We are sending you this document to ask you to vote "FOR" the merger and to approve certain payments to three Bank of Tanglewood executives under existing compensation arrangements with such executives. The special meeting will be held on Thursday, October 24, 2002 at 10:00 a.m., central time, at the Houston Country Club, located at One Potomac Drive, Houston, Texas. BOK Financial has agreed to issue $65,000,000 (less transaction costs of $450,000) in BOK Financial common stock to the shareholders and stock option holders of Bank of Tanglewood. Of this $64,550,000 of BOK Financial common stock, approximately $750,000 of BOK Financial common stock will be placed into escrow for possible future distribution to former Bank of Tanglewood shareholders and stock option holders as further described on pages 42 and 43. Because the market value of BOK Financial common stock fluctuates, you will not know at the time you vote on the merger the exact number of shares of BOK Financial common stock you will receive for your Bank of Tanglewood common stock. However, using the average trading price of BOK Financial common stock for the 30 trading days ending on September 17, 2002 of $32.84 by way of example, Bank of Tanglewood shareholders or option holders would be entitled to receive, or exercise options to purchase, 1.72 shares of BOK Financial common stock for each share of Bank of Tanglewood common stock. BOK Financial has also agreed to provide assurance, subject to limitations further described on pages 40 and 41, that the market value of 50% of the BOK Financial common stock received in the transaction will increase by 8% per year for five years. Such amount will not be compounded. The remaining 50% of the shares of BOK Financial common stock received by Bank of Tanglewood shareholders and option holders will not be protected and will be subject to the same price fluctuations as any other share of BOK Financial common stock. Bank of Tanglewood shareholders are also being asked to approve the payment of an aggregate of $277,805 to three Bank of Tanglewood executives under existing compensation agreements with such executives in order to avoid adverse tax consequences. Approval of these payments will not effect the value or number of shares of BOK Financial common stock you will receive in the merger. BOK Financial common stock is listed on the NASDAQ Stock Market National Market System under the symbol "BOKF." An investment in BOK Financial common stock in connection with the merger involves risks. See "Risk Factors" beginning on page 6 of this document. Neither the Securities and Exchange Commission, the Office of the Comptroller of the Currency, the Federal Reserve Board nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this document. Any representation to the contrary is a criminal offense. The securities offered through this document are not savings accounts, deposits or other obligations of a bank or savings association and are not insured by the Federal Deposit Insurance Corporation or any other government agency. (continued on reverse side) If the merger were completed as of September 17, 2002, a total of 1,658,411 shares of BOK Financial common stock would be issued to Bank of Tanglewood shareholders, not including 287,154 shares of BOK Financial common stock reserved for the exercise of Bank of Tanglewood stock options, and 22,838 shares of BOK Financial common stock that would be deposited into escrow. Excluding the option shares and the escrow shares, Bank of Tanglewood shareholders would own approximately 3.13% of BOK Financial common stock outstanding after the merger. Your vote is very important. We cannot complete the merger unless the holders of two-thirds of Bank of Tanglewood common stock approve it. We cannot make the executive payments unless the holders of 75% of the outstanding shares of Bank of Tanglewood common stock (excluding shares held by such executives and certain of their family members) approve it. The accompanying proxy statement-prospectus contains answers to frequently asked questions and a summary description of the merger, followed by a more detailed discussion of the merger and related matters. In addition, you may obtain information about BOK Financial from documents that BOK Financial has filed with the Securities and Exchange Commission. We urge you to review carefully this entire document. /s/ Richard W. Jochetz Richard W.

QUESTIONS AND ANSWERS ABOUT THE MERGER Q: Why are Bank of Tanglewood and BOK Financial proposing the merger? A: Our companies are proposing the merger because we believe that the combined company will be a more effective competitor and will provide future growth opportunities. BOK Financial offers products and services that Bank of Tanglewood does not or cannot offer due to the smaller size of Bank of Tanglewood. Bank of Tanglewood provides a customer base previously unavailable to BOK Financial. Please read the more detailed description of our reasons for the merger on pages 22 and 23. Q: What will I receive in exchange for my Bank of Tanglewood shares in the merger? A: BOK Financial has agreed to issue $65,000,000 (less transaction costs of $450,000) in BOK Financial common stock to the shareholders and stock option holders of Bank of Tanglewood. Of this $64,550,000 of BOK Financial common stock, approximately $750,000 of BOK Financial common stock will be placed into escrow for possible future distribution to former Bank of Tanglewood shareholders and stock option holders as further described on pages 42 and 43. Because the market value of BOK Financial common stock fluctuates, you will not know at the time you vote on the merger the exact number of shares of BOK Financial common stock you will receive for your Bank of Tanglewood common stock. However, using the average trading price of BOK Financial common stock for the 30 trading days ending on September 17, 2002 of $32.84 by way of example, Bank of Tanglewood shareholders and option holders would be entitled to receive, or exercise options to purchase, 1.72 shares of BOK Financial common stock for each share of Bank of Tanglewood common stock. BOK Financial has also agreed to provide assurance, subject to limitations further described on pages 40 and 41, that the market value of 50% of the BOK Financial common stock received in the transaction will increase by 8% per year for five years. Such amount will not be compounded. The remaining 50% of the shares of BOK Financial common stock received by Bank of Tanglewood shareholders and option holders will not be protected and will be subject to the same price fluctuations as any other share of BOK Financial common stock. Q: What are the executive payments and why am I being asked to approve them? A: Bank of Tanglewood has various agreements and plans to provide compensation to its officers and employees. These include the Bank of Tanglewood 1996 Stock Option Plan and the Phantom Stock Agreements between Bank of Tanglewood and 11 of its officers. A change in control of the bank, such as the merger, causes rights under the plans and agreements to mature or vest at the time of the change of ownership, rather than pursuant to the normal vesting schedule provided for in the various agreements. As a result, three executive officers of Bank of Tanglewood will receive cash payments in connection with the merger that exceed certain limits under federal income tax laws. Federal income tax law provides that such payments made to executives in connection with a change of ownership of the bank (such as the merger) in excess of certain amounts are characterized as "parachute payments". This characterization results in the loss of the tax deduction by Bank of Tanglewood with respect to amounts in excess of a defined base amount and subjects such executives to a 20% excise tax on the excess amount. The payments will not be characterized as "parachute payments" if the executives' right to receive these excess payments is approved by the holders of more than 75% of the outstanding shares of Bank of Tanglewood common stock (not including shares of such executives and certain other shareholders related to the executives). Consequently, to avoid the adverse tax consequences, the three executives (Messrs. Greer, Jochetz and Tidwell) have waived their rights to receive a portion of the amount each executive would be entitled to receive upon consummation of the merger ($277,805 in total) unless approved by the shareholders. The amount of the payment each executive has waived reduces their respective payments to a level where there are no excise taxes or lost corporate deductions. Approval of these payments will not effect the value or number of shares of BOK Financial common stock you will receive in the merger. QA-1 For further details regarding the executive payments and the amounts due under compensation plans and agreements, see "Proposal II -- Voting On Executive Payments" on page 49. Q: When do you expect the merger to be completed? A: We currently anticipate that the closing of the merger will occur on or about October 25, 2002, but this is subject to change. Q: How does the board of directors recommend that I vote? A: Our board of directors, by a unanimous vote, has approved and adopted the merger agreement and the merger and recommends that the shareholders vote FOR approval of the merger. The board of directors believes that the merger is fair to, and in the best interests of, our shareholders. The board of directors (with Messrs. Greer, Jochetz and Tidwell abstaining) also recommends that you vote FOR approval of the executive payments in the aggregate amount of $277,805 pursuant to the existing compensation arrangements with Messrs. Greer, Jochetz and Tidwell. Q: What happens if I transfer my shares after the record date? A: The record date for the special meeting is earlier than the expected date of the merger. Therefore, if you transfer your shares of common stock after the record date, but prior to the merger, you will retain the right to vote at the special meeting, but the right to receive the merger consideration will transfer with the shares of stock. Q: Will I have to pay taxes as a result of the merger? A: Generally no, except with respect to the benchmark price protection rights. Because the merger qualifies as a tax free reorganization under the Internal Revenue Code, no gain or loss will be recognized by holders of Bank of Tanglewood common stock who exchange their Bank of Tanglewood common stock solely for BOK Financial common stock. However, you will have to recognize capital gain to the extent of the value of the benchmark price protection rights that you receive. Also, if you dissent from the merger and are paid the fair value of your stock in cash, you will be subject to tax on the cash payments. See "Material U.S. Federal Income Tax Consequences" on page 24. Q: What do I need to do to vote? A: Mail your signed proxy in the enclosed return envelope as soon as possible so that your shares may be represented at the special meeting. Q. May I vote in person? A: Yes. You may attend the special meeting and may vote your shares in person, rather than signing and mailing a proxy. However, in order to assure that we obtain your vote, please vote as instructed on your proxy even if you currently plan to attend the special meeting in person. Q: May I change my vote even after returning a proxy? A: Yes. If you want to change your vote, you may do so at any time before the Bank of Tanglewood special meeting by sending to the Secretary of Bank of Tanglewood a proxy with a later date. Alternatively, you may revoke your proxy by delivering to the Secretary of Bank of Tanglewood a written revocation prior to the special meeting or by voting in person at the special meeting. If your shares are held in "street name" with a bank or broker, you must contact your bank or broker if you wish to revoke your proxy. QA-2 Q: What happens if I don't return a proxy or vote? A: If a Bank of Tanglewood shareholder does not submit a proxy or vote at the Bank of Tanglewood shareholder meeting, it will have the same effect as a vote against adoption and approval of the merger agreement and the merger and a vote against approval of payment of the compensation to certain executives. Q: Should I send in my Bank of Tanglewood stock certificates now? A: No. After the merger is completed, we will send written instructions that will explain how to exchange Bank of Tanglewood stock certificates for BOK Financial common stock. Please do not send your stock certificates with your proxy. Q: When will I receive my shares BOK Financial common stock? A: You will receive all of your shares of BOK Financial common stock, except your proportionate share of the $750,000 worth of shares of BOK Financial common stock to be deposited in escrow, as soon as practicable after you have surrendered your Bank of Tanglewood stock certificates to the transfer agent in accordance with the stock transfer letter. You will receive your proportionate number of the shares of BOK Financial common stock deposited in escrow upon the termination of the escrow account, which shall be the later of December 31, 2003 or the date on which all claims under the escrow have been resolved. Q: Do I have any rights to avoid participating in the merger? A. Yes. You have the right to withhold your vote for the merger, dissent from the merger and seek appraisal value for your shares. The appraised value may be more or less than the value of the BOK Financial common stock being paid in the merger. In order to preserve your dissenters' rights, you must follow strictly the provisions of the National Bank Act and the Office of the Comptroller of the Currency's regulations regarding dissenters' rights. For further description of these rights, see page 27 and Annex IX, which contains a copy of the applicable provisions of the National Bank Act and the OCC Banking Circular explaining dissenters' rights and procedures. Q: If I have more questions about the merger, voting or BOK Financial or Bank of Tanglewood, how can I find answers? A: In addition to reading this document and its annexes, you can find more information about BOK Financial in filings it has previously made with the Securities and Exchange Commission. BOK Financial incorporates by reference into this document its filings with the SEC. See "Where You Can Find More Information" on page 88. You may also contact James F.

Each item in this summary includes a page reference directing you to a more complete description of that item. We have included the merger agreement, as amended, as Annex I to this document. It is the legal document that governs the merger and we encourage you to read it. The Companies (pages 77 and 85) Bank of Tanglewood, N.A. 500 Chimney Rock Road Houston, Texas 77056-1220 (713) 226-2900 Bank of Tanglewood, N.A. is a national banking association organized under the banking laws of the United States. Bank of Tanglewood conducts its banking business at three locations in the Houston area including its branches operating under the names Bank of West University and Bank of Memorial. Bank of Tanglewood has 51 full-time equivalent employees and provides business and personal banking, as well as investment services. At June 30, 2002, Bank of Tanglewood had total assets of $234.3 million, total deposits of $204.7 million and total shareholders' equity of $17.2 million. BOK Financial Corporation Bank of Oklahoma Tower Boston Avenue at Second Street Tulsa, Oklahoma 74172 (918) 588-6000 BOK Financial was incorporated under the laws of the State of Oklahoma in 1990 and is a bank holding company under the Bank Holding Company Act of 1956. BOK Financial owns, directly or indirectly, all of the outstanding capital stock of Bank of Oklahoma, N.A., Bank of Texas, N.A., Bank of Albuquerque, N.A., Bank of Arkansas, N.A. and BOSC, Inc. BOK Financial is listed on NASDAQ under the symbol "BOKF." It offers, through its subsidiaries, commercial banking services, investment securities and money market services, mortgage banking, trust and asset management services and electronic funds transfer. BOK Financial and its subsidiaries have approximately 3,400 full-time equivalent employees at 72 locations in Oklahoma, 21 locations in Texas, 18 locations in Albuquerque, New Mexico and 3 locations in Arkansas. At June 30, 2002, BOK Financial had total assets of $11.2 billion, total deposits of $7.2 billion and total shareholders' equity of $924.4 million. TW Interim National Bank 500 Chimney Rock Road Houston, Texas 77056-1220 (713) 226-2900 TW Interim National Bank is a wholly owned subsidiary of BOK Financial, formed as an interim national bank pursuant to the National Bank Act. Since its creation, TW Interim has not carried on any activities, other than in connection with the merger. The Merger (page 21) We propose a merger transaction in which Bank of Tanglewood will merge into TW Interim National Bank, a wholly owned subsidiary of BOK Financial. BOK Financial contemplates that the merged Tanglewood/TW 1 Interim entity will promptly be merged into Bank of Texas, N.A., another wholly owned subsidiary of BOK Financial. Bank of Tanglewood's Financial Advisor Has Opined that the Merger is Fair to Shareholders (page 29) On May 9, 2002, Hovde Financial, LLC, Bank of Tanglewood's financial advisor, delivered to the Bank of Tanglewood board its preliminary written opinion as to the fairness, from a financial point of view, of the merger consideration to the holders of Bank of Tanglewood common stock. The written opinion was accompanied by an oral presentation to the Bank of Tanglewood board of directors regarding the fairness of the transaction, from a financial perspective. We have attached Hovde's opinion, as reviewed and updated, dated September 20, 2002 as Annex VIII to this document. We urge you to read this opinion in its entirety to understand the assumptions made and matters considered by Hovde in rendering its opinion. Hovde provided its opinion to Bank of Tanglewood's board of directors for its use and benefit and such opinion addresses only the fairness, from a financial point of view as of the date of the opinion, of the merger consideration to the holders of Bank of Tanglewood common stock. The Hovde opinion is not a recommendation to any Bank of Tanglewood shareholder as to how that shareholder should vote at the special meeting. Recommendation of Bank of Tanglewood's Board to Shareholders (page 23) The board of directors of Bank of Tanglewood believes that the merger is fair to you and in your best interests and unanimously recommends that you vote FOR the proposal to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger. All the members of the Bank of Tanglewood board of directors are independent and not otherwise employed by or affiliated with Bank of Tanglewood except Messrs. Greer, Jochetz and Tidwell. The members of the Bank of Tanglewood board of directors (with Messrs. Greer, Jochetz and Tidwell abstaining) also recommend that you vote FOR the proposal to approve payments in the amount of $277,805 pursuant to the existing compensation arrangements with Messrs. Greer, Jochetz and Tidwell. Approval of these payments will not effect the value or number of shares of BOK Financial common stock you will receive in the merger. Management and Operations after the Merger (page 35) After the merger, the resulting entity will be called Bank of Tanglewood, N.A., will be headquartered in Houston, Texas and will be a wholly owned subsidiary of BOK Financial. The officers and directors of Bank of Tanglewood will be the officers and directors of the surviving bank until changed as provided by law. Upon consummation of the merger, BOK Financial shall cause Robert G. Greer, Chairman of the board of directors of Bank of Tanglewood, to be elected as advisory director of BOK Financial and thereafter, to be nominated for election as a voting director of BOK Financial at BOK Financial's 2003 annual meeting of shareholders. Mr. Greer will also be elected to the Bank of Texas, N.A. board of directors, which is a wholly owned subsidiary of BOK Financial. BOK Financial contemplates that the merged Tanglewood/TW Interim entity will be merged into Bank of Texas, N.A. The subsequent merger into Bank of Texas is also planned for the fourth quarter of 2002, but delays could occur. Some of the Officers and Directors of Bank of Tanglewood have Financial Interests in the Merger that Differ from Your Interests (page 36) In considering the recommendation of the Bank of Tanglewood board to vote in favor of the merger and the executive payments, you should be aware that certain officers and directors of Bank of Tanglewood have 2 financial interests in the merger that may be different from, or in addition to, your interests as a shareholders. These interests include: . rights under the Phantom Stock Agreements between Bank of Tanglewood and 11 of its executive officers (including Messrs. Greer, Jochetz and Tidwell) will accelerate and become fully vested upon completion of the merger; . certain of Bank of Tanglewood's officers hold options to purchase shares of Bank of Tanglewood common stock, which will accelerate and become fully vested at the completion of the merger. These options will convert into options to acquire shares of BOK Financial common stock, subject to the escrow account, and must be exercised by such officers no later than 120 days following completion of the merger. In addition, the option holders will receive cash payments from Bank of Tanglewood in connection with exercising their options to partially offset tax liabilities they will incur; . certain officers and directors of Bank of Tanglewood have entered into employment and non-competition/non-solicitation agreements with BOK Financial; . BOK Financial has agreed to elect Mr. Greer as an advisory member of the BOK Financial board of directors and to nominate him to be a voting director at the 2003 BOK Financial annual shareholders meeting. Mr. Greer is also to be elected as a member of the Bank of Texas, N.A. board of directors after completion of the merger; and . the right of Bank of Tanglewood's directors and officers to continued indemnification and insurance coverage by BOK Financial for acts or omissions occurring prior to completion of the merger. Members of Bank of Tanglewood's Management are Expected to Vote Their Shares For Approval of the Merger Agreement and the Payments to Certain Executives (page 18) As of September 20, 2002, the record date, directors, executive officers and affiliates of Bank of Tanglewood, certain of their family members and entities they control were entitled to vote 160,531 shares, or approximately 16.42%, of the outstanding shares of Bank of Tanglewood common stock. No director, executive officer or affiliate of BOK Financial owns any shares of Bank of Tanglewood common stock. Shares of Bank of Tanglewood common stock held by Messrs. Greer, Jochetz and Tidwell (and certain family members), which total 40,804 shares, or approximately 4.17%, of the outstanding shares of Bank of Tanglewood common stock, may not be voted in connection with the proposal to approve the payments which have been waived by such executives and will not be counted as outstanding with regard to such proposal. As of September 20, 2002, Bank of Tanglewood had 977,470 shares of common stock outstanding. The Distribution of a Portion of the Shares of BOK Financial Common Stock to be Issued in the Merger is Subject to the Terms of an Escrow Agreement (page 42) Of the shares of common stock that BOK Financial will issue in the merger, shares of BOK Financial common stock with an aggregate value of $750,000 will be deposited into an escrow account to compensate BOK Financial for any breaches in representations and warranties of Bank of Tanglewood which are discovered between completion of the merger and December 31, 2003. Upon termination of the escrow account, the Bank of Texas Trust Department, as escrow agent, will distribute to the former Bank of Tanglewood shareholders and exercising option holders the escrowed shares remaining after the deduction of any losses related to a breach. Each Bank of Tanglewood shareholder will receive his or her pro rata share of any distribution of remaining escrowed shares and any dividends paid with respect to such escrowed shares. No fractional shares shall be placed into escrow, and any fractional share will be rounded up to a whole share of BOK Financial common stock and will be placed into the escrow. If the merger is approved, you will be bound by the terms of the escrow agreement whether or not you vote in favor of the merger. Under the terms of the merger agreement, the Bank of Tanglewood agent, who may be 3 removed at any time by a majority vote of the former Bank of Tanglewood shareholders, will make decisions on behalf of the former Bank of Tanglewood shareholders and exercising option holders related to the disposition of the shares held in escrow and will vote the shares in any action requiring a vote of BOK Financial shareholders. Further, the merger agreement provides that the Bank of Tanglewood agent will be liable to the Bank of Tanglewood shareholders and exercising option holders only as a result of gross negligence or intentional wrongdoing. While the shares are held in escrow, the Bank of Tanglewood shareholders will not receive any cash or stock dividends paid with respect to the shares until such time, if any, that the shares are released from the escrow. However, former Bank of Tanglewood shareholders will be taxed on any cash dividends paid during the escrow period. See "Material U.S. Federal Income Tax Consequences" on page 24. The rights of Bank of Tanglewood shareholders under the escrow agreement are not transferable other than by will or by the laws of descent and distribution.

