PROXY STATEMENT FOR ANNUAL MEETING OF SHAREHOLDERS

To be held April 25, 2006

General

The enclosed proxy is solicited on behalf of the Board of Directors of BOK Financial Corporation for use at our annual meeting of shareholders. The annual meeting will be held on Tuesday, April 25, 2006, at 11:00 a.m. local time in the Tulsa Room on the ninth floor of the Bank of Oklahoma Tower, One Williams Center, Tulsa, Oklahoma.

These proxy materials will be mailed on or about March 23, 2006 to holders of record of common stock as of the close of business on March 1, 2006.

Voting by proxy

You may vote at the annual meeting by completing, signing and returning the enclosed proxy card. If not revoked, your proxy will be voted at the annual meeting in accordance with your instructions marked on the proxy card. If you fail to mark your proxy with instructions, your proxy will be voted as follows:

•

FOR the election of the eighteen (18) nominees for director listed in this Proxy Statement; and,

•

FOR the amendment of the 2003 BOKF Stock Option Plan

As to any other matter that may be properly brought before the annual meeting, your proxy will be voted as the Board of Directors may recommend. If the Board of Directors makes no recommendation, your proxy will be voted as the proxy holder named in your proxy card deems advisable. The Board of Directors does not know of any other matter that is expected to be presented for consideration at the annual meeting.

Any shareholder executing a proxy retains the right to revoke it any time prior to exercise at the annual meeting. A proxy may be revoked by delivery of written notice of revocation to the Secretary of BOK Financial, by execution and delivery of a later proxy or by voting the shares in person at the annual meeting. If not revoked, all shares represented by properly executed proxies will be voted as specified therein.

Voting and quorum requirements at the meeting

Only holders of shares of common stock at the close of business on March 1, 2006, (the “record date”) are entitled to notice of and to vote at the annual meeting. On the record date, there were 66,955,508 shares of common stock entitled to vote.

You will have one vote for each share of common stock held by you on the record date.

In order to have a meeting it is necessary that a quorum be present. The presence in person or by proxy of the holders of one-third of the outstanding shares of common stock is necessary to constitute a quorum at the annual meeting. Abstentions and broker non-votes will be counted for purposes of determining the presence or absence of a quorum. Abstentions and broker non-votes will not be counted as having voted either for or against a proposal.

The affirmative vote of the holders of a majority of the shares present or represented at the meeting in which a quorum is present that actually vote for or against the matter is required. Directors are elected by a plurality vote, meaning that the eighteen (18) nominees receiving the highest number of votes FOR will be elected as directors. The affirmative vote of the holders of a majority of the shares of common stock, present in person or by proxy, voted at the meeting, is required for approval of the foregoing amendments to the 2003 Plan.

George B. Kaiser currently owns approximately 66.7% of the outstanding common stock and plans to vote in person at the meeting.

Solicitation of proxies

We are paying for all our costs incurred in soliciting proxies for the annual meeting. In addition to solicitation by mail, we may use our directors, officers and regular employees to solicit proxies by telephone or otherwise. These personnel will not be specifically compensated for these services. We will pay persons holding shares of common stock for the benefit of others, such as nominees, brokerage houses, banks, and other fiduciaries, for the expense of forwarding solicitation materials to the beneficial owner.

Annual report

Our Annual Report to Shareholders, covering the fiscal year ended December 31, 2005, including audited financial statements, is enclosed. No parts of the Annual Report are incorporated in this Proxy Statement or are deemed to be a part of the material for the solicitation of proxies.

The BOKF Directors Stock Compensation Plan further provides that the issuance price for the director compensation shares is the average of the mid-points between the highest price and the lowest price at which trades occurred on NASDAQ on the five trading days immediately preceding the end of the calendar quarter. All non-officer directors also are paid $500 in cash for each board of directors or committee meeting attended (provided only one fee is paid when two or more committees meet contemporaneously) and $1,000 in cash for each committee meeting chaired.

