TAX MATTERS

Section 5.1 Intended Tax Treatment. For U.S. federal (and where applicable, state and local) income Tax purposes, the Parties intend to treat the contribution of the Contributed Interests by the Contributor to the Contributee as qualifying for nonrecognition of gain or loss pursuant to Section 721 of the Code, except to the extent otherwise required by Section 707 of the Code with respect to any actual or deemed transfer of money or other consideration from Contributee to Contributor in connection with the contribution of the Contributed Interests (the “Intended Tax Treatment”). Neither Party shall take any position inconsistent with the Intended Tax Treatment for any applicable Tax purpose unless required by a “determination” within the meaning of Section 1313 of the Code (or any analogous provision of applicable state, local or non-U.S. Tax Law).

Section 5.2 Maintenance of Books and Records.

(a) Until the earlier of the date that is (i) seven (7) years from the date of the Closing Date and (ii) six (6) months following the expiration of the applicable statute of limitations (including periods of waiver) for any Tax Returns filed or required to be filed by the Company covering the periods, or portions thereof, ending on or before the Closing Date, the Contributee shall retain all Tax Records of the Company that are in its possession. For this purpose, “Tax Records” means any Tax Return of the Company, workpapers related to such Tax Returns and documentation relating to any audit of any such Tax Returns, and any other books of account or records related to Taxes of the Company required or advisable to be maintained under Law.

(b) After the Closing Date, the Contributee shall (i) preserve and keep a copy of all Records in accordance with the records retention policy of the Contributee and its Affiliates (but, in the case of Tax Records, the Contributee shall preserve for at least the period specified in Section 5.2(a)); and (ii) upon reasonable notice and at the Contributor’s cost and expense, provide the Contributor, its Affiliates and their respective Representatives with reasonable access to, during normal business hours and in a manner that does not unreasonably interfere with normal business operations of the Contributee or the Company, the Records (to the extent that the Contributor has not retained the original or a copy) for review and copying in connection with any Proceeding involving the Company (excluding any Proceeding where the Parties are adverse to one another) or for any other reasonable purpose. Before the Contributee disposes, or causes the Company to dispose, of any such Records, the Contributee shall give the Contributor at least ninety (90) days’ prior notice to such effect, and the Contributor shall be given an opportunity, at its cost and expense, to remove and retain all or any part of such Records as the Contributor may select.

Section 5.3 Cooperation on Tax Returns and Proceedings.

(a) Cooperation Generally. The Contributee and the Contributor shall cooperate fully as and to the extent reasonably requested by a Party in connection with the filing of Tax Returns and any audit, examination or other administrative or judicial proceeding with respect to Taxes imposed on or with respect to the assets, operations or activities of the Company. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax proceeding and making employees available on a mutually convenient basis, acting reasonably, to provide additional information and explanation of any material provided hereunder.

9

(b) Tax Returns. The Contributee shall cause each Pre-Closing Tax Return and Straddle Period Tax Return required to be filed after the Closing Date to be timely executed and filed. The Contributee shall prepare all such Pre-Closing Tax Returns or Straddle Period Tax Returns that are Flow-Through Tax Returns in accordance with past practice, shall provide drafts of such Flow-Through Tax Returns to Contributor for its review and comment at least fifteen (15) Business Days before the relevant filing deadline (taking into account any properly obtained extensions), and shall consider in good faith all reasonable comments to any such Flow-Through Tax Return received in writing no later than ten (10) calendar days after the date such Flow-Through Tax Return is delivered to Contributor. Neither Party may amend, refile or otherwise modify, or cause or permit to be amended, refiled or otherwise modified, any Flow-Through Tax Return filed with respect to the Company for any Pre-Closing Tax Period or any Straddle Period without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(c) Tax Audits. If any Taxing Authority issues to the Company or the Contributee a notice of its intent to audit or conduct another legal or administrative proceeding with respect to a Pre-Closing Tax Returns or Straddle Period Tax Returns of the Company or any member of the Company Group that are Flow-Through Tax Returns, the Contributee shall promptly notify the Contributor. The Contributee shall be entitled, at its sole cost and expense, to control the defense of any such proceeding, but (i) the Contributee shall keep the Contributor reasonably informed of the progress of such proceeding, (ii) the Contributor shall have the right, at its own expense, to participate with Representatives of its choosing in all stages of such proceeding, (iii) the Contributee shall, in instances where an action would have a disproportionate impact on Contributor, consult in good faith with the Contributor before taking any material action with respect to the conduct of such proceeding, offer the Contributor an opportunity to comment before submitting any material written materials prepared or furnished in connection with such proceeding and consider in good faith any reasonable comments provided by the Contributor and (iv) in the case of any material proceeding, the Contributee shall not settle such proceeding without the prior written consent of the Contributor, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 5.4 Section 706 Matters. Notwithstanding anything to the contrary in this Agreement, the Contributee shall cause the Company, and, to the extent reasonably practicable, each partnership in which the Company is a partner, for U.S. federal income tax purposes to allocate all items of income, gain, loss, deduction or credit for the tax year in which the Closing Date occurs in accordance with the interim closing of the partnership books method described in Treasury Regulations Section 1.706-1(c)(2)(ii).

Section 5.5 Waiver of Tax Termination. The Parties hereby waive the application of Section 3.03(c) of the Company LLC Agreement to the contribution of the Contributed Interests and any other transactions contemplated by this Agreement.

10

Section 5.6 Push Out Election. Notwithstanding anything to the contrary in this Agreement, from and after the date of this Agreement, in the event that a Tax proceeding involving the Company and relating to a Tax period that either includes or ends prior to the Closing Date results in an “imputed underpayment” under Section 6225 of the Code (or analogous provision of state or local Tax Law) imposed on the Company, to the extent requested by either Party, the other Party shall cooperate with the first Party to make a “push out” election under Section 6226(a) of the Code (and any analogous election under state or local Tax Law, if applicable) with respect to such “imputed underpayment”; provided, however, that if the Partnership Representative (as defined in the Company LLC Agreement) determines in good faith that such election is administratively impractical or uneconomical, then the Company may treat such imputed underpayment as a Company expense. If the Company fails to make a “push out” election under Section 6226(a) of the Code (and any analogous election under state or local Tax Law, if applicable) with respect to such “imputed underpayment,” the Contributee shall use commercially reasonable efforts to (a) take into account the Contributor’s tax status (and the tax status of Contributor’s beneficial owners) to reduce any proposed “imputed underpayment” and (b) ensure that the Contributor does not bear economically the cost of any Taxes that are imposed as a result of the Tax status of the Contributee and its beneficial owners.

Section 5.7 Transfer Taxes. All transfer, documentary, sales, use, value added, goods and services, stamp, registration, notarial fees and other similar Taxes and fees (collectively, “Transfer Taxes”), if any, arising from the consummation of the contemplated transaction hereunder shall be borne equally by the Contributor, on the one hand, and the Contributee, on the other hand. The Contributor and the Contributee shall cooperate and join in the execution and filing of any applicable Tax Returns and other documentation in connection with such Transfer Taxes.

Section 5.8 Withholding. Contributee shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code, or any provision of state, local or non-U.S. Tax Law. If Contributee determines that any deduction or withholding (other than in respect of employment compensation or as a result of the failure to comply with Section 1.3(b)(iii)) is required in respect of a payment pursuant to this Agreement, Contributee shall promptly provide notice to Contributor after making such determination, but in any event at least five (5) Business Days prior to the time at which such payment is to be made, with a written explanation substantiating the requirement to so withhold and shall cooperate in good faith with Contributor to eliminate or reduce any such withholding or deduction to the extent permitted by Law; provided, that unless required by a change in Law after the date hereof, no amounts will be withheld under Section 1445 or Section 1446(f) of the Code from any payments or consideration in respect of the Contributed Interests to the extent the documentation described in Section 1.3(b)(iii) is delivered on or prior to the Closing Date. Contributee shall promptly remit all withheld amounts to the applicable Taxing Authority in accordance with applicable Law. Any amounts that are so deducted and withheld shall be treated for all purposes of this Agreement as having been paid to the Persons who would have received such amounts had no deduction and withholding been required.

