Section 3.39     Disclosure Controls and Procedures . To the extent required by Rule 13a-15 under the Exchange Act, the Partnership has established and maintains an effective system of “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that complies with the requirements of the Exchange Act; the Partnership’s “disclosure controls and procedures” are reasonably designed to ensure that all information (both financial and non-financial) required to be disclosed by the Partnership in the reports to be filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Exchange Act, and that all such information is accumulated and communicated to the Partnership’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the Chief Executive Officer and Chief Financial Officer of the General Partner required under the Exchange Act with respect to such reports.

Section 3.40     Internal Controls . The Partnership Entities maintain systems of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that comply with the requirements of the Exchange Act and have been designed by, or under the supervision of, their respective principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including, but not limited to, internal accounting controls sufficient to provide reasonable assurance that (a) transactions are executed in accordance with management’s general or specific authorizations; (b) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (c) access to assets is permitted only in accordance with management’s general or specific authorization; and (d) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

ARTICLE IV
REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

Each Purchaser, severally and not jointly, hereby represents and warrants to the Partnership that:

Section 4.1     Existence . Such Purchaser is duly organized and validly existing and in good standing under the Laws of its jurisdiction of organization, with all requisite power and authority to own, lease, use and operate its properties and to conduct its business as currently conducted, except where the failure to have such power or authority would not prevent the consummation of the transactions contemplated by this Agreement and the Registration Rights Agreement.

Section 4.2     Authorization, Enforceability . Such Purchaser has all necessary corporate, limited liability company or partnership power and authority to execute, deliver and perform its obligations under this Agreement and the Registration Rights Agreement and to consummate the transactions contemplated hereby and thereby, and the execution, delivery and performance by such Purchaser of this Agreement and the Registration Rights Agreement has been duly authorized by all necessary action on the part of such Purchaser; and this Agreement and the Registration Rights Agreement constitute the legal, valid and binding obligations of such Purchaser, enforceable in accordance with their terms, subject to the Enforceability Exceptions.

Section 4.3     No Breach . The execution, delivery and performance of this Agreement and the Registration Rights Agreement by such Purchaser and the consummation by such Purchaser of the transactions contemplated hereby

and thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the property or assets of such Purchaser is subject, (b) conflict with or result in any violation of the provisions of any certificate of limited partnership, formation or incorporation, agreement of limited partnership, limited liability company agreement, bylaws or any other organizational documents of such Purchaser, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the cases of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not prevent the consummation of the transactions contemplated by this Agreement and the Registration Rights Agreement.

Section 4.4     Certain Fees . No fees or commissions are or will be payable by such Purchaser to brokers, finders, or investment bankers with respect to the purchase of any of the Purchased Units or the consummation of the transaction contemplated by this Agreement.

Section 4.5     No Side Agreements . There are no other agreements by, among or between such Purchaser and any of its Affiliates, on the one hand, and the Partnership or any of its Affiliates, on the other hand, with respect to the transactions contemplated hereby, other than the Operative Documents, nor promises or inducements for future transactions between or among any of such parties.

Section 4.6     Investment . The Purchased Units are being acquired for such Purchaser’s own account, the account of its Affiliates, or the accounts of clients for whom such Purchaser exercises discretionary investment authority (all of whom such Purchaser hereby represents and warrants are “accredited investors” within the meaning of Rule 501(a) of Regulation D promulgated by the Commission pursuant to the Securities Act), not as a nominee or agent, and with no present intention of distributing the Purchased Units or any part thereof, and such Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the securities laws of the United States or any state, without prejudice, however, to such Purchaser’s right at all times to sell or otherwise dispose of all or any part of the Purchased Units under a registration statement under the Securities Act and applicable state securities laws or under an exemption from such registration available thereunder (including, without limitation, if available, Rule 144 promulgated thereunder). If such Purchaser should in the future decide to dispose of any of the Purchased Units, the Purchaser understands and agrees (a) that it may do so only in compliance with the Securities Act and applicable state securities law, as then in effect, including a sale contemplated by any registration statement pursuant to which such securities are being offered, or pursuant to an exemption from the Securities Act, and (b) that stop-transfer instructions to that effect will be in effect with respect to such securities.

