(A) Such disposition (i) of Interests to a third-party purchaser that is not another TGE Acquiror shall only be effected, and (ii) of Interests to a purchaser that is another TGE Acquiror, to the greatest extent possible (but without adversely impacting the economics of any other TGE Investor), shall be effected as follows:

(1) first, the applicable TGE Acquiror distributing the Interests, subject to a pro-rata portion of any outstanding Debt Financing (based on the aggregate number of Interests sold in such Direct Sale relative to the total number of Interests held by the TGE Acquirors, the “Applicable Direct Sale Debt Financing”), to applicable TGE Holdco;

Notwithstanding the foregoing, Enagas Investor shall not be entitled to effect a Direct Sale of its Interests held through the Non-ECI Silo Entities without the prior written consent of GIC Investor.

(B) However, if the structure outlined in Section 4.2(c)(i)(A) is not achievable after the use of commercially reasonable efforts, the TGE Investors agree to cooperate regarding the execution and documentation of such Direct Sale and use commercially reasonable efforts to effect such transactions in a manner that does not subject another TGE Investor (other than the requesting Co-Investor) to any material adverse income tax or adverse economic consequences as a result of such Direct Sale, including by utilizing tax allocations and other items of income, gain, loss and deduction to cause any such gain from a sale or disposition to be allocated or economically borne by the selling party. Unless an alternative structure is agreed upon pursuant to this Section 4.2(c)(i)(B), such Direct Sale shall be reported in a manner that does not allocate any gain or loss to any TGE Investor other than the TGE Investor requesting the Direct Sale and effected as follows:

(1) first, the proposed third-party purchaser purchasing such Interests from ECI Acquiror;

(2) second, ECI Acquiror repaying the Applicable Direct Sale Debt Financing;

(3) third, ECI Acquiror distributing the net proceeds after such debt repayment to applicable TGE Holdco;

(4) fourth, the applicable TGE Holdco distributing such net proceeds to the applicable TGE Aggregator; and

(5) fifth, the applicable TGE Aggregator redeeming a number of Aggregator LP Units held by the applicable Co-Investor in the same proportion as the Interests sold in such Direct Sale represent to the total number of Interests that were indirectly held by such Co-Investor through the applicable TGE Aggregator immediately prior to the Direct Sale (on a look-through basis).

(ii) If such Direct Sale is effected from the holdings of Non-ECI Acquiror such Direct Sale shall be reported in a manner that does not allocate any gain or loss to any TGE Investor other than the TGE Investor requesting the Direct Sale (the “Non-ECI Gain Reporting”) and effected as follows:

(A) first, the proposed third-party purchaser purchasing such Interests from Non-ECI Acquiror;

(B) second, Non-ECI Acquiror repaying the Applicable Direct Sale Debt Financing;

30

(C) third, Non-ECI Acquiror distributing the net proceeds after such debt repayment to Non-ECI Holdco;

(D) fourth, Non-ECI Holdco distributing such net proceeds to Non-ECI Aggregator; and

(E) fifth, Non-ECI Aggregator redeeming a number of Aggregator LP Units held by the applicable Co-Investor in the same proportion as the Interests sold in such Direct Sale represent to the total number of Interests that were indirectly held by such Co-Investor through Non-ECI Aggregator immediately prior to the Direct Sale (on a look-through basis).

(iii) If such Direct Sale is effected from the holdings of Secondary Acquiror or any other entity through which two or more TGE Investors invest (other than Non-ECI Acquiror) (but only if Secondary Acquiror or such other entity is not then burdened by debt, it being understood that if Secondary Acquiror or such other entity is burdened by debt then the provisions of Section 4.2(c)(ii) or Section 4.2(c)(i) shall apply mutatis mutandis to the procedures for such disposition, as may be agreed by the Parties in the organizational documents of such entity):

(A) first, redeeming a number of Secondary Acquiror LP Units held by the applicable Co-Investor in the same proportion as the Interests to be sold in such Direct Sale represent to the total number of Interests that were indirectly held by such Co-Investor immediately prior to the Direct Sale (on a look-through basis) in exchange for the Interests to be sold in such Direct Sale; and

(B) second, causing such Co-Investor to sell such Interests to the proposed third-party purchaser.

(iv) BIP Q LP shall indemnify Enagas Investor for any tax liability, including any interest and penalties related thereto, imposed on Enagas Investor as a direct result of any challenge by the U.S. Internal Revenue Service to the Non-ECI Gain Reporting.

In the event of a Direct Sale in which Interests are distributed to any Co-Investor, such TGE Acquiror shall Transfer any and all applicable registration rights with respect to such Interests that such TGE Acquiror may have pursuant to any contract or other arrangement to such Co-Investor.

(d) In the case of a Topco Sale or a Direct Sale and to the extent permitted by this Section 4.2, the Parties shall amend this Agreement or enter into a new equityholders’ agreement granting the purchaser in any such Topco Sale or Direct Sale any rights of a Co-Investor that have been transferred to such purchaser in connection with such sale pursuant to the terms of this Section 4.2. Each member of the TGE Group, Aggregator GP, the Closing Silo Entities and GP Acquiror shall reasonably cooperate with such Co-Investor and assist such Co-Investor (i) in connection with a Direct Sale or Topco Sale, as applicable, including executing, acknowledging and delivering assignments and other documents or instruments as may be reasonably requested by, and otherwise cooperating reasonably with, such Co-Investor and the proposed purchaser (including requiring any member of the TGE Group and each of Aggregator GP, the Closing Silo Entities and GP Acquiror, if requested in connection with a Direct Sale and if any member of the TGE Group is a publicly traded entity, to exercise their available demand registration rights under the existing registration rights agreement to effect an underwritten offering) and (ii) in connection with any Direct Sale or Topco Sale, but not more than once in any twelve (12)-month period and at such Co-Investor’s sole cost and expense of any third-party costs or expenses incurred, (A) reasonably assist with the preparation and delivery by such Co-Investor of preliminary marketing and auction materials, (B) prepare or reasonably assist in the preparation of due diligence materials, (C) make such due diligence materials available to prospective purchasers, (D) provide reasonable access to each of their respective

31

books, records, properties and other proprietary materials (subject, in each case, to the execution of customary confidentiality and non-disclosure agreements) to prospective purchasers and (E) make the managers, officers and employees reasonably available to prospective purchasers for presentations and due diligence interviews.

(e) Debt Funding Restrictions. The Parties acknowledge that the Credit Agreement or the terms governing any other Debt Financing may prohibit a Direct Sale. In connection with any Direct Sale requested by a Co-Investor, Aggregator GP and the TGE Acquirors shall use good faith commercially reasonable efforts to seek and obtain the required consents and/or waivers from the applicable lenders and other holders of such Debt Financing as shall be required to permit such Direct Sale. To the extent any such consent or waiver is conditioned on a payment of consent fees or other consideration in connection therewith (other than customary fees of counsel), the applicable Co-Investor shall pay, or cause to be paid, such consideration. In addition, in connection with any refinancing of any Debt Financing (including the Initial Term Loans under and as defined in the Credit Agreement) the terms of which may limit or restrict the ability to effect Direct Sales in accordance with Section 4.2(c) above, Aggregator GP and the TGE Acquirors shall use good faith commercially reasonable efforts to cause the terms of such refinancing debt to permit Direct Sales.

(f) Notwithstanding any provision hereof or of the Non-ECI Aggregator LPA or of the ECI Aggregator LPA to the contrary, without the prior consent of Aggregator GP, no Co-Investor Transfer and no Transfer by the BIP Funds of their Interests may be effected if such Transfer would:

(i) violate any U.S. federal, state and other applicable laws, including any U.S. federal, state and other securities laws applicable to any Closing Silo Entity and the Interests;

(ii) cause any Closing Silo Entity to become subject to the registration and/or qualification requirements of the Investment Company Act, the Exchange Act, the Securities Act or any other applicable securities laws of any jurisdiction;

(iii) pose a material risk that any Closing Silo Entity would be treated as a “publicly” traded partnership, as such term is defined in Sections 469(k)(2) or 7704 of the Code and related Treasury Regulations; or

(iv) cause (a) all or any portion of the assets of a Closing Silo Entity (1) to constitute “plan assets” (for purposes of Title I of ERISA, Section 4975 of the Code or the applicable provision of any similar law) or any existing or prospective member or (2) to be subject to the provisions of Title I of ERISA, Section 4975 of the Code or any similar law or (b) any BIP Fund to become a fiduciary with respect to any existing or prospective member of a Closing Silo Entity, pursuant to ERISA or the applicable provisions of any similar law or otherwise.

(g) Any Transfer by a Co-Investor shall satisfy the BIP Funds’ anti-money laundering and “know your client” procedures.

(h) No Transfer by a Co-Investor and no Transfer by the BIP Funds of their Interests shall effect a release of such Co-Investor (or its applicable Affiliates) or the BIP Funds and their Affiliates from any liabilities or obligations to any of the other Parties hereto or any of their respective Affiliates that accrued prior to such Transfer.

