Item 1.01

Entry into a Material Definitive Agreement.

Purchase Agreement

On May 11, 2015, Rose Rock Midstream, L.P. (the “Partnership”) and Rose Rock Finance Corporation (“Finance Corp.” and together with the Partnership, the “Issuers”) entered into a purchase agreement (the “Purchase Agreement”) with Wells Fargo Securities, LLC, as representative of the initial purchasers listed on Schedule I to the Purchase Agreement (collectively, the “Initial Purchasers”), related to the issuance and sale by the Issuers to the Initial Purchasers of $350,000,000 aggregate principal amount of the Issuers’ 5.625% Senior Notes due 2023 (the “Notes”). The Issuers’ obligations under the Notes are fully and unconditionally guaranteed (the “Guarantees”) on a senior unsecured basis, jointly and severally, by certain of the Partnership’s current and future restricted subsidiaries (other than Finance Corp.) (collectively, the “Guarantors” and together with the Issuers, the “Obligors”).

The Notes and the Guarantees (collectively, the “Securities”) were offered and sold in private transactions in accordance with Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The offer and sale of the Securities have not been registered under the Securities Act or applicable state securities laws, and consequently, the Securities may not be offered or sold in the United States absent registration under the Securities Act or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

The Purchase Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Obligors, on one hand, and the Initial Purchasers, on the other hand, have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, the Purchase Agreement requires the execution of a registration rights agreement relating to the Notes upon the issuance thereof.

The Partnership intends to use the net proceeds from the offering of the Securities to reduce outstanding borrowings under its revolving credit facility and for general partnership purposes.

The foregoing description of the Purchase Agreement is not complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, a copy of which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated in this Item 1.01 by reference.

Equity Distribution Agreement

On May 12, 2015, the Partnership entered into an Equity Distribution Agreement (the “Agreement”) by and among the Partnership, Rose Rock Midstream GP, LLC (the “General Partner”) and Wells Fargo Securities, LLC, Citigroup Global Markets Inc. and SunTrust Robinson Humphrey, Inc. (each, a “Manager”, and collectively, the “Managers”). Pursuant to the terms of the Agreement, the Partnership may sell from time to time through the Managers, as sales agents, the Partnership’s common units representing limited partner interests (“Common Units”) having an aggregate offering amount of up to $150,000,000 (the “Units”). Sales of the Units, if any, may be made by any method permitted by law deemed to be an “at the market” offering, including ordinary brokers’ transactions on the New York Stock Exchange, to or through a market maker or directly on or through an electronic communication network, a “dark pool” or any similar market venue, at market prices, in block transactions or as otherwise agreed upon by the Managers and the Partnership.

Under the terms of the Agreement, the Partnership may also sell the Units from time to time to any Manager as principal for its own account at a price to be agreed upon at the time of sale. Any sale of the Units to a Manager as principal would be pursuant to the terms of a separate agreement between the Partnership and such Manager.

The Units will be issued pursuant to a Registration Statement on Form S-3 (File No. 333-199600), which was declared effective by the U.S. Securities and Exchange Commission on January 21, 2015. Certain legal opinions related to the issuance of the Units are filed herewith as Exhibits 5.1 and 8.1.

The Agreement contains customary representations, warranties and agreements of the Partnership and the General Partner, and customary obligations of the parties and termination provisions. The Partnership has agreed to indemnify each Manager against certain liabilities, including liabilities under the Securities Act, or to contribute to payments such Manager may be required to make because of any of those liabilities.

Any Manager may, from time to time, engage in transactions with and perform services for the Partnership and its affiliates in the ordinary course of its business.

The foregoing description of the Agreement is not complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed as Exhibit 1.2 to this Current Report on Form 8-K and is incorporated in this Item 1.01 by reference.

The Notes will be guaranteed (the “Guarantees”) on a senior unsecured basis by each of the Guarantors (as defined below). The Notes and the Guarantees are hereinafter collectively referred to as the “Securities.” The Securities will have the benefit of a registration rights agreement (the “Registration Rights Agreement”) to be dated as of the Closing Date (as defined below), between the Issuers, the subsidiaries of the Partnership (other than the Co-Issuer) listed on the signature pages hereto (the “Guarantors”) and the Initial Purchasers, pursuant to which the Issuers and the Guarantors will agree to register the Securities under the Act subject to the terms and conditions therein specified. The Securities are to be issued under an indenture (the “Indenture”), to be dated as of the Closing Date, between the Issuers, the Guarantors and Wilmington Trust, National Association, as trustee (the “Trustee”). The term Initial Purchasers shall mean either the singular or plural as the context requires. The use of the neuter in this Agreement shall include the feminine and masculine wherever appropriate. Certain terms used herein are defined in Section 21 hereof.

