Facility Plan is approved by Unanimous Consent as provided in Section 2.9(b)(iii), then the Board shall instruct the relevant Operator to proceed in accordance with the applicable Facility Plan with the development of such Facility
Opportunity, the Facility Plan shall be deemed approved for all purposes and the Facility Budget shall be incorporated into the Budget accordingly. 
 (v) If the Board does not approve the Facility Opportunity pursuant to Section 2.9(b)(iii) by Unanimous Consent, then (A) if a Member, through its representation on the Board, shall have
voted to approve such Facility Opportunity (the “Consent Member”), the provisions of Section 2.9(c) shall apply, or (B) if no Member, through its representation on the Board, shall have voted to approve such
Facility Opportunity, such Facility Opportunity shall be deemed rejected by the Board, and no Member, or its Affiliates, may pursue it. 
 (vi) Except in connection with costs associated with the feasibility study described under Section 2.9(b)(i) or actions otherwise taken with the approval of the Board, the Company shall not
incur any material costs or obligations with respect to a Facility Opportunity until (A) the necessary Permits for the Facility Opportunity have been obtained and all other applicable legal requirements have been satisfied, including (if
applicable) the expiration of all applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1996, as amended, (B) the estimated cost of the Facility Opportunity has been determined by the Board and (C) Unanimous
Consent of such Facility Opportunity has been obtained as provided in Section 2.9(b)(iii).

Section 3.9. 
 Section 3.5 Restrictions on the Transfer of a Membership Interest. Any Transfer

 (d) The Company may, in its reasonable discretion, charge the
Transferring Member a reasonable fee to cover administrative expenses necessary to effect a Transfer with respect to any or all of such Member’s Membership Interest. 
 (e) In the absence of the substitution (as provided herein) of a Transferee for a Transferring Member, any payment by the
Company to the Transferring Member shall acquit the Company and the Members of all liability to any other Persons who may be interested in such payment by reason of a Transfer by such Member. 
 (f) Neither the Company nor any Member shall be bound or otherwise affected by any Transfer of any Membership Interest with
respect to which such Person has not received notice pursuant to Section 3.7. 
 (g) Except as
specifically provided under Section 3.6(c) or 3.6(d), a Member in Default shall not Transfer, and shall not permit a Transfer of, its Membership Interest. 
 Section 3.6 Permitted Transfers. 
 (a) Transfers to Affiliates. Any Member may Transfer all, and not less than all, of its Membership Interest to a
Wholly-Owned Affiliate of its Parent without being subject to the requirements of Section 3.6(b); provided that (i) such Transfer otherwise complies with the terms of this Agreement and (ii) the Guaranty Agreement
executed and delivered by such Parent pursuant to Section 2.10 remains in full force and effect (and is applicable to such Transferee’s obligations) subsequent to such Transfer. 
 (b) Right of First Refusal. 
 (i) Subject to the right of first refusal set forth in this Section 3.6(b) and the other restrictions and
limitations contained herein, a Member may Transfer all, and not less than all, of its Membership Interest to another Person that is not a Wholly-Owned Affiliate of the Member’s Parent. 
 (ii) Except with respect to Transfers according to the terms of Section 3.6(a), any Member (or such Member’s
Affiliate) who receives, and desires to accept, a Qualifying Offer (such Member and any other Member deemed to have made a Transfer under Section 3.6(c) or 3.6(d), each a “Transferring Member”) from a
ready, willing and able Transferee shall first offer to transfer such Member’s Membership Interest (the “Subject Interest”) to the other Member (the “Non-Transferring Member”) no later than five
days following the decision by the Transferring Member to accept such Qualifying Offer. Such offer shall be made by an irrevocable written offer (the “Offer Notice”) to transfer all of the Subject Interest and shall contain a
complete description of the price and other terms and conditions of the transaction in which the Transferring Member proposes to Transfer the Subject Interest, including the name of the ready, willing and able Transferee, the consideration specified
and the proposed closing date of the transaction, which shall in no event be earlier than 30 days, or later than 60 days, following the expiration of the Option Period. The Non-Transferring Member shall have 30 days (the “Option
Period”) after receipt of the Offer Notice within which to advise the Transferring Member whether or not it will acquire the Subject Interest upon the terms and conditions contained in the Offer Notice. If, within the Option Period, the
Non-Transferring Member elects to acquire such Subject Interest, then such Non-Transferring Member shall close such transaction in accordance with this Section 3.6 no later than the closing date set forth in the Offer Notice.

 (iii) If the Non-Transferring Member declines to acquire all of the
Subject Interest of the Transferring Member in accordance with this Section 3.6(b), the Transferring Member may Transfer such Subject Interest to the Transferee named in the Offer Notice delivered to the Non-Transferring Member upon the
terms described in such Offer Notice. If such Transfer does not occur in accordance with the terms of such Offer Notice, such attempted Transfer shall be null and void ab initio and the Transferring Member shall again be subject to the
provisions of this Section 3.6(b). 
 (iv) Upon consummation of any such Transfer (whether to a
Member or any other Person), such Transferee and its Membership Interest shall automatically become a party to and be bound by this Agreement and shall thereafter have all of the rights and obligations of a Member hereunder. Notwithstanding the
foregoing, all Transfers pursuant to this Section 3.6(b) must also comply with and be governed by this Agreement, including any restrictions on Transfers herein and on any Transferee becoming a Substituted Member. 
 (c) Except as may be permitted under Section 4.3 or with prior Unanimous Consent, no Member may grant or suffer a
Security Interest on all or any portion of its Membership Interest or the equity interests of any Special Purpose Entity that is such Member or that Controls such Member (each, an “Encumbrance”). Except as permitted under
Section 4.3, if any Member (an “Encumbering Member”), without prior Unanimous Consent, should grant or suffer an Encumbrance, the Encumbering Member shall be obligated to notify the other Members in writing (and
such notice shall be the Offer Notice) and the Encumbrance shall be deemed to be a proposed Transfer of all the Membership Interests subject to the Encumbrance and, therefore, a Subject Interest offered to the other Members under
Section 3.6(b) at a price equal to the Fair Market Value of such Membership Interest and payable only in cash, and such Encumbering Member shall be obligated to sell its Membership Interest in accordance with Section 3.6(b)
and this Section 3.6(c). 
 (d) If a Member (i) undergoes a Change of Control, (ii) is
dissolved and wound up (unless the sole distributee of the Member’s Membership Interest is such Member’s Parent or a Wholly-Owned Affiliate of the Member’s Parent), or (iii) becomes a Bankrupt Member, or (iv) is an
Encumbering Member (as permitted under Section 3.6(c)) whose Membership Interests have been foreclosed upon by a creditor or trustee-in-bankruptcy in a legal or equitable proceeding, or (v) desires to sell its entire Membership
Interest as part of a larger transaction and the cash value of such Membership Interest cannot be readily ascertained, the affected Member shall be obligated to notify the other Member in writing (and such notice shall be deemed to be the Offer
Notice) and the entire Membership Interest owned by such Member shall be deemed to be the subject of a proposed Transfer and, therefore, a Subject Interest offered to the other Members under Section 3.6(b) at a price equal to the Fair
Market Value of such Membership Interest and payable only in cash, and such affected Member shall be obligated to sell its Membership Interest in accordance with Section 3.6(b) and this Section 3.6(d). 
 (e) Whenever the Fair Market Value of a Membership Interest is determined as a result of a deemed Transfer under
Sections 3.6(c) or 3.6(d), the Fair Market Value shall be determined as of the last day of the calendar month immediately preceding the occurrence of the Encumbrance, Change of Control or dissolution, foreclosure or bankruptcy, as
applicable, that is deemed a Transfer (the “Determination Date”); provided, however, that for purposes of determining the purchase price for the Subject Interest, the Fair Market Value shall be reduced by
any distributions made to the Transferring Member attributable to the Subject Interest, and increased by any Capital Contributions made by the Transferring Member attributable to the Subject Interest, occurring during the time period between the
Determination Date and the closing of the purchase and sale.