No Solicitation (page 46) Bank of Tanglewood has agreed not to: . solicit or encourage inquires or proposals with respect to the merger of Bank of Tanglewood or the sale of any of the shares of Bank of Tanglewood stock or other material asset(s) of Bank of Tanglewood from any party other than BOK Financial; or . to merge with any party or sell any of the shares of the Bank of Tanglewood stock or material asset(s). However, Bank of Tanglewood may have discussions and negotiations with another party regarding a merger or share or asset sale if the Bank of Tanglewood board of directors determines in good faith that the failure to take such action could constitute a breach of the fiduciary duties of the board of directors or as necessary to comply with regulatory requirements. Termination of the Agreement (page 48) Bank of Tanglewood and BOK Financial may, by mutual agreement, terminate the merger agreement at any time, even after the shareholders of Bank of Tanglewood have approved the merger. In addition, either party may terminate the merger agreement if: . the conditions to closing have not been fulfilled or waived on or prior to closing; . the merger has not been completed on or before December 31, 2002; or . there is a material breach of the merger agreement. Regulatory Approvals (page 24) We were required to, and have received, approval for the merger from the Office of the Comptroller of the Currency, the Federal Reserve Board and the Texas Department of Banking. Your Rights as a Shareholder of BOK Financial will be Different than as a Shareholder of Bank of Tanglewood (page 51) BOK Financial is an Oklahoma corporation and the rights of its shareholders are governed by Oklahoma law and its certificate of incorporation and bylaws. Bank of Tanglewood is a national banking association and the rights of its shareholders are governed by the National Bank Act, Texas law and its articles of association and bylaws. Upon completion of the merger, Bank of Tanglewood shareholders will become shareholders of BOK Financial and their rights will be governed by BOK Financial's certificate of incorporation and bylaws and Oklahoma law. BOK Financial's certificate of incorporation and bylaws will remain the same unless altered, amended or repealed in the future. 5 RISK FACTORS In deciding whether to approve the merger and the executive payments, you should carefully read this proxy statement-prospectus and the accompanying documents to which we refer you. You should also carefully consider the risks described below before making a decision to approve the merger. The risks and uncertainties described below are not the only ones relating to the merger or facing BOK Financial. Additional risks and uncertainties not currently known to BOK Financial or that it currently deems immaterial may also adversely effect its business and operations. RISKS RELATING TO THE MERGER BOK Financial shares to be received by Bank of Tanglewood shareholders in the merger will fluctuate in value. The market price of the BOK Financial common stock to be issued in the merger may change following the merger as a result of changes in BOK Financial's business, operations or prospects, market assessments of the impact of the merger or general market conditions. Although the merger agreement provides that the market value of 50% of the BOK Financial common stock you receive in to the merger will increase by 8% per year for five years, this protection is subject to certain limitations and restrictions as further described in "Benchmark Price Protection" on page 41. Further, the other 50% of the BOK Financial common stock you receive will have no form of benchmark price protection and there can be no assurance as to their value following the merger. BOK Financial may experience difficulties in integrating Bank of Tanglewood's business with the existing business of BOK Financial subsidiaries, which could cause BOK Financial to lose many of the anticipated potential benefits of the merger. BOK Financial entered into the merger agreement with Bank of Tanglewood because it believes that the merger will be beneficial to the combined company. Achieving the anticipated benefits of the merger will depend in part upon whether BOK Financial can integrate the businesses of its subsidiary, Bank of Texas, and Bank of Tanglewood in an efficient and effective manner. BOK Financial may not be able to accomplish this integration process smoothly or successfully. The necessity of coordinating geographically separated organizations and addressing possible differences in technologies, corporate cultures and management philosophies may increase the difficulties of integration. The integration of certain operations following the merger will require the dedication of significant management resources, which may temporarily distract management's attention from the day-to-day business of the combined companies. Employee uncertainty and lack of focus during the integration process may also disrupt the business of the combined companies. Any inability of BOK Financial management to integrate successfully the operations of Bank of Tanglewood into Bank of Texas could have an adverse effect on the business, results of operations and financial condition of BOK Financial. There are no assurances that Bank of Tanglewood shareholders will receive any of the $750,000 in shares of BOK Financial common stock to be held in escrow, yet you will have to pay taxes with respect to any cash dividends accrued on these shares. Bank of Tanglewood has agreed to put into escrow, on behalf of Bank of Tanglewood shareholders and option holders, a portion of the shares of BOK Financial common stock to be issued in the merger having a market value of $750,000. The Trust Department of Bank of Texas, acting as escrow agent, will hold these shares to compensate BOK Financial for losses that may be incurred by BOK Financial resulting from the discovery of a breach by Bank of Tanglewood of any of its representations and warranties made in the merger agreement during the period beginning at the completion of the merger and ending on December 31, 2003. As a result, you may receive only a portion, or none, of the $750,000 in the shares of BOK Financial common stock held in escrow. 6 In addition, for the period from the completion of the merger through December 31, 2003 during which your portion of escrowed shares will be held in the escrow, you will be required to recognize as income for federal income tax purposes an amount equal to any cash dividends which accrue on your shares and interest earned on such amounts in the tax year in which the dividends are paid into the escrow, even though you will not receive these amounts until a later date, if at all. Although BOK Financial has never paid a cash dividend in the past, there is no assurance that it will not pay a cash dividend during the period in which the escrow is in effect. As a result, any dividend payments and interest earned on such amounts are likely to result in ordinary income, and a related tax liability, even though you will only receive the dividends if and when you receive the related escrowed shares. Further, you may not transfer your interest in these escrowed shares other than by will or the laws of descent and distribution. Therefore, you would be subject to the same tax liability even if after the merger you sell all of the shares of Bank of Tanglewood common stock that you received in the merger. You will have less influence as a shareholder of BOK Financial than as a shareholder of Bank of Tanglewood. As a Bank of Tanglewood shareholder, you currently have the right to vote in the election of the board of directors of Bank of Tanglewood and on other matters affecting Bank of Tanglewood. The merger will transfer control of Bank of Tanglewood to BOK Financial and to the shareholders of BOK Financial. When the merger occurs, you will become a shareholder of BOK Financial with a percentage ownership much smaller than your percentage ownership of Bank of Tanglewood. If the merger were completed as of September 17, 2002, based on an assumed conversion ratio of 1.72, a total of 1,658,411 shares of BOK Financial common stock would be issued to Bank of Tanglewood shareholders upon completion of the merger and 22,838 shares of BOK Financial common stock would be deposited into the escrow account. As a result, Bank of Tanglewood shareholders would own approximately 3.13% of BOK Financial common stock outstanding after the merger. In addition, 287,154 shares of BOK Financial common stock will be reserved for issuance pursuant to the exercise of converted Bank of Tanglewood stock options. Because of this, you will have less influence on the management and policies of BOK Financial than you now have on the management and policies of Bank of Tanglewood. RISKS RELATING TO BOK FINANCIAL Adverse regional economic developments could negatively affect BOK Financial's business. A substantial majority of BOK Financial loans are generated in Oklahoma and other markets in the southwest region, with approximately 73% of 2001 earnings derived from activities in the state of Oklahoma. As a result, poor economic conditions in Oklahoma or other markets in the southwest region may cause BOK Financial to incur losses associated with higher default rates and decreased collateral values in BOK Financial's loan portfolio. A regional economic downturn could also adversely affect revenue from brokerage and trading activities, mortgage loan originations and other sources of fee-based revenue. Adverse economic factors affecting particular industries could have a negative effect on BOK Financial customers and their ability to make payments to BOK Financial. Certain industry-specific economic factors also affect BOK Financial. For example, as of year-end 2001, 16% of BOK Financial's total loan portfolio was comprised of loans to borrowers in the energy industry and 3% of BOK Financial's total loan portfolio was comprised of loans to borrowers in the agricultural industry, both of which are historically cyclical industries. Low commodity prices may adversely affect those industries and, consequently, may affect BOK Financial's business negatively. In addition, as of year-end, 2001, 21% of BOK Financial's total loan portfolio was comprised of commercial real estate loans. A downturn in the real estate industry in Oklahoma and the Southwest region could also have an adverse effect on BOK Financial's operations. 7 Fluctuations in interest rates could adversely affect BOK Financial's business. BOK Financial's business is highly sensitive to: . the monetary policies implemented by the Federal Reserve Board, including the discount rate on bank borrowings and changes in reserve requirements, which affect BOK Financial's ability to make loans and the interest rates we may charge; . changes in prevailing interest rates, due to the dependency of BOK Financial's banks on interest income; and . open market operations in U.S. Government securities. Significant increases in market interest rates, or the perception that an increase may occur, could adversely affect both BOK Financial's ability to originate new loans and BOK Financial's ability to grow. Conversely, a decrease in interest rates could result in an acceleration in the payment of loans, including loans underlying BOK Financial's holdings of mortgage-backed securities, and termination of BOK Financial's mortgage servicing rights. In addition, changes in market interest rates, changes in the relationships between short-term and long-term market interest rates or changes in the relationships between different interest rate indices, could affect the interest rates charged on interest-earning assets differently than the interest rates paid on interest-bearing liabilities. This difference could result in an increase in interest expense relative to interest income. BOK Financial's strategy of borrowing funds in the capital markets to supplement deposit growth subjects us to additional interest rate and liquidity risk. An increase in market interest rates also could adversely effect the ability of BOK Financial's floating-rate borrowers to meet their higher payment obligations. If this occurred, it could cause an increase in nonperforming assets and net charge-offs, which could adversely affect BOK Financial's business. BOK Financial's substantial holdings of mortgage-backed securities and mortgage servicing rights could adversely affect BOK Financial's business. BOK Financial has invested a substantial amount of its holdings in mortgage-backed securities, which are investment interests in pools of mortgages. Mortgage-backed securities are highly sensitive to changes in interest rates. BOK Financial mitigates this risk somewhat by investing principally in shorter duration, mortgage products which are less sensitive to changes in interest rates. Nonetheless, a significant decrease in interest rates could lead mortgage holders to refinance the mortgages constituting the pool backing the securities, subjecting BOK Financial to a risk of prepayment and decreased return on investment due to subsequent reinvestment at lower interest rates. In addition, as part of BOK Financial's mortgage banking business, BOK Financial has acquired substantial holdings of mortgage servicing rights. The value of these rights is also very sensitive to changes in interest rates. Falling interest rates tend to increase loan prepayments, which may lead to cancellation of the related servicing rights. BOK Financial's investments and dealings in mortgage-related products increase the risk that falling interest rates could adversely affect BOK Financial's business. BOK Financial attempts to manage this risk by maintaining an active hedging program for its mortgage servicing rights. BOK Financial's hedging program has only been partially successful in recent years. Substantial competition could adversely affect BOK Financial. Banking is a competitive business. BOK Financial competes actively for loan, deposit and other financial services business in Oklahoma, as well as in BOK Financial's other markets. BOK Financial's competitors include a large number of small and large local and national banks, savings and loan associations, credit unions, trust companies, broker-dealers and underwriters, as well as many financial and nonfinancial firms that offer services similar to BOK Financial's. Large national financial institutions have entered the Oklahoma market. These institutions have substantial capital, technology and marketing resources. Such large financial institutions may have greater access to capital at a lower cost than BOK Financial does, which may adversely affect BOK 8 Financial's ability to compete effectively. In addition, there have been a number of recent mergers involving financial institutions located in Oklahoma and BOK Financial's other markets. Significant limitations in Oklahoma on the ability of existing banks to establish branches expired on June 30, 1999. Accordingly, BOK Financial may face increased competition from both merged banks and new entrants to BOK Financial's markets. BOK Financial has expanded into markets outside of Oklahoma, where it competes with a large number of financial institutions that have an established customer base and greater market share than BOK Financial. BOK Financial may not be able to continue to compete successfully in these markets outside of Oklahoma. With respect to some of its services, BOK Financial competes with non-bank companies that are not subject to regulation. The absence of regulatory requirements may give non-banks a competitive advantage. Adverse factors could impact BOK Financial's ability to implement its operating strategy. Although BOK Financial has developed an operating strategy which it expects to result in continuing improved financial performance, BOK Financial cannot assure you that it will be successful in fulfilling this strategy or that this operating strategy will be successful. Achieving success is dependent upon a number of factors, many of which are beyond BOK Financial's direct control. Factors that may adversely affect BOK Financial's ability to implement its operating strategy include: . deterioration of BOK Financial's asset quality; . inability to control BOK Financial's noninterest expenses; . inability to increase noninterest income; . deterioration in general economic conditions, especially in BOK Financial's core markets; . decreases in net interest margins; . increases in competition; and . adverse regulatory developments. Banking regulations or changes in banking regulations could adversely affect BOK Financial. BOK Financial and its subsidiaries are extensively regulated under both federal and state law. In particular, BOK Financial is subject to the Bank Holding Company Act of 1956 and its subsidiary banks are subject to the National Bank Act. These regulations are primarily for the benefit and protection of BOK Financial's customers and not for the benefit of BOK Financial's shareholders. In the past, BOK Financial's business has been materially effected by these regulations. For example, regulations limit BOK Financial's business to banking and related businesses, and they limit the location of BOK Financial's branches and offices, as well as the amount of deposits that it can hold in a particular state. These regulations may limit BOK Financial's ability to grow and expand into new markets and businesses. Additionally, under the Community Reinvestment Act, BOK Financial is required to provide services in traditionally underserved areas. BOK Financial's ability to make acquisitions and engage in new business may be limited by these requirements. In addition, the Federal Deposit Insurance Corporation Improvement Act of 1991 and the Bank Holding Company Act of 1956, and various regulations of regulatory authorities, require us to maintain specified capital ratios. Any failure to maintain required capital ratios would limit the growth potential of BOK Financial's business. Under a long-standing policy of the Board of Governors of the Federal Reserve System, a bank holding company is expected to act as a source of financial strength for its subsidiary banks. As a result of that policy, BOK Financial may be required to commit financial and other resources to its subsidiary banks in circumstances where we might not otherwise do so. 9 The trend toward extensive regulation is likely to continue in the future. Laws, regulations or policies currently affecting us and BOK Financial's subsidiaries may change at any time. Regulatory authorities may also change their interpretation of these statutes and regulations. Therefore, BOK Financial's business may be adversely affected by any future changes in laws, regulations, policies or interpretations. Statutory restrictions on subsidiary dividends and other distributions and debts of BOK Financial's subsidiaries could limit amounts BOK Financial's subsidiaries may pay to BOK Financial. BOK Financial is a bank holding company, and a substantial portion of BOK Financial's cash flow typically comes from dividends that BOK Financial's bank and nonbank subsidiaries pay to BOK Financial. Various statutory provisions restrict the amount of dividends BOK Financial's subsidiaries can pay to BOK Financial without regulatory approval. Management has also developed, and the BOK Financial board of directors approved, an internal capital policy that is more restrictive than the regulatory capital standards. In addition, if any of BOK Financial's subsidiaries liquidates, that subsidiary's creditors will be entitled to receive distributions from the assets of that subsidiary to satisfy their claims against it before BOK Financial, as a holder of an equity interest in the subsidiary, will be entitled to receive any of the assets of the subsidiary. If, however, BOK Financial is a creditor of the subsidiary with recognized claims against it, BOK Financial will be in the same position as other creditors. Although publicly traded, BOK Financial's common stock has substantially less liquidity than the average trading market for a stock quoted on the Nasdaq National Market System. A relatively small fraction of BOK Financial's outstanding common stock is actively traded. The risks of low liquidity include increased volatility of the price of BOK Financial's common stock. Low liquidity may also limit holders of BOK Financial's common stock in their ability to sell or transfer BOK Financial's shares at the price, time and quantity desired. BOK Financial's principal shareholder controls a majority of BOK Financial's common stock. Mr. George B. Kaiser owns a majority of the outstanding shares of BOK Financial common stock. Following the merger, Mr. Kaiser will continue to be able to elect all of BOK Financial's directors and effectively to control the vote on all matters submitted to a vote of BOK Financial's common shareholders. Mr. Kaiser's ability to prevent an unsolicited bid for BOK Financial or any other change in control could have an adverse effect on the market price for BOK Financial's common stock. A substantial majority of BOK Financial's directors are not officers or employees of BOK Financial or any of its affiliates. However, because of Mr. Kaiser's control over the election of BOK Financial's directors, he could change the composition of BOK Financial's Board of Directors so that it would not have a majority of outside directors. Possible future sales of shares by BOK Financial's principal shareholder could adversely affect the market price of BOK Financial's common stock. Mr. Kaiser has the right to sell shares of BOK Financial's common stock in compliance with the federal securities laws at any time, or from time to time. The federal securities laws are the only restrictions on Mr. Kaiser's ability to sell. Because of his current control of BOK Financial, Mr. Kaiser could sell large amounts of his shares of BOK Financial common stock by causing BOK Financial to file a registration statement that would allow him to sell shares more easily. In addition, Mr. Kaiser could sell his shares of BOK Financial common stock without registration under Rule 144 of the Securities Act. Although BOK Financial can make no predictions as to the effect, if any, that such sales would have on the market price of BOK Financial common stock, sales of substantial amounts of BOK Financial common stock, or the perception that such sales could occur, could adversely affect market prices. If Mr. Kaiser sells or transfers his shares of BOK Financial common stock as a block, another person or entity could become BOK Financial controlling shareholder. 10 COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION Shares of BOK Financial common stock are listed on the NASDAQ under the symbol "BOKF".

Bank of Tanglewood has not paid dividends since inception and has no present plans to pay a dividend. In the event the merger is not completed, the declaration and payment of such dividends will be at the discretion of the board of directors of Bank of Tanglewood and will depend upon future earnings of Bank of Tanglewood, its general financial condition, the success of its business activities, its capital requirements and general business conditions. 11 SUMMARY SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA Selected Historical Consolidated Financial Data of BOK Financial BOK Financial is providing the following information to aid you in your analysis of the financial aspects of the merger. BOK Financial derived the information as of and for the years ended December 31, 1997 through December 31, 2001 from its historical audited consolidated financial statements for those fiscal years. BOK Financial derived the financial information for the six months ended June 30, 2002 and 2001 from its unaudited financial statements. The audited and unaudited financial information contained in this proxy statement-prospectus is the same historical information that BOK Financial has presented in its prior filings with the SEC, except as noted. The operating results for the six months ended June 30, 2002 are not necessarily indicative of the operating results that may be expected for the year ended December 31, 2002. BOK Financial expects that it will incur merger and restructuring expenses as a result of the acquisition of Bank of Tanglewood. BOK Financial and Bank of Tanglewood both anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses and enhanced opportunities to earn more revenue. The historical information presented below does not reflect these financial expenses or benefits and, accordingly, does not attempt to predict or suggest future results.

Selected Historical Consolidated Financial Data of Bank of Tanglewood The following table summarizes financial results achieved by Bank of Tanglewood for the periods and at the dates indicated and should be read in conjunction with Bank of Tanglewood's financial statements and the notes to the financial statements. The selected financial data as of December 31, 2001 and 2000 and for each of the years in the two-year period ended December 31, 2001 are derived from Bank of Tanglewood's audited financial statements and related notes included elsewhere in this proxy statement-prospectus. The selected financial data as of December 31, 1999, 1998 and 1997 and for each of the years in the three-year period ended December 31, 1999 is derived from Bank of Tanglewood's audited financial statements and related notes which are not included in this proxy statement-prospectus. Financial amounts as of and for the six months ended June 30, 2002 and June 30, 2001 are unaudited, but management of Bank of Tanglewood believes that such amounts reflect all normal recurring adjustments necessary for a fair presentation of the results of operations and financial position for those periods. You should not assume the results of operations for past periods and for the six months ended June 30, 2002 indicate results for any future period. 13 As of and for the Six Months Ended June 30, As of and for the Year Ended December 31, ---------------------- -------------------------------------------------- 2002 2001 2001 2000 1999 1998 1997(1) ---------- ---------- ---------- -------- -------- -------- -------- (Dollars in thousands, except per share data) Income Statement Data: Net interest income........................ $ 5,215 $ 3,502 $ 8,047 $ 5,302 $ 3,605 $ 2,508 $ 1,409 Provision for loan losses.................. 155 75 272 316 445 90 90 ---------- ---------- ---------- -------- -------- -------- -------- Net interest income after provision for loan losses........................ 5,060 3,427 7,775 4,986 3,160 2,418 1,319 Noninterest income......................... 483 544 1,028 364 176 170 77 Noninterest expense........................ 3,150 2,631 5,858 3,867 2,785 2,068 1,439 ---------- ---------- ---------- -------- -------- -------- -------- Income before taxes..................... 2,393 1,340 2,945 1,483 551 520 (43) Provision for income taxes................. 762 436 921 409 144 138 -- ---------- ---------- ---------- -------- -------- -------- -------- Net income (loss)....................... $ 1,631 $ 904 $ 2,024 $ 1,074 $ 407 $ 382 $ (43) ========== ========== ========== ======== ======== ======== ======== Per Share Data: Basic earnings (loss) per share............ $ 1.67 $ 0.95 $ 2.10 $ 1.19 $ 0.46 $ 0.58 $ (0.07) Diluted earnings (loss) per share.......... 1.49 0.86 1.89 1.08 0.42 0.52 (0.06) Book value per share....................... 17.58 15.14 16.04 13.22 11.60 11.03 9.79 Cash dividends declared.................... -- -- -- -- -- -- -- Weighted average shares outstanding (basic)................................... 977,273 949,264 963,212 900,933 876,294 658,647 650,000 Weighted average shares outstanding (diluted)................................. 1,092,098 1,049,464 1,070,082 991,363 960,074 735,347 703,000 Shares outstanding at end of period........ 977,310 977,160 977,160 901,200 900,800 753,762 650,000 Balance Sheet Data (at period end): Total assets............................... $ 234,256 $ 199,567 $ 250,204 $155,472 $122,086 $ 85,016 $ 66,291 Loans...................................... 134,010 99,247 118,989 82,207 63,177 38,002 24,785 Allowance for loan losses.................. 1,363 1,017 1,215 943 632 187 97 Total deposits............................. 204,740 180,456 221,957 139,050 104,863 75,583 58,888 Borrowings and notes payable............... 11,678 3,649 11,891 3,800 6,388 895 845 Total shareholders' equity................. 17,181 14,792 15,672 11,913 10,453 8,311 6,360 Selected Ratios and Other Data: Return on average assets (2)............... 1.37% 1.04% 1.00% 0.79% 0.62% 0.65% (0.10)% Return on average equity (2)............... 20.04 13.47 14.10 9.80 6.30 7.46 (0.68) Net interest margin (2).................... 4.65 4.24 4.22 4.14 3.75 3.52 3.42 Asset Quality Ratios (3): Nonperforming assets to total loans and other real estate......................... 0.70% 1.21% 0.68% N/A N/A N/A N/A Net loan charge-offs (recoveries) to average loans (2)......................... 0.01 0.001 N/A 0.01 N/A N/A N/A Allowance for loan losses to total loans..................................... 1.02 1.02 1.02 1.15 1.00 0.49 0.39 Allowance for loan losses to nonperforming loans (4)...................

The pro forma data was derived by combining the historical consolidated financial information of BOK Financial and Bank of Tanglewood using the purchase method of accounting for business combinations. In July 2001, the Financial Accounting Standards Board issued Statement No. 142, "Goodwill and Other Intangible Assets," which eliminates the requirement to amortize goodwill and requires goodwill to be evaluated annually, or more frequently if impairment indicators arise, for impairment. The historical and pro forma per share financial information as of and for the year ended December 31, 2001 includes the impact of amortizing goodwill since Statement No. 142 was not effective for the year ended December 31, 2001. The Bank of Tanglewood pro forma equivalent share information shows the effect of the merger from the perspective of an owner of Bank of Tanglewood common stock. The information was computed by multiplying the pro forma information based on an assumed conversion ratio of 1.72, which includes 22,838 shares of BOK Financial common stock to be deposited in the escrow account. You should read the information below together with the historical financial statements and related notes and other information of Bank of Tanglewood included in this proxy statement-prospectus and the historical financial statements and related notes that BOK Financial has presented in its prior Securities and Exchange Commission filings. We have incorporated the information related to BOK Financial into this document by reference. See "Where You Can Find More Information" on page 88 for instructions on how to receive copies of the incorporated information. We expect that Bank of Tanglewood and BOK Financial will incur merger and integration charges and receive certain benefits as a result of combining their companies. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect these expenses or benefits. The unaudited pro forma combined data below is for illustrative purposes only. The companies may have performed differently had they always been combined. You should not rely on this information as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that the combined company will experience after the merger.

This representation is not applicable to the calculation of the regulatory capital of the subsidiary banks of BOK Financial or to the calculation of shareholders' equity for financial reporting purposes or in accordance with generally accepted accounting principles. The "BOK Financial" and "Tanglewood" columns of the following table present the shareholders' equity of BOK Financial and Bank of Tanglewood to regulatory capital prior to consummation of the acquisition. The "Pro Forma Combined" column of the following table reconciles on a pro forma basis the shareholders' equity of BOK Financial combined with Bank of Tanglewood giving effect to the foregoing representation.

