16

17

(iii) disclosures to (A) a bona fide potential direct or indirect purchaser of such Member’s Units, (B) any financing source or potential financing source to a Member or the Affiliates of such Member, or (C) any advisors, consultants, accountants, attorneys, financing sources or potential financing sources, or other representatives of any bona-fide potential direct or indirect purchaser of such Member’s Units or any representatives of the foregoing, in each case, if such potential purchaser, financing source or potential financing source, or representative is subject to a confidentiality agreement with the Company obligating the potential purchaser, financing source, potential financing source, or representative to keep such Confidential Information confidential on terms no less favorable in any material respect to the Company than this Section 3.07; provided that no Class B Member (including holders of direct or indirect interests in a Class B Member) shall make any disclosure of any contract that is material to the Company or any of its Subsidiaries to such potential purchaser (or its financing sources or potential financing sources), except to the extent permitted by Law and such contract;

(iv) disclosures required with respect to a Member or an Affiliate of a Member, pursuant to (A) the Securities Act and the rules and regulations promulgated thereunder, (B) the Exchange Act and the rules and regulations promulgated thereunder, (C) any state securities Laws, (D) the rules and regulations of any National Securities Exchange on which such Member’s or its Affiliates’ Equity Securities are listed or admitted to trading, or (E) a routine audit, examination or investigation by a Governmental Authority or self-regulatory organization;

(A) provide the Company with prompt written notice (email being sufficient) of such requirements so that the Company may seek, at its sole cost and expense, a protective order or other appropriate remedy or waive compliance with the terms of this Section 3.07(b)(v);

(B) consult with the Company on the advisability of taking steps to resist or narrow such disclosure; and

(C) cooperate with the Company in any attempt the Company may make, at its sole cost and expense, to obtain a protective order or other appropriate remedy or assurance that confidential treatment will be afforded the Confidential Information; and in the event such protective order or other remedy is not obtained, or the Company waives compliance with the

18

provisions hereof, such Member agrees (I) to furnish only that portion of the Confidential Information that, on the advice of such Member’s internal or external legal counsel, such Member is legally required to disclose, and (II) to exercise commercially reasonable efforts to obtain assurance that confidential treatment will be accorded such Confidential Information; and

(vi) disclosures of Confidential Information to a Member’s accountants or attorneys to the extent reasonably necessary in connection with the preparation and filing of such Member’s tax returns.

(c) Notwithstanding anything to the contrary in this Section 3.07 (including Section 3.07(b)), no Class B Member (including a holder of direct or indirect interests in a Class B Member) shall make any disclosure of Confidential Information to an Excluded Party without the prior written consent of the Managing Member.

(d) Promptly after a Member no longer holds any of its Units, such Person shall, at such Member’s sole discretion, either (x) destroy (and (upon written request of the Company) provide a written confirmation (email being sufficient) of destruction to the Company with respect to) or (y) return to the Company all Confidential Information in its possession. Notwithstanding the immediately preceding sentence, but subject to the other provisions of this Section 3.07, such Person may retain for a stated period, but not disclose to any other Person (except as required by Law), Confidential Information for the limited purposes of (i) preparing such Member’s tax returns and defending audits, investigations, and proceedings relating thereto or (ii) complying with applicable Law or bona fide internal document retention policies; provided that such Person must keep such retained Confidential Information confidential in accordance with this Section 3.07 for so long as such information is retained. The Members understand and agree that a former Member’s computer systems may automatically back up Confidential Information, and to the extent that such computer back-up procedures create copies of the Confidential Information, the former Member may retain such copies in its archival or back-up computer storage for the period it normally archives backed-up computer records; provided that such copies are kept confidential for so long as such information is retained. All Confidential Information retained pursuant to this Section 3.07 shall not be used by the former Member during such period of retention other than as permitted under this Section 3.07.

(e) The Members agree that no adequate remedy at law exists for a breach or threatened breach of any of the provisions of this Section 3.07, the continuation of which unremedied will cause the Company to suffer irreparable harm. Accordingly, the Members agree that, to the fullest extent permitted by Law, the Company shall be entitled, in addition to other remedies that may be available to it, to immediate injunctive relief from any breach of any of the provisions of this Section 3.07 without the posting of a bond and to specific performance of its rights hereunder, as well as to any other remedies available at law or in equity, pursuant to Section 10.03 and Section 10.04.

4.02 Authorization and Issuance of Units.

(a) Class A Units. As of the Effective Date, the Class A Units are held by such Members and in such amounts as set forth on Exhibit A.

(b) Class B Units. As of the Effective Date, the Class B Units are held by such Members and in such amounts as set forth on Exhibit A. Any Class B Units acquired by Vistra Member or any Affiliate of Vistra Member or any other Person who owns or whose Affiliate owns any Class A Units (other than Class B Units repurchased or redeemed by the Company in accordance with this Agreement and thereupon cancelled) shall automatically be converted into and become Class A Units.

(c) Additional Units. Subject to Section 4.08, Section 6.02(a) and Section 12.04, as applicable, additional Membership Interests (“New Units”) of any class or series may be created and issued to existing Members or to other Persons, and such other Persons may be admitted to the Company as New Members, on such terms and conditions as the Managing Member may determine at the time of admission; provided that, for the avoidance of doubt, any foreclosure under a Permitted Loan Financing on pledged Units shall be permitted hereunder and the Managing Member shall, subject to Section 7.01(b), take all actions reasonably required to facilitate the admission of such New Members hereunder. The terms of admission or issuance must specify the amount of the initial Capital Contribution made to the Company and may provide for the creation of different classes or groups of Members having different rights, powers, and duties. Any such admission is effective only after the New Member has executed and delivered to the Managing Member an instrument containing the notice address of the New Member, the New Member’s ratification of this Agreement and agreement to be bound by it, and its confirmation that the representations and warranties in Section 3.02 are true and correct with respect to it. Any Person receiving newly issued Units shall make a Capital Contribution to the Company at the time of such issuance in an amount determined by the Managing Member. The provisions of this Section 4.02 shall not be construed to replace the restrictions set forth in Section 7.01.

4.03 Capital Contributions. Each Person who is a Member as of the Effective Date (other than the Managing Member) has made, or is deemed to have made, its respective Capital Contributions as set forth in the books and records of the Company. Without prejudice to the other provisions of this Article 4, any Capital Contribution made shall be treated as property of the Company and not the contributing Member. The Company hereby acknowledges and accepts that any Capital Contribution made or deemed to be made prior to the date of this Agreement shall be treated as having been contributed in consideration for the issuance of Units (as reflected by the holdings of Units set out in Exhibit A).

20

4.04 Capital Calls; Optional Capital Contributions.

(a) The Managing Member may from time to time make one or more capital calls to all, but not fewer than all, of the Members by written notice to the Members (each such written request, a “Capital Call” and such notice, a “Capital Call Notice”), which Capital Call Notice shall contain the following information: (i) the purpose for which the requested Capital Contribution will be used, (ii) the total amount of Capital Contributions requested from all Members, (iii) the amount of Capital Contribution requested from the Member to whom the request is addressed, which shall equal an amount equal to the total amount of the Capital Call multiplied by such Member’s Percentage Interest as of the date of such Capital Call, and (iv) the date on which payments of the Capital Contributions are due (which date shall not be less than 30 calendar days following the date on which the Capital Call Notice is given or sooner if the Managing Member determines that such Capital Contributions are needed as promptly as practicable) and the method of payment, and, subject to Section 4.04(b), the Members will have the option (but not the obligation) to make such additional Capital Contributions (“Subsequent Capital Contributions”) to the Company in accordance with the terms specified in such Capital Call. Notwithstanding the foregoing, no Member shall be required to make any Subsequent Capital Contribution (other than such Member’s Capital Contributions as of the Effective Date) to the Company pursuant to this Agreement.

(b) With respect to any Capital Call, if any Member (the “Non-Contributing Member”) does not elect or otherwise fails to make all or any portion of its share of any Subsequent Capital Contribution on the date specified in the Capital Call Notice pursuant to such Capital Call, then (i) notwithstanding anything in this Agreement to the contrary, such Non-Contributing Member hereby consents to the dilution of its Percentage Interest as provided in Section 4.04(d) in respect of Capital Calls and corresponding dilution made on a bona fide Fair Market Value basis and (ii) the Managing Member shall within three (3) Business Days after such failure to fund such Subsequent Capital Contribution (such notice, a “Capital Contribution Shortfall Notice”) deliver a written notice to each Member that has made its Subsequent Capital Contribution on or prior to the date specified in the Capital Call Notice (each such Member, with respect to such Subsequent Capital Contribution, a “Contributing Member”), stating the aggregate amount of such Subsequent Capital Contributions not made by the Non-Contributing Member(s) (in the aggregate, a “Capital Contribution Shortfall Amount”). The Contributing Members shall have the option to make Subsequent Capital Contributions to the Company in accordance with the procedure set forth in Section 4.04(c) to fund the Capital Contribution Shortfall Amount.

