Section 2.03 Right of First Offer.

(a) Offering Notice. At all times prior to February 1, 2024, 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 “ROFO Offer Notice”) to the ROFO Seller, (A) if the proposed sale is to be effected pursuant to an Underwritten Offering

5

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 pursuant to Section 3.03

7

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 for such Block Trade within 5 calendar days, notwithstanding the 30-day period in

8

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 in

9

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

10

launch of such Underwritten Offering, and (ii) all Selling Holders withdraw from such Underwritten Offering prior to pricing, then the withdrawing Selling Holders shall pay for all reasonable Registration Expenses incurred by Crestwood during the period from the launch of such Underwritten Offering until the time that all Selling Holders withdraw from such Underwritten Offering.

(b) Priority Rights. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering advises Crestwood that the total amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price, timing or distribution of the Common Units offered or the market for the Common Units, then the Common Units to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises Crestwood can be sold without having such adverse effect, with such number to be allocated, (i) in the case of an Underwritten Offering initiated by Crestwood, (A) first, to Crestwood, (B) second, to any holder of securities of Crestwood having rights of registration that are expressly senior to the Registrable Securities (the “Senior Securities”), (C) third, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of securities of Crestwood having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity Securities”), and (D) fourth, pro rata among any other holders of securities of Crestwood having registration rights, and (ii) in the case of an Underwritten Offering by any other holders of securities of Crestwood having registration rights (the “Other Holders”), (A) first, pro rata among the Other Holders, (B) second, pro rata among any other holder of Senior Securities, (C) third, pro rata among the Selling Holders who have requested participation in such Underwritten Offering and any other holder of Parity Securities, (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 qualification of any Registrable Securities for sale under the applicable securities or blue sky laws

12

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 Act in any Resale Registration Statement or Holder Underwriter

14

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.

15

(b) Certain Definitions.

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

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

Section 3.09 Indemnification.

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

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Crestwood, the general partner of Crestwood and each of their respective directors, officers, employees and agents and each Person, if any, who controls Crestwood within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from Crestwood to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Resale Registration Statement or any other registration statement contemplated by this Agreement, any

16

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 proceeds (net of Selling Expenses)

17

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.

GOVERNANCE

Section 3.1 Board.

(a) Composition of the Board. (i) Prior to or simultaneously with the execution of this Agreement, the Parent Parties shall have taken all necessary action to expand the size of the Board as necessary to add two directors to the Board and (ii) simultaneously with execution of this Agreement, the Board shall elect two directors designated by Sponsor (each, including any individuals subsequently designated by Sponsor pursuant to this Agreement, a “Sponsor Director”), who initially shall be John Jacobi and N. John Lancaster, Jr. and thereafter shall be designated pursuant to Section 3.1(b) of this Agreement. One such Sponsor Director shall be a Class II member of the Board (whose term shall expire at the 2023 annual meeting of limited partners of Parent) and the other shall be a Class III member of the Board (whose term shall expire at the 2024 annual meeting of limited partners of Parent).

(b) Sponsor Representation. For so long as Sponsor and its Affiliates hold the Percentage of Parent Common Unit Ownership shown in the table below, the Parent Parties shall include in the slate of nominees recommended by the Board for election as directors at each applicable annual or special meeting of unitholders of Parent at which directors are to be elected, if applicable, that number of individuals designated by Sponsor that, if elected, will result in the Board having the number of Sponsor Directors that is shown in the table below.

(c) Decrease in Directors. Upon any decrease in the number of directors that Sponsor is entitled to designate for nomination to the Board pursuant to Section 3.1(b), (i) Sponsor shall take all Necessary Action to cause the appropriate number of Sponsor Directors to tender their resignation to the Board (and if only one Sponsor Director is required to resign, as determined by Sponsor in its sole discretion), effective immediately, and (ii) to the extent Parent GP accepts any such resignation, the corresponding vacancy on the Board shall be filled, or the number of directors constituting the whole Board decreased, in accordance with the Parent LPA or Parent GP LLCA, as applicable.

5

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

(e) Forced Resignation. Sponsor shall take all Necessary Action to cause any Sponsor Director to resign promptly from the Board if such Sponsor Director, as determined by the Board in good faith after consultation with outside legal counsel, (i) is prohibited or disqualified from serving as a member of the Board under any rule or regulation of the SEC or the NYSE Rules, or by applicable Law, (ii) has engaged in acts or omissions constituting a breach of any duties that may be owed by such Sponsor Director to Parent GP, Parent or the unitholders of Parent under applicable Law, the Parent LPA or the Parent GP LLCA, or (iii) has (A) been convicted of, or entered a plea of guilty or nolo contendere to, any crime or offense constituting a felony or any other crime involving (x) an act of theft, embezzlement, fraud or dishonesty or (y) a violation of the federal securities Laws of the United States; (B) materially violated the terms of the Parent LPA that apply equally to all directors on the Board; (C) materially violated a written policy or procedure established by Parent that applies equally to all directors on the Board; (D) willfully engaged in misconduct that is materially injurious to Parent or its Subsidiaries, monetarily or otherwise; or (E) committed an action which constitutes intentional misconduct or a knowing violation of Law if such action in either event results both in an improper substantial personal benefit to such Sponsor Director and a material injury to Parent or its Subsidiaries. Nothing in this Section 3.1(e) or elsewhere in this Agreement shall confer any third-party beneficiary or other rights upon any Person designated hereunder as a Sponsor Director, whether during or after such Person’s service on the Board.

