    (vi) The
Parties have participated jointly in the negotiation and drafting of this
Agreement.  If an ambiguity or question of intent or interpretation
arises, this Agreement shall be construed as if drafted jointly by the Parties
and no presumption or burden of proof shall arise favoring or disfavoring any
Party by virtue of the authorship of any of the provisions hereof.