(c) In the event of a Capital Contribution Shortfall Amount, each Contributing Member electing to fund such Capital Contribution Shortfall Amount shall deliver, not more than ten (10) days after its receipt of the Capital Contribution Shortfall Notice, a written notice to the Company and each other Member, indicating whether such Contributing Member intends to provide its share (on a pro rata basis among all such electing Contributing Members based on such Contributing Members’ relative Percentage Interests) of such Capital Contribution Shortfall Amount through Subsequent Capital Contributions. Notwithstanding the foregoing, but subject to Section 6.02, with the consent of the Managing Member, the Contributing Members may, in lieu of making a Subsequent Capital Contribution with respect to all or any portion of the applicable Capital Contribution Shortfall Amount, provide one or more Member loans to the Company on such reasonable terms as such Contributing Member and the Managing Member may agree at the time of such funding.

21

(d) To the extent a Member funds Subsequent Capital Contributions pursuant to this Section 4.04, the Units and Percentage Interests of the Members shall be adjusted as follows: each Member shall be issued an additional number of Units proportional to the amount of such Subsequent Capital Contribution made by such Member, thereby diluting the Percentage Interest of the Non-Contributing Members, such increase and dilution to be based on the Fair Market Value of the Company immediately prior to the time of such Subsequent Capital Contribution as determined by the Managing Member. All Units issued to a Class A Member in respect of a Subsequent Capital Contribution shall be Class A Units, and all Units issued to a Class B Member in respect of a Subsequent Capital Contribution shall be Class B Units. Upon any such adjustment, the Managing Member shall update Exhibit A appropriately.

4.05 No Other Capital Contribution or Loan Obligations. No Member shall be required or permitted to make any Capital Contributions or loans to the Company except pursuant to this Article 4, except as otherwise agreed by such Member and the Managing Member, subject to Section 6.02, as applicable.

4.06 No Return of Contributions. Except as expressly provided herein, a Member is not entitled to the return of any part of its Capital Contributions or to be paid interest in respect of 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 any Member’s Capital Contributions.

4.07 Unit Certificates. As of the Effective Date, the Units will not be represented by certificates. Upon the written request of any Member to the Managing Member, its Units shall be evidenced by a Unit Certificate issued to such Member. Any Unit Certificate shall state on its face (a) that the Units evidenced thereby are subject to the restrictions of transfer set forth in this Agreement, as applicable, and (b) that it is subject to the terms and conditions of this Agreement. Only the Managing Member may authorize the issuance of a Unit Certificate, and the Unit Certificate shall be executed on behalf of the Company by any Officer or other authorized person of the Company. Evidence of the issuance of each Unit Certificate shall be recorded in the books of the Company. Upon the issuance of any Unit Certificate to any Member, the Company shall cause the Units of all other Members to also be evidenced by Unit Certificates and thereafter all Units shall be required to be evidenced by a Unit Certificate unless and until such time that this Agreement is further amended to provide that Units are no longer required to be evidenced by Unit Certificates (at which time the Members must also revoke the provisions of Section 12.09(a) of this Agreement).

4.08 Preemptive Rights.

(a) If following the Effective Date and prior to an IPO, the Company shall propose to, or the Managing Member shall propose to cause the Company to, issue any New Units or other Equity Securities to any Person, in each case other than in a Permitted Issuance (collectively, “Additional Securities”), then each Eligible Member (the “Preemptive Members”) shall have the right to purchase (the “Preemptive Right”), on the same terms and at the same

22

purchase price set forth in the Preemptive Notice, up to that number of Additional Securities (the “Pro Rata Share”) equal to the product of (x) the quotient (expressed as a percentage) obtained by dividing the Percentage Interest of such Preemptive Member by the aggregate Percentage Interest of all Preemptive Members and (y) the number of such Additional Securities to be issued.

(b) In connection with any issuance of Additional Securities, the Company shall, by written notice (the “Preemptive Notice”), provide an offer to sell to each Preemptive Member that number of Additional Securities of any proposed issuance equal to its Pro Rata Share (subject to the Additional Purchase Right) as calculated in accordance with Section 4.08(a), which Preemptive Notice shall include (i) the applicable purchase price per Additional Security, (ii) the aggregate amount of Additional Securities offered, (iii) the number of Additional Securities offered to such Preemptive Member as its Pro Rata Share in accordance with Section 4.08(a), (iv) the proposed closing date (which shall be no less than fifteen (15) Business Days from the date of such notice), (v) the place and time for the issuance thereof, and (vi) any other material terms and conditions of the offer. Within ten (10) Business Days after the date of receipt of the Preemptive Notice, any Preemptive Member wishing to exercise its Preemptive Right concerning such Additional Securities shall deliver notice to the Company setting forth the number of Additional Securities which such Preemptive Member irrevocably commits (unless such offering is terminated by the Company) to purchase (which may be for all or any portion of such Additional Securities offered to such Preemptive Member as its Pro Rata Share in the Preemptive Notice). Subject to the terms of Section 4.08(c), each Preemptive Member shall have the additional right (the “Additional Purchase Right”) to offer in its notice of exercise to purchase any or all of the Additional Securities not accepted for purchase by any other Preemptive Member, in which event such Additional Securities not accepted by any other Preemptive Member shall be deemed to have been offered to and accepted by the Preemptive Members exercising such Additional Purchase Right in proportion to their relative Percentage Interests on the same terms and at the same price per Additional Security as those specified in the Preemptive Notice, but in no event shall any Preemptive Member exercising its Additional Purchase Right be allocated a number of Additional Securities in excess of the maximum number such Preemptive Member has offered to purchase in its notice of exercise. Subject to the terms of Section 4.08(c), each Preemptive Member so exercising its right under this Section 4.08 shall be entitled and obligated to purchase that number of Additional Securities specified in such Preemptive Member’s notice on the terms and conditions set forth in the Preemptive Notice; provided that any such purchase shall occur simultaneously with the sale and purchase of all Additional Securities proposed to be sold in accordance with the Preemptive Notice.

(c) If the Preemptive Members fail to exercise the rights set forth in this Section 4.08 with respect to any portion of the Additional Securities, the Company shall have twelve (12) months from the date of the Preemptive Notice to sell such portion of the Additional Securities in respect of which such Preemptive Members’ rights were not exercised, at a price no less than the price set forth in the Preemptive Notice and on terms and conditions no less favorable in the aggregate to the Company than as stated in the Preemptive Notice. If the Company has not sold such Additional Securities within twelve (12) months of the date of the Preemptive Notice, then the Company shall not thereafter issue or sell any Additional Securities without first offering such Additional Securities to the Preemptive Members in accordance with this Section 4.08; provided, that, if the consummation of such sale is subject to the receipt of any Governmental Authorizations and such Governmental Authorizations have not been received by the end of such twelve (12) month period, such twelve (12) month period shall automatically be extended for an additional thirty (30) days following receipt of such Governmental Authorizations.

23

(d) Notwithstanding anything in this Section 4.08 to the contrary, the Company may at its option determine not to proceed with the offering contemplated by the Preemptive Notice, in which case (i) the Company shall provide written notice of such determination to the Preemptive Members, and (ii) any subsequent proposed issuance of Additional Securities shall once again be subject to the terms of this Section 4.08.

(e) Notwithstanding anything in this Agreement to the contrary, in lieu of offering Additional Securities to the Preemptive Members at the time such Additional Securities are offered to any other Person, the Company may comply with the provisions of this Section 4.08 by making an offer to sell (or cause to be sold) to the Preemptive Members all or any portion of their Pro Rata Share of such Additional Securities promptly after the sale to such other Person is consummated, in each case, taking into account the number of Additional Securities actually sold to such other Person; provided, that, such offer to the Preemptive Members shall be made promptly and in no event later than ten (10) Business Days following the consummation of the sale to such other Person.

DISTRIBUTIONS

5.01 Distributions of Available Cash. Subject to applicable Law (including Section 18-607 of the Act) and to any restrictions, conditions or other terms set forth in this Agreement, the Managing Member shall seek to distribute Available Cash (determined as of the end of each Quarter) to each Member on a pro rata basis in accordance with such Member’s respective Percentage Interest promptly following the end of such Quarter; provided, that notwithstanding the foregoing such distributions of Available Cash shall be made at such time and in such aggregate amounts as determined by the Managing Member.

5.02 Distributions on Dissolution and Winding-Up. Upon a Dissolution Event, all available proceeds distributable to the Members as determined under Section 11.02 shall be distributed to each Member on a pro rata basis based upon its respective Percentage Interest. If a distribution under Section 11.02 is in property other than cash, the value of such distribution shall be deemed to be the Fair Market Value of such property. A distribution in kind of an asset to a Member shall be deemed, for the purposes of Article 11, a distribution in an amount equal to the Fair Market Value of the assets so distributed.

