 6 

 Section 4.4 Tax Matters. 

(a) The Parties hereby agree and acknowledge that pursuant to Situation 1 of Revenue Ruling 99-6, 1999-1 C.B. 432, the purchase of the CONE Interests hereunder will be treated for federal income Tax purposes by the Buyer as a purchase of the assets of CONE Gathering, and by the Seller as a sale of the CONE
Interests (the “Tax Treatment”). The Parties will prepare and file all Tax Returns in accordance with the Tax Treatment, and will not take any inconsistent position therewith on any Tax Return, or during the course of any audit,
litigation or other proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the
relevant Governmental Authority. 
 (b) The Parties do not expect that any transfer or similar Taxes (“Transfer Taxes”) will
be incurred as a result of or with respect to the sale of the CONE Interests. However, in the event that any Transfer Taxes are due, Buyer and Seller shall bear equally (on a 50/50 basis) any Transfer Taxes that arise in connection with this
Agreement, and Buyer and Seller agree to use their commercially reasonable efforts to mitigate, reduce or eliminate any such Transfer Taxes. Buyer and Seller shall cooperate with one another in the preparation of any necessary Tax Returns and other
related documentation (including any exemption certificates and forms as each may request to establish an exemption) with respect to such Transfer Taxes. 

(c) The Parties hereby agree that any and all gross income allocated to CONE Gathering by the Partnership pursuant to
Section 6.1(d)(iii)(B) of the First Amended and Restated Agreement of Limited Partnership of the Partnership attributable to distributions in respect of the Incentive Distribution Rights in the Partnership after the Effective Time shall be
allocated to the Buyer, as a special allocation by CONE Gathering to Buyer, which shall not be offset by any other allocation in the CONE Gathering LLC Agreement. 

Section 4.5 Notice of Events. 

(a) From the date hereof until the Closing or the earlier termination of this Agreement, Seller shall promptly notify Buyer in writing if
Seller or any of its Affiliates becomes aware of: (i) the occurrence or non-occurrence of any event or the existence of any fact or condition that would cause or constitute a breach of any of the
representations or warranties of Seller in Article II, had any such representation or warranty been made as of the time of Seller’s or its Affiliates discovery of such event, fact or condition, (ii) the filing or initiation of any Legal
Proceeding that seeks to prevent, enjoin or otherwise delay the transactions contemplated by this Agreement, or (iii) any material failure on Seller’s part to comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder, in each case, which breach or failure would reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by this Agreement or to impair Seller’s ability to perform its

against whom such indemnity may be sought prior to such time.  
 Section 7.2
Indemnification. 
 (a) From and after the Closing, each of the Buyer Indemnitees shall be indemnified and held harmless by
Seller for any Damages that any Buyer Indemnitee incurs by reason of, based upon, attributable to, resulting or arising in connection with: 

(i) the incorrectness, falsity, failure to be true and correct or breach of any of Seller’s representations in Article II
(in each case ignoring any qualifications as to “materiality” or words of similar import contained in any such representation or warranty); 

(ii) any Pre-Closing Taxes and/or 

  
 12 

 (iii) any claims, demands and/or causes of action relating to alleging that the

(including any portfolio company of Quantum Energy Partners) and its affiliates to obtain any CONE-related interests from Seller or its Affiliates.

(c) Notwithstanding anything in this Agreement to the contrary, except in the case of fraud, in no event shall Seller’s aggregate
liability for Damages to the Buyer Indemnitees pursuant to Section 7.2(a) exceed the Purchase Price. 
 (d) In the
event any insurance proceeds or other recoveries from third parties are actually realized (in each case calculated net of reasonable third party out-of-pocket costs and
expenses of such recoveries but not including any costs or expenses attributable to increases in insurance premiums) by an Indemnitee or its Affiliates subsequent to the receipt by such Indemnitee of an indemnification or other payment hereunder in
respect of the claims to which such insurance proceeding or third party recovery relate, Seller or Buyer, as applicable, shall make appropriate refunds to the Indemnitor. 