In addition, the Chairman of the Risk and Audit Committee receives $250 for each quarterly earnings release conference and upon application to, and subject to the discretion of, the Committee, $250 for each additional substantive conference with the Company’s independent auditors or management in fulfillment the duties and responsibilities of the Committee.

All directors of BOK Financial attended 75% of all meetings of the Board of Directors and committees on which they served, except Ms. Marshall-Chapman and Mr. Robinson, who were unable to attend 75% of the meetings due to business and personal conflicts. Although BOK Financial does not have a policy with respect to attendance by the Directors at the Annual Meeting of Stockholders, Directors are encouraged to attend. Eighteen of the 22 members of the Board of Directors attended the 2005 Annual Meeting of Stockholders. The Board of Directors intends to meet at least four times in 2006.

Director Nominations

While the Board of Directors does not have a standing nomination committee, director candidates identified by management and members of the Board of Directors are discussed at virtually every Board of Directors meeting.

integrity; (ii) Strong sense of professionalism; and, (iii) Capability of serving the interests of stockholders, and several of the following characteristics: (i) Prominence in the community; (ii) Significant relations with one of the Company’s subsidiary banks; (iii) Ability to represent the views of under-represented constituencies in the Company’s market areas; (iv) Financial analytical skill and expertise; and, (v) Vision for social trends.

The Board of Directors will consider director candidates recommended by stockholders if provided with the following: (i) evidence in accordance with Rule 14a-8 of compliance with stockholder eligibility requirements; (ii) the written consent of the candidate(s) for nomination as a director and verification as to the accuracy of the biographical and other information submitted in support of the candidate; (iii) a resume or other written statement of the qualifications of the candidate(s) for nomination as a director; and, (iv) all information regarding the candidate(s) and the submitting stockholder that would be required to be disclosed in a proxy statement filed with the SEC if the candidate(s) were nominated for election to the Board of Directors. Any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by board members, management or other parties are evaluated.

Any stockholder that wishes to present a director candidate for consideration should submit the information identified above pursuant to the procedures set forth below under “Communication with the Board of Directors.”

PROPOSAL TWO

APPROVAL OF AMENDMENTS TO THE BOKF 2003 STOCK OPTION PLAN

The shareholders of BOK Financial approved the BOKF 2003 Stock Option Plan at the 2003 Annual Meeting of Shareholders. All employees of BOKF and its subsidiaries are eligible to be designated as participants and awarded options under the 2003 Plan. BOKF currently has 3,825 full-time equivalent employees. Participants are designated based upon a subjective determination of the present and potential contributions of the employee to the success of the Company. Except for options intended to comply with Section 162(m) of the Internal Revenue Code, those employees to whom stock option awards are made are selected by the Chairman of the Board of Directors and the Chief Executive Officer. The Board of Directors is proposing for shareholder approval the amendment of the 2003 Plan as follows:

•

Increasing Authorized Shares by 3,500,000. Substantially all of the 2,000,000 shares of common stock currently authorized under the 2003 Plan have been awarded. The Company seeks to increase the number of authorized shares by 3,500,000 so that it may continue to reward outstanding employee performance in accordance with its employee compensation plans.

•

Increasing the Number of Awards that may be Granted to a Single Employee. The 2003 Plan currently limits the number of options that may be granted to a single employee in any one year to 100,000. In order to retain and attract top executives, the Company seeks to increase this limit to allow up to 200,000 options to be granted to a single employee in any one year.

•

Extending the Term of the 2003 Plan. The Company seeks to extend the term of the 2003 Plan until April 30, 2009.

Vote Required

The affirmative vote of the holders of a majority of the shares of common stock, present in person or by proxy, voted at the meeting, is required for approval of the foregoing amendments to the 2003 Plan.

Equity Compensation Plan Information

The following table provides information about the Company’s equity compensation plans in effect at December 31, 2005. Plans included in the following table consist of the BOKF 1994, 1997, 2000, 2001 and 2003 Stock Option Plans, as well as the 2003 Executive Incentive Plan and the BOKF Directors Stock Compensation Plan.

Committees of the Board of Directors

The Risk Oversight and Audit Committee, Independent Compensation Committee and Credit Committee are described below.

