Prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, in trust for the benefit of holders of the Partnership Common Units (other than the Sponsor Units), Parent Common Units (which shall be in non-certificated book-entry form) issuable pursuant to this Article II, collectively sufficient to effect the delivery of the Public Holder Merger Consideration to the holders of the Partnership Common Units (other than Sponsor Units).

Upon surrender of Certificates for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Partnership Common Units shall be entitled to receive in exchange therefor (subject to withholding tax as specified in Section 2.3), as applicable, the Public Holder Merger Consideration to which such holder is entitled pursuant to Section 2.1(a)(i)(B) and a check in an amount equal to the aggregate amount of cash that such holder has a right to receive pursuant to Section 2.2(c) to which such holder is

entitled, and the Partnership Common Units represented by Certificates so surrendered shall forthwith be cancelled. If any cash payment is to be made to, or any Parent Common Units constituting any part of the Public Holder Merger Consideration is to be registered in the name of, a Person other than the Person in whose name the applicable surrendered Partnership Common Unit is registered, it shall be a condition to the payment or registration thereof that the surrendered Certificate be in proper form for transfer and that the Person requesting such payment or delivery of the Public Holder Merger Consideration pay any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Public Holder Merger Consideration (and any amounts to be paid pursuant to Section 2.2(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to this Section 2.2.

(c) Distributions with Respect to Parent Common Units. All Parent Common Units to be issued pursuant to the LP Merger shall be deemed issued and outstanding as of the Effective Time and whenever a distribution is declared by Parent in respect of the Parent Common Units, the record date for which is at or after the Effective Time, that declaration shall include distributions in respect of all Parent Common Units to be issued pursuant to the LP Merger. No distributions with respect to Parent Common Units shall be paid to the holder of any unsurrendered Certificates with respect to the Partnership Common Units represented thereby until such Certificate has been surrendered in accordance with this Article II. Subject to Laws, following surrender of any such Certificate, there shall be paid to the record holder thereof, without interest, (i) promptly after such surrender, the amount of distributions with a record date at or after the Effective Time and a payment date on or prior to the date of such surrender and not theretofore paid with respect to such Parent Common Units and (ii) at the appropriate payment date, the amount of distributions with a record date at or after the Effective Time and a payment date subsequent to the date of such surrender payable with respect to such Parent Common Units.

All Equity Consideration issued upon the surrender for exchange of Certificates representing Partnership Common Units in accordance with the terms of this Article II or, with respect to Sponsor Units, at Closing in accordance with Section 2.1(a)(iii), and any cash paid pursuant to Section 2.2(c) shall be deemed to have been issued (or paid) in full satisfaction of all rights pertaining to the Partnership Common Units previously represented by such Certificates or Sponsor Units, as applicable (other than any distribution in respect of the Partnership Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Partnership Common Units in accordance with the terms of this Agreement and the Partnership Agreement and which remains unpaid at the Effective Time). After the Effective Time, the transfer books of the Partnership shall be closed, and there shall be no further registration of transfers on the transfer books of the Surviving Entity of the Partnership Common Units that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Entity or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

- 8 -

(e) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Partnership Common Units for one year after the Effective Time shall be delivered to Parent upon demand, and any holders of Partnership Common Units who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of their claim for the Public Holder Merger Consideration and any distributions pursuant to Section 2.2(c), in each case without any interest thereon. Any amounts in the Exchange Fund remaining unclaimed by holders of Partnership Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any federal, state of the United States, local, foreign, domestic, tribal or multinational government, regulatory or administrative agency, bureau, commission, commissioner, legislature, court, arbitrator, body, entity or other authority or governmental instrumentality (each, a “Governmental Entity”) will, to the extent permitted by Law, become the property of Parent.

(f) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue and pay in exchange for such lost, stolen or destroyed Certificate the Public Holder Merger Consideration and distributions to be paid in respect of the Partnership Common Units represented by such Certificate as contemplated by this Article II.

(g) No Liability. Notwithstanding anything in this Agreement to the contrary, none of the Partnership, the General Partner, Parent, Merger Sub, GP Merger Sub, the Surviving Entity, the GP Surviving Entity, the Exchange Agent or any other Person shall be liable to any former holder of Partnership Common Units for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 2.3 Withholding. Each of Parent, Merger Sub, GP Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as Parent, Merger Sub, GP Merger Sub and the Exchange Agent are required to deduct and withhold under Law, with respect to the making of such payment (and to the extent deduction and withholding is required, such deduction and withholding may be taken in Parent Common Units), provided that, in the event Parent, Merger Sub, GP Merger Sub or the Exchange Agent reasonably determines that it is required by Law to deduct or withhold any amount from the consideration otherwise payable pursuant to this Agreement, Parent, Merger Sub, GP Merger Sub or the Exchange Agent, as applicable, shall notify the Partnership and the General Partner of such determination and the parties shall cooperate in good faith to minimize to the extent permissible under Law the amount of any such deduction or withholding, including by providing any certificates or forms that are reasonably requested to establish an exemption from (or reduction in) any such deduction or withholding. To the extent that amounts are so deducted or withheld and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. If withholding is taken in Parent Common Units, Parent, Merger Sub, GP Merger Sub or the Exchange Agent, as applicable, shall be treated as having sold such Parent Common Units for an amount of cash equal to the fair market value of such Parent Common Units at the time of such deemed sale.