32

Section 4.3 Acceptable GP Transfers to Additional Investors. To the extent that any BIP Fund arranges for additional Persons (“Additional Investors”) to purchase Class A Shares either (i) after the expiration of the Secondary Purchase Period or (ii) during the Secondary Purchase Period in purchases that are not Agreed Purchases, Aggregator GP shall have the right (without the consent of GIC Investor, Enagas Investor or any other Person) to cause the TGE Acquirors to sell Equity Interests in GP Acquiror from the holdings of the TGE Acquirors to any such Additional Investor at the GP Acquiror Purchase Price in cash (such Transfers, “Acceptable GP Transfers”); provided that all such sales of Equity Interests in GP Acquiror shall be proportionate to the number of Class A Shares purchased by such Additional Investors, such that the percentage of the total outstanding Equity Interests in GP Acquiror held by any Additional Investor shall not exceed the Ownership Percentage of such Additional Investor; and provided, further, that all such sales shall occur substantially concurrently with such purchase or as soon as reasonably practicable thereafter (but in no event later than 30 days thereafter); provided, that if any Acceptable GP Transfers occur as a result of purchases of Class A Shares at a per share price exceeding the Specified Price and have the effect of diluting Enagas Investor’s ownership of outstanding Equity Interests of GP Acquiror (on a look-through basis), all thresholds related to Enagas Investor’s ownership of outstanding Equity Interests of GP Acquiror herein shall be proportionately reduced.

Section 4.4 Drag-Along Rights.

(a) Subject to Section 4.7, a Drag-Along Transaction may be initiated in compliance with this Section 4.4 at any time by Aggregator GP (but, if the BIP Funds and their Affiliates own, on a look-through basis, less than 50% of the Equity Interests of GP Acquiror, only with the consent and approval of the Holders of more than 50% of the Equity Interests of GP Acquiror on a look-through basis); provided, however that any Drag-Along Transaction described in clause (b) of the definition of “Exit Transaction” shall also require the consent of GIC Investor and Enagas Investor provided, further, however, that the BIP Funds have used good faith efforts to negotiate with the proposed purchaser in order to allow Enagas Investor and GIC Investor to retain their Interests in any such Drag-Along Transaction (and such efforts shall include permitting GIC Investor and Enagas Investor to directly meet with the proposed purchaser solely to discuss such retention of Interests and post-closing governance rights). If Aggregator GP elects to effect a Drag-Along Transaction, Aggregator GP shall deliver written notice thereof to each Co-Investor.

(b) In connection with any Drag-Along Transaction properly initiated pursuant to Section 4.4(a), and subject to the terms and conditions set forth in this Section 4.4, each TGE Investor and its Affiliates shall consent to and raise no objections against the consummation of the Drag-Along Transaction, and if the Drag-Along Transaction is structured as: (i) a consolidation, merger or other business combination, or a sale or other disposition of all or substantially all of the assets of one or more Aggregator Entities (as defined below), each TGE Investor and its Affiliates, as applicable, shall vote in favor of the Drag-Along Transaction and shall waive any appraisal rights or similar rights in connection with such consolidation, merger, other business combination or asset sale or (ii) a sale of all or substantially all of the Interests, each TGE Investor and its Affiliates shall agree to sell all of its Interests that are the subject of the Drag-Along Transaction, on the terms and conditions of such Drag-Along Transaction. Subject to Section 4.4(c), each TGE Investor and its Affiliates shall promptly take all necessary and desirable actions in connection with the consummation of the Drag-Along Transaction reasonably requested by Aggregator GP and its Affiliates, including the execution of such agreements and such other instruments and the taking of such other actions reasonably necessary to (A) provide customary representations, warranties, indemnities, and escrow or holdback arrangements relating to such Drag-Along Transaction, and (B) effectuate the allocation and distribution of the aggregate consideration upon the Drag-Along Transaction. The TGE Investors shall be permitted to sell their Interests pursuant to any Drag-Along Transaction without complying with any other provisions of this Article IV other than this Section 4.4.

33

(c) The obligations of each TGE Investor pursuant to this Section 4.4 are subject to the following terms and conditions:

(i) the Drag-Along Transaction shall be effected on the same terms and conditions with respect to the BIP Funds and each TGE Investor (including that the consideration paid for each Class A Share sold (directly or indirectly) by each TGE Investor in any such Drag-Along Transaction shall (1) be the same as the consideration paid for each Class A Share sold by the BIP Funds and (2) be the same as the consideration paid for each Class B Interest sold by the BIP Funds);

(ii) the consideration paid in the Drag-Along Transaction shall consist entirely of cash or freely tradeable securities of an entity listed on a national securities exchange (as such term is used under the Exchange Act) and taxable as a subchapter c-corporation for U.S. income tax purposes;

(iii) upon the consummation of the Drag-Along Transaction, each TGE Investor shall receive the same proportion of the aggregate consideration from such Drag-Along Transaction that it would have received if such aggregate consideration had been distributed by the applicable Aggregator Entity in complete liquidation pursuant to the rights and preferences set forth in the applicable Aggregator Entity LPA as in effect immediately prior to such Drag-Along Transaction, and if each TGE Investor receives consideration from such Drag-Along Transaction in a manner other than as contemplated by such rights and preferences or in excess of the amount to which such holder is entitled in accordance with such rights and preferences, then the Parties shall take such action as is necessary so that such consideration shall be immediately reallocated among and distributed to each TGE Investor in accordance with such rights and preferences;

(iv) Non-ECI Aggregator, ECI Aggregator and VCOC Aggregator and any other entity that acquired interests in the TGE Group in accordance with Section 5.3(b) (each an “Aggregator Entity”) shall each bear its respective pro-rata portion of the reasonable, documented costs incurred in connection with any Drag-Along Transaction and each TGE Investor shall not be obligated to make any out-of-pocket expenditure in connection with the consummation of the Drag-Along Transaction (excluding modest expenditures for postage, copies, and the like) that is more than its pro rata share (based upon the amount of consideration received by it in the Drag-Along Transaction) of reasonable expenses incurred in connection with a consummated Drag-Along Transaction for the benefit of all Holders that are not otherwise paid by the applicable Aggregator Entity or another Person;

(v) no TGE Investor shall be required to provide any representations, warranties or indemnities under any agreements entered into in connection with the Drag-Along Transaction, other than customary (including with respect to qualifications) several (and not joint) representations, warranties and indemnities concerning: (1) due organization, valid existence and good standing in its state of organization, (2) valid title to and ownership of its Interests, free and clear of all Liens (excluding those arising under applicable securities laws); (3) authority, power and right to enter into and consummate the Drag-Along Transaction; (4) the absence of any violation, default or acceleration of any agreement to which each TGE Investor is subject or by which its assets are bound as a result of the Drag-Along Transaction; and (5) the absence of, or compliance with, any governmental or third-party consents, approvals, filings or notifications required to be obtained or made by each TGE Investor in connection with the Drag-Along Transaction, other than under the HSR Act;

(vi) no TGE Investor shall be required to provide any post-closing non-competition, non-solicitation or other similar restrictive covenants (other than customary confidentiality covenants) under any agreements entered into in connection with the Drag-Along Transaction;

(vii) no TGE Investor shall be obligated to provide any indemnification or otherwise agree to be liable to the purchaser in any such Drag-Along Transaction for representations and warranties pertaining to any of Aggregator GP, any Closing Silo Entity, GP Acquiror and its Subsidiaries or any member of the TGE Group unless any such indemnification obligations are several and not joint and such indemnification and liability is (x) limited in the aggregate to no more than the amount of consideration received by such TGE Investor from such Drag-Along Transaction and (y) on a pro-rata basis in proportion to the consideration received by the TGE Investors; and

34

(viii) consideration placed in escrow or held back shall be allocated to each TGE Investor such that if the applicable third party in the Drag-Along Transaction ultimately is entitled to some or all of such escrow or holdback amounts, then the net ultimate proceeds received by such holders shall still comply with the intent of Section 4.4(c)(i) as if the ultimate resolution of such escrow or holdback had been known at the closing of the Drag-Along Transaction.

(d) Aggregator GP and its Affiliates shall have the right in connection with any prospective Drag-Along Transaction (or in connection with the investigation or consideration of any prospective Drag-Along Transaction) to require each TGE Investor and each Aggregator Entity to cooperate fully with potential acquirors in such prospective transaction by taking all customary and other actions reasonably requested by such Persons or such potential acquirors, subject to reasonable and customary confidentiality provisions. In addition, Aggregator GP and its Affiliates shall be entitled to take all steps reasonably necessary to carry out an auction of any applicable Aggregator Entity, including selecting an investment bank, providing confidential information (pursuant to confidentiality agreements), selecting the winning bidder and negotiating the requisite documentation.

(e) Notwithstanding the foregoing, or anything else to the contrary in this Agreement or the other Transaction Documents, any Exit Transaction (including a Drag-Along Transaction) shall be effected solely through a transaction which would not result in corporate-level taxation borne (directly or indirectly) by GIC Investor.