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

(g) Qualifications and Information. 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. In addition, at Parent’s request, Sponsor shall use reasonable efforts to cause any individual designated to be a Sponsor Director to complete and execute a “Director and Officer Questionnaire,” in the form required to be completed by each of the Board’s other directors, prior to being admitted to the Board or any committee thereof or standing for reelection at an annual or special meeting of the unitholders of Parent, or at such other time as may be requested by Parent.

6

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 4.3 Jurisdiction; Specific Enforcement. The Parties agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed, or were threatened to be not performed, in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other remedy that may be available to it at law or in equity, each of the Parties shall be entitled to an injunction or injunctions or equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, solely if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), and all such rights and remedies at law or in equity shall be cumulative. The Parties further agree that no Party to this Agreement shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 4.3 and each Party waives any objection to the imposition of such relief or any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

To the fullest extent permitted by Law, each of the Parties hereto hereby consents to the service of process in accordance with Section 4.5; provided, however, that nothing herein shall affect the right of any Party to serve legal process in any other manner permitted by Law.

DIRECTOR AND OFFICER INDEMNIFICATION AGREEMENT

This Director and Officer Indemnification Agreement, dated as of [                ], 20[ ] (this “Agreement”), is made by and between Crestwood Equity GP LLC, a Delaware limited liability company (the “Company”), and [                ] (“Indemnitee”).

RECITALS:

WHEREAS, the Company is the general partner of Crestwood Equity Partners LP, a Delaware limited partnership (the “Partnership”), and Indemnitee is either a member of the board of directors of the Company (the “Board”) or an officer of the Company, or both, and in such capacity is performing a valuable service for the Company;

WHEREAS, Section 4.1 of the Second Amended and Restated Limited Liability Company Agreement of the Company (the “LLC Agreement”) provides that the business and affairs of the Company shall be managed by or under the direction of the Board;

WHEREAS, the Company is aware that competent and experienced persons are increasingly reluctant to serve as directors or officers of corporations or other business entities unless they are protected by comprehensive indemnification and liability insurance, due to increased exposure to litigation costs and risks resulting from their service to such corporations, and because the exposure frequently bears no reasonable relationship to the compensation of such directors and officers;

WHEREAS, the Board has concluded that, to retain and attract talented and experienced individuals to serve or continue to serve as officers or directors of the Company, and to encourage such individuals to take the business risks necessary for the success of the Company, it is necessary for the Company contractually to indemnify directors and officers and to assume for itself to the fullest extent permitted by law expenses and damages related to claims against such officers and directors in connection with their service to the Company;

WHEREAS, Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”), under which the Company is organized, empowers the Company to enter into agreements to indemnify and advance expenses to its officers, directors, employees and agents, and persons who serve, at the request of the Company, as directors, officers, employees or agents of other corporations or enterprises, and expressly provides that the indemnification provided by the DGCL is not exclusive;

WHEREAS, Indemnitee is a director or officer of the Company and does not regard the protection afforded to him or her by Delaware law and the LLC Agreement as adequate, and her willingness to serve in such capacity is predicated, in substantial part, upon (1) the Company’s willingness to provide protection to her pursuant to express contract rights providing for the Company to indemnify her in accordance with the principles reflected above, to the fullest extent permitted by Delaware law, and (2) the other undertakings set forth in this Agreement;

WHEREAS, in recognition of the need to provide Indemnitee with substantial protection against personal liability, in order to procure Indemnitee’s continued service as a director or officer of the Company and to enhance Indemnitee’s ability to serve the Company in an effective manner, and in order to provide such protection pursuant to express contract rights (intended to be enforceable irrespective of, among other things, any amendment to the Company’s certificate of formation (the “Certificate”) or the LLC Agreement (collectively, the “Constituent Documents”), any

1

change in the composition of the Board or any change-in-control or business combination transaction relating to the Company), the Company wishes to provide in this Agreement for (1) the indemnification of and the advancement of Expenses (as defined in Section 1(h) below) to Indemnitee as set forth in this Agreement and (2) the continued coverage of Indemnitee under the Company’s directors’ and officers’ liability insurance policies;

WHEREAS, in light of the considerations referred to in the preceding recitals, it is the Company’s intention and desire that the provisions of this Agreement be construed liberally, subject to their express terms, to maximize the protections to be provided to Indemnitee hereunder.