Except as would not reasonably be expected to be material to the Partnership and its Subsidiaries: (A) all pipelines operated by the Partnership and its Subsidiaries have or are otherwise entitled to the benefits of all material Rights-of-Way that are necessary for the Partnership and its Subsidiaries to use and operate their respective assets and properties in the manner that such assets and properties are currently used and operated, and (B) there are no gaps (including any gap arising as a result of any breach by the Partnership or any of its Subsidiaries of the terms of any Rights-of-Way) in such Rights-of-Way that would prevent the Partnership and its Subsidiaries to use and operate their respective assets and properties in the manner that such assets and properties are currently used and operated.

Section 3.18 of the Partnership Disclosure Schedule lists the annual premiums paid by, or on behalf of, the Partnership for directors and officers liability insurance policies.

Notwithstanding the foregoing, neither the Partnership nor Parent shall be required to afford such access to the extent it would unreasonably disrupt the operations of such party or any of its Subsidiaries, would cause a violation of any agreement to which such party or any of its Subsidiaries is a party, would cause a risk of a loss of privilege to such party or any of its Subsidiaries, would constitute a violation of any Law or would interfere with the ability of such party or any of its Subsidiaries’ ability to comply with any COVID-19 Measures.

(b) The parties hereto hereby agree that all information provided to them or their respective officers, directors, employees or Representatives in connection with this Agreement and the consummation of the transactions contemplated hereby shall be governed in accordance with the confidentiality agreement, dated as of June 28, 2021, between the Sponsor and Crestwood Midstream Partners LP (the “Confidentiality Agreement”).

Each of Parent and the Partnership shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the LP Merger and the other transactions contemplated hereby. Parent shall also take any action required to be taken under any applicable state or provincial securities Laws in connection with the issuance and reservation of Parent Common Units in the LP Merger, and the Partnership shall furnish all information concerning the Partnership and its Subsidiaries and the holders of Partnership Common Units, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Combined Consent Statement/Prospectus will

- 50 -

be made by Parent or the Partnership, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other party a reasonable opportunity to review and comment thereon. Parent or the Partnership, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Parent Common Units issuable in connection with the LP Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Combined Consent Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Partnership, or any of their respective Affiliates, officers or directors, is discovered by Parent or the Partnership that should be set forth in an amendment or supplement to any of the Form S-4 or the Combined Consent Statement/Prospectus, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Law, disseminated to the unitholders of the Partnership.

(b) The General Partner shall distribute to the Partnership’s unitholders the Combined Consent Statement/Prospectus as promptly as practicable after the Form S-4 is declared effective under the Securities Act.

Parent or its Subsidiary shall provide each Offered Employee with no less than 10 days in which to accept or reject such offer of employment. At least five days prior to the Closing Date, Parent shall inform the Partnership in writing which Offered Employees have accepted an offer of employment and which Offered Employees have rejected or not timely responded to an offer of employment.

(b) Following the Effective Time and until the first anniversary of the Closing Date (the “Continuation Period”), Parent shall, or shall cause one of its Subsidiaries to, provide the Transferred Employees with (i) annual base salary or wages (as applicable) and annual cash incentive compensation opportunities, in the aggregate, that are no less favorable than the aggregate compensation opportunities provided to such Transferred Employees immediately prior to the Effective Time (including annual base salary or wages (as applicable), annual cash incentive compensation and equity-based incentive opportunities) (provided, that the foregoing shall not preclude Parent from implementing broad-based salary or other pay reduction programs, following the date of this Agreement that are made in connection with market conditions and are proportionate with reductions in salary or other pay for Parent’s other similarly situated employees) and (ii) employee benefits (excluding defined benefit and supplemental pensions and retiree medical benefits) that are no less favorable than either, at Parent’s election, (A) the other compensation and employee benefits provided to similarly-situated employees of Parent and its Subsidiaries, or (B) the other compensation and employee benefits provided to such Transferred Employees immediately prior to the Effective Time.

