Section 2.06(g) hereof, the requirements of this Section 2.06(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of

(iii) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted
Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(ii) hereof and the Registrar receives

Agreement and the holder of the beneficial interest to be transferred, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable Letter of Transmittal that it is not (1) a broker-dealer, (2) a
Person participating in the distribution of the Exchange Notes or (3) a Person who is an affiliate (as defined in Rule 144) of the Issuer;

proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Global Note of the same series, a certificate from such Holder substantially in the form of Exhibit D hereto, including the certifications in
item (1)(a) thereof; or 
 (2) if the holder of such beneficial interest in a Restricted Global Note
proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note of the same series, a certificate from such holder in the form of Exhibit C
hereto, including the certifications in item (4) thereof; 
 and, in each such case set forth in this subparagraph (D), if the

transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act. 
 If any such transfer is effected pursuant to subsection (B) or (D) above at a time when an Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Issuer
Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred
pursuant to subparagraph (B) or (D) above. 
 Notwithstanding the provisions of the first sentence of this
subparagraph (iv), at the option of the Issuer, beneficial interests in a Restricted Global Note shall automatically be exchanged for beneficial interests in an Unrestricted Global Note upon the Issuer’s compliance in full with the
Depositary’s “Procedures for the Mandatory Exchange of Rule 144A Securities for Unrestricted Securities” or “Procedures for the Mandatory Exchange of Regulation S Securities for Unrestricted Securities,” as applicable (or
such replacement procedures as the Depositary shall put in place). Upon such exchange of beneficial interests pursuant to this Section 2.06(b)(iv), the Registrar shall reflect on its books and records the date of such exchange and a decrease
and increase in the principal amount of the applicable Restricted Global Note and the Unrestricted Global Note, respectively, equal to the principal amount of beneficial interests exchanged. Following any such exchange pursuant to this
Section 2.06(b)(iv) of all of the beneficial interests in a Restricted Global Note to an Unrestricted Global Note, such Restricted Global Note shall be cancelled. 
 Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

 (c) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global
Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such 

  
 8 

 
Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a
Global Note is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person
who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the
direction of the Trustee to reflect such increase.

Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof. 
 (g)

 [Back of Note] 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) INTEREST. Energy Future Intermediate Holding Company LLC, a Delaware limited liability company
(“EFIH”), and EFIH Finance Inc., a Delaware corporation (collectively, the “Issuer”), promise to pay interest on the principal amount of this Note at 10.000% per annum from August 17, 2010
until maturity. The Issuer will pay interest semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”)
without interest accruing on the amount then so payable from such day that is not a Business Day until such Business Day. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid,
from and including December 1, 2012. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the
Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the interest rate on the
Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2)
METHOD OF PAYMENT. The Issuer will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15
(whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are canceled after such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. Payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will
be required with respect to principal, premium, if any, and interest on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment shall be 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. 

(3) PAYING AGENT AND REGISTRAR. Initially, The Bank of
New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may act in any
such capacity. 
 (4) INDENTURE. The Issuer issued the Notes under an Indenture, dated as
of August 17, 2010, between the Issuer and the Trustee, as supplemented by the First Supplemental Indenture, dated as of January 29, 2013, between the Issuer and the Trustee (as so supplemented, the “Indenture”). This Note
is one of a duly authorized issue of notes of the Issuer designated as its 10.000% Senior Secured Notes due 2020 (the “Notes”). The Issuer shall be entitled to issue Additional Notes pursuant to Sections 2.01, 4.09 and 4.12 of the
Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Notes are subject to all such
terms, and Holders are referred to the Indenture and such Act for a statement of such 

  
 A-3

 
terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

Interest Payment Date. 
 (c) From and after December 1, 2015, the Issuer may redeem the Notes, in whole or in part, upon

relevant Record Date to receive interest due on the relevant Interest Payment Date, with the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the sum of the original aggregate principal amount of Initial Notes
and any Additional Notes issued under the Indenture after the Issue Date remains outstanding immediately after the occurrence of each such redemption; provided further that each such redemption occurs within 90 days of the date of
closing of each such Equity Offering. Notice of any redemption upon any Equity Offerings may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuer’s discretion, be subject to one or more conditions
precedent, including, but not limited to, completion of the related Equity Offering. 

