This is one of the Notes referred to in the within-mentioned Indenture:

THE BANK OF NEW YORK MELLON

TRUST COMPANY, N.A., as Trustee

By:

Authorized Signatory

Dated:

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, in an aggregate principal amount of $159,032,000 on December 19, 2012 and in an aggregate principal amount of $63,930,000 on January 29, 2013, for a total aggregate principal amount of $1,367,732,000, and as a result of a further issuance of $24,713,000 aggregate principal amount of Notes on January 30, 2013, now issued in an aggregate principal amount of $1,392,445,000 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 A-4 in respect of 50% of the principal amount of the Notes held by such Holder on the relevant 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.

(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, a Second Supplemental Indenture, dated as of January 29, 2013, and a Third Supplemental Indenture, dated as of January 30, 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:

(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 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 A-10 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 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 A-10 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% 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 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 December 5, 2012, 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.