Section 6.4 Certain Indemnification Matters.

(a) Contributee agrees that, during the period that commences on the Closing Date and ends on the sixth (6th) anniversary of the Closing Date, it shall maintain, or cause the Company to maintain, in full force and effect and shall not cause any amendment, modification, waiver or termination to the Organizational Documents of the Company Group or Contributee as such documents exist on the date of this Agreement, the effect of which would be to affect adversely the indemnification or similar rights of any person serving as a member of the board of managers or officer of any member of the Company Group or Contributee as of the date of this Agreement; provided, however, that the foregoing restriction shall not apply to any such amendment, modification, waiver, or termination to the extent required to cause such provisions (or any portion thereof) to comply with applicable Law.

(b) Contributee agrees that, during the period that commences upon the consummation of the transactions contemplated by this Agreement and ends on the sixth (6th) anniversary of the Closing Date, with respect to each individual who served as a director or manager of a member of the Company Group at any time prior to the Closing Date (the “Covered Directors”), Contributee shall cause the Company or the applicable member of the Company Group (i) to continue in effect the current director and officer liability or similar insurance policy or policies that such member of the Company Group has as of the date of this Agreement, or (ii) upon the termination or cancellation of any such policy or policies, (x) to provide director and officer liability or similar insurance in substitution for, or in replacement of, such cancelled or terminated policy or policies or (y) to provide a “tail” or runoff policy (covering all claims, whether choate or inchoate, made during such six (6) year period) (the costs of which shall not exceed 300% of the annual aggregate premium for the current such coverage maintained by the Company Group as of the date of this Agreement, in each case so that each Covered Director has coverage thereunder for acts, events, occurrences, or omissions occurring or arising at or prior to the Closing to the same extent (including policy limits, exclusions, and scope); provided, that if the cost for such tail policy exceeds such amount, Contributee shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount) as such Covered Director has coverage for such acts, events, occurrences, or omissions under the director and officer insurance or similar policy maintained by any of member of the Company Group as of the date of this Agreement.

(c) Contributee hereby acknowledges that certain Covered Directors may have rights to indemnification, advancement of expenses, and/or insurance provided by persons other than the Company Group (collectively, the “Indemnitors”). With respect to claims, liabilities, and expenses for which any member of the Company Group may be obligated to indemnify, advance expenses to, or insure any of the Covered Directors:

(i) (A) the applicable member of the Company Group is the indemnitor of first resort (i.e., its obligations to the Covered Directors are primary and any obligation of the Indemnitors are secondary), and (B) the applicable member of the Company Group or Contributee shall be required to (and Contributee shall cause the members of the Company Group to) advance the full amount of expenses incurred by any Covered Director and shall be liable for the full amount of all expenses, judgments, penalties, fines, and amounts paid in settlement to the extent (x) legally permitted and (y) required by the terms of this Agreement or the Organizational Documents of the applicable member of the Company Group, without regard to any rights the Covered Director may have against the Indemnitors;

13

(ii) Contributee and the Company Group irrevocably waive, relinquish, and release the Indemnitors from any and all claims against the Indemnitors for contribution, subrogation, or any other recovery of any kind in respect thereof;

(iii) no advancement or payment by an Indemnitor on behalf of a Covered Director with respect to any claim for which a Covered Director has sought indemnification from a member of the Company Group or Contributee shall affect the foregoing, and the applicable Indemnitor shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of the Covered Director against the Company Group or Contributee; and

(iv) the Indemnitors are express third-party beneficiaries of the terms of this Section 6.4(c).

(d) In the event that any member of the Company Group or Contributee or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) in one or more series of transactions, directly or indirectly, transfers all or substantially all of its properties and assets to any Person (whether by consolidation, merger, or otherwise), then, and in each such case, proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets or its respective successors and assigns, as the case may be, assume the obligations set forth in this Section 6.4.

(e) The obligations of Contributee under this Section 6.4 shall not be terminated or modified in such a manner as to adversely affect any Covered Director to whom this Section 6.4 applies without the consent of the affected Covered Director. The provisions of this Section 6.4 are intended to be for the benefit of, and shall be enforceable by, each of the Covered Directors and such Covered Director’s heirs and personal Representatives.

Section 6.5 Company Distribution. Notwithstanding anything in this Agreement to the contrary, to the extent not paid at or prior to the Closing, promptly following the Closing and in any event no later than such date on which quarterly distributions have been made by the Company in the ordinary course in prior years, Contributee shall cause to be paid to Contributor an amount in cash, payable via wire transfer in immediately available funds, equal to the quarterly distribution payment attributable to Contributor’s proportionate ownership interest in the Company pursuant to Section 5.01(a) of the Company LLC Agreement, in each case for the period beginning on April 1, 2022 and ending on the earlier to occur of (A) the Closing Date and (B) June 30, 2022.

ARTICLE 9

SURVIVAL; REMEDIES

Section 9.1 Indemnification.

(a) From and after the Closing, the Contributee shall indemnify, defend and hold harmless the Contributor Group from and against all Damages incurred or suffered by the Contributor Group or any member thereof (whether such Damages relate to a Third Person Claim or a direct claim by a member of the Contributor Group) and caused by or arising out of:

(i) the Contributee’s breach of any of its covenants or agreements contained in this Agreement; and

(ii) the Contributee’s breach of any representation or warranty of the Contributee contained in Article 3 or in the respective certificate delivered by the Contributee on the Closing Date pursuant to Section 7.2(c).

(b) From and after the Closing, the Contributor shall indemnify, defend and hold harmless the Contributee Group from and against all Damages incurred or suffered by the Contributee Group or any member thereof (whether such Damages relate to a Third Person Claim or a direct claim by a member of the Contributee Group) and caused by or arising out of:

(i) the Contributor’s breach of any of the Contributor’s covenants or agreements contained in this Agreement; and

(ii) the Contributor’s breach of any representation or warranty of the Contributor contained in Article 2 or in the certificate delivered by the Contributor on the Closing Date pursuant to Section 7.1(c).

(c) The indemnity of each Party provided in this Section 9.1 shall be for the benefit of and extend to each Person included in the Contributor Group and the Contributee Group, as applicable; provided, however, that any claim for indemnity under this Section 9.1 by any such Person must be brought and administered by a Party. No Indemnified Person (including any member of the Contributor Group or the Contributee Group) other than the Contributor and the Contributee shall have any rights against the Contributee or the Contributor, as applicable, under the terms of this Section 9.1 except as may be exercised on its behalf by the Contributee or the Contributor, as applicable, pursuant to this Section 9.1(c). Each Party may elect to exercise or not exercise indemnification rights under this Article 9 on behalf of the other Indemnified Persons Affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Article 9.

17

Section 9.2 Indemnification Actions. All claims for indemnification under Section 9.1 shall be asserted and resolved as follows:

(a) For purposes hereof, (i) the term “Indemnifying Person” when used in connection with particular Damages shall mean the Party charged with an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 9 and (ii) the term “Indemnified Person” when used in connection with particular Damages shall mean the Person or Persons having the right to be indemnified with respect to such Damages by a Party pursuant to this Article 9.