(f) For the avoidance of doubt, GIC Investor shall be entitled to retain its Interests and its rights under this Agreement and the other Transaction Documents in any Exit Transaction that does not constitute a GIC Qualifying Sale and Enagas Investor shall be entitled to retain its Interests and its rights under this Agreement and the other Transaction Documents in any Exit Transaction that does not constitute an Enagas Qualifying Sale.

Section 4.5 Tag-Along Rights.

(a) If any BIP Fund or any of its Affiliates (each, in such capacity, a “Tag Subject Member”) desires to Transfer, directly or indirectly, all or any portion of its direct or indirect Equity Interests in GP Acquiror, TGE GP, any Closing Silo Entity or in any member of the TGE Group to any Person (a “Tag Transferee”, which for the avoidance of doubt, includes any Purchasing Member pursuant to Section 4.7) (whether pursuant to a merger, sale of Equity Interests or similar transaction and whether effected through an indirect transaction by any of the Closing Silo Entities or GP Acquiror), other than through a Transfer permitted under Section 4.1(a)(i) (Permitted Transfers) and (ii) (Drag-Along Transactions), such Tag Subject Member shall first offer to include in such proposed Transfer (the “Tag-Along Sale”), in addition to all Equity Interests that the Tag Subject Member desires to Transfer, GIC Investor’s and Enagas Investor’s proportionate share of equivalent Equity Interests owned, whether directly or indirectly, and designated by GIC Investor or Enagas Investor, as applicable (each, a “Tag Eligible Member”) in accordance with the terms of this Section 4.5 (the “Eligible Units”), subject to the following terms and conditions:

(i) the Tag-Along Sale by the Tag Eligible Member shall be on the same terms and conditions as are applicable to the Tag Subject Member including that (A) the consideration paid for each Class A Share sold (directly or indirectly) by such Tag Eligible Member shall (1) be the same as the consideration paid for each Class A Share sold by the Tag Subject Member and (2) be the same as the

35

consideration paid for each Class B Interest sold by the Tag Subject Member and (B) the consideration paid for each Class B Interest sold (directly or indirectly) by such Tag Eligible Member shall (1) be the same as the consideration paid for each Class A Share sold by the Tag Subject Member and (2) be the same as the consideration paid for each Class B Interest sold by the Tag Subject Member;

(ii) each Tag Eligible Member shall have the right to (A) Transfer the same percentage of the Class A Shares it indirectly holds (on a look-through basis) as is equal to the percentage of Class A Shares and Class B Interests that the Tag Subject Member is selling of its total holdings of Class A Shares and Class B Interests and (B) the same percentage of the Acquired GP Interests it indirectly holds (on a look-through basis) as is equal to the percentage of Acquired GP Interests that the Tag Subject Member is selling of its total holdings of Acquired GP Interests in such transaction;

(iii) no Tag Eligible Member shall be required to provide any representations, warranties or indemnities under any agreements entered into in connection with the Tag-Along Sale, other than customary (including with respect to qualifications) several (and not joint) representations, warranties and indemnities concerning: (1) due organization, valid existence and good standing in its state of organization, as applicable, (2) valid title to and ownership of the Eligible Units, free and clear of all Liens (excluding those arising under applicable securities laws); (3) authority, power and right to enter into and consummate the Tag-Along Sale; (4) the absence of any violation, default or acceleration of any agreement to which such Tag Eligible Member is subject or by which its assets are bound as a result of the Tag-Along Sale; and (5) the absence of, or compliance with, any governmental or third-party consents, approvals, filings or notifications required to be obtained or made by such Tag Eligible Member in connection with the Tag-Along Sale, other than under the HSR Act;

(iv) no Tag Eligible Member shall be required to provide any post-closing non-competition, non-solicitation or other similar restrictive covenants (other than customary confidentiality covenants) under any agreements entered into in connection with the Tag-Along Sale (without, for the avoidance of doubt, limiting the enforceability of any such covenants existing prior to such Tag-Along Sale); and

(v) no Tag Eligible Member shall be obligated to provide any indemnification or otherwise agree to be liable to the Tag Transferee in any such Tag-Along Sale for representations and warranties pertaining to any of Aggregator GP, any Closing Silo Entity, GP Acquiror and its Subsidiaries or any member of the TGE Group unless any such indemnification obligations are several and not joint and such indemnification and liability is (x) limited in the aggregate to no more than the amount of consideration received by such Tag Eligible Member from such Tag-Along Sale and (y) on a pro-rata basis in proportion to the consideration received by the TGE Investors.

(b) The Tag Subject Member shall cause the offer from such Tag Transferee (the “Tag-Along Offer”) to be reduced to writing, which writing shall include: (i) an offer to purchase or otherwise acquire the Eligible Units from the Tag Eligible Member as required by this Section 4.5; (ii) a time and place designated for the closing of such purchase; and (iii) the per Equity Interest purchase price for the Eligible Units.

(c) The Tag Subject Member shall send written notice of such Tag-Along Offer (a “Tag-Along Offer Notice”), to the Tag Eligible Member as soon as reasonably practicable. The Tag Eligible Member shall have the right (an “Inclusion Right”), exercisable by delivery of written notice to the Tag Subject Member at any time within twenty (20) Business Days after receipt of the Tag-Along Offer Notice, to request to sell in the Tag-Along Sale all or any portion of the Eligible Units (together with the Equity Interests proposed to be sold by the Tag Subject Member, the “Requested Units”). Failure of a Tag Eligible Member to timely notify the Tag Subject Member that it elects to cause the Tag Transferee to purchase the Tag Eligible Member’s Eligible Units shall be deemed an election by such Tag Eligible Member not to cause the Tag Transferee to purchase such Eligible Units. A Tag Eligible Member that timely exercises its Inclusion Right is referred to as a “Tag Electing Member.”

36

(d) Promptly following the completion of the procedures described in Section 4.5(c), the Tag Subject Member shall determine whether the Tag Transferee is willing to purchase all of the Requested Units. If the Tag Transferee is willing to purchase all of the Requested Units, then the Tag Transferee shall purchase such Requested Units in accordance with this Section 4.5 (such Requested Units, “Purchased Units”). If the Tag Transferee is unwilling to purchase all of the Requested Units, then the Tag Subject Member shall determine the maximum number of Requested Units that the Tag Transferee is willing to purchase (the “Maximum Purchased Units”). The quotient (expressed as a percentage) of (x) the Maximum Purchased Units, divided by (y) the Requested Units shall be the “Purchased Percentage.” Following the foregoing determination, the Tag Subject Member and the Tag Electing Member shall sell in the Tag-Along Sale a number of Equity Interests equal to (1) the Requested Units of the Tag Subject Member or such Tag Electing Member, as applicable, multiplied by (2) the Purchased Percentage (such Equity Interests, collectively, also “Purchased Units”).

(e) If some or all of the consideration proposed to be paid by a third party to the Tag Subject Member in a Tag-Along Sale is other than cash, then such consideration shall be deemed to have a dollar value equal to the Fair Market Value, and all holders of Purchased Units shall be entitled to receive the same form of consideration in respect of such Purchased Units in the same proportions.

(f) At the time (subject to extension to the extent necessary to pursue any required regulatory or equityholder approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) and place provided for the closing in the Tag-Along Offer, or at such other time and place as the Tag Subject Member and the Tag Transferee shall agree, the Tag Subject Member and the Tag Electing Members shall sell to the Tag Transferee all of the Purchased Units. Each sale of Purchased Units pursuant to this Section 4.5(f) shall be upon terms and conditions, if any, not more favorable individually and in the aggregate to the Tag Transferee than those in the Tag-Along Offer and the Tag-Along Offer Notice and upon the consummation of such sale, each holder of Purchased Units shall receive the consideration specified in Section 4.5(g).

(g) Upon the consummation of a Tag-Along Sale, each holder of Purchased Units shall receive in respect of each Purchased Unit an amount of consideration equal to the applicable Per Unit Purchase Price calculated to reflect the allocation of the consideration in Section 4.5(a)(i). If a transferor of Purchased Units receives consideration from such Tag-Along Sale in a manner other than as contemplated by the immediately preceding sentence or in excess of the amount to which such transferor is entitled in accordance with the immediately preceding sentence, then the Parties shall take such action as is necessary so that such consideration shall be immediately reallocated among and distributed to the transferors of Purchased Units in accordance with the immediately preceding sentence.

(h) If (i) a Tag-Along Sale is not consummated within ninety (90) days after delivery of the Tag-Along Offer Notice (which period may be extended to the extent reasonably necessary to pursue any required regulatory approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act), (ii) the Per Unit Purchase Price applicable to such Tag-Along Sale is increased from that resulting from the Tag-Along Offer and the allocation of the consideration resulting therefrom specified in Section 4.5(g) or (iii) the other terms and conditions applicable to such Tag-Along Sale change, individually or in the aggregate, in any material respect from those described in the Tag-Along Offer, then the Equity Interests subject to this Section 4.5 may not be sold without the Tag Subject Member again complying in full with the provisions of this Section 4.5.