5.03 Amounts Withheld. If the Company is required by Law to make any payment to any Governmental Authority that is specifically attributable to, or on behalf of, a Member (or former Member) in its capacity as such (including federal, state, local or non-U.S. withholding taxes), the Company is authorized to withhold from payments and distributions to the Members and to pay over to any federal, state, or local Governmental Authority any such amounts. All amounts withheld or paid over pursuant to the Code or any provisions of any other applicable Law with respect to any payment or distribution to a Member shall, to the extent properly remitted to the appropriate Governmental Authority, be treated for all purposes under this Agreement as amounts paid or distributed pursuant to this Article 5 to such Member with respect to which such amount was withheld. To the extent that any required withholding with respect to a Member is not satisfied by reducing from any concurrent cash distributions, such withholding may be satisfied from the next distributions made to such Member or, at the option of the Managing Member, such Member shall indemnify the Company for such withholding. Each Member will furnish the Managing Member and the Company with such information as may reasonably be requested by the Managing Member from time to time to determine whether withholding is required, and each Member will promptly notify the Managing Member and the Company if such Member determines at any time that it is subject to withholding. A Member’s obligation to indemnify and make payments to the Company under this Section 5.03 will survive the Transfer or termination of such Member’s interest in the Company, the termination of this Agreement and the termination, dissolution, liquidation and winding up of the Company, and for purposes of this Section 5.03, the Company will be treated as continuing in existence.

Notwithstanding the foregoing, nothing herein shall eliminate or limit (i) the express contractual provisions set forth herein or (ii) the implied contractual covenant of good faith and fair dealing.

28

(b) Each Member acknowledges its express intent, and agrees with each other Member for the mutual benefit of all the Members, that, except as expressly set forth in this Agreement:

Notwithstanding the foregoing, nothing in this Section 6.07 shall be deemed to impose fiduciary duties on any Member or otherwise modify or limit the standard of care set forth in Section 6.04.

(b) To the fullest extent permitted by Law, the Company shall indemnify and hold harmless each Covered Person from and against any and all Claims in which such Covered Person may be involved, or threatened to be involved, as a party or otherwise, arising out of or relating to the Company, its Subsidiaries or its or their respective business, assets, properties, or liabilities or any act or omission performed or omitted by such Covered Person in relation thereto; provided, however, that no Covered Person shall be entitled to indemnification under this

31

Section 6.07(b) with respect to any Claim to the extent (i) there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of such act or omission, and taking into account the acknowledgements and agreements set forth in this Agreement, such Covered Person has breached the express provisions of this Agreement or the implied contractual covenant of good faith and fair dealing, engaged in bad faith, fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that such Covered Person’s conduct was criminal or (ii) initiated by such Covered Person unless such Claim (or part thereof) (A) was brought to enforce such Person’s rights to indemnification hereunder or (B) was authorized or consented to by the Managing Member in connection with Claims brought against such Covered Person by Persons that are not the Company (or any of its Subsidiaries). Expenses incurred by a Covered Person in defending any Claim shall be paid by or on behalf of the Company in advance of the final disposition of such Claim upon receipt by the Company of an undertaking by or on behalf of such Covered Person to repay such amount if it shall be ultimately determined that such Covered Person is not entitled to be indemnified by the Company as authorized by this Section 6.07(b).

(c) The Company acknowledges and agrees that the obligation of the Company under this Agreement to indemnify or advance expenses to any Covered Person for the matters covered hereby shall be the primary source of indemnification and advancement for such Covered Person in connection therewith, and any obligation on the part of any other indemnitor under any other agreement to indemnify or advance expenses to such Covered Person shall be secondary to the Company’s obligation and shall be reduced by any amount that such Covered Person may collect as indemnification or advancement from the Company. Subject to the foregoing, the Company shall be subrogated to the rights of such Covered Person against, and shall be entitled to seek contribution from, any third party, including any insurance company, that is not an Affiliate of any Member (or any insurance policy covering such Member or its Affiliates) to recover the amount of such indemnification (or such portion thereof as to which the Company shall be entitled to contribution) after the Covered Person shall have been fully and completely indemnified (whether pursuant to this Agreement or otherwise) in respect of the Claim which gave rise to such indemnification. Any such Covered Person shall fully cooperate with the Company, at the Company’s expense, in its efforts to enforce against any such third party the rights to which it is so subrogated.

(d) The Company, as an indemnifying party from time to time, agrees that, to the fullest extent permitted by applicable Law, its obligation to indemnify Covered Persons under this Agreement shall apply to any amounts expended by any other indemnitor under any other agreement in respect of indemnification or advancement of expenses to any Covered Person in connection with any Claims to the extent such amounts extended by such other indemnitor are on account of any unpaid indemnity amounts hereunder.

(e) The right of any Covered Person to the indemnification provided herein is cumulative of, and in addition to, any and all rights to which such Covered Person may otherwise be entitled by contract or as a matter of Law or equity, and shall extend to such Covered Person’s successors, assigns, and legal representatives. The right of any Covered Person to the indemnification provided herein shall remain in full force and effect and continue as to any Person who ceases to be a Covered Person with respect to any indemnifiable claim to the extent arising (i) during the period in which such Person was a Covered Person, or (ii) out of facts, circumstances, events, or actions which took place during the period in which such Person was a Covered Person.

32

(f) The satisfaction of any indemnification obligation pursuant to this Section 6.07 shall be from and limited to the Company assets (including insurance and any agreements pursuant to which the Company or its officers or employees are entitled to indemnification) and no Member, in such capacity, shall be subject to personal liability with respect to such obligations.

(g) If this Section 6.07 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction or properly constituted arbitration panel, then the Company shall nonetheless, to the fullest extent permitted by applicable Law, indemnify and hold harmless each Person entitled to be indemnified pursuant to this Section 6.07 as to liabilities to the full extent permitted by any applicable portion of this Section 6.07 that shall not have been invalidated.

No Disposition of a Class B Unit shall be permitted if such Disposition would impose material liability or material reporting obligations on the Company or any Member thereof in any jurisdiction, whether domestic or foreign, or result in the Company or any Member thereof becoming subject to the jurisdiction of any Governmental Authority anywhere, other than the Governmental Authorities in which the Company or such Member is then subject to such liability, reporting obligation or jurisdiction.

(viii) Excluded Party. Other than any Disposition pursuant to Section 7.03 or Section 7.04, no Disposition of a Class B Unit (including Dispositions to Affiliates of a Class B Member) shall be made to an Excluded Party.

(c) Notwithstanding anything in this Agreement to the contrary, other than Dispositions pursuant to and in accordance with Sections 7.03, 7.04 or 7.05, no Member may Dispose of all or any portion of its Units to the extent the transferee is a Person who is a Related Party and such Disposition would result in a recapture or a disallowance of a tax credit claimed with respect to the output of any Company asset.

(d) Except for Permitted Loan Financings, no Class B Member shall use its Units or allow its Units to be used as collateral for the issuance of any securities or otherwise.

7.02 Vistra Right of First Offer.

(a) If, at any time, any Class B Member(s) or any of its direct or indirect equityholders (such Class B Member(s) on behalf of itself or its direct or indirect equityholders, an “Offering Member”) desires to Dispose of all or any portion of the Class B Units held directly or indirectly by such Offering Member that such Offering Member is permitted to sell pursuant to Section 7.01 to any Person (other than a Permitted Class B Transferee) that is not an Excluded Party, then the Offering Member will first provide written notice to Vistra Member offering to sell such Class B Units to Vistra Member, which notice shall (i) include the number of Class B Units to be Disposed (including Class B Units held indirectly through interests in the Avenue Aggregator, the “ROFO Units” and each such notice, a “ROFO Notice”) and (ii) state the Offering Member’s bona fide intention to Dispose of the ROFO Units. Vistra Member (or any Affiliate thereof) shall have a period of thirty (30) days after receipt of the ROFO Notice (the “ROFO Offering Period”) to propose a cash purchase price for all (but not less than all) of the ROFO Units, along with any other material terms and conditions applicable to the Disposition (an “Offer Notice”). The delivery of an Offer Notice shall constitute an irrevocable commitment for a period of ninety (90) days following delivery of such Offer Notice to purchase all of the ROFO Units specified in the Offer Notice at the cash price and on the terms set forth in the Offer Notice. The Offering Member may, in its sole discretion, accept or reject the offer in such Offer Notice by delivery of written notice to such effect (an “Acceptance Notice” or a “Rejection Notice”, as the case may be) to Vistra Member (or the applicable Affiliate thereof), within ten (10) Business Days after receipt of the Offer Notice (“ROFO Reply Period”). If the Offering Member does not timely deliver an Acceptance Notice or a Rejection Notice in response to an Offer Notice, then the

35

Offering Member will be deemed to have delivered an Acceptance Notice as of the end of the ROFO Reply Period. By delivering the ROFO Notice, subject to receipt and acceptance of an Offer Notice, the Offering Member shall be deemed to be representing and warranting to the Company and Vistra Member that the Offering Member has all of the necessary power and authority to sell such ROFO Units and that the ROFO Units are free and clear of any and all Encumbrances other than those arising under this Agreement. With respect to any proposed Disposition of Class B Units pursuant to this Section 7.02 that is not proposed to be a Disposition of Units directly by the applicable Class B Members, the applicable Offering Member and the applicable Class B Member shall cause the provisions of this Section 7.02 to apply in such manner so that Vistra Member has the right to acquire such Class B Units directly from the applicable Class B Member subject to and in accordance with this Section 7.02 as if such proposed indirect Disposition of ROFO Units were a proposed direct Disposition of such ROFO Units. For the avoidance of doubt, Vistra Member shall not, and shall have no right to, acquire any Equity Securities in any Class B Member (and instead shall have the right to acquire Class B Units as provided herein) in connection with the right of first offer set forth in this Section 7.02.