Risk Oversight and Audit Committee

During 2005, the Board of Directors of BOK Financial Corporation had a standing Risk Oversight and Audit Committee (the “Audit Committee”) comprised solely of independent directors. The Board of Directors have adopted an Audit Committee charter that complies with Rule 4350(d)(1) of the NASD listing standards. The Audit Committee has the responsibility and authority set forth in Rule 4350(d)(3) of the NASD listing standards under the revised charter. Among other things, the Audit Committee will be responsible for overseeing the accounting and financial reporting processes of the Company and the audits of the financial statements of the Company. The Audit Committee is also

directly responsible for the appointment, compensation, retention and oversight of the work of the Company’s independent auditors, including the resolution of disagreements between management and the auditors regarding financial reporting. Additionally, the Audit Committee approves all related party transactions that are required to be disclosed pursuant to Item 404 of Regulation S-K.

The current members of the Audit Committee are Messrs. Joullian (Chairman), Cadieux, Cappy, Kyle and Malcolm. The Board of Directors has designated Mr. Joullian as its “audit committee financial expert,” as defined in Item 401(h)(2) of Regulation S-K. Mr. Joullian is an “independent director” as defined in Rule 4200(a)(15) of the NASD listing standards. The Audit Committee held five meetings in fiscal 2005 and intends to meet at least five times in fiscal 2006. The Report of the Audit Committee is on page 12 of this proxy statement.

Independent Compensation Committee

In December 2002, the Board of Directors established an Independent Compensation Committee, consisting of independent directors, to administer a performance based compensation plan for senior executives in accordance with the provisions of Section 162(m) of the Internal Revenue Code. The Independent Compensation Committee consists of Messrs. Cappy (Chairman), Griffin and Kyle. Compensation of the Chief Executive Officer, the direct reports to the Chief Executive Officer and other officers participating in the Company’s incentive plan are reviewed by the Independent Compensation Committee. Compensation for all other officers is, in practice, determined by the Chief Executive Officer and Mr. Kaiser, the Chairman of the Board. The Independent Compensation Committee Report on Executive Compensation may be found on page 24 of this proxy statement.

Credit Committee

The purpose of the Credit Committee is to review and report to the Board of Directors regarding the quality of the Company’s credit portfolio and trends affecting the credit portfolio. It also oversees the effectiveness and administration of credit-related policies and reviews the adequacy of the allowance for loan losses and reserve for off-balance sheet credit losses. The members of the Credit Committee are Messrs. Griffin (Chairman), Allen, Boylan, Hargis, Kaiser, LaFortune, Lybarger and Ms. Marshall-Chapman. The Credit Committee met eleven times during fiscal 2005 and plans to meet at least eleven times in fiscal 2006.

Independent Director Meetings

The Board of Directors has adopted a policy of regularly scheduled executive sessions where independent directors will meet separate from management. The independent directors plan to meet in executive session after all regularly scheduled Board of Director meetings. The independent Directors held four executive sessions during 2005. The presiding Director at the executive sessions is Mr. Kaiser. Shareholders of the Company may communicate their concerns to the non-management Directors in accordance with the procedures described below under “Communication with the Board of Directors.”

Communication with the Board of Directors

The Board of Directors of BOK Financial believes that it is important for stockholders to have a process to send communications to the Board.

Report of the Risk Oversight and Audit Committee

The Risk Oversight and Audit Committee (the Committee) oversees the Company’s financial reporting process on behalf of the Board of Directors. In fulfilling its oversight responsibilities, the Committee discussed and reviewed the Company’s consolidated financial statements included in the Annual Report with management and reviewed internal control over financial reporting with management and the internal auditors. This review included discussions with management regarding the quality, not just the acceptability, of accounting policies. It also included the reasonableness of significant judgments, the clarity of disclosures in the consolidated financial statements and the effectiveness of internal control over financial reporting. Management has the primary responsibility for establishing and maintaining internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. The Committee reviewed internal audit reports on the effectiveness of management’s assessment process, discussed internal control matters with management, and reviewed the Company’s compliance with legal and regulatory requirements as necessary.

