Agent and Lenders have granted the foregoing waiver in this particular instance and in light of the facts and circumstances that presently exist, and the grant of such waiver shall not constitute a course of dealing or impair Agent or any Lender’s right to withhold a waiver or any Defaults or Events of Default in the future.