Forward-looking statements are based on management's beliefs, assumptions, current expectations, estimates and projections about BOK Financial, the financial services industry and the economy in general. Words such as "anticipates", "believes", "estimates", "expects", "forecasts", "plans", "projects", variations of such words and similar expressions are intended to identify such forward-looking statements. Management judgments relating to, and discussion of the provision and reserve for, loan losses involve judgments as to future events and are inherently forward-looking statements. Assessments that BOK Financial's acquisitions and other growth endeavors will be profitable are necessarily statements of belief as to the outcome of future events, based in part on information provided by others which BOK Financial has not independently verified. Forward-looking statements are not guarantees of future performance and involve risks, uncertainties, and assumptions that are difficult to predict with regard to timing, extent, likelihood, and degree of occurrence. Therefore, actual results and outcomes may materially differ from what is expressed, implied, or forecasted in such forward-looking statements. Many possible events or factors could effect the future financial results and performance of each of our companies before the merger or BOK Financial after the merger and could cause those results or performance to differ materially from those expressed in our forward-looking statements, including, but not limited to: . the ability to fully realize expected cost savings from the merger within the expected time frame, . our ability to integrate our businesses, . general business and economic conditions in the markets we serve, . the ability of other companies on which BOK Financial relies to provide goods and services in a timely and accurate manner, . changes in interest rates and interest rate relationships, . demand for products and services, . the degree of competition by traditional and nontraditional competitors, . changes in banking regulations, tax laws, prices, levies, and assessments, . the impact of technological advances, and . trends in customer behavior as well as their ability to repay loans. We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this proxy statement-prospectus, and we undertake no obligation to update this information unless the securities laws require us to do this. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements in this proxy statement-prospectus and the documents BOK Financial has incorporated by reference. 17 BANK OF TANGLEWOOD SPECIAL MEETING Information about the Shareholder Meeting and Proposals The Bank of Tanglewood board of directors is using this document to solicit proxies from you for use at the special meeting. At the special meeting, shareholders will vote on . a proposal to approve the merger agreement and the transactions contemplated by the merger agreement; . a proposal to approve the executive payments in the amount of $277,805 under existing compensation arrangements between Bank of Tanglewood and Robert G. Greer, Richard W. Jochetz and James L. Tidwell; and . any other matter which may properly come before the special meeting or any adjournment or postponement of the special meeting. Date, Time and Place of the Special Meeting The Bank of Tanglewood special shareholder meeting will be held October 24, 2002 at 10:00 a.m., central standard time, at the Houston Country Club located at One Potomac Drive, Houston, Texas. Record Date for the Special Meeting You may vote at the shareholders meeting if you owned shares of Bank of Tanglewood common stock at the close of business on September 20, 2002. On the record date, 977,470 shares of Bank of Tanglewood common stock were outstanding. Shares Entitled to Vote at the Special Meeting For each share of Bank of Tanglewood common stock that you own on the record date, you will have one vote on each proposal to be presented at the meeting. Quorum Requirement for the Special Meeting The presence at the meeting, in person or by proxy, of the holders of a majority of the outstanding shares of Bank of Tanglewood common stock is necessary to constitute a quorum. If a quorum is not represented at the meeting, the meeting will be adjourned to a subsequent date. Abstentions and broker non-votes count as present for establishing a quorum. Shares Owned by Bank of Tanglewood Directors and Executive Officers as of Record Date As of September 20, 2002, the executive officers and directors of Bank of Tanglewood owned or otherwise controlled 160,531 shares of Bank of Tanglewood common stock, which does not include any options outstanding to acquire shares of Bank of Tanglewood common stock. These shares represent approximately 16.42% of the shares of Bank of Tanglewood common stock outstanding as of the record date. These individuals, although not bound by an agreement, have indicated that they intend to vote their shares of Bank of Tanglewood common stock in favor of the approval of the merger agreement and the merger and the executive payments to Messrs. Greer, Jochetz and Tidwell. Messrs. Greer, Jochetz and Tidwell (and certain of their family members) will abstain from voting with respect to the executive payments as required by the Internal Revenue Code and their shares will not be counted as outstanding for purposes of voting on that matter. 18 Votes Necessary at the Meeting to Approve Bank of Tanglewood Proposals Approval of the merger agreement and the transactions contemplated by the merger agreement requires the approval of the holders of two-thirds of the outstanding shares of Bank of Tanglewood common stock entitled to vote on the merger. Approval of the executive payments in the aggregate amount of $277,805 which have been waived by Messrs. Robert G. Greer, Richard W. Jochetz and James L. Tidwell requires the approval of the holders of 75% of the outstanding shares of Bank of Tanglewood common stock entitled to vote on the proposal. The shares of Bank of Tanglewood common stock held by Messrs. Greer, Jochetz and Tidwell (and certain of their family members) will not be entitled to vote on this matter and will not be counted as shares outstanding for purposes of this matter. The proposals to approve the merger agreement and the executive payments are "non-discretionary" items, meaning that brokers and banks who hold shares in an account for customers who are the beneficial owners of such shares may not give a proxy to vote those shares without specific instructions from their customers. Any abstentions and broker non-votes will have the same effect as votes against approval of the merger agreement and the executive payments. Accordingly, the Bank of Tanglewood board of directors encourages you to complete, date and sign the accompanying proxy and return it promptly in the enclosed postage-paid envelope. Voting and Revocation of Proxies You may vote in person at the special meeting or by proxy. We recommend you vote by proxy even if you plan to attend the meeting. To vote by proxy, you should complete, sign and date the enclosed proxy and return it to Bank of Tanglewood in the enclosed postage prepaid envelope. You can revoke your proxy before it is voted as described below. If you are the record holder or your shares, you may revoke your proxy before it is voted by: . submitting a new proxy with a later date, . notifying Bank of Tanglewood's Secretary, in writing, before the special meeting that you have revoked your proxy; or . voting in person, or notifying the Secretary orally of your wish to revoke your proxy, at the shareholder meeting. If you hold your shares in street name with a bank or broker, you must contact the bank or broker if you wish to revoke your proxy. All written notices of revocation and other communications with respect to revocation or proxies should be sent to: Bank of Tanglewood, N.A., 500 Chimney Rock Road, Houston, Texas 77056, Attention: James Tidwell, Secretary. Other Voting Matters Voting in Person. If you plan to attend the meeting and wish to vote in person, we will give you a ballot at the special meeting. However, if your shares of common stock are held in the name of a brokerage firm or trustee, you must obtain from the firm or trustee an account statement, letter or other evidence of your beneficial ownership of the common shares in order for you to vote in person at the meeting. People with Disabilities. We can provide reasonable assistance to help you participate in the shareholder meeting if you tell us about your disability and your plan to attend. Please call or write the Secretary of Bank of Tanglewood at least two weeks before the shareholder meeting at the number or address provided on page 1 of this proxy statement-prospectus. 19 Proxy Solicitation; Expenses. We will each pay our own costs of soliciting proxies, including the reasonable expenses of brokers, banks, fiduciaries and other nominees in forwarding solicitation material to beneficial owners. In addition to the solicitation of proxies by use of the mail, solicitation may be made by telephone and facsimile and Bank of Tanglewood may utilize the services of some of its officers and employees to solicit proxies personally. Such officers and employees will not be additionally compensated for such solicitation, but may be reimbursed for out-of-pocket expenses incurred in connection therewith. If undertaken, we expect the expense of such solicitation by officers and employees to be nominal. Bank of Tanglewood will file with the SEC all materials used to aid in the solicitation of proxies. Do not send any Bank of Tanglewood stock certificates with your proxy. If the merger is consummated, the exchange agent will mail transmittal forms with instructions for the surrender of stock certificates promptly after completion of the merger. Other Business; Adjournments and Postponements We currently are not aware of any other business to be acted upon at the meeting. If, however, other matters are properly brought before the meeting, or any adjourned or postponed meeting, your proxies will have discretion to vote or act on those matters according to their best judgment, including to adjourn the meeting. Adjournments or postponements of the shareholder meeting may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time by approval of the holders of Bank of Tanglewood common stock representing a majority of the votes present in person or by proxy at the meeting, whether or not a quorum exists, without further notice other than by an announcement made at the special meeting. A vote by proxy against the merger will result in such proxy being voted against an adjournment or postponement of the shareholder meeting to solicit additional proxies. A vote by proxy in favor of the merger will result in such proxy being voted for an adjournment or postponement of a shareholder meeting to solicit additional proxies. 20 PROPOSAL I--APPROVAL OF THE MERGER AGREEMENT AND THE MERGER Background of the Merger In early February 2002, Bank of Tanglewood's Chief Financial Officer and one of BOK Financial's mergers and acquisitions representatives met at a mergers and acquisitions conference. While they did not discuss the concept of a merger, they agreed that BOK Financial representatives would contact Bank of Tanglewood's management team in the near future. In late February, BOK Financial representatives met with Bank of Tanglewood's Chairman, Chief Executive Officer and Chief Financial Officer. At that time, Bank of Tanglewood's management team indicated that they were not actively pursuing sales opportunities, although they would not rule out a sale in the event the correct suitor presented an acceptable offer. In March 2002, Bank of Tanglewood received an unsolicited offer to be acquired by another Texas-based financial institution. The Bank of Tanglewood board of directors determined that it was in the shareholders' best interest to consider a sale and to determine if others in the marketplace might be interested in acquiring Bank of Tanglewood. Bank of Tanglewood then engaged Hovde Financial, LLC on March 21, 2002 to, among other things, assist in exploring ways to enhance shareholder value, including studying Bank of Tanglewood's acquisition value and identifying potential acquirers. The board authorized Hovde to contact a limited number of qualified prospects to determine their interest in a business combination with Bank of Tanglewood. In March 2002, Hovde contacted seven potential acquirers, including BOK Financial, to determine their level of interest in the possible acquisition of Bank of Tanglewood. Four financial institutions expressed interest in Bank of Tanglewood. In March 2002, Hovde initially contacted BOK Financial inviting BOK Financial's participation in the purchase process. BOK Financial also received and signed an agreement to keep confidential any nonpublic information concerning Bank of Tanglewood that BOK Financial may obtain during such process. During March, BOK Financial evaluated the financial information relating to Bank of Tanglewood supplied by Hovde. On March 28, 2002, BOK Financial hand delivered to Bank of Tanglewood a preliminary, nonbinding letter expressing its interest in acquiring Bank of Tanglewood. After discussions with Bank of Tanglewood's management, BOK Financial issued a revised nonbinding letter to Bank of Tanglewood on April 12, 2002. The indication of interest from BOK Financial offered consideration that the Board deemed superior to the other offer seriously being considered by Bank of Tanglewood. On April 12, 2002, the board of directors authorized Bank of Tanglewood management to invite BOK Financial to perform due diligence and, upon its completion, to enter into negotiations of a definitive agreement. BOK Financial performed due diligence in late April 2002 and the parties began the negotiation of a definitive agreement. At a meeting of the Bank of Tanglewood board of directors on May 9, 2002, a representative of Hovde informed the board of directors orally that, in Hovde's opinion: (1) an acquisition of Bank of Tanglewood in the present time frame at the price levels indicated in the written indications of interest would be in the best economic interests of Bank of Tanglewood and its shareholders; (2) based on numerous factors, including the current price levels at which bank acquisition transactions of comparable size in Texas and the southwest were currently being effected, the price proposed in the BOK Financial offer was more favorable than the other offers; and (3) the merger consideration offered by BOK Financial was fair to Bank of Tanglewood and its shareholders from a financial point of view. As a result, the board of directors determined that the price being offered by BOK Financial, along with the other terms of BOK Financial's offer, made it the more advantageous offer. At the special meeting on May 9, 2002, subject to finalization of certain provisions of the definitive agreement and execution of employment agreements and option amendment agreements, the Bank of Tanglewood board of directors approved the merger and related transactions. At its regular meeting on May 15, 2002, the board of directors approved the final terms of the definitive agreement and it was executed the same day. 21 Bank of Tanglewood Reasons for the Merger The terms of the merger agreement, including the consideration to be paid to Bank of Tanglewood shareholders, were the result of arm's length negotiations between representatives of BOK Financial and Bank of Tanglewood. In evaluating whether to affiliate with BOK Financial, the Bank of Tanglewood board considered a number of factors, including, without limitation, the following: . the additional capital and resources needed for Bank of Tanglewood's operations to continue to grow and the dilutive effect to shareholders of obtaining this additional capital; . information regarding the financial condition, business, operating results, earnings, financial condition, technological capabilities, management, earnings and prospects of each of Bank of Tanglewood and BOK Financial; . the merger consideration in the form of BOK Financial common stock with a closing price on May 15, 2002 of $35.82 per share, or an aggregate of approximately $65.0 million less transaction costs, compared with the Bank of Tanglewood shareholders' equity and earnings as of March 31, 2002; . the current financial services industry environment, including the continued consolidation within the industry, the increased competition in the market areas served by Bank of Tanglewood and the costs of evolving trends in technology; . the appreciation in the price of BOK Financial common stock and the prospects for positive long-term performance of BOK Financial common stock; . the belief of Bank of Tanglewood's board that the terms of the merger and the merger agreement are fair to and in the best interests of Bank of Tanglewood shareholders; . the analyses provided by Hovde and the oral and written preliminary opinion of Hovde provided on May 9, 2002 that, as of such date, the conversion ratio as set out in the merger agreement was fair from a financial point of view to Bank of Tanglewood shareholders (see "Opinion of Bank of Tanglewood's Financial Advisor" beginning on page 29); . the tax-free nature of the exchange of BOK Financial common stock as the merger consideration to Bank of Tanglewood shareholders for federal income tax purposes; . the fact that BOK Financial common stock is publicly traded on the NASDAQ, thereby representing a more liquid investment than Bank of Tanglewood common stock, which is closely held with little trading activity or liquidity; . the historical stock dividends paid by BOK Financial on its common stock as compared with the fact that Bank of Tanglewood has never paid a dividend on its common stock; . the board's review of other strategic alternatives potentially available to Bank of Tanglewood; . BOK Financial's ability to provide the ever-increasing and broadening array of financial services and products demanded by Bank of Tanglewood's customers; and . the financial terms of other recent business combinations in the banking industry. Bank of Tanglewood's board of directors determined that Bank of Tanglewood's competitive position and the value of its stock could best be enhanced through affiliation with BOK Financial. The aggregate price to be paid to holders of Bank of Tanglewood common stock resulted from negotiations which considered the historical earnings and dividends of BOK Financial and Bank of Tanglewood; the potential growth in Bank of Tanglewood's market and earnings, both as an independent entity and as a part of a larger organization such as BOK Financial; Bank of Tanglewood's asset quality; and the effect of the merger on the shareholders, customers and employees of Bank of Tanglewood and the communities that Bank of Tanglewood serves. 22 The above discussion of the information and factors considered by the Bank of Tanglewood board is not intended to be exhaustive, but includes the material factors the Bank of Tanglewood board considered. In reaching its determination to approve and recommend the merger, the Bank of Tanglewood board did not assign any relative or specific weights to the foregoing factors, and individual directors may have given differing weights to different factors. Recommendation of the Bank of Tanglewood Board of Directors The Bank of Tanglewood board of directors believes that the merger is in the best interests of Bank of Tanglewood and its shareholders. Accordingly, the Bank of Tanglewood board has unanimously approved the merger agreement and unanimously recommends that you vote FOR approval of the merger agreement and the transactions contemplated by the merger agreement. BOK Financial Reasons for the Merger In approving the merger agreement and the transactions contemplated by the merger agreement, including the merger, the BOK Financial board of directors considered a number of factors, including the following: . BOK Financial's Growth Strategy. The BOK Financial board of directors considered that BOK Financial has found that it is more efficient to develop emerging markets through carefully chosen acquisitions than by establishing de novo operations. The board of directors felt that the acquisition of Bank of Tanglewood complemented the current operations of its subsidiary, Bank of Texas, N.A., in the Houston area. . Enhanced Service; Benefits to Customers. The BOK Financial board of directors considered the fact that the acquisition of Bank of Tanglewood and its three locations will enhance service for Bank of Texas's customers in the Houston area and that it will allow Bank of Tanglewood to expand its current customer base into market niches previously unavailable to Bank of Tanglewood. . Terms of the Transaction. The BOK Financial board of directors considered the terms of the transaction as contemplated by the merger agreement, including the representations and warranties, covenants, termination provisions and conditions to the merger and found them acceptable. . Financial Considerations. The BOK Financial board of directors considered certain financial issues, including information relating to the financial condition, results of operations, earnings and businesses of Bank of Tanglewood, on both a historical and prospective basis. . Bank of Tanglewood Management Team. The BOK Financial board of directors considered the quality and experience of the members of Bank of Tanglewood's existing management team, and the terms and conditions upon which such persons have generally agreed to remain employed by the surviving association following the merger. . Reputation of Bank of Tanglewood. The BOK Financial board of directors considered the reputation of Bank of Tanglewood for quality customer service. . Risk Factors. The BOK Financial board of directors considered certain of the matters set forth in this proxy statement-prospectus under the heading "Risk Factors". The foregoing discussion of the information and factors considered by the BOK Financial board of directors is not intended to be exhaustive, but includes the material factors considered by the BOK Financial board of directors. In view of the variety of factors considered in connection with its evaluation of the merger, the BOK Financial board of directors did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given differing weights to different factors. 23 Accounting Treatment Under generally accepted accounting principles, the merger will be accounted for as a purchase. Under this accounting method, BOK Financial will record Bank of Tanglewood's assets and liabilities at their fair values, including any identifiable intangible assets. If the purchase price exceeds the net fair value of assets acquired, BOK Financial will record the excess as goodwill, which is not amortized. Instead, goodwill is evaluated annually, or more frequently if impairment indicators arise, for impairment. BOK Financial will include the revenues and expenses of Bank of Tanglewood in BOK Financial's financial statements from the date of the consummation of the merger. Regulatory Approvals The parties, being subject to the Bank Holding Company Act of 1956 and the National Bank Act, are required to receive approval for the merger of Bank of Tanglewood into TW Interim from the Office of the Comptroller of the Currency, the Federal Reserve Board and the Texas Department of Banking. Pursuant to the merger agreement, it is a condition of completion of the merger that the OCC and the FRB also approve a subsequent merger of the merged Tanglewood/TW Interim entity into Bank of Texas, N.A., a wholly owned subsidiary of BOK Financial. BOK Financial filed applications with the FRB, the OCC and the TDB to obtain approval of the mergers and has subsequently obtained approval from all three entities and all applicable waiting periods have expired. The approval of any application merely implies satisfaction of regulatory criteria for approval, which does not include review of the merger from the standpoint of the adequacy of the consideration to be received by, or fairness to, shareholders. Regulatory approvals do not constitute an endorsement or recommendation of the proposed merger. BOK Financial and Bank of Tanglewood are not aware of any governmental approvals or compliance with banking laws and regulations that are required for the merger to become effective other than those described above. Material U.S. Federal Income Tax Consequences The following discussion describes the material United States federal income tax consequences of the exchange of Bank of Tanglewood common stock for BOK Financial common stock pursuant to the merger. This discussion is based on the Internal Revenue Code of 1986, as amended, related regulations, existing administrative interpretations and court decisions, all of which are subject to change, possibly with retroactive effect. This discussion assumes you hold your common stock of Bank of Tanglewood as a capital asset within the meaning of Section 1221 of the Internal Revenue Code. This discussion does not address all aspects of United States federal income taxation that may be important to you in light of your particular circumstances or if you are subject to special rules, such as rules relating to: . financial institutions; . regulated investment companies; . pass through entities; . mutual funds; . tax-exempt organizations; . insurance companies; . dealers in securities or foreign currencies; . traders in securities who elect to apply a mark-to-market method of accounting; . foreign holders; 24 . persons who hold shares of Bank of Tanglewood common stock as a hedge against currency risk or as part of a straddle, constructive sale or conversion transaction; or . holders who acquired their shares of Bank of Tanglewood common stock upon the exercise of warrants or employee stock options or otherwise as compensation. Completion of the merger is conditioned on the delivery of an opinion to Bank of Tanglewood from Bracewell & Patterson, L.L.P., stating that, on the basis of the facts, representations and assumptions set forth in the opinion, and based on certain representations as to the factual matters to be executed by appropriate officers of Bank of Tanglewood and BOK Financial, the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code. This opinion neither binds the Internal Revenue Service or precludes the Internal Revenue Service from adopting a position contrary to that expressed in the opinion, and no assurance can be given that contrary positions will not be successfully asserted by the Internal Revenue Service nor adopted by a court if the issues are litigated. Neither Bank of Tanglewood or BOK Financial intends to obtain a ruling from the Internal Revenue Service with respect to the tax consequences of the merger or the ownership and disposition of benchmark price protection rights. Tax Consequences of the Merger. Bracewell & Patterson, L.L.P. has rendered its opinion subject to the above limitations and on the basis of facts, representations and assumptions set forth or referred to in the opinion, which are consistent with the state of facts existing at the effective time of the merger, that for federal income tax purposes: . the merger will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code and Bank of Tanglewood, BOK Financial and TW Interim will each be a party to the reorganization; . you will recognize gain, but not loss for United States federal income tax purposes when you exchange your Bank of Tanglewood common stock for BOK Financial common stock and the benchmark price protection pursuant to the merger; . the amount of gain that you must recognize as a result of the merger, and on which you will pay taxes, will equal the lesser of the following: (i) the fair market value of the benchmark price protection that you receive in the exchange and (ii) the amount of gain you actually realize in the exchange. The amount of gain you realize in the exchange will equal: (i) the fair market value of the benchmark price protection plus the fair market value of the BOK Financial common stock that you receive in the merger minus (ii) your adjusted tax basis in the Bank of Tanglewood common stock that you surrendered in the merger; . any gain you recognize will constitute long term capital gain if your holding period in your Bank of Tanglewood common stock exceeds one year at the time of the exchange; . your aggregate tax basis in the BOK Financial common stock you receive as a result of the merger will be the same as your aggregate adjusted tax basis in the Bank of Tanglewood common stock you surrender in the exchange, increased by any gain you recognize because of the merger; . the holding period of the BOK Financial common stock you receive as a result of the exchange, but not including the BOK Financial stock you might receive because of the benchmark price protection, will include the period during which you held the Bank of Tanglewood common stock you exchange in the merger; . neither BOK Financial, Bank of Tanglewood nor TW Interim National Bank will recognize gain or loss for federal income tax purposes as a result of the merger. Fractional shares of BOK Financial common stock will not be issued in the merger. Any fractional share will be rounded up to a whole share. 25 Back-up Withholding. Unless an exemption applies under the applicable law and regulations, the exchange agent must withhold 31% of any cash payments you are entitled to in the merger. The exchange agent will not withhold this amount if you provide your tax identification number, social security or employer identification number and certify that the number is correct. You must complete and sign the substitute Form W-9 that will be included as part of the transmittal letter sent by the exchange agent to avoid back-up withholding, unless an applicable exemption exists and is proved in a manner satisfactory to the exchange agent. Tax Consequences of Ownership and Disposition of Benchmark Price Protection Rights. The federal income tax consequences to you from the payment at or before maturity, lapse or disposition of any benchmark price protection that you receive in the merger will depend upon how the Internal Revenue Service characterizes the benchmark price protection for federal income tax purposes. The Internal Revenue Service has taken the position that taxpayers should treat rights similar to the benchmark price protection as "cash settlement put options" for federal income tax purposes. However, it is possible that the benchmark price protection might be treated as debt instruments or in some other manner. Legislation, regulations, court decisions and revenue rulings after the merger but prior to payment, lapse or disposition of the benchmark price protection could affect the federal income tax treatment of the benchmark price protection. BOK Financial anticipates that it will treat the benchmark price protection as cash settlement put options for federal income tax purposes, and the following summary assumes that the Internal Revenue Service will treat the benchmark price protection as cash settlement put options for federal income tax purposes, except as specifically noted. For details regarding the valuation and terms of the benchmark price protection see "Benchmark Price Protection" on pages 40 and 41. Unless the straddle rules as described below apply, upon the payment at or before maturity or sale or exchange of the benchmark price protection, generally you will recognize capital gain or loss in an amount equal to the difference between the cash or fair market value of the BOK Financial common stock paid in respect of the benchmark price protection and your tax basis in the benchmark price protection. Your tax basis in the benchmark price protection generally should equal the fair market value of the benchmark price protection at the time the merger is completed. In the event your benchmark price protection lapse without any payment to you, you will recognize capital loss equal to your tax basis in your benchmark price protection. Your capital gain or loss will be long term if your holding period in the benchmark price protection is more than one year at the time of payment, lapse, sale or exchange. If you hold both benchmark price protection and BOK Financial common stock at the time of a payment, lapse or disposition of benchmark price protection, the tax rules dealing with "straddles" may apply to you. A straddle is, in general terms, offsetting positions in personal property, such as a long and short position in the same stock. The applicability of the straddle rules to these circumstances is not clear under current tax law. In the event, however, that the Internal Revenue Service determines that your benchmark price protection and your BOK Financial common stock comprise a straddle: . some or all of the capital loss that you would otherwise recognize on your BOK Financial common stock may be deferred until a later tax year. The amount deferred would be equal to the amount by which the fair market value of the BOK Financial common stock and benchmark price protection you own exceeds your adjusted tax basis in the BOK Financial common stock and the benchmark price protection on the last trading day of the tax year in which you would otherwise recognize the capital loss. The deferred portion of such loss would be treated as loss incurred in a later taxable year, the recognition of which would continue to be subject to the straddle rules; . if you had a holding period in your BOK Financial common stock of more than one year when you received your benchmark price protection, some or all of the capital loss that you would otherwise recognize on the disposition of your BOK Financial common stock may be deferred, and some or all of the capital gain that you would recognize on the disposition of your BOK Financial common stock may be characterized as short term capital gain instead of long term capital gain, but any capital loss recognized by you on your benchmark price protection will be long term, regardless of your holding period in the benchmark price protection; 26 . if you had a holding period in your BOK Financial common stock of one year or less when you received your benchmark price protection, some or all of the capital gain or loss that you would otherwise recognize upon a payment at or before maturity, lapse, sale or exchange of the benchmark price protection may be short term capital gain or loss instead of long term capital gain or loss; . if you had a holding period of one year or less in your BOK Financial common stock when you received your benchmark price protection , some or all of the capital loss that you would otherwise recognize on a disposition of your BOK Financial common stock shares may be deferred and be short term capital loss instead of long term capital loss; . you may not be able to deduct interest and carrying charges allocable to the benchmark price protection or your BOK Financial common stock. Such items will increase your adjusted tax basis in benchmark price protection and BOK Financial common stock, respectively; . since the treatment of contemporaneous ownership of benchmark price protection and BOK Financial common stock as a straddle is not clear, you should consult your own tax advisor at the time of payment, lapse or disposition of the benchmark price protection. This discussion is not intended to be a complete analysis or description of all potential United States federal income tax consequences or any other consequences of the merger. In addition, this discussion does not address tax consequences which may vary with, or be contingent on, your individual circumstances. Moreover, this discussion does not address any non-income tax or any foreign, state or local tax consequences of the merger. Accordingly, you are strongly urged to consult with your own tax advisor to determine the particular United States federal, state, local or foreign income or other tax consequences to you of the merger. Dissenters' Rights of Appraisal Holders of shares of Bank of Tanglewood common stock have a statutory right to dissent from the merger by following the specific procedures set forth below. If the merger is approved and consummated, holders of shares of Bank of Tanglewood common stock who properly perfect their dissenters' rights will be entitled to receive an amount of cash equal to the fair value of their shares of Bank of Tanglewood common stock rather than being required to accept the consideration provided in the merger agreement. The following summary is not a complete statement of the statutory dissenters' rights of appraisal, and such summary is qualified in its entirety by reference to the applicable provisions of the National Bank Act, which are reproduced in full at Annex IX to this proxy statement-prospectus. A Bank of Tanglewood shareholder must follow the exact procedure required by the National Bank Act in order to properly exercise his or her dissenter's rights of appraisal and avoid waiver of those rights. If the merger is approved at the Bank of Tanglewood special meeting, any Bank of Tanglewood shareholder who has voted against the merger at the special meeting or who has given notice in writing at or prior to the special meeting to the presiding officer that he or she dissents from the merger agreement will be entitled to receive the value of the shares of Bank of Tanglewood held by him or her when the merger is approved by the OCC by making a written request to the receiving association at any time before thirty days after the date of consummation of the merger. At the time the Bank of Tanglewood shareholder makes the written request, he or she must also surrender his or her certificates representing the Bank of Tanglewood common stock. If the Bank of Tanglewood and the dissenting shareholder are not able to agree on the fair value of his or her stock, the value of the Bank of Tanglewood common stock owned by any dissenting shareholders shall be ascertained, as of the effective date of the merger, by an appraisal made by a committee of three people, composed of (1) one selected by the vote of the holders of the majority of the Bank of Tanglewood common stock for which the owners request appraisal; (2) one selected by the directors of the receiving association and (3) one selected by the two so selected. The valuation of the Bank of Tanglewood common stock agreed upon by any two of the three appraisers shall govern. 27 If the value so fixed is not satisfactory to any dissenting shareholder who has requested payment for his or her Bank of Tanglewood common stock, that shareholder may, within five days after being notified of the appraised value of his or her shares, appeal to the OCC. The OCC shall cause a reappraisal to be made which shall be final and binding as to the value of the shares. If within ninety days from the date of consummation of the merger, for any reason one or more of the appraisers is not selected, or the appraisers fail to determine the value of the Bank of Tanglewood common stock, the OCC, upon written request of any interested party, shall cause an appraisal to be made which shall be final and binding on all parties. The expenses of the OCC in making the reappraisal or the appraisal, as the case may be, shall be paid by the receiving association. The value of the Bank of Tanglewood common stock ascertained shall be promptly paid to the dissenting shareholders. The shares of Bank of Tanglewood common stock that would have been delivered to dissenting shareholders had they not requested payment shall be sold, and if the shares are sold at a price greater than the amount paid to the dissenting shareholders, the excess in the sale price shall be paid to the dissenting shareholders. Any shareholder who votes against the merger at the special meeting, or who gives notice in writing at or prior to the special meeting to the presiding officer of the meeting, that he or she dissents from the merger, will be notified in writing of the date of consummation of the merger. The OCC issued Banking Circular 259 which describes the methods used by the OCC to estimate the value of a bank's shares when a shareholder dissents from a conversion, merger or consolidation involving a national bank. The following summary is not a complete statement of Banking Circular 259, and such summary is qualified in its entirety by reference to the applicable provisions of Banking Circular 259, which is reproduced in full at Annex IX to this proxy statement-prospectus. Through its appraisal process, the OCC attempts to arrive at a fair estimate of the value of a bank's stock. The OCC reviews the particular facts of each case and the information on a bank's stock that may be available to it, and from such review selects an appropriate valuation method, or combination of methods, to determine a reasonable estimate of the value of shares. The various valuation methods that the OCC considers are discussed below. Market Value. If there is sufficient trading in the shares and the prices are available from direct quotes from the Wall Street Journal or a market maker, the OCC considers those quotes in determining the market value. If no market value is readily available, or if the market value available is not well established, the OCC may use the investment value or adjusted book value methods of valuation. Investment Value. The OCC determines investment value by looking at peer banks, or institutions of comparable size in the same geographic area with similar earnings patterns. Investment value requires an assessment of the value to investors of a share in the future earnings of the bank and is estimated by applying an average price/earnings ratio of banks with similar earnings potential to the earnings capacity of the bank in question. Adjusted Book Value. Adjusted book value is calculated by multiplying the book value of the bank's assets, on a per share basis, by the ratio of market price to book value for comparable banking organizations. That ratio shows whether the stock of comparable banks sells at a premium or discount to book value. The investment value method and the adjusted book value method present appraised values which are based on the bank's value as a going concern and provide estimates of the market value of the shares of the bank in question. The OCC may use more than one of the above-described methods in determining the value of shares of stock, and if more than one method is used, varying weights may be applied in reaching an overall valuation. The weight given to the value by a particular valuation method is based on the OCC's perception of how accurately the given method is believed to represent market value. 28 Opinion of Bank of Tanglewood's Financial Advisor The fairness opinion of Bank of Tanglewood's financial advisor, Hovde Financial, LLC, is described below. The description contains projections, estimates and/or other forward-looking statements about future earnings or other measures of the future performance of BOK Financial and Bank of Tanglewood. Hovde has reviewed and consented to the following description relating to its opinion. You should not rely on any of these statements as having been made or adopted by BOK Financial or Bank of Tanglewood. Bank of Tanglewood engaged Hovde as its financial advisor on March 21, 2002 in connection with a possible transaction involving Bank of Tanglewood. On May 9, 2002 Hovde delivered to the Bank of Tanglewood board of directors its preliminary written opinion that, as of that date and based upon and subject to the matters set forth in such opinion, the merger consideration described in the merger agreement to be received by the holders of Bank of Tanglewood common stock was fair from a financial point of view to the holders of Bank of Tanglewood common stock. The written opinion was accompanied by an oral presentation to the Bank of Tanglewood board of directors regarding the fairness of the transaction, from a financial perspective. Hovde subsequently confirmed its preliminary opinion by delivering an updated opinion dated the date of this proxy statement-prospectus. Pursuant to an engagement letter between Hovde and Bank of Tanglewood dated March 21, 2002, Bank of Tanglewood agreed to pay to Hovde a transaction fee based on the transaction value and conditioned upon completion of a merger. Assuming the merger is consummated at the merger consideration described in the merger agreement, Bank of Tanglewood and Hovde estimate that Hovde's transaction fee will be equal to approximately $450,000. In addition, Bank of Tanglewood also agreed to reimburse Hovde for its reasonable out-of-pocket expenses related to its rendering of financial advisory and investment banking services to Bank of Tanglewood, including the fees and expenses of its legal counsel. Bank of Tanglewood also agreed to indemnify Hovde and its affiliates, the respective directors, officers, partners, agents and employees of Hovde and its affiliates, and controlling persons for certain losses, claims, damages, liabilities and expenses related to or arising out of its engagement as financial advisor. Hovde's opinions were provided to the Bank of Tanglewood board of directors for its use and benefit and address only the fairness from a financial point of view of the merger consideration to the holders of Bank of Tanglewood common stock. Hovde's opinions do not address the merits of the underlying decision by Bank of Tanglewood to engage in the merger and do not constitute a recommendation to any shareholder as to how that shareholder should vote at the special meeting. The amount and form of consideration to be paid in the transaction was the result of arms-length negotiations between BOK Financial and Bank of Tanglewood. Hovde's preliminary opinion dated May 8, 2002 and its presentation to the Bank of Tanglewood board of directors on May 9, 2002 were among many factors taken into consideration by the Bank of Tanglewood board of directors in making its determination to approve and recommend the transaction described in the merger agreement. Hovde has delivered to Bank of Tanglewood's board its opinion that, based upon and subject to the various considerations set forth in its updated written opinion dated the date of this proxy statement-prospectus, the consideration is fair from a financial point of view to the holders of Bank of Tanglewood common stock as of such date. In requesting Hovde's advice and opinion, no limitations were imposed by Bank of Tanglewood upon Hovde with respect to the investigations made or procedures followed by it in rendering its opinion. The full text of the opinion of Hovde, dated the date of this proxy statement-prospectus, which describes the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached hereto as Annex VIII. Bank of Tanglewood shareholders should read this opinion in its entirety. Hovde is a nationally recognized investment banking firm and, as part of its investment banking business, is continually engaged in the valuation of financial institutions in connection with mergers and acquisitions, private placements and valuations for other purposes. As a specialist in securities of financial institutions, Hovde has 29 experience in, and knowledge of, banks, thrifts and bank and thrift holding companies. Bank of Tanglewood's board of directors selected Hovde to act as its financial advisor in connection with the merger on the basis of the firm's reputation and expertise in transactions such as the merger. Hovde will receive a fee contingent upon the completion of the merger for services rendered in connection with advising Bank of Tanglewood regarding the merger, including the fairness opinion and financial advisory services provided to Bank of Tanglewood. As of the date of this proxy statement-prospectus, such fee is approximately $450,000 and Hovde has received $112,500 of such fee. Hovde's opinion is directed only to the fairness, from a financial point of view, of the consideration, and does not constitute a recommendation to any Bank of Tanglewood shareholders as to how the shareholder should vote at the Bank of Tanglewood meeting. The summary of the opinion of Hovde set forth in this proxy statement-prospectus is qualified in its entirety by reference to the full text of the opinion. The following is a summary of the analyses performed by Hovde in connection with its fairness opinion. Certain of these analyses were presented to the Bank of Tanglewood board of directors by Hovde in a preliminary written report and in an oral presentation on May 9, 2002 and were subsequently updated and confirmed in its written opinion dated September 19, 2002. The summary set forth below does not purport to be a complete description of either the analyses performed by Hovde in rendering its opinion or the presentation made by Hovde to the Bank of Tanglewood board of directors, but it does summarize all of the key material analyses performed and presented by Hovde. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial analyses and the application of those methods to the particular circumstances. In arriving at its opinion, Hovde did not attribute any particular weight to any analysis and factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Hovde may have given various analyses more or less weight than other analyses. Accordingly, Hovde believes that its analyses and the following summary must be considered as a whole and that selecting portions of its analyses, without considering all factors and analyses, could create an incomplete view of the process underlying the analyses set forth in its report to the Bank of Tanglewood board and its fairness opinion. In performing its analyses, Hovde made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Bank of Tanglewood and BOK Financial. The analyses performed by Hovde are not necessarily indicative of actual value or actual future results, which may be significantly more or less favorable than suggested by such analyses. Such analyses were prepared solely as part of Hovde's analysis of the fairness of the consideration, from a financial point of view, to the Bank of Tanglewood shareholders. The analyses do not purport to be an appraisal or to reflect the prices at which a company might actually be sold or the prices at which any securities may trade at the present time or at any time in the future. Hovde's opinion does not address the relative merits of the merger as compared to any other business combination in which Bank of Tanglewood might engage. In addition, as described above, Hovde's opinion to the Bank of Tanglewood board was one of many factors taken into consideration by the Bank of Tanglewood board in making its determination to approve the merger agreement. During the course of its engagement, and as a basis for arriving at its opinion, Hovde reviewed and analyzed material bearing upon the financial and operating condition of Bank of Tanglewood and BOK Financial and material prepared in connection with the merger, including, among other things, the following: the merger agreement; certain historical publicly available information concerning Bank of Tanglewood and BOK Financial, including as applicable: Bank of Tanglewood and BOK Financial's audited consolidated financial statements, documents filed with the Securities and Exchange Commission, the Federal Deposit Insurance Corporation, the Federal Reserve, and other state or other regulatory agencies; recent internal reports and projections regarding Bank of Tanglewood; the nature and terms of recent sale and merger transactions involving banks and bank 30 holding companies that Hovde considered relevant, as well as its knowledge of the commercial banking industry and its general experience in securities valuations; and financial information provided to us by the management teams of both Bank of Tanglewood and BOK Financial. In rendering the fairness opinion, Hovde assumed and relied upon the accuracy and completeness of the financial and other information provided to it by Bank of Tanglewood or BOK Financial without assuming any responsibility for independent verification of such information and further relied upon the assurance of the managements of BOK Financial and Bank of Tanglewood that they were not aware of any facts or circumstances that would make such information, provided by them, inaccurate or misleading. With respect to financial statements and/or projections to the extent such were provided by Bank of Tanglewood and BOK Financial, Hovde assumed that such financial statements and/or projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the respective managements of Bank of Tanglewood and BOK Financial. Hovde assumed that the merger would be accounted for using the purchase method of accounting. In rendering the fairness opinion, Hovde did not conduct a physical inspection of the properties and facilities of Bank of Tanglewood or BOK Financial and did not make or obtain any evaluations or appraisals of the assets or liabilities of Bank of Tanglewood or BOK Financial. In addition, Hovde noted that it is not an expert in the evaluation of loan portfolios or allowances for loan, lease or real estate owned losses, and it assumed that the allowances for loan, lease and real estate owned losses (as currently stated or as adjusted for in connection with the merger or otherwise) provided to it by Bank of Tanglewood and used by it in its analysis and in rendering its fairness opinion were in the aggregate adequate to cover all such losses. The fairness opinion was based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date the fairness opinion. Merger Value Analysis. The total value of the consideration offered by BOK Financial to Bank of Tanglewood is $65.0 million in BOK Financial common stock. This $65.0 million merger consideration includes approximately $450,000 to be paid to Hovde as Bank of Tanglewood's financial advisor and assumes the issuance to Bank of Tanglewood shareholders of the $750,000 in BOK Financial common stock to be placed into the escrow account to compensate BOK Financial for any breaches in representations and warranties of Bank of Tanglewood in the merger agreement which are discovered between completion of the merger and December 31, 2003. The $65 million merger consideration excludes the value of the benchmark price protection rights. The value of the stock has been supplemented by the benchmark price protection provision. The benchmark price protection was not taken into consideration by Hovde in rendering its fairness opinion. Hovde calculated the price-to-book value, the price-to-last twelve months earnings multiple (LTM), the price-to-assets, and the premium-to-core deposits using the following values as of December 31, 2001 for Bank of Tanglewood: Book Value of $15,672,000; Twelve Months Trailing Earnings of $2,024,000; Total Assets of $250,204,000; and Total Core Deposits of $191,601,000. The deal value metrics equate to 432.0% of tangible book value, 32.1x LTM earnings, 26.0% of assets and 25.8% premium to core deposits. 31 Analysis of Selected Mergers. As part of its analysis, Hovde reviewed comparable mergers involving banks in the west and southwest (states for southwest and west include CO, LA, NM, OK, TX, AK, AZ, CA, HI, ID, MT, NV, OR, WA, WY) announced between June 30, 2000 and September 10, 2002 in which the selling institution had assets between $150 million and $500 million and a return on assets of at least 1.0% and a return on equity of at least 10.0% over the last twelve months.