(b) If Vistra Member (or any Affiliate thereof) delivers an Offer Notice and the Offering Member delivers (or is deemed to have delivered) an Acceptance Notice, in each case within the time period provided for in Section 7.02(a), then Vistra Member (or the applicable Affiliate thereof) shall be obligated to purchase, and the Offering Member shall be obligated to sell to Vistra Member (or such Affiliate), such ROFO Units at such price and upon such terms and conditions as specified in the Offer Notice. The consummation of such purchase and sale shall occur on a date reasonably selected by Vistra Member that is within one hundred eighty (180) days after the delivery of such Acceptance Notice, unless a longer period is needed to obtain any Governmental Authorizations reasonably necessary to consummate the ROFO Unit purchase and sale in accordance with Section 7.02(c). Unless otherwise mutually agreed, the closing of such purchase and sale shall be consummated by exchange of electronic documents and signatures.

(c) The Company, Vistra Member and the Offering Member will cooperate in the obtaining of all Governmental Authorizations and third-party approvals and consents (including clearances and expirations of waiting periods) reasonably necessary to consummate, and will use their respective commercially reasonable efforts to satisfy any conditions to the consummation of, a ROFO Unit purchase and sale under this Section 7.02; provided that in no circumstance shall anything contained in this Agreement be deemed to require Vistra Member or the Offering Member to (i) pay any money to any Governmental Authority or other Person with respect to obtaining such Governmental Authorizations or third party approvals or consents (other than de minimis filing fees or similar costs) or (ii) agree to undertake any action or to provide any efforts with respect to obtaining any Governmental Authorization or other third-party approvals, consents or clearances that includes an obligation to litigate with any Governmental Authority or other body or to divest or hold separate any assets or investments of such Member or its Affiliates or the Company or its Subsidiaries or to take any other mitigating action that could negatively affect the reputation or other assets or investments of such Member or its Affiliates or the Company or its Subsidiaries.

36

(d) If Vistra Member (or any Affiliate thereof) delivers an Offer Notice and the Offering Member delivers a Rejection Notice, in each case within the time periods provided for in Section 7.02(a), then neither Vistra Member nor any Affiliate thereof shall be obligated to purchase, and the Offering Member shall not be obligated to sell to any such Person, the ROFO Units, and the Offering Member may sell (subject to compliance with Section 7.01), the ROFO Units to any Person that is not an Affiliate of the Offering Member (or a Permitted Class B Transferee of the Class B Member whose Units are the subject of the proposed Disposition) or an Excluded Party (i) at an aggregate price per Unit (as reasonably allocated by the Offering Member in good faith to the ROFO Units in connection with any indirect Disposition of ROFO Units that is permitted to be made pursuant to this Section 7.02) that is not less than one hundred and three percent (103%) of the aggregate price per Unit set forth in the Offer Notice and (ii) otherwise on terms as or more favorable to such Person than set forth in the Offer Notice, taken as a whole. If such sale is not consummated within twelve (12) months after the expiry of the ROFO Offering Period, then the Offering Member may not effect a Disposition of all or any portion of the ROFO Units without again delivering a ROFO Notice to Vistra Member in accordance with the terms hereof and otherwise complying with this Section 7.02, except as otherwise expressly permitted pursuant to Article 7; provided, that, if the consummation of such sale is subject to the receipt of any Governmental Authorizations and such Governmental Authorizations have not been received by the end of such twelve (12) month period, such twelve (12) month period shall automatically be extended for an additional thirty (30) days following receipt of such Governmental Authorizations.

(e) If neither Vistra Member nor any Affiliate thereof delivers an Offer Notice within the time periods provided for in Section 7.02(a), then neither Vistra Member nor any Affiliate thereof shall be obligated to purchase, and the Offering Member shall not be obligated to sell to any such Person, the ROFO Units, and the Offering Member may sell (subject to compliance with Section 7.01) the ROFO Units to any Person that is not an Affiliate of the Offering Member (or a Permitted Class B Transferee of the Class B Member whose Units are the subject of the proposed Disposition) or an Excluded Party (i) at any price and (ii) on any terms it may, in its sole discretion, find agreeable. If such sale is not consummated within twelve (12) months after the expiry of the ROFO Offering Period, then the Offering Member may not effect such a Disposition of all or any portion of the ROFO Units without again delivering a ROFO Notice to Vistra Member in accordance with the terms hereof and otherwise complying with this Section 7.02, except as otherwise expressly permitted pursuant to Article 7; provided, that, if the consummation of such sale is subject to the receipt of any Governmental Authorizations and such Governmental Authorizations have not been received by the end of such twelve (12) month period, such twelve (12) month period shall automatically be extended for an additional thirty (30) days following receipt of such Governmental Authorizations. For the avoidance of doubt, any sale of ROFO Units to a third party pursuant to and in compliance with Section 7.02(d) or this Section 7.02(e) shall not require the prior written consent of the Managing Member pursuant to Section 7.01(a)(i).

(f) In connection with the proposed Disposition of ROFO Units that represent a Percentage Interest equal to at least ten percent (10%) to any Person other than Vistra Member pursuant to this Section 7.02, the Managing Member agrees to use commercially reasonable efforts, at the expense of the Offering Member, to cooperate in the marketing and Disposition of such ROFO Units to bona fide potential purchasers of such ROFO Units if such potential purchaser is subject to a customary confidentiality agreement with the Company with respect to the use and disclosure of any Confidential Information, including by (i) providing such financial and operational information with respect to the Company and its Subsidiaries as the Class B Member Representative may reasonably request (so long as such information is reasonably available), and

37

(ii) otherwise causing representatives of the Company and its Subsidiaries to cooperate (including by participating at reasonable times and in a reasonable number of management presentations, preparing marketing materials, and making reasonable diligence materials available in an electronic data room) with the Class B Member Representative, as reasonably requested by the Class B Member Representative, in connection with the marketing and Disposition of such ROFO Units. Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries shall be required to afford access or furnish information pursuant to this Section 7.02(f) to the extent (x) such information is subject to the terms of a confidentiality obligation with a third party or (y) the Company reasonably determines in good faith that affording such access or furnishing such information would (A) result in the disclosure of trade secrets of third parties, (B) cause competitive harm to the Company or its Subsidiaries, (C) expose the Company to risk of liability under data protection Laws for disclosure of personal information, (D) jeopardize the attorney-client or other privilege of the Company or any of its Subsidiaries or (E) violate applicable Law. Nothing in this Section 7.02(f) will be construed to require the Company or its Subsidiaries or any of their respective representatives to prepare any reports, analyses, appraisals, opinions or other information.

(g) For the avoidance of doubt, this Section 7.02 will not apply with respect to any Disposition made pursuant to and in accordance with Sections 7.01(a)(i) or (ii), 7.03, 7.04, or 7.05, and any proposed Disposition of Units that includes the ROFO Units initiated pursuant to Section 7.03 following the delivery of a ROFO Notice with respect to such ROFO Units shall instead be subject to the terms and conditions of Section 7.03 and the Offering Members shall have no further rights to Dispose of such ROFO Units under this Section 7.02 with respect to such originally initiated Disposition of such ROFO Units without again delivering a ROFO Notice to Vistra Member in accordance with the terms hereof and otherwise complying with this Section 7.02.

(h) Notwithstanding anything to the contrary in this Agreement, without the prior written consent of the Managing Member, Dispositions of Class B Units held by a Class B Member pursuant to this Section 7.02 (i) shall not be made more than one time per quarter of a Fiscal Year, (ii) shall not be made for a Percentage Interest of less than one percent (1%) in any Disposition unless such Disposition is made prior to the first anniversary of the Effective Date, and (iii) subject to the foregoing clauses (i) and (ii), may be made by any Class B Member and each beneficial holder in the Avenue Aggregator whether it holds Class B Units directly or indirectly through such Class B Member.

