acceptable to the other Party.  Seller and Purchaser  agree that final  judgment
(with all right of appeal having expired or been waived)  against it in any such
action,  suit or  proceeding  shall be  conclusive  and that the other  Party is
entitled  to enforce  such  judgment  in any other  jurisdiction  by suit on the
judgment, a certified copy of which shall be conclusive evidence of the fact and
amount of indebtedness arising from such judgment.

Section 4.13      Binding Effect

hereto  and  their  respective  heirs,  successors,  legal  representatives  and
assigns.

limitation,  fire,  flood,  strike or other industrial  disturbance,  failure of
transport,   accident,  war,  riot,  insurrection,   act  of  God  or  order  of
