 Payment of the principal of (and premium, if any) and interest at Maturity on this Security shall

thereof to all of the terms and provisions of the Indenture. This Security is one of the series designated on the face hereof. 
 This
Security is subject to redemption at the election of the Company, in whole at any time or in part from time to time, at a redemption price as calculated by the Company equal to the greater of 

 

	 	•	 	100% of the principal amount of the Securities of this series being redeemed, or 

  

	 	•	 	the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series being redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day

 plus, in each case, accrued interest on
those Securities of this series to the redemption date. 
 “Treasury Rate” means, with respect to any redemption date, the rate

Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, 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 Securities. 

  
 A-3 

 “Comparable Treasury Price” means, with respect to any redemption date, (i) the
average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the H. 15 Daily Update of the Federal

foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer.

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 the Reference Treasury Dealer at 5:00 p.m. on the third
business day preceding such redemption date. 
 The Company shall deliver to the Trustee before any Redemption Date for the Securities of
this series its calculation of the Redemption Price applicable to such redemption. Except with respect to the obligations of the Trustee expressly set forth in the foregoing definitions of “Comparable Treasury Issue” and “Comparable
Treasury Price,” the Trustee shall be under no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon the Company’s calculation of any Redemption Price of the Securities of this series. 

In lieu of stating the Redemption Price, notices of redemption of the Securities of this series shall state substantially the following:
“The Redemption Price of the Securities of this series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such Securities of this series, or (ii) the sum of the present values of the
remaining scheduled payments of principal and interest on the Senior Notes being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis
points, plus accrued interest on the principal amount hereof to the Redemption Date.” 
 Notice of redemption (other than at the option
of the Holder) shall be given by mail to Holders of Securities, not less than 30 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as

 A-4 

 
and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money
is not so received and, in such event, the Company shall not be required to redeem this Security. 
 In the event of redemption of this
Security in part only, a new Security or Securities of this series of like tenor representing the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

conditions set forth therein. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the
principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the

Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the
right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of
Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing
shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate
principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding,
for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on
or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

cover any tax or other governmental charge payable in connection therewith.

of this series for a period of 15 days next preceding an Interest Payment Date. 
 The Company, the Trustee and any agent of the Company or
the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to
the contrary.

 ONCOR ELECTRIC DELIVERY COMPANY 

7.250% SENIOR SECURED NOTES DUE 2033 

ONCOR ELECTRIC DELIVERY COMPANY, a corporation duly organized and existing under the laws of the State of Texas (herein referred to as the
“Company”, which term includes any successor Person under the Indenture referred to below), for value received, hereby promises to pay to 
 or
registered assigns, the principal sum of                     ($            ) Dollars
on January 15, 2033, and to pay interest on said principal sum semi-annually in arrears on January 15 and July 15 of each year commencing July 15, 2003 (each an “Interest Payment Date”) at the rate of 7.250% per annum
until the principal hereof is paid or made available for payment. Interest on the Securities of this series will accrue from and including December 20, 2002, to and excluding the first Interest Payment Date, and thereafter will accrue from and
including the last Interest Payment Date to which interest has been paid or duly provided for. No interest will accrue on the Securities with respect to the day on which the Securities mature. In the event that any Interest Payment Date is not a
Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on the
Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on December 31 for the January 15 Interest Payment Date and on July 1 for the July 15 Interest Payment Date (each a “Regular Record Date”) immediately preceding such Interest Payment
Date, except that interest payable at Maturity will be payable to the Person to whom principal shall be paid. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the

  
 B-2 

 
Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture referred to herein. 

Payment of the principal of (and premium, if any) and interest at Maturity on this Security shall be made upon presentation of this Security
at the office or agency of the Company maintained for that purpose in The City of New York, in the State of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts, provided, however, that, at the option of the Company, interest on this Security (other than interest payable at Maturity) may be paid by check mailed to the address of the person entitled thereto, as such address shall appear on the
Security Register, and provided, further, that if such person is a securities depositary, such payment may be made by such other means in lieu of check as shall be agreed upon by the Company, the Trustee and such person. 

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture and in the
Officer’s Certificate establishing the terms of the Securities of this series.

called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York, as Trustee (herein called the “Trustee”, which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture, for a statement of the property mortgaged, pledged and held in trust, the nature and extent of the security, the conditions upon which the Lien of the Indenture may be released and to

and provisions of the Indenture. This Security is one of the series designated on the face hereof. 
 This Security is subject to redemption
at the election of the Company, in whole at any time or in part from time to time, at a redemption price equal to the greater of 
  

	 	•	 	100% of the principal amount of the Securities of this series being redeemed, or 

  

	 	•	 	the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series being redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points, 

 plus, in each case, accrued interest on
those Securities of this series to the redemption date. 
 “Treasury Rate” means, with respect to any redemption date, the rate
per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such

 B-3 

 “Comparable Treasury Issue” means the United States Treasury security selected by the
Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, 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 Notes. 
 “Comparable Treasury Price” means, with respect to
any redemption date, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the H.

redemption date.

or any successor publication, published by the Board of Governors of the Federal Reserve System.

daily update of H.15(519) available through the worldwide website of the Board of Governors of the Federal Reserve System or any successor site or publication. 

