated to the Trust that, to the extent that they hold Preferred Securities
as nominees for beneficial Holders, they currently expect to report to such
beneficial Holders on Forms 1099 by January 31 following each calendar year.
Under current law, Holders of Preferred Securities who hold as nominees for
beneficial Holders will not have any obligation to report information regarding
the beneficial Holders to the Trust.  The Trust, moreover, will not have any
obligation to report to beneficial Holders who are not also record holders.
Thus, beneficial Holders of Preferred Securities who hold their Preferred
Securities through the Underwriters will receive Forms 1099 reflecting the
income on their Preferred Securities from such nominee Holders rather than the
Trust.

BACKUP WITHHOLDING

          Payments made on, and proceeds from the sale of, the Preferred
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 federal income tax, provided that
required information is provided to the Service.

          THE 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 RESPECT TO

                                     -38-

THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE
PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN
AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX
LAWS.


                                  UNDERWRITING

          Subject to the terms and conditions set forth in an underwriting
agreement (the "Underwriting Agreement"), the Trust has agreed to sell to each
of the underwriters named below (the "Underwriters"), and each of the
Underwriters, for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated is
acting as representative (the "Representative"), has severally agreed to
purchase the number of Preferred Securities set forth opposite its name below.
In the Underwriting Agreement, the several Underwriters have agreed, subject to
the terms and conditions set forth therein, to purchase all of the Preferred
Securities offered hereby if any of the Preferred Securities are purchased.  In
the event of default by an Underwriter, the Underwriting Agreement provides
that, in certain circumstances, the purchase commitments of the nondefaulting
Underwriters may be increased or the Underwriting Agreement may be terminated.

                                    NUMBER OF PREFERRED
UNDERWRITER                         SECURITIES
- -----------                         -------------------



Total............................    
                                      _______


          The Underwriters propose to offer the Preferred Securities in part
directly to the public at the initial public offering price, as set forth on the
cover page of this Prospectus, and in part to certain securities dealers at such
price less a concession of $ ____ per Preferred Security.  The Underwriters may
allow, and such dealers may reallow, a concession not in excess of $ ____  per
Preferred Security to certain brokers and dealers.  After the Preferred
Securities are released for sale to the public, the offering price and other
selling terms may from time to time be varied by the Representative.

          In view of the fact that the proceeds of the sale of the Preferred
Securities will be used to purchase the Subordinated Notes of ComEd, the
Underwriting Agreement provides that ComEd will agree to pay as compensation
("Underwriters' Compensation") to the Underwriters for the Underwriters'
arranging the investment therein of such proceeds, an amount in New York
Clearing House (next day) funds of $ ____  per Preferred Security (or $ ____ in
the aggregate) for the accounts of the several Underwriters, provided that such
compensation for sales of 10,000 or more Preferred Securities to any single
purchaser will be $ ____ per Preferred Security.  Therefore, to the extent of
such sales, the actual amount of Underwriters' Compensation will be less than
the aggregate amount specified in the preceding sentence.

          During a period of 30 days from the date of the pricing of the
Preferred Securities, neither the Trust nor ComEd will, without the prior
written consent of the Representative, directly or indirectly, sell, offer to
sell, contract to sell, grant any option for the sale of, or otherwise dispose
of, any Preferred Securities, any security convertible into or exchangeable into
or exercisable for Preferred Securities or the Subordinated Notes or any debt
securities substantially similar to the Subordinated

                                     -39-
<PAGE>
 
Notes or any equity securities substantially similar to the Preferred Securities
(except for any series of subordinated debt securities and the Preferred
Securities offered hereby).

          An application will be filed with the New York Stock Exchange for the
listing of the Preferred Securities, subject to official notice of issuance.  If
approved for listing, trading of the Preferred Securities on the New York Stock
Exchange is expected to commence within a 30 day period after the initial
delivery of the Preferred Securities.  The Representative has advised the Trust
that the Underwriters intend to make a market in the Preferred Securities prior
to the commencement of trading on the New York Stock Exchange.  The Underwriters
will have no obligation to make a market in the Preferred Securities, however,
and may cease market making activities, if commenced, at any time.

          Prior to this offering, there has been no public market for the
Preferred Securities.  In order to meet one of the requirements for listing the
Preferred Securities on the New York Stock Exchange, the Underwriters will
undertake to sell lots of 100 or more Preferred Securities to a minimum of 400
beneficial holders.

          ComEd and the Trust have agreed to indemnify the Underwriters against,
or to contribute to payments that the Underwriters may be required to make in
respect of, certain liabilities, including liabilities under the Securities Act.

          Certain of the Underwriters engage in transactions with, and, from
time to time, have performed services for, ComEd in the ordinary course of
business.

          It is expected that delivery of the Preferred Securities will be made
against payment therefor on or about the date specified in the last paragraph of
the cover page hereof, which is the fifth business day following the date
hereof.  Under Rule 15c6-1 recently adopted by the Commission under the Exchange
Act, trades in the secondary market generally are required to settle in three
business days, unless the parties to any such trade expressly agree otherwise.
Accordingly, purchasers who wish to trade the Preferred Securities on the date
hereof or the next succeeding business day will be required, by virtue of the
fact that the Preferred Securities initially will settle in T+5, to specify
alternate arrangements to prevent a failed settlement.

                                 LEGAL MATTERS

          Certain matters of Delaware law relating to the validity of the
Preferred Securities will be passed upon on behalf of the Trust by Richards,
Layton & Finger, special Delaware counsel to the Trust.  The validity of the
Subordinated Notes, the Preferred Securities Guarantee and certain matters
relating thereto will be passed upon on behalf of ComEd by Sidley & Austin,
Chicago, Illinois.  Certain legal matters will be passed upon on behalf of the
Underwriters by their counsel.  Certain United States federal income taxation
matters will be passed upon for ComEd and the Trust by Sidley & Austin.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Certain provisions of the Illinois Business Corporation Act of 1983
(the "BCA") provide that ComEd may, and in some circumstances must, indemnify
the directors and officers of ComEd and of each subsidiary company against
liabilities and expenses incurred by any such person by reason of the fact that
such person was serving in such capacity, subject to certain limitations and
conditions set forth in the statute.  ComEd's By-laws provide that ComEd will
indemnify its directors and officers, and any person serving as a director or
officer of another business entity at ComEd's request, to the extent permitted
by the statute.  In addition, ComEd's Restated Articles of Incorporation
provide, as permitted by the BCA, that directors shall not be personally liable
for monetary damages for breach of fiduciary duty as a director, except (i) for
breaches of their duty of loyalty to ComEd or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 8.65 of the BCA, and (iv) for transactions
from which a director derived an improper personal benefit.

          ComEd has purchased liability insurance policies which indemnify
ComEd's directors and officers, the directors and officers of subsidiaries of
ComEd, the trustees of the Service Annuity Funds, and officers of ComEd serving
as directors and officers on behalf of ComEd with certain other entities,
against loss arising from claims by reason of their legal liability for acts as
such directors, officers or trustees, subject to certain limitations and
conditions set forth in the policies.

          ComEd indemnifies assistant officers and certain other employees
against liabilities and expenses incurred by reason of acts performed in
connection with the operations of the various employee benefit systems of ComEd
and its subsidiaries.

          The Declaration of Trust provides that no Regular Trustee, affiliate
of any Regular Trustee, or any officers, directors, shareholders, members,
partners, employees, representatives, or agents of any Regular Trustee, or any
employee or agent of the Trust or its affiliates (each an "Indemnified Person")
shall be liable, responsible or accountable in damages or otherwise to the Trust
or any employee or agent of the trust or its affiliates for any loss, damage or
claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by the Declaration or by law, except that
an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's gross negligence or willful
misconduct with respect to such act or omission.  The Declaration of Trust also
provides that, to the fullest extent permitted by applicable law, ComEd shall
indemnify and hold harmless each Indemnified Person from and against any loss,
damage or claim incurred by such Indemnified Person by reason of any act or
omission performed or omitted by such Indemnified Person in good faith on behalf
of the Trust and in a manner such Indemnified Person 

                                      S-1
<PAGE>
 
reasonably believed to be within the scope of authority conferred on such
Indemnified Person by such Declaration, except that no Indemnified Person
shall be entitled to be indemnified in respect of any loss, damage or claim
incurred by such Indemnified Person by reason of gross negligence or willful
misconduct with respect to such act or omission. The Declaration of Trust
further provides that, to the fullest extent permitted by applicable law,
expenses (including legal fees) incurred by an Indemnified Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by ComEd prior to the final disposition of such claim, demand, action,
suit or proceeding upon receipt by ComEd of an undertaking by or on behalf of
the Indemnified Person to repay such amount if it shall be determined that the
Indemnified Person is not entitled to be indemnified for the underlying cause of
action as authorized by such Declaration.

ITEM 17.  UNDERTAKINGS.

THE UNDERSIGNED REGISTRANTS HEREBY UNDERTAKE:

     (1) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (2) That for purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrants pursuant to Rule 424(b)(1) or (4) under
the Securities Act of 1933 shall be deemed to be part of this registration
statement as of the time it was declared effective.

     (3) That for purposes of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrants pursuant to the provisions described in Item 15, or
otherwise, the registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by a
registrant of expenses incurred or paid by a director, officer or controlling
person of such 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, such 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.

          The undersigned Trust registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreement certificates
in such denominations and registered in such names as required by the
underwriters to permit prompt delivery to each purchaser.

     the Company, any significant subsidiary or the Trust; and the execution and
     delivery of this Agreement, the incurrence of the obligations herein set

          Any certificate signed by any officer or trustee of the Offerors and
delivered to you or to counsel for the Underwriters shall be deemed a joint and
several representation and warranty by the Offerors to each Underwriter as to
the matters covered thereby.

          3.   Purchase, Offering and Delivery -- Closing Time.  (a) Subject to
the terms and conditions herein set forth, the Trust agrees to sell to each
Underwriter, and each Underwriter agrees, severally and not jointly, to purchase
from the Trust at the purchase price set forth in the Pricing Agreement, the
number of Preferred Securities set forth opposite such Underwriter's name in
Schedule A hereto (except as otherwise provided in the Pricing Agreement), plus
any additional number of Preferred Securities that such Underwriter may become
obligated to purchase pursuant to the provisions of Section 9 hereof.  The
purchase price per security to be paid by the several Underwriters for the
Preferred Securities shall be an amount equal to the initial public offering
price.  The initial public offering price per Preferred Security shall be a
fixed price to be determined by Agreement between the Representative and the
Offerors.  The initial public offering price and the purchase price, when so
determined, shall be set forth in the Pricing Agreement.  In the event that such
prices have not been agreed upon and the Pricing Agreement has not been executed
and delivered by all parties thereto by the close of business on the fourteenth
business day following the date of this Agreement, this Agreement shall
terminate forthwith, without liability of any party to any other party, unless
otherwise agreed to by the Offerors and the Representative.  As compensation to
the Underwriters for their commitments hereunder and in view of the fact that
the proceeds of the sale of the Preferred Securities will be used to purchase
the Subordinated Debt Securities of the Company, the Company hereby agrees to
pay at Closing Time (as defined below) to the Representative, for the accounts
of the several Underwriters, a commission per Preferred Security determined by
agreement between the Representative and the Company for the Preferred
Securities to be delivered by the Trust hereunder at Closing.  The commission,
when so determined, shall be set forth in the Pricing Agreement.

          (b) Payment of the purchase price for, and delivery of certificates
for, the Preferred Securities shall be made at the office of Sidley & Austin, or
at such other

                                      -10-
<PAGE>
 
place as shall be agreed upon by the Representative and the Trust, at 10:00 A.M.
Chicago time on the fifth business day (unless postponed in accordance with the
provisions of Section 9) after execution of the Pricing Agreement, or such other
time not later than ten business days after such date as shall be agreed upon by
the Representative, the Trust and the Company (such time and date of payment and
delivery being herein called "Closing Time").  Payment shall be made to the
Trust by certified or official bank check or checks drawn in New York Clearing
House funds or similar next day funds payable to the order of the Trust to an
account designated by the Trust, against delivery to the Representative for the
respective accounts of the Underwriters of certificates for the Preferred
Securities to be purchased by them.  Certificates for the Preferred Securities
shall be in such denominations and registered in such names as the
Representative may request in writing at least two business days before the
Closing Time.  It is understood that each Underwriter has authorized the
Representative, for its account, to accept delivery of, receipt for, and make
payment of the purchase price for, the Preferred Securities which it has agreed
to purchase.  Merrill Lynch, individually and not as Representative of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Preferred Securities to be purchased by any Underwriter whose
check has not been received by the Closing Time, but such payment shall not
relieve such Underwriter from its obligations hereunder.

          The certificate(s) for the Preferred Securities will be made available
for examination and packaging by the Representative not later than 10:00 A.M. on
the last business day prior to the Closing Time.

          At Closing Time, the Company will pay, or cause to be paid, the
commission payable at such time to the Underwriters under this Section 3 by
certified or official bank check or checks payable to Merrill Lynch, Pierce,
Fenner & Smith Incorporated in New York Clearing House funds or other similar
next day funds.

          (c) In accordance with Rule 15c6-1(d) promulgated under the 1934 Act,
the Underwriters agree to the payment of funds and delivery of the Preferred
Securities in accordance with this Section 3 in lieu of that required by
paragraphs (a) and (c) of Rule 15c6-1 under the 1934 Act.

          4.   Agreements.  Each of the Offerors jointly and severally agrees
with the several Underwriters that:

          (a) The Offerors will give the Representative notice of their
     intention to file or prepare (i) any amendment to the Registration
     Statement (including any post-effective amendment), (ii) any amendment or
     supplement to the Prospectus (including any revised prospectus which the
     Offerors propose for use by the Underwriters in connection with the

                                      -11-
<PAGE>
 
     offering of the Preferred Securities which differs from the prospectus on
     file at the Commission at the time the Registration Statement becomes
     effective, whether or not such revised prospectus is required to be filed
     pursuant to Rule 424(b) of the 1933 Act Regulations), or (iii) any document
     that would as a result thereof be incorporated by reference in the
     Prospectus whether pursuant to the 1933 Act, the 1934 Act or otherwise,
     will furnish the Representative with copies of any such amendment,
     supplement or other document a reasonable amount of time prior to such
     proposed filing or use, as the case may be, and will not file any such
     amendment, supplement or other document or use any such prospectus to which
     the Representative or counsel for the Underwriters may reasonably object.
     Subject to the foregoing, the Offerors will promptly prepare a supplement
     to the Prospectus to reflect the terms of the Preferred Securities and the
     terms of the offering.  The Offerors will file the Prospectus as so
     supplemented pursuant to Rule 424(b) under the 1933 Act not later than the
     Commission's close of business on the second business day following the
     execution and delivery of this Agreement, or, if applicable, such earlier
     time as may be required by Rule 430A(a)(3) under the 1933 Act.

          (b) The Offerors will promptly advise the Representative (i) when the
     Registration Statement and any amendment thereto (including any post-
     effective amendment) shall have become effective, (ii) of the receipt of
     any comments from the Commission, (iii) of any request by the Commission
     for any amendment of the Registration Statement or amendment or supplement
     to the Prospectus or for any additional information, (iv) of the issuance
     by the Commission of any stop order suspending the effectiveness of the
     Registration Statement or the institution or threatening of any proceeding
     for that purpose and (v) of the receipt by the Company of any notification
     with respect to the suspension of the qualification of the Preferred
     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceeding for such purpose.  The Offerors will use their best efforts
     to prevent the issuance of any such stop order and, if issued, to obtain as
     soon as possible the withdrawal thereof.

          (c) If, at any time when a prospectus relating to the Preferred
     Securities is required to be delivered under the 1933 Act, any event occurs
     as a result of which the Prospectus as then amended or supplemented would
     include an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, or if it shall be
     necessary to amend or supplement the Registration Statement or the
     Prospectus to comply with the 1933 Act or the 1934 Act or the rules and

                                      -12-

     regulations of the Commission under such Acts, the Offerors promptly will
     prepare and file with the Commission, subject to paragraph (a) of this
     Section 4, an amendment or supplement which will correct such statement or
     omission or an amendment or supplement which will effect such compliance.

          (d) The Company will make generally available to the Trust's security
     holders and to the Representative a consolidated earnings statement (which
     need not be audited) of the Company for the 12-month period beginning on
     October 1, 1995, as soon as practicable after the end of such 12-month
     period, which will satisfy the provisions of Section 11(a) of the 1933 Act.

          (e) The Company will furnish without charge to (A) each of the
     Representative and counsel for the Underwriters a signed copy of the
     Registration Statement (but without exhibits incorporated by reference), as
     originally filed, all amendments thereto filed prior to Closing Time and
     all Incorporated Documents (including exhibits, other than exhibits
     incorporated by reference), (B) each other Underwriter a conformed copy of
     the Registration Statement (but without exhibits), as originally filed, all
     amendments thereto (but without exhibits) and all Incorporated Documents
     (but without exhibits other than the Company's latest Annual Report to
     shareholders) and (C) each Underwriter as many copies of the Prospectus
     and, so long as delivery of a prospectus or supplement thereto by an
     Underwriter or dealer may be required under the 1933 Act, any amendments
     thereof and supplements thereto (but without Incorporated Documents or
     exhibits), as soon as available and in such quantities as the
     Representative may reasonably request.

          (f) The Offerors will use their best efforts to arrange for the
     qualification of the Preferred Securities (and the Preferred Securities
     Guarantee) and the Subordinated Debt Securities for sale under the laws of
     such jurisdictions as the Representative may designate (provided, however,
     that none of the Offerors shall be obligated to qualify as a foreign
     corporation in, or to execute or file any general consent to service of
     process under the laws of, any jurisdiction), will maintain such
     qualifications in effect so long as required for the distribution of the
     Preferred Securities and will arrange for the determination of the legality
     of the Preferred Securities for purchase by institutional investors.

          (g) Whether or not the transactions contemplated hereunder are
     consummated or this Agreement is terminated, the Company will pay all

                                      -13-
<PAGE>
 
     costs and expenses incident to the performance of the obligations of the
     Offerors hereunder, including, but not limited to, (i) the printing and
     filing of the Registration Statement as originally filed and of each
     amendment thereto, (ii) all costs, taxes and expenses incident to the issue
     and delivery of the Preferred Securities to the Underwriters, (iii) the
     fees and disbursements of the Company's and the Trustee's counsel and
     accountants, (iv) the qualification of the Preferred Securities, the
     Preferred Securities Guarantee and the Subordinated Debt Securities under
     securities laws in accordance with the provisions of Section 4(f) hereof
     (including fees of counsel for the Underwriters not exceeding $2,000 and
     disbursements) incurred in connection with "Blue Sky" qualifications, (v)
     the printing and delivery to the Underwriters of copies of the Registration
     Statement as originally filed and of each amendment thereto, of each
     preliminary prospectus, and of the Prospectus and any amendments or
     supplements thereto (except the cost of amending or supplementing the
     Prospectus after ninety days following the Closing Time, which shall be at
     the expense of the Underwriters requesting same), (vi) the fee of the
     National Association of Securities Dealers, Inc., (vii) the fees and
     expenses of the Debt Trustee, including the fees and disbursements of
     counsel for the Debt Trustee in connection with the Indenture and the
     Subordinated Debt Securities, (viii) the fees and expenses of the Property
     Trustee and the Guarantee Trustee, including the fees and disbursements of
     counsel for the Property Trustee in connection with the Declaration and the
     Certificate of Trust, (ix) any fees payable in connection with the rating
     of the Preferred Securities and Subordinated Debt Securities, (x) the fees
     and expenses incurred in connection with the listing of the Preferred
     Securities (and the related Preferred Securities Guarantee) and, if
     applicable, the Subordinated Debt Securities on the New York Stock
     Exchange, (xi) the cost and charges of any transfer agent or registrar and
     (xii) the cost of qualifying the Preferred Securities with The Depository
     Trust Company.  Except as provided in this Section 4(g), Section 7 and
     Section 8 hereof, the Underwriters will pay all their own costs and
     expenses, including the fees of their counsel and any advertising expenses
     in connection with any offer they may make.

          (h) The Offerors will use best efforts to effect the listing of the
     Preferred Securities (including the Preferred Securities Guarantee with
     respect thereto) on the New York Stock Exchange; if the Preferred
     Securities are exchanged for Subordinated Debt Securities, the Company will
     use its best efforts to effect the listing of the Subordinated Debt
     Securities on the exchange on which the Preferred Securities were then
     listed.

          (i) During a period of 30 days from the date of the Pricing Agreement,
     neither the Trust nor the Company will offer, sell, contract to sell, grant
     any option for the sale of, or otherwise dispose of any Preferred
     Securities, any security convertible into or exchangeable into or
     exercisable for Preferred Securities or the Subordinated Debt Securities or
     any debt securities substantially similar to the Subordinated Debt
     Securities or equity securities substantially similar to the Preferred
     Securities (except for the Subordinated Debt Securities and the Preferred
     Securities issued pursuant to this Agreement), without the prior written
     consent of the Representative.

          5.   Conditions to the Obligations of the Underwriters.  The
obligations of the several Underwriters to purchase and pay for the Preferred
Securities shall be subject to the accuracy of the representations and
warranties on the part of the Offerors contained herein as of the date hereof
and Closing Time, to the accuracy of the statements of the Offerors made in any
certificates pursuant to the provisions hereof, to the performance by the
Offerors of their obligations hereunder and to the following additional
conditions:

          (a) The Registration Statement shall have become effective not later
     than 5:30 P.M. on the date hereof, or with the consent of the
     Representative, at a later time and date, not later, however, than 5:30
     P.M. on the first business day following the date hereof, or at such later
     time and date as may be approved by the Representative; and at Closing Time
     no stop order suspending the effectiveness of the Registration Statement

          (b) The Offerors shall have furnished to the Representative the
     opinion of Sidley & Austin, counsel for the Offerors, at Closing Time, to
     the effect that:

               (i) the Company is a validly organized and existing corporation
          in good standing under the laws of the State of Illinois;

               (ii) to our knowledge, the Trust is not a party to or otherwise
          bound by any agreement other than those described in the Prospectus;
          and the Trust is duly qualified and in good standing as a foreign
          company in any other jurisdiction in which such

                                      -15-
<PAGE>
 
          qualification is necessary, except to the extent that the failure to
          so qualify or be in good standing would not have a material adverse
          effect on the Trust;

               (iii)  the issue and sale of the Subordinated Debt Securities and
          the execution and delivery of the Guarantees by the Company in
          accordance with the terms of this Agreement, the Company's purchase of
          the Common Securities from the Trust and the Company's participation
          in the transactions otherwise contemplated by this Agreement have been
          duly and validly authorized by the necessary corporate action of the
          Company and by order duly entered by the Illinois Commerce Commission;

          need express no opinion) or of any federal commission or regulatory
          authority is required in respect of such issue and sale, such purchase
          or such participation, except (a) such as may be required under the
          1933 Act or the 1933 Act Regulations and (b) the qualification of the
          Declaration, the Preferred Securities Guarantee Agreement and the
          Indenture under the 1939 Act and 1939 Act Regulations;

          1933 Act and, to the knowledge of said counsel, no proceedings for a
          stop order are pending or threatened under Section 8(d) or 8(e) of the
          1933 Act;

               (v) the Registration Statement, as of its effective date, and the
          Prospectus, in the form first used by the Underwriters to confirm
          sales of the Preferred Securities (or as amended or supplemented, if
          applicable) (except, in each case, as to the financial statements,
          financial data, statistical data and supporting schedules contained or
          incorporated therein, with respect to which said counsel need express
          no opinion), comply as to form, in all material respects, with the
          1933 Act, the 1934 Act, the 1939 Act and the rules and regulations of
          the Commission under such Acts; and the Incorporated Documents (except
          as to the financial statements, financial data, statistical data and
          supporting schedules contained or incorporated therein, with respect
          to which said counsel need express no opinion), as of their respective
          dates of filing with the Commission, complied as to form, in all
          material respects, with the 1934 Act and the rules and regulations of
          the Commission thereunder;

                                      -16-
<PAGE>
 
          (vi) the execution and delivery of this Agreement and the Pricing
          Agreement by the Company have been duly authorized by the necessary
          corporate action; and this Agreement and the Pricing Agreement have
          been duly executed and delivered by the Company;

               (vii)  the Declaration has been duly authorized, executed and
          delivered by the Company, as sponsor, and has been duly executed and
          delivered by each of the Regular Trustees;

               (viii)  the statements in the Prospectus under the captions "Risk
          Factors," "Description of the Preferred Securities," "Description of
          the Preferred Securities Guarantee," "Description of the Subordinated
          Notes" and "Effect of Obligations Under the Subordinated Notes and the
          Preferred Securities Guarantee," insofar as they pertain to
          obligations of the Offerors and insofar as they purport to summarize
          certain provisions of the documents referred to under said captions,
          have been reviewed by them and constitute fair and accurate summaries
          of such provisions; and the Declaration, the Indenture and the
          Preferred Securities Guarantee Agreement filed with the Commission as
          part of the Registration Statement complied as to form in all material
          respects with the applicable requirements of the 1939 Act and the 1939
          Act Regulations;

               (ix) the Common Securities, the Preferred Securities, the
          Subordinated Debt Securities, each of the Guarantees, the Declaration,
          the Indenture and each of the Guarantee Agreements conform in all
          material respects to the descriptions thereof contained in the
          Prospectus and such descriptions fairly set forth the matters
          respecting the Common Securities, the Preferred Securities, the

          applicable provisions of the federal securities laws to be set forth
          in the Prospectus;

               (x) all of the issued and outstanding Common Securities of the
          Trust are owned of record by the Company free and clear, to our
          knowledge, of any security interest, mortgage, pledge, lien,
          encumbrance, claim or equitable right;

               (xi) the Declaration has been duly qualified under the 1939 Act;

<PAGE>
 
               (xii)  each of the Guarantee Agreements has been duly authorized,
          executed and delivered by the Company; the Preferred Securities
          Guarantee Agreement, assuming it is duly authorized, executed and
          delivered by the Guarantee Trustee, constitutes a valid and binding
          obligation of the Company, enforceable against the Company in
          accordance with its terms, except to the extent that enforcement
          thereof may be limited by Bankruptcy Exceptions; and the Preferred
          Securities Guarantee Agreement has been duly qualified under the 1939
          Act;

               (xiii)  the Indenture has been duly authorized, executed and
          delivered by the Company and, assuming due authorization, execution
          and delivery thereof by the Debt Trustee, is a valid and binding
          obligation of the Company, enforceable against the Company in
          accordance with its terms, except to the extent that enforcement
          thereof may be limited by the Bankruptcy Exceptions, and the Indenture
          has been duly qualified under the 1939 Act;

               (xiv)  the Subordinated Debt Securities are in the form
          contemplated by the Indenture, have been duly authorized, executed and
          delivered by the Company and, when authenticated by the Debt Trustee
          in the manner provided for in the Indenture and delivered against
          payment therefor as provided in this Agreement, will constitute valid
          and binding obligations of the Company, enforceable against the
          Company in accordance with their terms and entitled to the benefits
          provided by the Indenture, except to the extent that enforcement
          thereof may be limited by the Bankruptcy Exceptions; and, subject to
          like exception contained in the immediately preceding clause, the
          holder or holders of the Subordinated Debt Securities will be entitled
          to the payment of principal and interest as therein provided;

               (xv) the Subordinated Debt Securities are subordinate and junior

          Guarantee and the Common Securities Guarantee are subordinate and

                                      -18-
<PAGE>
 
               (xvii)  subject to certain immaterial exceptions, the Company has
          good and sufficient title to the principal plants and properties
          purported to be owned by it, subject to the lien of the Mortgage and
          to permitted liens as defined in said Mortgage;

               (xviii)  the franchise granted to the Company by the City Council
          of the City of Chicago under an ordinance effective January 1, 1992,
          is valid and subsisting and duly authorizes the Company to engage in
          the electric utility business conducted by it in such City; the
          several franchises of the Company outside the City of Chicago are
          valid and subsisting and authorize the Company to carry on its utility
          business in the several communities, capable of granting franchises,
          located in the territory served by the Company outside the City of
          Chicago;

               (xix)  to the knowledge of said counsel, (a) there are no
          material pending legal proceedings to which the Company or the Trust
          is a party or of which property of the Company or the Trust is the
          subject and which are required to be set forth in the Prospectus and
          (b) there are no such proceedings contemplated by governmental
          authorities, in each case other than those referred to in the
          Prospectus;

               (xx) none of the Offerors is an "investment company" or a company
          "controlled" by an "investment company" within the meaning of the 1940
          Act;

               (xxi)  the Company is a "holding company" within the meaning of
          the Public Utility Holding Company Act of 1935, as amended, but the
          Company and its subsidiaries are exempt from the provisions of such
          Act, except Section 9(a)(2) thereof, and such exemption is in full
          force and effect and, to our knowledge, there are no existing or
          overtly threatened proceedings contemplating the revocation or
          modification of such exemption;

               (xxii)  for federal income tax purposes (i) the Subordinated Debt
          Securities will constitute indebtedness of the Company and (ii) the
          interest on the Subordinated Debt Securities will be deductible by the
          Company on an economic accrual basis in accordance with section 163(e)
          of the Internal Revenue Code of 1986, as amended, and Treasury
          Regulation section 1.163-7;

                                      -19-
<PAGE>
 
               (xxiii)  under current law, 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 Preferred
          Securities generally will be considered the owner of an undivided
          interest in the Subordinated Debt Securities, and each holder will be
          required to include in its gross income any original issue discount
          accrued with respect to its allocable share of the Subordinated Debt
          Securities;

               (xxiv)  the discussion set forth in the Prospectus under the
          caption "Certain Federal Income Consequences" is a fair and accurate
          summary of the matters addressed therein, based upon current law and
          the assumption stated or referred to therein; and

               (xxv)  the statements, if any, contained or incorporated by
          reference in the Prospectus which are expressed therein to have been
          made on the authority of said counsel are, as to matters of law and
          legal conclusions, correct in all material respects; nothing has come
          to the attention of said counsel which causes them to believe that the
          Registration Statement or any amendment thereof (including the filing
          of any annual report on Form 10-K) at the time it became effective
          (except as to the financial statements, financial data, statistical
          data and supporting schedules contained or incorporated therein, with
          respect to which said counsel need express no opinion) contained an
          untrue statement of a material fact or omitted to state a material
          fact required to be stated therein or necessary to make the statements
          therein not misleading or that the Prospectus as amended or
          supplemented at the time it was filed pursuant to Rule 424 under the
          1933 Act contained, or as amended or supplemented as of the Closing
          Time (except as to the financial statements, financial data,
          statistical data and supporting schedules contained or incorporated
          therein, with respect to which said counsel need express no opinion)
          contains, an untrue statement of a material fact, or omitted or omits
          to state a material fact, necessary to make the statements therein, in
          the light of the circumstances under which they were made, not
          misleading; and to the knowledge of said counsel, there are no
          contracts or exhibits required to be filed with the Registration
          Statement which are not so filed.

