Subject to Section 4.3 [Interest After Default], (a) only the Daily LIBOR Rate, plus the Applicable Margin for LIBOR Rate Loans, shall apply to the Domestic Swing Loans, provided that, at the option of the Domestic Swing Loan Lender, upon notice from the Domestic Swing Loan Lender to the Parent, the Domestic Swing Loans shall bear interest at the Base Rate, plus the Applicable Margin for Base Rate Loans, if the Domestic Swing Loan Lender determines that any of the events or conditions described in Section 4.4.1 or Section 4.4.2 applies to the Published Rate (for the purposes of this sentence only, with references in such Sections to “LIBOR Rate” and “LIBOR Rate Option” being deemed to refer to the Published Rate); (b) and only the Overnight Rate, plus the Applicable Margin for LIBOR Rate Loans, shall apply to the Foreign Swing Loans.
2.    First Amendment Effective Date; Conditions Precedent; Certifications.

(i)    The Borrowers, the Guarantors and the Administrative Agent shall have executed and delivered this First Amendment;
(ii)    The certifications of the Borrowers and the Guarantors contained in clauses (i), (ii) and (iii) of paragraph (B), below, shall be true and correct in all material respects as of such date, and the Borrowers shall be deemed to have restated each of them as of the First Amendment Effective Date; and