(i) Vistra Member will have the right to assign to the Company all or any portion of its rights under this Section 7.02.

(j) The provisions of this Section 7.02 will terminate immediately prior to the effectiveness of the registration statement in connection with a Qualified IPO.

7.03 Drag-Along Right.

(a) Notwithstanding anything to the contrary contained in this Agreement, so long as Vistra Member together with its Affiliates holds a Percentage Interest of at least fifty percent (50%), if Vistra Member and its Affiliates (the “Dragging Member”) propose to Dispose of greater than 50% of the Units then owned by Vistra Member and its Affiliates to a Person (other than an Affiliate of Vistra Member) (whether such Disposition is by way of purchase, exchange, merger, other form of transaction or a Sale of the Company, a “Drag-Along Transaction”), then, upon request of the Dragging Member, the Managing Member (the “Drag-Along Notifying Party”) shall notify each other Member (each, a “Drag-Along Member”) in writing at least ten (10) days prior to the consummation of the Drag-Along Transaction. Such notice shall identify the proposed purchaser, the number and type of Units to be sold (if applicable), the consideration offered and any other material terms and conditions of the Drag-Along Transaction, in each case, to the extent then-known. If the Drag-Along Notifying Party delivers such notice: (i) each Drag-Along Member shall sell the Applicable Drag Percentage of the Units held by such Drag-Along Member (provided, that, if the Drag-Along Transaction constitutes a Sale of the Company, then each Class B Member shall sell all of its Class B Units), (ii) each Drag-Along Member shall be deemed to approve the proposed Drag-Along Transaction, (iii) to the extent any vote or consent to such Drag-Along Transaction is required, each Drag-Along Member shall vote for and consent to such Drag-Along Transaction (including on behalf of all of its Units and on behalf of all Units with respect to which such Drag-Along Member has the power to direct the voting) and shall waive any dissenters’ rights, appraisal rights or similar rights which such Drag-Along Member may have in connection therewith, (iv) no Drag-Along Member shall raise any objections to the proposed Drag-Along Transaction, (v) subject to clause (vi) below, each Drag-Along Member shall execute all documents reasonably required to effectuate such Drag-Along Transaction, as determined by the Drag-Along Notifying Party, and (vi) each Drag-Along Member shall be obligated to provide (A) representations and warranties as are customary for transactions of the type, provided that no Drag-Along Member shall be required to make representations and warranties in connection with such Drag-Along Transaction other than customary representations and warranties with respect to (I) such Drag-Along Member’s due organization, power and authority, (II) such Drag-Along Member’s ownership of its Units and ability to freely Dispose such Units without Encumbrances (other than by reason of this Agreement), (III) non-contravention of such Drag-Along Member’s charter, bylaws or other organizational documents and non-contravention of Laws or judgments and (IV) the enforceable nature of such Drag-Along Member’s obligations under the documents for such sale to which it is a party, subject to customary exceptions (collectively, the “Member Representations”), to the extent such Member Representations shall also be made by other Drag-Along Members and the Dragging Member, and (B) covenants as are customary for transactions of the type (but not any non-competition, non-solicitation, or similar restrictive covenants other than customary confidentiality covenants). To the extent indemnification is required of the Drag-Along Members in connection with a Drag-Along Transaction, no Drag-Along Member will be required to be liable in respect of any indemnification provided in connection with such Drag-Along Transaction (w) for any amount in excess of (I) such Drag-Along Member’s pro rata share (based upon the relative aggregate amounts of consideration received by such Drag-Along Member as compared to the aggregate amounts received by all Members participating in such Drag-Along Transaction) of such indemnified amount, or (II) the consideration received by such Drag-Along Member in such Drag-Along Transaction, (x) for the breach of any other Drag-Along Member’s Member Representations, (y) for the breach of the Dragging Member’s Member Representations (or pursuant to an escrow for representations and warranties of the Company), or (z) other than on a several (and not a joint and several) basis with other Drag-Along Members and Vistra Member. Subject to the foregoing, each Drag-Along Member shall take all other actions reasonably necessary or desirable, as determined by the Drag-Along Notifying Party, to cause the consummation of the Drag-Along Transaction on the terms proposed by the Drag-Along Notifying Party.

39

(b) Upon the consummation of the Drag-Along Transaction, each Drag-Along Member shall receive, with respect to each Unit Disposed of by it in such Drag-Along Transaction, the same form (or the same choice of form) and amount of per Unit consideration as each other Member participating in such Drag-Along Transaction (less any applicable taxes or withholding obligations). The total consideration payable to the Members in connection with a Drag-Along Transaction shall be allocated among the Members in accordance with Section 5.01 and, for this purpose, such total consideration will be computed based upon the sum of (i) the cash included in such consideration, plus (ii) the Fair Market Value of any non-cash property included in such consideration; provided that, notwithstanding anything to the contrary herein, the Managing Member, at the direction of the Drag-Along Notifying Party, may elect to make any such distribution of non-cash property subject to restrictions (including the use of escrow accounts, lock-ups, or other contractual restrictions on the beneficial rights in respect of such shares or other equity interests) so long as such restrictions do not adversely affect the intended economic rights, preferences, privileges, or powers of the Members in respect of their Units.

(c) If a Drag-Along Transaction is consummated, then each Drag-Along Member shall bear a pro rata share (based upon the relative aggregate amounts of consideration received by such Drag-Along Member as compared to the aggregate amounts received by all Members participating in such Drag-Along Transaction) of all costs of the Drag-Along Transaction to the extent such costs are not otherwise paid by the Company or the acquiring party. The fees, costs, and expenses (including legal and expert fees and expenses) incurred by the Drag-Along Notifying Party and its Affiliates in connection with the consummation of a Drag-Along Transaction shall be deemed to be for the benefit of all Members for purposes of this Section 7.03(c), whether or not the Drag-Along Transaction is consummated; provided, that, if the Drag-Along Transaction is consummated, in no event shall any such Drag-Along Member’s pro rata share of the costs of the Drag-Along Transaction exceed the proceeds actually received by such Drag-Along Member in the Drag-Along Transaction. Costs incurred by any Drag-Along Member in connection with a Drag-Along Transaction shall not be considered costs of the Drag-Along Transaction hereunder and shall be the sole responsibility of such Drag-Along Member.

(d) In connection with a Drag-Along Transaction pursuant to this Section 7.03:

(i) if requested by the Drag-Along Notifying Party, the Company will promptly engage, on customary terms (including customary indemnification from the Company), a nationally recognized investment banking firm selected by the Managing Member to provide financial advisory services to the Company, and the Company shall pay the fees and expenses of such investment banking firm; and

(ii) the Company and the Members will cooperate in the obtaining of all Governmental Authorizations and third-party approvals and consents (including clearances and expirations of waiting periods) reasonably necessary to consummate, and will use their respective commercially reasonable efforts to satisfy any conditions to the consummation of, a Drag-Along Transaction under this Section 7.03; provided, that in no circumstance shall anything contained in this Agreement be deemed to require any Member to (i) pay

40

any money to any Governmental Authority or other Person with respect to obtaining such Governmental Authorizations or third party approvals or consents (other than de minimis filing fees or similar costs) or (ii) agree to undertake any action or to provide any efforts with respect to obtaining any Governmental Authorization or other third-party approvals, consents or clearances that includes an obligation to litigate with any Governmental Authority or other body or to divest or hold separate any assets or investments of such Member or its Affiliates or the Company or its Subsidiaries or to take any other mitigating action that could negatively affect the reputation or other assets or investments of such Member or its Affiliates or the Company or its Subsidiaries.

(e) If the Drag-Along Transaction is not consummated within twelve (12) months from the delivery of the notice of Drag-Along Transaction pursuant to Section 7.03(a), then the Drag-Along Notifying Party must again comply with the notice and other requirements of this Section 7.03 in connection with any proposed Drag-Along Transaction; provided, that, if the consummation of such sale is subject to the receipt of any Governmental Authorizations and such Governmental Authorizations have not been received by the end of such twelve (12) month period, such twelve (12) month period shall automatically be extended for an additional thirty (30) days following receipt of such Governmental Authorizations.

(f) Notwithstanding anything contained in this Section 7.03, there shall be no liability on the part of the Drag-Along Notifying Party to the other Members (other than the obligation to return the limited power of attorney and the certificates, if any, and other applicable instruments representing Units received by the Drag-Along Notifying Party) or any other Person if the Drag-Along Transaction pursuant to this Section 7.03 is not consummated for whatever reason, regardless of whether the Drag-Along Notifying Party has delivered a notice of a Drag-Along Transaction pursuant to Section 7.03(a). The decision regarding whether to effect a Drag-Along Transaction pursuant to this Section 7.03 by the Drag-Along Notifying Party shall be in the sole and absolute discretion of the Drag-Along Notifying Party.