               In giving its opinion, Sidley & Austin may rely as to certain
          matters of Delaware law upon the opinion of Richards, Layton &

                                      -20-

     the Offerors, in form and substance satisfactory to counsel for the

          good standing as a business trust under the Delaware Act, and all
          filings required under the laws of the State of Delaware with respect

          the power and authority to own property and conduct its business, all
          as described in the Registration Statement and the Prospectus;

               (iii)  the Declaration constitutes a valid and binding obligation
          of the Company and the Trustees and is enforceable against the Company
          and the Trustees in accordance with its terms, except to the extent
          that the enforcement thereof may be limited by the Bankruptcy
          Exceptions;

               (iv)  under the Delaware Act and the Declaration, the Trust has
          the power and authority to (i) execute and deliver, and to perform its
          obligations under, this Agreement and the Pricing Agreement and (ii)
          issue, and perform its obligations under, the Trust Securities;

               (v)  under the Delaware Act and the Declaration, the execution
          and delivery by the Trust of this Agreement, the Pricing Agreement and
          the performance by the Trust of its obligations hereunder and under
          the Pricing Agreement, have been duly authorized by all necessary
          action on the part of the Trust;

               (vi)  the certificates for the Preferred Securities are in due
          and proper form; the Preferred Securities have been duly authorized by
          the Declaration and are duly and validly issued and, subject to

          said counsel may note that the holders of the Preferred Securities may
          be obligated, pursuant to the Declaration, to (i) provide indemnity
          and/or security in connection with, and pay taxes or governmental

          Declaration and are duly and validly issued and fully paid and, except
          as otherwise provided in Section 10.1(b) of the Declaration,
          nonassessable undivided beneficial interests in the assets of the
          Trust;

               (viii)  under the Delaware Act and Declaration the issuance of
          the Trust Securities is not subject to preemptive or other similar
          rights; and

          the purchase by the Trust of the Subordinated Debt Securities, the
          execution, delivery and performance by the Trust of this Agreement and
          the Pricing Agreement, the consummation by the Trust of the
          transactions contemplated hereby and by the Pricing Agreement and
          compliance by the Trust with its obligations hereunder and thereunder
          will not violate (i) any of the provisions of the Certificate of Trust
          or the Declaration or (ii) any applicable Delaware law or
          administrative regulation.

               (ii) The Representative shall have received the favorable
     opinion, at Closing Time, of Richards, Layton & Finger, counsel of
     Wilmington Trust Company, as Property Trustee under the Declaration,
     Guarantee Trustee under the Preferred Securities Guarantee Agreement, in
     form and substance satisfactory to counsel for the Underwriters, to the
     effect that,

               (i) Wilmington Trust Company is duly organized and is validly
          existing in good standing as a banking corporation under the laws of
          the State of Delaware.

                                      -22-

          (ii)  the Property Trustee has full power, authority and legal right
          to execute, deliver and perform its obligations under the terms of the
          Declaration and the Preferred Securities Guarantee Agreement;

               (iii)  the execution, delivery and performance by the Property
          Trustee of the Declaration and the execution, delivery and performance
          by the Guarantee Trustee of the Preferred Securities Guarantee
          Agreement have been duly authorized by all necessary corporate action
          on the part of the Property Trustee and the Guarantee Trustee,
          respectively.  The Declaration and the Preferred Securities Guarantee
          Agreement have been duly executed and delivered by the Property
          Trustee and the Guarantee Trustee, respectively, and constitute the
          legal, valid and binding obligations of the Property Trustee and the
          Guarantee Trustee, respectively, enforceable against the Property
          Trustee and the Guarantee Trustee, respectively, in accordance with
          their terms, except as enforcement thereof may be limited by the
          Bankruptcy Exceptions;

               (iv)  the execution, delivery and performance of the Declaration
          and the Preferred Securities Guarantee Agreement by the Property
          Trustee and the Guarantee Trustee, respectively, does not conflict
          with or constitute a breach of the charter or by-laws of the Property
          Trustee and the Guarantee Trustee, respectively; and

               (v)  no consent, approval or authorization of, or registration
          with or notice to, any governmental authority or agency of the State
          of Delaware or the United States of America governing the banking or
          trust powers of Wilmington Trust Company is required for the
          execution, delivery or performance by the Property Trustee and the
          Guarantee Trustee of the Declaration and the Preferred Securities
          Guarantee Agreement.

          (iii)  The Representative shall have received the favorable opinion,
     at Closing Time, of [Skadden, Arps, Slate, Meagher & Flom
     ("SASM&F")/Winston & Strawn ("W&S")], counsel for the Underwriters, in form
     and substance satisfactory to the Underwriters with respect to the
     incorporation and legal existence of the Company; the legal existence of
     the Trust, the Preferred Securities, the Indenture, the Preferred
     Securities Guarantee Agreement, this Agreement, the Pricing Agreement, the
     Registration Statement, the Prospectus and other related matters as the
     Representative may require.

                                      -23-
<PAGE>
 
          In giving its opinion, SASM&F/W&S may rely as to certain matters of
     Delaware law upon the opinion of Richards, Layton & Finger, special counsel
     for the Offerors, which shall be delivered in accordance with Section
     5(c)(i) hereto.

          (d) At Closing Time, there shall not have been, since the respective
     dates as of which information is given in the Registration Statement and
     the Prospectus (in the form first used by the Underwriters to confirm sales
     of the Preferred Securities), any material adverse change in the condition,
     financial or otherwise, of the Trust or of the Company and its subsidiaries
     considered as one enterprise, or in the earnings, affairs or business
     prospects of the Company and its subsidiaries considered as one enterprise,
     in either case whether or not arising in the ordinary course of business,
     and you shall have received a certificate of the Chairman, the President, a
     Vice President or the Treasurer of the Company and a certificate of a
     Regular Trustee of the Trust, each at Closing Time, to the effect that (i)
     there has been no such material adverse change, (ii) the representations
     and warranties contained in this Agreement are true and correct with the
     same force and effect as though expressly made at and as of Closing Time,
     (iii) the Company and the Trust have complied with all agreements and
     satisfied all conditions on their part to be performed or satisfied at or
     prior to Closing Time and (iv) no stop order suspending the effectiveness
     of the Registration Statement has been issued and no proceedings for that
     purpose have been initiated or, to his knowledge, threatened by the
     Commission.

          (e) (i)  At the time of the execution of this Agreement, the
     Representative shall receive from Arthur Andersen LLP a letter (in form and
     substance satisfactory to them) dated such date to the effect that they are
     independent public accountants within the meaning of the 1933 Act and the
     applicable published rules and regulations thereunder and that the answer
     to Item 10 of the Registration Statement is correct insofar as it relates
     to them, and stating in effect that (i) in their opinion, the consolidated
     financial statements examined by them and contained in the Incorporated
     Documents comply as to form in all material respects with the applicable
     accounting requirements of the 1934 Act and the published rules and
     regulations thereunder; (ii) on the basis of a reading of the latest
     available unaudited interim consolidated financial statements of the
     Company, a reading of all recent minutes of meetings of the Board of
     Directors, Committees of the Board of Directors and shareholders of the
     Company and its subsidiaries and inquiries of officials of the Company
     responsible for financial and accounting matters, nothing came to their

                                      -24-
<PAGE>
 
     attention which caused them to believe that as of a specified date not more
     than three business days prior to the date of delivery of such letter there
     was any decrease in the capital stock or any increase in the long-term debt
     of the Company and subsidiaries consolidated, or any decrease in
     consolidated net assets, as compared with amounts shown in the consolidated
     balance sheet or consolidated statement of capitalization examined by them
     and included in the Company's Annual Report on Form 10-K, Quarterly Report
     on Form 10-Q or Current Report on Form 8-K, as the case may be, last filed
     under the 1934 Act and incorporated by reference in the Registration
     Statement or for the period from the first day of the month next following
     the date of said consolidated balance sheet and said consolidated statement
     of capitalization to a specified date not more than three business days
     prior to the date of delivery of such letter there were any decreases, as
     compared with the corresponding period in the preceding year, in
     consolidated electric operating revenues, net income, net income on common
     stock or earnings per common share, except in all instances for changes
     which the Prospectus discloses have occurred or may occur or which are
     described in such letter; (iii) they have read the dollar amounts of
     electric operating revenues by user classification in the table "Operating
     Statistics" in the Company's Annual Report on Form 10-K last filed under
     the 1934 Act and incorporated by reference in the Registration Statement,
     have performed specified procedures with respect thereto set forth in such
     letter and have found such dollar amounts to be in agreement with
     accounting records identified in such letter; (iv) if applicable, they have
     read the dollar amount of short-term notes payable and the ratio of
     earnings to fixed charges and the ratio of earnings to fixed charges and
     preferred and preference stock dividend requirements set forth in the
     Prospectus have performed specified procedures with respect thereto set
     forth in such letter and have found such dollar amount and ratios to be in
     agreement with accounting records identified in such letter; and (v) they
     have read any unaudited consolidated financial statement information and
     financial ratios set forth in the Prospectus and have performed specified
     procedures with respect thereto set forth in such letter, and nothing came
     to their attention which caused them to believe that such financial
     information does not agree with the latest available unaudited interim
     consolidated financial statements of the Company or was not determined on a
     basis substantially consistent with that of the corresponding amounts in
     the audited consolidated financial statements incorporated by reference in
     the Registration Statement.  If additional unaudited consolidated financial
     information is included in the Prospectus, appropriate statements with
     respect thereto shall also be set forth in such letter.

                                      -25-
<PAGE>
 
          (ii)  At Closing Time, the Representative shall have received from
     Arthur Andersen LLP a letter, dated as of Closing Time, to the effect that
     they reaffirm the statements made in the letter furnished pursuant to
     Section 5(e)(i), except that the specified date referred to shall be a date
     not more than five days prior to Closing Time.

          (f) Subsequent to the respective dates as of which information is
     given in the Registration Statement and the Prospectus, there shall not
     have been any change or decrease specified in the letters referred to in
     paragraph (e) of this Section 5 which makes it impractical or inadvisable
     in the judgment of the Representative to proceed with the public offering
     or delivery of the Preferred Securities as contemplated by the Prospectus.

          (g) At Closing Time, the Preferred Securities and the Subordinated
     Debt Securities shall be rated in one of the four highest rating categories
     for long-term debt ("Investment Grade") by any "nationally recognized
     statistical rating organization" as that term is defined by the Commission
     for purposes of Rule 436(g)(1) of Regulation C under the 1933 Act, and the
     Trust shall have delivered to the Representative a letter, at Closing Time,
     from such nationally recognized statistical rating organization, or other
     evidence satisfactory to the Representative, confirming that the Preferred
     Securities and the Subordinated Debt Securities have Investment Grade
     ratings; and subsequent to the date of this Agreement, no downgrading shall
     have occurred in the rating accorded the Company's debt securities or
     Cumulative Preference Stock by any  such nationally recognized statistical
     rating organization, and no such nationally recognized statistical rating
     organization shall have publicly announced that it has under surveillance
     or review, with possible negative implications, its ratings for such
     securities.

          (h) At Closing Time, the Preferred Securities shall have been approved
     for listing on the New York Stock Exchange upon notice of issuance.

          (i) Prior to Closing Time, the Offerors shall have furnished to the
     Representative such further information, certificates and documents as the
     Representative may reasonably request.

          If any of the conditions specified in this Section 5 shall not have
been fulfilled when and as provided in this Agreement, or if any of the opinions
or certificates mentioned above or elsewhere in this Agreement shall not be in
all material respects reasonably satisfactory in form and substance to the
Representative and counsel for the

                                      -26-
<PAGE>
 
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, Closing Time by the Representative.

          6.   Conditions of the Trust's Obligation.  The obligation of the
Trust to deliver the Preferred Securities upon payment therefor shall be subject
to the following conditions:

          At Closing Time, the order of the Illinois Commerce Commission
referred to in subparagraph (i) of Section 2 shall be in full force and effect
substantially in the form in which originally entered and no stop order
suspending the effectiveness of the Registration Statement shall be in effect
and no proceedings for that purpose shall then be pending before, or threatened
by, the Commission.

          In case any of the conditions specified above in this Section 6 shall
not have been fulfilled, this Agreement may be terminated by the Offerors by
delivering written notice of termination to the Representative.  Any such
termination shall be without liability of any party to any other party except to
the extent provided in Sections 4(g), 7 and 8 hereof.

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

          8.   Indemnification and Contribution.  (a) The Offerors agree jointly
and severally to indemnify and hold harmless each Underwriter and each person
who controls any Underwriter within the meaning of either the 1933 Act or the
1934 Act against any and all losses, claims, damages or liabilities, joint or
several, to which they or any of them may become subject under the 1933 Act, the
1934 Act or other federal or state statutory law or regulation, at common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement for
the registration of the Securities as originally filed or in any amendment
thereof, or in any preliminary prospectus or the Prospectus, or in any amendment
thereof or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or

                                      -27-
<PAGE>
 
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party for any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that (i) the Offerors will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Trust or the Company by or on behalf of any Underwriter through
the Representative specifically for use therein and (ii) such indemnity with
respect to any preliminary prospectus shall not inure to the benefit of any
Underwriter (or any person controlling such Underwriter) from whom the person
asserting any such loss, claim, damage or liability purchased any of the
Preferred Securities which are the subject thereof if such person did not
receive a copy of the Prospectus (or, if the Prospectus has been amended or
supplemented, the Prospectus as then amended or supplemented), excluding the
Incorporated Documents, at or prior to the confirmation of the sale of such
Preferred Securities to such person in any case where such delivery is required
by the 1933 Act and the untrue statement or omission of a material fact
contained in such preliminary prospectus was corrected in the Prospectus (or the
Prospectus as then amended or supplemented) and where the Offerors shall have
provided to the Representative in a timely manner sufficient copies of such
Prospectus.  This indemnity agreement will be in addition to any liability which
the Offerors may otherwise have.  The Company agrees to indemnify the Trust
against all loss, liability, claim, damage and expense whatsoever, as due from
the Trust under Section 8(a) hereunder.

          (b) Each Underwriter severally agrees to indemnify and hold harmless
the Offerors, their directors, trustees, their officers who sign the
Registration Statement and each person who controls the Offerors within the
meaning of either the 1933 Act or the 1934 Act, to the same extent as the
foregoing indemnity from the Offerors to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Offerors by or on behalf of such Underwriter through the Representative
specifically for use in the preparation of the documents referred to in the
foregoing indemnity.  This indemnity agreement will be in addition to any
liability which any Underwriter may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 8.  In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and,

                                      -28-
<PAGE>
 
to the extent that it may elect by written notice delivered to the indemnified
party promptly after receiving the aforesaid notice from such indemnified party,
to assume the defense thereof, with counsel satisfactory to such indemnified
party, unless the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party.  Upon receipt of notice from the indemnifying party to
such indemnified party of its election so to assume the defense of such action
and approval by the indemnified party of counsel, the indemnifying party will
not be liable to such indemnified party under this Section 8 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in connection with the assertion of legal defenses in
accordance with the next preceding sentence (it being understood, however, that
in no event shall the indemnifying party be liable for the fees and expenses of
more than one separate counsel (in addition to local counsel), approved by the
Representative in the case of subparagraph (a), representing all indemnified
parties in connection with any one action or separate but similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; and except that, if clause (i)
or (iii) is applicable, such liability shall be only in respect of the counsel
referred to in such clause (i) or (iii).

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in paragraphs (a) or (b)
of this Section 8 is due in accordance with its terms but is for any reason held
by a court to be unavailable on grounds of policy or otherwise, the Offerors and
the Underwriters shall contribute to the aggregate losses, expenses, claims,
damages and liabilities (including legal or other expenses reasonably incurred
in connection with investigating or defending same) to which the Offerors and
one or more of the Underwriters may be subject in such proportion so that the
Underwriters are responsible for that portion represented by the percentage that
the aggregate underwriting discounts appearing on the cover page of the
Prospectus bear to the aggregate public offering price for the Preferred
Securities appearing thereon and the Offerors are responsible for the balance;
provided, however, that (i) in no case shall any Underwriter (except as may be
provided in any Agreement Among Underwriters) be responsible for any amount in
excess of the aggregate underwriting discounts applicable to the Preferred
Securities purchased by such Underwriter hereunder and (ii) no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this

                                      -29-
<PAGE>
 
Section 8, each person who controls an Underwriter within the meaning of the
1933 Act or the 1934 Act shall have the same rights to contribution as such
Underwriter, and each person who controls the Offerors within the meaning of
either the 1933 Act or the 1934 Act, each officer of the Company who shall have
signed the Registration Statement, each director of the Company and each trustee
of the Trust shall have the same rights to contribution as the Offerors, subject
in each case to clauses (i) and (ii) of this paragraph (d).  Any party entitled
to contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this paragraph
(d), notify such party from whom contribution may be sought, but the omission to
so notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this paragraph (d).

          9.   Default by an Underwriter.  If any one or more of the
Underwriters shall fail to purchase and pay for the Preferred Securities agreed
to be purchased by such Underwriter or Underwriters hereunder and such failure
to purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the number
of Preferred Securities set forth opposite their names in Schedule A hereto bear
to the aggregate number of Preferred Securities set opposite the names of all
the remaining Underwriters) the Preferred Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase; provided, however,
that in the event that the aggregate number of Preferred Securities which the
defaulting Underwriter or Underwriters agreed but failed to purchase shall
exceed 10% of the aggregate number of the Preferred Securities set forth in
Schedule A hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Preferred
Securities and if such nondefaulting Underwriters do not purchase all the
Preferred Securities, this Agreement will terminate without liability to any
nondefaulting Underwriter or the Offerors, except as provided in Section 11
hereof.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Time shall be postponed for such period, not exceeding
seven days, as the Representative shall determine, in order that the required
changes in the Registration Statement and the Prospectus or in any other
documents or arrangements may be effected.  Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Offerors and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

          10.  Termination.  This Agreement shall be subject to termination in
the absolute discretion of the Representative, by notice given to the Offerors
prior to delivery of and payment for the Preferred Securities, if prior to such
time (i) there has been, since the date of this Agreement or since the
respective dates as of which information is given

                                      -30-
<PAGE>
 
in the Registration Statement and the Prospectus, any material adverse change in
the earnings, affairs, condition (financial or otherwise) or business prospects
of the Trust or the Company and its subsidiaries considered as one enterprise,
in either case whether or not arising in the ordinary course of business, (ii)
trading in securities of the Company or securities generally on the New York
Stock Exchange shall have been suspended or limited or minimum or maximum prices
for trading have been fixed, or maximum ranges for prices have been required by
said exchange or by order of the Commission or by order of any other
governmental authority, (iii) a banking moratorium shall have been declared
either by federal or New York State authorities or (iv) there shall have
occurred any outbreak or material escalation of hostilities or other calamity or
crisis, the effect of which on the financial markets of the United States is
such as to make it, in the judgment of the Representative, impracticable to
market the Preferred Securities or enforce contracts for the sale of the
Preferred Securities.  As used in this Section, the term "Prospectus" shall mean
the Prospectus in the form first used by the Underwriters to confirm sales of
the Preferred Securities.

          11.  Representations and Indemnities to Survive.  The respective
agreements, representations, warranties, indemnities and other statements of the
Offerors or their officers or Trustees and of the Underwriters set forth in or
made pursuant to this Agreement will remain in full force and effect, regardless
of any investigation made by or on behalf of any Underwriter or the Offerors or
any of the officers, directors, trustees or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Preferred
Securities.  The provisions of Sections 4(g), 7 and 8 hereof shall survive the
termination or cancellation of this Agreement.

          12.  Notices.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representative, will be mailed,
delivered or telegraphed and confirmed to it at Merrill Lynch World
Headquarters, North Tower, World Financial Center, New York, New York 10281-
1201, attention of John Thorndike, Managing Director, or, if sent to the Trust
or the Company, will be mailed, delivered or telegraphed and confirmed to it, at
the 37th floor, One First National Plaza, Box 767, Chicago, Illinois 60690-0767,
attention of the Treasurer.

          13.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and assigns and
the officers, directors, trustees and controlling persons referred to in Section
8 hereof, and no other person will have any right or obligation hereunder.  The
term "successors and assigns" as used in this Agreement shall not include any

          (i)  is not waivable under the Indenture, the Event of Default under
     this Declaration shall also not be waivable; or

     may only be waived by the vote of the Holders of at least the proportion in
     liquidation amount of the Preferred Securities that the relevant Super
     Majority represents to the aggregate principal amount of the Debentures
     outstanding.

Upon such waiver, any such default shall cease to exist, and any Event of
Default with respect to the Preferred Securities arising therefrom shall be
deemed to have been cured, for every purpose of this Declaration, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.  Any waiver by the Holders of the Preferred
Securities of an Event of Default with respect to the Preferred Securities shall
also be deemed to constitute a waiver by the Holders of the Common Securities of
any such Event of Default with respect to the Common Securities for all purposes
of this Declaration without any further act, vote, or consent of the Holders of
the Common Securities.

          (b)  The Holders of a Majority in liquidation amount of the Common
Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default in respect of the Common Securities

          (i)  is not waivable under the Indenture, except where the Holders of
     the Common Securities are deemed to have waived such Event of Default under
     this Declaration as provided below, the Event of Default under this
     Declaration is not waivable; or

          (ii)  which requires the consent or vote of all of the holders of the
     Debentures to be waived, the Event of Default

                                      -9-
<PAGE>
 
     under this Declaration may only be waived by the vote of all of the Holders
     of the Preferred Securities, provided that each Holder of Common Securities
     will be deemed to have waived any such Event of Default and all Events of
     Default with respect to the Common Securities and its consequences until
     all Events of Default with respect to the Preferred Securities have been
     cured, waived or otherwise eliminated and until such Events of Default have
     been so cured, waived or otherwise eliminated, the Property Trustee will be
     deemed to be acting solely on behalf of the Holders of the Preferred
     Securities and only the Holders of the Preferred Securities will have the
     right to direct the Property Trustee in accordance with the terms of the
     Securities.  Subject to the foregoing proviso, upon such waiver, any such
     default shall cease to exist, and any Event of Default with respect to the
     Common Securities arising therefrom shall be deemed to have been cured, for
     every purpose of this Declaration, but no such waiver shall extend to any
     subsequent or other default or Event of Default with respect to the Common
     Securities or impair any right consequent thereon.

          (c)  A waiver of an Event of Default under the Indenture by the
Property Trustee at the direction of the Holders of the Preferred Securities
constitutes a waiver of the corresponding Event of Default under this
Declaration.

shall, within 90 days after the occurrence of an Event of Default, transmit by
mail, first class postage prepaid, to the Holders of the Securities, notices of
all defaults with respect to the Securities known to the Property Trustee,
unless such defaults have been cured before the giving of such notice (the term
"defaults", for the purposes of this Section 2.7(a), is hereby defined as an
Event of Default as defined in the Indenture, not including any periods of grace
provided for therein and irrespective of the giving of any notice provided
therein); provided that, except for a default in the payment of the principal of
(or the premium, if any) or the interest on any of the Debentures or in the
payment of any sinking fund installment established for the Debentures, the
Property Trustee shall be protected in withholding such notice if and so long as
the board of directors, the executive committee, or a trust committee of
directors and/or Responsible Officers, of the Property Trustee in good faith
determine that the withholding of such notice is in the interests of the Holders
of the Securities.

          (b)  The Property Trustee shall not be deemed to have knowledge of any
default except:

          (i)  a default arising under Sections 6.01(a)(1) and 6.01(a)(2) of the
     Indenture; or

powers shall constitute the act of and serve to bind the Trust, and an action
taken by the Property Trustee in accordance with its powers shall constitute the
act of and serve to bind the Trust.  In dealing with a Trustee or the Trustees
acting on behalf of the Trust, no Person shall be required to inquire into the
authority of such Trustee or Trustees to bind the Trust.  Persons dealing with
the Trust are entitled to rely conclusively on the power and authority of a
Trustee or the Trustees as set forth in this Declaration.

          SECTION 3.5.  Title to Property of the Trust.  Except as provided in
Section 3.8 with respect to the Debentures and the Property Trustee Account or
as otherwise provided in this Declaration, legal title to all assets of the
Trust shall be vested in the Trust.  The Holders shall not have legal title of
any part

                                      -11-

     preservation and the continuation of the Trust's valid existence, rights,
     franchises and privileges as a statutory business trust under the laws of
     the State of Delaware and of each other jurisdiction in which such
     existence is necessary to protect the limited liability of the Holders of
     the Securities or to enable the Trust to effect the purposes for which the
     Trust was created;

          (p)  to take any action, not inconsistent with this Declaration or
     with applicable law, which the Regular Trustees determine in their

               (i)  causing the Trust not to be deemed to be an Investment

               (ii) causing the Trust not to be characterized for United States

               (iii) co-operating with the Debenture Issuer to ensure that the
          Debentures will be treated as indebtedness of the Debenture Issuer for

     Holders; and

          (q)  to take all action necessary to cause all applicable tax returns

          SECTION 3.7.  Prohibition of Actions by the Trust and the Trustees.
The Trust shall not, and the Trustees (including the Property Trustee) shall
not, and shall cause the Trust not to, engage in any activity other than as
required or authorized by this Declaration.  In particular, the Trust shall not,
and the Trustees (including the Property Trustee) shall not and shall cause the
Trust not to:

          (i) invest any proceeds received by the Trust from holding the
     Debentures but shall distribute all such proceeds to Holders of Securities
     pursuant to the terms of this Declaration and of the Securities;

          (ii) acquire any assets other than as expressly provided herein;

          (iii) possess Trust property for other than a Trust purpose;

          (vii) consent to the modification of the Debentures or any other asset
     of the Trust, unless the Trust shall have received an opinion of counsel to
     the effect that such modification will not cause more than an insubstantial
     risk that for United States federal income tax purposes the Trust will not
     be characterized as a grantor trust.

          SECTION 3.8.  Powers and Duties of the Property Trustee.  (a)  The
legal title to the Debentures shall be owned by and held of record in the name
of the Property Trustee in trust for the benefit of the Holders of the
Securities.  The right, title and interest of the Property Trustee to the
Debentures shall vest automatically in each Person who may hereafter be
appointed as Property Trustee as set forth in Section 5.6.  Such vesting and
cessation of title shall be effective whether or not conveyancing documents with
respect to the Debentures have been executed and delivered.

          (b)  The Property Trustee shall not transfer its right, title and
interest in the Debentures to the Regular Trustees or to the Delaware Trustee
(if the Property Trustee does not also act as Delaware Trustee).

          (c)  The Property Trustee shall:

          (i) establish and maintain a segregated non-interest bearing bank
     account (the "Property Trustee Account") in the name of and under the
     exclusive control of the Property Trustee on behalf of the Holders of the
     Securities and, upon the receipt of payments of funds made in respect of
     the Debentures held by the Property Trustee, deposit such funds into the
     Property Trustee Account and make payments to the Holders of the Preferred
     Securities and the Holders of the Common Securities from the Property
     Trustee Account in accordance with Section 6.1. Funds in the Property
     Trustee Account shall be held uninvested until disbursed in accordance with
     this Declaration.  The Property Trustee Account shall be an account which
     is maintained with a banking institution the rating on whose long-term
     unsecured indebtedness is at least equal to the rating assigned to the
     Preferred Securities by a "nationally recognized statistical rating
     organization", as that term is defined for purposes of Rule 436(g)(2) under
     the Securities Act;

          (ii) engage in such ministerial activities as shall be necessary or
     appropriate to effect the redemption of the Preferred Securities and the
     Common Securities to the extent the Debentures are redeemed or mature; and

          (iii) upon notice of distribution issued by the Regular Trustees in
     accordance with the terms of the Preferred Securities and the Common

     Securities upon the occurrence of certain special events (as may be defined
     in the terms of the Securities) arising from a change in law or a change in
     legal interpretation or other specified circumstances pursuant to the terms
     of the Securities.

          (d)  The Property Trustee shall take all actions and perform such
duties as may be specifically required of the Property Trustee pursuant to the
terms of the Securities.

Guarantee and the Common Securities Guarantee for the benefit of the Holders of
the Preferred Securities and the Common Securities, respectively.

          (f)  The Property Trustee shall take any Legal Action which arises out
of or in connection with an Event of Default or the Property Trustee's duties
and obligations under this Declaration (including the Securities Guarantees) or
the Trust Indenture Act.

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

                                      -16-
<PAGE>
 
          (i)  the Trust has been completely liquidated and the proceeds of the
     liquidation distributed to the Holders of Securities pursuant to the terms
     of the Securities; or

          (ii)  a Successor Property Trustee has been appointed and accepted
     that appointment in accordance with Section 5.6.

          (h)  The Property Trustee shall have the legal power to exercise all
of the rights, powers and privileges of a holder of Debentures under the
Indenture and, if an Event of Default occurs and is continuing, the Property
Trustee shall, for the benefit of the Holders of the Securities, enforce its
rights under the Indenture with respect to the Debentures and its rights under
the Securities Guarantees in accordance with the terms of the Securities
Guarantees, subject to the rights of the Holders pursuant to the terms of such
Securities and Securities Guarantees.

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

          (j)  Subject to this Section 3.8, the Property Trustee shall have none
of the powers or the authority of the Regular Trustees set forth in Section 3.6.

