                            BOK FINANCIAL CORPORATION
                      409A Deferred Compensation Agreement


         This Deferred Compensation Agreement (the "Agreement") is made this
31st day of December, 2004 (the "Agreement Date") between the following parties
(the "Parties"):

i. Mark W. Funke, an individual residing in Edmond, Oklahoma ("Executive"); and,

ii. BOK Financial Corporation, an Oklahoma corporation ("BOKF").

                                    Recitals

         Whereas, Executive and BOKF desire to enter into a Deferred
Compensation Agreement that is compliant with the American Jobs Creation Act of
2004, as codified in Section 409A of the Internal Revenue Code ("Code").

         Now, therefore:

         The Executive and BOKF, in exchange for the promises hereafter set
forth and other good and valuable consideration (the receipt and adequacy of
which the Parties hereby acknowledge), and intending to be legally bound hereby,
agree as follows:

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

a)       Executive is employed by BOKF as its Senior Executive Vice President.

i)       Executive may hereafter be issued performance or restricted shares (as
         provided, from time to time, in the BOKF Executive Compensation Plans)
         and/or awarded options (the "Options") to acquire Common Stock of BOKF
         and has heretofore been awarded options which, as of the Agreement
         Date, have not vested or been exercised, as set forth on Schedule 1
         hereto (such performance shares, restricted shares, and shares of
         Common Stock of BOKF issued upon exercise of the Options, being
         hereinafter collectively called the "Shares").

b)       Executive may hereafter be issued an annual incentive bonus in respect
         of calendar year 2004, payable in March 2005 pursuant to the BOKF
         Executive Compensation Plan (the "2004 Annual Bonus").

c)       This Agreement is entered into in order to permit Executive to defer
         the receipt of all or a portion of the Shares otherwise payable to
         Executive upon the exercise of Options or the vesting of performance
         shares or restricted shares issued to Executive and/or the receipt of
         all or a portion of the 2004 Annual Bonus.

d)       This Agreement sets forth the terms and conditions on which Executive
         may defer the receipt of Shares pursuant to the exercise of the Options
         or the vesting of performance shares or restricted shares, and/or the
         receipt of the 2004 Annual Bonus.

2)       Election to Defer Receipt of Shares. The Executive may, at the sole and
         absolute discretion of the Executive (without any obligation to provide
         an explanation for the exercise of such discretion), elect to defer the
         receipt of Shares upon exercise of Options or the vesting of
         performance or restricted shares, on the following terms and
         conditions:

a)       Executive shall:
i)       not less than six months prior to the vesting of performance shares or
         restricted shares or the intended date of exercise of any of the
         Options, as applicable, give written notice (the "Notice") to BOKF that
         Executive elects to defer the receipt of Shares or the vesting of
         performance or restricted shares (the "Election"); and/or,

ii)      on or before March 15, 2005, give written notice (also called a
         "Notice") to BOKF that Executive elects to defer receipt of some or all
         of the 2004 Annual Bonus (also called an "Election").

b)       Each Notice shall set forth:

i)       the name of the BOKF Stock Option Plan pursuant to which the Options
         were awarded, the date on which the Options were awarded (the "Stock
         Option Award Date"), the number of Shares under option to be exercised;

ii)      the number of Shares which are performance shares or restricted shares
         which Executive elects to defer; and

iii)     the amount of 2004 Annual Bonus which the Executive elects to defer;
         and,

iv)      whether the deferral shall be until retirement or until a date, not
         earlier than five years from the Notice, which executive shall specify
         in the Notice (the "Deferral Date")

c)       Executive agrees to use shares of BOKF Common Stock previously owned by
         him for at least six months to satisfy the exercise price of the
         Options, rather than the cash or broker assisted exercise methods.

d)       In the event Executive elects to defer the vesting of performance
         shares or restricted shares, the Executive shall assign and deliver
         such shares to BOKF together with the Notice of deferral.

e)       The Election shall be irrevocable.