 (f) Whenever an option arises as a result of a deemed Transfer under
Section 3.6(c) or 3.6(d), the Option Period shall begin upon the occurrence of the event constituting the deemed Transfer and shall continue until the 30th day following the giving of the notification to the other Member
referenced in the applicable provision of Section 3.6(c) or 3.6(d). 
 (g) At the closing of
the Transfer of a Membership Interest pursuant to this Agreement, the Transferee shall deliver to the Transferring Member the full consideration agreed upon. Any membership interest transfer or similar taxes involved in such sale shall be paid by
the Transferring Member, and the Transferring Member shall provide the Transferee with such evidence of the Transferring Member’s authority to Transfer hereunder and such tax lien waivers and similar instruments as the Transferee may reasonably
request. 
 (h) If any governmental consent or approval is required with respect to any Transfer, the Transferee
shall have a reasonable amount of time (not to exceed 120 days from the date upon which such Transfer would have been otherwise consummated in accordance with the terms of this Agreement) to obtain such consent or approval. All Members shall use
reasonable, good faith efforts to cooperate with the Transferee attempting to obtain, and to assist in timely obtaining, such consent or approval; provided that no Member shall be required to incur any out-of-pocket costs or additional
liability in connection with such cooperation and assistance. After the expiration of such waiting period, such Transferee shall forfeit its rights to acquire the Subject Interest with respect to such specific transaction; provided,
however, that such forfeiture shall not limit or otherwise affect the forfeiting Transferee’s rights with respect to any subsequent proposed Transfer made in accordance herewith. 
 (i) No Transfer of a Membership Interest shall effect a release of the Transferring Member (or its applicable Affiliates)
from any liabilities or obligations to the Company or the other Member that accrued prior to the Transfer. 
 Section 3.7
Documentation; Validity of Transfer. The Company shall not recognize for any purpose any purported Transfer of a Membership Interest unless and until the applicable provisions of Sections 3.5 and 3.6 have been
satisfied and the Company has received, on behalf of the Company, a document in a form acceptable to the Company executed by both the Transferring Member (or if the Transfer is on account of the death, incapacity, or liquidation of the Member, its
representative) and the Transferee. Such document shall (a) include the notice address of the potential Transferee and such Person’s agreement to be bound by this Agreement with respect to the Membership Interest being obtained,
(b) contain a representation and warranty that the Transfer was made in accordance with all Laws (including state and federal securities Laws) and the terms and conditions of this Agreement, (c) include a legally binding agreement of the
Transferee to be bound by this Agreement from and after the date such Transferee becomes a Member and (d) if the Person to which the Membership Interest is Transferred is to be admitted to the Company as a Substituted Member, its representation
and warranty that the representations and warranties in Section 3.4 are true and correct with respect to such Person. Each Transfer and, if applicable, admission complying with the provisions of this Section 3.7 and
Sections 3.5, 3.6 and 3.9(b) is effective against the Company as of the first Business Day of the calendar month immediately succeeding the month in which (i) the Company receives the document required by this
Section 3.7 reflecting such Transfer, and (ii) the other requirements of Sections 3.5, 3.6 and 3.9(b) have been met. 
 Section 3.8 Possible Additional Restrictions on Transfer. Notwithstanding anything to the contrary contained in this Agreement, in the event of (a) the enactment (or imminent
enactment) of any legislation, (b) the publication of any temporary or final Regulations, (c) any ruling by the Service or (d) any judicial decision that in any such case, in the opinion of counsel to the Company, would result in the
taxation of the Company for federal income tax purposes as a corporation or would otherwise subject the Company to being taxed as an entity for federal income tax purposes, this Agreement shall be deemed to impose such restrictions on the Transfer
of a Membership Interest as may be required, in the opinion of

counsel to the Company, to prevent the Company from being taxed as a corporation or otherwise being taxed as an entity for federal income tax purposes, and the Members thereafter shall amend this
Agreement as necessary or appropriate to impose such restrictions. 
 Section 3.9 Substituted Members.

 (a) Persons, including Transferees, may be admitted to the Company as Substituted Members as provided under
the terms of this Section 3.9. Except as expressly provided otherwise, any Transferee with respect to a Transfer made in accordance with Section 3.6(a) or 3.6(b) shall be admitted automatically as a Substituted Member
upon compliance with Sections 3.5, 3.6, 3.7 and 3.9(b) with respect to such Transfer, but without the consent or approval of any other Person; provided, however, that any Transferee that is not
already a Member at the time of the Transfer and acquires a Membership Interest by foreclosure shall not be admitted as a Substituted Member without Unanimous Consent. 
 (b) Notwithstanding anything to the contrary contained herein, a Person may be admitted as a Substituted Member only if such
Person either meets the Credit Standards or delivers to the other Member a Guaranty Agreement from a Creditworthy Affiliate of such Person, as guarantor. This Section 3.9(b) shall not apply to Transferees under
Section 3.6(a). 
 (c) Upon becoming a Substituted Member, (i) such Substituted Member shall
have all of the powers, rights, privileges, duties, obligations and liabilities of a Member, as provided in this Agreement and by Laws to the extent of the Membership Interest so Transferred and (ii) the Member who Transferred the Membership
Interest and its guarantor (except as provided in Section 3.6(a)) shall be relieved of all of the obligations and liabilities with respect to such Membership Interest (and the Guaranty of such guarantor, except as provided in
Section 3.6(a), shall be deemed terminated with respect to such obligations and liabilities); provided that such Member and its guarantor shall remain fully liable for all liabilities and obligations relating to such Membership
Interest that accrued prior to the applicable Transfer (and the Guaranty of such guarantor shall remain in full force and effect with respect to such liabilities and obligations). 
 Section 3.10 Information. 
 (a) In addition to the other rights specifically set forth in this Agreement, each Member is entitled to all information to which that Member is entitled to have access pursuant to the Act under the
circumstances and subject to the conditions therein stated. 
 (b) The Members acknowledge that, from time to
time, they may receive information from or regarding the Company, any other Member or its Affiliates or their respective customers in the nature of trade secrets or secret or proprietary information or information that is otherwise confidential, the
release of which may be damaging to the Company, the Members or their Affiliates, as applicable, or Persons with which they do business. Each Member shall hold in strict confidence any such information it receives for a period of two years following
the termination of this Agreement and, during such time period, may not disclose such information to any Person other than another Member, except for disclosures (i) to comply with any Laws (including applicable stock exchange or quotation
system requirements), (ii) to Affiliates, advisers or representatives of the Member or Persons to which that Member’s Membership Interest may be Transferred as permitted by this Agreement, but only if the recipients of such information
have agreed to be bound by the provisions of this Section 3.10(b), (iii) of information that a Member also has received from a source independent of the Company and that such Member reasonably believes such source obtained without
breach of any obligation of confidentiality, (iv) of information obtained prior to the formation of the Company,

provided that this clause (iv) shall not relieve any Member or any of its Affiliates from any obligations it may have to any other Member or any of its Affiliates under any
existing confidentiality agreement, (v) to lenders, accountants, attorneys, financial advisors and other representatives of the disclosing Member with a need to know such information, provided that the disclosing Member shall be
responsible for such representatives’ use and disclosure of any such information, (vi) of public information, or (vii) in connection with any proposed Transfer of a Membership Interest of a Member or the proposed sale of all or
substantially all of the assets of a Member or its Parent, to advisers or representatives of the Member, its Parent or Persons to which such interest may be Transferred as permitted by this Agreement, but only if the recipients of such information
have agreed in writing to be bound by confidentiality provisions that are no less stringent than those set forth in this Section 3.10(b). The Members acknowledge that a breach of the provisions of this Section 3.10(b) may
cause irreparable injury to the Company or another Member for which monetary damages are inadequate, difficult to compute, or both. Accordingly, the Members agree that the provisions of this Section 3.10(b) may be enforced by injunctive
action or specific performance, and the Members hereby waive any requirement to post bond in connection with any injunctive order or order for specific performance. 
 (c) The Members acknowledge that, from time to time, the Company may need information from any or all of such Members for
various reasons, including for complying with various federal and state regulations. Each Member shall provide to the Company all information reasonably requested by the Company for purposes of complying with federal or state regulations, in each
case within a reasonable amount of time from the date such Member receives such request; provided, however, that no Member shall be obligated to provide such information to the Company to the extent such disclosure
(i) could reasonably be expected to result in the breach or violation of any contractual obligation (if a waiver of such restriction cannot reasonably be obtained) or Law or (ii) involves secret, confidential or proprietary information, in
which case any Member may provide such information directly to such federal or state regulatory authorities. 
 (d) Notwithstanding anything in this Section 3.10 to the contrary, a Member (and its Affiliates) may, in its independent pursuit of any Facility Opportunity that it is permitted to pursue under Section 2.9(b), use
and disclose to other Persons as may be required in connection therewith, any information regarding such Facility Opportunity, including information received from the Company or any other Member; provided, however, that such
Member may not provide confidential information about the Company or any other Member to any Person without first obtaining from such Person an executed confidentiality agreement with substantially similar provisions to those set forth in
Section 3.10(b) (except that the term of the obligations thereunder must extend only for a period equal to at least two years after the date of such agreement). 
 Section 3.11 Liability to Third Parties. Except as required by the Act, no Member shall be liable to any Person
(including any Third Party, the Company or to another Member) (a) as the result of any act or omission of another Member or (b) for Company losses, liabilities or obligations (except as otherwise expressly agreed to in writing by such
Member). 
 Section 3.12 No Resignation. A Member may not take any action to Resign voluntarily without the
prior written consent of all other Members. 
 Section 3.13 Fair Market Value. The “Fair Market
Value” of the Subject Interest deemed to be Transferred under Section 3.6(c) or 3.6(d) shall be determined by mutual agreement of the Transferring Member (or its representative) and the Non-Transferring Member;
provided, however, that if such Persons do not agree on the Fair Market Value of such Subject Interest during the first 20 days of the Option Period, then (a) either Member, by written notice to the other Member, may
require the determination of Fair Market Value to be made by an independent appraiser specified in such written

