Ladies and Gentlemen:

SemGroup Corporation, a Delaware corporation (the “Company”), confirms its agreement (this “Agreement”) with ▇▇▇▇▇ Fargo Securities, LLC, Citigroup Global Markets Inc. and SunTrust ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Inc. (each, a “Manager” and collectively, the “Managers”) as follows:

1. Description of Shares.

The Company proposes to issue and sell through or to the Managers, each acting as agent or principal, shares of its Class A Common Stock, par value $0.01 per share (“Common Stock”), having an aggregate gross sales price of up to $300,000,000 (the “Shares”) from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. The Company agrees that whenever it determines to sell Shares directly to any Manager as principal it will enter into a separate written agreement, in form and substance satisfactory to the Company and such Manager, containing the terms and conditions of such sale with such Manager (a “Terms Agreement”).

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder (the “Rules and Regulations”), with the Commission a registration statement on Form S-3 (File No. 333-210044), including a base prospectus, relating to the Shares to be issued from time to time by the Company, and which incorporates by reference documents that the Company has filed or will file with the Commission in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”).

The Company has prepared a prospectus supplement specifically relating to the Shares (the “Prospectus Supplement”) to the base prospectus included as part of such registration statement. The Company will furnish to the Managers, for use by the Managers, copies of the base prospectus included as part of such registration statement, as supplemented by the Prospectus Supplement, relating to the Shares. The “Registration Statement,” as of any time, means such registration statement as amended by any post-effective amendments thereto at such time, including the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the Securities Act and the documents and information otherwise deemed to be a part thereof as of such time pursuant to Rule 430B; provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Shares, which time shall be considered the “new effective date” of the Registration Statement with respect to the Shares within the meaning of paragraph (f)(2) of Rule 430B, including the exhibits and schedules thereto at such time, the documents and information incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the Securities Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B. Any reference to the term “Registration Statement” shall be deemed to include any Rule 462(b) Registration Statement. The base prospectus, including all documents incorporated therein by reference, included in the Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus or Prospectus Supplement have most recently been filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Commission pursuant to ▇▇▇▇▇.

2. Representations and Warranties.

The Company represents and warrants to the Managers as of the date hereof and as of each Representation Date (as defined below), as of each Applicable Time (as defined below) and as of each Settlement Date (as defined below) (in each case as if such representations and warranties were made as of such date, but modified to relate to the Registration Statement, the Prospectus and the documents incorporated by reference therein, in each case as amended or supplemented as of such date) and agree with the Managers, as follows:

After the effectiveness of any such registration statement, all references to “Registration Statement” included in this Agreement shall be deemed to include such new registration statement, including all documents incorporated by reference therein pursuant to Item 12 of Form S-3, and all references to “base prospectus” included in this Agreement shall be deemed to include the final form of prospectus, including all documents incorporated therein by reference, included in any such registration statement at the time such registration statement became effective.

The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405) and was filed not earlier than the date that is three years prior to the date hereof.

(i) Documents Incorporated by Reference. The documents incorporated by reference in the Registration Statement and the Prospectus did not, and any further documents filed and incorporated by reference therein will not, when filed with the Commission, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(j) No Issuer Free Writing Prospectus. The Company has not made and will not make any offer related to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433.

3. Sale and Delivery to the Managers; Settlement.

(a) Sale of Shares. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to issue and sell through the Managers, acting as sales agents, and each Manager agrees to use its commercially reasonable efforts to sell, as agent for the Company, the Shares on the following terms:

(1) The Shares are to be sold by one of the Managers on a daily basis or otherwise as shall be agreed to by the Company and such Manager on any day that (A) is a trading day for the NYSE (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time) (each, a “Trading Day”), (B) the Company, through any of the individuals listed as authorized representatives of the Company on Exhibit A hereto (which may be updated from time to time by a certificate from the Company to the Managers) (the “Authorized Company Representatives”) has instructed any of the individuals listed as authorized representatives of such Manager on Exhibit A hereto (which may be updated from time to time by a certificate from such Manager to the Company) (the “Authorized Manager Representatives”) by telephone (confirmed promptly by electronic mail) to make such sales, and (C) the Company has satisfied its obligations under Section 6 of this Agreement. The Company will designate (i) the maximum amount of the Shares 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 Share at which such Shares 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 Shares designated for the sale by the Company on such day. The gross sales price of the Shares sold under this Section 3(a) shall be the market price for the Company’s Common Stock sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Shares. For the avoidance of doubt, the Company shall submit instructions to sell Shares to only one Manager, if any, on any single Trading Day.