WHEREAS, it is intended that Indemnitee shall be paid promptly by the Company all amounts necessary to effectuate in full the rights provided herein; and

WHEREAS, this Agreement is a supplement to and in furtherance of the rights to indemnification and advancement of expenses, and related rights, provided in the Certificate, the LLC Agreement, the Sixth Amended and Restated Agreement of Limited Partnership of the Partnership dated August 20, 2021 and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder;

NOW, THEREFORE, in consideration of the foregoing and the Indemnitee’s agreement to continue to provide services to the Company, the parties hereby agree as follows:

AGREEMENT:

1. Certain Definitions. In addition to terms defined elsewhere herein, the following terms have the following meanings when used in this Agreement with initial capital letters:

(a) “Affiliate” means, with respect to any Person, any other Person that directly or indirectly through one or more intermediaries controls, is controlled by or is under common control with, the Person in question. As used herein, the term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a Person, whether through ownership of voting securities, by contract or otherwise.

(b) “Beneficial Owner” has the meaning given to the term “beneficial owner” in Rule 13d-3 under the Exchange Act.

(c) “Change in Control” shall mean a change in control of the Company occurring after the date of this Agreement of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Exchange Act, regardless of whether the Company is then subject to such reporting requirement. Without limiting the foregoing, such a Change of Control shall be deemed to have occurred if, after the date of this Agreement, (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 promulgated under the Exchange Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company’s then outstanding securities entitled to vote generally in the election of directors without the prior approval of at least two-thirds of the members of the Board in office immediately prior to such person attaining such percentage interest; (ii) the Company is a party to a merger, consolidation, sale of assets or other reorganization, or a proxy contest, as a consequence of which members of the Board in office immediately prior to such transaction or event constitute less than a majority of the Board thereafter; (iii) during any period of two consecutive years, individuals who at the beginning of such period constituted the Board (including for

2

this purpose any new director whose election or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such period) cease for any reason to constitute at least a majority of the Board; or (iv) approval by the stockholders of the Company of a liquidation or dissolution of the Company.

The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable shall be presumed conclusively to be reasonable.

2. Service to the Company. Indemnitee agrees to serve as a director or officer of the Company for so long as Indemnitee is duly elected or appointed or until Indemnitee tenders her resignation or is no longer serving in such capacity. This Agreement shall not be deemed an employment agreement between the Company (or any of its Subsidiaries or Controlled Affiliates) and Indemnitee. Indemnitee specifically acknowledges that her service to the Company or any of its Subsidiaries or Controlled Affiliates is at will and the Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written agreement between Indemnitee and the Company (or any of its Subsidiaries or Controlled Affiliates), or other applicable formal severance policies duly adopted by the Board or, with respect to service as a director or officer of the Company, by the Company’s Constituent Documents or Delaware law. This Agreement shall continue in force after Indemnitee has ceased to serve as a director or officer of the Company or, at the request of the Company, or any of its Subsidiaries or Controlled Affiliates, as provided in Section 12 hereof.

3. Indemnification Obligation. Subject to Section 7 and Section 8 of this Agreement, the Company shall indemnify, defend and hold harmless Indemnitee, to the fullest extent permitted by the laws of the State of Delaware in effect on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted indemnification, against any and all Indemnifiable Claims and Indemnifiable Losses.

4. Advancement of Expenses. Indemnitee shall have the right to advancement by the Company, prior to the final disposition of any Indemnifiable Claim to which there are no further rights of appeal, of any and all Expenses relating to, arising out of or resulting from any Indemnifiable Claim actually and reasonably paid or incurred by Indemnitee or which Indemnitee determines are reasonably likely to be paid or incurred by Indemnitee. Indemnitee’s right to such advancement is not subject to the satisfaction of any standard of conduct. Without limiting the generality or effect of the foregoing, within five business days after any request by Indemnitee, the Company shall, in accordance with such request (but without duplication), (a) pay such Expenses on behalf of Indemnitee, (b) advance to Indemnitee funds in an amount sufficient to pay such Expenses, or (c) reimburse Indemnitee for such Expenses. In connection with any request for advancement of such Expenses (“Expense Advances”), Indemnitee shall not be required to provide any documentation or information to the extent that the provision thereof would undermine or otherwise jeopardize attorney-client privilege. In connection with any request for Expense Advances, Indemnitee shall execute and deliver to the Company an undertaking (which shall be accepted without reference to Indemnitee’s ability to repay the Expense Advances), in the form attached hereto as Exhibit A, to repay any amounts paid, advanced, or reimbursed by the Company for such Expenses to the extent that it is ultimately determined, following the final disposition of such Claim, that Indemnitee is not entitled to indemnification hereunder. Indemnitee’s obligation to reimburse the Company for Expense Advances shall be unsecured and no interest shall be charged thereon.

