WITNESSETH: 
 WHEREAS,
Lessor and Lessee were parties to a Lease Agreement, entered into as of July 13, 2010, as amended, restated and supplemented to date, pursuant to which Lessor leased assets known as the FERC Assets to Lessee (the “FERC Lease
Agreement”); 
 WHEREAS, Lessee was subject to an Agreed Transfer Option issued by the PUCT pursuant to PUCT Docket No. 37990,
which provided that the PUCT could order all the FERC Assets to be moved from the SPP to ERCOT by 2014, at which time the FERC Assets would no longer be subject to FERC jurisdiction; 

WHEREAS, the PUCT has ordered the FERC Assets to be moved from SPP to ERCOT and all necessary regulatory approvals for the Agreed Transfer
Option have been obtained; 
 WHEREAS, the FERC Assets have been moved to ERCOT and are subject to PUCT jurisdiction and are no longer
subject to FERC jurisdiction; 
 WHEREAS, Section 2.4 of the FERC Lease Agreement provided that once the FERC Assets had been moved to
ERCOT, the Parties could to terminate the FERC Lease Agreement and Lessor and Lessee could enter into a new lease for the FERC Assets; 

WHEREAS, Lessor is an indirect subsidiary of InfraREIT Partners, LP, whose general partner (the “REIT”) intends to
raise equity capital through an initial public offering (the “REIT IPO”), and, in connection with the REIT IPO, Lessor and Lessee desire to amend the terms of the FERC Lease Agreement in certain respects; 

WHEREAS, consistent with Section 2.4 of the FERC Lease Agreement, Lessor and Lessee wish to enter into an amended and restated lease for
the FERC Assets, now known as the “Stanton Transmission Loop Assets”; and 
 WHEREAS, instead of entering in to a new lease
agreement related to the Stanton Transmission Loop Assets, the Parties have decided to amend and restate the FERC Lease; 
 NOW, THEREFORE,
in consideration of the premises and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto hereby amend and restate the terms of the FERC Lease as follows: 

  
 STANTON
TRANSMISSION LOOP LEASE AGREEMENT 

 ARTICLE I 

LEASE 
 1.1.
Lease of Stanton Transmission Loop 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 integrated electrical transmission facilities that comprise Lessor’s 138kv transmission loop around the Stanton Service Territory and that are connected to the ERCOT electric grid
owned by Lessor and located within the area depicted on Exhibit A, together with the exclusive right to occupy and use all of Lessor’s interest (whether by fee ownership, easement, lease, sublease, franchise or license) (other than to
the extent expressly reserved to Lessor herein) in the premises upon which such facilities are situated (collectively, the “Stanton Transmission Loop Assets”). Subject to necessary regulatory approvals, this Agreement is intended by
Lessor and Lessee to be a lease of the Stanton Transmission Loop Assets, as they exist as of the Effective Date. 
 (b) The Stanton
Transmission Loop Assets shall consist of (x) the original assets leased by Lessor to Lessee as of the Effective Date, and (y) any components of the Stanton Transmission Loop Assets that are repaired or replaced pursuant to
Section 6.1. The Stanton Transmission Loop Assets shall consist of each of the following components that are owned or leased by Lessor as of the Effective Date and that comprise part of Lessor’s 138kv transmission loop around the Stanton
Service Territory (specifically excluding any such Lessor-owned assets that are not part of Lessor’s 138kv transmission loop): 

(i) towers and poles affixed to the land, and all necessary and proper foundations, footings, crossarms and other appliances
and fixtures for use in connection with said towers, poles and lines; 
 (ii) overhead, underground and underwater electrical
transmission and communications lines, together with related ductwork and insulators; 
 (iii) distribution transformers
mounted on towers or poles and/or anchored to concrete pads; 
 (iv) 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 Stanton Transmission Loop Assets, and the building housing the foregoing
items; 
 (v) electric meters affixed to buildings or residences or otherwise required to operate the Stanton Transmission
Loop 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 Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, and not otherwise included in Sections 1.1(b)(i) – 1.1(b)(v) above) owned or leased by Lessor; and 

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 2 

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

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

1.3. Absolute Net Lease. This Agreement is intended by the Parties to be an absolute net lease (and, except
as otherwise specified herein, the expenses associated with the lease, servicing, insuring, maintenance, repair and operation of the Stanton Transmission Loop Assets shall be for the account of the Lessee, unless expressly stated that such expenses
are for the account of Lessor or some other person or entity). Other than as expressly provided herein, (a) Lessee’s obligation to make all payments of Rent as and when the same shall become due and payable in accordance with the terms of
this Agreement shall be absolute, irrevocable and unconditional and shall not be affected by any circumstance or subject to any abatement or diminution by set-off, deduction, counterclaim, recoupment, agreement, defense, suspension, deferment,
interruption or otherwise, and (b) until such time as all Rent required to be paid has been paid, Lessee shall have no right to terminate this Agreement or to be released, relieved or discharged from its obligation to make, and shall not
suspend or discontinue, any payment of Rent for any reason whatsoever. 
 1.4. Waiver by Lessee. Lessee
hereby waives, to the extent permitted by Applicable Law, any and all rights which it may now have or which at any time hereafter may be conferred upon it, by statute or otherwise, to modify, terminate, cancel, quit or surrender this Agreement
except in accordance with the express terms hereof. 
 1.5. Quiet Enjoyment. Lessee shall be entitled to
the peaceful and quiet enjoyment of the Stanton Transmission Loop 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, 2021, unless otherwise terminated in a manner consistent herewith (the “Initial Term”). Thereafter, this Agreement may be renewed
for subsequent terms (each, a “Renewal  

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 3 

 
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
negotiated using the Comparable Rate of Return methodology set forth in Article III of the McAllen Lease. Notwithstanding the foregoing, the Parties agree that, in the event that both Parties desire to renew this Agreement upon the expiration of the
Initial Term, it is their intention that this Agreement will be combined with, and the Stanton Transmission Loop Assets shall be covered by, the Stanton/Brady/Celeste Lease. 

2.2. Approvals upon Expiration or Termination 

(a) Notwithstanding any provisions to the contrary herein, Lessee shall not surrender, resign, transfer, assign or otherwise
cease to be the operator of the Stanton Transmission Loop Assets at any time, including upon the termination of this Agreement or at the expiration of the Term, without first acquiring any necessary regulatory approvals from the PUCT or other
Regulatory Authorities regarding such surrender, resignation, transfer, assignment or cessation of such operatorship; provided that, in the event of expiration or termination, the Parties shall use commercially reasonable efforts to obtain all
necessary regulatory approvals of the transfer of such operatorship as soon as reasonably practicable. 
 (b) During such
extended period of operatorship, Lessee shall continue to operate the Stanton Transmission Loop Assets and shall continue to pay all Extended Period Rent; provided, however, that if regulatory approval is not obtained within twelve (12) months
of initiation of the approval process and such delay is (a) due to Lessor’s failure to reasonably pursue such approval, then the amounts payable as Rent will be eighty percent (80%) of such amount, or (b) due to Lessee’s
failure to reasonably pursue such approval, then the amounts payable as Rent will be one hundred five percent (105%) of such amount. 

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

 ARTICLE III 

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

(b) Lessee shall pay to Lessor an amount of base rent equal to the amount set forth on the rent supplement executed and delivered by the
Parties in connection herewith, which shall be payable monthly in arrears 45 days after the conclusion of the month (“Base Rent”). The Parties acknowledge that such rent supplement also provides for a one-time payment by Lessor to
Lessee, calculated in the manner described therein, as a reimbursement for excess rent paid by Lessee for the period from May 1, 2014 through the Effective Date. 

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

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

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

LESSEE’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

Lessee hereby represents, warrants and covenants to Lessor that: 

4.1. Maintenance, Operation and Repair of the Stanton Transmission Loop Assets. 

(a) Lessee, at its own cost and expense, shall maintain (including both scheduled and unscheduled maintenance), operate, repair and make all
modifications (other than Footprint Projects) to the Stanton Transmission Loop 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 Stanton Transmission Loop Assets, in each case, as reasonable and prudent and consistent with Good Utility Practice and as required by Applicable Law. Lessee 

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 5 

 
shall carry out all obligations under this Agreement as reasonable and prudent and consistent with Good Utility Practice and in accordance with manufacturers’ warranty requirements (during
any applicable warranty period) and the Lessee’s established operating procedures and maintenance, rebuild and repair programs so as to keep the Stanton Transmission Loop 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 Stanton Transmission Loop Assets in a reliable and safe manner in compliance with all applicable requirements and regulations of Regulatory
Authorities. Lessee will not operate the Stanton Transmission Loop 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 Stanton Transmission Loop Assets by Lessor show that the Stanton Transmission Loop 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 Stanton Transmission Loop Assets can be modified to comply with the standards, and (ii) complete any and all such modifications consistent with all applicable reliability and safety standards established by
regulations, orders or requirements of Regulatory Authorities. 
 4.2. Licenses and Permits. Lessee shall
obtain and maintain any and all licenses, permits and other governmental and third-party consents and approvals required by Applicable Law in order to carry out its obligations under this Agreement. 

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

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT

 4.4. Requirements of Governmental Agencies and Regulatory Authorities.
Lessee, at its expense, shall comply with all Applicable Laws, including without limitation all requirements of the Regulatory Authorities. Lessee shall have the right, in its reasonable discretion and at its cost and expense, to contest by
appropriate legal proceedings, the validity or applicability to the Stanton Transmission Loop Assets of any Applicable Law made or issued by any federal, state, county, local or other governmental agency or entity. Any such contest or proceeding
shall be controlled and directed by Lessee. Notwithstanding the foregoing, Lessee shall provide Lessor written notice of the commencement and, at reasonable intervals after commencement, the progress of any such legal proceedings. 

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

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

(b) Without limiting the generality of the foregoing, Lessee shall not (i) place or locate any underground tanks on the property
underlying the Stanton Transmission Loop Assets, (ii) generate, manufacture, transport, produce, use, treat, store, release, dispose of or otherwise deposit Hazardous Materials in or on the Stanton Transmission Loop Assets, the property
underlying the Stanton Transmission Loop Assets or any portion thereof other than as permitted by Applicable Laws that govern the same or are applicable thereto, (iii) permit any other substances, materials or conditions in, on or emanating
from the Stanton Transmission Loop Assets, the property underlying the Stanton Transmission Loop 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 Stanton Transmission Loop Assets. 