          The Property Trustee must exercise the powers set forth in this
Section 3.8 in a manner which is consistent with the purposes and functions of
the Trust set forth in Section 3.3 and the Property Trustee shall not take any
action which is inconsistent with the purposes and functions of the Trust set
out in Section 3.3.

          SECTION 3.9.  Certain Duties and Responsibilities of the Property
Trustee.  (a) The Property Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Declaration and in the terms of the Securities, and no implied covenants
shall be read into this Declaration against the Property Trustee.  In case an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6), the Property Trustee shall exercise such of the rights and powers
vested in it by this Declaration, and use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

          (b)  No provision of this Declaration shall be construed to relieve
the Property Trustee from liability for its own

                                      -17-
<PAGE>
 
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

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

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

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

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

          (iii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a Majority in liquidation
     amount of the Securities at the time outstanding relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Property Trustee, or exercising any trust or power conferred upon the
     Property Trustee under this Declaration;

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

                                      -18-
<PAGE>
 
          (v)  the Property Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Debentures and the Property
     Trustee Account shall be to deal with such property in a similar manner as
     the Property Trustee deals with similar property for its own account,
     subject to the protections and limitations on liability afforded to the
     Property Trustee under this Declaration, the Trust Indenture Act;

          (vi)  the Property Trustee shall have no duty or liability for or with
     respect to the value, genuineness, existence or sufficiency of the
     Debentures or the payment of any taxes or assessments levied thereon or in
     connection therewith;

          (vii)  the Property Trustee shall not be liable for any interest on
     any money received by it except as it may otherwise agree with the Sponsor.
     Money held by the Property Trustee need not be segregated from other funds
     held by it except in relation to the Property Trustee Account maintained by
     the Property Trustee pursuant to Section 3.8(c)(i) and except to the extent
     otherwise required by law; and

          (viii)  the Property Trustee shall not be responsible for monitoring
     the compliance by the Regular Trustees or the Sponsor with their respective
     duties under this Declaration, nor shall the Property Trustee be liable for
     the default or misconduct of the Regular Trustees or the Sponsor.

          SECTION 3.10.  Certain Rights of Property Trustee.  (a)  Subject to
the provisions of Section 3.9:

          (i)  the Property Trustee may rely, and shall be fully protected in
     acting or refraining from acting, upon any resolution, certificate,
     statement, instrument, opinion, report, notice, request, direction,

     Trustee shall deem it desirable that a matter be proved or established
     before taking, suffering or omitting any action hereunder, the Property
     Trustee (unless other evidence is herein specifically prescribed) may, in
     the absence of bad faith on its part and, if the Trust is excluded from the
     definition of Investment Company solely by means of Rule 3a-7, subject to
     the requirements of Rule 3a-7, request and rely upon an Officers'
     Certificate which, upon

                                      -19-
<PAGE>
 
     receipt of such request, shall be promptly delivered by the Sponsor or the
     Regular Trustees;

          (iv)  the Property Trustee shall have no duty to see to any recording,
     filing or registration of any instrument including, but not limited to, any

     laws (or any rerecording, refiling or registration thereof);

          (v)  the Property Trustee may consult with counsel or experts and the
     written advice or opinion of such counsel or other expert with respect to
     legal matters or advice within the scope of such expert's area of expertise
     shall be full and complete authorization and protection in respect of any
     action taken, suffered or omitted by it hereunder in good faith and in
     accordance with such advice or opinion; and the Property Trustee shall have
     the right at any time to seek instructions concerning the administration of
     this Declaration from any court of competent jurisdiction;

          (vi)  the Property Trustee shall be under no obligation to exercise 
     any rights or powers vested in it under this Declaration at the request or
     discretion of any Holder, unless such Holder shall have provided to the
     Property Trustee adequate security and indemnity which would satisfy a
     reasonable person in the position of the Property Trustee, against the
     costs, expenses (including attorneys' fees and expenses) and liabilities
     that might be incurred by it in compliance with such request or direction,
     including such reasonable advances as may be requested by the Property
     Trustee, provided that nothing contained in this Section 3.10(a)(vi) shall
     be taken to relieve the Property Trustee, upon the occurrence of an Event
     of Default, from exercising the rights and powers vested in it by this
     Declaration;

          (vii)  the Property Trustee shall not be bound to make any

     certificate, statement, instrument, opinion, report, notice, request,

     or matters as it may see fit;

          (viii)  the Property Trustee may execute any of the trusts or powers

     with due care by it hereunder;

          (ix)  any action taken by the Property Trustee or its agents hereunder
     shall bind the Trust and the Holders of the

                                      -20-
<PAGE>
 
     Securities and the signature of the Property Trustee or its agents alone
     shall be sufficient and effective to perform any such action; and no third
     party shall be required to inquire as to the authority of the Property
     Trustee to so act, or as to its compliance with any of the terms and
     provisions of this Declaration, both of which shall be conclusively
     evidenced by the Property Trustee's or its agent's taking such action;

          (x)  whenever in the administration of this Declaration the Property
     Trustee shall deem it desirable to receive instructions with respect to
     enforcing any remedy or right or taking any other action hereunder, the

     Securities of such class required under the terms of the Securities to
     direct the Property Trustee to enforce such remedy or right or take such
     action, (ii) may refrain from enforcing such remedy or right or taking such

duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation.  No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

          SECTION 3.11.  Delaware Trustee.  Notwithstanding any other provision
of this Declaration other than Section 5.2, the Delaware Trustee shall not be
entitled to exercise any powers, nor shall the Delaware Trustee have any of the
duties and responsibilities of the Regular Trustees and the Property Trustee
described in this Declaration.  Except as set forth in Section 5.2, the Delaware

          SECTION 3.13.  Not Responsible for Recitals or Issuance of Securities.
The recitals contained in this Declaration and the Securities shall be taken as
the statements of the Sponsor and the Trustees do not assume any responsibility
for their correctness.  The Trustees make no representations as to the value or
condition of the property of the Trust or any part thereof.  The Trustees make
no representations as to the validity or sufficiency of this Declaration or the
Securities.

          SECTION 3.14.  Duration of Trust.  The Trust, unless terminated
pursuant to the provisions of Article VIII hereof, shall have existence for
forty-five (45) years from the Closing Date.

          SECTION 3.15.  Mergers.  (a)  The Trust may not consolidate,
amalgamate, merge with or into, or be replaced by, or convey, transfer or lease
its properties and assets substantially as an entirety to any corporation or

          (b)  The Trust may, with the consent of the Regular Trustees or, if
there are more than two, a majority of the Regular Trustees and without the
consent of the Holders of the Securities, consolidate, amalgamate, merge with or
into, or be replaced by a trust organized as such under the laws of any State;
provided that:

          (i)  such successor entity (the "Successor Entity") either:

               (A)  expressly assumes all of the obligations of the Trust under
          the Trust Securities; or

               (B)  substitutes for the Preferred Securities other securities
          having substantially the same terms as the Preferred Securities and
          Common Securities, respectively (the "Successor Securities") so long
          as the Successor Securities rank the same as the Preferred Securities
          and Common Securities rank with respect to Distributions and payments
          upon liquidation, redemption, maturity and otherwise;

          (ii)  the Debenture Issuer expressly acknowledges a trustee of the
     Successor Entity which possesses the same powers and duties as the Property
     Trustee as the Holder of the Debentures;

          (iii)  the Preferred Securities or any 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 Preferred Securities are then listed;

                                      -22-
<PAGE>
 
          (iv)  such merger, consolidation, amalgamation or replacement does not
     cause the Preferred Securities (including any Successor Securities) to be
     downgraded by any nationally recognized statistical rating organization;

          (v)  such merger, consolidation, amalgamation or replacement does not
     adversely affect the rights, preferences and privileges of the Holders of
     the Securities (including any Successor Securities) in any material respect
     (other than with respect to any dilution of the Holders' interest in the
     new entity);

          (vi)  such successor entity has a purpose identical to that of the
     Trust;

          (vii)  prior to such merger, consolidation, amalgamation or 
     replacement, the Sponsor has received an opinion from independent counsel
     to the Trust experienced in such matters to the effect that:

               (A)  such merger, consolidation, amalgamation or replacement does
          not adversely affect the rights, preferences and privileges of the
          Holders of the Securities (including any Successor Securities) in any
          material respect (other than with respect to any dilution of the
          Holders' interest in the new entity); and

               (B)  following such merger, consolidation, amalgamation or
          replacement, neither the Trust nor the Successor Entity will be
          required to register as an Investment Company; and

          (viii)  the Sponsor guarantees the obligations of such Successor
     Entity under the Successor Securities at least to the extent provided by
     the Preferred Securities Guarantee.

          (c)  Notwithstanding Section 3.15(b), the Trust shall not consolidate,
amalgamate, merge with or into, or be replaced by any other entity or permit any
other entity to consolidate, amalgamate, merge with or into, or replace it if
such consolidation, amalgamation, merger or replacement would cause the Trust or
Successor Entity for United States federal income tax purposes to be classified
as other than a grantor trust and each Holder of the Securities not to be
treated as owning an undivided beneficial interest in the Debentures, except
with the consent of Holders of 100% in liquidation amount of the Securities.

     ($50,000,000), and subject to supervision or examination by federal, state,
     territorial or District of Columbia authority (if such corporation
     publishes reports of condition at least annually, pursuant to law or to the
     requirements of the supervising or examining authority referred to above,
     then for the purposes of this Section 5.3(a)(ii), the combined capital and

obligor referred to in Section 310(b) of the Trust Indenture Act) shall in all

Act.

          SECTION 5.4.  Qualifications of Regular Trustees and Delaware Trustee

Trustee has been appointed and has accepted

                                      -26-
<PAGE>
 
     such appointment by written instrument executed by such Successor Property
     Trustee and delivered to the Regular Trustees and the Sponsor; and

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

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

               (A)  a Successor Property Trustee has been appointed and has
          accepted such appointment by instrument executed by such Successor
          Property Trustee and delivered to the Trust and the Sponsor; or

               (B)  if the Trust is deemed not to be an Investment Company
          solely by reason of Rule 3a-7, until the assets of the Trust have been
          completely liquidated and the proceeds thereof distributed to the
          holders of the Securities; and

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

          (d) The Holders of the Common Securities shall use their best efforts
to promptly appoint a Successor Delaware Trustee or Successor Property Trustee
as the case may be if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 5.6.

          (e) If no Successor Property Trustee or Successor Delaware Trustee
shall have been appointed and accepted appointment as provided in this Section
5.6 within 60 days after delivery to the Sponsor and the Trust of an instrument
of resignation, the resigning Property Trustee or Delaware Trustee, as
applicable, may petition any court of competent jurisdiction for appointment of
a

                                      -27-
<PAGE>
 
Successor Property Trustee or Successor Delaware Trustee.  Such court may
thereupon, after prescribing such notice, if any, as it may deem proper and
prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be.

          SECTION 5.7.  Vacancies among Trustees.  If a Trustee ceases to hold
office for any reason and the number of Trustees is not reduced pursuant to
Section 5.1, or if the number of Trustees is increased pursuant to Section 5.1,
a vacancy shall occur.  A resolution certifying the existence of such vacancy by
a majority of the Regular Trustees shall be conclusive evidence of the existence
of such vacancy.  The vacancy shall be filled with a Trustee appointed in
accordance with Section 5.6.

          SECTION 5.8.  Effect of Vacancies.  The death, resignation,
retirement, removal, bankruptcy, dissolution, liquidation, incompetence or
incapacity to perform the duties of a Trustee, or any one of them, shall not
operate to annul the Trust.  Whenever a vacancy in the number of Regular
Trustees shall occur, until such vacancy is filled by the appointment of a
Regular Trustee in accordance with Section 5.6, the Regular Trustees in office,
regardless of their number, shall have all the powers granted to the Regular
Trustees and shall discharge all the duties imposed upon the Regular Trustees by
this Declaration.

          SECTION 5.9.  Meetings.  Meetings of the Regular Trustees shall be
held from time to time upon the call of any Regular Trustee.  Regular meetings
of the Regular Trustees may be held at a time and place fixed by resolution of
the Regular Trustees.  Notice of any in-person meetings of the Regular Trustees
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 48 hours before
such meeting.  Notice of any telephonic meetings of the Regular Trustees or any
committee thereof shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 24
hours before a meeting.  Notices shall contain a brief statement of the time,
place and anticipated purposes of the meeting.  The presence (whether in person
or by telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened.  Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided that a Quorum is present, or without a meeting by the unanimous written
consent of the Regular Trustees.  In the event there is only one Regular
Trustee, any action of such Regular Trustee shall be evidenced by a written
consent of such Regular Trustee.

          SECTION 5.10.  Delegation of Power.  (a)  Any Regular Trustee may, by
power of attorney consistent with applicable law, delegate to any other natural
person over the age of 21 his or her power for the purpose of executing any
documents contemplated in Section 3.6, including any registration statement or
amendment thereto filed with the Commission or making any other governmental
filing.

          (b)  The Regular Trustees shall have power to delegate from time to
time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Regular Trustees or otherwise as the Regular Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of the Trust, as set forth herein.


                                   ARTICLE VI
                                 DISTRIBUTIONS

          SECTION 6.1.  Distributions.  Holders shall receive Distributions in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective
terms.  If and to the extent that the Debenture Issuer makes a payment of
interest (including Compounded Interest (as defined in the Indenture) and
Additional Interest (as defined in the Indenture)), premium and principal on the
Debentures held by the Property Trustee (the amount of any such payment being a
"Payment Amount"), the Property Trustee shall and is directed, to the extent
funds are available for that purpose, to make a Distribution of the Payment
Amount to the Holders.


                                  ARTICLE VII
                             ISSUANCE OF SECURITIES

          SECTION 7.1.  General Provisions Regarding Securities.  (a)  The
Regular Trustees shall, on behalf of the Trust, issue one class of preferred
securities representing undivided beneficial interests in the assets of the
Trust having such terms as are set forth in Exhibit A and incorporated herein by
reference (the "Preferred Securities"), and one class of common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Exhibit A and incorporated herein by reference
(the "Common Securities").  The Trust shall have no securities or other
interests in the assets of the Trust other than the Preferred Securities and the
Common Securities.

                                      -29-
<PAGE>
 
          (b)  The Securities shall be signed on behalf of the Trust by the
Regular Trustees (or, if there are more than two Regular Trustees, by any two of
the Regular Trustees).  Such signatures may be the manual or facsimile
signatures of the present or any future Regular Trustee.  Typographical and
other minor errors or defects in any such reproduction of any such signature
shall not affect the validity of any Security.  In case any Regular Trustee of
the Trust who shall have signed any of the Securities shall cease to be such
Regular Trustee before the Security so signed shall be delivered by the Trust,
such Security nevertheless may be delivered as though the person who signed such
Security had not ceased to be such Regular Trustee; and any Security may be
signed on behalf of the Trust by such persons as, at the actual date of the
execution of such Security, the Regular Trustees of the Trust, although at the
date of the execution and delivery of the Declaration any such person was not
such a Regular Trustee.

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

          (d)  Upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be deemed to be validly issued, fully paid and
non-assessable, subject to Section 10.1(b) with respect to the Common
Securities.

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


                                  ARTICLE VIII
                              TERMINATION OF TRUST

          SECTION 8.1.  Termination of Trust.  (a)  The Trust shall terminate:

          (i)  upon the bankruptcy of the Holder of the Common Securities or the
     Sponsor;

         (ii)  upon the filing of a certificate of dissolution or its equivalent
     with respect to the Holder of the Common Securities or the Sponsor, the
     filing of a certificate of cancellation with respect to the Trust or the
     revocation of the Holder of the Common Securities or the Sponsor's charter
     and the expiration of ninety (90) days after the date of revocation without
     a reinstatement thereof;

        (iii)  upon the entry of a decree of judicial dissolution of the Holder
     of the Common Securities, the Sponsor or the Trust;

                                      -30-
<PAGE>
 
         (iv)  when all of the Securities shall have been called for redemption
     and the amounts necessary for redemption thereof shall have been paid to
     the Holders in accordance with the terms of the Securities;

          (v)  upon the occurrence and continuation of a Special Event pursuant
     to which the Trust shall have been dissolved in accordance with the terms
     of the Securities and all of the Debentures shall have been distributed to
     the Holders of Securities in exchange for all of the Securities; or

         (vi)  before the issuance of any Securities, with the consent of all of
     the Regular Trustees and the Sponsor.

          (b)  As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a), the Trustees shall file a certificate of
cancellation with the Secretary of State of the State of Delaware.

          (c)  The provisions of Article X shall survive the termination of the
Trust.


                                   ARTICLE IX
                             TRANSFER OF INTERESTS

          SECTION 9.1.  Transfer of Securities.  (a)  Securities may only be
transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration and in the terms of the Securities.  Any transfer
or purported transfer of any Security not made in accordance with this
Declaration shall be null and void.

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

          (c)  Subject to this Article IX, the Sponsor and any Related Party may
only transfer Common Securities to the Sponsor or a Related Party of the
Sponsor, provided that any such transfer is subject to the condition precedent
that the transferor obtain the written opinion of nationally recognized
independent counsel experienced in such matters that such transfer would not
cause more than an insubstantial risk that:

          (i)  the Trust would not be classified for United States federal
     income tax purposes as a grantor trust and each Holder of Securities would
     not be treated as owning an undivided beneficial interest in the
     Debentures; and

          (ii)  the Trust would be an Investment Company or the transferee would
     be an Investment Company if the transferee was not an Investment Company
     before the transfer.

                                      -31-

          SECTION 9.2.  Transfer of Certificates.  The Regular Trustees shall
provide for the registration of Certificates and of transfers of Certificates,
which will be effected without charge but only upon payment (with such indemnity
as the Regular Trustees may require) in respect of any tax or other government
charges which may be imposed in relation to it.  Upon surrender for registration
of transfer of any Certificate, the Regular Trustees shall cause one or more new
Certificates to be issued in the name of the designated transferee or
transferees.  Every Certificate surrendered for registration of transfer shall
be accompanied by a written instrument of transfer in form satisfactory to the
Regular Trustees duly executed by the Holder or such Holder's attorney duly
authorized in writing.  Each Certificate surrendered for registration of
transfer shall be canceled by the Regular Trustees.  A transferee of a
Certificate shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee of a Certificate.  By
acceptance of a Certificate, each transferee shall be deemed to have agreed to
be bound by this Declaration and the documents incorporated by reference herein.

          SECTION 9.3.  Deemed Security Holders.  The Trustees may treat the
Person in whose name any Certificate shall be registered on the books and
records of the Trust as the sole holder of such Certificate and of the
Securities represented by such Certificate for purposes of receiving
Distributions and for all other purposes whatsoever and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such
Certificate or in the Securities represented by such Certificate on the part of
any Person, whether or not the Trustees shall have actual or other notice
thereof.

          SECTION 9.4.  Book Entry Interests.  Unless otherwise specified in the
terms of the Preferred Securities, the Preferred Securities Certificates, on
original issuance, will be issued in the form of one or more, fully registered,
global Preferred Security Certificates (each a "Global Certificate"), to be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust.
Such Global Certificates shall initially be registered on the books and records
of the Trust in the name of Cede & Co., the nominee of DTC, and no Preferred
Security Beneficial Owner will receive a definitive Preferred Security
Certificate representing such  Preferred Security Beneficial Owner's interests
in such Global Certificates, except as provided in Section 9.7.  Unless and
until definitive, fully registered Preferred Security Certificates (the
"Definitive Preferred Security Certificates") have been issued to the Preferred
Security Beneficial Owners pursuant to Section 9.7:

          (a)  the provisions of this Section 9.4 shall be in full force and
     effect;

          (b)  the Trust and the Trustees shall be entitled to deal with the
     Clearing Agency for all purposes of this Declaration

                                      -32-
<PAGE>
 
     (including the payment of Distributions on the Global Certificates and
     receiving approvals, votes or consents hereunder) as the Holder of the
     Preferred Securities and the sole holder of the Global Certificates and
     shall have no obligation to the Preferred Security Beneficial Owners;

          (c)  to the extent that the provisions of this Section 9.4 conflict
     with any other provisions of this Declaration, the provisions of this
     Section 9.4 shall control; and

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

          SECTION 9.5.  Notices to Clearing Agency.  Whenever a notice or other
communication to the Preferred Security Holders is required under this
Declaration, unless and until Definitive Preferred Security Certificates shall
have been issued to the Preferred Security Beneficial Owners pursuant to Section
9.7, the Regular Trustees shall give all such notices and communications
specified herein to be given to the Preferred Security Holders to the Clearing
Agency, and shall have no notice obligations to the Preferred Security
Beneficial Owners.

          SECTION 9.6.  Appointment of Successor Clearing Agency.  If any
Clearing Agency elects to discontinue its services as securities depositary with
respect to the Preferred Securities, the Regular Trustees may, in their sole
discretion, appoint a successor Clearing Agency with respect to such Preferred
Securities.

          SECTION 9.7.  Definitive Preferred Security Certificates.  

If:

          (a)  a Clearing Agency elects to discontinue its services as
     securities depositary with respect to the Preferred Securities and a
     successor Clearing Agency is not appointed within ninety (9O) days after
     such discontinuance pursuant to Section 9.6; or

          (b)  the Regular Trustees elect, after consultation with the Sponsor,
     to terminate the book entry system through the Clearing Agency with respect
     to the Preferred Securities,

then:

                                      -33-
<PAGE>
 
          (c)  Definitive Preferred Security Certificates shall be prepared by
     the Regular Trustees on behalf of the Trust with respect to such Preferred
     Securities; and

          (d)  upon surrender of the Global Certificates by the Clearing Agency,
     accompanied by registration instructions, the Regular Trustees shall cause
     Definitive Preferred Security Certificates to be delivered to Preferred
     Security Beneficial Owners in accordance with the instructions of the
     Clearing Agency.  Neither the Trustees nor the Trust shall be liable for
     any delay in delivery of such instructions and each of them may
     conclusively rely on, and shall be protected in relying on, such
     instructions.  The Definitive Preferred Security Certificates shall be
     printed, lithographed or engraved or may be produced in any other manner as
     is reasonably acceptable to the Regular Trustees, as evidenced by their
     execution thereof, and may have such letters, numbers or other marks of
     identification or designation and such legends or endorsements as the
     Regular Trustees may deem appropriate, or as may be required to comply with
     any law or with any rule or regulation made pursuant thereto or with any
     rule or regulation of any stock exchange on which Preferred Securities may
     be listed, or to conform to usage.

          SECTION 9.8.  Mutilated, Destroyed, Lost or Stolen Certificates.  If:

          (a)  any mutilated Certificates should be surrendered to the Regular
     Trustees, or if the Regular Trustees shall receive evidence to their
     satisfaction of the destruction, loss or theft of any Certificate; and

          (b)  there shall be delivered to the Regular Trustees such security or
     indemnity as may be required by them to keep each of them harmless,

then in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any two Regular Trustees on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 9.8,
the Regular Trustees may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection therewith.
Any duplicate Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the relevant Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                           LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

          SECTION 10.1.  Liability.  (a)  Except as expressly set forth in this
Declaration, the Debentures, the Securities Guarantees and the terms of the
Securities, the Sponsor shall not be:

          (i)  personally liable for the return of any portion of the capital
     contributions (or any return thereon) of the Holders of the Securities
     which shall be made solely from assets of the Trust; and

          (ii)  be required to pay to the Trust or to any Holder of Securities
     any deficit upon dissolution of the Trust or otherwise.

          (b)  The Holder of the Common Securities shall be liable for all of
the debts and obligations of the Trust (other than with respect to the
Securities) to the extent not satisfied out of the Trust's assets.

          SECTION 10.2.  Exculpation.  (a)  No Indemnified Person shall be
liable, responsible or accountable in damages or otherwise to the Trust or any
Covered Person for any loss, damage or claim incurred by reason of any act or
omission performed or omitted by such Indemnified Person in good faith on behalf
of the Trust and in a manner such Indemnified Person reasonably believed to be
within the scope of the authority conferred on such Indemnified Person by this
Declaration or by law, except that an Indemnified Person shall be liable for any
such loss, damage or claim incurred by reason of such Indemnified Person's gross
negligence (or, in the case of the Property Trustee, pursuant to Section 3.9,
negligence) or willful misconduct with respect to such acts or omissions.

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

          SECTION 10.3.  Fiduciary Duty.  (a)  To the extent that, at law or in
equity, an Indemnified Person has duties (including fiduciary duties) and
liabilities relating thereto to the Trust or to any other Covered Person, an
Indemnified Person acting under this Declaration, subject to any duties or
obligations imposed on

                                      -35-
<PAGE>
 
the Property Trustee under Rule 3a-7, shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration.  The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than duties imposed on the Property Trustee under the
Trust Indenture Act), are agreed by the parties hereto to replace such other
duties and liabilities of such Indemnified Person.

          (b)  Unless otherwise expressly provided herein:

          (i)  whenever a conflict of interest exists or arises between an
     Indemnified Person and Covered Persons; or

          (ii)  whenever this Declaration or any other agreement contemplated
     herein or therein provides that an Indemnified Person shall act in a manner
     that is, or provides terms that are, fair and reasonable to the Trust or
     any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

          (c)  Whenever in this Declaration an Indemnified Person is permitted
or required to make a decision:

          (i)  in its "discretion" or under a grant of similar authority, the
     Indemnified Person shall be entitled to consider such interests and factors
     as it desires, including its own interests, and shall have no duty or
     obligation to give any consideration to any interest of, or factors
     affecting, the Trust or any other Person; or

          (ii)  in its "good faith" or under another express standard, the
     Indemnified Person shall act under such express standard and shall not be
     subject to any other or different standard imposed by this Declaration or
     by applicable law.

          SECTION 10.4.  Indemnification.  (a)  To the fullest extent permitted
by applicable law, the Sponsor shall indemnify and hold harmless each
Indemnified Person from and against any loss, damage, liability, tax, penalty,
expense or claim incurred by such

                                      -36-
<PAGE>
 
Indemnified Person by reason of the creation, operation or termination of the
Trust or any act or omission performed or omitted by such Indemnified Person in
good faith on behalf of the Trust and in a manner such Indemnified Person
reasonably believed to be within the scope of authority conferred on such
Indemnified Person by this Declaration, except that no Indemnified Person shall
be entitled to be indemnified in respect of any loss, damage or claim incurred
by such Indemnified Person by reason of gross negligence (or, in the case of the
Property Trustee, pursuant to Section 3.9, negligence) or willful misconduct
with respect to such acts or omissions.

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

          SECTION 10.5.  Outside Businesses.  Any Covered Person, the Sponsor,
the Delaware Trustee and the Property Trustee may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, similar or dissimilar to the business of the Trust, and the
Trust and the Holders of Securities shall have no rights by virtue of this
Declaration in and to such independent ventures or the income or profits derived
therefrom and the pursuit of any such venture, even if competitive with the
business of the Trust, shall not be deemed wrongful or improper.  No Covered
Person, the Sponsor, the Delaware Trustee or the Property Trustee shall be
obligated to present any particular investment or other opportunity to the Trust
even if such opportunity is of a character that, if presented to the Trust,
could be taken by the Trust, and any Covered Person, the Sponsor, the Delaware
Trustee and the Property Trustee shall have the right to take for its own
account (individually or as a partner or fiduciary) or to recommend to others
any such particular investment or other opportunity.  Any Covered Person, the
Delaware Trustee and the Property Trustee may engage or be interested in any
financial or other transaction with the Sponsor or any Affiliate of the Sponsor,
or may act as depository for, trustee or agent for, or act on any committee or
body of holders of, securities or other obligations of the Sponsor or its
Affiliates.

                                   ACCOUNTING

          SECTION 11.1.  Fiscal Year.  The fiscal year ("Fiscal Year") of the
Trust shall be the calendar year, or such other year as is required by the Code.

          SECTION 11.2.  Certain Accounting Matters.  (a)  At all times during
the existence of the Trust, the Regular Trustees shall keep, or cause to be
kept, full books of account, records and supporting documents, which shall
reflect in reasonable detail, each transaction of the Trust.  The books of
account shall be maintained on the accrual method of accounting, in accordance
with generally accepted accounting principles, consistently applied.  The Trust
shall use the accrual method of accounting for United States federal income tax
purposes.  The books of account and the records of the Trust shall be examined
by and reported upon as of the end of each Fiscal Year of the Trust by a firm of
independent certified public accountants selected by the Regular Trustees.

          (b)  The Regular Trustees shall cause to be prepared and delivered to
each of the Holders of Securities, within 90 days after the end of each Fiscal
Year of the Trust, annual financial statements of the Trust, including a balance
sheet of the Trust as of the end of such Fiscal Year, and the related statements
of income or loss.

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

          (d)  The Regular Trustees shall cause to be duly prepared and filed
with the appropriate taxing authority, an annual United States federal income
tax return, on a Form 1041 or such other form required by United States federal
income tax law, and any other annual income tax returns required to be filed by
the Regular Trustees on behalf of the Trust with any state or local taxing
authority.

          SECTION 11.3.  Banking.  The Trust shall maintain one or more bank
accounts in the name and for the sole benefit of the Trust; provided, however,
that all payments of funds in respect of the Debentures held by the Property
Trustee shall be made directly to the Property Trustee Account and no other
funds of the Trust shall be deposited in the Property Trustee Account.  The sole
signatories for such accounts shall be designated by the Regular

                                      -38-
<PAGE>
 
Trustees; provided, however, that the Property Trustee shall designate the
signatories for the Property Trustee Account.

