WHEREAS, immediately prior to the effectiveness of the Registration Statement, Hunt-InfraREIT received 1,700,000 shares of Common Stock as
payment of a structuring fee (the “Structuring Fee Shares”) and immediately transferred 75,000 of such shares to OpTrust Infrastructure N.A. Holdings Trust (the “OpT Shares”); 

WHEREAS, on the date of the closing of the Offering (the “Closing Date”), the Company will engage in certain reorganization

WHEREAS, as part of the IPO Date Transactions, Hunt-InfraREIT will redeem 1,551,878 Class A Units which the Company will satisfy through
the issuance to Hunt-InfraREIT of 1,551,878 shares of Common Stock on the IPO Closing Date (the “Redemption”); 
 WHEREAS,
as a result of the issuance by the Company of the Structuring Fee Shares, the transfer of the OpTrust Shares by Hunt-InfraREIT and the IPO Date Transactions, including the Redemption, Hunt-InfraREIT will hold (i) 3,176,878 shares of Common
Stock of the Company, (ii) 1,167,287 common units in the Operating Partnership (“Common Units”), (iii) 10,166,525 Class A units (“Class A Units”) in the Operating Partnership and (iv) 45,799,362
Class B units (“Class B Units”) in the Operating Partnership (collectively, the “IPO Date Equity”); 

WHEREAS, in accordance with the Second Amended and Restated Agreement of Limited Partnership of the Operating Partnership to become effective
on the Closing Date (the “OP Agreement”), and the Amended and Restated Charter of the Company (the “Charter”), on or around the day that is 32 days after the Closing Date, the Company and the Operating Partnership
will engage in certain reorganization transactions as a result of which, among other things, all of the Class A Units will convert into Common Units, the Class B Units will be cancelled and Hunt-InfraREIT may receive additional Common Units as
more fully described in the Registration Statement (the “Post-IPO Reorganization”); 
 WHEREAS, Hunt has informed the
Company that it intends to continue to hold substantially all of its equity, including (i) the Common Stock and Common Units it holds 

 
following the IPO Date Transactions and (ii) the Common Units Hunt-InfraREIT receives in the Post-IPO Reorganization and any shares of Common Stock it receives upon redemption thereof in
accordance with the OP Agreement (collectively, the “Post-Reorganization Equity) for the foreseeable future; and 
 WHEREAS, the
parties hereto wish to provide for certain arrangements with respect to the sale and transfer of the Post-Reorganization Equity held by Hunt-InfraREIT; 

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 AGREEMENT 

1. Restrictions. Hunt hereby agrees that, for the period described in Section 2 (the “Lock-Up Period”), it will
not, without the prior written consent of the Company (which the parties acknowledge will require the approval of at least a majority of the members of the Board of Directors not affiliated with Hunt), directly or indirectly: (i) offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer (A) any IPO Date Equity or (B) any
Post-Reorganization Equity owned by Hunt as of the consummation of the Post-IPO Reorganization (collectively, the “Lock-Up Securities”), or (ii) enter into any swap or any other agreement or any transaction that transfers, in
whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing
restrictions are expressly agreed to preclude Hunt from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of Hunt’s Lock-Up Securities even if
such Lock-Up Securities would be disposed of by someone other than Hunt. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put
or call option) with respect to any of Hunt’s Lock-Up Securities or with respect to any security that includes, relates to, or derives any significant part of its value from such Lock-Up Securities. Notwithstanding the foregoing, the
restrictions contained in this Section 1 shall not apply to (a) the IPO Date Transactions, (b) the Post-IPO Reorganization or (c) Hunt’s redemption of units of partnership interests in the Operating Partnership (“OP
Units”) for cash (or, at the election of the Company, shares of Common Stock) in accordance with the terms of the OP Agreement. For the avoidance of doubt, Lock-Up Securities shall not include any OP Units or shares of Common Stock acquired
by Hunt after the date hereof (other than as a result of the IPO Date Transactions, the Post-IPO Reorganization or the redemption of OP Units held by Hunt as of the consummation of the Post-IPO Reorganization). 

2. Lock-Up Period. For the purposes of this Agreement, the Lock-Up Period shall mean: (i) with respect to 100% of the Lock-Up
Securities, the period beginning on the date hereof and ending one year after the Closing Date; (ii) with respect to 80% of the Post-Reorganization Equity, the period beginning on the date hereof and ending three years after the Closing Date
and (iii) with respect to 50% of the Post-Reorganization Equity, the period beginning on the date hereof and ending five years after the Closing Date. The period beginning 

 
on the date hereof and ending one year after the Closing Date shall hereinafter be referred to as the “One-Year Lock-Up Period.” For the avoidance of doubt, Hunt’s
redemption of OP Units for shares of Common Stock pursuant to the OP Agreement shall not affect the timing of the commencement or the expiration of the Lock-Up Period. 

3. Permitted Transfers. Notwithstanding the foregoing, Hunt may transfer Lock-Up Securities without the prior written consent of the
Company: 
  

	 	a.	to current or former employees or service providers of Hunt who are not Hunt Group Members (as defined in the OP Agreement); provided that (x) the total number of shares or OP Units transferred to such employees or
service providers does not exceed 20% of the Post-Reorganization Equity and (y) any such transferee agrees to the One Year Lock-Up Period; and 

  

	 	b.	to Hunt Group Members; provided that such Hunt Group Member executes a joinder to this Agreement agreeing to be bound by the terms and conditions of this Agreement to the same extent as Hunt. 

4. Employees and Officers. Hunt shall take reasonable steps to ensure that, during the One Year Lock-Up Period, employees and officers
of either Hunt or its affiliates (other than employees who hold, in the aggregate, less than 50,000 shares Common Stock, after giving effect to the Post-IPO Reorganization) may not, without the prior written consent of the Company, directly or
indirectly: (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any of the equity
in the Company or the Operating Partnership held at the Closing Date, received in connection with the Offering or received from Hunt pursuant to Section 3, or (ii) enter into any swap or any other agreement or any transaction that
transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities of the Company or the Operating
Partnership, in cash or otherwise, other than transfers upon death or incapacity of the employee or officer or transfers for estate planning purposes to trusts or other vehicles, as long as, in each case, the transferee agrees to the One Year
Lock-Up Period. 
 5. Effectiveness and Termination. This Agreement shall become effective on the Closing Date. This Agreement shall
terminate, and Hunt shall be released from its obligations hereunder, upon the termination or non-renewal of the Management Agreement, dated as of the date hereof, by and among Hunt Utility Services, LLC (“Hunt-Manager”), the
Operating Partnership and the Company, other than a termination by Hunt-Manager pursuant to Section 16(c) of such Management Agreement or a termination for cause pursuant to Section 18 thereof. 

 6. Notices. All notices, offers or other communications required or permitted to be given
pursuant to this Agreement shall be in writing and may be personally served, sent via facsimile, sent via electronic mail or sent by United States mail or by commercial courier and shall be deemed to have been given when received at the address set

Company does business such business must be conducted under another name. In such a case, the business of the Company in such jurisdiction may be conducted under such other name or names (except the name of the TDC Member or any Person or Entity
that is a member of the TDC Member or that is otherwise associated with the TDC Member) as the Sharyland Member shall determine to be necessary. The Sharyland Member shall cause to be filed on behalf of the Company such assumed or fictitious name

Company (other than a de minimis interest) as consideration for the provision of services 

  
 15 

 
to or for the benefit of the Company by an existing Member acting in a Member capacity, or by a new Member acting in a Member capacity in anticipation of being a Member, provided, however, that
adjustments pursuant to clauses (a), (b) and (d) above shall be made only if the Sharyland Member determines that such adjustments are necessary or appropriate to reflect the relative economic interests of the Members in the Company. 

(iii) In accordance with Regulations Section 1.704-l(b)(2)(iv)(e), the Carrying Value of Company assets distributed in
kind shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as of the time any such asset is distributed. 

(iv) In determining Unrealized Gain or Unrealized Loss for purposes of this Section 3.4, the aggregate cash amount
and fair market value of all Company assets (including cash or cash equivalents) shall be determined by the Sharyland Member using such reasonable method of valuation as it may adopt, or in the case of a liquidating distribution pursuant to
Article XIII, shall be determined and allocated by the Liquidating Trustee using such reasonable methods of valuation as it may adopt. The Sharyland Member, or the Liquidating Trustee, as the case may be, shall allocate such aggregate fair
market value among the assets of the Company in such manner as it determines in its sole and absolute discretion to arrive at a fair market value for individual properties. 