The Committee discussed and reviewed with Ernst & Young, LLP, the independent registered public accounting firm, their opinion on the conformity of the Company’s consolidated financial statements with accounting principles generally accepted in the United States. This discussion included their judgments as to the quality, not just the acceptability, of the Company’s accounting policies. This discussion covered the required communications under audit standards established by the Public Company Accounting Oversight Board (United States), including PCAOB Auditing Standard No. 2, An Audit of Internal Control over Financial Reporting and Standard No. 61, Communications with Audit Committees. The Committee has reviewed the auditors’ independence and obtained written representation from Ernst & Young, LLP regarding independence matters, in accordance with Independence Standards Board Standard No. 1. In conducting this review, the Committee considered whether any non-audit services were compatible with maintaining the auditor’s independence.

The Committee meets at least quarterly with the Company’s internal auditors and the independent registered public accounting firm regarding the overall scope and plans for their respective audits. These meetings are conducted with and without management present and the Committee discusses the results of the audits, including the auditor’s evaluation of internal control over financial reporting.

Each of the members of the Audit Committee qualifies as an “independent” Director under the current listing standards of the National Association of Securities Dealers (NASD). The Board of Directors has appointed E. Carey Joullian IV as the “audit committee financial expert”.

In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Directors (and the Board has approved) that the audited consolidated financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2005, for filing with the Securities and Exchange Commission.

Represents performance shares in the form of restricted stock issued pursuant to the BOK Financial 2003 Executive Incentive Plan (“Incentive Plan”). Performance shares vest only on the fifth anniversary of the last day of the year for which the shares were issued. Shares may not be sold until three years after the shares vest unless, following such sale, the executive would own that number of shares of BOK Financial common stock provided for in any Executive Management BOKF Common Stock Ownership Guidelines which may be established by the Independent Compensation Committee. The number of performance shares issued in any one year may be increased or decreased based upon two performance measures: 1) Company earnings per share measured against peer group earnings per share and 2) business unit actual controllable value added measured against business unit planned controllable value added and attainment of individually established goals; provided however, that the performance measure for the Chief Executive Officer is based solely on the earnings per share measure. Pre-established performance targets and goals are determined by the Independent Compensation Committee and target achievement measure is based upon a trailing three year average. Individual executive performance shares may be increased in an amount not to exceed 50% of target compensation and decreased to 0% of target compensation based upon a Long Term Incentive matrix established by the Independent Compensation Committee. The determination of whether the number of shares will be increased or decreased for any fiscal year will be determined on the second anniversary of the end of the year in respect of which the performance shares were issued. The value of the performance shares is based upon the market price of BOK Financial common stock on the date of grant.

⁽¹⁾

Options related to compensation for services rendered in 2005 were awarded on four occasions: November 2, 2005 (“Grant #1”); December 2, 2005 (“Grant #2”); December 23, 2005 (“Grant #3”); and, January 6, 2006 (“Grant #4”). Grants 1, 2 and 3 were awarded pursuant to the BOKF 2001 Stock Option Plan; Grant 4 was awarded pursuant to the BOKF 2003 Stock Option Plan.

⁽²⁾ Ÿ

All Grant #1 options vest and become exercisable on November 2, 2007 and expire 45 days after vesting.

All Grant #2 options vest and become exercisable on December 2, 2007, and expire 45 days after vesting.

All Grant #3 options vest and become exercisable on December 23, 2007, and expire 45 days after vesting.

One-seventh of the Grant #4 options vest and become exercisable on January 6 of each year, commencing on January 6, 2007; provided, however, that no options may be exercised until the performance period ends and the Independent Compensation Committee certifies that the pre-established goals were met. Grant #4 vested options expire three years after vesting.