(c) For purposes of vesting, eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies, and disability plans and policies, determining levels of benefits (but not, for the avoidance of doubt, for purposes of benefit accrual under any defined benefit pension plan) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Transferred Employees after the Effective Time (the “New Plans”), each Transferred Employee shall be credited with his or her years of service with the Partnership, the General Partner and their respective Subsidiaries and their respective predecessors and prior employers before the Effective Time, to the same extent as such Transferred Employee was entitled, before the Effective Time, to credit for such service under any similar Benefit Plan sponsored or maintained by the Sponsor or its Affiliate (other than the Partnership or the General Partner) in which such Transferred Employee participated or was eligible to participate immediately prior to the Effective Time (such plans, collectively, the “Old

- 52 -

Plans”), provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, Parent shall use reasonable best efforts to (i) waive or cause the waiver of any limitation on benefits relating to pre-existing conditions, actively-at-work exclusions, evidence of insurability and waiting periods for the Transferred Employees under any New Plan providing medical, dental, pharmaceutical and/or vision benefits for the Transferred Employee and his or her covered dependents to the extent that such limitations are waived or otherwise inapplicable to a Transferred Employee under any comparable Old Plan as of the Closing Date and (ii) credit amounts paid under any Old Plan providing medical, dental, pharmaceutical and/or vision benefits to any Transferred Employees under any corresponding New Plan for purposes of applying deductibles, copayments, and out-of-pocket limits as though such amounts had been paid in accordance with the terms and conditions of the New Plan with respect to the plan year in which the Effective Time occurs to the extent such amounts were qualified to be taken into account for purposes of satisfying any deductible, copayment or out-of-pocket limit under the corresponding Old Plan. Furthermore, Parent shall assume and honor all vacation and paid time off days accrued by Transferred Employees prior to the Effective Time, including payment for such days upon termination of employment to the extent provided for under Law or the terms of the vacation and paid time off policies of the Partnership, General Partner and their Subsidiaries; provided, however, that the foregoing shall not restrict Parent from amending, modifying or terminating any applicable vacation or paid time off policy to the extent permitted by Law.

(d) Parent shall establish and maintain or make provision for, the establishment or continuation of a health care and dependent care flexible spending account plans applicable to the Transferred Employees and the election by any Transferred Employee under an Old Plan that includes flexible spending accounts will be continued as an election as if made under the applicable New Plan containing flexible spending accounts from the beginning of the plan year in which the Effective Time occurs.

(e) Parent shall cause its New Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement to accept a direct rollover of any Transferred Employee’s benefits under any corresponding Old Plan in which such Transferred Employee participated prior to the Effective Time, in cash.

(f) No later than the Effective Time, the General Partner or one of its Affiliates (including the Sponsor) shall pay pro-rata annual bonuses for the calendar year in which the Effective Time occurs for Transferred Employees based on the number of days from January 1 of such calendar year through the earlier of the Effective Time and December 31 of such calendar year that each Transferred Employee was employed by the Sponsor or its Affiliate during such calendar year.

(g) To the extent that a Transferred Employee is eligible as of the date hereof to receive severance benefits under the Sponsor Employee Change in Control Plan, effective as of March 31, 2012 (the “2012 Plan”), if the employment of such Transferred Employee is terminated on or prior to November 20, 2022 by Parent or its Affiliates other than for Cause (as defined in Section 5.6(g) of the Partnership Disclosure Schedule) or by a Transferred Employee for Good Reason (as defined in Section 5.6(g) of the Partnership Disclosure Schedule), Parent

- 53 -

shall, or shall cause its Affiliates to, provide such Transferred Employee with the severance benefits to which such Transferred Employee would have been entitled under the 2012 Plan, as set forth in Section 5.6(g)(i) of the Partnership Disclosure Schedule. To the extent that a Transferred Employee is eligible as of the date hereof to receive severance benefits under the Sponsor 2021 Employee Change in Control Plan (the “2021 Plan”), if the employment of such Transferred Employee is terminated by Parent or its Affiliates other than for Cause (as defined in Section 5.6(g) of the Partnership Disclosure Schedule) or by a Transferred Employee for Good Reason (as defined in Section 5.6(g) of the Partnership Disclosure Schedule), Parent shall, or shall cause its Affiliates to, provide such Transferred Employee with the greater of (A) the severance benefits to which such Transferred Employee would have been entitled under the 2021 Plan, as set forth in Section 5.6(g)(ii) of the Partnership Disclosure Schedule, or (B) the severance benefits under Parent’s or its Subsidiary’s severance plan, program or policy that is applicable to similarly-situated employees of Parent and its Subsidiaries, if any.

(h) Nothing in this Section 5.6 shall be construed as an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment or termination of any Benefit Plan in accordance with its terms. Nothing in this Section 5.6 shall limit the right of Parent, the Surviving Entities or any of their Subsidiaries to terminate the employment of any Transferred Employee at any time, subject to any rights to severance benefits accrued as of the applicable termination date pursuant to Section 5.6(g). Without limiting the generality of Section 8.13, the provisions of this Section 5.6 are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other Person shall be a third-party beneficiary of this Agreement, and nothing herein shall be construed as an amendment to any Benefit Plan or other compensation or benefit plan or arrangement (including any Parent Benefit Plan) for any purpose.