5

5. Indemnification for Expenses in Enforcing Rights. Without limiting the generality or effect of the foregoing and to the fullest extent allowable under applicable law, the Company shall also indemnify against and, if requested by Indemnitee, shall advance to Indemnitee subject to and in accordance with Section 3, any and all Expenses actually and reasonably paid or incurred by Indemnitee or which Indemnitee determines are reasonably likely to be paid or incurred by Indemnitee in connection with any Claim made, instituted or conducted by Indemnitee for (a) indemnification or reimbursement or advance payment of Expenses by the Company under any provision of this Agreement, or under any other agreement or provision of the Constituent Documents now or hereafter in effect relating to Indemnifiable Claims, and/or (b) recovery under any directors’ and officers’ liability insurance policies maintained by the Company, regardless in each case of whether Indemnitee ultimately is determined to be entitled to such indemnification, reimbursement, advance or insurance recovery, as the case may be; provided, however, that Indemnitee shall return, without interest, any such advance of Expenses (or portion thereof) which remains unspent at the final disposition of the Claim to which the advance related. Notwithstanding anything to the contrary herein, Indemnitee shall be required to reimburse the Company in the event that a final judicial determination is made that such action brought by Indemnitee was frivolous or not made in good faith.

6. Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any Indemnifiable Loss, but not for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.

7. Notification and Defense of Claims.

(a) Notification of Claims. Indemnitee shall notify the Company in writing as soon as practicable of any Indemnifiable Claim or Indemnifiable Loss for which Indemnitee could seek Expense Advances, including a brief description (based upon information then available to Indemnitee) of the nature of, and the facts underlying, such Indemnifiable Claim or Indemnifiable Loss. If, at the time of the receipt of such notice, the Company has directors’ and officers’ liability insurance in effect under which coverage for such Indemnifiable Claim or Indemnifiable Loss is potentially available, the Company shall give prompt written notice of such Indemnifiable Claim or Indemnifiable Loss to the applicable insurers in accordance with the procedures set forth in the applicable policies. The Company shall provide to Indemnitee a copy of such notice delivered to the applicable insurers, and copies of all subsequent correspondence between the Company and such insurers regarding the Indemnifiable Claim or Indemnifiable Loss, in each case substantially concurrently with the delivery or receipt thereof by the Company. The failure by Indemnitee to timely notify the Company of any Indemnifiable Claim or Indemnifiable Loss shall not relieve the Company from any liability hereunder unless, and only to the extent that, the Company did not otherwise learn of such Indemnifiable Claim or Indemnifiable Loss and such failure results in forfeiture by the Company of substantial defenses, rights or insurance coverage.

(b) Defense of Claims. The Company shall be entitled to participate in the defense of any Indemnifiable Claim at its own expense and, except as otherwise provided below, to the extent the Company so wishes, it may assume the defense thereof with counsel reasonably satisfactory to Indemnitee. After notice from the Company to Indemnitee of its election to assume the defense of any Indemnifiable Claim, the Company shall not be liable to Indemnitee under this Agreement or otherwise for any Expenses subsequently directly incurred by Indemnitee in connection with Indemnitee’s defense

6

of such Indemnifiable Claim other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ her own legal counsel in such Indemnifiable Claim, but all Expenses related to such counsel incurred after notice from the Company of is assumption of the defense shall be at Indemnitee’s own expenses; provided, however, that if (i) Indemnitee’s employment of its own legal counsel has been authorized by the Company, (ii) Indemnitee has reasonably determined that there may be a conflict of interest between Indemnitee and the Company in the defense of such Indemnifiable Claim, (iii) after a Change in Control, Indemnitee’s employment of its counsel has been approved by the Independent counsel, (iv) the use of counsel chosen by the Company to represent Indemnitee would present such counsel with an actual or potential conflict, (v) the named parties in any such Indemnifiable Claim (including any impleaded parties) include both the Company and Indemnitee and Indemnitee shall conclude that there may be one or more legal defenses available to him or her that are different from or in addition to those available to the Company, (vi) any such representation by counsel chosen by the Company would be precluded under the applicable standards of professional conduct then prevailing or (vii) the Company shall not in fact have employed counsel to assume the defense of such Indemnifiable Claim, then Indemnitee shall be entitled to retain separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any particular Indemnifiable Claim) and all Expenses related to such separate counsel shall be borne by the Company.

8. Procedure upon Application for Indemnification. In order to obtain indemnification pursuant to this Agreement, Indemnitee shall submit to the Company a written request therefor, including in such request such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of the Indemnifiable Claim, provided that documentation and information need not be so provided to the extent that the provision thereof would undermine or otherwise jeopardize attorney-client privilege. Indemnification shall be made insofar as the Company determines Indemnitee is entitled to indemnification in accordance with Section 9 below.

9. Determination of Right to Indemnification.

(a) Mandatory Indemnification; Indemnification as a Witness.

(i) To the extent that Indemnitee shall have been successful on the merits or otherwise in defense of any Indemnifiable Claim or any portion thereof or in defense of any issue or matter therein, including dismissal without prejudice, Indemnitee shall be indemnified against all Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim in accordance with Section 3 to the fullest extent allowable by law, and no Standard of Conduct Determination (as defined in Section 9(b)) shall be required.