Section 4.7     Nature of Purchaser . Such Purchaser represents and warrants to, and covenants and agrees with, the Partnership that, (a) it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated by the Commission pursuant to the Securities Act, (b) by reason of its business and financial experience it has such knowledge, sophistication and experience in making similar investments and in business and financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units and (c) is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

Section 4.8     Restricted Securities . Such Purchaser understands that the Purchased Units are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from the Partnership in a transaction not involving a public offering and that under such Laws and applicable regulations such securities may not be resold absent registration under the Securities Act or an exemption therefrom. In this connection, such Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

Section 4.9     Legend . Such Purchaser understands that the book entry evidencing the Purchased Units will bear the legend required by the Partnership Agreement as well as a legend substantively consistent with the following legend: “These securities have not been registered under the Securities Act of 1933, as amended (the “ Securities Act ”). These securities may not be sold or offered for sale except pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from registration thereunder, in each case in accordance with all applicable

securities laws of the states or other jurisdictions, and in the case of a transaction exempt from registration, such securities may only be transferred if the transfer agent for such securities has received documentation satisfactory to it that such transaction does not require registration under the Securities Act.”

Section 4.10     Partnership Information . Such Purchaser acknowledges and agrees that the Partnership has provided or made available to such Purchaser (through EDGAR, the Partnership’s website or otherwise) all SEC Reports, as well as all press releases or investor presentations issued by the Partnership through the date of this Agreement that are included in a filing by the Partnership on Form 8-K or clearly posted on the Partnership’s website.

Section 4.11     Placement Agent Reliance . Such Purchaser agrees that the Placement Agent may rely upon the representations and warranties made by such Purchaser to the Partnership in Sections 4.6 , 4.7 and 4.8 of this Agreement.

Section 4.12     Short Selling . Such Purchaser represents that it has not entered into any Short Sales of the Common Units owned by it since the time it first began discussions with the Partnership or the Placement Agents about the transactions contemplated by this Agreement; provided, however , subject to such Purchaser’s compliance with its obligations under the U.S. federal securities laws and its internal policies, the above shall not apply, in the case of a Purchaser that is a large multi-unit investment or commercial banking organization, to activities in the normal course of trading units of such Purchaser; provided, further , that subject to such Purchaser’s compliance with its obligations under the U.S. federal securities laws and its internal policies: (a) such Purchaser, for purposes hereof, shall not be deemed to include any employees, subsidiaries or Affiliates that are effectively walled off by appropriate “Chinese Wall” information barriers approved by such Purchaser’s legal or compliance department (and thus have not been privy to any information concerning this transaction) (a “ Walled Off Person ”) and (b) the foregoing representations in this paragraph shall not apply to any transaction by or on behalf of such Purchaser that was effected by a Walled Off Person in the ordinary course of trading without the advice or participation of such Purchaser or receipt of confidential or other information regarding this transaction provided by such Purchaser to such entity.

ARTICLE V
COVENANTS

Section 5.1     Taking of Necessary Action . Each of the parties hereto shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement. Without limiting the foregoing, the Partnership and each Purchaser shall use its commercially reasonable efforts to make all filings and obtain all Consents of Governmental Authorities that may be necessary or, in the reasonable opinion of the other parties, as the case may be, advisable for the consummation of the transactions contemplated by the Operative Documents; provided , however , and notwithstanding anything to the contrary, that no Purchaser is under any obligation by reason of this Section 5.1 to make, seek or receive any filings, notifications, consents, determinations, authorizations, permits, approvals, licenses or the like with or provide any documentation or information to any regulatory or self-regulatory body having jurisdiction over the Partnership or Purchaser other than information that is already included in this Agreement or is otherwise in the public domain other than as may be requested by the Commission or pursuant to any applicable securities or “Blue Sky” laws of the United States. The Partnership shall promptly and accurately respond, and shall use its commercially reasonable efforts to cause its transfer agent to respond, to reasonable requests for information (which is otherwise not publicly available) made by a Purchaser or its auditors relating to the actual holdings of such Purchaser or its accounts; provided , that the Partnership shall not be obligated to provide any such information that could reasonably result in a violation of applicable Law or conflict with the Partnership’s insider trading policy or a confidentiality obligation of the Partnership. The Partnership shall use its commercially reasonable efforts to cause its transfer agent to reasonably cooperate with each Purchaser to ensure that the Purchased Units are validly and effectively issued to such Purchaser and that such Purchaser’s ownership of the Purchased Units following the Closing is accurately reflected on the appropriate books and records of the Partnership’s transfer agent.

Section 5.2     Other Actions . The Partnership shall file prior to the Closing a supplemental listing application with the NYSE to list the Purchased Units.

Section 5.3     Contribution Transaction . The Partnership will distribute to NBL Midstream an amount equal to the net proceeds of this offering as cash consideration.

If any action at law or equity is necessary to enforce or interpret the terms of any Operative Document, the prevailing party shall be entitled to reasonable attorney’s fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. Any legal fees of Gibson, Dunn & Crutcher LLP in excess of $75,000 shall be paid pro rata by all the Purchasers in proportion to the number of Purchased Units purchased by each.

Section 5.5     Non-Public Information . On or before 9:00 a.m., New York local time, on the Business Day immediately following the date hereof, the Partnership shall issue a press release (the “Press Release”) announcing the entry into this Agreement and describing the terms of the transactions contemplated by this Agreement and any other material, nonpublic information that the Partnership may have provided any Purchaser at any time prior to the issuance of the Press Release. On or before the fourth Business Day following the date hereof, the Partnership shall file a Current Report on Form 8-K with the Commission describing the terms of the transactions contemplated by the Operative Documents, and including as an exhibit to such Current Report on Form 8-K the Operative Documents, in the form required by the Exchange Act.

ARTICLE VI
INDEMNIFICATION

Section 6.1     Indemnification by the Partnership . The Partnership agrees to indemnify each Purchaser and its Representatives (collectively, “ Purchaser 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, and promptly upon demand, pay or reimburse each of them for all 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 Partnership contained herein, provided that such claim for indemnification relating to a breach of the representations or warranties is made prior to the expiration of the survival period for such representations or warranties; and provided further , that no Purchaser Related Party shall be entitled to recover special, consequential (including lost profits) or punitive damages. Notwithstanding anything to the contrary, consequential damages shall not be deemed to include diminution in value of the Purchased Units, which is specifically included in damages covered by Purchaser Related Parties’ indemnification above.

Section 6.2     Indemnification Procedure . Promptly after receipt by an indemnified party under this Article VI of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Article VI , notify the indemnifying party in writing of the claim or the commencement of that action; provided, however , that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under Section 6.1 of this Article VI except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further , that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Article VI . If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be

liable to the indemnified party under this Article VI for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however , that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Article VI if (a) the indemnified party and the indemnifying party shall have so mutually agreed; (b) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (c) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (d) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel to the extent required by Section 6.1 hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (x) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (y) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

Section 7.7     Removal of Legend . The Partnership, at its sole cost, shall remove the legend described in Section 4.9 (or instruct its transfer agent to so remove such legend) from the certificates evidencing Purchased Units issued and sold to each Purchaser pursuant to this Agreement if (a) such Purchased Units are sold pursuant to an effective registration statement under the Securities Act, (b) such Purchased Units are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Partnership), or (c) such Purchased Units are eligible for sale under Rule 144, without the requirement for the Partnership to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities and without volume or manner of sale restrictions. In connection with a sale of the Purchased Units by a Purchaser in reliance on Rule 144, the applicable Purchaser shall deliver to the transfer agent and the Partnership a customary representation letter providing to the transfer agent and the Partnership any information the Partnership deems reasonably necessary to determine that the sale of the Purchased Units is made in compliance with Rule 144, including, as may be appropriate, a certification that the Purchaser is not an Affiliate of the Partnership and regarding the length of time the Purchased Units have been held.

After any Purchaser or its permitted assigns have held the Purchased Units for such time as non-Affiliates are permitted to sell without volume limitations under Rule 144, if the certificate for such Purchased Units still bears the restrictive legend referred to in Section 4.9 , the Partnership 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 4.9 from the Purchased Units, and the Partnership shall bear all costs associated therewith, regardless of whether the request is made in connection with a sale or otherwise, so long as such Purchaser or its permitted assigns provide to the Partnership any information the Partnership deems reasonably 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 the Partnership (and a covenant to inform the Partnership 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 Purchased Units have been held.

Section 7.8     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.

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.

This Agreement may be executed in any number of counterparts and by different 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. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

Section 7.11     Termination .

(a)    Notwithstanding anything herein to the contrary, this Agreement may be terminated at any time at or prior to the Closing by any Purchaser (with respect to such Purchaser only), upon a breach in any material respect by the Partnership of any covenant or agreement set forth in this Agreement.

(b)    Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate at any time at or prior to the Closing:

(i)    if a statute, rule, order, decree or regulation shall have been enacted or promulgated, or if any action shall have been taken by any Governmental Authority of competent jurisdiction that permanently restrains, permanently precludes, permanently enjoins or otherwise permanently prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal; or

(ii)    if the Closing shall not have occurred by June 30, 2017.

(c)    In the event of the termination of this Agreement as provided in this Section 7.11 , this Agreement shall forthwith become null and void. In the event of such termination, there shall be no liability on the part of any party hereto, except as set forth in Section 5.3 and Article VI of this Agreement.

Section 7.12     Recapitalization, Exchanges, Etc. Affecting the Common Units . The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all equity interests of the Partnership or any successor or assign of the Partnership (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for or in substitution of, the Common Units, and shall be appropriately adjusted for combinations, unit splits, recapitalizations and the like occurring after the date of this Agreement and prior to the Closing.