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

 4.7. Indebtedness. Lessee shall not incur
Indebtedness other than: (i) Indebtedness in an aggregate principal amount of up to the greater of (A) $5,000,000 and (B) an amount equal to one percent (1%) of the sum of, without duplication, (x) the total amount of the
Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus (z) the total amount of Leased
Consolidated Net Plant of Lessee, in each case on a senior secured basis, (ii) Indebtedness in an aggregate principal amount of up to the greater of (A) $10,000,000 and (B) an amount equal to one-and-a-half percent (1.5%) of the
sum of, without duplication, (x) the total amount of the Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is party as
a lessee, plus (z) the total amount of Leased Consolidated Net Plant of Lessee, in each case on an unsecured subordinated basis on terms substantially similar to the terms set forth on Exhibit B 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 may incur Indebtedness in an aggregate principal amount of up to the product of
(x) Sharyland’s aggregate Consolidated Net Plant multiplied by (y) the lesser of (A) the sum of Sharyland’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, Sharyland’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 Sharyland in good faith. Without limiting the amount of Indebtedness permitted
by the foregoing, Lessee may also incur Indebtedness (x) in the form of a pledge of equity interests in a subsidiary of Lessee as security for Non-Recourse Debt of such subsidiary and (y) in amounts otherwise permitted under the Debt
Agreements. 
 4.8. Records. Lessee shall maintain proper books of record and account in conformity with GAAP and
all applicable Regulatory Authorities and each other governmental agency or authority having legal or regulatory jurisdiction over Lessee. Additionally, Lessee shall maintain or cause to be maintained all logs, drawings, manuals, specifications and
data and inspection, modification and maintenance records and other materials required to be maintained in respect of the Stanton Transmission Loop 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 expiration of the Term or earlier termination of this Agreement in accordance with its terms
(but subject to Section 2.2 and the requirements of all Applicable Laws), and in a manner calculated to avoid any disruption of electrical service, Lessee shall vacate and surrender possession of all components of the Stanton Transmission Loop
Assets (other than Severable Footprint Projects) to Lessor, or to such other person or entity as Lessor may direct. At the time of such surrender, the Stanton Transmission Loop Assets shall be free and clear of Liens and other rights of third
parties (other than Permitted Liens), and shall be in the same condition as on the Effective Date, ordinary wear and tear excepted. Lessee shall deliver or cause to be delivered to Lessor, or to such other person or entity as Lessor may direct,
copies of all title documents, logs, drawings, manuals, specifications and data and inspection, 

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT

modification and maintenance records, billing records, reports and other documents in respect of the Stanton Transmission Loop Assets which are necessary to determine the condition of the Stanton
Transmission Loop Assets or for the continued maintenance, repair or general operation of the Stanton Transmission Loop Assets and are in Lessee’s possession at such time. In connection with the surrender of the Stanton Transmission Loop
Assets, Lessor shall pay to Lessee the aggregate purchase price for any property and equipment purchased by Lessor in accordance with Section 2.3. 

4.10. Cooperation; Transition Services. 

(a) During the period after notice of termination and prior to the termination of the Agreement, with reasonable notice, Lessee will cooperate
in all reasonable respects with the efforts of Lessor to sell or lease the Stanton Transmission Loop Assets (or any component thereof) or any interest therein, including, without limitation, permitting prospective purchasers or lessees to fully
inspect the Stanton Transmission Loop 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 Stanton
Transmission Loop Assets or cause Lessee to incur any additional expenses other than as specifically provided herein. All information obtained in connection with such inspection shall be subject to confidentiality requirements at least as
restrictive as those contained in Section 13.3. 
 (b) Upon expiration of the Term or termination of this Agreement, Lessee shall
continue to operate the Stanton Transmission Loop Assets pursuant to the terms of Section 2.2, if required thereunder. During such period Lessee shall perform all duties and retain all obligations under Article IV in all respects, as if the
Term had not expired or this Agreement had not been terminated. 
 4.11. Lessee’s Authority. Lessee has all
requisite power and authority to execute and deliver this Agreement and to perform its obligations hereunder. Lessee has taken all action necessary to execute and deliver this Agreement and to perform its obligations hereunder, and no other action
or proceeding on the part of Lessee is necessary to authorize this Agreement. This Agreement constitutes the legally valid and binding obligation of Lessee, enforceable against Lessee in accordance with its terms, except as the enforceability
thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar Applicable Laws affecting the enforcement of creditors’ rights generally and equitable principles. 

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

4.13. Financing. Lessee acknowledges that Lessor has advised Lessee that the Stanton Transmission Loop Assets and this
Agreement are security for the financings described below. In connection with such financings, SDTS made certain representations, warranties and covenants set forth in that certain (i) Amended and Restated Note Purchase Agreement entered into

ARTICLE V 
 LESSOR’S
REPRESENTATIONS, WARRANTIES AND COVENANTS 
 Lessor hereby represents, warrants and covenants as follow: 

5.1. Lessor’s Authority. 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

5.2. Liens. Lessor represents that Lessor has good and valid title to the Stanton Transmission Loop Assets, there are no
unrecorded liens, encumbrances, leases, mortgages, deeds of trust (except as disclosed to Lessee in writing or as arise by operation of law), or other exceptions (collectively, “Liens”) arising as a result of any acts or omissions
to act of Lessor by, through or under Lessor to Lessor’s right, title or interest in the Stanton Transmission Loop Assets other than any such of the foregoing that does not materially impair the Lessee’s use of the Stanton Transmission
Loop Assets, and, to Lessor’s knowledge, there exist no rights or interests of any third party relating to the Stanton Transmission Loop Assets that are not contemplated herein. Except for Permitted Liens or as may be disclosed in the
applicable real property records in the State of Texas, or as disclosed by Lessor in writing to Lessee, Lessor represents that there are no mortgages, deeds of trust, or similar liens or security interests encumbering all or any portion of the
Stanton Transmission Loop Assets. Lessor shall fully cooperate and assist Lessee, at no out-of-pocket expense to Lessor, in obtaining a subordination and non-disturbance agreement from each party that holds a Lien that might reasonably be expected
to interfere in any material respect with Lessee’s rights under this Agreement. Notwithstanding the foregoing and subject to receipt of any regulatory approvals, Lessor and its affiliates shall have the right to incur Permitted Liens
encumbering the Stanton Transmission Loop 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 Stanton Transmission Loop 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 the Lessor may reasonably request. 

5.3. Condition of Assets. Lessor has not taken any action or failed to take any action that would cause the
Stanton Transmission Loop 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 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 required for the maintenance or operation of the Stanton Transmission Loop Assets, including execution of

STANTON TRANSMISSION LOOP LEASE AGREEMENT

 ARTICLE VI 

LOSS AND DAMAGE; INSURANCE 

6.1. Loss and Damage to the Stanton Transmission Loop Assets. 

(a) In the event of any damage or loss to any component of the Stanton Transmission Loop 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). The cost of any such repair or replacement shall be borne as described in
Section 6.1(b)-(c) below. 
 (b) If such repair or replacement constitutes a Repair, the cost of repairing or replacing such damage
or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessee. Lessee shall be entitled to retain any insurance proceeds in excess of the amount necessary to repair or replace any component of the Stanton
Transmission Loop Assets. Any Repair will immediately become part of the Stanton Transmission Loop Assets owned by Lessor. 
 (c) If such
repair or replacement constitutes a Footprint Project, then it will be treated as a Footprint Project under the Stanton/Brady/Celeste Lease (initially), or another lease to which Lessor and Lessee are a party, and addressed pursuant to the terms
thereof. 
 (d) Lessee shall be solely responsible for all costs of repairing or replacing any damaged property and equipment that is not
part of the Stanton Transmission Loop Assets and owned by Lessee, whether covered by Lessee’s insurance under Section 6.2 or otherwise. Nothing in this provision shall preclude Lessee from seeking recovery of such costs in a rate
proceeding at the PUCT. 
 6.2. Insurance. Lessee will maintain, with financially sound and reputable insurers,
insurance with respect to its business and properties and the Stanton Transmission Loop 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 C. 
 (a) Lessee shall procure at its own expense and maintain in full force and effect at all times
throughout the term of this insurance policies with insurance companies rated A-, 8 or higher by A.M. Best or acceptable to Lessor if not so rated, and authorized to do business in the State of Texas. 

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

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 13 

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

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

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

ARTICLE VII 
 REPORTING

 7.1. Private Financing Arrangements. Lessee understands that Lessor, or an affiliate thereof, has raised equity
and debt capital secured by the Stanton Transmission Loop Assets and this Agreement and that Lessor or its affiliates have reporting obligations in connection with such arrangements, including obligations to provide financial statements prepared in
accordance with GAAP, to prepare an annual strategic plan and to update such annual strategic plan in the event of certain material deviations therefrom. Lessee understands that Lessor relies on Lessee in order to comply with such obligations. From
time to time, Lessor or an affiliate thereof may enter into additional arrangements that impose similar obligations. Accordingly, Lessee agrees to provide Lessor in a timely manner audited year-end financial statements, quarterly unaudited financial
statements for the first three quarters of each year (certified by a financial officer of Lessee), and such acknowledgements, certificates, permits, licenses, instruments, documents and other information as Lessor may reasonably request from time to
time in connection with, or to enable Lessor and its affiliates to comply with any such debt or equity financing arrangements or with Applicable Law. The Parties will negotiate in good faith the time frames during which Lessee will provide such
information, with the intention that Lessee provide such information in 

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 14 

 
a manner that is not unduly burdensome but that also allows Lessor sufficient time to comply with its reporting obligations. Lessee will also cooperate with Lessor to enable Lessor to satisfy its
obligations in respect of annual strategic plans, including providing Lessor with requested information in advance of the due date of such annual strategic plan and keeping Lessor apprised of deviations in capital expenditures, construction activity
or revenues of Lessee from amounts that were originally provided by Lessee in preparing such annual strategic plan. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein
in a timely manner and to reasonably cooperate with Lessor to remedy the effects of such non-compliance. 
 7.2. Public Company
and Regulatory Information and Cooperation. 
 (a) Lessee agrees to provide audited full-year and unaudited (but SAS 100 reviewed)
interim financial statements and the consent of Lessee’s auditors to the inclusion of their opinion regarding such financial statements in filings with the Securities and Exchange Commission made by Lessor or an affiliate of Lessor. Lessor may
also request that Lessee provide evidence of a SAS 100 review from Lessee’s auditors with respect to any unaudited interim financial statements included in any such filing. Lessor shall have the right to share any such financial statements with
its lenders under the Debt Agreements. Lessee covenants that (i) such financial statements will fairly present in all material respects the financial condition, results of operations and cash flows of Lessee as of, and for, the periods
presented, and (ii) Lessee will endeavor to cause such financial statements to comply with any applicable laws, rules or regulations that Lessee and Lessor conclude in good faith are applicable to such financial statements by virtue of their
inclusion in the securities law filings of Lessor or an affiliate thereof. 
 (b) Lessee agrees that, in connection with any underwritten
offering of the securities of Lessor or any affiliate thereof, Lessee will use commercially reasonable efforts to cause its auditors to provide a comfort letter (or its equivalent) to such underwriters, if requested by Lessor. 