(ii) To the extent that Indemnitee’s involvement in an Indemnifiable Claim is to prepare to serve and serve as a witness, and not as a party, the Indemnitee shall be indemnified against all Indemnifiable Losses incurred in connection therewith to the fullest extent allowable by law, and no Standard of Conduct Determination (as defined in Section 9(b)) shall be required.

7

(b) Standard of Conduct. To the extent that the provisions of Section 9(a) are inapplicable to an Indemnifiable Claim that shall have been finally disposed of, any determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law that is a legally required condition precedent to indemnification of Indemnitee hereunder against Indemnifiable Losses relating to, arising out of or resulting from such Indemnifiable Claim and any determination that Expense Advances must be repaid to the Company (a “Standard of Conduct Determination”) shall be made as follows:

(i) if a Change in Control shall not have occurred, or if a Change in Control shall have occurred but Indemnitee shall have requested that the Standard of Conduct Determination be made pursuant to this clause (i), (A) by a majority vote of the Disinterested Directors, even if less than a quorum of the Board, (B) if such Disinterested Directors so direct, by a majority vote of a committee of Disinterested Directors designated by a majority vote of all Disinterested Directors, or (C) if there are no such Disinterested Directors, by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee; and

(ii) if a Change in Control shall have occurred and Indemnitee shall not have requested that the Standard of Conduct Determination be made pursuant to clause (i), by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee.

Indemnitee will cooperate with the person or persons making such Standard of Conduct Determination, including providing to such person or persons, upon reasonable advance request, any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. The Company shall indemnify and hold harmless Indemnitee against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five business days of such request, any and all Expenses incurred by Indemnitee in so cooperating with the person or persons making such Standard of Conduct Determination.

(c) Making the Standard of Conduct Determination. The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required under Section 9(b) to be made as promptly as practicable. If (i) the person or persons empowered or selected under Section 9(b) to make the Standard of Conduct Determination shall not have made a determination within 30 days after the later of (A) receipt by the Company of written notice from Indemnitee for indemnification pursuant to Section 8 (the date of such receipt being the “Notification Date”) and (B) the selection of an Independent Counsel, if such determination is to be made by Independent Counsel, that is permitted under the provisions of Section 9(e) to make such determination and (ii) Indemnitee shall have fulfilled her obligations set forth in the first sentence of the last paragraph of Section 9(b), then Indemnitee shall be deemed to have satisfied the applicable standard of conduct; provided that such 30-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person or persons making such determination in good faith requires such additional time for the obtaining or evaluation or documentation and/or information relating thereto. Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of any Indemnifiable Claim.

(d) Payment of Indemnification. If (i) Indemnitee shall be entitled to indemnification hereunder against any Indemnifiable Losses pursuant to Section 9(a), (ii) no Standard of Conduct Determination is legally required as a condition to indemnification of Indemnitee hereunder against any Indemnifiable Losses, or (iii) Indemnitee has been determined or deemed pursuant to Section 9(b) or 9(c) to have satisfied any applicable Standard of Conduct Determination, then the Company shall pay to Indemnitee, within five business days after the later of (A) the Notification Date in respect of the

8

Indemnifiable Claim or portion thereof to which such Indemnifiable Losses are related, out of which such Indemnifiable Losses arose or from which such Indemnifiable Losses resulted and (B) the earliest date on which the applicable criterion specified in clause (i), (ii) or (iii) above shall have been satisfied, an amount equal to the amount of such Indemnifiable Losses.

(e) Selection of Independent Counsel for Standard of Conduct Determination. If a Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 9(b)(i), the Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising her of the identity of the Independent Counsel so selected. If a Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 9(b)(ii), the Independent Counsel shall be selected by Indemnitee, and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either case, Indemnitee or the Company, as applicable, may, within five business days after receiving written notice of selection from the other, deliver to the other a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not satisfy the criteria set forth in the definition of “Independent Counsel” in Section 1(m), and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person or firm so selected shall act as Independent Counsel. If such written objection is properly and timely made and substantiated, (i) the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit and (ii) the non-objecting party may, at its option, select an alternative Independent Counsel and give written notice to the other party advising such other party of the identity of the alternative Independent Counsel so selected, in which case the provisions of the two immediately preceding sentences and clause (i) of this sentence shall apply to such subsequent selection and notice. If applicable, the provisions of clause (ii) of the immediately preceding sentence shall apply to successive alternative selections. If no Independent Counsel that is permitted under the foregoing provisions of this Section 9(e) to make the Standard of Conduct Determination shall have been selected within 30 days after the Company gives its initial notice pursuant to the first sentence of this Section 9(e) or Indemnitee gives its initial notice pursuant to the second sentence of this Section 9(e), as the case may be, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware (“Delaware Court”) to resolve any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person or firm selected by the Court or by such other person as the Delaware Court shall designate, and the person or firm with respect to whom all objections are so resolved or the person or firm so appointed will act as Independent Counsel. In all events, the Company shall pay all of the reasonable fees and expenses of the Independent Counsel incurred in connection with the Independent Counsel’s determination pursuant to Section 9(b).

(f) Presumption and Defenses.