(g) The provisions of the Agreement (including this Section 3.4) relating to the maintenance of Capital Accounts are intended to
comply with Regulations Section 1.704- l(b), and shall be interpreted and applied in a manner consistent with such Regulations. In the event the Sharyland Member shall determine that it is prudent to modify the manner in which the Capital
Accounts, or any debits or credits thereto (including, without limitation, debits or credits relating to liabilities which are secured by contributed or distributed property or which are assumed by the Company, the Sharyland Member, or the TDC
Member) are computed in order to comply with such Regulations, the Sharyland Member may make such modification without regard to Section 14.4, provided that it is not likely to have a material effect on the amounts distributable to any
Person pursuant to Article XIII upon an event requiring winding up of the Company. The Sharyland Member also shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the
Members and the amount of Company capital reflected on the Company’s balance sheet, as computed for book purposes, in accordance with Regulations Section 1.704-l(b)(2)(iv)(q), and (ii) make any appropriate modifications in the event
unanticipated events might otherwise cause this Agreement not to comply with Regulations Section 1.704-1(b). 
 ARTICLE IV. 

ALLOCATIONS OF NET PROFIT AND NET LOSS; DISTRIBUTIONS 

Section 4.1 Allocations of Net Profit and Net Loss. 

(a) Except as otherwise provided in this Article IV, for any allocation period in which the Company has Net Profit or Net Loss, such Net
Profit or Net Loss (and any item of income, gain, loss or deduction thereof) shall be allocated to the Members in a manner such that, as nearly as possible, immediately after such allocation each Member has a positive balance in its

  
 16 

 
Capital Account equal to the amount such Member would be entitled to receive if the Company were liquidated as of such date, its affairs wound up and its assets distributed to the Members
pursuant to Section 4.2, taking into account the Member’s share of Company Minimum Gain and Member Nonrecourse Debt Minimum Gain before the hypothetical liquidation. Prior to the liquidation of the Company, the assets of the Company
on any date shall be deemed to have a value equal to their Carrying Value. 
 (b) Allocation of Nonrecourse Debt. For purposes of Regulation
Section 1.752-3(a), the Members agree that Nonrecourse Liabilities of the Company in excess of the sum of (i) the amount of Company Minimum Gain and (ii) the total amount of Nonrecourse Built-in Gain shall be allocated 100% to the TDC
Member. 
 (c) Recapture Income. Any gain allocated to the Members upon the sale or other taxable disposition of any Company asset shall, to
the extent reasonably practicable after taking into account other required allocations of gain pursuant to Sections 4.6 and 4.7, be characterized as Recapture Income in the same proportions and to the same extent as such Members have
been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income. 
 Section 4.2
Distributions of Available Cash. Periodically, but not less frequently than quarterly, Available Cash (if any) shall be distributed among the Members in accordance with the provisions of this Section 4.2. For any period, funds
that would otherwise constitute Available Cash need not be so treated and distributed to the extent that such funds are required for, set aside and retained in the Working Capital Reserve, the amount of such reserve to be determined, with the
Approval of the TDC Member (which Approval shall not be unreasonably withheld), by the Sharyland Member using reasonable business judgment. The purpose of the establishment and maintenance of the Working Capital Reserve is to avoid a depletion of
the Company’s money resources to be used for operations or working capital, but not for capital expenditures with respect to Footprint Projects (other than with respect to any capital expenditure for any Footprint Projects either
(i) required by Regulatory Authorities or (ii) reasonably necessary to satisfy Sharyland Utilities’ or another lessee’s obligation as a regulated utility to serve its customers or to maintain the safety or reliability of a
System) (“Working Capital Reserve for Required Footprint Projects”). The establishment or maintenance of the Working Capital Reserve is not intended to and will not alter or diminish the rights of the Members to Available Cash
except if such funds are retained and used for the purpose for which they were reserved. When and to the extent the Sharyland Member, with the Approval of the TDC Member (which Approval shall not be unreasonably withheld), no longer regards funds
set aside and retained in the Working Capital Reserve as reasonably necessary to the efficient conduct of the affairs of the Company, such funds shall be treated as additions to Available Cash. 

(a) For each Fiscal Year, Available Cash which is to be distributed among the Members pursuant to this Section 4.2 shall be
distributed among the Members as follows and in the following order of priority: 
 (i) First: Available Cash shall be
distributed one hundred percent (100%) to the TDC Member to the least extent necessary to cause the TDC Member’s Unpaid Preference Amount to equal zero (0); 

  
 17 

 (ii) Second: Available Cash shall be distributed one hundred percent
(100%) to the TDC Member to the least extent necessary to cause the TDC Member’s Unreturned Cash Capital Amount to equal zero (0); and 

(iii) Third: All remaining Available Cash shall be distributed among both of the Members, pro rata in accordance with
their respective Post-Payout Percentages. 
 Section 4.3 Distributions of Net Proceeds from a Capital Transaction. Promptly
following the collection of the Net Proceeds of a Capital Transaction and after payment of the Company’s debts and liabilities and the expenses of such Capital Transaction and/or the establishment of a reasonable reserve for the Company’s
debts and liabilities (contingent or otherwise) if deemed necessary by the Sharyland Member, the amount of all such proceeds and cash held by the Company shall be distributed to each of the Members as follows and in the following order of priority:

 (a) First: Proceeds shall be distributed one hundred percent (100%) to the TDC Member to the least extent necessary to cause
the TDC Member’s Unpaid Preference Amount to equal zero (0); 
 (b) Second: Proceeds shall be distributed one hundred percent
(100%) to the TDC Member to the least extent necessary to cause the TDC Member’s Unreturned Cash Capital Amount to equal zero (0); and 

(c) Third: All remaining Proceeds shall be distributed to both of the Members, pro rata in accordance with their respective Capital
Transaction Post-Payout Percentages. 
 Section 4.4 In Kind Distributions. Assets of the Company (other than cash) shall not be
distributed in kind to either Member unless Approved by the Members. If any assets of the Company are distributed among the Members in kind, such assets shall be valued on the basis of the fair market value thereof on the date of the distribution,
and each distributee shall receive such distribution in kind in lieu of distributions of cash. The fair market value of such assets shall be determined by an independent appraiser Approved by the Members. 

Section 4.5 Tax Distributions. Unless otherwise Approved by the TDC Member, the Sharyland Member shall cause the Company to
distribute from its funds to each Member with respect to each Taxable Year (within 60 days after the close of such Taxable Year, or on a quarterly or more frequent basis) an amount of cash equal to the taxable income of the Company allocated to such
Member with respect to such Taxable Year. Any distribution to a Member pursuant to this Section 4.5 shall be treated as an advance distribution under the appropriate provisions of Section 4.2 or 4.3 that resulted in
the allocation of income pursuant to Section 4.1 to which such distribution relates. 

  
 18 

 Section 4.6 Special Allocation Rules. Notwithstanding any other provision of this
Agreement, the following special allocations shall be made in the following order: 
 (a) Minimum Gain Chargeback. Notwithstanding the
provisions of Section 4.1 or any other provisions of this Section 4.6 or Section 4.7, if there is a net decrease in Company Minimum Gain during any Fiscal Year, each Member shall be specially allocated items of
Company income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, as determined under Regulations Section 1.704-2(g). Allocations pursuant to
the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. 
 The
items to be so allocated shall be determined in accordance with Regulations Section 1.704-2(f)(6). This Section 4.6(a) is intended to comply with the minimum gain chargeback requirements in Regulations Section 1.704-2(f) and
for purposes of this Section 4.6(a) only, each Member’s Adjusted Capital Account Deficit shall be determined prior to any other allocations pursuant to Article IV of this Agreement with respect to such Fiscal Year. 