“Independent Investment Banker” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means Merrill Lynch Government Securities, Inc., and its successors; provided, however, that if the
foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotation” means, with respect to the 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 the Reference Treasury Dealer at 5:00 p.m. on the 

third business day preceding such redemption date. 

The Company shall deliver to the Trustee before any Redemption Date for the Securities of this series its calculation of the Redemption Price
applicable to such redemption. Except with respect to the obligations of the Trustee expressly set forth in the foregoing definitions of “Comparable Treasury Issue” and “Comparable Treasury Price,” the Trustee shall be under no
duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon the Company’s calculation of any Redemption Price of the Securities of this series. 

In lieu of stating the Redemption Price, notices of redemption of the Securities of this series shall state substantially the following:
“The Redemption Price of the Securities of this series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such Securities of this series, or (ii) the sum of the present values of the
remaining scheduled payments of principal and interest on the Securities of this series being redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus
35 basis points, plus accrued interest on the principal amount hereof to the Redemption Date.” 

  
 B-4 

 Notice of redemption (other than at the option of the Holder) shall be given by mail to Holders
of Securities, not less than 30 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be
conditional upon the receipt by the applicable Paying Agent or Agents of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption
so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security. 

In the event of redemption of this Security in part only, a new Security or Securities of this series of like tenor representing the
unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Indenture contains
provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture. 

The Indenture contains provisions for release of the Lien thereof upon compliance with certain conditions set forth therein. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal
amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 As provided in and
subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless
such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time
Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable
indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a
direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this
Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

  
 B-5 

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

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein and herein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of
authorized denominations, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

The Company shall not be required to execute and the Security Registrar shall not be required to register the transfer of or exchange of
(a) Securities of this series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities of this series called for redemption or (b) any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed in part. The Company shall not be required to make transfers or exchanges of the Securities of this series for a period of 15 days next preceding an Interest Payment
Date. 
 The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered
as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

Each Holder shall be deemed to understand that the offer and sale of the Securities of this series have not been registered under the
Securities Act and that the Securities of this series may not be offered or sold except as permitted in the following sentence. Each Holder shall be deemed to agree, on its own behalf and on behalf of any accounts for which it is acting as
hereinafter stated, that if such Holder sells any Securities of this series, such Holder will do so only (A) to the Company, (B) to a person whom it reasonably believes is a “qualified institutional buyer” within the meaning of
Rule 144A under the Securities Act that purchases for its own account or for the account of a qualified institutional buyer to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A, (C) to an
institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act) that, prior to such transfer, furnishes to the Trustee a signed letter containing certain representations and agreements
relating to the restrictions on transfer of the Securities of this series, (D) in an offshore transaction in accordance with Rule 904 of Regulation S under the Securities Act, (E) pursuant to the exemption from registration provided by Rule 144
under the Securities Act (if available), or (F) pursuant to an effective registration statement under the Securities Act, and each Holder is further deemed to agree to provide to any person purchasing any of the Securities of this series from
it a notice advising such purchaser that resales of the Securities of this series are restricted as stated herein. 
 Each Holder shall be
deemed to understand that, on any proposed resale of any Securities of this series pursuant to the exemption from registration under Rule 144 under the Securities Act, any Holder making any such proposed resale will be required to furnish to the
Trustee and Company such certifications, legal opinions and other information as the Trustee and Company may reasonably require to confirm that the proposed sale complies with the foregoing restrictions. 

  
 B-6 

 This Security shall be governed by and construed in accordance with the laws of the State of New
York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable and except to the extent that the laws of the
State of Texas shall mandatorily govern. 
 As provided in the Indenture, no recourse shall be had for the payment of the principal of or
premium, if any, or interest on any Securities, or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under the Indenture,
against, and no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, member, officer or director, as such, past, present or future of the Company or of any predecessor or successor corporation (either
directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and
understood that the Indenture and all the Securities are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the
Indenture and the issuance of the Securities.

considered as one class, except as expressly contemplated in subsections (b) and (c) of this Section. 
 (b) The provisions of

 (i) the Company shall make
effective provision whereby the Benefitted Securities shall be secured at least equally and ratably with such Secured Debt; or 

(ii) the Company shall deliver to the Trustee bonds, notes or other evidences of indebtedness secured by the Lien which secures
such Secured Debt (hereinafter called “Secured Obligations”) (i) in an aggregate principal amount equal to the aggregate principal amount of each series then Outstanding, (ii) maturing (or being subject to mandatory redemption)
on the Stated Maturities of such series and (iii) containing, in addition to any mandatory redemption provisions applicable to all Secured Obligations outstanding under such Lien and any mandatory redemption provisions contained therein pursuant to

the aggregate principal amount of indebtedness issuable, and then proposed to be issued, under and secured by such Lien; 

(iii) an Opinion of Counsel (i) if the Outstanding Securities under this Indenture are to be secured by such Lien, to the
effect that all Securities then Outstanding are entitled to the benefit of such Lien equally and ratably with all other indebtedness outstanding secured by such Lien or (ii) if Secured Obligations are to be delivered to the Trustee, to the
