No tax deficiency has been determined adversely to any of the CEQP Entities which has had (nor do any of the CEQP Entities have any notice or knowledge of any tax deficiency of the CEQP Entities which could reasonably be expected to be determined adversely to any of the CEQP Entities and which could reasonably be expected to have) a Material Adverse Effect.

2. Sale of Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, CEQP and each Manager agree that CEQP may from time to time seek to sell Units through a Manager, acting as sales agent as follows:

(a) CEQP may submit its orders to the applicable Manager by telephone (including any price, time or size limits or other customary parameters or conditions) to sell Units on any Trading Day (as defined herein) which order shall be promptly confirmed by such Manager (and accepted by CEQP) by electronic mail using a form substantially similar to that attached hereto as Exhibit A (the “Transaction Confirmation”). CEQP may sell Units through no more than one Manager on any Trading Day. As used herein, “Trading Day” shall mean any trading day on the Exchange, other than a day on which the Exchange is scheduled to close prior to its regular weekday closing time.

(b) Subject to the terms and conditions hereof, the applicable Manager shall use its commercially reasonable efforts to execute any CEQP order submitted to it hereunder to sell Units (pursuant to the parameters and conditions designated by CEQP pursuant to Section 2(a) above) and with respect to which such Manager has agreed to act as sales agent. CEQP acknowledges and agrees that (i) there can be no assurance that such Manager will be successful in selling the Units, (ii) such Manager will incur no liability or obligation to CEQP or any other person or entity if it does not sell Units for any reason other than a failure by such Manager to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units as required under this Agreement and (iii) such Manager shall be under no obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the CEQP Parties in writing pursuant to a Terms Agreement.

(c) CEQP shall not authorize the issuance and sale of, and the applicable Manager shall not sell, any Unit at a price lower than the minimum price therefor designated by CEQP pursuant to Section 2(a) above. In addition, CEQP or such Manager may, upon notice to the other party hereto by telephone (confirmed promptly by email or facsimile), suspend or terminate an offering of the Units pursuant to this Agreement; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice. During any such period of suspension, CEQP shall not be obligated to deliver (or cause to be delivered) any of the documents referred to in Sections 5(b), (c), (d) or (f), be deemed to affirm any of the representations or warranties contained in this Agreement pursuant to Section 2(e) hereof, or be obligated to conduct any due diligence session as referred to in Section 6(s) until the termination of the suspension and the recommencement of the offering of the Units pursuant to this Agreement (which recommencement shall constitute a Representation Date (as defined below)). For the avoidance of doubt, any period during which CEQP has not provided instructions with respect to the sale of Units pursuant to Section 2(a) hereof, or any period during which such instruction provided thereunder has been properly revoked by CEQP, shall not be deemed a suspension of the program under this Agreement.

(d) The applicable Manager shall provide written confirmation (which may be by facsimile or email) to CEQP following the close of trading on the Exchange each day in which Units are sold under this Agreement setting forth (i) the amount of Units sold on such day, (ii) the gross offering proceeds received from such sale and (iii) the commission payable by CEQP to such Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from such Manager to CEQP, with payment to be made by CEQP promptly after its receipt thereof.

(e) Subject to the terms of a Terms Agreement, the Units may be offered and sold (x)(i) by means of ordinary brokers’ transactions that qualify for delivery of a Prospectus in accordance with Rule 153 of the Securities Act and meet the definition of an “at the market offering” under Rule 415(a)(4) of the Securities Act, (ii) to or through a market maker, or (iii) directly on or through any other national securities exchange or facility thereof, a trading facility of a national securities association, an alternative trading system, an electronic communication network, a “dark pool” or any similar market venue and (y) such other sales of the Units on behalf of CEQP in its capacity as agent of CEQP as shall be agreed by CEQP and such Manager in writing. Subject to the terms of a Terms Agreement, the Managers may also sell Units by any other method permitted by law, including but not limited to in privately negotiated transactions.

