Holdings, Inc., a Delaware corporation (the “Company”) and the persons listed on Schedule I
hereto (each a “Stockholder” and, collectively, the “Stockholders”).

RECITALS

     WHEREAS, concurrently with the execution and delivery of this Agreement, the Company and
Northwest Suburban Bancorp., Inc., a Delaware corporation (the “Seller”), are entering into an
Agreement and Plan of Merger (the “Merger Agreement”), which provides, among other things, for the
merger of the Seller with and into the Company (the “Merger”), all on the terms and subject to the
conditions set forth in the Merger Agreement; and

     WHEREAS, as an inducement and a condition to entering into the Merger Agreement, the Company
has required that the Stockholders agree, and each Stockholder has agreed, to enter into this
Agreement;

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set
forth herein, the parties hereto agree as follows:

     1. Definitions. Terms used and not defined herein, but defined in the Merger
Agreement, shall have the respective meanings ascribed to them in the Merger Agreement.

     2. Voting.

     (a) Each Stockholder shall, at any meeting of the stockholders of the Seller, however
called, or in connection with any written consent of the stockholders of the Seller, vote
(or cause to be voted) all shares of Seller Common Stock (the “Shares”) then held of record
or beneficially owned by such Stockholder (to the extent the Stockholder has the sole right
to vote or direct the voting of such Shares) and use his reasonable best efforts to vote (or
cause to be voted) all Shares then held of record or beneficially owned by such Stockholder
(to the extent such Stockholder has the shared right to vote or direct the voting of such
Shares) (i) in favor of the Merger, the execution and delivery by the Seller of the Merger
Agreement and the approval of the terms thereof and each of the other actions contemplated
by the Merger Agreement and this Agreement and any actions required in furtherance thereof
and hereof, and (ii) against any proposal relating to an Acquisition Proposal and against
any action or agreement that would result in a breach in any respect of any covenant,
representation or warranty or any other obligation or agreement of the Seller under the
Merger Agreement or which would result in any of the conditions set forth in Article VII of
the Merger Agreement not being fulfilled.

     (b) Each Stockholder hereby covenants and agrees that, except as contemplated by this
Agreement and the Merger Agreement, such Stockholder shall not (i) offer to transfer (which
term shall include, without limitation, any sale, tender, gift,

 

 

pledge, assignment or other
disposition), transfer or consent to any transfer of, any or all of the Shares beneficially
owned by such Stockholder (to the extent the Stockholder has the right to dispose of or
direct the disposition of such Shares) or any interest therein, except for transfers by will
or by operation of law (in which case this Agreement shall bind the transferee) without the
prior written consent of the Company, such consent not to be unreasonably withheld (it being
understood that the Company may decline to consent to any such transfer if the Person
acquiring such Shares does not agree to take such Shares subject to the terms of this
Agreement but will consent to any such transfer if the Person acquiring such Shares agrees
to take such Shares subject to the terms of this Agreement), (ii) enter into any option or
other Contract with respect to any transfer of any or all of such Shares or any interest
therein except as permitted in clause (i), or (iii) subject to Section 6 hereof, take any
other action that would make any representation or warranty of such Stockholder contained
herein untrue or incorrect in any material respect or in any way restrict, limit or
interfere in any material respect with the performance of such Stockholder’s obligations
hereunder or the transactions contemplated hereby or by the Merger Agreement.

     (c) Subject to Section 6 hereof, each Stockholder hereby agrees that such Stockholder
(i) shall not, directly or indirectly, encourage, solicit, initiate or participate in any
way in any discussions or negotiations with, or provide any information to, or afford any
access to the properties, books or records of the Seller or any Seller Subsidiaries to, or
otherwise take any other action to assist or facilitate, any Person or group (other than the
Company or any affiliate or associate of the Company) concerning any Acquisition Proposal,
(ii) upon execution of this Agreement, will immediately cease any existing activities,
discussions or negotiations conducted heretofore with respect to any Acquisition Proposal,
and (iii) will immediately communicate to the Company the terms of any Acquisition Proposal
(or any discussion, negotiation or inquiry with respect thereto) and the identity of the
Person making such Acquisition Proposal or inquiry which such Stockholder may receive.

