The Purchaser agrees to indemnify AMID, the General Partner and their respective Representatives (collectively, “AMID Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, promptly upon demand, to pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Purchaser contained herein, provided that such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties; and provided further, that no AMID Related Party shall be entitled to recover special, consequential (including lost profits or diminution in value) or punitive damages.

Section 6.3 Indemnification Procedure. Promptly after any AMID Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any

indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Section 7.1 Interpretation and Survival of Provisions. Article, Section and Exhibit references are to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any party has an obligation under the Operative Documents, the expense of complying with that obligation shall be an expense of such party unless otherwise specified. Whenever any determination, consent, or approval is to be made or given by the Purchaser, such action shall be in the Purchaser’s sole discretion unless otherwise specified in this Agreement. If any provision in the Operative Documents is held to be illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and the Operative Documents shall be construed and enforced as if such illegal, invalid, not binding, or unenforceable provision had never comprised a part of the Operative Documents, and the remaining provisions shall remain in full force and effect. The Operative Documents have been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter.

Section 7.2 Survival of Provisions. The representations and warranties set forth in Sections 3.1, 3.2, 3.5, 3.9, 3.10, 3.15, 4.1, 4.2, 4.5, 4.6 and 4.7 hereunder shall survive the execution and delivery of this Agreement indefinitely, and the other representations and warranties set forth herein shall survive for a period of twelve months following the Closing Date regardless of any investigation made by or on behalf of AMID or the Purchaser. The covenants made in this Agreement or any other Operative Document shall survive the Closing of the transactions described herein and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and the Warrant and payment therefor and repayment, conversion, exercise or repurchase thereof.

(a) Delay. No failure or delay on the part of any party in exercising any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power, or remedy preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification, or termination of any provision of this Agreement or any other Operative Document (except in the case of the Partnership Agreement, for amendments adopted pursuant to the terms thereof) shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification, or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Operative Document, any waiver of any provision of this Agreement or any other Operative Document, and any consent to any departure by AMID from the terms of any provision of this Agreement or any other Operative Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on a party hereto in any case shall entitle such party to any other or further notice or demand in similar or other circumstances.

(a) Binding Effect. This Agreement shall be binding upon AMID, the Purchaser, and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

(b) Assignment of Rights. All or any portion of the rights and obligations of the Purchaser under this Agreement may be transferred by the Purchaser to any Affiliate of the Purchaser without the consent of AMID. No portion of the rights and obligations of the Purchaser under this Agreement may be transferred by the Purchaser to a non-Affiliate without the written consent of AMID (which consent shall not be unreasonably withheld by AMID).

Section 7.5 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by registered or certified mail, return receipt requested, telecopy, air courier guaranteeing overnight delivery or personal delivery to the following addresses:

or to such other address as AMID or the Purchaser may designate in writing. All notices and communications shall be deemed to have been duly given: (i) at the time delivered by hand, if personally delivered; (ii) if sent via electronic mail, upon the sender’s receipt of an acknowledgment from the intended recipient (such as by the “read receipt requested” function, if applicable, return e-mail or other written acknowledgment) excluding “out of office” and similar automatic replies; (iii) upon actual receipt if sent by certified mail, return receipt requested, or regular mail, if mailed; (iv) when receipt acknowledged, if sent via facsimile (except, that, if not given during normal business hours for the recipient, such notice shall be deemed to have been given at the opening of business on the next Business Day for the recipient); and (v) upon actual receipt when delivered to an air courier guaranteeing overnight delivery.

Section 7.6 Removal of Legend. In connection with a sale of any Securities by the Purchaser in reliance on Rule 144, the Purchaser or its broker shall deliver to the transfer agent and AMID a broker representation letter providing to the transfer agent and AMID any information AMID deems necessary to determine that the sale of such Securities is made in compliance with Rule 144, including a certification that the Purchaser is not an Affiliate of AMID and regarding the length of time such Securities have been held. Upon receipt of such representation letter, AMID shall promptly direct its transfer agent to exchange unit certificates bearing a restrictive legend for unit certificates without the legend (or a credit for such units to book-entry accounts maintained by the transfer agent), including the legend referred to in Section 4.8, and AMID shall bear all costs associated therewith. After the Purchaser or its permitted assigns have held the Securities for one year, if the certificate for such Purchased Units still bears the restrictive legend referred to in Section 4.8, AMID agrees, upon request of the Purchaser or permitted assignee, to take all steps necessary to promptly effect the removal of the legend described in Section 4.8 from the Securities, and AMID shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as the Purchaser or its permitted assigns provide to AMID any