(i) Indemnitee’s Entitlement to Indemnification. In making any Standard of Conduct Determination, the person or persons making such determination shall presume that Indemnitee has satisfied the applicable standard of conduct and is entitled to indemnification, and the Company may overcome such presumption only by its adducing clear and convincing evidence to the contrary. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by Indemnitee in the Delaware Court. No determination by the Company (including by its directors or any

9

Independent Counsel) that Indemnitee has not satisfied any applicable standard of conduct shall be a defense to any legal proceedings brought by Indemnitee to secure indemnification or reimbursement or advance payment of Expenses by the Company hereunder or create a presumption that Indemnitee has not met any applicable standard of conduct.

(ii) Reliance as a Safe Harbor. For purposes of this Agreement, and without creating any presumption as to a lack of good faith if the following circumstances do not exist, Indemnitee shall be deemed to have acted in good faith and in a manner she reasonably believed to be in or not opposed to the best interest of the Company if Indemnitee’s actions or omissions to act are taken in good faith reliance upon the records of the Company, including its financial statements, or upon information, opinions, reports or statements furnished to Indemnitee by the officers or employees of the Company or any of its subsidiaries in the course of their duties, or by committees of the Board or by any other Person (including legal counsel, accountants and financial advisors) as to matters Indemnitee reasonably believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Company. In addition, the knowledge and/or actions, or failures to act, of any director, officer, agent or employee of the Company shall not be imputed to Indemnitee for purposes of determining the right to indemnity hereunder.

(iii) No Other Presumptions. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, will not create a presumption that Indemnitee did not meet any applicable standard of conduct or have any particular belief, or that indemnification hereunder is otherwise not permitted.

(iv) Defense to Indemnification and Burden of Proof. It shall be a defense to any action brought by Indemnitee against the Company to enforce this Agreement (other than an action brought to enforce a claim for Indemnifiable Losses incurred in defending against an Indemnifiable Claim in advance of its final disposition) that it is not permissible under applicable law for the Company to indemnify Indemnitee for the amount claimed. In connection with any such action or any related Standard of Conduct Determination, the burden of proving such a defense or that the Indemnitee did not satisfy the applicable standard of conduct shall be on the Company.

(v) Resolution of Claims. The Company acknowledges that a settlement or other disposition short of final judgment may be successful on the merits or otherwise for purposes of Section 9(a)(i) if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any Indemnifiable Claim to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement or such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise for purposes of Section 9(a)(i). The Company shall have the burden of proof to overcome this presumption.

10. Exclusions from Indemnification. Notwithstanding anything in this Agreement to the contrary, the Company shall not be obligated to:

(a) indemnify or advance funds to Indemnitee for Expenses or Losses with respect to proceedings initiated by Indemnitee, including any proceedings against the Company or its directors, officers, employees or other indemnitees and not by way of defense, except:

(i) proceedings referenced in Section 5 above (unless a court of competent jurisdiction determines that each of the material assertions made by Indemnitee in such proceeding was not made in good faith or was frivolous); or

10

(ii) where the Company has joined in or the Board has consented to the initiation of such proceedings.

(b) indemnify Indemnitee if a final decision by a court of competent jurisdiction determines that such indemnification is prohibited by applicable law.

(c) indemnify Indemnitee for the disgorgement of profits arising from the purchase or saleby Indemnitee of securities of the Company in violation of Section 16(b) of the Exchange Act, or any similar successor statute.

(d) indemnify or advance funds to Indemnitee for Indemnitee’s reimbursement to the Company or any bonus or other incentive-based or equity-based compensation previously received by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements under Section 304 of the Sarbanes-Oxley Act of 2002 in connection with an accounting restatement of the Company or the payment to the Company of profits arising from the purchase or sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act).

11. Settlement of Claims. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid in settlement of any threatened or pending Indemnifiable Claim effected without the Company’s prior written consent; provided, however, that if a Change in Control has occurred, the Company shall be liable for indemnification of the Indemnitee for amounts paid in settlement if an Independent Counsel has approved the settlement. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid in settlement of any threatened or pending Indemnifiable Claim effected without the Company’s prior written consent. The Company shall not, without the prior written consent of Indemnitee, effect any settlement of any threatened or pending Indemnifiable Claim in any manner that would impose any Losses on Indemnitee or to which Indemnitee is, or could have been, a party unless such settlement solely involves the payment of money and includes a complete and unconditional release of Indemnitee from all liability on any claims that are the subject matter of such Indemnifiable Claim. Neither the Company nor Indemnitee shall unreasonably withhold its consent to any proposed settlement; provided that Indemnitee may withhold consent to any settlement that does not provide a complete and unconditional release of Indemnitee.

12. Duration. All agreements and obligations of the Company contained herein shall continue during the period that Indemnitee is a director or officer of the Company (or is serving at the request of the Company as a director, officer, employee, member, trustee or agent of a Controlled Affiliate) and shall continue thereafter (i) so long as Indemnitee may be subject to any possible Indemnifiable Claim (including any rights of appeal thereto) and (ii) throughout the pendency of any proceeding (including any rights of appeal thereto) commenced by Indemnitee to enforce or interpret her rights under this Agreement, even if, in either case, she may have ceased to serve in such capacity at the time of any such Indemnifiable Claim or proceeding.

