warranties shall have been true and correct in all material respects on and as of such earlier date; provided that, in each case, such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and

b) As of the Amendment No. 1 Effective Date, no event has occurred and is continuing that would constitute a Default or an Event of Default.