  
 A-4

 (e) If the Issuer redeems less than all of the outstanding Notes, the Trustee shall select
the Notes to be redeemed in the manner described under Section 3.02 of the Indenture. 
 (f) Any redemption pursuant to
this paragraph 5 shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture. 
 (6)
MANDATORY REDEMPTION. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 

(7) NOTICE OF REDEMPTION. Subject to Section 3.03 of the
Indenture, notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date (except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is

may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for
redemption. 
 (8) OFFERS TO REPURCHASE. 

(a) If a Change of Control occurs, the Issuer shall make an offer (a “Change of Control Offer”) to each Holder to
purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to the
date of purchase (the “Change of Control Payment”), subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. The Change of Control Offer shall be
made in accordance with Section 4.14 of the Indenture. 
 (b) If EFIH or any of its Restricted Subsidiaries consummates an
Asset Sale (other than an Asset Sale of Collateral or other Oncor-related Assets), within 10 Business Days of each date that the aggregate amount of Excess Proceeds exceeds $200.0 million, EFIH shall make an offer to all Holders of the Notes, and if
required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is
a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to
the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes, and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the
Excess Proceeds, EFIH may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes or such Senior Indebtedness surrendered by such holders

any time after consummation of such Asset Sale (other than an Asset Sale of Collateral or other Oncor-related Assets); provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of
such Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed Excess Proceeds. 
 (d) If
EFIH or any of its Restricted Subsidiaries consummates an Asset Sale of Collateral or other Oncor-related Assets, within 10 Business Days of each date that the aggregate amount of Collateral Excess Proceeds exceeds $200.0 million, EFIH and/or any of
its Restricted Subsidiaries shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any Parity Lien Debt, to the holders of such Parity Lien Debt (and if required or permitted by the terms of any Indebtedness of
EFH Corp. that is guaranteed by EFIH and constitutes Parity Lien Debt, EFH Corp. may make an offer to all holders of such Indebtedness) (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of the
Notes and such Parity Lien Debt that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and such Parity Lien Debt tendered
pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, EFIH and/or any of its Restricted Subsidiaries may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other covenants
contained in the Indenture and the terms of such Parity Lien Debt. If the aggregate principal amount of Notes or the Parity Lien Debt surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, the Notes and such Parity
Lien Debt will be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Parity Lien Debt tendered. 
 (e) The Issuer (and, if applicable, EFH Corp.) may, at its option, make a Collateral Asset Sale Offer using proceeds from any Asset Sale of Collateral or other Oncor-related Assets at any time after
consummation of such Asset Sale; provided that such Collateral Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of such Collateral Asset Sale Offer, any Net Proceeds not required to be used to
purchase Notes shall not be deemed Collateral Excess Proceeds and the Issuer and its Restricted Subsidiaries may use any remaining Net Proceeds for general corporate purposes, subject to the other covenants contained in the Indenture.

form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any
Notes or portion of Notes selected for redemption, except for the unredeemed portion of any Notes being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to

(12) DEFAULTS AND REMEDIES. The Events of Default relating to the
Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the then outstanding Notes may declare the principal, premium, if
any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Guarantees except as provided in the Indenture. Subject to certain limitations, Holders of a majority
in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment
of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal, premium, if any, or interest on, any of the Notes held by a non-consenting Holder. EFIH is required to
deliver to the Trustee annually a statement regarding compliance with the Indenture, and EFIH is required within five Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and what action
the EFIH proposes to take with respect thereto. 
 (13) AUTHENTICATION. This Note shall not
be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee. 
 (14) GOVERNING LAW. THE INDENTURE, THE NOTES AND THE GUARANTEES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 

(15) CUSIP/ISIN NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Issuer has caused CUSIP/ISIN numbers to be printed on the Notes and the Trustee may use CUSIP/ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such
numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 The Issuer will furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Security Documents. Requests may be made to the Issuer at the following address:

 1. CAPITALIZED TERMS. Capitalized
terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 2. ADDITIONAL
NOTES. Pursuant to this Second Supplemental Indenture, the New Toggle Notes are hereby created and established under the Indenture, and shall constitute “Additional Notes” thereunder, and are being issued by the Issuer on
the date hereof in an aggregate principal amount of $63,930,000, which shall increase the aggregate principal amount of, and shall form part of the same series as, the Existing Toggle Notes. The New Toggle Notes issued hereunder shall rank pari

 3. MANDATORY EXCHANGE OF REGULATION S GLOBAL NOTES. New Toggle Notes issued in the form of Regulation S Global
Notes (collectively, the “Initial Regulation S Global Notes”) shall bear the Temporary Regulation S Note CUSIP set forth on Exhibit A hereto until the 40th day after the date hereof. Notwithstanding the provisions of Section 2.06 of the Indenture, on or after such
40th day, at the option of the Issuer, upon instruction of
the Issuer to the Trustee, beneficial interests in the Initial Regulation S Global Notes shall automatically be exchanged for beneficial interests in one or more Regulation S Global Notes bearing the Permanent Regulation S Note CUSIP set forth on

and a decrease and increase in the principal amount of the applicable Regulation S Global Notes, equal to the principal amount of beneficial interests exchanged. Following any such exchange pursuant to this Section 3, the Initial Regulation S
Global Notes shall be cancelled. 
 4. MANDATORY REDEMPTION. The provisions of Section 3.08
and paragraph 6 of the Notes shall apply to the New Toggle Notes.

 [Back of Note] 
 This Note is one of a duly authorized series of notes of the Issuer designated as the “11.25%/12.25% Senior Toggle Notes due 2018” (the “Notes”), previously issued in an aggregate
principal amount of $1,144,770,000 on December 5, 2012 and in an aggregate principal amount $159,032,000 on December 19, 2012, for a total aggregate principal amount of $1,303,802,000, and as a result of a further issuance of $63,930,000
aggregate principal amount of Notes on January 29, 2013, now issued in an aggregate principal amount of $1,367,732,000 under the Indenture referred to below. 
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

(1) INTEREST. Energy Future Intermediate Holding Company LLC, a Delaware limited liability company
(“EFIH”), and EFIH Finance Inc., a Delaware corporation (collectively, the “Issuer”), promise to pay interest on the principal amount of this Note at a rate per annum set forth below from December 5,
2012 until maturity and shall pay Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuer will pay interest (including Additional Interest, if any) semi-annually in arrears on June 1 and
December 1 of each year, commencing on June 1, 2013, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”) without interest accruing on the amount then so payable
from such day that is not a Business Day until such Business Day. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including December 5, 2012. The Issuer will
pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the Notes; it shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (including Additional Interest, if any)(without regard to any applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest
will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 Cash Interest on the Notes will accrue at
a rate of 11.25% per annum and be payable in cash. PIK Interest on the Notes will accrue at a rate of 12.25% per annum and be payable (x) with respect to Notes represented by one or more global notes registered in the
name of, or held by, The Depository Trust Company (“DTC”) or its nominee on the relevant Record Date, by increasing the principal amount of the outstanding global Note by an amount equal to the amount of PIK Interest for the
applicable interest period (rounded up to the nearest $1,000) (or, if necessary, pursuant to the requirements of DTC or otherwise, to authenticate new global Notes executed by the Issuer with such increased principal amounts) and (y) with
respect to Notes represented by certificated notes, by issuing PIK Notes in certificated form in an aggregate principal amount equal to the amount of PIK Interest for the applicable period (rounded up to the nearest whole dollar), and the Trustee
will, at the request of the Issuer, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant Record Date, as shown by the records of the register of Holders. In the event that the Issuer
elects to pay Partial PIK Interest for any interest period, each Holder will be entitled to receive Cash Interest in respect of 50% of the principal amount of the Notes held by such Holder on the relevant