13. Non-Exclusivity. The rights of Indemnitee hereunder will be in addition to any other rights Indemnitee may have under the Constituent Documents, or the substantive laws of the Company’s jurisdiction of formation, any other contract or otherwise (collectively, “Other Indemnity Provisions” ); provided, however, that (a) to the extent that Indemnitee otherwise would have any greater right to indemnification under any Other

11

Indemnity Provision, Indemnitee will be deemed to have such greater right hereunder and (b) to the extent that any change is made to any Other Indemnity Provision which permits any greater right to indemnification than that provided under this Agreement as of the date hereof, Indemnitee will be deemed to have such greater right hereunder. Except as set forth in the proviso to the immediately preceding sentence, the Other Indemnity Provisions shall not be taken into account in construing or applying the provisions of this Agreement, which are intended to operate independently of the Other Indemnity Provisions. The Company will not adopt any amendment to any of the Constituent Documents the effect of which would be to deny, diminish or encumber Indemnitee’s right to indemnification under this Agreement or any Other Indemnity Provision.

14. Liability Insurance and Funding. For the duration of Indemnitee’s service as a director of the Company, and thereafter for so long as Indemnitee shall be subject to any pending or possible Indemnifiable Claim, the Company shall use commercially reasonable efforts (taking into account the scope and amount of coverage available relative to the cost thereof) to cause to be maintained in effect policies of directors’ and officers’ liability insurance providing coverage for directors and/or officers of the Company that is at least substantially comparable in scope and amount to that provided by the Company’s current policies of directors’ and officers’ liability insurance. Upon request, the Company shall provide Indemnitee with a copy of all directors’ and officers’ liability insurance applications, binders, policies, declarations, endorsements and other related materials, and shall provide Indemnitee with a reasonable opportunity to review and comment on the same. Without limiting the generality or effect of the two immediately preceding sentences, the Company shall not discontinue or significantly reduce the scope or amount of coverage from one policy period to the next (i) without the prior approval thereof by a majority vote of the Incumbent Directors, even if less than a quorum, or (ii) if at the time that any such discontinuation or significant reduction in the scope or amount of coverage is proposed there are no Incumbent Directors, without the prior written consent of Indemnitee (which consent shall not be unreasonably withheld or delayed). In all policies of directors’ and officers’ liability insurance maintained by the Company, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee the same rights and benefits, subject to the same limitations, as are provided to the most favorably insured of the Company’s directors, if Indemnitee is a director, or of the Company’s officers, if Indemnitee is an officer (and not an a director) by such policy. The Company may, but shall not be required to, create a trust fund, grant a security interest or use other means, including a letter of credit, to ensure the payment of such amounts as may be necessary to satisfy its obligations to indemnify and advance expenses pursuant to this Agreement.

15. Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee against other Persons (other than Indemnitee’s successors), including any entity or enterprise referred to in clause (i) of the definition of “Indemnifiable Claim” in Section 1(k).

The Company and Indemnitee each hereby irrevocably and unconditionally (a) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court and not in any other state or federal court in the United States, (b) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement, and (c) waive, and agree not to plead or make, any claim that the Delaware Court lacks venue or that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.

In the event that any court of competent jurisdiction or other adjudicative body shall decline to reform any provision of this Agreement held to be invalid, unenforceable or otherwise illegal as contemplated by the immediately preceding sentence, the parties hereto shall take all such action as may be necessary or appropriate to replace the provision so held to be invalid, unenforceable or otherwise illegal with one or more alternative provisions that effectuate the purpose and intent of the original provisions of this Agreement as fully as possible without being invalid, unenforceable or otherwise illegal.

0. Amendments and Waivers. No supplement, modification or amendment of thisAgreement shall be binding unless executed in writing by both parties hereto. No wavier of any of the provisions of this Agreement shall be binding unless in the form of a writing signed by the party against whom enforcement of the waiver is sought, and no such waiver shall operate as a waiver of any other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. Except as specifically provided herein, no failure to exercise or delay in exercising any right or remedy hereunder shall constitute a waiver thereof. No agreements or representations, oral or otherwise, expressed or implied with respect to the subject matter hereof have been made by either party that are not set forth expressly in this Agreement.

