         incurred by the Company, a sum equal to the amount of the Offset,
         obligation or liability so incurred by the Company (all obligations of
         the Obligor under this Section 1.1(a) being referred to herein as the

         Related Documents or under any other agreement between the Obligor and
         the Company or that may now or hereafter exist in law or in equity or
         by suit or otherwise. No delay or failure to take action on the part of
         the Company in exercising any right, power or privilege shall operate
         as a waiver thereof, nor shall any single or partial exercise of any
         such right, power or privilege preclude other or further exercise
         thereof or the exercise of any other right, power or privilege or shall
         be construed to be a waiver of any Event of Default. No course of
         dealing between the Obligor and the Company or their agents or
         employees shall be effective to change, modify or discharge any
         provision of this Agreement or any of the Related Documents or to
         constitute a waiver of any Event of Default.
