          8. TERM AND TERMINATION OF AGREEMENT. This Agreement shall commence on

"Good Reason" or

                                                                               5

Notice, the parties shall appoint an independent arbitrator experienced in
employment matters who shall determine which section of this Section 8 applies
to the termination. In the event the parties cannot agree on an arbitrator

otherwise. Any arbitration hereunder shall be conducted in Cleveland, Ohio in

rights of the Disputing Party to challenge the claimed basis for termination

Summa's physician(s), that Dr. Summa is disabled and unable to perform the
essential function of his position with or without reasonable accommodations, it

Summa shall be entitled to his salary through the date of such termination,

Under any such termination for Cause, all rights, benefits, obligation and
duties of the parties hereunder shall immediately cease, except any compensation
due and owing through the date of termination and/or fringe benefits which have
vested on Dr. Summa's behalf prior to such termination, if any.

governs such termination (i.e., if the party terminating Dr. Summa's employment
(the "Terminating Party") claims that "Cause", "Good Reason", "Disability" or
"Change of Control" exists and the other party (the "Disputing Party") disputes