37

Section 4.6 Demand Initial Public Offering.

(a) At any time following a Take-Private Transaction, Aggregator GP (but, if the BIP Funds and their Affiliates own, on a look-through basis, less than 50% of the Equity Interests of GP Acquiror, only with the consent and approval of the Holders of more than 50% of the Equity Interests of GP Acquiror on a look-through basis) shall have the right to effect an Initial Public Offering. Upon delivery of notice of an intent to effect a Initial Public Offering to GIC Investor and Enagas Investor, each of GIC Investor and Enagas Investor shall cooperate and use their respective commercially reasonable efforts to facilitate the consummation of the Initial Public Offering, including, but not limited to, furnishing customary information regarding itself sufficient to complete the beneficial ownership table in any registration statement and satisfy customary and reasonable know-your-client requests of any underwriters; provided, however, no Initial Public Offering shall (i) be effected unless such Initial Public Offering is of Class A Shares or shares of a successor corporation to TGE or (ii) involve an Initial Public Offering of a Subsidiary of TGE.

(b) In the event an Initial Public Offering is effected, the issuer in such Initial Public Offering shall enter into a customary registration rights agreement with each of the TGE Investors and each other significant investor in the TGE Group at such time, which will provide for, among other matters, the following:

(i) three (3) long-form underwritten registrations for every $450 million of equity capital invested (directly or indirectly) by such TGE Investor or other significant investor in the Interests with customary undertakings (including customary indemnification) by the issuer and unlimited short-form underwritten registrations of each TGE Investor’s interests at the issuer’s expense, subject to pro rata priority among the TGE Investors and customary exceptions including minimum offering sizes;

(ii) customary “piggy-back” registration rights (with pro rata priority among the TGE Investors) with respect to demand registrations and TGE registrations (other than registrations in connection with any employee stock option or other benefit plan or registrations in connection with an exchange offer), subject to pro rata underwriter cutbacks;

(iii) for a period of two (2) years following the Initial Public Offering, sale coordination, including cooperation with respect to block trades and Rule 144 sales; and

(iv) expense reimbursement for counsel for each of the TGE Investors in connection with any such registration.

(c) In the event that following the Initial Public Offering, BIP and its Affiliates would own the same or less of the interests or shares of the issuer in such Initial Public Offering than Enagas Investor and its Affiliates, BIP and Enagas Investor shall negotiate in good faith to provide both BIP and its Affiliates and Enagas Investor and its Affiliates with proportionate representation on the board (or similar governing body) of the issuer in such Initial Public Offering, subject to any applicable exchange listing and governance requirements.

(d) BIP shall use commercially reasonable efforts to contribute the Equity Interests in any Blocker Entity of Enagas Investor or GIC Investor to the issuer in any Initial Public Offering; provided that such transaction would not result in any adverse economic, tax or marketing consequences to such issuer or any of the TGE Investors.

38

Section 4.7 Right of First Offer.

(a) If either of the ROFO Subject Members (the “Offering Member”) proposes to Transfer all or a portion of such Offering Member’s Interests, then such Offering Member shall deliver written notice (the “ROFO Notice”) to the other ROFO Subject Member. The date that the ROFO Notice is received by the other ROFO Subject Member shall constitute the “ROFO Notice Date.” The ROFO Notice shall set forth the number and class or series of Interests to be offered (the “ROFO Offered Interests”).

(b) The non-Transferring ROFO Subject Member (the “Purchasing Member”) shall have up to thirty (30) calendar days after the ROFO Notice Date (such 30^th day, the “ROFO Expiration Date”) to offer to purchase all, but not less than all, of the ROFO Offered Interests by delivering a written notice (the “ROFO Offer Notice”) to the Offering Member stating such Purchasing Member’s intent to purchase such ROFO Offered Interests specified in the ROFO Offer Notice, which ROFO Offer Notice shall include the proposed price per ROFO Offered Interest, all details of the payment terms and all other material terms and conditions of the proposed Transfer. Notwithstanding anything to the contrary herein, such ROFO Offer Notice may not contain provisions relating to any property of the Offering Member other than Interests held by such Offering Member or contemplate any consideration other than cash in United States dollars. The delivery of a ROFO Offer Notice under this Section 4.7 shall constitute an irrevocable commitment to purchase such ROFO Offered Interests. During a period of fifteen (15) days after receipt of the ROFO Offer Notice, the Offering Member may elect to accept or reject the offer in the ROFO Offer Notice by providing written notice to the Purchasing Member by the end of such fifteen (15) day period (and failure to timely provide such notice shall be deemed rejection of the offer). If the Offering Member accepts a ROFO Offer Notice, the Offering Member shall thereafter set a reasonable place and time for the closing of the purchase and sale of the ROFO Offered Interests, which shall be not less than forty-five (45) calendar days nor more than ninety (90) calendar days after the ROFO Notice Date (subject to extension to the extent necessary to pursue any required regulatory or other approvals) unless otherwise agreed by all of the parties to such transaction (such period, the “ROFO Closing Period”).

(c) The purchase price and terms and conditions for the purchase of the ROFO Offered Interests shall be the price and terms and conditions set forth in the applicable ROFO Offer Notice. Aggregator GP, any other applicable Closing Silo Entity, GP Acquiror and the Offering Member will promptly cooperate with any reasonable requests of any Purchasing Member for information regarding the ROFO Offered Interests.

(d) Notwithstanding the foregoing, if (i) the Purchasing Members fail to elect to purchase all of the ROFO Offered Interests on or prior to the ROFO Expiration Date or (ii) the closing of the purchase and sale of the ROFO Offered Interests is not consummated within the ROFO Closing Period (and the Offering Member has fully complied with the provisions of this Section 4.7) on the terms of purchase set forth in the ROFO Offer Notice, then in either case the Purchasing Members shall not have the right to purchase any of the ROFO Offered Interests and the applicable Offering Member may sell all, but not less than all, of the ROFO Offered Interests within 90 days after the ROFO Expiration Date. If the Offering Member timely rejects any ROFO Offer Notice that is timely delivered or any such offer expires in accordance with its terms, then the applicable Offering Member may, after providing the advance notice provided below, sell all, but not less than all, of the ROFO Offered Interests within 90 days after the ROFO Expiration Date, if the terms and conditions of such sale, when taken as a whole, are at least as favorable (as reasonably determined by the Offering Member and any Purchasing Member that has delivered a ROFO Offer Notice) to the terms and conditions set forth in any such ROFO Offer Notice, taken as a whole. The Offering Member shall provide each such Purchasing Member a summary of the pricing and other material terms of the sale offer under the preceding sentence that the Offering Member wishes to accept at least fifteen (15) days prior to the consummation of the sale of the ROFO Offered Interests. If the Offering Member and any such Purchasing Member determine that the terms and conditions of such proposed sale of ROFO Offered Interests to a third party by the Offering Member are not as favorable as the terms and conditions provided in the ROFO Offer Notice, taken as a whole, then the Offering Member shall sell to

39

such Purchasing Member, and such Purchasing Member shall purchase from the Offering Member, the ROFO Offered Interests on the terms and conditions set forth in the ROFO Offer Notice, with the closing of such transaction to occur no later than thirty (30) days following such determination (subject to extension to the extent necessary to pursue any required regulatory or equityholder approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act). If the ROFO Offered Interests are not Transferred to a third party within the applicable 90-day period, then the Offering Member may not sell any of the ROFO Offered Interests without again complying in full with the provisions of this Section 4.7.

Section 4.8 Blocker Entities. If an Exit Transaction is structured to include the Equity Interests of a Blocker Entity of the BIP Funds, BIP shall use commercially reasonable efforts to include the Equity Interests in any Blocker Entity of the Enagas Investor and GIC Investor in such Exit Transaction; provided, that such transaction would not result in any adverse economic, tax or marketing consequences to any of the TGE Investors.

Section 4.9 Cooperation and Secondary Acquiror. Notwithstanding anything to the contrary herein, the TGE Investors shall cooperate and use commercially reasonable efforts to structure any Take-Private Transaction or any other acquisition of Interests by the Closing Silo Entities or any other entity through which BIP or a TGE Investor invests in a tax-efficient manner to the TGE Investors, including by using commercially reasonable efforts to ensure that any Direct Sales or other disposition of Interests are structured in a tax efficient manner to such Investors (in accordance with the provisions of Section 4.1(e) and Section 4.2 of this Agreement), which, for the avoidance of doubt, may include the creation of multiple investment vehicles through which such TGE Investors invest. Consistent with the foregoing, the Parties shall effect a division of Secondary Acquiror into two separate investment vehicles comprised of BIP and the Enagas Investor, on the one hand, and BIP and the GIC Investor, on the other hand. Such division shall be effectuated as soon as practicable after the Closing, and in any event, prior to Secondary Acquiror purchasing any Class A Shares, and in all cases without adverse tax consequence to any of the TGE Investors. From and after the date of such division, the term Secondary Acquiror in this Agreement shall refer to both such investment vehicles. Aggregator GP shall use its reasonable best efforts to effect all transactions in Class A Shares and otherwise deal with both such vehicles on a pari-passu and pro-rata basis, allocating, to the maximum extent reasonably practicable, all transactions in Class A Shares across both such vehicles on a pro-rata basis.

