================================================================================

     The board of directors of Texas Bancshares, Inc. has approved the sale of
TBI to Wells Fargo & Company. The sale requires the approval of TBI's
shareholders. A special meeting of shareholders will be held to vote on the
proposed sale. The date, time and place of the meeting are as follows:

     __________  _________, 1999
     _____  _.m., local time
     ___________________________
     ___________________________

     If the sale is completed, Wells Fargo will exchange approximately $34.2988
of its common stock for each outstanding share of TBI common stock.

     The exchange ratio, or the number of shares of Wells Fargo common stock you
will receive for each share of TBI common stock you own, will be determined by
dividing the share value of approximately $34.2988 by a measurement price. The
measurement price will be the average of the closing prices of a share of Wells
Fargo common stock as reported on the New York Stock Exchange for the period of
10 trading days ending on the day immediately before the special meeting.

     The following table shows the approximate exchange ratios that would result
from four different measurement prices, each based on a share value of $34.2988.

be known until immediately before the special meeting. The closing price of
Wells Fargo common stock on __________ was $__ a share.

     This proxy statement-prospectus provides detailed information about the
proposed acquisition. Please read this entire document carefully. You can find
additional information about Wells Fargo from documents filed with the
Securities Exchange Commission.

     Whether or not you plan to attend the meeting, please complete and mail the
enclosed proxy sheet. If you sign, date and mail your proxy sheet without
indicating how you want to vote, your proxy will be voted in favor of the
transaction. If you fail to return your proxy sheet, the effect will be the same
as a vote against the transaction.

     No vote of Wells Fargo stockholders is required to approve the transaction.


                                             Fredrick Erck
                                             Chairman of the Board and

                            ______________________

     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the Wells Fargo common stock to be
issued or determined if this proxy statement-prospectus is truthful or complete.
Any representation to the contrary is a criminal offense.

Questions and Answers About This Document
- --------------------------------------------------------------------------------

     What is the     This document serves as both a proxy statement of TBI and
 purpose of this     a prospectus of Wells Fargo. As a proxy statement, it's
       document?     being provided to you because TBI's board of directors is
                     soliciting your proxy for use at the special meeting. As a
                     prospectus, it's being provided to you because Wells Fargo
                     is offering to exchange shares of its common stock for your
                     shares of TBI common stock.

    Do I need to     Absolutely. Much of this proxy statement-prospectus
 read the entire     summarizes information that is in greater detail elsewhere
       document?     in this document or in the appendices to this document.
                     Each summary discussion is qualified by reference to the
                     full text. For example, the summary of the terms of the
                     merger agreement is qualified by the actual terms of the
                     merger agreement, a copy of which is attached as Appendix
                     A. As a result, to fully understand the merger and your
                     rights as a TBI shareholder, you will need to read
                     carefully this entire document including the attached
                     appendices.

  Is there other     Yes. Much of the business and financial information about
   information I     Wells Fargo that may be important to you is not included
should consider?     in or delivered with this document. Instead, this
                     information is incorporated by reference to other Wells
                     Fargo documents. This means that Wells Fargo may satisfy
                     its disclosure obligations to you by referring you to one
                     or more documents separately filed by Wells Fargo with the
                     SEC. For example, Wells Fargo's latest audited financial
                     statements and the latest description of its business are
                     incorporated into this proxy statement-prospectus by
                     reference to Wells Fargo's annual report on Form 10-K for
                     1998. Wells Fargo's 1998 Form 10-K, in turn, incorporates
                     financial statements and other information from Wells
                     Fargo's 1998 annual report to stockholders. The financial
                     statements and other information incorporated from the 1998
                     stockholders report are included in Exhibit 13 to the 1998
                     Form 10-K. As a result, to review Wells Fargo's latest
                     audited financial statements and the latest description of
                     its business, you'll need to obtain a copy of Wells Fargo's
                     Form 10-K

                     list of documents that Wells Fargo has incorporated by
                     reference into this proxy statement-prospectus and for
                     instructions on how to obtain copies of these documents.
                     The documents are available to you without charge.

                     information in this document or in the documents

     Exchange Of Wells   If the merger is completed, Wells Fargo will
      Fargo Shares For   exchange approximately $34.2988 of Wells  Fargo
            TBI Shares   common stock for each outstanding share of TBI common
             (page __)   stock. The exchange ratio, or the number of shares of
                         Wells Fargo common stock you will receive for each
                         share of TBI common stock you own, will be determined
                         by dividing the share value of approximately $34.2988
                         by a measurement price. The measurement price will be
                         the average of the closing prices of a share of Wells
                         Fargo common stock as reported on the New York Stock
                         Exchange for the period of 10 trading days ending on
                         the day immediately before the special meeting. The
                         following table shows the approximate exchange ratios
                         that would result from four different measurement
                         prices, each based on a share value of $34.2988.

                         The actual measurement price--and thus the actual
                         exchange ratio--will not be known until immediately
                         before the special meeting.

           Redemption    TBI has agreed to redeem for cash each TBI
       Of Unexercised    option that has not been exercised as of immediately
              Options    before the merger. The option redemption price for each
                         option share will equal $34.2988 minus the exercise
                         price of the option share. For example, the holder of
                         an option to purchase 1,000 shares of TBI common stock
                         at an exercise price of $16.65 a share would receive a
                         total of $17,648.80 in cash upon redemption of the

                         shares.

                         The tax treatment described above may not apply to

                         the merger's tax consequences.

                         own advisor for the tax consequences of exercising your
                         options before the merger or receiving cash upon
                         redemption of your options by TBI, as this document
                         does not address the tax consequences of either of

                         TBI common stock is fair to TBI shareholders from a
                         financial point of view. A copy of the fairness opinion
                         is attached to this proxy statement-prospectus as

            (page __)    at fair value, the acquired assets and assumed
                         liabilities of TBI. To the extent the total purchase
                         price exceeds the fair value of the assets acquired and
                         liabilities assumed, Wells Fargo will record goodwill.

Comparative         The following table shows comparative per share data for
 Per Common         Wells Fargo common stock on a historical and pro forma
 Share Data         combined basis and for TBI common stock on a historical and
                    pro forma equivalent basis. The information in the table
                    assumes that Wells Fargo will treat the merger as a purchase
                    and will exchange 0.8575 shares of its common stock for each
                    share of TBI common stock. This is the exchange ratio that
                    would result if the measurement price is $40.00. The actual
                    measurement price--and thus the actual exchange ratio--will
                    not be known until immediately before the special meeting.
                    The pro forma equivalent information for TBI is calculated
                    by multiplying the pro form basic and diluted earnings per
                    share, the historical cash dividends declared per share of
                    Wells Fargo common stock and the pro forma stockholders'
                    equity per share by the assumed exchange ratio of 0.8575.

                    You should read the data with the historical financial
                    statements and related notes of Wells Fargo and TBI. TBI's
                    financial statements are included in this document beginning
                    on page F-1. Wells Fargo's historical financial statements
                    are included or incorporated in documents filed by Wells
                    Fargo with the SEC. See "Where You Can Find More

   Voting and        All shares of TBI common stock represented at the special
Revocation Of        meeting by a properly Proxies executed proxy will be voted
      Proxies        in accordance with the instructions indicated on the proxy,
                     unless the proxy is revoked before a vote is taken. If you
                     sign and return a proxy without voting instructions, and do
                     not revoke the proxy, the proxy will be voted FOR the
                     merger.

                     You may revoke your proxy at any time before it is voted by
                     (a) filing either an instrument revoking the proxy or a
                     duly executed proxy bearing a later date with the corporate
                     secretary of TBI before or at the special meeting or (b)
                     voting the shares subject to the proxy in person at the
                     special meeting. Attendance at the special meeting will not
                     by itself result in your proxy being revoked.

                     A proxy may indicate that all or a portion of the shares
                     represented by the proxy are not being voted with respect
                     to a specific proposal. This could occur, for example, when
                     a broker is not permitted to vote shares held in the name
                     of a nominee on certain proposals in the absence of
                     instructions from the beneficial owner. Shares that are not
                     voted with respect to a specific proposal will be
                     considered as not present for that proposal, even though
                     the shares will be considered present for purposes of
                     determining a quorum and voting on other proposals.
                     Abstentions on a specific proposal will be considered as
                     present but will not be counted as voting in favor of the
                     proposal.

                     The proposal to approve the merger must be approved by the
                     holders of

                                       13
<PAGE>

                     at least two-thirds of the outstanding shares of TBI common
                     stock. Because approval of the merger requires the
                     affirmative vote of a specified percentage of outstanding
                     shares, not voting on the proposal will have the same
                     effect as voting against the proposal.


 Solicitation Of     In addition to solicitation by mail, directors, officers
         Proxies     and employees of TBI may solicit proxies from TBI
                     shareholders, either personally or by telephone or other
                     form of communication. None of the foregoing persons who
                     solicit proxies will be specifically compensated for such
                     services. Nominees, fiduciaries and other custodians will
                     be requested to forward soliciting materials to beneficial
                     owners and will be reimbursed for their reasonable expenses
                     incurred in sending proxy material to beneficial owners.
                     TBI will bear its own expenses in connection with any
                     solicitation of proxies for the special meeting.


   Other Matters     If an insufficient number of votes for the merger is
   Considered At     received before the scheduled At The Meeting meeting date,
     The Meeting     Wells Fargo and TBI may decide to postpone or adjourn the
                     special meeting. If this happens, proxies that have been
                     received that either have been voted for the merger or
                     contain no instructions will be voted for adjournment.

                     TBI's board of directors is not aware of any business to be
                     brought before the special meeting other than the proposals
                     to approve the merger. If other matters are properly
                     brought before the special meeting or any adjournments or
                     postponements of the meeting, the persons appointed as
                     proxies will have authority to vote the shares represented
                     by properly executed proxies in accordance with their
                     discretion and judgment as to the best interests of TBI.

                     "Comparison Of Stockholder Rights."


Background Of        Background of the Merger. During the first quarter of 1999,
  And Reasons        TBI received unsolicited For The Merger indications of
      For The        interest by certain financial institutions, including Wells
       Merger        Fargo. Due to the strong interest in TBI shown by other
                     financial institutions, TBI held discussions with two
                     investment banking firms, including Hoefer & Arnett,
                     Incorporated, regarding the value of TBI.

                     On April 1, 1999, TBI received a letter of intent from
                     Wells Fargo presenting a proposal to acquire 100% of the
                     outstanding capital stock of TBI by a merger or
                     consolidation of TBI and either Wells Fargo or an affiliate
                     of Wells Fargo in exchange for common stock of Wells Fargo.
                     TBI's board of directors held a special meeting on April 7,
                     1999 to consider and act upon the Wells Fargo letter of
                     intent. TBI's board of directors engaged in a comprehensive
                     discussion and analysis of the following factors in
                     determining whether to enter into the letter of intent with
                     Wells Fargo:

                     .      prior to any investigation of TBI's books, records
                            and properties, the requirement that Wells Fargo
                            enter into a confidentiality agreement;

                     .      TBI's previous discussions with two investment
                            banking firms regarding the value of TBI;

                     .      TBI's receipt of unsolicited indications of interest
                            by other financial institutions; and

                     .      the intrinsic value of the Wells Fargo common stock
                            and enterprise.

                     After completing its analysis, TBI's board of directors
                     authorized moving forward with negotiations with Wells
                     Fargo and authorized and approved the execution and
                     delivery of a confidentiality agreement and

                                       15
<PAGE>

                     the letter of intent. TBI's board of directors also
                     authorized the engagement of Hoefer & Arnett as TBI's
                     financial advisor to render an opinion with regard to the
                     fairness, from the perspective of the shareholders of TBI,
                     of the financial terms of the proposed transaction between
                     TBI and Wells Fargo.

                     After negotiating the terms of a definitive agreement,
                     TBI's board of directors met again on May 28, 1999 to
                     review the proposed merger agreement and consider the
                     transaction with Wells Fargo. Based primarily upon an
                     extensive discussion of the terms of the merger agreement
                     and of the financial condition and valuation for both TBI
                     and Wells Fargo, TBI's board of directors determined that
                     the transaction with Wells Fargo was advisable and in the
                     best interests of TBI and its shareholders. As a result,
                     TBI's board of directors authorized the execution and
                     delivery of the merger agreement.

                     TBI's Board of Directors' Reasons for the Merger. TBI's
                     board of directors believes that the merger is advisable
                     and in the best interests of TBI and its shareholders. In
                     reaching this determination, TBI's board of directors
                     considered a number of factors including, without
                     limitation, the following:

                     .      The transaction would give TBI's shareholders
                            greater liquidity, as there is currently no active
                            trading market for their shares of TBI common stock,
                            while Wells Fargo common stock is listed and traded
                            on the New York Stock Exchange.

                     .      The transaction is contemplated to be tax-free to
                            the TBI shareholders and the merger agreement
                            provides that it is a condition to TBI's obligations
                            to complete the merger that it shall have received
                            the opinion of KPMG LLP that no gain or loss will be
                            recognized by TBI shareholders to the extent they
                            receive Wells Fargo common stock in the merger. See
                            "The Merger--U.S. Federal Income Tax Consequences of
                            the Merger."

                     .      The consideration to be received by TBI shareholders
                            in the merger, which TBI's board of directors
                            believed to represent an attractive premium and to
                            be fair to the TBI shareholders from a financial
                            point of view. TBI's board of directors'
                            determination was based on, among other things, a
                            comparison of the terms of the proposed transaction
                            with other recent bank mergers and acquisitions, the
                            evaluation of publicly available information
                            regarding Wells Fargo, the review and evaluation of
                            other information concerning the valuation of banks
                            and analyses of recent bank acquisitions, and the
                            review and evaluation of financial information and
                            analyses regarding Wells Fargo and TBI. TBI's board

                            that the premium to be received by the TBI
                            shareholders pursuant to the merger agreement is
                            within the range of premiums in recent comparable
                            bank transactions in the State of Texas.

                     .      The opinion of Hoefer & Arnett, its financial
                            advisor, that the consideration to be received by
                            the TBI shareholders in the merger is fair to the
                            TBI shareholders from a financial point of view. See
                            "The Merger--Opinion Of TBI's Financial Advisor."

                     .      The current "favorable" environment for purchase
                            price premiums in acquisitions of financial
                            institutions and the likelihood of such favorable
                            conditions continuing.

                     .      The growth prospects of TBI's subsidiary banks,
                            First National Bank of South Texas and The Bank of
                            South Texas and the fact that the present size and
                            market position of TBI and its subsidiary banks make
                            acquisitions of other banking institutions
                            difficult.

                     .      Wells Fargo's successful expansion record, allowing
                            TBI shareholders who retain Wells Fargo common stock
                            the opportunity to own stock in an institution that
                            has demonstrated meaningful and consistent growth in
                            recent years.

                     .      The state of the banking industry generally and the
                            increased competition brought about by
                            consolidation, deregulation and other factors, as
                            well as the financial size and resources necessary
                            to compete in this environment.

                     .      Wells Fargo's record in enhancing shareholder value.

                     TBI's board of directors has unanimously approved the
                     merger agreement and recommends that TBI shareholders
                     approve the merger agreement at the special meeting.


      Opinion Of     The fairness opinion of TBI's financial advisor, Hoefer &
 TBI's Financial     Arnett, Incorporated, is Advisor described below. The
         Advisor     description contains Hoefer & Arnett's projections,
                     estimates and/or other forward-looking statements about the
                     future earnings or other measures of the future performance
                     of Wells Fargo and TBI. You should not rely on any of these
                     statements as having been made or adopted by Wells Fargo or
                     TBI.

                     TBI's board of directors retained Hoefer & Arnett,
                     Incorporated to render, as investment bankers, a written
                     opinion to TBI's board of directors as to the fairness,
                     from a financial point of view, to the shareholders of TBI
                     of the terms of the proposed merger of a wholly-

<PAGE>

                     owned subsidiary of Wells Fargo with and into TBI in
                     accordance with the terms and conditions of the merger
                     agreement, as amended. No limitations were imposed by TBI's
                     board of directors upon Hoefer & Arnett with respect to the
                     investigations made or procedures followed in rendering the
                     fairness opinion.

                     A copy of the fairness opinion of Hoefer & Arnett, dated as
                     of the date of this proxy statement-prospectus, which sets
                     forth certain assumptions made, matters considered and
                     limits on the review undertaken by Hoefer & Arnett, is
                     attached as Appendix B to this proxy statement-prospectus.
                     TBI shareholders are urged to read the fairness opinion in
                     its entirety. The following summary of the procedures and
                     analysis performed, and assumptions used by Hoefer &
                     Arnett, is qualified in its entirety by reference to the
                     text of the fairness opinion. Hoefer & Arnett's fairness
                     opinion is directed to TBI's board of directors only and is
                     directed only to the financial terms of the transaction and
                     does not constitute a recommendation to any TBI shareholder
                     as to how such shareholder should vote at the special
                     meeting.

                     In arriving at its opinion, Hoefer & Arnett reviewed and
                     analyzed, among other things, the following: (i) the merger
                     agreement; (ii) annual reports to shareholders of TBI and
                     Wells Fargo for the years ended December 31, 1997 and
                     December 31, 1998; (iii) quarterly consolidated financial
                     statements for bank holding companies on Form FR Y-9C as
                     filed with the Federal Reserve Board for TBI and Wells
                     Fargo for the quarters ended March 31, 1999, December 31,
                     1998, September 30, 1998 and June 30, 1998 and March 31,
                     1998; (iv) certain other publicly available financial and
                     other information concerning TBI and Wells Fargo and the
                     trading markets for the publicly traded securities of Wells
                     Fargo; and (v) publicly available information concerning
                     other banks and bank holding companies, the trading markets
                     for their securities and the nature and terms of certain
                     other merger transactions we believe relevant to our
                     inquiry. Hoefer & Arnett held discussions with senior
                     management of TBI and Wells Fargo concerning their past and
                     current operations, financial condition and prospects, as
                     well as the results of regulatory examinations.

                     Hoefer & Arnett reviewed with senior management of TBI
                     earnings projections for 1999 through 2003 for TBI as a
                     stand-alone entity, assuming the merger does not occur. TBI
                     senior management prepared such projections.

                     In conducting its review and in arriving at its opinion,
                     Hoefer & Arnett relied upon and assumed the accuracy and
                     completeness of the financial and other information
                     provided to it or publicly available, and did not attempt
                     to independently verify the same. Hoefer & Arnett relied
                     upon

                                       18
<PAGE>

                     the management of TBI as to the reasonableness of the
                     financial and operating forecasts and projections (and the
                     assumptions and bases therefor) provided to it, and Hoefer
                     & Arnett assumed that such forecasts and projections
                     reflect the best currently available estimates and
                     judgments of TBI management. Hoefer & Arnett also assumed,
                     without independent verification, that the aggregate
                     allowances for loan losses for Wells Fargo and TBI are
                     adequate to cover such losses. Hoefer & Arnett did not make
                     or obtain any evaluations or appraisals of the properties
                     of Wells Fargo or TBI, nor did it examine any individual
                     loan credit files. For purposes of its opinion, Hoefer &
                     Arnett assumed that the merger will have the tax,
                     accounting and legal effects described in the merger
                     agreement and relied, as to legal matters, exclusively on
                     counsel to TBI. Hoefer & Arnett's opinion is limited to the
                     fairness, from a financial point of view, to the holders of
                     shares of TBI common stock of the terms of the proposed
                     merger of a wholly-owned subsidiary of Wells Fargo with and
                     into TBI and does not address TBI's underlying business
                     decision to proceed with the merger.