In connection with the sale of the Securities, the Issuers have prepared a preliminary offering memorandum, dated May 11, 2015 (as amended or supplemented at the date

thereof, the “Preliminary Memorandum”), and a final offering memorandum, dated May 11, 2015 (as amended or supplemented at the Execution Time, the “Final Memorandum”). Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Issuers, the Guarantors and their respective subsidiaries and businesses, and the Securities. Each of the Issuers hereby confirms that it has authorized the use of the Disclosure Package, the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Any reference in this Agreement to the Disclosure Package, the Preliminary Memorandum or the Final Memorandum shall be deemed to refer to and include the documents and filings incorporated by reference therein as of the effective date of the Disclosure Package, the Preliminary Memorandum or the Final Memorandum, as applicable.

-3-

jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such qualification, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Partnership and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business (a “Material Adverse Effect”).

(k) All of the issued and outstanding equity interests of the Partnership and each of its subsidiaries (other than White Cliffs, which is addressed below) have been duly authorized and validly issued (in accordance with the bylaws or limited partnership or limited liability company agreement (collectively, the “Organizational Agreements”) or the certificate of formation or incorporation, or other similar organizational document, in each case, as in effect on the date hereof (collectively, with the Organizational Agreements, the “Organizational Documents”), as applicable, of such entity), are fully paid (in the case of an interest in a limited partnership or limited liability company, to the extent required under the Organizational Documents of such entity) 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”) or Sections 18-607 and 18-804 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”), as applicable), and, except as otherwise set forth in the Disclosure Package and the Final Memorandum, all of the issued and outstanding equity interests of the Partnership’s subsidiaries (other than White Cliffs, which is addressed below) are owned by the Partnership either directly or through wholly owned subsidiaries free and clear of any security interest, claim, lien or encumbrance (collectively, “Liens”), except for Liens arising under or in connection with that certain Credit Agreement, dated November 10, 2011, by and among the Partnership, as borrower, Wells Fargo Bank, National Association, as administrative agent, and the other parties thereto, as amended through the date of this Agreement (the “Partnership Credit Agreement”).

8. Indemnification and Contribution. (a) Each of the Issuers agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, any electronic roadshow or any Issuer Written Information, or in any amendment or supplement thereto, 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 light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum, the Final Memorandum, any electronic roadshow or any Issuer Written Information, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Issuers by or on behalf of any Initial Purchaser through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Issuers may otherwise have.

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Issuers, each of their directors, each of their officers, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Issuers by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary

-20-

Memorandum or the Final Memorandum (or in any amendment or supplement thereto), and will reimburse the Issuers and such other persons for all out-of-pocket expenses reasonably incurred by the Issuers or such other persons in connection with investigating or defending any such action or claim as such expenses are incurred. This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Issuers acknowledge that the statements set forth in the ninth and tenth paragraphs under the heading “Plan of Distribution” in the Preliminary Memorandum and the Final Memorandum constitute the only written information furnished to the Issuers by or on behalf of any Initial Purchaser for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault, culpability or failure to act by or on behalf of such indemnified party. An indemnifying party shall not be liable under this Section 8 to any indemnified party regarding any settlement or

-21-

compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld, but if settled with such consent or if there is a final judgment for the plaintiff, such indemnifying party agrees to indemnify the indemnified party in accordance with this Section 8.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuers and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Issuers and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuers on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuers and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuers on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Issuers shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuers on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Issuers and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act and each officer and director of each of the Issuers shall have the same rights to contribution as the Issuers, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated

-22-

severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Issuers. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Issuers or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Issuers prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in any securities of the Partnership or trading in securities generally on the New York Stock Exchange or the NASDAQ Global Market shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of each of the Issuers or their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Issuers or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representative, will be mailed, delivered or telefaxed to Wells Fargo Securities, LLC, 550 South Tryon Street, Charlotte, NC 28202-4200, Attention: Transaction Management, fax no. (704) 383-9165 (with such fax to be confirmed by telephone to (704) 715-0541); or, if sent to the Issuers, will be mailed, delivered or telefaxed to (918) 524-8687 and confirmed to them at Two Warren Place, 6120 S. Yale Avenue, Suite 700, Tulsa, OK 74136-4216, attention of General Counsel.

-23-

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(k) hereof, no other person will have any right or obligation hereunder. The term “successors” shall not include any subsequent purchaser of any Securities from any Initial Purchaser merely by reason of such purchase.

14. Jurisdiction. The parties hereto agree that any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby shall be instituted in any State or U.S. federal court in The City of New York and County of New York, and waive any objection which they may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submit to the exclusive jurisdiction of such courts in any suit, action or proceeding.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuers and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Waiver of Jury Trial. The Issuers hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. No Fiduciary Duty. The Issuers hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Issuers and (c) the Issuers’ engagement of the Initial Purchasers in connection with the offering of the Securities and the process leading up to such offering is as independent contractors and not in any other capacity. Furthermore, each Issuer agrees that it is solely responsible for making its own judgments in connection with such offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising such Issuer on related or other matters). The Issuers agree that they will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuers, in connection with such transaction or the process leading thereto.

19. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

No Governmental Approval, which has not been obtained or made and is not in full force and effect, is required to authorize, or is required for the execution and delivery by the Issuers and each the Guarantors of the Transaction Documents to which it is a party or the incurrence or performance of its obligations thereunder.

