LEASE AGREEMENT

(ERCOT TRANSMISSION ASSETS)

This LEASE AGREEMENT (ERCOT TRANSMISSION ASSETS) (this “Agreement”) is entered into on December 1, 2014 (the “Effective Date”), between Sharyland Distribution & Transmission Services, L.L.C. (together with its transferees, successors and assigns, “Lessor”), and Sharyland Utilities, L.P. (together with its transferees, successors and assigns, “Lessee”), and in connection herewith, Lessor and Lessee agree, covenant and contract as set forth in this Agreement. Lessor and Lessee are sometimes referred to in this Agreement as a “Party” or collectively as the “Parties”.

Certain capitalized terms used in this Agreement have the meaning assigned to them in Appendix A attached hereto.

WITNESSETH:

WHEREAS, Lessor owns certain transmission assets in Texas referred to as the ▇▇ ▇▇▇▇▇ substation and may acquire or build additional transmission assets in Texas that are subject to the jurisdiction of ERCOT; and

WHEREAS, Lessor and Lessee wish to enter into a lease agreement covering the ▇▇ ▇▇▇▇▇ substation and, in the future, to enter into lease agreements covering Footprint Projects that add, expand or alter transmission assets identified from time to time pursuant to Rent Supplements;

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Parties hereto hereby enter into this Agreement as follows:

ARTICLE I

LEASE

1.1. Lease of ERCOT Transmission Assets.

(a) Upon the terms and conditions set forth in this Agreement, Lessor hereby grants to Lessee the exclusive right to use and operate the ERCOT Transmission Lease Assets. Subject to necessary regulatory approvals and the penultimate sentence of this Section 1.1, this Agreement is intended by Lessor and Lessee to be a master lease of the ERCOT Transmission Lease Assets, as they exist as of the Effective Date, and as they may be altered or expanded thereafter by Footprint Projects in which Lessor has an interest or by other additions of assets to this Agreement as Footprint Projects pursuant to Rent Supplements.

(b) The ERCOT Transmission Assets shall consist of (x) the original assets leased by Lessor to Lessee as of the Effective Date, (y) assets that constitute Footprint Projects, other than any such Footprint Projects funded by Lessee pursuant to Section 10.3, and (z) any components of the ERCOT Transmission Assets that are repaired or replaced pursuant to Section 6.1. The ERCOT Transmission Assets shall consist of each of the following components which are owned by Lessor as of the Effective Date (or that are described within clause (y) or clause (z) above) and that are part of the ▇▇ ▇▇▇▇▇ Substation or that are added to this Agreement as Footprint Projects pursuant to Rent Supplements:

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(i) towers and poles affixed to the land, and all necessary and proper foundations, footings, crossarms and other appliances and fixtures for use in connection with said towers, poles and lines;

(ii) overhead, underground and underwater electrical distribution, transmission and communications lines, together with related ductwork and insulators;

(iii) electric substation and switching facilities, including all associated transformers, circuit breakers, resistors, capacitors, buses, interconnection and switching facilities, control and protection equipment which monitors the ERCOT Transmission Assets, and the building housing the foregoing items;

(iv) electric meters required to operate the ERCOT Transmission Assets;

(v) all facilities associated with HVDC Ties, including AC/DC converter stations;

(vi) real estate assets, including real property, interests in real property or real property rights (as defined in Section 856(c)(5)(B) of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, and not otherwise included in Sections 1.1(b)(i) – 1.1(b)(v) above) owned or leased by Lessor; or

(vii) all other systems or property owned or leased by Lessor, as identified in the uniform system of accounts for major electric utilities, 18 C.F.R. Part 101, as adopted and amended from time to time by FERC (not otherwise included in Sections 1.1(b)(i) – 1.1(b)(vi) above).

The ERCOT Transmission Assets exclude, for the avoidance of doubt, (a) the Transmission Operation Center and the transmission and distribution related assets included in the Backup Operations Center located in Amarillo, Texas, which are currently owned by Lessor and leased to Lessee pursuant to the McAllen Lease, (b) the transmission assets currently located in the ▇▇▇▇▇▇▇/▇▇▇▇▇/▇▇▇▇▇▇▇ service territory, owned by Lessor and leased to Lessee pursuant to the ▇▇▇▇▇▇▇/▇▇▇▇▇/▇▇▇▇▇▇▇ Lease, (c) the transmission assets currently located in Mission, Texas (Railroad Tie) owned by Lessor and leased to Lessee pursuant to the McAllen Lease, (d) the 138kv loop transmission assets located near Stanton, Texas owned by Lessor and leased to Lessee under the Stanton Transmission Loop Lease, and (e) certain transmission assets located in the Texas Panhandle and owned by Sharyland Projects, L.L.C., a subsidiary of Lessor, and leased to Lessee under the CREZ Lease. Notwithstanding anything to the contrary in this Agreement, the parties do not intend or agree to enter into a lease with respect to any Footprint Project or other alteration, expansion or addition to the ERCOT Transmission Assets (and the Lessee shall not be authorized to use or operate such Footprint Project, alteration, expansion or addition to the ERCOT Transmission Assets) unless and until such time as the parties first execute a Rent Supplement for the underlying Footprint Project and such Footprint Project is placed in service, and such Rent Supplement together with this Agreement shall be treated as a

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

new lease with respect to such Footprint Project. The parties further agree and acknowledge that a Rent Supplement will be executed with respect to each Footprint Project before such Footprint Project is placed in service, and references in this Agreement to “ERCOT Transmission Assets” rely on the assumption that this is the case.

1.2. Exclusive Rights. Throughout the Term of this Agreement, Lessee shall have the exclusive right (i) to operate and use the ERCOT Transmission Lease Assets for the transmission of electricity in accordance with applicable rules and regulations of all regulatory agencies having regulatory jurisdiction over the ERCOT Transmission Assets, including without limitation, PUCT, TRE, NERC and other Regulatory Authorities, and (ii) to utilize the ERCOT Transmission Lease Assets (and the associated easements, rights of way and similar rights) for other opportunities and uses (provided that such other uses do not interfere with the current or future transmission and delivery of electricity), subject to the approval of the Lessor, such approval not to be unreasonably withheld, conditioned or delayed. Throughout the Term of this Agreement, Lessor shall have access to the ERCOT Transmission Assets at all reasonable times for purposes of inspection and for the purposes of improving, expanding or modernizing the ERCOT Transmission Assets in accordance with Article X. Except in the case of emergency, prior to Lessor’s access of the ERCOT Transmission Assets, Lessor will provide written notification to Lessee’s operations personnel.

1.3. Absolute Net Lease. This Agreement is intended by the Parties to be an absolute net lease (and, except as otherwise specified herein, the expenses associated with the lease, servicing, insuring, maintenance, repair and operation of the ERCOT Transmission Assets shall be for the account of the Lessee, unless expressly stated that such expenses are for the account of Lessor or some other person or entity). Other than as expressly provided herein, (a) Lessee’s obligation to make all payments of Rent as and when the same shall become due and payable in accordance with the terms of this Agreement shall be absolute, irrevocable and unconditional and shall not be affected by any circumstance or subject to any abatement or diminution by set-off, deduction, counterclaim, recoupment, agreement, defense, suspension, deferment, interruption or otherwise, and (b) until such time as all Rent required to be paid has been paid, Lessee shall have no right to terminate this Agreement or to be released, relieved or discharged from its obligation to make, and shall not suspend or discontinue, any payment of Rent for any reason whatsoever.

1.4. Waiver by Lessee. Lessee hereby waives, to the extent permitted by Applicable Law, any and all rights which it may now have or which at any time hereafter may be conferred upon it, by statute or otherwise, to modify, terminate, cancel, quit or surrender this Agreement except in accordance with the express terms hereof.

1.5. Quiet Enjoyment. Lessee shall be entitled to the peaceful and quiet enjoyment of the ERCOT Transmission Assets, subject to the terms of this Agreement, so long as Lessee is not in default of this Agreement beyond applicable notice and cure periods.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

ARTICLE II

TERM OF LEASE

2.1. Term. Subject to the provisions of Section 2.2 of this Agreement, or as otherwise stated herein, this Agreement is effective on the Effective Date and shall continue through December 31, 2022 unless otherwise terminated in a manner consistent herewith (the “Initial Term”). Thereafter, this Agreement may be renewed for subsequent terms (each, a “Renewal Term” and, collectively with the Initial Term, the “Term”) by mutual agreement of the Parties; provided, however, that the Rent for any Renewal Term shall be targeted to provide the Lessor with a Comparable Rate of Return on the then-current Rate Base of the ERCOT Transmission Assets.

2.2. Approvals upon Expiration or Termination.

(a) Notwithstanding any provisions to the contrary herein, Lessee shall not surrender, resign, transfer, assign or otherwise cease to be the operator of the ERCOT Transmission Assets at any time, including upon the termination of this Agreement or at the expiration of the Term, without first acquiring any necessary regulatory approvals from the PUCT or other Regulatory Authorities regarding such surrender, resignation, transfer, assignment or cessation of such operatorship; provided that, in the event of expiration or termination, the Parties shall use commercially reasonable efforts to obtain all necessary regulatory approvals of the transfer of such operatorship as soon as reasonably practicable.

