Notwithstanding the foregoing paragraph, if during the term of this
Agreement any playing or scoring rule is proposed to be changed, the
Clubs agree that they shall give the Association notice thereof, and
shall negotiate the proposed change with the Association, provided that
the obligation to negotiate with the Association shall apply only to
changes which significantly affect terms and conditions of employment.
Such proposals to change playing or scoring rules shall normally
be made only during the off-season. If the Clubs and the Association
fail to reach agreement on a proposed change which is subject to negotiation,
the proposed change shall not be put into effect until the completion
of the next complete succeeding season (including the Division
Series, League Championship Series and World Series) following the
date the change was proposed.
