Section 5.3Tax Covenants.

(a)The Parties agree that the income related to the Subject Interests for the period up to and including the Closing Date will be reflected on the federal income Tax Return of NBL Midstream and that the members of NBL Midstream shall bear the liability for any Taxes associated with such income. The Parties further agree that the income related to the Subject Interests for the period after the Closing Date will be reflected on the federal income Tax Return of the Partnership and that the partners of the Partnership shall bear the liability for any Taxes associated with such income.

(b)The Parties shall cooperate fully, and cause their Affiliates to cooperate fully, as and to the extent reasonably requested by the other Party, to accomplish the purposes of this Section 5.3, requests for the provision of any information or documentation within the knowledge or possession of the other Party as reasonably necessary to facilitate compliance with financial reporting obligations arising under ASC 740 (formerly FASB Statement No. 109) (including

Such cooperation shall include access to, the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any Tax Return or Tax Proceeding, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Partnership and NBL Midstream will use their respective commercially reasonable efforts to retain all books and records with respect to Tax matters pertinent to the Subject Interests relating to any taxable period beginning before the Closing Date until the later of six years after the Closing Date or the expiration of the applicable statute of limitations of the respective taxable periods (including any extensions thereof), and to abide by all record retention agreements entered into with any Tax Authority. The Partnership and NBL Midstream each agree, upon request, to use their respective commercially reasonable efforts to obtain any certificate or other document from any Tax Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated by this Agreement.

(c)To the extent an election under Section 754 of the Internal Revenue Code of 1986, as amended (the “Code”) is not already in effect for each of Colorado River DevCo and Blanco River DevCo, the Parties shall provide all necessary consents (and evidence thereof) to cause the election provided by Code Section 754 in accordance with Treasury Regulation Section 1.754-1(b) to be made effective for the taxable period of each of Colorado River DevCo and Blanco River DevCo that includes the Closing Date.

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 NBL Midstream and its Affiliates, directors, officers, employees, agents and representatives (together with NBL Midstream, the “NBL 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

18

reasonable expenses of investigation, defending and prosecuting litigation (collectively, the “Damages”), suffered by the NBL Indemnitees as a result of, caused by, arising out of, or in any way relating to (a) any material breach of a representation or warranty of the Partnership Parties contained in this Agreement, (b) any material breach of any agreement or covenant contained in this Agreement on the part of the Partnership Parties or (c) any of the Assumed Liabilities.

Section 8.2Indemnification of the Partnership Parties. Solely for the purpose of indemnification in this Section 8.2, the representations and warranties of NBL Midstream in this Agreement 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, NBL Midstream shall indemnify and hold the Partnership Parties and their respective Affiliates, directors, officers, employees, agents and representatives, and the directors, officers, employees, agents and representatives of the General Partner (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 (a) any material breach of a representation or warranty of NBL Midstream contained in this Agreement or (b) any material breach of any agreement or covenant contained in this Agreement on the part of NBL Midstream.

Section 8.3Demands. 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.

Section 8.4Right 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

19

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.

Section 8.5Cooperation. 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 third party asserting the Indemnity Claim, or any cross-complaint against any third party, 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.

Section 8.6Right 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.

Section 8.7Payment 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. The Parties agree that any payment for indemnification

20

of Damages made hereunder will be treated as an adjustment to the Cash Consideration for U.S. federal income tax purposes.

(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, NBL Midstream shall be fully liable for such Damages without regard to the Deductible or the Cap.

The liability of the Partnership for Damages for claims related to or arising from Taxes shall be limited to claims for which NBL Midstream delivers written notice to the Partnership on or before the date that is 90 days after the expiration of the applicable statute of limitations for assessment of the applicable Tax.

After the Closing, no Party shall have liability under this Agreement or the transactions contemplated hereby except as is provided in this ARTICLE VIII (other than claims or causes of action arising from fraud, and other than claims for specific performance or claims arising under any Transaction Documents (which claims shall be subject to the liability provisions of such Transaction Documents)).