     (d) Subject to the terms and conditions of this Agreement, each of the parties hereto
agrees to use all reasonable efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, all things necessary, proper or advisable under applicable Laws to
consummate and make effective the transactions contemplated by this Agreement and the Merger
Agreement. Each party shall promptly consult with the other and provide any necessary
information and material with respect to all filings made by such party with any
Governmental Authority in connection with this Agreement and the transactions contemplated
hereby and by the Merger Agreement.

     (e) To the fullest extent permitted by applicable Law, each Stockholder hereby waives
any rights of appraisal or rights to dissent from the Merger that such Stockholder may have.

     3. Representations and Warranties of Each Stockholder. Each Stockholder hereby represents and warrants, severally and not jointly, to the Company
as follows:

2

 

     (a) Such Stockholder is the record and beneficial owner of the Shares set forth
opposite such Stockholder’s name on Schedule I. Such Shares constitute all of the
shares owned of record and beneficially owned by such Stockholder on the date hereof. Such
Stockholder has sole voting power and sole power to issue instructions with respect to the
matters set forth in Section 2 hereof, sole power of disposition, sole power to demand and
waive appraisal rights and sole power to agree to all of the matters set forth in this
Agreement, in each case with respect to all of such Shares listed in Schedule I with
no limitations, qualifications or restrictions on such rights, subject to applicable
securities laws and the terms of this Agreement.

     (b) Such Stockholder has the power and authority to enter into and perform all of such
Stockholder’s obligations under this Agreement. This Agreement has been duly and validly
executed and delivered by such Stockholder and constitutes a legal, valid and binding
agreement of such Stockholder, enforceable against such Stockholder in accordance with its
terms, except in each case as enforcement may be limited by general principles of equity,
whether applied in a court of law or a court of equity, and by bankruptcy, insolvency and
similar Laws affecting creditor’s rights and remedies generally. There is no beneficiary or
holder of a voting trust certificate or other interest of any trust of which such
Stockholder is a trustee, or any party to any other agreement or arrangement, whose consent
is required for the execution and delivery of this Agreement or the consummation by such
Stockholder of the transactions contemplated thereby.

     (c) (i) To the Knowledge of such Stockholder, no filing with, and no permit,
authorization, consent or approval of, any Governmental Authority is necessary for the
execution and delivery of this Agreement by such Stockholder, the consummation by such
Stockholder of the transactions contemplated hereby and the compliance by such Stockholder
with the provisions hereof, and (ii) none of the execution and delivery of this Agreement by
such Stockholder, the consummation by such Stockholder of the transactions contemplated
hereby or compliance by such Stockholder with any of the provisions hereof, except in cases
in which any conflict, breach, default or violation described below would not interfere with
the ability of such Stockholder to perform such Stockholder’s obligations hereunder, shall
(A) conflict with or result in any breach of any organizational documents applicable to such
Stockholder, (B) result in a violation or breach of, or constitute (with or without notice
or lapse of time or both) a default (or give rise to any third party right of termination,
cancellation, modification or acceleration) under, any of the terms, conditions or
provisions of any note, loan agreement, bond, mortgage, indenture, license or other Contract
of any kind, including, without limitation, any voting agreement, proxy arrangement, pledge
agreement, stockholders agreement or voting trust, to which such Stockholder is a party or
by which such Stockholder or any of such Stockholder’s properties or assets may be bound, or
(C) violate any Order or Law applicable to such Stockholder or any of such Stockholder’s
properties or assets.

     (d) Except as permitted by this Agreement, the Shares beneficially owned by such
Stockholder and the certificates representing such Shares are now, and at all times
during the term hereof will be, held by such Stockholder, or by a nominee or custodian
for the benefit of such Stockholder, free and clear of all Liens, proxies, voting trusts or
agreements, understandings or arrangements or any other rights whatsoever, except for

3

 

any such Liens or proxies arising hereunder and except for Liens created prior to the date
hereof with respect to which the obligations secured thereby are not currently in default.