          SECTION 11.4.  Withholding.  The Trust and the Trustees shall comply
with all withholding requirements under United States federal, state and local
law.  The Trust shall request, and the Holders shall provide to the Trust, such
forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations.  The Regular
Trustee(s) shall file required forms with applicable jurisdictions and, unless
an exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions.  To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to distributions or allocations to any Holder, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to the Holder.  In the event of any claimed over with-holding, Holders shall be
limited to an action against the applicable jurisdiction.  If the amount
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

Declaration or by any applicable terms of the Securities, this Declaration may
be amended by, and only by, a written instrument approved and executed by the
Regular Trustees (or, if there are more than two Regular Trustees, a majority of
the Regular Trustees); provided, however, that:

          (i)  no amendment shall be made, and any such purported amendment
     shall be void and ineffective:

               (1)  unless, in the case of any proposed amendment, the Property
                    Trustee shall have first received an Officers' Certificate
                    from each of the Trust and the Sponsor that such amendment
                    is permitted by, and conforms to, the terms of this
                    Declaration (including the terms of the Securities);

               (2)  unless, in the case of any proposed amendment with affects
                    the rights, powers, duties, obligations or immunities of the
                    Property Trustee, the Property Trustee shall have first
                    received:

          terms of this Declaration (including the terms of the Securities); and

          (ii)  no amendment shall be made, and any such purported amendment
     shall be void and ineffective, to the extent the result thereof would be to

               (A)  cause the Trust not to be characterized for purposes of
          United States federal income taxation as a grantor trust and each
          Holder of Securities not to be treated as owning an undivided
          beneficial interest in the Debentures, as evidenced by an Opinion of
          Counsel to the effect that such amendment shall not result in the

          which is required to be registered under the Investment Company Act;

          (iii)  at such time after the Trust has issued any Securities which
     remain outstanding, any amendment which would adversely affect the rights,
     privileges or preferences of any Holder of Securities may be effected only
     with such additional requirements as may be set forth in the terms of such
     Securities;

          (iv)  Section 9.1(c) and this Section 12.1 shall not be amended 
     without the consent of all of the Holders of the Securities;

          (v)  Article IV shall not be amended without the consent of the 
     Holders of a Majority in liquidation amount of the Common Securities; and

          (vi)  the rights of the holders of the Common Securities under Article
     V to increase or decrease the number of, and appoint and remove, Trustees
     shall not be amended without the consent of the Holders of a Majority in
     liquidation amount of the Common Securities.

          (b)  Notwithstanding Section 12.1(a)(ii), this Declaration may be
amended without the consent of the Holders of the Securities to:

          (i)  cure any ambiguity;

          (ii)  correct or supplement any provision in this Declaration that may
     be defective or inconsistent with any other provision of this Declaration;

          (iii)  to add to the covenants, restrictions or obligations of the

          (iv)  to conform to any change in Rule 3a-7 or written change in
     interpretation or application of Rule 3a-7 by any legislative body, court,
     government agency or regulatory authority which amendment does not have a
     material adverse effect on the right, preferences or privileges of the
     Holders.

          SECTION 12.2.  Meetings of the Holders of Securities; Action by
Written Consent.  (a)  Meetings of the Holders of any class of Securities may be
called at any time by the Regular Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Preferred
Securities are listed or admitted for trading.  The Regular Trustees shall call
a meeting of such class of Holders, if directed to do so by the Holders of at
least 10% in liquidation amount of such class of Securities.  Such direction
shall be given by delivering to the Regular Trustees one or more calls in a
writing stating that the signing Holders of Securities wish to call a meeting
and indicating the general or specific purpose for which the meeting is to be
called.  Any Holders of Securities calling a meeting shall specify in writing
the Security Certificates held by the Holders of Securities exercising the right
to call a meeting and only those specified shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

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

          (i)  Notice of any such meeting shall be given to all the Holders of
     Securities having a right to vote thereat at least seven (7) days and not
     more than sixty (60) days before the date of such meeting.  Whenever a
     vote, consent or approval of the Holders of Securities is permitted or
     required under this Declaration or the rules of any stock exchange on which
     the Preferred Securities are listed or admitted for trading, such vote,
     consent or approval may be given at a meeting of the Holders of Securities.
     Any action that may be taken at a

                                      -41-
<PAGE>
 
     meeting of the Holders of Securities may be taken without a meeting if a
     consent in writing setting forth the action so taken is signed by the
     Holders of Securities owning not less than the minimum amount of Securities
     in liquidation amount that would be necessary to authorize or take such
     action at a meeting at which all Holders of Securities having a right to
     vote thereon were present and voting.  Prompt notice of the taking of
     action without a meeting shall be given to the Holders of Securities
     entitled to vote who have not consented in writing.  The Regular Trustees
     may specify that any written ballot submitted to the Security Holder for
     the purpose of taking any action without a meeting shall be returned to the
     Trust within the time specified by the Regular Trustees.

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

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

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

The Trustee which acts as initial Property Trustee represents and warrants to
the Trust and to the Sponsor at the date of this Declaration, and each Successor
Property Trustee represents and warrants to the Trust and the Sponsor at the
time of the Successor Property Trustee's acceptance of its appointment as
Property Trustee that:

          (a)  The Property Trustee is a Delaware banking association with trust
     powers, duly organized, validly existing and in good standing under the
     laws of the State of Delaware, with trust power and authority to execute
     and deliver, and to carry out and perform its obligations under the terms
     of, the Declaration.

          (b)  The execution, delivery and performance by the Property Trustee
     of the Declaration has been duly authorized by all necessary corporate
     action on the part of the Property Trustee.  The Declaration has been duly
     executed and delivered by the Property Trustee, and it constitutes a legal,
     valid and binding obligation of the Property Trustee, enforceable against
     it in accordance with its terms, subject to applicable bankruptcy,
     reorganization, moratorium, insolvency and other similar laws affecting
     creditors' rights generally and to general principles of equity and the
     discretion of the court (regardless of whether the enforcement of such
     remedies is considered in a proceeding in equity or at law).

          (c)  The execution, delivery and performance of the Declaration by the
     Property Trustee does not conflict with or constitute a breach of the
     Articles of Organization or By-Laws of the Property Trustee.

          (d)  No consent, approval or authorization of, or registration with or
     notice to, any State or Federal banking authority is required for the
     execution, delivery or performance by the Property Trustee of the
     Declaration.

          (e)  The Delaware Trustee has been authorized to perform its
     obligations under the Certificate of Trust and the Declaration.  The
     Declaration under Delaware law constitutes a legal, valid and binding
     obligation of the Delaware Trustee, enforceable against it in accordance
     with its terms, subject to applicable bankruptcy, reorganization,
     moratorium, insolvency and other similar laws affecting creditors' rights
     generally and to general principles of equity and the

                                      -43-
<PAGE>
 
     discretion of the court (regardless of whether the enforcement of such
     remedies is considered in a proceeding in equity or at law).


                                  ARTICLE XIV

          SECTION 14.3.  Intention of the Parties.  It is the intention of the

beneficial interest in the Debentures.  The provisions of this Declaration shall
be interpreted to further this intention of the parties.

Declaration, or the application of such provision to any Person or circumstance,

such provision to persons or circumstances other than those to which it is held

          SECTION 14.7.  Counterparts.  This Declaration may contain more than
one counterpart of the signature page and this Declaration may be executed by
the affixing of the signature of each of the Trustees to one of such counterpart
signature pages.  All of such counterpart signature pages shall be read as

signers had signed a single signature page.

          IN WITNESS WHEREOF, the undersigned has caused these presents to be
executed as of the day and year first above written.

                                   TERMS OF
                   __% TRUST ORIGINATED PREFERRED SECURITIES
                    __% TRUST ORIGINATED COMMON SECURITIES

          Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of ________, 1995 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Preferred Securities and the Common
Securities are set out below (each capitalized term used but not defined herein
has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):


          1.  Designation and Number.

          (a)  Preferred Securities.  Preferred Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of $ ____
million ($ ____) and a liquidation amount with respect to the assets of the
Trust of $25 per Preferred Security, are hereby designated for the purposes of
identification only as "___% Trust Originated Preferred Securities" (the
"Preferred Securities").  The Preferred Security Certificates evidencing the
Preferred Securities shall be substantially in the form attached hereto as Annex
I, with such changes and additions thereto or deletions therefrom as may be
required by ordinary usage, custom or practice.

          (b)  Common Securities.  Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of $ ____
million ($ ____) and a liquidation amount with respect to the assets of the
Trust of $25 per Common Security, are hereby designated for the purposes of
identification only as "___% Trust Originated Common Securities" (the "Common
Securities").  The Common Security Certificates evidencing the Common Securities
shall be substantially in the form attached hereto as Annex II, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

          2.  Distributions.  (a)  Distributions payable on each Security will
be fixed at a rate per annum of ____% (the "Coupon Rate") of the stated
liquidation amount of $25 per Security, such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee.  Distributions in
arrears will bear interest compounded quarterly at the Coupon Rate (to the
extent permitted by applicable law).  The term "Distributions," as used herein,
includes any such interest payable unless otherwise
<PAGE>
 
stated.  A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee.  The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period, on the basis
of the actual number of days elapsed in such a 90-day quarter.

          (b)  Distributions on the Securities will be cumulative, will accrue
from ________, 1995 and will be payable quarterly in arrears, on March 31, June
30, September 30, and December 31 of each year, commencing on ________, 1995,
except as otherwise described below.  The Debenture Issuer has the right under
the Indenture to defer payments of interest by extending the interest payment
period from time to time on the Debentures for a period not exceeding twenty
consecutive quarters (each such period, an "Extension Period") and, as a
consequence of such extension, Distributions will also be deferred.  Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Coupon Rate,
compounded quarterly during any such Extension Period.  Prior to the termination
of any such Extension Period, the Debenture Issuer may further extend such
Extension Period; provided that such Extension Period, together with all such
previous and further extensions thereof, may not exceed twenty consecutive
quarters or extend beyond the maturity of the Debentures.  Payments of accrued
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.

          (c)  Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the relevant
record dates.  While the Preferred Securities remain in book-entry only form,
the relevant record dates shall be one Business Day prior to the relevant
payment dates which payment dates correspond to the interest payment dates on
the Debentures.  Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment in respect of the Preferred
Securities will be made as described under the heading "Description of the
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust
Company" in the Prospectus dated ________, 1995 (the "Prospectus") of the Trust
included in the Registration Statement on Form S-3 of the Sponsor and the Trust.
The relevant record dates for the Common Securities, and if the Preferred
Securities shall not continue to remain in book-entry-only form, the relevant
record dates for the Preferred Securities, shall conform to the rules of any
securities exchange on which the securities are listed and, if none, shall be
selected by the Regular

                                     - 2 -
<PAGE>
 
Trustees, which dates shall be at least one Business Day but less than 60
Business Days before the relevant payment dates which payment dates correspond
to the interest payment dates on the Debentures.  Distributions payable on any
Securities that are not punctually paid on any Distribution payment date, as a
result of the Debenture Issuer having failed to make a payment under the
Debentures, will cease to be payable to the Person in whose name such Securities
are registered on the relevant record date, and such defaulted Distribution will
instead be payable to the Person in whose name such Securities are registered on
the special record date or other specified date determined in accordance with
the Indenture.  If any date on which Distributions are payable on the Securities
is not a Business Day, then payment of the Distribution payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date.

          (d)  In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

          3.  Liquidation Distribution Upon Dissolution.  In the event of any
voluntary or involuntary dissolution, winding-up or termination of the Trust,
the Holders of the Securities on the date of the dissolution, winding-up or
termination, as the case may be, will be entitled to receive out of the assets
of the Trust available for distribution to Holders of Securities after
satisfaction of liabilities of creditors, an amount equal to the aggregate of
the stated liquidation amount of $25 per Security plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless, in connection with such dissolution, winding-up or
termination, Debentures in an aggregate principal amount equal to the aggregate
stated liquidation amount of such Securities, with an interest rate equal to the
Coupon Rate of, and bearing accrued and unpaid interest in an amount equal to
the accrued and unpaid Distributions on, such Securities, shall be distributed
on a Pro Rata basis to the Holders of the Securities in exchange for such
Securities.

          If, upon any such dissolution, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by the Trust on the Securities shall be paid on a Pro Rata basis.

          4.  Redemption and Distribution.  (a)  Upon the   repayment of the
Debentures in whole or in part, whether at

                                     - 3 -
<PAGE>
 
maturity or upon acceleration, redemption or otherwise, the proceeds from such
repayment or payment shall be simultaneously applied to redeem Securities having
an aggregate stated liquidation amount equal to the aggregate principal amount
of the Debentures so repaid or redeemed at a redemption price of $25 per
Security plus an amount equal to accrued and unpaid Distributions thereon at the
date of the redemption, payable in cash (the "Redemption Price").  Holders will
be given not less than 30 nor more than 60 days notice of such redemption except
in the case of payments upon maturity.

          (b)  If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Section 4(f)(ii) below.

          (c)  If, at any time, a Tax Event or an Investment Company Event (each
as defined below, and each a "Special Event") shall occur and be continuing, the
Regular Trustees shall dissolve the Trust and, after satisfaction of creditors,
cause Debentures held by the Property Trustee, having an aggregate principal
amount equal to the aggregate stated liquidation amount of[, with an interest
rate identical to the Coupon Rate of], and accrued and unpaid interest equal to
accrued and unpaid Distributions on and having the same record date for payment
as, the Securities, to be distributed to the Holders of the Securities in
liquidation of such Holders' interests in the Trust on a Pro Rata basis, within
90 days following the occurrence of such Special Event (the "90 Day Period"),
provided however, that in the case of the occurrence of a Tax Event, as a
condition of such dissolution and distribution, the Regular Trustees shall have
received an opinion from independent tax counsel experienced in such matters (a
"No Recognition Opinion"), which opinion may rely on published revenue rulings
of the Internal Revenue Service, to the effect that the Holders of the
Securities will not recognize any gain or loss for United States federal income
tax purposes as a result of the dissolution of the Trust and the distribution of
the Debentures and provided further, that, if at the time there is available to
the Trust the opportunity to eliminate, within the 90 Day Period, the Special
Event by taking some ministerial action, such as filing a form or making an
election, or pursuing some other similar reasonable measure that has no adverse
effect on the Sponsor, the Trust, the Debenture Issuer or the Holders of the
Securities ("Ministerial Action"), the Trust will pursue such Ministerial Action
in lieu of dissolution.

          If, in the case of the occurrence of a Tax Event (i) the Debenture
Issuer has received an opinion (a "Redemption Tax Opinion") from independent tax
counsel experienced in such matters that, as a result of a Tax Event, there is
more than an insubstantial risk that the Debenture Issuer would be precluded
from deducting the interest on the Debentures for United States

                                     - 4 -
<PAGE>
 
federal income tax purposes even if the Debentures were distributed to the
Holders of Securities in liquidation of such Holders' interests in the Trust as
described in this Section 4(c), or (ii) the Regular Trustees shall have been
informed by such tax counsel that a No Recognition Opinion cannot be delivered
to the Trust, the Debenture Issuer shall have the right, upon not less than 30
nor more than 60 days notice, to redeem the Debentures in whole or in part for
cash within 90 days following the occurrence of such Tax Event, and following
such redemption, Securities with an aggregate stated liquidation amount equal to
the aggregate principal amount of the Debentures so redeemed shall be redeemed
by the Trust at the Redemption Price on a Pro Rata basis; provided, however,
that, if at the time there is available to the Trust the opportunity to
eliminate, within such 90 day period, the Tax Event by taking some Ministerial
Action, the Trust or the Debenture Issuer will pursue such Ministerial Action in
lieu of redemption.

          "Tax Event" means that the Regular Trustees shall have received an
opinion from independent tax counsel experienced in such matters (a "Dissolution
Tax Opinion") to the effect that, on or after the date of the Prospectus, as a
result of (a) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority therefor or therein, or (b) any
amendment to, or change in, an interpretation or application of any such laws or
regulations by any legislative body, court, governmental agency or regulatory
authority, which amendment or change is enacted, promulgated, issued or
announced or which interpretation or pronouncement is issued or announced or
which action is taken, in each case on or after the date of the Prospectus,
there is more than an insubstantial risk that (i) the Trust is or will be within
90 days of the date thereof, subject to United States federal income tax with
respect to interest accrued or received on the Debentures, (ii) the Trust is, or
will be within 90 days of the date thereof, subject to more than a de minimis
amount of other taxes, duties or other governmental charges, or (iii) interest
payable by the Debenture Issuer to the Trust on the Debentures is not, or within
90 days of the date thereof will not be, deductible, in whole or in part, by the
Debenture Issuer for United States federal income tax purposes.

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

                                     - 5 -
<PAGE>
 
Act Law becomes effective on or after the date of the Prospectus.

          On and from the date fixed by the Trustees for any distribution of
Debentures and dissolution of the Trust: (i) the Securities will no longer be
deemed to be outstanding, (ii) The Depository Trust Company (the "Depository")
or its nominee (or any successor Clearing Agency or its nominee), as the record
Holder of the Preferred Securities, will receive a registered global certificate
or certificates representing the Debentures to be delivered upon such
distribution and any certificates representing Securities, except for
certificates representing Preferred Securities held by the Depository or its
nominee (or any successor Clearing Agency or its nominee), will be deemed to
represent beneficial interests in the Debentures having an aggregate principal
amount equal to the aggregate stated liquidation amount of, with an interest
rate identical to the Coupon Rate of, and accrued and unpaid interest equal to
accrued and unpaid Distributions on, such Securities until such certificates are
presented to the Debenture Issuer or its agent for transfer or reissue.

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

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

          (f)  Redemption or Distribution Procedures. (i) Notice of any
     redemption of, or notice of distribution of Debentures in exchange for, the
     Securities (a "Redemption/Distribution Notice") will be given by the Trust
     by mail to each Holder of Securities to be redeemed or exchanged not fewer
     than 30 nor more than 60 days before the date fixed for redemption or
     exchange thereof which, in the case of a redemption, will be the date fixed
     for redemption of the Debentures.  For purposes of the calculation of the
     date of redemption or exchange and the dates on which notices are given
     pursuant to this Section 4(f)(i), a Redemption/Distribution Notice shall be
     deemed to be given on the day such notice is first mailed by first-class
     mail, postage prepaid, to Holders of Securities.  Each
     Redemption/Distribution Notice shall be addressed to the Holders of
     Securities at the address of each such Holder appearing in the books and
     records of the Trust.  No defect in the Redemption/Distribution Notice or
     in the mailing of either thereof with respect to any Holder shall affect
     the

                                     - 6 -
<PAGE>
 
     validity of the redemption or exchange proceedings with respect to any
     other Holder.

          (ii)  In the event that fewer than all the outstanding Securities are
     to be redeemed, the Securities to be redeemed shall be redeemed Pro Rata
     from each Holder of Preferred Securities; provided that if, as a result of
     such Pro Rata redemption, Clearing Agency Participants would hold
     fractional interests in the Preferred Securities, the Depository will
     adjust the amount of the interest of each Clearing Agency Participant to be
     redeemed to avoid such fractional interests.

          (iii)  If Securities are to be redeemed and the Trust gives a
     Redemption/Distribution Notice, which notice may only be issued if the
     Debentures are redeemed as set out in this Section 4 (which notice will be
     irrevocable), then (A) while the Preferred Securities are in book entry
     only form, with respect to the Preferred Securities, by 12:00 noon, New
     York City time, on the redemption date, provided that the Debenture Issuer
     has paid the Property Trustee a sufficient amount of cash in connection
     with the related redemption or maturity of the Debentures, the Property
     Trustee will deposit irrevocably with the Depository or its nominee (or
     successor Clearing Agency or its nominee) funds sufficient to pay the
     applicable Redemption Price with respect to the Preferred Securities and
     will give the Depository irrevocable instructions and authority to pay the
     Redemption Price to the Holders of the Preferred Securities, and (B) if the
     Preferred Securities are issued in definitive form, with respect to the
     Preferred Securities, and with respect to the Common Securities, provided
     that the Debenture Issuer has paid the Property Trustee a sufficient amount
     of cash in connection with the related redemption or maturity of the
     Debentures, the Property Trustee will pay the relevant Redemption Price to
     the Holders of such Securities by check mailed to the address of the
     relevant Holder appearing on the books and records of the Trust on the
     redemption date.  If a Redemption/Distribution Notice shall have been given
     and funds deposited as required, if applicable, then immediately prior to
     the close of business on the date of such deposit, or on the redemption
     date, as applicable, all rights of Holders of such Securities so called for
     redemption will cease, except the right of the Holders of such Securities
     to receive the Redemption Price, but without interest on such Redemption
     Price.  Neither the Regular Trustees nor the Trust shall be required to
     register or cause to be registered the transfer of any Securities which
     have been so called for redemption.  If any date fixed for redemption of
     Securities is not a Business Day, then payment of the Redemption Price
     payable on such date will be made on the next succeeding day that is a
     Business Day (and without any interest or other payment in respect of any
     such delay)

                                     - 7 -
<PAGE>
 
     except that, if such Business Day falls in the next calendar year, such
     payment will be made on the immediately preceding Business Day, in each
     case with the same force and effect as if made on such date fixed for
     redemption.  If payment of the Redemption Price in respect of Securities is
     improperly withheld or refused and not paid either by the Property Trustee
     or by the Sponsor as guarantor pursuant to the relevant Securities
     Guarantee, Distributions on such Securities will continue to accrue, from
     the original redemption date to the actual date of payment, in which case
     the actual payment date will be considered the date fixed for redemption
     for purposes of calculating the Redemption Price.

          (iv)  Redemption/Distribution Notices shall be sent to (A) in respect
     of the Preferred Securities, the Depository or its nominee (or any
     successor Clearing Agency or its nominee) if Global Certificates have been
     issued or if Definitive Preferred Security Certificates have been issued,
     to the Holders thereof, and (B) in respect of the Common Securities, to the
     Holders thereof.

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

          5.  Voting Rights - Preferred Securities.  (a)  Except as provided
under Sections 5(b) and 7 and as otherwise required by law and the Declaration,
the Holders of the Preferred Securities will have no voting rights.

          (b) The Holders of a Majority in liquidation amount of the Preferred
Securities, voting separately as a class, may direct the time, method and place
of conducting any proceeding for any remedy available to the Property Trustee,
or exercising any trust or power conferred upon the Property Trustee under the
Declaration, including (i) directing the time, method and place of conducting
any proceeding for any remedy available to the Debenture Trustee, or executing
any trust or power conferred on the Debenture Trustee with respect to the
Debentures, (ii) waive any past default and its consequences that is waivable
under the Indenture, (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable, or (iv)
consent to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, provided, however, that where
a consent under the Indenture would require the consent of greater than a
majority of the Holders in principal amount of Debentures affected thereby (a
"Super Majority"), the Property Trustee may only give such consent at the
direction of the Holders of at

                                     - 8 -
<PAGE>
 
least the proportion in liquidation amount of the Preferred Securities which the
relevant Super Majority represents of the aggregate principal amount of the
Debentures.  The Property Trustee shall not take any action in accordance with
the directions of the Holders of the Preferred Securities under this paragraph
unless the Property Trustee has obtained an opinion of independent tax counsel
to the effect that, for the purposes of United States federal income tax, the
Trust will not be classified as other than a grantor trust on account of such
action and that each Holder of the Securities will be treated as owning an
undivided beneficial interest in the Debentures on account of such action.  If
the Property Trustee fails to enforce its rights under the Declaration, any
Holder of Preferred Securities may, after a period of 30 days has elapsed from
such Holder's written request to the Property Trustee to enforce such rights,
institute a legal proceeding directly against any Person to enforce the Property
Trustee's rights under the Declaration, without first instituting a legal
proceeding against the Property Trustee or any other Person.

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

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

          Notwithstanding that Holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Sponsor, or by any entity directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Sponsor shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

          6.  Voting Rights - Common Securities.  (a)  Except as provided under
Section 6(b) and (c) and as otherwise required by

                                     - 9 -
<PAGE>
 
law and the Declaration, the Holders of the Common Securities will have no
voting rights.

          (b)  The Holders of the Common Securities are entitled, in accordance
with Article V of the Declaration, to vote to appoint, remove or replace any
Trustee or to increase or decrease the number of Trustees.

          (c) Only after the Event of Default with respect to the Preferred
Securities has been cured, waived or otherwise eliminated, the Holders of a
Majority in liquidation amount of the Common Securities, voting separately as a
class, may direct the time, method and place of conducting any proceeding for
any remedy available to the Property Trustee, or exercising any trust or power
conferred upon the Property Trustee under the Declaration, including (i)
directing the time, method and place of conducting any proceeding for any remedy
available to the Debenture Trustee, or executing any trust or power conferred on
the Debenture Trustee with respect to the Debentures, (ii) waive any past
default and its consequences that is waivable under Section 6.06 of the
Indenture, (iii) exercise any right to rescind or annul a declaration that the
principal of all the Debentures shall be due and payable, or (iv) consent to any
amendment, modification or termination of the Indenture or the Debentures, where
such consent shall be required, provided, however, that where a consent under
the Indenture would require the consent of a Super Majority, the Property
Trustee may only give such consent at the direction of the Holders of at least
the proportion in liquidation amount of the Common Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures.
The Property Trustee shall not take any action in accordance with the directions
of the Holders of the Common Securities under this paragraph unless the Property
Trustee has obtained an opinion of tax counsel to the effect that, for the
purposes of United States federal income tax, the Trust will not be classified
as an association taxable as a corporation or a partnership and that each Holder
of the Securities will be treated as owning an undivided beneficial interest in
the Debentures on account of such action.  If the Property Trustee fails to
enforce its rights under the Declaration, any Holder of Common Securities may,
after a period of 30 days has elapsed from such Holder's written request to the
Property Trustee to enforce such rights, institute a legal proceeding directly
against any Person to enforce the Property Trustee's rights under the
Declaration, without first instituting a legal proceeding against the Property
Trustee or any other Person.

          Any approval or direction of Holders of Common Securities may be given
at a separate meeting of Holders of Common Securities convened for such purpose,
at a meeting of all of the Holders of Securities in the Trust or pursuant to
written consent.  The Regular Trustees will cause a notice of any meeting

                                     - 10 -
<PAGE>
 
at which Holders of Common Securities are entitled to vote, or of any matter
upon which action by written consent of such Holders is to be taken, to be
mailed to each Holder of record of Common Securities.  Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

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

          7.  Amendments.  If any proposed amendment to the Declaration provides
for, or the Regular Trustees otherwise propose to effect, (i) any action that
would adversely affect the powers, preferences or special rights of the Trust
Securities, whether by way of amendment to the Declaration or otherwise, or (ii)
the dissolution, winding-up or termination of the Trust, other than as described
in Section 8.1 of the Declaration, then the Holders of outstanding Trust
Securities, as a single class, will be entitled to vote on such amendment or
proposal (but not on any other amendment or proposal) and such amendment or
proposal shall not be effective except with the approval of the Holders of at
least 66-2/3 in liquidation amount of the Trust Securities affected thereby,
provided that a reduction of the aggregate liquidation amount or the
distribution rate, or a change in the payment dates or maturities of the
Preferred Securities shall not be permitted without the consent of each holder
of the Preferred Securities.  In the event any amendment or proposal referred to
in clause (i) above would adversely affect only the Preferred Securities or the
Common Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of 66-2/3 in liquidation amount of such class of Trust
Securities.

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

                                     - 11 -
<PAGE>
 
all amounts owed to the Holders of the Preferred Securities, to each Holder of
Common Securities pro rata according to the aggregate liquidation amount of
Common Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Common Securities outstanding.

          9.  Ranking.  The Preferred Securities rank pari passu and payment
thereon shall be made Pro Rata with the Common Securities except that when an
Event of Default occurs and is continuing, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Preferred Securities.

          10.  Listing.  The Regular Trustees shall use their best efforts to
cause the Preferred Securities to be listed for quotation on the New York Stock
Exchange, Inc.

          11.  Acceptance of Securities Guarantees and Indenture.  Each Holder
of Preferred Securities and Common Securities, by the acceptance thereof, agrees
to the provisions of the Preferred Securities Guarantee and the Common
Securities Guarantee, respectively, including the subordination provisions
therein and to the provisions therein and to the provisions of the Indenture.

          12.  No Preemptive Rights.  The Holders of the Securities shall have
no preemptive rights to subscribe for any additional Securities.

          13.  Miscellaneous.  These terms constitute a part of the Declaration.

          The Sponsor will provide a copy of the Declaration and the Preferred
Securities Guarantee to a Holder without charge on written request to the
Sponsor at its principal place of business.

                     COMMON SECURITIES GUARANTEE AGREEMENT


          THIS COMMON SECURITIES GUARANTEE AGREEMENT (this "Guarantee
Agreement"), dated as of ________, 1995, is executed and delivered by
COMMONWEALTH EDISON COMPANY, an Illinois corporation (the "Guarantor"), for the
benefit of the Holders (as defined herein) from time to time of the Common
Securities (as defined in the Declaration) of ComEd Financing I, a Delaware
business trust (the "Issuer").


                              W I T N E S S E T H:

          WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of _______, 1995, among the Trustees of the Issuer
named therein, the Guarantor as Sponsor and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer is
issuing on the date hereof $[          ] aggregate stated liquidation amount of
Common Securities designated the ________% Trust Originated Common Securities
(the "Common Securities"); and

          WHEREAS, as incentive for the Holders to purchase the Common
Securities, the Guarantor desires irrevocably and unconditionally to agree, to
the extent set forth in this Guarantee Agreement, to pay to the Holders of the
Common Securities the Guarantee Payments (as defined herein) and to make certain
other payments on the terms and conditions set forth herein; and

          WHEREAS, the Guarantor is also executing and delivering a guarantee
agreement (the "Preferred Securities Guarantee") in substantially identical
terms to this Guarantee Agreement for the benefit of the holders of the
Preferred Securities, except that if an Event of Default (as defined in the
Indenture), has occurred and is continuing, the rights of Holders of the Common
Securities to receive Guarantee Payments under this Guarantee Agreement are
subordinated to the rights of holders of Preferred Securities to receive
guarantee payments under the Preferred Securities Guarantee Agreement;

          NOW, THEREFORE, in consideration of the purchase by each Holder of
Common Securities, which purchase the Guarantor hereby agrees shall benefit the
Guarantor, the Guarantor executes and delivers this Guarantee Agreement for the
benefit of the Holders.


                                   ARTICLE I
                         DEFINITIONS AND INTERPRETATION

          Section 1.1. Definitions.  In this Guarantee Agreement, unless the
context otherwise requires, the terms set forth below shall have the following
meanings.  Terms defined in the Declara-
<PAGE>
 
tion as at the date of execution of this Guarantee Agreement have the same
meaning when used in this Guarantee Agreement unless otherwise defined in this
Guarantee Agreement.