notice, and (b) the Option Period shall thereafter be extended until the 10th day following the final determination of Fair Market Value in accordance with the terms hereof. If the Member
receiving such notice objects, in writing, to the independent appraiser designated in such notice, on or before the 10th day following such Member’s receipt thereof, and the Members otherwise fail to agree on an independent appraiser, either
Member may request the CPR Institute to designate an independent appraiser who shall be qualified by his or her education, training and experience in the water processing and transportation industry to determine the Fair Market Value of such Subject
Interest, whose determination shall be final and binding on both Members. Failing designation by the CPR Institute, either Member may in writing request the judge of the United States District Court for the Northern District of Texas senior in term
of service to appoint an independent appraiser qualified by his or her education, training and experience in the water processing and transportation industry to determine the Fair Market Value of such Subject Interest, whose determination shall be
final and binding on all parties. If the independent appraiser so chosen shall die, resign or otherwise fail or becomes unable to serve as independent appraiser, a replacement independent appraiser shall be chosen in accordance with this
Section 3.13. The Company shall, and shall instruct the Operators to, provide the independent appraiser with all information and data reasonably necessary to make a determination of Fair Market Value, subject to a customary
confidentiality agreement. The independent appraiser shall report to the Members its determination of Fair Market Value within 30 days after appointment, and such determination shall be final and binding on both Members. The Transferring Member, on
the one hand, and the Non-Transferring Member, on the other hand, each shall pay one-half of the appraisal and court costs in appointing an appraiser.

 Section 4.2 Subsequent Contributions. 
 (a) Except as set forth in Section 4.2(b) or (c) or as may be approved by the Board by Unanimous
Consent, no Member shall be required to make any additional Capital Contribution. 
 (b) The Members agree to
contribute to the Company the sums required for the Company to pay all amounts necessary to fund (i) the Facility Plan for each Facility Opportunity that has received Unanimous Consent and is being pursued pursuant to Section 2.9(b)
and (ii) any other Capital Contribution approved by Unanimous Consent (in each case, a “Required Contribution”). Each Member agrees to contribute that portion of the Required Contribution equal to its Membership
Interest. Such contributions shall be made within 10 Business Days following the end of each such month pursuant to cash calls issued by the Managing Member when and in the amounts required to satisfy such Required Contribution. 
 (c) Each Consent Member shall be required to contribute to the Company the portion of the sums required to fund any Facility
Opportunity pursued by such Consent Member in accordance with Section 2.9(c) in accordance with the applicable Facility Plan (each, an “Facility Contribution”). Such Facility Contributions shall be made pursuant
to cash calls issued by the Managing Member (or any Member, if the Managing Member fails to issue any such cash call) when and in the amounts specified in the applicable Facility Plan related to such Facility Opportunity. The Company shall use the
proceeds of such Facility Contributions exclusively for the purposes of pursuing the Facility Opportunity to which such Facility Contribution relates in accordance with the applicable Facility Plan.

made by a non-Delinquent Member on behalf of a Delinquent Member shall constitute a loan to the Delinquent Member (the non-Delinquent Member making such loan, the “Lending Member,” whether one or more). Such advance shall
have the following results: 
 (i) the sum advanced shall constitute a loan from the Lending Member to the
Delinquent Member and a Capital Contribution of that sum to the Company by the Delinquent Member pursuant to the applicable provisions of this Agreement; 
 (ii) the principal balance of the loan and all accrued unpaid interest thereon (collectively, the “Obligation”) shall be due and payable in whole on the 10th Business Day after the
day written demand requesting payment of the Obligation is made by the Lending Member to the Delinquent Member; provided, however, that the Delinquent Member may prepay the Obligation in whole or in part at any time prior to the
date due; 
 (iii) the amount lent shall bear interest at the Default Interest Rate per annum, compounded
quarterly on the first day of each Quarter, from the date on which the advance is deemed made until the date that the Obligation and all costs and expenses associated therewith (“Costs”), is repaid to the Lending Member;

 (iv) all distributions from the Company that otherwise would be made to the Delinquent Member (whether before
or after dissolution of the Company) instead shall be paid to the Lending Member until the Obligation and any Costs have been paid in full to the Lending Member (with payments being applied first to accrued and unpaid interest, second to Costs, and
finally to principal); 
 (v) the Lending Member shall have the right, in addition to the other rights and
remedies granted to it pursuant to this Agreement or available to it at law or in equity, to take any action (including court proceedings and exercising the rights of a secured party under the Uniform Commercial Code of the State of Delaware or any
other appropriate state (the “UCC”)) that the Lending Member may deem appropriate to obtain payment from the Delinquent Member of the Obligation and all Costs; 
 (vi) if the Delinquent Member has defaulted on more than one Capital Contribution, the non-Delinquent Member that has made
advances on behalf of such Delinquent Member under this Section 4.3(a) shall have recourse to such Delinquent Member’s Membership Interest pursuant to Sections 4.3(a), 4.3(b) and 4.3(c) in priority based on
the order of the dates on which the Capital Contributions giving rise to such advances under this Section 4.3(a) were required to be made by the Delinquent Member, with an advance made in respect of Capital Contributions required at an
earlier date (and the Obligations and Costs relating to such advance) having priority over advances made in respect of Capital Contributions required at a later date (and the Obligations and Costs relating to such other advances); 
 (vii) the Delinquent Member deemed to have received a loan from a Lending Member under the terms of this
Section 4.3(a) shall continue to be deemed in Default until all Obligations and Costs under such loan have been paid and satisfied in full; and

 (viii) initially, a loan by a Member to another Member as contemplated
by this Section 4.3(a) shall not be considered a Capital Contribution by the Lending Member and shall not increase the Capital Account balance of the Lending Member. Notwithstanding the foregoing, in the event the Obligations under any
such loan have not been fully satisfied within 90 days from the date of the loan, the Lending Member, at any time thereafter by giving written notice to the Company, may elect to have the unpaid principal balance of such loan transferred to and
increase such Lending Member’s Capital Account with a corresponding decrease in the Capital Account of the Member on whose behalf such loan was made. Upon such transfer, the unpaid principal balance of such loan shall be treated as a Capital
Contribution, and the Membership Interest for each Member shall be automatically adjusted to equal the percentage obtained by dividing (A) the Capital Contributions of such Member (including any Capital Contribution made on behalf of the other
Member under this Section 4.3) by (B) the aggregate Capital Contributions of all Members (including all Capital Contributions made on behalf of the other Member under this Section 4.3); provided that the
adjustments to the Membership Interests provided in this subsection (viii) shall occur after adjustment of the Capital Accounts as provided in Section 4.5(d) as if additional Membership Interests were being issued. Upon the
adjustment of the Membership Interests in the manner set forth in the preceding sentence, Exhibit A shall be deemed to be amended to reflect such adjusted Membership Interests. If any interest or Costs remain unpaid in connection with
such loan at the time the Lending Member makes an election under this subsection, the Lending Member shall retain its rights and remedies for collection of interest and Costs in connection with such loan under this Section 4.3(a) with
respect to the Membership Interest, if any, of the Delinquent Member after adjustment pursuant to this subsection, but the amount treated as a Capital Contribution shall be deemed to have been repaid. 
 (b) Each Member grants to each Lending Member as security for any Obligations and Costs that may be due and owing by such
Member hereunder a security interest in its Membership Interest pursuant to and in accordance with the UCC and agrees that the Lending Member shall have the rights and remedies granted under the UCC with respect to the security interest granted
therein. Each Member authorizes any Lending Member to file UCC financing statements related thereto and agrees that this Agreement serves as the necessary security agreement. 
 (c) The Company or the non-Delinquent Member shall have the right to exercise the following remedies with respect to a
Delinquent Member in addition to the rights granted by Section 4.3(a): 
 (i) the Company or the
non-Delinquent Member may at any time take such action (including court proceedings) as the Company or the non-Delinquent Member may deem appropriate to obtain payment by the Delinquent Member of the portion of the Delinquent Member’s Capital
Contribution that is in Default, along with all costs and expenses associated with the collection of such Delinquent Member’s Capital Contribution; and 
 (ii) the Company or the non-Delinquent Member may at any time exercise any other rights and remedies available under this
Agreement or at law or in equity. 
 Section 4.4 Return of Contributions. A Member is not entitled
(a) to the return of any part of any Capital Contributions or (b) to be paid interest in respect of either its Capital Account or its Capital Contributions. An unrepaid Capital Contribution is not a liability of the Company or of any
Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return the other Member’s Capital Contributions.