(a) Parent, Merger Sub and GP Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of any of the current or former Indemnified Parties as provided in the Organizational Documents of the Partnership, the General Partner or any Subsidiary thereof or in any agreement between the Partnership, the General Partner or any Subsidiary thereof, on the one hand, and the Indemnified Party, on the other hand, shall survive the Mergers and shall continue in full force and effect. For a period of six years from the Effective Time, Parent and the Surviving Entities shall maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the Partnership’s, the General Partner’s and any of their respective Subsidiaries’ Organizational Documents in effect immediately prior to the Effective Time (including the Organizational Documents of the Partnership and the General Partner) or in any indemnification agreements of the General Partner, the Partnership or their respective Subsidiaries with any of their respective current or former Indemnified Parties in effect immediately prior to the Effective Time, and shall not amend, repeal or otherwise modify any such provisions or the exculpation, indemnification or advancement of expenses provisions (and Parent, Merger Sub and GP Merger Sub shall not authorize or consent to any such amendment,

- 56 -

repeal or other modification) of the Surviving Entities’ certificate of limited partnership, certificate of formation, partnership agreement and limited liability company agreement, as applicable, in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former Indemnified Parties; provided, however, that all rights to indemnification in respect of any Action pending or asserted or any claim made within such period shall continue until the final disposition of such Action or resolution of such claim. From and after the Effective Time, Parent shall assume, be jointly and severally liable for, and honor, guaranty and stand surety for, and shall cause the GP Surviving Entity, Surviving Entity and its Subsidiaries to honor and perform, in accordance with their respective terms, each of the covenants contained in this Section 5.10 without limit as to time.

(b) Parent and the Surviving Entities shall jointly and severally, to the fullest extent permitted under Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current and former director, officer or employee of the Partnership, General Partner or any of their respective Subsidiaries and each Person who served as a director, officer, member, trustee, agent or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise if such service was at the request or for the benefit of the Partnership, General Partner or any of their respective Subsidiaries (each, together with such Person’s heirs, executors or administrators, an “Indemnified Party”), in each case against any costs or expenses (including advancing attorneys’ fees and expenses and other costs and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by Law; provided, however, that the Indemnified Party to whom expenses are advanced provides an undertaking consistent with the Organizational Documents of the Partnership and the General Partner to repay such amounts if it is ultimately determined that such Person is not entitled to indemnification), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative and including any matters addressed by alternative dispute resolution mechanism(s) (an “Action”), arising out of, relating to or in connection with their status, services or duties as an Indemnified Party or any action or omission by them in their capacities as such occurring or alleged to have occurred whether before or after the Effective Time (including acts or omissions in connection with such Indemnified Party serving as an officer, director, employee, agent or other fiduciary of any entity if such service was at the request or for the benefit of the Partnership and in all cases including any matters pertaining or relating to this Agreement, the transactions contemplated hereby and any approvals, determinations or processes relating to the foregoing). In the event of any such Action, the Surviving Entities shall cooperate with the Indemnified Party in the defense of any such Action.

(c) For a period of six years from the Effective Time, Parent shall cause to be maintained in effect the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the date hereof by the General Partner, Partnership and their respective Subsidiaries with respect to matters existing or arising on or before the Effective Time; provided, however, that Parent shall not be required to pay annual premiums in excess of 300% of the last annual premium paid by the Partnership prior to the date hereof (the “Maximum Amount”) in respect of the coverages required to be obtained pursuant hereto and if the cost of the coverages required to be obtained pursuant hereto exceeds the

- 57 -

Maximum Amount, Parent shall purchase as much coverage as reasonably available for the Maximum Amount. If the Partnership in its sole discretion elects, then the Partnership may, prior to the Effective Time, purchase (and prepay in full the aggregate premium for) a “tail policy,” that by its terms survives the Effective Time and the transactions contemplated hereby, with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such or relating to their status, service or duties as Indemnified Parties (with such policy having at least the same coverage and amounts and containing terms and conditions that are no less favorable to the covered individuals as existing policies); provided that in no event shall the Partnership be permitted to pay as the cost of such policy in excess of six times the Maximum Amount and, if such a “tail policy” is purchased, Parent shall have no further obligations under this Section 5.10(c) other than that the Surviving Entity shall, and Parent shall cause the Surviving Entity to, maintain such policies in full force and effect, and continue to honor the obligations thereunder.

(d) Parent shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 5.10.

(f) In the event Parent, the Surviving Entities 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 in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Entities, as the case may be, shall assume the obligations of such party set forth in this Section 5.10. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the General Partner, Partnership or any of their respective Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 5.10 is not prior to, or in substitution for, any such claims under any such policies.

(g) Following the Effective Time, the obligations of Parent and the Surviving Entities under this Section 5.10 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.10 applies without the consent of such Indemnified Party. It is expressly agreed that, notwithstanding any other provision of this Agreement that may be to the contrary, (i) following the Effective Time, the Indemnified Parties to whom this Section 5.10 applies shall be third-party beneficiaries of this Section 5.10, and (ii) this Section 5.10 shall survive consummation of the Mergers and shall, following the Effective Time, be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives against Parent and the Surviving Entity and their respective successors and assigns.

