(ii)The execution, delivery and performance of each of the Amendment Documents in accordance with its terms do not and will not, by the passage of time, the giving of notice, or both: (i) require any Governmental Approval or violate any Applicable Law (including Environmental Laws) relating to the Borrower or Parent; (ii) conflict with, result in a breach of or constitute a default under the organizational documents of the Borrower or Parent, or any indenture, agreement or other instrument to which the Borrower or Parent is a party or by which it or any of its respective properties may be bound; or (iii) result in or require the creation or imposition of any Lien upon or with respect to any property now owned or hereafter acquired by the Borrower or Parent;

(iii)the representations and warranties of the Parent and the Borrower contained in Article VI of the Loan Agreement are and will be true and correct in all material respects (or, in the case of any such representation or warranty already qualified by materiality, in all respects) on and as of the date hereof and the Amendment Effective Date to the same extent as though made on and as of such dates, except to the extent such representations and warranties specifically relate to an earlier date, in which case they were true and correct in all material respects (or, in the case of any such representation or warranty already qualified by materiality, in all respects) on and as of such earlier date and except for changes in factual circumstances not prohibited by the Loan Agreement; and

(iv)no event has occurred and is continuing or will result from the consummation of the transactions contemplated by this Amendment No. 1 that would constitute a Default or Event of Default.