(g) With respect to a Drag-Along Transaction, each Member irrevocably constitutes and appoints a designee of the Dragging Member, with full power of substitution and resubstitution, as its true and lawful attorney in fact and agent with full power and authority in its name, place and stead to execute, acknowledge, verify, deliver, swear to, file and record at the appropriate public offices such documents as the Dragging Member deems necessary to carry out (to the extent consistent with the terms hereof) the provisions of this Section 7.03, including all consents, agreements and other instruments necessary to reflect or give effect to the provisions of this Section 7.03. The appointment by all Members of a designee of the Dragging Member, as attorney-in-fact, in each case to the extent set forth in the foregoing sentences of this Section 7.03(g), shall be deemed to be a power coupled with an interest, in recognition of the fact that each of the Members under this Agreement will be relying upon the power of a designee of the Dragging Member, to act as contemplated by this Section 7.03 in any filing and other action by it on behalf of the Company, shall survive the incapacity of any Person hereby giving such power, and the Disposition of all or any portion of the Units of such Person in the Company, and shall not be affected by the subsequent incapacity of such Person; provided that in the event of the Disposition by a Member of all of its Units in the Company, the foregoing power of attorney of a Disposing Member shall survive such Disposition and shall apply with respect to such Assignee upon such Assignee being admitted as a New Member pursuant to this Agreement. This power of

41

attorney may be exercised by such attorney-in-fact for all Members (or any of them) by a single signature of a designee of the Dragging Member, acting as attorney-in-fact with or without listing all of the Members executing an instrument. Any Person dealing with the Company may conclusively presume and rely upon the fact that any instrument referred to above, executed by any holder of this power of attorney, is authorized, legal, valid and binding, without further inquiry. If required, each Member shall execute and deliver to a designee of the Dragging Member, within five (5) days after the receipt of a request therefor, such further designations, powers of attorney or other instruments as a designee of the Dragging Member, shall reasonably deem necessary for the purposes hereof. The Dragging Member shall keep the Class B Member Representative reasonably informed with respect to the status of all material matters handled by the Dragging Member under this Section 7.03(g) as reasonably requested by the Class B Member Representative.

(h) The Drag-Along Notifying Party shall not be entitled to consummate a Drag-Along Transaction pursuant to this Section 7.03 unless the gross consideration allocable to the Rollover Members in connection with such Drag-Along Transaction in respect of their Class B Units is equal to or exceeds the Fair Market Value of the Class B Units held by the Rollover Members.

(i) The provisions of this Section 7.03 shall terminate upon the earlier of (i) immediately prior to the effectiveness of the registration statement in connection with a Qualified IPO and (ii) a Class B Liquidity Event.

7.04 Tag-Along Rights.

(a) In the event Vistra Member and its Affiliates (in its capacity as such, a “Tag-Along Transferor”) proposes to Dispose of at least five percent (5%) of the then outstanding Class A Units to a Person (other than an Affiliate of Vistra Member), other than pursuant to Section 7.03 or Section 7.05, such Tag-Along Transferor shall deliver a written notice (the “Tag-Along Notice”) to the Class B Member Representative (on behalf of each Class B Member so long as the Class B Members collectively hold a Percentage Interest of at least five percent (5%)) (each such Class B Member, a “Tag-Along Offeree” ) at least twenty (20) days prior to consummating such Disposition (the “Tag-Along Transaction” ) specifying the identity of the prospective transferee(s) (to the extent then known), the number of the Tag-Along Transferor’s Units to be Disposed (the “Tag-Along Units”), the percentage of the Tag-Along Transferor’s aggregate Units to be Disposed (the “Tag-Along Percentage” ), and a summary of the material terms and conditions of the Disposition (if known). Each Tag-Along Offeree may elect to participate in the contemplated Disposition, at the same price per Unit and on the same terms and conditions applicable to the sale of the Class A Units by the Tag-Along Transferor in the Tag-Along Transaction as set forth in the Tag-Along Notice, by delivering written notice to the Tag-Along Transferor within fifteen (15) days after delivery of the Tag-Along Notice, which notice shall specify the number of Units that such Tag-Along Offeree desires to include in such proposed Disposition; provided that such number of Units shall not exceed the product of the Tag-Along Percentage and the total number of Units then held by such Tag-Along Offeree unless the consummation of such Disposition of Tag-Along Units by the Tag-Along Transferor would result in a Change of Control of the Company, in which case the Class B Member Representative may specify all or any portion of the Class B Units owned by each of the Tag-Along Offerees. If any Tag-Along Offeree does not give

42

such notice prior to the expiration of the fifteen (15) day period for giving such notice, then such Tag-Along Offerees will be deemed to have elected not to participate in the Tag-Along Transaction. If no Tag-Along Offeree elects to participate in the Tag-Along Transaction (or if no Tag-Along Offeree timely delivers notice of its desire to participate in the Tag-Along Transaction), then the Tag-Along Transferor may Dispose of the applicable Tag-Along Units to any Person on the terms set forth in the Tag-Along Notice without any further obligation to the Tag-Along Offerees under this Section 7.04. If the Tag-Along Transaction is not consummated within twelve (12) months of the date of the Tag-Along Notice, then the Tag-Along Transferor must again comply with the terms of this Section 7.04 before Disposing of the Tag-Along Units; provided, that, if the consummation of such sale is subject to the receipt of any Governmental Authorizations and such Governmental Authorizations have not been received by the end of such twelve (12) month period, such twelve (12) month period shall automatically be extended for an additional thirty (30) days following receipt of such Governmental Authorizations.

(b) If one or more Tag-Along Offerees exercise their right of participation pursuant to Section 7.04(a), then, at the Tag-Along Transferor’s option, (a) the number of Units that the Tag-Along Transferor and each other participating Tag-Along Offeree may sell in the Tag-Along Transaction shall be reduced on a pro rata basis (based on the relative number of Units that each such Person validly elects to sell in such Tag-Along Transaction) to a number equal to the overall number of Units to be sold to the prospective purchaser, (b) the aggregate number of Units to be sold in the Tag-Along Transaction shall be increased to accommodate the Units of those participating Tag-Along Offerees pursuant to this Section 7.04, or (c) the Tag-Along Transferor shall acquire from each such exercising Tag-Along Offeree the number of Units that such Tag-Along Offeree requested to Dispose of to such prospective purchaser on substantially the same price, terms and conditions as would be applicable in a direct sale of such Units to the prospective purchaser pursuant to Section 7.04(a).

(c) In connection with any Tag-Along Transaction pursuant to this Section 7.04: (i) each participating Tag-Along Offeree shall be deemed to approve the proposed Tag-Along Transaction, (ii) to the extent any vote or consent to such Tag-Along Transaction is required, each participating Tag-Along Offeree shall vote for and consent to such transaction (including on behalf of all of its Units and on behalf of all Units with respect to which such Tag-Along Offeree has the power to direct the voting) and shall waive any dissenters’ rights, appraisal rights or similar rights which such Tag-Along Offeree may have in connection therewith, (iii) no participating Tag-Along Offeree shall raise any objections to the proposed Tag-Along Transaction, (iv) subject to clause (v) below, each participating Tag-Along Offeree shall execute all documents reasonably required to effectuate such Tag-Along Transaction, as determined by the Tag-Along Transferor, and (v) each participating Tag-Along Offeree shall be obligated to provide (A) representations and warranties as are customary for transactions of the type, provided, that no such Tag-Along Offeree shall be required to make representations and warranties in connection with such sale other than Member Representations, to the extent such Member Representations shall also be made by other participating Tag-Along Offerees and the Tag-Along Transferor, and (B) covenants as are customary for transactions of the type (but not any non-competition, non-solicitation or similar restrictive covenants other than customary confidentiality covenants). To the extent indemnification is required of the participating Tag-Along Offerees in connection with a Tag-Along Transaction, no such Tag-Along Offeree will be required to be liable in respect of any indemnification provided in connection with such Tag-Along Transaction (x) for any amount

43

in excess of (I) such Tag-Along Offeree’s pro rata share (based upon the relative aggregate amounts of consideration received by such Tag-Along Offeree as compared to the aggregate amounts received by all Members participating in the Tag-Along Transaction) of such indemnified amount, or (II) the consideration received by such Tag-Along Offeree in such Tag-Along Transaction, (y) for the breach of any other participating Tag-Along Offeree’s Member Representations or the Tag-Along Transferor’s Member Representations and (z) other than on a several (and not a joint and several) basis with other participating Tag-Along Offerees and the Tag-Along Transferor. Each participating Tag-Along Offeree shall take all other actions reasonably necessary or desirable, as determined by the Tag-Along Transferor, to cause the consummation of such transaction on the terms proposed by the Tag-Along Transferor; provided, that, in no circumstance shall anything contained in this Agreement be deemed to require any Tag-Along Offeree to (i) pay any money to any Governmental Authority or other Person with respect to obtaining any Governmental Authorizations or third party approvals or consents (other than de minimis filing fees or similar costs) or (ii) agree to undertake any action or to provide any efforts with respect to obtaining any Governmental Authorization or other third-party approvals, consents or clearances that includes an obligation to litigate with any Governmental Authority or other body or to divest or hold separate any assets or investments of such Member or its Affiliates or the Company or its Subsidiaries or to take any other mitigating action that could negatively affect the reputation or other assets or investments of such Member or its Affiliates or the Company or its Subsidiaries.