(TX) Hovde calculated the medians for "Merger Group 1" and averages for the "Purchase Merger Group" for the following relevant transaction ratios: the percentage of the offer value to the acquired company's total assets; the multiple of the offer value to the acquired company's earnings per share for the twelve months preceding the announcement date of the transaction; the multiple of the offer value to the acquired company's tangible book value per share; and the tangible book value premium to core deposits, each as of the announcement date of the transaction. Hovde compared these multiples with the corresponding multiples for the proposed Bank of Tanglewood merger. In calculating the multiples for the merger, Hovde used Bank of Tanglewood's earnings per share for the 12 months ended December 31, 2001 and Bank of Tanglewood's tangible book value per share, total assets and total deposits as of December 31, 2001. The results of this analysis are as follows: Offer Value to: --------------------------- 12 months Ratio of Tangible Tangible Preceding Book Value Total Book Value Earnings Premium to Core Assets Per Share Per Share Deposits (%) (x) (x) (%) ------ ---------- --------- ----------------- Bank of Tanglewood........... 25.98 4.32 32.11 25.75 Merger Group 1 High.......... 31.76 3.69 23.94 32.14 Merger Group 1 Median........ 22.57 2.67 17.61 19.64 Merger Group 1 Low........... 11.67 1.37 9.10 4.58 Purchase Merger Group High... 29.83 5.13 57.56 34.61 Purchase Merger Group Average 17.75 2.11 22.35 11.91 Purchase Merger Group Low.... 7.85 1.12 10.42 1.48 33 Comparable Company Analysis. Using publicly available information, Hovde compared the financial performance and potential stock market valuation for BOK Financial with the following publicly traded banks located in the United States with assets between $5 billion and $20 billion that have a return on average assets greater than 1.0% and a return on average equity greater than 10.0% over the last twelve months and price-to-Institutional Brokers Estimate System estimated 2002 earnings greater than 13 times : Total Assets Company Name ($Thousands) ------------ ------------ Associated Banc-Corp (WI)............ 14,327,900 City National Corporation (CA)....... 11,217,349 Commerce Bancorp, Inc.

Hovde estimated the present value of the Bank of Tanglewood by starting with earnings of $2.0 million in 2001 and assuming a 8.0% annual growth rate in earnings and a 10.0% annual growth rate in assets through 2007 (resulting in net income of $3.4 million, $3.9 million, $4.8 million, $5.2 million, $5.8 million and $6.3 million in 2002, 2003, 2004, 2005, 2006, and 2007 respectively). In arriving at the present value of Bank of Tanglewood's earnings stream at the end of 2007, Hovde assumed an annual discount rate of 16.0%. This analysis and its underlying assumptions yielded a range of values for Bank of Tanglewood of approximately $37.7 million to $61.5 million compared to a total merger consideration of $65.0 million offered by BOK Financial. The $65.0 million merger consideration includes approximately $450,000 to be paid to Hovde as Bank of Tanglewood's financial advisor and assumes the issuance to Bank of Tanglewood shareholders of the $750,000 in BOK Financial common stock to be placed into the escrow account to compensate BOK Financial for any breaches in representations and warranties of Bank of Tanglewood in the merger agreement which are discovered between completion of the merger and December 31, 2003. The $65 million merger consideration excludes the value of the benchmark price protection rights and such value is not considered for purposes of this analysis. 34 Contribution Analysis. Hovde prepared a contribution analysis showing percentages of assets, loans, deposits, common equity, tangible equity, cash earnings and generally accepted accounting principles (GAAP) earnings based on December 31, 2001 financial data for Bank of Tanglewood and BOK Financial that would be contributed to the combined company on a pro forma basis by Bank of Tanglewood and BOK Financial. BOK Financial Bank of Tanglewood ------------- ------------------ Total Assets......... 98.14% 1.86% Total Deposits....... 96.89% 3.11% Total Equity......... 98.14% 1.86% Total Tangible Equity 97.36% 2.64% Cash Earnings........ 97.67% 2.33% GAAP Earnings........ 97.30% 2.70% Conclusion. Based upon the foregoing analyses and other investigations and assumptions set forth in its opinion, without giving specific weightings to any one factor or comparison, Hovde determined that the consideration was fair from a financial point of view to the Bank of Tanglewood shareholders. Directors and Management Following the Merger After the merger, the combined TW Interim National Bank and Bank of Tanglewood, N.A. will be known as Bank of Tanglewood, N.A. and will be headquartered in Houston, Texas. The Bank of Tanglewood management and board of directors will continue to manage the business of Bank of Tanglewood. The management and board of directors of BOK Financial shall remain unchanged following the merger, with the exception of Robert G. Greer, who shall be appointed as an advisory member of the BOK Financial board of directors and thereafter nominated for election as a voting director of BOK Financial at the 2003 annual meeting of shareholders. Subsequent to the merger, Mr. Greer will also be elected a director of Bank of Texas, N.A., a wholly owned subsidiary of BOK Financial. Robert G. Greer, age 68, is the chairman of the board of directors of Bank of Tanglewood, a position he has held since Bank of Tanglewood opened in December 1996. From 1985 to 1995 he served as chairman of the board of Tanglewood Bank, N.A., and then as vice chairman of the board of Northern Trust Bank of Texas from 1995 to 1996. Executive Compensation The following table provides certain summary information concerning compensation paid to or accrued by Bank of Tanglewood to or on behalf of Bank of Tanglewood's Chairman of the Board, Robert G. Greer: SUMMARY COMPENSATION TABLE Annual Compensation -------------------- Other Annual All Other Name and Principal Position Year Salary Bonus Compensation Compensation --------------------------- ---- ------- ------- ------------ ------------ Robert G. Greer......... 2001 $75,000 $40,937 $13,448(1) $3,682(2) Chairman of the Board -------- (1) Consists of a car allowance of $6,900 and club dues of $6,548. (2) Consists of contributions made by Bank of Tanglewood to its 401(k) Plan for the benefit of Mr. Greer. 35 Financial Interests of Bank of Tanglewood Directors and Officers in the Merger Certain of Bank of Tanglewood's directors and executive officers have interests in the merger as individuals in addition to, and that may be different from, your interests as shareholders. Each of the Bank of Tanglewood board of directors and the BOK Financial board of directors was aware of these interests of certain Bank of Tanglewood directors and executive officers and considered them in its decision to adopt the merger agreement. Stock Option Plan. A stock option plan was adopted by the Bank of Tanglewood board of directors and approved by shareholders in November 1996. The plan has been amended on several occasions. Subject to adjustment as provided in the plan, there are currently 173,000 shares of common stock reserved for issuance pursuant to the exercise of options granted under the plan. A total of 166,950 options are presently outstanding to bank officers and employees at exercise prices ranging from $10.00 and $35.00 per share. Of these options, 121,250 have vested, and are currently exercisable in accordance with their terms. Under the terms of the stock option plan, the unvested options will become vested options on the effective date of the merger. Pursuant to the terms of the merger agreement, each option holder has executed an amendment to his or her respective stock option agreement to provide that any outstanding incentive option shall no longer be an incentive option for purposes of the Internal Revenue Code, that each option shall expire 120 days after the completion of the merger and that the optionee shall not exercise the option until after completion of the merger. The exercise of the options by the optionees will increase the capital of BOK Financial by the amount of the aggregate exercise price (approximately $2.3 million) and result in a compensation expense deduction of approximately $7.6 million for BOK Financial and a corresponding amount of compensation income to the persons exercising such options. In consideration of the amendment of the stock option agreements by the option holders, the merger agreement allows Bank of Tanglewood to pay to the option holders on a pro rata basis an aggregate amount of $740,000. Phantom Stock Agreements. In November 2001 and March 2002, Bank of Tanglewood entered into Phantom Stock Agreements with 11 of its officers. These agreements were established as part of the bank's long-term incentive compensation programs for its officers and employees. While no shares of bank stock will be issued under the agreements, the grantees are entitled to certain cash payments calculated pursuant to the terms of the agreements. Under these agreements, each participant was granted a number of shares of "phantom stock" with an "award value" per share; the award value was $25 per share in the case of Messrs. Greer, Jochetz and Tidwell and $30 to $35 per share for the other officers. Each agreement provides that 20% of the shares of phantom stock will vest on the fourth anniversary of the agreement and thereafter 20% will vest on each of the next four anniversaries. However, upon a change in control of the bank, such as the merger with BOK Financial, the normal vesting schedule of the phantom stock shares is accelerated and each owner of phantom shares becomes entitled to payment for such shares. The amount paid by the bank for each share of phantom stock is equal to the amount that the value of one share of bank common stock exceeds the award value. If the merger with BOK Financial is completed, the aggregate amount to be paid pursuant to the Phantom Stock Agreements will be $2,069,305, with Messrs. Greer, Jochetz and Tidwell receiving an aggregate of $1,532,260 of the total amount of payments. Employment Agreement Summary. Bank of Tanglewood and BOK Financial entered into employment agreements with Messrs. Greer, Jochetz and Tidwell, as well as several other officers, on May 15, 2002 concurrently with the execution of the merger agreement. Implementation of the employment agreements is subject to the condition that BOK Financial shall have acquired Bank of Tanglewood in accordance with the terms of the merger agreement. Each employment agreement provides the terms of employment for each executive, including the duration of the employment agreement, title and duties, compensation and benefits, termination provisions and non- 36 competition and non-solicitation provisions (except that Mr. Tidwell's contract does not contain non-competition and non-solicitation provisions). The executives will be employed by Bank of Tanglewood following its acquisition by BOK Financial and subsequently by Bank of Texas after Bank of Tanglewood is merged into Bank of Texas, N.A. If an executive's employment is terminated "without cause" during the term of the employment agreement, the executive will continue to receive the annual salary provided in the agreement, any "mandatory" performance compensation and employee benefits for the remainder of the contract term, and any unvested stock options which would otherwise have vested during the term of the contract shall vest at the termination date and be exercisable by the executive. An executive's employment may also be terminated "for cause", defined in the employment agreement to include such things as: . willful failure to substantially perform the obligations under the agreement; . commission of any act which is intended to materially injure the bank; . conviction of any criminal act or act involving moral turpitude; . commission of any dishonest or fraudulent act which bank reasonably deems material to the bank or its reputation; . refusal to obey written orders or instructions of the chief executive officer of the bank, unless those instructions would require the executive to commit an illegal act which would subject the executive to personal liability, require the executive to violate the terms of his employment agreement or otherwise be inconsistent with the duties of an officer of a national bank. The majority of the board of directors of the bank must determine (after giving the executive an opportunity to be heard) that the executive has committed one of these acts to have cause for termination. Upon a termination for cause, any compensation and benefits will be paid to the executive only through the date of termination. Terminations due to death or an extended illness are treated similar to terminations for cause. The contracts of Messrs. Jochetz and Greer contain non-competition and non-solicitation provisions that govern such executives' actions following termination of employment. With respect to such provisions, both executives will receive separate additional consideration of $10,000 upon completion of the merger. The non-competition provisions provide that for a period of two years after termination, an executive shall not engage in the banking business or any business in which the bank or an affiliate of the bank has engaged in Harris County, Texas or in any county in which the bank maintains a banking office for which such executive has supervisory authority, or any counties contiguous to any such counties. Mr. Jochetz's agreement (but not Mr. Greer's) further provides that if his employment is terminated without cause following a change of control (as defined in the employment agreement) of the bank, the non-competition provisions shall, at his option, no longer be applicable. The non-solicitation provisions in Mr. Jochetz's contract provide that for a period of three to five years following termination (depending on the length of time which Mr. Jochetz has been employed by Bank of Tanglewood or its successors prior to his termination of employment), he cannot contact or solicit individuals or entities who were clients of the Bank of Tanglewood or its affiliates in the same geographic area covered by the non-competition provisions for the purpose of providing banking services or contact or solicit employees of the bank or its affiliates to seek employment with any person or entity other than the bank or its affiliates. Mr. Greer has agreed to a five-year non-solicitation term. For each year in which both the non-competition and non-solicitation clauses are in effect, Mr. Jochetz will receive a payment equal to 75% of his annual salary at the date of termination of his employment, and Mr. Greer will be paid $50,000 annually. In addition, Mr. Greer will be paid $25,000 per year for each year that only the non-solicitation agreement is in effect and Mr. Jochetz will be paid 29% of his annual salary at the date of termination for each year that only the non-solicitation agreement is in effect. 37 Set forth below is a summary of the compensation provisions and certain other terms of the respective employment agreements for Bank of Tanglewood's executive officers: Robert G. Greer will serve as Chairman of the Board of Directors of Bank of Tanglewood (and subsequently as Vice Chairman of the Board of Directors of the Bank of Texas) at an annual salary of $106,500 (with a 3% per annum increase) for a term of five years; performance bonus in the amount of at least $45,000 for the years 2002 through 2007. Mr. Greer will also be entitled to participate in the BOK Financial stock option plan with a grant of options to acquire at least 3,000 shares of BOK Financial common stock in 2002 and will receive other customary benefits. Richard W. Jochetz will serve as President and Chief Executive Officer of the Tanglewood Division of Bank of Texas at an annual salary of $172,000 (with a 3% per annum increase) for a term of three years; performance bonus in the amount of at least $70,000 for 2002 and $70,000 for 2003. Mr. Jochetz will also be entitled to participate in the BOK Financial stock option plan with a grant of options to acquire at least 5,000 shares of BOK Financial common stock in 2002 and will receive other customary benefits. James L. Tidwell will serve as Executive Vice President and Chief Financial Officer of the Tanglewood Division of Bank of Texas at an annual salary of $135,500 (with a 3% per annum increase) for a term of eighteen months; performance bonus in the amount of at least $58,000 for 2002 and will receive other customary benefits. Indemnification and Insurance. The merger agreement generally provides that BOK Financial will indemnify and hold harmless present and future directors, officers and employees of Bank of Tanglewood to the fullest extent allowable by the provisions of the BOK Financial amended and restated certificate of incorporation and bylaws. BOK Financial will also cause Bank of Tanglewood to purchase an extended discovery period under the existing Bank of Tanglewood directors and officers liability policy, or provide a comparable policy, for three years following the closing of the merger. The indemnification rights, as well as the limitation of liability existing in favor of such persons in the Bank of Tanglewood's articles of association, continue after the closing with respect to claims arising from facts or events that occurred before the closing. Employee Benefits. After the effective time of the merger, BOK Financial will provide to officers and employees of Bank of Tanglewood who become officers or employees of BOK Financial or one of its subsidiaries, employee benefits under employee benefit plans (other than stock option or other plans involving the potential issuance of BOK Financial common stock) on terms and conditions that, taken as a whole, are substantially similar to those currently provided by BOK Financial and its subsidiaries to their similarly situated officers and employees. For purposes of participation and vesting (but not accrual of benefits) under employee benefit plans for which Bank of Tanglewood had a substantially similar employee benefit plan, service with Bank of Tanglewood prior to the effective time of the merger will be treated as service with BOK Financial or its subsidiaries. With regard to BOK Financial employee benefit plans for which there was no Bank of Tanglewood equivalent, service with Bank of Tanglewood prior to the effective time of the merger will not be treated as service with BOK Financial and its subsidiaries. The merger agreement further provides that BOK Financial will cause the bank to honor all employment, severance, consulting and other compensation contracts previously disclosed to BOK Financial between Bank of Tanglewood and any current or former director, officer or employee, and all provisions for vested amounts earned or accrued through the effective time of the merger under Bank of Tanglewood's benefit plans. New BOK Financial Director and Bank of Texas Director. BOK Financial has agreed to elect Mr. Greer as an advisory member to the BOK Financial board of directors until he may be nominated to be a voting director for the 2003 annual BOK Financial shareholders meeting. Mr. Greer is also to be elected as a director of Bank of Texas, a wholly owned subsidiary of BOK Financial. Transferability of Shares of BOK Financial Common Stock All shares of BOK Financial common stock that Bank of Tanglewood shareholders will receive in the merger will be freely transferable, except for shares of BOK Financial common stock that are received by 38 persons who are deemed to be "affiliates" of Bank of Tanglewood under the Securities Act at the time of the Bank of Tanglewood shareholder meeting. Persons who may be deemed to be affiliates of Bank of Tanglewood for the above purposes generally include individuals or entities that control, are controlled by or are under common control with Bank of Tanglewood, and include directors and certain executive officers of Bank of Tanglewood. Persons considered affiliates may resell the shares of BOK Financial common stock they receive in the merger only pursuant to an effective registration statement, in transactions permitted by Rule 145 adopted by the SEC under the Securities Act or as otherwise permitted under the Securities Act. Under Rule 145, during the first calendar year after the merger becomes effective, affiliates of Bank of Tanglewood may publicly resell the BOK Financial common stock they receive in the merger, but only within certain limitations as to the number of shares they can sell in any three-month period and as to the manner of sale. After the one-year period, affiliates of Bank of Tanglewood who are not affiliates of BOK Financial may resell their shares without restriction as long as BOK Financial continues to satisfy its reporting requirements under the Securities Exchange Act of 1934. The merger agreement requires that Bank of Tanglewood use commercially reasonable efforts to cause each of these affiliates to deliver to BOK Financial, within 30 days of the closing date (and in any event prior to the effective time), a written agreement to the effect that these persons will not sell, transfer or otherwise dispose of any of the shares of BOK Financial common stock issued to them in the merger in violation of the Securities Act or the related SEC rules. This document does not cover any resales of the BOK Financial common stock received in the merger, and no person is authorized to make any use of this document in connection with any such resales. 39 THE MERGER AGREEMENT The following information summarizes the material terms of the merger agreement, as amended, a conformed copy of which is attached as Annex I to this document and is incorporated herein by reference. We urge you to read the merger agreement in its entirety for a more complete description of the terms and conditions of the merger. The Merger Under the merger agreement, Bank of Tanglewood will merge with TW Interim National Bank, a wholly-owned subsidiary of BOK Financial. The merger will become effective on the date which is five business days after the first day on which BOK Financial may complete the acquisition under applicable law and the merger of the resulting bank into Bank of Texas, N.A. may be consummated. Conversion Ratio At the time of the merger, each share of Bank of Tanglewood common stock shall automatically be converted into that number of shares of BOK Financial common stock equal to the conversion ratio. The conversion ratio equals (1) a number of shares of BOK Financial common stock having an aggregate market value of $65,000,000 (less $450,000 in transaction costs) divided by the 30 day average trading price of BOK Financial common stock, divided by (2) the total number of shares of Bank of Tanglewood common stock outstanding and shares reserved for issuance pursuant to outstanding stock options. For these purposes, the 30-day average trading price is the average of the mid-points between the highest price and the lowest price at which a trade occurs (or, in the event of a single trade, the price of such trade) for BOK Financial common stock on NASDAQ on the 30 trading days on which at least one trade actually occurred, immediately preceding the merger closing date. Based upon the average trading price of BOK Financial common stock for the 30 trading days ending on September 17, 2002 of $32.84, Bank of Tanglewood shareholders and option holders would receive up to 1.72 shares of BOK Financial common stock for each share of Bank of Tanglewood common stock they own or may acquire by exercising options. Of this amount, 1,658,411 shares of BOK Financial common stock will be issued upon completion of the merger and 22,838 shares would be deposited into an escrow account for possible future distribution to Bank of Tanglewood shareholders and exercising option holders. Exchange of Shares As soon as practicable after the effective time of the merger, the exchange agent, SunTrust Bank, will mail you a letter of transmittal and instructions for exchanging your Bank of Tanglewood stock certificates for BOK Financial stock certificates. You should not send in your certificates until you receive a letter of transmittal and instructions. Fractional shares of BOK Financial common stock will not be issued to holders of Bank of Tanglewood common stock. For each fractional share of BOK Financial common stock that would otherwise be issued, the holder will instead receive a full share of BOK Financial common stock. After you surrender to the exchange agent one or more certificates for Bank of Tanglewood common stock, together with a properly completed letter of transmittal, the exchange agent will (1) issue and mail to the holder a certificate representing the number of whole shares of BOK Financial common stock to which the holder is entitled and (2) issue and mail to Bank of Texas, as escrow agent, the $750,000 in shares of BOK Financial common stock to be held in escrow pursuant to the escrow agreement. The exchange agent may issue a certificate for BOK Financial common stock in a name other than the name in which the surrendered certificate is registered only if (a) the certificate surrendered is properly endorsed or is otherwise in proper form for transfer and (b) the 40 person requesting the issuance of the certificate either pays to the exchange agent any transfer or other taxes required by the issuance of a certificate for shares in a name other than the registered holder of the certificate surrendered or establishes to the satisfaction of the exchange agent that the taxes have been paid or are not due. All BOK Financial common stock issued in the merger will be deemed issued as of the effective time of the merger. No dividends with respect to the BOK Financial common stock with a record date after the effective time will be paid to the former shareholders of Bank of Tanglewood entitled to receive certificates for shares of BOK Financial common stock until such shareholders surrender their certificates representing shares of Bank of Tanglewood common stock. After the certificates are surrendered, BOK Financial will pay the shareholder of record any dividends, without any interest thereon, which become payable with respect to the shares of BOK Financial common stock represented by the certificate, other than those shares to be held in escrow. If your certificate for Bank of Tanglewood common stock is lost, stolen or destroyed, the exchange agent will issue the shares of BOK Financial common stock upon your submission of an affidavit by you claiming the certificate to be lost, stolen or destroyed. Upon completion of the merger, you will cease to have any rights as a shareholder of Bank of Tanglewood. Until so surrendered, each certificate will be deemed for all corporate purposes to represent and evidence solely the right to receive the consideration to be paid pursuant to the merger agreement. Neither BOK Financial, Bank of Tanglewood, the exchange agent nor any other party will be liable to any holder of certificates for any amount paid to a public official pursuant to any applicable abandoned property, escheat or similar law. Benchmark Price Protection BOK Financial will provide benchmark price protection for 50% of the shares to be issued in the merger (including BOK Financial common stock to be issued pursuant to Bank of Tanglewood stock options). This benchmark price protection consists of the following: . Following each benchmark period, BOK Financial will, subject to the limitations described below, make a benchmark payment to the former Bank of Tanglewood shareholders and stock option holders who sold BOK Financial common stock received in the transaction. . The benchmark price protection is limited at each benchmark date to 10% of the total BOK Financial shares received by such holder in the transaction. If you do not exercise your 10% benchmark price protection in any benchmark period, you will not be able to carry forward that 10% benchmark price protection right into subsequent benchmark periods. . The benchmark payment will be an amount equal to the difference between a benchmark target price and the price at which the former Bank of Tanglewood shareholder or stock option holder sold the BOK Financial common stock issued in the merger or pursuant to stock option exercises. Sales must be made during the benchmark period which is the sixty calendar day period immediately following each benchmark date. . BOK Financial may make the benchmark payment either in cash or in BOK Financial common stock. BOK Financial is not obligated to issue cash. In the event BOK Financial elects to issue stock, the total number of shares of BOK Financial common stock that BOK Financial is obligated to issue, for all benchmark dates to all such holders, is limited to 10,000,000. If, as of any benchmark date, BOK Financial has already issued 10,000,000 shares, BOK Financial is not obligated to make any further benchmark payment. . The benchmark dates are the first, second, third, fourth and fifth anniversary dates of the closing of the merger. We currently anticipate that the closing of the merger will occur on or about October 25, 2002, but this is subject to change. 41 . The benchmark target price is the BOK Financial common stock market value (as defined in the merger agreement) on the closing date times the applicable benchmark price multiple, as follows: Benchmark Benchmark Date Price Multiple -------------- -------------- First..... 1.08 Second.... 1.16 Third..... 1.24 Fourth.... 1.32 Fifth..... 1.40 . To be eligible for a benchmark payment, the former Bank of Tanglewood shareholders or stock option holders must advise BOK Financial, not later than 75 calendar days following the applicable benchmark date, of the number, price and date of BOK Financial shares sold by such holder, together with reasonable supporting documentation. . The rights to benchmark price protection are personal to the holders who received the BOK Financial common stock in the merger or by option exercise and may not be assigned or transferred (except by operation of law or intestacy). . The rights to benchmark price protection will not be evidenced by any certificate or other indicia of ownership. BOK Financial will maintain records of the number of BOK Financial shares received by each Bank of Tanglewood shareholder and option holder. You should also maintain your own records regarding the number of BOK Financial shares issued to you in the transaction. . If any BOK Financial share is sold at a price less than the lowest price of a transaction in BOK Financial common stock on NASDAQ on the date of sale, the benchmark payment shall be based on a deemed sale price equal to such lowest price of a transaction on NASDAQ on the date of sale. . The shares of BOK Financial common stock deposited into the escrow account are not to be entitled to the benchmark price protection. Should you have any questions regarding the number of your shares subject to the benchmark price protection, exercising your benchmark price protection rights or any other matter related to the benchmark price protection, you may contact BOK Financial's Investor Relations Director, who at the time of this mailing is James F. Ulrich, at (918) 588-6000. The benchmark price protection has a theoretical value of $1.30 per share of BOK Financial common stock issued in the transaction using the Black-Scholes Option Pricing Model. The calculation of the $1.30 theoretical value of the benchmark price protection is based on the following assumptions: $32.84 underlying price; 19.5% volatility factor; 2.35% average risk-free rate of return; no dividends. Black-Scholes is a model that computes a theoretical value for stock options based upon assumptions such as the expected dividend yield and volatility of BOK Financial common stock, a risk-free rate of return and the average lives of the options. This model was developed to estimate the fair value of traded options that have no vesting restrictions and are fully transferable. The benchmark price protection has characteristics that are significantly different from such options, including the facts that the options are not traded and are not transferable. Additionally, differences between the actual and assumed data can materially affect the fair value estimates. The ultimate value of the benchmark price protection feature may differ significantly from this estimated value. Escrow At closing, BOK Financial shall deposit into an escrow account a number of shares of BOK Financial common stock having a market value of $750,000, taken from the shares that were to be delivered to Bank of Tanglewood shareholders pursuant to the merger agreement. The number of BOK Financial shares deliverable into escrow shall be prorated between the Bank of Tanglewood shareholders (excluding any dissenting shares 42 and based on the number of shares of Bank of Tanglewood common stock owned by each shareholder) and the stock option holders on the closing date, rounded up to the nearest whole share. The escrow agent shall be Bank of Texas Trust Company, National Association. Based on an assumed conversion ratio of 1.72, you would receive for each share of Bank of Tanglewood common stock you own or options you exercise, 1.70 shares of BOK Financial common stock would be issued to you upon completion of the merger and .02 shares of BOK Financial common stock would be placed in the escrow account on your behalf. In the event BOK Financial claims a breach of the representations and warranties of Bank of Tanglewood in the merger agreement and suffers a loss related to such breach, BOK Financial shall give notice of the claim to the Bank of Tanglewood agent. In the event BOK Financial makes a claim prior to December 31, 2003, the escrow agent shall continue to hold the escrow shares until such claim(s) is resolved by (1) mutual agreement between the Bank of Tanglewood agent and BOK Financial or (2) a final adjudication determining the merits of the claim(s) at which time the escrow agent shall pay the claim as mutually agreed or finally adjudicated. The escrow agent shall make a claim payment by delivering to BOK Financial out of the escrow that number of escrow shares which is determined by dividing the amount of the allowed claim expressed in dollars by the BOK Financial common stock market value determined on the date of the claim payment. The initial Bank of Tanglewood agent shall be Richard W. Jochetz. The shareholders may by vote of a majority in interest and upon notice to BOK Financial, change the agent. The escrow shall terminate on the later of December 31, 2003 or the date on which all timely noticed claims have been resolved by mutual agreement or final adjudication and all allowed claims, if any, shall have been paid to BOK Financial. Upon termination of the escrow, the escrow shares remaining, if any, shall be prorated and delivered to the former shareholders of Bank of Tanglewood and the former option holders who exercised their options. The rights of Bank of Tanglewood shareholders and stock option holders to receive escrow shares shall not be assignable or transferable except by operation of law or by intestacy or with the approval of BOK Financial (which approval shall not be unreasonably withheld, delayed or denied). Bank of Tanglewood Stock Option Plan; Phantom Stock Agreements Effective as of the closing date, BOK Financial shall assume the Bank of Tanglewood 1996 Stock Option Plan and each option to buy one share of Bank of Tanglewood common stock pursuant to the Tanglewood 1996 Stock Option Plan shall automatically be converted into the right to acquire shares of BOK Financial common stock. The number of shares of BOK Financial common stock purchasable under each converted option and the exercise price of these converted options will be adjusted to reflect the conversion ratio and will be subject to the escrow. Stock option holders having at least ninety-seven percent (97%) of the outstanding stock options and Bank of Tanglewood have agreed in writing, subject to completion of the merger, that: . the stock options shall automatically be converted into BOK Financial stock options that do not constitute Incentive Stock Options within the meaning of Section 422 of the Internal Revenue Code; . the stock options may not be exercised until the closing has been consummated; and . the stock options shall either be exercised within one hundred twenty (120) calendar days following the closing or the stock options shall terminate. As of the date of this proxy statement-prospectus, this condition has been met. 43 Promptly following the merger, BOK Financial intends to register with the Securities and Exchange Commission the shares of BOK Financial common stock issuable upon the exercise of these converted options. Unless these shares of BOK Financial common stock are acquired by an affiliate of Bank of Tanglewood, following registration, the shares issued upon the exercise of the options will be freely tradeable. Prior to closing, Bank of Tanglewood has agreed to make payment under all Phantom Stock Agreements, at a value of $58.31 per Phantom Stock Share, including any payments waived by Messrs. Greer, Jochetz and Tidwell which may be approved by Bank of Tanglewood shareholders at the special meeting. Such payment will constitute full and final payment of all sums due or which could become due under the Phantom Stock Agreements.