⁴	To include agreements filed as exhibits to RRMS’ 2014 10-K (except for RRMS credit agreement and amendments thereto) and the Bilateral LC facility.

10. The Registration Rights Agreement constitutes a valid and binding obligation of each of the Issuers and Guarantors, enforceable against each of them in accordance with its terms, under applicable laws of the State of New York.

11. Assuming (i) the accuracy of the representations and warranties of the Issuers set forth in Sections 1(c) and 1(d) of the Purchase Agreement, (ii) the due performance by the Issuers and the Initial Purchasers of the covenants and agreements set forth in the Purchase Agreement, (iii) the compliance by the Initial Purchasers with the offering and transfer procedures and the restrictions described in the Offering Memorandum, (iv) the accuracy of the representations and warranties of the Initial Purchasers set forth in Section 4(b) of the Purchase Agreement, (v) the accuracy of the representations and warranties made or deemed to be made in accordance with the Purchase Agreement and the Offering Memorandum by purchasers to whom the Initial Purchasers initially resell the Notes and (vi) that purchasers to whom the Initial Purchasers initially resell the Notes have been made aware of the information set forth in the Offering Memorandum under the caption “Transfer Restrictions,” (A) the offer, issue, sale and delivery of the Notes (and the guarantees thereof by the Guarantors) to the Initial Purchasers and the initial resale of the Notes (and the guarantees thereof by the Guarantors) by the Initial Purchasers, each in the manner contemplated by the Purchase Agreement and the Offering Memorandum, do not require registration under the Securities Act, and (B) prior to the consummation of the Exchange Offer (as defined in the Registration Rights Agreement) or the effectiveness of the Shelf Registration Statement (as defined in the Registration Rights Agreement), such offer, issue, sale and delivery of the Notes (and the guarantees thereof by the Guarantors) and such initial resale of the Notes (and the guarantees thereof by the Guarantors) do not require qualification of the Indenture under the Trust Indenture Act of 1939, as amended, provided, however, that in the case of clauses (A) and (B), we express no opinion as to any subsequent resale of any Notes (and the guarantees thereof by the Guarantors).

12. None of the Issuers or the Guarantors is or, immediately after giving effect to the issuance and sale of the Notes and the application of proceeds therefrom as described in the Disclosure Package and the Offering Memorandum, will be, an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.

13. Statements under the caption “Exchange Offer; Registration Rights” and “Description of Other Indebtedness—Bilateral Letter of Credit Facility” in the Preliminary Offering Memorandum and in the Offering Memorandum, insofar as such statements purport to summarize certain provisions of documents and legal matters referred to therein and reviewed by us as described above, fairly summarize such provisions and legal matters in all material respects, subject to the qualifications and assumptions stated therein.

In addition, we have participated in conferences with officers and other representatives of the Issuers and the Guarantors, the independent registered public accounting firm for the Issuers and the Guarantors, counsel for the Initial Purchasers and representatives of the Initial Purchasers at which the contents of the Disclosure Package and the Offering Memorandum and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Disclosure Package and the Offering Memorandum (except as and to the extent set forth in paragraphs 9 and 13 above), on the basis of the foregoing (relying with

respect to factual matters to the extent we deem appropriate upon statements by officers and other representatives of the Issuers and the Guarantors), no facts have come to our attention that have led us to believe that (i) the Disclosure Package, as of 3:00 p.m. (Eastern Time) on May 11, 2015 (which you have informed us is a time prior to the time of the first sale of the Notes by the Initial Purchasers), contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (ii) the Offering Memorandum, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that we express no opinion, statement or belief in this letter with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditors’ reports thereon and (ii) any other financial or accounting data, included or incorporated by reference in, or excluded from, the Disclosure Package and the Offering Memorandum.

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) applicable laws of the United States of America, (iii) certain other specified laws of the United States of America to the extent referred to specifically herein, (iv) the General Corporation Law of the State of Delaware, (v) the Delaware Limited Liability Company Act and (vi) the Delaware Revised Uniform Limited Partnership Act. References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those appearing in paragraphs 7 and 8 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust laws, rules or regulations.

EXHIBIT A-2

Form of Opinion of Gibson Dunn & Crutcher LLP

2. When the Notes and the Guarantees endorsed thereon have been duly executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, the Notes and the Guarantee of each Guarantor endorsed thereon will be legal, valid and binding obligations of the Issuers and each such Guarantor, respectively, enforceable against them in accordance with their terms.

3. The execution and delivery by each of the Issuers and each of the Guarantors of the Closing Date Note Documents to which they are a party, the performance of their obligations thereunder, and the issuance by the Issuers and the Guarantors of the Notes and the Guarantees to the Initial Purchasers, do not and will not (A) result in a breach of or default under or (B) result in or require the creation or imposition of any lien or encumbrance upon any assets of such obligor under any agreement listed on Annex B.

4. Insofar as the statements in the Offering Memorandum under the caption “Description of the Notes” purport to describe specific provisions of the Notes or the other Closing Date Note Documents, such statements present in all material respects an accurate summary of such provisions.