⁽³⁾	Present value at date of grant is based on the Black-Scholes Option Pricing Model adopted for use in valuing exercise stock options based on the following assumptions:

•

Grant #1: 16.8% volatility factor, 3.72% risk free rate of return, $44.00 underlying price, 0.9% dividend yield;

•

Grant #2: 16.8% volatility factor, 3.72% risk free rate of return, $47.99 underlying price, 0.9% dividend yield;

•

Grant #3: 16.8% volatility factor, 3.72% risk free rate of return, $46.18 underlying price, 0.9% dividend yield;

•

Grant #4: 16.8% volatility factor, weighted average 3.69% risk free rate of return, $47.05 underlying price, no dividends.

The actual value, if any, an executive may realize will depend on the excess of the stock price over the exercise price on the date the option is exercised, so there is no assurance the value realized by the named executive will be at or near the value estimated by the Black-Scholes Model.

⁽⁴⁾

Grant #4 Options may be increased or decreased based upon two performance measures: 1) Company earnings per share measured against peer group earnings per share and 2) business unit actual controllable value added measured against business unit planned controllable value added and attainment of individually established goals; provided, however, that the only performance measure for the Chief Executive Officer is the earnings per share measure. Pre-established performance targets and goals are determined by the Independent Compensation Committee and target achievement measure is based upon a trailing three year average. Grant #4 options may be increased in an amount not to exceed 50% of target long term compensation and decreased in amounts to 0% of target long term compensation based upon a Long Term Incentive matrix established by the Independent Compensation Committee. The determination of whether the number of options will be increased or decreased for any fiscal year will be determined on the second anniversary of the end of the year in respect of which the options were issued.

The following table sets forth certain information concerning the exercise of stock options by the Named Executive Officers during fiscal year 2005 and the 2005 fiscal year-end value of unexercised options.

Defined Benefits Plan

Certain executives of the Company participate in the BOK Financial Pension Plan (the “Pension Plan”). The Pension Plan was established in 1987 as a cash balance defined benefit pension plan and has remained substantially unchanged since its inception. Pension Plan benefits are determined based on a hypothetical account balance that accumulates over time. The account balances grow based on a 5.25% interest credit on prior balances plus a monthly account addition based on the executive’s covered pay, age at entry into the plan and years of service. Covered pay includes base salary, shift differential and commissions and excludes incentive compensation and bonuses. Covered pay is limited by government regulations to not more than $210,000. All named executives exceeded this limit for 2005. There is no supplemental plan to make-up for benefits lost due to this government restriction.

During 2005, the Company’s Board of Directors approved curtailment of Pension Plan benefits. Effective April 1, 2006, the hypothetical accounts will no longer be credited for amounts based on covered pay. However, the hypothetical accounts will continue to grow based on the interest credit.

The normal retirement age under the Pension Plan is age 65. At that time, a participant may receive a lump sum equal to the greater of their hypothetical account balance or an amount determined by a government-mandated discount rate. The participant may also elect to receive an annuity payment from the Pension Plan. Various annuity forms are available, but the basic monthly annuity is equal to the hypothetical account balance divided by 200. This annuity amount increases at 5.25% annually over the participant’s life.

The following table indicates the estimated annual basic annuity that will be paid to each executive if they retire at age 65. These amounts are the age 65 annuity values and will increase by 5.25% per year for as long as the executive remains alive. These estimates also assume that each executive will remain employed by the Company and covered by the Pension Plan until their retirement.


Executive	Estimated Annual Basic Benefit at Age 65
Stanley A. Lybarger	$	35,216

C. Fred Ball, Jr.		9,958

Steven G. Bradshaw		16,584

Daniel H. Ellinor		2,571

BOk Thrift Plan

Employee contributions to the BOk Thrift Plan are matched by the Company up to 6% of base compensation, based on years of service. The BOk Thrift Plan also implements a maximum non-executive annual contribution of $750 for certain employees. Participants may direct the investments of their accounts to a variety of options, including BOK Financial common stock.