(f) At each Time of Sale, Settlement Date and Representation Date, CEQP shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, but modified to incorporate the disclosures contained in the Registration Statement and the Prospectus, in each case as amended or supplemented as of such date. Any obligation of the applicable Manager to use its commercially reasonable efforts to sell the Units on behalf of CEQP as sales agent shall be subject to the continuing accuracy of the representations and warranties (as modified in the manner described above) of CEQP herein, to the performance by CEQP of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 5 of this Agreement.

(g) If any party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other parties and sales of the Units under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(h) Notwithstanding any other provision of this Agreement, CEQP and the Managers agree that no sales of Units shall take place, CEQP shall not request the sales of any Units that would be sold and the Managers shall not be obligated to sell or offer to sell, during any period in which CEQP’s insider trading policy, as it exists on the date of this Agreement, would prohibit the purchase or sale of Common Units by persons subject to such policy, or during any other period in which CEQP is, or could be deemed to be, in possession of material non-public information.

(i) The Managers shall not have any obligation to purchase Units as principal, whether from CEQP or otherwise, unless CEQP and the applicable Managers agree as set forth below. Units purchased from CEQP by the applicable Managers, individually or in a syndicate, as principal shall be made in accordance with terms agreed upon between such Managers and the CEQP Parties as evidenced by a Terms Agreement. The applicable Managers’ commitment to purchase Units from CEQP as principal shall be deemed to have been made on the basis of the accuracy of the representations and warranties of the CEQP Parties, and performance by the CEQP Parties of their covenants and other obligations herein contained and shall be subject to the terms and conditions herein set forth. At the time of each Terms Agreement, the applicable Managers shall specify the requirements, if any, for the officers’ certificate, opinions and letters of counsel and accountants’ letter pursuant to Section 5(b)–(f) hereof. In the event of a conflict between the terms of this Equity Distribution Agreement and a Terms Agreement, the terms of such Terms Agreement shall control

3. Fee. The compensation to a Manager for sales of the Units with respect to which such Manager acts as sales agent hereunder shall be up to 2.0% of the gross offering proceeds of the Units sold pursuant to this Agreement by such Manager. The foregoing rate of compensation shall not apply when any Manager acts as principal, in which case CEQP may sell Units to such Manager as a principal at a price mutually agreed upon at the relevant Time of Sale pursuant to a Terms Agreement.

4. Payment, Delivery and Other Obligations. Unless otherwise specified in the applicable Transaction Confirmation, settlement for sales of Units will occur on the third Trading Day (or such earlier day as is (i) required by applicable law or rules or regulations or (ii) industry practice for regular-way trading and mutually agreed upon by the Managers and CEQP) following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Units sold through the applicable Manager for settlement on such date shall be issued and delivered by CEQP to such Manager against payment of the net proceeds from the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units by CEQP or its transfer agent to such Manager’s or its designee’s account (provided that such Manager shall have given CEQP written notice of such designee prior to the Settlement Date) at The Depository Trust Company or by such other means of delivery as may be mutually agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, in return for payment in same day funds delivered to the account designated by CEQP. If CEQP, or its transfer agent (if applicable), shall default on its obligation to deliver

the Units on any Settlement Date, CEQP shall (i) hold the applicable Manager harmless against any loss, claim, damage, or expense (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by CEQP and (ii) pay such Manager any commission, discount or other compensation to which it would otherwise be entitled absent such default.

(o) On each Representation Date, CEQP shall cause to be furnished to the Managers, dated as of such date, in form and substance satisfactory to the Managers, the written opinion of Vinson & Elkins L.L.P., outside counsel for CEQP, as described in Section 5(c), modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such opinion.

warranties will be true and correct as of the Time of Sale and the Settlement Date for the Units relating to such acceptance as though made at and as of each of such dates (except that such representations and warranties shall be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented relating to such Units).

(w) Prior to instructing a Manager pursuant to Section 2 hereof to make sales on any given day (or as otherwise agreed between CEQP and such Manager), CEQP GP’s board of directors (the “Board”), a duly authorized subcommittee of the Board or a duly authorized representative of the Board shall have approved the minimum price and maximum number of Units to be sold on such day.