                     As more fully discussed below, Hoefer & Arnett considered
                     such financial and other factors as Hoefer & Arnett deemed
                     appropriate under the circumstances, including among others
                     the following: (i) the historical and current financial
                     position and results of operations of Wells Fargo and TBI,
                     including interest income, interest expense, net interest
                     income, net interest margin, provision for loan losses,
                     non-interest income, non-interest expense, earnings,
                     dividends, internal capital generation, book value,
                     intangible assets, return on assets, return on
                     shareholders' equity, capitalization, the amount and type
                     of non-performing assets, loan losses and the reserve for
                     loan losses, all as set forth in the financial statements
                     for Wells Fargo and TBI; (ii) the assets and liabilities of
                     Wells Fargo and of TBI, including the loan, investment and
                     mortgage portfolios, deposits, other liabilities,
                     historical and current liability sources and costs and
                     liquidity; and (iii) the nature and terms of certain other
                     merger transactions involving banks and bank holding
                     companies. Hoefer & Arnett also took into account its
                     assessment of general economic, market and financial
                     conditions and its experience in other transactions, as
                     well as its experience in securities valuation and its
                     knowledge of the banking industry generally. Hoefer &
                     Arnett's opinion is necessarily based upon conditions as
                     they existed and can be evaluated on the date of its
                     opinion and the information made available to it through
                     that date.

                     In connection with rendering its fairness opinion to TBI's
                     board of directors, Hoefer & Arnett performed certain
                     financial analyses, which are summarized below. Hoefer &
                     Arnett believes that its analysis must be considered as a
                     whole and that selecting portions of such analysis and the
                     factors considered therein, without considering all factors
                     and

                                       19
<PAGE>

                     analysis, could create an incomplete view of the analysis
                     and the processes underlying Hoefer & Arnett's fairness
                     opinion. The preparation of a fairness opinion is a complex
                     process involving subjective judgments and is not
                     necessarily susceptible to partial analysis or summary
                     description. In its analyses, Hoefer & Arnett made numerous
                     assumptions with respect to industry performance, business
                     and economic conditions, and other matters, many of which
                     are beyond the control of Wells Fargo and TBI. Any
                     estimates contained in Hoefer & Arnett's analyses are not
                     necessarily indicative of future results or values, which
                     may be significantly more or less favorable than such
                     estimates. Estimates of values of companies do not purport
                     to be appraisals or necessarily reflect the prices at which
                     companies or their securities may actually be sold. Except
                     as described below, none of the financial analyses
                     performed by Hoefer & Arnett was assigned a greater
                     significance by Hoefer & Arnett than any other.

                     The financial forecasts and projections of TBI prepared by
                     Hoefer & Arnett were based on projections provided by TBI
                     as well as Hoefer & Arnett's own assessment of general
                     economic, market and financial conditions. All such
                     information was reviewed with the respective management of
                     TBI. TBI does not publicly disclose internal management
                     financial forecasts and projections of the type provided to
                     Hoefer & Arnett in connection with its review of the
                     proposed merger. Such forecasts and projections were not
                     prepared with a view towards public disclosure. The
                     forecasts and projections prepared by Hoefer & Arnett were
                     based on numerous variables and assumptions, which are
                     inherently uncertain, including, without limitation,
                     factors related to general economic and market conditions.
                     Accordingly, actual results could vary significantly from
                     those set forth in such forecasts and projections.

                     Summary of Proposal. Hoefer & Arnett reviewed the terms of
                     the proposed transaction. At April 6, 1999, TBI had
                     1,966,536 common shares outstanding and 59,500 common stock
                     options outstanding with an aggregate exercise price of
                     $990,890. If not exercised, the holder will receive cash.
                     For purposes of Hoefer & Arnett's analysis, Hoefer & Arnett
                     assumed that all 59,500 options are exercised resulting in
                     an "Aggregate Share Amount" or total purchase price, of
                     $69,490,890. A purchase price of $69,490,890, or
                     approximately $34.30, per share represents a price to book
                     value at March 31, 1999 (adjusted for the exercise of the
                     options) of 2.08, a price to tangible book value of 2.38, a
                     price to 1998 earnings of 20.89 and a price to assets ratio
                     of 17.86% (based on March 31, 1999 total assets as adjusted
                     for the exercise of the options).

                     Comparable Transaction Analysis. Hoefer & Arnett reviewed
                     certain

                                       20
<PAGE>

                     information relating to selected bank mergers announced
                     between August 1, 1998 and May 26, 1999 in which the
                     acquired banking organization was located in the state of
                     Texas. This data was obtained from Sheshunoff Information
                     Services, Inc.

                     On the basis of the comparable transactions, Hoefer &
                     Arnett calculated a range of purchase prices as a multiple
                     of stated book value for the comparable transactions from a
                     low of 1.16 to a high of 4.40, with an average of 2.16.
                     These transactions indicated a range of $19.13 per share to
                     $72.56 per share, with an average of $35.62 per share for
                     TBI (based on March 31, 1999 stated equity of $16.49 per
                     share, as adjusted for the exercise of options).

                     On the basis of the comparable transactions, Hoefer &
                     Arnett calculated a range of purchase prices as a multiple
                     of earnings for the comparable transactions from a low of
                     9.52 to a high of 29.35, with an average of 17.26. These
                     transactions indicated a range of $15.61 per share to
                     $48.13 per share, with an average of $28.34 per share for
                     TBI (based on fully diluted 1998 earnings of $1.64 per
                     share).

                     Finally, Hoefer & Arnett calculated a range of purchase
                     prices as a percentage of total assets for the comparable
                     transactions from a low of 5.82% to a high of 28.96%, with
                     an average of 18.24%. These transactions indicated a range
                     of $11.18 per share to $55.63 per share, with an average of
                     $35.04 per share for TBI (based on March 31, 1999 total
                     assets of $389,158,890, as adjusted for the exercise of
                     options). The price to book value multiple, the price to
                     earnings multiple and the price to assets ratio resulting
                     from the terms of the merger agreement all fall within the
                     range of purchase prices calculated using the prices paid
                     in the comparable transactions.

                     Additionally, Hoefer & Arnett reviewed pricing information
                     on acquisitions announced by Wells Fargo (known as Norwest
                     Corporation prior to November 3, 1998) from January 1, 1997
                     to May 26, 1999, based on data obtained from Sheshunoff
                     Information Services, Inc. For the 15 transactions
                     reviewed, the price to book value multiple ranged from 1.46
                     to 3.89, with an average of 2.31. The price to earnings
                     multiple ranged from 5.23 to 31.41, with an average of
                     16.60. The price as a percentage of total assets ranged
                     from 14.09% to 28.37%, with an average of 20.42%. The price
                     to book value multiple, the price to earnings multiple and
                     the price to assets ratio resulting from the terms of the
                     merger agreement all fall within the range of pricing
                     multiples paid by Wells Fargo in previous transactions.

                     Present Value Analysis. Hoefer & Arnett calculated the
                     present value of TBI assuming that TBI remained
                     independent. Based on projected


                                       21

                     earnings for TBI for 1999 through 2003 and using a discount
                     rate of 14%, an acceptable discount rate considering the
                     risk-return relationship most investors would demand for an
                     investment of this type as of the valuation date, the
                     present value equaled $21.61 per share, which is below the
                     transaction value of approximately $34.30 per share.

                     Discounted Cash Flow Analysis. Hoefer & Arnett performed a
                     discounted cash flow analysis to determine hypothetical
                     present values for a share of TBI common stock as a five-
                     year investment. Under this analysis, Hoefer & Arnett
                     considered certain scenarios for the performance of TBI
                     common stock using an asset growth rate of 8.00% and a
                     return on average assets of ranging from 0.98% to 1.25%.
                     Hoefer & Arnett used a multiple of 2.16 times book value as
                     a terminal value for TBI common stock and 17.26 times
                     earnings as a terminal value for TBI common stock. A
                     discount rate of 14% was applied to these growth and
                     terminal value scenarios. This discount rate, growth rate
                     and terminal values were chosen based upon what Hoefer &
                     Arnett, in its judgment, considered to be appropriate
                     taking into account, among other things, TBI's past and
                     present performance, the general level of inflation, rates
                     of return for fixed income and equity securities in the
                     marketplace generally and for companies with similar risk
                     profiles. Using a terminal value of 2.16 times book value,
                     the present value of TBI common stock equaled $29.24 per
                     share. Using a terminal value of 17.26 times earnings, the
                     present value of TBI common stock equaled $36.40 per share.
                     The average of these present value figures is less than
                     that of the Wells Fargo offer. Thus, Hoefer & Arnett's
                     discounted cash flow analysis indicated that TBI
                     shareholders would be in a better financial position by
                     receiving the consideration offered in the merger
                     transaction rather than continuing to hold TBI common
                     stock.

                     Stock Trading History. Hoefer & Arnett reviewed and
                     analyzed the historical trading prices and volumes for
                     Wells Fargo common stock on a monthly basis from January
                     31, 1998 to May 26, 1999. The Wells Fargo common stock
                     price has ranged from a low of $24.60 to a high of $44.875.
                     The stock price to trailing 12 months earnings per share
                     has ranged from a low of 18.8 to a high of 33.5, with an
                     average of 26.37. The stock price to book value has ranged
                     from a low of 1.89 to a high of 4.20, with an average of
                     2.82. The volume of shares traded during a one-month period
                     has ranged from 4,792,500 to 94,360,900 indicating an
                     active market for Wells Fargo common stock.

                     Other Analysis. Hoefer & Arnett also reviewed selected
                     investment research reports on and earnings estimates for
                     Wells Fargo. In addition, Hoefer & Arnett prepared an
                     overview of historical financial performance of both TBI
                     and Wells Fargo.

                            The opinion expressed by Hoefer & Arnett was based
                            upon market, economic and other relevant
                            considerations as they existed and have been
                            evaluated as of the date of the opinion. Events
                            occurring after the date of issuance of the opinion,
                            including but not limited to, changes affecting the
                            securities markets, the results of operations or
                            material changes in the assets or liabilities of TBI
                            could materially affect the assumptions used in
                            preparing the opinion.

                            Financial Advisory Fees. Pursuant to an engagement
                            letter dated April 9, 1999, TBI engaged Hoefer &
                            Arnett to review the terms of the transaction and to
                            render a fairness opinion in connection with the
                            merger for $50,000 including all out-of-pocket
                            expenses.


        Additional          Certain members of TBI's management, including all
      Interests Of          its directors, have interests TBI Management in the
               TBI          merger that are in addition to their interests as
        Management          shareholders of TBI generally. TBI's board of
                            directors was aware of these interests and
                            considered them, among other things, when it
                            approved the merger agreement.

         Dissenters'        of appraisal") refer to the right Rights of
             Rights         shareholders who disagree with a particular
                            corporate action to receive the cash value of their
                            shares in lieu of whatever payment is called for by
                            that corporate action. Under the TBCA, you have this
                            right in connection with the merger. As a result, in
                            lieu of receiving shares of Wells Fargo common
                            stock, you may elect to receive the cash value of
                            your shares of TBI common stock. The value of your
                            shares will be measured as of the day immediately
                            before the special meeting, excluding any increase
                            or decrease in value in anticipation of the merger.

         Exercising         You must take a number of specific steps to exercise
         Dissenters'        your appraisal rights. Failure Rights to take these
                            steps strictly in the manner required will result in
                            you losing your appraisal rights. If you lose your
                            appraisal rights, you will be bound by the merger
                            and will receive shares of Wells Fargo common stock
                            for your shares of TBI common stock.

                            Before the meeting, you must deliver or mail written
                            notice to TBI of

                            your intent to exercise your right to dissent if the
                            merger is completed. Your notice must give an
                            address where TBI can notify you if the merger is
                            completed. Also, you must not vote any of your TBI
                            shares in favor of the merger. Simply voting against
                            the merger, however, is not sufficient to exercise
                            your appraisal rights. You must also notify TBI as
                            mentioned above and take the other steps described
                            below.

                            If TBI's shareholders approve the merger and you
                            have taken the required steps before the meeting,
                            TBI will deliver or mail written notice to you of
                            completion of the merger within 10 days after the
                            effective time of the merger. You will have 10 days
                            after delivery or mailing of this notice to you to
                            make a written demand on TBI, as the surviving
                            company in the merger, for payment of the fair value
                            of your TBI shares. You must state in your demand
                            the number of shares of TBI common stock you own and
                            your estimate of the fair value of your shares.
                            Within 20 days after demanding payment for your
                            shares, you must submit all of your share
                            certificates to TBI so that TBI can note your demand
                            on the share certificates.

                            You will lose your appraisal rights if you fail to
                            demand payment for your shares within the required
                            10-day period. Also, if you fail to submit your
                            share certificates within the required 20-day
                            period, TBI has the option to terminate your
                            appraisal rights, unless a court of competent
                            jurisdiction for good and sufficient cause otherwise
                            directs.

    Determining The         Within 20 days after TBI receives your demand for
      Fair Value of         payment, it will deliver or mail Of Your TBI Shares
    your TBI Shares         notice to you indicating whether it accepts your
                            estimate of the fair value of your shares. If TBI
                            accepts your estimate, it will pay this amount
                            within 90 days after the date the merger is
                            completed, upon surrender of your duly endorsed
                            share certificates. If TBI does not accept your
                            estimate, it will state in the notice its estimated
                            fair value of your shares. You will have 60 days
                            after completion of the merger to accept TBI's
                            estimated value. If you do, TBI will pay this amount
                            to you within 90 days after completion of the
                            merger, upon surrender of your duly endorsed share
                            certificates. Upon payment to you of the agreed
                            value, whether based on your estimate or TBI's
                            estimate, you will cease to have any interest in
                            your shares or in TBI.

                            If you do not agree with TBI's estimate of the fair
                            value of your shares, then either you or TBI may
                            file a petition in any court of competent
                            jurisdiction in Bexar County, Texas, asking the
                            court to determine the fair value of your shares.
                            The petition must be filed within 120 days after
                            completion of the merger. The court will notify by
                            registered mail all shareholders who have demanded
                            payment for their shares and who have been unable to
                            reach an agreement with TBI as to the fair value of


                                       26
<PAGE>

                            their shares. The court's notice will state the time
                            and place of the hearing at which the court will
                            consider the petition.

                            The court will appoint one or more appraisers to
                            determine the value of the TBI common stock. The
                            appraisers may examine the books and records of TBI
                            and conduct such other investigation as they deem
                            proper. The appraisers must afford a reasonable
                            opportunity to the interested parties to submit
                            pertinent evidence as to the value of the shares.
                            The appraisers will then determine the fair value of
                            the shares and report this value to the office of
                            the clerk of the court. The clerk of the court will
                            notify all parties of this value. After hearing any
                            legal or factual exceptions to the report, the court
                            will then determine the fair value of the shares and
                            direct TBI to pay that value, together with interest
                            for the period beginning 91 days after the effective
                            time of the merger and ending on the date of the
                            court's judgment, to the shareholders entitled to
                            payment, upon surrender of their duly endorsed share
                            certificates. The court's determination of the value
                            of the TBI common stock will be binding on TBI and
                            all shareholders who have been so notified. Upon
                            payment of this amount, dissenting shareholders will
                            cease to have any interest in their shares or in
                            TBI. The court allows the appraisers a reasonable
                            fee as court costs, and all court costs are allotted
                            between the parties in a manner that the court
                            determines is fair and equitable.

             Demand         before payment for your shares For Payment and
            Payment         before any petition is filed seeking a determination
                            of the fair value of the shares. With TBI's consent,
                            you may withdraw your demand after the petition is
                            filed.

                            If you are presumed to have approved the merger, you
                            will be bound by the merger and will cease to have
                            any rights in the shares or in TBI. Upon surrender
                            of your duly endorsed certificates for your shares

                            certificates for TBI common stock are presented for
                            transfer to the exchange agent, they will be
                            canceled and exchanged for certificates representing
                            Wells Fargo common stock.

                            faith to a public official pursuant to applicable

         Regulatory         The merger is subject to the prior approval of the
          Approvals         Board of Governors of the Federal Reserve System.
                            The approval of the Federal Reserve Board is
                            required because Wells Fargo is a bank holding
                            company registered under the Bank Holding Company
                            Act. On July 15, 1999, Wells Fargo filed an
                            application with the Federal Reserve Board
                            requesting approval of the merger. The Federal
                            Reserve Board has notified Wells Fargo that it
                            expects to act on Wells Fargo's application by
                            September 16, 1999. In order to receive Federal
                            Reserve Board approval, Wells Fargo has proposed to
                            sell all of the loans and substantially all of the
                            deposits held by the Pleasanton, Texas branch of
                            First National Bank of South Texas. At July 31,
                            1999, the Pleasanton, Texas branch had approximately
                            $13.95 million of deposits and $5.26 million of
                            loans.

                            The merger is also subject to certain filing and
                            other requirements of the Texas Department of
                            Banking. On July 22, 1999, Wells Fargo filed the
                            required notice of merger with the Texas Department
                            of Banking.

                            The approval of an application means only that the
                            regulatory criteria for approval have been satisfied
                            or waived. It does not mean that the approving
                            authority has determined that the consideration to
                            be received by TBI shareholders is fair. Regulatory
                            approval does not constitute an endorsement or
                            recommendation of the merger.

                            Wells Fargo and TBI 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. Wells Fargo and TBI intend to seek
                            any other approval and to take any other action that
                            may be required to effect the merger. There can be
                            no assurance that any required approval or action
                            can be obtained or taken prior to the special
                            meeting.

                            The merger cannot be completed unless all necessary
                            regulatory approvals are granted. In addition, Wells
                            Fargo may elect not to complete the merger if any
                            condition under which any regulatory approval is
                            granted is unreasonably burdensome to Wells Fargo.

                     "--Termination Of The Merger Agreement."

         Effect of   The merger agreement provides that, subject to any
         Merger On   eligibility requirements Employee applicable to such plans,
             TBI's   of TBI will be entitled to participate in those Wells Fargo
          Employee   employee benefit and welfare plans specified in the merger
     Benefit Plans   agreement. Eligible employees of TBI will enter each of
                     such plans no later than the first day of the calendar
                     quarter which begins at least 32 days after completion of
                     the merger.

      U.S. Federal   The following is a summary of the anticipated material U.S.
        Income Tax   federal income tax employees consequences of the merger to
      Consequences   shareholders who are citizens or residents of the
     Of The Merger   United States and who, on the date of disposition of their
                     shares of TBI common stock, hold such shares as capital
                     assets. This summary does not purport to deal with all
                     aspects of taxation that may be relevant to particular
                     investors in light of their personal investment
                     circumstances, or to certain types of investors, including
                     insurance companies, tax-exempt organizations, financial
                     institutions, broker-dealers, "S" corporations, limited
                     liability corporations, foreign corporations and taxpayers
                     subject to alternative minimum tax.

                     The summary is based on the U.S. federal income tax laws as
                     currently in effect and as currently interpreted. It does
                     not cover issues of state, local or foreign taxation. Nor
                     does it address all aspects of U.S. federal income taxation
                     that may be important to particular shareholders in light
                     of their personal circumstances or to shareholders subject
                     to special rules under U.S. federal income tax laws. Future
                     legislation, regulations, administrative rulings and court
                     decisions may alter the tax consequences summarized below.

                     The summary does not address the tax consequences to the
                     holders of TBI options who, in connection with the merger,
                     exercise their options or receive cash upon redemption of
                     their options by TBI.

                     The anticipated U.S. federal income tax consequences to TBI
                     shareholders are as follows:

                     .   A shareholder who receives shares of Wells Fargo common
                         stock in exchange for shares of TBI common stock will
                         not recognize any gain or loss on the receipt of the
                         shares of Wells Fargo common stock, except for cash
                         received in lieu of a fractional share. The
                         shareholder's gain or loss on the receipt of cash in
                         lieu of a fractional share will equal the difference
                         between the cash received and the basis of the
                         fractional share exchanged.

                                       30
<PAGE>

                     .   A shareholder's tax basis in the shares of Wells Fargo
                         common stock received will be the same as the
                         shareholder's tax basis in the shares of TBI common
                         stock exchanged in the merger, less any cash received
                         in lieu of fractional shares.

