Section 1. Defined Terms; Interpretation. As used in this Agreement, each of the terms defined in the opening paragraph and

to the contrary. The words “hereby”, “herein”, “hereinafter”, “hereof”, “hereto” and “hereunder” when used in this Agreement shall refer to this Agreement as a whole and not to any
particular Article, Section, subsection or provision of this Agreement. Article, Section, subsection and Exhibit references herein are to such Articles, Sections, subsections and Exhibits of this Agreement unless otherwise specified. All titles or
headings to Articles, Sections, subsections or other divisions of this Agreement or the exhibits hereto, if any, are only for the convenience of the parties and shall not be construed to have any effect or meaning with respect to the other content
of such Articles, Sections, subsections, other divisions or exhibits, such other content being controlling as the agreement among the parties hereto. Whenever the context requires, reference herein made to the single number shall be understood to
include the plural; and likewise, the plural shall be understood to include the singular. Words denoting sex shall be construed to include the masculine, feminine and neuter, when such construction is appropriate; and specific enumeration shall not
exclude the general but shall be construed as cumulative. Definitions of terms defined in the singular or plural shall be equally applicable to the plural or singular, as the case may be, unless otherwise indicated.

Documents; provided that (a) the Borrower 






 
may at any time pay scheduled interest under the Second Lien Note Documents and pay costs and expenses incurred under the Second Lien Note Documents, and (b) the Borrower may exchange

(which may be provided by e-mail) of the detailed terms of such exchange (which detailed terms may be consistent with such information provided in the Borrower’s public filings) promptly after the consummation of such exchange. 

Section 3. Representations and Warranties. Each Loan Party represents and warrants that: (a) after giving effect to
this Agreement, the representations and warranties contained in the Credit Agreement and the representations and warranties contained in the other Loan Documents are true and correct in all material respects (except that such materiality qualifier

the Second Lien Loan Documents.

terms or conditions contained in any of the Loan Documents, (iii) any rights or remedies of the Administrative Agent, the Collateral Agent, the Issuing Lender, the Swing Line Lender, or any Lender with respect to the Loan Documents, or

Loan Documents as amended prior hereto as described in the recitals, and by this Agreement. 
 (e) This Agreement is a Loan Document for the
purposes of the provisions of the other Loan Documents. Without limiting the foregoing, any breach of representations, warranties, and covenants under this Agreement shall be a Default or Event of Default, as applicable, under the Credit Agreement.

 Section 6. Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an