 Section 4.5 Capital Accounts. The Company shall maintain for each
Member a separate Capital Account in accordance with the rules of Treasury Regulation section 1.704-1(b)(2)(iv) and in accordance with the following provisions: 
 (a) Each Member’s Capital Account shall be increased by (i) the amount of all Capital Contributions made to the
Company by such Member pursuant to this Agreement, (ii) all items of Company income and gain computed in accordance with Section 4.5(b) and allocated with respect to such Member pursuant to Section 5.1, and
(iii) the amount of any Company liabilities assumed by such Member or that are secured by any Company property distributed to such Member, and decreased by (A) the amount of cash or Net Agreed Value of property actually or deemed
distributed to such Member pursuant to this Agreement, (B) all items of Company deduction and loss computed in accordance with Section 4.5(b) and allocated to such Member pursuant to Section 5.1 and (C) the amount
of any liabilities of such Member assumed by the Company or that are secured by any property contributed by such Member to the Company. 
 (b) For purposes of computing the amount of any item of income, gain, loss or deduction which is to be allocated pursuant to Article V and is to be reflected in the Members’ Capital Accounts,
the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes, provided that: 
 (i) All fees and other expenses incurred by the Company to promote the sale of (or to sell) a Membership Interest that can
neither be deducted nor amortized under section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among
the Members pursuant to Section 5.1. 
 (ii) Except as otherwise provided in Treasury Regulation
section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under section 754 of the Code which may be made by the Company and, as to those items described in
section 705(a)(1)(A) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. 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 Treasury Regulation section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such
adjustment in the Capital Accounts shall be treated as an item of gain or loss. 
 (iii) Any income, gain or loss
attributable to the taxable disposition of any Company property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Company’s Carrying Value with respect to such property as
of such date. 
 (iv) In lieu of the depreciation, amortization and other cost recovery deductions taken into
account in computing such items, there shall be taken into account Depreciation, computed in accordance with the definition of “Depreciation.” 
 (v) For purposes of determining income, gain, loss, and deduction, or any other item allocable to any period, such items will be determined on a daily, monthly or other basis, as reasonably determined by
the Board using any permissible method under Code section 706 and the related Treasury Regulations.

 (c) A Transferee shall succeed to the pro rata portion of the Capital
Account of the transferor relating to the Membership Interest so transferred. Except as otherwise provided herein, all items of income, gain, expense, loss, deduction, and credit allocable to any Membership Interest that may have been transferred
during any calendar year shall, if permitted by law, be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as owning that Membership Interest, based upon the interim closing
of the books method; provided, however, that this allocation must be made in accordance with a method permissible under section 706 of the Code and the Treasury Regulations thereunder. 
 (d) (i) In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), on an issuance of additional Membership
Interests for cash or Contributed Property and the issuance of Membership Interests as consideration for the provision of services, the Capital Accounts of all Members and the Carrying Value of each Company property immediately prior to such
issuance or adjustment shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such
property immediately prior to such issuance or adjustment and had been allocated to the Members at such time pursuant to Section 5.1 in the same manner as any item of gain or loss actually recognized during such period would have been
allocated. In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and Fair Market Value of all Company assets (including cash and cash equivalents) immediately prior to the issuance of additional Membership Interests shall
be determined by the Board using such method of valuation as it may adopt. The Board shall allocate such aggregate value among the assets of the Company (in such manner as it determines) to arrive at a Fair Market Value for individual properties.

 (ii) In accordance with Treasury Regulation section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or
deemed distribution to a Member of any Company property (other than a distribution of cash that is not in redemption or retirement of a Membership Interest), the Capital Accounts of all Members and the Carrying Value of all Company property shall be
adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Company property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution
for an amount equal to its Fair Market Value, and had been allocated to the Members, at such time, pursuant to Section 5.1 in the same manner as any item of gain or loss actually recognized during such period would have been allocated.
In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and Fair Market Value of all Company assets (including cash and cash equivalents) immediately prior to a distribution shall (A) in the case of an actual
distribution that is not made pursuant to Section 10.2 or in the case of a deemed distribution, be determined and allocated in the same manner as that provided in Section 4.5(d)(i) or (B) in the case of a liquidating
distribution pursuant to Section 10.2, be determined and allocated by the Liquidator using such method of valuation as it may adopt.

 ALLOCATIONS AND DISTRIBUTIONS 
 Section 5.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in
determining the rights of the Members among themselves, the Company’s items of income, gain, loss and deduction (computed in accordance with Section 4.5(b)) shall be allocated among the Members in each taxable year (or portion
thereof) as provided herein below. 
 (a) Net Income and Net Loss. After giving effect to the special
allocations set forth in Sections 5.1(b) and (c), Net Income and Net Loss for each taxable period and all items of income, gain, loss and deduction taken into account in the computation thereof shall be allocated to the Members in
accordance with their respective Membership Interests.

 (b) Consent Member Facility Net Income and Consent Member Facility
Net Loss. Consent Member Facility Net Income and Consent Member Facility Net Loss shall be allocated among the Members as set forth in this Section 5.1(b). This Section 5.1(b) shall be applied separately for each Consent
Member Facility Opportunity. 
 (i) Consent Member Facility Net Income for any taxable year shall be allocated:

 (A) First, to the Consent Member until the cumulative Consent Member Facility Net Income allocated with
respect to the current and all prior taxable periods equals the cumulative Consent Member Facility Net Losses, if any, allocated pursuant to Section 5.1(b)(ii)(B) during all prior taxable periods, plus the amount described in clause
(b) of the definition of Earn-Out Period with respect to the applicable Consent Member Facility Opportunity; and 
 (B) Thereafter, to the Members in accordance with their respective Membership Interests. 
 (ii) Consent Member Facility Net Loss for any taxable year shall be allocated: 
 (A) First, to the Members in accordance with their respective Membership Interests until the cumulative Consent Member Facility Net Losses allocated with respect to the current and all prior taxable
periods equal the cumulative Consent Member Facility Net Income, if any, allocated pursuant to Section 5.1(b)(i)(B) during all prior taxable periods; and 
 (B) Thereafter, to the Consent Member. 
 (c) Special Allocations. Notwithstanding any other provision of this Section 5.1, the following special
allocations shall be made for such taxable period in the following order and priority: 
 (i) Company Minimum
Gain Chargeback. Notwithstanding the other provisions of this Section 5.1, if there is a net decrease in Company Minimum Gain during any Company taxable period, each Member shall be allocated items of Company income and gain for such
taxable period (and, if necessary, subsequent taxable periods) in the manner and amounts provided in Treasury Regulation sections 1.704-2(f)(6) and (g)(2) and section 1.704-2(j)(2)(i), or any successor provisions. For purposes of this
Section 5.1(c), each Member’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this
Section 5.1(c) with respect to such taxable period (other than an allocation pursuant to Section 5.1(c)(v) and 5.1(c)(vi). This Section 5.1(c)(i) is intended to comply with the Company Minimum Gain
chargeback requirement in Treasury Regulation section 1.704-2(f) and shall be interpreted consistently therewith. 
 (ii) Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt. Notwithstanding the other provisions of this Section 5.1 (other than Section 5.1(c)(i)), except as provided in Treasury Regulation
section 1.704-2(i)(4), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Company taxable period, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated
items of Company income and gain for such taxable period (and, if necessary, subsequent taxable periods) in the

manner and amounts provided in Treasury Regulation sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 5.1(c), each Member’s
Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 5.1(c), other than
Section 5.1(c)(i) and other than an allocation pursuant to Section 5.1(c)(vi) and 5.1(c)(vii), with respect to such taxable period. This Section 5.1(c)(ii) is intended to comply with the chargeback of items
of income and gain requirement in Treasury Regulation section 1.704-2(i)(4) and shall be interpreted consistently therewith. 
 (iii) Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation section 1.704-1(b)(2)(ii)(d)(4)
through (6), items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under section 704(b) of the Code, the deficit
balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided that, an allocation pursuant to this Section 5.1(c)(iii) shall be made only if and to the
extent that such Member would have a deficit in such Member’s Adjusted Capital Account after all other allocations provided in this Article V have been tentatively made as if this Section 5.1(c)(iii) were not a part of this
Agreement. This Section 5.1(c)(iii) is intended to be a “qualified income offset” as that term is used in Treasury Regulation section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. 
 (iv) Stop Loss. No amount of Net Loss shall be allocated pursuant to Section 5.1(a) to the extent that
such allocation would cause any Member to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account). All Net Losses in excess of the limitation
set forth in the preceding sentence shall be allocated among such other Members, who have positive Adjusted Capital Account balances, in proportion to their respective Membership Interests until each Member’s Adjusted Capital Account balance is
reduced to zero. Thereafter, any remaining Net Loss shall be allocated to the Members in proportion to their relative interests in the Company as required by section 704(b) of the Code. 
 (v) Gross Income Allocations. In the event any Member has a deficit balance in its Adjusted Capital Account at the end
of any Company taxable period in excess of the sum of (A) the amount such Member is obligated to restore pursuant to any provision of this Agreement and (B) the amount such Member is deemed obligated to restore pursuant to Treasury
Regulations sections 1.704-2(g) and 1.704-2(i)(5), such Member shall be specially allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided that, an allocation pursuant to this
Section 5.1(c)(v) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 5.1 have been tentatively made as if
this Section 5.1(c)(v) were not in the Agreement. 
 (vi) Nonrecourse Deductions. Nonrecourse
Deductions for any taxable period shall be allocated to the Members in accordance with their respective Membership Interests. If the Board determines that the Company’s Nonrecourse Deductions should be allocated in a different ratio to satisfy
the safe harbor requirements of the Treasury Regulations promulgated under section 704(b) of the Code, the Board is authorized, upon notice to the Members, to revise the prescribed ratio to the numerically closest ratio which does satisfy such
requirements. 
 (vii) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable period
shall be allocated 100% to the Member that bears the Economic Risk of Loss with respect to such Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation section 1.704-2(i). If more
than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, such Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Members in accordance with the ratios in which they share
such Economic Risk of Loss.

