PURCHASE PRICE ADJUSTMENTS 

5.1 Closing Adjustments. With respect to matters that can be determined as of the Closing, Seller shall prepare, in accordance with the
provisions of this Section 5.1, a statement (the “Closing Adjustment Statement”) with relevant supporting information setting forth each adjustment to the Base Purchase Price contemplated by Sections
3.3(a) and 3.3(b). Seller shall submit the Closing Adjustment Statement to Buyer, together with appropriate data supporting the calculation of amounts presented on the Closing Adjustment Statement, no later than three (3) business
days prior to the scheduled Closing Date. When available, actual figures will be used for the adjustments at Closing. To the extent actual figures are not available, estimates shall be used subject to final adjustments as described in
Section 5.3 below. Prior to the Closing, Buyer and Seller shall review the adjustments proposed by Seller in the Closing Adjustment Statement. Agreed upon adjustments shall be taken into account in computing adjustments to
be made to the Base Purchase Price at the Closing. If Buyer and Seller do not agree upon any given proposed adjustments, the amounts in dispute shall be deferred to the final adjustments as described in Section 5.3, and the
amount of any such adjustments as proposed by Seller shall be used for purposes of computing adjustments to be made to the Base Purchase Price at the Closing. 

  
 21 

 5.2 Strapping and Gauging. Seller has caused (or will cause) the Hydrocarbons in the
storage facilities located on, or utilized in connection with, the Leases to be measured, gauged or strapped as of the Effective Time. Seller has caused the production meter charts (or if such do not exist, the sales meter charts) on the pipelines
transporting Hydrocarbons from the Leases to be read as of such time. The marketable Hydrocarbons in such storage facilities above the pipeline connection or through the meters on the pipelines prior to the Effective Time shall belong to Seller, and
the Hydrocarbons delivered to such storage facilities upstream of the aforesaid meters from and after the Effective Time shall belong to Buyer and be included in the Assets. 

5.3 Post-Closing Adjustments. 

(a) A post-closing adjustment statement (the “Post-Closing Adjustment Statement”) based on the actual figures and reflecting
the adjustments to the Base Purchase Price contemplated in Sections 3.3(a) and 3.3(b) shall be prepared and delivered by Seller to Buyer within one hundred twenty (120) days after the Closing, proposing final adjustments to the
calculation of the Purchase Price based on the information then available. Seller or Buyer, as the case may be, shall be given reasonable access to and shall be entitled to a review and audit during normal business hours of the other Party’s
records pertaining to the computation of amounts claimed in the Post-Closing Adjustment Statement. In the preparation of the Post-Closing Adjustment Statement, Seller shall take into account Section 5.6. 

(b) Within sixty (60) days after receipt of the Post-Closing Adjustment Statement, Buyer shall deliver to Seller a written statement
describing in reasonable detail its objections (if any) to any amounts or items set forth on or omitted from the Post-Closing Adjustment Statement. If Buyer does not raise any objections within such period, then the Post-Closing Adjustment Statement
shall become final and binding upon the Parties at the end of such period. 
 (c) If Buyer raises any objections to the Post-Closing
Adjustment Statement, the Parties shall negotiate in good faith to resolve any such objections. If the Parties are unable to resolve any disputed item, then within thirty (30) days after Seller’s receipt of Buyer’s written objections
to the Post-Closing Adjustment Statement, any such disputed item shall be submitted to KPMG US LLP, or such other Person as the Parties may mutually select. The resolution of disputes by the accounting firm so selected shall be set forth in writing
and shall be conclusive, binding and non-appealable upon the Parties and the Post-Closing Adjustment Statement shall become final and binding upon the Parties on the date of such resolution. The fees and
expenses of such accounting firm shall be paid one-half by Buyer and one-half by Seller. 

(d) Within five (5) days after the Post-Closing Adjustment Statement has become final and binding on the Parties, Seller or Buyer, as the
case may be, shall pay to the other such sums as are due to settle accounts between the Parties due to differences between the estimated Purchase Price paid at the Closing pursuant to the Closing Adjustment Statement and the actual Purchase Price
set forth on the Post-Closing Adjustment Statement. 
 5.4 Suspended Funds. At the Closing, Seller shall provide to Buyer a listing
showing all proceeds from production attributable to the Leases which are currently held in suspense and any interest payable thereon (“Suspense Funds”) and, to the extent Seller is able to identify the reasons therefor, a statement
of such reasons and the applicable records pertaining thereto and shall transfer to Buyer all of those suspended proceeds. Based on such information received from Seller, Buyer shall distribute such suspended proceeds that it receives from Seller
but shall have no further liability for funds suspended by Seller. 

  
 22 

 5.5 Audit Adjustments. Except to the extent relating to any Buyer Liabilities and
except for which an upward adjustment has been made to the Purchase Price (i) Seller retains all rights to adjustments resulting from any operating agreement and other audit claims asserted against third-party operators on transactions
occurring prior to the Effective Time (which includes Buyer, if applicable), and (ii) any credit received by Buyer pertaining to such an audit claim shall be paid to Seller within thirty (30) days after receipt. 