5. To the extent that the statements in the Offering Memorandum under the caption “Description of Other Indebtedness—Revolving Credit Facility” purport to describe specific provisions of the Revolving Credit Facility (as defined on Annex B), such statements present in all material respects an accurate summary of such provisions.

EXHIBIT A-3

2. Each of the Oklahoma Guarantors has the limited liability company power and authority under the laws of the State of Oklahoma to (i) execute and deliver, and incur and perform all of its obligations under the Purchase Agreement, the Registration Rights Agreement and the Indenture and (ii) carry on its business and own its properties as described in the Disclosure Package and the Final Memorandum.

3. All of the issued and outstanding equity interests of each of the Oklahoma Guarantors have been duly authorized and validly issued in accordance with the respective Organizational Documents of each such Oklahoma Guarantor, are fully paid (to the extent required under the Organizational Documents of such entity) and nonassessable (except as such nonassessability may be affected by Sections 18-2031 and 18-2040(B) of the Oklahoma Limited Liability Company Act).

4. Each of the Purchase Agreement, the Registration Rights Agreement and the Indenture has been duly authorized, executed and delivered by each of the Oklahoma Guarantors.

5.

6. No Governmental Approval, which has not been obtained or made and is not in full force and effect, is required to authorize, or is required for the execution and delivery by the Oklahoma Guarantors of the Purchase Agreement, the Registration Rights Agreement or the Indenture or the incurrence or performance of their respective obligations thereunder. As used in this paragraph, “Governmental Approval” means any consent, approval, license, authorization or validation of, or filing, recording or registration with, any executive, legislative, judicial, administrative or regulatory body of the State of Oklahoma.

7.

The Partnership will designate (i) the maximum amount of the Units to be sold by such Manager daily as agreed to by such Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and (ii) the minimum price per Unit at which such Units may be sold. Subject to the terms and conditions hereof, such Manager shall use its commercially reasonable efforts to sell on a particular day all of the Units designated for the sale by the Partnership on such day. The gross sales price of the Units sold under this Section 3(a) shall be the market price for the Partnership’s Common Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Units. For the avoidance of doubt, the Partnership shall submit instructions to sell Units to only one Manager, if any, on any single Trading Day.

(2) The Partnership acknowledges and agrees that (i) there can be no assurance that any Manager will be successful in selling Units, (ii) no Manager will incur any liability or obligation to the Partnership 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 to sell such Units as required under this Agreement and (iii) no Manager shall be under any obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Partnership in writing pursuant to a Terms Agreement.

(3) The Partnership or any Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend or terminate the offering

of the Units with respect to which such Manager is acting as sales agent for any reason and at any time; 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, the Partnership shall not be obligated to deliver (or cause to be delivered) any of the documents referred to in Sections 4(n)–(p), be deemed to affirm any of the representations or warranties contained in this Agreement, or be obligated to conduct any due diligence session as referred to in Section 4(l) 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.

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.

(5) The compensation to each Manager for sales of the Units with respect to which such Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Units sold pursuant to this Section 3(a) and payable as described in Section 3(b) below.

At each Manager’s election, such compensation shall either be (i) set forth and invoiced in periodic statements from such Manager to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof or (ii) deducted by the Manager from the payment of the gross sales proceeds to the Partnership as set forth in Section 3(b) below.

(b) Settlement of Units. Settlement for sales of Units pursuant to Section 3(a) will occur on the third Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made (each, a “Settlement Date”). The amount of proceeds to be delivered to the Partnership on a Settlement Date against receipt of the Units sold (the “Net Proceeds”) will be equal to the aggregate sales price received by the Manager acting as sales agent at which such Units were sold, after deduction for (i) such Manager’s commission, discount or other compensation for such sales payable by the

Partnership pursuant to Section 3(a)(5) hereof, unless such Manager has elected to invoice the Partnership for such commission, discount or other compensation pursuant to Section 3(a)(6), and (ii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales.

(c) Delivery of Units. On or before each Settlement Date, the Partnership will, or will cause its transfer agent to, electronically transfer the Units being sold by crediting the applicable Manager’s or its designee’s account (provided such Manager shall have given the Partnership written notice of such designee prior to the Settlement Date) at The Depository Trust Company (“DTC”) through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the Partnership and such Manager which in all cases shall be freely tradable, transferable units eligible for delivery through DTC.

If any Manager breaches this Agreement by failing to deliver Net Proceeds to the Partnership on any Settlement Date for the Units delivered by the Partnership, the Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to such Manager.

(d) Limitations on Offering Size. Under no circumstances shall the Partnership cause or request the offer or sale of any Units, if after giving effect to the sale of such Units, the aggregate offering price of the Units sold pursuant to this Agreement would exceed the lesser of (i) the amount available for offer and sale under the currently effective Registration Statement, and (ii) the amount authorized from time to time to be issued and sold under this Agreement by the Partnership and notified to the Managers in writing.