(b) To make a claim for indemnification under Section 9.1, an Indemnified Person shall notify the Indemnifying Person of its claim under this Section 9.2, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a third Person against the Indemnified Person (a “Third Person Claim”), the Indemnified Person shall provide its Claim Notice promptly (but in any event within ten (10) Business Days) after the Indemnified Person has actual knowledge of the Third Person Claim and shall enclose a copy of all papers (if any) served with respect to the Third Person Claim; provided that the failure of any Indemnified Person to give notice of a Third Person Claim as provided in this Section 9.2 shall not relieve the Indemnifying Person of its obligations under Section 9.1 except to the extent such failure materially prejudices the Indemnifying Person’s ability to successfully defend against the Third Person Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement set forth in this Agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement which was inaccurate or breached along with a description of such breach in reasonable detail.

(c) In the case of a claim for indemnification based upon a Third Person Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it elects to control the defense of such Third Person Claim under this Article 9 (such election to be without prejudice to the right of the Indemnifying Person to dispute whether such Third Person Claim is for indemnifiable Damages under this Article 9). If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period whether the Indemnifying Person elects to control the defense of such Third Person Claim, it shall be conclusively deemed to not undertake such defense of such Third Person Claim. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person elects to control the defense of such Third Person Claim or does timely elect to control such defense, it shall have the right, but not the obligation, to defend, at its sole cost and expense, the Third Person Claim and the Indemnified Person shall not be entitled to reimbursement of any reasonable costs or expenses incurred with respect to such Third Person Claim prior to the date thereof. The Indemnifying Person shall have full control of such defense and proceedings, including, subject to the last sentence of this

18

Section 9.2(d), any compromise or settlement thereof. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Third Person Claim which the Indemnifying Person elects to contest. The Indemnified Person may, at its own expense, participate in, but not control, any defense or settlement of any Third Person Claim controlled by the Indemnifying Person pursuant to this Section 9.2(d). An Indemnifying Person shall not, without the prior written consent of the Indemnified Person, settle any Third Person Claim or consent to the entry of any judgment with respect thereto which (i) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Person Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person), (ii) obligates the Indemnified Person to make any payment that is not made by the Indemnifying Person, (iii) is reasonably expected to materially and adversely affect the Indemnified Person or (iv) admits to wrongdoing or culpability on the part of the Indemnified Person.

(e) If the Indemnifying Person does not timely elect to control the defense of such Third Person Claim but fails to diligently defend or settle the Third Person Claim, then the Indemnified Person shall have the right to defend against the Third Person Claim (at the sole cost and expense of the Indemnifying Person (but subject to the limitations set forth in this Article 9), if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to admit its obligation and assume the defense of the Third Person Claim at any time prior to settlement or final determination thereof. If the Indemnifying Person has not yet elected to control the defense of such Third Person Claim, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) Business Days following receipt of such notice to (i) admit in writing its obligation to provide indemnification with respect to the Third Person Claim (subject to the limitations set forth in this Article 9) and (ii) if its obligation is so admitted, reject, in its reasonable judgment, the proposed settlement. If the Indemnified Person settles any Third Person Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely assumed the defense of a Third Person Claim and diligently defended thereafter, the Indemnified Person shall be conclusively deemed to have waived any right to indemnity therefor.

(f) In the case of a claim for indemnification not based upon a Third Person Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages (subject to the limitations set forth in this Article 9) or (iii) dispute the claim for such indemnification. If the Indemnifying Person does not notify the Indemnified Person within such 30-day period that it has cured the Damages or that it disputes the claim for such indemnification, the Indemnifying Person shall be conclusively deemed to have denied such indemnification obligation hereunder.

Section 9.3 Limitation on Actions.

(a) The representations and warranties of the Parties in this Agreement, the representations and warranties given in the certificates delivered at the Closing pursuant to Section 7.1(c) and Section 7.2(c), as applicable, and the covenants and agreements of the Parties in this Agreement that are to be performed at or prior to Closing shall survive the Closing until the first (1^st) anniversary of the Closing Date. The covenants and agreements contained in this

19

Agreement that are to be performed after Closing (unless fully performed prior to or at the Closing) shall survive the Closing in accordance with the respective terms thereof. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to, and in accordance with the terms of, this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Section 9.1(a) and Section 9.1(b) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification thereunder (and no claims shall be permitted to be made thereunder), except in each case as to matters for which a bona fide Claim Notice for indemnity has been delivered in good faith to the Indemnifying Person on or before such termination date.

(c) Notwithstanding anything to the contrary contained elsewhere in this Agreement, from and after the Closing:

(i) except in the case of fraud, from and after the Closing, the sole and exclusive remedies of a Party against the other Party for any Damages arising from a breach of this Agreement shall be the rights and remedies provided by or set forth in Section 9.1(a), Section 9.1(b) and Section 10.14; and

(ii) (A) the Contributor shall not be required to indemnify the Contributee under this Article 9 for aggregate Damages in excess of $245,000,000 and (B) the Contributee shall not be required to indemnify the Contributor under this Article 9 for aggregate Damages in excess of the Closing Consideration.

(d) The amount of any Damages for which any Indemnified Person is entitled to indemnification under this Article 9 shall be reduced (or if applicable, shall be refunded promptly by the Indemnified Person if previously paid to the Indemnified Person by or on behalf of the Indemnifying Person) to the extent of (i) the amount of insurance proceeds received by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs), and (ii) the amount recovered by an Indemnified Person or its Affiliates pursuant to any indemnification agreement with any Third Party.

(e) In no event shall any Indemnified Person be entitled to duplicate compensation with respect to the same Damage under more than one provision of this Agreement and the various documents delivered in connection with the Closing.

(f) Any indemnity payment under this Agreement shall be treated as an adjustment to the Closing Consideration for Tax purposes, unless otherwise required by applicable Law.

(g) Any indemnity payment under this Agreement owed by Contributee to Contributor under this Article 9 is, at the sole discretion of the Contributee, payable (i) in cash or (ii) by transferring Common Units representing the amount owed based on a value per Common Unit of the greater of (A) the Common Unit Price and (B) the closing price of a Common Unit on the last trading day before the payment of such amount owed by Contributee to Contributor under this Article 9.

20

Section 9.4 Release. Effective as of the Closing, (a) Contributee hereby, on its own behalf and on behalf of its Affiliates (including the Contributee Group), unconditionally and irrevocably releases and waives any claims that Contributee or such Affiliates (including the Contributee Group) have or may have against Contributor or any member of the Contributor Group in its capacity as an equity owner of Contributor and arising out of, resulting from, or relating to actions, omissions, facts, or circumstances occurring, arising, or existing at or prior to the Closing; and (b) Contributor hereby, on its own behalf and on behalf of its Affiliates (including the Contributor Group), unconditionally and irrevocably releases and waives any claims that Contributor or such Affiliates (including the Contributor Group) have or may have against Contributee, the Company or any member of the Contributee Group arising out of, resulting from, or relating to actions, omissions, facts, or circumstances occurring, arising, or existing at or prior to the Closing; provided, that notwithstanding the foregoing, nothing contained in this Section 9.2 is intended to, nor does it, extend to any claims in respect of this Agreement or any of the provisions set forth herein.

Section 10.12 Conspicuous. THE PARTIES AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE OR ENFORCEABLE, THE PROVISIONS IN THIS AGREEMENT IN BOLD-TYPE FONT ARE “CONSPICUOUS” FOR THE PURPOSE OF ANY APPLICABLE LAW.

Section 10.13 Time of Essence. This Agreement contains a number of dates and times by which performance or the exercise of rights is due, and the Parties intend that each and every such date and time be the firm and final date and time, as agreed. For this reason, each Party hereby waives and relinquishes any right it might otherwise have to challenge its failure to meet any performance or rights election date applicable to it on the basis that its late action constitutes substantial performance, to require the other Party to show prejudice, or on any equitable grounds. Without limiting the foregoing, time is of the essence in this Agreement.