 (viii) Nonrecourse Liabilities. For purposes of Treasury
Regulation section 1.752-3(a)(3), the Members agree that Nonrecourse Liabilities of the Company in excess of the sum of (A) the amount of Company Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated
among the Members in accordance with their respective Membership Interests. 
 (ix) 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 Treasury Regulation section 1.704-1(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 Treasury Regulations. 
 (x) Curative Allocation. Notwithstanding any other provision of this Section 5.1, other than the Required
Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss or deduction allocated to each Member pursuant to the Required
Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Member under the Agreed Allocations had the Required Allocations and the related Curative Allocations not
otherwise been provided in this Section 5.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecouse Deductions shall not be taken into account except to the extent that there has been a decrease in
Company Minimum Gain and (2) Member Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Member Nonrecourse Debt Minimum Gain. Allocations pursuant to this Section 5.1(c)(x)
shall only be made with respect to Required Allocations to the extent the Board reasonably determines that such allocations will otherwise be inconsistent with the economic agreement among the Members. Further, allocations pursuant to this
Section 5.1(c)(x) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the Board determines that such allocations are likely to be offset by subsequent Required
Allocations. 
 Section 5.2 Allocations for Tax Purposes. 
 (a) Except as otherwise provided herein, 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 5.1. 
 (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of
income, gain, loss, depreciation, amortization and cost recovery deductions 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 in
the manner provided under section 704(c) of the Code that takes into account the variation between the Agreed Value of such property and its adjusted basis at the time of contribution; 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 5.1.

 (ii) (A) In the case of an Adjusted Property, such items shall
(1) 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 4.5(d)(i) or 4.5(d)(ii), and (2) second, in the event such property was originally a Contributed Property, be allocated among the Members in a manner consistent with Section 5.2(b)(i)(A); and (B) any
item of Residual Gain or Residual Loss attributable to an Adjusted 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 5.1.

 (iii) The Board shall apply the principles of Treasury Regulation section 1.704-3(d) to eliminate Book-Tax
Disparities. 
 (c) For the proper administration of the Company, the Board shall (i) adopt such conventions
as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (ii) make special allocations for federal income tax purposes of income (including gross income) or deductions; and (iii) amend
the provisions of this Agreement as appropriate to reflect the proposal or promulgation of Treasury Regulations under section 704(b) or section 704(c) of the Code. The Board may adopt such conventions, make such allocations and make such amendments
to this Agreement as provided in this Section 5.2(c) only if such conventions, allocations or amendments are consistent with the principles of section 704 of the Code and would not have a material adverse effect on the Members.

 (d) Any gain allocated to the Members upon the sale or other taxable disposition of any Company asset shall,
to the extent possible, after taking into account other required allocations of gain pursuant to this Section 5.2, be characterized as Recapture Income in the same proportions and the same extent as such Members (or their predecessors in
interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income. 
 (e) All items of income, gain, loss, deduction and credit recognized by the Company for federal income tax purposes and allocated to the Members in accordance with the provisions hereof shall be
determined without regard to the election under section 754 of the Code that will be made by the Company; provided, however, that such allocations, once made, shall be adjusted (in any manner determined by the Board) as
necessary or appropriate to take into account those adjustments permitted or required by sections 734 and 743 of the Code. 
 Section 5.3 Transfer of Interest. In the event of a Transfer of all of a Membership Interest of a Member (in accordance with the provisions of this Agreement) at any time other than the end of a Fiscal Year, the shares
of items of Net Income or Net Loss and specially allocated items allocable to the Membership Interest transferred shall be allocated between the Transferring Member and the Transferee in a manner determined by the Board in its discretion that is not
inconsistent with the applicable provisions of the Code and Regulations. 
 Section 5.4 Requirement of
Distributions. 
 (a) Within 30 Business Days following the end of each Quarter, (i) an amount equal
to 100% of Available Cash from Operations shall, be distributed by the Company to the Members in accordance with the Membership Interests, and (ii) all Net Incremental Revenues attributable to any Consent Member Facility Opportunities (but only
during the Earn-Out Period associated therewith) shall be distributed in accordance with Section 2.9(c). All distributions required to be made under this Agreement shall be made subject to Sections 18-607 and 18-804 of the Act, as
applicable.

dissolution and liquidation of the Company, all receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of,

 MANAGEMENT OF THE COMPANY 
 Section 6.1 Generally. The management of the Company is fully vested in the Members, acting exclusively in their
membership capacities; provided, however, that ETC Member will serve as the Managing Member of the Company with full power and authority to manage the business and affairs of the Company, except that Major Decisions will be
subject to approval of the Board as described in Section 6.3. The Managing Member shall constitute a “manager,” as the term is used in the Act, but neither any Officer nor any employee or agent of the Company, if any, or the
other Members shall constitute “managers.” Except as otherwise provided in this Agreement, decisions or actions taken by the Managing Member in accordance with the provisions of this Agreement shall constitute decisions or actions by the
Company and shall be binding on each Member and the Company. Except as provided otherwise in this Agreement or as required by Law, all decisions respecting any matter set forth herein or otherwise relating to or arising out of the business of the
Company shall be made by the Managing Member, and the Managing Member shall have the exclusive right and full authority to manage, conduct and control the business of the Company consistent with the purposes of the Company but in all events subject
to the provisions of this Agreement. Any Person dealing with the Company, other than a Member or a Member’s Affiliate, may rely on the authority of the Managing Member, the Board or the Officers in taking any action in the name of the Company
without inquiry into the provisions of this Agreement or compliance with it, regardless of whether that action actually is taken in accordance with the provisions of this Agreement. No Officer or Member, except as may be within the Board’s
designation of authority, if any, to such Officer or the Managing Member, shall have any unilateral right or authority to take any action on behalf of the Company or to bind or commit the Company to any agreements, transactions or other arrangements
with respect to Third Parties or otherwise or to hold itself out as an agent of the Company. Except as otherwise expressly provided in this Agreement, each Member hereby (a) specifically delegates to the Managing Member and the Board its rights

manner and in an amount equal to 110% of the corresponding amount budgeted for the prior Calendar Year (but otherwise such disputed item shall not be deemed included in the next Calendar Year’s Budget). Upon the resolution of any disputed items
by the Board, the Budget, as amended to include the applicable item or items, as resolved, shall be considered approved by the Board. 
 (e) If, (i) at any time, the Managing Member receives an AFE Request from an Operator pursuant to such Operator’s O&R Agreement, or (ii) during the period covered by an approved Budget,

lawfully called or convened). Written notice of meetings of the Board, including the purpose of the meeting, shall be given to each Board Member (and each Alternate Board Member) with the notice of the meeting. Any Board Member may waive notice of
any meeting by the execution of a written waiver prior or subsequent to such meeting. The attendance of a Board Member at any meeting shall constitute a waiver of notice of such meeting, except where a Board Member attends a meeting for the express
purpose of objecting to the transaction of any business on the grounds that the meeting was not lawfully called or convened. Neither the business to be transacted at, nor the purpose of any regular or special meeting of the Board, need be specified
in a waiver of notice of such meeting.

the Board. The Company’s Secretary shall act as the secretary of the meeting who shall make a written record of the proceedings of such meeting and shall be provided to the Members promptly after the meeting. Initially, and subsequently on an

Board Member, as applicable, by the Member who was represented by such Board Member or Alternate Board Member. The appointment of a new Board Member or Alternate Board Member, as applicable, by a Member is effective upon receipt of notice thereof by

Member may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request consent, order, bond, debenture, or other paper or document believed by it to be
genuine and to have been signed or presented by the Board. The Board may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it and any act taken or omitted
in reliance upon the opinion of such Persons as to matters that the Board Members reasonably believe to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in
accordance with such opinion. No Board Member shall have any fiduciary or quasi-fiduciary duty to the Company or the Members pursuant to this Agreement and any standard of care and duty otherwise imposed on any Board Member by this Agreement or
under the Act or any Law shall be eliminated to the fullest extent permitted by the Act and by Law.