                     .   The holding period of the shares of Wells Fargo common
                         stock received by a shareholder will include the
                         holding period of the shareholder's shares of TBI
                         common stock exchanged in the merger, but only if the
                         shares of TBI common stock were held as a capital asset
                         at the time the merger is completed.

                     TBI is not required to complete the merger unless it
                     receives an opinion of KPMG LLP that these will be the U.S.
                     federal income tax consequences of the merger. The opinion
                     may make certain assumptions and may rely on
                     representations of the parties to the merger as to factual
                     matters. It will reflect KPMG's judgment as to the tax
                     status of the merger under the Code and will not be binding
                     on the IRS. There is no assurance that the IRS will not
                     take a contrary position regarding the tax consequences of
                     the merger, nor is there any assurance that the IRS would
                     not prevail in the event the tax consequences of the merger
                     were litigated.

                     The U.S. Federal income tax summary set forth above is
                     included for general information only and may or may not be
                     applicable depending upon a shareholder's particular
                     situation. Shareholders should consult their tax advisors
                     with respect to the tax consequences to them of the merger,
                     including the tax consequences under state, local, foreign
                     and other tax laws and the possible effects of changes in
                     federal or other tax law. TBI option holders should consult
                     their tax advisers as to the consequences of exercising
                     their options or receiving cash upon redemption of their
                     options by TBI.

         Resale Of   The Wells Fargo common stock issued in the merger will be
       Wells Fargo   freely transferable under the Securities Act of 1933,
            Common   except for shares issued to TBI shareholders who are
      Stock Issued   considered to be "affiliates" of TBI or Wells Fargo under
     In The Merger   Rule 145 under the Securities Act or of Wells Fargo under
                     Rule 144 under the Securities Act. The definition of
                     "affiliate" is complex and depends on the specific facts,
                     but generally includes directors, executive officers, 10%
                     stockholders and other persons with the power to direct the
                     management and policies of the company in question.

                     Affiliates of TBI may not sell the shares of Wells Fargo
                     common stock received in the merger except (a) pursuant to
                     an effective registration statement under the Securities
                     Act, (b) in compliance with an exemption from the
                     registration requirements of the Securities Act or (c) in

                                       31

                     compliance with Rule 144 and Rule 145 under the Securities
                     Act. Generally, those rules permit resales of stock
                     received by affiliates so long as Wells Fargo has complied
                     with certain reporting requirements and the selling
                     stockholder complies with certain volume and manner of sale
                     restrictions.

                     TBI has agreed to use its best efforts to deliver to Wells
                     Fargo signed representations by each person who may be
                     deemed to be an affiliate of TBI that the person will not
                     sell, transfer or otherwise dispose of the shares of Wells
                     Fargo common stock to be received by the person in the
                     merger except in compliance with the applicable provisions
                     of the Securities Act and the rules and regulations
                     promulgated thereunder.

                     This proxy statement-prospectus does not cover any resales
                     of Wells Fargo common stock received by affiliates of TBI.


          Stock      The shares of Wells Fargo common stock to be issued in the
       Exchange      merger will be listed on the New York Stock Exchange and
        Listing      the Chicago Stock Exchange.

     Accounting      Wells Fargo will account for the merger as a purchase.
      Treatment      Wells Fargo will record, at fair value, the acquired assets
                     and assumed liabilities of TBI. To the extent the total
                     purchase price exceeds the fair value of the assets
                     acquired and liabilities assumed, Wells Fargo will record
                     goodwill. Wells Fargo will include in its results of
                     operations the results of TBI's operations after the
                     merger.

                     The unaudited pro forma data included in this proxy
                     statement-prospectus for the merger have been prepared

The Merger Agreement
- -------------------------------------------------------------------------------

The following is a summary of certain provisions of the merger agreement, a copy
of which is attached to this proxy statement-prospectus as Appendix A. The
merger agreement is incorporated by reference into this proxy statement-
prospectus. This summary is qualified in its entirety by reference to the full
text of the merger agreement. TBI shareholders are encouraged to read the merger
agreement carefully and in its entirety. Parenthetical references are to the
relevant paragraph or paragraphs of the merger agreement.

- --------------------------------------------------------------------------------

      Basic Plan Of  The merger agreement provides that a wholly-owned
     Reorganization  subsidiary of Wells Fargo will merge by statutory merger
                     with and into TBI, with TBI as the surviving corporation.
                     (paragraph 1(a))

   Exchange Of TBI   In the merger, each share of TBI common stock outstanding
  Shares For Wells   immediately before the merger, other than shares as to
      Fargo Shares   which dissenters' rights are exercised, will be exchanged
                     for the number of shares of Wells Fargo common stock
                     determined by dividing the Adjusted Wells Fargo Shares by
                     the number of shares of TBI common stock then outstanding.
                     (paragraph 1(a)(i))

                     .   The number of Adjusted Wells Fargo Shares will equal
                         the Aggregate Share Amount divided by the Wells Fargo
                         Measurement Price.

                     .   The Aggregate Share Amount will equal $68,500,000 plus
                         the aggregate exercise price of all Options exercised
                         by cash payments between the date of the merger
                         agreement and the day immediately before the closing
                         date of the merger minus the Cash Surrender Amount.

                     .   The Cash Surrender Amount will equal the difference
                         between (i) the product of (A) the Fair Market Value
                         Per Share multiplied by (B) the number of Redeemed
                         Options minus (ii) the aggregate exercise price of all
                         Redeemed Options.

                     .   Fair Market Value Per Share is $34.2988.

                     .   Option means any option issued under the 1996 Texas
                         Bancshares, Inc. Stock Option Plan, as amended as of
                         October 20, 1997.

                     .   Redeemed Option means any Option redeemed by TBI
                         pursuant to paragraph 4(q) of the merger agreement.

                                       33
<PAGE>

                     .   The Wells Fargo Measurement Price will equal the
                         average of the closing prices of a share of Wells Fargo
                         common stock as reported on the consolidated tape of
                         the New York Stock Exchange during the period of 10
                         trading days ending on the day immediately before the
                         special meeting of TBI shareholders.

                     The price of Wells Fargo common stock on the effective date
                     of the merger may be higher or lower than the Wells Fargo
                     Measurement Price. No adjustment will be made to the number
                     of shares of Wells Fargo common stock you will receive to
                     reflect fluctuations in the price of Wells Fargo common
                     stock occurring after the special meeting.

    Redemption Of    TBI has also agreed to redeem for cash all that have not
  Unexercised TBI    been exercised as of TBI Options immediately before the
          Options    merger. The redemption price for each Option share will
                     equal the Fair Market Value Per Share minus the exercise
                     price of the Option share. (paragraph 4(q))

  Cash In Lieu Of    If the aggregate number of shares of Wells Fargo common
Fractional Shares    stock you will receive in the Shares merger does not equal
                     a whole number, you will receive cash in lieu of the
                     fractional share. The cash payment will be equal to the
                     product of the fractional part of the share of Wells Fargo
                     common stock multiplied by the Wells Fargo Measurement
                     Price. (paragraph 1(c))

   Effective Date    The effective date of the merger will be the day on which
  And Time Of The    articles of merger are The Merger filed with and accepted
           Merger    by the Texas Secretary of State. The merger agreement
                     provides that articles of merger will be filed within 10
                     business days after the satisfaction or waiver of all
                     conditions to the merger or such other date as Wells Fargo
                     and TBI may agree. The effective time of the merger will be
                     11:59 p.m., Austin, Texas time, on the effective date of
                     the merger. (paragraph 1(d))

       Represent-    The merger agreement contains various representations and
       ations And    warranties by Wells Fargo Warranties and TBI concerning (a)
         Warrants    their organization and legal authority to engage in their
                     respective businesses; (b) their capitalization; (c) their
                     corporate authority to enter into the merger agreement and
                     complete the merger, (d) the absence of certain material
                     changes; (e) compliance with laws; (f) material contracts;
                     (g) absence of certain litigation; and (h) undisclosed
                     liabilities. (paragraphs 2 and 3) Because the
                     representations and warranties do not survive completion of

         Covenants   agreements that govern the actions of TBI and Wells Fargo
                     pending completion of the merger. Some of the covenants and

                     options that, as of immediately before the merger, have not
                     been exercised. See "Basic Plan Of Reorganization" above

                  Agreement    TBI can agree to terminate the merger agreement

                               (paragraph 9(a)(i))

                               Termination by Either Wells Fargo or TBI. Either
                               Wells Fargo or TBI can terminate the merger

                                      February 29, 2000, unless the failure to
                                      complete the merger is due to the failure
                                      of the party seeking to terminate to
                                      perform or observe in all material

                                      order restraining, enjoining or otherwise
                                      prohibiting the transactions contemplated
                                      by the merger agreement. (paragraph
                                      9(a)(iii))


       Effect Of Termination   Generally, if either party terminates the merger
                               agreement, it becomes void without any liability
                               to either party other than for willful and
                               material breaches occurring before termination;
                               however, the provisions of the merger agreement
                               governing confidential information and expenses
                               incurred in connection with the merger continue
                               in effect after termination of the merger
                               agreement. (paragraph 9(b))


      Waiver And Amendment     Either Wells Fargo or TBI may waive any
                               inaccuracies in the representations and
                               warranties of the other party or compliance by
                               the other party with any of the covenants or
                               conditions contained in the merger agreement.
                               (paragraph 16)

                               Wells Fargo and TBI can amend the merger
                               agreement at any time before the merger is
                               completed; however, the merger agreement
                               prohibits them from amending the merger agreement
                               after TBI shareholders approve the merger if the
                               amendment would change in a manner adverse to TBI
                               shareholders the consideration to be received by
                               TBI shareholders in the merger. (paragraph 17)

                               auditors and counsel. (paragraph 10)

                Rights Plan    Wells Fargo. Each share of Wells Fargo common
                               stock (including shares that will be issued in
                               the merger) has attached to it one preferred
                               share purchase right. Once exercisable, each
                               right allows the holder to purchase a fractional
                               share of Wells Fargo's Series C Junior
                               Participating Preferred Stock. A right, by
                               itself, does not confer on its holder any rights
                               of a Wells Fargo stockholder, including the right
                               to vote or receive dividends, until the right is
                               exercised. The rights trade automatically with
                               shares of Wells Fargo common stock. The rights
                               are designed to protect the interests of Wells
                               Fargo and its stockholders against coercive
                               takeover tactics. The rights are intended to
                               encourage potential acquirors to negotiate on

                               proposed takeover. Although not their purpose,
                               the rights may deter takeover proposals.

                               serving a term of one year or until his or her
                               earlier death, resignation or removal. The number
                               of directors of Wells Fargo is currently fixed at
                               24. Directors of Wells Fargo may be removed with
                               or without cause by the affirmative vote of the
                               holders of a majority of the shares of Wells
                               Fargo capital stock entitled to vote thereon.
                               Vacancies on Wells Fargo's board of directors may
                               be filled by majority vote of the remaining
                               directors or, in the event a vacancy is not so
                               filled or if no director remains, by the
                               stockholders. Directors of Wells Fargo are
                               elected by plurality of the votes of shares of
                               Wells Fargo capital stock entitled to vote
                               thereon present in person or by proxy at the
                               meeting at which directors are elected. Wells
                               Fargo's restated certificate of incorporation
                               does not currently permit cumulative voting in
                               the election of directors.

                               TBI. TBI's bylaws provide that the number of
                               directors composing the initial board of
                               directors is fixed at 10 and that such number of
                               directors may be increased or decreased upon
                               resolution of the board of directors. TBI's board
                               of directors, by resolution, has fixed the number
                               of directors at eight. Each director is elected
                               annually and serves until the next annual meeting
                               and until the director's successor is elected and
                               qualified. Cumulative voting is not permitted for
                               the election of directors. At any meeting of
                               shareholders called expressly for the purpose of
                               removal, directors of TBI may be removed, with or
                               without cause, by a vote of the holders of a
                               majority of the shares entitled to vote for the
                               election of such directors. Vacancies on the
                               board of directors may be filled by the
                               affirmative vote of a majority of the remaining
                               directors, but any vacancy to be filled by reason
                               of an increase in the

                               number of directors must be filled by election of
                               the shareholders of TBI. TBI's bylaws also
                               provide that the board of directors may from time
                               to time elect any number of advisory directors as
                               determined to be appropriate, who are elected to
                               the same term of office as the regular directors
                               unless otherwise determined by the board of
                               directors. Advisory directors do not have voting
                               rights. Currently, there are three advisory
                               directors of TBI.


     Amendment Of Governing    Wells Fargo.  Wells Fargo's restated certificate
                  Documents    of incorporation may be amended only if the
                               proposed amendment is approved by Wells Fargo's
                               board of directors and thereafter approved by a
                               majority of the outstanding stock entitled to
                               vote thereon and by a majority of the outstanding
                               stock of each class entitled to vote thereon as a
                               class. Wells Fargo's bylaws may be amended by a
                               majority of Wells Fargo's board of directors or
                               by a majority of the outstanding stock entitled
                               to vote thereon. Shares of Wells Fargo preferred
                               stock and Wells Fargo preference stock currently
                               authorized in Wells Fargo's restated certificate
                               of incorporation may be issued by Wells Fargo's
                               board of directors without amending Wells Fargo's
                               restated certificate of incorporation or
                               otherwise obtaining the approval of Wells Fargo's
                               Stockholders.

                               TBI.  Under the TBCA, amendments to TBI's
                               restated articles of incorporation require the
                               affirmative vote of the holders of at least two-
                               thirds of the outstanding shares entitled to vote
                               thereon, unless any class or series of shares is
                               entitled to vote thereon as a class, in which
                               event the proposed amendment shall be adopted
                               upon receiving the affirmative vote of the
                               holders of at least two-thirds of the shares
                               within each class or series entitled to vote
                               thereon as a class and of at least two-thirds of
                               the total outstanding shares entitled to vote
                               thereon. TBI's bylaws may be amended by a vote of
                               the majority of TBI board of directors or under
                               the TBCA by a vote of the holders of a majority
                               of the shares entitled to vote at a meeting of
                               shareholders at which a quorum is present.


    Approval Of Mergers And    Wells Fargo.  Except as described below, the
               Assets Sales    affirmative vote of a majority of the outstanding
                               shares of Wells Fargo common stock entitled to
                               vote thereon is required to approve a merger or
                               consolidation involving Wells Fargo or the sale,
                               lease or exchange of all or substantially all of
                               Wells Fargo's corporate assets. No vote of the
                               stockholders is required, however, in connection
                               with a merger in which Wells Fargo is the
                               surviving corporation and (a) the agreement of
                               merger for the mergers does not amend in any
                               respect Wells Fargo's restated certificate of
                               incorporation, (b) each share of capital stock
                               outstanding immediately before the merger is to
                               be an identical outstanding or treasury share of
                               Wells Fargo after the merger and (c) the

                                       40
<PAGE>

                               number of shares of capital stock to be issued in
                               the merger (or to be issuable upon conversion of
                               any convertible instruments to be issued in the
                               merger) does not exceed 20% of the shares of
                               Wells Fargo's capital stock outstanding
                               immediately before the merger.

                               TBI. The TBCA requires certain mergers to be
                               approved by holders of at least two-thirds of the
                               outstanding shares entitled to vote thereon (if
                               there is a class of stock that is entitled to
                               vote as a class, then the merger must be approved
                               by the holders of two-thirds of the outstanding
                               shares of each class of stock entitled to vote
                               thereon). The TBCA similarly requires that a sale
                               of all or substantially all of the assets of a
                               corporation not made in the ordinary course of
                               business be approved by the affirmative vote of
                               the holders of at least two-thirds of the
                               outstanding shares entitled to vote thereon. With
                               respect to the approval of a merger or asset
                               sale, however, the articles of incorporation may
                               require a vote of a different number, but not
                               less than a majority, of the shares outstanding.
                               TBI restated articles of incorporation do not
                               provide for a different number of shares for
                               approval of a merger or asset sale.


          Preemptive Rights    Wells Fargo. Neither Wells Fargo's restated
                               certificate of incorporation nor its bylaws
                               grants preemptive rights to its stockholders.

                               TBI. TBI restated articles of incorporation deny
                               preemptive rights to the shareholders.


           Appraisal Rights    Wells Fargo. Section 262 of the DGCL provides for
                               stockholder appraisal rights in connection with
                               consolidations and mergers generally; however,
                               appraisal rights are not available to holders of
                               any class or series of stock that, at the record
                               date fixed to determine stockholders entitled to
                               receive notice of and to vote at the meeting to
                               act upon the agreement of consolidation or
                               merger, were either (a) listed on a national
                               securities exchange or designated as a national
                               market system security on an interdealer
                               quotation system by the National Association of
                               Securities Dealers, Inc. or (b) held of record by
                               more than 2,000 stockholders, so long as
                               stockholders receive shares of the surviving
                               corporation or another corporation whose shares
                               are so listed or designated or held by more than
                               2,000 stockholders. Wells Fargo common stock is
                               listed on the New York Stock Exchange and the
                               Chicago Stock Exchange and currently held by more
                               than 2,000 stockholders. As a result, assuming
                               that the other conditions described above are
                               satisfied, holders of Wells Fargo common stock
                               will not have appraisal rights in connection with
                               consolidations and mergers involving Wells Fargo.

                               TBI. Shareholders of Texas corporations are
                               entitled to exercise certain

                               dissenters' appraisal rights in the event of a
                               sale, lease, exchange, or other disposition of
                               all, or substantially all, of the property and
                               assets of the corporation not made in the
                               ordinary course of business, and with the
                               exception discussed below, a merger or
                               consolidation. Under Article 5.11B of the TBCA,
                               however, shareholders do not have dissenters'
                               rights if, in connection with a merger, the stock
                               of the corporation held by the shareholders is
                               either listed on a national securities exchange
                               or is held of record by not less than 2,000
                               shareholders and, pursuant to the plan of merger,
                               such shareholders are not required to accept for
                               their shares any consideration other than (a)
                               shares of stock of a corporation which,
                               immediately after the effective date of the
                               merger, (i) are listed on a national securities
                               exchange, or (ii) are held of record by not less
                               than 2,000 shareholders, and (b) cash in lieu of
                               fractional shares otherwise entitled to be
                               received. Shareholders of TBI will receive merger
                               consideration that satisfies the provisions of
                               Article 5.11B described above; however, because
                               TBI common stock and TBI preferred stock are not
                               listed on a national securities exchange and are
                               held of record by fewer than 2,000 holders,
                               dissenters' appraisal rights will be available to
                               TBI shareholders. See "The Merger--Dissenters'
                               Rights."


           Special Meetings    Wells Fargo: Under the DGCL, special meetings of
                               stockholders may be called by the board of
                               directors or by such persons as may be authorized
                               in the certificate of incorporation or bylaws.
                               Wells Fargo's bylaws provide that a special
                               meeting of stockholders may be called only by the
                               chairman of the board, a vice chairman, the
                               president or a majority of Wells Fargo's board of
                               directors. Holders of Wells Fargo common stock do
                               not have the ability to call a special meeting of
                               stockholders.

                               TBI. Under the TBCA, a special meeting of
                               shareholders of a Texas corporation may be called
                               by either (a) the president, the board of
                               directors, or such other person or persons as
                               authorized by the articles of incorporation or
                               the bylaws, or (b) the holders of shares entitled
                               to cast not less than 10% of all shares entitled
                               to vote at the meeting, unless a different
                               percentage, not to exceed 50%, as provided for in
                               the articles of incorporation. TBI's restated
                               articles of incorporation and bylaws do not alter
                               the manner in which a special meeting of
                               shareholders may be called.


