CONE Gathering, the General Partner and the Partnership are sometimes referred to in this Agreement individually as a “Party” and collectively as the “Parties.”

WHEREAS, CONE Midstream DevCo I GP LLC, a Delaware limited liability company, owns a 75% general partner interest in DevCo I LP, and CONE Gathering owns a 25% limited partner interest in DevCo I LP;

WHEREAS, in connection with the Closing (as defined below), CONE Gathering desires to contribute, assign, transfer, convey and deliver to the Partnership or its designee(s), and the Partnership desires to receive, accept and acquire (or cause its designee(s) to receive, accept and acquire) from CONE Gathering, a 25% limited partner interest in DevCo I LP held by CONE Gathering, and, in exchange, the Partnership desires to deliver, or cause to be delivered, to CONE Gathering or its designee(s) the Total Consideration (as defined below), all in accordance with the terms of this Agreement (the “Transaction”);

WHEREAS,

(a)     the Conflicts Committee (the “Conflicts Committee”) of the Board of Directors (the “Board of Directors”) of the General Partner has previously:

(i)     received an opinion (the “Fairness Opinion”) of Evercore Group L.L.C., the financial advisor to the Conflicts Committee (the “Financial Advisor”), that the Total Consideration to be paid by the Partnership pursuant to the Transaction is fair, from a financial point of view, to the Partnership and its unitholders, other than CONE Gathering, the General Partner and their respective Affiliates (collectively, the “Public Unitholders”);

(ii)     after an evaluation of, among other things, the Transaction, the Fairness Opinion and the proposed terms and conditions of this Agreement and the other Transaction Documents (as defined below), determined in good faith that the Transaction, including this Agreement and the other Transaction Documents, are fair and reasonable to, and in the best interests of, the Partnership and the Public Unitholders;

(iii)     unanimously approved the Transaction, the Transaction Documents and the transactions contemplated thereby upon the terms and conditions set forth in the Transaction Documents, such approval constituting “Special Approval” for purposes of the Partnership Agreement (as defined below); and

(iv)     unanimously recommended that the Board of Directors (A) approve the Transaction, the Transaction Documents and the transactions contemplated thereby upon the terms and conditions set forth in the Transaction Documents and (B) cause the Partnership or its designee(s) to enter into the Transaction Documents and consummate the Transaction upon the terms and conditions set forth in the Transaction Documents; and

(b)     subsequently, the Board of Directors has approved the Transaction, the Transaction Documents and the transactions contemplated thereby upon the terms and conditions set forth in the Transaction Documents; and

2.4    Assumed Liabilities. Except for Excluded Liabilities as provided in Section 2.5 and subject to the indemnification rights provided in Section 8.2, at the Effective Time, the Partnership Group agrees to assume and to pay, discharge and perform as and when due, all Liabilities that first accrue, are caused by, arise out of, are associated with, are in respect of, or are incurred, in each case, at any time prior to, on or after the Effective Time, in connection with the ownership of the Subject Interests or other activities occurring in connection with and attributable to the ownership of the Subject Interests (collectively, the “Assumed Liabilities”).

CONE Gathering is duly qualified as a foreign limited liability company to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Sponsor Material Adverse Effect.

Each of this Agreement and any other Transaction Document to which CONE Gathering is or will be a party constitutes or will constitute, upon execution and delivery by CONE Gathering, the valid and binding obligation of CONE Gathering, enforceable against CONE Gathering in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity (whether applied in a proceeding at law or in equity).

3.3    No Conflict. Each of this Agreement, the other Transaction Documents to which CONE Gathering is or will be a party and the execution and delivery hereof and thereof by CONE Gathering do not, and the fulfilment and compliance with the terms and conditions hereof and thereof and the consummation of the transactions contemplated hereby and thereby will not:

(a)    conflict with any of the provisions of the certificate of formation or limited liability company agreement of CONE Gathering;

(e)    result in the revocation, cancellation, suspension or modification of any Consent possessed by CONE Gathering that is necessary or desirable for the ownership, lease or operation of its properties and other assets in the conduct of its business as now conducted;

except, in the case of clauses (b), (c), (d) and (e), as would not have, individually or in the aggregate, a Sponsor Material Adverse Effect.