(b) Member Minimum Gain Chargeback. Notwithstanding any other provision of Section 4.1 of this Agreement or any other
provisions of this Section 4.6 or Section 4.7 (except Section 4.6(a) hereof), if there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any Fiscal Year,
each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain
for such year (and, if necessary, subsequent years) in an amount equal to such Member’s share of the net decrease in Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5). Allocations pursuant to the
previous sentence shall be made in proportion to the respective amounts required to be allocated to each Sharyland Member and TDC Member pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations
Section 1.704-2(i)(4). This Section 4.6(b) is intended to comply with the minimum gain chargeback requirement in such Section of the Regulations and shall be interpreted consistently therewith. Solely for purposes of this
Section 4.6(b), each Member’s Adjusted Capital Account Deficit shall be determined prior to any other allocations pursuant to Article IV with respect to such Fiscal Year, other than allocations pursuant to
Section 4.6(b) hereof. 
 (c) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments,
allocations or distributions described in Regulations Sections 1.704- l(b)(2)(ii)(d)(4), 1.704-l(b)(2)(ii)(d)(5), or 1.704-l(b)(2)(ii)(d)(6), and after giving effect to the allocations required under Sections 4.6(a) and 4.6(b) hereof
with respect to such Fiscal Year, such Member has an Adjusted Capital Account Deficit, items of Company income and gain (consisting of a pro rata portion of each item of Company income, including gross income and gain for the Fiscal Year) shall be
specifically allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, its Adjusted Capital Account Deficit created by such adjustments, allocations or distributions as quickly as possible.
This Section 4.6(c) is intended to constitute a “qualified income offset” under Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. 

(d) Gross Income Allocation. In the event that any Member has an Adjusted Capital Account Deficit at the end of any Fiscal Year (after
taking into account allocations to be made under the preceding paragraphs hereof with respect to such Fiscal Year), each such Member shall be specially allocated items of Company income and gain (consisting of a pro rata portion of each item of
Company income, including gross income and gain for the Fiscal Year) in an amount and manner sufficient to eliminate, to the extent required by the Regulations, its Adjusted Capital Account Deficit. 

  
 19 

 (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be allocated
to the Members in accordance with their respective Interests. If the Sharyland Member determines in its good faith discretion that the Company’s Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor
requirements of the Regulations promulgated under Section 704(b) of the Code, the Sharyland Member is authorized, upon notice to the TDC Member, to revise the prescribed ratio for such Fiscal Year to the numerically closest ratio which would
satisfy such requirements. 
 (f) Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Fiscal Year shall be
specially allocated to the Member who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Regulations Sections 1.704-2(b)(4) and 1.704-2(i). 

(g) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to
Section 734(b) or 743(b) of the Code is required, pursuant to Regulations Section 1.704-l(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such Section of the Regulations. 
 (h) Curative Allocations. The allocations
set forth in this Section 4.6 (the “Regulatory Allocations”) are intended to comply with certain requirements of Treasury Regulations Sections 1.704-l(b) and 1.704-2. Notwithstanding any other provision of this
Section 4.1 (other than the Regulatory Allocations), the Sharyland Member is authorized to make offsetting special allocations of Company income, gain, loss or deduction in whatever manner it deems appropriate so that, after such
offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement and all Company
items were allocated pursuant to Section 4.1. 
 Section 4.7 Allocations for Tax Purposes. 

(a) Except as otherwise provided in this Section 4.7, for federal income tax purposes, each item of income, gain, loss and
deduction shall be allocated among the Members in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 4.1 and Section 4.6 hereof. 

  
 20 

 (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or
Adjusted Property, items of income, gain, loss, and deduction shall be allocated for federal income tax purposes among the Members as follows: 

(i) (A) In the case of a Contributed Property, such items attributable thereto shall be allocated among the Members consistent
with the principles of Section 704(c) of the Code to take into account the variation between the 704(c) Value of such property and its adjusted basis at the time of contribution (taking into account Section 4.7(c)); and (B) any
item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Members in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 4.1 and
Section 4.6 hereof. 
 (ii) In the case of an Adjusted Property, such items shall: 

(A) first, be allocated among the Members in a manner consistent with the principles of Section 704(c) of the Code to take
into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Section 3.4; 

(B) second, in the event such property was originally a Contributed Property, be allocated among the Members in a manner
consistent with Section 4.7(b)(i); and 
 (iii) any item of Residual Gain or Residual Loss attributable to an
Adjusted Property shall be allocated among the Members in the same manner its correlative item of “book” gain or loss is allocated pursuant to Section 4.1 and Section 4.6 hereof. 

(iv) all other items of income, gain, loss and deduction shall be allocated among the Members in the same manner as their
correlative item of “book” gain or loss is allocated pursuant to Section 4.1 and Section 4.6 hereof. 
 (c)
To the extent Regulations promulgated pursuant to Section 704(c) of the Code permit the Company to utilize alternative methods to eliminate the disparities between the Carrying Value of property and its adjusted basis, the Sharyland Member
shall, subject to the following, have the authority to elect the method to be used by the Company and such election shall be binding on all Members; provided that, to the extent that the Sharyland Member has agreed to use a particular method with
respect to a Contributed Property, the Sharyland Member shall be bound by such agreement pursuant to the terms thereof. 
 ARTICLE V.

 THE SHARYLAND MEMBER 

Section 5.1 Power and Authority of Sharyland Member. 

(a) (i) Except as provided in Section 5.2 and elsewhere in this Agreement and except as otherwise provided by applicable law, the
Sharyland Member shall have full and exclusive power and authority on behalf of the Company to manage, control, administer and operate the properties, business and affairs of the Company in accordance with this Agreement and to do or cause to be
done any and all acts deemed by the Sharyland Member to be necessary or appropriate thereto, and (except as aforesaid in this Section 5.1) the scope of such power and authority shall encompass all matters in any way connected with such
business or incident thereto, including property and asset management, compliance with governmental regulations 

  
 21 

 
and registration requirements and operational activities of the Company and the authority to bind the Company in making contracts and incurring obligations in the Company’s name in the
course of the Company’s business, including, without limitation, causing the Company to enter into, and be bound by the terms of, the Lease Agreements. Without limiting the generality of the foregoing, the Sharyland Member shall have the power
and authority to cause the Company to timely perform all of its obligations under all agreements binding upon the Company or its assets, including without limitation, all obligations under the Lease Agreements (including specifically the obligations
for Footprint Projects (x) required by Regulatory Authorities or (y) reasonably necessary to satisfy Sharyland Utilities’ or another lessee’s obligation as a regulated utility to serve its customers or to maintain the safety or
reliability of a System) and the loan agreements and related documents, including promissory notes and security documents, to which the Company is a party. Further, the Sharyland Member may in its reasonable discretion contract with third-party
service providers to perform any of the services it is obligated to provide to the Company under this Agreement. 
 (ii)
Notwithstanding the limitations in Section 5.2 or any other provision of this Agreement, the Sharyland Member shall have the power and authority on behalf of the Company, without the Approval of the TDC Member, to: 

(A) make any filing of changes in the Company’s or any of its subsidiaries’ rates or charges that are required to be
filed by Applicable Laws; and 
 (B) consistent with the Lease Agreements, (x) initiate regulatory proceedings with
Regulatory Authorities in accordance with Good Utility Practice, including rate proceedings, interim transmission cost of service filings and distribution cost recovery factor filings, (y) initiate, prosecute, defend and participate in any
administrative or judicial proceeding reasonably necessary or advisable to operate the System in an economical and efficient manner, provided that the Sharyland Member shall consult with the TDC Member prior to initiating any rate proceeding with
the PUCT to change the rates the Sharyland Member can lawfully charge, but, with or without the Approval of the TDC Member, the Sharyland Member shall be authorized to initiate any such rate proceeding. 

Furthermore, upon the TDC Member’s request, the Sharyland Member shall file a rate proceeding before the PUCT, and, in such circumstances,
the Company or the TDC Member shall be responsible for reimbursing the Sharyland Member for all costs associated with prosecution of such proceeding to the extent that such costs are not recoverable in the Sharyland Member’s PUCT-approved
rates. 
 (iii) The Sharyland Member may elect officers of the Company, who will have the powers and authority and will be
governed by the terms and provisions set forth below: 
 (A) Each officer of the Company shall be a natural person. An
officer need not be a resident of the State of Texas, a Member or an employee of the Company. 