          Directors' Duties    Wells Fargo. The DGCL does not specifically
                               enumerate directors' duties. In addition, the
                               DGCL does not contain any provision specifying
                               what factors a director must and may consider in
                               determining a corporation's best interests.
                               However, judicial decisions in Delaware have
                               established that, in performing their duties,
                               directors are bound to

                                       42
<PAGE>

                               use that degree of care which ordinarily prudent
                               persons would use in similar circumstances.

                               TBI. The TBCA does not specifically enumerate the
                               fiduciary duties of a director. Judicial
                               decisions have established that the fiduciary
                               duties of a director include the duty of care and
                               the duty of loyalty. The duty of care requires
                               directors to exercise reasonable care in
                               performing duties, to be diligent and prudent,
                               and to inform themselves in making decisions and
                               managing the corporation's affairs. The duty of
                               loyalty requires directors to act in good faith
                               and not allow personal interests to prevail over
                               the interests of the corporation and the
                               shareholders.


   Action Without A Meeting    Wells Fargo. As permitted by Section 228 of the
                               DGCL and Wells Fargo's restated certificate of
                               incorporation, any action required or permitted
                               to be taken at a stockholders' meeting may be
                               taken without a meeting pursuant to the written
                               consent of the holders of the number of shares
                               that would have been required to effect the
                               action at an actual meeting of the stockholders.

                               TBI. Under the TBCA, shareholders may act without
                               a meeting if a consent in writing to such action
                               is signed by all shareholders. However, the TBCA
                               also allows the articles of incorporation to
                               provide that any action required or permitted to
                               be taken at a shareholders' meeting may be taken
                               without a meeting pursuant to the written consent
                               of the holders of not less than the number of
                               shares that would have been required to effect
                               the action at an actual meeting of the
                               shareholders. TBI restated articles of
                               incorporation contain a provision permitting
                               actions to be taken by the shareholders by a
                               written consent of the holders of shares having
                               not less than the minimum number of votes that
                               would be necessary to take such action at a
                               meeting at which the holders of all shares
                               entitled to vote on the action were present and
                               voted.


  Limitations On Directors'    Wells Fargo. Wells Fargo's restated certificate
                  Liability    of incorporation provides that a director
                               (including an officer who is also a director) of
                               Wells Fargo shall not be liable personally to
                               Wells Fargo or its stockholders for monetary
                               damages for breach of fiduciary duty as a
                               director, except for liability arising out of (a)
                               any breach of the director's duty of loyalty to
                               Wells Fargo or its stockholders, (b) acts or
                               omissions not in good faith or which involve
                               intentional misconduct or a knowing violation of
                               law, (c) payment of a dividend or approval of a
                               stock repurchase in violation of Section 174 of
                               the DGCL or (d) any transaction from which the
                               director derived an improper personal benefit.
                               This provision protects Wells Fargo's directors
                               against personal liability for monetary damages
                               from breaches of their duty of care. It does not
                               eliminate the director's duty of care and has no
                               effect on the

                                       43
<PAGE>

                         availability of equitable remedies, such as an
                         injunction or rescission, based upon a director's
                         breach of his duty of care.

                         TBI. The Texas Miscellaneous Corporations Laws Act
                         (TMCLA) permits a corporation's articles of
                         incorporation to set limits on the extent of a
                         director's liability except liability for monetary
                         damages cannot be eliminated for: (a) a breach of duty
                         of loyalty to the corporation or its shareholders, (b)
                         an act or omission not in good faith that constitutes a
                         breach of duty to the corporation or an act or omission
                         that involves intentional misconduct or a knowing
                         violation of law, (c) a transaction from which the
                         director receives an improper benefit, whether or not
                         the benefit resulted from an action taken within the
                         scope of the director's office, and (d) an act or
                         omission for which liability is expressly provided for
                         by statute. TBI's restated articles of incorporation
                         contain provisions limiting an advisory director's and
                         a director's liability consistent with the TMCLA and
                         contain a provision that if the TBCA or TMCLA is
                         amended to authorize further limitation of the
                         liability of directors and advisory directors, then the
                         liability of such persons shall be limited to the
                         fullest extent permitted by the TBCA and the TMCLA,
                         each as amended.


     Indemnification Of  Wells Fargo. Wells Fargo's restated certificate of
           Officers And  incorporation provides that Wells Fargo must indemnify,
              Directors  to the fullest extent authorized by the DGCL, each
                         person who was or is made a party to, is threatened to
                         be made a party to, or is involved in, any action,
                         suit, or proceeding because he is or was a director or
                         officer of Wells Fargo (or was serving at the request
                         of Wells Fargo as a director, trustee, officer,
                         employee, or agent of another entity) while serving in
                         such capacity against all expenses, liabilities, or
                         loss incurred by such person in connection therewith,
                         provided that indemnification in connection with a
                         proceeding brought by such person will be permitted
                         only if the proceeding was authorized by Wells Fargo's
                         board of directors. Wells Fargo's restated certificate
                         of incorporation also provides that Wells Fargo must
                         pay expenses incurred in defending the proceedings
                         specified above in advance of their final disposition,
                         provided that if so required by the DGCL, such advance
                         payments for expenses incurred by a director or officer
                         may be made only if he undertakes to repay all amounts
                         so advanced if it is ultimately determined that the
                         person receiving such payments is not entitled to be
                         indemnified. Wells Fargo's restated certificate of
                         incorporation authorizes Wells Fargo to provide similar
                         indemnification to employees or agents of Wells Fargo.

                         Pursuant to Wells Fargo's restated certificate of
                         incorporation, Wells Fargo may maintain insurance, at
                         its expense, to protect itself and any directors,
                         officers, employees or agents of Wells Fargo or another
                         entity against any expense, liability or loss,
                         regardless of whether Wells Fargo

                                       44
<PAGE>

                         has the power or obligation to indemnify that person
                         against such expense, liability or loss under the DGCL.

                         The right to indemnification is not exclusive of any
                         other right which any person may have or acquire under
                         any statute, provision of Wells Fargo's restated
                         certificate of incorporation or Wells Fargo bylaws,
                         agreement, vote of stockholders or disinterested
                         directors or otherwise.

                         TBI. TBI's articles of incorporation provide that TBI,
                         by action of its board of directors, may indemnify any
                         director or officer of TBI, or any person who may have
                         served at the request of TBI as a director or officer
                         of another corporation in which it owns shares or of
                         which it is a creditor, against any costs and expenses
                         including counsel fees, actually and necessarily
                         incurred (or reasonably expected to be incurred) in
                         connection with the defense of any civil criminal,
                         administrative or other claim, action, suit or
                         proceeding (whether by or in the right of TBI or
                         otherwise) in which the person may become involved or
                         with which the person may be threatened, by reason of
                         the person being or having been such a director or
                         officer, and against any payments in settlement of such
                         claim, action, suit or proceeding or in satisfaction of
                         any related judgment, fine or penalty, provided that
                         the board of directors shall, in the exercise of its
                         business judgment, determine that such indemnification
                         is in the best interests of TBI. TBI's bylaws provide
                         that TBI shall indemnify its directors and officers
                         from and against any and all liabilities, costs and
                         expenses incurred by them in such capacities as and to
                         the fullest extent permitted by the TBCA and that TBI
                         shall pay their expenses in defending an action, suit
                         or proceeding in advance of its final disposition.

                         The TBCA provides that a corporation may indemnify a
                         director or officer who was, is or is threatened to be
                         made a named defendant or respondent in a proceeding
                         because the person is or was a director or officer if
                         such person: (a) conducted himself in good faith; (b)
                         reasonably believed: (i) in the case of conduct in his
                         official capacity as a director or officer, that his
                         conduct was in the corporation's best interests and
                         (ii) in all other cases, that his conduct was at least
                         not opposed to the corporation's best interests; and
                         (c) in the case of any criminal proceeding, had no
                         reasonable cause to believe his conduct was unlawful.
                         The TBCA also provides that a corporation must
                         indemnify a director or officer against reasonable
                         expenses incurred by him in connection with a
                         proceeding in which such person is a named defendant or
                         respondent because he is or was a director or officer
                         if he has been wholly successful, on the merits or
                         otherwise, in the defense of the proceeding. Certain
                         other individuals serving at the request of the
                         corporation may also be indemnified under Texas law.

              Dividends  Wells Fargo. Delaware corporations may pay dividends
                         out of surplus or, if there is no surplus, out of net
                         profits for the fiscal year in which declared and for
                         the preceding fiscal year. Section 170 of the DGCL also
                         provides that dividends may not be paid out of net

                         is less than the capital represented by the outstanding
                         stock of all classes having a preference upon the
                         distribution of assets. Wells Fargo is also subject to
                         Federal Reserve Board policies regarding payment of
                         dividends, which generally limit dividends to operating
                         earnings. See "Regulation And Supervision Of Wells

Information About Wells Fargo
- --------------------------------------------------------------------------------

                General  Wells Fargo is a diversified financial services
                         company. Through its subsidiaries and affiliates, Wells
                         Fargo provides retail, commercial, real estate and
                         mortgage banking, asset management and consumer
                         finance, as well as a variety of other financial
                         services, including equipment leasing, agricultural
                         finance, securities brokerage and investment banking,
                         insurance agency services, computer and data processing
                         services, trust services, mortgage-backed securities
                         servicing, and venture capital investment.

                         At June 30, 1999, Wells Fargo had consolidated total
                         assets of $205 billion, consolidated total deposits of
                         $133 billion and stockholders' equity of $21 billion.
                         Based on assets at June 30, 1999, Wells Fargo was the
                         7th largest commercial banking organization in the
                         United States.

                         Wells Fargo expands its business in part by acquiring
                         banking institutions and other companies engaged in
                         activities closely related to banking. Wells Fargo
                         continues to explore opportunities to acquire banking
                         institutions and other companies permitted by the Bank
                         Holding Company Act of 1956. Discussions are
                         continually being carried on related to such
                         acquisitions. It is not presently known whether, or on
                         what terms, such discussions will result in further
                         acquisitions. It is the policy of Wells Fargo not to
                         comment on such discussions or possible acquisitions
                         until a definitive agreement with respect thereto has
                         been signed.

                         Wells Fargo is a legal entity separate and distinct
                         from its banking and nonbanking subsidiaries. As a
                         result, the right of Wells Fargo--and thus the right of
                         Wells Fargo's creditors--to participate in any
                         distribution of assets or earnings of any subsidiary,
                         other than in its capacity as a creditor of such
                         subsidiary, is subject to the prior payment of claims
                         of creditors of such subsidiary. The principal sources
                         of Wells Fargo's revenues are dividends and fees from
                         its subsidiaries. See "Regulation And Supervision Of
                         Wells Fargo--Dividend Restrictions" for a discussion of

                         pay dividends to Wells Fargo.

Regulation And Supervision Of Wells Fargo
- --------------------------------------------------------------------------------

To the extent that the following information describes statutory and regulatory
provisions, it is qualified in its entirety by reference to the full text of
those provisions. Also, such statutes, regulations and policies are continually
under review by Congress and state legislatures and federal and state regulatory
agencies. A change in statutes, regulations or regulatory policies applicable to
Wells Fargo could have a material effect on the business of Wells Fargo.

- --------------------------------------------------------------------------------



              General    Wells Fargo, its banking subsidiaries and many of its
                         nonbanking subsidiaries are subject to extensive
                         regulation by federal and state agencies. The
                         regulation of bank holding companies and their
                         subsidiaries is intended primarily for the protection
                         of depositors, federal deposit insurance funds and the
                         banking system as a whole and not for the protection of
                         security holders.

                         As discussed in more detail below, this regulatory
                         environment, among other things, may restrict Wells
                         Fargo's ability to diversify into certain areas of
                         financial services, acquire depository institutions in
                         certain states and pay dividends on its capital stock.
                         It may also require Wells Fargo to provide financial
                         support to one or more of its banking subsidiaries,
                         maintain capital balances in excess of those desired by
                         management and pay higher deposit insurance premiums as
                         a result of the deterioration in the financial
                         condition of depository institutions in general.


             Regulatory  Agencies Bank Holding Company. Wells Fargo & Company, a
               Agencies  bank holding company, is subject to regulation under
                         the Bank Holding Company Act of 1956 and to inspection,
                         examination and supervision by the Board of Governors
                         of the Federal Reserve System (Federal Reserve Board)
                         under the Bank Holding Company Act of 1956.

                         Subsidiary Banks. Wells Fargo's national banking
                         subsidiaries are subject to regulation and examination
                         primarily by the Office of the Comptroller of the
                         Currency (OCC) and secondarily by the Federal Reserve
                         Board and the Federal Deposit Insurance Corporation
                         (FDIC). Wells Fargo's state-chartered banking
                         subsidiaries are subject to primary federal regulation
                         and examination by the FDIC or the Federal Reserve
                         Board and, in addition, are regulated and examined by
                         their respective state banking departments.

                         Nonbank Subsidiaries. Many of Wells Fargo's nonbank
                         subsidiaries also are subject to regulation by the
                         Federal Reserve Board and other

                                       49

                         applicable federal and state agencies. Wells Fargo's
                         brokerage subsidiaries are regulated by the SEC, the
                         National Association of Securities Dealers, Inc. and
                         state securities regulators. Wells Fargo's insurance
                         subsidiaries are subject to regulation by applicable
                         state insurance regulatory agencies. Other nonbank
                         subsidiaries of Wells Fargo are subject to the laws and
                         regulations of both the federal government and the
                         various states in which they conduct business.

          Bank Holding   Banking-Related Requirement. Under the Bank Holding
               Company   Company Act, bank holding companies generally may not
            Activities   acquire the beneficial ownership or control of more
                         than 5% of the voting shares or substantially all of
                         the assets of any company, including a bank, without
                         the Federal Reserve Board's prior approval. Also, bank
                         holding companies generally may engage, directly or
                         indirectly, only in banking and such other activities
                         as the Federal Reserve Board determines to be closely
                         related to banking.

                         Interstate Banking. Under the Riegle-Neal Interstate
                         Banking and Branching Act (Riegle-Neal Act), a bank
                         holding company may acquire banks in states other than
                         its home state, subject to any state requirement that
                         the bank has been organized and operating for a minimum
                         period of time, not to exceed five years, and the
                         requirement that the bank holding company not control,
                         prior to or following the proposed acquisition, more
                         than 10% of the total amount of deposits of insured
                         depository institutions nationwide or, unless the
                         acquisition is the bank holding company's initial entry
                         into the state, more than 30% of such deposits in the
                         state, or such lesser or greater amount set by the
                         state.

                         The Riegle-Neal Act also authorizes banks to merge
                         across state lines, thereby creating interstate
                         branches. States may opt out of the Interstate Banking
                         Act and thereby prohibit interstate mergers in the
                         state. Wells Fargo will be unable to consolidate its
                         banking operations in one state with those of another
                         state if either state in question has opted out of the
                         Riegle-Neal Act. The state of Montana has opted out
                         until at least the year 2001.

                         Regulatory Approval. In determining whether to approve
                         a proposed bank acquisition, federal banking regulators
                         will consider, among other factors, the effect of the
                         acquisition on competition, the public benefits
                         expected to be received from the acquisition, the
                         projected capital ratios and levels on a post-
                         acquisition basis, and the acquiring institution's
                         record of addressing the credit needs of the
                         communities it serves, including the needs of low and
                         moderate income neighborhoods, consistent with the safe
                         and sound operation of the bank, under the Community
                         Reinvestment Act of 1977.

                                       50

    Dividend   Wells Fargo & Company is a legal entity separate and distinct
Restrictions   from its subsidiary banks and other subsidiaries. Its principal
               source of funds to pay dividends on its common and preferred
               stock and debt service on its debt is dividends from its
               subsidiaries. Various federal and state statutory provisions and
               regulations limit the amount of dividends that Wells Fargo's bank
               subsidiaries may pay without regulatory approval. Dividends
               payable by a national bank without the express approval of the
               OCC are limited to the bank's retained net profits for the
               preceding two calendar years plus retained net profits up to the
               date of any dividend declaration in the current calendar year.
               The OCC defines retained net profits as net income, less
               dividends declared during the period, both of which are based on
               regulatory accounting principles. Wells Fargo's state-chartered
               subsidiary banks also are subject to state regulations that limit
               dividends.

               Before Wells Fargo Bank, National Association can declare
               dividends in 1999 without the prior approval of the OCC, it must
               have net income of $1.5 billion plus an amount equal to or
               greater than the dividends declared in 1999. Because it is not
               expected to meet this requirement, Wells Fargo Bank, National
               Association must obtain the prior approval of the OCC before it
               declares any dividends in 1999.

               Federal bank regulatory agencies have the authority to prohibit
               Wells Fargo's subsidiary banks from engaging in unsafe or unsound
               practices in conducting their businesses. The payment of
               dividends, depending on the financial condition of the bank in
               question, could be deemed an unsafe or unsound practice. The
               ability of Wells Fargo's subsidiary banks to pay dividends in the
               future is currently influenced, and could be further influenced,
               by bank regulatory policies and capital guidelines.

     Holding   Transfer of Funds from Banking Subsidiaries. Wells Fargo's
     Company   banking subsidiaries are subject to restrictions under federal
   Structure   law that limit the transfer of funds or other items of value from
               these subsidiaries to Wells Fargo and its nonbanking
               subsidiaries, including affiliates, whether in the form of loans
               and other extensions of credit, investments and asset purchases,
               or as other transactions involving the transfer of value from a
               subsidiary to an affiliate or for the benefit of an affiliate.
               Unless an exemption applies, these transactions by a banking
               subsidiary with a single affiliate are limited to 10% of the
               subsidiary bank's capital and surplus and, with respect to all
               covered transactions with affiliates in the aggregate, to 20% of
               the subsidiary bank's capital and surplus. Also, loans and
               extensions of credit to affiliates generally are required to be
               secured in specified amounts.

               Source of Strength Doctrine. The Federal Reserve Board has a
               policy

                                       51

               that a bank holding company is expected to act as a source of
               financial and managerial strength to each of its subsidiary banks
               and, under appropriate circumstances, to commit resources to
               support each such subsidiary bank. This support may be required
               at times when the bank holding company may not have the resources
               to provide it. Capital loans from Wells Fargo to any of its
               subsidiary banks are subordinate in right of payment to deposits
               and certain other indebtedness of the subsidiary bank. In
               addition, in the event of Wells Fargo's bankruptcy, any
               commitment by Wells Fargo to a federal bank regulatory agency to
               maintain the capital of a subsidiary bank will be assumed by the
               bankruptcy trustee and entitled to a priority of payment.

               Depositor Preference. The Federal Deposit Insurance Act (FDI Act)
               provides that, in the event of the "liquidation or other
               resolution" of an insured depository institution, the claims of
               depositors of the institution, including the claims of the FDIC
               as subrogee of insured depositors, and certain claims for
               administrative expenses of the FDIC as a receiver will have
               priority over other general unsecured claims against the
               institution. If an insured depository institution fails, insured
               and uninsured depositors, along with the FDIC, will have priority
               in payment ahead of unsecured, nondeposit creditors, including
               Wells Fargo.

               Liability of Commonly Controlled Institutions. Under the FDI Act,
               an insured depository institution is generally liable for any
               loss incurred, or reasonably expected to be incurred, by the FDIC
               in connection with (a) the default of a commonly controlled
               insured depository institution or (b) any assistance provided by
               the FDIC to a commonly controlled insured depository institution
               in danger of default. "Default" means generally the appointment
               of a conservator or receiver. "In danger of default" means
               generally the existence of certain conditions indicating that a
               default is likely to occur in the absence of regulatory
               assistance.


       Capital  Wells Fargo and each of its subsidiary banks are subject to
  Requirements  capital adequacy requirements and guidelines administered by the
                Federal Reserve Board, the OCC and/or the FDIC.