Amendment and Waiver The merger agreement may be amended or supplemented in writing before the effective time of the merger by BOK Financial and Bank of Tanglewood except as otherwise provided by law. 48 PROPOSAL II--VOTING ON EXECUTIVE PAYMENTS Bank of Tanglewood has various compensation agreements and plans to provide compensation to its officers and employees. These include the Bank of Tanglewood 1996 Stock Option Plan, pursuant to which many bank officers and employees received an award of options to purchase common stock, and the Phantom Stock Agreements between the bank and 11 of its officers. A change of control of the bank, such as the merger, causes rights under the plan and agreements to mature or vest at the time of the change of ownership, rather than pursuant to the normal vesting schedule provided for in the various agreements. Federal income tax law provides that certain "payments" (which may include the value of the early vesting of options) made to executives as a result of a change of ownership of the bank (such as the merger) may be characterized as "parachute payments", which results in the loss of the tax deduction by Bank of Tanglewood with respect to amounts in excess of a defined base amount and subjects such executives to a 20% excise tax on the excess amount. In general, a "parachute payment" is a compensatory payment that is triggered by a change of control of the payor if the aggregate present value of all such payments is at least equal to three times the amount of the recipient's average annual compensation during the five years preceding the change of control (the "base amount"). The payments will not be characterized as "parachute payments", however, if (1) the executives waive their right to receive a portion of the payments which is sufficient to reduce the payments below three times the base amount; (2) receipt by the executives of the waived amount is contingent upon the approval by the holders of more than 75% of the outstanding shares of Bank of Tanglewood common stock (not including shares of such executives and certain other shareholders related to the executives); and (3) such approval is obtained. Three executives (Messrs. Greer, Jochetz and Tidwell) are eligible to receive certain payments upon the consummation of the merger that would constitute parachute payments. To avoid the adverse tax consequences of such payments, the three executives have waived their rights to receive a portion of such amounts ($277,805 in total) and made the payment of this amount subject to shareholder approval. The amount of the payment each executive has waived reduces their respective payments due to the change of ownership to a level where there are no excise taxes or lost corporate deductions. The amount that each executive is entitled to receive under their respective Phantom Stock Agreements, the estimated value attributable to the early vesting as a result of the merger calculated under the parachute payment rules and the minimum amount that each has waived is indicated in the table below. The amount actually waived could be more, based upon the effective date of the merger, published IRS interest rates in effect at that time and other factors that affect the parachute payment calculations. It is not anticipated, however, that actual amounts waived will be significantly larger than the amounts set forth in the table: Value of Phantom Estimated Stock Payable to Value of Phantom Stock Executive Executive Early Vesting Payment Waived --------- ---------------- ------------- -------------- Robert G. Greer...... $333,100 $272,079 $ 29,979 Richard W. Jochetz... $666,200 $544,155 $146,564 James L. Tidwell, Jr. $532,960 $435,324 $101,262 49 In addition to their Phantom Stock Agreements, the executives (as well as a number of other Bank of Tanglewood employees) hold options to purchase Bank of Tanglewood stock. Most of these options are already vested. However, some of the options are not yet vested, but will become vested at the effective date of the merger. The executives' options which will vest early allow the executives to purchase shares of Bank of Tanglewood stock at a price of $15 per share. The table below indicates, for each executive, the number of options that will vest early as a result of the merger, the estimated value of those options and the estimated value attributable to the early vesting as calculated under the parachute payment rules: Number of Options that Estimated Value of Estimated Vest Early Due to Options that Vest Early Value of Early Executive Merger Due to Merger Vesting --------- ---------------------- ----------------------- -------------- Robert G. Greer...... 1,560 $ 78,502 $ 9,626 Richard W. Jochetz... 2,600 $130,836 $16,042 James L. Tidwell, Jr. 1,560 $ 78,502 $ 9,626 If the executives had not waived their right to a portion of the payments, the approximate parachute payments and the approximate amounts that would be disallowed as a corporate tax deduction and would be subject to the 20% excise tax for each executive is indicated in the following table: Approximate Amount Subject to Executive Approximate Parachute Payment Disallowance and 20% Excise Tax --------- ----------------------------- ------------------------------- Robert G. Greer...... $282,000 $196,000 Richard W. Jochetz... $560,000 $419,000 James L. Tidwell, Jr. $445,000 $328,000 Certain officers of Bank of Tanglewood not listed above will receive payments under their respective Phantom Stock Agreements and have options that will vest early as a result of the merger. However, the value of the early vesting of options and Phantom Stock payments is not sufficient to constitute a "parachute payment" and, therefore, approval of the shareholders is not required to avoid adverse tax consequences. The Board of Directors (with Messrs. Greer, Jochetz and Tidwell abstaining) unanimously recommends that you vote to approve the executive payments in the amount of $277,805 and requests that you execute and return the proxy indicating your approval of such payments. Approval of these payments will not affect the value or number of shares of BOK Financial common stock you will receive in the merger. 50 COMPARISON OF RIGHTS OF SHAREHOLDERS OF BANK OF TANGLEWOOD AND BOK FINANCIAL As a result of the merger, the holders of Bank of Tanglewood common stock will become holders of BOK Financial common stock. The rights of the shareholders of BOK Financial will be governed by applicable Oklahoma law, including the Oklahoma General Corporation Act, and by BOK Financial's articles of incorporation and bylaws. Bank of Tanglewood shareholders will cease to be governed by the National Bank Act and the articles of association and bylaws of Bank of Tanglewood. The following summarizes the material differences between the rights of BOK Financial shareholders and Bank of Tanglewood shareholders. The following summaries do not purport to provide a complete description of the specific rights of BOK Financial shareholders under Oklahoma law and BOK Financial's certificate of incorporation and bylaws, as compared with the rights of Bank of Tanglewood's shareholders under the National Bank Act and related regulations and Bank of Tanglewood's articles of association and bylaws. These summaries are qualified in their entirety by reference to the governing corporate instruments of BOK Financial and Bank of Tanglewood to which shareholders are referred and the applicable Oklahoma law and the National Bank Act, as amended, and regulations of the Office of the Comptroller of the Currency.

This section should be read in conjunction with Bank of Tanglewood's audited financial statements and accompanying notes as of December 31, 2001 and 2000 and for each of the two years then ended and its unaudited interim financial statements as of and for the six months ended June 30, 2002 and 2001 which are attached to this proxy statement-prospectus. Overview Net earnings available to common shareholders for the six months ended June 30, 2002 were $1,631,211 or $1.49 per share fully diluted compared with $904,227 or $0.86 per share fully diluted for the six months ended June 30, 2001, an increase of 80%. The increase was primarily due to increased loan volume which was funded by increased deposits. Bank of Tanglewood posted returns on average assets of 1.37% and 1.04% for the six months ended June 30, 2002 and 2001, respectively. The returns on average assets for the years ended December 31, 2001, 2000 and 1999 were 1.00%, 0.79% and 0.62%, respectively. Returns on average equity were 20.04% and 13.47% for the six months ended June 30, 2002 and 2001, respectively, and for the years ended December 31, 2001, 2000 and 1999 were 14.10%, 9.80% and 6.30%, respectively. Total assets at June 30, 2002 were $234.3 million compared with $250.2 million at December 31, 2001, a 6% decrease. This decrease was primarily due to a $35.0 million decrease in investment securities. Total assets at December 31, 2001, 2000 and 1999 were $250.2 million, $155.5 million and $122.1 million, respectively. Increases in total assets, primarily in loans and investment securities, resulted from an increase in deposits during each of these periods. Total loans increased to $134.0 million at June 30, 2002, from $119.0 million at December 31, 2001, an increase of $15.0 million or 13%. Total loans at December 31, 2001, 2000 and 1999 were $119.0 million, $82.2 million and $63.2 million, respectively. Increases in loans reflect business development efforts and the opening of a new banking facility in 1997 and new banking locations in 1999 and 2001. Total deposits at June 30, 2002 were $204.7 million compared with $222.0 million at December 31, 2001, an 8% decrease. Total deposits at December 31, 2000 and 1999 were $139.0 million and $104.9 million, respectively. Deposits, similar to loans, reflect growth from business development efforts and new banking facilities. Shareholders' equity was $17.2 million at June 30, 2002 compared with $15.7 million at December 31, 2001, an increase of $1.5 million or 10%. Shareholders' equity at December 31, 2000 and 1999 was $11.9 million and $10.5 million, respectively. Results of Operations Net Interest Income Net interest income represents the amount by which interest income on interest-earning assets, including securities and loans, exceeds interest expense incurred on interest-bearing liabilities, including deposits and other borrowed funds. Net interest income is the principal source of Bank of Tanglewood's earnings. Interest rate fluctuations, as well as changes in the amount and type of earning assets and liabilities, combine to affect net interest income. Bank of Tanglewood's net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, referred to as a "volume change." It is also affected by changes in yields earned on interest-earning assets and rates paid on interest-bearing deposits and other borrowed funds, referred to as a "rate change." Net interest income was $5.2 million for the six months ended June 30, 2002, compared with $3.5 million for the six months ended June 30, 2001, an increase of $1.7 million or 49%. The increase in net interest income resulted primarily from growth in average earning assets to $225.2 million for the six months ended June 30, 2002, from $165.7 million for the six months ended June 30, 2001, an increase of $59.5 million or 36%. Net interest income totaled $8.0 million in 2001 compared with $5.3 million in 2000 and $3.6 million in 1999, increases of $2.7 million or 52% and $1.7 million or 47%, respectively, primarily due to growth in interest income 57 in 2001 and 2000 of $3.2 million and $3.4 million, respectively. The increase in 2001 compared with 2000 was partially offset by an increase in interest expense of $486,000. Bank of Tanglewood had net interest margins of 4.22%, 4.14% and 3.75% and net interest spreads of 3.49%, 3.19% and 2.87% for 2001, 2000, and 1999, respectively. Notwithstanding market interest rate decreases by the Federal Reserve totaling 275 basis points in 2001, the net interest margin increased 8 basis points during that year. The increase was primarily due to a $62.9 million increase in interest-earning assets and a decrease in the average rate paid on interest-bearing liabilities, which offset the 102 basis point decrease in the yield on interest-earning assets. The following tables set forth for the periods indicated an analysis of net interest income by each major category of interest-earning assets and interest-bearing liabilities, the average amounts outstanding, the interest earned or paid on such amounts, and the average rate earned or paid. The tables also set forth the net interest margin on average total interest-earning assets for the same periods. Bank of Tanglewood had no nonaccruing loans during each of the periods indicated.

The provision for loan losses for the six months ended June 30, 2002 was $155,000 compared with $75,000 for the six months ended June 30, 2001. The increased provision was made in response to the $34.8 million increase in loans from June 30, 2001 to June 30, 2002. For the six months ended June 30, 2002, net charge-offs were $6,531. For the years ended December 31, 2001, 2000 and 1999, Bank of Tanglewood recorded provisions for loan losses of $271,900, $315,600 and $445,000, respectively. Noninterest Income Bank of Tanglewood's primary sources of recurring noninterest income are service charges on deposit accounts and fee income. Noninterest income for the six months ended June 30, 2002 decreased to $483,000 from $544,000 for the six months ended June 30, 2001, a decrease of $61,000 or 11%. The decrease was primarily due to a decrease in mortgage servicing income of $177,000 related to management's decision to discontinue the mortgage servicing operation as of September 30, 2001, when it was sold to a third party. The mortgage servicing operation was discontinued primarily due to the interest rate environment and the high overhead costs associated with this line of business relative to its profit opportunities. Noninterest income for the year ended December 31, 2001 was $1.0 million, an increase of $664,000 or 182% from $364,000 in 2000. The increase reflects a $232,000 increase in mortgage servicing income, a $176,000 increase in investment banking and insurance fee income from Tanglewood Financial Services, Bank of Tanglewood's wholly-owned financial subsidiary. Noninterest income of $364,000 in 2000 was $188,000 or 107% greater than noninterest income of $176,000 in 1999. The increase was primarily due to mortgage servicing income of $105,000 in 2000 compared from no income from this source in 1999. 61 The following table presents, for the periods indicated, the major categories of noninterest income: Six Months Ended June 30, Years Ended December 31, -------------- ------------------------ 2002 2001 2001 2000 1999 ----- ----- ------- ----- ----- (Dollars in thousands) Service charges on deposit accounts.. $ 69 $ 33 $ 80 $ 46 $ 33 Fee income........................... 222 163 344 172 143 Mortgage servicing income............ 10 187 337 105 -- Investment banking and insurance fees 174 161 219 43 -- Realized gain on assets.............. 8 -- 48 (2) -- ---- ---- ------ ---- ---- Total noninterest income.......... $483 $544 $1,028 $364 $176 ==== ==== ====== ==== ==== Noninterest Expense Noninterest expense totaled $3.1 million for the six months ended June 30, 2002 compared with $2.6 million for the six months ended June 30, 2001, an increase of $519,000 or 20%. The opening of the Memorial location in April 2001 and the opening of the operations center in July 2001 account for a majority of the increase. For the years ended December 31, 2001, 2000 and 1999, noninterest expense totaled $5.9 million, $3.9 million and $2.8 million, respectively. The 51% increase in 2001 was primarily the result of additional staff and other expenses needed to meet loan and deposit growth and the opening of the Memorial location and operations center and the overhead associated with the mortgage servicing operation. The 39% increase in 2000 largely reflects the staffing and other expenses related to opening the West University new building in December 1999. Bank of Tanglewood's efficiency ratios, calculated by dividing total noninterest expenses by net interest income plus noninterest income, were 65.6% in 2001, 70.1% in 2000 and 74.7% in 1999. The following table presents, for the periods indicated, the major categories of noninterest expense: Six Months Ended June 30, Years Ended December 31, ---------------- ------------------------ 2002 2001 2001 2000 1999 ------- ------ ------- ------ ------ (Dollars in thousands) Employee compensation and benefits.... $1,591 $1,382 $3,321 $2,303 $1,561 ------ ------ ------ ------ ------ Non-staff expenses: Net bank premises expense.......... 471 387 857 622 545 Office supplies.................... 55 61 135 80 63 Data/Item processing fees.......... 189 150 215 152 106 Mortgage servicing amortization.... -- 112 158 5 -- Legal and professional fees........ 142 72 261 140 132 Marketing.......................... 51 45 61 65 41 FDIC insurance..................... 18 12 27 22 9 Other.............................. 633 410 823 478 328 ------ ------ ------ ------ ------ Total non-staff expenses....... 1,559 1,249 2,537 1,564 1,224 ------ ------ ------ ------ ------ Total noninterest expenses..... $3,150 $2,631 $5,858 $3,867 $2,785 ====== ====== ====== ====== ====== Employee compensation and benefits expense for the six months ended June 30, 2002 was $1.6 million, an increase of $209,000 or 15% compared with $1.4 million for the same period in 2001. The increase was due primarily to additional staff. The number of full-time equivalent employees was 51 at June 30, 2002 compared with 43 at June 30, 2001, an increase of 19%. Employee compensation and benefits expense for the years ended December 31, 2001, 2000 and 1999 was $3.3 million, $2.3 million and $1.6 million, respectively. The $1.0 million increase for the year ended December 31, 2001 results from additional staffing related to the growth in loans and deposits and the new locations, and an increase in incentive compensation of $235,000 compared with incentive compensation in 2000. Income Taxes Federal income tax is reported as income tax expense and is influenced by the amount of taxable income, the amount of tax-exempt income, the amount of nondeductible interest expense and the amount of other non-deductible expense. The effective tax rates in 2001, 2000 and 1999 were 31%, 28% and 26%, respectively. 62 Additionally, the State of Texas imposes a Texas franchise tax. Taxable income for the income tax component of the Texas franchise tax is the federal pre-tax income, plus certain officers' salaries, less interest income from federal securities. Total franchise tax expense was $8,398 in 2001, $26,131 in 2000 and $20,639 in 1999. Such expense was included as a part of other noninterest expense. Impact of Inflation The effects of inflation on the local economy and on Bank of Tanglewood's operating results have been relatively modest for the past several years. Since substantially all of Bank of Tanglewood's assets and liabilities are monetary in nature, such as cash, securities, loans and deposits, their values are less sensitive to the effects of inflation than to changing interest rates, which do not necessarily change in accordance with inflation rates. Bank of Tanglewood tries to control the impact of interest rate fluctuations by managing the relationship between its interest rate sensitive assets and liabilities. See "-- Financial Condition -- Interest Rate Sensitivity and Liquidity" on page 73. Financial Condition Loan Portfolio Bank of Tanglewood provides a broad range of commercial, real estate and consumer loan products to small and medium-sized businesses and individuals. Total loans were $134.0 million at June 30, 2002, an increase of $15.0 million or 13% from $119.0 million at December 31, 2001. Loan growth occurred primarily in commercial loans and real estate loans. Loans comprised 62% of total earning assets at June 30, 2002 compared with 51% at December 31, 2001. Total loans increased by $36.8 million or approximately 45% to $119.0 million at December 31, 2001 from $82.2 million at December 31, 2000. The increase was primarily due to active business development efforts and the addition of business development officers. In 2000, total loans increased by $19.0 million to $82.2 million at December 31, 2000 from $63.2 million at December 31, 1999. Total loans were $63.2 million, $38.0 million and $24.8 million at December 31, 1999, 1998 and 1997, respectively, resulting in increases of $25.2 million, $13.2 million and $22.1 million for each of the respective period end. The following table summarizes the loan portfolio of Bank of Tanglewood by type of loan at the periods indicated: June 30, 2002 December 31, 2001 December 31, 2000 --------------- --------------- ---------------- Amount Percent Amount Percent Amount Percent -------- ------- -------- ------- ------- ------- (Dollars in thousands) Commercial and industrial............ $ 32,343 24% $ 26,716 22% $17,883 22% Real estate: Construction and land development. 20,888 16 23,322 20 13,935 17 1-4 family residential............ 36,066 27 31,920 27 23,337 28 Commercial mortgages.............. 29,052 22 19,842 17 11,641 14 Consumer/Other.................... 15,661 11 17,189 14 15,411 19 -------- --- -------- --- ------- --- Total loans................... $134,010 100% $118,989 100% $82,207 100% ======== === ======== === ======= === December 31, 1999 December 31, 1998 December 31, 1997 --------------- --------------- ---------------- Amount Percent Amount Percent Amount Percent -------- ------- -------- ------- ------- ------- (Dollars in thousands) Commercial and industrial............ $ 14,245 22% $ 8,474 22% $ 9,335 38% Real estate: Construction and land development. 9,723 15 4,806 13 3,087 12 1-4 family residential............ 15,650 25 9,067 24 5,131 21 Commercial mortgages.............. 12,390 20 9,261 24 3,012 12 Consumer/Other.................... 11,169 18 6,394 17 4,220 17 -------- --- -------- --- ------- --- Total loans................... $ 63,177 100% $ 38,002 100% $24,785 100% ======== === ======== === ======= === 63 The primary lending focus of Bank of Tanglewood is to small and medium-sized businesses. Bank of Tanglewood offers business loans, commercial real estate loans, equipment loans, working capital loans, term loans, revolving lines of credit and letters of credit. Commercial Bank of Tanglewood's commercial loans are primarily made within its market area and are underwritten on the basis of the borrower's ability to service such debt from income. As a general practice, Bank of Tanglewood takes as collateral a lien on any available real estate, equipment, or other assets obtained or owned by the borrower and obtains a personal guaranty of the principals or owners of the borrower. In general, commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans and, therefore, usually yield a higher return. The increased risk derives from the expectation that commercial loans generally will be serviced principally from the business' operations, and those operations may not be successful. Additional risk for commercial loans is due to the type of collateral securing these loans. As a result of these additional complexities, variables and risks, commercial loans require more thorough underwriting and servicing than other types of loans. In addition to commercial loans secured by real estate, Bank of Tanglewood makes commercial mortgage loans to finance the purchase of real property, which generally consists of real estate with completed structures. Commercial mortgage lending typically involves higher loan principal amounts and the repayment of loans is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. As a general practice, Bank of Tanglewood requires its commercial mortgage loans to be secured by well-managed income producing property with adequate margins and to be guaranteed by responsible parties. Bank of Tanglewood's commercial mortgage loans are generally secured by first liens on real estate, have fixed and floating interest rates and amortize over periods up to 20 years with balloon payments due at the end of one to five years. In underwriting commercial mortgage loans, consideration is given to the property's operating history, future operating projections, current and projected occupancy, location and physical condition. The underwriting analysis also includes credit checks, appraisals and a review of the financial condition of the borrower(s) and guarantor(s). Construction Bank of Tanglewood makes loans to finance the construction of both nonresidential and residential properties. Construction loans generally are secured by first liens on real estate. Bank of Tanglewood conducts periodic inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of a project under construction. However, Bank of Tanglewood obtains third party appraisals to determine the future market value of the project prior to making the loan. Construction lending often involves the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project. Bank of Tanglewood obtains the personal guaranty of the principals of the borrower. If Bank of Tanglewood is forced to foreclose on a project prior to completion, in order to obtain maximum value of the collateral, it may be required to fund additional amounts to complete a project and may have to hold the property for an indeterminate period of time. Bank of Tanglewood has underwriting guidelines similar to those described above designed to identify what it believes to be acceptable levels of risks in construction lending. 1-4 Family Residential Bank of Tanglewood offers a variety of mortgage loan products which generally are amortized over periods up to 30 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more than 80% of the lower of cost or appraised value. Bank of Tanglewood requires mortgage title insurance and hazard insurance in the amount of the loan. As of June 30, 2002, Bank of Tanglewood's one to four family real estate loan portfolio was $36.1 million. Of this amount, $8.8 million is repriceable in one year or less and an additional $21.2 million is repriceable from one year to five years. These high percentages in short-term real estate loans reflects Bank of Tanglewood's commitment to reducing interest rate risk. 64 Consumer Bank of Tanglewood also provides a wide variety of consumer loans including motor vehicle, watercraft, education loans, personal loans (collateralized and uncollateralized) and deposit account collateralized loans. The terms of these loans typically range from 12 to 72 months and vary based upon the nature of collateral and size of loan. As of June 30, 2002, Bank of Tanglewood had no indirect consumer loans, indicating a preference to maintain personal banking relationships and strict underwriting standards. Consumer loans entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciating assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections are dependent on the borrower's continuing financial stability, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws may limit the amount which can be recovered on such loans. Lending officers are assigned various levels of loan approval authority based upon their respective levels of experience and expertise. Tanglewood's strategy for approving or disapproving loans is to follow conservative loan policies and underwriting practices which include: . granting loans on a sound and collectible basis; . investing funds properly for the benefit of shareholders and the protection of depositors; . serving the legitimate needs of the community and Bank of Tanglewood's general market area while obtaining a balance between maximum yield and minimum risk; . ensuring that primary and secondary sources of repayment are adequate in relation to the amount of the loan; . developing and maintaining adequate diversification of the loan portfolio as a whole and of the loans within each category; and . ensuring that each loan is properly documented and, if appropriate, insurance coverage is adequate. Bank of Tanglewood's loan review and compliance personnel interact daily with commercial and consumer lenders to identify potential underwriting or technical exception variances. In addition, Bank of Tanglewood has placed increased emphasis on the early identification of problem loans to aggressively seek resolution of the situations and thereby keep loan losses at a minimum. Management believes that this strict adherence to conservative loan policy guidelines has contributed to Bank of Tanglewood's below average level of loan losses compared to its industry peer group over the past few years. The contractual maturity ranges of the commercial and industrial and construction and land development loan portfolio and the amount of such loans with predetermined interest rates in each maturity range as of December 31, 2001, are summarized in the following table: December 31, 2001 -------------------------------------- After One One Year Through After or Less Five Years Five Years Total -------- ---------- ---------- ------- (Dollars in thousands) Commercial and industrial................ $21,988 $4,728 $ -- $26,716 Construction and land development........ 16,718 4,416 2,188 23,322 ------- ------ ------ ------- Total.................................... $38,706 $9,144 $2,188 $50,038 ======= ====== ====== ======= Loans with a pre-determined interest rate $ 1,066 $2,404 $ 875 $ 4,345 Loans with a floating interest rate...... 37,640 6,740 1,313 45,693 ------- ------ ------ ------- Total.................................... $38,706 $9,144 $2,188 $50,038 ======= ====== ====== ======= 65 Nonperforming Assets Bank of Tanglewood has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. Bank of Tanglewood has established underwriting guidelines to be followed by its officers and also monitors its delinquency levels for any negative or adverse trends. There can be no assurance, however, that Bank of Tanglewood's loan portfolio will not become subject to increasing pressures from deteriorating borrower credit due to general economic conditions. Nonperforming assets were $948,000 at June 30, 2002 compared with $814,000 at December 31, 2001, reflecting continued strong asset quality. The ratio of nonperforming assets to total loans and other real estate was 0.70% at June 30, 2002 and 0.68% at December 31, 2001. There were no nonperforming assets at December 31, 2000. Bank of Tanglewood generally places a loan on nonaccrual status and ceases to accrue interest when loan payment performance is deemed unsatisfactory. Loans where the interest payments jeopardize the collection of principal are placed on nonaccrual status, unless the loan is both well-secured and in the process of collection. Cash payments received while a loan is classified as nonaccrual are recorded as a reduction of principal as long as doubt exists as to collection. Bank of Tanglewood is sometimes required to revise a loan's interest rate or repayment terms in a troubled debt restructuring, however, Bank of Tanglewood had no restructured loans at June 30, 2002 and December 31, 2001. In addition to an internal loan review, Bank of Tanglewood retains The Bankers Advantage Group for a semi-annual external review to evaluate the loan portfolio. Bank of Tanglewood maintains current appraisals on loans secured by real estate, particularly those categorized as nonperforming loans and potential problem loans. In instances where updated appraisals reflect reduced collateral values, an evaluation of the borrower's overall financial condition is made to determine the need, if any, for possible write downs or appropriate additions to the allowance for loan losses. Bank of Tanglewood records other real estate at fair value at the time of acquisition, less estimated costs to sell. Bank of Tanglewood has adopted Statement of Financial Accounting Standards ("SFAS") No. 114, Accounting by Creditors for Impairment of a Loan, as amended by SFAS No. 118, Accounting for Creditors for Impairment of a Loan- Income Recognition and Disclosures. Under SFAS No. 114, as amended, a loan is considered impaired based on current information and events, if it is probable that Bank of Tanglewood will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. The measurement of impaired loans is based on the present value of expected future cash flows discounted at the loan's effective interest rate or the loan's observable market price or based on the fair value of the collateral if the loan is collateral-dependent. The implementation of SFAS No. 114 did not have a material adverse effect on Bank of Tanglewood's financial statements. The following table presents information regarding nonperforming assets as of the dates indicated: June 30, December 31, -------- ----------- 2002 2001 2000 -------- ----- ---- (Dollars in thousands) Nonaccrual loans......................................... $ -- $ -- $ -- Accruing loans past due 90 days or more.................. -- 814 -- Restructured loans....................................... -- -- -- Other real estate........................................ 948 -- -- ----- ----- ---- Total nonperforming assets........................ $ 948 $ 814 $ -- ===== ===== ==== Nonperforming assets to total loans and other real estate 0.70% 0.68% N/A% ===== ===== ==== 66 December 31, ------------------- 1999 1998 1997 ----- ----- ----- (Dollars in thousands) Nonaccrual loans......................................... $ -- $ -- $ -- Accruing loans past due 90 days or more.................. -- -- -- Restructured loans....................................... -- -- -- Other real estate........................................ -- -- -- ----- ----- ----- Total nonperforming assets........................ $ -- $ -- $ -- ===== ===== ===== Nonperforming assets to total loans and other real estate N/A % N/A % N/A % ===== ===== ===== Allowance for Loan Losses The allowance for loan losses is a reserve established through charges to earnings in the form of a provision for loan losses. Management has established an allowance for loan losses which it believes is adequate based on the quality of Bank of Tanglewood's loan portfolio. Based on an evaluation of the loan portfolio, management presents a quarterly review of the allowance for loan losses to Bank of Tanglewood's board of directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. In making its evaluation, management considers the diversification by collateral type of Bank of Tanglewood's commercial loan portfolio, the effect of changes in the local real estate market on collateral values, the results of recent regulatory examinations, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers, the amount of charge-offs for the period, the amount of nonperforming loans and related collateral security and the evaluation of its loan portfolio by the semi-annual external loan review conducted by The Bankers Advantage Group. Charge-offs occur when loans are deemed to be uncollectible. In originating loans, Bank of Tanglewood recognizes that credit losses will be experienced and the risk of loss will vary with, among other things, general economic conditions, the type of loan being made, the creditworthiness of the borrower over the term of the loan and, in the case of a collateralized loan, the quality of the collateral for such loan. Bank of Tanglewood follows an internal loan review program to evaluate the credit risk in the loan portfolio. Through the loan review process, Bank of Tanglewood maintains an internally classified loan list which, along with the delinquency list of loans, helps management assess the overall quality of the loan portfolio and the adequacy of the allowance for loan losses. Loans internally classified as "substandard" or in the more severe categories of "doubtful" or "loss" are those loans that at a minimum have clear and defined weaknesses such as a highly-leveraged position, unfavorable financial ratios, uncertain repayment sources or poor financial condition, which may jeopardize recoverability of the debt. At June 30, 2002, Bank of Tanglewood had $20,621 of such loans compared with $1.2 million at June 30, 2001, a 98% decrease. The decrease reflects the foreclosure of collateral securing a real estate loan in June 2002 thereby transferring the asset from the loan category to the other real estate category. In addition to the internally classified loan list and delinquency list of loans, Bank of Tanglewood maintains a separate "watch list" which further aids Bank of Tanglewood in monitoring loan portfolios. Watch list loans show warning elements where the present status portrays one or more deficiencies that require attention in the short term or where pertinent ratios of the loan account have weakened to a point where more frequent monitoring is warranted. These loans do not have all of the characteristics of a classified loan (substandard or doubtful) but do show weakened elements as compared with those of a satisfactory credit. Bank of Tanglewood reviews these loans to assist in assessing the adequacy of the allowance for loan losses. At June 30, 2002, Bank of Tanglewood had $1.1 million of "watch list" loans. In determining the allowance, Bank of Tanglewood segments the loan portfolio into risk grades ranging from 1 to 7, with grade 1 having the least amount of risk. Loans are individually analyzed and assigned risk 67 grades based on their past due status, nonaccrual status or any other impaired characteristic of the loan. Since inception in December 1996, Bank of Tanglewood has had aggregate net charge-offs of $11,815. Because Bank of Tanglewood has little historical loss data from which to assess the adequacy of its allowance, the bank attempts to maintain an allowance of at least 1.0% of total loans. Bank of Tanglewood then charges to operations a provision for loan losses to maintain the allowance for loan losses at an adequate level to absorb losses inherent in the loan portfolio determined by the foregoing methodology. Management actively monitors Bank of Tanglewood's asset quality and provides specific loss allowances when necessary. Loans are charged-off against the allowance for loan losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the allowance for loan losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the initial determinations. As of June 30, 2002, the allowance for loan losses amounted to $1.4 million or 1.02% of total loans. For the year ended December 31, 2001, there were no net loan charge-offs, compared with $4,792 in net loan charge-offs or 0.005% of average loans for the year ended December 31, 2000. During 2001, Bank of Tanglewood recorded a provision for loan losses of $271,900 compared with $315,600 for 2000. The decrease in the provision for 2001 is primarily the result of the perceived quality of the loan portfolio. At December 31, 2001, the allowance for loan losses totaled $1.2 million, or 1.02% of total loans. At December 31, 2000, the allowance for loan losses totaled $943,000 or 1.15% of total loans. The allowance for loan losses totaled $632,000, $187,000 and $97,000 at December 31, 1999, 1998 and 1997, respectively. At December 31, 1999, 1998 and 1997 the allowance for loan losses as a percentage of total loans was 1.00%, 0.49% an 0.39%, respectively. The following table presents, for the periods indicated, an analysis of the allowance for loan losses and other related data: Six Months Ended June 30, Years Ended December 31, ---------- -------------------------------------------- 2002 2001 2000 1999 1998 1997 ---------- -------- ------- ------- ------- ------- (Dollars in thousands) Average loans outstanding................. $129,778 $ 98,449 $72,616 $50,153 $30,768 $11,239 ======== ======== ======= ======= ======= ======= Gross loans outstanding at end of period.. $134,010 $118,989 $82,207 $63,177 $38,002 $24,785 ======== ======== ======= ======= ======= ======= Allowance for loan losses at beginning of period.................................. $ 1,215 $ 943 $ 632 $ 187 $ 97 $ 7 Provision for loan losses................. 155 272 316 445 90 90 Charge-offs: Commercial and industrial.............. -- -- -- -- -- -- Real estate............................ -- -- -- -- -- -- Consumer............................... 7 1 5 -- -- -- Other.................................. -- -- -- -- -- -- Recoveries: Commercial and industrial.............. -- -- -- -- -- -- Real estate............................ -- -- -- -- -- -- Consumer............................... -- 1 -- -- -- -- Other.................................. -- -- -- -- -- -- -------- -------- ------- ------- ------- ------- Net loan charge-offs...................... 7 -- 5 -- -- -- -------- -------- ------- ------- ------- ------- Allowance for loan losses at end of period $ 1,363 $ 1,215 $ 943 $ 632 $ 187 $ 97 ======== ======== ======= ======= ======= ======= Ratio of allowance to end of period loans. 1.02% 1.02% 1.15% 1.00% 0.49% 0.39% Ratio of net loan charge-offs to average loans................................... 0.005% N/A 0.007% N/A N/A N/A Ratio of allowance to end of period nonperforming loans.....................

