                           Amended as of June 14, 2002

           This Employment Agreement ("Agreement") is made, effective as of
April 14, 1997 (the "Effective Date") among First National Bank of Park Cities
(the "Bank"), BOK Financial Corporation ("BOKF") and C. Fred Ball, Jr., an
individual residing in Dallas, Texas (the "Executive").

           The Bank and Executive, in consideration of the promises and
covenants set forth herein (the receipt and adequacy of which is hereby
acknowledged) and intending to be legally bound hereby, agree as follows:

(1)  Purpose of This Agreement. The purpose of this agreement is as follows:

          (a)  The Bank is a national  association  formed under and pursuant to
               the laws of the United States of America.  The Bank is engaged in
               the banking business in Dallas, Texas.

               Cities  Corporation is owned by Park Cities  Bancshares,  Inc., a
               Texas corporation ("PC Bancshares").  BOKF owns all of the issued
               and  outstanding  capital  stock  of PC  Bancshares.  Thus,  BOKF
               indirectly owns the Bank and TFB.

               years.

               enter the employment of the Bank.

          (e)  The  purpose  of this  Agreement  is to set  forth  the terms and
               conditions on which the Bank shall employ the Executive  from and
               after the Effective Date.

               necessary  to the  affairs  of the Bank and shall  serve the Bank
               diligently, loyally, and to the best of his ability.

          (d)  Executive shall serve in such other or additional positions as an

               Texas.

          (e)  In the  event,  the Bank and FTB are  merged,  as is the  present

                    date of the action of the  majority of the Board of the Bank
                    finding the  termination  was with  cause.  In the event the
                    Bank terminates this Agreement for cause, (A) the Bank shall
                    pay Executive the  Executive's  then Annual Salary  through,