information AMID deems necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including a certification that the holder is not an Affiliate of AMID (and a covenant to inform AMID if it should thereafter become an Affiliate and to consent to exchange its certificates for certificates bearing an appropriate restrictive legend) and regarding the length of time the Securities have been held.

Section 7.7 Entire Agreement. This Agreement, the other Operative Documents and the other agreements and documents referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or the other Operative Documents with respect to the rights granted by AMID or any of its Affiliates or the Purchaser or any of its Affiliates set forth herein or therein. This Agreement, the other Operative Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 7.8 Governing Law. This Agreement will be construed in accordance with and governed by the laws of the State of New York.

Section 7.9 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

Section 7.10 Recapitalization, Exchanges, Etc. Affecting the Securities. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all equity interests of AMID or any successor or assign of AMID (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Securities, and shall be appropriately adjusted for combinations, recapitalizations and the like occurring after the date of this Agreement and prior to the Closing.

IN WITNESS WHEREOF, the parties hereto execute this Agreement, effective as of the date first above written.

THIS WARRANT HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE (THE “STATE LAWS”). THIS WARRANT MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED OR OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, IN THE ABSENCE OF SUCH REGISTRATION OR QUALIFICATION OR THE AVAILABILITY OF AN APPLICABLE EXEMPTION FROM THE REGISTRATION AND QUALIFICATION REQUIREMENTS OF SUCH ACT AND STATE LAWS EVIDENCED BY AN OPINION OF LEGAL COUNSEL, WHICH OPINION AND LEGAL COUNSEL ARE SATISFACTORY TO THE PARTNERSHIP.

This Warrant certifies that, for value received, Magnolia Infrastructure Holdings, LLC, or its registered assigns (collectively, the “Holder”), is entitled to purchase from American Midstream Partners, LP, a Delaware limited partnership (the “Partnership”), up to 700,000 common units representing limited partner interests in the Partnership (the “Common Units”), subject to adjustment as set forth herein, for an exercise price of $22.00 per Common Unit (the “Exercise Price”). This Warrant shall be exercisable after the date hereof and on or before the seventh anniversary of the date hereof (the “Exercise Period”).

As used herein, the term “Warrant Exercised Units” refers to the Common Units issuable upon exercise of this Warrant. Terms used but not defined in this Warrant are defined in the Fifth Amended and Restated Agreement of Limited Partnership of the Partnership dated April 25, 2016, as amended (the “Fifth A/R Partnership Agreement”).

This Warrant, together with all warrants issued upon transfer, exchange or in replacement hereof pursuant to Section 4 (collectively, the “Warrants”), is subject to the following additional terms, provisions and conditions:

Section 1. Manner of Exercise; Issuance of Certificates; Payment for Warrant Exercised Units. Subject to the provisions hereof, this Warrant may be exercised by the Holder, in whole or in part, during the Exercise Period by the surrender of this Warrant, together with a completed Exercise Agreement in the form attached hereto, to the Partnership during normal business hours on any Business Day at the Partnership’s office in Houston, Texas (or such other office or agency of the Partnership as it may designate by notice to the Holder).

On a net unit settlement basis, the Warrant Exercised Units shall be deemed to be issued to the Holder or its designees as the record owner of such Common Units as of the close of business on the date or dates on which this Warrant shall have been surrendered and the completed Exercise Agreement delivered (the “Exercise Date”).

The Warrant Exercised Units deemed to be issued on the Exercise Date (which in no event will be less than zero) (the “Net Unit Amount”) shall equal (i) the number of Common Units with respect to which the Holder is exercising purchase rights as specified in the Exercise Agreement, multiplied by (ii) the VWAP (as defined below) on the relevant Exercise Date, minus the Exercise Price, divided by (iii) the arithmetic average of the daily VWAP (as defined below) for the ten (10) consecutive trading days ending on the Exercise Date, provided that any fractional units will be rounded up or down to the nearest whole Common Unit.

As used herein, the term “VWAP” means the dollar volume-weighted average price for the Common Units on the New York Stock Exchange during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg L.P. through its “Volume at Price” function or, if the foregoing does not apply, the dollar volume-weighted average price of the Common Units in the over-the-counter market on the electronic bulletin board for the Common Units during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg L.P., or, if no dollar volume weighted average price is reported for the Common Units by Bloomberg L.P. for such hours, the average of the highest closing bid price and the lowest closing ask price of any of the market makers for the Common Units as reported in the OTC Link or “pink

sheets” by OTC Markets Group Inc. (formerly Pink OTC Markets Inc.). If the VWAP cannot be calculated for the Common Units on a particular date on any of the foregoing bases, the VWAP of the Common Units on such date shall be the fair market value as mutually determined by the Partnership and the Holder.

Section 2. Certain Actions Prohibited. The Partnership will not, by amendment of the Fifth A/R Partnership Agreement or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder of this Warrant in order to protect the exercise privilege of the Holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

Section 3. Anti-Dilution Provisions and Other Adjustments. The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment, from time to time, as follows:

(a) Consolidation or Merger. If, at any time while this Warrant remains outstanding and unexpired, the Partnership shall (i) consolidate or merge with any other entity (regardless of whether the Partnership is the continuing or surviving entity, except that in connection with a consolidation or merger where the Partnership is not the continuing or surviving entity, the Common Units shall be changed into or exchanged for units, stock or other securities of the surviving entity or cash or any other property), (ii) transfer all or substantially all of its properties or assets to any other person or entity or (iii) effect a capital reorganization or reclassification of the Common Units, the Partnership, or such successor entity as the case may be, shall, without payment of any additional consideration therefor, execute a new warrant providing that the Holder shall have the right to exercise such new warrant (upon terms no less favorable to the Holder than those applicable to this Warrant and subject to the same Exercise Period that is applicable to this Warrant) and to receive upon such exercise, in lieu of each Common Unit theretofore issuable upon exercise of this Warrant, the kind and amount of units, shares of stock or other securities, money or property receivable upon such capital reorganization, reclassification, change, consolidation, merger or sale or conveyance by the holder of one Common Unit issuable upon exercise of this Warrant had it been exercised immediately prior to such capital reorganization, reclassification, change, consolidation, merger or sale or conveyance. The provisions of this Section 3(a) shall similarly apply to successive capital reorganizations, reclassifications, changes, consolidations, mergers, sales and conveyances.

(b) Dividends and Distributions in Common Units. If the Partnership shall pay or make a dividend or other distribution on its Common Units in additional Common Units, the Exercise Price in effect at the opening of business on the day following the date fixed for the determination of unitholders entitled to receive such dividend or other distribution (the “Determination Date”) shall be reduced by multiplying such Exercise Price by a fraction, (i) the numerator of which shall be the number of Common Units outstanding as of the close of business on the Determination Date and (ii) the denominator of which shall be the sum of (x) the number of Common Units outstanding at the close of business on the Determination Date and (y) the total number of Common Units constituting such dividend or other distribution. Such reduction shall become effective immediately after the opening of business on the day following the Determination Date. For the purposes of this Section 3(b), the number of Common Units at any time outstanding shall not include Common Units held in the treasury of the Partnership. The Partnership will not pay any dividend or make any distribution on Common Units held in the treasury of the Partnership.

(c) Unit Splits or Combinations. In case the outstanding Common Units shall be subdivided into a greater number of Common Units, the Exercise Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be reduced, and, conversely, in case the outstanding Common Units shall each be combined into a smaller number of Common Units, the Exercise Price in effect at the opening of business on the day following the date upon which such combination becomes effective shall be increased, in each case, to equal the product of the Exercise Price in effect on such date and a fraction, (i) the numerator of which shall be the number of Common Units outstanding immediately prior to such subdivision or combination, as applicable, and (ii) the denominator of which shall be the number of Common Units outstanding immediately after such subdivision or combination,

as applicable. Such reduction or increase, as applicable, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective (the “Alteration Date”).

(d) Reclassifications. The reclassification or change of Common Units (other than any reclassification upon a consolidation or merger to which Section 3(a) shall apply) into securities, including securities other than Common Units, shall be deemed to involve (i) a distribution of such securities other than Common Units to all holders of Common Units (and the effective date of such reclassification shall be deemed to be the Determination Date within the meaning of Section 3(b)), and (ii) a subdivision or combination, as applicable, of the number of Common Units outstanding immediately prior to such reclassification into the number of Common Units outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be the Alteration Date within the meaning of Section 3(c)).

(e) Adjustment of Number of Units. Upon each adjustment in the Exercise Price pursuant to Section 3.1(a)-(d), the number of Common Units purchasable hereunder at the Exercise Price shall be adjusted, to the nearest whole Common Unit, to the product obtained by multiplying such number of Common Units purchasable immediately prior to such adjustment in the Exercise Price by a fraction, (i) the numerator of which shall be the Exercise Price immediately prior to such adjustment and (ii) the denominator of which shall be the Exercise Price immediately thereafter.

(f) Other Provisions Applicable to Adjustments Under This Section. The following provisions will be applicable to the making of adjustments in the Exercise Price provided in this Section 3:

(i) No adjustment in the Exercise Price need be made under Section 3(b) if the Partnership issues or distributes (or holds in a segregated manner pending exercise of this Warrant into Common Units and upon such exercise distributes) to the Holder the Common Units, evidences of indebtedness, assets, rights, options or warrants referred to in those paragraphs that such Holder would have been entitled to receive had this Warrant been exercised for Common Units prior to the happening of such event or the record date with respect thereto.

(ii) All calculations under this Section 3 shall be made to the nearest 1/100th of a cent or to the nearest whole Common Unit, as applicable. No adjustment in the Exercise Price shall be required unless such adjustment (plus any adjustments not previously made by reason of this Section 3(g)(ii)) would require an increase or decrease of at least 1% in such Exercise Price.

(g) Notice to the Holder. The Partnership will deliver to the Holder written notice, at the same time and in the same manner that it is required to give such notice under the Fifth A/R Partnership Agreement of any event or transaction potentially giving rise to an adjustment or modification of the terms and provisions of the Warrant Exercised Units. The Partnership will take all steps reasonably necessary in order to insure that the Holder is able to exercise this Warrant prior to the time of such event or transaction so as to participate in or vote with respect to such event or transaction.

Section 4. Transfer, Exchange and Replacement of Warrant; Representations and Covenants.

(a) Warrant Transferable. The Holder of this Warrant may transfer and assign it to any Affiliate, provided that such party is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), as presently in effect. The Holder of this Warrant may not transfer and assign it to any other person without the prior written consent of the Partnership, which consent shall not be unreasonably withheld. The permitted or approved transfer of this Warrant and all rights hereunder, in whole or in part, is registrable at the office or agency of the Partnership referred to in Section 5 by the Holder in person or by his duly authorized attorney, upon surrender of this Warrant properly endorsed. Upon any permitted or approved transfer of this Warrant to any person, other than a person who is at that time a holder of other Warrants, the Partnership shall have the right to require the Holder and the transferee to make customary representations to the extent reasonably necessary to assure that the transfer will comply with the Securities Act and any applicable state securities laws. The Holder of this Warrant, by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank, shall be deemed negotiable, and that the Holder, when this Warrant shall have been so

endorsed, may be treated by the Partnership and all other persons dealing with this Warrant as the absolute owner and holder for any purpose and as the person entitled to exercise the rights represented by this Warrant and to the registration of transfer hereof on the books of the Partnership; but until due presentment for registration of transfer on such books the Partnership may treat the registered Holder as the owner and holder of this Warrant for all purposes, and the Partnership shall not be affected by any notice to the contrary.

(b) Warrant Exchangeable for Different Denominations. This Warrant is exchangeable, upon the surrender of this Warrant by the Holder at the office or agency of the Partnership referred to in Section 5, for new warrants of like tenor representing in the aggregate the right to purchase the number of Common Units that may be purchased hereunder, each of such new warrants to be imprinted with the same legend appearing on the face of this Warrant and to represent the right to purchase such number of Common Units as shall be designated by the Holder at the time of such surrender.

(c) Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the Partnership of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Partnership, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Partnership, at its expense, will execute and deliver, in lieu thereof, a new warrant of like tenor.

(d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant in connection with any transfer, exchange, or replacement as provided in Section 4(a)-(c), this Warrant shall be promptly cancelled by the Partnership. The Partnership shall pay all taxes (other than securities transfer taxes) and all other expenses and charges payable in connection with the preparation, execution and delivery of Warrants pursuant to this Section 4.

(e) Register. The Partnership shall maintain, at its office in Houston, Texas (or such other office or agency of the Partnership as it may designate by notice to the Holder), a register for this Warrant, in which the Partnership shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee and each prior owner of this Warrant.

(f) Representations and Covenants of the Partnership. The Partnership represents and covenants that all Warrant Exercised Units will, when issued, be validly issued, fully paid and nonassessable (except to the extent such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act). Upon the exercise of this Warrant, the issuance of the Warrant Exercised Units will not be subject to any preemptive or similar rights, other than pursuant to Section 5.8 of the Fifth A/R Partnership Agreement.

(g) Representations and Covenants of the Holder. The Holder is acquiring this Warrant and will acquire the Warrant Exercised Units for its own account, with no present intention of distributing or reselling this Warrant or the Warrant Exercised Units or any part thereof in violation of applicable securities laws. The Holder acknowledges that this Warrant has not been, and when issued the Warrant Exercised Units will not be, registered under the Securities Act or the securities laws of any state in the United States or any other jurisdiction and may not be offered or sold by such Holder unless subsequently registered under the Securities Act (if applicable to the transaction) and any other securities laws or unless exemptions from the registration or other requirements of the Securities Act and any other securities laws are available for the transaction. The Holder represents that it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act, as presently in effect.

Section 5. Notices. All notices, requests, and other communications required or permitted to be given or delivered hereunder to the Holder of this Warrant shall be in writing, and shall be personally delivered, or shall be sent by certified or registered mail, postage prepaid, or by delivery service with proof of delivery, and addressed to the Holder at the address shown for the Holder on the books of the Partnership, or at such other address as shall have been furnished to the Partnership by notice from the Holder. All notices, requests, and other communications required or permitted to be given or delivered hereunder to the Partnership shall be in writing, and shall be personally delivered, or shall be sent by certified or registered mail, postage prepaid, or by delivery service with proof of delivery, and addressed to the office of the Partnership at 2103 CityWest Boulevard, Building #4, Suite 800, Houston, Texas 77042, Attention: General Counsel, or at such other address as shall have been furnished to the Holder of this Warrant by notice from the Partnership. Any such notice, request, or other communication may be sent by facsimile but shall in such case be subsequently confirmed by a writing personally delivered or sent by certified or registered mail as

provided above. All notices, requests, and other communications shall be deemed to have been given either at the time of the delivery thereof to (or the receipt by, in the case of a facsimile) the person entitled to receive such notice at the address of such person for purposes of this Section 5 or, if mailed, at the completion of the third full day following the time of such mailing thereof to such address, as the case may be.

Section 6. GOVERNING LAW. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO ANY CHOICE OF LAW PRINCIPLES OF SUCH STATE.

Section 7. Remedies. The Partnership stipulates that the remedies at law of the Holder of this Warrant in the event of any default or threatened default by the Partnership in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific enforcement of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

(a) Amendments. This Warrant and any provision hereof may not be changed, waived, discharged, or terminated orally, but only by an instrument in writing signed by the party (or any predecessor in interest thereof) against which enforcement of the same is sought.

(b) Descriptive Headings. The descriptive headings of the several sections of this Warrant are inserted for purposes of reference only, and shall not affect the meaning or construction of any of the provisions hereof.

IN WITNESS WHEREOF, the Partnership has caused this Warrant to be signed by its duly authorized officer on this [1^st] day of July 2017.
