Now Therefore, in consideration of the premises and the mutual agreements set forth herein, the Borrower, the Required Lenders, the Issuing Lender and the Administrative Agent agree as follows:

No Requirement of Law or Contractual Obligation applicable to the Borrower or any of its Subsidiaries could reasonably be expected to have a Material Adverse Effect.