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

(d) Lessee and Lessor agree to reasonably cooperate to ensure that, to the extent they require information from the other party in order to
prepare their financial statements, to obtain audits of those financial statements and, if required, of their internal control over financial reporting, to respond to comments of the Securities and Exchange Commission on such financial statements or
statements related to internal control over financial reporting or disclosure controls and procedures, or to ensure the efficacy of their internal controls or disclosure controls and procedures, they will reasonably cooperate in order to ensure that
each Party is able to meet its obligations in respect thereof. Lessee agrees to promptly notify Lessor of or provide to Lessor, as applicable, (i) any material communication, written or otherwise, submitted to the Lessee by its auditors,
including, but not limited to an audit response letter, accountant’s management letter or other written report submitted to Lessee by its accountants or any governmental agency in connection with an annual or interim audit of Lessee’s
books, (ii) any material correspondence with, reports of or reports to any Regulatory Authority with respect to the Stanton Transmission Loop Assets and (iii) any notices of violations of Applicable Law with respect to the Stanton
Transmission Loop Assets, in each case taking into account the REIT’s reporting obligations as a public company. 

  

STANTON TRANSMISSION LOOP LEASE AGREEMENT 

  
 15 

 (e) Lessor agrees to inform Lessee of the time periods in which each of the items identified in
this Section 7.2 will be required, which may change. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and to reasonably cooperate with
Lessor to remedy the effects of such non-compliance. 
 (f) If Lessor identifies additional matters with respect to which Lessee input,
assistance or information is required in order for Lessor and its affiliates to comply with any applicable securities laws, the rules or regulations of any exchange on which the securities of such affiliate are traded or any similar laws, rules or
regulations, the Parties agree to cooperate and negotiate in good faith in order to determine the manner in which Lessee can provide such input, assistance or information in a manner that positions Lessor and its affiliates to comply in a timely
manner with such laws, rules or regulations, as efficiently as is feasible so as to minimize the burden that the provision of such input, assistance or information imposes on Lessee. 

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

ASSIGNMENT 
 This Agreement
shall not be assignable by either Party, nor shall the Stanton Transmission Loop Assets or any part thereof be subleased by Lessee, except with the prior written consent of the other Party and the prior approval of any Regulatory Authority whose
approval is required for the effectiveness of such assignment or sublease. For purposes of this Article VIII, an “assignment” by Lessee shall mean and include, in addition to any direct transfer by Lessee to a third party of all or any
part of Lessee’s rights, estate or interests under this Agreement, any direct or indirect, voluntary or involuntary transfer of or encumbrance on all or any part of Lessee’s rights, estate or interests under this Agreement (i) by
operation of law and/or (ii) by direct or collateral transfer of all or any part of the legal or beneficial ownership interest in Lessee by merger, consolidation or otherwise, provided, in the case of clause (ii), any such transaction or
transactions will only constitute an assignment hereunder to the extent they result in a Change of Control. Notwithstanding the foregoing, Lessor shall have the right, without Lessee’s consent but subject to obtaining regulatory approval as
described in the foregoing sentence, (a) to assign, pledge or grant a security interest in any or all of its interest in this Agreement to a lender or lenders, or a trustee acting on behalf of such lenders, in connection with a financing or
refinancing in which such interest is pledged as collateral, and Lessee agrees to enter into such acknowledgments and agreements in respect thereof as the Lessor may reasonably request and (b) to assign its interest in this Agreement to a
successor owner of the Stanton Transmission Loop Assets.

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

(g) Notwithstanding Section 9.1(a), Lessee’s failure to pay Rent when due shall not constitute a default if (i) such failure is

unforeseen material decline in electricity usage as a result of such an 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,

 SECOND AMENDED AND RESTATED 

LEASE AGREEMENT 

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

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

WITNESSETH: 
 WHEREAS,
Lessor and Lessee entered into that certain Amended and Restated Lease Agreement dated as of April 30, 2013 (as amended, restated, supplemented or otherwise modified from time to time, the “Amended and Restated Lease”),
pursuant to which Lessee leases the CREZ Lease Assets from Lessor; and 
 WHEREAS, Lessor is an indirect subsidiary of InfraREIT
Partners, LP, whose general partner (the “REIT”) intends to raise equity capital through an initial public offering (the “REIT IPO”), and, in connection with the REIT IPO, Lessor and Lessee desire to amend the terms
of the Amended and Restated Lease in certain respects and restate the Amended and Restated Lease as so amended; 
 NOW, THEREFORE, in
consideration of the premises and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Parties hereto hereby amend and restate the terms of the Amended and Restated Lease as follows: 

ARTICLE I 
 LEASE

 1.1 Lease of CREZ 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 CREZ
Lease Assets. Subject to necessary regulatory approvals and the penultimate sentence of this Section 1.1, this Agreement is intended by Lessor and Lessee to be a master lease of the CREZ Lease Assets, as it existed as of June 20, 2011 (the
“Original Lease Date”), as it has been altered by the completion of the construction of the CREZ Project and as it has been or may continue to be altered or expanded thereafter by Footprint Projects in which Lessor has an interest.

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 1 

 (b) The CREZ Assets shall consist of the Transmission Lines and the Collection Stations and each
of the following components which are owned by Lessor as of the date hereof (or that are included within the CREZ Assets by virtue of clause (i), (ii) or (iii) of the definition thereof) and that are located within the area depicted on
Exhibit A: 
 (i) towers and poles affixed to the land, and all necessary and proper foundations, footings, crossarms
and other appliances and fixtures for use in connection with said towers, poles and lines; 
 (ii) overhead, underground and
underwater electrical distribution, transmission and communications lines, together with related ductwork and insulators; 

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

(iv) electric meters required to operate the CREZ Assets; 

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

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

The CREZ Assets exclude, for avoidance of doubt, the Transmission Operation Center and the transmission and distribution related assets included in the Backup
Operations Center located in Amarillo, Texas, which are currently owned by SDTS (Lessor’s parent entity) and leased to Lessee pursuant to the McAllen Lease. Notwithstanding anything to the contrary in this Agreement, the parties do not intend
or agree to enter into a lease with respect to any Footprint Project or other alteration, expansion or addition to the CREZ Assets (and the Lessee shall not be authorized to use or operate such Footprint Project, alteration, expansion or addition to
the CREZ 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 “CREZ Assets” rely on the assumption that this is the case. 
 1.2 Exclusive
Rights. Throughout the Term of this Agreement, Lessee shall have the exclusive right (i) to operate and use the CREZ Lease Assets for the transmission of electricity in accordance with applicable rules and
regulations of all regulatory agencies having regulatory jurisdiction over the CREZ Assets, including without limitation, the PUCT, as well as applicable rules and regulations of ERCOT, TRE, NERC and other Regulatory

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 2 

 
Authorities, and (ii) to utilize the CREZ Lease Assets (and the associated easements, rights of way and similar rights) for other opportunities and uses (provided that such other uses do not
interfere with the current or future transmission and delivery of electricity), subject to the approval of the Lessor, such approval not to be unreasonably withheld, conditioned or delayed. Throughout the Term of this Agreement, Lessor shall have
access to the CREZ Assets at all reasonable times for purposes of inspection and for the purposes of improving, expanding or modernizing the CREZ Assets in accordance with Article X. Except in the case of emergency, prior to Lessor’s access of
the CREZ Assets, Lessor will provide written notification to Lessee’s operations personnel. 
 1.3 Absolute Net
Lease. This Agreement is intended by the Parties to be an absolute net lease (and, except as otherwise specified herein, the expenses associated with the lease, servicing, insuring, maintenance, repair and
operation of the CREZ Assets shall be for the account of the Lessee, unless expressly stated that such expenses are for the account of Lessor or some other person or entity). Other than as expressly provided herein, (a) Lessee’s obligation
to make all payments of Rent as and when the same shall become due and payable in accordance with the terms of this Agreement shall be absolute, irrevocable and unconditional and shall not be affected by any circumstance or subject to any abatement
or diminution by set-off, deduction, counterclaim, recoupment, agreement, defense, suspension, deferment, interruption or otherwise, and (b) until such time as all Rent required to be paid has been paid, Lessee shall have no right to terminate
this Agreement or to be released, relieved or discharged from its obligation to make, and shall not suspend or discontinue, any payment of Rent for any reason whatsoever. 

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

1.5 Quiet Enjoyment. Lessee shall be entitled to the peaceful and quiet enjoyment of the CREZ 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 became effective on the Original Lease Date and shall continue through December 31, 2020 unless otherwise terminated in a manner consistent herewith (the “Initial Term”). Thereafter, this
Agreement may be renewed for subsequent terms (each, a “Renewal Term” and, collectively with the Initial Term, the “Term”) by mutual agreement of the Parties;
provided, however, that the Rent for any Renewal Term shall be targeted to provide the Lessor with a Comparable Rate of Return on the then-current Rate Base of the CREZ Assets.

 2.2 Approvals upon Expiration or Termination. 

(a) Notwithstanding any provisions to the contrary herein, Lessee shall not surrender, resign, transfer, assign or otherwise cease to be the
operator of the CREZ Assets at any time, including upon the termination of this Agreement or at the expiration of the Term, without first acquiring any necessary regulatory approvals from the PUCT or other Regulatory Authorities regarding such
surrender, resignation, transfer, assignment or cessation of such operatorship; provided that, in the event of expiration or termination, the Parties shall use commercially reasonable efforts to obtain all necessary regulatory approvals of the
transfer of such operatorship as soon as reasonably practicable. 
 (b) During such extended period of operatorship, Lessee shall continue to
operate the CREZ Assets and shall continue to pay all Extended Period Rent; provided, however, that if regulatory approval is not obtained within twelve (12) months of initiation of the approval process and such delay is (a) due to
Lessor’s failure to reasonably pursue such approval, then the amounts payable as Rent will be eighty percent (80%) of such amount, or (b) due to Lessee’s failure to reasonably pursue such approval, then the amounts payable as
Rent will be one hundred five percent (105%) of such amount. 
 (c) Upon the expiration of the Term or termination of this Agreement,
Lessee shall use commercially reasonable efforts to obtain all necessary regulatory approvals as soon as reasonably practicable from the PUCT or other Regulatory Authorities to transfer or assign the CCNs for the CREZ Assets to Lessor or a third
party designated by Lessor and acceptable to the PUCT or other Regulatory Authorities. 
 2.3 Purchase Option upon Expiration or
Termination. Upon the expiration of the Term or termination of this Agreement, Lessor shall have the option to purchase from Lessee any equipment or other property, tangible or intangible, owned by Lessee and
principally used in connection with and necessary for the operation of the CREZ Assets (including any Nonseverable Footprint Projects owned by Lessee, if any), subject to any required regulatory approvals. The purchase price for such property or
equipment shall be the greater of (i) the net book value thereof plus 10% and (ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail to agree on the amount of the purchase price,. the
purchase price shall be determined by arbitration pursuant to Section 13.7. In the event Lessor purchases such equipment, Lessee shall have the right to continue to use such equipment for no cost during the period of any extended operations by
Lessee under Section 2.2. 
 ARTICLE III 