Section 10.15 Schedules. The inclusion of a matter on a Schedule to this Agreement in relation to a representation or warranty shall not be deemed an indication that such matter necessarily would, or may, breach such representation or warranty absent its inclusion on such Schedule. Any item or matter disclosed on any Schedule to this Agreement shall be deemed to have been disclosed for purposes of all representations and warranties under this Agreement, without the need for specific references on each Schedule or cross-references thereto, so long as the relevance for such disclosure is reasonably apparent on its face. Matters may be disclosed on a Schedule for information purposes only.

Section 10.16 Severability. The invalidity or unenforceability of any term or provision of this Agreement in any situation or jurisdiction shall not affect the validity or enforceability of the other terms or provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction and the remaining terms and provisions shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement which is manifestly unjust.

ARTICLE II

RIGHT OF FIRST OFFER

Section 2.01 Offering Notice. At all times prior to [•], 2024¹, if First Reserve or any of its Affiliates desires to sell all or any part of its Issued Units (other than in connection with exercising its Piggyback Rights under Section 3.03), First Reserve or its applicable Affiliate (a “ROFO Seller”) shall first grant to Crestwood a right, but not an obligation (except as otherwise set forth in this Section 2.01), pursuant to the terms of this Section 2.01, to purchase all of the Common Units that the ROFO Seller desires to sell by sending written notice (an “Offering Notice”) to Crestwood, which shall state (i) the number of Common Units such ROFO Seller intends to sell (the “Subject Units”), (ii) the intended date of pricing such sale (which shall be not less than five days from the date of receipt of the Offering Notice (such date, as may be changed pursuant to clause (i) of the immediately following sentence, the “Proposed Pricing Date”) and (iii) the manner of the sale, such as whether such it will be a Block Trade, another form of Underwritten Offering, at the market or through a private transaction. Each ROFO Seller in its sole discretion may at any time (i) change the Proposed Pricing Date, so long as such ROFO Seller provides Crestwood with advance written notice as soon as reasonably practicable under the circumstances and in no event less than 24 hours in advance of the revised Proposed Pricing Date and (ii) withdraw an Offering Notice.

Section 2.02 Rightholder Option; Exercise.

Following the delivery of the Offering Notice, Crestwood shall have the right to offer, at the times set forth in this Section 2.02, to purchase all, but not less than all, of the Subject Units at a purchase price determined by Crestwood. The right of Crestwood to offer to purchase all of the Subject Units under this Section 2.02 shall be exercisable by delivering written notice of the exercise thereof (each such offer, a “ROFO Offer” and, each such notice, a “ROFO Offer Notice”) to the ROFO Seller, (a) if the proposed sale is to be effected pursuant to an Underwritten Offering that will be marketed to investors (for the avoidance of doubt, not including a Block Trade, overnight or bought Underwritten Offering or any similar transaction), no less than two days prior to the Proposed Pricing Date and (b) if the proposed sale is to be effected in any other manner, no later than 4:15 p.m. Eastern Time on the day of the Proposed Pricing Date. Each ROFO Offer Notice shall be, subject to the following sentence, an irrevocable offer to purchase all of the Subject Units pursuant to this Section 2.02, and shall state the purchase price Crestwood is offering for the Subject Units (the “Offer Price”) and the expiration date and time of the ROFO Offer (which shall be no earlier than 11:59 p.m. Eastern Time on the Proposed Pricing Date). The failure of Crestwood to deliver a ROFO Offer Notice that conforms to the requirements set forth in this Section 2.02 on or before the deadlines set forth in this Section 2.02 shall be deemed to be a waiver of Crestwood’s right to make a ROFO Offer under this Section 2.02. A ROFO Offer shall be irrevocable until 11:59 p.m. Eastern Time on the Proposed Pricing Date, unless earlier accepted by the ROFO Seller.

Section 2.03 Sale of Subject Units.

(a) If Crestwood has delivered a ROFO Offer Notice that conforms to the requirements set forth in Section 2.02, then the ROFO Seller may, prior to 11:59 p.m. Eastern Time on the Proposed Pricing Date, accept such offer in its entirety, but not in part, by notifying Crestwood of such acceptance (the “ROFO Acceptance”). A ROFO Acceptance shall be irrevocable once communicated by such ROFO Seller to Crestwood.

(b) In the event of a ROFO Acceptance, the closing of the purchase of such Subject Units pursuant to the ROFO Offer Notice shall be held at the executive office of Crestwood at 11:00 a.m., local time, on the second Business Day after the ROFO Acceptance or at such other day, time and place as the parties to the transaction may agree (the “ROFO Closing Date”). At such closing, so long as the closing of transaction complies with all applicable securities Laws, the ROFO Seller shall deliver the Subject Units to Crestwood, and such Subject Units shall be free and clear of any Liens (other than Liens arising under securities Laws or the Partnership Agreement and the other Organizational Documents of Crestwood), and the ROFO Seller shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and record owner of such Subject Units. At the closing, Crestwood shall purchase the Subject Units by delivery of payment in full in immediately available funds for the Subject Units equal to the Offer Price. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary to effectuate the transactions contemplated by this Article II, provided that such documents shall not impose any liability on the ROFO Seller or Crestwood. If the closing of the ROFO Acceptance does not occur on the ROFO Closing Date for any reason except where such failure is caused by the ROFO Seller, then the ROFO Seller shall be free to sell the Subject Units without further complying with this Article II; provided, however, that such sale is consummated within 45 days after the Proposed Pricing Date.

(c) If Crestwood has made a ROFO Offer, and the ROFO Seller elects not to accept such ROFO Offer, then the ROFO Seller may sell the Subject Units to one or more third parties (i) as long as the purchase price for such Subject Units is, in the aggregate, not less than the Offer Price and (ii) such sale is consummated within 45 days after the Proposed Pricing Date.

(d) If Crestwood does not deliver a ROFO Offer Notice that conforms to the requirements set forth in Section 2.03(b) on or before the deadlines set forth in Section 2.03(b), then the ROFO Seller shall be free to sell the Subject Units without further complying with this Article II; provided, however, that such sale is consummated within 45 days after the Proposed Pricing Date.

(e) Any sale of Common Units by First Reserve or one of its Affiliates to Crestwood pursuant to this Article II shall not constitute a Demand Offering under Article III.

ARTICLE III

REGISTRATION RIGHTS

Section 3.01 Registration.

