modified in any material respect without the approval of the Administrative Agent (such approval not to be unreasonably withheld, conditioned or delayed; provided, that, for the avoidance of doubt, it shall be reasonable for the Administrative Agent
to withhold its consent to any such waiver or amendment that removes any Oil and Gas Properties (other than a waiver or amendment which removes up to $2,000,000 of Oil and Gas Properties (as determined by the Administrative Agent) from the WHT
Assets)); and (ii) as to the final purchase price for the Equity Interests in WHT Energy Partners after giving effect to all adjustments as of the WHT Acquisition Closing Date and specifying, by category, the amount of such adjustment;
(b) original counterparts or copies, certified as true and complete by a Responsible Officer of the Borrower, of each of the WHT Acquisition Documents not previously delivered and certified to the Administrative Agent, which WHT Acquisition

the most recent Reserve Report (as supplemented by any applicable Reserve Reports relating to the WHT Assets) and (B) the Mortgaged Properties shall represent at least 80% of the total value of the Oil and Gas Properties evaluated in the most

Agreement as necessary pursuant to which (i) each WHT Entity becomes a Guarantor, (ii) each WHT Entity grants to the Administrative Agent a perfected, first-priority security interest in substantially all of the material tangible and
intangible personal property assets owned by it, (iii) the Loan Parties grant to the Administrative Agent a perfected, first-priority security interest in the Equity Interests in each WHT Entity owned by each such Loan Party, (b) evidence

Applicable Percentage (after giving effect to this Section 7.1), (c) such other adjustments shall be made as the Administrative Agent shall specify so that the Revolving Credit Exposure applicable to each Lender equals its
Applicable Percentage (after giving effect to this Section 7.1) of the aggregate Revolving Credit Exposure of all Lenders and (d) the Borrower shall be required to make any break-funding payments required under Section 5.02 of
the Credit Agreement resulting from the Loans and adjustments described in this Section 7.1.

agent on its behalf and to exercise such powers and discretion under the Credit Agreement as amended hereby as are delegated to the Administrative Agent by the terms thereof, together with such powers and discretion as are reasonably incidental
thereto. Each New Lender represents and warrants that (a) it has full power and authority, and has taken all action necessary, to execute and deliver this Fifth Amendment, to consummate the transactions contemplated hereby and to become a party
to, and a Lender under, the Credit Agreement as amended hereby, (b) it has received a copy of the Credit Agreement and copies of the most recent financial statements delivered pursuant to Section 8.01 thereof, and such other documents and

Administrative Agent or any other Lender, and (c) from and after the Fifth 

  
 Page 14








 
Amendment Effective Date, it shall be a party to and be bound by the provisions of the Credit Agreement as amended hereby and the other Loan Documents and have the rights and obligations of a
Lender thereunder. If the WHT Acquisition Closing Date does not occur, and the conditions set forth in Section 5 hereof are not satisfied, in each case, on or prior to April 30, 2013, any New Lender with a Maximum Credit Amount of
$0.00 shall automatically cease to be a Lender for all purposes under the Credit Agreement and the other Loan Documents as of May 1, 2013. 
 Section 9. Second Lien Intercreditor Agreement. Each Lender hereby consents to the terms of, and authorizes the Administrative Agent to enter into in the event that the Borrower incurs
Permitted Second Lien Debt, a form of Intercreditor Agreement with respect to the Permitted Second Lien Debt that is substantially in the form attached hereto as Exhibit B, and each Lender agrees that the terms of such Intercreditor Agreement
shall be binding on such Lender and its successors and assigns, as if it were a party thereto. 
 Section 10.
Representations and Warranties; Etc. Each Loan Party hereby affirms: (a) that as of the date hereof, all of the representations and warranties contained in each Loan Document to which such Loan Party is a party are true and correct in
all material respects as though made on and as of the date hereof (unless made as of a specific earlier date, in which case, was true as of such date), (b) no Defaults exist under the Loan Documents or will, after giving effect to this Fifth
Amendment, exist under the Loan Documents and (c) no Material Adverse Effect has occurred. 
 Section 11.
Miscellaneous. 
 11.1 Confirmation and Effect. The provisions of the Credit Agreement (as amended by this Fifth
Amendment) shall remain in full force and effect in accordance with its terms following the effectiveness of this Fifth Amendment. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof’,

is a party, as amended hereby, (c) acknowledges, renews and extends its continued liability under the Guaranty Agreement and the other Loan Documents to which it is a party, as amended hereby and (d) agrees that its guarantee under the

other documents prepared in connection herewith and the transactions contemplated hereby, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent. 

11.7 Severability. Any provision of this Fifth Amendment which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.