Section 5.12 Section 16 Matters. Prior to the Effective Time, Parent and the Partnership shall take all such steps as may be required to cause any dispositions of Partnership Common Units (including derivative securities with respect to Partnership Common Units) or acquisitions of Parent Common Units (including derivative securities with respect to Parent Common Units) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Partnership or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.13 Tax Matters.

(a) Parent, Parent GP, the Partnership and the General Partner each acknowledges and agrees that, for U.S. federal (and applicable state and local) income tax purposes, (i) the GP Merger is intended to be treated as a taxable sale of the assets of General Partner to Parent in exchange for the GP Merger Consideration and the assumption of the General Partner’s liabilities, (ii) the LP Merger is intended to be treated as an “assets-over” partnership merger transaction under Treasury Regulations Sections 1.708-1(c)(1) and 1.708-1(c)(3)(i), whereby the Partnership is treated as the terminating partnership and Parent is treated as the resulting partnership, (iii) to the extent of the Cash Consideration, the LP Merger is intended to be treated as a taxable sale of Partnership Common Units by the Sponsor occurring immediately prior to the LP Merger in accordance with Treasury Regulations Section 1.708-1(c)(4), and (iv) none of Parent, the Partnership, the General Partner, nor any partner or member, as the case may be, of Parent, the Partnership or the General Partner is intended to recognize taxable income or gain (other than any income or gain resulting from (A) any decrease in partnership liabilities pursuant to Section 752 of the Code, (B) from the deemed sale of Parent Common Units pursuant to Section 2.3, (C) the payment of the Cash Consideration, (D) the receipt of any Equity Consideration that is not pro rata (including as a result of the excess of the Public Holder Exchange Ratio over the Sponsor Exchange Ratio), (E) a disguised sale attributable to contributions of cash or other property to the Partnership after the date of this Agreement and prior to the Effective Time, (F) the receipt of the GP Merger Consideration, (G) the application of Section 897 of the Code and the Treasury Regulations thereunder to any non-U.S. holder of Partnership Common Units that has beneficially owned more than five percent of the total Partnership Common Units, at any time in the five year period ending on the Closing Date or (H) the enactment or amendment of special gain recognition rules applicable to Persons other than corporations that hold Partnership Common Units that were received in exchange for Incentive Distribution Rights (as defined in the Partnership Agreement)) (the “Intended Tax Treatment”). Unless required to do so as a result of a “determination” as defined in Section 1313(a) of the Code, each of Parent, Parent GP, the Partnership and the General Partner agrees not to make any tax filings or otherwise take any position inconsistent with the Intended Tax Treatment and to cooperate with the other parties to make any filings, statements, or reports required to effect, disclose or report the Intended Tax Treatment.

- 59 -

(b) Each of Parent and the Partnership shall (and shall cause its respective Subsidiaries to) use its reasonable best efforts to cause the LP Merger to be treated, and will not take or knowingly fail to take (and will cause its Subsidiaries not to take or knowingly fail to take) any actions that would reasonably be expected to prevent or impede the LP Merger from being treated in accordance with the Intended Tax Treatment.

(c) Each of Parent, Parent GP, the General Partner and the Partnership shall use its reasonable best efforts and shall reasonably cooperate with one another to obtain the opinions of counsel referred to in Section 6.1(f), Section 6.2(e) and Section 6.3(d) (the “Required Tax Opinions”).

(d) Parent shall (i) prepare and file any U.S. federal (and applicable state and local) income Tax Returns for the Partnership for the taxable year including the Closing Date (and any prior taxable years for which such returns are not yet filed as of Closing) in accordance with the past practices of the Partnership (other than reflecting a closing of the books under Section 706 of the Code on the Closing Date), and (ii) provide the Sponsor with access to such Partnership files, work papers and other materials as the Sponsor may reasonably request to confirm that such Tax Returns have been prepared in accordance with the past practices of the Partnership.

