thirty (30) days, advising of its arbitrator. The umpire shall thereafter be chosen by the two
(2) arbitrators. In the event either party fails to designate its arbitrator as indicated
above, the other party is hereby authorized and empowered to name the second arbitrator, and the
party which failed to designate its arbitrator shall be deemed to have waived its rights to
designate an arbitrator and shall not be aggrieved thereby. The two (2) arbitrators shall then

provided, the expenses of the arbitrators, the umpire and the arbitration shall be equally
divided between the two parties. The arbitrators may allocate any and all of the costs and fees
against the losing party upon a determination that the position of the losing party was, in
whole or in part, groundless, specious or otherwise without merit or asserted primarily for the
purposes of obfuscation or delay.14.
    Additional terms and conditions applicable to this Agreement are set forth in Schedule
C. The provisions in Schedule A, Schedule B and Schedule C