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

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 4 

 (a) Base Rent: Lessee will pay Lessor an amount of base rent equal to the amount set forth
on the then-effective Rent Supplement executed and delivered in connection herewith, which shall be payable monthly in arrears 45 days after the conclusion of the month. The amount of base rent owed pursuant to this Section 3.1(a) may be
supplemented by the Parties from time to time in accordance with Section 3.2. The amount of base rent payable pursuant to this Section 3.1(a), as supplemented from time to time pursuant to Section 3.2, is referred to as “Base
Rent.” 
 (b) Percentage Rent: In addition to the Base Rent set forth above, Lessee covenants and agrees to pay to
Lessor, as percentage rent, an annual amount equal to the percent of Gross Revenues during the applicable Lease Year in excess of the Annual Percentage Rent Breakpoint for such Lease Year, all as set forth on the then-effective Rent Supplement. The
percentage amounts used for the calculation of percentage rent owed pursuant to this Section 3.1(b) (the “Percentage Rent Percentages”) may be supplemented by the Parties from time to time in accordance with Section 3.2 to
account for additions to the CREZ Assets. The percentage rent payable pursuant to this Section 3.1(b), as supplemented from time to time pursuant to Section 3.2, is referred to as “Percentage Rent.” 

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

(d) Gross Revenues: 
 (i)
As used in this Agreement, subject to Section 3.1(d)(ii), the “Gross Revenues” of the CREZ Assets shall mean and include all fees, charges and other revenues generated by or otherwise (x) received by or payable to Lessee
in connection with or which are the result of the operation of the CREZ Assets (and any assets related to the CREZ Assets owned by Lessee), as set forth in the FERC Uniform System of Accounts for electric utilities or such other accounts as may be
applicable from time to time in which Lessee records its revenues from operation of the CREZ Assets; (y) received by or payable to Lessee from other opportunities and uses of the CREZ Assets pursuant to Section 1.2 hereof; or (z) that
are insurance proceeds for business income lost from an insured event related to the CREZ Assets; provided that, “Gross Revenues” shall not include (1) any payment received by Lessee as CIAC; (2) any items which are of a
pure pass-through nature where such items are charged to and collected from customers of Lessee but which carry regulatory responsibility to remit such collections without offset or deduction to a third party, including, but not limited to, items
such as: (A) sales taxes or other charges collected by Lessee on behalf of a taxing authority; (B) fees, charges and other revenues collected by Lessee that can be specifically traced to any regulatory approved costs incurred by Lessee
that have been ordered or permitted by the PUCT to be recovered through Lessee’s rates such as system benefit funds; (C) fees,  

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 5 

 
charges and other revenues collected by Lessee that can be specifically traced to any deferred costs funded by Lessee that have been ordered or permitted by the PUCT to be recovered through a
tariff rider; and (D) such other items that Lessor and Lessee agree to in good faith are consistent with the foregoing and should be included prospectively in the list set forth in this clause (2) and in the event the Lessor and Lessee
cannot agree on what items should be included on such list after 60 days of negotiating in good faith, then either Lessor or Lessee may submit such matter to arbitration pursuant to Section 13.7 of this Agreement, pursuant to which the
Arbitration Panel shall be empowered to determine which such items shall be included on such list, based on submissions by each of the Lessee and the Lessor; and (3) Revenues Attributable to Lessee CapEx. The term “Unadjusted Gross
Revenues” means the amount of Gross Revenue, calculated in accordance with this Section 3.1(d)(i), without giving effect to the offset set forth in clause (3), above, related to Revenues Attributable to Lessee CapEx. 

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

  
 CREZ
ASSETS LEASE AGREEMENT

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

(e) Payment of Percentage Rent: Percentage Rent shall be paid by Lessee to Lessor not later than the date forty-five (45) days after the
end of each Lease Quarter as herein provided. Lessee shall record Gross Revenues in order to provide an audit trail for the Gross Revenues. Lessee shall deliver a written statement to Lessor, accompanied by a CFO Certificate, within forty-five
(45) days after the end of each Lease Quarter, stating (1) the Gross Revenues for that Lease Quarter, (2) the cumulative total through the end of that Lease Quarter of Gross Revenues for such Lease Year, (3) the Percentage Rent
Breakpoint (the First Lease Quarter Percentage Rent Breakpoint, the Second Lease Quarter Percentage Rent Breakpoint, the Third Lease Quarter Percentage Rent Breakpoint or the Annual Percentage Rent Breakpoint for such Lease Year, as applicable),
utilized by Lessee and applicable to 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 7 

 
Lessee’s calculation of Percentage Rent through the end of that Lease Quarter, and (4) the cumulative total of any Percentage Rent then due and the cumulative total of any Percentage
Rent previously paid with respect to any prior Lease Quarter(s) within such Lease Year. If such CFO Certificate indicates that any Percentage Rent is due for such Lease Quarter (or such Lease Year, as applicable), based upon the cumulative total of
Gross Revenues through the end of such Lease Quarter and the applicable Percentage Rent Breakpoint reflected in such statement, then Lessee shall pay and deliver any Percentage Rent then due with the statement and CFO Certificate for such Lease
Quarter (or such Lease Year, as applicable). With respect to the final Percentage Rent calculation for any Lease Year, Lessee shall receive a credit for any Percentage Rent previously paid with respect to such Lease Year. If the Percentage Rent
payments previously made by Lessee to Lessor for the first three Lease Quarters of a Lease Year, on a cumulative basis, exceed the annual amount of Percentage Rent payable by Lessee to Lessor for such Lease Year, then Lessee shall receive a credit
for such excess amount against the next Percentage Rent payment(s) becoming due and payable by Lessee to Lessor under this Agreement. All statements deliverable by Lessee to Lessor under this Agreement shall be delivered to the place where rent is
then payable, or to such other place or places as Lessor may from time to time direct by written notice to Lessee. 
 3.2 Rent
Supplements. 
 (a) The Parties have executed a Rent Supplement with respect to the Rent in effect as of the Effective Date.
This Section 3.2(a) will not require any amendment to Rent unless the Parties expect Incremental CapEx and the Parties have not previously entered into a Rent Supplement with respect to such Incremental CapEx. If the Parties expect Incremental
CapEx, then they will negotiate in good faith to supplement Rent and other matters in accordance with this Section 3.2. In connection therewith, the Parties will negotiate the pre-tax rate of return that Lessor should earn on such Incremental
CapEx, which will be based generally on an agreed-to-discount from the rate of return that public utility companies generally earn in the State of Texas at the time of such Rent Supplement negotiation, adjusted in the manner agreed to by the Parties
(if justified) to take into account the creditworthiness of Lessee at the time of such Rent Supplement negotiation (the “Agreed-to-Discount”). Such discount will be based on the
comparable discount agreed to in connection with the negotiation of rent pursuant to the McAllen Lease and other leases between Lessee and SDTS (or an affiliate thereof), as modified to take into account appropriate factors at the time of such Rent
Supplement negotiation. Such pre-tax rate of return, as determined in accordance with this paragraph, is referred to as a “Comparable Rate of Return.” The following will apply to the determination of the matters set forth on the
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 its Incremental CapEx. Such Comparable Rate of Return will be achieved by a split between Base Rent and Percentage Rent in the proportions requested by Lessor and agreed to by Lessee. 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 8 

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

(iii) Notwithstanding anything herein to the contrary, such supplement shall be determined solely to provide a Comparable Rate
of Return on such Incremental CapEx and shall not be determined with reference to, or with any intention to true up, the effect of any difference between the initially anticipated and the actual return of or on, or the Base Rent or Percentage Rent
payable with respect to, the CREZ Assets as in place prior to the additions resulting from such Incremental CapEx. 
 (iv)
Notwithstanding the foregoing, the aggregate Base Rent provided for in the Rent Supplements for the Transmission Lines and the Collection Stations shall not be less than the amount necessary for the Lessor to demonstrate a Debt Service Coverage
Ratio of not less than 1.25x for each calendar quarter falling during the terms of such Rent Supplements. 
 (b) The Parties will memorialize
the results of any Incremental CapEx supplements and Lessee CapEx supplement negotiations by executing and delivering a Rent Supplement, which will set forth the amount of contemplated Incremental CapEx, new Base Rent, a new Percentage Rent
Schedule, new Revenues Attributable to Lessee CapEx, Lessee CapEx, new TCOS Allocation (if applicable), the effective date on which such changes will occur and the term of such Rent Supplement (if applicable). In no event will any new Base Rent or
new Percentage Rent be payable, or any Revenues Attributable to Lessee CapEx be taken into account as a reduction to Unadjusted Gross Revenues, before the assets funded by the related Incremental CapEx or Lessee CapEx are placed in service. The Rent
Supplement may also include the projected in-service date of the Incremental CapEx or Lessee CapEx to which the Rent Supplement applies. Upon execution and delivery of any such Rent Supplement, this Agreement will be deemed amended thereby. If
necessary, Exhibit A will be supplemented to reflect new assets funded by Incremental CapEx. The Rent Supplement shall have the term set forth therein, not to extend past the then-current Term of this Agreement. At the end of the term of each
Rent Supplement, the Parties shall negotiate a new Rent Supplement for the Lessee CapEx and Incremental CapEx covered by such prior Rent Supplement using the Comparable Rate of Return methodology set forth in Sections 3.1(d)(iii) and 3.2(a).
Notwithstanding the foregoing, the Percentage Rent Percentages and Annual Percentage Rent Breakpoints reflected on such new Rent Supplement with respect to the Rate Base covered by such prior Rent Supplement shall be as set forth on the Percentage
Rent Schedule of such prior Rent Supplement. 
 (c) If following a Rent Supplement there is a difference in (i) the amount of actual
Incremental CapEx compared to the amount contemplated by the then-effective Rent Supplement, (ii) the amount of actual Lessee CapEx compared to the amount contemplated by the then-effective Rent Supplement, or (iii) the placed-in-service
date of such Incremental CapEx or Lessee CapEx compared to what was contemplated at the time of the then-effective Rent Supplement, then, at any time within two years of the date the Parties agree to a Rent Supplement, either Party may request a
Rent Validation. If there has been such a difference, the 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 9 