Without limiting the generality of the foregoing, the Partnership and the General Partner shall, and shall cause their respective Subsidiaries and shall use commercially reasonable efforts to cause each of their respective officers, employees and Representatives to, upon reasonable request of Parent or any of its officers, employees or Representatives (and solely to the extent customary or necessary in connection with such financing): (1) furnish the report of the Partnership’s auditor on the three most recently available audited consolidated financial statements of the Partnership and its Subsidiaries (as and when available in the ordinary course of business of the Partnership and Subsidiaries) and use its commercially reasonable efforts to obtain the consent of such auditor to the use of such reports, including in documents filed with the SEC under the Securities Act, in accordance with normal custom and practice and use commercially reasonable efforts to cause such auditor to provide customary comfort letters to the arrangers, underwriters, initial purchasers or placement agents, as applicable, in connection with any such financing; and (2) use commercially reasonable efforts to (i) furnish any customary additional financial statements, schedules, business or other financial data relating to the Partnership and its Subsidiaries as may be reasonably necessary to consummate any such financing, including for the preparation of any pro forma financial information or pro forma financial statements required pursuant to the Securities Act or as may be customary and reasonably necessary in connection with any such financing (it being understood, in any event, that Parent shall be solely responsible for the preparation of any such pro forma financial information and/or pro forma financial statements); (ii) provide customary direct contact between (x) senior management and advisors, including auditors, of the Partnership and (y) the proposed arrangers, lenders, underwriters, initial purchasers or placement agents, as applicable, and/or Parent’s auditors, as applicable, in connection with any such financing, at reasonable times during regular business hours, and upon reasonable advance notice; (iii) reasonably assist in the preparation of (but not, in each case of the following, entering into or executing) documents, certificates (excluding as to solvency), and other agreements (including indentures or supplemental indentures) and take other actions that are or may be customary in connection with any such financing or reasonably necessary or desirable to permit Parent or its Subsidiaries to fulfill conditions or obligations under the financing documents, provided that such agreements shall be conditioned upon, and shall not take effect until, the Effective Time; (iv) reasonably assist in the pledging of collateral of the Partnership and its Subsidiaries (including obtaining deposit and security account control agreements or similar third party agreements), provided that such pledges shall be conditioned upon, and shall not take effect until, the Effective Time; (v) reasonably assist in the preparation of one or more customary confidential information memoranda, prospectuses, offering memoranda and other marketing and syndication materials reasonably requested by Parent and reasonably necessary for such financing; (vi) permit Parent or its Subsidiaries’ customary use of

In addition, no action, liability, or

- 62 -

obligation of the General Partner, the Partnership, any of its Subsidiaries, or any of their respective officers, employees and Representatives pursuant to any agreement, arrangement, contract, certificate, instrument, or other document relating to any such financing will be effective until the Effective Time, and none of the General Partner, the Partnership, nor any of its Subsidiaries will be required to take any action pursuant to any of the foregoing that is not contingent on the occurrence of the Closing or that must be effective before the Effective Time. Further, nothing in this Section 5.16 will require (1) the General Partner, the Partnership, its Subsidiaries, or their respective officers, employees and Representatives to execute, deliver or enter into, or perform any agreement, document or instrument, including any definitive financing document, with respect to any financing or adopt resolutions approving the agreements, documents or instruments pursuant to which any financing is obtained or pledge any collateral with respect to any financing prior to Closing, (2) any officer, employee or Representative of the General Partner, the Partnership or any of its Subsidiaries to deliver any certificate or take any other action under this Section 5.16 that could reasonably be expected to result in personal liability to such officer or Representative, (3) the Representatives of the General Partner, the Partnership or its Subsidiaries to deliver any legal opinions with respect to such financing or (4) the General Partner, the Partnership, its Subsidiaries, or their respective officers, employees and Representatives to prepare and/or deliver any financial information in a form not customarily prepared by such Person with respect to such period.

The Partnership shall use commercially reasonable efforts to cooperate with Parent in replacing any letters of credit issued pursuant to the facilities evidencing the above referenced indebtedness or obligations.

At all times prior to [•], if Sponsor 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), Sponsor 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 2.03), pursuant to the terms of this Section 2.03, 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.

(b) Rightholder Option; Exercise.

(i) Following the delivery of the Offering Notice, Crestwood shall have the right to offer, at the times set forth in this Section 2.03(b), 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 2.03(b) shall be exercisable by delivering written notice of the exercise thereof (each such offer, a “ROFO Offer” and, each such notice, a

5

“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 2.03(b), 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 2.03(b) on or before the deadlines set forth in this Section 2.03(b) shall be deemed to be a waiver of Crestwood’s right to make a ROFO Offer under this Section 2.03. 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.

(c) Sale of Subject Units.

(i) If Crestwood has delivered a ROFO Offer Notice that conforms to the requirements set forth in Section 2.03(b), 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.

(ii) 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 Section 2.03, 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 Section 2.03; provided, however, that such sale is consummated within 45 days after the Proposed Pricing Date.

(iii) 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 (A) as long as the purchase price for such Subject Units is, in the aggregate, not less than the Offer Price and (B) such sale is consummated within 45 days after the Proposed Pricing Date.

6

(iv) 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 Section 2.03; provided, however, that such sale is consummated within 45 days after the Proposed Pricing Date.

(v) Any sale of Common Units by Sponsor or one of its Affiliates to Crestwood pursuant to this Section 2.03 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. No later than 60 days following the date hereof (except if Crestwood is not then eligible to register for resale the Registrable Securities on Form S-3, in which case, not later than 90 days), 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 90 days of the date hereof). 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 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 Unitholders 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

7

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 Unitholders shall have the right, at any time from time to time, to elect to include, other than pursuant to Section 2.01 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) and Section 2.01, 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 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

8

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 PIPE RRA (provided that no notice will be provided under the PIPE RRA after March 30, 2022), 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

9

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.