Employment Agreements with the Named Executives

An evergreen employment agreement is in effect between BOk and Mr. Lybarger. Generally, the agreement provides that Mr. Lybarger will continue to be employed in his present position and at his current rate of compensation. BOk may terminate the employment agreement and be liable for termination benefits not to exceed regular compensation and benefit coverage for twelve months (with termination benefits to be reduced by the amount of compensation received by Mr. Lybarger from other sources during the seventh through twelfth months after termination), any unpaid prior year incentive compensation and a pro-rata share of any current year incentive compensation. In the event of a change of control of BOk, as defined in the employment agreement, Mr. Lybarger has the option, for a period of six months after the change of control, to resign and receive the same termination benefits as described in the preceding sentence in the event of termination by BOk. Further, if, at such time as Mr. Lybarger reaches age 57 he has recruited a Chief Operating Officer that is acceptable to the Chairman of the Board and the Board of Directors, and such COO has completed a minimum of three years of employment with the Company, then, subject to certain other requirements and restrictions, all of Mr. Lybarger’s stock options shall become fully vested upon termination of his employment. Mr. Lybarger has agreed to not compete with the Company for two years following termination.

An employment agreement between BOT and Mr. Ball provides that Mr. Ball will be employed by BOT as its Chairman and Chief Executive Officer until the agreement is terminated by either BOT or Mr. Ball. BOK Financial may terminate without cause subject to payment of agreed annual compensation and benefits for a period not exceeding twelve months. Mr. Ball may terminate the agreement upon twenty-six days prior written notice.

An employment agreement is in effect between BOK Financial and Mr. Bradshaw. The agreement continues until either party terminates the agreement upon ninety days prior written notice and provides for minimum salary and bonus amounts. BOK Financial may terminate the agreement without cause subject to payment of standard severance pay, an amount equal to Mr. Bradshaw’s then current annual salary and other prescribed benefits. BOK Financial may terminate Mr. Bradshaw for cause, in which event Mr. Bradshaw receives salary and bonus through the effective date of termination. Mr. Bradshaw agreed not to solicit Company business for two years following termination for cause and for one year following termination for any other reason.

An employment agreement is in effect between BOK Financial and Mr. Ellinor. The agreement continues until either party terminates the agreement upon ninety days prior written notice and provides for minimum salary and bonus amounts. BOK Financial may terminate the agreement without cause subject to payment of standard severance pay, an amount equal to Mr. Ellinor’s then current annual salary and other prescribed benefits. BOK Financial may terminate Mr. Ellinor for cause, in which event Mr. Ellinor receives salary and bonus through the effective date of termination. Mr. Ellinor agreed not to solicit Company business for two years following termination for cause and for one year following termination for any other reason.

An employment agreement is in effect between BOK Financial and Mr. Pickryl. The initial term began October 15, 2003, and will end on the third anniversary of the commencement date, subject to one year automatic renewals unless either party provides the other written notice of termination ninety days prior the expiration of the initial term or any renewal term. The agreement provides for minimum salary and bonus amounts. In the event BOK Financial terminates Mr. Pickryl without cause, BOK Financial will provide Mr. Pickryl standard severance pay plus an amount equal to two times Mr. Pickryl’s annual salary if termination occurs during the second year and an amount equal to Mr. Pickryl’s annual salary if during the third year and thereafter, that which Mr. Pickryl would otherwise be able to receive under a benefit plan. BOK Financial may terminate Mr. Pickryl for cause, in which event Mr. Pickryl receives

salary and bonus through the effective date of termination. Mr. Pickryl agreed not to compete with certain BOKF subsidiaries or to solicit the Company’s customers for two years after termination of employment for cause and for one year following termination without cause. Mr. Pickryl’s agreement further provides that in the event Mr. Pickryl is terminated without cause between the ages of sixty and sixty-five, the vesting of his options will accelerate. In addition, the Company and Mr. Pickryl have entered into a supplemental Executive Incentive Agreement which provides that Mr. Pickryl will receive supplemental income of $100,000 per year under certain circumstances in the event he continues to be employed by BOK Financial or in the event he is terminated without cause.

Report on Executive Compensation

Independent Compensation Committee

In December 2002, the Board of Directors established an Independent Compensation Committee consisting of independent directors, to administer a performance based compensation plan for senior executives in accordance with the provisions of Section 162(m) of the Internal Revenue Code. The current members of the committee are Messrs. Cappy (Chairman), Griffin and Kyle.

