matters in question between them, arising out of or related to this Agreement,
and the rights, duties and obligations arising thereunder or the breach thereof,
shall be decided by common-law arbitration in Pittsburgh, Pennsylvania, in
accordance with the Rules of the American Arbitration Association then