Contract”). With respect to any such Affiliate Contract: 
 (a) the Company shall enter into any
such contract (other than the O&R Agreements, which are hereby expressly approved pursuant to this Section 6.10) only with the approval of the Board, and the negotiation of any such Affiliate Contract shall be conducted on behalf of
the Company by or under the direction of the Board Members of only that Member that is not itself, nor are its Affiliates, to be a party to such Affiliate Contract; 
 (b) if the Affiliate that is party to any such contract is not the Parent of such Member, such Member’s Parent shall

 ARTICLE VII 
 LIMITATION OF LIABILITY AND
INDEMNIFICATION 
 Section 7.1 Limitation of Liability and Indemnification of Managing Member. In
addition to the provisions set forth in Section 2.8, to the fullest extent permitted under applicable Law, the Managing Member shall not be liable to the Company or any Member for any acts or omissions of the Managing Member (whether as
a result of the Managing Member’s ordinary negligence or otherwise) in the management of the Company (the “Managing Member Indemnified Acts”); provided that notwithstanding anything in this Agreement to the
contrary, the Managing Member shall be responsible to the Company with respect to its management of the Company to the extent that its acts or omissions constitute gross negligence or willful misconduct. The Company shall indemnify, protect, defend,
release and hold harmless the Managing Member and its Affiliates and each of their respective officers, directors, employees, representatives, attorneys and agents from and against any claims asserted by or on behalf of any Person (including the
other Members) that arise out of, relate to or are otherwise attributable to, directly or indirectly, the Managing Member Indemnified Acts. 
 Section 7.2 Right to Indemnification. Subject to the limitations and conditions as provided herein or by Laws, each Person who was or is made a party or is threatened to be made a
party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (hereinafter, a “Proceeding”), or any appeal in such a
Proceeding or any inquiry or investigation that could lead to such a Proceeding, by reason of the fact that he or she, or a Person of whom he or she is the legal representative, is or was a Member of the Company, a Board Member, a member of a
committee of the Board, or an Officer of the Company, or while such a Person is or was serving at the request of the Company as a director, officer, partner, venturer, member, trustee, employee, agent or similar functionary of another foreign or
domestic general partnership, corporation, limited partnership, joint venture, limited liability company, trust, employee benefit plan or other enterprise, shall be indemnified by the Company to the extent such Proceeding or other above-described

or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than the Act or said Laws
permitted the Company to provide prior to such amendment), against judgments, penalties (including excise and similar taxes and punitive damages), fines, settlements and reasonable expenses (including attorneys’ and experts’ fees) actually
incurred by such Person in connection with such Proceeding, and indemnification under this Article VII shall continue as to a Person who has ceased to serve in the capacity that initially entitled such Person to indemnity hereunder for
any and all liabilities and damages related to and arising from such Person’s activities while acting in such capacity; provided, however, that no Person shall be entitled to indemnification under this
Section 7.2 in the event the Proceeding involves acts or omissions of such Person which constitute an intentional breach of this Agreement or gross negligence or willful misconduct on the part of such Person. The rights granted pursuant
to this Article VII shall be deemed contract rights, and no amendment, modification or repeal of this Article VII shall have the effect of limiting or denying any such rights with respect to actions taken or Proceedings
arising prior to any such amendment, modification or repeal. It is expressly acknowledged that the indemnification provided in this Article VII could involve indemnification for negligence or under theories of strict liability.

 Section 7.3 Indemnification of Employees and Agents. The Company may indemnify, and advance expenses to,
Persons who are or were not covered by the indemnification in Section 7.1 or 7.2 above, including employees (if any) or agents of the Company or the Managing Member.

limited right to be paid or reimbursed by the Company for any and all reasonable expenses as they are incurred by a Person entitled to be indemnified under Section 7.1, 7.2 or 7.3 who was, or is threatened, to be made a
named defendant or respondent in a Proceeding in advance of the final disposition of the Proceeding and without any determination as to such Person’s ultimate entitlement to indemnification; provided, however, that the
payment of such expenses incurred by any such Person in advance of final disposition of a Proceeding shall be made only upon delivery to the Company of a written affirmation by such Person of his good faith belief that he has met the requirements
necessary for indemnification under this Article VII and a written undertaking, by or on behalf of such Person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified Person is not entitled to be
indemnified under this Article VII or otherwise. 
 Section 7.5 Appearance as a Witness.
Notwithstanding any other provision of this Article VII, the Company may pay or reimburse expenses incurred by any Person entitled to be indemnified pursuant to this Article VII in connection with such Person’s
appearance as a witness or other participation in a Proceeding at a time when he is not a named defendant or respondent in the Proceeding. 
 Section 7.6 Nonexclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in this Article VII shall not be exclusive of any
other right which a Person indemnified pursuant to Section 7.1, 7.2 or 7.3 may have or hereafter acquire under any Laws, this Agreement, or any other agreement, vote of the Members, the Board or otherwise. 
 Section 7.7 Insurance. The Company may, in accordance with Section 6.12, purchase and maintain
indemnification insurance, at its expense, to protect itself and any other Persons from any expenses, liabilities, or losses that may be indemnified under this Article VII.

 Section 7.9 Savings Clause. If this Article VII or any
portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify and hold harmless any Person entitled to be indemnified pursuant to this Article VII as to costs,
charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any
applicable portion of this Article VII that shall not have been invalidated and to the fullest extent permitted by Laws. 
 Section 7.10 Scope of Indemnity. For the purposes of this Article VII, references to the “Company” include all constituent entities, whether corporations or otherwise, absorbed in a consolidation
or merger as well as the resulting or surviving entity. Thus, any Person entitled to be indemnified or receive advances under this Article VII shall stand in the same position under the provisions of this Article VII with

 ARTICLE X 
 DISSOLUTION, LIQUIDATION, AND TERMINATION 
 Section
10.1 Dissolution. Subject to the provisions of Section 10.2 and any Laws, the Company shall dissolve and its affairs shall be wound up only on the first to occur of the following (each a “Liquidating
Event”): 
 (a) approval of the Board Members by Unanimous Consent; 
 (b) entry of a decree of judicial dissolution of the Company under section 18-802 of the Act; or 
 (c) the occurrence of any event that requires dissolution of a limited liability company under the Act. 
 Section 10.2 Liquidation and Termination. Subject to Section 10.2(d), upon dissolution of the Company, the
Managing Member shall act as a liquidator or may appoint one or more Members as liquidator (the “Liquidator”). The Liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as
provided herein and in the Act. The costs of liquidation shall be borne by the Company. Until final distribution, the Liquidator shall continue to operate the Company properties for a reasonable period of time to allow for the sale of all or a part
of the assets thereof with all of the power and authority of the Members and the Operators. The steps to be accomplished by the Liquidator are as follows: 
 (a) As promptly as possible after dissolution and again after final liquidation, the Liquidator shall cause a proper accounting to be made of the Company’s assets, liabilities, and operations through
the last day of the calendar month in which the dissolution occurs or the final liquidation is completed, as applicable. 
 (b) The Liquidator shall cause any notices required by Law to be mailed to each known creditor of and claimant against the Company in the manner described by such Law. 
 (c) Upon dissolution of the Company, and subject to Section 10.2(d) below, the Liquidator shall sell the assets
of the Company at the best price available. The property of the Company shall be liquidated as promptly as is consistent with obtaining the fair value thereof. The Liquidator may sell any or all Company property, including to one or more of the
Members (other than any Member in Default at the time of dissolution), provided that any such sale to a Member must be made on an arm’s length basis under terms which are in the best interest of the Company. If any assets are sold or
otherwise liquidated for value, the Liquidator shall proceed as promptly as practicable in a commercially reasonable manner to implement the procedures of this Section 10.2(c). 
 (d) Subject to the terms and conditions of this Agreement and the Act (especially Section 18-804), the Liquidator shall
distribute the assets of the Company in the following order of priority: 
 (i) first, to creditors of the
Company (including creditors who are Members) in satisfaction of the liabilities of the Company, including any accrued liabilities arising under the Affiliate Contracts (whether by payment or the making of reasonable provision for payment thereof);
and

 (ii) second, remaining amounts, if any, shall be distributed to the
Members in accordance with their respective positive Capital Account balances, as determined after taking into account all Capital Account adjustments for the taxable year of the Company during which the liquidation of the Company occurs.