3)       Special BOKF Liability Account.

a)       Upon the exercise of an Option for which an Election has previously
         been made by the Executive pursuant to Section 2 and/or the deferral or
         vesting of Shares which are restricted shares or performance shares
         assigned and delivered to BOKF in accordance with Section 2(d), BOKF
         shall establish a special BOKF Liability Account ("Special Account").

i)       The Special Account shall reflect the number of BOKF Shares for which
         Options were exercised by the Executive, the number of BOKF Shares
         which are performance shares and restricted shares, and the amount of
         2004 Annual Bonus, which Executive has elected to defer. The Executive
         shall pay any FICA taxes that may be due in one or the other of the
         following ways:

(1)      Executive shall pay FICA in cash; or,

(2)      In the case of the deferral of BOKF Shares, the Special Account shall
         be debited that amount of BOKF Shares necessary to pay FICA. Executive
         acknowledges that, in the event Executive elects the provision of this
         sub-paragraph (2), the value of the debited shares shall not be
         deferred under this Agreement and shall be taxable income to the
         Executive, subject to federal and state income tax and withholding.

ii)      BOKF shall periodically (but not less than once each calendar quarter)
         report the number of BOKF Shares reflected in the Special Account and
         related current value of such BOKF Shares to Executive.

iii)     The Special Account shall be for bookkeeping purposes only.

iv)      The Executive shall not, in fact, own the BOKF Shares reflected in the
         Special Account.

b)   If  there  are  any  changes  in  the  capitalization  of  BOKF  (or of any
     Alternative Investment,  as hereafter defined) affecting the number or kind
     (after  the  recapitalization)  of issued  and  outstanding  shares of BOKF
     Common  Stock  (or  the  shares  of any  Alternative  Investment)  existing
     immediately  prior to the change in  capitalization,  whether  such changes
     have been occasioned by reorganization,  combination of shares, declaration
     of stock dividends, stock splits, reverse stock splits, reclassification or
     recapitalization of such stock, the merger or consolidation of BOKF (or any
     Alternative  Investment)  with  some  other  corporation  or other  similar
     transaction,  then the number and kind of shares  reflected  in the Special
     Account shall be  appropriately  adjusted to reflect the number and kind of
     shares the Executive would have owned had the Executive  actually owned the
     BOKF Shares (or shares of Alternative  Investment) reflected in the Special
     Account on the date of such changes.

c)       On the Distribution Date, BOKF shall comply with the provisions
         described in section 5:

4)       Special Diversified Liability Account.

a)       At any time after the exercise of an Option as described in Section 2
         and before the Distribution Date but no more than once each calendar
         quarter, the Executive may elect to convert (the "Conversion") all or a
         portion of the value of the Special Account into a credit value in the
         Special Account equal to the value so converted (less applicable FICA
         taxes). The converted value ("Converted Value") shall be represented by
         one or more Alternative Investments (as hereafter defined) selected by
         Executive.

b)       As a condition of a Conversion, the Executive shall select one or more
         of the investment opportunities listed in Appendix A of this Agreement
         (the "Alternative Investments") to measure the value of the Special
         Account as if such converted Special Account value had actually been
         invested in such Alternative Investments.

c)       After one or more Conversions:

i)       The Special Account shall reflect the BOKF Shares and Alternative
         Investments remaining after each such Conversion and the value thereof
         from time to time.

ii)      BOKF shall periodically (but not less than once each calendar quarter)
         report the BOKF Shares and Alternative Investments reflected in the
         Special Account and related current value thereof to Executive.

iii)     The Special Account shall be for bookkeeping purposes only.

iv)      The Executive shall not own the BOKF Shares or Alternative Investments
         reflected in the Special Account and shall have no right to ownership
         or possession thereof.

v)       BOKF may from time to time amend Exhibit A by adding additional
         investment opportunities to, but not deleting investment opportunities
         from, the list contained in Appendix A.