(a) Request for Filing and Deadline to Become Effective. As promptly as practicable and in any event no later than (i) 105 days following a written request from the Unitholder delivered prior to the date of the filing of Crestwood’s Annual Report on Form 10-K with the SEC for the year ending December 31, 2022 (the “10-K Filing Date”) or (ii) 60 days following a written request from the Unitholder delivered on or after the 10-K Filing Date, Crestwood shall prepare and file a Resale Registration Statement under the Securities Act with respect to all of the Registrable Securities. The Resale Registration Statement filed pursuant to this Section 3.01(a) shall be on such appropriate registration form of the Commission that Crestwood is eligible to use, as reasonably selected by Crestwood. Crestwood shall use its commercially reasonable efforts to cause the Resale Registration Statement to become effective as soon as reasonably practicable (and in any event within (i) 135 days of the written request from the Unitholder delivered prior to the 10-K Filing Date or (ii) 90 days of the written request from the Unitholder delivered on or after the 10-K Filing Date). Crestwood will use its commercially reasonable efforts to cause the Resale Registration Statement filed pursuant to this Article III to be continuously effective under the Securities Act until all Registrable Securities covered by the Resale Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Resale Registration Statement when declared effective (including the documents

5

incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (and, in the case of any prospectus contained in such Resale Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Resale Registration Statement becomes effective, but in any event within two Business Days of such date, Crestwood shall provide the Unitholder with written notice of the effectiveness of the Resale Registration Statement.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, Crestwood may, upon written notice to any Selling Holder whose Registrable Securities are included in the Resale Registration Statement or any other registration statement pursuant to Section 3.03, suspend such Selling Holder’s use of any prospectus that is a part of the Resale Registration Statement or any other registration statement pursuant to Section 3.03 (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the such registration statement but may settle any previously made sales of Registrable Securities) if (i) Crestwood is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and Crestwood determines in good faith that Crestwood’s ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Resale Registration Statement or any other registration statement pursuant to Section 3.03 or (ii) Crestwood has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of Crestwood, would materially adversely affect Crestwood; provided, however, in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Resale Registration Statement or any other registration statement pursuant to Section 3.03 for a period that exceeds an aggregate of 60 days in any 180-day period or 105 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such information or the termination of the condition described above, Crestwood shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Resale Registration Statement or any other registration statement pursuant to Section 3.03, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

(c) Termination of Rights. Other than as set forth otherwise in this Agreement, a Holder’s rights (and any transferee’s rights pursuant to Section 3.10) under this Article III shall terminate upon the termination of the Effectiveness Period.

Section 3.02 Demand Rights.

(a) The Unitholder shall have the right, at any time from time to time, to elect to include, other than pursuant to Section 3.01 of this Agreement, at least an aggregate of $50 million of Registrable Securities (calculated based on the Common Unit Price times the number of Registrable Securities on the date Crestwood receives an Underwritten Offering Notice) under a registration statement pursuant to an Underwritten Offering (a “Demand Offering”), pursuant to and subject to the conditions of this Section 3.02(a) of this Agreement, exercisable by delivery of a written notice to Crestwood (an “Underwritten Offering Notice”). Each Underwritten Offering Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Demand Offering and the expected price range of Registrable Securities to be sold in such Underwritten Offering. The right to initiate a Demand Offering shall not be exercised (i) in respect of more than three Underwritten Offerings or (ii) more than once in any 90-day period. Upon the delivery to Crestwood of any Underwritten Offering Notice, Crestwood shall be obligated to retain underwriters in order to permit the Unitholders to effect such sale through an Underwritten Offering as promptly as practicable after an Underwritten Offering Notice (but in no event more than 30 calendar days after the delivery of such Underwritten Offering Notice). In connection with any Underwritten Offering (including any Block Trade) under this Section 3.02, the Unitholders shall be entitled to select the Managing Underwriter or Underwriters for such Underwritten Offering, subject to the consent of Crestwood not to be unreasonably withheld, delayed or conditioned.

(b) Subject to the terms in Section 3.02(a) (including, for the avoidance of doubt, the maximum number of Demand Offerings), any time when a Resale Registration Statement is on file with the Commission and is effective, if a Unitholder wishes to engage in an underwritten registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), for at least an aggregate of $50 million of Registrable

6

Securities (calculated based on the Common Unit Price times the number of Registrable Securities on the date Crestwood receives an Underwritten Offering Notice), Crestwood shall retain underwriters for such Block Trade within 5 calendar days, notwithstanding the 30-day period in Section 3.02(a), and shall use commercially reasonable efforts to facilitate such Block Trade; provided that the Unitholder wishing to engage in the Block Trade shall reasonably cooperate with Crestwood and any underwriters prior to making such request in order to facilitate preparation of the prospectus and other offering documentation related to the Block Trade. Crestwood shall not notify any other holder of Common Units of any proposed Block Trade or overnight or bought Underwritten Offering under this Section 3.02 and will not give them the opportunity to participate in such Underwritten Offering unless required by the Niobrara RRA, the Preferred RRA or the Oasis RRA, as in effect on the date hereof.

Section 3.03 Piggyback Rights.

(a) Underwritten Offering Piggyback Rights. If at any time during the Effectiveness Period, Crestwood proposes to file a registration statement (whether for the account of itself or the account of any other security holder) other than (i) the Resale Registration Statement contemplated by Section 3.01(a), (ii) a registration statement or prospectus supplement to a registration statement in connection with registration rights granted pursuant to an agreement existing on the date hereof, (iii) a registration relating solely to employee benefit plans, (iv) a registration relating solely to a Rule 145 transaction or (v) a registration on any registration form that does not permit secondary sales, then as soon as practicable following the engagement of counsel by Crestwood to prepare the documents to be used in connection with an Underwritten Offering, Crestwood shall give notice (including notification by electronic mail) of such proposed Underwritten Offering to each Holder owning more than $10 million of then-outstanding Registrable Securities, calculated on the basis of the Common Unit Price, determined as of the date of such notice, and such notice shall offer each such Holder the opportunity to participate in any Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing, subject to any registration rights existing prior to the date hereof, and customary underwriter cutbacks; provided, however, that Crestwood shall not be required to provide such opportunity (I) to any such Holder that does not offer a minimum of $10 million of Registrable Securities (based on the Common Unit Price), or (II) to such Holders if Crestwood has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing or distribution of the Common Units in the Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 3.04(b). Any notice required to be provided in this Section 3.03(a) to Holders shall be provided on a Business Day pursuant to Section 4.01 and receipt of such notice shall be confirmed by the Holder. The Holder will have two Business Days (or one Business Day in connection with any overnight or bought Underwritten Offering) after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, Crestwood shall determine for any reason not to undertake or to delay such Underwritten Offering, Crestwood may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to Crestwood of such withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may deliver written notice (a “Piggyback Opt-Out Notice”) to Crestwood requesting that such Holder not receive notice from Crestwood of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing. Following receipt of a Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), Crestwood shall not be required to deliver any notice to such Holder pursuant to this Section 3.03(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by Crestwood pursuant to this Section 3.03(a).

(b) Termination of Piggyback Registration Rights. The Piggyback Rights under this Section 3.03 will terminate at the time that the Issued Units cease to be Registrable Securities.

Section 3.04 Procedures for Underwritten Offering.

(a) General Procedures. In connection with an Underwritten Offering under this Agreement (other than pursuant to Section 3.02 of this Agreement), Crestwood shall be entitled to select the Managing Underwriter or Underwriters in its sole discretion. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and Crestwood shall be obligated to enter into an underwriting agreement with the Managing Underwriter or Underwriters that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of equity securities. No Selling Holder may participate in an Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, Crestwood to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with Crestwood or the underwriters other than representations, warranties or agreements regarding such Selling Holder, its authority to enter into such underwriting agreement and to sell, and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by Law. If any Selling Holder disapproves of the terms of an Underwritten Offering, such Selling Holder may elect to withdraw therefrom by notice to Crestwood and the Managing Underwriter; provided, however, that any such withdrawal must be made as soon as practicable and in any event no later than the time of pricing of such Underwritten Offering. If all Selling Holders withdraw from an Underwritten Offering prior to the pricing of such Underwritten Offering, the events will not be considered an Underwritten Offering. No such withdrawal or abandonment shall affect Crestwood’s obligation to pay Registration Expenses; provided, however, if (i) certain Selling Holders withdraw from an Underwritten Offering after the public announcement at launch of such Underwritten Offering, and (ii) all Selling Holders withdraw from such Underwritten Offering prior to pricing, then the withdrawing Selling Holders shall pay for all reasonable Registration Expenses incurred by Crestwood during the period from the launch of such Underwritten Offering until the time that all Selling Holders withdraw from such Underwritten Offering.

