(c)      The execution, delivery and performance of this Amendment by each Loan Party party hereto and the consummation of the transactions contemplated hereby will not (i) violate (A) any provision of law, statute, rule or regulation, (B) any order of or undertaking with any Governmental Authority or (C) any provision of any indenture, agreement or other instrument to which such Loan Party is a party or by which any of them or any of their property is bound, except such violation as could not reasonably be expected to have a Material Adverse Effect, (ii) result in the creation or imposition of (or the obligation to create or impose) any Lien upon or with respect to any property or assets now owned or hereafter acquired by such Loan Party or (iii) violate any provision of the certificate or articles of incorporation or certificate of formation or other constitutive documents or by-laws, partnership agreement or limited liability company agreement of such Loan Party.

(d)      The representations and warranties set forth in Article III of the Amended Credit Agreement and in each other Loan Document are true and correct in all material respects on and as of the Second Amendment Effective Date with the same effect as though made on and as of such date, except to the extent such representations and warranties expressly relate to an earlier date, in which case they were true and correct in all material respects as of such earlier date; provided , that any representation and warranty that is qualified as to “materiality,” “Material Adverse Effect” or similar language is true and correct (after giving effect to any qualification contained therein) in all respects.

(e)      On and immediately after the Second Amendment Effective Date, no Default or Event of Default has occurred and is continuing.

SECTION 8      . Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. The terms of Section 9.07, 9.11 and 9.15 of the Credit Agreement are incorporated herein by reference, mutatis mutandis , and the parties hereto agree to such terms.