In the event that notice of a proposed sale is provided by CEQP pursuant to this Section 6(x), such Manager may (and shall if requested by CEQP) suspend activity under this program for such period of time as may be requested by CEQP or as may be deemed appropriate by such Manager.

7. Covenant of the Managers. Each Manager severally covenants with the CEQP Parties not to take any action that would result in CEQP being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Manager that otherwise would not be required to be filed by CEQP thereunder, but for the action of such Manager.

8. Indemnity and Contribution. (a) The CEQP Parties, jointly and severally, agree to indemnify and hold harmless each Manager, its directors, managers, officers, employees and agents, each person, if any, who controls any Manager within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Manager within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any documented legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged

untrue statement of a material fact contained in the Registration Statement, the Prospectus, the Prospectus Supplement (including any Interim Prospectus Supplement), any road show as defined in Rule 433(h) under the Securities Act, or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Manager furnished to CEQP in writing by such Manager expressly for use therein, which information consists solely of the Agent Information.

(b) Each Manager agrees, severally and not jointly, to indemnify and hold harmless the CEQP Parties and the directors of the CEQP GP and each person, if any, who controls a CEQP Party within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the CEQP Parties to such Manager, but only with reference to information relating to such Manager furnished to CEQP in writing by such Manager expressly for use in the Registration Statement, the Prospectus, the Prospectus Supplement (including any Interim Prospectus Supplement), any road show, or any amendment or supplement thereto, which information consists solely of the Agent Information.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. A failure to promptly notify the person against whom such indemnity may be sought shall not relieve the indemnifying party of its obligations under this Section 8 or otherwise unless such party shall be materially prejudiced by such failure to provide prompt notice. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, (iii) such counsel has a conflict of interest or (iv) such counsel is not retained in a timely manner. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be

liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such documented fees and expenses reasonably incurred shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Managers, in the case of parties indemnified pursuant to Section 8(a), and by the CEQP Parties, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for documented fees and expenses of counsel reasonably incurred as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the CEQP Parties on the one hand and the Managers on the other hand from the offering of the Units or (ii) if the allocation provided by Section 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 8(d)(i) above but also the relative fault of the CEQP Parties on the one hand and of the Managers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the CEQP Parties on the one hand and the Managers on the other hand in connection with the offering of the Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Units (before deducting expenses) received by CEQP and the total commissions received by the Managers, bear to the aggregate purchase price of the Units. The relative fault of the CEQP Parties on the one hand and the Managers on the other

hand 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 relates to information supplied by the CEQP Parties or by the Managers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Managers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Units they have purchased hereunder, and not joint.

(e) The CEQP Parties and the Managers agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Managers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any documented legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Manager shall be required to contribute any amount in excess of the amount by which the total commission received by such Manager exceeds the amount of any damages that such Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties, agreements and other statements of the CEQP Parties contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Manager, its directors, managers, officers, employees, agents, any person controlling any Manager or any affiliate of any Manager who has, or who is alleged to have, participated in the distribution of the Units as a sales agent or by or on behalf of any of the CEQP Parties, the officers or directors of the CEQP GP or any person controlling a CEQP Party and (iii) acceptance of and payment for any of the Units.

9. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Termination. (a) CEQP shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party, except that (i) with respect to any pending sale through the Managers for

CEQP, the obligations of CEQP, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1, Section 6(k) and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each Manager shall have the right, by giving written notice as hereinafter specified, to terminate its obligations under this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) with respect to any pending sale through such Manager for CEQP, the obligations of CEQP, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1 and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect until and unless terminated pursuant to Section 10(a) or (b) above or by mutual agreement of the parties or at such time as when all of the Units eligible for sale pursuant to this Agreement have been sold; provided that any such termination by mutual agreement pursuant to this clause (c) shall in all cases be deemed to provide that Section 1, Section 6(k) and Section 8 of this Agreement shall remain in full force and effect.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Managers or CEQP, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Units, such sale shall settle in accordance with the provisions of Section 4.

11. Entire Agreement. (a) This Agreement represents the entire agreement between the CEQP Parties and each Manager with respect to the preparation of any Registration Statement, Prospectus Supplement or the Prospectus, the conduct of the offering and the sale and distribution of the Units.

