disagreement arising out of or relating to this Agreement (a "Controversy")
shall be submitted to binding arbitration. The arbitration proceeding shall be
conducted by a single arbitrator (the "Arbitrator") in San Antonio, Bexar

the event, the parties cannot agree as to the Arbitrator to be named, each party
to the Controversy shall appoint one arbitrator and those two arbitrators shall
select the Arbitrator.

          8.9.1. Arbitration Procedure. If any party shall desire relief of any
     nature whatsoever from any other party as a result of any Controversy, such
     party will initiate such arbitration proceedings within a reasonable time,
     but in no event more than one (1) year after the facts underlying said
     Controversy first arise or become known to the party seeking relief
     (whichever is later). The failure of such party to institute such
     proceedings within said period shall be deemed a full waiver of any claim
     for such relief. Arbitrator may award the prevailing party its costs for
     the arbitration proceeding, including its reasonable attorneys fees and
     costs. The parties agree that the decision and award of the Arbitrator
     shall be final and conclusive upon the parties, in lieu of all other legal,
     equitable or judicial proceedings between them, and that no appeal or
     judicial review of the award or decision of the Arbitrator shall be taken,
     but that such award or decision may be entered as a judgment and enforced
     in any court having jurisdiction over the party against whom enforcement is
     sought.