5.6 Asset Taxes. 
 (a)
Proration. Subject to the provisions of Section 5.6(b) below, all Asset Taxes with respect to the Assets, other than such Taxes which are Buyer Liabilities, shall be prorated between Seller and Buyer as of the
Effective Time on the Closing Adjustment Statement and on the Post-Closing Adjustment Statement. On such settlement statements, Seller will be responsible for Asset Taxes attributable to time periods prior to the Effective Time and Buyer will be
responsible for Asset Taxes for time periods on and after the Effective Time. 
 (b) Liability of Buyer. Asset Taxes attributable to
periods of time prior to the Effective Time, to the extent not actually assessed or otherwise determined as of the date of Closing (for purposes of the Closing Adjustment Statement) and as of the date of the Post-Closing Adjustment Statement (for
purposes of the Post-Closing Adjustment Statement), shall be computed based on each applicable Tax for the preceding tax year and prorated between Seller and Buyer as of the Effective Time on the Closing Adjustment Statement and prorated and
readjusted as appropriate on the Post-Closing Adjustment Statement in accordance with such calculation methodology and any additional assessment, determination or corrective information received as of the date of the Post-Closing Adjustment
Statement. 
 (c) Refunds of Asset Taxes paid (or to the extent payable but not paid due to offset against other Taxes) with respect to or
attributable to the Assets shall be diligently pursued and promptly paid by the Party receiving the benefit of the payment or offset as follows: (a) except to the extent relating to any Buyer Liabilities and except for which an upward
adjustment has been made to the Purchase Price, to Seller if attributable to Asset Taxes with respect to any Tax year or portion thereof ending on or before the Effective Time; and (b) except to the extent relating to any Retained Liabilities
or any Non-Asset Liabilities and except for which a downward adjustment has been made to the Purchase Price, to Buyer if attributable to Asset Taxes with respect to any Tax year or portion thereof beginning
from and after the Effective Time. 
 5.7 Cooperation. Each Party covenants and agrees to cooperate in all reasonable respects in the
pursuit and payment of amounts referred to in Sections 5.3, 5.5 and 5.6.

Well throughout the productive life of such Well, except (x) as stated in such Schedule; and (y) as such Net Revenue Interest may be reduced from time to time due to: (A) the establishment after the date of this Agreement of units, or

under applicable operating agreements; or (C) the entry into of pooling, spacing, proration, communitization, unitization, or similar agreements after the date of this Agreement;

of the Working Interest in such Well through the plugging and abandonment of such Well, except (x) as stated in such Schedule; and (y)

therein) after the date of this Agreement, whether voluntary or by Order; (B) the exercise after the date of this Agreement of non-consent rights under applicable operating agreements; or (C) the

terms hereof, each Indemnified Party shall make reasonable efforts to mitigate or minimize all Liabilities upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Liabilities that are
indemnifiable hereunder. 
 15.5 Notification. As soon as reasonably practical after obtaining knowledge thereof, any Party seeking
indemnification under this Agreement (the “Indemnified Party”) shall notify the other Party (the “Indemnifying Party”) of any Claim or Proceeding which the Indemnified Party has determined has given or could give
rise to a claim for indemnification under this ARTICLE XV. Such notice shall specify the agreement, representation or warranty with respect to which the claim is made, the facts giving rise to the claim and the amount (to the extent then
determinable) of liability for which indemnity is asserted. In the event any action, suit or proceeding is brought with respect to which a Party may be liable under this ARTICLE XV, the defense of the action, suit or proceeding (including all
settlement negotiations and arbitration, trial, appeal or other proceeding) shall be at the discretion of and conducted by the Indemnifying Party. If an Indemnified Party shall settle any such action, suit or proceeding without the written consent
of the Indemnifying Party (which consent shall not be unreasonably withheld), the right of the Indemnified Party to make any claim against the Indemnifying Party on account of such settlement shall be deemed conclusively denied. An Indemnified Party
shall have the right to be represented by its own counsel at its own expense in any such action, suit or proceeding, and if an Indemnified Party is named as the defendant in any action, suit or proceeding, it shall be entitled to have its own
counsel and defend such action, suit or proceeding with respect to itself at its own expense. Subject to the foregoing provisions of this ARTICLE XV, neither Party shall, without the other Party’s written consent, settle, compromise,
confess judgment or permit judgment by default in any action, suit or proceeding if such action would create or attach any liability or obligation to the other Party. The Parties agree to make available to each other, and to their respective counsel
and accountants, all information and documents reasonably available to them which relate to any action, suit or proceeding, and the Parties agree to render to each other such assistance as they may reasonably require of each other in order to ensure
the proper and adequate defense of any such action, suit or proceeding, including entering into a joint defense privilege agreement.

full satisfaction for all or any alleged injuries or damages arising in connection with the Released Matters herein compromised and settled. Each Loan Party hereby further agrees that it will not sue any Released Party on the basis of any Released

insolvency or similar proceeding involving the Borrower, any Guarantor, or otherwise, the indebtedness intended to be repaid thereby shall be reinstated (without any further action by any party) and shall be enforceable against the Borrower and the
Guarantors. In such event, the Borrower and the Guarantors shall be and remain liable to such Secured Party for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Secured Party.