     4. Stop Transfer. Each Stockholder shall request that the Seller not register the
transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any
of the Shares beneficially owned by such Stockholder, unless such transfer is made in compliance
with this Agreement.

     5. Termination. This Agreement shall terminate, and none of the Stockholders or the
Company shall have any further rights or obligations hereunder, upon the earliest of (a) the
Effective Time or (b) the termination of the Merger Agreement. The representations and warranties
of the Stockholders shall not survive the termination of this Agreement.

     6. No Limitation. Notwithstanding any other provision hereof, the parties acknowledge
that each Stockholder is entering into this Agreement solely in his or her capacity as a
Stockholder, and nothing in this Agreement shall be construed to prohibit a Stockholder, or any
officer or affiliate of a Stockholder who is or has been designated a member of the Board of
Directors of the Seller, from taking any action solely in his or her capacity as a member of the
Board of Directors of the Seller or from exercising his or her fiduciary duties as a member of such
Board of Directors to the extent specifically permitted by the Merger Agreement.

     7. Miscellaneous.

     (a) This Agreement constitutes the entire agreement between the parties with respect to
the subject matter hereof and supersedes all other prior agreements and understandings, both
written and oral, between the parties with respect to the subject matter hereof.

     (b) This Agreement shall not be assigned by operation of Law or otherwise without the
prior written consent of each Stockholder (in the case of any assignment by the Company) or
the Company (in the case of an assignment by a Stockholder), provided that the Company may
assign its rights and obligations hereunder to any Company Subsidiary, but no such
assignment shall relieve the Company of its obligations hereunder.

     (c) Without limiting any other rights the Company may have hereunder in respect of any
transfer of Shares, each Stockholder agrees that this Agreement and the obligations
hereunder shall attach to the Shares owned of record and beneficially owned
by such Stockholder and shall be binding upon any Person to which legal or beneficial
ownership of such Shares shall pass, whether by operation of Law or otherwise, including,
without limitation, such Stockholder’s heirs, guardians, administrators or successors.

     (d) This Agreement may not be amended, changed, supplemented or otherwise modified with
respect to a Stockholder except by an instrument in writing signed on behalf of such
Stockholder and the Company.

     (f) Whenever possible, each provision or portion of any provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable Law but if

     (h) The failure of any party hereto to exercise any right, power or remedy provided

     (i) This Agreement shall be binding upon and inure solely to the benefit of each party

6

 

Agreement or any transaction contemplated by this Agreement in any court other than any such

venue of any Proceeding arising out of this Agreement or the transactions contemplated
hereby in the courts of the State of Illinois located in the County of Cook or in any
Federal court located in the Northern District of Illinois, and hereby further irrevocably
and unconditionally waive and agree not to plead or claim in any such court that any such

     (l) The descriptive headings used herein are inserted for convenience of reference only
and are not intended to be part of or to affect the meaning or interpretation of this
Agreement.

and the same agreement.

     (n) All representations, warranties, covenants, agreements, liabilities and obligations

     WHEREAS, the Mortgage provides for the issuance from time to time thereunder, in series, of

     WHEREAS, pursuant to the February 22, 2006 Supplemental Indenture, the Company issued “bonds
of Series 103” (as defined in the February 22, 2006 Supplemental Indenture) under and pursuant to

(including the February 22, 2006 Supplemental Indenture) in the aggregate principal amount of Three

governed by the terms, provisions and conditions set forth in the February 22, 2006 Supplemental
Indenture; and

     WHEREAS, the Company desires to execute and deliver this Supplemental Indenture for purposes
of providing notice of the issuance of the Additional bonds of Series 103 under and pursuant to the
Mortgage and confirming that such Additional bonds of Series 103 are secured by the lien of the
Mortgage, as further provided herein; and

-11-

 