(f) If the Partnership wishes to offer or sell Units to any Manager as agent at any time during the period from and including an Earnings Announcement through and including the time that is 24 hours after the corresponding Filing Time, the Partnership shall first (i) prepare and deliver to such Manager (with a copy to counsel to such Manager) a Current Report on Form 8-K that includes substantially the same financial and related information (together with management’s discussion and analysis thereof) that was included in such Earnings Announcement (other than any earnings projections and similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to such Manager, and, prior to its filing, obtain the written consent of such Manager to such filing (which consent shall not be unreasonably withheld), (ii) provide such Manager with the officers’ certificate, opinions and letters of counsel and accountants’ letter specified in Section 4(n)-(p) hereof, (iii) afford such Manager the opportunity to conduct a due diligence review in accordance with Section 4(l) hereof prior to filing such Earnings 8-K and (iv) file such Earnings 8-K with the Commission, then the provision of clause (ii) of Section 3(e) shall not be applicable for the period from and after the time at which the foregoing conditions shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the time that is 24 hours after the Filing Time of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be.

The Partnership will furnish to the Managers and their counsel (at the expense of the Partnership) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein, except for those documents available via EDGAR) and all amendments and supplements to the Registration Statement or Prospectus, other than documents incorporated by reference, that are filed with the Commission during any period in which a Prospectus relating to the Units is required to be delivered under the Securities Act (including, if requested, all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities and at such locations as the Managers may from time to time reasonably request. The copies of the Registration Statement and the Prospectus and any supplements or amendments thereto furnished to the Managers will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(d) Continued Compliance with Securities Laws. If at any time when a Prospectus is required by the Securities Act or the Exchange Act to be delivered in connection with a pending

sale of the Units (including, without limitation, pursuant to Rule 172), any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Managers or for the Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the Securities Act, the Partnership will promptly notify the applicable Manager to suspend the offering of Units during such period and the Partnership will use its commercially reasonable efforts promptly to prepare and file with the Commission such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Partnership will furnish to the Managers such number of copies of such amendment or supplement as the Managers may reasonably request.

(e) Blue Sky and Other Qualifications. The Partnership will, if necessary for the qualification of the Units for sale under the laws of such jurisdictions as any Manager may designate, furnish such information as may be required and otherwise cooperate in qualifying the Units for offering and sale under the securities or blue sky laws of such states or other jurisdictions as any Manager may designate and will maintain such qualifications in effect so long as required for the distribution of the Units and will pay any fee of FINRA in connection with its review of the offering; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Units, in any jurisdiction where it is not now so subject.

(f) Rule 158. The Partnership will make generally available to its unitholders as soon as practicable an earnings statement for the purposes of, and to provide to the Managers the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act.

(h) Listing. The Partnership will use its commercially reasonable efforts to cause the Units to be listed on the NYSE.

(i) Reporting Requirements. The Partnership, during any period when the Prospectus is required to be delivered under the Securities Act and the Exchange Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(j) Notice of Other Sales. At any time that sales of the Units have been made but not settled or at any time the Partnership has outstanding with any Manager any instructions to sell the Units but such instructions have not been fulfilled or cancelled, the Partnership will not, without (i) giving the Managers at least three business days’ prior written notice specifying the

nature of the proposed sale and the date of such proposed sale and (ii) the Managers suspending activity under this program for such period of time as requested by the Partnership or as deemed appropriate by the Managers in light of the proposed sale, (A) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, lend or otherwise transfer or dispose of, directly or indirectly, any Common Units or securities convertible into or exchangeable or exercisable for or repayable with Common Units, or file any registration statement under the Securities Act with respect to any of the foregoing (other than a shelf registration statement under Rule 415 under the Securities Act, a registration statement on Form S-8 or post-effective amendment to the Registration Statement) or (B) enter into any swap or other agreement or any transaction that transfers in whole or in part, directly or indirectly, any of the economic consequence of ownership of the Common Units, or any securities convertible into or exchangeable or exercisable for or repayable with Common Units, whether any such swap or transaction described in clause (A) or (B) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (x) the Common Units to be offered and sold through any Manager pursuant to this Agreement and (y) equity incentive awards approved by the Board of Directors or the compensation committee thereof or the issuance of Common Units upon vesting thereof or (z) the issuance of any Common Units in connection with any acquisition, provided, that in connection with such issuance, the seller(s) agrees in writing to be bound by the provisions of this Section 4(j).

(k) Change of Circumstances. The Partnership will, at any time during a fiscal quarter in which the Partnership intends to instruct any Manager to sell Units under this Agreement, advise the Managers promptly after it shall have received notice or obtained knowledge thereof, of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or other document provided to the Managers pursuant to this Agreement.

(l) Due Diligence Cooperation. The Partnership will cooperate with any reasonable due diligence review conducted by the Managers or their agents in connection with the transactions contemplated hereby, including, without limitation, providing information and making available documents and senior officers, during regular business hours and at the Partnership’s principal offices, as the Managers may reasonably request.

(m) Disclosure of Sales. The Partnership will disclose in its quarterly reports on Form 10-Q and in its annual report on Form 10-K the number of Units sold through the Managers, the Net Proceeds to the Partnership and the compensation payable by the Partnership to the Managers with respect to such Units.