  
 22 

 (B) The officers of the Company, if any, shall have such powers and authority,
subject to the direction and control of the Sharyland Member and shall perform such duties in connection with the management of the business and affairs of the Company as are provided in this Company Agreement, or as may be determined from time to
time by resolution of the Sharyland Member. In addition, except as otherwise expressly provided herein, each officer shall have such powers and authority as would be incident to his or her office if he or she served as a comparable officer of a
Texas corporation. 
 (C) The officers of the Company, if any, shall consist of a President, a Secretary and a Treasurer,
each of whom shall be elected by the Sharyland Member. In addition, the Sharyland Member shall have the authority to elect such other officers, including Vice Presidents and assistant officers, as it may from time to time determine. Any two or more
offices may be held by the same person. 
 (D) Any vacancy occurring in an office may be filled by the Sharyland Member. 

(E) Any officer of the Company may be removed by the Sharyland Member whenever in its judgment the best interests of the
Company will be served thereby, but such removal shall be without prejudice to the contract rights, if any, of the officer so removed. Election as an officer of the Company shall not of itself create any contract rights. 

(F) President. The President shall be the chief executive officer of the Company, and, under the direction and subject
to the control of the Sharyland Member, the President in general shall supervise and control all of the business and affairs of the Company and shall see that all orders and resolutions of the Sharyland Member are carried into effect. The President
may execute any deeds, mortgages, bonds, contracts or other instruments that the Sharyland Member has authorized to be executed and delivered, except in cases where the execution and delivery thereof shall be expressly and exclusively delegated to
another officer of the Company by the Sharyland Member or this Company Agreement, or where the execution and delivery thereof shall be required by law to be carried out by another person. In general, the President shall perform all duties incident
to the office of President and such other duties as may be prescribed from time to time by the Sharyland Member. 
 (G)
Vice Presidents. Each Vice President, if there be any, shall report to the President. Each Vice President may perform the usual and customary duties that pertain to such office (but not unusual or extraordinary duties or the duties conferred
by the Sharyland Member upon the President) and, under the direction and subject to the control of the Sharyland Member and the President, such other duties as may be assigned to him or her from time to time by the Sharyland Member or the President.
Any Vice President may be designated by the Sharyland Member as an Executive Vice President. 

  
 23 

 (H) Secretary. It shall be the duty of the Secretary to attend all
meetings of the Company and to record correctly the proceedings of such meetings and record all votes in a book suitable for such purposes. The Secretary shall give, or cause to be given, notice of all meetings of the Company. It shall also be the
duty of the Secretary to keep a register in which all transactions pertaining to the Membership Interests shall be correctly recorded. The Secretary shall also perform, under the direction and subject to the control of the Sharyland Member and the
President, such other duties as may be assigned to him or her from time to time. 
 (I) Treasurer. The Treasurer shall
have the care and custody of all the funds and securities of the Company that may come into his or her hands as Treasurer. The Treasurer may endorse checks, drafts and other instruments for the payment of money for deposit or collection when
necessary or proper and may deposit the same to the credit of the Company in such banks or depositories as the Sharyland Member may designate from time to time, and the Treasurer may endorse all commercial documents requiring endorsements for or on
behalf of the Company. The Treasurer may sign all receipts and vouchers for the payments made to the Company. The Treasurer shall render an account of his or her transactions to the Sharyland Member or the President as often as the Sharyland Member
or the President shall require from time to time. The Treasurer shall enter regularly in the books to be kept by him or her for that purpose, a full and adequate account of all monies received and paid by him or her on account of the Company. The
Treasurer shall also perform, under the direction and subject to the control of the Sharyland Member and the President, such other duties as may be assigned to him or her from time to time. 

(J) Delegation of Authority. In the case of any absence of any officer of the Company or for any other reason that the
Sharyland Member may deem sufficient, the Sharyland Member may delegate some or all of the powers or duties of such officer to any other officer for whatever period of time the Sharyland Member deems appropriate. 

(K) No Initial Officers. There shall be no officers until such time as the Sharyland Member elects such officers as
provided in this Section 5.1(a)(iii). 
 (b) The Sharyland Member shall, subject to the provisions of this Agreement and the
availability of cash funds of the Company, use reasonable efforts to implement the then applicable Approved Annual Business Plan, and, subject to the provisions of this Agreement, shall have all right, power and authority to do so. 

(c) In exercising its authority under this Section 5.1, the Sharyland Member shall have the power and authority to act alone, and
in the name and on behalf of the Company, including the power to execute for and on behalf of the Company any and all documents and instruments which may be necessary to carry on the business of the Company, in connection with the affairs of the
Company, except to the extent that (i) the prior Approval of the TDC Member 

  
 24 

 
is required pursuant to this Agreement, including but not limited to those described in Section 5.2 hereof, or (ii) any such action is otherwise prohibited, restricted or limited
under the provisions of this Agreement, in which case the Sharyland Member may exercise only such authority for which Approval has been given by the TDC Member or which is expressly permitted under this Agreement. Any third party conducting business
with the Company shall be entitled to rely on the authority of the Sharyland Member to conduct Company business solely by the execution of any documents or instruments by the Sharyland Member, and such third party shall not be required to determine
the authority of the Sharyland Member under this Agreement or to otherwise determine any fact or circumstance bearing upon the existence of the Sharyland Member’s authority to obligate or bind the Company or any fact relating to the Approved
Annual Business Plan. 
 (d) InfraREIT has elected or expects to elect to be treated as a REIT. In order to maintain its status as a REIT,
InfraREIT will be required to comply with numerous and complex rules and regulations set forth in the Code and the Regulations, many of which are applied on a quarterly and/or annual basis (the “REIT Requirements”), and the
management and operation of the Company by the Sharyland Member will have a material effect on the ability of InfraREIT to continue to maintain its status as a REIT. Accordingly, notwithstanding any other provision of this Agreement or any
non-mandatory provision of the Act, the Sharyland Member shall not permit the Company to take any action which (or omit to take any action, the omission of which) would result in (A) less than seventy-five percent (75%) of the assets of
the Company at the close of any calendar quarter qualifying as “real estate assets” under Section 856(c)(4)(A) of the Code, (B) more than twenty-five percent (25%) of the assets of the Company at the close of any calendar
quarter to consist of assets described in Section 856(c)(4)(B) of the Code, (C) any of the assets of the Company at the close of any calendar quarter to violate or exceed the limitations described in Section 856(c)(4)(B)(iii) of the
Code, (D) less than 75% of the gross income of the Company in any calendar year qualifying as income described in Section 856(c)(3) of the Code and less than 95% of gross income in any calendar year qualifying as income described in
Section 856(c)(2) of the Code, (E) any portion of the gross revenues or net income of the Company in any calendar year constituting income from a “prohibited transaction” as defined in Section 857(b)(6)(B)(iii) of the Code,
or (F) any material amount of the Company’s assets to be property described in Section 1221(a)(l) of the Code (other than “foreclosure property” as defined in Section 856(e) of the Code), (clauses (A), (B), (C), (D),
(E) and (F) are collectively referred to herein as the “REIT Restriction Covenants”). 
 The foregoing provisions
are intended to ensure that the assets, income and operations of the Company are such that they will satisfy the various provisions of the Code that restrict the assets, income and operations of REITs and thereby ensure that the REIT status of
InfraREIT will not be jeopardized by its direct or indirect ownership of an interest in the Company. In the event that any additional restrictions on the assets, income or operations of REITs are imposed by any new provisions of the Code or
Regulations, any amendments to the Code or Regulations or by any judicial precedent or any notice, ruling or release of the U.S. Treasury Department or the IRS, then upon written advice of InfraREIT’s counsel, the Sharyland Member shall agree
to amend the provisions of this Section 5.1(d) as required to ensure that the assets, income or operations of the Company will not jeopardize the REIT status of InfraREIT. Notwithstanding any other provision of this Agreement to the
contrary, any expenses related to any amendment made pursuant to this Section 5.1(d) or to maintain compliance by the Company with the REIT Requirements or the REIT Restriction Covenants or to continue InfraREIT’s maintenance of its
REIT status shall be borne solely by InfraREIT. 

  
 25 

 Section 5.2 Restrictions on Sharyland Member. 

