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 31st day of May, 2001.

This document constitutes part of a Section 10(a) Prospectus covering the securities that have been registered under the Securities Act of 1933. The documents constituting the
Section 10(a) Prospectus are held in a file maintained by the Benefits Department of Human Resources and may be reviewed or obtained, without charge, upon written or oral request made to the Compensation Department of Human Resources of Bank of Oklahoma, National Association, P.O. Box 2300, Tulsa, Oklahoma 74172, telephone number (918) 588-6277.


BOKF 2001 STOCK OPTION PLAN

(a) ESTABLISHMENT, PURPOSE AND EFFECTIVE DATE OF PLAN.

(1) Establishment. BOK Financial Corporation (the "Corporation" or "BOKF"), an Oklahoma corporation, hereby establishes the "BOKF 2001 Stock Option Plan" (the "BOKF 2001 Plan") for designated employees of the Corporation and of various direct and indirect subsidiaries of the Corporation (collectively, "BOKF").

(2) Purpose. The purpose of the BOKF 2001 Plan is to advance the interests of the Corporation (i) by encouraging and providing for the acquisition of an equity interest in the Corporation by key employees of BOKF and (ii) by enabling BOKF to attract and retain the services of key employees whose judgment, interest, and special effort are desired for the successful conduct of operations

(3) Effective Date. The BOKF 2001 Plan shall become effective on May 1, 2001 (or on such later date as a registration statement in respect of the BOKF 2001 Plan on Securities and Exchange Commission Form S-8 shall become effective).

(b) THE 2001 OPTIONS. The options ("2001 Options") established hereby are the right to purchase shares of Common Stock of the Corporation on the terms and conditions hereafter set forth in this and succeeding sections of the BOKF 2001 Plan:


(1) The Common Stock subject to the 2001 Options shall be the Common Stock of the Corporation, par value $0.00006 per share ("BOKF Common Stock").

(2) The Corporation may issue Award Letters (as hereafter defined) at any time prior to January 1, 2010

(3) The owners of the 2001 Options shall be those employees (hereafter called a "Participant") to whom a letter of award ("Award Letter") is hereafter delivered by the Chairman of the Board and the Chief Executive Officer of the Corporation pursuant to the BOKF 2001 Plan.

(4) The 2001 Options owned by each Participant shall entitle the Participant, subject to the terms and conditions hereof, to purchase that number of shares of BOKF Common Stock set forth in one or more Award Letters delivered to the Participant from time to time ("Participant's 2001 Option Shares").

(5) Each Award Letter shall bear the date on which the Award Letter is issued (the "Award Date").

(6) The total number of shares of BOKF Common Stock subject to 2001 Options shall be 1,500,000.

(7) If the employment of a Participant is terminated for any reason and such Participant has not exercised the 2001 Options with respect to any shares, the Corporation may award 2001 Options in respect of such shares to existing Participants or to additional Participants by issuing additional Award Letters prior to January 1, 2010.


(8) The purchase price of shares subject to the 2001 Options shall be the average of the mid-points between the highest price and the lowest price at which trades occurred (or, in the event of a single trade, the price of such trade) for BOKF Common Stock on NASDAQ on the five (5) trading days on which at least one trade actually occurs immediately preceding the date of the Award Letter (the "Option Price").

(9) The 2001 Options may be exercised during and only during the period of time commencing on the second anniversary of the Award Date and ending at 5:00 P.M. Tulsa Time on the forty-fifth (45th) calendar day thereafter.

(ii) in cash or its equivalent, or (iii) by tendering shares of BOKF Common Stock having a value equal to the purchase price based on the closing price quoted for BOKF Common Stock on NASDAQ on the trading day immediately preceding the date of exercise (provided such shares of BOKF Common Stock must have been held by the Participant for a period in excess of six months), or (iv) a combination of (i), (ii), or (iii).


(11) The Corporation shall deliver to the Participant the certificates representing the shares purchased pursuant to the exercise of the 2001 Options within thirty (30) days of the date of exercise.

(1) Non-Transferability. The 2001 Options may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, otherwise than by will or by the laws of descent and distribution.

(2) Termination of 2001 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 2001 Options shall automatically terminate, to the extent not previously exercised, provided:


(a) The Chairman of the Board and the Chief Executive Officer may in their sole discretion (which discretion may be exercised without any obligation to provide any explanation for the exercise of such discretion), subject to approval of the Board of Directors of the Corporation, extend the termination of the Participant's 2001 Options in special circumstances.

(b) In 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 2001 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 2001 Option Shares.

(c) In 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 2001 Option Shares (whether vested or un-vested, to the extent not previously purchased).


(d) A Change of Control shall be deemed to have occurred if, and only if:

(a) 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. Kaiser, affiliates of George B. Kaiser, or members of the family of George B.

Kaiser); or,

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

(e) A 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.


(f) A 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) 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 2001 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.


(4) Waiver of Shareholder Rights. The Participant or other person entitled to exercise 2001 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 2001Options 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.

(d) REOFFER OR RESALE OF BOKF STOCK ACQUIRED PURSUANT TO EXERCISE OF THE 2001 OPTIONS. The reoffer or resale of BOKF Common Stock acquired by a Participant pursuant to the 2001 Options shall be subject to the following terms and conditions:

(1) Reoffer or Resale by Affiliate. If the Participant is an affiliate of the Corporation, the reoffer or resale of BOKF Common Stock may be made by the Participant only (i) by means of a reoffer prospectus pursuant to an effective registration statement on Form S-8 or (ii) in accordance with the provisions of SEC Rule 144 or (iii) pursuant to the determination of the Corporation's general counsel that there is an available exemption under the federal and state securities laws.

(3) Prior Approval of Counsel. Prior to reoffering or reselling any BOKF Common Stock acquired pursuant to a 2001 Option, the Participant shall advise the Compensation Department of Human Resources of Bank of Oklahoma, National Association which shall refer the matter to the Corporation's general counsel. The Corporation's general counsel shall determine whether the Participant is an affiliate or a non-affiliate of BOKF. If the Corporation's general counsel determines Participant is an affiliate, the Participant shall offer and sell the BOKF Common Stock only as provided by Section 4.1.

(4) Reoffer Prospectus. BOKF shall use its reasonable best efforts to provide any Participant who is an affiliate and desires to sell BOKF Common Stock with a reoffer prospectus at reasonable times.


(e) NOT AN EMPLOYMENT AGREEMENT. This BOKF 2001 Plan is not an employment agreement.