ARTICLE V

PREEMPTIVE RIGHTS.

Section 5.1 Issuances by the TGE Group.

(a) Prior to any member of the TGE Group (such member the “Issuer”) issuing to any proposed purchaser (each, a “Proposed Purchaser”) any Equity Interests or options, debt securities or other rights to acquire Equity Interests or debt securities, whether through exchange, conversion or otherwise, (collectively with any Equity Interests in GP Acquiror acquired by such Proposed Purchaser, the “New Units”), other than New Units (i) issued as of the Effective Date, (ii) issued to new employees, (iii) issued as consideration for bona fide acquisitions of another Person or the business or assets of another Person (whether by merger, consolidation or similar business combination) or (iv) issued in connection with any split, dividend or similar recapitalization, for so long as a TGE Investor owns the Minimum Ownership Amount, such TGE Investor shall have the right to purchase, the number of New Units as provided in this Section 5.1.

40

(b) GP Acquiror shall cause the Issuer to give each TGE Investor at least ten (10) Business Days’ prior notice (the “First Notice”) of any proposed issuance of New Units, which notice shall set forth in reasonable detail the proposed terms and conditions thereof and shall offer to each TGE Investor the opportunity to purchase its proportionate share of such New Units (which proportionate share shall be based on such TGE Investor’s Ownership Percentage ) (such TGE Investor’s “Proportionate Share”) at the same price, on the same terms and conditions and at the same time as the New Units are proposed to be issued to or purchased by the Proposed Purchaser. If a TGE Investor wishes to exercise its preemptive rights, it must do so by delivering an irrevocable written notice (“Preemptive Exercise Notice”) (subject to the consummation of the issuance to or purchase by the Proposed Purchaser) to the Issuer within ten (10) Business Days after delivery of the First Notice, which notice shall state the dollar amount of New Units such TGE Investor would like to purchase up to a maximum amount equal to such TGE Investor’s Proportionate Share.

(c) Notwithstanding anything to the contrary in this Section 5.1, the TGE Investors will have the right to participate in issuances of New Units constituting debt securities only to the extent that the BIP Funds or any of their Affiliates, as applicable, participate in such acquisition of such New Units constituting debt securities.

(d) The Issuer may, in its reasonable discretion, impose such other reasonable and customary terms and procedures such as setting a closing date, rounding the number of Equity Interests covered by this Section 5.1 to the nearest whole Equity Interest and requiring customary closing deliveries in connection with any preemptive rights offering.

(e) In the event that any TGE Investor does not elect to purchase all of its Proportionate Share, the New Units which were available for purchase by such non-electing TGE Investor (the “Excess New Units”) shall automatically be deemed to be accepted for purchase by any TGE Investor who indicated in its Preemptive Exercise Notice a desire to participate in the purchase of New Units in excess of its Proportionate Share. Unless otherwise agreed by each of the TGE Investors participating in the purchase, each TGE Investor who indicated in its Preemptive Exercise Notice that it desired to purchase more than its Proportionate Share shall purchase a number of Excess New Units equal to the lesser of (i) the number of Excess New Units indicated in the Preemptive Exercise Notice, if any, and (ii) an amount equal to the product of (A) the number of Excess New Units and (B) a fraction, the numerator of which is the number of Interests held at such time by such TGE Investor and the denominator of which is the aggregate number of Interests held at such time by each of the TGE Investors participating in such purchase of Excess New Units (in each case, on a look-through basis).

(f) In the event and to the extent that, subsequent to the procedure set forth in Section 5.1(b), any New Units (including any Excess New Units) are not acquired by the TGE Investor entitled to subscribe for and purchase such New Units, the Issuer shall be free to issue such New Units to any other Person; provided, that (i) the price per New Unit at which such New Units are being issued to and purchased by such Person is not less than the purchase price per New Unit set forth in the First Notice and (ii) the other terms and conditions pursuant to which such Person purchases such New Units are not materially more favorable than the terms set forth in the First Notice. Any New Units not issued or sold within ninety (90) days after the date of the First Notice (provided, that such ninety (90)-day period may be extended up to an additional ninety (90) days to the extent necessary to obtain any filings or consents from any applicable Governmental Entity) shall again be subject to the provisions of this Section 5.1.

(g) For the avoidance of doubt, if any TGE Investor elects not to participate in such a sale described in this Section 5.1, such TGE Investor shall be diluted accordingly.

41

Section 5.2 Acquisitions of TGE Securities.

(a) Prior to the acquisition, including in connection with any Take-Private Transaction with respect to TGE, of any outstanding Equity Interests or debt securities of any member of the TGE Group or any of the Closing Silo Entities, other than Secondary Purchases, (the “Subject Interests”) by a TGE Investor (or its Affiliates) (the “Acquiring Party”), including, for the avoidance of doubt, any such acquisition effected through any of the Closing Silo Entities, for so long as any other TGE Investor owns the Minimum Ownership Amount, each other TGE Investor shall have the right to purchase, the number of Subject Interests as provided in this Section 5.2; provided that for purposes of this Section 5.2(a), the term “Affiliate” means, with respect to GIC Investor, only Affiliates managed by GIC Special Investments Pte. Ltd.

(b) The Acquiring Party shall give the other TGE Investors at least ten (10) Business Days’ prior notice (the “Acquisition Notice”) of any proposed acquisition of Subject Interests, which notice shall set forth in reasonable detail the proposed terms and conditions thereof and shall offer to the other TGE Investors the opportunity to purchase their respective Proportionate Share of such Subject Interests at the same price, on the same terms and conditions and at the same time as the Acquiring Party proposes to acquire the Subject Interests. If a TGE Investor wishes to exercise its preemptive rights under this Section 5.2, it must do so by delivering an irrevocable written notice (subject to the consummation of the purchase of the Subject Interests) to the Acquiring Party within ten (10) Business Days after delivery of the Acquisition Notice, which notice shall state the dollar amount of Subject Interests such TGE Investor would like to purchase up to a maximum amount equal to such TGE Investor’s Proportionate Share.

(c) For the avoidance of doubt, the TGE Investors shall each be entitled to participate in any Take-Private Transaction up to its respective pro-rata interests in accordance with its Ownership Percentage. Each of the TGE Investors acknowledges that a Take-Private Transaction may be materially dependent upon the provision of committed equity and debt financing and as such, each TGE Investor agrees that such TGE Investor’s participation may be conditioned upon such TGE Investor’s entry into an equity commitment letter for such TGE Investor’s portion of such Take-Private Transaction and prompt response following notice of the final price and other material terms of such Take-Private Transaction.

(d) If the BIP Funds participate in a Take-Private Transaction, the BIP Funds shall exercise their reasonable best efforts to ensure that Enagas Investor is able to participate in such Take-Private Transaction in order to maintain at least a 20% Ownership Percentage (the “Target Take-Private Ownership Percentage”). If Enagas Investor is unable to participate in such Take-Private Transaction to maintain the Target Take-Private Ownership Percentage or to meet the Full Participation Condition, as applicable, solely to the extent such prohibition is due to a delay in receipt of Enagas Shareholder Approval, then, following the receipt of Enagas Shareholder Approval, the BIP Funds shall use good faith efforts to offer to Enagas Investor a right to purchase a number of Class A Shares that it was unable to purchase without Enagas Shareholder Approval at the Enagas Purchase Price (the “Purchase Option”). In the event the BIP Funds are unable to offer Enagas Investor a Purchase Option, Enagas Investor shall retain its rights under Section 2.1(a)(ii) and Section 2.4 as long as Enagas Investor has fully funded the lesser of (i) the Enagas Commitment or (ii) all amounts required to be funded pursuant to Section 5.4(c). In the event the BIP Funds offer Enagas Investor a Purchase Option and Enagas Investor elects not to participate in such Purchase Option or does not meet the Full Participation Condition, as applicable, Enagas Investor shall forfeit its rights under Section 2.1(a)(ii) until such time as Enagas Investor regains an Ownership Percentage equal to at least the Target Take-Private Ownership Percentage. The BIP Funds shall use good faith efforts to keep Enagas Investor reasonably informed of any intention to offer Enagas Investor the Purchase Option.

(e) The Acquiring Party may, in its reasonable discretion, impose such other reasonable and customary terms and procedures such as setting a closing date, rounding the number of Equity Interests covered by this Section 5.2 to the nearest whole Equity Interest and requiring customary closing deliveries in connection with any such transaction.

42

Section 5.3 TGE Investor Additional Investments.

