Fourth Amendment Effective Date, each of the Parent and Legacy GP hereby becomes a party to this Agreement with the same force and effect as if originally named herein and hereby agrees to be bound by the terms of this Agreement. In
furtherance of the foregoing, on the Fourth Amendment Effective Date, each of the Parent and Legacy GP shall execute and deliver to the Administrative Agent a joinder with respect to its obligations under this Agreement, which shall be in form and
substance reasonably satisfactory to the Administrative Agent and Majority Lenders. Each of the Parent and Legacy GP hereby represents and warrants that each of the representations and warranties applicable to it in this Agreement are true and
correct, except to the extent any such representations and warranties are expressly limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct as of such specified earlier date. 

  
 Page 16 









 Section 3. Consent to Reorganization Transactions. 

3.1 So long as the Fourth Amendment Effective Date has occurred by December 31, 2018 (as may be extended with the consent of the Majority
Lenders), the Lenders hereby (a) agree that (i) none of the Reorganization Transactions shall constitute (A) a merger or consolidation in violation of Section 9.11 or (B) a transaction with an Affiliate in violation of
Section 9.14 and (ii) the Change in Control that results on account of the Reorganization Transactions is hereby waived in its entirety and is deemed not to have occurred and (b) consent to the Borrower’s payment of cash in lieu
of fractional shares held by its limited partner Equity Interest holders pursuant to the terms of the Merger Agreement in an amount up to $50,000 (or such greater amount as the Majority Lenders
may agree to in their sole discretion) and the Borrower’s payment to Parent of the cash consideration to be paid by Parent to the equityholders of Legacy GP pursuant to the GP Purchase Agreement in an amount up to $3,500,000 (or such greater
amount as the Majority Lenders may agree to in their sole discretion). 
 3.2 Except as expressly waived herein, all covenants, obligations
and agreements of the Borrower and each Guarantor contained in the Term Loan Credit Agreement (as amended hereby) and the other Term Loan Documents shall remain in full force and effect in accordance with their terms. Without limitation of the
foregoing, the foregoing waiver is hereby granted to the extent and only to the extent specifically stated herein and for no other purpose and shall not be deemed to (a) be a consent or agreement to, or waiver or modification of, or amendment
to, any other term or condition of the Term Loan Credit Agreement (as amended hereby), any other Term Loan Document or any of the documents referred to therein, (b) except as expressly set forth herein, prejudice any right or rights which the
Administrative Agent or the Lenders may now have or may have in the future under or in connection with the Term Loan Credit Agreement (as amended hereby), any other Term Loan Document or any of the documents referred to therein, or
(c) constitute any course of dealing or other basis for altering any obligation of the Borrower or any right, privilege or remedy of the Administrative Agent or the Lenders under the Term Loan Credit Agreement (as amended hereby), the other
Term Loan Documents, or any other contract or instrument. Granting the waiver set forth herein does not and should not be construed to be an assurance or promise that consents or waivers will be granted in the future, whether for the matters herein
stated or on other unrelated matters. 
 Section 4. Waiver to Term Loan Credit Agreement. 

4.1 Waiver of Section 3.04(c)(i). The obligation of the Borrower to comply with the requirements of
Section 3.04(c)(i) is hereby waived such that the first quarter with respect to which the Borrower’s ratio of First Lien Debt to EBITDA is tested for purposes of Section 3.04(c)(i) shall be the quarter ending March 31, 2019.

entitled to vote on the matter; (d) that the consummation of the Reorganization Transactions will not violate or result in a default under any indenture, agreement, preferred stock designation or other instrument binding upon the Borrower or

of its Subsidiaries; (e) that the Reorganization Transactions have been consummated (or will be consummated substantially simultaneously with the Fourth Amendment Effective Date) pursuant to the terms and conditions set forth in the Merger
