first day of September in each year, commencing March 1, 2012. February 15 and August 15 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 111 and each bond of Series 112 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 February 15 or August 15, as the case may be, next preceding such interest payment date. 

SECTION 3. Execution of Bonds of Series 111 and Bonds of Series 112. The bonds of Series 111 and the bonds of
Series 112 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 111 or any bond of Series 112 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. 

SECTION 4. Medium and Places of Payment of Principal of and Interest on Bonds of Series 111 and Bonds of Series 112;
Transferability and Exchangeability. Both the principal of and interest on the bonds of Series 111 and the bonds of Series 112 shall be payable in any coin or currency of the United

  
 6 

 
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 111 or any bond of Series 112 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 111 and Bonds of Series 112.
The bonds of Series 111 and bonds of Series 112 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 111 or any bond of Series 112 to be conclusively evidenced by the execution thereof on behalf of the Company. Bonds
of Series 111 shall be numbered R-1 and consecutively upwards, and bonds of Series 112 shall be numbered R-1 and consecutively upwards. 
 SECTION 6. Temporary Bonds of Series 111 and Bonds of Series 112. Until definitive bonds of Series 111 or definitive bonds of Series 112 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 111 or temporary registered bonds
without coupons of Series 112. 
 SECTION 7. Redemption of Bonds of Series 111 and Bonds of Series
112. (a) The bonds of Series 111 shall be redeemable, at the option of the Company, as a whole or in part, at any time prior to August 1, 2016 (one month prior to the maturity date of the bonds of Series 111) 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,

 (1) 100% of the principal amount of the bonds of Series 111 to be redeemed, plus accrued and unpaid interest up to but excluding the redemption date, or 

(2) as determined by the Quotation Agent (as hereinafter defined), the sum of the present values of the remaining

year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as hereinafter defined) plus fifteen (15) basis points, plus accrued and unpaid interest up to but excluding the redemption date. 

The bonds of Series 111 shall be redeemable, at the option of the Company, as a whole or in part, at any time on or after August 1, 2016 upon notice

bonds of Series 111 called for redemption. 
 (b) The bonds of Series 112 shall be redeemable, at the option of the Company, as

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 112 to be redeemed, plus accrued and
unpaid interest up to but excluding 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 112 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 (20) basis points, plus accrued and unpaid interest up to
but excluding the redemption date. 
 The bonds of Series 112 shall be redeemable, at the option of the Company, as a whole or in part, at any
time on or after June 1, 2021 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 100% of the principal amount of the bonds of Series 112 to be redeemed, plus accrued and unpaid
interest on those Bonds up to but excluding 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 112 or portions of the bonds of
Series 112 called for redemption. 
 (c) For purposes of the foregoing Sections 7(a) and 7(b), 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 111 or the bonds of Series 112 to be redeemed 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 111 or the bonds of Series 112, as applicable. 
 “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 

  
 8 

 (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 BNP Paribas Securities Corp., Wells Fargo Securities, LLC, and a designee of U.S. Bancorp Investments, Inc., or any of their affiliates, and their respective successors, unless any of them ceases to be a
primary U.S. Government securities dealer in the United States of America (“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 3:30 p.m., New York City time, on the third Business Day preceding that redemption date. 
 (d) In case the Company shall desire to exercise such right to redeem and pay off all or any part of such bonds of Series 111 or bonds of Series 112 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 111 or bonds of Series 112 shall be required under Section 5.03(a) of the Mortgage. 

SECTION 8. Book-Entry Only System. It is intended that the bonds of Series 111 and the bonds of
Series 112 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 111 and the bonds of Series
112 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 111 and the bonds of Series 112 (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 111 and the bonds of Series 112 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 111 or the bonds of Series 112, 

  
 9 

 (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 111 or a bond of Series 112, of any notice with respect to the bonds of Series 111 or the bonds of Series 112, 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 111 or a bond of Series 112, of any amount with respect to principal of, redemption premium, if any, on, or interest on, the bonds of Series 111 or the bonds of Series 112, or 

(iv) any consent given by DTC as registered owner. 
 So long as certificates for the bonds of Series 111 or the bonds of Series 112 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 111 or a bond of Series 112 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, 
 (b) the Company determines that the beneficial owners of the bonds of Series 111 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 111, 
 the bonds of Series 111 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 111 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 111 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. 
 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
112 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 112, 
 the bonds of Series 112 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 112 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 112 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 111 are held by DTC, such bonds
of Series 111 shall, and so long as the bonds of Series 112 are held by DTC, such bonds of Series 112 shall, in each case, 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. Amendment of Provision of Mortgage.
(a) Section 15.06 of the Mortgage shall be amended and restated to read in its entirety as follows: 

SECTION 15.06. The Trustee and any successor to the Trustee may resign and be discharged from the trusts created by this
Mortgage by giving notice thereof in writing to the 