 The Liquidator shall determine whether any assets of the Company shall be liquidated through sale or shall be
distributed in kind. A distribution in kind of an asset to a Member shall be considered, for the purposes of this Article X, a distribution in an amount equal to the fair market value of the assets so distributed as determined in good
faith by the Liquidator in its reasonable discretion. 
 Section 10.3 Provision for Contingent Claims. 

(a) The Liquidator shall make a reasonable provision to pay all claims and obligations, including all contingent,
conditional or unmatured claims and obligations, actually known to the Company but for which the identity of the claimant is unknown; and 
 (b) If there are insufficient assets to both pay the creditors pursuant to Section 10.2 and to establish the provision contemplated by Section 10.3(a), the claims shall be paid as
provided for in accordance to their priority, and, among claims of equal priority, ratably to the extent of assets therefor. 
 Section 10.4 Deficit Capital Accounts. No Member shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Company. 
 Section 10.5 Deemed Contribution and Distribution. In the event the Company is “liquidated” within the
meaning of Treasury Regulation section 1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Company’s property shall not be liquidated, the Company’s liabilities shall not be paid or discharged, and the Company’s affairs
shall not be wound up. Instead, solely for federal income tax purposes, the Company shall be deemed to have contributed all Company property and liabilities to a new limited liability company in exchange for an interest in such new limited liability
company and, immediately thereafter, the Company will be deemed to liquidate by distributing interests in the new limited liability company to the Members. 
 ARTICLE XI 
 AMENDMENT OF THE AGREEMENT 
 Section 11.1 Amendments to be Adopted by the Company. Each Member agrees that the Managing Member, in accordance with
and subject to the limitations contained in Article VI, may execute, swear to, acknowledge, deliver, file and record whatever documents may be required to reflect: 
 (a) a change in the name of the Company, the location of the principal place of business of the Company or the registered
agent or office of the Company; 
 (b) admission or substitution of Members whose admission or substitution has
been made in accordance with this Agreement; 
 (c) a change that the Managing Member believes is reasonable and
necessary or appropriate to qualify or continue the qualification of the Company as a limited liability company under the Laws of any state or that is necessary or advisable in the opinion of counsel for the Company to ensure that the Company will
not be taxable as a corporation or otherwise taxed as an entity for federal income tax purposes; and

 (d) an amendment that is necessary, in the opinion of counsel, to
prevent the Company, the Managing Member, the Board Members or the Officers from in any manner being subjected to the provisions of the Investment Company Act of 1940, as amended. 
 Section 11.2 Amendment Procedures. Except as provided in Section 11.1, all amendments to this Agreement
must be in writing and signed by all of the Members. 
 ARTICLE XII 
 MEMBERSHIP INTERESTS 
 Section 12.1 Certificates. Membership Interests will not be certificated unless otherwise approved by, and subject to the provisions set by, the Board. 
 Section 12.2 Registered Holders. The Company shall be entitled to recognize the exclusive right of a Person registered
on its books as the owner of the indicated Membership Interest and shall not be bound to recognize any equitable or other claim to or interest in such Membership Interest on the part of any Person other than such registered owner, whether or not it
shall have express or other notice thereof, except as otherwise provided by Law. 
 Section 12.3 Security.
For purposes of providing for Transfer of, perfecting a Security Interest in, and other relevant matters related to, a Membership Interest, to the extent permitted by this Agreement, the Membership Interest will be deemed to be a
“security” subject to the rules set forth in Chapters 8 and 9 of the UCC and any similar UCC provision adopted by any other relevant jurisdiction. 
 ARTICLE XIII 
 GENERAL PROVISIONS 
 Section 13.1 Entire Agreement; Supersedure. This Agreement constitutes the entire agreement and supersedes (a) all
prior oral or written proposals or agreements, (b) all contemporaneous oral proposals or agreements and (c) all previous negotiations and all other communications or understandings between the Members with respect to the subject matter
hereof, but excluding the O&R Agreements. 
 Section 13.2 Waivers. Neither action taken (including any
investigation by or on behalf of any party) nor inaction pursuant to this Agreement, shall be deemed to constitute a waiver of compliance with any representation, warranty, covenant or agreement contained herein by the party not committing such
action or inaction. A waiver by any party of a particular right, including breach of any provision of this Agreement, shall not operate or be construed as a subsequent waiver of that same right or a waiver of any other right. 
 Section 13.3 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Members and their
respective heirs, legal representatives, successors and permitted assigns. 
 Section 13.4 Board Deadlocks.
If any matter or proposal requiring Unanimous Consent for approval thereof with regard to the Company is brought before the Board and is not approved (a “Deadlock”), then any Board Member, by giving written notice containing
a brief description of the nature of the dispute and the position of the Board Member providing such notice to the other Board Members, may declare an impasse to be further negotiated. Within 10 Business Days after receipt of a notice of an impasse
notice, the chief executive officer or president of each Parent, or such Person’s designee (each, an “Executive Officer”) of the Members shall meet in a good faith effort to reach accords that will end the impasse
regarding the Deadlock. Unless otherwise agreed following such meetings, the matter that is the subject of the Deadlock shall be deemed disapproved and any action contemplated thereby shall not be taken.

 Section 13.5 Governing Law; Venue. 
 (a) THIS AGREEMENT HAS BEEN EXECUTED AND DELIVERED AND SHALL BE CONSTRUED, INTERPRETED AND GOVERNED PURSUANT TO AND IN
ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO ANY CONFLICT OF LAWS PRINCIPLES WHICH, IF APPLIED, MIGHT PERMIT OR REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. 
 (b) The Members hereby irrevocably submit to the exclusive jurisdiction of the courts located in Dallas County, Texas, and
the federal courts located in the Northern District of Texas, and appropriate appellate courts thereof, over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each Member hereby irrevocably
agrees that all claims in respect of such dispute or proceeding may be heard and determined by such courts. The Members hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have
to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each Member hereto
agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for the purposes of this Agreement and is not
intended to, and shall not, confer consent to jurisdiction with respect to any other dispute in which a Member may become involved. Each of the Members hereby consents to process being served by any other Member in any suit, action or proceeding of
the nature specified in this Section 13.5(b) by the mailing of a copy thereof in the manner specified by the provisions of Section 13.12. EACH OF THE MEMBERS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT. 
 Section 13.6 Further
Assurances. Subject to the terms and conditions set forth in this Agreement, each of the Members agree to use all reasonable efforts to take, or to cause to be taken, all actions, and to do, or to cause to be done, all things necessary,
proper or advisable under Laws and regulations to consummate and make effective the transactions contemplated by this Agreement. In case, at any time after the execution of this Agreement, any further action is necessary or desirable to carry out
its purposes, the proper officers or directors of the Members shall take or cause to be taken all such necessary action. 
 Section 13.7 Notice to Members of Provisions of this Agreement. By executing this Agreement, each Member acknowledges that it has actual notice of all of the provisions of this Agreement. Each Member hereby agrees that
this Agreement constitutes adequate notice of all such provisions. 
 Section 13.8 Counterparts. This
Agreement may be executed in multiple counterparts, each of which, when executed, shall be deemed an original, and all of which shall constitute but one and the same instrument.

 Section 13.10 Audit Rights of Members. 
 (a) Each Member shall have the right to inspect and audit (i) the books and records of the Company no more frequently
than once every 12 months and (ii) with respect to any other Member that has submitted an invoice for reimbursement pursuant to Section 2.11 hereof, the books and records of such other Member to the extent such books and records are
reasonably necessary to determine that the invoiced amount is not greater than the amount permitted for reimbursement under Section 2.11, as applicable. Such audits shall be conducted at the cost of the Member requesting same. The audit
rights with respect to any Calendar Year shall terminate on and as of the last day of the second Calendar Year immediately following the Calendar Year in question. A Member may exercise its audit rights hereunder by giving at least 30 days written
notice to the Company or the other Member, as applicable, of the desire to perform such audit, which notice shall include the estimated timing and other particulars related to such audit. The audit shall be conducted during normal business hours of
the Company or the other Member, as applicable. The audit shall not unreasonably interfere with the operation of the Company or the other Member, as applicable. 
 (b) Any Member shall have the right to cause the Company or a Subsidiary of the Company to exercise its inspection and audit
rights, if any, under the O&R Agreements. The costs related thereto shall be paid by the Member requesting same. 
 Section 13.11 No Third Party Beneficiaries. The provisions of this Agreement are for the exclusive benefit of the Members and their respective successors and permitted assigns and, solely with respect to Article
VII, the Persons entitled to be indemnified as described therein. Except for the foregoing, this Agreement is not intended to benefit or create rights in any other Person or Governmental Entity, including (a) any Person or Governmental
Entity to whom any debts, liabilities or obligations are owed by the Company or any Member or (b) any liquidator, trustee or creditor acting on behalf of the Company, and no such creditor or any other Person or Governmental Entity shall have

