“Second Lien Notes” means senior secured second lien notes issued by the Borrower under a Second Lien
Indenture, which Debt is intended to be secured on a junior basis by any collateral securing the Obligations, provided that such Debt is permitted to be incurred and remain outstanding hereunder pursuant to Section 9.02(k) and any Liens

 (ix) at the
time of the incurrence of such Debt, such Debt and any guarantees thereof are on terms, taken as a whole, not materially less favorable to the Borrower and its Subsidiaries as market terms for issuers of similar size and credit quality given the

the incurrence of any such Lien, the Borrower is in compliance with Section 8.14(e); and