(b) During such extended period of operatorship, Lessee shall continue to operate the ERCOT Transmission Assets and shall continue to pay all Extended Period Rent; provided, however, that if regulatory approval is not obtained within twelve (12) months of initiation of the approval process and such delay is (a) due to Lessor’s failure to reasonably pursue such approval, then the amounts payable as Rent will be eighty percent (80%) of such amount, or (b) due to Lessee’s failure to reasonably pursue such approval, then the amounts payable as Rent will be one hundred five percent (105%) of such amount.

(c) Upon the expiration of the Term or termination of this Agreement, Lessee shall use commercially reasonable efforts to obtain all necessary regulatory approvals as soon as reasonably practicable from the PUCT or other Regulatory Authorities to transfer or assign the CCNs for the ERCOT Transmission Assets to Lessor or a third party designated by Lessor and acceptable to the PUCT or other Regulatory Authorities.

2.3. Purchase Option upon Expiration or Termination. Upon the expiration of the Term or termination of this Agreement, Lessor shall have the option to purchase from Lessee any equipment or other property, tangible or intangible, owned by Lessee and principally used in connection with and necessary for the operation of the ERCOT Transmission Assets (including any Nonseverable Footprint Projects owned by Lessee, if any), subject to any required regulatory approvals. The purchase price for such property or equipment shall be the greater of (i) the net book value thereof plus 10% and (ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail to agree on the amount of the purchase price, the purchase price shall be determined by arbitration pursuant to Section 13.7. In the event Lessor purchases such equipment, Lessee shall have the right to continue to use such equipment for no cost during the period of any extended operations by Lessee under Section 2.2.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

ARTICLE III

RENT

3.1. Rent. Lessee will pay to Lessor in lawful money of the United States of America which shall be legal tender for the payment of public and private debts, at Lessor’s address set forth in Section 13.8 hereof or at such other place or to such other Person, as Lessor from time to time may designate in a Notice, all Rent contemplated hereby during the Term on the basis hereinafter set forth. If there is a dispute as to the amount of Rent to be paid by Lessee, either Party may submit the dispute to arbitration pursuant to Section 13.7. However, Lessee shall be required to pay, as and when Rent is due and payable hereunder, the Undisputed Rent until such time as the dispute is resolved by agreement between the Parties or by arbitration pursuant to Section 13.7.

(a) Base Rent: Lessee will pay Lessor an amount of base rent equal to the amount set forth on the then-effective Rent Supplement, which shall be payable monthly in arrears 45 days after the conclusion of the month. The amount of base rent owed pursuant to this Section 3.1(a) may be supplemented by the Parties from time to time in accordance with Section 3.2. The amount of base rent payable pursuant to this Section 3.1(a), as supplemented from time to time pursuant to Section 3.2, is referred to as “Base Rent.”

(b) Percentage Rent: In addition to the Base Rent set forth above, Lessee covenants and agrees to pay to Lessor, as percentage rent, an annual amount equal to the percent of Gross Revenues during the applicable Lease Year in excess of the Annual Percentage Rent Breakpoint for such Lease Year, all as set forth on the then-effective Rent Supplement. The percentage amounts used for the calculation of percentage rent owed pursuant to this Section 3.1(b) (the “Percentage Rent Percentages”) may be supplemented by the Parties from time to time in accordance with Section 3.2 to account for additions to the ERCOT Transmission Assets. The percentage rent payable pursuant to this Section 3.1(b), as supplemented from time to time pursuant to Section 3.2, is referred to as “Percentage Rent.”

(c) Percentage Rent Breakpoints: With respect to the Annual Percentage Rent Breakpoint for each Lease Year: (1) the “First Lease Quarter Percentage Rent Breakpoint” shall be 25% of the Annual Percentage Rent Breakpoint for such Lease Year; (2) the “Second Lease Quarter Percentage Rent Breakpoint” shall be 50% of the Annual Percentage Rent Breakpoint for such Lease Year; and (3) the “Third Lease Quarter Percentage Rent Breakpoint” shall be 75% of the Annual Percentage Rent Breakpoint for such Lease Year.

(d) Gross Revenues:

(i) As used in this Agreement, subject to Section 3.1(d)(ii), the “Gross Revenues” of the ERCOT Transmission Assets shall mean and include all fees, charges and other revenues generated by or otherwise (x) received by or payable to Lessee in connection with or which are the result of the operation of the ERCOT Transmission Assets (and any assets related to the ERCOT Transmission Assets owned by Lessee), as set forth in the FERC Uniform System of Accounts for electric utilities or such other accounts as may be applicable from time to time in which Lessee records its revenues from operation of the ERCOT Transmission Assets; (y) received by or payable to Lessee from other opportunities and uses of the ERCOT Transmission

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

Assets pursuant to Section 1.2 hereof; or (z) that are insurance proceeds for business income lost from an insured event related to the ERCOT Transmission Assets; provided that, “Gross Revenues” shall not include (1) any payment received by Lessee as CIAC; (2) any items which are of a pure pass-through nature where such items are charged to and collected from customers of Lessee but which carry regulatory responsibility to remit such collections without offset or deduction to a third party, including, but not limited to, items such as: (A) sales taxes or other charges collected by Lessee on behalf of a taxing authority; (B) fees, charges and other revenues collected by Lessee that can be specifically traced to any regulatory approved costs incurred by Lessee that have been ordered or permitted by the PUCT to be recovered through Lessee’s rates such as system benefit funds; (C) fees, charges and other revenues collected by Lessee that can be specifically traced to any deferred costs funded by Lessee that have been ordered or permitted by the PUCT to be recovered through a tariff rider; and (D) such other items that Lessor and Lessee agree to in good faith are consistent with the foregoing and should be included prospectively in the list set forth in this clause (2) and in the event the Lessor and Lessee cannot agree on what items should be included on such list after 60 days of negotiating in good faith, then either Lessor or Lessee may submit such matter to arbitration pursuant to Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine which such items shall be included on such list, based on submissions by each of the Lessee and the Lessor; and (3) Revenues Attributable to Lessee CapEx. The term “Unadjusted Gross Revenues” means the amount of Gross Revenue, calculated in accordance with this Section 3.1(d)(i), without giving effect to the offset set forth in clause 3 above, related to Revenues Attributable to Lessee CapEx.

(ii) Except as set forth below, all ERCOT Transmission Revenues will be allocated to the ERCOT Transmission Assets covered by this Agreement based upon the following formula: Multiply (x) total ERCOT Transmission Revenues received by Lessee by (y) a fraction, the numerator of which is the Transmission Net Plant in Service for the ERCOT Transmission Assets covered by this Agreement and the denominator of which is the total Transmission Net Plant in Service for all regulated electric transmission systems owned by Lessor or an affiliate thereof and operated by Lessee or a subsidiary thereof within ERCOT (the “TCOS Allocation”). As of the Effective Date, all regulated electric transmission systems operated by Lessee or a subsidiary thereof within ERCOT are owned by Lessor or a subsidiary or parent entity thereof. As long as that is the case, Transmission Net Plant in Service and Transmission Gross Plant in service shall be derived exclusively from the financial statements of Lessor and agreed to by Lessee. If Lessee operates any electric transmission systems within ERCOT that are not leased from Lessor or an affiliate thereof, then the Parties will negotiate in good faith an equitable and appropriate mechanism for allocating ERCOT Transmission Revenues based on the Transmission Net Plant in Service of the respective electric transmission systems and in the event the Parties cannot agree on an equitable and appropriate mechanism after 60 days of negotiating in good faith, then either Party may submit such matter to arbitration pursuant to Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine such equitable and appropriate TCOS mechanism, based on submissions by each of the Lessee and the Lessor. The most recent TCOS Allocation agreed to by Lessor and Lessee will govern the allocation described in this Section 3.1(d)(ii), which TCOS Allocation may be set forth in a Rent Supplement but will not be required to be included in a Rent Supplement to be effective. Either Party may request a revision to such TCOS Allocation, based on the most recent available monthly balance sheet, no more frequently than once every sixty (60) days or in

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

connection with any Rent Supplement or Rent Validation executed and delivered by the Parties. If the Parties are unable to agree to an allocation, such matter will be submitted to arbitration pursuant to Section 13.7. “Gross Revenues,” for purposes hereof, will consist of the amount of such ERCOT Transmission Revenues allocated to the ERCOT Transmission Assets pursuant to this Section 3.1(d)(ii), plus any other amounts that constitute Gross Revenues pursuant hereto, minus Revenues Attributable to Lessee CapEx. As of the date hereof, the Parties do not expect that any Lessee Revenue, other than ERCOT Transmission Revenues, will be allocated to the ERCOT Transmission Assets and constitute Gross Revenues hereunder.