 Section 13.13 Remedies. 
 (a) Remedy Upon Event of Default. For so long as a Member is in Default, the rights, but not obligations, of such
Member hereunder, including the right to vote and receive distributions from the Company pursuant to Article V, shall be suspended; provided, however, that subject to the application of
Section 4.3(a)(iv), any distributions that would have been paid by the Company to such Member except for the application of this Section 13.13 shall be deposited by the Company into an interest-bearing account owned and
controlled by the Company, and upon (i) such Member no longer being in Default and (ii) if applicable, the final resolution of any dispute between the Company and such Member related to any Default, the funds held in such account shall be
distributed as follows: (A) if and to the extent applicable, on behalf of such Member to the Company to satisfy any obligations owed by such Member to the Company and (B) with respect to any funds remaining after the distribution required
under subparagraph (A), to such Member. With respect to any Default that cannot reasonably be cured by action of the defaulting Member, such Default shall not be deemed to be continuing after the defaulting Member has (i) entered into
and satisfied its obligations under a binding settlement with the Company related to such Default or (ii) satisfied its obligations arising from arbitration or any judicial proceeding related to such Default. 
 (b) Remedy Not Exclusive. The rights of the non-Defaulting Members set forth in Section 4.3 and this
Section 13.13 shall be in addition to such other rights and remedies that may exist at law, in equity or under contract on account of such Default. Without limiting the generality of the foregoing, the Members acknowledge that an award
of damages for failure to comply with Sections 2.9, 3.5, 3.6, 3.10, 13.4 and 13.15 would not be an adequate remedy for the Members attempting to enforce such provisions, and accordingly the Members
expressly authorize any such Members to bring an action against the other Member to compel the specific performance by such other Members of their obligations to comply with such provisions, including, in the case of a breach of
Section 2.9, disgorgement to the Company of any Facility Opportunity acquired by a Member outside of the Company and in violation of this Agreement. 
 (c) Except as expressly provided herein, the rights, obligations and remedies created by this Agreement are cumulative and in
addition to any other rights, obligations or remedies otherwise available at law or in equity. Nothing herein shall be considered an election of remedies. In addition, any successful party is entitled to costs related to enforcing this Agreement,
including, without limitation, attorneys’ fees, and arbitration expenses. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, THE MEMBERS AND THE COMPANY WAIVE ANY AND ALL

RIGHTS, CLAIMS OR CAUSES OF ACTION AGAINST ONE ANOTHER ARISING UNDER THIS AGREEMENT FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES AND LOST PROFITS, WHETHER
BASED ON CONTRACT, TORT, STRICT LIABILITY OR OTHERWISE AND WHETHER OR NOT ARISING FROM SUCH PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT. A PARTY MAY RECOVER FROM ANY OTHER PARTY ALL COSTS, EXPENSES OR DAMAGES,
INCLUDING INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE, EXEMPLARY DAMAGES AND LOST PROFITS AND OTHER DAMAGES PAID OR OWED TO ANY THIRD PERSON FOR WHICH SUCH PARTY HAS A RIGHT TO RECOVER FROM SUCH OTHER PARTY. 
 Section 13.14 Severability. In the event of a direct conflict between the provisions of this Agreement and any
mandatory provision of the Act or Laws, the applicable provision of the Act or other Laws, as the case may be, shall control. If any provision of this Agreement, or the application thereof to any Person or circumstance, is held invalid or
unenforceable to any extent, the remainder of this Agreement and the application of that provision to other Persons or circumstances shall not be affected thereby and that provision shall be enforced to the greatest extent permitted by the Act or
other Laws, as the case may be. 
 Section 13.15 Member Trademarks. Neither the Company nor any
Member (nor its Affiliates) shall be permitted to use any trademark owned by any other Member or its Affiliates, without the express written consent of such Member or its Affiliate or as otherwise required by Law. 
 Section 13.16 Integrated Transaction. Each Member has entered into this Agreement in consideration of (a) the
covenants and conditions set forth herein, the receipt and sufficiency of which are hereby acknowledged, and (b) the execution, delivery, and performance by the other Member, or an Affiliate thereof, as the case may be, of such other
Member’s (or its Affiliate’s) respective O&R Agreement, the Guaranties and the other contracts and agreements among the parties contemplated therein and/or executed pursuant thereto (collectively, the “Other Transaction
Documents”). The parties agree that neither Member would have entered into this Agreement without the Other Transaction Documents; the consideration for entering into this Agreement forms part of the consideration for entering into the
Other Transaction Documents; and in the event of the bankruptcy of either Member, this Agreement and the Other Transaction Documents must be rejected or assumed together. 
 Section 13.17 Bankruptcy Stay Waiver. Each Member agrees that in the event it should become a debtor in a bankruptcy proceeding, it expressly waives the provisions of Section 362
of the Bankruptcy Code as the same pertains to this Agreement. The automatic stay shall not apply to any rights or remedies asserted by the other Member in connection with this Agreement. 
 Section 13.18 Exercise of Certain Rights. No Member may maintain any action for partition of the property of the
Company. No Member may maintain any action for dissolution and liquidation of the Company unless such Member has first offered (which offer must expressly reference this Section 13.18) to sell its Membership Interest (free and clear of
all liens and encumbrances) to the other Member for an amount of cash equal to the Fair Market Value of the selling Member’s Membership Interest, determined by multiplying such selling Member’s Membership Interest by the Fair Market Value
of the Company, as a whole, without regard to any discounts or premiums related to minority interest, controlling interest, liquidity or related matters. If the Members do not agree on the Fair Market Value thereof, such value shall be determined in
accordance with the procedures set forth in Section 3.13. If the non-selling Member does not exercise the option to purchase such Membership Interest within 60 days after the Fair Market Value is determined, then the selling Member shall
have the right for a period of 30 days after such 60 day period to initiate an action for such dissolution and liquidation pursuant to section

18-802 of the Act or any similar applicable statutory or common law dissolution right. If no Member has brought such action for dissolution within such 30 day period, then any Member may maintain
an action for dissolution and liquidation only after again following the procedures set forth in this Section 13.18. Upon the institution of, and during the pendency of, any such dissolution proceeding, the Members agree to use
commercially reasonable efforts to employ procedures and experts to ensure that such dissolution process will result in the Company and/or its assets being disposed of at Fair Market Value; provided that such cooperative efforts shall not
constitute a waiver or limitation of any such Member’s right to contest such dissolution. Such procedures shall include soliciting likely potential purchasers, establishing a data room and other information sharing procedures and, if
appropriate, engaging an investment banker, consultant or other expert to facilitate and enhance the marketing efforts. The terms and conditions of this Section 13.18 are intended to preserve any right to dissolution created by statute
or common law (such as by section 18-802 of the Act), but do not create any contractual right to dissolution. 
 Section
13.19 Checks, Notes and Contracts. Checks and other orders for the payment of money shall be signed by such Person or Persons as the Managing Member shall from time to time determine. Contracts and other instruments or
documents may be signed in the name of the Company by any Person or Persons as the Managing Member shall from time to time determine authorized to sign such contract, instrument or document by the Company, and such authority may be general or
confined to specific instances. Checks and other orders for the payment of money made payable to the Company may be endorsed for deposit to the credit of the Company, with a depositary authorized by resolution of the Company, by any officer of the
Managing Member or such other Persons as the Managing Member may from time to time determine.

 SCHEDULE 6.12 
 MONTHLY G&A SERVICES FEE 
 The Managing Member
shall be entitled to charge the Company a monthly fee, the amount of which shall be determined by the Board by Unanimous Consent, as payment and reimbursement for costs associated with the Managing Member’s office rent and utilities,
communications expenses, data processing, general accounting services, general legal services (excluding costs of outside counsel and third party costs for defending and settling claims or litigation), administrative, materials and supplies costs,
and other similar items of business (the “G&A Services”) incurred in connection with its responsibilities as managing member of the Company. The costs of the G&A Services will be covered by this fixed fee rather than
reimbursed under Section 6.12 of the Agreement to which this Schedule 6.12 is attached. The monthly fee under this Schedule 6.12 shall be adjusted annually on February 4th (the “Adjustment
Date”) to an amount determined by multiplying the monthly reimbursement in effect for the immediately preceding calendar year by a fraction, the numerator of which shall be the implicit price deflator, seasonally adjusted, for the gross
domestic product as computed and most recently published by the U.S. Department of Commerce (“GDP”) for the year preceding the Adjustment Date, and the denominator of which shall be 100. If such price deflator is no longer
published, the Members shall agree upon a similar suitable index for adjustment of the monthly reimbursement hereunder. In addition to the foregoing adjustment, the Managing Member shall have the right to request adjustments to such fee on an annual
basis in connection with the Budget process to reflect any additional costs of fulfilling the Managing Member’s duties.
