or unenforceable the remaining terms and provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of
this Agreement in any other jurisdiction. If any provision of this Agreement is
so broad as to be unenforceable, such provision shall be interpreted to be only
so broad as is enforceable.

16. Further Assurances. Each party hereto shall execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

17. Third Party Beneficiaries. Nothing in this Agreement, expressed or implied,
shall be construed to give any person other than the parties hereto any legal or
