ITEM 9. UNDERTAKINGS

(a) The undersigned Registrant hereby undertakes:


(1) To file during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to;

(i) include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) reflect in the prospectus any facts or events arising after the effective date of the registration statement (or most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the Calculation of Registration Fee table in the effective registration statement; and

(iii)include any additionalh or changed material information with respect to the plan of distribution not previously disclosed in the registration statement or any material statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) or the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

(2) That, for the purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering for such securities at the time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of it counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.


SIGNATURES

Pursuant to the requirement of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement, or amendment thereto, to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Tulsa, State of Oklahoma on the 24th day of June, 2003.

BOK FINANCIAL CORPORATION

INDEPENDENT COMPENSATION COMMITTEE

2003 EXECUTIVE INCENTIVE PLAN
(FOR DIRECT REPORTS TO THE CHIEF EXECUTIVE OFFICER)

March 25, 2003

Independent Compensation Committee. In December 2002, the Board of Directors of BOKF established an Independent Compensation Committee, consisting of five outside directors, to administer a performance-based compensation plan for senior executives in accordance with the provisions of Section 162m of the Internal Revenue Code. The current members of the Committee are Messrs. Cappy, Kyle, Rooney, Robinson, and Corbett. The Independent Compensation Committee has developed a performance-based compensation plan for 2003 which is called the 2003 Executive Incentive Plan and is hereafter described.

Incentive Compensation Generally. The Company employs a wide range of incentive compensation for its employees. Except for performance-based compensation which is intended to comply with the requirements of Section 162m, such incentive compensation is administered by the Chief Executive Officer and senior management. The Independent Compensation Committee administers the Performance-Based Compensation Plan.

2003 BOKF Executive Incentive Plan. The 2003 BOKF Executive Incentive Plan consists of (i) annual incentive bonus and (ii) long term incentive compensation. Executives who report directly to the Chief Executive Officer and other officers designated by the Chief Executive Officer may participate in the Plan.

2003 Annual Incentive Bonus. The 2003 Annual Incentive Bonus will be determined as follows:

o The target Annual Incentive Bonus will equal 40% of Base Annual Salary.

o A participant will earn the Annual Incentive Bonus based on a matrix pursuant to which 33% of the target will be earned if 80% of the goal is met, 100% of the target will be earned if 100% of the goal is met and 200% of the target will be earned if 120% of the goal is met.


o The 2003 Annual Incentive Grid is as follows:

Actual vs. Goal         Incentive Payout

80%                     33%
85%                     50%
90%                     67%
95%                     83%
100%                    100%
105%                    125%
110%                    150%
115%                    175%
120%                    200%

2003 Long Term Incentive. The 2003 Long Term Incentive will be determined as follows:

o The target Long Term Incentive will be established by the Chairman of the Board and the Chief Executive Officer for each Plan participant, with approval of the Committee for that compensation intended to comply with
Section 162m.

o A participant will earn long term incentive based on a matrix pursuant to which 25% of the targeted long term incentive compensation will be earned if the goal less five percentage points is met, 100% of the targeted long term incentive compensation will be earned if 100% of the goal is met, and 150% of the targeted long term compensation will be earned if the goal plus five percentage points is met.

2003 Performance-Based Compensation Measures. The measure against which each participant's performance will be based is the weighted average of (i) Company earnings per share measured against peer group earnings per share and (ii) business unit actual controllable value added measured against business unit planned controllable value added and attainment of individually established goals.

o By achieving 120% of the Annual Incentive Bonus measure, each participant will earn 200% the Annual Incentive Bonus. The 2003 Annual Incentive Bonus measure is the earnings per share growth of the 50th percentile (or median) of a peer group of banks for the trailing two-year period determined as of the end of the year in respect of which the bonus is being paid.

o By achieving the Long Term Incentive measure plus five percentage points, each participant will earn 150% of the Long Term Incentive. The 2003 Long Term Incentive Measure is the earnings per share growth of the 50th percentile (or median) of a peer group of banks for the trailing three-year period determined as of the second anniversary of the end of the year in respect of which the compensation is being paid and the planned business unit performance and any individually established goals.

o The Chief Executive Officer will assign the Company earnings and business unit weightings to participants on an individual basis. With respect to compensation intended to qualify under Section 162m, the Committee will approve the weightings and any individually established goals prior to March 31.

o Fifty percent of the Annual Incentive Bonus and fifty percent of the performance shares issued for Long Term Incentive Compensation, calculated on the foregoing basis, will be subject to downward adjustment at the discretion of the Independent Compensation Committee based upon recommendations of the Chief Executive Officer.

Payment of Long Term Incentive Compensation. Long Term Incentive Compensation will be paid by the award of options pursuant to the BOKF 2003 Stock Option Plan, by the issuance of performance shares, or by a combination of options and performance shares.

o Performance shares will be shares of BOKF Common Stock issued before March 15 of the year in respect of which the long term incentive compensation is being paid. Performance shares will vest only on the fifth anniversary of the last day of the year for which the shares are issued. If the employment of the Executive is terminated


for any reason prior to such vesting the shares will be forfeited. The shares may not be sold for three years after the shares vest unless, following such sale, the Executive would own that number of shares of BOKF Common Stock provided for in any Executive Management BOKF Common Stock Ownership Guidelines which may be established from time to time by the Independent Compensation Committee. Additional performance shares will be issued, or performance shares will be forfeited, in accordance with the performance goals discussed above. No more than 30,000 performance shares may be issued in any year to a participant.

o Stock options will be options issued pursuant to the BOKF 2003 Stock Option Plan. The Options may not be exercised prior to the expiration of the three year performance period.

o The Chief Executive will, prior to April 1, 2003 specify for each participant the percentage of the 2003 Long Term Incentive that will be paid by the award of options and the percentage that will be paid by the issuance of shares of BOKF Common Stock.

Peer Group of Banks. The Independent Compensation Committee will select the peer group of bank holding companies in accordance with the following guidelines.

o The peer group will include only publicly-traded United States bank holding companies (BHC's) as defined in SNL Securities Public Trading BHC Database.

o An equal number of BHC's above and below BOKF's asset size will be chosen. The BHC's should be no more than double BOKF's size and no less than half BOKF's asset size, provided the number of BHC's chosen for the peer group totals at least 26.

o Asset size means total assets at the end of the calendar year for which the compensation is being paid.

o The source for peer information will be SNL Securities Public Traded BHC Database that obtains information from public information, primarily through periodic SEC filings and company press releases. SNL Securities is a widely accepted database used in the industry for analytical purposes.

o The earnings per share (EPS) amounts extracted from the SNL database will be diluted EPS as defined by generally accepted accounting principles.

o Growth in peer group EPS will be calculated annually from source EPS data from the SNL database.

Determination of Performance-Based Compensation. The calculation of performance based compensation by the Independent Compensation Committee will be binding upon all participants provided only that the Independent Compensation Committee acts in good faith.


Time and Payment of Performance-Based Compensation. All performance-based compensation intended to comply with Section 162m must be certified by the Committee prior to payment. The Annual Incentive Bonus will be calculated and paid prior to March 15 of the year following the year for which the bonus is being paid. The Long Term Incentive will be calculated and additional options and shares issued or forfeited prior to March 15 following the second anniversary of the end of the calendar year for which the compensation is being paid.

Selected Officers. Selected officers will be paid discretionary performance-based compensation based upon achievement of individual objectives as determined by the Chief Executive Officer.