(d) Upon the consummation of the Tag-Along Transaction, each participating Tag-Along Offeree shall receive, with respect to the Units disposed of by it in the Tag-Along Transaction, the same form (or the same option of form) and amount of per Unit consideration as each other Member participating in the Tag-Along Transaction, including the Tag-Along Transferor (less any applicable taxes or withholding obligations) and, for the avoidance of doubt, the same price per Unit as received by the Tag-Along Transferor for the Tag-Along Units; provided that, notwithstanding anything to the contrary herein, the Managing Member, at the direction of the Tag-Along Transferor, may elect to make any distribution of non-cash property received as part of the consideration for a Tag-Along Transaction subject to restrictions (including the use of escrow accounts, lock-ups, or other contractual restrictions on the beneficial rights in respect of such shares or other equity interests) so long as such restrictions do not adversely affect the intended economic rights, preferences, privileges, or powers of the Tag-Along Transferor and the Tag-Along Offerees in respect of their Units.

(e) If a proposed Tag-Along Transaction is consummated, each participating Tag-Along Offeree shall bear a pro rata share (based on the relative aggregate amounts of consideration received by such Tag-Along Offeree as compared to the aggregate amounts received by all Members participating in such Tag-Along Transaction) of all costs of sale of the Units pursuant to such Tag-Along Transaction to the extent such costs are not otherwise paid by the Company or the acquiring party. The fees, costs, and expenses (including legal and expert fees and expenses) incurred by the Tag-Along Transferor and its Affiliates in connection with the consummation of a Tag-Along Transaction shall be deemed to be for the benefit of the Tag-Along Transferor and all Tag-Along Offerees for purposes of this Section 7.04(e), whether or not the Tag-Along Transaction is consummated; provided, that, if the Tag-Along Transaction is consummated, in no event shall any such Tag-Along Offeree’s pro rata share of the costs of the Tag-Along Transaction exceed the proceeds actually received by such Tag-Along Offeree in the Tag-Along Transaction. Costs incurred by any participating Tag-Along Offeree in connection with a Tag-Along Transaction shall not be considered costs of the transaction hereunder and shall be the sole responsibility of such Tag-Along Offeree.

(f) The provisions of this Section 7.04 shall terminate upon the earlier of (i) immediately prior to the effectiveness of the registration statement in connection with a Qualified IPO and (ii) a Class B Liquidity Event.

7.05 Initial Public Offering.

(a) Notwithstanding anything to the contrary in this Agreement, in the event that the Managing Member determines to effect a Qualified IPO, the Members agree to cooperate to effect such reorganization or other transaction and enter into such other agreements that the Managing Member determines are necessary or appropriate to effect such Qualified IPO, including all actions that the Managing Member determines are necessary to (i) cause the conversion of all or any portion of the Company or any Subsidiary of the Company into a corporation, by (A) the direct or indirect transfer of all of the assets of the Company, subject to the Company’s liabilities, or of any portion of such assets and liabilities, to one or more corporations in exchange for shares of any such corporations, (B) the conversion of the Company or a Subsidiary of the Company into a corporation pursuant to Section 18-216 of the Act (or any successor section thereto) or (C) the transfer by each Member of Units held by such Member to one or more corporations in exchange for shares of any such corporation (including by merger of the Company into a corporation) or (ii) cause the Company to use any other structure or means by which to effect a Qualified IPO; provided, that, in each case the relative rights, preferences, privileges, and powers to which the Class B Members are entitled hereunder shall not be modified in a manner materially adverse to the holder thereof as compared to the rights, preferences, privileges, or powers to which such holder is entitled hereunder. In connection therewith, each Member agrees (if directed by the Managing Member) to exchange its Units for equity interests in a new holding company, or common shares of a corporation or other public vehicle (the entity used to effectuate a Qualified IPO, as designated by the Managing Member, the “IPO Entity”), which equity interests or shares shall have the relative rights, preferences, privileges, and powers to which such holder is entitled hereunder, and shall be issued to the Members in a manner which maintains the relative Percentage Interest of each such Member (such exchanged shares, “Conversion Shares”).

(b) Promptly following the determination of the number of Conversion Shares to be received in respect of each Unit under Section 7.05(a) (if any), each Member shall deliver to the Company the certificates, if any, representing the Units to be converted into Conversion Shares, duly endorsed or assigned in blank or to the Company (if required by it) and stating the name or names (with address) in which certificates or certificates for the Conversion Shares, if any, are to be issued.

(c) The Members shall, and hereby agree to take any and all actions deemed necessary or appropriate by the Managing Member in connection with the consummation of those actions contemplated by this Section 7.05 (subject to the terms and conditions hereof), including entering into agreements (i) providing for the exchange of Units as contemplated by Section 7.05(a) (and consents and waivers of claims in connection therewith), (ii) containing customary lock-up and resale restrictions and (iii) to vote all Conversion Shares held by them to

45

elect persons designated by the Managing Member as the directors of the IPO Entity. In connection with a Qualified IPO contemplated by this Section 7.05, the Company, the IPO Entity and the applicable Members shall enter into a customary registration rights agreement, which shall include customary piggyback registration rights; provided, however, that no such registration rights agreement shall be required to include demand registration rights for any holder of Class B Units or its Affiliates. The rights and restrictions set forth in Article 7 will expire immediately prior to the closing of such Qualified IPO, and the Conversion Shares issued to the Members shall be subject to (x) applicable restrictions under federal and state securities laws, and (y) any restrictions set forth in the agreements or other instruments relating to the Qualified IPO or any transfer, merger, consolidation or other restructuring or reorganization transaction entered into in anticipation or contemplation of such Qualified IPO. For the avoidance of doubt, no exchange or conversion of any Unit (or any portion thereof) contemplated by this Section 7.05 shall be deemed a “Disposition” for purposes of this Agreement.

(d) When determining what structure to implement for the Qualified IPO and what actions to be undertaken to facilitate the Qualified IPO, the Managing Member shall use commercially reasonable efforts to implement a structure that the Managing Member determines in good faith to be reasonably tax-efficient for the Members and their direct and indirect equityholders (taken as a whole); provided, that, for the avoidance of doubt, no Member shall be required to make any Capital Contribution or other investment in connection with any of the foregoing (other than to exchange its Units for Conversion Shares); provided, further, that, in connection with a Qualified IPO, (x) any amendment, modification or other changes to this Agreement or the Delaware Certificate and (y) any merger, recapitalization, share contributions or other restructurings or reorganizations shall all be contingent on the consummation of such Qualified IPO.

7.06 Determination of Fair Market Value.

(a) “Fair Market Value” means, with respect to any asset, security or interest, the fair market value of such asset, security or interest, as reasonably determined by the Managing Member, which determination shall be conclusive, final and binding for all purposes under this Agreement, except as otherwise provided in this Section 7.06 in connection with a distribution of non-cash assets pursuant to Section 5.02.

(b) Notwithstanding the foregoing, in connection with a proposed distribution of non-cash assets pursuant to Section 5.02 (each, a “Fair Market Value Disposition”), Vistra Member shall deliver written notice to the Class B Member Representative of its determination of the Fair Market Value of the non-cash assets to be distributed in such Fair Market Value Disposition, together with reasonable supporting documentation therefor (the delivery of such notice, the “Triggering Event”). Such determination of Fair Market Value in the notice delivered pursuant to this Section 7.06(b) shall become conclusive, final and binding for all purposes on the date that is ten (10) Business Days after the Triggering Event, unless Vistra Member receives a written notice of disagreement (the “Notice of Disagreement”) from the Class B Member Representative prior to such date. The Notice of Disagreement shall specify in reasonable detail the nature and basis of any such disagreement. During the first ten (10) Business Days after which Vistra Member receives the Notice of Disagreement (such ten (10) Business Day period, the “Resolution Period”), Vistra Member and the Class B Member Representative shall attempt in good faith to resolve any differences that they may have with respect to the determination of such Fair Market Value.