The purpose of the Independent Compensation Committee is to establish performance goals at the beginning of each fiscal year and award incentive compensation under the BOK Financial Corporation 2003 Executive Incentive Plan, approved by shareholders at the 2003 Annual Meeting of Shareholders. The goals of the Independent Compensation Committee are to help the Company compete with peer institutions in attracting and retaining highly qualified individuals as executive officers, to pay executive officers based upon their contributions to the Company’s performance, and to comply with Section 162(m) of the Internal Revenue Code.

Section 162(m) of the Internal Revenue Code limits deductibility for federal income tax purposes of compensation in excess of $1,000,000 annually paid to individual executive officers including compensation based on performance goals, unless certain requirements are met. The BOK Financial Corporation 2003 Executive Incentive Plan was established and is maintained to comply with the performance-based exception to limits on deductibility of executive officer compensation. The Chief Executive Officer, executives who report directly to the Chief Executive Officer and other selected officers approved by the Independent Compensation Committee may participate in the Plan.

The Independent Compensation Committee uses a twenty-six bank peer group to set target compensation, annual performance goals for bonus and long term incentive compensation and manner of payment of long term incentive compensation for each participant on an individual basis. The performance goals for 2005 were based on a combination of (i) Company earnings per share measured against peer group earnings per share and (ii) business unit performance and attainment of individual goals. The Independent Compensation Committee believes that basing executive compensation on earnings per share performance strengthens the alignment of the interests of the executive officers with those of all stockholders, while business unit performance measures promote individual productivity and leadership. The Committee reviewed and approved the calculation of annual and long-term compensation paid pursuant to the 2005 goals.

The Independent Compensation Committee noted that the Company performed exceptionally well as it recorded record earnings in 2005. The Committee believes that the compensation paid during 2005 was fair and reasonable and served the long term interests of the Company.

INDEPENDENT COMPENSATION COMMITTEE

Joseph E. Cappy, Chairman

David E. Griffin

David L. Kyle

Informal Compensation Committee

Compensation for officers other than the Chief Executive Officer, the direct reports to the Chief Executive Officer and the other officers reviewed by the Independent Compensation Committee is, in practice, determined by the Chief Executive Officer and Mr. Kaiser, the Chairman of the Board.

Compensation Committee Interlocks and Insider Participation

None of the members of the Independent Compensation Committee were at any time officers or employees of the Company or any of its subsidiaries or had any relationship with the Company requiring disclosure under the Securities and Exchange Commission regulations. Messrs. Kaiser and Lybarger make up the Informal Compensation Committee which administers all compensation not reviewed by the Independent Compensation Committee. See “Report of Executive Compensation” and “Certain Transactions.”

Certain Transactions

Certain principal shareholders, directors of the Company and their associates were customers of and had loan transactions with BOK Financial or its subsidiaries during 2005. None of them currently outstanding are classified as nonaccrual, past due, restructured or potential problem loans. All such loans (i) were made in the ordinary course of business, (ii) were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons, and (iii) did not involve more than normal risk of collectibility or present other unfavorable features at the time the loans were made.

Certain related parties are customers of the Company for services other than loans, including consumer banking, corporate banking, risk management, wealth management, brokerage and trading, or fiduciary/trust services. The Company engages in transactions with related parties in the ordinary course of business and in compliance with applicable regulation.

BOk leases office space in the Copper Oaks facility located in Tulsa, Oklahoma, which is owned by Mr. Kaiser and affiliates. Lease payments for Copper Oaks totaled $754,704 in 2005.

In 2005, an affiliate of BOK Financial sold Oklahoma State Income Tax Credits to (a) George Kaiser, Chairman of the Board, receiving $16,283,400, (b) Jim Holloman, executive officer, receiving $30,000, (c) Stan Lybarger, Chief Executive Officer, receiving $64,600, (d) Ruth Nelson Trust, receiving $250,000, (e) Burns Hargis, a Company director and executive officer, receiving $30,000; and, (f) Mark Funke, an executive officer, receiving $15,000. Ms. Ruth Nelson is Mr. Kaiser’s sister.