 
Parties will supplement Incremental CapEx, Base Rent, Percentage Rent Percentages, Annual Percentage Rent Breakpoints, Revenues Attributable to Lessee CapEx and/or Lessee CapEx, as applicable, to
what they would have been, at the time of the Rent Supplement, to reflect (1) the amount of actual Incremental CapEx and Lessee CapEx and/or (2) the actual dates such Incremental CapEx and/or Lessee CapEx was placed in service, but keeping
fixed all other relevant assumptions and inputs, including the Comparable Rate of Return. For the avoidance of doubt, in no circumstance will a Rent Validation occur to account for any difference between the initially anticipated and the actual
return of or on the Incremental CapEx and/or Lessee CapEx, and no such difference will be taken into account as part of such Rent Validation. The Parties also will negotiate in good faith to determine (A) whether one Party should make a lump
sum payment to the other Party as a result of excess or deficient Rent Lessee paid, prior to the date of the effective date of the Rent Validation, in connection with the Rent Supplement, and, (B) if applicable, the amount of any such lump sum
payment. The Parties will memorialize the result of any Rent Validation negotiation by executing and delivering a revised Rent Supplement, which will set forth revised expected Incremental CapEx, Lessee CapEx, Base Rent, Percentage Rent Percentages,
Annual Percentage Rent Breakpoints and/or Revenues Attributable to Lessee CapEx, as applicable, the effective date on which such changes will occur and, if applicable, the amount of the lump sum payment that one Party must make to the other Party
(which payment must be made within 30 days of the execution and delivery of such revised Rent Supplement). Any lump sum payments received by Lessor under this Section 3.2(c) shall be treated as Rent by the Parties. Upon execution and delivery
of any such Rent Validation, this Agreement will be deemed amended thereby. The Parties will reasonably cooperate to minimize the number of Rent Validations, and prospective Rent Supplements and Rent Validations may be combined into one revised,
amended and restated Rent Supplement. 
 (d) In connection with the foregoing provisions of this Section 3.2, Lessor and Lessee shall
use good faith efforts to agree to a Rent Supplement, renewal of a Rent Supplement or Rent Validation, as applicable, within 60 days of a request therefor by either Party. If, by the end of such 60 day period, Lessee and Lessor cannot in good faith
agree to the terms of a Rent Supplement, renewal of a Rent Supplement or Rent Validation, such dispute shall be submitted to arbitration in accordance with Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be
empowered to determine the terms of such Rent Supplement, renewal of a Rent Supplement or Rent Validation (including any lump sum payment amount), based on submissions by each of the Lessee and the Lessor. 

3.3 Confirmation of Percentage Rent. 

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

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 10 

 (b) Lessee shall utilize, or cause to be utilized, an accounting system for the CREZ Assets in
accordance with the FERC Uniform System of Accounts for electric utilities, that will accurately record all data necessary to compute Percentage Rent, and Lessee shall retain and shall allow Lessor and its representatives to have reasonable access
to, for at least five (5) years after the expiration of each Lease Year, reasonably adequate records conforming to such accounting system showing all data necessary to conduct Lessor’s Audit and to compute Percentage Rent for the
applicable Lease Years and to otherwise file or defend tax returns and reports to any Regulatory Authority. 
 (c) Lessor shall have the
right from time to time to cause its accountants or representatives to conduct an inspection, examination and/or audit (a “Lessor’s Audit”) of all of Lessee’s records, including supporting data, sales and excise tax
returns and the records described in Section 3.3(b), reasonably required to complete such Lessor’s Audit and to verify Percentage Rent, subject to any prohibitions or limitations on disclosure of any such data under applicable laws,
regulations and governmental requirements. If any Lessor’s Audit discloses a deficiency in the payment of Percentage Rent, and either Lessee agrees with the result of Lessor’s Audit or the matter is otherwise determined or compromised,
Lessee shall forthwith pay to Lessor the amount of the deficiency, as finally agreed or determined, together with interest at the Overdue Rate from the date when said payment should have been made to the date of payment thereof. In addition to the
amounts described above in this Section 3.3(c), if any Lessor’s Audit discloses a deficiency in the payment of Percentage Rent which, as finally agreed or determined, exceeds 3% of the amount paid, Lessee shall pay the costs of
Lessor’s Audit. In no event shall Lessor undertake a Lessor’s Audit after March 31 of the second year following the Lease Year for which such audit is requested. 

(d) Any proprietary information obtained by Lessor pursuant to the provisions of this Section 3.3 shall be treated as confidential, except
that such information may be used, subject to appropriate confidentiality safeguards, in any litigation or arbitration between the Parties and except further that Lessor may disclose such information to lenders and investors, including prospective
lenders or investors and to any other persons to whom disclosure is necessary or appropriate to comply with applicable laws, regulations and governmental requirements and to comply with any reporting requirements applicable to Lessor or Lessee under
any applicable securities laws or regulations or any listing requirements of any applicable securities exchange. 
 (e) The obligations of
Lessee and Lessor contained in this Section 3.3 shall survive the expiration or earlier termination of this Agreement. Any dispute as to the existence or amount of any deficiency in the payment of Percentage Rent as disclosed by Lessor’s
Audit shall, if not otherwise settled by the Parties, be submitted to arbitration pursuant to the provisions of Section 13.7. 

  
 CREZ
ASSETS LEASE AGREEMENT

 3.4 Additional Rent. In addition to Base Rent and Percentage
Rent, Lessee also will pay and discharge as and when due and payable all other amounts, liabilities, obligations and impositions that Lessee assumes or agrees to pay under this Agreement, including without limitation, the expenses described in
Section 1.3 and any reimbursement for such amounts and other damages to Lessor in the event that Lessor pays such expenses or performs such obligations on behalf of Lessee (collectively, “Additional
Rent”). 
 3.5 No Set Off. Rent shall be paid to Lessor without set off, deduction
or counterclaim; provided, however, that Lessee shall have the right to assert any claim or counterclaim in a separate action brought by Lessee under this Agreement or to assert any mandatory counterclaim in any action brought by Lessor under this
Agreement. 
 3.6 Late Payment Penalty. If Lessee fails to make any payment of Rent to Lessor within five
(5) days after it is due, interest shall accrue on the overdue amount, from the date overdue until the date paid, at the Overdue Rate. 

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

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

ARTICLE IV 

LESSEE’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

Lessee hereby represents, warrants and covenants to Lessor that: 

4.1 Maintenance, Operation and Repair of the CREZ Assets. 

(a) Lessee, at its own cost and expense, shall maintain (including both scheduled and unscheduled maintenance), operate, repair and make all
modifications (other than Footprint Projects) to the CREZ 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 CREZ Assets, in
each case, as reasonable and prudent and consistent with Good Utility Practice and as required by Applicable Law. Lessee shall carry out all obligations under this Agreement as reasonable and prudent and consistent with Good Utility Practice and in
accordance with manufacturers’ warranty requirements (during any applicable warranty 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 12 

 
period) and the Lessee’s established operating procedures and maintenance, rebuild and repair programs so as to keep the CREZ 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 CREZ Assets in a reliable and safe manner in compliance with all applicable requirements and regulations of Regulatory Authorities.
Lessee will not operate the CREZ 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 CREZ Assets by Lessor show that the CREZ 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
CREZ Assets can be modified to comply with the standards, and (ii) complete any and all such modifications consistent with all applicable reliability and safety standards established by regulations, orders or requirements of Regulatory
Authorities. 
 4.2 Licenses and Permits. Lessee shall obtain and maintain any and all licenses, permits
and other governmental and third-party consents and approvals required by Applicable Law in order to carry out its obligations under this Agreement. 

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

4.4 Requirements of Governmental Agencies and Regulatory Authorities. Lessee, at its expense, shall comply
with all Applicable Laws, including without limitation all requirements of the Regulatory Authorities. Lessee shall have the right, in its reasonable discretion and at its cost and expense, to contest by appropriate legal proceedings, the validity
or applicability to the CREZ Assets of any Applicable Law made or issued by any federal, state, county, local or other 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 13 

 
governmental agency or entity. Any such contest or proceeding shall be controlled and directed by Lessee. Notwithstanding the foregoing, Lessee shall provide Lessor written notice of the
commencement and, at reasonable intervals after commencement, the progress of any such legal proceedings. 
 4.5
Liens. Lessee shall keep the CREZ Assets free and clear of all Liens other than Permitted Liens; provided, however, that if Lessee wishes to contest any such Lien (other than a Permitted Lien), Lessee shall, promptly,
and in any event within thirty (30) days after it receives notice of the filing of such Lien, remove or bond over such lien from the CREZ Assets pursuant to Applicable Law. If Lessee fails to promptly remove or bond over any such Lien, Lessor
may, after providing notice to Lessee, take reasonable action to satisfy, defend, settle or otherwise remove the Lien at Lessee’s expense. 

4.6 Hazardous Materials. 

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

(b) Without limiting the generality of the foregoing, Lessee shall not (i) place or locate any underground tanks on the property
underlying the CREZ Assets, (ii) generate, manufacture, transport, produce, use, treat, store, release, dispose of or otherwise deposit Hazardous Materials in or on the CREZ Assets, the property underlying the CREZ Assets or any portion thereof
other than as permitted by Applicable Laws that govern the same or are applicable thereto, (iii) permit any other substances, materials or conditions in, on or emanating from the CREZ Assets, the property underlying the CREZ 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 CREZ
Assets. 
 (c) Lessee shall periodically, at intervals determined in its reasonable discretion in accordance with Good Utility Practice or as
required by Applicable Law, at Lessee’s sole expense, conduct inspections of all components of the CREZ Assets to ensure compliance with Applicable Laws and with this Section 4.6, and shall promptly notify Lessor of the results of any such
inspections. Lessor may, at Lessor’s expense, conduct its own testing at times determined in its reasonable discretion, and after reasonable consultation with Lessee, to ensure Lessee’s compliance with Applicable Laws and with this
Section 4.6, provided, however, that Lessor agrees to indemnify Lessee, in accordance with Section 12.2, from and against any and all Claims arising from such testing. 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 14 