(a) Notwithstanding anything in this Agreement to the contrary, including without limitation Section 5.1, except to the extent
required by Applicable Laws, the Sharyland Member shall have no authority to do or permit any of the following acts on behalf of the Company or any of its subsidiary entities without the Approval of the TDC Member (it being recognized that the
Approval for any particular act may be contemplated by an Approved Annual Business Plan):

contravention of this Agreement or which would make it impossible or unreasonably burdensome to carry on the business of the Company; 

(ii) confess a judgment against the Company in any material amount; 

(iii) borrow any money from the Company; 

(iv) do any other act which the Act specifically requires to be Approved by the Members;

(vi) Any sale, exchange or other Transfer of any assets of the Company or any of its subsidiaries;

its subsidiaries to third parties (including, without limitation, their employees and consultants pursuant to equity awards under any equity incentive program), including any material modification thereof, except as provided in
Section 3.2(d); 
 (ix) Any open market purchases of publicly traded securities;

Practice, or (iii) necessary in an Emergency if, under the circumstances, in the good faith estimation of the Sharyland Member, there is insufficient time to allow the Sharyland Member to obtain the Approval of the TDC Member to such action and

Utility Practices. The Sharyland Member shall notify the TDC Member of each such action or as soon as reasonably practicable thereafter.

Cause Event or, if such For Cause Event is not reasonably capable of being cured or corrected within such thirty (30) day period, the Sharyland Member has not commenced to cure or correct such For Cause Event during such thirty (30) day

 THE MEMBERS 

Section 6.1 Rights of the Members. In addition to the other rights specifically set forth herein, each Member shall have the right
to: (a) have the books and records of the Company and each subsidiary entity (including without limitation those required in the Act) kept at the principal United States office of the Company and at all reasonable times to inspect and copy any
of them, (b) have on demand true and full information of all things affecting the Company and any subsidiary Entity and a formal account of the affairs of the Company and any subsidiary Entity, (c) have winding up of the Company by decree
of court as provided for in the Act, (d) exercise all rights of a member under the Act (except to the extent otherwise specifically provided for herein) and (e) take, consent to, waive and/or approve all actions and requirements, vote and
make all elections permitted or required under or pursuant to this Agreement. 

  
 29 

 Section 6.2 Liability for the Company’s Obligations. Except as otherwise
required by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Members shall not be obligated personally for
any such debt, obligation or liability solely by reason of being a Member of the Company. Each Member shall be obligated to make payment of its contributions of capital as and when due hereunder and other payments as provided in this Agreement. 

Section 6.3 Use of Affiliates. Any right, power, circumstance or situation wherein a Member may take or require certain actions
may be undertaken through an Affiliate of such Member. 
 ARTICLE VII. 

INDEMNIFICATION 

Section 7.1 Liability of the Covered Persons. Notwithstanding anything to the contrary set forth in this Agreement, no Covered
Person shall be liable for monetary damages to the Company, or any other Member for losses sustained, liabilities incurred or benefits not derived as a result of errors in judgment or mistakes of fact or law or of any act or omission unless such
Covered Person acted in bad faith and the act or omission was material to the matter giving rise to the loss, liability or benefit not derived. 

Section 7.2 Indemnification. 

(a) The Company shall indemnify each Covered Person to the fullest extent provided by the Act from and against any and all losses, claims,
damages, liabilities, joint or several, expenses (including, without limitation, attorneys’ fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from or in connection with any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative, incurred by such Covered Person and relating to the Company or a Member or the operation of, or the ownership of property by, the Company or such Member as set forth in
this Agreement in which any such Covered Person may be involved, or is threatened to be involved, as a party or otherwise, unless it is established by a final determination of a court of competent jurisdiction that: (i) the act or omission of
such Covered Person was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty, (ii) such Covered Person actually received an improper personal benefit in
money, property or services or (iii) in the case of any criminal proceeding, such Covered Person had reasonable cause to believe that the act or omission was unlawful. Without limitation, the foregoing indemnity shall extend to any liability of
any Covered Person, pursuant to a loan guarantee, contractual obligation for any indebtedness or other obligation or otherwise, for any indebtedness of the Company (including, without limitation, any indebtedness which the Company has assumed or
taken subject to), and the Sharyland Member is hereby authorized and empowered, on behalf of the Company, to enter into one or more indemnity agreements consistent with the provisions of this Section 7.2 in favor of any Covered Person
having or potentially having liability for any such indebtedness. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Covered Person did not meet the requisite standard of conduct set forth in
this Section 7.2.(a). The termination of any 

  
 30 

 
proceeding by conviction or upon a plea of nolo contendere or its equivalent, or an entry of an order of probation prior to judgment, creates a rebuttable presumption that the Covered Person
acted in a manner contrary to that specified in this Section 7.2 with respect to the subject matter of such proceeding. Any indemnification pursuant to this Section 7.2 shall be made only out of the assets of the Company, and
any insurance proceeds from the liability policy covering a Member and any Covered Person, and neither the Sharyland Member nor any TDC Member shall have any obligation to contribute to the capital of the Company or otherwise provide funds to enable
the Company to fund its obligations under this Section 7.2. 
 (b) Reasonable expenses paid or expected to be incurred by a
Covered Person shall be paid or reimbursed by the Company in advance of the final disposition of any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative made or threatened against a Covered Person
upon receipt by the Company of (i) a written affirmation by the Covered Person of the Covered Person’s good faith belief that the standard of conduct necessary for indemnification by the Company as authorized in this
Section 7.2 has been met and (ii) a written undertaking by or on behalf of the Covered Person to repay the amount if it shall ultimately be determined that the standard of conduct has not been met. 

(c) The indemnification provided by this Section 7.2 shall be in addition to any other rights to which a Covered Person or any
other Person may be entitled under any agreement, pursuant to any vote of the Members, as a matter of law or otherwise, and shall continue as to a Covered Person who has ceased to serve in such capacity unless otherwise provided in a written
agreement pursuant to which such Covered Person is indemnified. 
 (d) The Company may purchase and maintain insurance on behalf of the
Covered Persons and such other Persons as the Sharyland Member shall determine against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Company’s activities, regardless of whether
the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement. 
 (e) In no event
may a Covered Person subject any of the Members to personal liability by reason of the indemnification provisions set forth in this Agreement. 

(f) A Covered Person shall not be denied indemnification in whole or in part under this Section 7.2 because the Covered Person had
an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

(g) The provisions of this Section 7.2 are for the benefit of the Covered Persons, their employees, officers, directors, trustees,
partners, members, heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 7.2, or any provision hereof, shall
be prospective only and shall not in any way affect the limitation on the Company’s liability to any Covered Person under this Section 7.2 as in effect immediately prior to such amendment, modification or repeal with respect to
claims arising from or related to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 

  
 31 

 (h) If and to the extent any payments to a Member pursuant to this Section 7.2
constitute gross income to such Member (as opposed to the repayment of advances made on behalf of the Company), such amounts shall constitute guaranteed payments within the meaning of Section 707(c) of the Code, shall be treated
consistently therewith by the Company and all Members, and shall not be treated as distributions for purposes of computing the Members’ Capital Accounts. 

ARTICLE VIII. 
 COMPANY
OPERATIONS 
 Section 8.1 Annual Business Plan; Capital Expenditures Budget. 

(a) No later than November 15th of each Fiscal Year, the Sharyland Member shall prepare and submit to the TDC Member for its Approval a
proposed Annual Business Plan for the next Fiscal Year (each, an “Annual Business Plan”). The parties agree that any annual business plan of InfraREIT that includes forecasted expenditures for the Company may be deemed an Annual
Business Plan hereunder. The Annual Business Plan shall, as a separate line item, specify (without limitation) (i) each category of the operating expenses of the Company and any of its subsidiaries, and (ii) the Capital Expenditure Budget.
Except as otherwise contemplated by Section 5.2(a)(xi), Section 8.1(b) or Section 8.1(c), no increases from any category of operating expenses or capital expenditure item in an Approved Annual Business Plan shall
be made (and no expenditures shall be made for any such increased amounts therein) without the prior Approval of the TDC Member. With respect to the portion of the Annual Business Plan that is comprised of the Capital Expenditure Budget, the
Sharyland Member has provided to the TDC Member the approximate amounts of capital expenditures that the Sharyland Member expects will be needed for purposes of funding Footprint Projects in each Fiscal Year through 2016. No later than
October 15th of each calendar year, the Sharyland Member shall review and revise the Capital Expenditure Budget on a rolling three-year basis, 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 Capital Expenditure 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 “Capital Expenditure Budget”) and shall submit the Capital Expenditure Budget to the TDC Member for its Approval. The parties envision that the Capital
Expenditure Budgets will be the aggregate of all capital expenditures included in CapEx Budgets (as such term is defined in the Lease Agreements) delivered pursuant to the Lease Agreements. 