10

(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, (C) fourth, to Crestwood and (D) 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;

11

(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

12

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 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);

13

(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

(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

14

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, such Holder shall no longer be entitled to received Liquidated Damages under this Agreement with respect thereto 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.

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.

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

16

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.

(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

17

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.

Section 3.10 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, Crestwood agrees to use its commercially reasonable efforts to:

(a) Make and keep public information regarding Crestwood available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(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

(c) So long as a Holder owns any Registrable Securities, furnish, unless otherwise available at no charge by access electronically to the Commission’s EDGAR filing system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Crestwood, and such other reports and documents so filed with the Commission as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

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.

18

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 all 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”), (ii) 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. Crestwood agrees that, prior to January 1, 2024, it shall not exercise any of its rights under that certain Third Amended and Restated Limited Liability Company Agreement of Crestwood Niobrara LLC, dated as of April 9, 2019, that would result in Registrable Securities that are Common Units existing 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.

Notwithstanding anything to the contrary contained in this Agreement, each individual designated to be a Sponsor 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 Sponsor Director shall be required to be an “independent” director under any securities Laws, rules or regulations or the NYSE Rules). Sponsor shall use reasonable efforts to timely provide Parent with accurate and complete information relating to any individual designated to be a Sponsor Director that may be required to be disclosed by Parent under the Exchange Act.

Section 3.2 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 Sponsor and its Affiliates under this Agreement or (y) disproportionately and adversely impacts the rights of the Sponsor Directors as compared to all the directors on the Board, or (b) act in a manner inconsistent with the rights of Sponsor and its Affiliates under the terms of this Agreement.

Section 3.3 Sharing of Information. Each Sponsor Director is permitted to disclose to Sponsor 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, Sponsor 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 Sponsor, (ii) disclosure is required by applicable Law or court of competent jurisdiction or requested by a Governmental Entity, provided that Sponsor 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 Sponsor 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 Sponsor or (iv) such information was independently developed by Sponsor or its Representatives without the use of or access to the Confidential Information. Sponsor shall be permitted to disclose Confidential Information to any Affiliate or Representative of Sponsor without the prior written consent of Parent; provided, that Sponsor shall use commercially reasonable efforts to cause any Affiliate or Representative that is to receive Confidential Information from Sponsor, to abide by the obligations and restrictions imposed by this Section 3.3 with respect to such Confidential Information; and Sponsor shall be responsible for any breach of this Section 3.3 by any such Person. None of Sponsor, its Affiliates nor any Sponsor Director shall use Confidential Information in a manner inconsistent with applicable Law.

Section 3.4 Reimbursement of Expenses. Each Sponsor 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 Sponsor Director (other than a Sponsor Director who is an employee of Sponsor) 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 3.5 Indemnification Agreements. Simultaneously with any Person becoming a Sponsor Director, Parent GP shall execute and deliver to each such Sponsor 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 Sponsor Director becomes a member of the Board. For the avoidance of doubt, each Sponsor 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.

Section 4.13 Definitions. All capitalized terms not otherwise defined in this Agreement shall have the meanings given them under the Merger Agreement.

Section 4.14 Freedom to Pursue Opportunities.

11

Person, or does not present such opportunity to the Parent Parties or any of their respective Subsidiaries; provided, that any such business, activity or transaction described in this Section 4.14 is not the direct result of Sponsor, its Affiliates or a Sponsor Director using Confidential Information in violation of Section 3.3 hereof. Notwithstanding anything to the contrary contained in this Section 4.14, any Sponsor Director may be excluded, by the members of the Board who are not Sponsor Directors, from any discussion or vote on matters in accordance with a conflicts of interest policy of the Board that is adopted by the Board in good faith and is applicable to all of the members of the Board.

Section 4.15 Termination. This Agreement shall terminate automatically (without any action by any Party) upon the time at which Sponsor or any of its Affiliates no longer has the right to designate an individual for nomination to the Board under this Agreement, and upon such termination, Sponsor’s rights and obligations shall cease; provided, that the provisions in Section 3.3 and this Article IV shall survive such termination.

[***]

(ii) Effective as of the Effective Date, Section 4.2 of the Crude Oil Agreement—Wild Basin is hereby deleted in its entirety and replaced with the following:

“If this Agreement is terminated pursuant to the terms and conditions of this Agreement on or after December 31, 2032, then Shipper shall have the option (to be exercised by providing written notice to Gatherer prior to the termination of the Agreement) to continue to receive the Services or a portion of the Services, under a new agreement, for all or any portion of its volumes of Crude Oil on a year-to-year basis on the same terms and conditions as the most favorable terms and conditions under a then-effective agreement with any third party pursuant to which Gatherer provides a basket of services for an initial term (excluding any renewals or extensions of any kind) of at least [***] for volumes of Crude Oil utilizing any System Segment located within the “Most Favored Nations Dedication Area” as identified on Exhibit K attached hereto (other than any pipeline facilities physically connected or independent of a System Segment after the Effective Date, in each case, in connection with an acquisition, joint venture, or partnership by and between Gatherer and a third party), that are the same or substantially similar in nature to the basket of Services during the term hereunder, unless and until such third party agreement is terminated. For avoidance of doubt, the Services Gatherer is to offer Producer in accordance with the proceeding sentence shall only apply to Services on the Gathering System.