(a) Secondary Purchases.

(i) On the date hereof, each TGE Investor has made cash contributions to Secondary Acquiror equal to their Ownership Percentage of the Secondary Purchase Amount for the purpose of making Secondary Purchases following the Effective Date. Aggregator GP, in its sole discretion, may cause Secondary Acquiror to make Secondary Purchases; provided, however, that no additional Class A Shares shall be purchased by Secondary Acquiror at a purchase price equal to the Specified Price or more per share without the consent of GIC Investor and Enagas Investor.

(ii) From and after the Effective Date and until the expiration of the Secondary Purchase Period, both (x) Agreed Purchases and (y) purchases of Class A Shares that are at a price per share equal to or exceeding the Specified Price and that are consented to by each TGE Investor shall only be consummated through Secondary Purchases made by Secondary Acquiror.

(iii) Any purchases of Class A Shares or any other equity securities of any member of the TGE Group by a BIP Fund or its Affiliates that are not either (x) made pursuant to either Section 5.3(a)(ii) or Section 5.3(b) or (y) Side Letter Purchases may not be effected through any Closing Silo Entity, but may be effected by any BIP Fund or its Affiliates through separate entities. For the avoidance of doubt, such separate entities shall not share in any of the economics of the Closing Silo Entities (subject to the provisions above with respect to Acceptable GP Transfers) unless otherwise agreed by all of the TGE Investors.

(iv) From and after the expiration of the Secondary Purchase Period, any TGE Investor may elect to cause Secondary Acquiror to distribute all remaining Secondary Purchase Amounts to the limited partners of Secondary Acquiror pursuant to the terms of the Secondary Acquiror LPA.

(b) Post-CFIUS Approval Enagas Investment. Promptly following the Enagas CFIUS Approval Date, Enagas Investor shall:

(i) purchase limited partner interests in each Aggregator Entity (for $83,373,052.26) and Secondary Acquiror (for $14,080,000.00), in each case, from each of the applicable BIP Funds that is a limited partner in each Aggregator Entity and Secondary Acquiror pro rata across each such Aggregator Entity and Secondary Acquiror, as applicable, in an aggregate amount sufficient to increase Enagas Investor’s Ownership Percentage by 3.52% such that Enagas Investor’s Ownership Percentage, immediately following such purchase, equals 28.42% (resulting in an expected aggregate purchase price of approximately $97.0 million (inclusive of Transaction Expenses) assuming no more than $400 million of post-closing Class A Share purchases are made after the Effective Date and prior to the time of the purchase); (“Enagas Post-CFIUS Investment Threshold Amount”); provided, that, in lieu of effecting the purchase of membership interests in VCOC Aggregator through a direct purchase from the members of VCOC Aggregator, such purchase shall be made by a contribution by Enagas Investor of the applicable amount in cash to ECI Aggregator, which ECI Acquiror shall use along with an assumption of the appropriate portion of the Debt Financing to purchase Class B Interests and membership interest in GP Acquiror from VCOC Acquiror (the “Post-CFIUS Approval Enagas Investment”).

(ii) The Post-CFIUS Approval Enagas Investment shall be made (i) with respect to each Aggregator Entity, on a look through basis at a price per Class B Share equal to the Post-CFIUS Approval Purchase Price plus a pro rata share of the Transaction Expenses and (ii) with respect to Secondary Acquiror, at a price per limited partner interest in Secondary Acquiror equal to the cost paid by the TGE Investors at Closing. The amount funded by Enagas Investor to fund the Post-CFIUS Approval Enagas

43

Investment is referred to as the “Additional Enagas Post-CFIUS Investment Amount.” Any amount of the Additional Enagas Post-CFIUS Investment Amount that is paid in order to increase Enagas Investor’s Ownership Percentage to the Enagas Post-CFIUS Investment Threshold Amount in respect of Class A Shares acquired after the Effective Date, including any purchase of limited partner interests in Secondary Acquiror, shall reduce the Enagas Commitment on a dollar for dollar basis.

(c) Enagas Commitment.

(i) In addition to the Secondary Purchases, each of the BIP Funds and Enagas Spain Investor agrees to make cash contributions in the applicable Additional Funding Amount (each, an “Additional Funding”), as requested by BIP from time to time (each, a “Capital Call”), to an entity designated and managed by BIP to fund the purchase of additional Class A Shares (which entity, for the avoidance of doubt, may not be a Closing Silo Entity unless the TGE Investors otherwise agree); provided, however, that no additional Class A Shares shall be purchased with the Enagas Commitment at a purchase price exceeding the Specified Price per share without the consent of Enagas Investor. In addition, to the extent that Enagas does not consent to the purchase of additional Class A Shares at a purchase price in excess of the Specified Price, and as a result, its Ownership Percentage or its ownership (on a look-through basis) of GP Acquiror is diluted, such dilution shall not be taken into account for purposes of the governance rights set forth herein. Each Additional Funding by Enagas shall reduce the Enagas Commitment on a dollar for dollar basis and in no event shall Enagas Investor be obligated at any time to make any Additional Funding in excess of its unpaid Enagas Commitment as of such time. Each Capital Call by BIP shall be made pursuant to a call notice (a “Call Notice”) setting forth (i) the amount of Additional Funding to be funded by Enagas in respect of such Capital Call, (ii) the account(s) and wire instructions to which such amounts should be paid and (iii) the date by which such amount is required to be funded (which shall not be less than 10 Business Days after the date such Call Notice is received by Enagas Spain Investor). Notwithstanding the foregoing, prior to the issuance of any Call Notice, BIP shall use its best efforts to keep Enagas Investor reasonably informed of its intention to make a Capital Call, to provide Enagas Investor with reasonable opportunity to be involved in such decision making process and to provide Enagas Investor with information relevant to the Capital Call as reasonably requested by Enagas Investor.

(ii) The BIP Funds shall use all of the Secondary Purchase Amount to purchase additional Class A Shares prior to making any additional Capital Calls.

(d) Enagas Default.

(i) If Enagas Investor fails to make the Post-CFIUS Approval Enagas Investment as prescribed in Section 5.3(b) or any Additional Funding required by a Capital Call as prescribed in Section 5.3(c) or if the BIP Funds fail to make any Additional Funding required by a Capital Call as prescribed in Section 5.3(c) (the amount that the Enagas Investor or the BIP Funds fail to fund, a “Defaulted Funding”) and, in the case of Enagas Investor, does not cure such failure within five Business Days after notice from BIP of such failure, Enagas Investor and the BIP Funds, as applicable, shall be deemed to be in “Co-Investment Default”. Enagas Investor and each Permitted Transferee to whom Enagas Investor has Transferred or proposes to Transfer Interests and the BIP Funds and each Permitted Transferee to whom the BIP Funds have Transferred or propose to Transfer Interests shall be deemed to be a “Co-Investment Defaulting Member”. A Co-Investment Defaulting Member shall: (i) be in default of this Agreement, but shall remain fully obligated to make any Defaulted Funding which such Co-Investment Defaulting Member failed to fund; and (ii) be subject to all such other rights and remedies as BIP, Enagas Investor and Aggregator GP, as applicable, may have against such Co-Investment Defaulting Member, including rights and remedies arising from such Co-Investment Defaulting Member’s breach of this Agreement. Furthermore, to the fullest extent permitted by applicable Law, BIP or Enagas Investor, as applicable, may, and Aggregator GP may cause the applicable entity to, take any one or more of the following remedial actions (to the extent not mutually exclusive with any other remedy described in this Section 5.3(d)) with respect to a Co-Investment Defaulting Member:

44

(A) loan the Co-Investment Defaulting Member an amount equal to such Co-Investment Defaulting Member’s Defaulted Funding and charge interest on such amount at a rate of the lesser of (1) 15% and (2) the maximum rate permitted under applicable Law;

(B) reduce the Enagas Commitment to zero ($0.00) such that Enagas Investor shall no longer have the right to participate in future acquisitions of Interests;

(C) charge interest on the Co-Investment Defaulting Member’s Defaulted Funding at the maximum rate permitted under applicable Law, or such other lower rate determined by BIP or Enagas Investor, as applicable; or

(D) pursue any other rights and remedies BIP, Enagas Investor or Aggregator GP, as applicable, may have against such Co-Investment Defaulting Member, including instituting suit for the Defaulted Funding, interest thereon, and reasonable costs and expenses, of enforcement of the Co-Investment Defaulting Member’s obligations.

(ii) Enagas Investor and the BIP Funds agree that the foregoing provisions of this Section 5.3(d) (including any abrogation of rights in respect of distributions or withdrawals, and any right of sale or forfeiture in respect of Interests pursuant to this Section 5.3(d)) are reasonable under the circumstances and constitute a good faith estimate of the loss likely to be suffered by BIP and the Closing Silo Entities in the event that Enagas Investor becomes a Co-Investment Defaulting Member or by Enagas Investor and the Closing Silo Entities in the event that any of the BIP Funds becomes a Co-Investment Defaulting Member.

