ARTICLE

REPRESENTATIONS
AND WARRANTIES OF NNA

 

To induce Company to
enter into this Agreement and the transactions contemplated hereby, NNA represents and warrants to Company as of the Effective
Date as follows:

 

5.1Securities Law
Matters.

 

(a)NNA is acquiring
the Exchange Shares for its own account, for investment and not with a view to, or for sale in connection with, the distribution
thereof within the meaning of the Securities Act (it being understood that except as otherwise provided in this Agreement and the
other Transaction Documents to which it is a party, NNA does not agree to hold the Securities for any minimum or other specific
term and reserves the right to dispose of the Exchange Shares at any time in accordance with the Securities Act and state securities
Laws applicable to such disposition).

 

    4 

     

    

 

(b)NNA is an “accredited
investor,” as that term is as defined in Rule 501(a) of Regulation D under the Securities Act. NNA has sufficient knowledge
and experience in financial and business matters to be capable of evaluating the merits and risks of its investment in the Exchange
Shares and is capable of bearing the economic risks of such investment.

 

(c)NNA and its advisers
have been furnished with all materials relating to the business, finances and operations of Company, its Subsidiaries and materials
relating to the offer and sale of the Exchange Shares which have been requested by NNA or its advisers. NNA and its advisers have
been afforded the opportunity to ask questions of Company’s management concerning Company and the Exchange Shares.

 

(d)NNA understands
that except as provided in this Agreement or the Registration Rights Agreement, the sale or re-sale of the Exchange Shares has
not been and is not being registered under the Securities Act or any applicable state securities Laws, and the Exchange Shares
may not be offered, sold or otherwise transferred unless (i) the Exchange Shares are offered, sold or transferred pursuant to an
effective registration statement under the Securities Act, or (ii) the Exchange Shares are offered, sold or transferred pursuant
to an exemption from registration under the Securities Act and any applicable state securities Laws.

 

(e)The principal offices
of NNA and the offices of NNA in which it made its decision to purchase the Exchange Shares are located in the State of Massachusetts.

 

5.2Restricted Securities.
NNA understands that the Exchange Shares have not been registered under the Securities Act, by reason of one or more exemptions
from the registration provisions of the Securities Act. NNA understands that the Exchange Shares are “restricted securities”
under applicable U.S. federal and state securities Laws and that, pursuant to these Laws, NNA must hold the Exchange Shares
until such time as they are registered with the SEC and qualified by state authorities, or an exemption from such registration
and qualification requirements is available. NNA acknowledges that if an exemption from registration or qualification is available,
it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for
the Exchange Shares, and on requirements relating to Company which are outside of NNA’s control.

 

5.3Legends.
NNA understands that the Exchange Shares and any securities issued in respect of or exchange therefor, may be notated with one
or all of the following legends:

 

(a)“THE SECURITIES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH
A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION
STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
THE SECURITIES ACT OF 1933.”

 

(b)Any legend set
forth in, or required by, the other Transaction Documents.

 

    5 

     

    

 

(c)Any legend required
by the securities laws of any state to the extent such laws are applicable to the Exchange Shares represented by the certificate,
instrument, or book entry so legended.

 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 

  
 4 

 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 4.350% Bonds, Series 119 (hereinafter called the “bonds of Series 119”) and the terms and provisions to be contained in the bonds of Series
119 or to be otherwise applicable thereto to be as set forth in this Supplemental Indenture; and 
 WHEREAS, the bonds of Series 119 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 an order or 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 119, 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 bonds of Series 119, 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 119. The bonds of Series 119 shall, as hereinbefore recited, be designated as the Company’s “First Mortgage 4.350% Bonds, Series 119,” and shall be issued in the
original aggregate principal amount of $450,000,000. Subject to the provisions of the Mortgage, additional bonds of Series 119 may be issued 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 119.
(a) The definitive bonds of Series 119 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 119 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 119 shall mature on November 15, 2045. 

(c) The bonds of Series 119 shall bear interest at the rate of 4.350% per annum until the principal thereof shall be paid. 

(d) Interest on the bonds of Series 119 shall be payable semi-annually on the fifteenth day of May and the fifteenth day of November in each
year, commencing May 15, 2016. May 1 and November 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 119 so payable on any interest payment date shall, subject to the exceptions provided in Section 3.01 of the Mortgage, as 

  
 5 

 
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 May 1 or November 1, as the case
may be, next preceding such interest payment date. 
 SECTION 3. Execution of Bonds of Series 119. The bonds of
Series 119 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 119 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 119; Transferability and
Exchangeability. Both the principal of and interest on the bonds of Series 119 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 119 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 119. The bonds of Series 119 shall be issued in the denomination of $2,000 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 119 to be conclusively evidenced by the execution thereof on behalf of the Company. Bonds of Series 119
shall be numbered R-1 and consecutively upwards. 
 SECTION 6. Temporary Bonds of Series 119. Until definitive
bonds of Series 119 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 119. 
 SECTION 7. Redemption of Bonds of Series 119. (a) The bonds of Series 119
shall be redeemable, at the option of the Company, as a whole or in part, at any time prior to May 15, 2045 (six months prior to the maturity date of the bonds of Series 119) upon notice sent by the Company 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 or her 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 119 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 119 to be redeemed that would be due if such bonds of Series 119 matured on May 15, 2045 but for the
redemption (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 basis points, plus accrued and unpaid interest up to but excluding the redemption date. 

  
 6 

 The bonds of Series 119 shall be redeemable, at the option of the Company, as a whole or in part, at any time on
or after May 15, 2045 upon notice sent by the Company 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 or her address appearing upon the registration books, at a redemption price equal to 100% of the principal amount of the bonds of Series 119 to be redeemed, plus accrued and unpaid interest on those bonds of Series
119 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 119 or portions of the bonds of Series 119 called for redemption. 
 (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 119 to be redeemed (assuming, for this purpose, that the bonds of Series 119 matured on May 15, 2045) 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 119. 

“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 Quotation Agent 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. 

  
 7 

 “Reference Treasury Dealer” means (1) each of
(a) Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated and (b) a Primary Treasury Dealer (as defined below) selected by Wells Fargo Securities, LLC, and in each case their respective successors
and affiliates, unless such entity ceases to be a primary U.S. Government securities dealer in the United States of America (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 Quotation Agent, 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 Quotation Agent by that Reference Treasury Dealer at 3:30 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 119 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 119 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 119 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 119 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 119 (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 119 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 119, 
 (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 119, of any notice with respect to the bonds of Series 119, 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 119, of any amount with respect to principal of, redemption premium, if any, on, or interest on, the bonds of Series 119, or 

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

  
 8 

 So long as certificates for the bonds of Series 119 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 119 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 119 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 119, 
 the bonds of Series 119 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 119 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 119 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 119 are held by DTC, such bonds of Series 119 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 

  
 9 

 
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 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 

  
 10 

 
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. 

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 119 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 November 4, 2015, 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 119). 

  
 11 

 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 Assistant 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.