(b) As soon as practicable after any proposed Annual Business Plan is submitted to the TDC Member but no later than forty-five (45) days
after receipt by the TDC Member, the TDC Member shall Approve or disapprove such proposed Annual Business Plan. If the proposed Annual Business Plan is Approved by the TDC Member, then such proposed Annual Business Plan shall be deemed thereafter to
constitute the Approved Annual Business Plan for the Fiscal Year in question for all purposes hereof, subject to amendment from time to time. If the TDC Member does not Approve the proposed Annual Business Plan, it shall notify the Sharyland Member
of its reason(s) for not granting such Approval. The Members shall use their best efforts to resolve any questions with respect to revisions to the proposed Annual Business Plan and to agree upon an Annual Business Plan for the Fiscal Year in
question prior to 

  
 32 

 
the beginning of the Fiscal Year to which such Annual Business Plan relates. In the event an Annual Business Plan for any Fiscal Year is not Approved by the TDC Member prior to the commencement
thereof, the Sharyland Member shall continue to manage, maintain, supervise and direct the Company in accordance with the applicable Approved Annual Business Plan for the previous Fiscal Year dealing solely with maintaining and preserving the assets
of the Company in accordance with reasonable, prudent and consistent Good Utility Practices, such as the payment of taxes, insurance, debt service and other expenses necessary to maintain the essential day-to-day operations of the assets of the
Company until a new Annual Business Plan is Approved by the TDC Member; provided, however, the Sharyland Member shall be authorized during any interim period to reasonably exceed the budgeted amounts for taxes, insurance, debt service and other
costs if the cost of such items has increased above the amounts budgeted therefor for the prior Fiscal Year and such payments are required to preserve the value of the assets. 

(c) The Sharyland Member shall have the right from time to time during each Fiscal Year to prepare and submit to the TDC Member for its
Approval proposed amendments to the Approved Annual Business Plan for such Fiscal Year. The TDC Member shall, within ten (10) days, Approve, disapprove or make such revision thereto as the TDC Member may deem necessary and proper, which
Approval may be withheld by the TDC Member in its sole discretion. The TDC Member shall use its reasonable best efforts to provide some form of response within such ten (10) day period, but a failure of the TDC Member to respond within such ten
(10) day period shall constitute disapproval of such amendment. Once Approved by the TDC Member, or so revised by the TDC Member and Approved by the Sharyland Member, such amendments shall be incorporated into and become part of the Approved
Annual Business Plan for the Fiscal Year in question. Notwithstanding anything to the contrary contained in this Agreement, amendments or modifications of the Approved Annual Business Plan which reflect changes as a result of an increase in Working
Capital Reserve for Required Footprint Projects shall be submitted to the TDC Member but shall not require the Approval of the TDC Member. 

(d) Any modifications made to an Annual Business Plan at the request of the TDC Member after submission by the Sharyland Member must also be
Approved by the Sharyland Member before the Annual Business Plan is Approved by the Members. It is possible that an Annual Business Plan, or an amendment thereto, may be partially Approved and partially disapproved, in which event, the Sharyland
Member shall proceed to conduct business on the basis of the Annual Business Plan to the extent that it is so Approved. 
 (e) The TDC Member
agrees that a Capital Expenditure Budget may contain Footprint Project(s) that require multi-year commitments of funds, capital or credit enhancement. If the TDC Member Approves a multi-year commitment of funds, capital or credit enhancement for
such Footprint Projects, the Sharyland Member shall not be required to obtain the re-Approval of the TDC Member for such expenditures or commitments in subsequent years, and such commitments and expenditures shall remain Approved by the TDC Member
for purposes of this Agreement whether or not the TDC Member Approves subsequent Annual Business Plans and/or Capital Expenditure Budgets proposed by the Sharyland Member provided that, other than as contemplated by Section 5.2(a)(xi),
Section 8.1(b) or Section 8.1(c), any increase in expenditures or commitments for such Footprint Projects does not exceed 105% of the amounts set forth in the then current Approved Annual Business Plan for the year in
question and there 

  
 33 

 
has been no material increase in time for completion of such Footprint Projects in the current schedule compared to the schedule previously Approved by the TDC Member. Any Footprint Projects with
a multi-year commitment must be so designated in the applicable Capital Expenditure Budget and must be the type of Footprint Projects that in the ordinary course of business would be conducted on an extended or multi-year basis as opposed to an
annual basis to qualify for the special continuation of funding or commitment without re-Approval provisions of this Section 8.1(e). Continuing Approval of multi-year projects is conditioned upon the cost of the applicable Footprint
Project being within 105% of the amounts set forth in the then current Approved Annual Business Plan with no material increase in time for completion in the current schedule compared to the schedule presented when the Footprint Project was
previously Approved by the TDC Member. If the Footprint Project budget is in excess of 105% of the amounts set forth in the then current Approved Annual Business Plan or there has been a material increase in the time for completion compared to the
schedule previously Approved by the TDC Member, then the increase in the cost of the Footprint Project must be again presented to the TDC Member for Approval with such revised budgets and project schedules as the Sharyland Member shall reasonably
determine. 
 Section 8.2 Insurance. Insurance with respect to the affairs, activities, operations, business, Footprint Projects
and other assets of the Company shall be maintained as reasonably required for ownership and prudent operation of electric transmission and distribution facilities as determined by the Sharyland Member from time to time, or any specific provision of
an Approved Annual Business Plan. 
 ARTICLE IX. 

ACCOUNTING AND RECORDS 

Section 9.1 Books and Records. 

(a) The Sharyland Member, at the Company’s expense, shall keep at the Company’s principal office separate books of account for the
Company which shall show a true and accurate record of all costs and expenses incurred, all charges made, all credits made and received and all income derived in connection with the operation of the Company’s business in accordance with GAAP as
to the Company’s financial position and results of operations. The Sharyland Member 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 Company’s assets by Applicable Laws or by reasonable and prudent Good Utility Practices.

 (ii) Quarterly: portfolio reporting forms in such form and containing
such information regarding the performance of the Company and its subsidiaries, as the TDC Member may request from time to time within forty-five (45) days following the last day of each calendar quarter. 

(iii) Periodically: at least ten (10) days prior to each estimated tax payment date of the TDC Member, an estimate of the
taxable income of the Company allocable to the TDC Member for the period for which such estimated tax payment relates, provided that the TDC Member shall furnish the Sharyland Member with notice as to each such estimated tax payment date and
applicable period. 
 (iv) Quarterly: (x) financial statements and other information required under Applicable Laws and
by Good Utility Practices, and (y) such additional information, as may be necessary or desirable for an entity subject to the reporting requirements of the Exchange Act, including the Sarbanes-Oxley Act of 2002. 

(v) Other: such other financial statements, budgets, plans and schedules as are from time to time reasonably requested by the
TDC Member. 
 (b) The foregoing, to the extent applicable, shall be prepared using GAAP and shall cover the immediately preceding month or
quarter, as the case may be, plus the current Fiscal Year through the end of such preceding month or quarter, as the case may be, on both an actual and year-to-date budgeted basis. 

Section 9.3 Annual Audit. Within ninety (90) days after the end of each Fiscal Year, a general accounting and audit of the
Company in accordance with GAAP shall be completed by the Accountants at the expense of the Company and delivered to the TDC Member by the Sharyland Member. The audit shall be conducted in accordance with the auditing standards of the Public Company
Accounting Oversight Board and shall include a balance sheet, statement of operations, statement of members’ capital and statement of cash flows as of and for the Fiscal Year ended as well as appropriate disclosures as required by GAAP and the
auditing standards of the Public Company Accounting Oversight Board. The Company shall prepare or cause the Accountants to prepare, such additional information as may be necessary or desirable for an entity subject to the reporting requirements of
the Exchange Act, including the Sarbanes-Oxley Act of 2002. In addition, the Sharyland Member, at the expense of the Company, will cause supplemental schedules to the audit report to be included for items or information, such as an audit of
Available Cash, as the TDC Member may request. If the additional information requested by the TDC Member cannot be adequately presented as part of the audit report, the Sharyland Member, at the expense of the Company, will engage the Accountants to
perform additional attestation services sufficient to comply with the TDC Member’s request. 

