                  hereafter  be  amended  in  accordance   with  the  provisions
                  hereof."

                  2.       Amendment to Section 3.12.

Agreement,  as such  Schedules may  hereafter be amended in accordance  with the
provisions hereof)."

                           2.2      The following clause (h) is added at the end
of Section 3.12:

                  "(h)  Notwithstanding   anything  to  the  contrary  contained

                  published by the authorities  described at the end of Schedule

                  replace the POPs reflected  thereon with the POPs for the year
                  2000 as so published, and from and after such amendment,  each
                  reference to POPs included in this  Agreement,  shall refer to
                  the POPs which appear on Schedules 3.12(a) and 3.12(b),  as so
                  amended."