  
 11 

 
Company, specifying the date when such resignation shall take effect, and by giving notice thereof to the bondholders in the manner and to the extent provided under Section 15.10(c), and by
publishing such notice at least once a week for three successive calendar weeks (the first such publication to be not less than thirty days nor more than sixty days prior to the effective date of such resignation) in one authorized newspaper in the
City of Chicago, State of Illinois, and in one authorized newspaper in the Borough of Manhattan, The City of New York, State of New York. Subject to the provisions of Sections 15.04 and 15.05, such resignation shall take effect on the date specified
in such notice unless previously a successor Trustee shall have been appointed as hereinafter provided, in which event such resignation shall take effect upon the appointment of such successor Trustee. The Co-Trustee and any successor to the
Co-Trustee may resign at any time and be discharged from the trusts hereby created by giving the Trustee and the Company notice in writing of such resignation, specifying a date when such resignation shall take effect, which shall be at least thirty
days after the giving of such notice. Such resignation shall, subject to the provisions of Sections 15.04 and 15.05, take effect on the date specified in such notice unless previously a successor trustee shall have been appointed as hereinafter
provided, in which event such resignation shall take effect immediately upon the appointment of such a successor trustee. 
 Either of the Trustees or any successor trustee may be removed at any time by the holders of a majority in principal amount of the bonds issued hereunder and at the time outstanding, upon payment to the
trustee so removed of all moneys then due to it or him hereunder, by an instrument or concurrent instruments in writing, signed in duplicate by such holders. One copy shall be filed with the Company and the other with the trustee so removed.

 The Co-Trustee and any successor to the Co-Trustee may be removed at any time by an instrument in writing
signed in duplicate by the Trustee, one copy of which shall be filed with the Company and the other delivered to the Co-Trustee so removed. 
 In case at any time either of the Trustees or any successor trustee shall resign, die, be dissolved or be removed or otherwise shall become disqualified to act or incapable of acting, or in case control
of the Trustee or of any successor trustee, or of its officers shall be taken over by any public officer or officers, a successor trustee may be appointed by the holders of a majority in principal amount of the bonds issued hereunder and at the time
outstanding by an instrument or concurrent instruments in writing signed in duplicate by such holders, and filed, one copy with the retiring trustee and the other with the successor trustee, notification thereof being given to the Company by such
successor trustee; but until a successor trustee shall be so appointed by the bondholders as herein authorized, the Company, by an instrument in writing, executed by order of the Board of Directors, shall in any such case appoint a successor to the
Trustee and the Trustee shall, by an instrument in writing in any such case, appoint a successor to the Co-Trustee. Every such successor to the Trustee so appointed by the bondholders, by a court of competent jurisdiction or by the Company shall be
a bank or trust company in good standing organized and doing business under the laws of the United States or of any State, having an office in the United States of America, and (a) which shall be a corporation having a combined capital and
surplus of not less than $5,000,000, (b) which shall be authorized under the laws of the jurisdiction of incorporation to exercise corporate trust powers, and (c) which shall be subject to supervision or examination by a Federal or State
authority. If such successor Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of such supervising or examining authority, the combined capital and surplus of such successor Trustee shall be deemed to
be its combined capital and surplus as set forth in its most recent report of condition so published. Every such successor trustee appointed by the bondholders or by the Trustee in succession to the Co-Trustee shall always be an individual, a
citizen of the United States of America, unless otherwise required by law. 

  
 12 

 Anything hereinabove to the contrary notwithstanding, in case at any time
the Co-Trustee, or any successor thereto, shall die, become incapable of acting, resign or be removed, all the estates, properties, rights, powers, trusts, duties and obligations of the Trustees hereunder shall, to the extent permitted by law, vest
in and be exercised by the Trustee, without the appointment of a successor Co-Trustee. 
 If in a proper case no
appointment of a successor to the Trustee or of a successor to the Co-Trustee shall be made pursuant to the foregoing provisions of this Article XV within six months after a vacancy shall have occurred in the office of trustee, the holder of any
bond or the retiring Trustee or Co-Trustee may apply to any court, State or Federal having jurisdiction to appoint a successor trustee, and such court may thereupon, after such notice, if any, as such court may deem proper and prescribe, appoint a
successor to the Trustee or to the Co-Trustee, as the case may be. 
 (b) The holders of the bonds of Series 111 and the bonds
of Series 112 shall be deemed to have approved the foregoing amendment; however, the foregoing amendment shall not become effective until such time as it shall have received the requisite approvals under the provisions of the Mortgage. 

SECTION 12. 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 August 22, 2011, 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 111 and the bonds of Series 112).

 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 Mellon Trust Company of Illinois, as Trustee under the Mortgage, has caused this Supplemental Indenture to be executed
in its name by one of its Vice Presidents, and attested 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.