21. Legal Fees and Expenses. It is the intent of the Company that Indemnitee not be required to incur legal fees and or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. Accordingly, without limiting the generality or effect of any other provision hereof, if it should appear to Indemnitee that the Company has failed to comply with any of its obligations under this Agreement or in the event that the Company or any other Person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, the Company irrevocably authorizes Indemnitee from time to time to retain counsel of Indemnitee’s choice, at the expense of the Company as hereafter provided, to advise and represent Indemnitee in connection with any such interpretation, enforcement or defense, including the initiation or defense of any litigation or other legal action, whether by or against the Company or any director, officer, member or other person affiliated with the Company, in any jurisdiction. Notwithstanding any existing or prior attorney-client relationship between the Company and such counsel, the Company irrevocably consents to Indemnitee’s entering into an attorney-client relationship with such counsel, and in that connection the Company and Indemnitee agree that a confidential relationship shall exist between Indemnitee and such counsel. Without respect to whether Indemnitee prevails, in whole or in part, in connection with any of the foregoing, the Company will pay and be solely financially responsible for any and all attorneys’ and related fees and expenses incurred by Indemnitee in connection with any of the foregoing.

NEWS RELEASE

Crestwood Announces Changes to the Board of Directors

2/1/2022

HOUSTON-(BUSINESS WIRE)– Crestwood Equity Partners LP (NYSE: CEQP) (“Crestwood”) announced today, following the completion of its acquisition of Oasis Midstream Partners LP (“Oasis Midstream”), changes to the Board of Directors of its general partner.

In connection with the recently closed merger with Oasis Midstream, Oasis Petroleum Inc. (Nasdaq: OAS) (“Oasis Petroleum”) received the contractual right to appoint two members to the Crestwood Board of Directors, subject to ongoing ownership thresholds. As a result, Crestwood is pleased to welcome Mr. John Jacobi and Mr. John Lancaster, Jr. to the Crestwood board, effective February 1, 2022.

Mr. Jacobi will serve on the Sustainability Committee of the Crestwood board. He currently serves on the board of Oasis Petroleum, where he is the Chair of Compensation Committee and a member of the Audit & Reserves Committee. Mr. Jacobi brings significant experience in the energy industry, particularly through his knowledge and expertise in exploration and production sector, and currently serves as the President and CEO of Javelin Energy Partners, a subsidiary of Crescent Energy. In 2013, Mr. Jacobi co-founded Covey Park Energy, Inc. and served as its co-CEO and board member until the company was sold to Comstock Resources in 2019. Mr. Jacobi started his career with Woolf & McGee Inc. and later founded Jacobi-Johnson Energy, Inc. which was then sold to EXCO Resources. Mr. Jacobi has previously served on the board of directors of Comstock Resources and Pioneer Energy Services Corp, and he holds a Bachelor of Science in Biology from West Texas A&M University.

Mr. Lancaster will serve on the Compensation and Finance Committees of the Crestwood board. He currently serves on the board of Oasis Petroleum as a member of the Compensation Committee and the Nominating, Environmental, Social & Governance Committee. Mr. Lancaster contributes significant financial knowledge and investment experience to the Crestwood board. He is currently a Managing Partner of Oyster Creek, LLC, an investment and advisory from established in 2020, and serves on the Board of Directors for Aquadrill LLC, a provider of deepwater oshore drilling services globally. Mr. Lancaster was previously with Riverstone Holdings, LLC, where he spent 20 years investing in and developing companies across the energy industry, including the midstream sector in North America and Europe.

Mr. Lancaster holds a Bachelor of Business Administration from the University of Texas and a Master of Business Administration from Harvard Business School.

“As we close the Oasis Midstream merger, I am pleased to welcome John Jacobi and John Lancaster to the Crestwood board. They are veterans of the energy industry and we will benet from their extensive experience in the upstream and financial sectors. The addition of these independent directors will further strengthen Crestwood’s leading MLP corporate governance model and our important working relationship with Oasis Petroleum. The new Crestwood board, comprised of a combination of legacy Crestwood directors, recently recruited independent directors and Oasis Petroleum appointees will be well suited to drive Crestwood’s long-term strategy through a disciplined, returns focused business model of generating positive free cashflow while maintaining financial strength and exibility, as we focus on building unitholder value,” stated Robert G. Phillips, Chairman, Founder and Chief Executive Ocer of Crestwood’s general partner.

Additionally, effective January 31, 2022, Mr. Alvin Bledsoe has resigned from the Board of Directors and as Chair of the Audit Committee. Mr. Bledsoe’s resignation was as result of a post-merger potential independence issue related to Oasis Petroleum’s current audit from and was not due to any disagreement or concern regarding Crestwood, its auditors, or its management team. Ms. Angela Minas, currently a member of the Audit Committee, will take over the role of Chair.

Mr. Phillips added, “On behalf of the Crestwood organization, I want to thank Al Bledsoe for his many years of dedicated service to the Crestwood board. As an original director of Quicksilver Gas Services, a Crestwood predecessor company acquired in 2010, Al has provided wise counsel and seasoned perspective to our management team as we shaped the partnership over the last decade through multiple acquisitions and divestitures. With his help, our board has provided solid strategic guidance to position the company where it is today as a midstream leader in sustainability, transparency and operational excellence.”

Following these changes, the Crestwood Board of Directors will consist of ten members of which 90% are independent, 30% are female representatives, and 50% have three or less years of tenure. In 2021, Crestwood transitioned to a publicly elected board and will hold its rst board elections and annual unitholders meeting in May 2022.
