most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production; provided that in the event that the Mortgaged Properties do not represent at least 95% of such

end thereof: 
 For the avoidance of doubt, a single-step merger in which the Borrower merges with and into a newly-formed

and any other information related thereto reasonably requested by the Administrative Agent or any Lender; (B) the survivor of the Conversion Transaction (the “Successor Borrower”) shall be organized under the laws of a state of

information that may be required by such Lender in order to enable compliance with applicable “know your customer” and anti-money laundering rules and regulations, including information required by the Patriot Act; (D) the Successor
Borrower shall expressly assume all obligations under this Agreement and the other Loan Documents, and each mortgagor, pledgor, grantor, guarantor or other obligor under the Loan Documents shall expressly ratify and confirm its obligations under the
Loan Documents, in each case, pursuant to documentation in form and substance satisfactory to the Administrative Agent; (E) the Administrative Agent shall have received such other agreements (including amendments or amendments and restatements

under the Loan Documents, and the assumption, confirmation and ratification of all obligations of the Successor Borrower and the other obligors under the Loan Documents; (F) both before and after giving effect thereto, no Borrowing Base
Deficiency, Default or Event of Default exists or would result therefrom; (G) the Successor Borrower shall be in pro forma compliance with each of the covenants set forth in Section 9.01; (H) the Conversion Transaction is not materially
adverse to the Lenders (for purposes of this clause (H) the Conversion Transaction will not be considered materially adverse to the Lenders solely because the Successor Borrower (1) is subject to federal or state income taxation as an
entity or (2) is considered to be an “includible corporation” of an affiliated group of corporations within the meaning of Section 1504(b) of the Code or any similar state or local law); (I) the Conversion Transaction
(w) does not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority or any other third Person (including any class of directors of the general partner of the Borrower, whether
interested or disinterested, or any holders of the Equity Interests in the Borrower), except such as have been obtained or made and are in full force and effect, (x) will not violate any applicable law or regulation, or the charter, by-laws or other organizational documents of the Borrower or any of its Subsidiaries, or any order of any Governmental Authority, (y) will not violate or result in a default under any indenture, agreement or
other instrument binding upon the Borrower or any of its Subsidiaries or their Properties, or give rise to a right thereunder to require any payment to be made by the Borrower or such Subsidiary and (z) will not result in the creation or
imposition of any Lien on any Property of the Borrower or any of its Subsidiaries; and (J) the Borrower shall deliver to the Administrative Agent a certificate of a Responsible Officer of the Borrower certifying as to the satisfaction of the
conditions and matters set forth in clauses (A)-(I) above (and in the case of clause (G) above, setting forth reasonably detailed calculations 

  
 Page 25 









 demonstrating pro forma compliance with the covenants set forth in Section 9.01).
Notwithstanding the foregoing, in no event shall the Conversion Transaction be permitted if the Administrative Agent determines in its sole discretion that the Conversion Transaction would adversely affect or impair in any respect the validity,
perfection or priority of any Lien on any Property securing all or any portion of the Indebtedness. 
 2.23 Amendment to
Section 9.12(b). Section 9.12(b) is hereby amended and restated in its entirety to read as follows:

of the Borrower) (each, an “Affiliate Transaction”) unless (a) such transactions are otherwise permitted under this Agreement and are upon fair and reasonable terms no less favorable to it than it would obtain in a comparable
arm’s length transaction with a Person not an Affiliate and (b) the Borrower delivers to the Administrative Agent and Lenders: (i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $25.0 million but less than or equal to $50.0 million, an officers’ certificate of a Responsible Officer certifying that such Affiliate Transaction or series of related Affiliate Transactions
complies with this Section 9.14; or (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, an officers’ certificate of a
Responsible Officer certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 9.14 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by
either the conflicts committee of the board of directors of the general partner of the Borrower (or the board of directors of the Borrower to the extent the Borrower ceases to have a general partner) (so long as the members of the conflicts
committee approving the Affiliate Transaction or series of related Affiliate Transactions are disinterested) or a majority of the disinterested members of the board of directors of the general partner of the Borrower (or the board of directors of
the Borrower to the extent the Borrower ceases to have a general partner) pursuant to a resolution set forth in such officers’ certificates.