                The Federal Deposit Insurance Corporation Act of 1991 (FDICIA)
                required that the Federal Reserve Board, the OCC and the FDIC
                adopt regulations defining five capital tiers for banks: well
                capitalized, adequately capitalized, undercapitalized,
                significantly undercapitalized and critically undercapitalized.
                Failure to meet minimum capital requirements can initiate
                certain mandatory and possibly additional discretionary actions
                by regulators that, if undertaken, could have a material adverse
                effect on Wells Fargo's business.

                Quantitative measures, established by the regulators to ensure
                capital

                                       52
<PAGE>

               adequacy, require that Wells Fargo and each of its bank
               subsidiaries maintain minimum ratios of total capital to risk-
               weighted assets of at least eight percent (8%) and of Tier 1
               capital to risk-weighted assets of at least four percent (4%).

               There are two categories of capital under the guidelines. Tier 1
               capital includes common stockholders' equity, qualifying
               preferred stock and, for bank holding companies, trust preferred
               securities, less goodwill and certain other deductions, including
               the unrealized net gains and losses, after applicable taxes, on
               available-for-sale securities carried at fair value. Tier 2
               capital includes preferred stock not qualifying as Tier 1
               capital, mandatory convertible debt, subordinated debt, certain
               unsecured senior debt issued by Wells Fargo, the allowance for
               loans losses and net unrealized gains on marketable securities,
               subject to limitations established by the guidelines. At least
               half of total capital must be in the form of Tier1 capital.

               Under the guidelines, capital is compared to the relative risk
               related to the balance sheet. To derive the risk included in the
               balance sheet, one of four risk weights (0%, 20%, 50% and 100%)
               is applied to different balance sheet and off-balance sheet
               assets, primarily based on the relative credit risk of the
               counterparty. For example, claims guaranteed by the U.S.
               government or one of its agencies are risk-weighted at 0%. Off-
               balance sheet items, such as loan commitments and derivative
               financial instruments, are also assigned one of the above risk
               weights after calculating balance sheet equivalent amounts. For
               example, certain loan commitments are converted at 50% and then
               risk-weighted at 100%. Derivative financial instruments are
               converted to balance sheet equivalents based on notional values,
               replacement costs and remaining contractual terms. The capital
               amounts and classification are also subject to qualitative
               judgments by the regulators about components, risk weightings and
               other factors. In addition, the federal banking agencies have
               specified minimum "leverage ratio" (the ratio of Tier 1 capital
               to quarterly average total assets) guidelines for bank holding
               companies and state member banks. The minimum leverage ratio
               guideline is three percent (3%) for banking organizations that
               meet certain specified criteria, including that they have the
               highest regulatory rating. All other banking organizations and
               state member banks are required to maintain a leverage ratio of
               three percent (3%) plus an additional cushion of at least two
               percent (2%).

               The Federal Reserve Board's capital guidelines provide that
               banking organizations experiencing internal growth or making
               acquisitions are expected to maintain strong capital positions
               substantially above the minimum supervisory levels, without
               significant reliance on intangible assets. Also, the guidelines
               indicate that the Federal Reserve Board will

                                       53
<PAGE>

               consider a "tangible Tier 1 leverage ratio" in evaluating
               proposals for expansion or new activities. The tangible Tier 1
               leverage ratio is the ratio of a banking organization's Tier 1
               capital (excluding intangibles) to total assets (excluding
               intangibles).

               The Federal Reserve Board, the FDIC and the OCC have adopted
               rules to incorporate market and interest rate risk components
               into their risk-based capital standards. Amendments to the risk-
               based capital requirements, incorporating market risk, became
               effective January 1, 1998. Under the new market risk
               requirements, capital will be allocated to support the amount of
               market risk related to a financial institution's ongoing trading
               activities.

               At June 30, 1999, Wells Fargo's ratio of total capital (the sum
               of Tier 1 and Tier 2 capital) to risk-weighted assets was 11.10%
               and its ratio of Tier 1 capital to risk-weighted assets was
               8.48%. Wells Fargo's leverage ratio at June 30, 1999 was 7.05%.
               Wells Fargo's management believes that each of Wells Fargo's
               subsidiary banks met all capital requirements to which they are
               subject.

               As an additional means to identify problems in the financial
               management of depository institutions, the FDI Act requires
               federal bank regulatory agencies to establish certain non-capital
               safety and soundness standards for institutions for which they
               are the primary federal regulator. The standards relate generally
               to operations and management, asset quality, interest rate
               exposure and executive compensation. The agencies are authorized
               to take action against institutions that fail to meet such
               standards.

               Under FDICIA's prompt corrective action provisions applicable to
               banks, the most recent regulatory notification from the OCC
               concerning each of Wells Fargo's subsidiary banks categorized
               them as well capitalized. To be categorized as well capitalized,
               the institution must maintain a risk-based total capital ratio of
               at least ten percent (10%), a risk-based Tier 1 capital ratio of
               at least six percent (6%) and a leverage ratio of at least five
               percent (5%), and not be subject to a capital directive order.
               There are no conditions or events since that notification that
               management believes have changed the risk-based capital category
               of our subsidiary banks.

               The FDI Act requires federal bank regulatory agencies to take
               "prompt corrective action" with respect to FDIC-insured
               depository institutions that do not meet minimum capital
               requirements. A depository institution's treatment for purposes
               of the prompt corrective action provisions will depend upon how
               its capital levels compare to various capital measures and
               certain other factors, as established by regulation.

                                       54

       FDIC    Through the Bank Insurance Fund (BIF), the FDIC insures the
  Insurance    deposits of Wells Fargo's depository institution subsidiaries up
               to prescribed limits for each depositor. The amount of FDIC
               assessments paid by each BIF member institution is based on its
               relative risk of default as measured by regulatory capital ratios
               and other factors. Specifically, the assessment rate is based on
               the institution's capitalization risk category and supervisory
               subgroup category. An institution's capitalization risk category
               is based on the FDIC's determination of whether the institution
               is well capitalized, adequately capitalized or less than
               adequately capitalized. An institution's supervisory subgroup
               category is based on the FDIC's assessment of the financial
               condition of the institution and the probability that FDIC
               intervention or other corrective action will be required.

               The BIF assessment rate currently ranges from zero to 27 cents
               per $100 of domestic deposits. The FDIC may increase or decrease
               the assessment rate schedule on a semi-annual basis. An increase
               in the BIF assessment rate could have a material adverse effect
               on Wells Fargo's earnings, depending on the amount of the
               increase. The FDIC is authorized to terminate a depository
               institution's deposit insurance upon a finding by the FDIC that
               the institution's financial condition is unsafe or unsound or
               that the institution has engaged in unsafe or unsound practices
               or has violated any applicable rule, regulation, order or
               condition enacted or imposed by the institution's regulatory
               agency. The termination of deposit insurance for one or more of
               Wells Fargo's subsidiary depository institutions could have a
               material adverse effect on Wells Fargo's earnings, depending on
               the collective size of the particular institutions involved.

               All FDIC-insured depository institutions must pay an annual
               assessment to provide funds for the payment of interest on bonds
               issued by the Financing Corporation, a federal corporation
               chartered under the authority of the Federal Housing Finance
               Board. The bonds, commonly referred to as FICO bonds, were issued
               to capitalize the Federal Savings and Loan Insurance Corporation.
               FDIC-insured depository institutions will continue to pay
               approximately 1.2 cents per $100 of BIF-assessable deposits until
               the earlier of December 31, 1999 or the date the last savings and
               loan association ceases to exist.


Fiscal And     Wells Fargo's business and earnings are affected significantly by
  Monetary     the fiscal and monetary policies of the federal government and
  Policies     its agencies. Wells Fargo is particularly affected by the
               policies of the Federal Reserve Board, which regulates the supply
               of money and credit in the

                                       55
<PAGE>

               United States. Among the instruments of monetary policy available
               to the Federal Reserve are (a) conducting open market operations
               in United States government securities, (b) changing the discount
               rates of borrowings of depository institutions, (c) imposing or
               changing reserve requirements against depository institutions'
               deposits, and (d) imposing or changing reserve requirements
               against certain borrowing by banks and their affiliates. These
               methods are used in varying degrees and combinations to directly
               affect the availability of bank loans and deposits, as well as
               the interest rates charged on loans and paid on deposits. For
               that reason alone, the policies of the Federal Reserve Board have
               a material effect on the earnings of Wells Fargo.

Competition    The financial services industry is highly competitive. Wells
               Fargo's subsidiaries compete with financial services providers,
               such as banks, savings and loan associations, credit unions,
               finance companies, mortgage banking companies, insurance
               companies, and money market and mutual fund companies. They also
               face increased competition from non-banking institutions such as
               brokerage houses and insurance companies, as well as from
               financial services subsidiaries of commercial and manufacturing
               companies. Many of these competitors enjoy the benefits of
               advanced technology, fewer regulatory constraints and lower cost
               structures.

               The financial services industry is likely to become even more
               competitive as further technological advances enable more
               companies to provide financial services. These technological
               advances may diminish the importance of depository institutions
               and other financial intermediaries in the transfer of funds
               between parties.

Information About TBI
- --------------------------------------------------------------------------------

       General      TBI is a bank holding company, registered under the Bank
                    Holding Company Act, whose sole activity is the ownership
                    and operation of its subsidiary banks. TBI was incorporated
                    in 1981 under the name Rio Grande City Bancshares, Inc.
                    TBI's corporate name was changed to Texas Bancshares, Inc.
                    in 1992.

                    First National Bank of South Texas (FNB) is a national bank
                    which was founded in 1976. First National Bank currently
                    operates a total of 7 offices in South Texas.

                    The Bank of South Texas is a Texas state banking association
                    which was formed in 1902. The Bank of South Texas currently
                    operates a total of 3 offices in South Texas.

                    FNB and The Bank of South Texas conduct a general commercial
                    and consumer banking business, including the acceptance of
                    deposits from consumers and the origination of commercial
                    and consumer real estate, installment and other loans.
                    Deposit services include certificates of deposit, individual
                    retirement accounts and other time deposits, checking and
                    other demand deposit accounts, interest-bearing accounts,
                    savings accounts and money market accounts from customers
                    principally located in Nueces, Wilson, Bexar, Atascosa and
                    Jim Wells counties in South Texas. Loans consist of loans to
                    individuals, commercial loans, commercial real estate loans,
                    residential mortgages and construction loans.


   Competition      TBI's subsidiary banks experience competition in attracting
                    both loans and deposits from other banks and non-bank
                    financial institutions located in their market area. Non-
                    bank competitors with respect to deposits and deposit-type
                    accounts include savings and loan associations, credit
                    unions, securities firms, money market funds, life insurance
                    companies and the mutual funds industry. With respect to
                    loans, TBI's subsidiary banks encounter competition from
                    other banks, savings and loan associations, finance
                    companies, insurance companies, small loan and credit card
                    companies, credit unions, pension trusts and securities
                    firms.

                    In Texas, the nature of the competition in the banking
                    business has changed considerably in recent years, with more
                    large, out-of-state banking organizations having entered the
                    banks' markets. While such fundamental changes create
                    opportunities for well-managed institutions regardless of
                    size, TBI's subsidiary banks' competition increasingly

                                       60
<PAGE>

                    consists of regional, money center institutions which have
                    capital resources and legal loan limits substantially in
                    excess of those maintained by the banks. The banks have a
                    number of competitive advantages over such institutions in
                    the area of customer service and ability to respond quickly
                    to customer needs; however, such institutions can perform
                    certain other functions for their customers, including
                    trust, securities brokerage and international banking
                    services, which the banks presently do not offer directly.
                    Although TBI's subsidiary banks could offer these services
                    through a correspondent bank or through a joint venture
                    arrangement with other specialized companies, the inability
                    to provide such services directly can be a competitive
                    disadvantage.

      Regulation    Banking is a complex and highly regulated industry. The
             And    primary goals of the bank regulatory scheme are to maintain
     Supervision    a safe and sound banking system and to facilitate the
                    conduct of monetary policy.

                    Regulation of TBI. As a bank holding company under the Bank
                    Holding Company Act, TBI is registered with and subject to
                    regulation by the Board of Governors of the Federal Reserve
                    System. TBI is required to file annual and other reports
                    with, and furnish information to, the Federal Reserve Board,
                    which may make inspections of TBI.

                    The Bank Holding Company Act provides that a bank holding
                    company must obtain the prior approval of the Federal
                    Reserve Board for the acquisition of more than 5% of the
                    voting stock or substantially all the assets of any bank or
                    bank holding company. In addition, the Bank Holding Company
                    Act restricts the extension of credit to any bank holding
                    company by its subsidiary bank. The Bank Holding Company Act
                    also provides that, with certain exceptions, a bank holding
                    company may not (a) engage in any activities other than
                    those of banking or managing or controlling banks and other
                    authorized subsidiaries or (b) own or control more than 5%
                    of the voting shares of any company that is not a bank. The
                    Federal Reserve Board has deemed certain limited activities
                    to be closely related to banking and therefore permissible
                    for a bank holding company to engage.

                    In 1994, Congress enacted the Riegle-Neal Interstate Banking
                    and Branching Efficiency Act of 1994 (Interstate Banking
                    Act), which rewrote federal law governing the interstate
                    expansion of banks in the United States. Effective as of
                    September 29, 1995, adequately capitalized, well managed
                    bank holding companies with Federal Reserved Board approval
                    may acquire banks located in any state in the United States,
                    provided that the target bank meets the minimum age (up to a
                    maximum of five years, which is the maximum Texas has
                    adopted) established by the host state. Under the Interstate
                    Banking Act, an anti-concentration limit will bar interstate
                    acquisitions that would give a bank

                                       61
<PAGE>

                    holding company control of more than 10% of all deposits
                    nationwide or 30% of any one state's deposits, or such
                    higher or lower percentage established by the host state.
                    The anti-concentration limit in Texas has been set at 20% of
                    all federally insured deposits in Texas. As of December 31,
                    1998, many of Texas's largest bank holding companies had
                    either merged with or been acquired by out-of-state banking
                    concerns. In addition to providing for interstate
                    acquisitions of banks by bank holding companies, the
                    Interstate Banking Act provides for interstate branching by
                    permitting mergers between banks domiciled in different
                    states beginning June 1, 1997. The Interstate Banking Act
                    provides that states may opt out of interstate branching by
                    enacting non-discriminatory legislation prohibiting
                    interstate bank mergers before June 1, 1997. In 1995, Texas
                    passed legislation opting out of the interstate branching
                    provisions of the Interstate Banking Act until September
                    1999. In May 1998, the Texas Department of Banking
                    determined that the Texas opt-out statute was not effective
                    and the Texas Department of Banking began accepting
                    applications for interstate branching transactions.
                    Legislation implementing interstate branching was recently
                    adopted in the Texas legislature. No accurate prediction can
                    be made at this time as to how this legislation will affect
                    TBI and/or its subsidiary banks.

                    TBI and its bank subsidiaries are currently required to meet
                    certain minimum regulatory capital guidelines utilizing
                    total capital-to-risk-weighted assets and Tier 1 capital
                    elements. At June 30, 1999, TBI's ratio of total capital-to-
                    risk-weighted assets was 12.89%. The guidelines make
                    regulatory capital requirements more sensitive to
                    differences in risk profiles among banking organizations,
                    take off-balance sheet exposure into account in assessing
                    capital adequacy, and encourage the holding of liquid, low-
                    risk assets. At least one-half of the minimum total capital
                    must be comprised of Tier 1 capital elements. Tier 1 capital
                    of TBI is comprised of common shareholders' equity. The core
                    deposit intangibles and goodwill of approximately $4,152,000
                    booked in connection with all the financial institution
                    acquisitions of TBI as of June 30, 1999 are deducted from
                    the sum of core capital elements when determining the
                    capital ratios of TBI.

                    In addition, the Federal Reserve Board has established
                    minimum leverage ratio guidelines for bank holding
                    companies. These guidelines provide for a minimum leverage
                    ratio of Tier 1 capital to adjusted average quarterly assets
                    ("leverage ratio") equal to three percent for bank holding
                    companies that meet certain specified criteria, including
                    having the highest regulatory rating. All other bank holding
                    companies will generally be required to maintain a leverage
                    ratio of at least four to five percent. TBI's leverage ratio
                    at June 30, 1999 was 7.67%. The guidelines also provide that
                    bank holding companies experiencing


                                       62
<PAGE>

                    internal growth or making acquisitions will be expected to
                    maintain strong capital positions substantially above the
                    minimum supervisory levels without significant reliance on
                    intangible assets. Furthermore, the guidelines indicate that
                    the Federal Reserve Board will continue to consider a
                    "tangible Tier 1 leverage ratio" (deducting all intangibles)
                    in evaluating proposals for expansion or new activity. The
                    Federal Reserve Board has not advised TBI of any specific
                    minimum leverage ratio or tangible tier 1 leverage ratio
                    applicable to it.

                    For a general discussion of the risk-based capital
                    guidelines and the criteria applied to calculate the ratios,
                    see "Regulation And Supervision Of Wells Fargo--Capital
                    Requirements."

                    The Federal Reserve Board has cease-and-desist powers over
                    parent holding companies and nonbanking subsidiaries if
                    their actions would constitute a serious threat to the
                    safety, soundness or stability of a subsidiary bank. Federal
                    regulatory agencies also have authority to regulate debt
                    obligations (other than commercial paper) issued by bank
                    holding companies. This authority includes the power to
                    impose interest ceilings and reserve requirements on such
                    debt obligations. A bank holding company and its
                    subsidiaries are also prohibited from engaging in certain
                    tie-in arrangements in connection with any extension of
                    credit, lease or sale of property or furnishing of services.

                    Regulation of The Bank of South Texas. As a Texas state
                    banking association, The Bank of South Texas is principally
                    supervised, examined and regulated by the Texas Department
                    of Banking and the Federal Deposit Insurance Corporation
                    (FDIC). The Bank of South Texas is subject to the power of
                    the FDIC to enforce compliance with applicable banking
                    statutes and regulations. Such requirements and restrictions
                    include requirements to maintain adequate capital and
                    reserves against deposits, restrictions on the nature and
                    amount of loans that may be made and the interest that may
                    be charged thereon and restrictions relating to investments
                    and other activities of The Bank of South Texas. Because the
                    Federal Reserve Board regulates TBI, it also has supervisory
                    authority which affects The Bank of South Texas.

                    Regulation of FNB. As a national banking association, FNB is
                    principally supervised, examined and regulated by the Office
                    of the Comptroller of the Currency (OCC). The OCC regularly
                    examines such areas as capital adequacy, reserves, loan
                    portfolio, investments and management practices. FNB must
                    also furnish quarterly and annual reports to the OCC, and
                    the OCC may exercise cease and desist and other enforcement
                    powers over FNB if its actions represent unsafe or unsound
                    practices or violations of law. Since the deposits of FNB
                    are insured by the Bank Insurance Fund (BIF) of the FDIC,
                    FNB is also

                                       63
<PAGE>

                    subject to certain regulation by the FDIC. Because the
                    Federal Reserve Board regulates TBI, it also has supervisory
                    authority which affects FNB.

                    FDIC Insurance. The capital classification of a bank affects
                    the frequency of examinations of the bank, impacts the
                    ability of the bank to engage in certain activities and
                    affects the deposit insurance premiums paid by such bank.
                    The Bank of South Texas' and FNB's deposits are insured by
                    the Bank Insurance Fund of the FDIC. Under applicable law,
                    the FDIC is authorized to assess insurance premiums on a
                    bank's deposits at a variable rate depending on the
                    probability that the deposit insurance fund will incur a
                    loss with respect to the bank. (Under prior law, the deposit
                    insurance assessment was a flat rate, regardless of the
                    likelihood of loss.) In this regard, the FDIC determines the
                    deposit insurance assessment rates on the basis of the
                    bank's capital classification and supervisory evaluations.
                    Each of these categories have three subcategories, resulting
                    in nine assessment risk classifications. The three
                    subcategories with respect to capital are "well
                    capitalized," "adequately capitalized," and "less than
                    adequately capitalized." The three subcategories with
                    respect to supervisory concerns are "healthy," "supervisory
                    concern," and "substantial supervisory concern." A bank is
                    deemed "healthy" if it is financially sound with only a few
                    minor weaknesses. A bank is deemed subject to "supervisory
                    concern" if it has weaknesses that, if not corrected, could
                    result in significant deterioration of the bank and
                    increased risk to the Bank Insurance Fund. A bank is deemed
                    subject to "substantial supervisory concern" if it poses a
                    substantial probability of loss to the Bank Insurance Fund.
                    As of June 30, 1999, the Banks were both rated "well
                    capitalized" and "healthy."

