the rate that may now be lawfully contracted for in writing in the State of

         No delay on the part of the Lender or any holder hereof in exercising
any right or remedy hereunder shall operate as a waiver of or preclude the
exercise of such right or remedy or of any other remedy under this Note. No
waiver by the Lender or any holder hereof shall be effective unless in writing
signed by such holder. A waiver on any one occasion shall not be construed as a