(b) Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Managers, each of the CEQP Parties acknowledges and agrees that in connection with the offering of the Units: (i) the relationship between the CEQP Parties, on the one hand, and the Managers, on the other, is entirely and solely commercial, and the Managers have acted and will act at arm’s length, is not and will not be an agent of, and owes no fiduciary duties to, any of the CEQP Parties or any other person, (ii) no Manager is acting as advisor, expert or otherwise, to any of the CEQP Entities in connection with the offering, sale and distribution of the Units or any other services the Managers may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Units, (iii) the Managers owes the CEQP Parties

only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iv) the Managers may have interests that differ from those of the CEQP Parties and the Managers have no obligation to disclose, or account to the CEQP Parties for, any of such additional interests. The CEQP Parties waive to the full extent permitted by applicable law any claims they may have against the Managers arising from an alleged breach of fiduciary duty in connection with the sale and distribution of the Units.

12. Research Independence. The CEQP Parties acknowledge that the Managers’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Managers’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to CEQP and/or the offering that differ from the views of their respective investment banking divisions. The CEQP Parties hereby waive and release, to the fullest extent permitted by law, any claims that the CEQP Parties may have against the Managers with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the CEQP Parties by the Managers’ investment banking divisions. The CEQP Parties acknowledge that each Manager is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

13. Parties. This Agreement shall inure to the benefit of and be binding upon the Managers, the CEQP Parties and, to the extent provided in Section 8, the officers and directors of CEQP GP and each person who controls a CEQP Party or the Managers and any directors, managers, officers, employees and agents who control any Manager, and their respective heirs, executors, administrators, successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, corporation or other entity any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of the parties hereto and their respective successors and assigns and said controlling persons and said officers, directors, managers, officers, employees and agents, and for the benefit of no other person, corporation or other entity. No purchaser of any of the Units from the Manager shall be construed a successor or assign by reason merely of such purchase.

14. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

15. Pronouns. Whenever a pronoun of any gender or number is used herein, it shall, where appropriate, be deemed to include any other gender and number.

16. Applicable Law. This Agreement, and any claim, controversy or dispute relating to or arising out of this Agreement, shall be governed by and construed in accordance with the internal laws of the State of New York. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

Due Diligence Protocol

Set forth below are guidelines for use by CEQP and the Managers in connection with the Managers’ continuous due diligence efforts in connection with the sale and distribution of the Units pursuant to the Equity Distribution Agreement between CEQP, CEQP GP and Wells Fargo Securities, LLC, Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC and RBC Capital Markets, LLC, dated August 4, 2017 (the “Agreement”). For the avoidance of doubt, CEQP has agreed that no sales under the Agreement will be requested or made at any time CEQP is, or could be deemed to be, in possession of material non-public information with respect to CEQP. Capitalized words and phrases used herein shall have the meanings given to them in the Agreement.

On or immediately prior to each Representation Date, in addition to the documents provided pursuant to Sections 6(n)—(r) of the Agreement, the Managers expect to conduct a due diligence call with the appropriate business, financial and legal representatives of CEQP.

On the date of or promptly after CEQP’s management report becomes available for a given month (but no later than the last business day of the immediately succeeding month), the Managers expect to conduct a due diligence call with the appropriate business, financial, accounting and legal representatives of CEQP and that CEQP shall provide the certificate referred to in Section 5(b) of the Agreement.

In the event that CEQP requests a Manager to sell on any one Trading Day an amount of Units that would be equal to or greater than 15% of the average daily trading volume (calculated based on the most recent three completed Trading Days) of CEQP’s common units, such Manager expects to conduct a due diligence call with the appropriate business, financial, accounting and legal representatives of CEQP and that CEQP shall provide the certificate referred to in Section 5(b) of the Agreement.

The foregoing is an expression of current intent only, and shall not in any manner limit the Managers’ rights under the Agreement, including the Managers’ right to require such additional due diligence procedures as the Managers may reasonably request pursuant to the Agreement.

