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 additional 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.

3.2 Termination of 2003 Options Upon Termination of Employment of Participant. If the employment of the Participant by BOKF shall terminate for any reason including death, disability, retirement, resignation or involuntary termination (whether such involuntary termination is with or without cause), the Participant's 2003 Options shall automatically terminate, to the extent not previously exercised, provided:

3.2.1The Chairman of the Board and the Chief Executive Officer may, in their sole discretion (which discretion may be exercised arbitrarily) subject to approval of the Board of Directors of the Corporation, extend the termination of the Participant's 2003 Options in special circumstances.


3.2.2In the event of the termination of employment of a participant by reason of death or disability, the Participant (or, in the event of death, the personal representative of the Participant) may purchase, any of Participant's 2003 Option Shares which the Participant had the right to purchase immediately preceding the date of the Participant's termination of employment within the period of time such Participant could have, but for such termination, purchased such 2003 Option Shares.

3.2.3In the event a Participant's employment is involuntarily terminated by BOKF without cause (determined in accordance with
Section 3.2.5) and such involuntary termination without cause is within one year of a Change of Control (as defined in Section 3.2.4), the Participant may purchase, within 90 days of the date of the Participant's termination of employment, all of Participant's 2003 Option Shares (to the extent not previously purchased).

3.2.4A Change of Control shall be deemed to have occurred if, and only if:

3.2.4.1 George B. Kaiser, affiliates of George B. Kaiser, and/or members of the family of George B. Kaiser collectively cease to own more shares of the voting capital stock of BOKF than any other shareholder (or group of shareholders acting in concert to control BOKF to the exclusion of George B.

3.2.4.2 BOKF shall cease to own more than 50% of the voting capital stock of Bank of Oklahoma, National Association.

3.2.5A Participant shall be deemed to have been terminated for cause if the Board of Directors of BOKF determines (in its sole discretion provided only that such discretion is exercised with honesty in fact) that the Participant was terminated by reason of
(i) any failure to substantially perform Participant's employment obligations to BOKF in a satisfactory manner, (ii) any intentional act materially injurious to BOKF, (iii) any act of moral turpitude, (iv) any material dishonest or fraudulent act, or (v) any refusal to obey orders or instructions of the Participant's appropriate supervisors or seniors.

3.2.6A Participant shall be deemed employed by BOKF so long as and only so long as the employee is in the employment of BOK Financial Corporation or a direct or indirect subsidiary of BOK Financial Corporation in which BOK Financial Corporation owns, directly or indirectly, more shares of the voting capital stock than any other shareholder (or group of shareholders acting in concert to control such subsidiary to the exclusion of BOKF).

3.3 Adjustments. If there are any changes in the capitalization of the Corporation affecting the number or kind (after the recapitalization) of issued and outstanding shares of BOKF Common Stock (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 the Corporation with some other corporation or other similar transaction, then the number and kind of shares then subject to the 2003 Options and the price to be paid therefor, shall be appropriately adjusted by the Corporation; provided, however, that in no event shall any such adjustment result in the Corporation being required to sell or issue a fractional share of stock.

3.4 Waiver of Shareholder Rights. The Participant or other person entitled to exercise 2003 Options shall have no rights as a stockholder with respect to any shares subject thereto until the Participant or such person shall have exercised the 2003 Options and shall thereafter have become the holder of record of such shares and no adjustment (except such adjustments as may be effected pursuant to the provisions of
Section 3.3 hereof) shall be made for dividends or distributions of rights in respect of such shares for which the record date is prior to the date on which the Participant or such person so becomes the holder of record.