                    On November 14, 1995, the FDIC approved assessment rates
                    applicable to BIF-insured institutions to a range of zero to
                    27 basis points from the previous range of 4 to 31 points.
                    Deposit insurance premiums for Subgroup A institutions were
                    reduced to zero beginning with the January 1, 1996
                    assessment period. Banks within the Subgroup A category will
                    be required to pay $1,000 per semiannual period as mandated
                    by statute. TBI's subsidiary banks were within the Subgroup
                    A category as of June 30, 1999. For a general discussion
                    concerning the criteria applied by the FDIC to determine an
                    institution's insurance premium assessment rate, see
                    "Regulation And Supervision Of Wells Fargo--FDIC Insurance.


       Employees    TBI is a bank holding company and primarily conducts its
                    operations through its subsidiary banks. TBI does not have
                    any full-time employees, and all operations personnel are
                    employed by the banks. FNB had approximately 148 full-time
                    employees and 14 part-time

                               employees as of June 30, 1999. The Bank of South
                               Texas had approximately 26 full-time employees
                               and 5 part-time employees as of June 30, 1999.
                               None of the employees are represented by any
                               collective bargaining agreement, and management
                               believes its employee relations are good. TBI and
                               its subsidiaries are equal opportunity employers
                               and provide equal employment opportunities to
                               individuals without regard to race, sex, national

     Holders Of TBI      At June 30, 1999, there were 1,966,536 shares of TBI
             Common      common stock outstanding, owned of record by 266
              Stock      shareholders, and options to acquire a total of 59,500
                         shares were held by 23 employees. There is no
                         established public market for TBI common stock. TBI
                         acts as its own transfer agent and registrar with
                         respect to its common stock.


              Legal      The banks are periodically involved in legal
        Proceedings      proceedings arising in the normal course of business,
                         such as claims to enforce liens, claims involving the
                         making and servicing of real property loans and other
                         issues incident to the banks' business. Management of
                         TBI does not believe there is any proceeding,
                         threatened or pending against TBI or either of the
                         banks which, if determined adversely, would have a
                         materially adverse effect on the financial position or
                         results of operation of TBI.


       Ownership Of      The following table sets forth, as of August 1, 1999,
         TBI Common      (a) the names and addresses of each person known by TBI
       Stock By TBI      to be the beneficial owner of more than 5% of the
         Management      outstanding shares of TBI common stock, showing the
                         amount and nature of such beneficial ownership, (b) the
                         names of each director and executive officer of TBI,
                         and the number of shares of TBI common stock
                         beneficially owned by each director and executive
                         officer and (c) the number of shares of TBI common
                         stock owned beneficially by all directors and executive
                         officers as a group. None of the shareholders listed

(Note 1)  The change in interest due to both rate and volume has been allocated
          to volume and rate changes in proportion to the relationship of the
          absolute dollar amounts of the change in each.

     Provision for Possible Loan Losses.  The provision for possible loan losses
increased by $618,000 for the six months ended June 30, 1999, compared with the
six months ended June 30, 1998, as management determined that the current
exposure for possible loan losses warranted an increase in the allowance for
possible loan losses.

     Noninterest Income.  Non-interest income increased by $995,000 for the six
months ended June 30, 1999 compared with the six months ended June 30, 1998.
This included an increase of $166,000 in service charge income, an increase of
$210,000 for sales of securities and a gain of $635,000 on sale of a single
piece of land to an unrelated third party.

     Noninterest Expense. Non-interest expense increased by $630,000 for the six
months ended June 30, 1999 compared with the six months ended June 30, 1998.
This increase resulted primarily from an aggregate increase of $435,000 in
salaries, occupancy, data processing and communication expense, as a result of
the costs associated with expanding branch operations for growth opportunities
and $121,000 for consulting fees related to the Company's new product, Overdraft
Privilege.

Years Ended December 31, 1998, 1997 and 1996

     Generally. Net income was $3,327,000, $2,860,000, and $611,000 for the
years ended December 31, 1998, 1997 and 1996, respectively.

     The increase in net income for 1998 compared to 1997 was caused primarily
by the increase in interest and fees on loans of $3,614,000 and service charge
income of $1,765,000, primarily, related to the Company's new product, Overdraft
Privilege.

     The increase in net income for 1997 compared to 1996 was caused primarily
by the increase in interest and fees on loans of $1,158,000, and the reduction
of litigation expense of $1,000,000.

     Following is a discussion of changes in the major components of net income
for the years ending December 31, 1998, 1997 and 1996.

     Net Interest Income. Net interest income is the principal source of TBI's
net income and represents the difference between interest income and interest
expense. Net interest income increased approximately $1,509,000 in 1998 compared
to 1997 as a result of an increase in average interest-earning assets of
$36,589,000, partially offset by an increase in average interest-bearing
liabilities of $25,408,000. Net interest income increased approximately
$1,513,000 in 1997 compared to 1996, as a result of an increase in average
interest-earning assets of $19,399,000, partially offset by an increase in
average interest-bearing liabilities of $14,752,000.

    Net interest income is affected both by the interest rate ended and paid and
by changes in volume, principally in loans, investments securities, deposits and
borrowed funds. The following table depicts the dollar effect and rate changes
for interest-earning assets and interest-bearing liabilities and the resulting
change in interest income and interest expense (Note 1):

(Note 1) The change in interest due to both rate and volume has been allocated
         to volume and rate changes in proportion to the relationship of the
         absolute dollar amounts of the change in each.

       year ended December 31, 1998 compared with the year ended December 31,
       1997. This included an increase of $1,765,000 in service charges from a
       new product, Overdraft Privilege.

         Noninterest income increased by $297,000 for the year ended December
       31, 1997 compared with the year ended December 31, 1996. This included an
       increase of $186,000 in service charge income, as the management focused
       on fee income products.

         Noninterest Expense. Noninterest expense increased by $1,765,000 for
       the year ended December 31, 1998, compared with the year ended December
       31, 1997. This included an increase of $995,000 in salaries and employee
       benefits, a decrease in occupancy expense of $2,000 , and an increase in
       other expense of $772,000, resulting from consulting fees of $246,000
       related to the new Overdraft Privilege product, advertising fees of
       $130,000 related to the new Overdraft Privilege product, an increase in
       data processing fees of $151,000, and an increase in operating expenses

     The allowance for loan losses is allocated to specific categories of loans,
and based on TBI's review of remaining collateral and/or financial condition of
identified loans with characteristically more than a normal degree of risk,
historical loan loss percentages, and economic conditions, management believes
the allowance for loan losses at June 30, 1999, is adequate to cover losses
inherent in the portfolio.

          The reserve for loan losses is established through a provision for
     loan losses charged to operations. Loans are charged against the reserve
     for loan losses when management believes that the collectibility of the
     principal is unlikely. The reserve is an amount that management believes
     will be adequate to absorb possible losses on existing loans that may
     become uncollectible, based on evaluations of the collectibility of loans
     and prior loan loss experience. The evaluations take into consideration
     such factors as changes in the nature and volume of the loan portfolio,
     overall portfolio quality, review of specific problem loans, and current
     economic conditions that may affect the borrower's ability to pay. Accrual
     of interest is discontinued on a loan when management believes, after
     considering economic and business conditions and collection efforts, that
     the borrower's financial condition is such that collection of interest is
     doubtful. When interest accrual is discontinued, all unpaid accrued
     interest is reversed. Interest income is subsequently recognized only to
     the extent cash payments are received.

     Non-performing Assets

          Non-performing assets are defined as loans delinquent 90 or more days,
     nonaccrual loans, restructured loans, and foreclosed loans. Such assets do
     not necessarily represent future losses to TBI since underlying collateral
     may be sold and the financial condition of the borrowers may improve. The
     following table sets forth the detail of nonperforming loans.

     Total non-performing loans as a percentage of total loans was 0.26% and
0.16% at June 30, 1999 and 1998, respectively, and 0.36%, and 0.49% at December
31, 1998 and 1997, respectively.

     Management does not believe there will be any losses associated with the
loans as they have estimated that the underlying collateral could be sold for in
excess of the loan balances.

     TBI's policy is to discontinue accruing interest on loans when principal or
interest is due and remains unpaid for 90 days or more, unless the loan is well
secured and in the process of collection. The additional interest income that
TBI would have recognized for the six months ended June 30, 1999 and for the
year ended December 31, 1998, if contractural interest on these loans had been
recognized, is insignificant.

     At June 30, 1999, there were no commitments to lend additional funds to
borrowers whose loans were considered non-performing.

     Management is not aware of any loans other than those included as non-
performing loans where known information about possible credit problems causes
serious doubts as to the borrower's ability to comply with repayment terms which
may result in such loans becoming non-performing.

     The loan portfolio does not include any loans to foreign countries or
highly leveraged transaction loans. Senior management closely monitors
concentrations to individual customers and actively participates within their
lending areas. TBI has written policies that require security for loans
including liens on residential mortgage loans and certain of the other loans
secured by real estate. In addition, policies and procedures are in place to
assess the creditworthiness of borrowers for all loans and commitments. A
borrower's ability to honor loan contracts can be largely dependent upon
economic conditions within TBI's market areas.

Investments

     The Company classifies debt securities, including mortgage-backed
securities, as either held-to-maturity or available-for-sale. Debt securities
classified as held-to-maturity are those which the Company has the positive
intent and ability to hold until maturity. These securities are carried at
amortized cost with premiums and discounts being amortized using the effective
interest method over the estimated remaining life of the security. Securities
classified as available-for-sale are carried at fair value with unrealized gains
or losses (net of deferred income taxes) reflected in stockholders' equity.
Gains and losses recognized on the sale of securities are based on the specific
identification method. Mortgage-backed securities represent participating
interests in pools of long-term first mortgage loans originated and serviced by
the issuers of the securities. Mortgage-backed securities are either issued or
guaranteed by the U. S. Government or its agencies. Mortgage-backed securities
that are held-to-maturity are carried at unpaid principal balances, adjusted for
unamortized premiums and unearned discounts. Premiums and discounts are
amortized using the straight-line method over the remaining period to
contractual maturity. The mortgage-backed securities that are available-for-sale
are carried at fair value. Market interest rate fluctuations can affect the
prepayment speed of principal and the market value and yield on the security. As
of December 31, 1998 and June 30, 1999, TBI's securities are classified as
either available for sale or held to maturity.

Deposits

     The deposit base provides the major funding source for the interest earning
assets of TBI.  In general, TBI's deposits have increased during the period from
December 31, 1997 to December 31, 1998, as well as from June 30, 1998 to June
30, 1999.  Management believes that demand, savings and certificates of deposit
less than $100,000 represent a core base of deposits while certificates of
deposit in excess of $100,000 and public funds are more interest rate sensitive
and, thus, not viewed as part of the core deposit base.  Because of these
factors, management views the growth of demand, savings and time certificates of
deposit less than $100,000 as more stable growth.

     The following table reflects the average balance (Note 1) and average
interest rate paid (Note 2) on deposits for the period presented.

Liquidity

     TBI's principal source of funds consists of dividends from its subsidiary
banks, which derive their funds from deposits, interest, and principal payments
on loans and investment securities, sales of investment securities and
borrowings. For the six month period ended June 30, 1999, TBI realized proceeds
from sales and maturities of investments of $27,765,000, a net increase in
deposits of $802,000 and net cash provided by operating activities of
$2,601,000. Funds were used to acquire investment securities of $42,856,000. For
the six month period ended June 30, 1998, TBI realized proceeds from sales and
maturities of investments of $30,171,000, a net increase in deposits of
$14,844,000 and net cash provided by operating activities of $2,600,000. Funds
were used to acquire investment securities of $31,495,000 and fund a net
increase in loans to customers of $21,732,000. For the year ended December 31,
1998, TBI realized proceeds from sales and maturities of investments of
$64,957,000, a net increase in deposits of $42,736,000 and net cash provided by
operating activities of $5,577,000. Funds were used to acquire investment
securities of $67,177,000 and fund a net increase in loans to customers of
$41,506,000. For the year ended December 31, 1997, TBI realized proceeds from
sales and maturities of investment securities of $38,232,000, net cash provided
by operating activities of $3,680,000 and a net increase in deposits of
$19,273,000. These proceeds were partially offset by a purchase of investment
securities of $26,354,000 and a net increase in loans to customers of
$33,606,000. For the year ended December 31, 1996, TBI realized proceeds from
sales and maturities of investment securities of $52,899,000, net cash provided
by operating activities of $3,157,000, and a net income in deposits of
$9,319,000. These proceeds were partially offset by

                                       84
<PAGE>

a purchase of investment securities of $59,045,000 and a net increase in loans
to customers of $11,065,000.

     Asset liquidity is provided by cash and federal funds sold. Liability
liquidity is provided by access to core funding sources, principally various
customers' interest-bearing accounts in TBI's market areas. TBI does not have
and does not solicit brokered deposits.

     Federal funds purchased and short-term borrowings by TBI are additional
sources of liquidity. These sources of liquidity are short-term in nature and
are used by TBI as necessary to fund asset growth and meet short-term liquidity
needs. As of June 30, 1999 and 1998, and December 31, 1998 and 1997, TBI had no
federal funds purchased and no borrowings on securities sold under repurchase
agreements. TBI had $3,373,000 and $2,935,000 outstanding under lines of credit
at the Federal Home Loan Bank on June 30, 1999 and December 31, 1998,
respectively. There were no outstanding balances with the Federal Home Loan Bank
at June 30, 1998 or December 31, 1997.

Capital

     TBI's total shareholders' equity as of June 30, 1999 was $32,559,000, an
increase of $660,000 or 2.08%, compared with shareholders' equity of $31,893,000
as of December 31, 1998.

     Total shareholders' equity as of December 31, 1998 was $31,893,000, an
increase of $3,280,000 or 11.46%, compared with shareholders' equity of
$28,613,000 as of December 31, 1997.

     TBI is 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 TBI's
financial statements. Under capital adequacy guidelines and the regulatory
framework for prompt corrective action, TBI must meet specific capital
guidelines that involve quantitative measures of TBI's assets, liabilities, and
certain off-balance-sheet items as calculated under regulatory accounting
practices. TBI'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 TBI to maintain minimum amounts and ratios, set forth in the
table below of total and Tier I capital (as defined in the regulations) to risk-
weighted assets (as defined in the regulations), and of Tier I capital (as
defined in the regulations) to average assets (as defined in the regulations).
Management believes that TBI meets, as of June 30, 1999 and December 31, 1998,
all capital adequacy requirements to which it is subject.

     As of June 30, 1999 and December 31, 1998, the most recent notification
from the Office of the Comptroller of the Currency and the FDIC categorized the
TBI's subsidiary banks and the consolidated entity as well capitalized under the
regulatory framework for prompt corrective action. To be categorized as well
capitalized, the banks and the consolidated entity must maintain minimum total
risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the
table. There are no conditions or events since that notification that management
believes have changed the banks' or consolidated entity's category.

</TABLE>

     The FRB has adopted risk-based capital guidelines which assign risk
weightings to assets and off-balance sheet items. The guidelines also define and
set minimum capital requirements (risk-based capital ratios). Under the final
1992 rules, all banks are required to have core capital (Tier 1) of at least
4.0% of risk-weighted assets and total capital of 8.0% of risk-weighted assets.
Tier 1 capital consists principally of shareholders' equity less goodwill and
certain other intangibles, while total capital consists of core capital, certain
debt instruments and a portion of the reserve for credit losses. In order to be
deemed well capitalized pursuant to the regulations, an institution must have a
total risk-weighted capital ratio of 10%, a Tier 1 risk-weighted ratio of 6% and
a Tier 1 leverage ratio of 5%. The Company had risk-weighted Tier 1 capital
ratios of 11.14% and 11.20% and risk-weighted total capital ratios of 11.97% and
11.90% for December 31, 1998 and 1997, respectively, which are well above the
minimum regulatory requirements and exceed the well capitalized ratios (see note
13 to notes to Consolidated Financial Statements). At June 30, 1999 and 1998,
respectively, the Company had risk-weighted Tier 1 capital ratios of 12.05% and
11.08% and risk-weighted total capital ratios of 12.89% and 11.83%.

Impact of Inflation, Changing Prices and Monetary Policies

     The financial statements and related financial data concerning TBI
presented in this proxy statement-prospectus have been prepared in accordance
with generally accepted accounting principles, which require the measurement of
financial position and operating results in terms of historical dollars without
considering changes in the relative purchasing power of money over time due to
inflation. The primary effect of inflation on the operation of TBI is reflected
in increased operating costs. Unlike most industrial companies, virtually all of
the assets and liabilities of a financial institution are monetary in nature. As
a result, changes in interest rates

                                       86
<PAGE>

have a more significant effect on the performance of a financial institution
than do the effects of changes in the general rate of inflation and changes in
price. Interest rates do not necessarily move in the same direction or in the
same magnitude as the prices of goods and services. Interest rates are highly
sensitive to many factors which are beyond the control of TBI, including the
influence of domestic and foreign economic conditions and the monetary and
fiscal policies of the United States government and federal agencies,
particularly the Federal Reserve Board. The Federal Reserve Board implements
national monetary policy such as seeking to curb inflation and combat recession
by its open market operations in the United States government securities,
control of the discount rate applicable to borrowing by banks and establishment
of reserve requirements against bank deposits. The actions of the Federal
Reserve Board in these areas influence the growth of bank loans, investments and
deposits, and effect the interest rates charged on loans and paid on deposits.
The nature, timing and impact of any future changes in federal monetary and
fiscal policies on TBI and its subsidiary banks and their results of operations
are not predictable.

Year 2000 Compliance

     In 1997, TBI initiated a plan to identify, assess, and remediate "Year
2000" issues within each of its significant computer programs and certain
equipment which contain micro-processors. The Year 2000 plan is addressing the
issue of computer programs and embedded computer chips being able to distinguish
between the year 1900 and the year 2000, if a program or chip uses only two
digits rather than four to define the applicable year. TBI has divided the Plan
into five major phases - assessment, planning, conversion, implementation and
testing. In 1997, TBI completed the assessment and planning phases. In 1998, TBI
conducted testing on critical systems followed by any necessary implementation
or conversion processes. Systems which have been determined not to be Year 2000
compliant are being either replaced or reprogrammed, and thereafter tested for
Year 2000 compliance. At mid-1999, TBI had completed all testing and
implementation phases for critical systems. TBI had also completed written
contingency plans and tested the plans accordingly.

     TBI is in the process of identifying and contacting critical suppliers and
customers whose computerized systems interface with TBI's systems, regarding
their plans and progress in addressing their Year 2000 issues.  TBI has received
varying information from such third parties on the state of compliance or
expected compliance. Contingency plans are being developed in the event that any
critical supplier or customer is not compliant.

     The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations.  Such failures could materially and adversely affect TBI's
operations, liquidity and financial condition.  Due to the general uncertainty
inherent in the Year 2000 problem, resulting in part from the uncertainty of the
Year 2000 readiness of third-party suppliers and customers, TBI is unable to
determine at this time whether the consequences of Year 2000 failures will have
a material impact on TBI's operations, liquidity or financial condition.