(b) Priority Rights. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering advises Crestwood that the total amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Crestwood can be sold without having such adverse effect, with such number to be allocated, (i) in the case of an Underwritten Offering initiated by Crestwood, (A) first, to Crestwood, (B) second, to any holder of securities of Crestwood having rights of registration that are expressly senior to the Registrable Securities (the “Senior Securities”), (C) third, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of securities of Crestwood having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”), and (D) fourth, pro rata among any other holders of securities of Crestwood having registration rights, and (ii) in the case of an Underwritten Offering by any other holders of securities of Crestwood having registration rights (the “Other Holders”), (A) first, pro rata among the Other Holders, (B) second, pro rata among any other holder of Senior Securities, (C) third, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of Parity Securities, (D) fourth, to Crestwood and (E) fifth, pro rata among any other holders of securities of Crestwood having registration rights. The pro rata allocations for each Selling Holder who has requested participation in such Underwritten Offering shall be the product of (1) the aggregate number of Registrable Securities proposed to be sold in such Underwritten Offering by the Selling Holders multiplied by (2) the fraction derived by dividing (x) the number of Registrable Securities owned by such Selling Holder by (y) the aggregate number of Registrable Securities owned by all Selling Holders plus the aggregate number of Parity Securities owned by all holders of Parity Securities that are participating in the Underwritten Offering.

Section 3.05 Sale Procedures. In connection with its obligations under this Article III, Crestwood will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to the Resale Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Resale Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Resale Registration Statement;

(b) if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from a registration statement and the Managing Underwriter at any time shall notify Crestwood in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, then Crestwood shall use its reasonable best efforts to include such information in such prospectus supplement;

(c) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Resale Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Resale Registration Statement or such other registration statement or supplement or amendment thereto, and (ii) such number of copies of the Resale Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Resale Registration Statement or such other registration statement;

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Resale Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request; provided, however, that Crestwood will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

(e) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Resale Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Resale Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Resale Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(f) immediately notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Resale Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the Commission of any stop order suspending the effectiveness of the Resale Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Crestwood of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Crestwood agrees to

9

as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Crestwood personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, that Crestwood need not disclose any non-public information to any such representative unless and until such representative has entered into a confidentiality agreement with Crestwood;

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(j) cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Crestwood are then listed;

(k) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of Crestwood to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(l) provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(m) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities in advance of an Underwritten Offering or Block Trade (including, making appropriate officers of Crestwood available to participate in any “road show” presentations before analysts, and other customary marketing activities (including one-on-one meetings with prospective Unitholders of the Registrable Securities), provided, however, in the event, Crestwood, using reasonable best efforts, is unable to make such appropriate officers available to participate in connection with any “road show” presentations and other customary marketing activities (whether in person or otherwise), Crestwood shall make such appropriate officers available to participate via conference call or other means of communication in connection with no more than one “road show” presentation per Underwritten Offering);

(n) if requested by a Selling Holder, (i) incorporate in a prospectus supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and

10

(o) if any Holder could reasonably be deemed to be an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the Resale Registration Statement and any amendment or supplement thereof (a “Holder Underwriter Registration Statement”), reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s due diligence” with respect to Crestwood and satisfy its obligations in respect thereof. In addition, at any Holder’s request, Crestwood will furnish to such Holder, on the date of the effectiveness of the Holder Underwriter Registration Statement and thereafter from time to time on such dates as such Holder may reasonably request, (i) a “cold comfort” letter, dated such date, from Crestwood’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to such Holder, (ii) an opinion, dated as of such date, of counsel representing Crestwood for purposes of the Holder Underwriter Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, including a standard “10b-5” opinion for such offering, addressed to such Holder and (iii) a standard officer’s certificate from the chief executive officer or chief financial officer, or other officers serving such functions, of the general partner of Crestwood addressed to the Holder; provided, however, that with respect to any placement agent, Crestwood’s obligations with respect to this Section 3.05 shall be limited to one time, with an additional bring-down request within 30 days of the date of such documents. Crestwood will also permit legal counsel to such Holder to review and comment upon any such Holder Underwriter Registration Statement at least five Business Days prior to its filing with the Commission and all amendments and supplements to any such Holder Underwriter Registration Statement with a reasonable number of days prior to their filing with the Commission and not file any Holder Underwriter Registration Statement or amendment or supplement thereto in a form to which such Holder’s legal counsel reasonably objects. Each Selling Holder, upon receipt of notice from Crestwood of the happening of any event of the kind described in Section 3.05(f), shall forthwith discontinue offers and sales of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3.05(f) or until it is advised in writing by Crestwood that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by Crestwood, such Selling Holder will, or will request the Managing Underwriter or Underwriters, if any, to deliver to Crestwood (at Crestwood’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. Notwithstanding anything to the contrary in this Section 3.05, Crestwood will not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any Resale Registration Statement or Holder Underwriter Registration Statement, as applicable, without such Holder’s consent. If the staff of the Commission requires Crestwood to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the Resale Registration Statement or Holder Underwriter Registration Statement, as applicable and Crestwood shall have no further obligations hereunder with respect to Registrable Securities held by such Holder.

Section 3.06 Cooperation by Holders. Crestwood shall have no obligation to include Registrable Securities of a Holder in the Resale Registration Statement, or in an Underwritten Offering pursuant to Section 3.03(a), who has failed to timely furnish such information that Crestwood determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 3.07 Restrictions on Public Sale by Holders of Registrable Securities. For so long as any Common Units are Registrable Securities, each Holder agrees that it will not sell any Common Units or other equity securities of Crestwood for a period of up to 60 days following the pricing date of an Underwritten Offering of equity securities by Crestwood in which such Holder exercises its Piggyback Rights; provided, however, that the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction imposed by the underwriters on the officers, directors or any Affiliate of Crestwood. In addition, the provisions of this Section 3.07 shall not apply with respect to a Holder that (a) owns less than $10 million of Registrable Securities based on the Common Unit Price, or (b) has delivered a Piggyback Opt-Out Notice to Crestwood pursuant to Section 3.03(a). Subject to such Holder’s compliance with its obligations under the U.S. federal securities laws and its internal policies: (i) Holder, for purposes hereof, shall not be deemed to include any employees, subsidiaries or Affiliates that are effectively walled off by appropriate “Chinese Wall” information barriers approved by Holder’s legal or compliance department (and thus have not been privy to any information concerning such transaction) (a “Walled Off Person”) and (ii) the foregoing covenants in this paragraph shall not apply to any transaction by or on behalf of Holder that was effected by a Walled Off Person in the ordinary course of trading without the advice or participation of Holder or receipt of confidential or other information regarding such transaction provided by Holder to such entity.

11

Section 3.08 Expenses.

(a) Expenses. Crestwood will pay all reasonable Registration Expenses as determined in good faith by Crestwood. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition, except as otherwise provided in Section 3.09, Crestwood shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

(b) Certain Definitions.

(i) “Registration Expenses” means all expenses incident to Crestwood’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on the Resale Registration Statement pursuant to Article III and the disposition of such Registrable Securities, including all registration, filing, securities exchange listing and NYSE fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, any transfer taxes and the fees and disbursements of counsel and independent public accountants for Crestwood, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance.

(ii) “Selling Expenses” means all underwriting fees, discounts and selling commissions or similar fees or arrangements allocable to the sale of the Registrable Securities.

Section 3.09 Indemnification.