     WHEREAS, the Company is legally empowered and has been duly authorized by the necessary
corporate action and by order of the Illinois Commerce Commission to make, execute and deliver this
Supplemental Indenture, and to issue the Additional bonds of Series 103, and all acts and things
whatsoever necessary to make this Supplemental Indenture, when executed and delivered by the
Company and the Trustees, a valid, binding and legal instrument, and to make the Additional bonds
of Series 103, when authenticated by the Trustee and issued as in the Mortgage and in this
Supplemental Indenture provided, the valid, binding and legal obligations of the Company, entitled
in all respects to the security of the Mortgage, as amended and supplemented, have been done and
performed;

     NOW, THEREFORE, in consideration of the premises and of the sum of one dollar duly paid by the
Trustees to the Company, and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties hereto do hereby agree as follows:

     SECTION 1. Designation and Issuance of Additional Bonds of Series 103. The Additional bonds
of Series 103 shall, as provided in the February 22, 2006 Supplemental Indenture, be designated as
additional “First Mortgage 5.90% Bonds, Series 103.” The Additional bonds of Series 103 shall, for
all purposes, constitute “bonds of Series 103” for purposes of the Mortgage, shall be governed by
each and all of the terms, provisions and conditions set forth in the February 22, 2006
Supplemental Indenture, and shall be secured by the Mortgage. The parties confirm that, subject to
the provisions of the Mortgage, the bonds of Series 103 shall be issuable without limitation as to
the aggregate principal amount thereof.

     SECTION 2. Confirmation of Lien. The Company, for the equal and proportionate benefit and
security of the holders of all bonds at any time issued under the Mortgage, hereby confirms the
lien of the Mortgage upon, and hereby grants, bargains, sells, transfers, assigns, pledges,
mortgages, warrants and conveys unto the Trustees, all property of the Company and all property
hereafter acquired by the Company, other than (in each case) property which, by virtue of any of
the provisions of the Mortgage, is excluded from such lien, and hereby confirms the title of the
Trustees (as set forth in the Mortgage) in and to all such property. Without in any way limiting
or restricting the generality of the foregoing, there is specifically included within the
confirmation of lien and title hereinabove expressed the property of the Company legally described
on Exhibit B attached hereto and made a part hereof.

-12-

 

     SECTION 3. Miscellaneous. The terms and conditions of this Supplemental Indenture shall be
deemed to be a part of the terms and conditions of the Mortgage for
any and all purposes. The Mortgage, as supplemented by said indentures supplemental thereto
dated subsequent to August 1, 1944 and referred to in the recitals of this Supplemental Indenture,
and as further supplemented by this Supplemental Indenture, is in all respects hereby ratified and
confirmed.

     This Supplemental Indenture shall bind and, subject to the provisions of Article XIV of the
Mortgage, inure to the benefit of the respective successors and assigns of the parties hereto.

     Although this Supplemental Indenture is dated as of March 1, 2007, it shall be effective only
from and after the actual time of its execution and delivery by the Company and the Trustees on the
date indicated by their respective acknowledgments hereto annexed.

     Notwithstanding anything to the contrary contained in the Mortgage, the maximum amount of
indebtedness secured by the Mortgage shall not exceed 200% of the aggregate stated principal amount
of the bonds of each series presently outstanding under, and secured by, the Mortgage, as set forth
in the Recitals to this Supplemental Indenture, except to the extent such maximum amount may be
adjusted by a subsequent recorded supplemental indenture (which adjustment, and the corresponding
supplemental indenture, shall not require the consent or approval of the holders of any bonds then
outstanding under the Mortgage, including the holders of the bonds of Series 103).

     This Supplemental Indenture may be simultaneously executed in any number of counterparts, and
all such counterparts executed and delivered, each as an original, shall constitute but one and the
same instrument.