Recent Accounting Pronouncements

     TBI adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of", effective January 1, 1996.
This statement established accounting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles which must be disposed.  Long-lived assets and certain identifiable
intangibles to be disposed of must be reported at the lower of carrying amount
or fair value less cost to sell, except for assets that are covered by APB
Opinion, No. 30.  The adoption of this statement did not have a material impact
on TBI's consolidated financial position, results of operation, or liquidity.

     In 1997, TBI adopted SFAS No. 123, "Accounting for Stock-Based
Compensation." SFAS No. 123 permits companies to recognize as expense over the
vesting period the fair value of all stock-based awards on the date of grant. In
management's opinion, the existing stock option valuation models do not
necessarily provide a reliable single measure of stock option fair value.
Therefore, as permitted, TBI will continue to apply the existing accounting
rules under APB No. 25 and provide pro forma net income and pro forma earnings
per share disclosures for employee stock option grants made in 1997 and
subsequent years as if the fair-value-based method defined in SFAS No. 123 had
been applied.

     In June 1996, the Financial Accounting Standards Board issued SFAS No. 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities."  SFAS No. 127, "Deferral of the Effective Date of Certain
Provisions of FASB Statement No. 125" was issued in December 1996.  SFAS No. 127
defers portions of SFAS No. 125 to be effective for transfers and servicing of
financial assets and extinguishments of liabilities occurring after December 31,
1997.  These statements are to be applied prospectively.  SFAS No. 125 provides
accounting and extinguishments of liabilities based on consistent application of
a financial-components approach that focuses on control.  It distinguishes
transfers of financial assets that are sales from transfers that are secured
borrowings.  The adoption of this statement did not have a material impact on
TBI's consolidated financial position, results of operations, or liquidity.

     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings per Share."  SFAS No. 128 specifies the computation,
presentation, and disclosure requirements for earnings per share (EPS) for
entities with publicly held common stock or potential common stock.  SFAS No.
128 replaces primary EPS and fully diluted EPS on the face of the income
statement for all entities with complex capital structures and requires a
reconciliation of the basic EPS computation to the diluted EPS.  Basic EPS is
calculated by dividing net income available to common shareholders, by the
weighted average of number of common shares outstanding.  The computation of
diluted EPS assumes the issuance of common shares for all dilutive potential
common shares outstanding during the reporting period.  The dilutive effect of
stock options are considered in earnings per share calculations if dilutive,
using the treasury stock method.  SFAS No. 128 was effective for financial
statements issued for periods ending after December 15, 1997, including interim
periods.  TBI adopted SFAS No. 128 in 1997, accordingly, all prior-period
earnings per share data presented in the accompanying consolidated financial
statements has been restated to conform to the requirements of SFAS No. 128.

     In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income."  SFAS No. 130 establishes standards for
reporting and display of

                                       88
<PAGE>

comprehensive income and its components (revenues, expenses, gains, and losses)
in a full set of general-purpose financial statements. SFAS No. 130 requires
that an enterprise (a) classify items of other comprehensive income by their
nature in a financial statement and (b) display the accumulated balance of other
comprehensive income separately from retained earnings and additional paid-in
capital in the equity section of a statement of financial position. SFAS No. 130
was effective for fiscal years beginning after December 15, 1997. The adoption
of this Statement did not have a material impact on TBI's consolidated financial
position, results of operations, or liquidity.

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
the "Accounting for Derivative Instruments and Hedging Activities."  SFAS No.
133 establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities.  SFAS No. 133 requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value.  If certain conditions are
met, a derivative may be specifically designated as a "fair value hedge," a
"cash flow hedge," or a hedge of a foreign currency exposure of a net investment
in a foreign operation.  The accounting for changes in the fair value of a
derivative (that is, gains and losses) depends on the intended use of the
derivative and the resulting designation.  In June 1999, the Financial
Accounting Standards Board issued SFAS No. 137 which delayed the adoptions of
SFAS No. 133 for all fiscal quarters of all fiscal years beginning after June
15, 2000.  Management of TBI does not expect that the adoption of SFAS No. 133
will have a material impact on TBI's financial position, results of operation,
or liquidity.

                         Independent Auditor's Report


The Board of Directors
Texas Bancshares, Inc. and Subsidiaries
San Antonio, Texas

We have audited the accompanying consolidated balance sheets of Texas
Bancshares, Inc. and Subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income and comprehensive income,
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1998. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Texas
Bancshares, Inc. and Subsidiaries as of December 31, 1998 and 1997, and the
consolidated results of their operations and their cash flows for the three-year
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

           Notes to Consolidated Financial Statements - (Continued)
                       (000's omitted from tabular data)

(1)      Summary of Organization and Significant Accounting Policies
         -----------------------------------------------------------

         Organization
         ------------

         The consolidated financial statements include the accounts of TBI, Inc.
         (Parent Company) and its wholly-owned subsidiaries, First National Bank
         of South Texas (FNB), Bank of South Texas (BOST), and Texas Bancshares
         Subsidiary Corporation (Subsidiary), collectively called the Company.
         All significant intercompany accounts and transactions have been
         eliminated.

         The financial statements have been prepared in accordance with
         generally accepted accounting principles. In preparing the financial
         statements, management is required to make estimates and assumptions
         that affect the reported amounts of assets and liabilities as of the
         dates of the balance sheets and income and expenses for the periods.
         Actual results could differ significantly from those estimates.
         Material estimates that are particularly susceptible to significant
         change in the near-term relate to the determination of the allowance
         for loan losses.

         The Company is engaged in the business of banking, including the
         acceptance of checking and savings deposits and the making of
         residential, commercial, real estate, and consumer loans to customers
         principally located in Nueces, Wilson, Bexar, Atascosa and Jim Wells
         counties in south Texas. Although the loan portfolio is diversified, a
         substantial portion of its debtors' ability to honor their loans is
         dependent upon the economic conditions in the area, especially in the
         agricultural and commercial business sectors. The Company competes for
         deposits and loans principally with other commercial banks, savings and
         loan associations and credit unions in the above mentioned counties. In
         addition, the Company is subject to the regulations of certain Federal
         agencies and undergoes periodic examinations by those regulatory
         authorities. Such agencies may require certain standards or impose
         certain limitations based on their judgments or changes in laws and
         regulations. Also, the Company's investment portfolio is directly
         impacted by fluctuations in market interest rates.

         The accounting and reporting policies of the Company conform to
         generally accepted accounting principles and to general practices
         within the banking industry. The following is a description of the more
         significant of those policies.

         Cash Equivalents
         ----------------

         For purposes of the consolidated statements of cash flows, the Company
         considers cash equivalents to be cash on hand, cash items in process,
         amounts due from banks, and Federal funds sold.

         Securities Held-to-Maturity and Securities Available-for-Sale
         -------------------------------------------------------------

         The Company classifies debt securities, including mortgage-backed
         securities, as either held-to-maturity or available-for-sale. Debt
         securities classified as held-to-maturity are those which the Company
         has the positive intent and ability to hold until maturity. These
         securities are carried at amortized cost with premiums and discounts
         being amortized using the effective interest method over the estimated
         remaining life of the security. Securities classified as available-for-
         sale are carried at fair value with unrealized gains or losses (net of
         deferred income taxes) reflected in stockholders' equity. Gains and
         losses recognized on the sale of securities are based on the specific
         identification method.

                                      F-7
<PAGE>

                    TEXAS BANCSHARES, INC. AND SUBSIDIARIES
           Notes to Consolidated Financial Statements - (Continued)
                       (000's omitted from tabular data)

         Mortgage-backed securities represent participating interests in pools
         of long-term first mortgage loans originated and serviced by the
         issuers of the securities. Mortgage-backed securities are either issued
         or guaranteed by the U. S. Government or its agencies. Mortgage-backed
         securities that are held-to-maturity are carried at unpaid principal
         balances, adjusted for unamortized premiums and unearned discounts.
         Premiums and discounts are amortized using the straight-line method
         over the remaining period to contractual maturity. The mortgage-backed
         securities that are available-for-sale are carried at fair value.
         Market interest rate fluctuations can affect the prepayment speed of
         principal and the market value and yield on the security.

         Loans
         -----

         Loans are reported at their principal amounts, net of unearned income
         and allowance for possible loan losses. Management, considering current
         information and events regarding the borrowers ability to repay their
         obligation, considers a loan to be impaired when it is probable that
         the Company will be unable to collect all amounts due according to the
         original contractual terms of the loan agreement. An impaired loan is
         to be measured based on the present value of expected future cash flows
         discounted at the loan's effective interest rate or at the loan's
         observable market price or the fair value of the collateral if the loan
         is collateral dependent.

         Interest Income on Loans
         ------------------------

         Interest income is accrued as earned on loans. When a loan, in
         management's judgment, becomes doubtful as to the collection of accrued
         interest income, it is placed on a non-accrual status. Interest
         payments received on non-accrual loans are recognized as income on a
         cash basis.

         Provision and Allowance for Possible Loan Losses
         ------------------------------------------------

         The provision for possible loan losses charged to operating expense is
         based on past loan loss experience and other factors which, in
         management's judgment, deserve current recognition in estimating
         possible loan losses. Such factors include the growth and composition
         of the loan portfolio, the relationship of the allowance to loans
         outstanding and economic conditions.

         Management believes that the allowance for possible loan losses is
         adequate. While management uses available information to recognize
         losses on loans, future additions to the allowance may be necessary
         based on changes in economic conditions. In addition, various
         regulatory agencies, as an integral part of their examination process,
         periodically review the Company's allowance for possible loan losses.
         Such agencies may require the Company to recognize additions to the
         allowance based on their judgments of information available to them at
         the time of their examination.

         Unearned Discount
         -----------------

         Loans are frequently made on a discount basis. The amount of the
         discount is subsequently included in interest income ratably over the
         term of the related loans under the sum-of-the-digits (Rule of 78th's)
         method which approximates the interest method.

                       (000's omitted from tabular data)

         Premises and Equipment
         ----------------------

         Premises and equipment are stated at cost less accumulated
         depreciation. Depreciation is calculated on a straight-line basis over
         the estimated useful lives of the assets. Expenditures for major
         renewals and betterments are capitalized and those for maintenance and
         repairs are charged to income as incurred.

         Other Real Estate Owned
         -----------------------

         Real estate acquired by foreclosure or deeds in lieu of foreclosure are
         carried at the lower of the recorded investment in the property or its
         fair value (determined by independent appraisal), less estimated costs
         to sell. Prior to foreclosure, the value of the underlying loan is
         written up or down to the fair value of the real estate to be acquired
         by a charge to the allowance for possible loan losses, if necessary.
         Any subsequent write-downs are charged against operating expenses. Net
         operating expenses of such properties and losses on their disposition
         are included in other operating expenses. If gains occur on
         disposition, the results are included in other operating income.

         Federal and State Income Taxes
         ------------------------------

         The Company files a consolidated Federal income tax return with BOST
         and FNB. The Parent Company, FNB and BOST each file separate franchise
         tax returns with the state of Texas. Subsidiary files a separate
         franchise tax return in Delaware. The Company accounts for income taxes
         under the asset and liability method which requires that deferred
         income taxes be recognized for the tax consequences of temporary
         differences (differences between the financial statement carrying
         amount and the tax bases of assets and liabilities) at the enacted
         statutory tax rates applicable to the future years in which those
         differences are expected to reverse.

         Intangible Assets
         -----------------

         Intangible assets include goodwill and organizational costs. The
         goodwill represents the cost in excess of the fair market value on the
         acquisition of Floresville Bancshares, Inc. in 1988, the acquisition of
         certain assets and liabilities of the First National Bank of Poth (a
         branch of BOST) in 1991, the acquisition of certain assets and
         liabilities of the Alice branch of the First Federal Savings Bank (a
         branch of FNB) in 1993, the merger with State Bank of La Vernia (a
         branch of FNB) in 1995, the acquisition of certain assets and
         liabilities of the Pleasanton branch of Bank of America (a branch of
         FNB) in 1995, and the acquisition of certain assets and liabilities of
         the Floresville branch of Bank of America (a branch of BOST) in 1995.
         Amortization is on a straight-line basis over 15 years, 7 years, 15
         years, 15 years, 15 years and 15 years, respectively. The
         organizational costs were incurred to open the Alice, La Vernia,
         Pleasanton, Floresville, Corpus Christi, and San Antonio branches. The
         Company will adopt AICPA Statement of Position 98-5 "Reporting on the
         Costs of Start-Up Activities" during 1999. This Statement requires
         costs of start-up activities and organization costs to be expensed as
         incurred. The Company does not expect that adoption of this Statement
         will have a material impact on the Company's operations, liquidity, or
         financial condition.

         Impairment of Long-Lived Assets and for Long-Lived Assets to be
         ---------------------------------------------------------------
         Disposed Of
         -----------

         The Company accounts for long-lived assets in accordance with the
         provisions of Statement of Financial Accounting Standards No. 121
         (Statement 121), "Accounting for the Impairment of Long-Lived Assets
         and for Long-Lived Assets to be Disposed Of." Statement 121 requires
         that long-lived assets and certain identifiable intangibles be reviewed
         for impairment whenever events or circumstances indicate that the
         carrying amount of an asset may not be recoverable. Recoverability of
         assets to be held and used is measured by a comparison of the carrying
         amount of an asset to future net cash flows expected to be generated by
         the asset. If such assets are considered to be impaired, the impairment
         to be recognized is measured by the amount by which the carrying amount
         of the assets exceeds the fair value of the assets. Assets to be
         disposed of are reported at the lower of the carrying amount or fair
         value less costs to sell.

         Stock Options
         -------------

         The Company accounts for its stock option plan in accordance with
         Statement of Financial Accounting Standards No. 123 (Statement 123),
         "Accounting for Stock-Based Compensation". Statement 123 permits
         entities to recognize as expense over the vesting period the fair value
         of all stock-based awards on the date of grant. Alternatively,
         Statement 123 also allows entities to continue to apply the provisions
         of APB Opinion No. 25, "Accounting for Stock Issued to Employees," and
         related interpretations and provide pro forma net income and pro forma
         earnings per share disclosures for employee stock option grants made in
         1995 and future years as if the fair-value-based method defined in
         Statement 123 had been applied. The Company has elected to apply the
         provisions of APB Opinion No. 25 and provide the pro forma disclosure
         provisions of Statement 123. As such, compensation expense is recorded
         on the date of grant only if the current market price of the underlying
         stock exceeded the exercise price.

         Transfers and Servicing of Financial Assets and Extinguishments of
         ------------------------------------------------------------------
         Liabilities
         -----------

         Effective January 1, 1998, the Company adopted Statement of Financial
         Accounting Standards No. 125, (Statement 125) "Accounting for Transfers
         and Servicing of Financial Assets and Extinguishments of Liabilities"
         and Statement of Financial Accounting Standards No. 127, (Statement
         127) "Deferral of the Effective Date of Certain Provisions of FASB No.
         125." Statement 125 provides accounting and reporting standards for
         transfers and servicing of financial assets and extinguishment of
         liabilities based on consistent application of a financial-components
         approach that focuses on control. It distinguishes transfers of
         financial assets that are sales from transfers that are secured
         borrowings. Adoption of Statement 125 and 127 did not have a material
         impact on the Company's financial position, results of operations, or
         liquidity.

         Earnings Per Common Share Computations
         --------------------------------------

         Effective January 1, 1997, the Company adopted Statement of Financial
         Accounting Standards No. 128, (Statement 128) "Earnings per Share."
         Statement 128 specifies the computation, presentation, and disclosure
         requirements for earnings per share (EPS) and replaces primary EPS and
         fully diluted EPS on the face of the income statement for all entities
         with complex capital

                                      F-10

         structures and requires a reconciliation of the basic EPS computation
         to the diluted EPS. Basic EPS is calculated by dividing net income
         available to common shareholders, by the weighted average number of
         common shares outstanding. The computation of diluted EPS assumes the
         issuance of common shares for all dilutive potential common shares
         outstanding during the reporting period. The dilutive effect of stock
         options are considered in earnings per share calculations if dilutive,
         using the treasury stock method. Statement 128 is effective for
         financial statements issued for periods ending after December 15, 1997,
         including interim periods. All prior-period earnings per share data
         presented in the accompanying consolidated financial statements has
         been restated to conform to the requirements of Statement 128.

         Comprehensive Income
         --------------------

         In June 1997, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 130, ("Statement 130") "Reporting
         Comprehensive Income." Statement 130 establishes standards for
         reporting and display of comprehensive income and its components
         (revenues, expenses, gains, and losses) in a full set of general-
         purpose financial statements. Statement 130 requires that an enterprise
         (a) classify items of other comprehensive income by their nature in a
         financial statement and (b) display the accumulated balance of other
         comprehensive income separately from retained earnings and additional
         paid-in capital in the equity section of a statement of financial
         position. Statement 130 is effective for fiscal years beginning after
         December 15, 1997. The provisions of Statement 130 were adopted by the
         Company as of January 1, 1998. The adoption of Statement 130 did not
         have a material impact on the Company's financial position, results of
         operation, or liquidity.

         Reclassifications
         -----------------

         Certain 1996 and 1997 balances have been reclassified to conform to the
         1998 presentation. Such reclassifications had no effect on net income
         or total stockholders' equity.

(2)      Related Party Transactions
         --------------------------

         The Company has had, in the ordinary course of business, banking
         transactions (primarily loans) with officers, directors, and their
         affiliates. In management's opinion, all such transactions have been on
         substantially the same terms (including interest rates and collateral)
         as those prevailing for comparable transactions with others and have
         not included more than the normal risk of collectibility or other
         unfavorable features. The loans outstanding to officers and directors,
         including loans made to companies in which the officers and directors
         exercise control through direct and indirect ownership, were as
         follows:

                Balance at December 31, 1997                $ 1,566

          Management believes that realization of the deferred tax assets is
          more likely than not based on the expectation that such benefits will
          be utilized in future consolidated tax returns of the Company.

          The net deferred tax asset of $951,000 at June 30, 1999 (unaudited)
          and $271,000 and $207,000 at December 31, 1998 and 1997, respectively,
          is included in other assets. Included in other liabilities is federal
          income taxes payable of $176,000 at June 30, 1999 (unaudited) and
          $85,000 and $68,000 at December 31, 1998 and 1997, respectively.


(8)       Lines of Credit
          ---------------

          At June 30, 1999 (unaudited) and December 31, 1998, FNB and BOST had
          two unused Federal fund lines of credit for $2,500,000 each at one
          non-affiliated bank, expiring on December 31, 1999 and December 31,
          1998, respectively. FNB and BOST renewed the lines of credit that
          expired on December 31, 1998. The lines bear interest at the non-
          affiliate bank's Federal fund rate when drawn and are due on demand,
          but if no demand is made, then daily. The lines are unsecured. FNB and
          BOST have unused Federal fund lines of $5,000,000 and $2,500,000,
          respectively at another non-affiliated bank that expire on December
          31, 1999 and June 24, 1999, respectively. FNB and BOST renewed the
          lines of credit that expired on June 24, 1999. These lines bear
          interest at the non-affiliate bank's Federal fund rate when drawn and
          are due on demand, but if no demand is made, then daily. These lines
          are fully secured by securities available-for-sale (see note 4).
          Additionally, as members of the Federal Home Loan Bank (FHLB), the
          Banks were eligible to borrow a total of $22,997,000 at June 30, 1999
          (unaudited) and $22,929,000 at December 31, 1998, if secured with 1-4
          family residential loans. $3,373,000

                       (000's omitted from tabular data)

              and $2,935,000, respectively were outstanding under the lines of
              credit at the FHLB at June 30, 1999 (unaudited), and December 31,
              1998.