5)       Distribution Date and Distribution.

a)   The  Distribution  Date for the Special Account shall be a date selected by
     BOKF between  January 15 and March 1 of the year next following the year in
     which the Executive  retires from  BOKF(not less than six months  following
     the date of such  retirement),  his employment  with BOKF is terminated for
     whatever  reason  (not  less  than six  months  following  the date of such
     termination),  or the Deferral Date;  provided,  however,  in the event the
     Executive   becomes   disabled   (as  such  term  is   defined  in  Section
     409A(a)(2)(C)  of the Code) or dies prior to retiring from BOKF or prior to
     his  employment  with BOKF  having  terminated  for  whatever  reason,  the
     Distribution  Date  shall  be a date  selected  by BOKF not  later  than 90
     calendar days following the date of death; and,

b)       If the Executive experiences an unforeseeable emergency (as such term
         is defined in 409A(a)(2)(B) of the Code), Executive may request (i)
         suspension of any deferrals required to be made by Executive and/or
         (ii) receive a partial or full payout from the Special Account. The
         payout shall not exceed the lesser of the Executive's account balance,
         calculated as if such Executive were receiving a termination benefit,
         or the amount reasonably needed to satisfy the unforeseeable emergency.

c)       On the Distribution Date, the Company shall:

i)       Pay the value of the Special Account (net of applicable federal and
         state taxes required to be withheld) to Executive in cash, BOKF Shares,
         Alternative Investments or a combination thereof, in sole the
         discretion of BOKF; and,

ii)      eliminate the Special Account or, in the case of a Distribution
         associated with a Deferral Date, reflect any payment out of the Special
         Account.

d)       In the event of the death of the Executive, the distribution provided
         in the preceding subsection shall be made to the beneficiary or
         beneficiaries previously designated by the Executive in a writing filed
         with the Secretary of BOKF or, in the absence of such designation, as
         provided by Executive in any trust or will and, in the absence of any
         such trust or will, to Executive's estate.

6)       No Executive Interest in Any BOKF Assets.

a)       BOKF shall have no obligation to actually hold BOKF Shares reflected in
         the Special Account or invest funds in any Alternative Investment
         selected by Executive.

b)       If BOKF, in its sole discretion, actually holds BOKF Shares reflected
         in the Special Account or invests BOKF funds in Alternative
         Investments, the Executive shall have no right or interest therein.

c)       The Executive shall have the right under this Agreement only to the
         payment in cash of an amount measured by reference to the values of
         BOKF Shares and Alternative Investments reflected in the Special
         Account (the "Reference Values"). Such contractual right of the
         Executive constitutes the Executive a general unsecured creditor of
         BOKF.

d)       BOKF may satisfy its obligation to pay the Referenced Values by making
         payment in cash or by the delivery of the BOKF Shares and/or
         Alternative Investments by which the Reference Values are determined.

7)       No Enlargement of Employment Rights. Nothing contained in this
         Agreement shall (i) give or be construed as giving the Executive the
         right to be retained in the service of BOKF or (ii) modify or be
         construed as modifying the terms and conditions of employment of
         Executive with BOKF.

8)       Indemnification. Executive hereby agrees to defend and indemnify BOKF,
         and hold BOKF harmless from, all claims of third parties arising out of
         the operations of any Alternative Investment selected by Executive that
         BOKF may actually acquire. BOKF shall not be responsible for any
         decline in value of the Shares or of any Alternative Investment.

9)       Termination of this Agreement. This Agreement shall remain in full
         force and effect from the Agreement Date until Executive's retirement
         or termination; provided, however, either BOKF or Executive may
         terminate the provisions of Section 2 hereof by notice given on or
         before November 1 of any year in which event such termination shall be
         effective as of January 1 immediately following such notice; provided,
         further, no such termination shall effect the time at which any
         distribution shall be made to Executive.

10)      American Jobs Creation Act of 2004 Compliant. The Agreement is intended
         to comply in all regards with Section 409A of the Internal Revenue
         Code, 26 U.S.C. ss. 409A (2004). To the extent that any provision
         contained herein is determined to be non-compliant, such provision
         shall be deemed amended so as to comply with Section 409A and the
         parties hereto shall execute an agreement reflecting such amendment.

11)      Miscellaneous Provisions. The following miscellaneous provisions shall
         apply to this Agreement:

     this  Agreement,  shall be given in writing.  All such  notices and advices
