- 5 -

--------------------------------------------------------------------------------

provision. No waiver of any breach of or non-compliance with this Agreement

determined to be unenforceable by reason of its extension for too great a period

activities, it shall be interpreted to extend only over the maximum period of
time, geographic area or range of activities as to which it may be enforceable.
