                                   ARTICLE 13

                               SUBSTITUTION CLAUSE

Should any individual provision of this Agreement be or become void, or should a
gap be ascertained in this Agreement, the validly of the other provisions shall
not be affected thereby. As a substitute for the provision, which is void or
inoperative, or for the purpose of filling the gap, an appropriate arrangement
shall be valid, which, if it is legally possible, shall be as close as possible
to what the contracting parties would have intended, had they reasonably
considered that point. If a

                                       10



provision is void or inoperative owing to measures or outputs or times (periods
or time limits) indicated therein, this shall be replaced by a measure which is
as close as legally possible to the provision in question.
