      or privilege preclude any other or further exercise of the same or of any other
      right, remedy, power, or privilege, nor shall any waiver of any right, remedy,
      power or privilege with respect to any occurrence be construed as a waiver
      of
      such right, remedy, power or privilege with respect to any other occurrence.

      waiver shall be effective unless it is in writing and is signed by the party
      asserted to have granted such waiver.

      This
      Agreement may be executed in any number of counterparts, each of which shall
      be
      deemed to be an original as against any party whose signature appears thereon,
      and all of which shall together constitute one and the same instrument. This

      individually or taken together, shall bear the signatures of all of the parties
      reflected hereon as the signatories.
    (i)    Gender.
      Words
      used herein, regardless of the number and gender specifically used, shall be

      computing the number of days for purposes of this Agreement, all days shall
      be
      counted, including Saturdays, Sundays, and holidays; provided, however, that
      if