Houston, Texas 77002

Ladies and Gentlemen:

We have acted as counsel for Crestwood Equity Partners LP, a Delaware limited partnership (the “Partnership”), with respect to certain legal matters in connection with the registration by the Partnership with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of the proposed issuance and sale from time to time by the Partnership of common units representing limited partner interests in the Partnership having an aggregate offering price of up to $250,000,000 (the “Units”), pursuant to that certain Equity Distribution Agreement, dated August 4, 2017 (the “Distribution Agreement”), relating to the offering and sale of the Units by and among the Partnership, Crestwood Equity GP LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), and the several managers named therein (the “Managers”).

In rendering the opinions set forth below, we have examined and relied upon (i) the registration statement on Form S-3 (File No. 333-217062) with respect to the Units being offered by the Partnership (the “Registration Statement”), which Registration Statement was declared effective by the Commission on April 12, 2017; (ii) the prospectus dated March 31, 2017 (the “Base Prospectus”) included in the Registration Statement; (iii) the prospectus supplement dated August 4, 2017 (the “Prospectus Supplement”); (iv) the Fifth Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of April 11, 2014 (as amended, the “Partnership Agreement”); (v) the Distribution Agreement; (vi) resolutions of the Board of Directors of the General Partner dated March 26, 2017; and (vii) such other certificates, statutes and other instruments and documents as we consider appropriate for the purposes of the opinions hereafter expressed. In addition, we reviewed such questions of law as we have considered appropriate.

In connection with this opinion, we have assumed that all Units will be issued and sold in compliance with and in the manner stated in the Base Prospectus, the Prospectus Supplement and the Distribution Agreement.

Based upon the foregoing and subject to the assumptions, exceptions, limitations and qualifications set forth herein, we are of the opinion that when the Units have been issued and delivered in accordance with the terms of the Distribution Agreement and upon payment of the consideration therefor provided for therein, the Units will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”)), except as described in the Base Prospectus and the Prospectus Supplement.

RE:	Crestwood Equity Partners LP Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel for Crestwood Equity Partners LP (the “Partnership”), a Delaware limited partnership, with respect to certain legal matters in connection with the preparation of a Prospectus Supplement dated on or about the date hereof (the “Prospectus Supplement”) and the Prospectus dated March 31, 2017, (“Prospectus”) forming part Registration Statement on Form S-3, No. 333-217062 (the “Registration Statement”), to which this opinion is an exhibit. The Registration Statement relates to the registration under the Securities Act of 1933, as amended, of common units representing limited partner interests in the Partnership.

This opinion is based on various facts and assumptions, and is conditioned upon certain representations made by the Partnership as to factual matters through a certificate of an officer of the Partnership (the “Officer’s Certificate”). In addition, this opinion is based upon the factual representations of the Partnership concerning its business, properties and governing documents as set forth in the Registration Statement.

In our capacity as counsel to the Partnership, we have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and other instruments, as we have deemed necessary or appropriate for purposes of this opinion. In our examination, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures thereon, the legal capacity of natural persons executing such documents and the conformity to authentic original documents of all documents submitted to us as copies. For the purpose of our opinion, we have not made an independent investigation or audit of the facts set forth in the above-referenced documents or in the Officer’s Certificate. In addition, in rendering this opinion we have assumed the truth and accuracy of all representations and statements made to us which are qualified as to knowledge or belief, without regard to such qualification.

We hereby confirm that all statements of legal conclusions contained in the discussion in the Registration Statement under the caption “Material U.S. Federal Income Tax Consequences” as updated in the Prospectus Supplement under the caption “Material U.S. Federal Income Tax Consequences,” constitute the opinion of Vinson & Elkins L.L.P. with respect to the matters set forth therein as of the effective date of the Registration Statement, subject to the assumptions, qualifications, and limitations set forth therein. This opinion is based on various statutory provisions, regulations promulgated thereunder and interpretations thereof by the Internal Revenue Service and the courts having jurisdiction over such matters, all of which are subject to change either prospectively or retroactively. Also, any variation or difference in the facts from those set forth in the representations described above, including in the Registration Statement and the Officer’s Certificate, may affect the conclusions stated herein.