-13-

 

     IN WITNESS WHEREOF, Commonwealth Edison Company has caused this Supplemental Indenture to
be executed in its name by its Senior Vice President, Chief Financial Officer and Treasurer, and
attested by its Secretary, and BNY Midwest Trust Company, as Trustee under the Mortgage, has caused

     WHEREAS, the Mortgage provides for the issuance from time to time thereunder, in series,
of bonds of the Company for the purposes and subject to the limitations therein specified; and

     WHEREAS, the Company desires, by this Supplemental Indenture, to create an additional series
of bonds to be issuable under the Mortgage, such bonds to be designated “First Mortgage 5.90%
Bonds, Series 103” (hereinafter called the “bonds of Series 103”) and the terms and provisions to
be contained in the bonds of Series 103 or to be otherwise applicable thereto to be as set forth in this
Supplemental Indenture; and

     WHEREAS, the bonds of Series 103 and the Trustee’s certificate to be endorsed thereon shall be
substantially in the form of the General Form of Registered Bond Without Coupons and the form of
the General Form of Trustee’s Certificate set forth in Section 3.05 of the Supplemental Indenture
dated August 1, 1944 to the Mortgage with such appropriate insertions, omissions and variations in
order to express the designation, date, maturity date, annual interest rate, record dates for, and
dates of, payment of interest, denominations, terms of redemption and redemption prices, and other
terms and characteristics authorized or permitted by the Mortgage or not inconsistent therewith;
and

     WHEREAS, the Company is legally empowered and has been duly authorized by the necessary
corporate action and by orders of the Illinois Commerce Commission to make, execute and deliver
this Supplemental Indenture, and to create, as an additional series of bonds of the Company, the
bonds of Series 103, and all acts and things whatsoever necessary to make this Supplemental
Indenture, when executed and delivered by the Company and the Trustees, a valid, binding and legal
instrument, and to

6

 

make the bonds of Series 103, when authenticated by the Trustee and issued as in the Mortgage
and in this Supplemental Indenture provided, the valid, binding and legal obligations of the
Company, entitled in all respects to the security of the Mortgage, as amended and supplemented,
have been done and performed;

     NOW, THEREFORE, in consideration of the premises and of the sum of one dollar duly paid by the
Trustees to the Company, and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties hereto do hereby agree as follows:

     SECTION 1. Designation and Issuance of Bonds of Series 103. The bonds of Series 103 shall,
as hereinbefore recited, be designated as the Company’s “First Mortgage 5.90% Bonds, Series 103.”
Subject to the provisions of the Mortgage, the bonds of Series 103 shall be issuable without
limitation as to the aggregate principal amount thereof.

     SECTION 2. Form, Date, Maturity Date, Interest Rate and Interest Payment Dates of Bonds of
Series 103. (a) The definitive bonds of Series 103 shall be in engraved, lithographed, printed or
typewritten form and shall be registered bonds without coupons; and such bonds and the Trustee’s
certificate to be endorsed thereon shall be substantially in the forms hereinbefore recited,
respectively. The bonds of Series 103 shall be dated as provided in Section 3.01 of the Mortgage,
as amended by Supplemental Indenture dated April 1, 1967.

     (b) The bonds of Series 103 shall mature on March 15, 2036.

     (c) The bonds of Series 103 shall bear interest at the rate of 5.90% per annum until the
principal thereof shall be paid.

     (d) Interest on the bonds of Series 103 shall be payable semi-annually on the fifteenth day of
March and the fifteenth day of September in each year, commencing September 15, 2006. March 1 and
September 1 in each year are hereby established as record dates for the payment of interest payable
on the next succeeding interest payment dates, respectively. The interest on each bond of Series
103 so payable on any interest payment date shall, subject to the exceptions provided in Section
3.01 of the Mortgage, as amended by said Supplemental Indenture dated April 1, 1967, be paid to the
person in whose name such bond is registered at the close of business on the March 1 or September
1, as the case may be, next preceding such interest payment date.

     SECTION 3. Execution of Bonds of Series 103. The bonds of Series 103 shall be executed on
behalf of the Company by its President or one of its Vice Presidents, manually or by facsimile
signature, and shall have its corporate seal affixed thereto or a facsimile of such seal imprinted
thereon, attested by its Secretary or one of its Assistant Secretaries, manually or by facsimile
signature, all as may be provided by resolution of the Board of Directors of the Company. In case
any officer or officers whose signature or signatures, manual or facsimile, shall appear upon any
bond of Series 103 shall cease to be such officer or officers before such bond shall have been
actually authenticated and delivered, such bond nevertheless may be issued, authenticated and
delivered with the same force and effect as though the person or persons whose signature or
signatures, manual or facsimile, appear thereon had not ceased to be such officer or officers of
the Company.

