Notwithstanding the foregoing, it is the intention of the Borrower and the Lenders, and the Borrower and the Lenders agree and acknowledge, that any reduction in the Revolving Commitments as a result of the incurrence of Second Lien Debt or Third Lien Debt permitted by clause (ii) or (iii) of Section 7.01(h) shall not result in, or be construed as, a permanent reduction in the borrowing capacity of the Borrower and its Restricted Subsidiaries; provided that, any increases in the borrowing capacity of the Borrower and its Restricted Subsidiaries hereunder shall be subject to the terms and conditions in this Agreement (including Section 2.03, Article III and Section 11.02(b)(i)-(ii)).