(2) The Company acknowledges and agrees that (i) there can be no assurance that any Manager will be successful in selling Shares, (ii) no Manager will incur any liability or obligation to the Company or any other person or entity if it does not sell Shares 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 Shares as required under this Agreement and (iii) no Manager shall be under any obligation to purchase Shares on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Company in writing pursuant to a Terms Agreement.

(3) Notwithstanding the foregoing, the Company, through any of the Authorized Company Representatives, may instruct the Authorized Manager Representatives by telephone (confirmed promptly by electronic mail) not to sell Shares if such sales cannot be effected at or above the price designated by the Company in any such instruction. The Company 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 Shares 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 Shares sold hereunder prior to the giving of such notice. During any such period of suspension, the Company 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 Shares pursuant to this Agreement (which recommencement shall constitute a Representation Date).

(4) Subject to the terms of a Terms Agreement, the Managers may sell Shares (i) by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415, including without limitation sales made directly on the NYSE, on any other existing trading market for the Common Stock, (ii) to or through a market maker, or (iii) directly on or through an electronic communication network, a “dark pool” or any similar market venue. Subject to the terms of a Terms Agreement, the Managers may also sell Shares 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 Shares 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 Shares sold pursuant to this Section 3(a) and payable as described in Section 3(b) below. The foregoing rate of compensation shall not apply when any Manager acts as principal, in which case the Company may sell Shares to such Manager as principal at a price mutually agreed upon at the relevant Applicable Time pursuant to a Terms Agreement.

(6) Each Manager acting as sales agent hereunder shall provide written confirmation (which may be by facsimile or electronic mail) to the Company following the close of trading on the NYSE each day in which the Shares with respect to which such Manager is acting as sales agent are sold under this Section 3(a) setting forth the number of the Shares sold on such day, the aggregate gross sales proceeds, the compensation payable by the Company to such Manager with respect to such sales and the Net Proceeds (as defined below) payable to the Company. At each Manager’s election, such compensation shall either be (i) set forth and invoiced in periodic statements from such Manager to the Company, with payment to be made by the Company promptly after its receipt thereof or (ii) deducted by the Manager from the payment of the gross sales proceeds to the Company as set forth in Section 3(b) below.

(b) Settlement of Shares. Settlement for sales of Shares 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 Company on a Settlement Date against receipt of the Shares sold (the “Net Proceeds”) will be equal to the aggregate sales price received by the Manager acting as sales agent at which such Shares were sold, after deduction for (i) such Manager’s commission, discount or other compensation for such sales payable by the Company pursuant to Section 3(a)(5) hereof, (ii) any other amounts due and payable by the Company to such Manager hereunder pursuant to Section 5 and (iii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales.

(c) Delivery of Shares. On or before each Settlement Date, the Company will, or will cause its transfer agent to, electronically transfer the Shares being sold by crediting the applicable Manager’s or its designee’s account (provided such Manager shall have given the Company 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 Company and such Manager which in all cases shall be freely tradable, transferable shares eligible for delivery through DTC. On each Settlement Date, the applicable Manager will deliver the related Net Proceeds in same day funds to an account designated by the Company on, or prior to, the Settlement Date. The Company agrees that if the Company, or its transfer agent (if applicable), defaults in its obligation to deliver Shares on a Settlement Date, the Company agrees that in addition to and in no way limiting the rights and obligations set forth in Section 7(a) hereto, it will (i) indemnify and hold the applicable Manager harmless against any loss, liability, claim, damage, or expense whatsoever (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Company or its transfer agent and (ii) pay to such Manager any commission to which it would otherwise have been entitled absent such default. If any Manager breaches this Agreement by failing to deliver Net Proceeds to the Company on any Settlement Date for the Shares delivered by the Company, the Manager will pay the Company 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 Company cause or request the offer or sale of any Shares, if after giving effect to the sale of such Shares, the aggregate offering price of the Shares 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 any subsequent Registration Statement relating to the Shares, and (ii) the amount authorized from time to time to be issued and sold under this Agreement by the Company and notified to the Managers in writing. Under no circumstances shall the Company cause or request the offer or sale of any Shares pursuant to this Agreement at a price lower than the minimum price authorized from time to time by the board of directors of the Company or a duly authorized committee thereof, and notified to the Managers in writing. Further, under no circumstances shall the aggregate offering price of Shares sold pursuant to this Agreement, including any separate underwriting or similar agreement covering principal transactions described in Section 1 of this Agreement, exceed $300,000,000.

(e) Black-out Limitations. Notwithstanding any other provision of this Agreement, the Company shall not offer or sell, or instruct any Manager to offer or sell, any Shares through such Manager as agent (and, by notice to such Manager given by telephone (confirmed promptly by facsimile or email), shall cancel any instructions for any such offer or sale of any Shares prior to the commencement of the periods referenced below), and such Manager shall not be obligated to make any such offer or sale of Shares, (i) during any period in which the Company is, or could be deemed to be, in possession of material non-public information or (ii) except as provided in Section 3(f)(i) hereof, at any time during the period commencing on the 10th business day prior to the time the Company issues a press release containing, or shall otherwise publicly announce, its earnings, revenues or other operating results for a fiscal period or periods (each, an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Company files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K (a “Filing Time”) that includes consolidated financial statements as of and for the same fiscal period or periods, as the case may be, covered by such Earnings Announcement.

(f) If the Company wishes to offer or sell Shares 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 Company 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. For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, opinion or letter of counsel or accountants’ letter pursuant to this Section 3(f) shall not relieve the Company from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including, without limitation, the obligation to deliver officers’ certificates, opinions and letters of counsel and accountants’ letters as provided in Section 4(n)-(p) hereof, and (B) this Section 3(f) shall in no way affect or limit the operation of clause (i) of Section 3(e) hereof, which shall have independent application.

4. Covenants of the Company.

The Company covenants with the Managers as follows:

supplement or filing is required by law (provided, however, that the failure of any Manager to make such objection shall not relieve the Company of any obligation or liability hereunder, or affect such Manager’s right to rely on the representations and warranties made by the Company in this Agreement), and the Company will furnish to the Managers at the time of filing thereof a copy of any document that upon filing is deemed to be incorporated by reference into the Registration Statement or Prospectus, except for those documents available via ▇▇▇▇▇; and (iii) the Company will cause each amendment or supplement to the Prospectus, other than documents incorporated by reference, to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) (without reliance on Rule 424(b)(8) under the Securities Act).

(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 Company 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 Company to any Manager to sell Shares under this Agreement is in effect, which waiver shall continue until the earlier to occur of the date the Company delivers an instruction to any Manager to sell Shares 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 Company files its annual report on Form 10-K. Notwithstanding the foregoing, if the Company subsequently decides to sell Shares following a Representation Date when the Company relied on such waiver and did not provide the Managers with a certificate under this Section 4(n), then before the Company delivers an instruction pursuant to Section 3(a) or any Manager sells any Shares, the Company 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 Shares are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Company shall cause to be furnished to the Managers a written opinion of (i) ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLP, or other counsel satisfactory to the Managers, (ii) the general counsel of the Company, or other counsel satisfactory to the Managers and (iii) Dentons ▇▇▇▇▇ ▇▇▇▇▇▇▇, S.C., 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, Exhibit D and Exhibit E, 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).

(p) Comfort Letter. On or prior to the date that the first Shares are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with

respect to which the Company is obligated to deliver a certificate in the form attached hereto as Exhibit F for which no waiver is applicable, the Company 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 PCAOB (or, with respect to any financial statements prepared in accordance with Rule 3-05 or 3-09 of Regulation S-X under the Securities Act with respect to a company that is not required to have PCAOB compliant financial statements, 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 Shares are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Company 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 written opinion or opinions of ▇▇▇▇▇ ▇▇▇▇▇ 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 Company 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 Company to facilitate the sale or resale of the Shares or (ii) sell, bid for, or purchase the Shares to be issued and sold pursuant to this Agreement, or pay anyone any compensation for soliciting purchases of the Shares to be issued and sold pursuant to this Agreement other than the Managers; provided, however, that the Company may bid for and purchase its Common Stock in accordance with Rule 10b-18 under the Exchange Act; and provided further, that no such bids or purchases shall be made by the Company during the three Trading Days before or after any sale of any Shares pursuant to this Agreement.

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

(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 necessary in order 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 Company’s reports filed with the Commission, there shall not have been any material adverse change in the general affairs, condition (financial or other), management, business, prospects, assets or results of operations of the Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business.

All filings with the Commission required by Rule 424 under the Securities Act to have been filed prior to the issuance of any instruction of the Company pursuant to Section 3(a) shall have been made within the applicable time period prescribed for such filing by Rule 424.

7. Indemnification and Contribution.

(a) The Company agrees 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 Company 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 Company 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 Company may otherwise have.

(b) Each Manager, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, officers and employees, and each person who controls the Company 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 Company 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 Company 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 Company and each such Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by such Manager on the other from the offering of the Shares; 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 Shares purchased by such Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company 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 Company 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 Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company, 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 Company 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 Company 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 Shares 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 Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Managers or controlling person, or by or on behalf of the Company, and shall survive delivery of the Shares to any Manager.

Sections 9(a), (b) or (c) above or otherwise by mutual agreement of the parties.

(e) Effectiveness of Termination. Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice by such Manager or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Shares, such Shares shall settle in accordance with the provisions of this Agreement.

(f) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof, and except that, in the case of any termination of this Agreement, Section 2, Section 7, Section 8 and Section 18 hereof shall survive such termination and remain in full force and effect.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

12. Applicable Law. This Agreement and any claim, controversy or dispute relating to or arising out of 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.

FORM OF OPINION OF ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLP

1. Each of the Company and each of the subsidiaries set forth on Schedule I (the “Subsidiaries”) is validly existing and in good standing as a corporation or other business entity under the laws of its jurisdiction of organization and is duly qualified to do business and in good standing as a foreign corporation or other business entity in each jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such qualification, except where the failure to be so qualified or in good standing, in the aggregate, could not reasonably be expected to have a Material Adverse Effect. In rendering such opinion, such counsel may state that the opinion in the first sentence of such paragraph is based solely on such counsel’s review of certificates of good standing or similar certifications received from jurisdictions listed on Annex A. Each of the Company and its Subsidiaries has all power and authority necessary to own or hold its properties and conduct the businesses in which it is engaged.

2. The Company has an authorized capitalization as set forth in the Registration Statement and the Prospectus under the heading “Description of Capital Stock.”

3. The Shares to be issued and sold by the Company under the Agreement have been duly authorized and, upon payment and delivery in accordance with the Agreement, will be validly issued, fully paid and non-assessable and free of preemptive rights arising from the Certificate of Incorporation and Bylaws of the Company (the “Governing Documents”).

4. Except as described in the Registration Statement and the Prospectus, (i) there are no options, warrants or other rights to purchase, any restrictions upon the voting or transfer of, or agreements or other obligations to issue or rights to convert any securities into or exchange any securities for Shares of the Company under any Governing Document or, to such counsel’s knowledge, any other agreement, and (ii) no Person has the right, which has not been waived, under any Governing Document or, to such counsel’s knowledge, other agreement to require the registration under the Securities Act of any sale of securities issued by the Company, by reason of the filing or effectiveness of the Registration Statement.

5. The Agreement has been duly and validly authorized, executed and delivered by the Company.

6. Subject to customary assumptions and qualifications, the execution and delivery of the Agreement and the issuance and sale of the Shares by the Company pursuant to the Agreement do not:

violate the Company’s Governing Documents; or

result in the breach of or a default under the SemGroup Credit Agreement or any of the agreements of the Company or its Subsidiaries that were identified to such counsel by an officer of the Company as being material to the Company and its Subsidiaries, taken as a whole, and listed in Exhibit A; or

violate any federal, New York or Oklahoma statute, rule or regulation, the General Corporation Law of the State of Delaware (the “DGCL”), or the court or governmental orders, writs, judgments or decrees specifically directed to the

C-1

Company that were identified to such counsel by an officer of the Company as being material to the Company and its Subsidiaries, taken as a whole, and listed in Exhibit B, applicable to the Company and its Subsidiaries; or

require any consents, approvals, or authorizations to be obtained by the Company from, or any registrations, declarations or filings to be made by the Company with, any governmental authority under any federal, New York or Oklahoma statute, rule or regulation applicable to the Company or under the DGCL that have not been obtained or made.

7. The Registration Statement is effective under the Securities Act, and the Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) under the Securities Act specified in such opinion on the date specified therein. To such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding or examination for such purpose has been instituted or threatened by the Commission.

8. The Registration Statement at the latest effective date, and the Prospectus, as of its date, each appeared on their face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-3 under the Securities Act and the rules and regulations of the Commission thereunder; it being understood, however, that such counsel expresses no view with respect to Regulation S-T or the financial statements, schedules, or other financial data, or assessments of or reports on the effectiveness of internal control over financial reporting included in, incorporated by reference in or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement and the Prospectus are correct and complete.

9. The statements made in each of the Registration Statement and the Prospectus under the caption “Description of Capital Stock,” insofar as they purport to constitute summaries of the terms of the Class A Common Stock (including the Shares), constitute accurate summaries of the terms of such Class A Common Stock in all material respects.

10. The Company is not, and after giving effect to the offer and sale of the Shares and the application of the proceeds therefrom as described under “Use of Proceeds” in the Prospectus will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

In rendering such opinion, such counsel may (i) state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the States of New York and Oklahoma and the DGCL and that such counsel is not admitted in the State of Delaware, and (ii) rely upon such certificates, assumptions, limitations and qualifications as are customary in connection with rendering such opinion.

Such counsel has reviewed the Registration Statement and the Prospectus and has participated in conferences with officers and other representatives of the Company, representatives of its independent registered public accounting firm and with the Managers’

C-2

representatives and their counsel, at which the contents of the Registration Statement, the Prospectus and related matters were discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Registration Statement or the Prospectus, and such counsel has not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement and the Prospectus involve matters of a non-legal nature. Accordingly, such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement and the Prospectus (except to the extent stated in paragraph 9 above). Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel advises the Managers that no facts came to the attention of such counsel that caused it to believe that:

(i) the Registration Statement, as of the most recent effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or

(ii) the Prospectus, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading,

except that in each case such counsel need express no comment or belief with respect to the financial statements, schedules or other financial data or assessments or reports on the effectiveness of internal control over financial reporting contained or incorporated by reference in or omitted from the Registration Statement or the Prospectus. For purposes hereof, the most recent effective date is November 8, 2016, the date on which the Prospectus was first filed with the Commission.

EXHIBIT D

FORM OF OPINION OF GENERAL COUNSEL

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

I have participated in conferences with officers and other representatives of the Company and its subsidiaries, the independent registered public accounting firm for the Company, your counsel and your representatives at which the contents of the Registration Statement and the Prospectus and related matters were discussed and, although I have not independently verified and am 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 paragraph 1 above), on the basis of the foregoing (relying with respect to factual matters to the extent I deem appropriate upon statements by officers and other representatives of the Company and its subsidiaries), I confirm to you that no facts have come to my attention that have led me to believe that (i) the Registration Statement, as of the 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 the light of the circumstances under which they were made, not misleading, it being understood that I express no opinion, statement or belief in this 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. For purposes hereof, the most recent effective date is November 8, 2016, the date on which the Prospectus was first filed with the Commission.

I express no opinion as to the laws of any jurisdiction other than 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 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 however, that such references 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.

▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLP and ▇▇▇▇▇ ▇▇▇▇▇ 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.