(a) By Crestwood. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Crestwood will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, employees and agents and each Person, if any, who controls such Selling Holder and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Resale Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Crestwood will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the Resale Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Crestwood, the general partner of Crestwood and each of their respective directors, officers, employees and agents and each Person, if any, who controls Crestwood within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from Crestwood to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Resale Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

12

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 3.09. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 3.09 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party (provided appropriate documentation for such expense is also submitted with such notice) as incurred; provided, however, that the indemnified party will be required to repay the indemnifying party any amounts paid to it for which it is determined the indemnified party was not otherwise entitled within five calendar days of such determination. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 3.09 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 3.09 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

(b) File with the Commission in a timely manner all reports and other documents required of Crestwood under the Securities Act and the Exchange Act at all times from and after the date hereof; and

Section 3.11 Transfer or Assignment of Registration Rights. The rights to cause Crestwood to register Registrable Securities under this Article III may only be transferred or assigned by any Unitholder to one or more transferees or assignees of Registrable Securities, subject to the transfer restrictions provided in Section 4.7 of the Partnership Agreement; provided, however, that (a) such transferee receives Registrable Securities with an aggregate value of at least $50 million at the time of such transfer, (b) Crestwood is given written notice prior to any such transfer or assignment, stating the name and address of each such transferee and identifying the securities that are being transferred or assigned, and (c) each such transferee agrees in writing to undertake responsibility for its portion of the obligations of the applicable transferor under this Agreement.

Section 3.12 Limitation on Subsequent Registration Rights.

(a) From and after the date hereof, Crestwood shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities, enter into any agreement with any current or future holder of any securities of Crestwood that would allow such current or future holder to require Crestwood to include securities in any registration statement filed by Crestwood (x) with respect to any Block Trade or any overnight or bought Underwritten Offering, on any basis, or (y) with respect to any other Underwritten Offering (except as contemplated by clause (x)), on a basis other than pari passu with, or expressly subordinate to, the priority rights set forth in Section 3.04(b) granted to the Holders of Registrable Securities hereunder.

(b) Crestwood represents and warrants that, as of the date hereof, (i) none of Crestwood or any of its Subsidiaries is party to any registration rights or similar agreement with respect to Common Units that is in effect other than (x) that certain Registration Rights Agreement, dated December 28, 2017, by and among Crestwood and CN Jackalope Holdings, LLC, as amended (the “Niobrara RRA”), (y) that certain Registration Rights Agreement, dated as of September 30, 2015, by and among Crestwood and the other parties thereto (the “Preferred RRA”), and (z) that certain Registration Rights Agreement, dated March 30, 2021, by and among Crestwood and the other parties thereto (the “PIPE RRA”) and (aa) that certain Registration Rights Agreement, dated February 1, 2022, by and among Crestwood and the other parties thereto (the “Oasis RRA”) and (ii) other than as provided in the Oasis RRA, there are no “Registrable Securities” that are Common Units (as defined in each of the Niobrara RRA and the Preferred RRA) and (iii) there are not, and could not be at any point in the future, any Senior Securities under the Niobrara RRA.

Section 3.13 Removal of Legends; Further Assurances. Crestwood will replace any legended certificates with unlegended certificates promptly upon request by any Holder or at any time after such units cease to be Registrable Securities or are exempt from registration under the Securities Act. At any time after the removal of such legend, Crestwood shall use commercially reasonable efforts to cause such Registrable Securities to be registered in the name of DTC or its nominee, maintained in book entry form on the books of DTC and allowed to be settled through DTC’s regular book-entry settlement services.

GOVERNANCE

Section 3.1 Board.

(a) Board Observation Rights.

(i) During the period commencing upon the execution and delivery of this Agreement and ending on the Board Rights Termination Date (defined below), the Parent Parties shall grant First Reserve the option and right by delivering a written notice (the “Observer Notice”), to appoint an individual, subject, in the case of any such appointee other than Gary Reaves, to the prior written consent of Parent Parties (such consent not to be unreasonably withheld, conditioned or delayed), who shall be employed by First Reserve (or its Affiliate) at the time of such appointment (the “Board Observer”), to attend all meetings (including telephonic) of the full Board in an observer capacity. The Observer Notice shall be delivered to the Parent Parties prior to the Board Observer’s attendance of any meeting of the full Board. The Board Observer shall not constitute a member of the Board and shall not be entitled to vote on, or consent to, any matters presented to the Board. The Board Observer shall have the right to attend any meeting of any committee of the full Board (each, a “Committee”).

(ii) The Parent Parties shall (A) give the Board Observer written notice of the applicable meeting or action taken by written consent at the same time and in the same manner as notice is given to the members of the Board or the members of any Committee, (B) provide the Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or written consents of the full Board) given to the members of the Board or the members of any Committee in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of the Board or such members of any Committee, and (C) provide the Board Observer with all rights to attend (whether in person or by telephone or other means of electronic communication as solely determined by the Board Observer) such meetings as a member of the Board or any Committee. The Board Observer shall agree to maintain the confidentiality of all non-public information and proceedings of the Board or any Committee and to enter into, comply with, and be bound by, in all respects, the terms and conditions of a confidentiality agreement, substantially in the form attached hereto as Annex A (the “Confidentiality Agreement”). Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Parent Parties reserve the right to exclude the Board Observer from access to any material or meeting or

5

portion thereof if the Board reasonably determines, in good faith, that such access would (x) prevent the members of the Board from engaging in attorney-client privileged communication or (y) result in a conflict of interest between one or more of the Parent Parties and First Reserve; provided, however, that (A) such exclusion shall be limited to the portion of the material and/or meeting that is the basis for such exclusion and shall not extend to any portion of the material and/or meeting that does not involve or pertain to such exclusion and (B) the Parent Parties shall provide written notice, which such written notice may be provided by e-mail, to a Board Observer at any time that the Board Observer is to be excluded from access to any material or meeting or portion thereof and the basis for such exclusion, which notice will be provided reasonably in advance of such exclusion to the extent practicable.

(iii) The rights contained in this Section 3.1(a) shall immediately cease and terminate on the earlier of such date (such earlier date, the “Board Rights Termination Date”) as First Reserve and its Affiliates (i) either (A) no longer own at least 7.5% of the total issued and outstanding Common Units of Parent or (B) have sold, transferred, or divested to third parties that are not Affiliates more than 33% of the Issued Common Units, in each case appropriately adjusted for combinations, unit splits, recapitalizations and the like occurring after the date of this Agreement or (ii) Parent Parties have appointed an FR Director to the Board pursuant to Section 3.1(a)(iv).

(iv) Composition of the Board. Upon the occurrence of a vacancy on the Board, the Parent Parties shall take all Necessary Action to cause such vacancy to be filled by the individual designated by First Reserve (such director, including any individuals subsequently designated by First Reserve pursuant to this Agreement, a “FR Director”) as promptly as reasonable practicable, and in the manner set forth in the Parent LPA or the Parent GP LLCA, as applicable, for filling such vacancy on the Board; provided, however, that in the event that no such vacancy on the Board occurs prior to January 1, 2023, the Parent Parties shall take all Necessary Action to increase the size of the Board by one seat to allow the FR Director to be appointed. The initial First Reserve director designee shall be Gary Reaves unless otherwise determined by First Reserve and thereafter shall be designated pursuant to Section 3.1(b) of this Agreement; provided, however, that any First Reserve designee other than Gary Reaves shall be subject to the prior written consent of Parent Parties (such consent not to be unreasonably withheld, conditioned or delayed). First Reserve agrees to indemnify the Parent Parties from any and all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever arising from the breach by any FR Director appointed pursuant to this Section 3.1(a)(iv) after the date hereof of the confidentiality obligations under the Confidentiality Agreement or any obligation under this Agreement.