          "Guarantee Payments" shall mean the following payments or
     distributions, without duplication, with respect to the Common Securities,
     to the extent not paid or made by the Issuer:  (i) any accrued and unpaid
     Distributions that are required to be paid on such Common Securities to the
     extent the Issuer shall have funds available therefor, (ii) the redemption
     price, including all accrued and unpaid Distributions to the date of
     redemption (the "Redemption Price") to the extent the Issuer has funds
     available therefor, with respect to any Common Securities called for
     redemption by the Issuer, and (iii) upon a voluntary or involuntary
     dissolution, winding-up or termination of the Issuer (other than in
     connection with the distribution of Debentures to the Holders in exchange
     for Common Securities as provided in the Declaration), the lesser of (a)
     the aggregate of the liquidation amount and all accrued and unpaid
     Distributions on the Common Securities to the date of payment, and (b) the
     amount of assets of the Issuer remaining available for distribution to
     Holders in liquidation of the Issuer (in either case, the "Liquidation
     Distribution").  If an Event of Default (as defined in the Indenture) has
     occurred and is continuing, the rights of Holders of the Preferred
     Securities to receive Guarantee Payments under this Guarantee Agreement are
     subordinated to the rights of holders of Preferred Securities to receive
     guarantee payments under the Preferred Securities Guarantee.

     of the Issuer, of any Common Securities.

The word "or" is not exclusive, and the words "herein," "hereof" and "hereunder"
refer to this Guarantee Agreement as a whole.  The headings to the Articles and

agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim that the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by

notice of acceptance of this Guarantee Agreement and of any liability to which
it applies or may apply, presentment, demand for payment, any right to require a

against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice
of redemption and all other notices and demands.

          Section 2.3.  Obligations Not Affected.  The obligations, covenants,
agreements and duties of the Guarantor under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

          (a)  the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Common Securities to
     be performed or observed by the Issuer;

          (b)  the extension of time for the payment by the Issuer of all or any
     portion of the Distributions, Redemption Price, Liquidation Distribution or
     any other sums payable under the terms of the Common Securities or the
     extension of time for the performance of any other obligation under,
     arising out of, or in connection with, the Common Securities (other than an
     extension of time for payment of Distributions, Redemption Price,
     Liquidation Distribution or other sum payable that results from the
     extension of any interest payment period on the Debentures or any extension
     of the maturity date of the Debentures permitted by the Indenture);

          (c) any failure, omission, delay or lack of diligence on the part of
     the Holders to enforce, assert or exercise any right, privilege, power or
     remedy conferred on the Holders pursuant to the terms of the Common

          (d) the voluntary or involuntary liquidation, dissolution, sale of
     any collateral, receivership, insolvency, bankruptcy, assignment for the

     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

          (e) any invalidity of, or defect or deficiency in, the Common
     Securities;

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

          (g) any other circumstance whatsoever that might otherwise constitute
     a legal or equitable discharge or defense of a guarantor, it being the
     intent of this Section 2.3 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.

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

          Section 2.4.   Rights of Holders.  The Guarantor expressly
acknowledges that any Holder of Common Securities may institute a legal
proceeding directly against the Guarantor to enforce its rights under this
Guarantee Agreement, without first instituting a legal proceeding against the
Issuer or any other Person.

          Section 2.5.  Guarantee of Payment.  This Guarantee Agreement creates
a guarantee of payment and not of collection.

          Section 2.6.   Subrogation.  The Guarantor shall be subrogated to all
(if any) rights of the Holders of Common Securities against the Issuer in
respect of any amounts paid to such Holders by the Guarantor under this
Guarantee Agreement; provided, however, that the Guarantor shall not (except to
the extent required by mandatory provisions of law) be entitled to enforce or
exercise any rights 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
Guarantee Agreement, if, at the time of any such payment, any amounts are due
and unpaid under this Guarantee Agreement.  If any amount shall be paid to the
Guarantor in violation of the preceding sentence, the Guarantor agrees to hold
such amount in trust for the Holders and to pay over such amount to the Holders.

          Section 2.7.   Independent Obligations.  The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Issuer
with respect to the Common Securities, and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms

                                      -5-

unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to all other liabilities of the Guarantor, (ii) pari passu
with the most senior preferred or preference stock now or hereafter issued by
the Guarantor and with any guarantee now or hereafter entered into by the
Guarantor in respect of any preferred or preference stock of any Affiliate of
the Guarantor, and (iii) senior to the Guarantor's common stock.


                                   ARTICLE IV

          Section 4.1.   Termination.  This Guarantee Agreement shall terminate
(i) upon full payment of the Redemption Price of all Common Securities, (ii)
upon the distribution of the Debentures to the Holders of all of the Common
Securities or (iii) upon full payment of the amounts payable in accordance with
the Declaration upon liquidation of the Issuer.  Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated, as
the case may be, if at any time any Holder of Common Securities must restore
payment of any sums paid under the Common Securities or under this Guarantee
Agreement.

the Company, and may have such letters, numbers or other marks of identification
or designation and such legends or endorsements printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Indenture, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which Debt Securities of that series may be
listed, or to conform to usage.

          SECTION 2.03.  Denominations; Provisions for Payment.  The Debt
Securities shall be issuable as registered Debt Securities and in the
denominations of twenty-five U.S. dollars ($25) or any integral multiple
thereof, subject to Section 2.01(11). The Debt Securities of a particular series
shall bear interest payable on the dates and at the rate specified with respect
to that series.  The principal of and the interest on the Debt Securities of any
series, as well as any premium thereon in case of redemption thereof prior to
maturity, shall be payable in the coin or currency of the United States of
America that at the time is legal tender for public and private debt, at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City and State of New York.  Each Debt Security shall be dated
the date of its authentication.  Interest on the Debt Securities shall be

                                      -11-
<PAGE>
 
computed on the basis of a 360-day year composed of twelve 30-day months.

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

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

          (1)  The Company may make payment of any Defaulted Interest on Debt
     Securities to the Persons in whose names such Debt Securities (or their
     respective Predecessor Debt Securities) are registered at the close of
     business on a special record date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner:  the Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each such Debt Security and the date of the proposed payment,
     and at the same time the Company shall deposit with the Trustee an amount
     of money equal to the aggregate amount proposed to be paid in respect of
     such Defaulted Interest or shall make arrangements satisfactory to the
     Trustee for such deposit prior to the date of the proposed payment, such
     money when deposited to be held in trust for the benefit of the Persons
     entitled to such Defaulted Interest as in this clause provided.  Thereupon
     the Trustee shall fix a special record date for the payment of such
     Defaulted Interest which shall not be more than 15 nor less than 10 days
     prior to the date of the proposed payment and not less than 10 days after
     the receipt by the Trustee of the notice of the proposed payment.  The
     Trustee shall promptly notify the Company of such special record date and,
     in the name and at the expense of the Company, shall cause notice of the
     proposed payment of such Defaulted Interest and the special record date
     therefor to be mailed, first class postage prepaid, to each Securityholder
     at his or her address as it appears in the Security Register (as
     hereinafter defined), not less than 10 days prior to such special record

                                      -12-
<PAGE>
 
     date.  Notice of the proposed payment of such Defaulted Interest and the
     special record date therefor having been mailed as aforesaid, such
     Defaulted Interest shall be paid to the Persons in whose names such Debt
     Securities (or their respective Predecessor Debt Securities) are registered
     on such special record date and shall be no longer payable pursuant to the
     following clause (2).

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

          Unless otherwise set forth in a Board Resolution of the Company or one
or more indentures supplemental hereto establishing the terms of any series of
Debt Securities pursuant to Section 2.01 hereof, the term "regular record date"
as used in this Section with respect to a series of Debt Securities with respect
to any Interest Payment Date for such series shall mean either the fifteenth day
of the month immediately preceding the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if such
Interest Payment Date is the first day of a month, or the last day of the month
immediately preceding the month in which an Interest Payment Date established
for such series pursuant to Section 2.01 hereof shall occur, if such Interest
Payment Date is the fifteenth day of a month, whether or not such date is a
Business Day.

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

          SECTION 2.04.  Execution and Authentication.  The Debt Securities
shall be signed on behalf of the Company by its President or one of its Vice
Presidents, under its corporate seal attested by its Secretary or one of its
Assistant Secretaries.  Signatures may be in the form of a manual or facsimile
signature.  The Company may use the facsimile signature of any Person who shall
have been a President or Vice President thereof, or of any Person who shall have
been a Secretary or Assistant Secretary thereof, notwithstanding the fact that
at the time the Debt Securities shall be authenticated and delivered or disposed
of such Person shall have ceased to be the President or a Vice President, or the
Secretary or an Assistant Secretary, of the Company.  The seal of the Company
may be in the form of a facsimile of such seal and may be impressed, affixed,
imprinted or otherwise reproduced on the
 

                                      -13-
<PAGE>
 
Debt Securities.  The Debt Securities may contain such notations, legends or
endorsements required by law, stock exchange rule or usage.  Each Debt Security
shall be dated the date of its authentication by the Trustee.

          A Debt Security shall not be valid until authenticated manually by an
authorized signatory of the Trustee, or by an Authenticating Agent.  Such
signature shall be conclusive evidence that the Debt Security so authenticated
has been duly authenticated and delivered hereunder and that the holder is
entitled to the benefits of this Indenture.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debt Securities of any series executed
by the Company to the Trustee for authentication, together with a written order
of the Company for the authentication and delivery of such Debt Securities,
signed by its President or any Vice President and its Treasurer or any Assistant
Treasurer, and the Trustee in accordance with such written order shall
authenticate and deliver such Debt Securities.

          In authenticating such Debt Securities and accepting the additional
responsibilities under this Indenture in relation to such Debt Securities, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

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

          SECTION 2.05.  Registration of Transfer and Exchange.   (a)  Debt
Securities of any series may be exchanged upon presentation thereof at the
office or agency of the Company designated for such purpose in the Borough of
Manhattan, the City and State of New York, for other Debt Securities of such
series of authorized denominations, and for a like aggregate principal amount,
upon payment of a sum sufficient to cover any tax or other governmental charge
in relation thereto, all as provided in this Section.  In respect of any Debt
Securities so surrendered for exchange, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in exchange therefor
the Debt Security or Debt Securities of the same series that the Securityholder
making the exchange shall be entitled to receive, bearing numbers not
contemporaneously outstanding.

          (b)  The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in the Borough of
 

                                      -14-
<PAGE>
 
Manhattan, the City and State of New York, or such other location designated by
the Company a register or registers (herein referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall register the Debt Securities and the transfers of Debt
Securities as in this Article provided and which at all reasonable times shall
be open for inspection by the Trustee.  The registrar for the purpose of
registering Securities and transfer of Securities as herein provided shall be
appointed as authorized by Board Resolution (the "Security Registrar").

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

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

          (c)  No service charge shall be made for any exchange or registration
of transfer of Debt Securities, or issue of new Debt Securities in case of
partial redemption of any series, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04
not involving any transfer.

          (d)  The Company shall not be required (i) to issue, exchange or
register the transfer of any Debt Securities during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of less than all the Outstanding Debt Securities of the same series
and ending at the close of business on the day of such mailing, nor (ii) to
register the transfer of or exchange any Debt Securities of any series or
portions thereof called for redemption.  The provisions of this Section 2.05
are, with respect to any Global Security, subject to Section 2.11 hereof.

          SECTION 2.06.  Temporary Securities.  Pending the preparation of
definitive Debt Securities of any series, the Company may execute, and the
Trustee shall authenticate and deliver, temporary Debt Securities (printed,
lithographed or typewritten) of any authorized denomination.  Such temporary
Debt Securities shall be substantially in the form of the definitive Debt
Securities in lieu of which they are issued, but with such
 

                                      -15-
<PAGE>
 
omissions, insertions and variations as may be appropriate for temporary Debt
Securities, all as may be determined by the Company.  Every temporary Debt
Security of any series shall be executed by the Company and be authenticated by
the Trustee upon the same conditions and in substantially the same manner, and
with like effect, as the definitive Debt Securities of such series.  Without
unnecessary delay the Company will execute and will furnish definitive Debt
Securities of such series and thereupon any or all temporary Debt Securities of
such series may be surrendered in exchange therefor (without charge to the
holders), at the office or agency of the Company designated for the purpose in
the Borough of Manhattan, the City and State of New York, and the Trustee shall
authenticate and such office or agency shall deliver in exchange for such
temporary Debt Securities an equal aggregate principal amount of definitive Debt
Securities of such series, unless the Company advises the Trustee to the effect
that definitive Debt Securities need not be executed and furnished until further
notice from the Company.  Until so exchanged, the temporary Debt Securities of
such series shall be entitled to the same benefits under this Indenture as
definitive Debt Securities of such series authenticated and delivered hereunder.

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

                                      -16-
<PAGE>
 
Company and the Trustee of the destruction, loss or theft of such Debt Security
and of the ownership thereof.

          Every replacement Debt Security issued pursuant to the provisions of
this Section shall constitute an additional contractual obligation of the
Company, whether or not the mutilated, destroyed, lost or stolen Debt Security
shall be found at any time, or be enforceable by anyone, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and
all other Debt Securities of the same series duly issued hereunder.  All Debt
Securities shall be held and owned upon the express condition that the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Debt Securities, and shall preclude (to the
extent lawful) any and all other rights or remedies, notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

          SECTION 2.08.  Cancellation.  All Debt Securities surrendered for the
purpose of payment, redemption, exchange or registration of transfer shall, if
surrendered to the Company or any paying agent, be delivered to the Trustee for
cancellation, or, if surrendered to the Trustee, shall be cancelled by it, and
no Debt Securities shall be issued in lieu thereof except as expressly required
or permitted by any of the provisions of this Indenture.  On request of the
Company at the time of such surrender, the Trustee shall deliver to the Company
canceled Debt Securities held by the Trustee.  In the absence of such request
the Trustee may dispose of canceled Debt Securities in accordance with its
standard procedures and deliver a certificate of disposition to the Company.  If
the Company shall otherwise acquire any of the Debt Securities, however, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Debt Securities unless and until the same are
delivered to the Trustee for cancellation.

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

          SECTION 2.10.  Authenticating Agent.  So long as any of the Debt
Securities of any series remain Outstanding, there may be an Authenticating
Agent for any or all such series of Debt Securities which the Trustee shall have
the right to appoint.  Said
 

                                      -17-
<PAGE>
 
Authenticating Agent shall be authorized to act on behalf of the Trustee to
authenticate Debt Securities of such series issued upon exchange, transfer or
partial redemption thereof, and Debt Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  All references in
this Indenture to the authentication of Debt Securities by the Trustee shall be
deemed to include authentication by an Authenticating Agent for such series.
Each Authenticating Agent shall be acceptable to the Company and shall be a
corporation that has a combined capital and surplus, as most recently reported
or determined by it, sufficient under the laws of any jurisdiction under which
it is organized or in which it is doing business to conduct a trust business,
and that is otherwise authorized under such laws to conduct such business and is
subject to supervision or examination by federal or state authorities.  If at
any time any Authenticating Agent shall cease to be eligible in accordance with
these provisions, it shall resign immediately.

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

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

          (b)  Notwithstanding the provisions of Section 2.05, the Global
Security or Securities of a series may be transferred, in whole but not in part
and in the manner provided in Section 2.05, only to another nominee of the
Depositary for such series, or to a
 

                                      -18-
<PAGE>
 
successor Depositary for such series selected or approved by the Company or to a
nominee of such successor Depositary.

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


                                  ARTICLE III
           REDEMPTION OF DEBT SECURITIES AND SINKING FUND PROVISIONS

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

          SECTION 3.02.  Notice of Redemption.  (a)  In case the Company shall
desire to exercise such right to redeem all or, as
 

                                      -19-
<PAGE>
 
the case may be, a portion of the Debt Securities of any series in accordance
with the right reserved so to do, the Company shall, or shall cause the Trustee
to, give notice of such redemption to holders of the Debt Securities of such
series to be redeemed by mailing, first class postage prepaid, a notice of such
redemption not less than 30 days and not more than 90 days before the date fixed
for redemption of that series to such holders at their last addresses as they
shall appear upon the Security Register unless a shorter period is specified in
the Debt Securities to be redeemed.  Any notice that is mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the registered holder receives the notice.  In any case, failure duly to
give such notice to the holder of any Debt Security of any series designated for
redemption in whole or in part, or any defect in the notice, shall not affect
the validity of the proceedings for the redemption of any other Debt Securities
of such series or any other series.  In the case of any redemption of Debt
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Debt Securities or elsewhere in this Indenture,
the Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with any such restriction.

          Each such notice of redemption shall specify the date fixed for
redemption and the redemption price at which Debt Securities of that series are
to be redeemed, and shall state that payment of the redemption price of such
Debt Securities to be redeemed will be made at the office or agency of the
Company in the Borough of Manhattan, the City and State of New York, upon
presentation and surrender of such Debt Securities, that interest accrued to the
date fixed for redemption will be paid as specified in said notice, that from
and after said date interest will cease to accrue and that the redemption is for
a sinking fund, if such is the case.  If less than all the Debt Securities of a
series are to be redeemed, the notice to the holders of Debt Securities of that
series to be redeemed in whole or in part shall specify the particular Debt
Securities to be so redeemed.  In case any Debt Security is to be redeemed in
part only, the notice that relates to such Debt Security shall state the portion
of the principal amount thereof to be redeemed, and shall state that on and
after the redemption date, upon surrender of such Debt Security, a new Debt
Security or Debt Securities of such series in principal amount equal to the
unredeemed portion thereof will be issued.

          (b)  If less than all the Debt Securities of a series are to be
redeemed, the Company shall give the Trustee at least 45 days' notice in advance
of the date fixed for redemption as to the aggregate principal amount of Debt
Securities of the series to be redeemed, and thereupon the Trustee shall select,
by lot or in such other manner as it shall deem appropriate and fair in its
discretion and that may provide for the selection of a portion or portions
(equal to twenty-five U.S. dollars ($25) or any integral multiple thereof) of
the principal amount of such Debt Securities of a denomination larger than $25,
the Debt Securities to be

                                      -20-
<PAGE>
 
redeemed and shall thereafter promptly notify the Company in writing of the
numbers of the Debt Securities to be redeemed, in whole or in part.

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

          SECTION 3.03.  Payment Upon Redemption.  (a)  If the giving of notice
of redemption shall have been completed as above provided, the Debt Securities
or portions of Debt Securities of the series to be redeemed specified in such
notice shall become due and payable on the date and at the place stated in such
notice at the applicable redemption price, together with interest accrued to the
date fixed for redemption and interest on such Debt Securities or portions of
Debt Securities shall cease to accrue on and after the date fixed for
redemption, unless the Company shall default in the payment of such redemption
price and accrued interest with respect to any such Debt Security or portion
thereof.  On presentation and surrender of such Debt Securities on or after the
date fixed for redemption at the place of payment specified in the notice, said
Debt Securities shall be paid and redeemed at the applicable redemption price
for such series, together with interest accrued thereon to the date fixed for
redemption (but if the date fixed for redemption is an interest payment date,
the interest installment payable on such date shall be payable to the registered
holder at the close of business on the applicable record date pursuant to
Section 2.03).

          (b)  Upon presentation of any Debt Security of such series that is to
be redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Debt Security is presented shall
deliver to the holder thereof, at the expense of the Company, a new Debt
Security or Debt Securities of the same series, of authorized denominations in
principal amount equal to the unredeemed portion of the Debt Security so
presented.

          SECTION 3.04.  Sinkinq Fund.  The provisions of Sections 3.04, 3.05
and 3.06 shall be applicable to any sinking fund for the retirement of Debt
Securities of a series, except as otherwise

                                      -21-
<PAGE>
 
specified as contemplated by Section 2.01 for Debt Securities of such series.

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

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

          SECTION 3.06.  Redemption of Debt Securities for Sinkinq Fund.  Not
less than 45 days prior to each sinking fund payment date for any series of Debt
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of the series, the portion thereof, if any, that is to be
satisfied by delivering and crediting Debt Securities of that series pursuant to
Section 3.05 and the basis for such credit and will, together with such
Officers' Certificate, deliver to the Trustee any Debt Securities to be so
delivered.  Not less than 30 days before each such sinking fund payment date,
the Trustee shall select the Debt Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 3.02 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 3.02. Such notice having been duly
given, the redemption of such Debt Securities shall be made upon the terms and
in the manner stated in Section 3.03.

                           COVENANTS OF THE COMPANY

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

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

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

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

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

                                      -23-
<PAGE>
 
          (3)  that it will, at any time during the continuance of any failure
     referred to in the preceding paragraph (a)(2) above, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums so held in
     trust by such paying agent; and

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

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

          (c)  Notwithstanding anything in this Section to the contrary, (i) the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Section 11.05, and (ii) the Company may at any time, for the
purpose of obtaining the satisfaction and discharge of this Indenture or for any
other purpose, pay, or direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying agent, such sums to be held by the
Trustee upon the same terms and conditions as those upon which such sums were
held by the Company or such paying agent; and, upon such payment by any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.

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

          SECTION 4.05.  Compliance with Consolidation Provisions.  The Company
will not, while any of the Debt Securities remain Outstanding, consolidate with,
or merge into, or merge into itself, or sell or convey all or substantially all
of its property to any

                                      -24-
<PAGE>
 
other company unless the provisions of Article X hereof are complied with.

          SECTION 4.06.  Limitation on Dividends; Transactions with Affiliates.
(a)  If Debt Securities are issued to a ComEd Trust or a trustee of such trust
in connection with the issuance of Trust Securities by such ComEd Trust and (i)
there shall have occurred any event that would constitute an Event of Default or
(ii) the Company shall be in default with respect to its payment or any
obligations under the Preferred Securities Guarantee or Common Securities
Guarantee relating to such Trust Securities, then (x) the Company shall not
declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase or make a liquidation payment with respect to, any of its
capital stock, (y) the Company shall not make any payment of interest, principal
or premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees) issued by the Company which rank pari passu with or
junior to such Debt Securities and (z) the Company shall not make guarantee
payments with respect to the foregoing (other than pursuant to the Preferred
Securities Guarantee).

          (b)  If Debt Securities are issued to a ComEd Trust or a trustee of
such trust in connection with the issuance of Trust Securities by such ComEd
Trust and the Company shall have given notice of its election to defer payments
of interest on such Debt Securities by extending the interest payment period as
provided in any indenture supplemental hereto and such period, or any extension
thereof, shall be continuing, then (i) the Company shall not declare or pay any
dividend, or make any distributions with respect to, or redeem, purchase or make
a liquidation payment with respect to, any of its capital stock, (ii) the
Company shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or redeem any debt securities (including guarantees) issued
by the Company which rank pari passu with or junior to such Debt Securities and
(iii) the Company shall not make any guarantee payments with respect to the
foregoing (other than pursuant to the Preferred Securities Guarantee).

          SECTION 4.07.  Covenants as to ComEd Trust.  In the event Debt
Securities are issued and sold to a ComEd Trust in connection with the issuance
of Trust Securities by such trust, for so long as such Trust Securities remain
outstanding, the Company will (i) maintain 100% direct or indirect ownership of
the Common Securities of such trust; provided, however, that any permitted
successor of the Company under the Indenture may succeed to the Company's
ownership of the Common Securities, (ii) not cause, as sponsor of such trust, or
permit, as holder of Common Securities of such trust, the dissolution, winding-
up or termination of such trust, except in connection with a distribution of
Debt Securities as provided in the Declaration and in connection with certain
mergers, consolidations or amalgamations permitted by the Declaration and (iii)
use its reasonable efforts to cause such trust (a) to remain

                                      -25-
<PAGE>
 
a business trust, except in connection with a distribution of Debt Securities,
the redemption of all of the Trust Securities of such ComEd Trust or certain
mergers, consolidations or amalgamations, each as permitted by the Declaration
of such ComEd Trust, and (b) to otherwise continue to be classified for United
States federal income tax purposes as a grantor trust.

          SECTION 4.08.  Corporate Existence  The Company will, subject to the
provisions of Article X, at all times maintain its corporate existence and right
to carry on business and will duly procure all renewals and extensions thereof,
and, to the extent necessary or desirable in the operation of its business, will
use its best efforts to maintain, preserve and renew all of its rights, powers,
privileges and franchises.

names and addresses of the holders of each series of Debt Securities as of such

after the receipt by the Company of any such request, a list of similar form and
content as of a date not more than 15 days prior to the time such list is

accordance with the rules and regulations prescribed from time to time by the
Commission, such of the supplementary and periodic information, documents and
reports that may be required pursuant to Section 13 of the Exchange Act, in
respect of a security listed and registered on a national securities exchange as

                  REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                              ON EVENT OF DEFAULT

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

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

          (2)  the Company defaults in the payment of the principal of (or
     premium, if any, on) any of the Debt Securities of that series as and when
     the same shall become due and payable whether at maturity, upon redemption,
     by declaration or otherwise, or in any payment required by any sinking or
     analogous fund established with respect to that series; provided, however,
     that a valid extension of the maturity of such Debt Securities in
     accordance with the terms of any indenture supplemental hereto shall not
     constitute a default in the payment of principal or premium, if any;

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

          (4)  the Company pursuant to or within the meaning of any Bankruptcy
     Law (i) commences a voluntary case, (ii) consents to the entry of an order
     for relief against it in an involuntary case, (iii) consents to the
     appointment of a Custodian of it or for all or substantially all of its
     property or (iv) makes a general assignment for the benefit of its
     creditors;

                                      -28-
<PAGE>
 
          (5)  a court of competent jurisdiction enters an order under any
     Bankruptcy Law that (i) is for relief against the Company in an involuntary
     case, (ii) appoints a Custodian of the Company for all or substantially all
     of its property, or (iii) orders the liquidation of the Company, and the
     order or decree remains unstayed and in effect for 90 days; or

          (6)  in the event Debt Securities are issued and sold to a ComEd Trust
     or other trust of the Company in connection with the issuance of Trust
     Securities by such trust, such trust shall have voluntarily or
     involuntarily dissolved, wound-up its business or otherwise terminated its
     existence except in connection with (i) the distribution of Debt Securities
     to holders of Trust Securities in liquidation of their interests in such
     trust, (ii) the redemption of all outstanding Trust Securities of such
     trust, and (iii) mergers, consolidations or amalgamations, each as
     permitted by the Declaration of such trust.

          (b)  If an Event of Default described in clauses 1, 2, 3 or 6 of this
Section 6.01 with respect to Debt Securities of any series at the time
outstanding occurs and is continuing, unless the principal of all the Debt
Securities of that series shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debt Securities of that series then Outstanding hereunder, by notice in writing
to the Company (and to the Trustee, if given by such Securityholders), may
declare the principal of all the Debt Securities of that series to be due and
payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, notwithstanding anything contained in this
Indenture or in the Debt Securities of that series or established with respect
to that series pursuant to Section 2.01 to the contrary.  If an Event of Default
specified in clause (4) or (5) of this Section 6.01 occurs or is continuing,
then the principal amount of all the Debt Securities shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholder.

          (c)  At any time after the principal of the Securities of that series
shall have been so declared due and payable, and before any judgment or decree
for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the holders of a majority in aggregate principal amount of
the Securities of that series then Outstanding hereunder, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if: (i) the Company has paid or deposited with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Securities
of that series and the principal of (and premium, if any, on) any and all
Securities of that series that shall have become due otherwise than by
acceleration (with interest upon such principal and premium, if any, and, to the
extent that such payment is enforceable under applicable law, upon

                                      -29-
<PAGE>
 
overdue installments of interest, at the rate per annum expressed in the
Securities of that series to the date of such payment or deposit) and the amount
payable to the Trustee under Section 7.06, and (ii) any and all Events of
Default under the Indenture with respect to such series, other than the
nonpayment of principal on Securities of that series that shall not have become
due by their terms, shall have been remedied or waived as provided in Section
6.06.

          No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

          (d)  In case the Trustee shall have proceeded to enforce any right
with respect to Securities of that series under this Indenture and such
proceedings shall have been discontinued or abandoned because of such rescission
or annulment or for any other reason or shall have been determined adversely to
the Trustee, then and in every such case the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company and the Trustee shall continue as
though no such proceedings had been taken.

          SECTION 6.02.  Collection of Indebtedness and Suits for Enforcement by
Trustee.

          (a)  The Company covenants that (1) in case it shall default in the
payment of any installment of interest on any of the Securities of a series, or
any payment required by any sinking or analogous fund established with respect
to that series as and when the same shall have become due and payable, and such
default shall have continued for a period of 90 days, or (2) in case it shall
default in the payment of the principal of (or premium, if any, on) any of the
Securities of a series when the same shall have become due and payable, whether
upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities of that series,
the whole amount that then shall have become due and payable on all such
Securities for principal (and premium, if any) or interest, or both, as the case
may be, with interest upon the overdue principal (and premium, if any) and (to
the extent that payment of such interest is enforceable under applicable law
and, if the Securities are held by a ComEd Trust, without duplication of any
other amounts paid by such trust in respect thereof) upon overdue installments
of interest at the rate per annum expressed in the Securities of that series;
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection and the amount payable to the Trustee under
Section 7.06.

          (b)  If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as

                                      -30-
<PAGE>
 
trustee of an express trust, shall be entitled and empowered to institute any
action or proceedings at law or in equity for the collection of the sums so due
and unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company or
other obligor upon the Securities of that series and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company or other obligor upon the Securities of that series, wherever
situated.

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

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

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

                                      -31-
<PAGE>
 
or equitable right vested in the Trustee by this Indenture or by law.

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

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

          FIRST:  To the payment of costs and expenses of collection and of all
     amounts payable to the Trustee under Section 7.06;

          SECOND:  To the payment of all Senior Indebtedness of the Company if
     and to the extent required by Article XIV; and

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

          SECTION 6.04.  Limitation on Suits.  No holder of any Security of any
series shall have any right by virtue or by availing of any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon
or under or with respect to this Indenture or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless (i) such holder previously
shall have given to the Trustee written notice of an Event of Default and of the
continuance thereof with respect to the Securities of such series specifying
such Event of Default, as hereinbefore provided; (ii) the holders of not less
than 25% in aggregate principal amount of the Securities of such series then
Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as trustee hereunder; (iii) such
holder or holders shall have offered to the Trustee such reasonable indemnity as
it may require against the costs, expenses and liabilities to be incurred
therein or thereby; and (iv) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity, shall have failed to

                                      -32-
<PAGE>
 
institute any such action, suit or proceeding; and (v) during such 60 day
period, the holders of a majority in principal amount of the Securities of that
series do not give the Trustee a direction inconsistent with the request.