(n) Representation Dates; Certificate. On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and:

(1) each time the Partnership:

(i) files the Prospectus relating to the Units or amends or supplements the Registration Statement or the Prospectus relating to the Units by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of documents by reference into the Registration Statement or the Prospectus relating to the Units;

(ii) files an annual report on Form 10-K under the Exchange Act;

(iii) files a quarterly report on Form 10-Q under the Exchange Act; or

(2) at any time the Units are delivered to any Manager as principal pursuant to a Terms Agreement; and

(3) at any other time reasonably requested by the Managers (each such date of filing of one or more of the documents referred to in clauses (1)(i) through (iv) and any time of request pursuant to this Section 4(n) shall be a “Representation Date”),

the Partnership shall furnish the Managers (or in the case of clause (2) above, the relevant Manager party to such Terms Agreement) with a certificate, in the form attached hereto as Exhibit F within three Trading Days of any Representation Date. The requirement to provide a certificate under this Section 4(n) shall be waived for any Representation Date occurring at a time at which no instruction by the Partnership to any Manager to sell Units under this Agreement is in effect, which waiver shall continue until the earlier to occur of the date the Partnership delivers an instruction to any Manager to sell Units pursuant to Section 3(a) hereof (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date; provided, however, that such waiver shall not apply for any Representation Date on which the Partnership files its annual report on Form 10-K. Notwithstanding the foregoing, if the Partnership subsequently decides to sell Units following a Representation Date when the Partnership relied on such waiver and did not provide the Managers with a certificate under this Section 4(n), then before the Partnership delivers an instruction pursuant to Section 3(a) or any Manager sells any Units, the Partnership shall provide such Manager with a certificate, in the form attached hereto as Exhibit F, dated the date of such instruction.

(o) Legal Opinions. On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Partnership shall cause to be furnished to the Managers a written opinion of (i) Andrews Kurth LLP (“Partnership Counsel”), or other counsel satisfactory to the Managers and (ii) the general counsel of the General Partner, or other counsel satisfactory to the Managers, each in form and substance satisfactory to the Managers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit C and Exhibit D, respectively, modified, as necessary, to relate to the Registration Statement and the Prospectus as then amended or supplemented; provided, however, that in lieu of such opinions for subsequent Representation Dates, counsel may furnish the Managers with a letter (a “Reliance Letter”) to the effect that the Managers may rely on a prior

opinion delivered under this Section 4(o) to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented at such Representation Date). On each Representation Date described in Section 4(n)(1)(ii) or 4(n)(3) and within three Trading Days of the first Representation Date following any amendment or restatement of the Partnership Agreement or the General Partner LLC Agreement with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Partnership shall cause to be furnished to the Managers a written opinion of Richards, Layton and Finger, P.A., or such other counsel satisfactory to the Managers, in form and substance satisfactory to the Managers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit E; provided, however, that in lieu of such opinion for subsequent Representation Dates, counsel may furnish the Managers with a Reliance Letter.

(p) Comfort Letter. On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Partnership shall cause BDO USA, LLP (and any other independent accountants whose report is included in the Registration Statement or the Prospectus) to furnish the Managers a letter or letters (the “Comfort Letters”) with respect to each of the entities for which financial statements are included or incorporated by reference in the Registration Statement, dated the date the Comfort Letter is delivered, in form and substance satisfactory to the Managers, each (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act, the Exchange Act and the Public Company Accounting Oversight Board (or, with respect to any financial statements prepared in accordance with Rule 3-05 of Regulation S-X under the Securities Act, the American Institute of Certified Public Accountants), (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and (iii) updating the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

(q) Opinion of Counsel for the Managers. On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Managers shall have received the favorable written opinion or opinions of Baker Botts L.L.P., counsel for the Managers, dated such date, with respect to such matters as the Managers may reasonably request.

(r) Market Activities. The Partnership will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units or (ii) sell, bid for, or purchase the Units to be issued and sold pursuant to this Agreement, or pay anyone any compensation for soliciting purchases of the Units to be issued and sold pursuant to this Agreement other than the Managers; provided,

however, that the Partnership may bid for and purchase its Common Units in accordance with Rule 10b-18 under the Exchange Act; and provided further, that no such bids or purchases shall be made by the Partnership during the three Trading Days before or after any sale of any Units pursuant to this Agreement.

(s) No Offer to Sell. The Partnership will not, directly or indirectly, make, use, prepare, authorize, approve or refer to any free writing prospectus relating to the Units to be sold by the Managers as principal or agent hereunder.

The respective obligations of the Managers hereunder with respect to a sale of Units will be subject to the continuing accuracy and completeness of the representations and warranties of

the Partnership Parties contained in this Agreement or in certificates of any officer of the Partnership Parties delivered pursuant to the provisions hereof, to the performance by the Partnership Parties of its covenants and other obligations hereunder, and to the following further conditions:

(a) Effectiveness of Registration Statement.

(b) No Material Notices. None of the following events shall have occurred and be continuing: (i) the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus, or any material document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, related Prospectus, or such incorporated documents so that, in the case of the Registration Statement, it will not contain any materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, that in the case of the Prospectus, it will not contain any materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(c) Material Changes. Except as contemplated in the Prospectus, or disclosed in the Partnership’s reports filed with the Commission, there shall not have been any material adverse change in or affecting the condition (financial or otherwise), results of operations, partners’ capital, properties, management, business or prospects of the Partnership Entities taken as a whole.

7. Indemnification and Contribution.

(a) The Partnership Parties agree, jointly and severally, to indemnify and hold harmless each Manager, its affiliates, directors, officers, employees and agents, and each person who controls any Manager within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, (ii) the omission or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) the omission or alleged omission to state in any Prospectus or any Issuer Free Writing Prospectus a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership Parties will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership Parties by or on behalf of the Managers specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of the Managers consists of the information described as such in Section 7(b) hereof. This indemnity agreement will be in addition to any liability which the Partnership Parties may otherwise have.

(b) Each Manager, severally and not jointly, agrees to indemnify and hold harmless the Partnership Parties, their directors, each of their officers and employees, and each person who controls the Partnership Parties within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to such Manager, but only with reference to any written information furnished to the Partnership Parties by or on behalf of the Managers specifically for inclusion in the Registration Statement and the Prospectus, it being understood and agreed that the only such information furnished by or on behalf of the Managers

for inclusion in the Registration Statement and the Prospectus consists of the name of each Manager. This indemnity agreement will be in addition to any liability which each Manager may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) 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) In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership Parties and each Manager, severally and not jointly, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Partnership Parties and each such Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties on the one hand and by such Manager on the other from the offering of the Units; provided, however, that in no case

shall any Manager be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership Parties and each Manager, severally and not jointly, shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership Parties on the one hand and of such Manager on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Partnership Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Partnership Parties, and benefits received by such Manager shall be deemed to be equal to the total commissions received by such Manager. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership Parties on the one hand or such Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Partnership Parties and the Managers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 7(d), no Manager shall be required to contribute any amount in excess of the amount by which the total price at which the Units purchased by it and distributed to the public exceeds the amount of any damages which such Manager has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 7, each person who controls any Manager within the meaning of either the Securities Act or the Exchange Act and each affiliate, director, officer, employee and agent of any Manager shall have the same rights to contribution as the Managers, and each person who controls the Partnership Parties within the meaning of either the Securities Act or the Exchange Act, each officer of the Partnership Parties who shall have signed the Registration Statement and each director of the Partnership Parties shall have the same rights to contribution as the Partnership Parties, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Representations, Warranties and Agreements to Survive Delivery.

If such termination shall occur prior to the Settlement Date for any sale of Units, such Units shall settle in accordance with the provisions of this Agreement.

(f) Liabilities.

Furthermore, the Partnership agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any Manager has advised or is currently advising the Partnership on related or other matters). The Partnership Parties agree that they will not claim that any Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Partnership Parties, in connection with such transaction or the process leading thereto.

As used in this paragraph, “Governmental Approval or Filing” means any consent, approval, license, authorization or validation of, or filing, recording or registration with, any executive, legislative, judicial, administrative or regulatory body of the State of New York, the State of Delaware or the United States of America, pursuant to (i) applicable laws of the State of New York, (ii) the DGCL, (iii) the Delaware LP Act, (iv) the Delaware LLC Act or (v) applicable laws of the United States of America.

12. The statements in the Registration Statement and the Prospectus under the captions “Provisions of Our Partnership Agreement Relating to Cash Distributions,” “Description of the Common Units,” “The Partnership Agreement” and “Investment in Rose Rock Midstream, L.P. by Employee Benefit Plans,” insofar as such statements purport to summarize certain provisions

C-2

of documents and legal matters referred to therein and reviewed by us as described above, fairly summarize such provisions and legal matters in all material respects, subject to the qualifications and assumptions stated therein.

13. The Units conform in all material respects to the descriptions thereof contained in the Registration Statement and the Prospectus.

14. Our opinion that is filed as Exhibit 8.1 to the Form 8-K filed on [●], is confirmed, and the Managers may rely upon such opinion as if it were addressed to them.

15. None of the Partnership Entities is, and immediately after giving effect to the issuance and sale of the Units and the application of the proceeds therefrom as described in the Registration Statement and the Prospectus under the caption “Use of Proceeds” none of them will be, an “investment company” within the meaning of such term as used in the Investment Company Act of 1940, as amended.