(iii) Enagas Investor and the BIP Funds, as the case may be, shall be liable for the reasonable costs and expenses (including attorneys’ fees and expenses) incurred by BIP, Enagas Investor or any Closing Silo Entity, as applicable, in connection with the exercise of any of the remedies set forth in this Section 5.3(d) or arising out of any legal proceeding against such Co-Investment Defaulting Member relating to such Co-Investment Defaulting Member’s failure to comply with this Section 5.3(d).

ARTICLE VI

INDEMNIFICATION

Section 6.1 Right to Indemnification.

(a) Subject to the limitations and conditions as provided herein and to the fullest extent permitted by applicable Laws, each of the Closing Silo Entities (each, an “Indemnifying Party”) shall defend and indemnify each TGE Investor, Aggregator GP and their respective Affiliates, directors, officers, employees, managers, partners, controlling Persons, members and equityholders (collectively, “Indemnified Party”), in respect of, and hold them harmless from and against, any and all losses, damages, claims, costs, judgments, fines, settlements and expenses (including, without limitation, reasonable legal expenses and experts’ fees), but excluding any lost profits or punitive damages unless owed by an Indemnified Party to a third party, suffered, incurred or sustained by any Indemnified Party or to which such Indemnified Party becomes subject, however so arising whether under tort, contract, negligence, strict liability or otherwise, resulting from, arising out of, or relating to or in connection with any threatened, pending or completed third party 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 such Person, or a Person of

45

whom such Person is the legal representative is or was a partner (or Affiliate, director, officer, employees, manager, partner, controlling Person, member or equityholder thereof) of any Closing Silo Entity; provided, however, that no Person shall be entitled to indemnification under this Section 6.1 if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which such Indemnified Party is seeking indemnification pursuant to this Section 6.1 such Indemnified Party’s actions or omissions constituted bad faith, willful misconduct or criminal wrongdoing. The rights granted pursuant to this Article VI shall be deemed contract rights, and no amendment, modification or repeal of this Article VI 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 ACKNOWLEDGED THAT THE INDEMNIFICATION PROVIDED IN THIS ARTICLE VI COULD INVOLVE INDEMNIFICATION FOR NEGLIGENCE OR UNDER THEORIES OF STRICT LIABILITY.

(b) If the Indemnifying Parties are required to indemnify any Indemnified Party hereunder, such indemnification shall be allocated among the Indemnifying Parties such that each of (i) the Non-ECI Silo Entities, (ii) the ECI Silo Entities and (iii) the VCOC Silo Entities shall each bear a portion of such indemnification pro-rata based on their respective ownership of Class A Shares and Class B Interests. Any indemnification pursuant to this Article VI shall be made only out of the assets of the Closing Silo Entities, it being agreed that Aggregator GP shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to any Closing Silo Entity to enable it to effectuate such indemnification.

Section 6.2 Indemnification and Expense Advancement With Respect to Actions Commenced by an Indemnified Party. Notwithstanding Section 6.1 and Section 6.3, the Indemnifying Party shall be required to indemnify and advance expenses to an Indemnified Party in connection with any action, suit or proceeding commenced by such Indemnified Party unless (i) the commencement of such action, suit or proceeding by such Indemnified Party was authorized by Aggregator GP in case the Indemnified Party is a TGE Investor other than GP Aggregator or any BIP Fund and its Affiliates directors, officers, employees, managers, partners, controlling Persons, members and equityholders or (ii) the commencement of such action, suit or proceeding by such Indemnified Party was authorized by GIC Investor and Enagas Investor in case the Indemnified Party is GP Aggregator or any BIP Fund and its Affiliates directors, officers, employees, managers, partners, controlling Persons, members and equityholders.

Section 6.3 Advance Payment. Any right to indemnification conferred in this Article VI shall include a limited right to be paid or reimbursed by the Indemnifying Party for any and all reasonable expenses as they are incurred by a Person entitled or authorized to be indemnified under Section 6.1 who was, is 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 the final disposition of a Proceeding shall be made only upon delivery to the Indemnifying Party of a written affirmation by such Person of his good faith belief that he has met the requirements necessary for indemnification under this Article VI 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 VI or otherwise.

Section 6.4 Appearance as a Witness. Notwithstanding any other provision of this Article VI, the Indemnifying Party shall pay or reimburse expenses incurred by any Person entitled to be indemnified pursuant to this Article VI 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.

46

Section 6.5 Nonexclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in this Article VI shall not be exclusive of any other right which a Person indemnified pursuant to Section 6.1 may have or hereafter acquire under any Laws, this Agreement, or any other agreement, or otherwise.

Section 6.6 Savings Clause. If this Article VI or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Indemnifying Party shall nevertheless indemnify and hold harmless any Person entitled to be indemnified pursuant to this Article VI as to all losses, damages, claims, costs, judgments, fines, settlements and expenses (including, without limitation, reasonable legal expenses and experts’ fees) with respect to any Proceeding to the full extent permitted by any applicable portion of this Article VI that shall not have been invalidated and to the fullest extent permitted by Laws.

Section 6.7 Scope of Indemnity. For the purposes of this Article VI, references to the Indemnifying Party 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 VI shall stand in the same position under the provisions of this Article VI with respect to the resulting or surviving entity as he would have if such merger, consolidation, or other reorganization never occurred.

Section 6.8 Other Indemnities. To the maximum extent permitted by Law, as among (i) any member of the TGE Group, (ii) any Closing Silo Entity (in accordance with Section 6.1(a)) and (iii) any Other Indemnification Agreements, this Section 6.8 shall be interpreted to reflect an ordering of liability for potentially overlapping or duplicative indemnification payments, with (x) any member of the TGE Group having primary liability pursuant to any TGE Indemnification Rights, (y) any Closing Silo Entity (in accordance with Section 6.1(a)) having secondary liability and (z) the Other Indemnification Agreements having tertiary liability. If the applicable Indemnifying Party fails to indemnify or advance expenses to an Indemnified Party as required or contemplated by this Agreement, and any Person makes any payment to such Indemnified Party in respect of indemnification or advancement of expenses under any Other Indemnification Agreement on account of such Unpaid Indemnity Amounts, such other Person shall be subrogated to the rights of such Indemnified Party under this Agreement in respect of such Unpaid Indemnity Amounts. The parties hereto irrevocably waive, relinquish and release any Person party to any Other Indemnification Agreement with an Indemnified Party from any and all claims for contribution, subrogation or any other recovery of any kind in respect of any of the matters described in this Article VI for which any Indemnified Party has received indemnification or advancement.

Section 6.9 Liability of Indemnified Party.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnified Party shall be liable for monetary damages to the Indemnifying Party or any other Person who is bound by this Agreement, for losses sustained or liabilities incurred as a result of any act or omission of an Indemnified Party unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnified Party’s actions constituted bad faith, willful misconduct or criminal wrongdoing.

(b) To the extent that, at law or in equity, an Indemnified Party has duties and liabilities relating thereto to a Closing Silo Entity, the partners thereof, or any other Person who is bound by this Agreement, any Indemnified Party acting in connection with the such Closing Silo Entity’s business or affairs shall not be liable, to the fullest extent permitted by Law, to such Closing Silo Entity, to any partner thereof, or to any other Person who is bound by this Agreement for its reliance on the provisions of this Agreement and the other governing documents of such Closing Silo Entity.

47

(c) Any amendment, modification or repeal of this Agreement or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnified Party under this Agreement as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.5 Remedies; Specific Performance. Each Party acknowledges and agrees that an award of monetary damages for failure to comply with this Agreement may not be an adequate remedy for the Party attempting to enforce such provisions and the non-breaching Party may have no adequate remedy at law. Accordingly, each Party agrees that the non-breaching Party will have the right, in addition to any other rights and remedies available at law or in equity, to enforce its rights and each other Party’s obligations under this Agreement by an action or actions for specific performance and injunctive or other equitable relief as a remedy for any such breach or threatened breach, without the requirement of posting bond or other security. The non-breaching Party shall be entitled to recover its costs and expenses, including attorneys’ fees, incurred in connection with any successful action brought by it to enforce the breaching Party’s obligations to comply with such provisions.

Section 7.6 Entire Agreement. This Agreement, together with the other Transaction Documents, constitutes the entire agreement of the Parties with respect to the subject matter hereof and there are no agreements, understandings, representations or warranties between the Parties other than those set forth or referred to herein or therein. Each TGE Investor has made, in consultation with its legal, financial and tax advisors, its own independent inquiry and investigation into, and based thereon has formed an independent judgment concerning, the transactions contemplated by this Agreement and the other Transaction Documents.

Section 7.7 Third-Party Beneficiaries. This Agreement is made solely and specifically between and for the benefit of the Parties hereto and their respective successors and assigns. Nothing in this Agreement is intended or shall be construed to confer upon or give any Person other than the parties hereto, any rights or remedies under or by reason of this Agreement, or result in their being deemed a third-party beneficiary of this Agreement.