          Notwithstanding anything contained herein to the contrary, any other
provisions of this Indenture, the right of any holder of any Security to
receive payment of the principal of (and premium, if any) and interest on such
Security, as therein provided, on or after the respective due dates expressed
in such Security (or in the case of redemption, on the redemption date), or to
institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without
the consent of such holder, and by accepting a Security hereunder it is
expressly understood, intended and covenanted by the taker and holder of every
Security of such series with every other such taker and holder and the Trustee,
that no one or more holders of Securities of such series shall have any right
in any manner whatsoever by virtue or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of the holders of any
other of such Securities, or to obtain or seek to obtain priority over or
preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Securities of series.  For the protection and
enforcement of the provisions of this Section, each and every Securityholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

          SECTION 6.05.  Rights and Remedies Cumulative; Delay or Omission Not
Waiver.  (a)  Except as otherwise provided in Section 2.07, all powers and
remedies given by this Article to the Trustee or to the Securityholders shall,
to the extent permitted by law, be deemed cumulative and not exclusive of any
other powers and remedies available to the Trustee or the holders of the
Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Securities.

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

          SECTION 6.06.  Control by Securityholders.  The holders of a majority
in aggregate principal amount of the Securities of any series at the time
Outstanding, determined in accordance with

                                      -33-
<PAGE>
 
Section 8.04, shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee with respect to such
series; provided, however, that such direction shall not be in conflict with
any rule of law or with this Indenture or be unduly prejudicial to the rights
of holders of Securities of any other series at the time Outstanding determined
in accordance with Section 8.04. Subject to the provisions of Section 7.01, the
Trustee shall have the right to decline to follow any such direction if the
Trustee in good faith shall, by a Responsible Officer or Officers of the
Trustee, determine that the proceeding so directed would involve the Trustee in
personal liability.  The holders of a majority in aggregate principal amount of
the Securities of any series at the time Outstanding affected thereby,
determined in accordance with Section 8.04, may on behalf of the holders of all
of the Securities of such series waive any past default in the performance of
any of the covenants contained herein or established pursuant to Section 2.01
with respect to such series and its consequences, except (i) a default in the
payment of the principal of, or premium, if any, or interest on, any of the
Securities of that series as and when the same shall become due by the terms of
such Securities otherwise than by acceleration (unless such default has been
cured and a sum sufficient to pay all matured installments of interest and
principal and any premium has been deposited with the Trustee (in accordance
with Section 6.01(c))  or (ii) a default in the covenants contained in Section
4.06(b).  Upon any such waiver, the default covered thereby shall deemed to be
cured for all purposes of this Indenture and the Company, the Trustee and the
holders of the Securities of such series shall be restored to their former
positions and rights hereunder, respectively; but no such waiver shall extend
to any subsequent or other default or impair any right consequent thereon.

          SECTION 6.07.  Undertaking to Pay Costs.  All parties to this
Indenture agree, and each holder of any Securities by such holder's acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted
by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding more than 10% in aggregate principal amount of the
Outstanding Securities of any series, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security of such series, on or after the
respective due dates expressed in such Security or established pursuant to this
Indenture.

                                 ARTICLE VII
                            CONCERNING THE TRUSTEE

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

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

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

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

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

          (2)  the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer or Responsible

                                      -35-
<PAGE>
 
Officers of the Trustee, unless it shall be proved that the Trustee, was
negligent in ascertaining the pertinent facts;

          (3)  the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
the holders of not less than a majority in principal amount of the Debt
Securities of any series at the time Outstanding relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred upon the Trustee under this Indenture
with respect to the Debt Securities of that series; and

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

          SECTION 7.02.  Certain Rights of Trustee.  Except as otherwise
provided in Section 7.01:

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

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

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

          (d)  The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders, pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby; nothing contained herein shall,
however,

                                      -36-
<PAGE>
 
relieve the Trustee of the obligation, upon the occurrence of an Event of
Default with respect to a series of the Debt Securities (that has not been cured
or waived) to exercise with respect to Debt Securities of that series such of
the rights and powers vested in it by this Indenture, and to use the same degree
of care and skill in their exercise, as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs;

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

          (f)  The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Debt
Securities of the particular series affected thereby (determined as provided in
Section 8.04); provided, however, that if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by it
in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to so proceeding.  The reasonable expense
of every such examination shall be paid by the Company or, if paid by the
Trustee, shall be repaid by the Company upon demand;

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

          (h)  Whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate; and

          (i)  The Trustee shall not be required to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers if it shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

          SECTION 7.03.  Trustee Not Responsible for Recitals or Issuance of
Debt Securities.  (a)  The recitals contained herein

                                      -37-
<PAGE>
 
and in the Debt Securities shall be taken as the statements of the Company, and
the Trustee assumes no responsibility for the correctness of the same.

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

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

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

          SECTION 7.05.  Moneys Held in Trust.  Subject to the provisions of
Section 11.05, all moneys received by the Trustee shall, until used or applied
as herein provided, be held in trust for the purposes for which they were
received, but need not be segregated from other funds except to the extent
required by law.  The Trustee shall be under no liability for interest on any
moneys received by it hereunder except such as it may agree with the Company to
pay thereon.

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

                                      -38-
<PAGE>
 
and expenses of defending itself against any claim of liability in the premises.

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

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

          SECTION 7.08.  Qualification; Conflicting Interests.  If the Trustee
has or shall acquire any "conflicting interest" within the meaning of Section
310(b) of the Trust Indenture Act, the Trustee and the Company shall in all
respects comply with the provisions of Section 310(b) of the Trust Indenture
Act.

          SECTION 7.09.  Corporate Trustee Required; Eligibility.  There shall
at all times be a Trustee with respect to the Debt Securities issued hereunder
which shall at all times be a corporation organized and doing business under the
laws of the United States of America or any State or Territory thereof or of the
District of Columbia, or a corporation or other Person permitted to act as
trustee by the Commission, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least fifty million
U.S. dollars ($50,000,000), and subject to supervision or examination by
Federal, State, Territorial or District of Columbia authority.  If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  The Company may not, nor
may any Person directly or indirectly controlling, controlled by, or under
common control with the Company, serve as Trustee.  In case at any

                                      -39-
<PAGE>
 
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section, the Trustee shall resign immediately in the manner and with the
effect specified in Section 7.10.

          SECTION 7.10.  Resignation and Removal; Appointment of Successor.  (a)
The Trustee or any successor hereafter appointed, may at any time resign with
respect to the Debt Securities of one or more series by giving written notice
thereof to the Company and the Guarantor and by transmitting notice of
resignation by mail, first class postage prepaid, to the Securityholders of such
series, as their names and addresses appear upon the Security Register.  Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee with respect to Debt Securities of such series by written
instrument, in duplicate, executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the resigning Trustee and one copy to
the successor trustee.  If no successor trustee shall have been so appointed and
have accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to Debt
Securities of such series, or any Securityholder of that series who has been a
bona fide holder of a Debt Security or Debt Securities for at least six months
may, subject to the provisions of Section 6.08, on behalf of himself and all
others similarly situated, petition any such court for the appointment of a
successor trustee.  Such court may thereupon after such notice, if any, as it
may deem proper and prescribe, appoint a successor trustee.

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

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

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

          (3)  the Trustee shall become incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
     proceeding, or a receiver of the Trustee or of its property shall be
     appointed or consented to, or any public officer shall take charge or
     control of the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation, then, in any such case, the
     Company may remove the Trustee with respect to all Debt Securities and
     appoint a successor trustee by written instrument, in duplicate, executed
     by order of the Board of

                                      -40-
<PAGE>
 
     Directors, one copy of which instrument shall be delivered to the Trustee
     so removed and one copy to the successor trustee, or, subject to the
     provisions of Section 6.08, unless the Trustee's duty to resign is stayed
     as provided herein, any Securityholder who has been a bona fide holder of a
     Debt Security or Debt Securities for at least six months may, on behalf of
     that holder and all others similarly situated, petition any court of
     competent jurisdiction for the removal of the Trustee and the appointment
     of a successor trustee.  Such court may thereupon after such notice, if
     any, as it may deem proper and prescribe, remove the Trustee and appoint a
     successor trustee.

          (c)  The holders of a majority in aggregate principal amount of the
Debt Securities of any series at the time Outstanding may at any time remove the
Trustee with respect to such series by so notifying the Trustee and the Company
and may appoint a successor Trustee for such series with the consent of the
Company.

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

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

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

          (b)  In case of the appointment hereunder of a successor trustee with
respect to the Debt Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor trustee with respect to the Debt
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein

                                      -41-
<PAGE>
 
each successor trustee shall accept such appointment and which (1) shall contain
such provisions as shall be necessary or desirable to transfer and confirm to,
and to vest in, each successor trustee all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debt Securities of that or those
series to which the appointment of such successor trustee relates, (2) shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Debt Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; and upon the
execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein,
such retiring Trustee shall with respect to the Debt Securities of that or those
series to which the appointment of such successor trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, and each such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Debt Securities of that or those
series to which the appointment of such successor trustee relates; but, on
request of the Company or any successor trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor trustee, to the extent
contemplated by such supplemental indenture, the property and money held by such
retiring Trustee hereunder with respect to the Debt Securities of that or those
series to which the appointment of such successor trustee relates.

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

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

          (e)  Upon acceptance of appointment by a successor trustee as provided
in this Section, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Securityholders,
as their names and

                                      -42-
<PAGE>
 
addresses appear upon the Security Register.  If the Company fails to transmit
such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be transmitted at the
expense of the Company.

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

          SECTION 7.13.  Preferential Collection of Claims Against the Company.
The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.


                                 ARTICLE VIII
                        CONCERNING THE SECURITYHOLDERS

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

          If the Company shall solicit from the Securityholders of any series
any request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders (entitled to give such request, demand, authorization,
direction, notice,

                                      -43-
<PAGE>
 
consent, waiver or other action, but the Company shall have no obligation to do
so.  If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other action may be given before or after
the record date, but only the Securityholders of record at the close of business
on the record date shall be deemed to be Securityholders for the purposes of
determining whether Securityholders of the requisite proportion of Outstanding
Debt Securities of that series have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other
action, and for that purpose the Outstanding Debt Securities of that series
shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

          SECTION 8.02.  Proof of Execution by Securityholders.  Subject to the
provisions of Section 7.01, proof of the execution of any instrument by a
Securityholder (such proof will not require notarization) or his agent or proxy
and proof of the holding by any Person of any of the Debt Securities shall be
sufficient if made in the following manner:

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

          (b)  The ownership of Debt Securities shall be proved by the Debt
     Security Register of such Debt Securities or by a certificate of the Debt
     Security Registrar thereof.

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

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

          SECTION 8.04.  Certain Debt Securities Owned by Company Disregarded.
In determining whether the holders of the requisite aggregate principal amount
of Debt Securities of a particular

                                      -44-
<PAGE>
 
series have concurred in any direction, consent waiver under this Indenture,
the Debt Securities of that series that are owned by the Company or any other
obligor on the Debt Securities of that series or by any Person directly or
indirectly controlling or controlled by or under common control with the
Company or any other obligor on the Debt Securities of that series shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only
Debt Securities of such series that the Trustee actually knows are so owned
shall be so disregarded.  The Debt Securities so owned that have been pledged
in good faith may be regarded as outstanding for the purposes of this Section,
if the pledgee shall establish to the satisfaction of the Trustee the pledgee's
right so to act with respect to such Debt Securities and that the pledgee is
not a Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or the Guarantor or any such
other obligor.  In case of a dispute as to such right, any decision by the
Trustee taken upon the advice of counsel shall be full protection to the
Trustee.

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

                                  ARTICLE IX
                           SUPPLEMENTAL INDENTURES

          SECTION 9.01.  Supplemental Indentures Without the Consent of
Securityholders.  In addition to any supplemental indenture otherwise authorized
by this Indenture, the Company and the Guarantor and the Trustee may from time
to time and at any time enter into an indenture or indentures supplemental
hereto (which

                                      -45-
<PAGE>
 
shall conform to the provisions of the Trust Indenture Act as then in effect),
without the consent of the Securityholders, for one or more of the following
purposes:

          (a)  to cure any ambiguity, defect or inconsistency herein or in the
     Debt Securities of any series;

          (b)  to comply with Article X;

          (c)  to provide for uncertificated Debt Securities in addition to or
     in place of certificated Debt Securities;

          (d)  to add to the covenants of the Company for the benefit of the
     holders of all or any series of Debt Securities (and if such covenants are
     to be for the benefit of less than all series of Debt Securities, stating
     that such covenants are expressly being included solely for the benefit of
     such series) or to surrender any right or power herein conferred upon the
     Company;

          (e)  to add to, delete from, or revise the conditions, limitations and
     restrictions on the authorized amount, terms or purposes of issue,
     authentication and delivery of Debt Securities, as herein set forth;

          (f)  to make any change that does not adversely affect the rights of
     any Securityholder in any material respect; or

          (g)  to provide for the issuance of and establish the form and terms
     and conditions of the Debt Securities of any series as provided in Section
     2.01, to establish the form of any certifications required to be furnished
     pursuant to the terms of this Indenture or any series of Debt Securities,
     or to add to the rights of the holders of any series of Debt Securities.

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

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

          SECTION 9.02.  Supplemental Indentures With Consent of
Securityholders.  With the consent (evidenced as provided in Section 8.01) of
the holders of not less than a majority in aggregate principal amount of the
Debt Securities of each series

                                      -46-
<PAGE>
 
affected by such supplemental indenture or indentures at the time Outstanding,
the Company, when authorized by a Board Resolution, and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental
hereto (which shall conform to the provisions of the Trust Indenture Act as then
in effect) for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Indenture or of any supplemental
indenture or of modifying in any manner not covered by Section 9.01 the rights
of the holders of the Debt Securities of such series under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the holders of each Debt Security then Outstanding and affected
thereby, (i) extend the fixed maturity of any Debt Securities of any series, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Debt Security so affected or
(ii) reduce the aforesaid percentage of Debt Securities, the holders of which
are required to consent to any such supplemental indenture.

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

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

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

of that series then outstanding.

          SECTION 9.05.  Execution of Supplemental Indentures.  Upon the request
of the Company, accompanied by a Board Resolution authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of
evidence of the consent of Securityholders required to consent thereto as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion but shall not be obligated to enter into
such supplemental indenture.  The Trustee, subject to the provisions of Section
7.01, may receive an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article is authorized or
permitted by, and conforms to, the terms of this Article and that it is proper
for the Trustee under the provisions of this Article to join in the execution
thereof.

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

Company shall have been merged, or by the entity which shall have acquired such
property.

punctual performance of all of the covenants and conditions of this Indenture or
established with respect to each series of the Debt Securities pursuant to

successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named as the Company herein.

transfer or other disposition, such changes in phraseology and form (but not in
substance) may be made in the Debt Securities thereafter to be issued as may be

          SECTION 11.01.  Satisfaction and Discharge of Indenture.  If at any
time: (a) the Company shall have delivered to the Trustee for cancellation all
Debt Securities of a series theretofore authenticated (other than any Debt
Securities that shall have been destroyed, lost or stolen and that shall have
been replaced or paid as provided in Section 2.07) and Debt Securities for whose
payment

                                      -49-
<PAGE>
 
money or Governmental Obligations have theretofore been deposited in trust or
segregated and held in trust by the Company or the Guarantor (and thereupon
repaid to the Company or discharged from such trust, as provided in Section
11.05); or (b) all such Debt Securities of a particular series not theretofore
delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year or are to be called
for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption, and the Company shall deposit or cause
to be deposited with the Trustee as trust funds the entire amount in moneys or
Governmental Obligations or a combination thereof, sufficient in the opinion of
a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay at maturity or
upon redemption all Debt Securities of that series not theretofore delivered to
the Trustee for cancellation, including principal (and premium, if any) and
interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to be
paid all other sums payable hereunder with respect to such series by the
Company; then if the Company has delivered to the Trustee an Opinion of Counsel
based on the fact that (x) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (y) since the date
hereof, there has been a change in the applicable United States federal income
tax law, in either case to the effect that, and such opinion shall confirm that,
the holders of the Debt Securities of such series will not recognize income,
gain or loss for United States federal income tax purposes as a result of such
deposit, defeasance and discharge and will be subject to United States federal
income tax on the same amount and in the same manner and at the same times, as
would have been the case if such deposit, defeasance and discharge had not
occurred, this Indenture shall thereupon cease to be of further effect with
respect to such series except for the provisions of Sections 2.03, 2.05, 2.07,
4.01, 4.02, 4.03 and 7.10, that shall survive until the date of maturity or
redemption date, as the case may be, and Sections 7.06 and 11.05, that shall
survive to such date and thereafter, and the Trustee, on demand of the Company
and at the cost and expense of the Company shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture with respect to
such series.

          SECTION 11.02.  Discharge of Obligations.  If at any time all Debt
Securities of a particular series not heretofore delivered to the Trustee for
cancellation or that have not become due and payable as described in Section
11.01 shall have been paid by the Company by depositing irrevocably with the
Trustee as trust funds moneys or an amount of Governmental Obligations
sufficient to pay at maturity or upon redemption all such Debt Securities of
that series not theretofore delivered to the Trustee for cancellation, including
principal (and premium, if any) and interest due or to become due to such date
of maturity or date fixed for redemption, as the case may be, and if the Company
shall also pay or cause to

                                      -50-
<PAGE>
 
be paid all other sums payable hereunder by the Company with respect to such
series, then after the date such moneys or Governmental Obligations, as the case
may be, are deposited with the Trustee then, if the Company has delivered to the
Trustee an Opinion of Counsel based on the fact that (x) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (y) since the date hereof, there has been a change in the applicable
United States federal income tax law, in either case to the effect that, and
such opinion shall confirm that, the holders of the Debt Securities of such
series will not recognize income, gain or loss for United States federal income
tax purposes as a result of such deposit, defeasance and discharge and will be
subject to United States federal income tax on the same amount and in the same
manner and at the same times, as would have been the case if such deposit,
defeasance and discharge had not occurred, the obligations of the Company, under
this Indenture with respect to such series shall cease to be of further effect
except for the provisions of Sections 2.03, 2.05, 2.07, 4.01, 4.02, 4.03, 7.06,
7.10 and 11.05 hereof that shall survive until such Debt Securities shall mature
and be paid. Thereafter, Sections 7.06 and 11.05 shall survive.

          SECTION 11.03.  Deposited Moneys to be Held in Trust.  All moneys or
Governmental Obligations deposited with the Trustee pursuant to Sections 3.11 or
11.02 shall be held in trust and shall be available for payment as due, either
directly or through any paying agent (including the Company acting as its own
paying agent), to the holders of the particular series of Debt Securities for
the payment or redemption of which such moneys or Governmental Obligations have
been deposited with the Trustee.

          SECTION 11.04.  Payment of Moneys Held by Paying Agents.  In
connection with the satisfaction and discharge of this Indenture, all moneys or
Governmental Obligations then held by any paying agent under the provisions of
this Indenture shall, upon demand of the Company, be paid to the Trustee and
thereupon such paying agent shall be released from all further liability with
respect to such moneys or Governmental Obligations.

          SECTION 11.05.  Repayment to Company.  Any moneys or Governmental
Obligations deposited with any paying agent or the Trustee, or then held by the
Company, in trust for payment of principal of or premium or interest on the Debt
Securities of a particular series that are not applied but remain unclaimed by
the holders of such Debt Securities for at least two years after the date upon
which the principal of (and premium, if any) or interest on such Debt Securities
shall have respectively become due and payable, shall be repaid to the Company
on May 31 of each year or (if then held by the Company) shall be discharged from
such trust; and thereupon the paying agent and the Trustee shall be released
from all further liability with respect to such moneys or Governmental
Obligations, and the holder of any of the Debt Securities entitled to receive
such payment shall thereafter, as an

                                      -51-
<PAGE>
 
unsecured general creditor, look only to the Company for the payment thereof.

corporate obligations, and that no such personal liability whatever shall attach

corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debt Securities or implied
therefrom; and that any and all such personal liability of every name and
nature, either at common law or in equity or by constitution or statute, of, and
any and all such rights and claims against, every such incorporator,
stockholder, officer or director as such, because of the creation of the
indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any of the Debt
Securities or implied therefrom, are hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and

          SECTION 13.07.  Compliance Certificates and Opinions.  (a)  Upon any
application or demand by the Company to the Trustee to take any action under any

Officers' Certificate, or established in one or more indentures supplemental to
this Indenture, in any case where the date of maturity of interest or principal
of any Debt Security or the date of redemption of any Debt Security shall not be
a Business Day, then payment of interest or principal (and premium, if any) may
be made on the next succeeding Business Day with the same force and effect as if
made on the nominal date of maturity or redemption, and no interest shall accrue
for the period after such nominal date.

other provisions of this Indenture or of such Debt Securities, but this
Indenture and such Debt Securities shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

          SECTION 13.12.  Assignment.  The Company will have the right at all
times to assign any of its respective rights or obligations under this Indenture
to a direct or indirect wholly-owned Subsidiary of the Company, provided that,
in the event of any such assignment, the Company will remain liable for all such
obligations.  Subject to the foregoing, the Indenture is binding upon and inures
to the benefit of the parties thereto and their respective successors and
assigns.  This Indenture may not otherwise be assigned by the parties thereto.

that, with respect to any Debt Securities held by a ComEd Trust or a trustee of
such trust, if the Property Trustee of such Trust fails to enforce its rights

period of 30 days has elapsed from such holder's written request to such
Property Trustee to enforce such rights, institute legal proceedings directly
against the Company to enforce such Property Trustee's rights under this
Indenture without first instituting any legal proceedings against such Property

                                   ARTICLE II
                        GENERAL TERMS AND CONDITIONS OF
                                   THE NOTES

          Section 2.1.  Designation and Principal Amount.  There is hereby
authorized a series of Debt Securities designated the "__% Subordinated
Deferrable Interest Notes due ________," limited in aggregate principal amount
to $________ million, which amount shall be as set forth in any written order of
the Company for the authentication and delivery of Notes pursuant to Section
2.04 of the Indenture.

          Section 2.2.  Maturity.  The Maturity Date will be _______________.

          Section 2.3.  Form and Payment.  Except as provided in Section 2.4,
the Notes shall be issued in fully registered certificated form without interest
coupons.  Principal and interest on the Notes issued in certificated form will
be payable, the transfer of such Notes will be registrable and such Notes will
be exchangeable for Notes bearing identical terms and provisions at the office
or agency of the Trustee in ________, provided, however, that payment of
interest may be made at the option of the Company by check mailed to the
registered holder at such address as shall appear in the Security Register.
Notwithstanding the foregoing, so long as the registered holder of any Notes is
the Property Trustee, the payment of the principal of and interest (including
Compounded Interest and Additional Interest, if any) on such Notes held by the
Property Trustee will be made at such place and to such account as may be
designated by the Property Trustee.

          Section 2.4.  Global Note.  In connection with a Dissolution Event:

          (a)  the Notes in certificated form may be presented to the Trustee by
     the Property Trustee in exchange for a Global Security in an aggregate
     principal amount equal to the aggregate principal amount of the Notes so
     presented, to be registered in the name of the Depositary, or its nominee,
     and delivered by the Trustee to the Depositary for crediting to the
     accounts of its participants pursuant to the instructions of the Regular
     Trustees.  The Company, upon any such presentation, shall execute a Global
     Security in such aggregate principal amount and deliver the same to the
     Trustee for authentication and delivery in accordance with the Indenture
     and this First Supplemental Indenture.

                                      -4-
<PAGE>
 
     Payments on the Notes issued as a Global security will be made to the
     Depositary; and

          (b)  if any Preferred Securities are held in non book-entry
     certificated form, the Notes in certificated form may be presented to the
     Trustee by the Property Trustee and any Preferred Security Certificate
     which represents Preferred Securities other than Preferred Securities held
     by the Clearing Agency or its nominee ("Non Book-Entry Preferred
     Securities") will be deemed to represent beneficial interests in Notes
     presented to the Trustee by the Property Trustee having an aggregate
     principal amount equal to the aggregate stated liquidation amount of the
     Non Book-Entry Preferred Securities until such Preferred Security
     Certificates are presented to the Security Registrar for transfer or
     reissuance at which time such Preferred Security Certificates will be
     cancelled and a Note, registered in the name of the holder of the Preferred
     Security Certificate or the transferee of the holder of such Preferred
     Security Certificate, as the case may be, with an aggregate principal
     amount equal to the aggregate stated liquidation amount of the Preferred
     Security Certificate cancelled, will be executed by the Company and
     delivered to the Trustee for authentication and delivery in accordance with
     the Indenture and this First Supplemental Indenture.  On issue of such
     Notes, Notes with an equivalent aggregate principal amount that were
     presented by the Property Trustee to the Trustee will be deemed to have
     been cancelled.

          Section 2.5.  Interest.  (a)  Each Note will bear interest at the rate
of ___% per annum (the "Coupon Rate") from the original date of issuance until
the principal thereof becomes due and payable, and on any overdue principal and
(to the extent that payment of such interest is enforceable under applicable
law) on any overdue installment of interest at the Coupon Rate, compounded
quarterly, payable (subject to the provisions of Article IV) quarterly in
arrears on [March 31, June 30, September 30 and December 31] of each year (each,
an "Interest Payment Date", commencing on ________, 1995), to the Person in
whose name such Note or any predecessor Note is registered, at the close of
business on the regular record date for such interest installment, which shall
be the close of business on the Business Day next preceding that Interest
Payment Date.  If pursuant to the provisions of Section 2.11(c) of the Indenture
the Notes are no longer represented by a Global Security, the Company may select
a regular record date for such interest installment which shall be any date at
least fifteen days before an Interest Payment Date.

          (b)  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 Notes is not a Business Day, then payment of
interest

                                      -5-
<PAGE>
 
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.  The amount of interest
payable for any period shorter than a full quarterly period for which interest
is computed, will be computed on the basis of the actual number of days elapsed
in such a 90-day quarter.

          (c)  If at any time while the Property Trustee is the holder of any
Notes, the Trust or the Property Trustee is required to pay any taxes, duties,
assessments or governmental charges of whatever nature (other than withholding
taxes) imposed by the United States, or any other taxing authority, then, in any
case, the Company will pay as additional interest ("Additional Interest") on the
Notes held by the Property Trustee, such additional amounts as shall be required
so that the net amounts received and retained by the Trust and the Property
Trustee after paying such taxes, duties, assessments or other governmental
charges will be equal to the amounts the Trust and the Property Trustee would
have received had no such taxes, duties, assessments or other government charges
been imposed.


                                  ARTICLE III
                            REDEMPTION OF THE NOTES

          Section 3.1.  Special Event Redemption.  If a Tax Event has occurred
and is continuing and:

          (a)  the Company has received a Redemption Tax Opinion; or

          (b)  after receiving a Dissolution Tax Opinion, the Regular Trustees
     shall have been informed by tax counsel rendering the Dissolution Tax
     Opinion that a No Recognition Opinion cannot be delivered to the Trust,

then, notwithstanding Section 3.2(a) but subject to Section 3.2(b), the Company
shall have the right upon not less than 30 days' nor more than 60 days' notice
to the registered holders of the Notes to redeem the Notes, in whole or in part,
for cash within 90 days following the occurrence of such Tax Event (the "90 Day
Period") at a redemption price equal to 100% of the principal amount to be
redeemed plus any accrued and unpaid interest thereon to the date of such
redemption (the "Special Redemption Price"), provided that, if at the time there
is available to the Company the opportunity to eliminate, within the 90 Day
Period, the Tax Event by taking some ministerial action ("Ministerial Action"),
such as filing a form or making an election, or pursuing some other similar
reasonable measure that

                                      -6-
<PAGE>
 
has no adverse effect on the Company, the Trust or the Holders of the Trust
Securities issued by the Trust, the Company shall pursue such Ministerial Action
in lieu of redemption; and provided further, that the Company shall have no
right to redeem the Notes while the Trust is pursuing any Ministerial Action
pursuant to its obligations under the Declaration.  The Special Redemption Price
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 and specifies in the notice of
redemption, provided the Company shall deposit with the Trustee an amount
sufficient to pay the Special Redemption Price by 11:00 a.m. on the date such
Special Redemption Price is to be paid.

          Section 3.2.  Optional Redemption by Company.  (a)   Subject to the
provisions of Article III of the Indenture and to Section 3.2(b), the Company
shall have the right to redeem the Notes, in whole or in part, from time to
time, on or after ________, 2000, at a redemption price equal to 100% of the
principal amount to be redeemed plus any accrued and unpaid interest thereon
to the date of such redemption (the "Optional Redemption Price").  Any
redemption pursuant to this paragraph will be made upon not less than 30 days'
nor more than 60 days' notice to the registered holder of the Notes, at the
Optional Redemption Price.  If the Notes are only partially redeemed pursuant to
this Section 3.2, the Notes 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
Notes are registered as a Global Security, the Depositary shall determine by lot
the principal amount of such Notes held by each Noteholder to be redeemed.  The
Optional Redemption Price 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
and specifies in the notice of redemption, provided the Company shall deposit
with the Trustee an amount sufficient to pay the Optional Redemption Price by
11:00 a.m. on the date such Optional Redemption Price is to be paid.

          (b)  If a partial redemption of the Notes would result in the
delisting of the Preferred Securities issued by the Trust from any national
securities exchange or other organization on which the Preferred Securities are
then listed, the Company shall not be permitted to effect such partial
redemption and may only redeem the Notes in whole.

          Section 3.3.  No Sinking Fund.  The Notes are not entitled to the
benefit of any sinking fund.


