Re: Extension of Standstill Period

Dear Mr. McDavid:

Reference is made to: (i) the Third Amended and Restated Credit Agreement, dated as of September 1, 2016 (as amended, restated, supplemented or otherwise modified from time to time, the “First Lien Credit Agreement”), by and among Titan Energy Operating, LLC, as borrower (the “Borrower”), Titan Energy, LLC, as parent (the “Parent”), the lenders party thereto from time to time and Wells Fargo Bank, National Association, as administrative agent (in such capacity, the “First Lien Administrative Agent”); (ii) the Amended and Restated Second Lien Credit Agreement, dated as of September 1, 2016 (as amended, restated, supplemented or otherwise modified from time to time, the “Second Lien Credit Agreement”), by and among the Borrower, the Parent, the lenders party thereto from time to time and Wilmington Trust, National Association, as administrative agent (in such capacity, the “Second Lien Administrative Agent”); (iii) the Amended and Restated Intercreditor Agreement, dated as of September 1, 2016 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”), by and among the Borrower, the Parent, each of the other guarantors party thereto, Wells Fargo Bank, National Association, as first lien collateral agent (in such capacity, the “First Lien Collateral Agent”), and Wilmington Trust, National Association, as second lien collateral agent (in such capacity, the “Second Lien Collateral Agent”); and (iv) the Notice of Events of Default under the Credit Agreement & Reservation of Rights letter, dated April 21, 2017 (the “Notice of Default”), by the Second Lien Administrative Agent to the First Lien Administrative Agent. Capitalized terms used in this letter but not otherwise defined herein have the meanings given to such terms in the Intercreditor Agreement.

On April 21, 2017, the Second Lien Administrative Agent delivered the Notice of Default to the First Lien Administrative Agent. Upon delivery of the Notice of Default, pursuant to Section 3.02(a)(i) of the Intercreditor Agreement, a Standstill Period commenced (such Standstill Period, the “Specified Standstill Period”). The Specified Standstill Period is scheduled to expire on October 18, 2017.

In order to provide the First Lien Lenders, Second Lien Lenders and the Loan Parties additional time to negotiate the terms of proposed amendments to each of the First Lien Credit Agreement and the Second Lien Credit Agreement, the Second Lien Collateral Agent hereby agrees to extend the Specified Standstill Period by an additional 35 days to November 22, 2017.

The provisions of the First Lien Credit Agreement, the Second Lien Credit Agreement and the Intercreditor Agreement shall remain in full force and effect in accordance with their terms following the effectiveness of this letter agreement (this “Extension Letter”), and this Extension Letter shall not constitute a waiver of any provision of the First Lien Credit Agreement, the Second Lien Credit Agreement, the Intercreditor Agreement or any other First Lien Loan Document or Second Lien Loan Documents or Notice of Default, except as expressly provided for herein.