  
 A-3

 
Record Date and PIK Interest in respect of 50% of the principal amount of the Notes held by such Holder on the relevant Record Date. Following an increase in the principal amount of the
outstanding global Notes as a result of a PIK Payment, the global Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in certificated form will be dated as of the applicable
Interest Payment Date and will bear interest from and after such date. All Notes issued pursuant to a PIK Payment will mature on December 1, 2018 and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and
shall have the same rights and benefits as the Notes issued on the Issue Date. Any certificated PIK Notes will be issued with the description PIK on the face of such PIK Note. 
 (2) METHOD OF PAYMENT. For any interest payment period ending prior to June 1, 2016, the Issuer may, at its option elect to pay
interest on the Notes: 
 (i) entirely in cash (“Cash Interest”); 

(ii) entirely by increasing the principal amount of the outstanding Notes or by issuing PIK Notes (“PIK Interest”); or

 (iii) on 50% of the outstanding principal amount of the Notes in cash and on 50% of the outstanding principal amount by
increasing the principal amount of the outstanding Notes or by issuing PIK Notes (“Partial PIK Interest”). 

The Issuer must elect the form of interest payment with respect to each interest period by delivering a notice to the Trustee prior to
the beginning of such interest period; provided that the interest payment with respect to the first interest period shall be payable entirely in PIK Interest, and the Issuer shall not be required to deliver a notice to the Trustee with
respect to the election for such first interest period. The Trustee shall promptly deliver a corresponding notice to the Holder of this Note. In the absence of such an election for any interest period, interest on this Note shall be payable
according to the election for the previous interest period. Beginning with the June 1, 2016 Interest Payment Date, the Issuer will make all interest payments on this Note entirely in cash. Notwithstanding anything to the contrary, the payment
of accrued interest in connection with any redemption of Notes as described under Sections 3.07, 4.10 and 4.14 of the Indenture shall be made solely in cash. 
 The Issuer will pay Cash Interest on the Notes (including Additional Interest, if any) to the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15
(whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are canceled after such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. Payment of Cash Interest (including Additional Interest, if any) may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire
transfer of immediately available funds will be required with respect to principal of, and premium, if any, and interest (including Additional Interest, if any) on, all Global Notes and all other Notes the Holders of which shall have provided wire
transfer instructions to the Issuer or the Paying Agent. Such payment shall be 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. 

  
 A-4

 (3) PAYING AGENT AND
REGISTRAR. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to
the Holders. The Issuer or any of its Subsidiaries may act in any such capacity. 
 (4)
INDENTURE. The Issuer issued the Notes under an Indenture, dated as of December 5, 2012, as supplemented by a First Supplemental Indenture, dated as of December 19, 2012, and a Second Supplemental
Indenture, dated as of January 29, 2013, each between the Issuer and the Trustee (as so supplemented, the “Indenture”). This Note is one of a duly authorized issue of notes of the Issuer designated as its 11.25%/12.25% Senior
Toggle Notes due 2018 (the “Notes”). The Issuer shall be entitled to issue Additional Notes pursuant to Sections 2.01, 4.09 and 4.12 of the Indenture. The terms of the Notes include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939, as amended. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

(5) OPTIONAL REDEMPTION. 
 (a) Except as set forth below, the Issuer will not be entitled to redeem Notes at its option prior to December 1, 2014. 
 (b) At any time prior to December 1, 2014, the Issuer may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to the
registered address of each Holder of Notes or otherwise delivered in accordance with procedures of DTC, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium, plus accrued and
unpaid interest (including Additional Interest, if any) to the applicable date of redemption (the “Redemption Date”), subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the
relevant Interest Payment Date. 
 (c) From and after December 1, 2014, the Issuer may redeem the Notes, in whole or in
part, upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to the registered address of each Holder of Notes, or otherwise delivered in accordance with the procedures of DTC, at the redemption prices
(expressed as percentages of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest (including Additional Interest, if any) to the applicable Redemption Date, subject to the right of Holders of Notes of
record on the relevant Record Date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on December 1 of each of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2014
	  	 	105.6250	% 
	 2015
	  	 	105.6250	% 
	 2016 and thereafter
	  	 	102.8125	% 