  
 35 

 Section 9.4 Exchange Act Reporting. Notwithstanding anything to the contrary in
Section 9.2 or Section 9.3, the Company shall prepare or cause the Accountants to prepare, such additional information relating to the Company, its assets and operations as may be necessary or desirable in order to allow
InfraREIT to comply with the reporting requirements of the Exchange Act and any other applicable laws or exchange listing requirements. 

Section 9.5 Fiscal Year. The “Fiscal Year” (herein so called) of the Company shall be the calendar year, unless
otherwise Approved by the Members. As used in this Agreement, a Fiscal Year shall include any partial calendar year at the beginning and end of the Company term. 

Section 9.6 Bank Accounts. 

(a) The Sharyland Member shall exercise its commercially reasonable best efforts for the safekeeping and use of all funds and assets of the
Company, whether or not in its immediate possession or control. The funds of the Company shall not be commingled with the funds of any other Person and the Sharyland Member shall not employ, or permit any other Person to employ, such funds in any
manner except for the benefit of the Company. At the Company’s expense, all signatories on Company bank accounts shall be bonded in an amount and by a fidelity insurance carrier Approved by the TDC Member in the exercise of its reasonable
discretion. 
 (b) The bank accounts of the Company shall be maintained in the Bank and withdrawals shall be made only in the regular course
of Company business and as otherwise authorized in this Agreement on such signature or signatures as the Sharyland Member may determine. 

Section 9.7 Quarterly Meetings. At least once during each calendar quarter, the Members shall meet in Dallas, Texas or at such
other place as may be mutually agreed upon by the Members, at which time the Sharyland Member shall report on the affairs of the Company and the progress being made under the then applicable Approved Annual Business Plan. The meeting of the Members
during the last calendar quarter of each Fiscal Year shall be for the purpose of reviewing and approving the Annual Business Plan for the next succeeding year. The Sharyland Member shall be responsible for scheduling the quarterly meetings and shall
give at least ten (10) days prior written notice to the other Member of the time and place of the meeting. The costs and expenses of each quarterly meeting shall be borne by the Company.

 ARTICLE X. 

TAX MATTERS 

Section 10.1 Preparation of Tax Returns. The Sharyland Member shall arrange for the preparation and timely filing of all returns
of Company income, gains, deductions, losses and other items required of the Company for federal and state income tax purposes and shall use all reasonable efforts to furnish, within one hundred and fifty (150) days of the close of each Taxable
Year, the tax information reasonably required by the TDC Member for federal and state income tax reporting purposes. 
 Section 10.2
Tax Elections. Except as otherwise provided herein, the Sharyland Member shall, in its sole and absolute discretion, determine whether to make any available election pursuant to the Code; provided, however, that the Sharyland Member shall
make the election under Section 754 of the Code in accordance with applicable regulations thereunder. The Sharyland Member shall have the right to seek to revoke any such election (including, without limitation, the election under
Section 754 of the Code) upon the Sharyland Member’s determination in its sole and absolute discretion that such revocation is in the best interests of the Members. 

Section 10.3 Tax Matters Member. 

(a) General. The Sharyland Member shall be the “tax matters partner” of the Company for federal income tax purposes as defined
in Section 6231 of the Code (the “Tax Matters Member”). Pursuant to Section 6223(c)(3) of the Code, upon receipt of notice from the IRS of the beginning of an administrative proceeding with respect to the Company, the Tax
Matters Member shall furnish the IRS with the name, address, taxpayer identification number and profit interest of each Member and any of its assignees; provided, however, that such information is provided to the Company by such Member. 

(b) Powers. The Tax Matters Member is authorized, but not required: 

(i) to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of
Company items required to be taken into account by a Member for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in
the settlement agreement the Tax Matters Member may expressly state that such agreement shall bind all Members, except that such settlement agreement shall not bind any Member (A) who (within the time prescribed pursuant to the Code and
Regulations) files a statement with the IRS providing that the Tax Matters Member shall not have the authority to enter into a settlement agreement on behalf of such Member or (B) who is a “notice partner” (as defined in
Section 6231(a)(8) of the Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code); 

  
 37 

 (ii) if a notice of a final administrative adjustment at the Company level of any
item required to be taken into account by a Member for tax purposes (a “Final Adjustment”) is mailed to the Tax Matters Member, to seek judicial review of such final adjustment, including the filing of a petition for readjustment
with the Tax Court or the filing of a complaint for refund with the United States Claims Court or the District Court of the United States for the district in which the Company’s principal place of business is located; 

(iii) to intervene in any action brought by any other Member for judicial review of a Final Adjustment;

(v) to enter into an agreement with the IRS to extend the period for assessing any tax which is attributable to any item
required to be taken into account by a Member for tax purposes, or an item affected by such item; and 
 (vi) to take any
other action on behalf of the Members of the Company in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations. 

The taking of any action and the incurring of any expense by the Tax Matters Member in connection with any such proceeding, except to the
extent required by law, is a matter in the sole and absolute discretion of the Tax Matters Member and the provisions relating to indemnification of the Sharyland Member set forth in Article VII shall be fully applicable to the Tax Matters
Member in its capacity as such. 
 (c) Reimbursement. The Tax Matters Member shall receive no compensation for its services. All third
party costs and expenses incurred by the Tax Matters Member in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Company. Nothing herein shall be construed to restrict the Company from engaging an
accounting firm and/or law firm to assist the Tax Matters Member in discharging its duties hereunder, so long as the compensation paid by the Company for such services is reasonable. 

Section 10.4 Organizational Expenses. The Company shall elect to deduct expenses, if any, incurred by it in organizing the Company
ratably over a one hundred eighty (180) month period as provided in Section 709 of the Code. 
 Section 10.5
Withholding. Each Member hereby authorizes the Company to withhold from or pay on behalf of or with respect to such Member any amount of federal, state, local, or foreign taxes that the Sharyland Member determines the Company is required to
withhold or pay with respect to any amount distributable or allocable to such Member pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Company pursuant to Section 1441, 1442, 1445, or
1446 of the Code. Any amount paid on behalf of or with respect to a Member shall constitute a loan by the Company to such Member, which loan shall be repaid by such Member within fifteen (15) days after notice from the Sharyland Member that
such payment must be made unless (i) the Company withholds such payment from a distribution which would otherwise be made to the Member or (ii) the Sharyland Member determines, in its sole and absolute discretion, that such payment may be
satisfied out of 

  
 38 

 
the available funds of the Company which would, but for such payment, be distributed to the Member. Any amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be treated
as having been distributed to such Member. Each Member hereby unconditionally and irrevocably grants to the Company a security interest in its Interest to secure such Member’s obligation to pay to the Company any amounts required to be paid
pursuant to this Section 10.5. If a Member fails to pay any amounts owed to the Company pursuant to this Section 10.5 when due, the Sharyland Member may, in its’ sole and absolute discretion, elect to make the payment to
the Company on behalf of such defaulting Member, and in such event shall be deemed to have loaned such amount to such defaulting Member and shall succeed to all rights and remedies of the Company as against such defaulting Member (including, without
limitation, the right to receive distributions). Any amounts payable by a Member hereunder shall bear interest at the base rate on corporate loans at large United States money center commercial banks, as published from time to time in the Wall
Street Journal, plus four (4) percentage points per annum (but not higher than the maximum lawful rate under the laws of the State of Texas) from the date such amount is due (i.e., fifteen (15) days after demand) until such amount is paid
in full. Each Member shall take such actions as the Company or the Sharyland Member shall request to perfect or enforce the security interest created hereunder. 