In addition, such counsel shall that it has participated in conferences with officers and other representatives of the Partnership Entities, the independent registered public accounting firm for the Partnership, counsel to the Managers and their representatives at which the contents of the Registration Statement and the Prospectus and related matters were discussed and, although such counsel has not independently verified and is not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus (except as and to the extent set forth in paragraphs 12 and 13 of such counsel’s opinion), on the basis of the foregoing (relying with respect to factual matters to the extent it deems appropriate upon statements by officers and other representatives of the Partnership Entities), (a) such counsel shall confirm that, in its opinion, each of the Registration Statement, as of its most recent effective date, and the Prospectus, as of its date, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations (except that we express no statement or belief as to Regulation S-T), (b) such counsel has not become aware of any documents that are required to be filed as exhibits to the Registration Statement and are not so filed or of any documents that are required to be summarized in the Prospectus and are not so summarized and (c) furthermore, no facts have come to such counsel’s attention that have led it to believe that (i) the Registration Statement, as of its most recent effective date, contained an untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) the Prospectus, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that such counsel need express no opinion, statement or belief in its letter with respect to (i) the historical and pro forma financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, (ii) any other financial or accounting data, included in, or excluded from, the Registration Statement or the Prospectus and (iii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement.

Furthermore, such counsel shall advise that a notice filed by the SEC on its Electronic Data Gathering, Analysis and Retrieval system states that the Registration Statement was

C-3

declared effective under the Securities Act on January 21, 2015. In addition, based solely on such counsel’s review of the information made available by the SEC at http://www.sec.gov/litigation/stoporders.shtml, such counsel shall confirm that the SEC has not issued any stop order suspending the effectiveness of the Registration Statement. To such counsel’s knowledge, based solely on its participation in the conferences mentioned above regarding the Registration Statement, no proceedings for that purpose are pending or have been instituted or threatened by the SEC.

Such counsel need express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) the DGCL, (iii) the Delaware LP Act, (iv) the Delaware LLC Act, (v) applicable laws of the United States of America and (vi) certain other specified laws of the United States of America to the extent referred to specifically in such counsel’s opinion. References in such opinion to “applicable laws” mean those laws, rules and regulations that, in such counsel’s experience, are normally applicable to transactions of the type contemplated by the Equity Distribution Agreement, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those appearing in paragraphs 10 and 11 of such counsel’s opinion) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust laws, rules or regulations.

C-4

EXHIBIT D

FORM OF OPINION OF GENERAL COUNSEL

1. None of (a) the offering, issuance or sale of the Units by the Partnership, (b) the execution, delivery and performance of this Agreement by the Partnership Entities party hereto, (c) the consummation of the transactions contemplated by this Agreement by the Partnership Entities or (d) the application of the proceeds from the sale of the Units by the Partnership as described under “Use of Proceeds” in the Prospectus violates or will violate any order, judgment, decree or injunction known to such counsel of any court or governmental agency or body directed to any of the Partnership Entities or any of their properties in a proceeding to which any of them or their property is a party or is bound.

2. To the knowledge of such counsel, there are no legal or governmental proceedings pending or threatened to which any Partnership Entity is a party or to which any property of any Partnership Entity or any of its affiliates is subject that are required to be described in the Registration Statement or the Prospectus but are not so described as required by the Act.

3. Wattenberg Holding, LLC has the power and authority under the laws of the State of Oklahoma to carry on its business and own or lease its properties as described in the Registration Statement and the Prospectus.

I express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of Oklahoma. References herein to “applicable laws” mean those laws, rules and regulations that, in my experience, are normally applicable to transactions of the type contemplated by the Equity Distribution Agreement, without my having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided,

D-1

however, that such references (including without limitation those appearing in paragraph 1 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust laws, rules or regulations.

Andrews Kurth LLP and Baker Botts L.L.P. are each authorized to rely upon this opinion letter in connection with the offering as if such opinion letter were addressed and delivered to them on the date hereof; provided, that this opinion letter may be relied upon by the Managers and their counsel only in connection with the offering and no other use or distribution of this opinion letter may be made without my prior written consent.

In connection therewith, we have participated in the preparation of the discussion set forth in the Registration Statement under the caption “Material Federal Income Tax Consequences,” as modified by the statements in the Prospectus Supplement under the caption “Material Tax Considerations” (the “Discussion”).

The statements in the Discussion, insofar as such statements purport to constitute summaries of United States federal income tax law and regulations or legal conclusions with respect thereto, subject to the qualifications and assumptions stated therein and the limitations and qualifications set forth herein, constitute our opinion as to the material United States federal income tax consequences for purchasers of the Units pursuant to the Offering.

This opinion letter is limited to the matters set forth herein, and no opinions are intended to be implied or may be inferred beyond those expressly stated herein. Our opinion is rendered as of the date hereof and we assume no obligation to update or supplement this opinion or any matter related to this opinion to reflect any change of fact, circumstances, or law after the date hereof. In addition, our opinion is based on the assumption that the matter will be properly presented to the applicable court.

Furthermore, our opinion is not binding on the Internal Revenue Service or a court. In addition, we must note that our opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. There can be no assurance that the Internal Revenue Service will not take a contrary position or that a court would agree with our opinion if litigated.

We hereby consent to the filing of this opinion as an exhibit to the Current Report on Form 8-K of the Partnership and to the references to our firm and this opinion contained in the Discussion. In giving this consent, we do not admit that we are included in the category of persons whose consent is required under Section 7 of the Act or under the rules and regulations of the SEC relating thereto, with respect to any part of the Registration Statement, including this exhibit to the Current Report on Form 8-K.