If the option to extend the term of this Agreement on a year-to-year basis pursuant to this Section 4.2 is exercised, any obligation of Gatherer to continue to provide the Services pursuant to such option shall not extend beyond December 31, 2042. Gatherer shall provide copies to Shipper of any such third party agreements applicable to volumes of Crude Oil accessing the Gathering System upon any notice of termination of this Agreement (whether such notice is delivered by Gatherer, Producer or Shipper); provided, however, that to the extent Gatherer is prohibited by an obligation of confidentiality from disclosing any such third party agreement to Shipper, then (a) Gatherer shall not be obligated to disclose such agreement to Shipper until Gatherer has obtained the right to disclose such agreement and (b) Gatherer shall exercise reasonable efforts to obtain the right to disclose such agreement to Shipper.”

(iii) Effective as of the Effective Date, Section 7.4 of the Crude Oil Agreement—Wild Basin is hereby deleted in its entirety and replaced with the following:

“Subject to the rest of the provisions of this Section 7.4, Producer will (i) use reasonable efforts to obtain access to electrical power at each CDP and (ii) provide electrical power to Gatherer at each CDP at Producer’s sole cost and expense. In designing and constructing its electrical facilities at each CDP, Producer will cooperate with Gatherer and take into account the amount of electrical power that is reasonably necessary for Gatherer’s facilities to receive Producer’s Crude Oil at each such CDP. If a generator is necessary for electrical power to be used by Producer and Gatherer, then Producer shall procure, install, operate, and maintain such generator to fulfill the power requirements of the Parties and Gatherer shall pay its prorated portion of the reasonable capital costs (including reasonable rental and installation costs) therefor; provided, however, that Producer will continue to use all reasonable efforts to obtain access to electrical power at such CDP, thereby minimizing the time such generator is needed (rather than a local electric utility) to provide electrical power at such CDP.”

3

(iv) Effective as of the Effective Date, the following sentence is hereby added as Section 9.2(e) of the Crude Oil Agreement—Wild Basin:

“Except to protect operational or pipeline integrity, to prevent injury to Persons or damage to property, or as required by Applicable Law, Gatherer (or Gatherer’s affiliates) shall not amend the quality provisions of the Crude Oil Tariff regarding the Johnson’s Corner Pipeline System without OPM’s written consent, which consent shall not be unreasonably withheld, conditioned, or delayed.”

“Producer and Shipper shall have the right to assign their collective rights under this Agreement, in whole or in part, as applicable, without the consent of Gatherer, to any Person with a credit rating equal to or better than Producer’s credit rating as of the Effective Date and to whom Producer sells, assigns or otherwise Transfers all or any portion of the Dedicated Properties and who assumes in writing all of Producer’s and Shipper’s obligations hereunder (if applicable, to the extent of the Dedicated Properties being Transferred to such Person) and, upon such assignment, each of Producer and Shipper shall be released from their respective obligations under this Agreement to the extent of such assignment. If the Person to whom Producer intends to sell, assign or otherwise Transfer all or any portion of the Dedicated Properties has a credit rating worse than Producer’s credit rating as of the Effective Date, then, Producer shall have the right to assign its rights under this Agreement, in whole or in part, as applicable, without the consent of Gatherer, to such Person if, as a condition precedent to such assignment, at Producer’s option, either: (A) Producer and the assignee execute an amendment to this Agreement with Gatherer that sets forth creditworthiness requirements to which Gatherer agrees such assignee will be subject under this Agreement for the remainder of the term, or (B) grants Gatherer (or its designee) the exclusive right to market and sell all of such assignee’s Crude Oil received into the Gathering System (thereby waiving all take-in-kind rights thereto) and to remit payment to such assignee, on a Monthly basis, of the net proceeds from the sale of such Crude Oil (after deducting the Fees and any other applicable fees or costs incurred under this Agreement and any other agreement between such assignee and Gatherer (or its Affiliate)) during such Month in accordance with Article 12, or (C) Producer remains liable for its obligations under this Agreement to the extent of such assignment, or (D) the assignee agrees to provide a letter of credit from a major U.S. commercial bank for the benefit of Gatherer in an amount equal to 60 days of the aggregated Fees under this Agreement that are reasonably estimated to become due and payable by assignee upon the assignment; provided that, upon such assignment, in each case of (A), (B) and (D), Producer shall be released from its obligations under this Agreement to the extent of such assignment.”