 (d) Prior to December 1, 2014, the Issuer may, at its option, on one or more occasions, redeem up to
35% of the aggregate principal amount of all Notes at a redemption 

  
 A-5

 
price equal to 111.25% of the aggregate principal amount thereof, plus accrued and unpaid interest (including Additional Interest, if any) to the Redemption Date, subject to the right of Holders
of Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date, with the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the sum of the original aggregate
principal amount of Initial Notes and any Additional Notes issued under the Indenture after the Issue Date remains outstanding immediately after the occurrence of each such redemption; provided further that each such redemption occurs
within 90 days of the date of closing of each such Equity Offering. Notice of any redemption upon any Equity Offerings may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuer’s discretion, be
subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering. 
 (e) If
the Issuer redeems less than all of the outstanding Notes, the Trustee shall select the Notes to be redeemed in the manner described under Section 3.02 of the Indenture. 
 (f) Any redemption pursuant to this paragraph 5 shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture. 

(6) MANDATORY REDEMPTION. Except as set forth below, the Issuer shall not be required
to make mandatory redemption or sinking fund payments with respect to the Notes. 
 If the Notes would otherwise constitute
“applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code, at the end of each “accrual period” (as defined in Section 1272(a)(5) of the Code) ending after the fifth anniversary of
the Issue Date (each, an “AHYDO Redemption Date”), the Issuer will be required to redeem for cash a portion of the then outstanding Notes equal to the “Mandatory Principal Redemption Amount” (each such redemption, a
“Mandatory Principal Redemption”). The redemption price for the portion of the Notes redeemed pursuant to any Mandatory Principal Redemption will be 100% of the aggregate principal amount of such portion of the Notes to be redeemed
plus any accrued interest thereon (including Additional Interest, if any) on the date of the redemption. “Mandatory Principal Redemption Amount” means, as of each AHYDO Redemption Date, the portion of the Notes required to be
redeemed at such date to prevent the Notes from being treated as “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code. No partial redemption or repurchase of the Notes prior to any AHYDO
Redemption Date pursuant to any other provision of the Indenture will alter the Issuer’s obligation to make any Mandatory Principal Redemption with respect to the Notes that remain outstanding on such AHYDO Redemption Date. 

(7) NOTICE OF REDEMPTION. Subject to Section 3.03 of the
Indenture, notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date (except that redemption notices may be mailed or delivered more than 60 days prior to a
Redemption Date if the notice is issued in connection with Article 8 or Article 11 of the Indenture) to each Holder whose Notes are to be redeemed at its registered address or otherwise delivered in accordance with the procedures of DTC.
Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on
Notes or portions thereof called for redemption. 

  
 A-6

 (8) OFFERS TO REPURCHASE. 

(a) If a Change of Control or EFIH/EFH Merger occurs, the Issuer shall make an offer (in the case of a Change of Control, a
“Change of Control Offer”; and, in the case of an EFIH/EFH Merger, an “EFIH/EFH Merger Offer”) to each Holder to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each
Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest (including Additional Interest, if any) to the date of purchase (in the case of a Change of Control, the “Change
of Control Payment”; and, in the case of an EFIH/EFH Merger, the “EFIH/EFH Merger Payment”), subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the relevant Interest
Payment Date. The Change of Control Offer or EFIH/EFH Merger Offer, as applicable, shall be made in accordance with Section 4.14 of the Indenture. 
 (b) If EFIH or any of its Restricted Subsidiaries consummates an Asset Sale (other an Asset Sale of Collateral or Other Oncor Assets), within 10 Business Days of each date that the aggregate amount of
Excess Proceeds exceeds $200.0 million, EFIH shall make an offer to all Holders of the Notes, and if required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale
Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an
offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the procedures set
forth in the Indenture. To the extent that the aggregate amount of Notes, and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, EFIH may use any remaining Excess Proceeds for general corporate
purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes or such Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Notes and such Senior Indebtedness
will be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered. 
 (c) EFIH may, at its option, make an Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale (other than an Asset Sale of Collateral or other Oncor-related
Assets); provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of such Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed
Excess Proceeds. 
 (d) If EFIH or any of its Restricted Subsidiaries consummates an Asset Sale of Collateral or other
Oncor-related Assets and a Collateral Asset Sales Offer, or sequential Collateral Asset Sales Offers to holders of Senior Lien Debt and Junior Lien Debt, EFIH or any Restricted Subsidiary shall make an offer to all Holders of the Notes and, if
required or permitted by the terms of any of any other unsecured Senior Indebtedness of EFIH, to the holders of such other unsecured Senior Indebtedness (a “Collateral Asset Sale Excess Proceeds Offer”) to purchase the maximum
aggregate principal amount of such unsecured Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Collateral Offer Excess Proceeds at an offer price in cash in an amount
equal to 100% 