7

 

     SECTION 4. Medium and Places of Payment of Principal of and Interest on Bonds of Series 103;
Transferability and Exchangeability. Both the principal of and interest on the bonds of Series 103
shall be payable in any coin or currency of the United States of America which at the time of
payment is
legal tender for the payment of public and private debts, and both such principal and interest
shall be payable at the office or agency of the Company in the City of Chicago, State of Illinois,
or, at the option of the registered owner, at the office or agency of the Company in the Borough of
Manhattan, The City of New York, State of New York, and such bonds shall be transferable and
exchangeable, in the manner provided in Sections 3.09 and 3.10 of the Mortgage, at said office or
agency. No charge shall be made by the Company to the registered owner of any bond of Series 103
for the transfer of such bond or for the exchange thereof for bonds of other authorized
denominations, except, in the case of transfer, a charge sufficient to reimburse the Company for
any stamp or other tax or governmental charge required to be paid by the Company or the Trustee.

     SECTION 5. Denominations and Numbering of Bonds of Series 103. The bonds of Series 103 shall
be issued in the denomination of $1,000 and in such multiples of $1,000 as shall from time to time
hereafter be determined and authorized by the Board of Directors of the Company or by any officer
or officers of the Company authorized to make such determination, the authorization of the
denomination of any bond of Series 103 to be conclusively evidenced by the execution thereof on
behalf of the Company. Bonds of Series 103 shall be numbered R-1 and consecutively upwards.

     SECTION 6. Temporary Bonds of Series 103. Until definitive bonds of Series 103 are ready for
delivery, there may be authenticated and issued in lieu of any thereof and subject to all of the
provisions, limitations and conditions set forth in Section 3.11 of the Mortgage, temporary
registered bonds without coupons of Series 103.

     SECTION 7. Redemption of Bonds of Series 103. (a) The bonds of Series 103 shall be
redeemable, at the option of the Company, as a whole or in part, at any time upon notice sent by
the Company through the mail, postage prepaid, at least thirty (30) days and not more than
forty-five (45) days prior to the date fixed for redemption, to the registered holder of each bond
to be redeemed in whole or in part, addressed to such holder at his address appearing upon the
registration books, at a redemption price equal to the greater of

     (1) 100% of the principal amount of the bonds of Series 103 to be redeemed, plus
accrued interest to the redemption date, or

     (2) as determined by the Quotation Agent (as hereinafter defined), the sum of the
present values of the remaining scheduled payments of principal and interest on the bonds of
Series 103 to be redeemed (not including any portion of payments of interest accrued as of
the redemption date) discounted to the redemption date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as
hereinafter defined) plus twenty-five (25) basis points, plus accrued interest to the
redemption date.

Unless the Company defaults in payment of the redemption price, on and after the redemption date,
interest will cease to accrue on the bonds of Series 103 or portions of the bonds of Series 103
called for redemption.

8

 

     (b) For purposes of the foregoing Section 7(a), the following terms shall have the respective
meanings set forth below:

     “Adjusted Treasury Rate” means, with respect to any redemption date, the rate per year
equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue,
assuming a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for the redemption date.

     “Business Day” means any day that is not a day on which banking institutions in New
York City are authorized or required by law or regulation to close.

     “Comparable Treasury Issue” means the United States Treasury security selected by the
Quotation Agent as having a maturity comparable to the remaining term of the bonds of Series
103 that would be used, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the bonds of Series 103.

     “Comparable Treasury Price” means, with respect to any redemption date:

     (i) the average of the Reference Treasury Dealer Quotations for that redemption
date, after excluding the highest and lowest of the Reference Treasury Dealer
Quotations; or

     (ii) if the Trustee obtains fewer than three Reference Treasury Dealer
Quotations, the average of all Reference Treasury Dealer Quotations so received.