Section 10.6 Code Section 83 Safe Harbor Election. By executing this Agreement, each Member authorizes and directs the
Company to elect to have the “Safe Harbor” described in the proposed Revenue Procedure set forth in Internal Revenue Service Notice 2005-43 (the “Notice”) apply to any interest in the Company transferred to a service
provider by the Company on or after the effective date of such Revenue Procedure in connection with services provided to the Company. For purposes of making such Safe Harbor election, the Tax Matters Member is hereby designated as the “partner
who has responsibility for federal income tax reporting” by the Company and, accordingly, execution of such Safe Harbor election by the Tax Matters Member constitutes execution of a “Safe Harbor Election” in accordance with
Section 3.03(1) of the Notice. The Company and each Member hereby agree to comply with all requirements of the Safe Harbor described in the Notice, including, without limitation, the requirement that each Member shall prepare and file all
federal income tax returns reporting the income tax effects of each “Safe Harbor Partnership Interest”) (as described in Section 3.02 of the Notice) issued by the Company in a manner consistent with the requirements of the Notice.
Each Member authorizes the Tax Matters Member to amend this Section 10.6 to the extent necessary to achieve substantially the same tax treatment with respect to any interest in the Company transferred to a service provider by the Company
in connection with services provided to the Company as set forth in Section 4 of the Notice (e.g., to reflect changes from the rules set forth in the Notice in subsequent Internal Revenue Service guidance), provided that such amendment
is not materially adverse to any Member (as compared with the after-tax consequences that would result if the provisions of the Notice applied to all interests in the Company transferred to a service provider by the Company in connection with
services provided to the Company).

TRANSFER OF INTERESTS 

Section 12.1 Restrictions on Transfer. Except as expressly provided for in this Agreement, no Member may, without the Approval of
the other Member, sell, convey, transfer, assign, mortgage, pledge, hypothecate or otherwise encumber in any way (“Transfer”) all or any portion of or interest in its Interest or any interest it may have in any property of the
Company, or withdraw or retire from the Company. Any such attempted Transfer, withdrawal or retirement not permitted hereunder shall be null and void. Notwithstanding anything herein to the contrary, no Transfer of an Interest shall be valid unless
and until all necessary Regulatory Approvals applicable to such Transfer have been obtained. 
 Section 12.2 General Transfer
Provisions. 
 (a) All Transfers shall be by instrument in form and substance satisfactory to counsel for the Company and shall contain
an agreement by the assignee to accept the assignment and to accept and agree to all of the terms and provisions of this Agreement, as the same may have been amended, and shall provide for the payment by the assignor of all reasonable expenses
incurred by the Company in connection with such assignment, including, without limitation, the necessary amendments to this Agreement to reflect such Transfer (including, without limitation, reasonable attorneys’ fees). The transferor shall
execute and acknowledge all such instruments, in form and substance reasonably satisfactory to the Company’s counsel, as may be necessary or desirable to effectuate such Transfer. 

(b) In no event shall the Company terminate (other than for tax purposes) upon the admission of any Member to the Company or upon any permitted
assignment of an Interest by any Member. Each Member hereby waives its right to liquidate or terminate the Company in such event. 
 (c) Upon
completion of a Transfer in compliance with this Agreement, the transferor shall be released from all future obligations occurring under this Agreement, after the date of such Transfer, provided the assignee of such transferor assumes, by written
instrument reasonably acceptable to the Company, all such obligations of the transferor. Notwithstanding the immediately preceding sentence, the transferor shall remain liable for its obligations under this Agreement accruing or occurring on or
prior to the date of such Transfer. 
 (d) Notwithstanding anything to the contrary in this Section 12.2, the TDC Member may
mortgage, pledge or otherwise Transfer its Interest to a third party as collateral in connection with a bona fide financing transaction. 

Section 12.3 Compliance. Notwithstanding anything to the contrary in this Agreement, at law or in equity, no Partner shall
Transfer or otherwise deal with any Interest in a way that would cause a default under any agreement to which the Company is a party or by which it is bound. 

ARTICLE XIII. 

TERMINATION OF THE COMPANY 

Section 13.1 Events of Winding Up. The Company shall commence to wind up upon the first to occur of the following events: 

  
 41 

 (a) the sale or other disposition (including, without limitation, taking by eminent domain) of
all or substantially all of the assets of the Company (subject to any required Regulatory Approvals) unless such sale or other disposition involves any deferred payment of the consideration for such sale or disposition, in which case the Company
shall not commence to wind up until the last day of the calendar year during which the Company shall receive the balance of such deferred payment; 

(b) the agreement of the Members in writing to wind up the Company; 

(c) the occurrence of an Event of Bankruptcy with respect to the Sharyland Member, unless within ninety (90) days after such Event of
Bankruptcy the TDC Member consents in writing to continue the business of the Company and to the appointment effective as of the date of such Event of Bankruptcy, of a substitute Sharyland Member; 

(d) the issuance of a decree of winding up by a court of competent jurisdiction; or 

(e) the occurrence of any other event or action which requires winding up of the Company under Applicable Laws. 

Section 13.2 Effect of Winding Up. Upon an event requiring winding up of the Company pursuant to Section 13.1, the
Company shall not terminate but shall continue for the purposes (i) of obtaining any necessary Regulatory Approvals required as result of the occurrence of any of the events described in Section 13.1; (ii) as may be required by
any Regulatory Agency; and (iii) of distributing or liquidating all of the assets owned by the Company and, if liquidating, collecting the proceeds from such sales and all receivables of the Company until the same has been written off as
uncollectible. Upon an event requiring winding up of the Company, the Company shall continue to operate its business in the ordinary course consistent with reasonable and prudent Good Utility Practices, until such time as all necessary Regulatory
Approvals relating to the liquidation of the Company have been obtained, but otherwise engage in no further business thereafter other than as necessary for the Company to collect its receivables, liquidate and/or distribute its assets and pay or
discharge its liabilities. The liquidating distribution of assets, whether in cash or in kind as hereinafter provided, shall occur in accordance with Section 4.3 hereof. It is intended that the foregoing distributions to each Member will
be equal to each Member’s respective positive Capital Account balance as determined after giving effect to all adjustments attributable to allocations of items of income, gain, loss and deduction realized by the Company during the Fiscal Year
in question (including items of gain and loss realized on the sale of all properties and assets of the Company pursuant to this Section 13.2 and all adjustments attributable to contributions and distributions of money and property
effected prior to such distribution) as described in Section 4.1. To the extent that any such Member’s positive Capital Account balance does not correspond to such distribution, the allocations provided for in Section 4.1
shall be adjusted, to the least extent necessary, to produce a Capital Account balance for the Member which corresponds to the amount of such distribution. 

  
 42 

 Section 13.3 Sale or Distribution of Assets Resulting from Liquidation. 

(a) Unless the Company is continued pursuant to Section 13.1(c), upon an event requiring winding up of the Company, the Sharyland
Member or, if the winding up is caused by an Event of Bankruptcy of the Sharyland Member, a third party appointed by the TDC Member, shall act as liquidator trustee (the “Liquidating Trustee”) of the Company and shall diligently
proceed to wind up the affairs of the Company in accordance with a plan of liquidation approved by the Members, or, in the case of winding up of the Company caused by an Event of Bankruptcy, by the TDC Member. Such plan of liquidation shall provide
that the Company shall continue to operate its business in the ordinary course consistent with reasonable and prudent Good Utility Practices, until such time as all necessary Regulatory Approvals relating to the liquidation of the Company have been
obtained. Another Person may be selected by a majority vote of the Interests to succeed the original Liquidating Trustee, or to succeed any subsequently selected successor, whenever the Person originally selected or any such subsequently selected
successor, as the case may be, fails for any reason to carry out such purpose. The Liquidating Trustee may be an individual, corporation or general or limited partnership or other Entity. 

(b) The Liquidating Trustee shall promptly after an event requiring winding up obtain an appraisal of the assets of the Company by an appraiser
with appropriate experience in valuing the types of assets and properties then owned by the Company as selected by the Liquidating Trustee. All of the assets of the Company remaining after any required distributions of such assets in kind as
Approved by Members under the terms of this Agreement, other than cash, shall be offered (either as an entirety or on an asset-by-asset basis) promptly for sale, upon such terms as the Liquidating Trustee shall determine using the foregoing
appraisal as a guide. 
 (c) The Members and their Affiliates shall have the right to negotiate or bid for any or all of the remaining assets
being offered for sale from and after the date of an event requiring winding up of the Company, but not before such date. 
 (d) The decision
to accept or reject an offer to purchase any remaining assets of the Company (a “Purchase Offer”) shall be made solely by the Liquidating Trustee; provided that, if the Sharyland Member is the Liquidating Trustee and proposes to
sell such remaining assets to itself or an Affiliate, the terms of such sale must be Approved by the TDC Member. 
 (e) In winding up the
affairs of the Company, the Liquidating Trustee shall pay the liabilities of the Company in such order of priority as provided by law. 

ARTICLE XIV.