(iii) The Parties contemplate that there may be Capital Expenditures for assets that are placed in service and that are related and fairly allocable to the ERCOT Transmission Assets and are classified as Lessee CapEx. Unless the Parties agree otherwise based on appropriate factors at the time of the negotiation, Capital Expenditures that qualify as Lessee CapEx will qualify as Lessee CapEx on the date that the assets developed with such Capital Expenditures are placed in service. In such a case, Revenues Attributable to Lessee CapEx shall be determined and such portion shall be subtracted from Unadjusted Gross Revenues in order to calculate Gross Revenues. For these purposes, Revenues Attributable to Lessee CapEx shall be targeted to equal that portion of the Unadjusted Gross Revenues collected by Lessee which equals the amount needed to provide Lessee with the equivalent of a Comparable Rate of Return on any such Lessee CapEx (except that, in determining such Comparable Rate of Return, the Parties will not consider Lessee’s creditworthiness and there will be no Agreed-to-Discount). It is understood and agreed that such determinations of the Revenues Attributable to Lessee CapEx are intended to provide an accurate and reasonably administrable means of ensuring that the Lessee (and not the Lessor) will receive a Comparable Rate of Return attributable to the capital invested by Lessee in the Lessee CapEx. The Revenues Attributable to Lessee CapEx shall be determined solely to provide a Comparable Rate of Return on such Lessee CapEx and shall not be determined with reference to, or with any intention to true up, the effect of any difference between the initially anticipated and the actual return of or on prior Lessee CapEx. The Parties understand that there may be Capital Expenditures that relate to both the ERCOT Transmission Assets and to other transmission and/or distribution systems owned or operated by Lessee or an affiliate thereof, and, in such circumstance, the Parties will negotiate in good faith to determine the portion of such Capital Expenditures that constitute Lessee CapEx hereunder and in the event the Parties cannot determine such portion after 60 days of negotiating in good faith, then either Party may submit such matter to arbitration pursuant to Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine such portion of Capital Expenditures that constitute Lessee CapEx hereunder, based on submissions by each of the Lessee and the Lessor. Lessee agrees to provide Lessor with sufficient information regarding Lessee CapEx so that Lessor can monitor amounts actually spent on Lessee CapEx. If Lessee expects there will be any Lessee CapEx, Lessee may request, no more frequently than annually, that the Parties determine the Revenues Attributable to Lessee CapEx which relate to such Lessee CapEx for each subsequent Lease Year. Lessee will use reasonable efforts to make such request coincide with a Rent Supplement pursuant to Section 3.2(a). Each supplement and related determination of Revenues Attributable to Lessee CapEx for any Lease Year which is specified in this Section 3.1(d)(iii) shall be memorialized in the manner specified in Section 3.2(b).

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(e) Payment of Percentage Rent: Percentage Rent shall be paid by Lessee to Lessor not later than the date forty-five (45) days after the end of each Lease Quarter as herein provided. Lessee shall record Gross Revenues in order to provide an audit trail for the Gross Revenues. Lessee shall deliver a written statement to Lessor, accompanied by a CFO Certificate, within forty-five (45) days after the end of each Lease Quarter, stating (1) the Gross Revenues for that Lease Quarter, (2) the cumulative total through the end of that Lease Quarter of Gross Revenues for such Lease Year, (3) the Percentage Rent Breakpoint (the First Lease Quarter Percentage Rent Breakpoint, the Second Lease Quarter Percentage Rent Breakpoint, the Third Lease Quarter Percentage Rent Breakpoint or the Annual Percentage Rent Breakpoint for such Lease Year, as applicable), utilized by Lessee and applicable to Lessee’s calculation of Percentage Rent through the end of that Lease Quarter, and (4) the cumulative total of any Percentage Rent then due and the cumulative total of any Percentage Rent previously paid with respect to any prior Lease Quarter(s) within such Lease Year. If such CFO Certificate indicates that any Percentage Rent is due for such Lease Quarter (or such Lease Year, as applicable), based upon the cumulative total of Gross Revenues through the end of such Lease Quarter and the applicable Percentage Rent Breakpoint reflected in such statement, then Lessee shall pay and deliver any Percentage Rent then due with the statement and CFO Certificate for such Lease Quarter (or such Lease Year, as applicable). With respect to the final Percentage Rent calculation for any Lease Year, Lessee shall receive a credit for any Percentage Rent previously paid with respect to such Lease Year. If the Percentage Rent payments previously made by Lessee to Lessor for the first three Lease Quarters of a Lease Year, on a cumulative basis, exceed the annual amount of Percentage Rent payable by Lessee to Lessor for such Lease Year, then Lessee shall receive a credit for such excess amount against the next Percentage Rent payment(s) becoming due and payable by Lessee to Lessor under this Agreement. All statements deliverable by Lessee to Lessor under this Agreement shall be delivered to the place where rent is then payable, or to such other place or places as Lessor may from time to time direct by written notice to Lessee.

3.2. Rent Supplements.

(a) The Parties have executed a Rent Supplement with respect to the Rent in effect as of the Effective Date. This Section 3.2(a) will not require any amendment to Rent unless the Parties expect Incremental CapEx and the Parties have not previously entered into a Rent Supplement with respect to such Incremental CapEx. If the Parties expect Incremental CapEx, then they will negotiate in good faith to supplement Rent and other matters in accordance with this Section 3.2. In connection therewith, the Parties will negotiate the pre-tax rate of return that Lessor should earn on such Incremental CapEx, which will be based generally on an agreed-to-discount from the rate of return that public utility companies generally earn in the State of Texas at the time of such Rent Supplement negotiation, adjusted in the manner agreed to by the Parties (if justified) to take into account the creditworthiness of Lessee at the time of such Rent Supplement negotiation (the “Agreed-to-Discount”). Such discount will be based on the comparable discount agreed to in connection with the negotiation of rent pursuant to the McAllen Lease and other leases between Lessee and Lessor (or an affiliate thereof), as modified to take in to account appropriate factors at the time of such Rent Supplement negotiation. Such pre-tax rate of return, as determined in accordance with this paragraph, is referred to as a “Comparable Rate of Return.” The following will apply to the determination of the matters set forth on the Supplement:

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(i) The Parties will supplement Base Rent and Percentage Rent in a manner intended to provide a Comparable Rate of Return for Lessor on its Incremental CapEx. Such Comparable Rate of Return will be achieved by a split between Base Rent and Percentage Rent in the proportions requested by Lessor and agreed to by Lessee.

(ii) Unless the Parties agree otherwise based on appropriate factors at the time of the negotiation, Capital Expenditures will qualify as Incremental CapEx on the date such Capital Expenditures are placed in service, which differentiates these Capital Expenditures from the Capital Expenditures included in CapEx Budgets pursuant to Article X, which are measured under this Agreement based on the date the related Capital Expenditures are incurred.

(iii) Notwithstanding anything herein to the contrary, such supplement shall be determined solely to provide a Comparable Rate of Return on such Incremental CapEx and shall not be determined with reference to, or with any intention to true up, the effect of any difference between the initially anticipated and the actual return of or on, or the Base Rent or Percentage Rent payable with respect to, the ERCOT Transmission Assets as in place prior to the additions resulting from such Incremental CapEx.

(b) The Parties will memorialize the results of all Incremental CapEx supplements and Lessee CapEx supplement negotiations by executing and delivering a Rent Supplement, which will set forth the amount of contemplated Incremental CapEx, new Base Rent, a new Percentage Rent Schedule, new Revenues Attributable to Lessee CapEx, Lessee CapEx, new TCOS Allocation (if applicable), the effective date on which such changes will occur and the term of such Rent Supplement (if applicable). In no event will any new Base Rent or new Percentage Rent be payable, or any Revenues Attributable to Lessee CapEx be taken into account as a reduction to Unadjusted Gross Revenues, before the assets funded by the related Incremental CapEx or Lessee CapEx are placed in service. The Rent Supplement may also include the projected in-service date of the Incremental CapEx or Lessee CapEx to which the Rent Supplement applies. Upon execution and delivery of any such Rent Supplement, this Agreement will be deemed amended thereby. If necessary, the applicable Rent Supplement will include a description of the new assets to be funded by the Incremental CapEx. The Rent Supplement shall have the term set forth therein, not to extend past the then-current Term of this Agreement. At the end of the term of each Rent Supplement, the Parties shall negotiate a new Rent Supplement for the Lessee CapEx and Incremental CapEx covered by such prior Rent Supplement using the Comparable Rate of Return methodology set forth in Sections 3.1(d)(iii) and 3.2(a). Notwithstanding the foregoing, the Percentage Rent Percentages and Annual Percentage Rent Breakpoints reflected on such new Rent Supplement with respect to the Rate Base covered by such prior Rent Supplement shall be as set forth on the Percentage Rent Schedule of such prior Rent Supplement.

(c) If following a Rent Supplement there is a difference in (i) the amount of actual Incremental CapEx compared to the amount contemplated by the then-effective Rent Supplement, (ii) the amount of actual Lessee CapEx compared to the amount contemplated by the then-effective Rent Supplement, or (iii) the placed-in-service date of such Incremental CapEx or Lessee CapEx compared to what was contemplated at the time of the then-effective Rent Supplement then, at any time within two years of the date the Parties agree to a Rent

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

Supplement, either Party may request a Rent Validation. If there has been such a difference, the Parties will supplement Incremental CapEx, Base Rent, Percentage Rent Percentages, Annual Percentage Rent Breakpoints, Revenues Attributable to Lessee CapEx, and/or Lessee CapEx, as applicable, to what they would have been, at the time of the Rent Supplement, to reflect (1) the amount of actual Incremental CapEx and Lessee CapEx and/or (2) the actual dates such Incremental CapEx and/or Lessee CapEx was placed in service, but keeping fixed all other relevant assumptions and inputs, including the Comparable Rate of Return. For the avoidance of doubt, in no circumstance will a Rent Validation occur to account for any difference between the initially anticipated and the actual return of or on the Incremental CapEx and/or Lessee CapEx, and no such difference will be taken into account as part of such Rent Validation. The Parties also will negotiate in good faith to determine (A) whether one Party should make a lump sum payment to the other Party as a result of excess or deficient Rent Lessee paid, prior to the date of the effective date of the Rent Validation, in connection with the Rent Supplement, and, (B) if applicable, the amount of any such lump sum payment. The Parties will memorialize the result of any Rent Validation negotiation by executing and delivering a revised Rent Supplement, which will set forth revised expected Incremental CapEx, Lessee CapEx, Base Rent, Percentage Rent Percentages, Annual Percentage Rent Breakpoints, and/or Revenues Attributable to Lessee CapEx, as applicable, the effective date on which such changes will occur and, if applicable, the amount of the lump sum payment that one Party must make to the other Party (which payment must be made within 30 days of the execution and delivery of such revised Rent Supplement). Any lump sum payments received by Lessor under this Section 3.2(c) shall be treated as Rent by the Parties. Upon execution and delivery of any such Rent Validation, this Agreement will be deemed amended thereby. The Parties will reasonably cooperate to minimize the number of Rent Validations, and prospective Rent Supplements and Rent Validations may be combined into one revised, amended and restated Rent Supplement.