There can be no assurance, however, that Bank of Tanglewood will not sustain losses in future periods, which could be substantial in relation to the size of the allowance for loan losses at June 30, 2002. Securities Bank of Tanglewood uses its securities portfolio to ensure liquidity for cash requirements, to manage interest rate risk, to provide a source of income, to ensure collateral is available for municipal pledging requirements and to manage asset quality. Securities totaled $80.3 million at June 30, 2002, a decline of $35.0 million from $115.3 million at December 31, 2001. The decline was primarily due to a sale of $11.6 million of securities prompted by a decrease in total deposits, and security principal reductions allowed in order to fund loan growth. At June 30, 2002, securities represented 34% of total assets compared with 46% of total assets at 69 December 31, 2001. The yield on average securities for the six months ended June 30, 2002 was 6.26% compared with 6.68% for the same period in 2001. The average life of the securities portfolio at June 30, 2002 was approximately 4 years and 9 months. At December 31, 2001, the carrying value of investment securities totaled $115.3 million, an increase of $56.9 million from $58.4 million at December 31, 2000. The increase was primarily attributable to an increase in deposits. At December 31, 2001, investment securities represented 46% of total assets compared with 38% of total assets at December 31, 2000. At December 31, 2000, the carrying value of investment securities totaled $58.4 million, an increase of $10.0 million from $48.4 million at December 31, 1999.

At each reporting date, the appropriateness of the classification is reassessed. Investments in debt securities are classified as held-to-maturity and measured at amortized cost in the financial statements only if management has the positive intent and ability to hold those securities to maturity. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and measured at fair value in the financial statements with unrealized gains and losses included in earnings. Investments not classified as either held-to-maturity or trading are classified as available-for-sale and measured at fair value in the financial statements with unrealized gains and losses reported, net of tax, in a separate component of shareholders' equity until realized. Deposits Bank of Tanglewood offers a variety of deposit accounts having a wide range of interest rates and terms. Bank of Tanglewood's deposit accounts consist of demand, savings, money market and time accounts. Bank of Tanglewood relies primarily on competitive pricing policies and customer service to attract and retain these deposits. Bank of Tanglewood does not have or accept any brokered deposits. 71 At June 30, 2002, demand, money market and savings deposits accounted for approximately 76% of total deposits, while certificates of deposit made up 24% of total deposits. Noninterest-bearing demand deposits totaled $44.3 million or 22% of total deposits at June 30, 2002, compared with $47.6 million or 21% of total deposits at December 31, 2001. The average cost of deposits, including noninterest-bearing demand deposits, was 1.63% for the six months ended June 30, 2002 compared with 3.56% for the same period in 2001. The decrease in the average cost of deposits was primarily due to the falling rate environment of 2001. At June 30, 2002, total deposits were $204.7 million compared with $222.0 million at December 31, 2001, a decrease of $17.3 million or 8%. This decrease is primarily attributable to the loss of one account of approximately $6 million and the continuing low level of interest rates prompting depositors to seek alternatives. At December 31, 2001, total deposits increased to $222.0 million from $139.0 million at December 31, 2000, an increase of $83.0 million or 60%. At December 31, 2000, total deposits increased to $139.0 million from $104.9 million at December 31, 1999, an increase of $34.1 million or 33%. These increases are primarily attributable to deposits of new customers. Bank of Tanglewood's ratio of average noninterest-bearing demand deposits to average total deposits for years ended December 31, 2001, 2000 and 1999 was 19%, 18% and 17%, respectively.

Bank of Tanglewood has established a $3 million unsecured overnight line of credit with Bank One, Texas, N.A. In addition, Bank of Tanglewood has the ability to borrow funds based on its relationship with the Federal Home Loan Bank of Dallas. Interest Rate Sensitivity and Liquidity Bank of Tanglewood's asset liability and funds management policy provides management with the necessary guidelines for effective funds management, and Bank of Tanglewood has established a measurement system for monitoring its net interest rate sensitivity position. Bank of Tanglewood manages its sensitivity position within established guidelines. Interest rate risk is managed by the Asset Liability Committee ("ALCO"), which is composed of senior officers of Bank of Tanglewood, in accordance with policies approved by Bank of Tanglewood's board of directors. The ALCO formulates strategies based on appropriate levels in interest rate risk. In determining the appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital based on the current outlook on interest rates, potential changes in interest rates, regional economies, liquidity, business strategies and other factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate changes, the book and market values of assets and liabilities, unrealized gains and losses, purchase and sale activity, commitments to originate loans, and the maturities of investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow flexibility, maturities of deposits and consumer and commercial deposit activity. Management uses two methodologies to manage interest rate risk: (i) an analysis of relationships between interest-earning assets and interest-bearing liabilities; and (ii) an interest rate 73 shock simulation model. Bank of Tanglewood has traditionally managed its business to control its overall exposure to changes in interest rates. To effectively measure and manage interest rate risk, Bank of Tanglewood uses an interest rate simulation model to determine the impact on net interest income under various interest rate scenarios, balance sheet trends and strategies. From these simulations, interest rate risk is quantified and appropriate strategies are developed and implemented. Additionally, duration and market value sensitivity measures are utilized when they provide added value to the overall interest rate risk management process. The overall interest rate risk position and strategies are reviewed by Bank of Tanglewood's Board of Directors on an ongoing basis. Bank of Tanglewood manages its exposure to interest rates by structuring its balance sheet in the ordinary course of business. Bank of Tanglewood does not currently enter into instruments such as leveraged derivatives, structured notes, interest rate swaps, caps, floors, financial options, financial futures contracts or forward delivery contracts for the purpose of reducing interest rate risk. An interest rate sensitive asset or liability is one that, within a defined time period, either matures or experiences an interest rate change in line with general market interest rates. The management of interest rate risk is performed by analyzing the maturity and repricing relationships between interest-earning assets and interest-bearing liabilities at specific points in time ("GAP") and by analyzing the effects of interest rate changes on net interest income over specific periods of time by projecting the performance of the mix of assets and liabilities in varied interest rate environments. Interest rate sensitivity reflects the potential effect on net interest income of a movement in interest rates. A bank is considered to be asset sensitive, or having a positive GAP, when the amount of its interest-earning assets maturing or repricing within a given period exceeds the amount of its interest-bearing liabilities also maturing or repricing within that time period. Conversely, a bank is considered to be liability sensitive, or having a negative GAP, when the amount of its interest-bearing liabilities maturing or repricing within a given period exceeds the amount of its interest-earning assets also maturing or repricing within that time period. During a period of rising interest rates, a negative GAP would tend to affect net interest income adversely, while a positive GAP would tend to result in an increase in net interest income. During a period of falling interest rates, a negative GAP would tend to result in an increase in net interest income, while a positive GAP would tend to affect net interest income adversely. However, it is management's intent to achieve a proper balance so that incorrect rate forecasts should not have a significant impact on earnings. 74 The following table sets forth an interest rate sensitivity analysis for Bank of Tanglewood at June 30, 2002: Volumes Subject to Repricing Within ------------------------------------------------- Greater 0-90 91-365 1-3 than Days Days Years 3 Years Total -------- -------- ------- ------- -------- (Dollars in thousands) Interest-earning assets: Securities(1)................................... $ 10,582 $ 16,989 $32,114 $20,425 $ 80,110 Loans........................................... 82,912 5,823 12,469 32,806 134,010 Federal funds sold.............................. -- -- -- -- -- Due from banks.................................. 3,914 -- -- -- 3,914 -------- -------- ------- ------- -------- Total interest-earning assets................... $ 97,408 $ 22,812 $44,583 $53,231 $218,034 ======== ======== ======= ======= ======== Interest-bearing liabilities: NOW, money market and savings deposits.......... $110,580 $ -- $ -- $ -- $110,580 Certificates of deposit and other time deposits. 13,703 26,971 8,997 186 49,857 Borrowed funds.................................. 11,678 -- -- -- 11,678 -------- -------- ------- ------- -------- Total interest-bearing liabilities.............. $135,961 $ 26,971 $ 8,997 $ 186 $172,115 ======== ======== ======= ======= ======== Period GAP......................................... $(38,553) $ (4,159) $35,586 $53,045 Cumulative GAP..................................... $(38,553) $(42,712) $(7,126) $45,919 Period GAP to total assets.........................

Bank of Tanglewood's one-year cumulative GAP position at June 30, 2002, was negative $42.7 million or 18.2% of assets. This is a one-day position that is continually changing and is not indicative of Bank of Tanglewood's position at any other time. While the GAP position is a useful tool in measuring interest rate risk and contributes toward effective asset and liability management, it is difficult to predict the effect of changing interest rates solely on that measure, without accounting for alterations in the maturity or repricing characteristics of the balance sheet that occur during changes in market interest rates. For example, the GAP position reflects only the prepayment assumptions pertaining to the current rate environment. Assets tend to prepay more rapidly during periods of declining interest rates than during periods of rising interest rates. Because of this and other risk factors not contemplated by the GAP position, an institution could have a matched GAP position in the current rate environment and still have its net interest income exposed to increased rate risk. The ALCO Committee reviews Bank of Tanglewood's interest rate risk position on a quarterly basis. Bank of Tanglewood's liquidity is maintained in the form of readily marketable investment securities, demand deposits with commercial banks, vault cash and federal funds sold. While the minimum liquidity requirement for banks is determined by federal bank regulatory agencies as a percentage of deposit liabilities, the bank's management monitors liquidity requirements as warranted by interest rate trends, changes in the economy and the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits. In addition to the liquidity provided by the foregoing, Bank of Tanglewood has correspondent relationships with other banks in order to sell loans or purchase overnight funds should additional liquidity be needed. In addition, Bank of Tanglewood has the ability to borrow funds based on its relationship with the Federal Home Loan Bank of Dallas. Capital Resources Capital management consists of providing equity to support both current and future operations. Bank of Tanglewood is subject to capital adequacy requirements imposed by the OCC. The OCC has 75 adopted risk-based capital requirements for assessing bank capital adequacy. These standards define capital and establish minimum capital requirements in relation to assets and off-balance sheet exposure, adjusted for credit risk. The risk-based capital standards currently in effect are designed to make regulatory capital requirements more sensitive to differences in risk profiles among banks, to account for off-balance sheet exposure and to minimize disincentives for holding liquid assets. Assets and off-balance sheet items are assigned to broad risk categories, each with appropriate relative risk weights. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items. The risk-based capital standards issued by the OCC require all national banks to have "Tier 1 risk-based capital" of at least 4.0% and "total risk-based capital" (Tier 1 and Tier 2) of at least 8.0% of total risk-adjusted assets. "Tier 1 capital" generally includes common shareholders' equity and non-cumulative perpetual preferred stock together with related surpluses, retained earnings, and minority interests in the equity capital accounts of consolidated subsidiaries, less deductions for net unrealized losses on available-for-sale equity securities. "Tier 2 capital" includes the bank's allowance for loan and lease losses (but only up to a maximum of 1.25% of risk-weighted assets); cumulative perpetual preferred stock, long-term preferred stock, convertible preferred stock and any related surplus; hybrid capital instruments, including mandatory convertible debt securities; and term subordinated debt and intermediate-term preferred stock (original maturity of five years or more) and any related surplus. The sum of Tier 1 capital and Tier 2 capital is "total risk-based capital." The foregoing summary is qualified in its entirety by reference to the applicable regulations. The OCC has also adopted guidelines which supplement the risk-based capital guidelines with a minimum ratio of Tier 1 capital to total assets ("leverage ratio") of 3.0% for institutions that are highly rated (composite 1 under applicable federal guidelines), and that are not experiencing or anticipating significant growth. Other banking organizations are required to maintain a leverage ratio of at least 4.0%. Pursuant to the Federal Deposit Insurance Corporation Improvement Act ("FDICIA"), each federal banking agency revised its risk-based capital standards to ensure that those standards take adequate account of interest rate risk, concentration of credit risk and the risks of nontraditional activities, as well as reflect the actual performance and expected risk of loss on multifamily mortgages. Also pursuant to FDICIA, the OCC has promulgated regulations setting the levels at which an insured institution such as the bank would be considered "well capitalized," "adequately capitalized," "undercapitalized," "significantly undercapitalized" and "critically undercapitalized." Bank of Tanglewood is classified "well capitalized" for purposes of the OCC prompt corrective action regulations. Total shareholders' equity as of June 30, 2002 was $17.2 million, an increase of $1.5 million or 10% compared with shareholders' equity of $15.7 million at December 31, 2001. The increase was primarily due to net earnings for the period of $1.6 million. The following table provides a comparison of Bank of Tanglewood's leverage and risk-weighted capital ratios as of June 30, 2002 and December 31, 2001 to the minimum and well-capitalized regulatory standards: Minimum Required for To be Well Capitalized Capital Adequacy Under Prompt Corrective Actual Ratio at Actual Ratio at Purposes Action Provisions June 30, 2002 December 31, 2001 ---------------- ----------------------- --------------- ----------------- Leverage ratio................. 4.00%(1) 5.00% 7.24% 6.40% Tier 1 risk-based capital ratio 4.00 6.00 12.47 11.22 Total risk-based capital ratio. 8.00 10.00 13.47 12.11 -------- (1) The OCC may require Bank of Tanglewood to maintain a leverage ratio above the required minimum. 76 BUSINESS OF BANK OF TANGLEWOOD General Bank of Tanglewood is a national banking association which opened for business in December 1996. Bank of Tanglewood offers a diversified range of commercial banking services for business, industry, public and governmental organizations and individuals located principally in the Houston and Harris County, Texas areas. Bank of Tanglewood services include the usual deposit functions of commercial banks, safe deposit facilities, commercial and personal banking services, and the making of commercial and industrial, interim construction, consumer and real estate loans. When the borrowing needs of a customer exceed Bank of Tanglewood's lending limit, it participates with other banks in making the loan. Similarly, Bank of Tanglewood provides other services for its customers through Bank of Tanglewood's correspondent and other relationships with other financial institutions. Bank of Tanglewood's strategy is to concentrate on locally owned small to medium-sized businesses and individual banking needs of the market areas it serves. Bank of Tanglewood promotes the bank as "the community bank" of the Tanglewood, West University and Memorial areas of Houston, serving all aspects of the market. Bank of Tanglewood's market area is either in or contiguous to the Tanglewood, West University and Memorial residential areas, since many residents of the area either own or manage businesses in Houston. This provides the opportunity to offer banking services to businesses not in the immediate area but where its ownership or management resides. Additionally, the area's steady growth of residential developments provides us with access to those potential customers. Bank of Tanglewood also has a wholly-owned Texas corporation subsidiary known as Tanglewood Financial Services Incorporated to serve Bank of Tanglewood customers' and others' estate planning, insurance and investment needs. It offers various financial products such as stocks, bonds, mutual funds, annuities and various forms of insurance. Employees As of June 30, 2002, Bank of Tanglewood had 51 full-time equivalent employees, 16 of whom were officers. Bank of Tanglewood provides medical insurance and other benefits to our full-time employees. Bank of Tanglewood employees are not represented by any collective bargaining group. Bank of Tanglewood considers our relations with our employees to be satisfactory. Property Bank of Tanglewood main office facilities are located at 500 Chimney Rock Road in Houston, Texas. Bank of Tanglewood leases a two-story office building of approximately 9,000 square feet which was constructed for the bank at that location. Additionally, Bank of Tanglewood has a five-lane drive-in facility attached to the building. The West University office facility is located at 5500 Kirby Drive, Houston, Texas. The building is owned by Bank of Tanglewood and has approximately 5,200 square feet and an attached five-lane motor bank facility. It is situated on two adjoining parcels of land, one that is owned by Bank of Tanglewood and one that is leased under a long-term land lease. Bank of Tanglewood's Memorial facility is in the Town and Country Village shopping center. Bank of Tanglewood has a long term ground lease on the location and owns the newly constructed building and attached motor bank. 77 Legal Proceedings Bank of Tanglewood from time to time is a party to or otherwise involved in legal proceedings arising in the normal course of business. Management does not believe that there is any pending or threatened proceeding against Bank of Tanglewood which, if determined adversely, would have a material effect on Bank of Tanglewood's business, financial condition or results of operation. Competition The banking business is highly competitive and Bank of Tanglewood's profitability depends primarily on its ability to compete in its markets. Bank of Tanglewood competes with other commercial banks, savings banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking firms, asset-based non-bank lenders and certain other nonfinancial entities, including retail stores which may maintain their own credit programs and certain governmental organizations which may offer more favorable financing than Bank of Tanglewood can. Many of Bank of Tanglewood's competitors have greater financial strength, marketing capability and name recognition than Bank of Tanglewood does, and operate on a statewide, regional or nationwide basis. These institutions are also likely to have legal loan limits substantially in excess of those that are maintained by Bank of Tanglewood. In addition, recent developments in technology and mass marketing have permitted larger companies to market loans and other products and services more aggressively to Bank of Tanglewood small business customers. Such advantages may enable Bank of Tanglewood competitors to realize greater economies of scale and operating efficiencies than Bank of Tanglewood can. Such institutions can perform certain functions for their customers, including trust and international banking services, which Bank of Tanglewood does not offer directly. Although Bank of Tanglewood may offer these services through correspondent banks or others in the future, the inability to provide such services directly may be a competitive disadvantage. Further, some of Bank of Tanglewood's nonbank competitors are not subject to the same extensive regulations that govern Bank of Tanglewood. Supervision and Regulation As a national bank, Bank of Tanglewood is principally supervised, examined and regulated by the Office of the Comptroller of the Currency. Because Bank of Tanglewood is a member of the Federal Reserve System and our deposits are insured by the FDIC, Bank of Tanglewood is also subject to regulation pursuant to the Federal Reserve Act and the Federal Deposit Insurance Act. The aspects of Bank of Tanglewood business which are regulated under federal law include security requirements, reserve requirements, investments, transactions with affiliates, amounts Bank of Tanglewood may lend to a single customer, business activities in which Bank of Tanglewood may engage and minimum capital requirements. Bank of Tanglewood is also subject to applicable provisions of Texas law insofar as they do not conflict with and are not preempted by federal law, including laws relating to usury, various consumer and commercial loans and the operation of branch offices. Such supervision and regulation is intended primarily for the protection of depositors, the deposit insurance funds of the FDIC and the banking system as a whole, and not for the protection of Bank of Tanglewood shareholders or creditors. The following discussion summarizes some of the laws to which Bank of Tanglewood is subject. References herein to applicable statutes and regulations are brief summaries thereof, do not purport to be complete and are qualified in their entirety by reference to such statutes and regulations. Capital Adequacy Requirements. The OCC has adopted regulations establishing minimum requirements for the capital adequacy of national banks. The OCC's regulations require national banks to have and maintain a "Tier 1 risk-based capital" ratio of at least 4.0% and a "Total risk-based capital" ratio of at least 8.0% of total risk-adjusted assets. Total risk-based capital represents the sum of Tier 1 capital and Tier 2 capital, as those terms are defined in the regulations. At June 30, 2002 Bank of Tanglewood's Tier 1 risk-based capital ratio was 12.47% and its total risk-based capital ratio was 13.47%. 78 The OCC also requires national banks to meet a minimum "leverage ratio" of Tier 1 capital to total assets of not less than 3.0% for a bank that is not anticipating or experiencing significant growth and is highly rated (i.e., has a composite rating of 1 on a scale of 1 to 5). Banks that the OCC determines are anticipating or experiencing significant growth or that are not highly rated must meet a minimum leverage ratio of 4.0%. At June 30, 2002 Bank of Tanglewood's leverage ratio was 7.24%. The OCC may establish minimum capital ratios above those set forth in the preceding paragraphs if deemed appropriate by the OCC, in its discretion, in light of the circumstances of a particular bank. Corrective Measures for Capital Deficiencies. The prompt corrective action regulations, which were promulgated to implement certain provisions of FDICIA, also effectively impose capital requirements on national banks, by subjecting banks with less capital to increasingly stringent supervisory actions. For purposes of the prompt corrective action regulations, a bank is "undercapitalized" if it has a total risk-based capital ratio of less than 8%; a Tier 1 risk-based capital ratio of less than 4%; or a leverage ratio of less than 4% (or less than 3% if the bank has received a composite rating of 1 in its most recent examination report and is not experiencing significant growth). A bank is "adequately capitalized" if it has a total risk-based capital ratio of 8% or higher; a Tier 1 risk-based capital ratio of 4% or higher; a leverage ratio of 4% or higher (3% or higher if the bank was rated a composite 1 in its most recent examination report and is not experiencing significant growth); and does not meet the criteria for a "well capitalized" bank. A bank is "well capitalized" if it has a total risk-based capital ratio of 10% or higher; a Tier 1 risk-based capital ratio of 6% or higher; a leverage ratio of 5% or higher; and is not subject to any written requirement to meet and maintain any higher capital level(s). At June 30, 2002, Bank of Tanglewood's capital ratios were within the regulatory guidelines for a "well capitalized" bank, however, there is no assurance that Bank of Tanglewood can maintain its capital ratios at any particular level. Under the provisions of FDICIA and the prompt corrective action regulations, for example, an "undercapitalized" bank is subject to a limit on the interest it may pay on deposits. Also, an undercapitalized bank cannot make any capital distribution, including paying a dividend (with some exceptions), or pay any management fee (other than compensation to an individual in his or her capacity as an officer or employee of the bank). Such a bank also must submit a capital restoration plan to the OCC for approval, restrict total asset growth and obtain regulatory approval prior to making any acquisition, opening any new branch office or engaging in any new line of business. An undercapitalized bank may also be subject to other, discretionary, regulatory actions. Additional mandatory and discretionary regulatory actions apply to "significantly undercapitalized" and "critically undercapitalized" banks. Failure of a bank to maintain the required capital could result in such bank being declared insolvent and closed. Deposit Insurance Assessments. Bank of Tanglewood's deposits are insured by the FDIC through the Bank Insurance Fund ("BIF") to the extent provided by law and we must pay assessments to the FDIC for such deposit insurance protection. The FDIC has implemented a risk-based assessment system under which FDIC-insured depository institutions pay annual premiums at rates based on their risk classification. A bank's risk classification is based on its capital levels and the level of supervisory concern the bank poses to the regulators. Institutions assigned to higher risk classifications (that is, institutions that pose a greater risk of loss to their respective deposit insurance funds) pay assessments of higher rates than institutions that pose a lower risk. A decrease in the bank's capital ratios or the occurrence of events that have an adverse effect on the bank's asset quality, management, earnings or liquidity could result in a substantial increase in deposit insurance premiums paid by the bank, which would adversely effect the bank's earnings. In addition, the FDIC can impose special assessments in certain instances. The range of assessments in the risk-based system is determined by the reserve ratio in the BIF. The current range of BIF assessments is between 0% and 0.27% of deposits because the BIF reserve ratio was greater than 1.25% when the ratios were set. Since then the BIF reserve ratio has fallen below 1.25%, creating the possibility that the FDIC will raise assessment rates the next time it revises them in November 2002. Most banks insured by the BIF, including Bank of Tanglewood, are currently not paying premiums to the FDIC. However, the Economic Growth and Regulatory Paperwork Reduction Act of 1996 requires, among other 79 things, that banks insured under the BIF pay a portion of the interest due on bonds that were issued to help shore up the ailing Federal Savings and Loan Insurance Corporation in 1987. With respect to the assessment of the bond obligations, the BIF rate is 0.0172% of deposits for the third quarter of 2002 and is adjusted quarterly to reflect changes in the assessment bases of the respective funds based on quarterly Call Report submissions. Change in Control. The Change in Bank Control Act and regulations promulgated by the OCC require that, depending on the particular circumstances, notice must be furnished to the OCC and not disapproved prior to any person or group of persons acquiring "control" of a national bank, subject to exemptions for certain transactions. Control is conclusively presumed to exist if a person acquires the power to vote, directly or indirectly, 25% or more of any class of voting securities of the bank. In addition, the term includes the power to direct the management and policies of the bank. Control is rebuttably presumed to exist if a person acquires 10% or more but less than 25% of any class of voting securities and either the bank has registered securities under Section 12 of the Securities Exchange Act of 1934, as amended, or no other person will own a greater percentage of that class of voting securities immediately after the transactions. The regulations provide a procedure for challenge of the rebuttable control presumption. Bank Holding Company Regulation. Under the Bank Holding Company Act of 1956, as amended, and regulations promulgated thereunder by the Federal Reserve, no company may acquire control of a bank without prior approval of the Federal Reserve. The ownership, control or power to vote 25% or more of any class of voting securities is presumed to be a controlling interest under the Bank Holding Company Act and, depending on the circumstances, control may exist below this level. Any company acquiring such control would become a bank holding company under such act and would be subject to restrictions on its operations as well as registration, examination and regulation by the Federal Reserve. Examinations. The OCC periodically examines and evaluates national banks. These examinations review areas such as capital adequacy, reserves, loan portfolio quality and management, consumer and other compliance issues, investments and management practices. In addition to these regular exams, we are required to furnish quarterly and annual reports to the OCC. The OCC may exercise cease and desist or other supervisory powers over a national bank if its actions represent unsafe or unsound practices or violations of law. Further, any proposed addition of any individual to the Board of Directors of the bank or the employment of any individual as a senior executive officer of the bank, or the change in responsibility of such an officer, will be subject to 90 days prior written notice to the OCC if the bank is not in compliance with the applicable minimum capital requirements, is otherwise a troubled institution or the OCC determines that such prior notice is appropriate for the bank. The OCC then has the opportunity to disapprove any such appointment. Although Bank of Tanglewood is subject to extensive regulation, supervision and examination, such activities do not eliminate and may not lessen its business risk and may increase its cost of doing business. Financial Modernization. The Gramm-Leach-Bliley Act, which eliminated the barriers to affiliations among banks, securities firms, insurance companies and other financial service providers, permits banks meeting certain criteria to engage in activities that are financial in nature. The Gramm-Leach-Bliley Act defines "financial in nature" to include securities underwriting, dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and agency; merchant banking activities; and activities that the Federal Reserve has determined to be closely related to banking. As a national bank, Bank of Tanglewood may establish a financial subsidiary and engage, subject to limitations on investment, in activities that are financial in nature, other than insurance underwriting as principal, insurance company portfolio investment, real estate development, real estate investment, annuity issuance and merchant banking activities. To do so, a bank must be well capitalized, well managed and have a CRA rating of satisfactory or better. National banks with financial subsidiaries must remain well capitalized and well managed in order to continue to engage in activities that are financial in nature without regulatory actions or restrictions. These actions or restrictions could include divestiture of the financial in nature subsidiary or subsidiaries. 80 Consumer Laws and Regulations. In addition to the laws and regulations discussed herein, Bank of Tanglewood is also subject to certain consumer laws and regulations that are designed to protect consumers in transactions with banks. While the list set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act and the Fair Housing Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such customers. Bank of Tanglewood must comply with the applicable provisions of these consumer protection laws and regulations as part of its ongoing customer relations. Instability of Regulatory Structure. Various legislation, such as the Gramm-Leach-Bliley Act which expanded the powers of banking institutions and bank holding companies, and proposals to overhaul the bank regulatory system and limit the investments that a depository institution may make with insured funds, is from time to time introduced in Congress. As noted above, Bank of Tanglewood also may be subject to changes in applicable state statutes. Such legislation may change banking statutes and the environment in which Bank of Tanglewood operates in substantial and unpredictable ways. Bank of Tanglewood cannot determine the ultimate effect that the Gramm-Leach-Bliley Act will have, or the effect that any other potential legislation, if enacted, or implementing regulations with respect thereto, would have, upon our financial condition or results of operations. Similarly, proposals to change the accounting treatment applicable to banks and other depository institutions are frequently raised by the SEC, the FDIC, the IRS and other appropriate authorities, including, among others, proposals relating to fair market value accounting for certain classes of assets and liabilities. The likelihood and impact of any additional future accounting rule changes and the impact such changes might have on the bank are impossible to determine. Expanding Enforcement Authority. One of the major additional burdens imposed on the banking industry by FDICIA is the increased ability of banking regulators to monitor the activities of banks and their holding companies. In addition, the OCC, Federal Reserve and FDIC have extensive authority to police unsafe or unsound practices and violations of applicable laws and regulations by depository institutions and their holding companies. For example, the FDIC may terminate the deposit insurance of any institution which it determines has engaged in an unsafe or unsound practice. The agencies can also assess civil money penalties, issue cease and desist or removal orders, seek injunctions and publicly disclose such actions. FDICIA and other laws have expanded the agencies' authority in recent years, and the agencies have not yet fully tested the limits of their powers. Monetary Policy. The monetary policies of regulatory authorities, including the Federal Reserve, have a significant effect on the operating results of banks and bank holding companies. The Federal Reserve supervises and regulates the national supply of bank credit. Among the means available to the Federal Reserve to regulate the supply of bank credit are open market purchases and sales of U.S. government securities, changes in the discount rate on borrowings from the Federal Reserve System and changes in reserve requirements with respect to deposits. These activities are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits on a national basis, and their use may effect interest rates charged on loans or paid for deposits. Federal Reserve monetary policies and the fiscal policies of the federal government have materially effected the operating results of commercial banks in the past and are expected to continue to do so in the future. Bank of Tanglewood cannot predict the nature of future monetary and fiscal policies and the effect of such policies on its future business and earnings. Privacy Regulation. As a financial institution and in other respects, Bank of Tanglewood is subject to numerous privacy-related laws and their implementing regulations. Those laws and the regulations promulgated under their authority can limit, under certain circumstances, the extent to which Bank of Tanglewood can disclose non-public personal information that is specific to a particular person, to affiliated companies and nonaffiliated third parties. Moreover, Bank of Tanglewood is required to establish and maintain a comprehensive Information Security Program in accordance with the Interagency Guidelines Establishing Standards for 81 Safeguarding Customer Information. The program must be designed to: (1) insure the security and confidentiality of customer information; (2) protect against any anticipated threats or hazards to the security or integrity of such information; and (3) protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. The USA PATRIOT Act of 2001. The USA PATRIOT Act requires financial institutions to prohibit correspondent accounts with foreign shell banks, establish an anti-money laundering program that includes employee training and an independent audit, follow minimum standards for identifying customers and maintaining records of the identification information and make regular comparisons of customers against agency lists of suspected terrorists, their organizations and money launderers. 82 BENEFICIAL OWNERSHIP OF BANK OF TANGLEWOOD STOCK BY MANAGEMENT AND PRINCIPAL SHAREHOLDERS OF BANK OF TANGLEWOOD The following table sets forth certain information as of September 20, 2002 regarding the beneficial ownership of Bank of Tanglewood common stock by (1) each person who is known by Bank of Tanglewood to own beneficially more than 5% of the Bank of Tanglewood common stock, (2) each director and executive officer of Bank of Tanglewood and (3) all directors and executive officers as a group.