 4.7 Indebtedness. Lessee shall not incur Indebtedness other
than: (i) Indebtedness in an aggregate principal amount of up to the greater of (A) $5,000,000 and (B) an amount equal to one percent (1%) of the sum of, without duplication, (x) the total amount of the Consolidated Net
Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee, plus (z) the total amount of Leased Consolidated Net Plant of
Lessee, in each case on a senior secured basis, (ii) Indebtedness in an aggregate principal amount of up to the greater of (A) $10,000,000 and (B) an amount equal to one-and-a-half percent (1.5%) of the sum of, without
duplication, (x) the total amount of the Consolidated Net Plant of Lessee, plus (y) the total amount of the Consolidated Net Plant of any guarantor(s) of Lessee’s obligations under any Lease to which Lessee is a party as a lessee,
plus (z) the total amount of Leased Consolidated Net Plant of Lessee, in each case on an unsecured subordinated basis on terms substantially similar to the terms set forth on Exhibit 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, any of Lessee’s subsidiaries may incur Indebtedness in an aggregate principal amount of up to the product of
(x) Lessee’s aggregate Consolidated Net Plant multiplied by (y) the lesser of (A) the sum of Lessee’s then-current PUCT-regulated debt-to-equity ratio (expressed as a percentage) and five percent (5%) or
(B) sixty-five percent (65%); provided, however, that such Indebtedness must be Non-Recourse Debt to Lessee. For purposes of this Section 4.7, Lessee’s Consolidated Net Plant will be derived from its most recently prepared
consolidated balance sheet, prepared in accordance with GAAP but adjusted to reverse the effects of failed sale-leaseback accounting in a manner reasonably determined by Lessee in good faith. Without limiting the amount of Indebtedness permitted by
the foregoing, Lessee may also incur Indebtedness (x) in the form of a pledge of equity interests in a subsidiary of Lessee as security for Non-Recourse Debt of such subsidiary and (y) in amounts otherwise permitted under the SDTS Debt
Agreements. 
 4.8 Records. In addition to the records referred to in Section 3.3, Lessee shall maintain proper
books of record and account in conformity with GAAP and all applicable Regulatory Authorities and each other governmental agency or authority having legal or regulatory jurisdiction over Lessee. Additionally, Lessee shall maintain or cause to be
maintained all logs, drawings, manuals, specifications and data and inspection, modification and maintenance records and other materials required to be maintained in respect of the CREZ Assets by Applicable Laws or by prudent and Good Utility
Practice. Lessee shall allow Lessor and its representatives to have reasonable access to, for at least five (5) years after the expiration of each Lease Year, the records referred to in this Section 4.8. 

4.9 Surrender. Upon expiration or earlier termination of this Agreement in accordance with its terms (but subject to
Section 2.2 and the requirements of all Applicable Laws), and in a manner calculated to avoid any disruption of electrical service, Lessee shall vacate and surrender possession of all components of the CREZ Assets (other than in respect of
Footprint Projects funded by Lessee as described in Section 10.5(a)) to Lessor, or to such other person or entity as Lessor may direct. At the time of such surrender, the CREZ Assets shall be free and clear of Liens and other rights of third
parties (other than Permitted Liens), and shall be in the same condition as the date the construction of such CREZ Assets 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 15 

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

4.10 Cooperation; Transition Services. 

(a) During the period after notice of termination and prior to the termination of the Agreement, with reasonable notice, Lessee will cooperate
in all reasonable respects with the efforts of Lessor to sell or lease the CREZ Assets (or any component thereof) or any interest therein, including, without limitation, permitting prospective purchasers or lessees to fully inspect the CREZ 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 CREZ Assets or cause Lessee to incur any additional
expenses other than as specifically provided herein. All information obtained in connection with such inspection shall be subject to confidentiality requirements at least as restrictive as those contained in Section 13.3. 

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

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

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

  
 CREZ
ASSETS LEASE AGREEMENT

 4.13 Financing. Lessee acknowledges that Lessor has obtained
financing secured by, among other things, the CREZ Assets and this Agreement. In connection with such financing, Lessor made certain representations, warranties and covenants set forth in that certain Credit Agreement a copy of which has been
provided to and reviewed by Lessee. Lessee hereby agrees with Lessor that, to the extent not otherwise covered by the terms of this Agreement, Lessee hereby makes the same representations and warranties to Lessor as Lessor makes to the Financing
Parties (as defined in the Credit Agreement) in Sections 5.4 (Financial Statements; Material Adverse Effect), 5.5 (Disclosure), 5.6 (No Material Adverse
Effect), 5.7 (Governmental Approvals), 5.9 (Taxes), 5.10 (Title to Properties; Eminent Domain Authority; Possession Under Leases;
Investments), 5.11 (Security Documents), 5.12 (Filings), 5.13 (Investment Company), 5.14 (Governmental
Regulation), 5.16 (Compliance with Legal Requirements), 5.17 (OFAC), 5.18 (PUCT; ERCOT), 5.19
(Permits), 5.20 (Litigation), 5.21 (No Default), 5.22 (Insurance), 5.23 (Certain

(Partnerships and Joint Ventures; Separateness), 5.28 (Accounts), and 5.29 (Solvency) of the Credit Agreement to the extent that such
representations and warranties relate to Lessee, whether in its capacity as Lessee or otherwise, including, without limitation, Lessee’s status or operations as a public utility, and (ii) Lessee hereby covenants and agrees with Lessor
that, during the term of the Credit Agreement, Lessee will comply with the covenants set forth in Sections 6.10 (Material Project Documents) (to the extent that Lessee is a party to any Material Project Documents),
6.12 (Operation of Project), 6.13 (PUCT; ERCOT), 6.19 (Construction of Project), 7.9 (Material Project
Documents) and 7.10 (Amendments to Organizational Documents) of the Credit Agreement. 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 the Lessee, directly or indirectly, in a manner that would result in a Change of Control of Lessee. The Parties agree to
amend, alter or supplement this Section 4.13 from time to time to give effect to the obligations under Lessor’s then-current credit arrangements. 

ARTICLE V 
 LESSOR’S
REPRESENTATIONS, WARRANTIES AND COVENANTS 
 Lessor hereby represents, warrants and covenants as follow: 

5.1 Lessor’s Authority. 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. This Agreement constitutes the legally valid and binding obligation of Lessor, enforceable against Lessor in accordance with its terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar Applicable Laws affecting the enforcement of creditors’ rights generally and equitable principles. 

5.2 Liens and Tenants. Lessor represents that Lessor has good and valid title to the CREZ Assets, there are no unrecorded
liens, encumbrances, leases, mortgages, deeds of trust (except as disclosed to Lessee in writing or as arise by operation of law), or other exceptions (collectively, “Liens”) arising as a result of any acts or omissions to act of
Lessor by, through or under Lessor to Lessor’s right, title or interest in the CREZ Assets other than any such of the foregoing that does not materially impair the Lessee’s use of the CREZ Assets, and, to Lessor’s knowledge, there
exist no rights or interests of any third party relating to the 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 17 

 CREZ Assets that are not contemplated herein. Except for Permitted Liens or as may be disclosed in the applicable
real property records in the State of Texas, or as disclosed by Lessor in writing to Lessee, Lessor represents that there are no mortgages, deeds of trust, or similar liens or security interests encumbering all or any portion of the CREZ Assets.
Lessor shall fully cooperate and assist Lessee, at no out-of-pocket expense to Lessor, in obtaining a subordination and non-disturbance agreement from each party that holds a Lien that might reasonably be expected to interfere in any material
respect with Lessee’s rights under this Agreement. Notwithstanding the foregoing, Lessor and its affiliates shall have the right to incur Permitted Liens encumbering the CREZ 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 CREZ 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 the Lessor may reasonably request. 
 5.3 Condition of Assets. Lessor
has not taken any action or failed to take any action that would cause the CREZ 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 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 required for the maintenance or operation of the CREZ Assets, including execution of applications for such
approvals, and including participating in any appeals or regulatory proceedings respecting the CREZ Assets at Lessee’s cost and expense, if requested by Lessee. 

5.5 Hazardous Materials. Lessor shall conduct its activities in respect of the CREZ Assets in compliance in all material
respects with applicable Environmental Laws. 
 5.6 Litigation. If Lessor 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 CREZ Assets, Lessor shall promptly deliver notice thereof to Lessee. 

5.7 Limitation. EXCEPT AS EXPRESSLY REPRESENTED OTHERWISE IN THIS ARTICLE V, LESSOR (A) MAKES NO AND EXPRESSLY
DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO (I) TITLE TO THE CREZ ASSETS OR ANY PORTION THEREOF, (II) ANY ESTIMATES OF THE VALUE OF THE CREZ ASSETS OR FUTURE REVENUES THAT MIGHT BE GENERATED BY THE CREZ ASSETS, (III) THE
MAINTENANCE, REPAIR, CONDITION, QUALITY, SUITABILITY, DESIGN OR MARKETABILITY OF THE CREZ ASSETS, (IV) INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHT OR (V) ANY OTHER MATERIALS OR INFORMATION THAT MAY HAVE BEEN MADE AVAILABLE OR COMMUNICATED
TO LESSEE OR ITS AFFILIATES, OR ITS OR THEIR EMPLOYEES, AGENTS, CONSULTANTS, REPRESENTATIVES OR ADVISORS IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY DISCUSSION OR PRESENTATION RELATING THERETO, AND (B) FURTHER
DISCLAIMS ANY REPRESENTATION OR WARRANTY, 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 18 

 
EXPRESS OR IMPLIED, OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS OF ANY PORTION OF THE CREZ ASSETS, IT BEING EXPRESSLY UNDERSTOOD AND
AGREED BY THE PARTIES HERETO THAT THE CREZ 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 CREZ Assets. 

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

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

(c) If such repair or replacement constitutes a Footprint Project, then, as long as the related costs have been included in a CapEx Budget, the
cost of repairing or replacing such damage or loss, whether actually covered in whole or in part by insurance, shall be the responsibility of Lessor. In such circumstance, unless otherwise agreed by the Parties, (i) if the damage or loss is
covered by insurance, Lessor shall be responsible for payment of any deductible, and (ii) any damage or loss not covered by insurance (exclusive of any deductible) shall be the responsibility of Lessor. If the sum of such deductible and
insurance proceeds exceeds the cost of such Footprint Project, then such excess will first reduce Lessor’s obligation to fund the deductible hereunder, and any excess thereafter will be retained by Lessee. If such repair or replacement
constitutes a Footprint Project that is not included in a CapEx Budget, the provisions of Article X shall apply. 
 (d) Lessee shall be
solely responsible for all costs of repairing or replacing any damaged property and equipment that is not part of the CREZ Assets and owned by Lessee, whether covered by Lessee’s insurance under Section 6.2 or otherwise. Nothing in this
provision shall preclude Lessee from seeking recovery of such costs in a rate proceeding at the PUCT. 
 (e) If Lessor funds Lessee’s
Personal Property pursuant to Section 10.1(b) of this Agreement, then all such funded Personal Property will be treated as a Footprint Project, and not a Repair, for purposes of this Section 6.1. 