(d) In connection with the foregoing provisions of this Section 3.2, Lessor and Lessee shall use good faith efforts to agree to a Rent Supplement, renewal of a Rent Supplement or Rent Validation, as applicable, within 60 days of a request therefor by either Party. If, by the end of such 60 day period, Lessee and Lessor cannot in good faith agree to the terms of a Rent Supplement, renewal of a Rent Supplement or Rent Validation, such dispute shall be submitted to arbitration in accordance with Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine the terms of such Rent Supplement, renewal of a Rent Supplement or Rent Validation (including any lump sum payment amount), based on submissions by each of the Lessee and the Lessor.

3.3. Confirmation of Percentage Rent.

(a) In the event that Lessee determines that the Percentage Rent paid with respect to any Lease Year exceeded the amount of Percentage Rent actually due for such Lease Year (such overage being the “Excess Percentage Rent”), Lessee shall promptly notify Lessor of such fact and shall deliver a new CFO Certificate (the “Revised Certificate”) setting forth the corrected calculations of the Percentage Rent due for such Lease Year and identifying the amount of the Excess Percentage Rent. Upon Lessor’s reasonable verification of the information set forth in the Revised Certificate, Lessor shall refund to Lessee the Excess Percentage Rent. Notwithstanding anything to the contrary contained herein, in no event shall Lessor have any obligation under this Section 3.3(a) to refund any Excess Percentage Rent if Lessor has not received the Revised Certificate by March 31 of the year following the Lease Year for which the Excess Percentage Rent was paid.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(b) Lessee shall utilize, or cause to be utilized, an accounting system for the ERCOT Transmission Assets in accordance with the FERC Uniform System of Accounts for electric utilities, that will accurately record all data necessary to compute Percentage Rent, and Lessee shall retain and shall allow Lessor and its representatives to have reasonable access to, for at least five (5) years after the expiration of each Lease Year, reasonably adequate records conforming to such accounting system showing all data necessary to conduct Lessor’s Audit and to compute Percentage Rent for the applicable Lease Years and to otherwise file or defend tax returns and reports to any Regulatory Authority.

(c) Lessor shall have the right from time to time to cause its accountants or representatives to conduct an inspection, examination and/or audit (a “Lessor’s Audit”) of all of Lessee’s records, including supporting data, sales and excise tax returns and the records described in Section 3.3(b), reasonably required to complete such Lessor’s Audit and to verify Percentage Rent, subject to any prohibitions or limitations on disclosure of any such data under applicable laws, regulations and governmental requirements. If any Lessor’s Audit discloses a deficiency in the payment of Percentage Rent, and either Lessee agrees with the result of Lessor’s Audit or the matter is otherwise determined or compromised, Lessee shall forthwith pay to Lessor the amount of the deficiency, as finally agreed or determined, together with interest at the Overdue Rate from the date when said payment should have been made to the date of payment thereof. In addition to the amounts described above in this Section 3.3(c), if any Lessor’s Audit discloses a deficiency in the payment of Percentage Rent which, as finally agreed or determined, exceeds 3% of the amount paid, Lessee shall pay the costs of Lessor’s Audit. In no event shall Lessor undertake a Lessor’s Audit after March 31 of the second year following the Lease Year for which such audit is requested.

(d) Any proprietary information obtained by Lessor pursuant to the provisions of this Section 3.3 shall be treated as confidential, except that such information may be used, subject to appropriate confidentiality safeguards, in any litigation or arbitration between the Parties and except further that Lessor may disclose such information to lenders and investors, including prospective lenders or investors and to any other persons to whom disclosure is necessary or appropriate to comply with applicable laws, regulations and governmental requirements and to comply with any reporting requirements applicable to Lessor or Lessee under any applicable securities laws or regulations or any listing requirements of any applicable securities exchange.

(e) The obligations of Lessee and Lessor contained in this Section 3.3 shall survive the expiration or earlier termination of this Agreement. Any dispute as to the existence or amount of any deficiency in the payment of Percentage Rent as disclosed by Lessor’s Audit shall, if not otherwise settled by the Parties, be submitted to arbitration pursuant to the provisions of Section 13.7.

3.4. Additional Rent. In addition to Base Rent and Percentage Rent, Lessee also will pay and discharge as and when due and payable all other amounts, liabilities, obligations and impositions that Lessee assumes or agrees to pay under this Agreement, including without limitation, the expenses described in Section 1.3 and any reimbursement for such amounts and other damages to Lessor in the event that Lessor pays such expenses or performs such obligations on behalf of Lessee (collectively, “Additional Rent”).

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

3.5. No Set Off. Rent shall be paid to Lessor without set off, deduction or counterclaim; provided, however, that Lessee shall have the right to assert any claim or counterclaim in a separate action brought by Lessee under this Agreement or to assert any mandatory counterclaim in any action brought by Lessor under this Agreement.

3.6. Late Payment Penalty. If Lessee fails to make any payment of Rent to Lessor within five (5) days after it is due, interest shall accrue on the overdue amount, from the date overdue until the date paid, at the Overdue Rate.

3.7. Credit Support. If Lessor has reasonable grounds for insecurity regarding the performance of Lessee’s obligations hereunder, Lessor may require Lessee to provide credit support in the amount, form and for the term reasonably acceptable to Lessor, including but not limited to, a letter of credit, a prepayment, or a guaranty.

3.8. Other Revenue. If Lessee receives or expects to receive any fees, charges or Other Revenue and other than de minimis amounts not to exceed $100,000 in any calendar year, then, unless Lessee reasonably believes that such Other Revenue will not operate to reduce Lessee’s tariff within the State of Texas, Lessee and Lessor will negotiate in good faith to amend this Agreement or a similar lease to characterize the portion of such Other Revenue which Lessor reasonably expects will operate to reduce Lessee’s tariff within the State of Texas as Unadjusted Gross Revenue hereunder or under such other similar lease. In the event the Lessee and Lessor cannot agree on the terms of such amendment of this Agreement or of a similar lease after 60 days of negotiating in good faith, then either the Lessee or the Lessor may submit such matters to arbitration pursuant to Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to characterize the portion of such Other Revenue which Lessor reasonably expects will operate to reduce Lessee’s tariff within the State of Texas as Unadjusted Gross Revenue hereunder or under such other similar lease, based on submissions by each of the Lessee and the Lessor.

ARTICLE IV

LESSEE’S REPRESENTATIONS, WARRANTIES AND COVENANTS

Lessee hereby represents, warrants and covenants to Lessor that:

4.1. Maintenance, Operation and Repair of the ERCOT Transmission Assets.

(a) Lessee, at its own cost and expense, shall maintain (including both scheduled and unscheduled maintenance), operate, repair and make all modifications (other than Footprint Projects) to the ERCOT Transmission Assets and any components thereof (whether owned by Lessor or Lessee), including directing all operations of and supplying all personnel necessary for the operation of the ERCOT Transmission Assets, in each case, as reasonable and prudent and consistent with Good Utility Practice and as required by Applicable Law. Lessee shall carry out all obligations under this Agreement as reasonable and prudent and consistent with Good Utility Practice and in accordance with manufacturers’ warranty requirements (during any applicable warranty period) and the Lessee’s established operating procedures and maintenance, rebuild and

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

repair programs so as to keep the ERCOT Transmission Assets in good working order, ordinary wear and tear excepted, and in such condition as shall comply in all material respects with all Applicable Laws. Lessee will operate the ERCOT Transmission Assets in a reliable and safe manner in compliance with all applicable requirements and regulations of Regulatory Authorities. Lessee will not operate the ERCOT Transmission Assets or any component thereof in any manner excluded from coverage by any insurance in effect as required by the terms hereof.

(b) If inspections of the ERCOT Transmission Assets by Lessor show that the ERCOT Transmission Assets do not meet industry standards or Good Utility Practice for maintenance and repair and/or fail to meet the requirements of any Applicable Law, Lessee shall promptly, but in any event within thirty (30) days after such initial notification, (i) develop a plan for Lessor’s review by which the ERCOT Transmission Assets can be modified to comply with the standards, and (ii) complete any and all such modifications consistent with all applicable reliability and safety standards established by regulations, orders or requirements of Regulatory Authorities.

4.2. Licenses and Permits. Lessee shall obtain and maintain any and all licenses, permits and other governmental and third-party consents and approvals required by Applicable Law in order to carry out its obligations under this Agreement.

4.3. Property Taxes, and other Assessments and Fees. Lessee shall bear and timely pay all ad valorem or property taxes, sales and use taxes, or other assessments, governmental charges or fees that shall or may during the Term be imposed on, or arise in connection with, the repair, maintenance or operation of the ERCOT Transmission Assets (including all Footprint Projects as described and provided for in Section 10.1 of this Agreement) (“Lessee Taxes”); provided that Lessee shall not be obligated to pay any net income taxes imposed upon Lessor or any sales and use taxes which arise in connection with Lessor’s acquisition of Footprint Projects (“Lessor Taxes”). Upon the written request by Lessor, Lessee shall provide Lessor with evidence of the payment of any such Lessee Taxes, the failure of which to be paid would cause the imposition of a Lien upon the ERCOT Transmission Assets or any component thereof or interest therein. Lessee shall assume full responsibility for preparing and furnishing to Lessor for execution all filings with any governmental authority of or in the state and/or locality in which the ERCOT Transmission Assets is located in respect of any and all taxes; except that, where required or permitted by Applicable Law, Lessee shall make such filings on behalf of Lessor in the name of Lessor or in Lessee’s own name. In each case in which Lessee furnishes a tax return or any other form to be executed by Lessor for filing with or delivery to any taxing authority, Lessee shall certify to Lessor that such document is in the proper form, is required to be filed under Applicable Law and does not impose any tax or other liability on Lessor or any of its affiliates which is not indemnified by Lessee. Lessee shall be permitted to contest, in its own name when permitted by law but otherwise on behalf of Lessor, in good faith and upon consultation with Lessor, any taxes it is obligated to pay hereunder.

4.4. Requirements of Governmental Agencies and Regulatory Authorities. Lessee, at its expense, shall comply with all Applicable Laws, including without limitation all requirements of the Regulatory Authorities. Lessee shall have the right, in its reasonable discretion and at its cost and expense, to contest by appropriate legal proceedings, the validity or

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

applicability to the ERCOT Transmission Assets of any Applicable Law made or issued by any federal, state, county, local or other governmental agency or entity. Any such contest or proceeding shall be controlled and directed by Lessee. Notwithstanding the foregoing, Lessee shall provide Lessor written notice of the commencement and, at reasonable intervals after commencement, the progress of any such legal proceedings.

4.5. Liens. Lessee shall keep the ERCOT Transmission Assets free and clear of all Liens other than Permitted Liens; provided, however, that if Lessee wishes to contest any such Lien (other than a Permitted Lien), Lessee shall, promptly, and in any event within thirty (30) days after it receives notice of the filing of such Lien, remove or bond over such lien from the ERCOT Transmission Assets pursuant to Applicable Law. If Lessee fails to promptly remove or bond over any such Lien, Lessor may, after providing notice to Lessee, take reasonable action to satisfy, defend, settle or otherwise remove the Lien at Lessee’s expense.

4.6. Hazardous Materials.

(a) Lessee shall operate and maintain the ERCOT Transmission Assets and conduct all of its other activities in respect thereof in compliance in all material respects with any Applicable Laws relating to air, water, land and the generation, storage, use, handling, transportation, treatment or disposal of Hazardous Materials. Lessee shall promptly notify Lessor of any such violation and, to the extent Lessee becomes aware of any environmental, health, safety or security matter that requires a corrective action, Lessee shall, in consultation with Lessor, undertake and complete such corrective action. Lessee shall have the obligation to report any such violations to the appropriate Regulatory Authorities in accordance with Applicable Law and, if practicable, shall give notice thereof to Lessor prior to making such report.

(b) Without limiting the generality of the foregoing, Lessee shall not (i) place or locate any underground tanks on the property underlying the ERCOT Transmission Assets, (ii) generate, manufacture, transport, produce, use, treat, store, release, dispose of or otherwise deposit Hazardous Materials in or on the ERCOT Transmission Assets, the property underlying the ERCOT Transmission Assets or any portion thereof other than as permitted by Applicable Laws that govern the same or are applicable thereto, (iii) permit any other substances, materials or conditions in, on or emanating from the ERCOT Transmission Assets, the property underlying the ERCOT Transmission Assets or any portion thereof which may support a claim or cause of action under any Applicable Law or (iv) undertake any action that would reasonably be expected to cause an unauthorized release of Hazardous Materials at the property underlying the ERCOT Transmission Assets.

(c) Lessee shall periodically, at intervals determined in its reasonable discretion in accordance with Good Utility Practice or as required by Applicable Law, at Lessee’s sole expense, conduct inspections of all components of the ERCOT Transmission Assets and the ERCOT Transmission Assets property to ensure compliance with Applicable Laws and with this Section 4.6, and shall promptly notify Lessor of the results of any such inspections. Lessor may, at Lessor’s expense, conduct its own testing at times determined in its reasonable discretion, and after reasonable consultation with Lessee, to ensure Lessee’s compliance with Applicable Laws and with this Section 4.6, provided, however, that Lessor agrees to indemnify Lessee, in accordance with Section 12.2, from and against any and all Claims arising from such testing.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

4.7. Indebtedness. Lessee shall not incur Indebtedness other than: (i) Indebtedness in an aggregate principal amount of up to the greater of (A) $5,000,000 and (B) an amount equal to one percent (1%) of the sum of, without duplication, (x) the total amount of the Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus (z) the total amount of Leased Consolidated Net Plant of Lessee, in each case on a senior secured basis, (ii) Indebtedness in an aggregate principal amount of up to the greater of (A) $10,000,000 and (B) an amount equal to one-and-a-half percent (1.5%) of the sum of, without duplication, (x) the total amount of the Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus (z) the total amount of Leased Consolidated Net Plant of Lessee, in each case on an unsecured subordinated basis on terms substantially similar to the terms set forth on Exhibit A and (iii) loans, in an aggregate principal amount not to exceed $10,000,000 at any time outstanding, made by InfraREIT Partners, LP or a subsidiary thereof to Lessee from time to time for the purpose of financing capital expenditures. For purposes of clauses (i) and (ii) of the preceding sentence, any Consolidated Qualified Lessees of Lessee will be treated as Lessee. In addition to the foregoing, any of Lessee’s subsidiaries may incur Indebtedness in an aggregate principal amount of up to the product of (x) Lessee’s aggregate Consolidated Net Plant multiplied by (y) the lesser of (A) the sum of Lessee’s then-current PUCT-regulated debt-to-equity ratio (expressed as a percentage) and five percent (5%) or (B) sixty-five percent (65%); provided, however, that such Indebtedness must be Non-Recourse Debt to Lessee. For purposes of this Section 4.7, Lessee’s Consolidated Net Plant will be derived from its most recently prepared consolidated balance sheet, prepared in accordance with GAAP but adjusted to reverse the effects of failed sale-leaseback accounting in a manner reasonably determined by Lessee in good faith. Without limiting the amount of Indebtedness permitted by the foregoing, Lessee may also incur Indebtedness (x) in the form of a pledge of equity interests in a subsidiary of Lessee as security for Non-Recourse Debt of such subsidiary and (y) in amounts otherwise permitted under the Debt Agreements.

4.8. Records. In addition to the records referred to in Section 3.3, Lessee shall maintain proper books of record and account in conformity with GAAP and all applicable Regulatory Authorities and each other governmental agency or authority having legal or regulatory jurisdiction over Lessee. Additionally, Lessee shall maintain or cause to be maintained all logs, drawings, manuals, specifications and data and inspection, modification and maintenance records and other materials required to be maintained in respect of the ERCOT Transmission Assets by Applicable Laws or by prudent and Good Utility Practice. Lessee shall allow Lessor and its representatives to have reasonable access to, for at least five (5) years after the expiration of each Lease Year, the records referred to in this Section 4.8.

4.9. Surrender. Upon expiration or earlier termination of this Agreement in accordance with its terms (but subject to Section 2.2 and the requirements of all Applicable Laws), and in a manner calculated to avoid any disruption of electrical service, Lessee shall vacate and surrender possession of all components of the ERCOT Transmission Assets (other than in respect of Footprint Projects funded by Lessee as described in Section 10.5(a)) to Lessor,

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

or to such other person or entity as Lessor may direct. At the time of such surrender, the ERCOT Transmission Assets shall be free and clear of Liens and other rights of third parties (other than Permitted Liens), and shall be in the same condition as on the Effective Date, ordinary wear and tear and subsequent Footprint Projects excepted. Lessee shall deliver or cause to be delivered to Lessor, or to such other person or entity as Lessor may direct, copies of all title documents, logs, drawings, manuals, specifications and data and inspection, modification and maintenance records, billing records, reports and other documents in respect of the ERCOT Transmission Assets which are necessary to determine the condition of the ERCOT Transmission Assets or for the continued maintenance, repair or general operation of the ERCOT Transmission Assets and are in Lessee’s possession at such time. In connection with the surrender of the ERCOT Transmission Assets, Lessor shall pay to Lessee the aggregate purchase price for any Footprint Projects, equipment or other property purchased by Lessor in accordance with Section 2.3 or Section 10.5(b).

4.10. Cooperation; Transition Services.

(a) During the period after notice of termination and prior to the termination of the Agreement, with reasonable notice, Lessee will cooperate in all reasonable respects with the efforts of Lessor to sell or lease the ERCOT Transmission Assets (or any component thereof) or any interest therein, including, without limitation, permitting prospective purchasers or lessees to fully inspect the ERCOT Transmission Assets and any logs, drawings, manuals, specifications, data and maintenance records relating thereto; provided, that such cooperation shall not unreasonably interfere with the normal operation of the ERCOT Transmission Assets or cause Lessee to incur any additional expenses other than as specifically provided herein. All information obtained in connection with such inspection shall be subject to confidentiality requirements at least as restrictive as those contained in Section 13.3.

(b) Upon expiration or termination of this Agreement, Lessee shall continue to lease and operate the ERCOT Transmission Assets pursuant to the terms of Section 2.2, if required thereunder. During such period Lessee shall perform all duties and retain all obligations under Article IV in all respects, as if the Agreement had not expired or been terminated.

4.11. Lessee’s Authority. Lessee has all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder. Lessee has taken all action necessary to execute and deliver this Agreement and to perform its obligations hereunder, and no other action or proceeding on the part of Lessee is necessary to authorize this Agreement. This Agreement constitutes the legally valid and binding obligation of Lessee, enforceable against Lessee in accordance with its terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar Applicable Laws affecting the enforcement of creditors’ rights generally and equitable principles.

4.12. Litigation. If Lessee becomes aware of any actions, claims or other legal or administrative proceedings that are pending, threatened or anticipated with respect to, or which could materially and adversely affect, the ERCOT Transmission Assets, Lessee shall promptly deliver notice thereof to Lessor.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

4.13. Financing. Lessee acknowledges that Lessor has advised Lessee that Lessor has obtained financing secured by, among other things, the ERCOT Transmission Assets and this Agreement. In connection with such financing, Lessor made certain representations, warranties and covenants set forth in that certain (i) Amended and Restated Note Purchase Agreement entered into by Lessor and dated as of September 14, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “2009 Note Purchase Agreement”), a copy of which has been provided to and reviewed by Lessee, (ii) Amended and Restated Note Purchase Agreement entered into by Lessor and dated as of July 13, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “2010 Note Purchase Agreement” and, together with the 2009 Note Purchase Agreement, the “Note Purchase Agreements”), a copy of which has been provided to and reviewed by Lessee and (iii) Second Amended and Restated Credit Agreement entered into by Lessor and dated as of June 28, 2013 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement” and, together with the Note Purchase Agreements, the “Debt Agreements”), a copy of which has been provided to and reviewed by Lessee.

Lessor has taken all action necessary to execute and deliver this Agreement and to perform its obligations hereunder, and no other action or proceeding on the part of Lessor is necessary to authorize this Agreement. This Agreement constitutes the legally valid and binding obligation of Lessor, enforceable against Lessor in accordance with its terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar Applicable Laws affecting the enforcement of creditors’ rights generally and equitable principles.

5.2. Liens and Tenants. Lessor represents that Lessor has good and valid title to the ERCOT Transmission Assets, there are no unrecorded liens, encumbrances, leases, mortgages, deeds of trust (except as disclosed to Lessee in writing or as arise by operation of law), or other exceptions (collectively, “Liens”) arising as a result of any acts or omissions to act of Lessor by, through or under Lessor to Lessor’s right, title or interest in the ERCOT Transmission Assets other than any such of the foregoing that does not materially impair the Lessee’s use of the ERCOT Transmission Assets, and, to Lessor’s knowledge, there exist no rights or interests of any third party relating to the ERCOT Transmission Assets that are not contemplated herein. Except for Permitted Liens or as may be disclosed in the applicable real property records in the State of Texas, or as disclosed by Lessor in writing to Lessee, Lessor represents that there are no mortgages, deeds of trust, or similar liens or security interests encumbering all or any portion of the ERCOT Transmission Assets.

6.1. Loss and Damage to the ERCOT Transmission Assets.

(a) In the event of any damage or loss to any component of the ERCOT Transmission Assets, Lessee shall promptly repair or replace such component to the standards required by Section 4.1 (regardless of whether such repair or replacement constitutes a Repair or a Footprint Project). Any such repaired or replaced component will immediately become part of the ERCOT Transmission Assets owned by Lessor and the cost of any repair or replacement shall be borne as described in Sections 6.1(b)-(d) below.

(b) If such repair or replacement constitutes a Repair, the cost of repairing or replacing such damage or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessee. Lessee shall be entitled to retain any insurance proceeds in excess of the amount necessary in connection with such Repair.

(c) If such repair or replacement constitutes a Footprint Project, then, as long as the related costs have been included in a CapEx Budget, the cost of repairing or replacing such damage or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessor. In such circumstance, unless otherwise agreed by the Parties, (i) if the damage or loss is covered by insurance, Lessor shall be responsible for payment of any deductible, and (ii) any damage or loss not covered by insurance (exclusive of any deductible) shall be the responsibility of Lessor. If the sum of such deductible and insurance proceeds exceeds the cost of such Footprint Project, then such excess will first reduce Lessor’s obligation to fund the deductible hereunder, and any excess thereafter will be retained by Lessee. If such repair or replacement constitutes a Footprint Project that is not included in a CapEx Budget, the provisions of Article X shall apply.

(d) Lessee shall be solely responsible for all costs of repairing or replacing any damaged property and equipment that is not part of the ERCOT Transmission Assets and owned by Lessee, whether covered by Lessee’s insurance under Section 6.2 or otherwise. Nothing in this provision shall preclude Lessee from seeking recovery of such costs in a rate proceeding at the PUCT.

(e) If Lessor funds Lessee’s Personal Property pursuant to Section 10.1(b) of this Agreement, then all such funded Personal Property will be treated as a Footprint Project, and not a Repair, for purposes of this Section 6.1.

6.2. Insurance. Lessee will maintain, with financially sound and reputable insurers, insurance with respect to its business and properties and the ERCOT Transmission Assets against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated, but in no event less than the insurance set forth in this Section 6.2 and Exhibit B.

(a) Lessee shall procure at its own expense and maintain in full force and effect at all times throughout the term of this insurance policies with insurance companies rated A-, 8 or higher by A.M. Best or acceptable to Lessor if not so rated, and authorized to do business in the State of Texas.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(b) Lessor may at any time amend the requirements and approved insurance companies described in this Section 6.2 or Exhibit B due to (i) new information not previously known by Lessor prior to the date of this Agreement or (ii) changed circumstances after the date of this Agreement, which in the reasonable judgment of Lessor either renders a required coverage to be materially inadequate or materially reduces the financial ability of the approved insurance companies to pay claims.

(c) On the first Business Day of each year, and promptly at such other times as Lessor may reasonably request, Lessee shall furnish Lessor with approved certification of all required insurance. Such certification shall be executed by each insurer or by an authorized representative of each insurer where it is not practical for such insurer to execute the certificate itself. Such certification shall identify underwriters, the type of insurance, the insurance limits, and the policy term, and shall specifically list the special provisions enumerated for such insurance required by this Section 6.2. Upon request, Lessee will promptly furnish Lessor with copies of all insurance certificates, binders, and cover notes or other evidence of such insurance relating to the ERCOT Transmission Assets.

(d) Concurrently with the furnishing of the certification referred to in Section 6.2(c) and on an annual basis thereafter, Lessee shall furnish Lessor with a certificate, signed by an officer of Lessee, stating that all premiums then due have been paid and that the insurance then carried or to be renewed is in accordance with the terms of this Section 6.2. and Exhibit B.

(e) In the event Lessee fails to take out or maintain the full insurance coverage required by this Section 6.2 and Exhibit B, Lessor, upon thirty (30) days’ prior notice (unless the aforementioned insurance would lapse within such period, in which event notice should be given as soon as reasonably possible) to Lessee of any such failure, may (but shall not be obligated to) take out the required policies of insurance and pay the premiums on the same. All amounts so advanced thereof by Lessor shall become an additional obligation of Lessee to Lessor, and Lessee shall forthwith pay such amounts to Lessor.

(f) No provision of this Section 6.2 or Exhibit B or any other provision of this Agreement shall impose on Lessor any duty or obligation to verify the existence or adequacy of the insurance coverage maintained by Lessee, nor shall Lessor be responsible for any representations or warranties made by or on behalf of Lessee to any insurance company or underwriter.

ARTICLE VII

REPORTING

7.1. Private Financing Arrangements. Lessee understands that Lessor, or an affiliate thereof, has raised equity and debt capital secured by the ERCOT Transmission Assets and this Agreement and that Lessor or its affiliates have reporting obligations in connection with such arrangements, including obligations to provide financial statements prepared in accordance with GAAP, to prepare an annual strategic plan and to update such annual strategic plan in the event of certain material deviations therefrom. Lessee understands that Lessor relies on Lessee in order to comply with such obligations. From time to time, Lessor or an affiliate thereof may enter into additional arrangements that impose similar obligations. Accordingly, Lessee agrees

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

to provide Lessor in a timely manner audited year-end financial statements, quarterly unaudited financial statements for the first three quarters of each year (certified by a financial officer of Lessee), estimates of Percentage Rent, and such acknowledgements, certificates, permits, licenses, instruments, documents and other information as Lessor may reasonably request from time to time in connection with, or to enable Lessor and its affiliates to comply with any such debt or equity financing arrangements or with Applicable Law. The Parties will negotiate in good faith the time frames during which Lessee will provide such information, with the intention that Lessee provide such information in a manner that is not unduly burdensome but that also allows Lessor sufficient time to comply with its reporting obligations. Lessee will also cooperate with Lessor to enable Lessor to satisfy its obligations in respect of annual strategic plans, including providing Lessor with requested information in advance of the due date of such annual strategic plan and keeping Lessor apprised of deviations in capital expenditures, construction activity or revenues of Lessee from amounts that were originally provided by Lessee in preparing such annual strategic plan. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and to reasonably cooperate with Lessor to remedy the effects of such non-compliance.

7.2. Public Company and Regulatory Information and Cooperation.

(a) Lessee agrees to provide audited full-year and unaudited (but SAS 100 reviewed) interim financial statements and the consent of Lessee’s auditors to the inclusion of their opinion regarding such financial statements in filings with the Securities and Exchange Commission made by Lessor or an affiliate of Lessor. Lessor may also request that Lessee provide evidence of a SAS 100 review from Lessee’s auditors with respect to any unaudited interim financial statements included in any such filing. Lessor shall have the right to share any such financial statements with its lenders under the Debt Agreements. Lessee covenants that (i) such financial statements will fairly present in all material respects the financial condition, results of operations and cash flows of Lessee as of, and for, the periods presented, and (ii) Lessee will endeavor to cause such financial statements to comply with any applicable laws, rules or regulations that Lessee and Lessor conclude in good faith are applicable to such financial statements by virtue of their inclusion in the securities law filings of Lessor or an affiliate thereof.

(b) Lessee agrees that, in connection with any underwritten offering of the securities of Lessor or any affiliate thereof, Lessee will use commercially reasonable efforts to cause its auditors to provide a comfort letter (or its equivalent) to such underwriters, if requested by Lessor.

(c) Lessee agrees to cooperate with Lessor when Lessor or an affiliate provides estimates to analysts and or investors regarding Lessor’s expectations of its future operating results (including capital expenditures) and to cooperate with Lessor with respect to analysts and investors to the extent such expectations change in any material respect.

(d) Lessee and Lessor agree to reasonably cooperate to ensure that, to the extent they require information from the other party in order to prepare their financial statements, to obtain audits of those financial statements and, if required, of their internal control over financial reporting, to respond to comments of the Securities and Exchange Commission on such financial statements or statements related to internal control over financial reporting or disclosure controls

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

and procedures, or to ensure the efficacy of their internal controls or disclosure controls and procedures, they will reasonably cooperate in order to ensure that each Party is able to meet its obligations in respect thereof. Lessee agrees to promptly notify Lessor of or provide to Lessor, as applicable, (i) any material communication, written or otherwise, submitted to the Lessee by its auditors, including, but not limited to an audit response letter, accountant’s management letter or other written report submitted to Lessee by its accountants or any governmental agency in connection with an annual or interim audit of Lessee’s books, (ii) any material correspondence with, reports of or reports to any Regulatory Authority with respect to the ERCOT Transmission Assets and (iii) any notices of violations of Applicable Law with respect to the ERCOT Transmission Assets, in each case taking into account the REIT’s reporting obligations as a public company.

(e) Lessor agrees to inform Lessee of the time periods in which each of the items identified in this Section 7.2 will be required, which may change. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and to reasonably cooperate with Lessor to remedy the effects of such non-compliance.

(f) If Lessor identifies additional matters with respect to which Lessee input, assistance or information is required in order for Lessor and its affiliates to comply with any applicable securities laws, the rules or regulations of any exchange on which the securities of such affiliate are traded or any similar laws, rules or regulations, the Parties agree to cooperate and negotiate in good faith in order to determine the manner in which Lessee can provide such input, assistance or information in a manner that positions Lessor and its affiliates to comply in a timely manner with such laws, rules or regulations, as efficiently as is feasible so as to minimize the burden that the provision of such input, assistance or information imposes on Lessee.

7.3. Mutual Obligations. Each Party shall as promptly as reasonably practicable furnish or cause to be furnished to the other Party, upon request from such Party, such information as may be required to enable such Party to file any reports required to be filed with any governmental or Regulatory Authority due to such Party’s ownership interest in or operation and control of the ERCOT Transmission Assets, as applicable.

ARTICLE VIII

ASSIGNMENT

This Agreement shall not be assignable by either Party, nor shall the ERCOT Transmission Assets or any part thereof be subleased by Lessee, except with the prior written consent of the other Party and the prior approval of any Regulatory Authority whose approval is required for the effectiveness of such assignment or sublease. For purposes of this Article VIII, an “assignment” by Lessee shall mean and include, in addition to any direct transfer by Lessee to a third party of all or any part of Lessee’s rights, estate or interests under this Agreement, any direct or indirect, voluntary or involuntary transfer of or encumbrance on all or any part of Lessee’s rights, estate or interests under this Agreement (i) by operation of law and/or (ii) by direct or collateral transfer of all or any part of the legal or beneficial ownership interest in Lessee by merger, consolidation or otherwise, provided, in the case of clause (ii), any such transaction or transactions will only constitute an assignment hereunder to the extent they result

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

in a Change of Control. Notwithstanding the foregoing, Lessor shall have the right, without Lessee’s consent but subject to obtaining regulatory approval as described in the foregoing sentence, (a) to assign, pledge or grant a security interest in any or all of its interest in the Agreement to a lender or lenders, or a trustee acting on behalf of such lenders, in connection with a financing or refinancing in which such interest is pledged as collateral, and Lessee agrees to enter into such acknowledgments and agreements in respect thereof as the Lessor may reasonably request and (b) to assign its interest in this Agreement to a successor owner of the ERCOT Transmission Assets.

ARTICLE IX

DEFAULT

9.1. Lessee Default. Subject to Section 9.3, Lessee shall be in default in the event of any of the following:

(a) Except as provided in Section 9.1(g), Lessee’s failure to make any payment of Rent when due;

(b) Lessee (i) is generally not paying, or admits in writing its inability to pay, its debts as they become due, (ii) files, or consents by answer or otherwise to the filing against it of, a petition for relief or reorganization or arrangement or any other petition in bankruptcy, for liquidation or to take advantage of any bankruptcy, insolvency, reorganization, moratorium or other similar law of any jurisdiction, (iii) makes an assignment for the benefit of its creditors, (iv) consents to the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to it or with respect to any substantial part of its property, (v) is adjudicated as insolvent or to be liquidated, or (vi) takes corporate action for the purpose of any of the foregoing;

(d) Any representation or warranty made by Lessee herein shall prove to have been inaccurate in any material respect at the time made;

(e) a final judgment or judgments for the payment of money aggregating in excess of $1,000,000 are rendered against Lessee and which judgments are not, within 60 days after entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within 60 days after the expiration of such stay;

(f) Lessee shall have breached or failed to comply in any material respect with any other covenant or agreement contained herein; or

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(g) Notwithstanding Section 9.1(a), Lessee’s failure to pay Rent when due shall not constitute a default if (i) such failure is due to unforeseeable circumstances arising from a physical event beyond the control of the Lessee, including the incurrence of costs and expenditures as a result of such an event that are materially in excess of budgeted costs and expenditures or an unforeseen material decline in electricity usage as a result of such event and (ii) such failure is cured within ninety (90) days after the date such rent was due through Lessee’s payment of the entire amount of such unpaid Rent, plus interest thereon at a rate equal to six percent (6%) per annum or the maximum rate allowed by law, whichever is lesser, from the date such Rent was originally due until the date of payment.

9.2. Lessor Default. Subject to Section 9.3, Lessor shall be in default in the event any representation or warranty made by Lessor herein shall prove to have been inaccurate in any material respect at the time made, or in the event Lessor breaches or fails to comply in any material respect with any covenant or agreement contained herein.

9.3. Right to Cure. If a Party (the “Defaulting Party”) defaults pursuant to an Event of Default, such Defaulting Party shall not be in default of the terms of this Agreement if (other than in the event of a default described in Sections 9.1(b) and/or 9.1(c) above), (a) in the case of a Monetary Default, the Defaulting Party pays the past due amount within thirty (30) days of receiving a Notice of Default from the other Party (the “Non-Defaulting Party”), and (b) in the case of a Non-Monetary Default, the Event of Default is cured within forty-five (45) days of receiving the Notice of Default; provided, that if the nature of the Non-Monetary Default requires, in the exercise of commercially reasonable diligence, more than forty-five (45) days to cure then the Defaulting Party shall not be in default as long as it commences performance of the cure within forty-five (45) days and thereafter completes such cure with commercially reasonable diligence.

9.4. Remedies.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

(c) Any amounts recovered by Lessor from Lessee in the event of a default shall, to the maximum extent permissible under Applicable Laws, be deemed to be in respect of past or future Rent owing under this Agreement.

ARTICLE X

CAPITAL EXPENDITURES

10.1. Capital Expenditures Generally.

(a) Lessee has provided to Lessor in the CapEx Budget the approximate amounts of Capital Expenditures that Lessee expects will be needed for purposes of funding Footprint Projects in each Lease Year through 2017. On or before October 15 of each calendar year, Lessee shall review and revise the CapEx Budget on a rolling three-year basis (which shall include, if applicable, any year in such three-year period following the end of the then-current Term and assume the renewal of this Agreement pursuant to Section 2.1), taking into account any changed circumstances that (i) make it no longer feasible to incur one or more of the costs reflected on the prevailing CapEx Budget, (ii) make it necessary to amend the nature or amounts reflected for a particular Footprint Project or (iii) dictate that additional Footprint Projects be added (such budget, as so updated and revised, is referred to herein as the “CapEx Budget”). Lessee agrees to revise the CapEx Budget to include any Footprint Projects (x) required by Regulatory Authorities or (y) reasonably necessary to satisfy Lessee’s obligation as a regulated utility to serve its customers or to maintain the safety or reliability of the ERCOT Transmission Assets. Capital Expenditures included in a CapEx Budget will be included based on the date such Capital Expenditures are to be incurred, which differentiates these Capital Expenditures from Incremental CapEx and Lessee CapEx, which are measured under this Agreement based on when the assets developed with such Capital Expenditures are placed in service, and not when they are incurred.

(b) If requested by Lessor, Lessee will also provide an estimate of any Capital Expenditures that Lessee expects for purposes of funding Personal Property related to the ERCOT Transmission Assets. If Lessor and Lessee agree, Lessor will fund such Capital Expenditures pursuant to this Agreement, through a loan or through a separate lease. Amounts Lessor provides pursuant to this Agreement to fund any such Personal Property will be treated in a manner similar to any amounts Lessor provides to fund Footprint Projects for purposes of Section 3.2 and elsewhere herein. Lessee will cause any such Personal Property to be titled in Lessor’s name and will reasonably cooperate with Lessor in order to enable any secured lender of Lessor or any secured lender of an affiliate of Lessor to perfect its security interest in any such Personal Property. In the alternative, Lessor may elect to fund such Capital Expenditures through a TRS or to loan (or cause such TRS to loan) Lessee the cash to acquire any such Personal Property in a transaction in which Lessor or a TRS may retain a security interest in such Personal Property. In such case the Parties shall negotiate in good faith the terms under which Lessor or such TRS shall fund any such Personal Property, including the terms of any lease between Lessee and the TRS or other financing arrangements provided by the Lessor or the TRS.

10.2. Capital Expenditures Funded by Lessor Lessor agrees to fund any Footprint Projects contained in the CapEx Budget (as revised from time to time). Lessor’s obligation to fund Footprint Projects pursuant to this Section 10.2 shall include any costs associated with such Footprint Projects that Lessee is not allowed to recover through its PUCT-approved rates. Any Footprint Projects funded by Lessor under this Section 10.2 shall be deemed to be part of the ERCOT Transmission Assets upon completion.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

10.3. Capital Expenditures Funded by Lessee. Except as set forth in this Section 10.3, Lessee may not fund any Footprint Projects. In the event Lessor fails to fund any Footprint Projects, Lessee may at its sole discretion fund the needed capital expenditures (and Lessee shall be entitled to applicable damages, if any, as a result of funding any such Footprint Projects); provided that, in such circumstance, Lessee may fund Severable Footprint Projects without restriction under this Section 10.3 but may only fund Nonseverable Footprint Projects which are required in order to comply with Applicable Law or which are required by any Regulatory Authority. Any Footprint Projects funded by Lessee under this Section 10.3 shall not be considered part of the ERCOT Transmission Assets for purposes of this Agreement; provided however, that any part of the ERCOT Transmission Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the ERCOT Transmission Assets and reverts to the Lessor upon termination of this Agreement without further payment from Lessor to Lessee under Section 2.3.

10.4. Footprint Project Construction Activities. Lessee will either use its personnel, or either Lessee or Lessor will contract with third parties, to construct Footprint Projects. Lessee shall be responsible for the oversight of such construction activities, regardless of whether the Footprint Project is funded by Lessor or Lessee. Lessee’s construction activities and oversight shall be intended to ensure that such construction is performed in a manner consistent with Good Utility Practice and does not adversely affect the reliability and safety of the ERCOT Transmission Assets or the ERCOT electric grid. In connection therewith, Lessor will reimburse Lessee for all Project Management Costs that Lessee incurs in connection with constructing such Footprint Project, provided that any costs and expenses of Lessee under this Section 10.4 must be included in any CapEx Budget submitted by Lessee under Section 10.1 or approved by Lessor to qualify for reimbursement by Lessor hereunder.

10.5. Ownership of Footprint Projects

(a) Each Footprint Project shall be owned by the Party that funded the capital expenditures used to construct such Footprint Project; provided however, that any part of the ERCOT Transmission Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the ERCOT Transmission Assets and shall revert to the Lessor upon termination of this Agreement without further payment from Lessor to Lessee under Section 2.3.

(b) Upon the expiration or termination of this Agreement, Lessor shall have the right (but not the obligation) to purchase, subject to required regulatory approvals, any Nonseverable Footprint Projects or Severable Footprint Projects owned by Lessee at the greater of (i) net book value plus ten percent (10%) and (ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail to agree on the amount of the purchase price, the purchase price shall be submitted to arbitration in accordance with Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine the amount of the purchase price, based on submissions by each of the Lessee and the Lessor. Lessee shall be entitled to remove any Severable Footprint Projects owned by Lessee upon the expiration or termination of this Agreement in the event such Severable Footprint Projects are not purchased by Lessor, subject to any required regulatory approvals.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

10.6. Asset Acquisitions. Lessee and Lessor will cooperate in good faith to ensure that all ERCOT Transmission Assets are acquired in Lessor’s name or are acquired by Lessee and subsequently transferred to Lessor. In connection therewith, Lessee agrees (a) to transfer to Lessor all previously acquired ERCOT Transmission Assets, (b) that any future-acquired ERCOT Transmission Assets will be deemed automatically transferred to Lessor, (c) to take reasonable actions as are necessary and appropriate to document the transfer of any such ERCOT Transmission Assets to Lessor and, if applicable, to memorialize the security interest in such ERCOT Transmission Assets required to be granted pursuant to the terms of the Debt Agreements, including through the delivery and recordation of mortgages, deeds of trust or UCC financing statements, and (d) to take reasonable steps to record the transfer and such security interest in the records of the applicable county or other applicable locale in which the ERCOT Transmission Assets are located.

10.7. Reimbursements. From time to time, Lessee may enter into interconnect or similar agreements that obligate the counterparty to such agreements to reimburse Lessee for Capital Expenditures in certain circumstances. Such reimbursement obligation may, in some circumstances, be accompanied by additional security such as parent guaranty or a letter of credit. If and to the extent that (a) Lessor funds Capital Expenditures that are used for the construction or development pursuant to any of these interconnect agreements, and (b) Lessee becomes entitled to assert any reimbursement or other rights pursuant to any such interconnect agreements, then, unless Lessor agrees otherwise, Lessee will enforce such reimbursement or other rights and will in turn reimburse Lessor for the amount of related Capital Expenditures that Lessor has funded pursuant hereto. Lessee further agrees to reimburse Lessor for other Capital Expenditures that Lessor has funded pursuant to this Agreement to the extent required by the Policies and Procedures.

ARTICLE XI

REGULATORY COOPERATION

11.1. Jurisdiction. The Parties recognize that (i) the ERCOT Transmission Assets and the operation thereof are subject to the jurisdiction of the PUCT and to certain reliability and safety requirements of ERCOT and TRE, and (ii) Lessee holds CCNs for operation of the ERCOT Transmission Assets. The Parties agree that, as the lessee hereunder, as operator of the ERCOT Transmission Assets and as the holder of the CCNs, Lessee shall be responsible for compliance with all regulatory requirements related to the ERCOT Transmission Assets, including but not limited to, taking all actions reasonably necessary or advisable to comply with such requirements; preparing and filing all necessary notices, reports, applications, and other materials with the PUCT, ERCOT, TRE and NERC; and initiating, prosecuting, defending or participating in any administrative or judicial proceeding reasonably necessary or advisable to operate the ERCOT Transmission Assets in an economical and efficient manner. Lessee shall consult with Lessor prior to initiating any rate proceeding with the PUCT to change the rates Lessee can lawfully charge, provided that, with or without Lessor consent, Lessee shall be authorized to initiate any such rate proceeding. Upon Lessor’s request, Lessee shall file a rate proceeding before the PUCT; provided that, Lessor shall be responsible for reimbursing Lessee for all costs associated with prosecution of such proceeding to the extent that such costs are not recoverable in Lessee’s PUCT-approved rates.

ERCOT TRANSMISSION ASSETS LEASE AGREEMENT

11.2. Cooperation. The Parties agree that during the term of this Agreement they will cooperate to assure compliance with all applicable regulations, orders or lawful requests of any governmental or Regulatory Authorities that relate to the ERCOT Transmission Assets and Lessee’s obligations as the holder of the CCNs and will provide such information to such governmental and Regulatory Authorities as the other Party or such governmental or Regulatory Authorities may reasonably request in connection therewith. Lessor further agrees to use its best efforts to cooperate and promptly respond to any lawful requests from Lessee relating to Lessee’s efforts to comply with all regulatory requirements or to participate in any necessary or advisable legal proceedings, whether judicial or administrative. Each Party shall bear its own costs in complying with this paragraph.

ARTICLE XII