Holders of outstanding Series A Preferred Stock are entitled to dividend and/or liquidation preferences.

The Notes to Unaudited Consolidated Financial Statements are an integral part of these statements. F-4 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS Note 1. Summary of Significant Accounting and Reporting Policies Nature of Operations: The Company conducts a full-service commercial banking business from their principal office in the Tanglewood area of Houston, Texas and branches located in the West University area and in the Memorial area of Houston, Texas. In 2001, the Company raised $1,489,200 from a stock offering related to the branch opening. During 2000, the Company formed a financial subsidiary in order to serve the estate planning, insurance and investment needs of its customers. It offers various financial products such as stocks, bonds, mutual funds, annuities and various forms of insurance. Principles of Consolidation: The consolidated financial statements include the accounts of Bank of Tanglewood, N. A. ("the Bank") and its wholly-owned subsidiary, Tanglewood Financial Services Incorporated. These entities are collectively referred to as "the Company". All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans, management obtains independent appraisals for significant collateral. The Bank's loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Bank has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent on local economic conditions. While management uses available information to recognize losses on loans, further reduction in the carrying amounts of loans may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Investment Securities: Investment securities that are held for short-term resale are classified as trading securities and carried at fair value. F-5 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Debt securities are classified as held-to-maturity when the Bank has the positive intent and ability to hold the securities to maturity. Securities held to maturity are carried at amortized cost. The amortization of premium and accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity. Debt securities not classified as held-to-maturity or trading are classified as available-for-sale. Securities available for sale are carried at fair value with unrealized gains and losses reported in other comprehensive income. Realized gains (losses) on securities available for sale are included in other income (expense) and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Gains and losses on sales of securities are determined on the specific-identification method. Declines in the fair value of individual held-to-maturity and available-for-sale securities below their cost that are other than temporary result in write-downs of the individual securities to their fair value. The related write-downs are included in earnings as realized losses. Mortgage-Backed Securities: Mortgage-backed securities represent participating interests in pools of long-term first mortgage loans originated and serviced by issuers of the securities. Mortgage-backed securities are carried at unpaid principal balances, adjusted for unamortized premiums and unearned discounts. Premiums and discounts are amortized or accreted using methods approximating the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Management intends and has the ability to hold such securities to maturity. Should any be sold, the cost of securities sold is determined using the specific identification method. Loans: Loans are stated at the amount of unpaid principal, less the allowance for loan losses and net deferred loan fees and unearned discounts. Loan origination and commitment fees, as well as certain direct origination costs, are deferred and amortized as a yield adjustment over the lives of the related loans using the interest method. Amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status. Interest income generally is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on such loans are applied as a reduction of the loan principal balance. Interest income on other impaired loans is recognized only to the extent of interest payments received. Allowance for Loan Losses: The allowance for loan losses is maintained at a level which, in management's judgment, is adequate to absorb credit losses inherent in the loan portfolio. The amount of the allowance is based on management's evaluation of the collectibility of the loan portfolio, including the nature of the portfolio, credit concentrations, trends in historical loss experience, specific impaired loans, economic conditions, and other risks inherent in the portfolio. Allowances for impaired loans are generally determined based on collateral values or the present value of estimated cash flows. Although management uses available information to recognize losses on loans, because of uncertainties associated with local economic conditions, collateral values, and future cash flows on impaired loans, it is reasonably possible that a material change could occur in the allowance for loan losses in the near term. However, the amount of the change that is reasonably possible cannot be estimated. The allowance is F-6 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) increased by a provision for loan losses, which is charged to expense, and reduced by charge-offs, net of recoveries. Changes in the allowance relating to impaired loans are charged or credited to the provision for loan losses. Premises and Equipment: Land is carried at cost. Other premises and equipment are carried at cost net of accumulated depreciation. Depreciation is computed using the straight-line and declining balance methods based principally on the estimated useful lives of the assets. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations. Other Real Estate: Real estate properties acquired through or in lieu of loan foreclosure are initially recorded at the lower of the Bank's carrying amount or fair value less estimated selling cost at the date of foreclosure. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, these assets are carried at the lower of their new cost basis or fair values less estimated cost to sell. Costs of significant property improvements are capitalized, whereas costs relating to holding property are expensed. The portion of interest costs relating to development of real estate is capitalized. Valuations are periodically performed by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of its cost or fair value less estimated cost to sell. Income Taxes: Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes related primarily to differences between the basis of available-for-sale securities, allowance for loan losses, and accumulated depreciation for financial and income tax reporting. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The Company files consolidated income tax returns with its subsidiary. Mortgage Servicing Rights: Capitalized mortgage servicing assets consist of purchased and originated servicing rights. These rights are amortized in proportion to, and over the period of, the estimated future net servicing income stream of the underlying mortgage loans. Mortgage servicing rights are assessed for impairment based on the fair value of the right and any related derivative contracts. Impairment is evaluated by stratifying the mortgage servicing rights by interest rate bands. Fair value is determined considering market prices for similar assets or based on discounted cash flows using market-based prepayment estimates for similar coupons as well as incremental direct and indirect costs. The mortgage servicing operation was discontinued as of September 30, 2001, when it was sold to a third party. F-7 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Employee Benefits: Effective April 1, 1998, the Company adopted a contributory 401(k) profit sharing plan, covering substantially all employees. The Company's contributions are determined annually, at the Company's discretion. Total plan expense for the six months ended June 30, 2002 and 2001 was $32,150 and $23,550, respectively. Stock Option Plan: The Bank has a stock option plan under which 173,000 shares of common stock are reserved for issuance. Options have been granted to Bank officers and employees totaling 169,350 shares of common stock at exercise prices ranging from $10 to $35 per share. These options expire 10 years from the date of grant; options totaling 2,310 shares have been exercised to date. Deferred Compensation Plan: In November, 2001, the Board approved a deferred compensation plan for bank employees. The plan has an eight year vesting period with vesting occurring 20% annually beginning the fourth year following the date of award. Awards totaling 65,500 shares have been made at award values of $25 to $35 per share. Award shares are similar to stock option shares in nature, although they are not shares of common stock. Award values vary with changes in the market value of the common stock. No deferred compensation expense was recognized in the six months ended June 30, 2002 and 2001. Note 2. Restrictions on Cash and Due from Banks The Bank is required to maintain reserve funds in cash or on deposit with the Federal Reserve Bank. The required reserve at June 30, 2002 and 2001, was $3,251,000 and $995,000, respectively. Note 3.

Note 8. Financial Instruments with Off-Balance-Sheet Risk In the normal course of business, the Bank has outstanding commitments to extend credit and standby letters of credit, which are not included in the accompanying consolidated financial statements. The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Bank uses the same credit policies in making commitments as it does for instruments that are included in the consolidated balance sheet. Financial instruments whose contract amounts represent credit risk were as follows: 2002 2001 ----------- ----------- Commitments to extend credit $35,280,000 $33,300,000 Standby letters of credit... 1,343,087 2,619,062 ----------- ----------- $36,623,087 $35,919,062 =========== =========== Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation. Collateral held varies but may include accounts receivable, inventory, property and equipment, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank's policy for obtaining collateral, and the nature of such collateral, is essentially the same as that involved in making commitments to extend credit. The Bank has not been required to perform on any financial guarantees during the past two years. The Bank has not incurred any losses on its commitments in either 2002 or 2001. Note 9. Commitments and Contingent Liabilities The Company is obligated under various noncancelable lease agreements for premises and equipment. Net rent expense was $221,705 and $176,156 for the six months ended June 30, 2002 and 2001. The Company and the Bank are subject to claims and lawsuits which arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial statements of the Company. F-11 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Note 10. Regulatory Matters Banks are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory--and possibly additional discretionary--actions by regulators that, if undertaken, could have a direct material effect on the Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of total and Tier I capital to risk-weighted assets and of Tier I capital to average assets. Management believes, as of June 30, 2002, that the Bank meets all capital adequacy requirements to which it is subject. Banks are also subject to certain restrictions on the amount of dividends that they may declare without prior regulatory approval. As of June 30, 2002, the Bank was categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table. There are no conditions or events that management believes have changed the Bank's category. The Bank's actual capital amounts and ratios are also presented in the table.

Related Party Transactions The Bank's officers, directors and their associates, including corporations and firms of which they are officers or in which they and/or their families have an ownership interest, are customers of the Bank. Loans to officers, directors, and their associates were approximately $3,979,000 and $4,221,000 at June 30, 2002 and 2001, respectively. Note 13. Fair Value of Financial Instruments Management uses its best judgment in estimating the fair value of the Bank's financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Bank could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective year ends, and have not been reevaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each year end. The following information should not be interpreted as an estimate of the fair value of the entire Bank since a fair value calculation is only provided for a limited portion of the Bank's assets. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Bank's disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair value of the Bank's financial instruments at June 30, 2002 and 2001. Financial Instruments Valued at Carrying Value. The carrying amounts of cash and due from banks, interest-bearing deposits with banks, federal funds sold and resale agreements and loans held for sale approximate their fair value. The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other borrowed funds maturing within 90 days approximate their fair values. The carrying amounts of accrued interest approximate their fair values. Available-for-Sale and Held-to-Maturity Securities. Fair values for securities, excluding restricted equity securities, are based on available quoted market prices. If quoted market prices are unavailable, fair values are based on quoted market prices of comparable instruments. For unquoted securities for which no comparable instruments exist, the reported fair value is estimated on the basis of cost, book or appraised value as deemed appropriate by management. Available-for-sale securities are carried at their aggregate fair value. F-13 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Loans. For variable-rate commercial loans that reprice frequently (within a relatively short time frame) and have no significant change in credit risk, fair values are based on carrying values. Residential first mortgages are based on quoted market prices of similar loans. Fair values for certain junior mortgage loans, consumer installment loans, credit-card loans, and other consumer loans are estimated using discounted cash flow models. The discount rates are based on current market interest rates for similar types of loans. Fair values for commercial real estate and commercial loans that do not reprice or do not mature within relatively short time frames are estimated using discounted cash flow analyses. The discount rates used are those currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for impaired loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Deposits. The fair values for demand deposits and deposits with no defined maturity are determined to be the amount payable on demand at the reporting date. The fair values for fixed-maturity deposits are estimated using discounted cash flow models based on rates currently offered for the relevant product types with similar remaining maturities. The carrying amount, the amount at which financial instruments are reported in the balance sheet, and the estimated fair values of the Bank's financial instruments are as follows: June 30, ----------------------------------- 2002 2001 ----------------- ----------------- Carrying Fair Carrying Fair Amount Value Amount Value (000's) (000's) (000's) (000's) -------- -------- -------- -------- Financial Assets Cash and due from banks..................................... $ 14,255 $ 14,255 $ 7,349 $ 7,349 Securities available for sale............................... 12,578 12,578 50,896 50,896 Securities held to maturity................................. 67,731 68,723 36,599 36,762 Loans, net of allowance..................................... 132,647 132,647 98,230 98,230 -------- -------- -------- -------- Total financial assets.................................. 227,211 $228,203 193,074 $193,237 ======== ======== Nonfinancial Assets............................................ 7,044 6,493 -------- -------- Total assets............................................ $234,255 $199,567 ======== ======== Financial Liabilities Deposits: Noninterest bearing deposits................................ $ 44,303 $ 44,303 $ 31,285 $ 31,285 Interest bearing demand and time deposits................... 160,437 160,437 149,171 149,171 -------- -------- -------- -------- Total deposits................................................. 204,740 204,740 180,456 180,456 Federal funds purchased and securities sold under agreements to repurchase................................................... 11,678 11,678 3,649 3,649 Other borrowed funds........................................... -- -- -- -- -------- -------- -------- -------- Total financial liabilities............................. 216,418 $216,418 184,105 $184,105 ======== ======== Nonfinancial Liabilities....................................... 656 670 Stockholders' Equity........................................... 17,181 14,792 -------- -------- Total liabilities and stockholders' equity.............. $234,255 $199,567 ======== ======== Off-Balance Sheet Financial Instruments: Loan commitments............................................... $ 35,280 $ 33,300 Letters of credit.............................................. $ 1,343 $ 2,619 F-14 CORNELIUS, STEGENT & PRICE, LLP -------------------------------------------------------------------------------- 24 E.

Summary of Significant Accounting and Reporting Policies Nature of Operations: The Company conducts a full-service commercial banking business from their principal office in the Tanglewood area of Houston, Texas and branches located in the West University area and in the Memorial area of Houston, Texas. In 2001, the Company raised $1,489,200 from a stock offering related to the branch opening. During 2000, the Company formed a financial subsidiary in order to serve the estate planning, insurance and investment needs of their customers. It offers various financial products such as stocks, bonds, mutual funds, annuities and various forms of insurance. Principles of Consolidation: The consolidated financial statements include the accounts of Bank of Tanglewood, N. A. ("the Bank") and its wholly-owned subsidiary, Tanglewood Financial Services Incorporated. These entities are collectively referred to as "the Company". All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans, management obtains independent appraisals for significant collateral. The Bank's loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Bank has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent on local economic conditions. While management uses available information to recognize losses on loans, further reduction in the carrying amounts of loans may be necessary based on changed in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of the change that is reasonable possible cannot be estimated. Investment Securities: Investment securities that are held for short-term resale are classified as trading securities and carried at fair value. F-21 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) Debt securities are classified as held-to-maturity when the Bank has the positive intent and ability to hold the securities to maturity. Securities held-to-maturity are carried at amortized cost. The amortization of premium and accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity. Debt securities not classified as held-to-maturity are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized gains and losses reported in other comprehensive income. Realized gains (losses) on securities available-for-sale are included in other income (expense) and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Gains and losses on sales of securities are determined on the specific-identification method. Declines in the fair value of individual held-to-maturity and available-for-sale securities below their cost that are other than temporary result in write-downs of the individual securities to their fair value. The related write-downs are included in earnings as realized losses. Mortgage-Backed Securities: Mortgage-backed securities represent participating interests in pools of long-term first mortgage loans originated and serviced by issuers of the securities. Mortgage-backed securities are carried at unpaid principal balances, adjusted for unamortized premiums and unearned discounts. Premiums and discounts are amortized using methods approximating the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Management intends and has the ability to hold such securities to maturity. Should any be sold, the cost of securities sold is determined using the specific identification method. Loans: Loans are stated at the amount of unpaid principal, less the allowance for loan losses and net deferred loan fees and unearned discounts. Unearned discounts on installment loans are recognized as income over the term of the loans, using a method that approximates the interest method. Loan origination and commitment fees, as well as certain direct origination costs, are deferred and amortized as a yield adjustment over the lives of the related loans using the interest method. Amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status. Interest income generally is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on such loans are applied as a reduction of the loan principal balance. Interest income on other impaired loans is recognized only to the extent of interest payments received. Allowance for Loan Losses: The allowance for loan losses is maintained at a level which, in management's judgment, is adequate to absorb credit losses inherent in the loan portfolio. The amount of the allowance is based on management's evaluation of the collectibility of the loan portfolio, including the nature of the portfolio, credit concentrations, trends in historical loss experience, specific impaired loans, economic conditions, and other risks inherent in the portfolio. Allowances for impaired loans are generally determined based on collateral values or the present value of estimated cash flows. Although management uses available information to recognize losses on loans, because F-22 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) of uncertainties associated with local economic conditions, collateral values, and future cash flows on impaired loans, it is reasonably possible that a material change could occur in the allowance for loan losses in the near term. However, the amount of the change that is reasonably possible cannot be estimated. The allowance is increased by a provision for loan losses, which is charged to expense, and reduced by charge-offs, net of recoveries. Changes in the allowance relating to impaired loans are charged or credited to the provision for loan losses. Premises and Equipment: Land is carried at cost. Other premises and equipment are carried at cost net of accumulated depreciation. Depreciation is computed using the straight-line and declining balance methods based principally on the estimated useful lives of the assets. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations. Other Real Estate: Real estate properties acquired through or in lieu of loan foreclosure are initially recorded at the lower of the Bank's carrying amount or fair value less estimated selling cost at the date of foreclosure. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, these assets are carried at the lower of their new cost basis or fair values less cost to sell. Costs of significant property improvements are capitalized, whereas costs relating to holding property are expensed. The portion of interest costs relating to development of real estate is capitalized. Valuations are periodically performed by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of its cost or fair value less cost to sell. The Company had no other real estate at December 31, 2001 and 2000. Income Taxes: Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes related primarily to differences between the basis of available-for-sale securities, allowance for loan losses, and accumulated depreciation for financial and income tax reporting. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The Company files consolidated income tax returns with its subsidiary. Mortgage Servicing Rights: Capitalized mortgage servicing assets consist of purchased and originated servicing rights. These rights are amortized in proportion to, and over the period of, the estimated future net servicing income stream of the underlying mortgage loans. Mortgage servicing rights are assessed for impairment based on the fair value of the right and any related derivative contracts. Impairment is evaluated by stratifying the mortgage servicing rights by interest rate bands. Fair value is determined considering market prices for similar assets or based on discounted cash flows using market-based prepayment estimates for similar coupons as well as incremental direct and indirect costs. The mortgage servicing operation was discontinued as of September 30, 2001, when it was sold to a third party. F-23 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) Employee Benefits: Effective April 1, 1998, the Company adopted a contributory 401(k) profit sharing plan, covering substantially all employees. The Company's contributions are determined annually, at the Company's discretion. Total plan expense for the years ended December 31, 2001 and 2000 was $59,186 and $35,290, respectively. Stock Option Plan: The Bank has a stock option plan under which 173,000 shares of common stock are reserved for issuance. Options have been granted to Bank officers and employees totaling 168,700 shares of common stock at exercise prices ranging from $10 to $30 per share. These options expire 10 years from the date of grant; options totaling 2,160 shares have been exercised to date. Deferred Compensation Plan: In November, 2001, the Board approved a deferred compensation plan for bank employees. The plan has an eight year vesting period with vesting occurring 20% annually beginning the fourth year following the date of award. Awards totaling 62,500 shares have been made at award values of $25 to $30 per share. Award shares are similar to stock option shares in nature, although they are not shares of common stock. Award values vary with changes in the market value of the common stock. Deferred compensation expense recognized in 2001 was $1,442. Note 2. Restrictions on Cash and Due from Banks The Bank is required to maintain reserve funds in cash or on deposit with the Federal Reserve Bank. The required reserve at December 31, 2001 and 2000, was $2,658,000 and $839,000, respectively. Note 3.

