parties hereto relating to the subject matter hereof and thereof and supersede
any and all previous agreements and understandings, oral or written, relating to
the subject matter hereof and thereof. This Fourth Amendment, the Credit
Agreement and the other Loan Documents represent the final agreement among the
parties hereto and thereto and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