     “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

     “Reference Treasury Dealer” means (1) each of Lehman Brothers Inc., J.P. Morgan
Securities Inc. and Morgan Stanley & Co. Incorporated and their respective successors,
unless any of them ceases to be a primary U.S. Government securities dealer in New York City
(a “Primary Treasury Dealer”), in which case the Company shall substitute another Primary
Treasury Dealer; and (2) any other Primary Treasury Dealer selected by the Company.

     “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any redemption date, the average, as determined by the Trustee, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at
5:00 p.m., New York City time, on the third Business Day preceding that redemption date.

     (c) In case the Company shall desire to exercise such right to redeem and pay off all or any
part of such bonds of Series 103 as hereinbefore provided, it shall comply with all the terms and
provisions of Article V of the Mortgage applicable thereto, and such redemption shall be made under
and subject to the terms and provisions of Article V and in the manner and with the effect therein
provided, but at the time or times and upon mailing of notice, all as hereinbefore set forth in
this Section 7. No publication of notice of any redemption of any bonds of Series 103 shall be
required under Section 5.03(a) of the Mortgage.

9

 

     SECTION 8. Book-Entry Only System. It is intended that the bonds of Series 103 be registered
so as to participate in the securities depository system (the “DTC System”) with The Depository
Trust Company (“DTC”), as set forth herein. The bonds of Series 103 shall be initially issued in
the form of a fully registered bond or bonds in the name of Cede & Co., or any successor thereto,
as nominee for DTC. The Company and the Trustees are authorized to execute and deliver such
letters to or agreements with DTC as shall be necessary to effectuate the DTC System, including the
Letter of Representations from
the Company and the Trustees to DTC relating to the bonds of Series 103 (the “Representation
Letter”). In the event of any conflict between the terms of the Representation Letter and the
Mortgage, the terms of the Mortgage shall control. DTC may exercise the rights of a bondholder only
in accordance with the terms hereof applicable to the exercise of such rights.

     With respect to bonds of Series 103 registered in the name of DTC or its nominee, the Company
and the Trustees shall have no responsibility or obligation to any broker-dealer, bank or other
financial institution for which DTC holds such bonds from time to time as securities depository
(each such broker-dealer, bank or other financial institution being referred to herein as a
“Depository Participant”) or to any person on behalf of whom such a Depository Participant holds an
interest in such bonds (each such person being herein referred to as an “Indirect Participant”).
Without limiting the immediately preceding sentence, the Company and the Trustees shall have no
responsibility or obligation with respect to:

     (i) the accuracy of the records of DTC, its nominee or any Depository Participant with
respect to any ownership interest in the bonds of Series 103,

     (ii) the delivery to any Depository Participant or any Indirect Participant or any
other person, other than a registered owner of a bond of Series 103, of any notice with
respect to the bonds of Series 103, including any notice of redemption,

     (iii) the payment to any Depository Participant or Indirect Participant or any other
person, other than a registered owner of a bond of Series 103, of any amount with respect to
principal of, redemption premium, if any, on, or interest on, the bonds of Series 103, or

     (iv) any consent given by DTC as registered owner.

So long as certificates for the bonds of Series 103 are not issued as hereinafter provided, the
Company and the Trustees may treat DTC or any successor securities depository as, and deem DTC or
any successor securities depository to be, the absolute owner of such bonds for all purposes
whatsoever, including, without limitation, (1) the payment of principal and interest on such bonds,
(2) giving notice of matters (including redemption) with respect to such bonds and (3) registering
transfers with respect to such bonds. While a bond of Series 103 is in the DTC System, no person
other than DTC or its nominee shall receive a certificate with respect to such bond.

     In the event that:

     (a) DTC notifies the Company that it is unwilling or unable to continue as depositary
or if DTC ceases to be a clearing agency registered under applicable law and a successor
depositary is not appointed by the Company within 90 days,

10

 

     (b) the Company determines that the beneficial owners of the bonds of Series 103 should
be able to obtain certificated bonds and so notifies the Trustees in writing or

     (c) there shall have occurred and be continuing a completed default or any event which
after notice or lapse of time or both would be a completed default with respect to the bonds
of Series 103,

the bonds of Series 103 shall no longer be restricted to being registered in the name of DTC or its
nominee. In the case of clause (a) of the preceding sentence, the Company may determine that the
bonds of Series 103 shall be registered in the name of and deposited with a successor depository
operating a securities depository system, as may be acceptable to the Company and the Trustees, or
such depository’s agent or designee, and if the Company does not appoint a successor securities
depository system within 90 days, then the bonds may be registered in whatever name or names
registered owners of bonds transferring or exchanging such bonds shall designate, in accordance
with the provisions hereof.

