be effective only if in a writing signed by the party or parties against which
such waiver is to be asserted.  Unless otherwise expressly provided herein, no
delay or omission on the part of any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any waiver on