(b) First Reserve Representation. Until the earlier to occur of First Reserve and its Affiliates (i) owning less than 7.5% of the total issued and outstanding Common Units of Parent or (ii) having sold, transferred, or divested to third parties that are not Affiliates more than 33% of the Issued Common Units, in each case appropriately adjusted for combinations, unit splits, recapitalizations and the like occurring after the date of this Agreement, the Parent Parties shall include in the slate of nominees recommended by the Board for election as directors at each applicable Unitholder Meeting (as defined below) at which directors are to be elected, if applicable, an individual designated by First Reserve that, if elected, will result in the Board having a FR Director.

6

(c) Decrease in Directors. Upon any decrease in the number of directors that First Reserve is entitled to designate for nomination to the Board pursuant to Section 3.1(b), (i) First Reserve shall take all Necessary Action to cause the FR Director to tender his or her resignation to the Board, effective immediately, and (ii) to the extent Parent GP accepts any such resignation, the corresponding vacancy on the Board shall be filled, or the number of directors constituting the whole Board decreased, in accordance with the Parent LPA or Parent GP LLCA, as applicable.

(d) Removal; Vacancies. Subject to the limitations set forth in Section 3.1, First Reserve shall have the exclusive right to a designate director for election to the Board to fill a vacancy created by reason of death, removal or resignation, including any resignation pursuant to Section 3.1(e), of any FR Director (including any committees thereof), and the Parent Parties shall take all Necessary Action to cause any such vacancies to be filled by replacement directors designated by First Reserve as promptly as reasonably practicable and in the manner set forth in the Parent LPA or the Parent GP LLCA, as applicable, for filling vacancies on the Board. Any FR Director elected by the Board to fill a vacancy pursuant to this Section 3.1(d) shall have the same remaining term as that of his or her predecessor. The Parent Parties shall take all Necessary Action such that no FR Director is removed from the Board except as permitted or required by this Agreement.

(e) Forced Resignation. First Reserve shall take all Necessary Action to cause any FR Director to resign promptly from the Board if such FR Director, as determined by the Board in good faith after consultation with outside legal counsel, (i) is prohibited or disqualified from serving as a member of the Board under any rule or regulation of the SEC or the NYSE Rules, or by applicable Law (it being acknowledged and agreed that no FR Director shall be required to be an “independent” director under any securities Laws, rules or regulations or the NYSE Rules), (ii) has engaged in acts or omissions constituting a breach of any duties that may be owed by such FR Director to Parent GP, Parent or the unitholders of Parent under applicable Law, the Parent LPA or the Parent GP LLCA, or (iii) has (A) been convicted of, or entered a plea of guilty or nolo contendere to, any crime or offense constituting a felony or any other crime involving (x) an act of theft, embezzlement, fraud or dishonesty or (y) a violation of the federal securities Laws of the United States; (B) materially violated the terms of the Parent LPA that apply equally to all directors on the Board; (C) materially violated a written policy or procedure established by Parent that applies equally to all directors on the Board; (D) willfully engaged in misconduct that is materially injurious to Parent or its Subsidiaries, monetarily or otherwise; or (E) committed an action which constitutes intentional misconduct or a knowing violation of Law if such action in either event results both in an improper substantial personal benefit to such FR Director and a material injury to Parent or its Subsidiaries. Nothing in this Section 3.1(e) or elsewhere in this Agreement shall confer any third-party beneficiary or other rights upon any Person designated hereunder as a FR Director, whether during or after such Person’s service on the Board.

(f) Committee Appointments. The Board shall not designate an executive committee or any other committee which has been delegated authority substantially similar to the authority of the full Board unless at least one FR Director is also appointed as a member of such Committee.

7

(g) Qualifications and Information. Notwithstanding anything to the contrary contained in this Agreement, each individual designated to be a FR Director shall not be prohibited or disqualified from serving as a member of the Board pursuant to the applicable securities Laws, regulations or rules or the NYSE Rules (it being acknowledged and agreed that no FR Director shall be required to be an “independent” director under any securities Laws, rules or regulations or the NYSE Rules). First Reserve shall use reasonable efforts to timely provide Parent with accurate and complete information relating to any individual designated to be a FR Director that may be required to be disclosed by Parent under the Exchange Act. In addition, at Parent’s request, First Reserve shall use reasonable best efforts to cause any individual designated to be a FR Director to complete and execute a “Director and Officer Questionnaire,” in the form required to be completed by each of the Board’s other directors, prior to being admitted to the Board or any committee thereof or standing for reelection at an annual or special meeting of the unitholders of Parent, or at such other time as may be requested by Parent.

Section 3.2 Voting Agreement. Until the termination of this Agreement pursuant to Section 4.15, First Reserve will appear in person or by proxy at each annual meeting or special meeting of unitholders of the Parent and any meeting or action by written consent of the Parent’s unitholders called or held in lieu thereof, and any adjournments, postponements, reschedulings and continuations thereof (“Unitholder Meeting”) and will vote (or procure the vote of) all voting securities of Parent beneficially owned by it in accordance with the Board’s recommendations with respect to any and all proposals submitted to the unitholders of Parent.

Section 3.3 Organizational Documents. None of the Parent Parties shall take any action, directly or indirectly, to (a) effect, or in furtherance of, any amendment to the Parent GP LLCA, the Parent LPA or any other Organizational Documents of the Parent Parties that either (x) materially adversely impacts the rights of First Reserve and its Affiliates under this Agreement or (y) disproportionately and adversely impacts the rights of the FR Directors as compared to all the directors on the Board, or (b) act in a manner inconsistent with the rights of First Reserve and its Affiliates under the terms of this Agreement.

Section 3.4 Sharing of Information. Each FR Director is permitted to disclose to First Reserve and its Affiliates confidential, non-public information about the Parent Parties and their respective Affiliates that he or she receives as a result of being a member of the Board (“Confidential Information”). Accordingly, First Reserve covenants and agrees with the Parent Parties that it will not, except with the prior written consent of Parent, directly or indirectly, disclose any Confidential Information known to it, unless (i) such information becomes known to the public through no fault of First Reserve, (ii) disclosure is required by applicable Law or court of competent jurisdiction or requested by a Governmental Entity, provided that First Reserve promptly notifies Parent of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure, (iii) such information was available or becomes available to First Reserve or its Affiliates before, on or after the date hereof, without restriction, from a source (other than Parent) without any breach of duty to Parent known to First Reserve or (iv) such information was independently developed by First Reserve or its Representatives without the use of or access to the Confidential Information. First Reserve shall be permitted to disclose Confidential Information to any Affiliate or Representative of First Reserve without the prior written consent of Parent; provided, that First Reserve shall use commercially reasonable efforts to cause any Affiliate or Representative that is to receive Confidential Information from First Reserve, to abide by the obligations and restrictions imposed by this Section 3.4 with respect to such Confidential Information; and First Reserve shall be responsible for any breach of this Section 3.4 by any such Person. None of First Reserve, its Affiliates nor any FR Director shall use Confidential Information in a manner inconsistent with applicable Law.

8

Section 3.5 Reimbursement of Expenses. Each FR Director shall be entitled to receive customary reimbursement of fees and expenses incurred in connection with his or her service as a member of the Board and/or any committee thereof in accordance with the reimbursement policy applicable to the independent directors on the Board. Each FR Director (other than a FR Director who is an employee of First Reserve) shall be compensated for his or her service on the Board in the same amounts and form of consideration as the other independent directors on the Board.

Section 3.6 Indemnification Agreements. Simultaneously with any Person becoming a FR Director, Parent GP shall execute and deliver to each such FR Director a Director and Officer Indemnification Agreement, in a form substantially consistent with those entered into by the other members of the Board, dated effective the date such FR Director becomes a member of the Board. For the avoidance of doubt, each FR Director shall constitute an “Indemnified Person” as such term is defined in the Parent LPA and shall be entitled to the rights of indemnification provided in Article V of the Parent GP LLCA.