QuikTrip Corporation has entered into a fee sharing agreement with TransFund, BOk’s automated teller machine (ATM) network, respecting transactions completed at TransFund ATMs placed in QuikTrip locations. In 2005, BOk paid QuikTrip $1.3 million pursuant to this agreement. Mr. Cadieux, a BOK Financial Director, is President, Chief Executive Officer, a director and a shareholder of QuikTrip Corporation.

BOk engages in routine energy hedging transactions with Mustang Fuel Corporation, Mustang Gas Products, LLC and Eagle Gas Marketing on terms offered to customers of BOk generally. In 2005, Mustang Fuel Corporation hedged 1 million MMbtu of natural gas and 10,000 barrels of oil, Eagle Natural Gas hedged 66,300 MMbtu of natural gas, and Mustang Gas Products, LLC hedged 10,250,000 gallons of natural gas liquids. The hedges are backed by counter party contracts. Mr. Joullian, a director of BOK Financial, is the President of Mustang Fuel Corporation, Mustang Gas Products, LLC and Eagle Gas Marketing.

Controlled Company Exemption

The Board of Directors has determined that BOK Financial is a “controlled company,” as defined in Rule 4350(c)(5) of the listing standards of the National Association of Securities Dealers, Inc. (“NASD”), based on Mr. Kaiser’s beneficial ownership of approximately 66.7% of the outstanding common stock. Accordingly, BOK Financial is exempt from certain requirements of the NASD listing standards, including the requirement to maintain a majority of independent directors on the Company’s Board of Directors and the requirements regarding the determination of compensation of executive officers and the nomination of directors by independent directors. Nevertheless, the Company does maintain a substantial majority of independent directors, determines upper level management compensation through an independent board committee and nominates new board members through board consensus.

Insider Reporting Update

Based upon a review of the filings with the Securities and Exchange Commission and written representations that no other reports were required, we believe that all of our directors and executive officers complied during fiscal year 2005 with the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934 with the exception of a late report in March 2005 relating to 1,000 shares sold in February 2005 for Mr. Funke; a late report in November 2005 relating to 16,814 shares acquired and 10,446 shares disposed of through the exercise of stock options and a report in February 2006 relating to 1,577 shares sold in November 2005 for Mr. Hargis; a late report in November 2005 relating to 724 shares acquired and 348 shares disposed of through the exercise of stock options for Mr. Ralston; and a late report in December 2005 relating to 1,282 shares acquired through the exercise of stock options in December 2005 for Mr. Cotter.

Independent Public Accountants

Ernst & Young LLP, independent public accountants, has been reappointed by the Board of Directors of the Company as independent auditors for the Company to examine and report on its financial statements for 2006. Ernst & Young LLP have been auditors of the accounts of the Company since its inception on October 24, 1990. Representatives of Ernst & Young LLP are expected to be present at the annual meeting, with the opportunity to make a statement if they desire to do so, and will be available to respond to appropriate questions.

The Board of Directors will consider proposals of shareholders intended to be presented for action at the Annual Meeting of Shareholders. According to the rules of the Securities and Exchange Commission, such proposals shall be included in the Company’s Proxy Statement if they are received in a timely manner and if certain other requirements are met. For a shareholder proposal to be included in the Company’s Proxy Statement relating to the 2007 Annual Shareholders’ Meeting, a written proposal

complying with the requirements established by the Securities and Exchange Commission must be received at the Company’s principal executive offices, located at Bank of Oklahoma Tower, Tulsa, Oklahoma 74172, no later than December 1, 2006.

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:

3.2.1

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 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.

3.2.4

A 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. Kaiser, affiliates of George B. Kaiser, or members of the family of George B. Kaiser); or,

3.2.4.2

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

3.2.6

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).

3.3

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 therefore, 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.

The Corporation’s general counsel shall determine whether the Participant is an affiliate or a non-affiliate of BOKF.