  
 CREZ
ASSETS LEASE AGREEMENT

 6.2 Insurance. Lessee will maintain, with financially sound and reputable
insurers, insurance with respect to its properties and business against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and
self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated,
but in no event less than the insurance set forth in this Section 6.2 and Exhibit B. 
 (a) Lessee shall procure at its own
expense and maintain in full force and effect at all times throughout the term of this insurance policies with insurance companies rated A-, 9 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 B due to (i) new information not previously known by Lessor prior to the date of this Agreement or (ii) changed circumstances after the date of this Agreement, which in the reasonable judgment of Lessor either renders a
required coverage to be materially inadequate or materially reduces the financial ability of the approved insurance companies to pay claims. 

(c) On the first Business Day of each year, if so requested by Lessor, Lessee shall furnish Lessor with certification of all required
insurance. Such certification shall be executed by each insurer or by an authorized representative of each insurer where it is not practical for such insurer to execute the certificate itself. Such certification shall identify underwriters, the type
of insurance, the insurance limits, and the policy term, and shall specifically list the special provisions enumerated for such insurance required by this Section 6.2. Upon request, Lessee will promptly furnish Lessor with copies of all
insurance certificates, binders, and cover notes or other evidence of such insurance relating to the CREZ Assets. 
 (d) Concurrently with
the furnishing of the certification referred to in Section 6.2(c) and on an annual basis thereafter, Lessee shall furnish Lessor with a certificate, signed by an officer of Lessee, stating that all premiums then due have been paid and that the
insurance then carried or to be renewed is in accordance with the terms of this Section 6.2. and Exhibit B. 
 (e) In the event Lessee
fails to take out or maintain the full insurance coverage required by this Section 6.2 and Exhibit B, Lessor, upon thirty (30) days’ prior notice (unless the aforementioned insurance would lapse within such period, in which
event notice should be given as soon as reasonably possible) to Lessee of any such failure, may (but shall not be obligated to) take out the required policies of insurance and pay the premiums on the same. All amounts so advanced thereof by Lessor
shall become an additional obligation of Lessee to Lessor, and Lessee shall forthwith pay such amounts to Lessor. 
 (f) No provision of this
Section 6.2 or Exhibit B or any other provision of this Agreement, shall impose on Lessor any duty or obligation to verify the existence or adequacy of the insurance coverage maintained by Lessee, nor shall Lessor be responsible for any
representations or warranties made by or on behalf of Lessee to any insurance company or underwriter. 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 20 

 (g) Notwithstanding the foregoing, the Parties acknowledge that Lessee has not been able to
obtain property insurance on commercially reasonable terms to comply with Exhibit B, and as a result Lessor has waived and, until such time as Lessee can obtain such coverages on commercially reasonable terms, hereby does waive the
requirements of Exhibit B in favor of the property insurance coverages that have been obtained and are currently in effect; provided that Lessor has obtained a waiver of this insurance requirement under the Credit Agreement. 

ARTICLE VII 
 REPORTING

 7.1 Private Financing Arrangements. Lessee understands that Lessor, or an affiliate thereof, has
raised equity and debt capital secured by the CREZ Assets and this Agreement and that Lessor or its affiliates have reporting obligations in connection with such arrangements, including obligations to provide financial statements prepared in
accordance with GAAP, to prepare an annual strategic plan and to update such annual strategic plan in the event of certain material deviations therefrom. Lessee understands that Lessor relies on Lessee in order to comply with such obligations. From
time to time, Lessor or an affiliate thereof may enter into additional arrangements that impose similar obligations. Accordingly, Lessee agrees to provide Lessor in a timely manner audited year-end financial statements, quarterly unaudited financial
statements for the first three quarters of each year (certified by a financial officer of Lessee), estimates of Percentage Rent, and such acknowledgements, certificates, permits, licenses, instruments, documents and other information as Lessor may
reasonably request from time to time in connection with, or to enable Lessor and its affiliates to comply with any such debt or equity financing arrangements or with Applicable Law. The Parties will negotiate in good faith the time frames during
which Lessee will provide such information, with the intention that Lessee provide such information in a manner that is not unduly burdensome but that also allows Lessor sufficient time to comply with its reporting obligations. Lessee will also
cooperate with Lessor to enable Lessor to satisfy its obligations in respect of annual strategic plans, including providing Lessor with requested information in advance of the due date of such annual strategic plan and keeping Lessor apprised of
deviations in capital expenditures, construction activity or revenues of Lessee from amounts that were originally provided by Lessee in preparing such annual strategic plan. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be
unable to meet the reporting requirements set forth herein in a timely manner and to reasonably cooperate with Lessor to remedy the effects of such non-compliance. 

7.2 Public Company and Regulatory Information and Cooperation. 

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

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 21 

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

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

(d) Lessee and Lessor agree to reasonably cooperate to ensure that, to the extent they require information from the other party in order to
prepare their financial statements, to obtain audits of those financial statements and, if required, of their internal control over financial reporting, to respond to comments of the Securities and Exchange Commission on such financial statements or
statements related to internal control over financial reporting or disclosure controls and procedures, or to ensure the efficacy of their internal controls or disclosure controls and procedures, they will reasonably cooperate in order to ensure that
each Party is able to meet its obligations in respect thereof. Lessee agrees to promptly notify Lessor of or provide to Lessor, as applicable, (i) any material communication, written or otherwise, submitted to the Lessee by its auditors,
including, but not limited to an audit response letter, accountant’s management letter or other written report submitted to Lessee by its accountants or any governmental agency in connection with an annual or interim audit of Lessee’s
books, (ii) any material correspondence with, reports of or reports to any Regulatory Authority with respect to the CREZ Assets and (iii) any notices of violations of Applicable Law with respect to the CREZ Assets, in each case taking into
account the REIT’s reporting obligations as a public company. 
 (e) Lessor agrees to inform Lessee of the time periods in which each of
the items identified in this Section 7.2 will be required, which may change. Lessee agrees to use reasonable efforts to advise Lessor if Lessee will be unable to meet the reporting requirements set forth herein in a timely manner and to
reasonably cooperate with Lessor to remedy the effects of such non-compliance. 
 (f) If Lessor identifies additional matters with respect to
which Lessee input, assistance or information is required in order for Lessor and its affiliates to comply with any applicable securities laws, the rules or regulations of any exchange on which the securities of such affiliate are traded or any
similar laws, rules or regulations, the Parties agree to cooperate and negotiate in good faith in order to determine the manner in which Lessee can provide such input, assistance or information in a manner that positions Lessor and its affiliates to
comply in a timely manner with such laws, rules or regulations, as efficiently as is feasible so as to minimize the burden that the provision of such input, assistance or information imposes on Lessee. 

  
 CREZ
ASSETS LEASE AGREEMENT

 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 CREZ Assets, as applicable. 
 ARTICLE VIII 

ASSIGNMENT 
 This Agreement
shall not be assignable by either Party, nor shall the CREZ Assets or any part thereof be subleased by Lessee, except with the prior written consent of the other Party and the prior approval of any Regulatory Authority whose approval is required for
the effectiveness of such assignment or sublease. For purposes of this Article VIII, an “assignment” by Lessee shall mean and include, in addition to any direct transfer by Lessee to a third party of all or any part of Lessee’s
rights, estate or interests under this Agreement, any direct or indirect, voluntary or involuntary transfer of or encumbrance on all or any part of Lessee’s rights, estate or interests under this Agreement (i) by operation of law and/or
(ii) by direct or collateral transfer of all or any part of the legal or beneficial ownership interest in Lessee by merger, consolidation or otherwise, provided, in the case of clause (ii), any such transaction or transactions will only
constitute an assignment hereunder to the extent they result in a Change of Control. Notwithstanding the foregoing, Lessor shall have the right, without Lessee’s consent but subject to obtaining regulatory approval as described in the foregoing
sentence, (a) to assign, pledge or grant a security interest in any or all of its interest in the Agreement to a lender or lenders, or a trustee acting on behalf of such lenders, in connection with a financing or refinancing in which such
interest is pledged as collateral, and Lessee agrees to enter into such acknowledgments and agreements in respect thereof as the Lessor may reasonably request and (b) to assign its interest in this Agreement to a successor owner of the CREZ
Assets. 
 ARTICLE IX

 9.1

 (a) Except

 (b) Lessee (i) is generally not
paying, or admits in writing its inability to pay, its debts as they become due, (ii) files, or consents by answer or otherwise to the filing against it of, a petition for relief or reorganization or arrangement or any other petition in

 (d) Any representation or warranty made by
Lessee herein shall prove to have been inaccurate in any material respect at the time made; 
 (e) a final judgment or judgments for the
payment of money aggregating in excess of $1,000,000 are rendered against Lessee and which judgments are not, within 60 days after entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within 60 days after the expiration
of such stay; 
 (f) Lessee shall have breached or failed to comply in any material respect with any other covenant or agreement contained
herein; or 
 (g) Notwithstanding Section 9.1(a), Lessee’s failure to pay Rent when due shall not constitute a default if
(i) such failure is due to unforeseeable circumstances arising. from a physical event beyond the control of the Lessee, including the incurrence of costs and expenditures as a result of such an event that are materially in excess of budgeted
costs and expenditures or an unforeseen material decline in electricity usage as a result of such event and (ii) such failure is cured within ninety (90) days after the date such rent was due through Lessee’s payment of the entire
amount of such unpaid Rent, plus interest thereon at a rate equal to six percent (6%) per annum or the maximum rate allowed by law, whichever is lesser, from the date such Rent was originally due until the date of payment. 