3.4    Consents. No consent, approval, license, permit, order, waiver, or authorization of, or registration, declaration, or filing with any Governmental Authority or other Person (each a “Consent”) is required to be obtained or made by or with respect to CONE Gathering or the Subject Interests in connection with:

(a)    the execution, delivery, and performance of this Agreement or the other Transaction Documents, or the consummation of the transactions contemplated hereby and thereby; or

(b)    the enforcement against CONE Gathering of its obligations hereunder and thereunder;

3.5    Laws and Regulations; Litigation. There are no pending or, to the knowledge of CONE Gathering, threatened claims, fines, actions, suits, demands, investigations or proceedings or any arbitration or binding dispute resolution proceeding (collectively, “Proceedings”) against

CONE Gathering or against or affecting the Subject Interests or the ownership of the Subject Interests that (i) would individually, or in the aggregate, have a Sponsor Material Adverse Effect or (ii) seek any material injunctive relief with respect to the Subject Interests.

3.6    Management Projections and Budgets. Over the course of the negotiation and review of the Transaction, CONE Gathering and representatives of certain of its Affiliates have provided various materials to the Conflicts Committee (including those provided to the Financial Advisor) as part of the Conflicts Committee’s review of the Transaction and the Subject Interests, including various presentations, budgets and financial models and including all updates and revisions to such materials (all such materials, collectively, the “Conflicts Committee Information”). With respect to the Conflicts Committee Information:

(a)    the projections, budgets and other forward-looking information included in the Conflicts Committee Information, when considering all updates and revisions provided as a part thereof, have a reasonable basis, were prepared in good faith and are consistent with the current expectations of the management of CONE Gathering and its Affiliates; and

(b)    to the knowledge of CONE Gathering, the Conflicts Committee Information (considering all updates and revisions provided as a part thereof) does not contain any misstatement of a material fact or any omission of a material fact necessary to make the Conflicts Committee Information, taken as a whole and in the light of the circumstances under which it was made, not misleading.

3.7    Title to Subject Interests.

(a)    The Subject Interests (i) represent a 25% limited partner interest in DevCo I LP and (ii) were duly authorized and validly issued and are fully paid and non-assessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the DRULPA). The Subject Interests are not subject to and were not issued in violation of any

purchase option, call option, right of first refusal, preemptive right, subscription right or any similar right under any provision of local or state law applicable to the Subject Interests, the DevCo I Partnership Agreement or any contract, arrangement or agreement to which CONE Gathering or any of its Affiliates is a party or to which it or any of their respective properties or assets is otherwise bound.

(b)    CONE Gathering has good and valid record and beneficial title to the Subject Interests, free and clear of any and all Liens (other than restrictions on transfer under applicable federal and state securities laws), and, except as provided or created by the DevCo I Partnership Agreement, the Securities Act or applicable securities laws, the Subject Interests are free and clear of any restrictions on transfer, Taxes or claims. There are no options, warrants, purchase rights, contracts, commitments or other securities exercisable or exchangeable for the Subject Interests, or for the repurchase or redemption of the Subject Interests. Immediately after the Closing, the Partnership will have good and valid record and beneficial title to the Subject Interests, free and clear of any Liens (other than restrictions on transfer under applicable federal and state securities laws).

3.8    Brokerage Arrangements. None of CONE Gathering or any of its Affiliates has entered, directly or indirectly, into any agreement with any person, firm or corporation that would obligate any Group Member to pay any commission, brokerage or “finder’s fee” or other fee in connection with this Agreement or the transactions contemplated hereby.

3.9    No Adverse Changes. Since December 31, 2015, there has been no Sponsor Material Adverse Effect with respect to CONE Gathering.

3.10    No Preferential Rights. The Subject Interests are not subject to any right or agreement that enables any Person to purchase or acquire, including by way of a right of first refusal, right of first offer, or similar right, the Subject Interests or any portion of or interest in the Subject Interests as a result of or in connection with (a) the contribution, assignment or other transfer of the Subject Interests, (b) the execution, delivery or performance of this Agreement or (c) the consummation of the transactions contemplated hereby.

3.11    Accredited Investor. CONE Gathering (or its designees that receive the New Common Units) is an “accredited investor,” as such term is defined in Regulation D of the Securities Act, and will acquire the New Common Units for its own account and not with a view to a sale or distribution thereof in violation of the Securities Act, and the rules and regulations thereunder, any applicable state blue sky laws or any other applicable securities laws. CONE Gathering (or its designees that receive the New Common Units) has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of an investment in the New Common Units to be acquired hereby. CONE Gathering (or its

designees that receive the New Common Units) acknowledges that the New Common Units have not been registered under applicable federal and state securities laws and that the New Common Units may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of unless such transfer, sale, assignment, pledge, hypothecation or other disposition is registered under applicable federal and state securities laws or is made pursuant to an exemption from registration under any federal or state securities laws.

3.12    No Other Representations or Warranties. Except for the representations and warranties made in this Article III, CONE Gathering makes no other express or implied representation or warranty with respect to the Subject Interests or the transactions contemplated by this Agreement and disclaims any other representations or warranties.

Each Partnership Party is duly qualified as a foreign limited liability company or limited partnership, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Partnership Material Adverse Effect.

4.2    Authority and Approval; Enforceability. Each Partnership Party has the limited liability company power or limited partnership power, as the case may be, and authority to execute and deliver this Agreement and any other Transaction Document to which it is or will be a party, to consummate the transactions contemplated hereby and thereby and to perform all the terms and conditions hereof and thereof to be performed by it. The execution and delivery by each Partnership Party of this Agreement and any other Transaction Document to which it is or will be a party, the performance by it of all the terms and conditions hereof and thereof to be performed by it and the consummation of the transactions contemplated hereby and thereby have been duly authorized and approved by all requisite limited liability company or limited partnership, as the case may be, action of such Partnership Party. Each of this Agreement and

any other Transaction Document to which each Partnership Party is or will be a party constitutes or will constitute, upon execution and delivery by such Partnership Party, the valid and binding obligation of such Partnership Party, enforceable against such Partnership Party in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity (whether applied in a proceeding at law or in equity).

4.3    No Conflict. Each of this Agreement, the other Transaction Documents to which each Partnership Party is or will be a party and the execution and delivery hereof and thereof by such Partnership Party do not, and the fulfilment and compliance with the terms and conditions hereof and thereof and the consummation of the transactions contemplated hereby and thereby will not:

(a)    conflict with any of the provisions of the certificate of formation, limited liability company agreement, certificate of limited partnership, partnership agreement or other organizational document of such Partnership Party;

(d)    result in the revocation, cancellation, suspension or modification of any Consent possessed by such Partnership Party that is necessary or desirable for the ownership, lease or operation of its properties and other assets in the conduct of its business as now conducted;

except, in the case of clauses (b), (c), and (d), as would not have, individually or in the aggregate, a Partnership Material Adverse Effect.

4.4    Consents. No Consent is required to be obtained or made by or with respect to any Partnership Party in connection with:

From and after the Closing Date, subject to the other provisions of this Article VIII, the Partnership Parties shall, jointly and severally, indemnify and hold CONE Gathering and its Affiliates, directors, officers, employees, agents and representatives (together with CONE Gathering, the “CONE Indemnitees”) harmless from and against any and all damages (including exemplary damages and penalties), losses, deficiencies, costs, expenses, obligations, fines, expenditures, claims and liabilities, including reasonable counsel fees and reasonable expenses of investigation, defending and prosecuting litigation (collectively, the “Damages”), suffered by the CONE Indemnitees as a result of, caused by, arising out of, or in any way relating to (%3) any breach of a representation or warranty of the Partnership Parties contained in this Agreement, (%3) any breach of any agreement or covenant

contained in this Agreement on the part of the Partnership Parties or (%3) any of the Assumed Liabilities.

8.2    Indemnification of the Partnership Parties. Solely for the purpose of indemnification in this Section 8.2, the representations and warranties of CONE Gathering in this Agreement (other than the representation and warranty contained in Section 3.9) shall be deemed to have been made without regard to any materiality or Sponsor Material Adverse Effect or knowledge qualifiers. From and after the Closing Date, subject to the other provisions of this Article VIII, CONE Gathering shall indemnify and hold the Partnership Parties and their respective Affiliates, directors, officers, employees, agents and representatives (together with the Partnership Parties, the “Partnership Indemnitees”) harmless from and against any and all Damages suffered by the Partnership Indemnitees as a result of, caused by, arising out of, or in any way relating to (%3) any breach of a representation or warranty of CONE Gathering contained in this Agreement, (%3) any breach of any agreement or covenant contained in this Agreement on the part of CONE Gathering or (%3) any of the Excluded Liabilities.

8.3    Demands. Each indemnified party agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (such third party actions being collectively referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the indemnifying party, together with a statement of such information respecting any of the foregoing as it shall have. Such notice shall include a formal demand for indemnification under this Agreement. The indemnifying party shall not be obligated to indemnify the indemnified party with respect to any Indemnity Claim if the indemnified party knowingly failed to notify the indemnifying party thereof in accordance with the provisions of this Agreement to the extent that knowing failure to notify actually results in material prejudice or damage to the indemnifying party.

8.4    Right to Contest and Defend.

(a)    The indemnifying party shall be entitled at its cost and expense to contest and defend by all appropriate legal proceedings any Indemnity Claim with respect to which it is called upon to indemnify the indemnified party under the provisions of this Agreement; provided, however, that notice of the intention to so contest shall be delivered by the indemnifying party to the indemnified party within 20 days from the date of receipt by the indemnifying party of notice by the indemnified party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the indemnifying party or the indemnified party as may be appropriate. Such contest shall be conducted and prosecuted

diligently to a final conclusion or settled in accordance with this Section 8.4(a) by reputable counsel employed by the indemnifying party and not reasonably objected to by the indemnified party, but the indemnified party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense. The indemnifying party shall have full authority to determine all action to be taken with respect thereto; provided, however, that the indemnifying party will not have the authority to subject the indemnified party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense. If the indemnifying party does not elect to contest any such Indemnity Claim or elects to contest such Indemnity Claim but fails diligently and promptly to prosecute or settle such claim, the indemnifying party shall be bound by the result obtained with respect thereto by the indemnified party. If the indemnifying party shall have assumed the defense of an Indemnity Claim, the indemnified party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Indemnity Claim, which releases the indemnified party completely in connection with such Indemnity Claim and which would not otherwise adversely affect the indemnified party.

(b)    Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages.

8.5    Cooperation. If requested by the indemnifying party, the indemnified party agrees to cooperate with the indemnifying party and its counsel in contesting any Indemnity Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the Indemnity Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the indemnified party for any expenses incurred by it in so cooperating. At no cost or expense to the indemnified party, the indemnifying party shall cooperate with the indemnified party and its counsel in contesting any Indemnity Claim.

8.6    Right to Participate. The indemnified party agrees to afford the indemnifying party and its counsel the opportunity to be present at, and to participate in, conferences with all persons, including Governmental Authorities, asserting any Indemnity Claim against the indemnified party or conferences with representatives of or counsel for such persons.

8.7    Payment of Damages. The indemnification required hereunder shall be made by periodic payments of the amount thereof during the course of the investigation or defense, within 10 days as and when reasonably specific bills are received or loss, liability, claim, damage or expense is incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an indemnifying party by reason of the provisions of this Agreement, the amount shall be reduced by all reimbursements (including, without limitation, insurance proceeds) credited to or received by the other party related to the Damages.

8.8    Limitations on Indemnification.

(a)    To the extent the Partnership Indemnitees are entitled to indemnification for Damages pursuant to Section 8.2(a) (but not including Damages for breaches of Fundamental Representations), CONE Gathering shall not be liable for those Damages unless the aggregate amount of Damages exceeds $2,480,000 (the “Deductible”), and then only to the extent of any such excess; provided, however, that CONE Gathering shall not be liable for Damages pursuant to Section 8.2(a) (but not including Damages for breaches of Fundamental Representations) that exceed, in the aggregate, $37,200,000 (the “Cap”) less the Deductible.

(b)    Notwithstanding clause (a) above, to the extent the Partnership Indemnitees are entitled to indemnification for Damages for claims arising from fraud or related to or arising from Taxes, CONE Gathering shall be fully liable for such Damages without regard to the Deductible or the Cap.

(c)    To the extent the CONE Indemnitees are entitled to indemnification for Damages pursuant to Section 8.1(a), the Partnership Parties shall not be liable for those Damages unless the aggregate amount of Damages exceeds, in the aggregate, the Deductible, and then only to the extent of any such excess; provided, however, that the Partnership Parties shall not be liable for Damages that exceed, in the aggregate, the Cap less the Deductible.

(d)    Notwithstanding clause (c) above, to the extent the CONE Indemnitees are entitled to indemnification for Damages for claims arising from fraud, the Partnership Parties shall be fully liable for such Damages without regard to the Deductible or the Cap. For the avoidance of doubt, the Partnership Parties shall be fully liable for Damages pursuant to Section 8.1(b) or Section 8.1(c) without regard to the Deductible or the Cap.