                                   ARTICLE IV
                      EXTENSION OF INTEREST PAYMENT PERIOD

          Section 4.1.  Extension of Interest Payment Period.  The Company shall
have the right, at any time and from time to

                                      -7-
<PAGE>
 
time during the term of the Notes, to extend the interest payment period of such
Notes for up to twenty (20) consecutive quarters (the "Extended Interest Payment
Period").  To the extent permitted by applicable law, interest, the payment of
which has been deferred because of the extension of the interest payment period
pursuant to this Section 4.1, will bear interest compounded quarterly at the
Coupon Rate for each quarter of the Extended Interest Payment Period
("Compounded Interest").  At the end of the Extended Interest Payment Period,
the Company shall pay all interest accrued and unpaid on the Notes, including
any Compounded Interest and Additional Interest ("Deferred Interest") which
shall be payable to the holders of the Notes in whose names the Notes are
registered in the Security Register on the first record date after the end of
the Extended Interest Payment Period.  Before the termination of any Extended
Interest Payment Period, the Company may further extend such period, provided
that such period together with all such further extensions thereof shall not
exceed twenty (20) consecutive quarters or extend beyond the maturity of the
Notes.  Upon the termination of any Extended Interest Payment Period and upon
the payment of all Deferred Interest then due, the Company may select a new
Extended Interest Payment Period, subject to the foregoing requirements.  No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof.

          Section 4.2.  Notice of Extension.  (a)  If the Property Trustee is
the only registered holder of the Notes at the time the Company selects an
Extended Interest Payment Period, the Company shall give written notice to both
the Regular Trustees and the Property Trustee of its selection of such Extended
Interest Payment Period one Business Day before the earlier of (i) the next
succeeding date on which Distributions on the Trust Securities issued by the
Trust are payable, or (ii) the date the Trust is required to give notice of the
record or payment date for such Distributions to the New York Stock Exchange or
other applicable self-regulatory organization or to holders of the Preferred
Securities issued by the Trust, but in any event at least one Business Day
before such record date.

          (b)  If the Property Trustee is not the only holder of the Notes at
the time the Company selects an Extended Interest Payment Period, the Company
shall give the holders of the Notes and the Trustee written notice of its
selection of such Extended Interest Payment Period ten (10) Business Days before
the earlier of (i) the next succeeding Interest Payment Date, or (ii) the date
the Company is  required to give notice of the record or payment date of such
interest payment to the New York Stock Exchange or other applicable self-
regulatory organization or to holders of the Notes, but in any event at least
two Business Days before such record date.

          (c)  The quarter in which any notice is given pursuant to paragraphs
(a) or (b) of this Section 4.2 shall be counted as

                                      -8-
<PAGE>
 
one of the twenty quarters permitted in the maximum Extended Interest Payment
Period permitted under Section 4.1.

sale and issuance of the Notes to the Property Trustee in connection with the
sale of the Trust Securities by the Trust, the Company shall:

          (a)  pay all costs and expenses relating to the offering, sale and
     issuance of the Notes, including commissions to the underwriters payable
     pursuant to the Underwriting Agreement and the Pricing Agreement and
     compensation of the Trustee under the Indenture in accordance with the
     provisions of Section 7.06 of the Indenture;

          (b)  pay all costs and expenses of the Trust (including, but not
     limited to, costs and expenses relating to the organization of the Trust,

                                 SUBORDINATION

          Section 6.1.  Agreement to Subordinate.  The Company covenants and
agrees, and each holder of Notes issued hereunder by such holder's acceptance
thereof likewise covenants and agrees, that all Notes shall be issued subject to
the provisions of this Article VI; and each holder of a Note, whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be
bound by such provisions.

                                      -9-
<PAGE>
 
          The payment by the Company of the principal of, premium, if any, and
interest on all Notes issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness of the Company, whether
outstanding at the date of this First Supplemental Indenture or thereafter
incurred.

          No provision of this Article VI shall prevent the occurrence of any
default or Event of Default hereunder.

          Section 6.2.  Default on Senior Indebtedness.  In the event and during
the continuation of any default by the Company in the payment of principal,
premium, interest or any other payment due on any Senior Indebtedness of the
Company, or in the event that the maturity of any Senior Indebtedness of the
Company has been accelerated because of a default, then, in either case, no
payment shall be made by the Company with respect to the principal (including
redemption and sinking fund payments) of, or premium, if any, or interest on the
Notes.

          In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any holder when such payment is prohibited by the
preceding paragraph of this Section 6.2, such payment shall be held in trust for
the benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee within 90 days of such payment
of the amounts then due and owing on the Senior Indebtedness and only the
amounts specified in such notice to the Trustee shall be paid to the holders of
Senior Indebtedness.

          Section 6.3.  Liquidation; Dissolution; Bankruptcy.  Upon any payment
by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding-up or liquidation or reorganization of the Company,
whether voluntary or involuntary or in bankruptcy, insolvency, receivership or
other proceedings, all amounts due upon all Senior Indebtedness of the Company
shall first be paid in full, or payment thereof provided for in money in
accordance with its terms, before any payment is made by the Company on account
of the principal (and premium, if any) or interest on the Notes; and upon any
such dissolution or winding-up or liquidation or reorganization, any payment by
the Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the holders of the Notes or
the Trustee would be entitled to receive from the Company, except for the
provisions of this Article VI, shall be paid by the Company or by

any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the Notes or by the
Trustee under this Indenture if received by them or it, directly to the holders
of Senior Indebtedness of the Company (pro rata to such holders on the basis of
the respective amounts of Senior Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay such Senior Indebtedness in
full, in money or money's worth, after giving effect to any concurrent payment
or distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the holders of Notes or to the Trustee.

          In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or the holders of the Notes before all Senior Indebtedness of the
Company is paid in full, or provision is made for such payment in money in
accordance with its terms, such payment or distribution shall be held in trust
for the benefit of and shall be paid over or delivered to the holders of such
Senior Indebtedness or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the
payment of all Senior Indebtedness of the Company remaining unpaid to the extent
necessary to pay such Senior Indebtedness in full in money in accordance with
its terms, after giving effect to any concurrent payment or distribution to or
for the benefit of the holders of such Senior Indebtedness.

          For purposes of this Article VI, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article VI with respect
to the Notes to the payment of all Senior Indebtedness of the Company that may
at the time be outstanding, provided that (i) such Senior Indebtedness is
assumed by the new corporation, if any, resulting from any such reorganization
or readjustment, and (ii) the rights of the holders of such Senior Indebtedness
are not, without the consent of such holders, altered by such reorganization or
readjustment.  The consolidation of the Company with, or the merger of the
Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another

                                      -11-
<PAGE>
 
corporation upon the terms and conditions provided for in Article X of the
Indenture shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 6.3 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article X of the Indenture.  Nothing in Section
6.2 or in this Section 6.3 shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 7.06 of the Indenture.

          Section 6.4.  Subrogation.  Subject to the payment in full of all
Senior Indebtedness of the Company, the rights of the holders of the Notes shall
be subrogated to the rights of the holders of such Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable to such Senior Indebtedness until the principal of (and premium, if
any) and interest on the Notes shall be paid in full; and, for the purposes of
such subrogation, no payments or distributions to the holders for such Senior
Indebtedness of any cash, property or securities to which the holders of the
Notes or the Trustee would be entitled except for the provisions of this Article
VI, and no payment over pursuant to the provisions of this Article VI, to or for
the benefit of the holders of such Senior Indebtedness by holders of the Notes
or the Trustee, shall, as between the Company, its creditors other than holders
of Senior Indebtedness of the Company, and the holders of the Notes be deemed to
be a payment by the Company to or on account of such Senior Indebtedness.  It is
understood that the provisions of this Article VI are and are intended solely
for the purposes of defining the relative rights of the holders of the Notes, on
the one hand, and the holders of such Senior Indebtedness on the other hand.

          Nothing contained in this Article VI or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness of the Company, and the
holders of the Notes, the obligation of the Company which is absolute and
unconditional, to pay to the holders of the Notes the principal of (and premium,
if any) and interest on the Notes as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of the holders of the Notes and creditors of the Company, other
than the holders of Senior Indebtedness of the Company, nor shall anything
herein or therein prevent the Trustee or the holder of any Note from exercising
all remedies otherwise permitted by applicable law upon default under the
Indenture, subject to the rights, if any, under this Article VI of the holders
of such Senior Indebtedness in respect of cash, property or securities of the
Company, received upon the exercise of any such remedy.

          Upon any payment or distribution of assets of the Company referred to
in this Article VI, the Trustee, subject to

                                      -12-
<PAGE>
 
the provisions of Section 7.01 of the Indenture, and the holders of the Notes,
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the holders of the
Notes, for the purposes of ascertaining the Persons entitled to participate in
such distribution, the holders of Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
VI.

          Section 6.5.  Trustee to Effectuate Subordination.  Each holder of a
Note by such holder's acceptance thereof authorizes and directs the Trustee on
such holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article VI and appoints the
Trustee such holder's attorney-in-fact for any and all such purposes.

          Section 6.6.  Notice by the Company.  The Company shall give prompt
written notice to a Responsible Officer of the Trustee of any fact known to the
Company that would prohibit the making of any payment of monies to or by the
Trustee in respect of the Notes pursuant to the provisions of this Article VI.
Notwithstanding the provisions of this Article VI or any other provision of the
Indenture and this First Supplemental Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts that would prohibit the
making of any payment of monies to or by the Trustee in respect of the Notes
pursuant to the provisions of this Article VI unless and until a Responsible
Officer of the Trustee shall have received written notice thereof at the
Principal Office of the Trustee from the Company or a holder or holders of
Senior Indebtedness or from any trustee therefor; and before the receipt of any
such written notice, the Trustee, subject to the provisions of Section 7.01 of
the Indenture, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section 6.6 at least two Business Days prior to the date
upon which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (or premium, if
any) or interest on any Note), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
money and to apply the same to the purposes for which they were received, and
shall not be affected by any notice to the contrary that may be received by it
within two Business Days prior to such date.

          The Trustee, subject to the provisions of Section 7.01 of the
Indenture, shall be entitled to rely on the delivery to it

                                      -13-
<PAGE>
 
of a written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company (or a trustee on behalf of such holder) to establish
that such notice has been given by a holder of such Senior indebtedness or a
trustee on behalf of any such holder or holders.  In the event that the Trustee
determines in good faith that further evidence is required with respect to the
right of any Person as a holder of such Senior Indebtedness to participate in
any payment or distribution pursuant to this Article VI, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of such Senior Indebtedness held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article VI,
and if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

          Section 6.7.  Rights of the Trustee; Holders of Senior Indebtedness.
The Trustee in its individual capacity shall be entitled to all the rights set
forth in this Article VI in respect of any Senior Indebtedness at any time held
by it, to the same extent as any other holder of Senior Indebtedness, and
nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder.

          With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article VI, and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness
shall be read into this Indenture against the Trustee.  The Trustee shall not be
deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Section 7.01 of the Indenture, the Trustee shall
not be liable to any holder of such Senior Indebtedness if it shall pay over or
deliver to holders of Notes, the Company or any other Person money or assets to
which any holder of such Senior Indebtedness shall be entitled by virtue of this
Article VI or otherwise.

          Section 6.8.  Subordination May Not Be Impaired.  No right of any
present or future holder of any Senior Indebtedness of the Company to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of the Indenture,
regardless of any knowledge thereof that any such holder may have or otherwise
be charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the

                                      -14-
<PAGE>
 
consent of or notice to the Trustee or the holders of the Notes, without
incurring responsibility to the holders of the Notes and without impairing or
releasing the subordination provided in this Article VI or the obligations
hereunder of the holders of the Notes to the holders of such Senior
Indebtedness, do any one or more the following: (i) change the manner, place or
terms of payment or extend the time of payment of, or renew or alter, such
Senior Indebtedness, or otherwise amend or supplement in any manner such Senior
Indebtedness or any instrument evidencing the same or any agreement under which
such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

                          COVENANT TO LIST ON EXCHANGE

          Section 7.1.  Listing on Exchange.  If the Notes are to be issued as a
Global Security in connection with the distribution of the Notes to the holders
of the Preferred Securities issued by the Trust upon a Dissolution Event, the
Company will use its best efforts to list such Notes on the New York Stock
Exchange or on such other exchange as the Preferred Securities are then listed.

                                    DUE ____


          COMMONWEALTH EDISON COMPANY, an Illinois corporation (the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to _______ or
registered assigns, the principal sum of ____________  Dollars on ____________,
____ (or on such later date before ___________, _____ if the Company elects to
extend the maturity date as further described herein), and to pay interest on
said principal sum from ___________, ____ or from the most recent interest
payment date (each such date, an "Interest Payment Date") to which interest has
been paid or duly provided for, quarterly (subject to deferral as set forth
herein) in arrears on [March 31, June 30, September 30 and December 31] of each
year commencing __________, 1995 at the rate of ____% per annum until the
principal hereof shall have become due and payable, and on any overdue principal
and premium, if any, and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest compounded quarterly at the same rate per annum.  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.  In the event that any date on which
interest is payable on this Note is not a Business Day, then payment of interest
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.  The interest
installment 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 Note (or one or more Predecessor Securities, as defined in

                                      -16-

said Indenture) is registered at the close of business on the regular record
date for such interest installment [which shall be the close of business on the
Business Day next preceding such Interest Payment Date.] [IF PURSUANT TO THE
PROVISIONS OF Section 2.11(C) OF THE INDENTURE THE NOTES ARE NO LONGER
REPRESENTED BY A GLOBAL SECURITY -- which shall be the close of business on the
________ day preceding such Interest Payment Date.] Any such interest
installment not punctually paid or duly provided for shall forthwith cease to be
payable to the registered holders on such regular record date, and may be paid
to the person in whose name this Note (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 registered holders of this series of Notes not less than ten (10)
days prior to such special record date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes 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 the interest on this Note shall be payable at the
office or agency of the Trustee maintained for that purpose in ________, in any
coin or currency of the United States of America which at the time of payment is
legal tender for payment of public and private debts; provided, however, that
payment of interest may be made at the option of the Company by check mailed to
the registered holder at such address as shall appear in the Security Register.
Notwithstanding the foregoing, so long as the Holder of this Note is the
Property Trustee, the payment of the principal of (and premium, if any) and
interest on this Note will be made at such place and to such account as may be
designated by the Property Trustee.

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

          This Note shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of

          Unless the Certificate of Authentication hereon has been executed by
the Trustee referred to on the reverse side hereof, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

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

          IN WITNESS WHEREOF, the Company has caused this instrument to be

          WILMINGTON TRUST COMPANY,      _____________________

          as Trustee

               Authorized Signatory           Authorized Signatory



                                 (FORM OF REVERSE OF NOTE)

          This Note is one of a duly authorized series of Notes of the Company
(herein sometimes referred to as the "Notes"), specified in the Indenture, all
issued or to be issued in one or more series under and pursuant to an Indenture
dated as of __________, 1995, duly executed and delivered between the Company
and Wilmington Trust Company, not in its individual capacity but solely as
trustee (the "Trustee"), as supplemented by the First Supplemental Indenture
dated as of ____________, 1995 between the Company and the Trustee (the
Indenture as so supplemented, the "Indenture"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the holders of the Notes.  By the terms of the
Indenture, the Notes are issuable in series which may vary as to amount, date of
maturity, rate of interest and in other respects as in the Indenture provided.
This series of Notes is limited in aggregate principal amount as specified in
said First Supplemental Indenture.

          Because of the occurrence and continuation of a Tax Event, in certain
circumstances this Note will become due and payable at the principal amount
together with any interest accrued thereon (the "Redemption Price").  The
Redemption Price 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.  The
Company shall have the right to redeem this Note at the option of the Company,
without premium or penalty, in whole or in part at any time on or after ______,
2000 (an "Optional Redemption"), at a redemption price equal to 100% of the
principal amount plus any accrued but unpaid interest to the date of such
redemption (the "Optional Redemption Price").  Any optional redemption pursuant
to this paragraph will be made upon

                                      -19-
<PAGE>
 
not less than 30 days' nor more than 60 days' notice, at the Optional Redemption
Price.  If the Notes are only partially redeemed by the Company pursuant to an
Optional Redemption, the Notes 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 Notes are registered as a Global Security, the Depositary shall
determine by lot the principal amount of such Notes held by each Noteholder to
be redeemed.

          In the event of redemption of this Note in part only, a new Note or
Notes of this series for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

          In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes 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 not less than a majority in
aggregate principal amount of the Notes of each series affected 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 any supplemental indenture or of
modifying in any manner the rights of the Holders of the Notes; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Notes of any series, or reduce the principal amount thereof, or reduce
the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, without the consent of the Holder
of each Note so affected or (ii) reduce the aforesaid percentage of Notes, the
Holders of which are required to consent to any such supplemental indenture,
without the consent of the Holders of each Note then outstanding and affected
thereby.  The Indenture also contains provisions permitting the Holders of a
majority in aggregate principal amount of the Notes of any series at the time
outstanding affected thereby, on behalf of all of the Holders of the Notes of
such series, to waive any past default in the performance of any of the
covenants contained in the Indenture, or established pursuant to the Indenture
with respect to such series, and its consequences, except a default in the
payment of the principal of or premium, if any, or interest on any of the Notes
of such series.  Any such consent or waiver by the registered Holder of this
Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such Holder and upon all future Holders and owners of this Note and
of any Note issued in exchange herefor or in place hereof (whether by
registration of transfer or otherwise), irrespective of whether

                                      -20-
<PAGE>
 
or not any notation of such consent or waiver is made upon this Note.

          No reference herein to the Indenture and no provision of this Note 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 Note at the time and place and at the rate and in the money
herein prescribed.

          The Company shall have the right at any time during the term of the
Notes, from time to time to extend the interest payment period of such Notes for
up to twenty (20) consecutive quarters (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 Notes 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 extend such Extended Interest Payment Period, provided that such
Extended Interest Payment Period together with all such further extensions
thereof shall not exceed twenty (20) consecutive quarters or extend beyond the
maturity of the Notes.  At the termination of any such Extended Interest Payment
Period and upon the payment of all accrued and unpaid interest and any
additional amounts then due, the Company may select a new Extended Interest
Payment Period.

          As provided in the Indenture and subject to certain limitations
therein set forth, this Note is transferable by the registered holder hereof on
the Security Register of the Company, upon surrender of this Note for
registration of transfer at the office or agency of the Trustee in ________
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Trustee duly executed by the registered
holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Notes of authorized denominations and for the same aggregate principal
amount 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 Note,
the Company, the Trustee, any paying agent and any Security Registrar may deem
and treat the registered holder hereof as the absolute owner hereof (whether or
not this Note 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 interest due hereon and for all other purposes, and neither the Company
nor the Trustee

                                      -21-
<PAGE>
 
nor any paying agent nor any Security Registrar shall be affected by any notice
to the contrary.

          No recourse shall be had for the payment of the principal of or the
interest on this Note, 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 corporation, 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.

          [The Notes of this series are issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof.] [This Global
Security is exchangeable for Notes in definitive form only under certain limited
circumstances set forth in the Indenture.  Notes of this series so issued are
issuable only in registered form without coupons in denominations of $25 and any
integral multiple thereof.] As provided in the Indenture and subject to certain
limitations [herein and] therein set forth, Notes of this series [so issued] are
exchangeable for a like aggregate principal amount of Notes of this series of a
different authorized denomination, as requested by the Holder surrendering the
same.

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

trustee (the "Preferred Guarantee Trustee"), for the benefit of the Holders (as
defined herein) from time to time of the Preferred Securities (as defined
herein) of ComEd Financing I, a Delaware statutory business trust (the

                              W I T N E S S E T H:

payments under the Common Securities Guarantee are subordinated to the rights of
Holders of Preferred Securities to receive Guarantee Payments under this
Guarantee Agreement;

     NOW, THEREFORE, in consideration of the purchase by each Holder of
Preferred Securities, which purchase the Guarantor hereby agrees shall benefit
the Guarantor, the Guarantor executes and delivers this Guarantee Agreement for

except to a Holder of Preferred Securities exercising his or her rights pursuant
to Section 5.4(b) or to a Successor Preferred Guarantee Trustee on acceptance by

benefit of the Holders of the Preferred Securities.

          (c) The Preferred Guarantee Trustee, before the occurrence of any
Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Guarantee Agreement, and no implied covenants shall be read into
this Guarantee Agreement against the Preferred Guarantee Trustee.  In case an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6), the Preferred Guarantee Trustee shall exercise such of the rights
and powers vested in it by this Guarantee Agreement, and use the same degree of
care and skill in its exercise thereof, as a prudent person would exercise or
use under the circumstances in the conduct of his or her own affairs.

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

                                      -7-
<PAGE>
 
               (i) prior to the occurrence of any Event of Default and after the
     curing or waiving of all such Events of Default that may have occurred:

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

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

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

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

               (iv) no provision of this Guarantee Agreement shall require the
     Preferred Guarantee Trustee to expend or risk its own funds or otherwise
     incur

                                      -8-
<PAGE>
 
     personal financial liability in the performance of any of its duties or in
     the exercise of any of its rights or powers, if the Preferred Guarantee
     Trustee shall have reasonable grounds for believing that the repayment of
     such funds or liability is not reasonably assured to it under the terms of
     this Guarantee Agreement or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          Section 3.2.  Certain Rights of Preferred Guarantee Trustee.  (a)
Subject to the provisions of Section 3.1:

               (i)  The Preferred Guarantee Trustee may rely and shall be fully

     indebtedness or other paper or document believed by it to be genuine and to
     have been signed, sent or presented by the proper party or parties.

     Guarantee Agreement shall be sufficiently evidenced by a Direction or an
     Officers' Certificate.

     Agreement, the Preferred Guarantee Trustee shall deem it desirable that a
     matter be proved or established before taking, suffering or omitting any
     action hereunder, the Preferred Guarantee Trustee (unless other evidence is
     herein specifically prescribed) may, in the absence of bad faith on its
     part, request and rely upon an Officers' Certificate which, upon receipt of
     such request, shall be promptly delivered by the Guarantor.

               (iv)  The Preferred Guarantee Trustee shall have no duty to see
     to any recording, filing or registration of any instrument (or any
     rerecording, refiling or registration thereof).

<PAGE>
 
     concerning the administration of this Guarantee Agreement from any court of
     competent jurisdiction.

               (vi)  The Preferred Guarantee Trustee shall be under no
     obligation to exercise any of the rights or powers vested in it by this
     Guarantee Agreement at the request or direction of any Holder, unless such
     Holder shall have provided to the Preferred Guarantee Trustee such adequate
     security and indemnity as would satisfy a reasonable person in the position

     attorneys' fees and expenses) and liabilities that might be incurred by it
     in complying with such request or direction, including such reasonable
     advances as may be requested by the Preferred Guarantee Trustee; provided
     that, nothing contained in this Section 3.2(a)(vi) shall be taken to
     relieve the Preferred Guarantee Trustee, upon the occurrence of an Event of
     Default, of its obligation to exercise the rights and powers vested in it
     by this Guarantee Agreement.

               (vii)  The Preferred Guarantee Trustee shall not be bound to make
     any investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document, but the Preferred Guarantee
     Trustee, in its discretion, may make such further inquiry or investigation
     into such facts or matters as it may see fit.

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

               (ix)  Any action taken by the Preferred Guarantee Trustee or its
     agents hereunder shall bind the Holders of the Preferred Securities, and
     the signature of the Preferred Guarantee Trustee or its agents alone shall
     be sufficient and effective to perform any such action.  No third party
     shall be required to inquire as to the authority of the Preferred Guarantee
     Trustee to so act or as to its compliance with any of the terms and
     provisions of this Guarantee Agreement, both of which shall be conclusively
     evidenced by the Preferred Guarantee Trustee's or its agent's taking such
     action.

               (x)  Whenever in the administration of this Guarantee Agreement
     the Preferred Guarantee Trustee shall deem it desirable to receive

     other action hereunder, the Preferred Guarantee Trustee (i) may request
     instructions from the Holders of a Majority in liquidation amount of the
     Preferred Securities, (ii) may refrain from enforcing such remedy or right
     or taking such other action until such instructions are received, and (iii)
     shall be protected in acting in accordance with such instructions.

          (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Preferred Guarantee Trustee to perform any act or
acts or exercise any right, power, duty or obligation conferred or imposed on it
in any jurisdiction in which it shall be illegal, or in which the Preferred
Guarantee Trustee shall be unqualified or incompetent in accordance with
applicable law, to perform any such act or acts or to exercise any such right,
power, duty or obligation.  No permissive power or authority available to the
Preferred Guarantee Trustee shall be construed to be a duty.

          Section 3.3.  Not Responsible for Recitals or Issuance of Guarantee.

Guarantor, and the Preferred Guarantee Trustee does not assume any
responsibility for their correctness.  The Preferred Guarantee Trustee makes no

     set forth in its most recent report of condition so published.

Trustee may be appointed or removed without cause at any time by the

appointed and has accepted such appointment by written instrument executed by
such Successor Preferred Guarantee Trustee and delivered to the Guarantor.

          (c) The Preferred Guarantee Trustee appointed to office shall hold
office until a Successor Preferred Guarantee Trustee shall have been appointed
or until its removal or resignation.  The Preferred Guarantee Trustee may resign
from office (without need for prior or subsequent accounting) by an instrument
in writing executed by the Preferred Guarantee Trustee and delivered to the
Guarantor, which resignation shall not take effect until a Successor Preferred
Guarantee Trustee has been appointed and has accepted such appointment by
instrument in writing executed by such Successor Preferred Guarantee Trustee and
delivered to the Guarantor and the resigning Preferred Guarantee Trustee.

          (d) If no Successor Preferred Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery to the Guarantor of an instrument of resignation, the
resigning Preferred Guarantee Trustee may petition any court of competent
jurisdiction for appointment of a Successor Preferred Guarantee Trustee.  Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Preferred Guarantee Trustee.

                                   GUARANTEE

          Section 5.1.  Guarantee.  The Guarantor irrevocably and
unconditionally agrees to pay in full to the Holders the Guarantee Payments
(without duplication of amounts theretofore paid by the Issuer), as and when
due, regardless of any defense, right of set-off or counterclaim that the Issuer
may have or assert.  The Guarantor's obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by the Guarantor to the
Holders or by causing the Issuer to pay such amounts to the Holders.

          Section 5.2.   Waiver of Notice and Demand.  The Guarantor hereby
waives notice of acceptance of this Guarantee Agreement and of any liability to
which it applies or may apply, presentment, demand for payment, any right to
require a proceeding first against the Issuer or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.

          Section 5.3.  Obligations Not Affected.  The obligations, covenants,
agreements and duties of the Guarantor under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

          (a) the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Preferred Securities
     to be performed or observed by the Issuer;

          (b) the extension of time for the payment by the Issuer of all or any
     portion of the Distributions, Redemption Price, Liquidation Distribution or
     any other sums payable under the terms of the Preferred Securities or the
     extension of time for the performance of any other obligation under,
     arising out of, or in connection with, the Preferred Securities (other than
     an extension of time for payment of Distributions, Redemption Price,
     Liquidation Distribution or other sum payable that results from the
     extension of any interest payment period on the Debentures or any extension
     of the maturity date of the Debentures permitted by the Indenture);

          (c) any failure, omission, delay or lack of diligence on the part of
     the Holders to enforce, assert or exercise any right, privilege, power or
     remedy conferred on the Holders pursuant to the terms of the Preferred
     Securities, or any action on the part of the Issuer granting indulgence or
     extension of any kind;

                                      -13-
<PAGE>
 
          (d) the voluntary or involuntary liquidation, dissolution, sale of any
     collateral, receivership, insolvency, bankruptcy, assignment for the
     benefit of creditors, reorganization, arrangement, composition or
     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

          (e) any invalidity of, or defect or deficiency in, the Preferred
     Securities;

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

          (g) any other circumstance whatsoever that might otherwise constitute
     a legal or equitable discharge or defense of a guarantor, it being the
     intent of this Section 5.3 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.

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

          Section 5.4.   Rights of Holders.  (a) The Holders of a Majority in
liquidation amount of the Preferred Securities have the right to direct the
time, method and place of conducting of any proceeding for any remedy available
to the Preferred Guarantee Trustee in respect of this Guarantee Agreement or
exercising any trust or power conferred upon the Preferred Guarantee Trustee
under this Guarantee Agreement.

          (b) If the Preferred Guarantee Trustee fails to enforce this Guarantee
Agreement, any Holder of Preferred Securities may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Guarantee
Agreement, without first instituting a legal proceeding against the Issuer, the
Preferred Guarantee Trustee or any other Person.

          Section 5.5.  Guarantee of Payment.  This Guarantee Agreement creates
a guarantee of payment and not of collection.

          Section 5.6.  Subrogation.  The Guarantor shall be subrogated to all
(if any) rights of the Holders of Preferred Securities against the Issuer in
respect of any amounts paid to such Holders by the Guarantor under this
Guarantee Agreement; provided, however, that the Guarantor shall not (except to
the extent required by mandatory provisions of law) be entitled to enforce or
exercise any 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
Guarantee Agreement, if, at the time of any such payment, any amounts are due
and unpaid under this Guarantee Agreement.  If any amount shall be paid to the
Guarantor in violation of the preceding

                                      -14-
<PAGE>
 
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

          Section 5.7.  Independent Obligations.  The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Issuer
with respect to the Preferred Securities, and that the Guarantor shall be liable
as principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.3 hereof.


                                   ARTICLE VI
                   LIMITATION OF TRANSACTIONS; SUBORDINATION

          Section 6.1.   Limitation of Transaction.  So long as any Preferred
Securities remain outstanding, if there shall have occurred an Event of Default
or an event of default under the Declaration, then (a) the Guarantor shall not,
and shall cause any subsidiary of the Guarantor which is not a wholly-owned
subsidiary of the Guarantor not to, declare or pay any dividend on, or make any
distribution with respect to, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock or the capital stock of any
such subsidiary, and (b) the Guarantor shall not make any payment of interest,
principal or premium, if any, on or repay, repurchase or redeem any debt
securities issued by the Guarantor which rank pari passu with or junior to the
Debentures.

          Section 6.2.  Ranking.  This Guarantee Agreement will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to all other liabilities of the Guarantor, including the
Subordinated Notes, except those liabilities of Guarantor made pari passu or
subordinate by their terms, (ii) pari passu with the most senior preferred stock
now or hereafter issued by the Guarantor and with any guarantee now or hereafter
entered into by the Guarantor in respect of any preferred stock of any Affiliate
of the Guarantor, and (iii) senior to the Guarantor's common stock.


