ARTICLE 3
INITIAL TRUE-UP

3.1                               Initial True-Up.  Each of the Contributors shall account to one another in cash within ninety (90) days of Closing as appropriate to the extent the Adjusted Enterprise Value of the Company is greater or less than the Final Adjusted Enterprise Value of the Company. Notwithstanding anything in this Section 3.1 to the contrary, calculations pursuant to this Section 3.1 shall not take into account any exercise of the overallotment option in connection with the IPO.  For illustrative purposes only, Schedule 3.1 includes examples of the calculations to be conducted in accordance with this Section 3.1.

3.2                               Interim Period True-Up.  Each of the contributors shall be entitled to his or its share of revenue from the oil and gas properties in which both OpCo and any of the Contributors owns a working interest (collectively, the “Commonly Owned Properties”), and shall be responsible for his or its share of the costs attributable thereto, in each case until 7:00 a.m. (Central time) on the day of Closing

(a)                                 Within ninety (90) days after the Closing, the Contributors shall account to one another in cash as set forth in this Section 3.2 with respect to revenues and expenses (including capital expenditures) attributable to the interests of the Contributors in the Commonly Owned Properties and other oil and gas properties directly or indirectly included in the Asset Exchanges (collectively the “Asset Exchange Properties”) during the period commencing at 7:00 a.m. (Central time) on October 1, 2013, and ending at the Asset Exchange Effective Time (the “Interim Period”).

(b)                                 For illustrative purposes only, Schedule 3.2 includes examples of the calculations to be conducted in accordance with this Section 3.2.  In the event that any Contributor’s Actual Interim Period Net Income is greater than such Contributor’s Allocated Interim Period Net Income, such Contributor shall be obligated to make payments equal to the amount of the difference to the other Contributors whose Allocated Interim Period Net Income exceeds their Actual Interim Period Net Income. Conversely, in the event that a Contributor’s Actual Interim Period Net Income is less than such Contributor’s respective Allocated Interim Period Net Income, such Contributor shall be entitled to receive payments equal to the amount of the difference from those other Contributors, as applicable, whose Allocated Interim Period Net Income is less than their Actual Interim Period Net Income.  The intent of the foregoing accounting is to place each Contributor in the position, on a before Tax basis, such Contributor would have been had such Contributor received his or its Allocated Interim Period Net Income instead of his or its Actual Interim Period Net Income.  For purposes of this Section 3.2(b) only, the interests of OpCo in the Commonly Owned Properties and the Asset Exchange Properties shall be deemed to be the interests of Holdco in the Commonly Owned Properties and the Asset Exchange Properties through the Asset Exchange Effective Time.

(c)                                  The provisions of this Section 3.2 shall not modify any Contributor’s (i) entitlement to revenue included in his or its Actual Interim Period Net Income or to credit from the Company for any pre-paid expenses attributable to his or its interests in the Asset Exchange Properties as of the Asset Exchange Effective Time or (ii) responsibility for costs or expenses

5

(including capital expenditures, severance Taxes and ad valorem Taxes, prorated as appropriate) included in his or its Actual Interim Period Net Income or for accounts payable attributable to his or its interest in the Asset Exchange Properties as of the Asset Exchange Effective Time. It is understood that HoldCo shall be responsible for any post-IPO accounting with ACTOIL, LLC (“ACTOIL”) in accordance with that certain letter agreement dated November 13, 2013, between OpCo and ACTOIL (the “ACTOIL Letter Agreement”).

(d)                                 For the avoidance of doubt, the true-ups described in Sections 3.1 and 3.2 are between the Contributors, and accordingly neither the Company nor OpCo will pay or have any obligation to pay any cash or other consideration, or any right to receive any cash or other consideration in respect of such true-ups.

3.3                               Indemnity Escrow.  Notwithstanding anything in this Agreement to the contrary, it is understood that (a) OpCo’s rights with respect to the Indemnity Escrow (as defined in the Purchase, Sale and Option Agreement dated December 28, 2012, among Resolute Natural Resources, LLC, OpCo, Collins and Wallace LP) will not be held by the Company but will be held by and distributed to HoldCo, and HoldCo will be responsible for accounting to ACTOIL, as provided in Section 3 of the ACTOIL Letter Agreement, (b) Collins and Wallace LP will retain their respective rights with respect to the Indemnity Escrow, and (c) the Indemnity Escrow shall not be considered in the calculation of Adjusted Enterprise Value or the Final Adjusted Enterprise Value.