  
 A-7

 
of the principal amount thereof, plus accrued and unpaid interest (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the terms and
procedures set forth in this Indenture and the other applicable indentures or agreements. 
 (e) The Issuer (and, if applicable,
EFH Corp.) may, at its option, make a Collateral Asset Sale Excess Proceeds Offer using proceeds from any Asset Sale of Collateral or other Oncor-related Assets at any time after consummation of such Asset Sale of Collateral; provided that
such Collateral Asset Sale Excess Proceeds Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of such Collateral Asset Sale Excess Proceeds Offer, any Net Proceeds not required to be used to purchase the
Notes and such unsecured Senior Indebtedness shall not be deemed Collateral Offer Excess Proceeds and EFIH and its Restricted Subsidiaries may use any remaining Net Proceeds for general corporate purposes, subject to the other covenants contained in
this Indenture. 
 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The
Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or
register the transfer of any Notes or portion of Notes selected for redemption, except for the unredeemed portion of any Notes being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of
15 days before a selection of Notes to be redeemed. 
 (10) PERSONS DEEMED
OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 
 (11)
AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Guarantees or the Notes may be amended or supplemented as provided in the Indenture. 

(12) DEFAULTS AND REMEDIES. The Events of Default relating to the
Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Required Holders of at least 30% in aggregate principal amount of the then outstanding Required Debt may declare the
principal of and premium, if any, interest (including Additional Interest, if any) and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all principal of, and premium, if any, interest (including Additional Interest, if any) and any other monetary obligations on, all the then outstanding Notes will become due and
payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Guarantees except as provided in the Indenture. Subject to certain limitations, Required Holders of a majority in aggregate principal
amount of the then outstanding Required Debt may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal,
premium, if any, or interest (including Additional Interest, if any)) if it determines that withholding notice is in their interest. The Required Holders of a majority in aggregate principal amount of the then outstanding Required Debt by notice to
the Trustee may on behalf of the Required Holders of all of the Required Debt waive any existing Default or and its consequences under the Indenture except a continuing 

  
 A-8

 
Default in payment of the principal of, or premium, if any, or interest (including Additional Interest, if any) on, any of the Notes held by a non-consenting Holder. EFIH is required to deliver
to the Trustee annually a statement regarding compliance with the Indenture, and EFIH is required within five Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and what action EFIH
proposes to take with respect thereto. 
 (13) AUTHENTICATION. This Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee. 
 (14) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders of Notes under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes shall have
all the rights set forth in the Registration Rights Agreement, dated as of January 29, 2013, among the Issuer and the other parties named on the signature pages thereof (the “Registration Rights Agreement”), including the right
to receive Additional Interest, if any (as defined in the Registration Rights Agreement). 
 (15) GOVERNING
LAW. THE INDENTURE, THE NOTES AND THE GUARANTEES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 (16) CUSIP/ISIN NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP/ISIN
numbers to be printed on the Notes and the Trustee may use CUSIP/ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 The Issuer will
furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Registration Rights Agreement. Requests may be made to the Issuer at the following address:
