PERMIAN LEASE AGREEMENT 

 PERMIAN LEASE AGREEMENT 

This PERMIAN LEASE AGREEMENT (this “Agreement”) is entered into effective as of December 31, 2017 (the
“Effective Date”), between Sharyland Distribution & Transmission Services, L.L.C. (together with its permitted transferees, successors and assigns, “Lessor”), and Sharyland Utilities, L.P. (together with
its permitted 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 and Lessee entered into that certain Third Amended and Restated Lease Agreement (Stanton/Brady/Celeste Assets), effective as
of December 31, 2015 (as amended, restated, supplemented or otherwise modified from time to time, the “Amended and Restated Lease”), pursuant to which Lessee leases the Permian Assets from Lessor; 

WHEREAS, the Amended and Restated Lease is scheduled to expire on the Effective Date; and 

WHEREAS, as of the Effective Date, the Amended and Restated Lease will be terminated, and Lessor and Lessee desire to enter into a new lease
agreement on the terms and conditions set forth herein and effective as of the Effective Date covering the Permian Assets and, in the future, Footprint Projects 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 hereby agree as follows: 
 ARTICLE I 

LEASE 
 1.1.
Lease of Permian 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 Permian Lease Assets. Subject to any necessary regulatory approvals and Section 1.1(b), this Agreement is intended by Lessor and Lessee to be a master lease of the Permian Lease Assets,
as they existed as of the Original Lease Date and as they have been or may continue to be altered or expanded thereafter by Footprint Projects in which Lessor has an interest, which may include: 

(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 and poles; 
  

PERMIAN LEASE AGREEMENT 

 (ii) overhead, underground and underwater electrical 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 Permian Assets, and the building housing the foregoing items; 

(iv) all facilities associated with any high-voltage direct current interconnections, including alternating current/direct
current converter stations; 
 (v) electric meters required to operate the Permian Assets; 

(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 Code and the regulations promulgated thereunder, and not otherwise included in Section 1.1(a)(i)-(v) above) owned or leased by Lessor and underlying the Permian
Assets, including related easements, licenses, rights of way and other real property interests; and 
 (vii) all other
assets, facilities, systems or property owned or leased by Lessor that physically comprise part of the Permian Assets and that are (x) 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 (the “FERC Uniform System of Accounts”) and (y) not otherwise included in Section 1.1(a)(i)-(vi) above). 

For the avoidance of doubt, the Permian Assets shall include any components of the Permian Assets that are repaired or replaced pursuant to
Section 6.1. 
 (b) 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 Permian Assets (and Lessee shall not be authorized to use or operate such Footprint Project, alteration, expansion or addition to the Permian 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 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
“Permian Assets” rely on the assumption that this is the case. 
 (c) Notwithstanding anything to the contrary in this
Section 1.1, for so long as Lessor is in compliance with its obligation to fund Capital Expenditures pursuant to Article X, Lessor may notify Lessee of its intention to transfer certain assets that would otherwise constitute
Permian Assets under this Agreement (the “Transferred Assets”) to a TRS. Upon any such notification, the TRS and Lessee shall negotiate in good faith a lease agreement with respect to such Transferred Assets, on terms and conditions
that are comparable to those contained herein, and, upon the execution of such lease, the Transferred Assets shall no longer constitute Permian Assets hereunder. 

  
 2 

 PERMIAN LEASE AGREEMENT 

 1.2. Exclusive Rights. Throughout the Term of this Agreement, Lessee shall
have the exclusive right (a) to operate and use the Permian Lease Assets for the transmission and distribution of electricity in accordance with applicable rules and regulations of all regulatory agencies having regulatory jurisdiction over the
Permian Assets, including the PUCT, as well as applicable rules and regulations of ERCOT, TRE, NERC and other Regulatory Authorities, and (b) to utilize the Permian Lease Assets for other uses (provided that such other uses do not
interfere with the current or future transmission and delivery of electricity, Good Utility Practice or Applicable Laws and do not adversely affect the reliability and safety of the Permian Assets or the ERCOT electric grid). Throughout the Term of
this Agreement, Lessor shall have access to the Permian Assets at all reasonable times for purposes of inspection and for the purposes of evaluating potential improvements, expansions or modernizations of the Permian Assets in accordance with
Article X. Except in the case of emergency, prior to Lessor’s access of the Permian 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 and costs associated with the lease, license, servicing, insuring, maintenance, repair and operation of the Permian Assets and the performance of Lessee’s obligations under this Agreement shall be for the account
of Lessee, unless expressly stated that such expenses or costs are for the account of Lessor or some other Person). 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 Permian Lease 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. 

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, 2020 unless otherwise terminated in a manner consistent herewith (the “Initial 

  
 3 

 PERMIAN LEASE AGREEMENT 

 
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 Lessor with a Comparable Rate of Return on the then-current Rate Base of the Permian Assets. 

2.2. Approvals upon Expiration or Termination.  

(a) Notwithstanding anything to the contrary contained in this Agreement, Lessee shall not surrender, resign, transfer, assign or otherwise
cease to be the operator of the Permian 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 any period of time after the expiration of
the Term or termination of this Agreement but prior to Lessee’s acquisition or receipt of any necessary regulatory approvals with respect to Lessee’s surrender, resignation, transfer, assignment or other cessation of its operation of the
Permian Assets (such period of time being herein referred to as the “Extended Period of Operatorship”), Lessee shall continue to operate the Permian Assets and shall continue to pay all Extended Period Rent and perform all of
Lessee’s other obligations under this Agreement; provided, however, that if regulatory approval is not obtained within twelve (12) months of initiation of the approval process and such delay is (i) 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 (ii) 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
(i) 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 Operating CCNs for the Permian Assets to Lessor or
Lessor’s transferee or designee and (ii) upon receipt of such approvals, transfer or assign, to the extent permitted by Applicable Law, such Operating CCNs to Lessor or Lessor’s transferee or designee. 

(d) The obligations of Lessee and Lessor contained in this Section 2.2 shall survive the expiration of the Term or termination of
this Agreement. 
 2.3. Purchase Option upon Expiration or Termination. Upon the later of (a) the expiration of
the Term or termination of this Agreement and (b) the expiration of the Extended Period of Operatorship (if any), Lessor shall have the option to purchase, or cause such other Person as Lessor may direct to purchase, from Lessee any equipment
or other property, tangible or intangible, including any regulatory assets, owned by Lessee and principally used in connection with and necessary for the operation of the Permian 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.

 PERMIAN 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, or at such
other place or to such other Person as Lessor from time to time may designate in a written notice to Lessee, all Rent contemplated hereby during the Term or any Extended Period of Operatorship 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) Lessee will pay Lessor Base Rent for each Lease Month, payable in arrears forty-five (45) days after the conclusion of the Lease
Month. 
 (b) Except as otherwise provided in Section 3.6, in addition to the Base Rent set forth above, Lessee covenants and
agrees to pay to Lessor, as percentage rent, an annual amount at the Percentage Rent Rate on Gross Revenues during the applicable Lease Year that are in excess of the Annual Percentage Rent Breakpoint for such Lease Year (“Percentage
Rent”). Percentage Rent owed by Lessee under this Agreement shall be calculated quarterly, and, if any Percentage Rent is due, shall be paid not later than the date that is forty-five (45) days after the end of each Lease Quarter as
follows: 
 (i) Percentage Rent will only be payable with respect to a particular Lease Quarter if the aggregate Gross
Revenues for the Lease Year through the end of the applicable Lease Quarter (the “Year-to-Date Revenues”) exceed the Applicable Quarterly Breakpoint. If so, then the Percentage Rent payable with respect to a Lease Quarter will be an
amount equal to: 
 (1) the product of (x) the amount by which Year-to-Date Revenues exceed the Applicable Quarterly
Breakpoint multiplied by (y) the Percentage Rent Rate; minus 
 (2) any Year-to-Date Payments; 

provided that, except as provided in Section 3.1(b)(ii), if the foregoing calculation results in a negative number, Lessee
shall not be entitled to a refund of any Percentage Rent previously paid. 
 (ii) If, at the end of the Lease Year, the
Year-to-Date Payments made by Lessee to Lessor with respect to such Lease Year exceed the annual amount of Percentage Rent payable by Lessee to Lessor for such Lease Year pursuant to the first sentence of Section 3.1(b), then Lessor
shall refund any excess amounts to Lessee by March 31 of the year following the applicable Lease Year. 

  
 5 

 PERMIAN LEASE AGREEMENT 

 (iii) Within forty-five (45) days after the end of each Lease Quarter, or,
if earlier, concurrently with the payment by Lessee of any Percentage Rent owed pursuant to this Section 3.1(b), Lessee shall deliver to Lessor a CFO Certificate, in the form attached as Exhibit A, setting forth Lessee’s
calculation of Gross Revenues as determined in accordance with Exhibit E and the resulting Percentage Rent payable hereunder. The CFO Certificate 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 (the “Effective Date Rent
Supplement”) with respect to the estimated Effective Date Rate Base and Expected Incremental CapEx during 2018. Prior to the beginning of each Lease Year (and, if applicable, at such other times during the Lease Year if the Parties expect
Incremental CapEx and the Parties have not yet entered into a Rent Supplement with respect to such Expected Incremental CapEx), the Parties will negotiate in good faith to supplement, in the form of Schedule 3.2, Rent and other matters
in accordance with this Section 3.2 (each, a “Rent Supplement”) to reflect the amount of Incremental CapEx, if any, that the Parties expect to be placed in service during such Lease Year (“Expected Incremental
CapEx”). The following will apply to the determination of the matters set forth on the Rent Supplement: 
 (i) The
Parties will supplement Base Rent and Percentage Rent in a manner intended to provide a Comparable Rate of Return for Lessor on the Expected Incremental CapEx. Such Comparable Rate of Return may be achieved by a split between Base Rent and
Percentage Rent, in such case 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 the assets developed with such Capital Expenditures are placed in service (notwithstanding that Capital
Expenditures that are included in CapEx Budgets pursuant to Article X are for such purposes measured based on the date the related Capital Expenditures are incurred). 

(iii) Notwithstanding anything to the contrary contained in this Agreement, such supplement shall be determined solely to
provide a Comparable Rate of Return on such Expected 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 Rent payable with respect to, the Permian Assets as in place prior to the additions resulting from such Expected Incremental CapEx. 

  
 6 

 PERMIAN LEASE AGREEMENT 

 (b) 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 Permian Assets or the Stanton Transmission Loop Assets and are classified as Lessee CapEx. The following will apply to the determination of Revenues Attributable to Lessee CapEx: 

(i) Revenues Attributable to Lessee CapEx shall be targeted to equal that portion of the amounts collected by Lessee with
respect to the Permian Assets or Stanton Transmission Loop Assets, as applicable, 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). For the avoidance of doubt, Revenues Attributable to Lessee CapEx shall not include any ERCOT Transmission Revenues.

 (ii) 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. Further, the Parties understand that there may be Capital Expenditures that relate to both
(A) the Permian Assets and/or the Stanton Transmission Loop Assets and (B) other assets 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 constitutes Lessee CapEx hereunder. 
 (iii) Notwithstanding anything to the contrary
contained in this Agreement, 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 the Lessee CapEx as in place prior to the additions resulting from such Lessee CapEx. 

(iv) 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 and the Parties have not yet entered into a Rent Supplement with respect to such Lessee CapEx, Lessee may request, no more frequently than annually, that the Parties
determine the Revenues Attributable to Lessee CapEx that 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). 

(c) The Parties will memorialize the results of all Rent negotiations pursuant to Section 3.2(a) and Lessee CapEx supplement
negotiations pursuant to Section 3.2(b) by executing and delivering a Rent Supplement, which will set forth, in each case to the extent applicable, (i) the amount and projected depreciation rate of the Expected Incremental CapEx and
Lessee CapEx; (ii) the estimated weighted average placed-in-service date of the Expected Incremental CapEx and Lessee CapEx; (iii) the projected effective date of the Regulatory Order(s) related to the Expected Incremental CapEx and Lessee
CapEx; (iv) the new Base Rent; (v) a new Percentage Rent Schedule; (vi) new Revenues Attributable to Lessee CapEx; (vii) a new TCOS Allocation and (viii) the effective date of the new Rent Supplement. Upon the execution and

  
 7 

 PERMIAN LEASE AGREEMENT 

 
delivery of any such Rent Supplement, this Agreement will be deemed amended thereby. 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, before the assets funded by the related Incremental CapEx or Lessee CapEx are placed in service. Further, the Percentage Rent Rates 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. 

(d) Either Party may request a revision to the TCOS Allocation utilized to calculate Allocated ERCOT Transmission Revenues pursuant to
Exhibit E based on the most recent available monthly balance sheet in connection with any Rent Supplement executed and delivered by the Parties under Section 3.2(c) or, if earlier, no more frequently than once every sixty
(60) days. 
 (e) If Lessee receives or expects to receive any fees, charges or Other Revenue (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 the
then-effective Rent Supplement related to 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 Allocated Other
Revenue hereunder or under such other similar lease. 
 (f) 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 within sixty (60) days of a request therefor by either Party. 

3.3. Validation. 

(a) Following the conclusion of each Lease Year (and, if applicable, at such other times during a Lease Year as a Party may request), the
Parties will: 
 (i) review and determine whether there is a difference in: 

(1) with respect to the Effective Date Rent Supplement, the actual Effective Date Rate Base compared to the Effective Date
Rate Base contemplated by the Effective Date Rent Supplement; or 
 (2) the actual (A) amount of Incremental CapEx or
Lessee CapEx, as applicable, placed in service during such Lease Year, (B) weighted average placed-in-service date of and/or effective date of the Regulatory Order(s) related to such Incremental CapEx or Lessee CapEx, as applicable and/or
(C) depreciation rate, in each case as compared to what was contemplated by the Rent Supplement in effect as of the end of such Lease Year; and 

  
 8 

 PERMIAN LEASE AGREEMENT 

 (ii) if there has been such a difference, execute and deliver a revised Rent
Supplement, which will set forth: 
 (1) a revised Base Rent, Percentage Rent Schedule and TCOS Allocation, reflecting what
they would have been, at the time of the Rent Supplement, based on the actual (A) Effective Date Rate Base (with respect to the Effective Date Rent Supplement), (B) amount of Incremental CapEx or Lessee CapEx, as applicable,
(C) weighted average placed-in-service date of or effective date of the Regulatory Order(s) related to such Incremental CapEx or Lessee CapEx, as applicable and/or (D) depreciation rate, but keeping fixed all other relevant assumptions and
inputs, including the Comparable Rate of Return; and 
 (2) the amount of any lump sum payment that one Party must make to
the other Party as a result of excess or deficient Rent that Lessee paid, as applicable (which payment must be made within thirty (30) days of the execution and delivery of such revised Rent Supplement and, if applicable, shall be treated as
Rent by the Parties). 
 Upon the execution and delivery of any revised Rent Supplement pursuant to Section 3.3(a)(ii), this Agreement will be
deemed amended thereby. The process described in this Section 3.3(a) is referred to as a “Rent Validation.” 

(b) 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. 

(c) For the avoidance of doubt, notwithstanding anything to the contrary contained herein, following any expiration or termination of this
Agreement pursuant to Article II, the Parties will conduct a Rent Validation in accordance with Section 3.3(a) with respect to the final Lease Year (or applicable portion thereof) ending immediately prior to the effective
date of such expiration or termination and determine whether one Party should make a lump sum payment to the other Party as a result of excess or deficient Rent paid by Lessee. If any amount is determined to be due based upon such Rent Validation,
the payment of such amount must be made within thirty (30) days of the finalization of such Rent Validation and, if applicable, shall be treated as Rent by the Parties. 

(d) In connection with the foregoing provisions of this Section 3.3, Lessor and Lessee shall use good faith efforts to agree to a
Rent Validation within sixty (60) days of the conclusion of the applicable Lease Year or a request therefor by either Party. 
 3.4.
Confirmation of Percentage Rent. 
 (a) In the event that Lessee determines that the Percentage Rent paid with
respect to any Lease Year (after giving effect to any refund that has or will be paid pursuant to Section 3.1(b)(ii)) 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 

  
 9 

 PERMIAN LEASE AGREEMENT 

 
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 3.4(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. 
 (b) Lessee shall record Gross Revenues in order to
provide an audit trail and shall utilize, or cause to be utilized, an accounting system for the Permian Assets in accordance with the FERC Uniform System of Accounts that will accurately record all data necessary to compute Percentage Rent. 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 3.4(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 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 3.4(c), if any Lessor’s Audit discloses a deficiency in the payment of
Percentage Rent which, as finally agreed or determined, exceeds three percent (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
(2nd) 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 3.4 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 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. 

3.5. Additional Obligations. 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 the expenses and costs 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 costs or performs such obligations on behalf of Lessee (collectively, “Additional Rent”). 

  
 10 

 PERMIAN LEASE AGREEMENT 

 3.6. Certain Exceptions. Notwithstanding anything to the contrary contained
herein, at any time that Rent for all of the Permian Lease Assets is comprised solely of Base Rent (i.e. the Percentage Rent Rate for all of the assets covered by the then-effective Rent Supplement is zero (0%)), then the provisions of
Sections 3.1(b), 3.2(d) and 3.4 (and the related definitions, including Exhibit E) shall be null and void, and the Parties shall have no obligation to comply with the provisions thereof; provided that, to
the extent any such provision would otherwise be applicable with respect to any Lease Year (or applicable portion thereof) during which Percentage Rent was payable, then the relevant provision(s) shall continue to apply to any such period. 

3.7. No Set Off. Any amount owed by Lessee pursuant to this Agreement 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. 
 3.8. Late Payment Penalty. Except as otherwise provided in Section 9.1(b),
if Lessee fails to make any payment to Lessor of any amount owed hereunder 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. 

3.9. 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 a letter of credit, a prepayment, or a guaranty. 

3.10. Survival. The obligations of Lessee and Lessor contained in this Article III with respect to the
calculation, validation and payment, including late payment, of Rent applicable to periods prior to the end of the Term or during any Extended Period of Operatorship shall survive the expiration or earlier termination of this Agreement. 

ARTICLE IV 

LESSEE’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

4.1. Maintenance, Operation and Repair of the Permian 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 the construction of Footprint Projects, which shall be subject to Article X) to the Permian 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 Permian 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 

  
 11 

 PERMIAN LEASE AGREEMENT 

 
consistent with Good Utility Practice and in accordance with manufacturers’ warranty requirements (during any applicable warranty period) and Lessee’s established operating procedures
and maintenance, rebuild and repair programs so as to keep the Permian 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
Permian Assets in a reliable and safe manner in compliance with Applicable Laws. Lessee will not operate the Permian 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 Permian Assets by Lessor show that the Permian 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 Permian Assets can be modified or replaced to comply with industry standards, Good Utility Practice and any Applicable Law and (ii) complete any and all such modifications and/or replacements consistent with all applicable reliability and
safety standards established by Good Utility Practice and Applicable Law. 
 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 (or collect from its customers, as applicable) 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 (including, if applicable, any Extended Period of Operatorship) be imposed on, or arise in
connection with, the ownership, lease, repair, maintenance and/or operation of the Permian Assets (including all Footprint Projects) (excluding any Lessor Taxes, “Lessee Taxes”); provided that such payment shall not be
required with respect to any such tax, assessment, charge or fee to the extent the validity or amount thereof is being contested in good faith in accordance with Applicable Law (and in consultation with Lessor) by appropriate proceedings and Lessee
sets aside on its books adequate reserves or other appropriate provisions with respect thereto in accordance with GAAP; provided further that Lessee shall not be obligated by reason of this Agreement to pay any income, franchise or similar
taxes imposed upon Lessor, any consolidated, combined unitary or similar group that includes Lessor or any direct or indirect owner of an equity interest in Lessor, or any transfer, recordation, sales, use or similar taxes which arise in connection
with Lessor’s acquisition of Footprint Projects, or the construction of Footprint Projects funded by Lessor (“Lessor Taxes”). For the avoidance of doubt, Lessee Taxes shall not include any amounts related to periods prior to
the Original Lease Date. The Parties understand that Lessee collects certain Lessee Taxes from Lessee’s customers and remits such payments to the appropriate Regulatory Authority, and that nothing in this Section 4.3 is intended to
impose liability on Lessee (instead of such customer) for the related tax liability beyond that imposed by Applicable Law with respect to such collection obligations. 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 Permian Assets or any component thereof or interest therein. Lessee shall assume full responsibility for preparing and

  
 12 

 PERMIAN LEASE AGREEMENT 

 
furnishing to Lessor for execution all filings with any Regulatory Authority of or in the state and/or locality in which the Permian Assets are located in respect of any and all Lessee 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 Applicable 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 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 or administrative proceedings the
validity or applicability to the Permian Assets of any Applicable Law made or issued by any federal, state, county, local or other Regulatory Authority. Any such contest or proceeding shall be controlled and directed by Lessee. Lessee shall provide
Lessor with written notice of the commencement of any such legal or administrative proceedings that relate to or are a Lessor Material Matter. Thereafter, if requested by Lessor, Lessee will update Lessor, at reasonable intervals, of the progress of
any such proceedings that relate to or are a Lessor Material Matter. 
 4.5. Liens. Lessee shall keep the Permian
Assets free and clear of all Liens other than Permitted Liens. If Lessee fails to promptly remove any Lien (other than Permitted Liens) that may be imposed on the Permian Assets, 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 Permian Assets and conduct all of its other activities in respect thereof in compliance in
all material respects with any Environmental Laws and other 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 that is a Lessor Material Matter. 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, in the case of any Lessor
Material Matter) 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 with respect to any Lessor Material Matter. 
 (b) Without limiting the generality of the foregoing,
Lessee shall not (i) place or locate any underground tanks on the property underlying the Permian Assets (except in accordance with Good Utility Practice and in a manner that does not prevent Lessee from complying with its obligations pursuant
to Section 6.2); (ii) generate, manufacture, transport, produce, use, treat, store, release, dispose of or otherwise deposit Hazardous Materials in or on the Permian Assets, the property underlying the Permian Assets or any portion
thereof other than 

  
 13 

 PERMIAN LEASE AGREEMENT 

 
as permitted by Environmental Laws that govern the same or are applicable thereto; (iii) permit any other substances, materials or conditions in, on or emanating from the Permian Assets, the
property underlying the Permian 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 Permian 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 expense, conduct inspections of all components of the Permian Assets to ensure compliance with Applicable Laws and with this
Section 4.6, and, if requested by Lessor or as otherwise provided in Section 4.6(a), 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 from and against any and all Claims suffered or incurred by Lessee and arising from Lessor’s testing in accordance with Section 12.2. 

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 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 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 C 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, Lessee shall cause its subsidiaries not to
incur Indebtedness in an aggregate principal amount greater than 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. 

  
 14 

 PERMIAN LEASE AGREEMENT 

 4.8. Records. In addition to the records referred to in
Section 3.4(b), Lessee shall maintain proper books of record and account in conformity with GAAP and all applicable Regulatory Authorities 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 Permian Assets by Applicable Laws or by 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 the 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, at its expense, vacate and surrender possession of the Permian Assets and all components
thereof (other than in respect of Footprint Projects funded by Lessee as described in Section 10.3, and which are not purchased by Lessor) to Lessor, or to such other Person as Lessor may direct. At the time of such surrender, the
Permian Assets shall be free and clear of Liens and other rights of third parties (other than Permitted Liens set forth in clauses (i), (v), (vi) or (vii) of the definition thereof), and shall be in the same condition as on the Original
Operations Date, ordinary wear and tear and subsequent Footprint Projects excepted. At the time of such surrender, Lessee shall, at its expense, deliver or cause to be delivered to Lessor, or to such other Person 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 Permian Assets which are necessary to determine the condition of
the Permian Assets or for the continued maintenance, repair or general operation of the Permian Assets and are in Lessee’s possession or control at such time. In addition, Lessee shall cooperate with Lessor to identify any contractual
arrangements to which Lessee is a party that relate to the Permian Assets, including any interconnection agreements, fiber sharing agreements or similar arrangements, and, at Lessor’s option and expense, shall use commercially reasonable
efforts to transfer, to the extent permitted by Applicable Law, in whole or in part applicable to such Permian Assets, such agreements to Lessor or its designee. In connection with the surrender of the Permian 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 (i) after notice of termination and prior to the termination of the Agreement or (ii) after Lessor has
notified Lessee that Lessor is considering a sale, lease or financing involving the Permian Assets, with reasonable notice, Lessee will cooperate in all reasonable respects with the efforts of Lessor to sell, lease or finance the Permian Assets (or
any component thereof) or any interest therein, including permitting prospective purchasers, lessees or financing sources to fully inspect the Permian 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 Permian Assets or cause Lessee to incur any additional expenses other than as specifically provided herein; provided further that
such cooperation shall not include requiring Lessee to terminate this Agreement, surrender any rights under this Agreement or otherwise modify this Agreement in any manner. 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. 

  
 15 

 PERMIAN LEASE AGREEMENT 

 (b) Upon expiration or termination of this Agreement, Lessee shall continue to lease and operate
the Permian 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 this Agreement in all respects, as if the Agreement had not expired or
been terminated, and will pay Extended Period Rent as and when due. 
 4.11. Lessee’s Authority; Enforceability.
Lessee hereby represents and warrants as follows, as of the Effective Date: 
 (a) 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. 
 (b) 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 Permian Assets, Lessee shall promptly deliver notice thereof to Lessor. 

4.13. Financing. 

(a) Lessee acknowledges that Lessor has advised Lessee that Lessor has obtained financing secured by, among other things, the Permian 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

 (e) Lessee may
not lease, or agree or otherwise commit to lease, any transmission or distribution facilities other than pursuant to a Lease. Further, Lessee shall not permit Persons other than Hunt Family Members to acquire any interest in Lessee, directly or
indirectly, in a manner that would result in a Change of Control of Lessee. 
 (f) The Parties agree to amend, alter or supplement this
Section 4.13, Section 6.2 or Exhibit D hereto from time to time, including through the delivery of a representation letter from Lessee or other form to which the Parties may agree, to give effect to the
obligations under Lessor’s then-current Debt Agreements, including the credit arrangements of any successor to Lessor’s interest in this Agreement. Provided that the obligations or restrictions on Lessee are not materially increased from
those provided for by Lessor’s then-current credit arrangements, such an amendment to this Agreement shall become automatically effective upon the delivery by Lessor to Lessee of a revised version of Section 4.13 and copies of the
pertinent portions of the applicable Debt Agreements referenced therein.

(a) Lessor has all requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder. 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. 

(b) This Agreement constitutes the legally valid and binding obligation of Lessor, enforceable against Lessor in accordance with its terms,

(a) Lessor hereby represents and warrants, as of the Effective Date, that: 

(i) Lessor has good and valid title to, or valid leasehold and easement interests in, or other valid rights to use and occupy
the Permian Assets; there are no unrecorded Liens (except for Permitted Liens or as disclosed to Lessee in writing or as arise by operation of Applicable Law) arising as a result of any acts or omissions to act of Lessor by, through or under Lessor
covering Lessor’s right, title or interest in the Permian Assets other than any such of the foregoing that does not materially impair Lessee’s use of the Permian Assets; and, to Lessor’s knowledge, there exist no rights or interests
of any third party relating to the Permian Assets that are not contemplated herein; and 
 (ii) 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, there are no Liens encumbering all or any portion of the Permian Assets; 

provided that Lessor’s representations and warranties in this Section 5.2(a) shall not be deemed to relate to any inaccuracy of such
representations and warranties arising as a result of any acts or omissions to act of Lessee, its personnel or contractors in carrying out Lessee’s obligations as the operator and lessee of the Permian Assets whether under this Agreement or any
other similar agreement between Lessee or its affiliates on the one hand and Lessor or its affiliates on the other. 
 (b) Lessor shall

 19 

 PERMIAN LEASE AGREEMENT 

 
rights under this Agreement. Notwithstanding the foregoing, Lessor and its affiliates shall have the right to incur Permitted Liens encumbering the Permian Assets or any component thereof solely
for the benefit of Lessor in connection with any existing or future financing or refinancing pursuant to which the Permian Assets (or any component thereof) is pledged as collateral and Lessee agrees to enter into such acknowledgments and agreements
in respect thereof with the lenders, or a trustee or agent for the lenders, as Lessor may reasonably request. 
 5.3. Condition
of Assets. Lessor hereby represents and warrants, as of the Effective Date, that Lessor has not taken any action or failed to take any action that would cause the Permian Assets not to be in good operating condition and repair, ordinary wear
and tear excepted, or adequate for the uses to which it is being put. 
 5.4. Requirements of Governmental Agencies.
Lessor shall, at Lessee’s cost and expense, assist and fully cooperate with Lessee in complying with or obtaining any material land use permits and approvals, building permits, environmental impact reviews or any other approvals reasonably

RELATING THERETO, AND (B) FURTHER DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, OF 

  
 20 

 PERMIAN LEASE AGREEMENT 

 
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS OF ANY PORTION OF THE PERMIAN ASSETS, IT BEING EXPRESSLY UNDERSTOOD AND AGREED BY THE PARTIES
THAT THE PERMIAN ASSETS ARE BEING LEASED “AS IS, WHERE IS,” WITH ALL FAULTS AND DEFECTS, AND THAT LESSEE HAS MADE OR CAUSED TO BE MADE SUCH INSPECTIONS AS LESSEE DEEMS APPROPRIATE. 

ARTICLE VI 
 LOSS AND
DAMAGE; INSURANCE 
 6.1. Loss and Damage to the Permian Assets. 

(a) In the event of any damage or loss to any component of the Permian 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). Notwithstanding anything to the contrary contained in this Agreement, any such repaired or replaced
component will immediately become part of the Permian 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. In such circumstance, unless otherwise agreed by the Parties, (i) if the damage or loss is covered by insurance, Lessee 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 Lessee. If the sum of such deductible and insurance proceeds exceeds the cost of such Repair, then Lessee will retain such excess.

 (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 Lessor. If such repair or replacement
constitutes a Footprint Project that is not included in a CapEx Budget, then the provisions of Article X shall apply, provided that (x) if the Lessor-funded Capital Expenditures for such Footprint Project are expected to
exceed $15 million (after the application of any insurance proceeds, if applicable), Lessee shall revise the CapEx Budget in accordance with Section 10.1(a) to include such Footprint Project and (y) if the Lessor-funded Capital
Expenditures for such Footprint Project are not expected to exceed $15 million (after the application of any insurance proceeds, if applicable), the then-current CapEx Budget shall be deemed to include such Footprint Project. 

  
 21 

 PERMIAN LEASE AGREEMENT 

 (d) Lessee shall be solely responsible for all costs of repairing or replacing any damaged
property and equipment that is not part of the Permian Assets and is 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 Permian 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 D. 
 (a) Lessee shall procure at its own expense and maintain in full force and effect at all times throughout the Term
(including, if applicable, any Extended Period of Operatorship) 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.

 (b) Lessor may at any time amend the requirements and approved insurance companies described in this Section 6.2 or
Exhibit D 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 and
Exhibit D. 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 Permian 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 D. 

  
 22 

 PERMIAN LEASE AGREEMENT 

 (e) In the event Lessee fails to take out or maintain the full insurance coverage required by
this Section 6.2 and Exhibit D, 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 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 D 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 any action taken, or not taken, by Lessor to verify the existence or adequacy of the
insurance coverage maintained by Lessee affect the obligations of Lessee pursuant to this Section 6.2), 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.
Financing Arrangements. 
 (a) Lessee understands that Lessor, or an affiliate thereof, has raised equity and/or
debt capital that may be secured by the Permian 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. 
 (b) Accordingly, Lessee
agrees to provide Lessor in a timely manner: 
 (i) audited year-end financial statements and quarterly unaudited financial
statements for the first three quarters of each year; and 
 (ii) 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 to Lessee but that also allows Lessor sufficient time to comply with its reporting obligations. 

(c) Lessee agrees that the unaudited interim financial statements provided pursuant to this Section 7.1 will be SAS 100
reviewed, and Lessee agrees to use commercially reasonable efforts to cause its auditors to consent to the inclusion of their opinion regarding Lessee’s 

  
 23 

 PERMIAN LEASE AGREEMENT 

 
financial statements in filings to be made by Lessor or an affiliate of Lessor with the SEC (collectively, the “SEC Reporting Requirements”). 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. In addition to including Lessee’s financial statements in the SEC filings of Lessor or an
affiliate thereof, Lessor shall have the right to share any such financial statements with any party entitled to review such financial statements pursuant to the terms of any Debt Agreement. 

(d) Lessee represents, warrants and covenants that (i) the financial statements provided pursuant to this Section 7.1 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 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 of Lessor. 

(e) 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, at Lessor’s cost, to provide one or more comfort letters (or its equivalent) to such underwriters, if requested by Lessor. 

(f) 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. 
 (g) Lessee shall, at the earliest practicable time, 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 cooperate with Lessor when Lessor or an affiliate provides estimates to analysts 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. 

(b) To the extent that either Party requires information from the other Party in order to (i) prepare its financial statements,
(ii) obtain audits of those financial statements and, if required, of its internal control over financial reporting, (iii) respond to comments of the SEC on such financial statements or statements related to internal control over financial
reporting or disclosure controls and procedures, or (iv) ensure the efficacy of its internal controls or disclosure controls and procedures, the Parties agree to reasonably cooperate in order to ensure that each Party is able to meet its
obligations in respect thereof. 

  
 24 

 PERMIAN LEASE AGREEMENT 

 (c) Lessee agrees to promptly notify Lessor of or provide to Lessor, as applicable, (i) any
material communication, written or otherwise, submitted to Lessee by its auditors, including an audit response letter, accountant’s management letter or other written report submitted to Lessee by its accountants or any Regulatory Authority 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 Permian Assets and (iii) any notices of violations of
Applicable Law with respect to the Permian Assets, in each case taking into account InfraREIT’s or any of Lessor’s other affiliates’ reporting obligations with the SEC. 

(d) Lessor agrees to inform Lessee of the time periods in which each of the items identified in this Section 7.2 will be required
by providing written notice thereof to Lessee. Lessee shall, at the earliest practicable time, advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and reasonably cooperate with Lessor to
remedy the effects of such non-compliance. 
 (e) If Lessor identifies additional matters with respect to which Lessee’s 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 Lessor or any such affiliate are listed for or admitted
to trading 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 Permian Assets, as applicable. 
 ARTICLE VIII 

ASSIGNMENT 
 8.1.
Assignment by Lessee. This Agreement shall not be assignable by Lessee, nor shall the Permian Assets or any part thereof be subleased by Lessee (except in a manner consistent with Section 1.2(b)), except with the prior
written consent of Lessor and the prior approval of any Regulatory Authority whose approval is required for the effectiveness of such assignment or sublease. For purposes of this Section 8.1, 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 (a) by operation of Applicable Law and/or (b) 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 that, in the case of clause (b), any such transaction or transactions will only constitute an assignment hereunder to the extent they result (whether in one or a series of transactions) in a Change of
Control. 

  
 25 

 PERMIAN LEASE AGREEMENT 

 8.2. Assignment by Lessor. This Agreement shall not be assignable by Lessor
except with the prior written consent of Lessee and the prior approval of any Regulatory Authority whose approval is required for the effectiveness of such assignment. 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 Lessor may reasonably request and (b) to
assign its interest in this Agreement to a successor owner of the Permian Assets. Notwithstanding anything to the contrary contained herein, except as required by the PUCT or other Regulatory Authorities or as otherwise agreed by Lessee,
Lessee’s rights under this Agreement (including Lessee’s rights to operate the Permian Assets) will survive any sale or transfer of the Permian Assets by Lessor. 

ARTICLE IX 
 DEFAULT

 9.1. Lessee Default. 

(a) Subject to Section 9.3, Lessee shall be in default in the event of any of the following: 

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

(ii) Lessee (A) is generally not paying, or admits in writing its inability to pay, its debts as they become due,
(B) 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, (C) makes an assignment for the benefit of its creditors, (D) 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, (E) is adjudicated as insolvent or to be liquidated, or (F) takes any action for the purpose of any of the foregoing; 

(iii) A court or a Regulatory Authority of competent jurisdiction enters an order appointing, without consent by Lessee, a
custodian, receiver, trustee or other officer with similar powers with respect to it or with respect to any substantial part of its property, or constituting an order for relief or approving a petition for relief or reorganization or any other
petition in bankruptcy or for liquidation or to take advantage of any bankruptcy or insolvency law of any jurisdiction, or ordering the dissolution, winding-up or liquidation of Lessee or any such petition shall be filed against Lessee and such
petition shall not be dismissed within ninety (90) days; 

  
 26 

 PERMIAN LEASE AGREEMENT 

 (iv) Any representation or warranty made by Lessee herein shall prove to have
been inaccurate in any material respect at the time made (unless any representation or warranty is already qualified by materiality or a similar qualification, in which case such representation or warranty shall be accurate in all respects); 

(v) 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 sixty (60) days after entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; or 

(vi) Lessee shall have breached or failed to comply in any material respect with any other covenant or agreement contained
herein (unless any covenant or agreement is already qualified by materiality or a similar qualification, in which case such covenant or agreement shall have been complied with in all respects). 

(b) Notwithstanding Section 9.1(a)(i), Lessee’s failure to pay Rent when due shall not constitute an Event of Default if
(i) such failure is due to unforeseeable circumstances arising from a physical event beyond the control of 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 Applicable 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 (unless any
representation, warranty, covenant or agreement is already qualified by materiality or a similar qualification, in which case (a) such representation or warranty shall be accurate in all respects and (b) such covenant or agreement shall
have been complied with in all respects). 
 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(a)(i), 9.1(a)(ii) and/or
9.1(a)(iii) above, none of which will be subject to a notice and cure period as provided below), (a) in the case of a Monetary Default (other than a Rent payment default pursuant to Section 9.1(a)(i), which shall not be
subject to a notice and cure period except as set forth in Section 9.1(b)), 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 of receiving the Notice of
Default and thereafter completes such cure with commercially reasonable diligence within ninety (90) days of receiving such Notice of Default. 

  
 27 

 PERMIAN LEASE AGREEMENT 

 9.4. Remedies. 

(a) Should an Event of Default remain uncured by the Defaulting Party, the Non-Defaulting Party shall have and shall be entitled to exercise
the remedies provided in this Section 9.4 and any and all other remedies available to it at law or in equity, all of which remedies shall be cumulative; provided that the exercise of any remedies hereunder shall be subject to PUCT
and other required regulatory approvals to the extent applicable and the provisions of Section 2.2. 
 (b) In no way limiting
the provisions of Section 9.4(a), in the case of an Event of Default of Lessee, Lessor shall have the right to (i) terminate this Agreement upon notice to Lessee, and recover from Lessee all damages to which Lessor is entitled under
Applicable Laws, (ii) terminate Lessee’s right to use and operate the Permian Assets (other than leasehold improvements pursuant to Section 10.3) while keeping this Agreement in effect, and recover from Lessee all damages to
which Lessor is entitled under Applicable Laws, and (iii) take reasonable action to cure Lessee’s default at Lessee’s expense; provided that, in the event of a violation of Applicable Laws by Lessee, an emergency or government
or regulatory action in respect of which Lessor, in its reasonable discretion, determines immediate action is necessary, Lessor shall have the right to step in and take such action on behalf of Lessee at Lessee’s cost and expense immediately
upon giving notice to Lessee, notwithstanding any applicable cure period. 
 (c) Any amounts recovered by Lessor from Lessee in the case of
an Event of 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 2020. 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 new Footprint Projects (A) required by Regulatory Authorities or (B) reasonably necessary to
satisfy Lessee’s obligation as a regulated utility to serve its customers or to maintain the safety or reliability of the Permian Assets and the Stanton Transmission Loop Assets. Capital Expenditures included in a CapEx Budget will be included

  
 28 

 PERMIAN LEASE AGREEMENT 

 
based on the date such Capital Expenditures are to be incurred (notwithstanding that Incremental CapEx and Lessee CapEx are otherwise 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 Permian Assets and the Stanton Transmission Loop 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 (i.e., amounts funded to be subject to Comparable Rate of Return). 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 Lessor or the TRS. 

10.2. Capital Expenditures Funded by Lessor. Subject to Section 1.1(b), Lessor agrees to fund during the Term
(including, if applicable, any Extended Period of Operatorship) any Footprint Projects contained in the CapEx Budget (as it may be 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 pursuant to this Section 10.2 shall
be deemed to be part of the Permian Assets upon completion. 
 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 that are required in order to comply with Applicable Law or that are required by any Regulatory Authority. Subject to Section 10.5, any Footprint Projects funded by Lessee under this Section
10.3 shall not be considered part of the Permian Assets or the Stanton Transmission Loop Assets for purposes of this Agreement; provided, however, that any part of the Permian Assets and the Stanton Transmission Loop Assets
that is built with CIAC funds shall be considered a leasehold improvement that is part of the Permian Assets and reverts to Lessor upon the expiration or termination of this Agreement without further payment from Lessor to Lessee under

 PERMIAN LEASE AGREEMENT 

 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 Applicable Law and does not adversely affect the reliability and
safety of the Permian Assets, the Stanton Transmission Loop 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 a 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 Permian Assets or the Stanton Transmission Loop Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the Permian Assets and shall revert to Lessor upon
the expiration or 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, or cause such other Person as Lessor may direct 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. 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. 

10.6. Asset Acquisitions. Lessee and Lessor will cooperate in good faith to ensure that all Permian Assets (including
Footprint Projects relating to the Stanton Transmission Loop Assets) are acquired in Lessor’s name or are acquired by Lessee and subsequently transferred to Lessor, subject to any necessary regulatory approvals. In connection therewith, Lessee
agrees (a) to transfer to Lessor all previously acquired Permian Assets (including Footprint Projects relating to the Stanton Transmission Loop Assets), (b) that any future-acquired Permian 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 Permian Assets (including Footprint Projects relating to the Stanton Transmission Loop Assets) to Lessor and, if applicable, to
memorialize the security interest in such Permian Assets (including Footprint Projects relating to the Stanton Transmission Loop 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 Permian
Assets (including Footprint Projects relating to the Stanton Transmission Loop Assets) are located.

 PERMIAN LEASE AGREEMENT 

 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 a
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 promptly 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.

they will cooperate to assure compliance with all Applicable Laws or other lawful requests of any Regulatory Authorities that relate to the Permian Assets and the Parties’ obligations under the Permian CCNs and will provide such information to
such Regulatory Authorities as the other Party or such 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. Except as otherwise provided in Section 11.1, each Party shall

awarded for Lessee’s leasehold interest under this Agreement or which is awarded for any property owned by Lessee (including any Footprint Projects funded by Lessee). Lessor shall have the right, in its sole discretion, to challenge any
condemnation or taking of the Permian Assets by proper proceedings, and Lessee shall not institute any such challenge without the prior written consent of Lessor. 

13.3. Confidentiality.  

(a) The Parties each acknowledge and agree that, in connection with this Agreement, a Party and its employees or agents may, directly or
indirectly, receive or be provided with certain information relating to the business and operations of the other Party and the other Party’s affiliates, including information relating to the technology, clients, customers, suppliers, vendors,
employees, consultants, projects, financial information and status, methodologies, know-how, processes, practices, approaches, projections, forecasts, formats, systems, data gathering methods and/or strategies, assets, collateral and reports of the
other Party and the other Party’s affiliates (“Confidential Information”); provided, however, that Confidential Information shall not include information which has previously become publicly available through the
actions of a Person not resulting from the violation of this Section 13.3. Each Party acknowledges that the other Party considers all such information valuable, confidential and proprietary. Therefore, each Party (the “Receiving
Party”) expressly agrees, except as required by the PUCT or other Regulatory Authorities to be disclosed, or as otherwise required in accordance with applicable securities laws or tax laws or the rules of any applicable securities exchange
on which securities of the Receiving Party (or an affiliate thereof) are traded, that: 
 (i) the Receiving Party, and its
employees and agents, will not, without the express, written permission of the other Party (the “Disclosing Party”), use or disclose any Confidential Information of the Disclosing Party or its affiliates other than for the purpose
of performing its duties and obligations under this Agreement, and any use or disclosure of Confidential Information shall be limited to the specific purposes for which the permission was given or for which the use or disclosure is necessary to
perform duties and obligations under this Agreement; 
 (ii) the Receiving Party will take all steps reasonably necessary to
protect the Confidential Information of the Disclosing Party and its affiliates, including, at a minimum, any such steps that the Receiving Party would take to protect its own Confidential Information; provided, however, that in no
event will the Receiving Party exercise less than reasonable care to protect the Confidential Information; 
 (iii) the
Receiving Party agrees to advise the Disclosing Party in writing of any misappropriation or misuse by any person of such Confidential Information of which the Receiving Party may become aware; and 

  
 34 

 PERMIAN LEASE AGREEMENT 

 (iv) the Receiving Party agrees to return the Confidential Information of the
Disclosing Party and its affiliates to the Disclosing Party at the earlier of the Disclosing Party’s request for return of the Confidential Information or the expiration or termination of this Agreement. At the option of the Disclosing Party,
the Receiving Party may instead destroy the Confidential Information, with the Receiving Party providing written certification of such destruction. The Receiving Party will not be obligated to return any of its own internally prepared documents,
notes, copies or other associated materials containing any Confidential Information. However, the Receiving Party must, at the Disclosing Party’s request, collect and destroy such internally prepared documents, with the Receiving Party
providing written certification of such destruction. 
 (b) Notwithstanding Section 13.3(a), the Receiving Party may disclose
Confidential Information to any auditor or to the Receiving Party’s equity investors, lenders, attorneys, accountants and other personal advisors; any prospective purchaser of the Permian Assets or a direct or indirect owner thereof; or
pursuant to lawful process, subpoena or court order; provided that the Receiving Party, in making such disclosure, advises the Person receiving the information of the confidentiality of the information and obtains the agreement of said Person
not to disclose the information. 
 (c) Lessee acknowledges that (i) Lessor is indirectly owned, in part, by InfraREIT,
(ii) InfraREIT is a publicly-traded company and (iii) as a result, information regarding Lessor and this Agreement may constitute material and, in some circumstances, non-public information with respect to InfraREIT within the meaning of
U.S. securities laws. Lessee is aware that the U.S. securities laws prohibit any Person who has received from an issuer material non-public information from purchasing or selling securities of such issuer and from communicating such information to
any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities. 

13.4. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon Lessor and Lessee and, to
the extent permitted in any assignment or other transfer under Article VIII, any permitted assignee, and their respective heirs, transferees, successors and assigns, and all persons claiming under them. References to Lessee in this
Agreement shall be deemed to include assignees that hold a direct ownership interest in this Agreement and actually are exercising rights under this Agreement to the extent consistent with such interest. 

13.5. Rent Obligations Not Excused by Force Majeure, Etc. Subject to Section 9.1(b), Lessee shall not be
excused from its obligation to pay Rent during any Force Majeure Event or a condemnation or casualty of all or any part of the Permian Assets. 

13.6. Further Assurances; Policies and Procedures. 

(a) Each Party will, from time to time, execute, cause to be acknowledged and deliver such documents or instruments, and provide such
certificates, as the other Party may reasonably request to carry out and fulfill the transactions, and permit the exercise and performance of the rights and obligations, as are contemplated hereunder. Each Party will cooperate with the other Party
to effectuate fully the purposes and intent of this Agreement. In no way limiting the foregoing, the Parties shall cooperate to obtain any necessary regulatory approvals, including providing timely responses to discovery requests, participating in
regulatory proceedings to the extent necessary and generally providing assistance as required.

 PERMIAN LEASE AGREEMENT 

 (b) From time to time, the Parties shall agree to policies and procedures regarding matters
arising under this Agreement including the treatment of Capital Expenditures for canceled Footprint Projects, each Party’s reporting obligations and such additional matters as the Parties may identify (the “Policies and
Procedures”). The Parties agree to cooperate and negotiate in good faith the Policies and Procedures, and any amendment or revision thereto that may be reasonably requested by either Party, in each case taking into account InfraREIT’s
reporting obligations as a public company, InfraREIT’s qualification as a REIT under the Code and Lessee’s obligations as a regulated utility, and to memorialize the same in a writing executed by a representative of each Party. 

13.7. Arbitration. Except for a dispute regarding the payment of Undisputed Rent, any dispute under this Agreement shall,
if not resolved by the Parties within ninety (90) days after notice of such dispute is served by one Party to the other (or, if different, the period provided for resolution by the Parties in the provision of this Agreement under which such
dispute is brought), be submitted to an “Arbitration Panel” comprised of three (3) members. No more than one (1) panel member may be with the same firm, and no panel member may have an economic interest in the outcome of
the arbitration. In addition to the foregoing, the failure by Lessee and Lessor to reach an agreement or make a mutual determination or characterization required by Sections 2.2(b); 2.3; 3.1; 3.2; 3.3;
3.4(c); 10.5(b) or 13.6(b), in each case after sixty (60) days of negotiating in good faith, shall be deemed to be a “dispute” for purposes of this Section 13.7, to be resolved in accordance with this
Section. 
 (a) The Arbitration Panel shall be selected as follows: Within five (5) Business Days after the expiration of the period
referenced above, Lessee shall select its panel member meeting the criteria of the above paragraph (the “Lessee Panel Member”) and Lessor shall select its panel member meeting the criteria of the above paragraph (the “Lessor
Panel Member”). If a Party fails to timely select its respective panel member, the other Party may notify such Party in writing of such failure, and if such Party fails to select its respective panel member within three (3) Business Days
from such notice, then the other Party may select such panel member on such Party’s behalf. Within five (5) Business Days after the selection of the Lessor Panel Member and the Lessee Panel Member, the Lessee Panel Member and the Lessor Panel
Member shall jointly select a third panel member meeting the criteria of the above paragraph (the “Third Panel Member”). If the Lessor Panel Member and the Lessee Panel Member fail to timely select the Third Panel Member and such
failure continues for more than three (3) Business Days after written notice of such failure is delivered to the Lessor Panel Member and Lessee Panel Member by either Lessor or Lessee, either Lessor or Lessee may request the managing officer of the
American Arbitration Association to appoint the Third Panel Member. 
 (b) Within ten (10) Business Days after the selection of the
Arbitration Panel, each Party shall submit to the Arbitration Panel a written statement identifying its summary of the issues and claims, including, if applicable, its calculation of Rent. Any Party may also request an evidentiary hearing on the
merits in addition to the submission of written statements. The Arbitration Panel shall make its decision within twenty (20) days after the later of (i) the 

  
 36 

 PERMIAN LEASE AGREEMENT 

 
submission of such written statements of particulars, and (ii) the conclusion of any evidentiary hearing on the merits, and shall take into consideration the relative risks and rewards
undertaken and capital invested by each Party and shall use the Comparable Rate of Return concept in determining any Rent disputes. The Arbitration Panel shall reach its decision by majority vote and shall communicate its decision by written notice
to the Parties. 
 (c) The decision by the Arbitration Panel shall be final, binding and conclusive and shall be non-appealable and
enforceable in any court having jurisdiction. All hearings and proceedings held by the Arbitration Panel shall take place in Dallas, Texas. 

(d) The resolution procedure described herein shall be governed by the Commercial Rules of the American Arbitration Association and subject to
the Texas General Arbitration Act to the extent such act is applicable hereto. 
 (e) In the case of an arbitration proceeding involving a
determination of Rent, until Rent has been finally determined, Lessee shall pay Rent (including any Percentage Rent) based upon prevailing rates therefor, and an appropriate refund shall be made to or additional Rent shall be paid by Lessee within
ten (10) days after a final determination is made. 
 (f) The Parties shall bear equally the fees, costs and expenses of the
Arbitration Panel in conducting the arbitration. 
 13.8. Notices. All notices or other communications required or
permitted by this Agreement shall be in writing and may be personally served, sent via facsimile, sent via electronic mail or sent by United States mail or by commercial courier and shall be deemed to have been given when received at the address set

 13.9. Entire Agreement; Termination of Amended and Restated Lease; Amendments.
 
 (a) This Agreement and the Policies and Procedures constitute the entire agreement between Lessor and Lessee
respecting the subject matter hereof, and supersede any and all oral or written agreements. Any agreement, understanding or representation between Lessor and Lessee respecting the Permian Assets, or any other matter referenced herein not expressly
set forth in this Agreement, in the Policies and Procedures or in a subsequent writing signed by both Parties is null and void. 
 (b)
Subject to the remainder of this Section 13.9(b), the Amended and Restated Lease is hereby terminated as of the Effective Date. Notwithstanding the termination of the Amended and Restated Lease pursuant to this
Section 13.9(b), the Parties agree and acknowledge that the provisions of the Amended and Restated Lease that are intended to survive the expiration or termination of the Amended and Restated Lease, including Section 3.2(c)(i),
Section 3.9 and Article XII of the Amended and Restated Lease, shall remain in full force and effect. Without limiting the foregoing, the Parties agree, in accordance with Section 3.2(c)(i) of the Amended and Restated Lease, to conduct a

(c) This Agreement shall not be modified or amended except in a writing signed by both Parties. No purported modifications or amendments,

 PERMIAN LEASE AGREEMENT 

 13.10. Legal Matters. This Agreement shall be governed by and interpreted in
accordance with the laws of the State of Texas, without regard to its conflicts of law principles. The Parties agree that any rule of construction to the effect that ambiguities are to be resolved in favor of either Party shall not be employed in
the interpretation of this Agreement and is hereby waived. 
 13.11. Partial Invalidity. Should any provision of this
Agreement be held, in a final and unappealable decision by a court of competent jurisdiction, to be either invalid, void or unenforceable, the remaining provisions hereof shall remain in full force and effect, unimpaired by the holding. 

13.12. Recording. Lessee shall not record this Agreement without the prior written consent of Lessor, which consent shall
not be unreasonably withheld or delayed. Lessee may record at its expense a memorandum of this Agreement in form and substance reasonably approved by Lessor. In such case, upon the expiration or termination of this Agreement, Lessee shall promptly
record at its expense a memorandum of termination of this Agreement in form and substance reasonably approved by Lessor. 
 13.13.
Intention of Parties; True Lease. 
 (a) The Parties hereby declare that their relationship in and to the Permian
Lease Assets is and will be that of lessor and lessee, expressly subject to the terms, conditions, limitations and requirements set forth in this Agreement. Nothing contained in this Agreement will be deemed to constitute the Parties as partners or
joint venturers or as principal and agent. The Parties intend for this Agreement to constitute a true lease with respect to the Permian Lease Assets for U.S. federal, state and local income tax purposes, and each Party shall treat, and shall cause
its affiliates to treat, the Agreement as a true lease with respect to the Permian Lease Assets for U.S. federal, state and local income tax reporting purposes. 

(b) The Parties acknowledge that Lessor is indirectly owned, in part, by InfraREIT, which qualifies as a REIT under the Code, and the Parties
agree to negotiate in good faith any modification or amendment to this Agreement requested by Lessor to facilitate such qualification; provided that Lessee shall not be obligated to agree to any such modification or amendment if such
modification or amendment would materially adversely affect Lessee or would be in conflict with Applicable Law. Notwithstanding anything to the contrary in this Agreement (including Section 13.3), Lessor may disclose to InfraREIT, and
InfraREIT may disclose to any taxing authority, any information that Lessor or InfraREIT believes is relevant to supporting or maintaining InfraREIT’s qualification as a REIT. 

13.14. Rules of Construction. As used herein, the singular shall be deemed to include the plural, and the plural shall be
deemed to include the singular, and all pronouns shall include the masculine, feminine and neuter, whenever the context and facts require such construction. The headings, captions, titles and subtitles herein are inserted for convenience of
reference only and shall not affect the interpretation of this Agreement. Except as otherwise indicated herein, all section, appendix, exhibit and schedule references in this Agreement shall be deemed to refer to the sections, appendices, exhibits
and schedules of and to this Agreement, and the terms “herein,” “hereof,” “hereto,” “hereunder” and words of similar import refer to this Agreement as a whole rather than to the particular provision in which
such term is used. Whenever the words 

  
 39 

 PERMIAN LEASE AGREEMENT 

 
“including,” “include” or “includes” are used in this Agreement, they shall be interpreted in a non-exclusive manner as though the words “but [is] not limited
to” immediately follow the same. The language in all parts of this Agreement shall in all cases be construed simply according to the fair meaning thereof and not strictly against the Party that drafted such language. Except as otherwise
provided herein, references in this Agreement to any agreement, instrument or other document are to such agreement, instrument or other document as amended, modified or supplemented from time to time.

Exhibit D prior to the renewal of any insurance coverage contemplated hereby, and, as a result of such review, Lessor may waive the requirements set forth herein, if, in Lessor’s reasonable discretion, such coverage limits are not

	(3)	“Allocated Other Revenue” means the portion of Other Revenue that Lessee and Lessor agree to characterize as Allocated Other Revenue under this Agreement pursuant to Section 3.2(e).

related to Allocated Other Revenue) or (y) Revenues Attributable to Lessee CapEx, in each case under this Agreement or any other Lease; (ii) Excluded Revenues under this Agreement or any other Lease or (iii) generated from the Rate
Base of regulated assets owned or operated by a party other than Lessor or a subsidiary thereof.

assets, other than any Excluded Revenues.

determination by the Internal Revenue Service with respect to the PLR Request; (c) any items that are of a pure pass-through nature where such items are charged to and collected from customers of Lessee but that carry regulatory responsibility
to remit such collections without offset or deduction to a third party, including items such as (i) sales taxes or other charges collected by Lessee on behalf of a taxing authority; (ii) 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 similar to the system benefit fund and transmission cost recovery factor collected by distribution service providers; (iii) fees, charges and
other revenues collected by Lessee that can be specifically traced to any deferred costs funded entirely by Lessee that have been ordered or permitted by the PUCT to be recovered through a tariff rider; and (iv) such other items that Lessor and
Lessee agree in good faith are consistent with the foregoing and should be excluded from ERCOT Transmission Revenues or Additional Permian Revenues, as applicable, for purposes of this Agreement; or (d) any item (as mutually agreed by the
Parties) that is based on the income or profits of any Person if, as a consequence thereof, the inclusion of such amount in “Gross Revenues” would cause the Rent to fail to qualify in whole or in part as “rents from real
property” within the meaning of Section 856(d) of the Code. 

  

	(7)	“Other Revenue” means revenue generated from activities as a regulated utility within the State of Texas other than Covered Revenue.