Note 8. Financial Instruments with Off-Balance-Sheet Risk In the normal course of business, the Bank has outstanding commitments to extend credit and standby letters of credit, which are not included in the accompanying consolidated financial statements. The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Bank uses the same credit policies in making commitments as it does for instruments that are included in the consolidated balance sheet instruments. Financial instruments whose contract amount represents credit risk were as follows: 2001 2000 ----------- ----------- Commitments to extend credit $35,879,954 $30,522,328 Standby letters of credit... 2,870,807 425,072 ----------- ----------- $38,750,761 $30,947,400 =========== =========== Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed F-27 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) necessary by the Bank upon extension of credit, is based on management's credit evaluation. Collateral held varies but may include accounts receivable, inventory, property and equipment, and income-producing commercial properties. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank's policy for obtaining collateral, and the nature of such collateral, is essentially the same as that involved in making commitments to extend credit. The Bank has not been required to perform on any financial guarantees during the past two years. The Bank has not incurred any losses on its commitments in either 2001 or 2000. Note 9. Commitments and Contingent Liabilities The Company is obligated under various noncancelable lease agreements for premises and equipment. Net rent expense was $375,233 and $296,944 for the years ended December 31, 2001 and 2000. The Company and the Bank are subject to claims and lawsuits which arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial statements of the Company. Note 10. Regulatory Matters Banks are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators, that if undertaken, could have a direct material effect on the Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines involving quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of: total risk-based capital and Tier I capital to risk-weighted assets, and Tier I capital to adjusted total assets. Management believes, as of December 31, 2001, that the Bank meets all capital adequacy requirements to which it is subject. Banks are also subject to certain restrictions on the amount of dividends that they may declare without prior regulatory approval. As of December 31, 2001, the Bank was categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank will have to maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as disclosed in the table below. There are no conditions or events that management believes have changed the Bank's prompt corrective action category. F-28 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) The Bank's actual and required capital amounts and ratios are as follows: To be Well For Capital Capitalized Under Adequacy Prompt Corrective Actual Purposes Action Provisions --------------------------- -------------------------- --------------------------- Amount Ratio Amount Ratio Amount Ratio ------- ------------------- ------- ------------------ ------- ------------------- (000's) (000's) (000's) As of December 31, 2001: Total Capital (to Risk Weighted Assets). $16,633 (greater or =)12.11% $10,990 (greater or =)8.00% $13,737 (greater or =)10.00% Tier 1 Capital (to Risk Weighted Assets) $15,418 (greater or =)12.67% $ 5,495 (greater or =)4.00% $ 8,242 (greater or =) 6.00% Tier 1 Capital (to Average Assets)...... $15,418 (greater or =) 7.92% $ 9,643 (greater or =)4.00% $12,054 (greater or =) 5.00% As of December 31, 2000: Total Capital (to Risk Weighted Assets). $12,611 (greater or =)13.69% $ 7,369 (greater or =)8.00% $ 9,211 (greater or =)10.00% Tier 1 Capital (to Risk Weighted Assets) $11,668 (greater or =)12.67% $ 3,684 (greater or =)4.00% $ 5,527 (greater or =) 6.00% Tier 1 Capital (to Average Assets)...... $11,668 (greater or =) 7.92% $ 5,891 (greater or =)4.00% $ 7,364 (greater or =) 5.00% Note 11.

Note 12. Related Party Transactions The Company's officers, directors and their associates, including corporations and firms of which they are officers or in which they and/or their families have an ownership interest, are customers of the Bank. Loans to officers, directors, and their associates were approximately $3,140,000 and $2,397,000 at December 31, 2001 and 2000, respectively. F-29 BANK OF TANGLEWOOD, N.A. AND SUBSIDIARY NOTES TO FINANCIAL STATEMENTS--(Continued) Note 13. Fair Value of Financial Instruments Management uses its best judgment in estimating the fair value of the Company's financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective year ends, and have not been reevaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each year end. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company's assets. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company's disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair value of the Company's financial instruments at December 31, 2001 and 2000. Financial Instruments Valued at Carrying Value. The carrying amounts of cash and due from banks, interest-bearing deposits with banks, federal funds sold and resale agreements and loans held for sale approximate their fair value. The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other borrowed funds maturing within 90 days approximate their fair values. The carrying amounts of accrued interest approximate their fair values. Available-for-Sale and Held-to-Maturity Securities. Fair values for securities, excluding restricted equity securities, are based on available quoted market prices. If quoted market prices are unavailable, fair values are based on quoted market prices of comparable instruments. For unquoted securities for which no comparable instruments exists, the reported fair value is estimated on the basis of cost, book or appraised value as deemed appropriate by management. Available-for-sale securities are carried at their aggregate fair value. Loans. For variable-rate commercial loans that reprice frequently (within a relatively short time frame) and have no significant change in credit risk, fair values are based on carrying values. Residential first mortgages are based on quoted market prices of similar loans. Fair values for certain junior mortgage loans, consumer installment loans, credit-card loans, and other consumer loans are estimated using discounted cash flow models. The discount rates are based on current market interest rates for similar types of loans. Fair values for commercial real estate and commercial loans that do not reprice or do not mature within relatively short time frames are estimated using discounted cash flow analyses. The discount rates used are those currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for impaired loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Deposits. The fair values for demand deposits and deposits with no defined maturity are determined to be the amount payable on demand at the reporting date. The fair values for fixed-maturity deposits are estimated using discounted cash flow models based on rates currently offered for the relevant product types with similar remaining maturities.

Unless otherwise modified in writing, BOKF also shall cause Tanglewood and its subsidiaries to honor all employment, severance, consulting and other compensation contracts AI-16 disclosed in Exhibit 10.o hereto between Tanglewood and any current or former director, officer or employee thereof, and all provisions for vested benefits or other vested amounts earned or accrued through the Closing Date under the Tanglewood benefit plans.

The Registration Statement prepared and filed under this paragraph 2.C., and any sale covered thereby, will be at BOKF's expense except for underwriting discounts or commissions, brokers' fees and the fees and disbursements of the undersigned's counsel related thereto. The undersigned will provide all information reasonably requested by BOKF for inclusion in the Registration Statement to be filed hereunder.

(the "Bank"), upon the consummation of the merger (the "Merger") of the Bank into TW Interim National Bank ("TW") pursuant to that certain Agreement and Plan of Merger dated May 15, 2002 by and among the Bank, TW and BOK Financial Corporation, you will be entitled to receive a cash payment (the "Payment") equal to the product of (i) the number of shares of Phantom Stock awarded under the Phantom Stock Agreement, multiplied by (ii) the value of a share of common stock of the Bank as of the date of the Merger, less the Award Value (as defined in the Phantom Stock Agreement). Under the terms of the Agreement and Plan of Merger, however, the Bank is required to obtain your waiver of a portion of the Payment that you would otherwise be entitled to receive under the Phantom Stock Agreement. Furthermore, if the Merger is not consummated (and there is no change in control of the Bank before then), you would not vest in any of the Payment until November 28, 2005, and you would not vest in all of the Payment until November 28, 2009. The amount of the Payment you would vest in at that time could be less than the amount of the Payment you would otherwise be entitled to receive upon consummation of the Merger. Therefore, in order to allow the Merger to be consummated, and to fix the amount and accelerate timing of the Payment, the Bank and you hereby agree that, notwithstanding any other agreement, plan, resolution or arrangement to the contrary, you hereby relinquish all rights to the Payment to the extent that the Payment relates to 100% of the Phantom Stock shares that, in the absence of the Merger, would have vested on or about November 28, 2009, plus 10% of the Phantom Stock shares that would have vested on or about November 28, 2008, plus such additional amount, if any, the payment of which would subject the Payment to the excise tax provided by Section 4999 of the Internal Revenue Code. The foregoing waiver, however, is void if the amount waived and relinquished is approved for payment by the shareholders of the Bank in a manner that meets the requirements of Section 280G(b)(5)(B) of the Internal Revenue Code.

Tidwell, Jr. ---------------------------------- Title: EVP/CFO ---------------------------------- AVII-1 ANNEX VIII September 19, 2002 Board of Directors Bank of Tanglewood, NA 500 Chimney Rock Road Houston, TX 77056 Dear Members of the Board: We understand that Bank of Tanglewood, N. A. ("Tanglewood"), a Texas corporation, and BOK Financial Corporation ("BOK Financial"), an Oklahoma corporation, have entered into an Agreement and Plan of Merger (the "Agreement") dated May 15, 2002, pursuant to which the Board of Directors of both Tanglewood and BOK Financial have determined that it is in the best interests of their respective shareholders to enter into a transaction pursuant to which Tanglewood will be merged with and into TW Interim National Bank, a wholly-owned subsidiary of BOK Financial (the "Merger"). As set forth in the Agreement, at the Effective Time of the Merger (as defined in the Agreement) all of the outstanding shares of Tanglewood stock (including any stock options, warrants, and rights to acquire stock) shall be converted into the right to receive merger consideration valued at $65 million. The $65 million merger consideration includes approximately $450,000 to be paid to Hovde Financial LLC ("Hovde") as Bank of Tanglewood's financial advisor and assumes the issuance to Tanglewood shareholders of $750,000 in BOK Financial common stock to be placed into an escrow account to compensate BOK Financial for any breaches in representations and warranties of Bank of Tanglewood which are discovered between completion of the merger and December 31, 2003. The $65 million merger consideration excludes the value of the benchmark price protection rights to be received pursuant to the merger. The merger consideration to be paid to Bank of Tanglewood shareholders by BOK Financial is made up of 100% BOK Financial common stock. In connection with the merger, you have requested our opinion as to the fairness, from a financial point of view, of the Merger to the shareholders of Tanglewood. Hovde, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bidding, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. We are familiar with Tanglewood, having acted as its financial advisor in connection with, and having participated in the negotiations leading to, the Agreement. We are also familiar with BOK Financial, through our continued Merger negotiations and due diligence. We were retained by Tanglewood to act as its financial advisor in connection with the Merger. We will receive compensation from Tanglewood in connection with our services, a significant portion of which is contingent upon the consummation of the Merger. Tanglewood has agreed to indemnify us for certain liabilities arising out of our engagement. During the course of our engagement and for the purposes of the opinion set forth herein, we have: (i) reviewed the Agreement; (ii) reviewed certain historical publicly available business and financial information concerning Tanglewood and BOK Financial; (iii) reviewed certain internal financial statements and other financial and operating data concerning Tanglewood; (iv) analyzed certain financial projections prepared by the management of Tanglewood; (v) conducted meetings with members of the senior management of Tanglewood for the purpose of reviewing the future prospects of Tanglewood, including financial forecasts related to Bank of AVIII-1 Tanglewood's business, earnings, assets, liabilities and the amount and timing of cost savings and revenue enhancements (the "Synergies") expected to be achieved as a result of the Merger; (vi) conducted meetings with members of senior management of BOK Financial for purposes of reviewing historical financial information related to BOK Financial's business, earnings, assets and liabilities; (vii) evaluated the pro forma contribution of Tanglewood's assets, liabilities, equity and earnings to the pro forma company; (viii) reviewed the terms of recent merger and acquisition transactions, to the extent publicly available, involving banks and bank holding companies that we considered relevant; (ix) analyzed the pro forma impact of the Merger on the combined company's earnings per share, consolidated capitalization and financial ratios; and, (x) performed such other analyses and considered such other factors as we have deemed appropriate. We also took into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our knowledge of the banking industry and our general experience in securities valuations. In rendering this opinion, we have assumed, without independent verification, the accuracy and completeness of the financial and other information and representations contained in the materials provided to us by Tanglewood and BOK Financial and in the discussions with Tanglewood and BOK Financial managements. In that regard, we have assumed that the financial forecasts, including, without limitation, the Synergies and projections regarding under-performing and non-performing assets and net charge-offs have been reasonably prepared on a basis reflecting the best currently available information and judgments and estimates of Tanglewood and BOK Financial and that such forecasts will be realized in the amounts and at the times contemplated thereby. We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto and have assumed that such allowances for Tanglewood and BOK Financial are in the aggregate adequate to cover such losses. We were not retained to and did not conduct a physical inspection of any of the properties or facilities of Tanglewood or BOK Financial. In addition, we have not reviewed individual credit files nor have we made an independent evaluation or appraisal of the assets and liabilities of Tanglewood or BOK Financial and we were not furnished with any such evaluations or appraisals. We have assumed that the Merger will be consummated substantially in accordance with the terms set forth in the Agreement. We have further assumed that the Merger will be accounted for as a purchase-of-interests under generally accepted accounting principles. We have assumed that the Merger is, and will be, in compliance with all laws and regulations that are applicable to Tanglewood or BOK Financial. In rendering this opinion, we have been advised by Tanglewood and BOK Financial and we have assumed that there are no factors that would impede any necessary regulatory or governmental approval of the Merger and we have further assumed that, in the course of obtaining the necessary regulatory and governmental approvals, no restriction will be imposed on BOK Financial or the surviving corporation that would have a material adverse effect on BOK Financial or the contemplated benefits of the Merger. We have also assumed that there would not occur any change in applicable law or regulation that would cause a material adverse change in the prospects or operations of BOK Financial or the surviving corporation after the Merger. Our opinion is based solely upon the information available to us and the economic, market and other circumstances as they exist as of the date hereof. Events occurring and information that becomes available after the date hereof could materially affect the assumptions and analyses used in preparing this opinion. We have not undertaken to reaffirm or revise this opinion or otherwise comment upon any events occurring or information that becomes available after the date hereof. AVIII-2 This letter is solely for the information of the Board of Directors of Tanglewood and is not to be used, circulated, quoted or otherwise referred to for any other purpose, nor is it to be filed with, included in or referred to in whole or in part in any registration statement, proxy statement or any other document, except in each case in accordance with our prior written consent which shall not be unreasonably withheld; provided, however, that we hereby consent to the inclusion and reference to this letter in any registration statement, proxy statement, information statement or tender offer document to be delivered to the holders of Tanglewood Stock in connection with the Merger if and only if this letter is quoted in full or attached as an exhibit to such document and this letter has not been withdrawn prior to the date of such document. Subject to the foregoing and based on our experience as investment bankers, our activities and assumptions as described above, and other factors we have deemed relevant, we are of the opinion as of the date hereof that the merger consideration as set forth in the Agreement is fair, from a financial point of view, to the shareholders of Tanglewood. Sincerely, /s/ HOVDE FINANCIAL LLC HOVDE FINANCIAL LLC AVIII-3 ANNEX IX 12 USCA (S) 215 12 U.S.C.A. (S) 215 Provisions of the National Bank Act Relating to Rights of Dissenting Shareholders (S) 215a. Merger of national banks or State banks into national banks (a) Approval of Comptroller, board and shareholders; merger agreement; notice; capital stock; liability of receiving association One or more national banking associations or one or more State banks, with the approval of the Comptroller, under an agreement not inconsistent with this subchapter, may merge into a national banking association located within the same State, under the charter of the receiving association. The merger agreement shall-- (1) be agreed upon in writing b a majority of the board of directors of each association or State bank participating in the plan of merger; (2) be ratified and confirmed by the affirmative vote of the shareholders of each such association or State bank owning at least two-thirds of its capital stock outstanding, or by a greater proportion of such capital stock in the case of a State bank if the laws of the State where it is organized so require, at a meeting to be held on the call of the directors, after publishing notice of the time, place, and object of the meeting for four consecutive weeks in a newspaper of general circulation published in the place where the association or State bank is located, or , if there is not such newspaper, then in the newspaper of general circulation published nearest thereto, and after sending such notice to each shareholder of record by certified or registered mail at least ten days prior to the meeting, except to those shareholders who specifically waive notice, but any additional notice shall be given to the shareholders of such State bank which may be required by the laws of the State where it is organized. Publication of notice may be waived, in cases where the Comptroller determines that an emergency exists justifying such waiver, by unanimous action of the shareholders of the association or State banks; (3) specify the amount of the capital stock of the receiving association, which shall not be less than that required under existing law for the organization of a national bank in the place in which it is located and which will be outstanding upon completion of the merger, the amount of stock (if any) to be allocated, and cash (if any) to be paid, to the shareholders of the association or State bank being merged into the receiving association; and (4) provide that the receiving association shall be liable for all liabilities of the association or State bank being merged into the receiving association. (b) Dissenting shareholders If a merger shall be voted for at the called meetings by the necessary majorities of the shareholders of each association or State bank participating in the plan of merger, and thereafter the merger shall be approved by the Comptroller, any shareholder of any association or State bank to be merged into the receiving association who has voted against such merger at the meeting of the association or bank of which he is a stockholder, or has given notice in writing at or prior to such meeting to the presiding officer that he dissents from the plan of merger, shall be entitled to receive the value of the shares so held by him when such merger shall be approved by the Comptroller upon written request made to the receiving association at any time before thirty days after the date of consummation of the merger, accompanied by the surrender of his stock certificates. AIX-1 12 USCA (S) 215 12 U.S.C.A. (S) 215 (c) Valuation of shares The value of the shares of any dissenting shareholder shall be ascertained, as of the effective date of the merger, by an appraisal made by a committee of three persons, composed of (1) one selected y the vote of the holders of the majority of the stock, the owners of which are entitled to payment in cash; (2) one selected by the directors of the receiving association; and (3) one selected by the two so selected. The valuation agreed upon by any two of the three appraisers shall govern. If the value so fixed shall not be satisfactory to any dissenting shareholder who has requested payment, that shareholder may, within five days after being notified of the appraised value of his shares, appeal to the Comptroller, who shall cause a reappraisal to be made which shall be final and binding as to the value of the shares of the appellant. (d) Application to shareholders of merging associations; appraisal by Comptroller; expenses of receiving association; sale and resale of shares; State appraisal and merger law If, within ninety days from the date of consummation of the merger, for any reason one or more of the appraisers is not selected as herein provided, or the appraisers fail to determine the value of such shares, the Comptroller shall upon written request of any interested party cause an appraisal to be made which shall be final and binding on all parties. The expenses of the Comptroller in making the reappraisal or the appraisal, as the case may be, shall be paid by the receiving association. The value of the shares ascertained shall be promptly paid to the dissenting shareholders by the receiving association. The shares of stock of the receiving association which would have been delivered to such dissenting shareholders had they not requested payment shall be sold by the receiving association at an advertised public auction, and the receiving association shall have the right to purchase any of such shares at such public auction, if it is the highest bidder therefor, for the purpose of reselling such shares within thirty days thereafter to such person or persons and at such price not less than par as its board of directors by resolution may determine. If the shares are sold at public auction at a price greater than the amount paid to the dissenting shareholders, the excess in such sale price shall be paid to such dissenting shareholders. The appraisal of such shares of stock in any State bank shall be determined in the manner prescribed by the law of the State in such cases, rather than as provided in this section, if such provision is made in the State law; and no such merger shall be in contravention of the law of the State under which such bank is incorporated. The provisions of this subsection shall apply only to shareholders of (and stock owned by them in) a bank or association being merged in the receiving association. (e) Status of receiving association; property rights and interests vested and held as fiduciary The corporate existence of each of the merging banks or banking associations participating in such merger shall be merged into and continued in the receiving association and such receiving association shall be deemed to be the same corporation as each bank or banking association participating in the merger. All rights, franchises, and interests of the individual merging banks or banking associations in and to every type of property (real, personal, and mixed) and choses in action shall be transferred to and vested in the receiving association by virtue of such merger without any deed or other transfer. The receiving association, upon the merger and without any order or other action on the part of any court or otherwise, shall hold and enjoy all rights of property, franchises, and interests, including appointments, designations, and nominations, and all other rights and interests as trustee, executor, administrator, registrar of stocks and bonds, guardian of estates, assignee, receiver, and committee of estates of lunatics, and in every other fiduciary capacity, in the same manner and to the same extent as such rights, franchises, and interests were held or enjoyed by any one of the merging banks or banking associations at the time of the merger, subject to the conditions hereinafter provided. AIX-2 12 USCA (S) 215 12 U.S.C.A. (S) 215 (f) Removal as fiduciary; discrimination Where any merging bank or banking association, at the time of the merger, was acting under appointment of any court as trustee, executor, administrator, registrar of stocks and bonds, guardian of estates, assignee, receiver, or committee of estates of lunatics, or in any other fiduciary capacity, the receiving association shall be subject to removal by a court of competent jurisdiction in the same manner and to the same extent as was such merging bank or banking association prior to the merger. Nothing contained in this section shall be considered to impair in any manner the right of any court to remove the receiving association and to appoint in lieu thereof a substitute trustee, executor, or other fiduciary, except that such right shall not be exercised in such a manner as to discriminate against national banking associations, nor shall any receiving association be removed solely because of the fact that it is a national banking association. (g) Issuance of stock by receiving association; preemptive rights Stock of the receiving association may be issued as provided by the terms of the merger agreement, free from any preemptive rights of the shareholders of the respective merging banks. AIX-3 BC -- 259 BANKING ISSUANCE -------------------------------------------------------------------------------- Comptroller of the Currency Administrator of National Banks -------------------------------------------------------------------------------- Type: Banking Circular Subject: Stock Appraisals -------------------------------------------------------------------------------- TO: Chief Executive Officers of National Banks, Deputy Comptrollers (District), Department and Division Heads, and Examining Personnel PURPOSE This Banking Circular informs all national banks of the valuation methods used by the Office of the Comptroller of the Currency (OCC) to estimate the value of a bank's shares when requested to do so by a shareholder dissenting to the conversion, merger, or consolidation of its bank. The results of appraisals performed by the OCC between January 1, 1985, and September 30, 1991 are summarized. References: 12 U.S.C. 214a, 215 and 215a; 12 CFR 11.590 (Item 2) BACKGROUND Under 12 U.S.C. Section 214a, a shareholder dissenting from a conversion, consolidation, or merger involving a national bank is entitled to receive the value of his or her shares from the resulting bank. A valuation of the shares shall be made by a committee of three appraisers (a representative of the dissenting shareholder, a representative of the resulting bank, and a third appraiser selected by the other two). If the committee is formed and renders an appraisal that is acceptable to the dissenting shareholder, the process is complete and the appraised value of the shares is paid to the dissenting shareholder by the resulting bank. If, for any reason, the committee is not formed or if it renders an appraisal that is not acceptable to the dissenting shareholder, an interested party may request an appraisal by the OCC. 12 U.S.C. Section 215 provides these appraisal rights to any shareholder dissenting to a consolidation. Any dissenting shareholder of a target bank in a merger is also entitled to these appraisal rights pursuant to 12 U.S.C. Section 215a. The above provides only a general overview of the appraisal process. The specific requirements of the process are set forth in the statutes themselves. -------------------------------------------------------------------------------- Date: March 10, 1992 Page 1 of 4 AIX-4 BC -- 259 BANKING ISSUANCE -------------------------------------------------------------------------------- Comptroller of the Currency Administrator of National Banks -------------------------------------------------------------------------------- Type: Banking Circular Subject: Stock Appraisals -------------------------------------------------------------------------------- METHODS OF VALUATION USED Through its appraisal process, the OCC attempts to arrive at a fair estimate of the value of a bank's shares. After reviewing the particular facts in each case and the available information on a bank's shares, the OCC selects an appropriate valuation method, or combination of methods, to determine a reasonable estimate of the shares' value. Market Value The OCC uses various methods to establish the market value of shares being appraised. If sufficient trading in the shares exists and the prices are available from direct quotes from the Wall Street Journal or a market-maker, those quotes are considered in determining the market value. If no market value is readily available, or if the market value available is not well established, the OCC may use other methods of estimating market value, such as the investment value and adjusted book value methods. Investment Value Investment value requires an assessment of the value to investors of a share in the future earnings of the target bank. Investment value is estimated by applying an average price/earnings ratio of banks with similar earnings potential to the earnings capacity of the target bank. The peer group selection is based on location, size, and earnings patterns. If the state in which the subject bank is located provides a sufficient number of comparable banks using location, size and earnings patterns as the criteria for selection, the price/earnings ratios assigned to the banks are applied to the earnings per share estimated for the subject bank. In order to select a reasonable peer group when there are too few comparable independent banks in a location that is comparable to that of the subject bank, the pool of banks from which a peer group is selected is broadened by including one-bank holding company banks in a comparable location, and/or by selecting banks in less comparable locations, including adjacent states, that have earnings patterns similar to the subject bank. Adjusted Book Value The OCC also uses an "adjusted book value" method for estimating value. Historically, the OCC has not placed any weight on the bank's "unadjusted book value", since that value is based on historical acquisition costs of the bank's assets, and does not reflect investors' perceptions of the value of the bank as an ongoing concern. Adjusted book value is calculated by multiplying the book value of the target bank's assets per share times the average market price to book value ratio of comparable banking organizations. The average market price to book value ratio measures the premium or discount to book value, which investors attribute to shares of similarly situated banking organizations. -------------------------------------------------------------------------------- Date: March 10, 1992 Page 2 of 4 AIX-5 BC -- 259 BANKING ISSUANCE -------------------------------------------------------------------------------- Comptroller of the Currency Administrator of National Banks -------------------------------------------------------------------------------- Type: Banking Circular Subject: Stock Appraisals -------------------------------------------------------------------------------- Both the investment value method and the adjusted book value method present appraised values which are based on the target bank's value as a going concern. These techniques provide estimates of the market value of the shares of the subject bank. OVERALL VALUATION The OCC may use more than one of the above-described methods in deriving the value of shares of stock. If more than one method is used, varying weights may be applied in reaching an overall valuation. The weight given to the value by a particular valuation method is based on how accurately the given method is believed to represent market value. For example, the OCC may give more weight to a market value representing infrequent trading by shareholders than to the value derived from the investment value method when the subject bank's earnings trend is so irregular that it is considered to be a poor predictor of future earnings. PURCHASE PREMIUMS For mergers and consolidations, the OCC recognizes that purchase premiums do exist and may, in some instances, be paid in the purchase of small blocks of shares. However, the payment of purchase premiums depends entirely on the acquisition or control plans of the purchasers, and such payments are not regular or predictable elements of market value. Consequently, the OCC's valuation methods do not include consideration of purchase premiums in arriving at the value of shares. STATISTICAL DATA The chart below lists the results of appraisals the OCC performed between January 1, 1985 and September 30, 1991. The OCC provides statistical data on book value and price/earnings ratios for comparative purposes, but does not necessarily rely on such data in determining the value of the banks' shares. Dissenting shareholders should not view these statistics as determinative for future appraisals. In connection with disclosures given to shareholders under 12 CFR 11.590 (Item 2), banks may provide shareholders a copy of this Banking Circular or disclose the information in the Banking Circular, including the past results of OCC appraisals. If the bank discloses the past results of the OCC appraisals, it should advise shareholders that: (1) the OCC did not rely on all the information set forth in the chart in performing each appraisal; and, (2) the OCC's past appraisals are not necessarily determinative of its future appraisals of a particular bank's shares. -------------------------------------------------------------------------------- Date: March 10, 1992 Page 3 of 4 AIX-6 BC -- 259 BANKING ISSUANCE -------------------------------------------------------------------------------- Comptroller of the Currency Administrator of National Banks -------------------------------------------------------------------------------- Type: Banking Circular Subject: Stock Appraisals -------------------------------------------------------------------------------- APPRAISAL RESULTS OCC Average Price/ Appraisal Price Book Earnings Ratio Appraisal Date Value Offered Value of Peer Group -------------- --------- -------- -------- -------------- 1/1/85....................... 107.05 110 178.29 5.3 1/2/85....................... 73.16 NA 66.35 6.8 1/15/85...................... 53.41 60 83.95 4.8 1/31/85...................... 22.72 20 38.49 5.4 2/1/85....................... 30.63 24 34.08 5.7 2/25/85...................... 27.74 27.55 41.62 5.9 4/30/85...................... 25.98 35 42.21 4.5 7/30/85...................... 3,153.10 2,640.00 6,063.66 NC 9/1/85....................... 17.23 21 21.84 4.7 11/22/85..................... 316.74 338.75 519.89 5.0 11/22/85..................... 30.28 NA 34.42 5.9 12/16/85..................... 66.29 77 89.64 5.6 12/27/85..................... 60.85 57 119.36 5.3 12/31/85..................... 61.77 NA 73.56 5.9 12/31/85..................... 75.79 40 58.74 12.1 3/14/86...................... 59.02 200 132.2 3.1 4/21/86...................... 40.44 35 43.54 6.4 5/2/86....................... 15.5 16.5 23.69 5.0 7/3/86....................... 405.74 NA 612.82 3.9 7/31/86...................... 297.34 600 650.63 4.4 8/22/86...................... 103.53 106.67 136.23 NC 12/26/86..................... 16.66 NA 43.57 4.0 12/31/86..................... 53.39 95.58 69.66 7.1 5/1/87....................... 186.42 NA 360.05 5.1 6/11/87...................... 50.46 70 92.35 4.5 6/11/87...................... 38.53 55 77.75 4.5 7/31/87...................... 13.1 NA 20.04 6.7 8/26/87...................... 55.92 57.52 70.88 NC 8/31/87...................... 19.55 23.75 30.64 5.0 8/31/87...................... 10.98 NA 17.01 4.2 10/6/87...................... 56.48 60 73.11 5.6 3/15/88...................... 297.63 NA 414.95 6.1 6/2/88....................... 27.26 NA 28.45 5.4 6/30/88...................... 137.78 NA 215.36 6.0 8/30/88...................... 768.62 677 1,090.55 10.7 3/31/89...................... 773.62 NA 557.3 7.9 5/26/89...................... 136.47 180 250.42 4.5 5/29/90...................... 9.87 NA 11.04 9.9 -------- * The "Appraisal Date" is the consummation date for the conversion, consolidation, or merger.

(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: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the 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; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; (2) that, for the purpose 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 of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) to remove from registration by means of a 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 any 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)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (2) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for 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 of such securities at that time shall be deemed to be the initial bona fide offering thereof. (d) Insofar as indemnification for liabilities arising under the Securities Act 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 SEC such indemnification is against public policy as expressed in the Securities 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 a director, officer or II-2 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 its 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 Securities Act and will be governed by the final adjudication of such issue. (e) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