(e) Any Buyer Indemnitee or Seller Indemnitee making a claim for indemnification under this Section 7.2
(an “Indemnitee”) shall notify the indemnifying party (an “Indemnitor”) of the claim in writing after receiving written notice of any Legal Proceeding or other claim against it (if by a third party), describing
in reasonable detail the claim, the amount thereof (if known and quantifiable), and the basis thereof; provided, that the failure to so notify an Indemnitor shall not relieve an Indemnitor of its obligations hereunder, except to the extent
that an Indemnitor’s forfeit rights or defenses are actually prejudiced thereby. The Indemnitor shall have fifteen (15) calendar days from the date upon which the Indemnitor received the claim notice (or sooner if the nature of the claim
so requires) within which to notify the Indemnitee that the Indemnitor desires to assume the defense or prosecution of and any litigation resulting from such Legal Proceeding or other claim giving rise to the Indemnitee’s claim for
indemnification with counsel reasonably acceptable to the Indemnitee and at the Indemnitor’s expense; provided, that (i) the Indemnitee shall be entitled to participate in the defense of such claim and to employ counsel of its
choice for such purpose; provided further, that the fees and expenses of such separate counsel shall be borne entirely by the Indemnitee; provided however that the Indemnitee shall be entitled to participate in any such defense with
separate counsel at the expense of the Indemnitor if (A) so requested by the Indemnitor to participate or (B) in the reasonable opinion of counsel to the Indemnitee, a conflict or potential conflict exists between the Indemnitor and
Indemnitee what would make such separate representation advisable; (ii) Seller shall not be entitled to assume control of such defense if (A) the claim for indemnification relates to or arises in connection with any criminal proceeding,
(B) the claim seeks an injunction or other equitable relief or relief other than for money damages, (C) an adverse determination with respect to such Legal Proceeding or other claim would be materially detrimental to or materially injure
the reputation or business of the Buyer Indemnitee or adversely impact the Buyer Indemnitee’s Tax Liability, (D) such defense 

  
 13 

 
involves defenses of the Buyer Indemnitee that are inconsistent with those available to Seller, (E) Seller does not make an unqualified acknowledgment in writing that it is obligated to
indemnify the Buyer Indemnitee against any Damages that may result from such Legal Proceeding or other claim, or (F) the Buyer Indemnitee reasonably believes that the Damages relating to such Legal Proceeding or other claim could exceed the
maximum amount that the Buyer Indemnitee could then be entitled to recover under this Section 7.2; and (iii) if the Indemnitor shall control the defense or prosecution of any such Legal Proceeding or other claim, such
Indemnitor shall obtain the prior written consent of the Indemnitee (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement of a claim; provided, however, subject to the limitations set forth in
this Section 7.2(e), an Indemnitor may settle or consent to the entry of judgment in respect of such claim without the consent of the Indemnitee, if such settlement or judgment (i) is solely for money damages,
(ii) includes an unconditional release of the Indemnitee from any further Liability in respect of such Legal Proceeding or other claim and (iii) does not contain any admission of wrongdoing on the part of the Indemnitee. If the Indemnitor
makes any payments on any claim pursuant to this Section 7.2(e), the Indemnitor shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnitee to any insurance benefits or other claims of
the Indemnitee with respect to such claim, including any claims against third parties. If the Indemnitor does not assume the defense of such Legal Proceeding or other claim within thirty (30) days of receipt of the Indemnitee’s notice
thereof, the Indemnitee will be entitled to assume such defense, at its sole cost and expense (or, if the Indemnitee incurs Damages with respect to the matter in question for which the Indemnitee is entitled to indemnification pursuant to this
Section 7.2(e), at the expense of the Indemnitor), upon delivery of notice to such effect to the Indemnitor; provided, however, that the Indemnitor (i) shall have the right to participate in the defense of the
Legal Proceeding or other claim at its sole cost and expense and (ii) may at any time thereafter assume defense of the Legal Proceeding or other claim, in which event the Indemnitor shall bear the reasonable fees, costs and expenses of the
Indemnitee’s counsel incurred prior to the assumption by the Indemnitor of defense of such Legal Proceeding or other claim. To the extent legally permissible, each of Buyer and Seller agrees to provide reasonable access to each other Party to
such documentation and information as may be reasonably requested in connection with the defense, negotiation or settlement of any Legal Proceeding involving a third party. 

(f) Any amounts owing under this Section 7.2 shall be made (without interest) by wire transfer of immediately
available funds within three (3) Business Days upon the agreement of Buyer and Seller or after the final, binding determination thereof by a court of competent jurisdiction. All indemnification payments under this
Section 7.2 shall be deemed adjustments to the Purchase Price. 

  
 14 

 Section 7.3 Exclusive Remedy. 

(a) After the Closing, except in the case of fraud, Buyer and Seller acknowledge that the indemnification obligations of each Party set forth
in Section 7.2 are the sole and exclusive remedy of such Party and its Affiliates with respect to this Agreement and the transactions contemplated hereby, whether asserted against (i) the other Party or (ii) the
former, current and future holders of any equity, partnership or limited liability company interest, controlling persons, directors, officers, employees, agents, attorneys, Affiliates, members, managers, general or limited partners, stockholders,
assignees of the other Party. In furtherance of the foregoing, both Buyer and Seller hereby waive, from and after the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action it may have relating
to the subject matter of this Agreement based upon predecessor or successor liability, contribution, tort, strict liability or any Law or otherwise.

SELLER NOR ANY OF ITS AFFILIATES, AGENTS OR REPRESENTATIVES IS MAKING, AND BUYER IS NOT RELYING UPON, ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, BEYOND THOSE EXPRESSLY GIVEN IN Article II, INCLUDING ANY IMPLIED WARRANTY OR
REPRESENTATION AS TO CONDITION, MERCHANTABILITY, SUITABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR TRADE AS TO ANY OF THE ASSETS OF CONE GATHERING OR ANY OF ITS SUBSIDIARIES. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, AND WITHOUT LIMITING
FRAUD CLAIMS, IT IS UNDERSTOOD THAT ANY COST ESTIMATES, FINANCIAL OR OTHER PROJECTIONS, AS WELL AS ANY OTHER INFORMATION, DOCUMENTS OR OTHER MATERIALS OR MANAGEMENT PRESENTATIONS THAT HAVE BEEN OR SHALL HEREAFTER BE PROVIDED TO BUYER OR ANY OF ITS
AFFILIATES, AGENTS OR REPRESENTATIVES ARE NOT AND WILL NOT BE DEEMED TO BE REPRESENTATIONS OR WARRANTIES OF SELLER, AND NO REPRESENTATION OR WARRANTY IS MADE AS TO THE ACCURACY OR COMPLETENESS OF ANY OF THE FOREGOING EXCEPT AS MAY BE EXPRESSLY SET
FORTH IN THIS AGREEMENT. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS AGREEMENT, BUYER UNDERSTANDS AND AGREES THAT ANY INVENTORY, EQUIPMENT, ASSETS, PROPERTIES AND BUSINESS OF CONE GATHERING, AND ANY OF ITS SUBSIDIARIES ARE FURNISHED
“AS IS”, “WHERE IS” AND SUBJECT TO THE REPRESENTATIONS AND WARRANTIES CONTAINED IN Article II, WITH ALL FAULTS AND WITHOUT ANY OTHER REPRESENTATION OR WARRANTY OF ANY NATURE WHATSOEVER.

permitted by applicable Law, agrees to treat any payments made pursuant to this Article VII as adjustments to the Purchase Price for all federal and state income and franchise Tax purposes.

 2. Registration. 

(a) Shelf Registration. The Partnership shall prepare and file a registration statement under the Securities Act (or shall amend
its registration statement filed on May 17, 2017) to permit the public resale of Registrable Securities then outstanding from time to time as permitted by Rule 415 of the Securities Act with respect to all of the Registrable Securities (the
“Shelf Registration Statement”) The Shelf Registration Statement filed pursuant to this Section 2(a) shall be on such appropriate registration form of the Commission as shall be selected by the
Partnership so long as it permits the resale of Registrable Securities from time to time pursuant to Rule 415 under the Securities Act or such other successor rule as is then applicable. The Partnership shall use commercially reasonable efforts to
cause such Shelf Registration Statement to become effective as soon as practicable after the Partnership’s release of earnings for the year ended December 31, 2017 and to remain effective and available for the resale of the Registrable
Securities by the Selling Holders named therein until the date on which all Registrable Securities covered by such Shelf Registration Statement shall have ceased to be a Registrable Security (the “Effectiveness Period”). The
Shelf Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Selling Holders of any and all Registrable Securities covered by such Registration Statement. The
Shelf Registration Statement, when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain
an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Shelf Registration Statement, in the
light of the circumstances under which a statement is made). As soon as practicable following the date that the Shelf Registration Statement becomes effective, but in any event within two Business Days of such date, the Partnership shall provide the
Holders with written notice of the effectiveness of the Shelf Registration Statement. 
 (b) Underwritten Offerings. In the
event that one or more Holders request in a Notice to dispose of a number of Registrable Securities that such Holder or Holders reasonably anticipates will result in gross proceeds of at least $50 million in the aggregate (before deduction of
underwriting discounts) in an Underwritten Offering (a “Demand Underwritten Offering”), the Partnership shall retain one or more underwriters that are reasonably acceptable to such Selling Holders in order to permit such
Selling Holders to effect such disposition through an Underwritten Offering; provided, however, that the Partnership shall have the exclusive right to select the bookrunning managers for such offering. The Partnership and such Selling Holders
shall enter into an underwriting agreement in customary form that is reasonably acceptable to the Partnership and take all reasonable actions as are requested by the managing underwriters to facilitate the Underwritten Offering and the sale of
Registrable Securities therein. No Holder may participate in the Underwritten Offering unless it agrees to sell its Registrable Securities covered by the Registration Statement on the terms and conditions of the underwriting agreement and completes
and delivers all necessary documents and information reasonably required under the terms of such underwriting agreement. Any Holder may withdraw from such Underwritten Offering by notice to the Partnership and the managing underwriter;
provided, such notice is delivered prior to the launch of such Underwritten Offering. 

  
 4 

 (c) Limitations on Underwritten Offerings. The Partnership shall have no obligation
to facilitate or participate in more than an aggregate of four Demand Underwritten Offerings pursuant to this Agreement; provided, that, the Partnership shall not be obligated to effect more than two Underwritten Offerings during any
period of 12 consecutive months and shall not be obligated to effect any Underwritten Offering within 90 days after the pricing of a primary offering of Common Units by the Partnership (other than in connection with any at-the-market offering or similar continuous offering program by the Partnership). 

3. Piggyback Registration. 

(a) Right to Piggyback. At any time if the Partnership proposes to file a Registration Statement for an offering of Common Units
for cash on behalf of the Partnership or another holder of Common Units (other than an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or an offering on
any registration statement that does not permit secondary sales), the Partnership shall notify all Holders of such proposal at least five Business Days before the proposed filing date and shall provide such Holders the opportunity to include in such
offering of Common Units such number of Registrable Securities as such Holders may request in writing (a “Piggyback Registration”). The Partnership shall use commercially reasonable efforts to include such number of
Registrable Securities held by any Holder in such Registration Statement as each such Holder shall request in a Notice received by the Partnership within two Business Days of such Holder’s receipt of the notice from the Partnership. 

(b) Priority on Piggyback Registrations. If the Registration Statement for which the Partnership gives notice under this
Section 3 is for an Underwritten Offering, then any Holder’s ability to include its desired amount of Registrable Securities in such Registration Statement shall be conditioned on such Holder’s inclusion of all
such Registrable Securities in the Underwritten Offering; provided, that, in the event that the managing underwriter of such Underwritten Offering advises the Partnership and the Holder in writing that in its opinion the inclusion of all or
some Registrable Securities would adversely and materially affect the timing or success of the Underwritten Offering, the Partnership will include in such Underwritten Offering such amount of Registrable Securities that the managing underwriter
advises may be sold in such offering as follows: (i) in the event of a Demand Underwritten Offering, first, the Registrable Securities to be included by the Holder(s) requesting such Demand Underwritten Offering, second, the
Common Units to be included by the Partnership, to the extent it elects to sell Common Units in such Demand Underwritten Offering; and third, the Common Units, if any, proposed to be included in such Demand Underwritten Offering by any other
holders of Common Units; (ii) in the event of a Piggyback Registration in connection with an Underwritten Offering of Common Units on behalf of a holder of Common Units other than the Partnership (other than a Demand Underwritten Offering),
first, the Common Units requested to be included in such Underwritten Offering by the holder of Common Units that demanded such Underwritten Offering; second, the Common Units requested to be included in such Underwritten Offering by
the Partnership; third, the Registrable Securities owned by any Holder, pro rata based on the number of Registrable Securities initially requested by them to be included in such Underwritten 

  
 5 

 
Offering and fourth, the Common Units, if any, proposed to be included in the Underwritten Offering by any other holders of Common Units; or (iii) in the event of a Piggyback
Registration in connection with an Underwritten Offering of Common Units that is initiated by the Partnership for a primary offering of Common Units by the Partnership, first, the Common Units to be included in such Underwritten Offering by
the Partnership; second, the Registrable Securities owned by any Holder, pro rata based on the number of Registrable Securities initially requested by them to be included in such Underwritten Offering; and third, the Common Units, if
any, proposed to be included in the Underwritten Offering by any other holders of Common Units. No Holder may participate in an Underwritten Offering unless such Holder agrees to sell its Registrable Securities covered by the Registration Statement
on the terms and conditions of the underwriting agreement and completes and delivers all necessary documents and information reasonably required under the terms of such underwriting agreement. Any Holder may withdraw from such Underwritten Offering
by notice to the Partnership and the managing underwriter; provided, such notice is delivered prior to the launch of such Underwritten Offering. The Partnership shall have the right to terminate or withdraw any Registration Statement or
Underwritten Offering initiated by it prior to the Effective Date of the Registration Statement or the pricing date of the Underwritten Offering, as applicable. 

4. Sale Procedures. In connection with its obligations under this Agreement, the Partnership shall: 

(a) prepare and file with the Commission such amendments and supplements to the Shelf Registration Statement and the prospectus used in
connection therewith as may be necessary to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities covered by the Shelf Registration Statement; 
 (b) furnish to each Selling Holder (i) as far in advance as reasonably
practicable before filing a Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference

therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing a Registration Statement or supplement or amendment thereto and (ii) such number of copies of such Registration
Statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration
Statement; provided, however, that the Partnership will not have any obligation to provide any document pursuant to clause (ii) hereof that is available on the Commission’s website; 

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Registration
Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the managing underwriter, shall reasonably request; provided, however, that the Partnership shall

Registration Statement or any post-effective amendment thereto, when the same has become effective and (ii) any written comments from the Commission with respect to any Registration Statement or any document incorporated by reference therein

under which a statement is made), (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement, or the initiation of any proceedings for that purpose or (iii) the receipt

reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

Registration Statements and the disposition of all Registrable Securities covered by each Registration Statement; and 
 (m) in connection
with any Demand Underwritten Offering, the Partnership will use commercially reasonable efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in
presentations, meetings and road shows. 
 5. Suspension. Each Selling Holder, upon receipt of notice from the Partnership of
the happening of any event of the kind described in Section 4(e), shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s
receipt of the copies of the supplemented or amended prospectus contemplated by such subsection, or until it is advised in writing by the Partnership that the use of the prospectus may be resumed, and receipt of copies of any additional or
supplemental filings incorporated by reference in the prospectus. 
 6. Expenses. Except as set forth in an underwriting
agreement for the applicable Underwritten Offering or as otherwise agreed between a Selling Holder and the Partnership, all costs and expenses of a Registration Statement filed or an Underwritten Offering that includes Registrable Securities
pursuant to this Agreement (other than underwriting discounts and commissions on Registrable Securities and fees and expenses of counsel and advisors to Selling Holders) shall be paid by the Partnership. 

7. Delay Right. Notwithstanding anything to the contrary in this Agreement, if the General Partner determines that the
Partnership’s compliance with its obligations in this Agreement would be detrimental to the Partnership because such registration or an Underwritten Offering thereunder would (a) materially interfere with a significant acquisition,
reorganization or other similar transaction involving the Partnership, (b) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (c) render the
Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to postpone compliance with such obligations for a period of not more than six months; provided, however, that
such right may not be exercised more than twice in any 24-month period.

 8. Indemnification. 

(a) The Partnership shall, to the fullest extent permitted by law, but subject to the limitations expressly provided in this Agreement,
indemnify and hold harmless each Selling Holder, its officers, directors and each Person who controls the Selling Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Indemnified Persons”)
from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions,
suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (hereinafter referred to
in this Section 8 as a “claim” and in the plural as “claims”) based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material
fact contained in any Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus under which any Registrable Securities were registered or sold by such Selling Holder under the Securities Act, or arising out
of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Partnership shall
not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, preliminary
prospectus, final prospectus or issuer free writing prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof. 

(b) Each Selling Holder shall, to the fullest extent permitted by law, indemnify and hold harmless the Partnership, the General Partner, the
General Partner’s officers and directors and each Person who controls the Partnership or the General Partner (within the meaning of the Securities Act) and any agent thereof to the same extent as the foregoing indemnity from the Partnership to
the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement, preliminary prospectus, final prospectus or free
writing prospectus relating to the Registrable Securities held by such Selling Holder. 
 (c) The provisions of this Section 8 shall be
in addition to any other rights to indemnification or contribution that a Person entitled to indemnification under this Section 8 may have pursuant to law, equity, contract, or otherwise. 

9. Facilitation of Sales Pursuant to Rule 144. To the extent it shall be required to do so under the Exchange Act, the
Partnership shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports required under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and
shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the
exemption provided by Rule 144. Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, the Partnership shall deliver to such Holder a written statement as to whether it has complied with such requirements.

 10. Miscellaneous. 

(a) Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible,
to ascertain, and it is therefore agreed that each party, in addition to and without limiting any other remedy or right it may have, will have the right to seek an injunction or other equitable relief in any court of competent jurisdiction,
enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives, to the fullest extent permitted by law, any and all defenses it may have on the ground of lack of jurisdiction or
competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity that such party may have. 

(b) Amendments and Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed by the
Partnership and Holders that hold a majority of the Registrable Securities as of the date of such waiver or amendment; provided, that any waiver or amendment that would have a disproportionately adverse effect on a Holder relative to the
other Holders shall require the consent of such Holder. The Partnership shall provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement
shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any
manner impair the exercise of any such right. 
 (c) Notices. All notices and other communications given or made pursuant
hereto shall be in writing and shall be deemed to have been duly given or made if delivered personally or sent by overnight courier (with evidence of confirmation of receipt) to the Parties at the following addresses:

be binding upon and inure to the benefit of the Parties hereto and their respective heirs, executors, administrators, successors, legal representatives and permitted assigns. The rights of a Holder hereunder may be transferred, assigned, or

doubt, Noble Midstream hereby acknowledges and agrees that the registration rights under Section 7.12 of the Partnership Agreement, will no longer be available to Noble Midstream and its Affiliates and Noble Midstream for itself and for and on
behalf of its Affiliates renounces any claim to the registration rights under Section 7.12 of the Partnership Agreement. 
 (f) No
Third Party Beneficiaries. Nothing in this Agreement, whether express or implied, shall be construed to give any Person, other than the parties hereto or their respective successors and permitted assigns, any legal or equitable right,
remedy, claim or benefit under or in respect of this Agreement. 
 (g) Execution and Counterparts. This Agreement may be
executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile or
electronic mail transmission, such signature shall create a valid and binding obligation of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or
electronic mail transmission were the original thereof. 
 (h) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof. 
 (i) Governing Law. This Agreement and the
exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other
jurisdiction) to the extent such rules or provisions would cause the application of the laws of any jurisdiction other than the State of Delaware. 

  
 11 

 (j) Waiver of Jury Trial. Each of the parties to this Agreement hereby agrees to
waive its respective rights to a jury trial of any claim or cause of action based upon or arising out of this Agreement. The scope of this waiver is intended to be all-encompassing of any and all disputes that
may be filed in any court and that relate to the subject matter of this Agreement, including contract claims, tort claims and all other common law and statutory claims. Each party hereto acknowledges that this waiver is a material inducement to
enter into this Agreement, that each has already relied on this waiver in entering into this Agreement, and that each will continue to rely on this waiver in their related future dealings. Each party hereto further warrants and represents that it
has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING
(OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION 10(i) AND EXECUTED BY EACH OF THE PARTIES HERETO), AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the Parties shall use their reasonable efforts to find and employ an alternative means to achieve the same or
substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and
restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
 (l) Entire
Agreement. This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior contracts or agreements with respect to the subject matter hereof and the matters addressed or
governed hereby, whether oral or written.

shall terminate as to any Holder, on the earlier to occur of (i) when all Registrable Securities held by such Holder no longer constitute Registrable Securities and (ii) the third anniversary of the the effectiveness of the Shelf