46

(c) If Vistra Member and the Class B Member Representative have not reached agreement on the determination of such Fair Market Value by the expiration of the Resolution Period (or earlier by mutual agreement), then Vistra Member and the Class B Member Representative shall, as promptly as reasonably practicable, but in no event later than five (5) Business Days after the expiration of the Resolution Period (such five (5) Business Day period, the “Selection Period”), jointly select (acting reasonably in such selection) an available independent investment banking firm of national standing (the “Valuation Firm”) and notify the Company of its selection. If Vistra Member and the Class B Member Representative are unable to agree on a Valuation Firm prior to the expiration of the Selection Period, then within two (2) Business Days after the expiration of the Selection Period, each of Vistra Member and the Class B Member Representative shall select one available independent investment banking firm of national standing and those two firms shall, within five (5) Business Days after their selection, select a third available independent investment banking firm of national standing to serve as the Valuation Firm. The Company shall engage the Valuation Firm to determine, acting as an appraiser, on behalf of Vistra Member and the Class B Member Representative, the Fair Market Value (in accordance with this Section 7.06) of the Class B Units within thirty (30) days after its engagement, which determination shall include a work sheet setting forth all material calculations and corresponding explanations used by the Valuation Firm in arriving at such determination. The determination of the Valuation Firm of such Fair Market Value shall be conclusive, final and binding for all purposes in connection with the applicable Fair Market Value Disposition. The fees and costs of the Valuation Firm will be borne by Vistra Member if the Valuation Firm’s determination of Fair Market Value is more than ten percent (10%) greater than the Fair Market Value as set forth in the applicable notice giving rise to the applicable Triggering Event and otherwise shall be borne by the Class B Members.

(d) None of Vistra Member, any Class B Member nor the Class B Member Representative shall have any ex parte communications with the Valuation Firm.

(e) From and after the Triggering Event and prior to the final determination of Fair Market Value hereunder, the Company shall give Vistra Member and the Class B Member Representative and their respective advisors and representatives, upon prior notice, reasonable access during normal business hours to the Company’s books and records as Vistra Member, the Class B Member Representative or either of their respective advisors or representatives may from time to time reasonably request in order to evaluate the Fair Market Value of the non-cash assets proposed to be distributed in accordance herewith; provided, however, that any such access shall be (i) conducted in a manner not to interfere unreasonably with the businesses or operations of the Company or any of its Subsidiaries, and (ii) under the supervision of appropriate personnel; provided, further, that the Class B Members shall promptly reimburse the Company for any reasonable out-of-pocket expenses incurred by the Company or any of its Subsidiaries arising out of affording any such access. Notwithstanding the immediately preceding sentence, neither the Company nor any of its Subsidiaries shall be required to afford access or furnish information to the extent (x) such information is subject to the terms of a confidentiality obligation with a third party or (y) the Company reasonably determines in good faith that affording such access or furnishing such information would (A) result in the disclosure of trade secrets of third parties, (B)

47

cause competitive harm to the Company or its Subsidiaries, (C) expose the Company to risk of liability under data protection Laws for disclosure of personal information, (D) jeopardize the attorney-client or other privilege of the Company or any of its Subsidiaries or (E) violate applicable Law. Nothing in this Section 7.06(e) will be construed to require the Company or its Subsidiaries or any of their respective representatives to prepare any reports, analyses, appraisals, opinions or other information.

ARTICLE 8

TAXES

8.01 Tax Status of the Company. The Company shall be classified as an association taxable as a corporation for U.S. federal tax purposes. In furtherance of the foregoing, the Company shall file a timely and duly executed election on Internal Revenue Service Form 8832 to be classified as an association taxable as a corporation for U.S. federal tax purposes, effective as of no later than the day preceding the Effective Date.

8.02 Intended Tax Treatment.

Each of the Members shall use its respective best efforts, and shall cause their respective Affiliates to use their respective best efforts, to take or cause to be taken any action within their respective control necessary for the EH Stock Contributions and the Vistra Contribution to qualify for the Intended Tax Treatment, and no Member (nor any of its Affiliates) has knowledge of any facts, agreements, plans or other circumstances, or has taken or agreed to take any action, that could reasonably be expected to prevent or impede the EH Stock Contributions or the Vistra Contribution from qualifying for the Intended Tax Treatment. Each of the Members shall file, and shall cause their respective Affiliates to file, all tax returns consistent with the Intended Tax Treatment except to the extent otherwise required by a “determination” within the meaning of Section 1313(a) of the Code (or any similar provision of state, local or foreign law, as appropriate) or a change in applicable Law. The Members agree that this Section 8.02 shall supersede Section 5.13(b)(ii) of the Transaction Agreement which shall, as among the Members and their respective Affiliates, have no further force or effect.

8.03 Indemnification for Certain Taxes. Notwithstanding anything to the contrary in this Agreement, Vistra Member shall indemnify, defend and hold harmless the Company from and against any and all taxes imposed on the Company or any of its Subsidiaries (and any penalties and interest with respect thereto), solely to the extent arising out of or resulting from (a) the VZ Contribution (as defined in the Transaction Agreement) and (b) any Vandalia Zero Entity (as defined in the Transaction Agreement) having been, prior to the Effective Date, a member of any consolidated group pursuant to Treasury Regulations Section 1.1502-6 (or any similar provision of state, local or non-U.S. Law) of which Vistra Member or any of its Affiliates was the parent but, in the case of this clause (b), solely to the extent that such Vandalia Zero Entity or Vandalia Zero Entities would not have been liable for such tax had such tax been calculated with respect to a consolidated group the only parties to which were Vandalia Zero Entities.

10.03 Courts.

Each of the parties hereto irrevocably submits to the exclusive jurisdiction of, and agrees not to commence any action, suit, or proceeding relating to a Dispute except in, the Delaware Courts and hereby consents to service of process in any such Dispute by the delivery of such process to such party at the address and in the manner provided in Section 12.01.

50

be construed to diminish or otherwise impair in any respect any Member’s or the Company’s right to specific performance, and (c) the right of specific performance is an integral part of the transactions contemplated by this Agreement and without that right none of the parties hereto would have entered into this Agreement.

ARTICLE 11

DISSOLUTION, WINDING-UP AND TERMINATION

11.01 Dissolution. The Company shall dissolve and its affairs shall be wound up on the first to occur of the following events (each a “Dissolution Event”):

(a) the consent of the Managing Member, subject to Section 6.03 (if applicable); or

(b) at any time there are no Members, unless the Company is continued without dissolution in accordance with the Act.

Each Member hereby waives its right to make an application for the dissolution of the Company pursuant to Section 18-802 of the Act.

11.02 Winding-Up and Termination.

(a) On the occurrence of a Dissolution Event, the Managing Member shall, or shall promptly designate a Person to, serve as liquidator (the “Liquidator”). The Liquidator shall proceed diligently to wind up the affairs of the Company in an orderly manner and make final distributions as provided herein and in the Act. The costs of winding-up shall be borne as a Company expense. Until final distribution, the Liquidator shall continue to operate the Company properties with all of the power and authority of the Members. The steps to be accomplished by the Liquidator are as follows:

(i) the Liquidator shall discharge from Company funds all of the debts, liabilities, expenses, and obligations of the Company (including all expenses incurred in winding-up) or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent, conditional or unmatured liabilities in such amount and for such term as the Liquidator may reasonably determine); and

51

(ii) all remaining assets of the Company shall be distributed to the Members as follows:

(A) the Liquidator may sell any or all Company property, including to Members (including the Managing Member) for Fair Market Value; and

(B) Company property (including cash) shall be distributed among the Members in accordance with Section 5.02. If a distribution under this Section 11.02 is in property other than cash, the value of such distribution shall be deemed to be the Fair Market Value of such property. A distribution in kind of an asset to a Member shall be deemed, for the purposes of this Article 11, a distribution in an amount equal to the Fair Market Value of the assets so distributed.

(b) The distribution of cash or property to a Member in accordance with the provisions of this Section 11.02 constitutes a complete return to the Member of its Capital Contributions and a complete distribution to the Member of its interest in the Company and all the Company’s property and constitutes a compromise to which all Members have consented pursuant to Section 18-502(b) of the Act. To the extent that a Member returns funds to the Company, it has no claim against any other Member for those funds.

(c) No dissolution or termination of the Company shall relieve a Member from any obligation to the extent such obligation has accrued as of the date of such dissolution or termination.

11.03 Certificate of Cancellation. On completion of the distribution of Company assets as provided herein, the Managing Member shall file a certificate of cancellation with the Secretary of State of the State of Delaware, cancel any other filings made pursuant to Section 2.06, and take such other actions as may be necessary to terminate the existence of the Company. Upon the filing of such certificate of cancellation, the existence of the Company shall terminate (and the Term shall end), except as may be otherwise provided by the Act or other applicable Law.

Each of this Agreement and the Delaware Certificate may, subject to Section 6.02(a), be amended or restated, and any provision hereof may be waived, only by a written instrument executed (or, in the case of the Delaware Certificate, approved) by the Managing Member.

If any provision of this Agreement or the application thereof to any party hereto or circumstance is held invalid or unenforceable to any extent by a court of competent jurisdiction, (a) the remainder of this Agreement and the application of that provision to other parties hereto or circumstances is not affected thereby, and (b) the parties hereto shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the parties hereto in substantially the same economic, business, and legal position as they would have been in if the original provision had been valid and enforceable.