                                  ARTICLE VII
                                  TERMINATION

          Section 7.1.  Termination.  This Guarantee Agreement shall terminate
upon (i) full payment of the Redemption Price of all Preferred Securities, (ii)
upon the distribution of the Debentures to the Holders of all of the Preferred
Securities or (iii) upon full payment of the amounts payable in accordance with
the Declaration upon liquidation of the Issuer.  Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated, as
the case may be, if at any

                                      -15-

time any of Preferred Securities must restore payment of any sums paid under
the Preferred Securities or under this Preferred Securities Guarantee.

any Covered Person for any loss, damage or claim incurred by reason of any act
or omission performed or omitted by such Indemnified Person in good faith in
accordance with this Guarantee Agreement and in a manner that such Indemnified
Person reasonably believed to be within the scope of the authority conferred on

by applicable law, the Guarantor shall indemnify and hold harmless each
Indemnified Person from and against any loss, damage or claim incurred by such
Indemnified Person by reason of any act or omission performed or omitted by such
Indemnified Person in good faith in accordance with this Guarantee Agreement and
in a manner such Indemnified Person reasonably believed to be within the scope

     Re:  ComEd Financing I
          -----------------

Ladies and Gentlemen:

     We have acted as special Delaware counsel for Commonwealth Edison Company,

trust (the "Trust"), in connection with the matters set forth herein.  At your

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

          (a)  The Certificate of Trust of the Trust, dated July 19, 1995 (the

     State of Delaware (the "Secretary of State") on July 21, 1995;

          (b)  The Declaration of Trust, dated as of July 19, 1995, between
     ComEd, as Sponsor, and the trustees of the Trust named therein;

          (c)  The preliminary prospectus, dated ___________, 1995 (the
     "Prospectus"), relating to the __% Trust Originated Preferred Securities of

     assets of the Trust (each, a "Preferred Security" and collectively, the
     "Preferred Securities");

          (d)  The Registration Statement on Form S-3 (the "Registration
     Statement"), including a form of Amended and Restated Declaration of Trust,
     to be entered into among ComEd, as Sponsor, and the trustees of the Trust

     the Trust with the Securities and Exchange Commission on or about July 27,
     1995;

          (e)  A Certificate of Good Standing for the Trust, dated July 21,

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

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

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

          For purposes of this opinion, we have assumed (i) the Trust Agreement
and the Certificate are in full force and effect and have not been amended, (ii)
except to the extent provided in paragraph 1 below, the due organization or due
formation, as the case may be, and valid existence in good standing of each
party to the documents examined by us under the laws of the jurisdiction
governing its organization or formation, (iii) the legal capacity of natural
persons who are parties to the documents examined by us, (iv) the power and
authority to each of the parties to the documents examined by us to execute and
deliver, and to perform its obligations under, such documents, (v) the due
authorization, execution and delivery by all parties thereto of all documents
examined by us, (vi) the receipt by each Person to whom a Preferred Security is
to be issued by the Trust (collectively, the "Preferred Security Holders") of a
Preferred Securities Certificate for such Preferred Security and the payment for
the Preferred Security acquired by it, in accordance with the Trust Agreement,

the Registration Statement and the Prospectus, and (vii) the issuance and sale
of the Preferred Securities to the Preferred Security Holders in accordance with
the Trust Agreement, the Registration Statement and the Prospectus.  We have not
participated in the preparation of the Registration Statement or the Prospectus
and assume no responsibility for their contents.

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

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

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

          2.  The Preferred Securities will represent valid and, subject to the
     qualifications set forth in paragraph 3 below, fully paid and nonassessable
     undivided beneficial interest in the assets of the Trust.

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

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  We hereby
consent to the use of our name under the heading "Legal Matters" in the
Prospectus.  In giving the foregoing consents, we do not thereby admit that we
come within the category of Persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules

               _____% Trust Originated
               Preferred Securities ("TOPrS")
               ------------------------------


Ladies and Gentlemen:

          We refer to the Registration Statement on Form S-3  (the "Registration
Statement") being filed by Commonwealth Edison Company (the "Company") and ComEd
Financing I (the "Trust") with the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the "Securities Act"),
relating to the registration of (i) not to exceed $200,000,000 of     % Trust
Originated Preferred Securities ($25 liquidation amount) (the "Preferred
Securities") of the Trust, (ii) the guarantee of the Preferred Securities by the
Company (the "Preferred Securities Guarantee") and (iii)     % Subordinated Debt
Securities (the "Debt Securities") of the Company.  The Preferred Securities
Guarantee is to be issued pursuant to the Preferred Securities Guarantee
Agreement dated as of             , 1995 (the "Preferred Securities Guarantee
Agreement") between the Company and Wilmington Trust Company, as trustee (the
"Agreement Trustee").  The Debt Securities are to be issued under an Indenture
dated as of             , 1995 between the Company and Wilmington Trust Company,
as trustee (the "Indenture Trustee"), and a supplemental indenture thereto dated
as of             , 1995 (collectively, the "Indenture").

          We are familiar with the proceedings to date with respect to the
proposed execution and delivery of the Preferred Securities Guarantee and the
proposed issuance and sale of the Debt Securities and have examined such
records, documents and questions of law, and satisfied ourselves as to such
matters of fact, as we have considered relevant and necessary as a basis for
this opinion.

          Based on the foregoing, we are of the opinion that:

          1.   The Company is duly incorporated and validly existing under the
laws of the State of Illinois.

          2.   The Company has corporate power and authority to execute and
deliver the Preferred Securities Guarantee Agreement and the Indenture and to
authorize and sell the Debt Securities.

          3.   The Preferred Securities Guarantee will be a legally issued and
binding obligation of the Company (except to the extent enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer or other similar laws affecting the enforcement of
creditors' rights generally and by the effect of general principles of equity,
regardless of whether enforceability is considered in a proceeding in equity or
at law) when (i) the Registration Statement, as finally amended, shall have
become effective under the Securities Act; (ii) the Preferred Securities
Guarantee Agreement shall have been qualified under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"), and duly executed and delivered by
the Company and the Agreement Trustee; (iii) the Preferred Securities shall have
been legally issued, as contemplated by paragraph 4 below; and (iv) the
Preferred Securities Guarantees shall have been duly executed and delivered as
provided in the Preferred Securities Guarantee Agreement.

          4.   The Debt Securities will be legally issued and binding
obligations of the Company (except to the extent enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer or other similar laws affecting the enforcement of creditors' rights
generally and by the effect of general principles of equity, regardless of
whether enforceability is considered in a proceeding in equity or at law) when
(i) the Registration Statement, as finally amended, shall have become effective
under the Securities Act; (iii) the Indenture shall have been qualified under
the Trust Indenture Act and duly executed and delivered by the Company and the
Indenture Trustee; (iii) the Company's Board of Directors or duly authorized
officers of the Company shall have duly adopted final resolutions authorizing
the issuance and sale of the Debt Securities, as contemplated by the
Registration Statement and the Indenture; and (iv) the Debt Securities shall
have been duly executed and authenticated as provided in the Indenture and shall
have been duly delivered to the purchasers thereof against payment of the agreed
consideration therefor.

          We do not find it necessary for the purposes of this opinion to cover,
and accordingly we express no opinion as to,

the application of the securities or blue sky laws of the various states to the
execution and delivery of the Preferred Securities Guarantee or the sale of the
Debt Securities.

          We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to all references to our firm included in or made a

Ladies and Gentlemen:

     Reference is made to the Registration Statement on Form S-3 (the

Commission by Commonwealth Edison Company ("ComEd") and ComEd Financing I (the
"Trust") and the prospectus contained therein (the "Prospectus") which forms a

     We have acted as special tax counsel to ComEd and the Trust in connection
with the preparation of the Registration Statement and the Prospectus.  The
statements contained in the Prospectus under the caption "Certain Federal Income
Tax Consequences," to the extent they constitute matters of federal income tax
law or legal conclusions with respect thereto, have been prepared or reviewed by
us, and, in our opinion, are correct in all material respects.

whatsoever.  This opinion letter is limited to the matters stated herein and no
opinion is implied or may be inferred beyond the matters expressly stated
herein.  This opinion letter shall not be construed as or deemed to be a
guaranty or insuring agreement.

     the holders of such of the series of Preferred Stock as are from time to
     time outstanding shall not be required for the issuance by the Board of
     Directors of any other series of Preferred Stock whether or not the powers,
     preferences and rights of such other series shall be fixed by the Board of

     rights of such outstanding series, or any of them; provided, however, that

     greater proportion as shall be therein fixed) of the outstanding shares of
     such series voting thereon shall be required for the issuance of any or all
     other series of Preferred Stock.

     (f)  Subject to the provisions of section (e), shares of any series of
     Preferred Stock may be issued from time to time as the Board of Directors
     of the Corporation shall determine and on such terms and for such
     consideration as shall be fixed by the Board of Directors.

     FIFTH: - (a)  The business and affairs of the Corporation shall be
     conducted and managed by a Board of Directors.  The number of directors
     constituting the entire Board shall be not less than five nor more than

     Board, provided, however, that the number of directors shall not be reduced
     so as to shorten the term of any director at the time in office, and
     provided further, that the number of directors constituting the whole Board
     shall be twenty-four until otherwise fixed by a majority of the whole
     Board.

     (b)  The Board of Directors shall be divided into three classes, as nearly
     equal in number as the then total number of directors constituting the

     year.  At the annual meeting of stockholders in 1982, directors of the
     first class shall be elected to hold office for a term expiring at the next
     succeeding annual meeting, directors of the second class shall be elected
     to hold office for a term expiring at the second succeeding annual meeting
     and directors of the third class shall be elected to hold office for a term
     expiring at the third succeeding annual meeting.  Any vacancies in the
     Board of Directors for any reason, and any newly created directorships
     resulting from any increase in the directors, may be filled by the Board of
     Directors, acting by a majority of the directors then in office, although
     less than a quorum, and any directors so chosen shall hold office until the
     next annual election of directors.  At such election, the stockholders
     shall elect a successor to such director to hold office until the next
     election of the class for which such director shall have been chosen and
     until his successor shall be elected and qualified.  No decrease in the
     number of directors shall shorten the term of any incumbent director.

     Incorporation or the By-Laws of the Corporation (and notwithstanding the
     fact that some lesser percentage may be specified by law, this Charter or
     Act of Incorporation or the By-Laws of the Corporation), any director or
     the entire Board of Directors of the Corporation may be removed at any time
     without cause, but only by the affirmative vote of the holders of two-
     thirds or more of the outstanding shares of capital stock of the
     Corporation entitled to vote generally in the election of directors
     (considered for this purpose as one class) cast at a meeting of the
     stockholders called for

     Directors or by any stockholder entitled to vote for the election of
     directors.  Such nominations shall be made by notice in writing, delivered
     or mailed by first class United States mail, postage prepaid, to the
     Secretary of the Corporation not less than 14 days nor more than 50 days
     prior to any meeting of the stockholders called for the election of
     directors; provided, however, that if less than 21 days' notice of the
     meeting is given to stockholders, such written notice shall be delivered or
     mailed, as prescribed, to the Secretary of the Corporation not later than
     the close of the seventh day following the day on which notice of the
     meeting was mailed to stockholders.  Notice of nominations which are
     proposed by the Board of Directors shall be given by the Chairman on behalf
     of the Board.

     business address and, if known, residence address of each nominee proposed
     in such notice, (ii) the principal occupation or employment of such nominee
     and (iii) the number of shares of stock of the Corporation which are
     beneficially owned by each such nominee.

     (f)  The Chairman of the meeting may, if the facts warrant, determine and
     declare to the meeting that a nomination was not made in accordance with
     the foregoing procedure, and if he should so determine, he shall so declare
     to the meeting and the defective nomination shall be disregarded.

     (g)  No action required to be taken or which may be taken at any annual or
     special meeting of stockholders of the Corporation may be taken without a
     meeting, and the power of stockholders to consent in writing, without a
     meeting, to the taking of any action is specifically denied.

     SIXTH: - The Directors shall choose such officers, agent and servants as
     may be provided in the By-Laws as they may from time to time find necessary
     or proper.

     SEVENTH: - The Corporation hereby created is hereby given the same powers,
     rights and privileges as may be conferred upon corporations organized under
     the Act entitled "An Act Providing a General Corporation Law", approved

     EIGHTH: - This Act shall be deemed and taken to be a private Act.

     NINTH: - This Corporation is to have perpetual existence.

          Preferred Stock as a class, to elect one or more directors of the
          Corporation if there shall have been a default in the payment of

          (2)  After distribution in full of the preferential amount, if any,
          (fixed in accordance with the provisions of section (b) of this
          Article FOURTH), to be distributed to the holders of Preferred Stock

          proportion to the number of shares of Common Stock held by them
          respectively.

          (3)  Except as may otherwise be required by law or by the provisions
          of such resolution or resolutions as may be adopted by the Board of
          Directors pursuant to section (b) of this Article FOURTH, each holder

<PAGE>
 
     class or series or any additional shares of any class or series to be
     issued by reason of any increase of the authorized capital stock of the
     Corporation of any class or series, or bonds, certificates of indebtedness,
     debentures or other securities convertible into or exchangeable for stock
     of the Corporation of any class or series, or carrying any right to
     purchase stock of any class or series, but any such unissued stock,
     additional authorized issue of shares of any class or series of stock or
     securities convertible into or exchangeable for stock, or carrying any
     right to purchase stock, may be issued and disposed of pursuant to
     resolution of the Board of Directors to such persons, firms, corporations

     be deemed advisable by the Board of Directors in the exercise of its sole
     discretion.

     (e)  The relative powers, preferences and rights of each series of
     Preferred Stock in relation to the relative powers, preferences and rights
     of each other series of Preferred Stock shall, in each case, be as fixed
     from time to time by the Board of Directors in the resolution or
     resolutions adopted pursuant to authority granted in section (b) of this
     Article FOURTH and the consent, by class or series vote or otherwise, of
     the holders of such of the series of Preferred Stock as are from time to
     time outstanding shall not be required for the issuance by the Board of
     Directors of any other series of Preferred Stock whether or not the powers,
     preferences and rights of such other series shall be fixed by the Board of
     Directors as senior to, or on a parity with, the powers, preferences and
     rights of such outstanding series, or any of them; provided, however, that
     the Board of Directors may provide in the resolution or resolutions as to
     any series of Preferred Stock adopted pursuant to section (b) of this
     Article FOURTH that the consent of the holders of a majority (or such
     greater proportion as shall be therein fixed) of the outstanding shares of
     such series voting thereon shall be required for the issuance of any or all
     other series of Preferred Stock.

     (f)  Subject to the provisions of section (e), shares of any series of
     Preferred Stock may be issued from time to time as the Board of Directors
     of the Corporation shall determine and on such terms and for such
     consideration as shall be fixed by the Board of Directors.

     (g)  Shares of Common Stock may be issued from time to time as the Board of

     (h)  The authorized amount of shares of Common Stock and of Preferred Stock

     the Corporation entitled to vote thereon.

     FIFTH: - (a)  The business and affairs of the Corporation shall be
     conducted and managed by a Board of Directors.  The number of directors
     constituting the entire Board shall be not less than five nor more than
     twenty-five as fixed from time to time by vote of a majority of the whole
     Board, provided, however, that the number of directors shall not be reduced
     so as to shorten the term of any director at the time in office, and
     provided further, that the number of directors constituting the whole Board
     shall be twenty-four until otherwise fixed by a majority of the whole
     Board.

     (b)  The Board of Directors shall be divided into three classes, as nearly
     equal in number as the then total number of directors constituting the
     whole Board permits, with the term of office of one class expiring each
     year.  At the annual meeting of stockholders in 1982, directors of the
     first class shall be elected to hold office for a term expiring at the next
     succeeding annual meeting, directors of the second class shall be elected
     to hold office for a term expiring at the second succeeding annual meeting
     and directors of the third class shall be elected to hold office for a term
     expiring at the third succeeding annual meeting.  Any vacancies in the
     Board of Directors for any reason, and any newly created directorships
     resulting from any increase in the directors, may be filled by the Board of
     Directors, acting by a majority of the directors then in office, although
     less than a quorum, and any directors so chosen shall hold office until the
     next annual election of directors.  At such election, the stockholders
     shall elect a successor to such director to hold office until the next
     election of the class for which such director shall have been chosen and
     until his successor shall be elected and qualified.  No decrease in the
     number of directors shall shorten the term of any incumbent director.

     Incorporation or the By-Laws of the Corporation (and notwithstanding the
     fact that some lesser percentage may be specified by law, this Charter or
     Act of Incorporation or the By-Laws of the Corporation), any director or
     the entire Board of Directors of the Corporation may be removed at any time
     without cause, but only by the affirmative vote of the holders of two-
     thirds or more of the outstanding shares of capital stock of the
     Corporation entitled to vote generally in the election of directors
     (considered for this purpose as one class) cast at a meeting of the
     stockholders called for

     Directors or by any stockholder entitled to vote for the election of
     directors.  Such nominations shall be made by notice in writing, delivered
     or mailed by first class United States mail, postage prepaid, to the
     Secretary of the Corporation not less than 14 days nor more than 50 days
     prior to any meeting of the stockholders called for the election of
     directors; provided, however, that if less than 21 days' notice of the
     meeting is given to stockholders, such written notice shall be delivered or
     mailed, as prescribed, to the Secretary of the Corporation not later than
     the close of the seventh day following the day on which notice of the
     meeting was mailed to stockholders.  Notice of nominations which are
     proposed by the Board of Directors shall be given by the Chairman on behalf
     of the Board.

     in such notice, (ii) the principal occupation or employment of such nominee
     and (iii) the number of shares of stock of the Corporation which are
     beneficially owned by each such nominee.

     (f)  The Chairman of the meeting may, if the facts warrant, determine and
     declare to the meeting that a nomination was not made in accordance with
     the foregoing procedure, and if he should so determine, he shall so declare
     to the meeting and the defective nomination shall be disregarded.

     (g)  No action required to be taken or which may be taken at any annual or
     special meeting of stockholders of the Corporation may be taken without a
     meeting, and the power of stockholders to consent in writing, without a
     meeting, to the taking of any action is specifically denied.

     SIXTH: - The Directors shall choose such officers, agent and servants as
     may be provided in the By-Laws as they may from time to time find necessary
     or proper.

     the affirmative vote of the holders of two-thirds or more of the
     outstanding shares of capital stock of the Corporation entitled to vote
     generally in the election of directors (considered for this purpose as one

          by reference to or inference from the terms of any other clause of
          this or any other paragraph in this charter, but that the objects,

          shall be regarded as independent objects, purposes and powers.

     FOURTH: - (a)  The total number of shares of all classes of stock which the
     Corporation shall have authority to issue is forty-one million (41,000,000)
     shares, consisting of:

          $1.00 per share (hereinafter referred to as "Common Stock").

     (b)  Shares of Preferred Stock may be issued from time to time in one or
     more series as may from time to time be determined by the Board of

     any one series of Preferred Stock shall be alike in every particular,
     except that there may be different dates from which dividends, if any,

     if any, may differ from those of any and all other series at any time
     outstanding; and, subject to the provisions of subparagraph 1 of Paragraph
     (c) of this Article FOURTH, the Board of Directors of the Corporation is
     hereby expressly granted authority to fix by resolution or resolutions
     adopted prior to the issuance of any shares of a particular series of
     Preferred Stock, the voting powers and the designations, preferences and
     relative, optional and other special rights, and the qualifications,
     limitations and restrictions of such series, including, but without
     limiting the generality of the foregoing, the following:

          (1)  The distinctive designation of, and the number of shares of
          Preferred Stock which shall constitute such series, which number may
          be increased (except where otherwise provided by the Board of
          Directors) or decreased (but not below the number of shares thereof
          then outstanding) from time to time by like action of the Board of
          Directors;

          (2)  The rate and times at which, and the terms and conditions on
          which, dividends, if any, on Preferred Stock of such series shall be

          dividends to the dividends payable on any other class or classes, or
          series of the same or other class of stock and whether  such dividends
          shall be cumulative or non-cumulative;

          (3)  The right, if any, of the holders of Preferred Stock of such
          series to convert the same into or exchange the same for, shares of
          any other class or classes or of any series of the same or any other
          class or classes of stock of the Corporation and the terms and
          conditions of such conversion or exchange;

          (4)  Whether or not Preferred Stock of such series shall be subject to
          redemption, and the redemption price or prices and the time or times
          at which, and the terms and conditions on which, Preferred Stock of
          such series may be redeemed.

          (5)  The rights, if any, of the holders of Preferred Stock of such
          series upon the voluntary or involuntary liquidation, merger,
          consolidation, distribution or sale of assets, dissolution or winding-
          up, of the Corporation.

          (6)  The terms of the sinking fund or redemption or purchase account,
          if any, to be provided for the Preferred Stock of such series; and

                                       6

          (7)  The voting powers, if any, of the holders of such series of
          Preferred Stock which may, without limiting the generality of the
          foregoing include the right, voting as a series or by itself or
          together with other series of Preferred Stock or all series of
          Preferred Stock as a class, to elect one or more directors of the
          Corporation if there shall have been a default in the payment of
          dividends on any one or more series of Preferred Stock or under such
          circumstances and on such conditions as the Board of Directors may
          determine.

     (c)  (1)  After the requirements with respect to preferential dividends on
     the Preferred Stock (fixed in accordance with the provisions of section (b)
     of this Article FOURTH), if any, shall have been met and after the
     Corporation shall have complied with all the requirements, if any, with
     respect to the setting aside of sums as sinking funds or redemption or
     purchase accounts (fixed in accordance with the provisions of section (b)
     of this Article FOURTH), and subject further to any conditions which may be
     fixed in accordance with the provisions of section (b) of this Article

     entitled to receive such dividends as may be declared from time to time by
     the Board of Directors.

          (2)  After distribution in full of the preferential amount, if any,
          (fixed in accordance with the provisions of section (b) of this
          Article FOURTH), to be distributed to the holders of Preferred Stock
          in the event of voluntary or involuntary liquidation, distribution or
          sale of assets, dissolution or winding-up, of the Corporation, the
          holders of the Common Stock shall be entitled to receive all of the
          remaining assets of the Corporation, tangible and intangible, of
          whatever kind available for distribution to stockholders ratably in
          proportion to the number of shares of Common Stock held by them
          respectively.

          (3)  Except as may otherwise be required by law or by the provisions
          of such resolution or resolutions as may be adopted by the Board of
          Directors pursuant to section (b) of this Article FOURTH, each holder
          of Common Stock shall have one vote in respect of each share of Common
          Stock held on all matters voted upon by the stockholders.

     (d)  No holder of any of the shares of any class or series of stock or of

     of stock or of other securities of the Corporation shall have any
     preemptive right to purchase or subscribe for any unissued stock of any

                                       7
<PAGE>
 
     class or series or any additional shares of any class or series to be
     issued by reason of any increase of the authorized capital stock of the
     Corporation of any class or series, or bonds, certificates of indebtedness,
     debentures or other securities convertible into or exchangeable for stock
     of the Corporation of any class or series, or carrying any right to
     purchase stock of any class or series, but any such unissued stock,
     additional authorized issue of shares of any class or series of stock or
     securities convertible into or exchangeable for stock, or carrying any
     right to purchase stock, may be issued and disposed of pursuant to
     resolution of the Board of Directors to such persons, firms, corporations
     or associations, whether such holders or others, and upon such terms as may
     be deemed advisable by the Board of Directors in the exercise of its sole
     discretion.

     (e)  The relative powers, preferences and rights of each series of
     Preferred Stock in relation to the relative powers, preferences and rights
     of each other series of Preferred Stock shall, in each case, be as fixed
     from time to time by the Board of Directors in the resolution or
     resolutions adopted pursuant to authority granted in section (b) of this
     Article FOURTH and the consent, by class or series vote or otherwise, of
     the holders of such of the series of Preferred Stock as are from time to
     time outstanding shall not be required for the issuance by the Board of
     Directors of any other series of Preferred Stock whether or not the powers,
     preferences and rights of such other series shall be fixed by the Board of
     Directors as senior to, or on a parity with, the powers, preferences and
     rights of such outstanding series, or any of them; provided, however, that
     the Board of Directors may provide in the resolution or resolutions as to
     any series of Preferred Stock adopted pursuant to section (b) of this
     Article FOURTH that the consent of the holders of a majority (or such
     greater proportion as shall be therein fixed) of the outstanding shares of
     such series voting thereon shall be required for the issuance of any or all
     other series of Preferred Stock.

     (f)  Subject to the provisions of section (e), shares of any series of
     Preferred Stock may be issued from time to time as the Board of Directors
     of the Corporation shall determine and on such terms and for such
     consideration as shall be fixed by the Board of Directors.

     (g)  Shares of Common Stock may be issued from time to time as the Board of
     Directors of the Corporation shall determine and on such terms and for such
     consideration as shall be fixed by the Board of Directors.

     (h)  The authorized amount of shares of Common Stock and of Preferred Stock
     may, without a class or series vote, be increased or decreased from time to
     time by the affirmative vote of the holders of a majority of the stock of
     the Corporation entitled to vote thereon.

     FIFTH: - (a)  The business and affairs of the Corporation shall be
     conducted and managed by a Board of Directors.  The number of directors
     constituting the entire Board shall be not less than five nor more than
     twenty-five as fixed from time to time by vote of a majority of the whole
     Board, provided, however, that the number of directors shall not be reduced
     so as to shorten the term of any director at the time in office, and
     provided further, that the number of directors constituting the whole Board
     shall be twenty-four until otherwise fixed by a majority of the whole
     Board.

     (b)  The Board of Directors shall be divided into three classes, as nearly
     equal in number as the then total number of directors constituting the
     whole Board permits, with the term of office of one class expiring each
     year.  At the annual meeting of stockholders in 1982, directors of the
     first class shall be elected to hold office for a term expiring at the next
     succeeding annual meeting, directors of the second class shall be elected
     to hold office for a term expiring at the second succeeding annual meeting
     and directors of the third class shall be elected to hold office for a term
     expiring at the third succeeding annual meeting.  Any vacancies in the
     Board of Directors for any reason, and any newly created directorships
     resulting from any increase in the directors, may be filled by the Board of
     Directors, acting by a majority of the directors then in office, although
     less than a quorum, and any directors so chosen shall hold office until the
     next annual election of directors.  At such election, the stockholders
     shall elect a successor to such director to hold office until the next
     election of the class for which such director shall have been chosen and
     until his successor shall be elected and qualified.  No decrease in the
     number of directors shall shorten the term of any incumbent director.

     (c)  Notwithstanding any other provisions of this Charter or Act of
     Incorporation or the By-Laws of the Corporation (and notwithstanding the
     fact that some lesser percentage may be specified by law, this Charter or
     Act of Incorporation or the By-Laws of the Corporation), any director or
     the entire Board of Directors of the Corporation may be removed at any time
     without cause, but only by the affirmative vote of the holders of two-
     thirds or more of the outstanding shares of capital stock of the
     Corporation entitled to vote generally in the election of directors
     (considered for this purpose as one class) cast at a meeting of the
     stockholders called for

                                       9

     that purpose.

     (d)  Nominations for the election of directors may be made by the Board of
     Directors or by any stockholder entitled to vote for the election of
     directors.  Such nominations shall be made by notice in writing, delivered
     or mailed by first class United States mail, postage prepaid, to the
     Secretary of the Corporation not less than 14 days nor more than 50 days
     prior to any meeting of the stockholders called for the election of
     directors; provided, however, that if less than 21 days' notice of the
     meeting is given to stockholders, such written notice shall be delivered or
     mailed, as prescribed, to the Secretary of the Corporation not later than
     the close of the seventh day following the day on which notice of the
     meeting was mailed to stockholders.  Notice of nominations which are
     proposed by the Board of Directors shall be given by the Chairman on behalf
     of the Board.

     (e)  Each notice under subsection (d) shall set forth (i) the name, age,
     business address and, if known, residence address of each nominee proposed
     in such notice, (ii) the principal occupation or employment of such nominee
     and (iii) the number of shares of stock of the Corporation which are
     beneficially owned by each such nominee.

     (f)  The Chairman of the meeting may, if the facts warrant, determine and
     declare to the meeting that a nomination was not made in accordance with
     the foregoing procedure, and if he should so determine, he shall so declare
     to the meeting and the defective nomination shall be disregarded.

     (g)  No action required to be taken or which may be taken at any annual or
     special meeting of stockholders of the Corporation may be taken without a
     meeting, and the power of stockholders to consent in writing, without a
     meeting, to the taking of any action is specifically denied.

     SIXTH: - The Directors shall choose such officers, agent and servants as
     may be provided in the By-Laws as they may from time to time find necessary
     or proper.

     SEVENTH: - The Corporation hereby created is hereby given the same powers,
     rights and privileges as may be conferred upon corporations organized under
     the Act entitled "An Act Providing a General Corporation Law", approved
     March 10, 1899, as from time to time amended.

     EIGHTH: - This Act shall be deemed and taken to be a private Act.

     NINTH: - This Corporation is to have perpetual existence.

     affairs of the Corporation, and shall have power to authorize the seal of
     the Corporation to be affixed to all papers which may require it.

     THIRTEENTH: - The Board of Directors of the Corporation is expressly
     authorized to make, alter or repeal the By-Laws of the Corporation by a
     vote of the majority of the entire Board.  The stockholders may make, alter
     or repeal any By-Law whether or not adopted by them, provided however, that
     any such additional By-Laws, alterations or repeal may be adopted only by
     the affirmative vote of the holders of two-thirds or more of the
     outstanding shares of capital stock of the Corporation entitled to vote
     generally in the election of directors (considered for this purpose as one
     class).

     FOURTEENTH: - Meetings of the Directors may be held outside of the State of
     Delaware at such places as may be from time to time designated by the
     Board, and the Directors may keep the books of the Company outside of the
     State of Delaware at such places as may be from time to time designated by
     them.

     FIFTEENTH: - (a) In addition to any affirmative vote required by law, and

          Interested Stockholder, or

          (B)  any sale, lease, exchange, mortgage, pledge, transfer or other