Section 7.9 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, however, that no Party hereto shall assign its rights or delegate any or all of its obligations under this Agreement, except (i) as expressly provided in Section 4.2 hereof and (ii) in connection with any Permitted Transfer pursuant to clause (i) of the definition of Permitted Transfer.

Section 7.10 Amendments. All amendments to this Agreement must be in writing and signed by all Parties; provided that, Aggregator GP may amend this Agreement, without the consent of any other Party hereto, solely, to the extent permitted by Section 7.17 hereof, in order to (i) provide any Additional Investor with (a) board or committee director designation or observer rights (including in respect of any Subsidiary) of the type granted to the Co-Investors in Section 2.1, but only to the extent that such rights or the grant of such rights do not result in an increase in the size of the Board without GIC Investor’s consent as provided in Section 2.1(f) and do not infringe or limit the rights of the GIC Investor with respect to such matters (b) consent rights, including those granted to the Co-Investors in Sections 2.3 and 2.4, with respect solely to entities in which such Additional Investor is directly or indirectly invested and solely to the extent that such rights or the grant of such rights does not adversely impact, limit or infringe the rights or obligations of any other Co-Investor prior to such amendment or otherwise disproportionately adversely affect a Co-Investor as compared to the BIP Funds, (c) cooperation rights in respect of securities filings granted to the Co-Investors in Section 2.7, (d) information rights with respect to entities in which such Additional Investor is directly or indirectly invested, including those granted to the Co-Investors in Sections 3.1 through 3.3, (e) rights to make Permitted Transfers as contemplated by Section 4.1, (f) tag-along rights granted to the Co-Investors in Section 4.5, (g) registration rights granted to the Co-Investors in Section 4.6; (h) pre-emptive rights granted to the Co-Investors in Section 5.1, (i) indemnification rights consistent with Article VI but only to the extent that all the entities in which such Additional Investor is invested are similarly joined as parties to this Agreement and included as Indemnifying Parties, and (j) any other rights derivative of the BIP Funds’ rights herein that are enforceable solely against the BIP Funds and that could be provided by the BIP Funds to an Additional Investor in a separate agreement to which neither Co-Investor is a party without resulting in a breach of this Agreement; and (ii) burden such Additional Investor with the drag-along obligations by which the Co-Investors are burdened in Section 4.4; provided, further, that, Aggregator GP shall give each other TGE Investor with as much notice of the intent to make such amendment and the general substance thereof as reasonably practicable in the circumstances (but not less than five (5) Business Days), and an opportunity (of not less than two (2) Business Days) to review and comment on the content of any amendments proposed to be made by Aggregator GP pursuant to the preceding proviso.

Section 7.11 Waivers. Any Party may, only by an instrument in writing, waive compliance by another Party with any term or provision of this Agreement. The waiver by any Party of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach. Except as otherwise expressly provided herein, no failure to exercise, delay in exercising or single or partial exercise of any right, power or remedy by any Party, and no course of dealing between the Parties, shall constitute a waiver of any such right, power or remedy.

Section 7.12 Severability. If any provision of this Agreement shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions of this Agreement shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

Section 7.13 Interpretation. In the event an ambiguity or question of intent or interpretation arises with respect to this Agreement, this Agreement shall be construed as if it were drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

Section 7.14 Further Assurances. The Parties agree that, from time to time, each of them will execute and deliver, or cause to be executed and delivered, such further agreements and instruments and take such other action as may be necessary to effectuate the provisions, purposes and intents of this Agreement; provided, however, that nothing in this Agreement shall require GIC Investor or Enagas Investor to provide non-public information with respect to itself or its Affiliates.

51

Section 7.15 Limited Recourse. Notwithstanding anything that may be expressed or implied in this Agreement, or any document or instrument delivered in connection herewith, by its acceptance of the benefits of this Agreement, the Parties covenant, agree and acknowledge that no Person other than the Parties hereto has any liabilities, obligations or commitments of any nature (whether known or unknown, whether due or to become due, absolute, contingent or otherwise) hereunder (in each case subject to the limitations provided herein) or in connection with the transactions contemplated hereby and that, notwithstanding that each Party or its general partner (and any assignee permitted under Section 7.9 hereof) may be a limited partnership, limited liability company or any other entity, no Party has any right of recovery under this Agreement or under any document or instrument delivered in connection herewith, against, or any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, this Agreement, the transactions contemplated hereby or in respect of any oral representation made or alleged to be made in connection herewith, against, and no personal liability whatsoever shall attach to, be imposed upon or otherwise be incurred by the former, current or future direct or indirect equity holders, controlling Persons, directors, officers, employees, agents, Affiliates (other than any assignee permitted under Section 7.9 hereof), members, managers or general or limited partners of any of the Parties or any former, current or future stockholder, controlling Person, director, officer, employee, general or limited partner, member, manager, Affiliate (other than any assignee permitted under Section 7.9 hereof) or agent of any of the foregoing, whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or applicable Law, or otherwise.

Section 7.16 No Corporate Opportunities Doctrine. Each Party acknowledges and agrees that (i) each of TGE Investor and its Affiliates manage investments in the energy industry in the ordinary course of business (such investments, “Institutional Investments”) and that each TGE Investor and its Affiliates may make Institutional Investments, even if such Institutional Investments are competitive with the business of the TGE Group, and (ii) each TGE Investor, its Affiliates and each of their Representatives, as applicable, (A) shall not be prohibited, by virtue of its status as a general partner, limited partner, director, designee, observer or otherwise from pursuing or engaging in such Institutional Investments; (B) shall not be obliged or have a duty to inform, or present to, any other Party or any member of the TGE Group of any opportunity, relationship or investment (and no other Party or any of its Affiliates will acquire or be entitled to any interest or participation in any such opportunity, relationship or investment) and shall not be bound by the doctrine of corporate opportunity (or analogous doctrine); and (C) shall not be deemed to have a conflict of interest with, or to have breached this Agreement or any duty (if any), whether express or implied by law, to, any other Party, any of its Affiliates or any member of the TGE Group by reason of such Person’s (or any of its representative’s or equity holder’s) involvement in such activities or interests.

Section 7.17 Additional Investors.

(a) None of the GP Acquiror, any member of the TGE Group, the BIP Funds or any of their respective Affiliates shall enter into any additional, or modify any existing, agreements with any Additional Investor that acquires a number of Interests less than or equal to the then-current Interests held by GIC Investor (in each case, on a look-through basis) from its capital invested as of the Effective Date and without giving effect to any incremental purchases of Class A Shares of TGE or Equity Interests in GP Acquiror by GIC Investor following the Closing, that have the effect of establishing governance (including approval rights), information or liquidity rights more favorable to such Additional Investor than such rights established in favor of GIC Investor by this Agreement.

(b) Other than those governance (including approval rights), information or liquidity rights given to GIC Investor as of the Effective Date, which may be established in respect of any Additional Investor subject only to the provisions of Section 7.17(a), none of the GP Acquiror, any member of the TGE Group, the BIP Funds or any of their respective Affiliates shall enter into any additional, or modify

52

any existing, agreements with any Additional Investor that acquires a number of Interests less than or equal to the then-current Interests held by Enagas Investor (in each case, on a look-through basis) from its capital invested as of the Effective Date and without giving effect to any incremental purchases of Class A Shares of TGE or Equity Interests in GP Acquiror by Enagas Investor following the Closing, that have the effect of (i) establishing information or liquidity rights more favorable to such Additional Investor (excluding, for this purpose limited partners or other investors in the BIP Funds or its Affiliates with respect to their information or liquidity rights with respect to their investment in the BIP Fund or its Affiliate generally) than such rights established in favor of Enagas Investor by this Agreement or (ii) with respect to any Additional Investor (excluding, for this purpose, limited partners or other investors in the BIP Funds or its Affiliates) governance rights (including approval rights) more favorable to such Additional Investor than such rights established in favor of Enagas Investor by this Agreement, in the case of each of the foregoing (i) and (ii), unless such rights are also offered to Enagas Investor. For the avoidance of doubt, the Enagas Investor consents to the rights given to GIC Investor pursuant to this Agreement as of the Effective Date.

Section 7.18 Expenses. The TGE Acquirors shall, at the Closing, pay for (or reimburse the applicable Co-Investor or its Affiliates to the extent paid prior to Closing) all reasonable and documented out of pocket costs and expenses incurred by each of the Co-Investors, BIP and their respective Affiliates in connection with the Transaction, including, without limitation, third-party financing fees, reasonable and documented travel expenses and other out-of-pocket costs and expenses, and fees and expenses of financial, legal, accounting, tax and other advisors and consultants on a pro-rata basis based on the TGE Acquirors’ respective proportional ownership of the Subject Interests; provided that, with respect to Enagas Investor, such payment or reimbursement shall only be made with respect to any such costs and expenses incurred since January 30, 2019; provided, further, that this Section 7.18 supersedes all other agreements between the TGE Investors with respect to fees and expenses.
