less the federal benefit, medicare, and assuming the FICA limit has already been
met, the composite  rate would be 41% broken down as follows:  35% Federal 4.55%
State (after federal deduction) 1.45% Medicare or a total 41%.

     does  not  return  to  work  on  a  full-time  basis,  BOKF  may  terminate

          of the Term),  Executive shall not directly or indirectly  (whether as
          an officer,  director,  employee,  partner,  stockholder,  creditor or
          agent, or  representative  of other persons or entities) engage in the
          banking business or in any business in which the BOKF or any affiliate
          of the BOKF  has,  as of the  date of such  termination  engaged  (the
          "banking business" or "banking  services"),  in Dallas County,  Texas,
          Harris County Texas,  Tarrant  County,  Texas,  or any county in which
          BoT,  BoA, or CSBT  maintains  a banking  office,  or in any  counties
          contiguous to any of such counties (the "Trade  Area"),  provided that
          the  foregoing  shall not apply to ownership by Executive of up to ten
          percent  (10%) of the  common  stock of a  corporation  traded  on the
          facilities of a national  securities  exchange  engaged in the banking
          business  of which  Executive  is not a director,  officer,  employee,
          agent or representative.

     (b)  Executive agrees (the "Non-Solicitation  Agreement") that,for a period
          of two (2) years  following  any  termination  of the  Employment  for
          cause,  and for a period of one (1) year following any  termination of
          the Employment for any reason other than cause  (including  expiration
          of the Term),  Executive shall not directly or indirectly  (whether as
          an officer,  director,  employee,  partner,  stockholder,  creditor or
          agent,  or  representative  of other  persons or entities)  contact or
          solicit, in any manner indirectly or directly, individuals or entities
          who were at anytime  during the original or any extended  Term clients
          of BOKF or any of its affiliates for the purpose of providing banking,
          trust,  investment,  or other banking services provided by BOKF or any
          of its affiliates  during the Term or contact or solicit  employees of
          BOKF or any affiliates of BOKF to seek  employment  with any person or
          entity except BOKF and its affiliates. This Non-Solicitation Agreement
          shall not apply to ownership  by Executive of up to ten percent  (10%)
          of the common stock of a  corporation  traded on the  facilities  of a
          national  securities exchange engaged in the banking business of which
          Executive   is  not  a   director,   officer,   employee,   agent   or
          representative.

     (c)  BOKF shall  promptly  following  the  executive of this  Agreement pay
          Executive $10,000 as additional  consideration for the Non-Competition
          Agreement  which  Executive  agrees  is,  with the  payment  hereafter
          described,  full and fair consideration for such agreement. BOKF shall
          pay  Executive,  in  addition  to any other  amounts  which may be due
          Executive,  during each year in which the Non-Competition Agreement is

          customary payroll  deductions for FICA, federal and state withholding,
          and the like,  at the times and in the manner in effect in  accordance
          with the usual and customary payroll policies generally in effect from
          time to time at BOKF.

     (d)  Executive   agrees  that  the   Non-Competition   Agreement   and  the
          Non-Solicitation  Agreement and all the restrictions set forth therein
          are fair and reasonable.

 10


     (e)  Executive  agrees  that (i) any  remedy  at law for any  breach of the
          Non-Competition  Agreement and/or Non-Solicitation  Agreement would be
          inadequate,  (ii) in the event of any  breach  of the  Non-Competition
          Agreement  and/or  Non-Solicitation   Agreement,  the  Non-Competition
          Agreement and  Non-Solicitation  Agreement,  as the case may be, shall
          constitute  incontrovertible  evidence of irreparable  injury to BOKF,
          and (iii) BOKF  shall be  entitled  to both  immediate  and  permanent
          injunctive relief without the necessity of establishing or posting any
          bond therefor to preclude any such breach (in addition to any remedies
          of law which BOKF may be entitled).

(8)  Confidential Information.

     (a)  Executive  acknowledges  that,  during the Term and prior to the Term,
          Executive  has had and will have access to  Confidential  Information,
          all of which  shall be made  accessible  to  Executive  only in strict
          confidence;  that unauthorized disclosure of Confidential  Information
          will damage the BOKF's business;  that Confidential  Information would
          be susceptible to immediate competitive application by a competitor of
          the BOKF; that BOKF's business is substantially dependent on access to
          and  the  continuing   secrecy  of  Confidential   Information;   that
          Confidential  Information  is  unique  to the BOKF and  known  only to
          Executive and certain key employees and  contractors of BOKF; that the
          BOKF  shall  at  all  times  retain   ownership  and  control  of  all
          Confidential Information;  and that the restrictions contained in this
          paragraph  are  reasonable  and  necessary  for the  protection of the
          BOKF's business.

     (b)  All documents or other records  containing or reflecting  Confidential
          Information  ("Confidential Documents") prepared by or
          to which Executive has access are and shall remain the property of the
          BOKF.  Executive shall not copy or use any  Confidential  Document for
          any purpose not relating  directly to  Executive's  work on the BOKF's

          party other than the BOKF and its employees.  Upon the  termination of

          termination,  Executive shall  immediately  deliver to the BOKF or its
          designee (and shall not keep in  Executive's  possession or deliver to
          anyone  else)  all  Confidential  Documents  and  all  other  property
          belonging to the BOKF.  This  paragraph  shall not bar  Employee  from
          complying  with any subpoena or court order,  provided that  Executive
          shall at the earliest  practicable date provide a copy of the subpoena
          or court order to the BOKF's Chief Executive Officer.

     (c)  During  the  Term  and for a  period  of four  (4)  years  thereafter,
          regardless of the reason for  termination of  Executive's  employment,
          (i) Executive shall not disclose any  Confidential  Information to any
          third party and (ii)

 11

          Executive shall use  Confidential  Information only in connection with
          and  in  furtherance  of  Executive's   work  for  the  BOKF  and  its
          affiliates.

          business;  the BOKF's business plans and strategies;  electronic files
          or documents  prepared by BOKF or Executive  containing the identities
          of the BOKF's  customers  (including  their  addresses  and  telephone

          the specific  individual  customer needs being  addressed by the BOKF;
          the nature of fees and charges assessed by the BOKF;  nonpublic forms,
          contracts and other documents used in the BOKF's business;  the nature
          and content of any  proprietary  computer  software used in the BOKF's
          business,  whether owned by the BOKF or used by the BOKF under license
          from a third party; and all other nonpublic information concerning the
          BOKF's  concepts,  prospects,   customers,   employees,   contractors,
          earnings, products, services,  equipment,  systems, and/or prospective
          and executed contracts and other business  arrangements.  Confidential