     Notwithstanding any other provision of the Mortgage to the contrary, so long as any bond of
Series 103 is registered in the name of DTC or its nominee, all payments with respect to principal
of and interest on such bond and all notices with respect to such bond shall be made and given,
respectively, in the manner provided in the Representation Letter.

     SECTION 9. Legends. So long as the bonds of Series 103 are held by DTC, such bonds of Series
103 shall bear the following legend:

     Unless this bond is presented by an authorized representative of the Depository Trust
Company, a New York corporation (“DTC”), to the Company or its agent for registration of
transfer, exchange or payment, and any bond issued is registered in the name of Cede & Co.
or in such other name as is requested by an authorized representative of DTC (and any
payment is made to Cede & Co. or to such other entity as is requested by an authorized
representative of DTC), any transfer, pledge or other use hereof for value or otherwise by a
person is wrongful inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

     SECTION 10. Confirmation of Lien. The Company, for the equal and proportionate benefit and
security of the holders of all bonds at any time issued under the Mortgage, hereby confirms the
lien of the Mortgage upon, and hereby grants, bargains, sells, transfers, assigns, pledges,
mortgages, warrants and conveys unto the Trustees, all property of the Company and all property
hereafter acquired by the Company, other than (in each case) property which, by virtue of any of
the provisions of the Mortgage, is excluded from such lien, and hereby confirms the title of the
Trustees (as set forth in the Mortgage) in and to all such property. Without in any way limiting
or restricting the generality of the foregoing, there is specifically included within the
confirmation of lien and title hereinabove expressed the property of the Company legally described
on Exhibit A attached hereto and made a part hereof.

     SECTION 11. Miscellaneous. The terms and conditions of this Supplemental Indenture shall be
deemed to be a part of the terms and conditions of the Mortgage for any and all purposes. The
Mortgage, as supplemented by said indentures supplemental thereto dated subsequent to August 1,
1944 and referred to in the recitals of this Supplemental Indenture, and as further supplemented by
this Supplemental Indenture, is in all respects hereby ratified and confirmed.

11

 

     This Supplemental Indenture shall bind and, subject to the provisions of Article XIV of the
Mortgage, inure to the benefit of the respective successors and assigns of the parties hereto.

     Although this Supplemental Indenture is dated as of February 22, 2006, it shall be effective
only from and after the actual time of its execution and delivery by the Company and the Trustees
on the date indicated by their respective acknowledgments hereto annexed.

     Notwithstanding anything to the contrary contained in the Mortgage, the maximum amount of
indebtedness secured by the Mortgage shall not exceed 200% of the aggregate stated principal amount
of the bonds of each series presently outstanding under, and secured by, the Mortgage, as set forth
in the Recitals to this Supplemental Indenture, except to the extent such maximum amount may be
adjusted by a subsequent recorded supplemental indenture (which adjustment, and the corresponding
supplemental indenture, shall not require the consent or approval of the holders of any bonds then
outstanding under the Mortgage, including the holders of the bonds of Series 103).

     This Supplemental Indenture may be simultaneously executed in any number of counterparts, and
all such counterparts executed and delivered, each as an original, shall constitute but one and the
same instrument.

12

 

     IN WITNESS WHEREOF, Commonwealth Edison Company has caused this Supplemental Indenture to
be executed in its name by its Senior Vice President, Chief Financial Officer and Treasurer, and
attested by its Secretary, and BNY Midwest Trust Company, as Trustee under the Mortgage, has caused

by one of its Vice Presidents, and D.G. Donovan, as Co-Trustee under the Mortgage, has hereunto
affixed his signature, all as of the day and year first above written.
