its Exhibits, together with the provisions of the Note and other documents
specifically identified herein, constitute the final, complete and exclusive
agreement between the parties hereto relating to the subject matter hereof
superseding all prior or contemporaneous oral or written understandings with
respect to such subject matter, and no amendment or waiver of any provision of

determining any claim. Any controversy concerning whether an issue is arbitrable
shall be determined by the arbitrator(s). Judgment upon the arbitration award
may be entered in any court having jurisdiction. The institution and maintenance
of an action for judicial relief or pursuit of a provisional or ancillary remedy

contests such action for judicial relief. No provision of this Section shall
limit the right of any party to obtain provisional or ancillary remedies from a
court of competent jurisdiction before, after or during the pendency of any