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

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

 9.4 Remedies. 

(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. 
 (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 the 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 CREZ Assets 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 event of a default shall, to the maximum extent permissible under Applicable Laws, be
deemed to be in respect of past or future Rent owing under this Agreement. 
 ARTICLE X 

CAPITAL EXPENDITURES 

10.1 Capital Expenditures Generally. 

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

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 25 

 (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 CREZ Assets. If Lessor and Lessee agree, Lessor will fund such Capital Expenditures pursuant to this Agreement, through a loan or through a separate lease. Amounts Lessor
provides pursuant to this Agreement to fund any such Personal Property will be treated in a manner similar to any amounts Lessor provides to fund Footprint Projects for purposes of Section 3.2 and elsewhere herein. Lessee will cause any such
Personal Property to be titled in Lessor’s name and will reasonably cooperate with Lessor in order to enable any secured lender of Lessor or any secured lender of an affiliate of Lessor to perfect its security interest in any such Personal
Property. In the alternative, Lessor may elect to fund such Capital Expenditures through a TRS or to loan (or cause such TRS to loan) Lessee the cash to acquire any such Personal Property in a transaction in which Lessor or a TRS may retain a
security interest in such Personal Property. In such case the Parties shall negotiate in good faith the terms under which Lessor or such TRS shall fund any such Personal Property, including the terms of any lease between Lessee and the TRS or other
financing arrangements provided by the Lessor or the TRS. 
 10.2 Capital Expenditures Funded by Lessor.
Lessor agrees to fund any Footprint Projects contained in the CapEx Budget (as revised from time to time). Lessor’s obligation to fund Footprint Projects pursuant to this Section 10.2 shall include any costs associated with such
Footprint Projects that Lessee is not allowed to recover through its PUCT-approved rates. Any Footprint Projects funded by Lessor under this Section 10.2 shall be deemed to be part of the CREZ 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 which are required in order to comply with
Applicable Law or which are required by any Regulatory Authority. Any Footprint Projects funded by Lessee under this Section 10.3 shall not be considered part of the CREZ Assets for purposes of this Agreement; provided however,
that any part of the CREZ Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the CREZ Assets and reverts to the Lessor upon termination of this Agreement without further payment from Lessor to Lessee
under Section 2.3. 
 10.4 Footprint Project Construction Activities. Lessee will either use its
personnel, or either Lessee or Lessor will contract with third parties, to construct Footprint Projects. Lessee shall be responsible for the oversight of such construction activities, regardless of whether the Footprint Project is funded by Lessor
or Lessee. Lessee’s construction activities and oversight shall be intended to ensure that such construction is performed in a manner consistent with Good Utility Practice and does not adversely affect the reliability and safety of the CREZ
Assets or the ERCOT electric grid. In connection therewith, Lessor will reimburse Lessee for all Project Management Costs that Lessee incurs in connection with constructing such Footprint Project, provided that any costs and expenses of Lessee under
this Section 10.4 must be included in any CapEx Budget submitted by Lessee under Section 10.1 or approved by Lessor to qualify for reimbursement by Lessor hereunder. 

  
 CREZ
ASSETS LEASE AGREEMENT 

  
 26 

 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 CREZ Assets that is built with CIAC funds shall be considered a leasehold improvement that is part of the CREZ Assets and shall revert to the Lessor upon termination of this Agreement without
further payment from Lessor to Lessee under Section 2.3. 
 (b) Upon the expiration or termination of this Agreement, Lessor shall have
the right (but not the obligation) to purchase, subject to required regulatory approvals, any Nonseverable Footprint Projects or Severable Footprint Projects owned by Lessee at the greater of (i) net book value plus ten percent (10%) and
(ii) the fair market value thereof as determined by mutual agreement of Lessor and Lessee. If the Parties fail to agree on the amount of the purchase price, the purchase price shall be submitted to arbitration in accordance with
Section 13.7 of this Agreement, pursuant to which the Arbitration Panel shall be empowered to determine the amount of the purchase price, based on submissions by each of the Lessee and the Lessor. Lessee shall be entitled to remove any
Severable Footprint Projects owned by Lessee upon the expiration or termination of this Agreement in the event such Severable Footprint Projects are not purchased by Lessor, subject to any required regulatory approvals. 

10.6 Asset Acquisitions. Lessee and Lessor will cooperate in good faith to ensure that all CREZ Assets are
acquired in Lessor’s name or are acquired by Lessee and subsequently transferred to Lessor. In connection therewith, Lessee agrees (a) to transfer to Lessor all previously acquired CREZ Assets, (b) that any future-acquired CREZ 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 CREZ Assets to Lessor and, if applicable, to memorialize the security interest of any
lenders under the Financing Agreements in such CREZ Assets, 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 CREZ Assets are located. 
 10.7
Reimbursements. From time to time, Lessee may enter into interconnect or similar agreements that obligate the counterparty to such agreements to reimburse Lessee for Capital Expenditures in certain circumstances. Such
reimbursement obligation may, in some circumstances, be accompanied by additional security such as parent guaranty or a letter of credit. If and to the extent that (a) Lessor funds Capital Expenditures that are used for the construction or
development pursuant to any of these interconnect agreements, and (b) Lessee becomes entitled to assert any reimbursement or other rights pursuant to any such interconnect agreements, then, unless Lessor agrees otherwise, Lessee will enforce
such reimbursement or other rights and will in turn reimburse Lessor for the amount of related Capital Expenditures that Lessor has funded pursuant hereto. Lessee further agrees to reimburse Lessor for other Capital Expenditures that Lessor has
funded pursuant to this Agreement to the extent required by the Policies and Procedures.

 ARTICLE XI 

REGULATORY COOPERATION 

11.1 Jurisdiction. The Parties recognize that (i) the CREZ Assets and the operation thereof are subject to
the jurisdiction of the PUCT and to certain reliability and safety requirements of ERCOT and TRE, and (ii) Lessee holds CCNs for operation of the CREZ Assets. The Parties agree that, as the lessee hereunder, as operator of the CREZ Assets and
as the holder of the CCNs, Lessee shall be responsible for compliance with all regulatory requirements related to the CREZ Assets, including but not limited to, taking all actions reasonably necessary or advisable to comply with such requirements;

acceptable to the Administrative Agent (which acceptance shall not be unreasonably withheld). Upon request, Lessee shall submit copies of policies to the Administrative Agent.

ASSETS LEASE AGREEMENT 

  
 Exhibit B-6 

 3. Property Loss Payable Conditions. All policies covering real or personal property
wherein the Secured Parties party to the Credit Agreement have an insurable interest shall include the interests of the Secured Parties as well as Lessor and Lessee and all such property policies shall name the Collateral Agent or its assignee as
the “sole” loss payee (on all losses exceeding $5,000,000 per occurrence and in the annual aggregate) in accordance with lenders loss payable endorsement 438 BFU or other equivalent form reasonably acceptable to the Administrative Agent.
The Administrative Agent shall have the right but not the obligation to participate with the Lessor in negotiation of claims that are expected to exceed $5,000,000 in value. 

4. General Policy Conditions. Each policy shall expressly provide that all provisions thereof, except the limits of liability (which
shall be applicable to all insureds as a group) and liability for premiums (which shall as between Lessor and Lessee, be the responsibility of Lessee) shall operate in the same manner as if there were a separate policy covering each such insured,
shall name the Administrative Agent, the Collateral Agent and the other Secured Parties as additional insured (with the exception of workers compensation) and shall waive subrogation against the Administrative Agent, the Collateral Agent and the
other Secured Parties, Lessee and Lessor and shall waive any right of the insurers to any setoff or counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of Lessor, Lessee, the Administrative Agent, the
Collateral Agent and the other Secured Parties. Each of the property and liability related policies required above (to the extent commercially available) shall provide that if any premium or installment is not paid when due, or if such insurance is
to be cancelled, terminated or reduced for any reason whatsoever, the insurers (or their representatives) will promptly notify Lessor and the Administrative Agent, and any such cancellation, termination or change shall not be effective until 60 days
after receipt of such notice by the Administrative Agent (10 days with respect to non-payment of premium), and that appropriate certification shall be made to Lessor by each insurer with respect thereto. Policies of insurance provided in accordance
with this Exhibit B shall be primary with respect to any other insurance carried by the Administrative Agent, the Collateral Agent and the other Secured Parties. 

5. Claims Conditions. In the event that Lessee or Lessor fails to respond in a timely and appropriate manner (as reasonably determined
by the Administrative Agent) to take any steps necessary or reasonably requested by the Administrative Agent to collect from any insurers for any loss covered by any insurance required to be maintained by this Exhibit B, the Lessee
acknowledges that the Administrative Agent shall have the right to make all proofs of loss, negotiate all claims and receive all or any part of the proceeds of the foregoing insurance policies, either in its own name or the name of Lessor or Lessee;
provided, however, that Lessee shall, upon the Administrative Agent’s request and at Lessee’s own cost and expense, make all proofs of loss and take all other steps necessary or reasonably requested by the Administrative Agent to collect
from insurers for any loss covered by any insurance required to be obtained by this Exhibit B.

 Exhibit B-7 

 6. Annual Certification of Compliance. At the request of Lessor, Lessee shall furnish to
Lessor and the Administrative Agent, with a copy for each Lender, as required, a certificate signed by an authorized officer of Lessee or authorized insurance representative, showing the insurance then maintained by or on behalf of Lessee pursuant
to this Exhibit B and stating that such insurance complies in all material aspects with the terms hereof, is in full force and effect and that all premiums then due have been paid or are not in arrears. In the event that at any time the
insurance as herein provided shall be reduced (and such reduction is not reinstated) or cease to be maintained, then (without limiting the rights of the Administrative Agent under the Credit Agreement in respect of the Event of Default which arises
as a result of such failure) the Administrative Agent may at its option maintain the insurance required hereby and, in such event, Lessee shall reimburse the Lessor or the Administrative Agent, as applicable, upon demand for the cost thereof
together with interest thereon at a rate as specified in the Credit Agreement, but in no event shall the rate of interest exceed the maximum rate permitted by law. 

7. Waiver of Insurance Requirements. In the event any insurance (including the limits or deductibles thereof) herein required to be
maintained, other than insurance required by law to be maintained, shall not be available and commercially feasible in the commercial insurance market, the Administrative Agent, with the advice of the Insurance Consultant, shall not unreasonably
withhold its agreement to waive such requirement to the extent the maintenance thereof is not so available; provided, however, that (i) Lessee shall first request any such waiver in writing, which request shall be accompanied by written
reports prepared by their authorized insurance representative or other insurance advisor of recognized national standing certifying that such insurance is not reasonably available and commercially feasible in the commercial insurance market for
similarly situated transmission facilities (and, in any case where the required amount is not so available, certifying as to the maximum amount which is so available) and explaining in detail the basis for such conclusions, such insurance advisers
and the form and substance of such reports to be reasonably acceptable to the Administrative Agent; (ii) at any time after the granting of any such waiver, the Lessor or the Administrative Agent may request, and Lessee shall furnish to the
Administrative Agent within 15 days after such request, supplemental reports reasonably acceptable to the Administrative Agent from such insurance advisers updating their prior reports and reaffirming such conclusion; and (iii) any such waiver
shall be effective only so long as such insurance shall not be available and commercially feasible in the commercial insurance market, it being understood that the failure of Lessee to timely furnish any such supplemental report shall be evidence
that such waiver is no longer effective because such condition no longer exists, but that such failure is not the only way to establish such non-existence. 

8. Other Insurance. The Lessor or the Administrative Agent shall have the right to make requests for additional insurance to the extent
that (i) insurance becomes available on commercially reasonable terms which had previously not been available, (ii) exposures at the Project increase necessitating an increase in limits or an additional type of insurance, all subject to
commercial availability, (iii) other operations of a similar nature sustain losses or threats of losses which could happen at any location that contains the Collateral or other physical property or assets that secure the Obligations or
(iv) such other or additional insurance (as to types of risks covered, policy amounts, deductibles and other terms and conditions) as, under prudent utility practices, are from time to time insured against for property and facilities similar in
nature, use and location to the Project.