(9)      401(K) / Profit Sharing Plan / Stock Options
         --------------------------------------------

         The Company has a 401(K) / profit sharing plan administered by the
         Parent Company, which covers all eligible employees working at least
         500 hours per year, and allows the Company to match the employees'
         contributions, and to contribute a discretionary percentage of earnings
         which by law may not exceed 15% of the total qualifying employee
         compensation. Vesting of Company contributions occurs over a 6-year
         period with distribution of Plan assets at retirement or termination of
         employment. The Company's contributions to the Plan charged to
         operating expenses were $108,000 for the six months ended June 30, 1999
         (unaudited), $137,000, $124,000, and $0 for December 31, 1998, 1997 and
         1996, respectively.

         During 1996, the Company adopted a Stock Option Plan with 100,000
         shares of common stock, no par value available for issuance under the
         plan. In 1997, the Company adjusted the number of shares available for
         issuance to 200,000 due to a two-for-one stock split.

         No stock options were granted or exercised in 1998 or during the six
         months ending June 30, 1999; however, 750 stock options were forfeited
         during the period ended June 30, 1999 (unaudited). As of June 30, 1999
         (unaudited), and December 31, 1998, the weighted average for value of
         all options outstanding was $22.27 and $9.25 per option, respectively,
         based upon the Modified Black-Scholes American Option pricing model.
         Input variables used in the model included a risk free interest rate at
         June 30, 1999 (unaudited) of 5.1% to 5.9%, and 4.6% and 4.8% for 1998.
         An expected volatility factor of 38.5% and 32.5% were used for June 30,
         1999

         (unaudited) and December 31, 1998, respectively. An estimated option
         life of 1.8 to 8.4 years was used for June 30, 1999 (unaudited) and 2
         to 9 years was used for December 31, 1998. The pro forma impact on
         income assumes no options will be forfeited. The pro forma effects may
         not be representative of the effects on reported net income for future
         years as most of the Company's employee stock options have an option
         life of 10 years.

(11)     Financial Instruments with Off-Balance Sheet Risk and Other
         -----------------------------------------------------------
         Contingent Liabilities
         ----------------------

         In the normal course of business, various commitments and contingent
         liabilities are outstanding such as guarantees, standby letters of
         credit, commitments to extend credit and various financial instruments
         with off-balance sheet risk, that are not reflected in the accompanying
         consolidated financial statements. Financial instruments with
         off-balance sheet risk involve elements of credit risk, interest rate
         risk, liquidity risk and market risk.

                                     F-21

                    TEXAS BANCSHARES, INC. AND SUBSIDIARIES
           Notes to Consolidated Financial Statements - (Continued)
                       (000's omitted from tabular data)


         The Company's exposure to credit loss in the event of nonperformance by
         the other party on such financial instruments is represented by the
         contractual amount of the instruments. The Company uses the same credit
         policies in making commitments and conditional obligations as it does
         for on-balance sheet instruments. The Company controls the credit risk
         of these transactions through credit approvals, limits, and monitoring
         procedures.

         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 the 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 Company evaluates each customer's creditworthiness on
         a case-by-case basis. The amount of collateral obtained, if deemed
         necessary by the Company upon extension of credit, is based on
         management's credit evaluation of the counter-party. Collateral held
         varies, but may include residential and commercial real estate,
         certificates of deposit, accounts receivable, and inventory. At June
         30, 1999 (unaudited), December 31, 1998 and 1997, the Company had
         $57,916,000, $56,935,000 and $46,904,000 of outstanding loan
         commitments, respectively.

         Letters of credit are written conditional commitments issued by the
         Company to guarantee the performance of a customer to a third party.
         The credit risk involved in issuing letters of credit is essentially
         the same as that involved in extending loan facilities to customers. At
         June 30, 1999 (unaudited), December 31, 1998 and 1997, the Company had
         $1,599,000, $1,419,000 and $1,296,000, under standby letters of credit,
         respectively. Management anticipates no material losses as a result of
         these transactions.

 (12)    Fair Value of Financial Instruments
         -----------------------------------

         Statement of Financial Accounting Standards No. 107 (Statement 107),
         "Disclosure about Fair Value of Financial Instruments," requires that
         the Company disclose estimated fair values for its financial
         instruments. Fair value estimates, methods, and assumptions are set
         forth below for the Company's financial instruments.

         Cash and Short-Term Investments
         -------------------------------

         For those short-term instruments, the carrying amount is a reasonable
         estimate of fair value.

         Securities Held-to-Maturity and Securities Available-for-Sale
         -------------------------------------------------------------

         For securities available-for-sale (which includes U.S. Treasury, other
         U.S. Government agencies, corporations, mortgage-backed securities and
         other securities), and securities held-to-maturity (which includes
         obligations of state and political subdivisions and collateralized
         mortgage obligations (CMO's)), fair values are based on quoted market
         prices or dealer quotes. For other securities, fair value equals quoted
         market price, if available. If a quoted market price is not available,
         fair value is estimated using quoted market prices for similar
         securities.

         Loans
         -----

         Fair values are estimated for portfolios of loans with similar
         financial characteristics. Loans are segregated by type such as
         commercial, real estate, and consumer loans as outlined by the
         regulatory reporting guidelines. Each loan category is further
         segmented into fixed and adjustable rate interest terms and by
         performing and nonperforming categories.

                       (000's omitted from tabular data)

         The fair value of loans is calculated by discounting scheduled cash
         flows through the estimated maturity using estimated market discount
         rates that reflect the credit and interest rate risk inherent in the
         loan. The estimate of maturity is based on the Company's historical
         experience and average days to maturity. The discount rates reflect the
         term structure of interest based on the Treasury yield curve, a risk
         premium for reported credit quality characteristics, expense allocation
         and allowances for prepayment risk.

         Deposits Liabilities
         --------------------

         Under Statement 107, the fair value of deposits with no stated
         maturity, such as non-interest bearing demand deposits, savings, and
         NOW accounts, and money market and checking accounts, is equal to the
         amount payable on demand. The fair value of certificates of deposit is
         based on the discounted value of contractual cash flows. The discount
         rate is based on the Treasury yield curve adjusted for a risk premium,
         expense allocation and allowances for prepayment, as calculated on the
         day of the expected future cash flow.

         Commitments to Extend Credit, Standby Letters of Credit, and Financial
         ----------------------------------------------------------------------
         Guarantees Written
         ------------------

         Commitments to extend credit, standby letters of credit, and financial
         guarantees written are principally at current interest rates and
         therefore have no material associated fair value.

         The estimated fair values of the Company's financial instruments are as
         follows:

         Fair value estimates are made at a specific point in time, based on

         discount that could result from offering for sale at one time the
         Company's entire holdings of a particular financial instrument. Because
         no market exists for a significant portion of the Company's financial
         instruments, fair value estimates are based on judgments regarding
         future expected loss experience, current economic conditions, risk
         characteristics of various financial instruments, and other factors.
         These estimates are subjective in nature and involve uncertainties and
         matters of significant judgment and therefore cannot be determined with
         precision. Changes in assumptions could significantly affect the
         estimates.

         Fair value estimates are based on existing on and off-balance sheet
         financial instruments without attempting to estimate the value of
         anticipated future business and the value of assets and liabilities
         that are not considered financial instruments. Other significant assets
         and liabilities that are not considered financial assets or liabilities
         include the deferred tax assets and liabilities, premises and
         equipment, and intangible and other assets. In addition, the tax
         ramifications related to the realization of the unrealized gains and
         losses can have a significant effect on fair value estimates and have
         not been considered in the estimates.

(13)     Dividend Restrictions / Capital Ratios
         --------------------------------------

         Dividend Restrictions
         ---------------------

         Bank regulatory agencies limit the amount of dividends which banks can
         pay without obtaining prior approval from such agencies. At June 30,
         1999 (unaudited), the aggregate amount legally available to be
         distributed to the Company from BOST and FNB as dividends was
         approximately $5,948,000. At December 31, 1998 and 1997, the aggregate
         amount legally available to be distributed to the Company from BOST and
         FNB as dividends was approximately $3,874,000 and $4,807,000.

         Capital Ratios
         --------------

         The Company and FNB and BOST 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 - action by regulators that, if
         undertaken, could have a direct material effect on the Company's
         consolidated financial statements. Under capital adequacy guidelines
         and the regulatory framework for prompt corrective action, the Company
         and FNB and BOST must meet specific capital guidelines that involve
         quantitative measures of the Company's, FNB's and BOST's assets,
         liabilities, and certain off-balance-sheet items as calculated under
         regulatory accounting practices. The Company's and FNB and BOST's
         capital amounts and classifications 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 Company and FNB and BOST to maintain minimum
         amounts and ratios (set forth in the table below) of total and Tier I
         capital (as defined in the regulations) to risk-weighted assets (as
         defined), and of Tier I capital (as defined) to average assets (as
         defined). Management believes, as of June 30, 1999 and December 31,
         1998, that the Company and FNB and BOST meet all capital adequacy
         requirements to which they are subject.

         As of June 30, 1999 and December 31, 1998, the most recent notification
         from the Office of the Comptroller of the Currency and the Federal
         Deposit Insurance Corporation categorized FNB and BOST, respectively,
         as well capitalized under the regulatory framework for prompt
         corrective action. To be categorized as well capitalized, FNB and BOST
         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 since that notification, that management believes have changed
         FNB's or BOST's category.

(14)     Litigation
         ----------

         The Company is involved in legal proceedings that are in various stages
         of litigation by the Company and its legal counsel. These actions
         allege claims on a variety of theories and claim substantial actual and
         punitive damages. Management of the Company has determined, based on
         discussions with its counsel, that the risk of any material loss in
         such actions, individually or in the aggregate, is remote or the
         damages sought, even if fully recovered, would not be considered
         material. However, many of these matters are in various stages of
         proceedings and further developments could cause Management to revise
         its assessment of these matters.

(15)     Earnings Per Common Share
         -------------------------

         Basic earnings per share was computed by dividing net income available
         to common shareholders by the weighted average number of shares of
         common stock outstanding during the year, retroactively adjusted for
         stock splits effected as a stock dividend.

         Diluted earnings per share was computed by dividing net income by the
         weighted average number of shares of common stock and common stock
         equivalents outstanding during the year, retroactively adjusted for
         stock splits effected as a stock dividend. The diluted earnings per
         share computations include the effects of common stock equivalents
         applicable to stock option contracts.

         The table below presents a reconciliation of basic and diluted earnings
         per share computations for June 30, 1999 and 1998, and the years ended
         December 31, 1998, 1997 and 1996. (Dollars in thousands, except per
         share data.)

(16)     Year 2000 Issues (unaudited)
         ----------------------------

         In 1997, the Company initiated a plan ("Plan") to identify, assess, and
         remediate "Year 2000" issues within each of its significant computer
         programs and certain equipment which contain micro-processors. The Plan
         is addressing the issue of computer programs and embedded computer
         chips being able to distinguish between the year 1900 and the year
         2000, if a program or chip uses only two digits rather than four to
         define the applicable year. The Company has divided the Plan into five
         major phases - assessment, planning, conversion, implementation and
         testing. After completing the assessment and planning phases in 1997,
         the Company is currently in the conversion, implementation and testing
         phases. Systems which have been determined not to be Year 2000
         compliant are being either replaced or reprogrammed, and thereafter
         tested for Year 2000 compliance. In 1997, the Company completed the
         assessment and planning phases. In 1998, the Company conducted testing
         on critical systems followed by any necessary implementation or
         conversion processes. Systems which have been determined not to be Year
         2000 compliant are being either replaced or reprogrammed, and
         thereafter tested for Year 2000 compliance. At mid-1999, the Company
         had completed all testing and implementation phases for critical
         systems. The Company had also completed written contingency plans and
         tested the plans accordingly.

         The Company is in the process of identifying and contacting critical
         suppliers and customers whose computerized systems interface with the
         Company's systems, regarding their plans and progress in addressing
         their Year 2000 issues. The Company has received varying information
         from such third parties on the state of compliance or expected
         compliance. Contingency plans are being developed in the event that any
         critical supplier or customer is not compliant.

         The failure to correct a material Year 2000 problem could result in an
         interruption in, or a failure of, certain normal business activities or
         operations. Such failures could materially and adversely affect the
         Company's operations, liquidity and financial condition. Due to the
         general uncertainty inherent in the Year 2000 problem, resulting in
         part from the uncertainty of the Year 2000 readiness of third-party
         suppliers and customers, the Company is unable to determine at this
         time whether the consequences of Year 2000 failures will have a
         material impact on the Company's operations, liquidity or financial
         condition.

premises and the mutual covenants and agreements contained herein, the parties

     (a)  Merger.  Subject to the terms and conditions contained herein, a
          ------
wholly-owned subsidiary of Wells Fargo (the "Merger Co.") will be merged by
statutory merger with and into TBI pursuant to the Merger Agreement, with TBI as
the surviving corporation, in which merger each share of TBI Common Stock
outstanding immediately prior to the Effective Time of the Merger (as defined
below), other than shares as to which statutory dissenters' appraisal rights
have been exercised, will be exchanged for the number of shares of Wells Fargo
Common Stock determined by dividing the Adjusted Wells Fargo Shares (as defined
below) by the number of shares of TBI Common Stock then outstanding.

     The "Adjusted Wells Fargo Shares" shall be a number equal to the Aggregate
Share Amount divided by the Wells Fargo Measurement Price.  The "Wells Fargo
Measurement Price" is defined as the average of the closing prices of a share of
Wells Fargo Common Stock as reported on the consolidated tape of the New York
Stock Exchange during the period of 10 trading days ending on the day
immediately preceding the meeting of shareholders required by paragraph 4(c) of
this Agreement.  The "Aggregate Share Amount" shall be $68,500,000 plus the
aggregate exercise price of all Options exercised by cash payments between the
date hereof and the day immediately prior to the Closing Date minus the Cash
Surrender Amount.  The "Cash Surrender Amount" shall equal the difference
between (i) the product of (A) the "Fair Market Value Per Share" multiplied by
(B) the number of Redeemed Options , minus (ii) the aggregate
<PAGE>

exercise price of all Redeemed Options. "Fair Market Value Per Share" shall mean
$34.2988. "Option" has the meaning given it in paragraph 2(c).

     (b)  Wells Fargo Common Stock Adjustments.  If, between the date hereof and
          ------------------------------------
the Effective Time of the Merger, shares of Wells Fargo Common Stock shall be
changed into a different number of shares or a different class of shares by
reason of any reclassification, recapitalization, split-up, combination,
exchange of shares or readjustment, or if a stock dividend thereon shall be
declared with a record date within such period (a "Common Stock Adjustment"),
then the number of shares of Wells Fargo Common Stock into which a share of TBI
Common Stock shall be converted pursuant to subparagraph (a), above, will be
appropriately and proportionately adjusted so that the number of such shares of
Wells Fargo Common Stock into which a share of TBI Common Stock shall be
converted will equal the number of shares of Wells Fargo Common Stock which
holders of shares of TBI Common Stock would have received pursuant to such
Common Stock Adjustment had the record date therefor been immediately following
the Effective Time of the Merger.

     (c)  Fractional Shares.  No fractional shares of Wells Fargo Common Stock
          -----------------
and no certificates or scrip certificates therefor shall be issued to represent
any such fractional interest, and any holder thereof shall be paid an amount of
cash equal to the product obtained by multiplying the fractional share interest
to which such holder is entitled by the average of the closing prices of a share
of Wells Fargo Common Stock as reported by the consolidated tape of the New York
Stock Exchange for each of the ten (10) trading days ending on the day
immediately preceding the meeting of shareholders required by paragraph 4(c) of
this Agreement.

     (d)  Mechanics of Closing Merger.  Subject to the terms and conditions set
          ---------------------------
forth herein, the Merger Agreement shall be executed and it or Articles of
Merger or a Certificate of Merger shall be filed with the Secretary of State of
the State of Texas within ten (10) business days following the satisfaction or
waiver of all conditions precedent set forth in Sections 6 and 7 of this
Agreement or on such other date as may be agreed to by the parties (the "Closing
Date").  Each of the parties agrees to use its best efforts to cause the Merger
to be completed as soon as practicable after the receipt of final regulatory
approval of the Merger and the expiration of all required waiting periods.  The
time that the filing referred to in the first sentence of this paragraph is made
is herein referred to as the "Time of Filing."  The day on which such filing is
made and accepted is herein referred to as the "Effective Date of the Merger."
The "Effective Time of the Merger" shall be 11:59 p.m., Austin, Texas time, on
the Effective Date of the Merger.  At the Effective Time of the Merger on the
Effective Date of the Merger, the separate existence Merger Co. shall cease and
Merger Co. will be merged with and into TBI pursuant to the Merger Agreement.

     The closing of the transactions contemplated by this Agreement and the
Merger Agreement (the "Closing") shall take place on the Closing Date at the
offices of Wells Fargo, Norwest Center, Sixth and Marquette, Minneapolis,
Minnesota.

     2.  Representations and Warranties of TBI.  TBI represents and warrants to
Wells Fargo as follows, subject to the exceptions set forth in the schedules
attached hereto (whenever representations or warranties of TBI are qualified by
the knowledge or best knowledge of TBI, knowledge shall mean actual knowledge of
the executive officers and officers having the title Vice President or better
and directors of TBI and of the "TBI Subsidiaries" (defined below) after due
inquiry and investigation:

     (a)  Organization and Authority.  TBI is a corporation duly organized,
          --------------------------
validly existing and in good standing under the laws of the State of Texas, is
duly qualified to do business and is in good standing in all jurisdictions where
its ownership or leasing of property or the conduct of its business requires it
to be so qualified and failure to be so qualified would have a material adverse
effect on TBI and the TBI Subsidiaries (defined below) taken as a whole, and has
corporate power and authority to own its properties and assets and to carry on
its business as it is now being conducted.  TBI is registered as a bank holding
company with the Federal Reserve Board under the Bank Holding Company Act of
1956, as amended (the "BHC Act").  TBI has furnished Wells Fargo true and
correct copies of its articles of incorporation and by-laws, as amended.

     (b)  TBI's Subsidiaries.  Schedule 2(b) sets forth a complete and correct
          ------------------
list of all TBI subsidiaries as of the date hereof (individually a "TBI
Subsidiary" and collectively the "TBI Subsidiaries"), all shares of the
outstanding capital stock of each of which, except as set forth on Schedule
2(b), are owned directly or indirectly by TBI.  No equity security of any TBI
Subsidiary is or may be required to be issued by reason of any option, warrant,
scrip, preemptive right, right to subscribe to, call or commitment of any
character whatsoever relating to, or security or right convertible into, shares
of any capital stock of such subsidiary, and there are no contracts,
commitments, understandings or arrangements by which any TBI Subsidiary is bound
to issue additional shares of its capital stock, or any option, warrant or right
to purchase or acquire any additional shares of its capital stock.  Subject to
12 U.S.C. (S) 55 (1982) and the Texas Business Corporation Act, all of such
shares so owned by TBI are fully paid and nonassessable and are owned by it free
and clear of any lien, claim, charge, option, encumbrance or agreement with
respect thereto.  Each TBI Subsidiary is a corporation, Texas state banking
association, or national banking association duly organized, validly existing,
duly qualified to do business and in good standing under the laws of its
jurisdiction of incorporation, and has corporate power and authority to own or
lease its properties and assets and to carry on its business as it is now being
conducted.  Except as set forth on Schedule 2(b), TBI does not own beneficially,
directly or indirectly, more than 5% of any class of equity securities or
similar interests of any corporation, bank, business trust, association or
similar organization, and is not, directly or indirectly, a partner in any
partnership or party to any joint venture.

     (c)  Capitalization.  The authorized capital stock of TBI consists of
          --------------
10,000,000 shares of common stock, no par value, and 1,000,000 shares of
preferred stock, no par value, of which as of the close of business on December
31, 1998, 1,966,536 shares of common stock and no shares of preferred stock were
outstanding and 36,864 shares of common stock were held in the treasury.  The
maximum number of shares of TBI

                                      A-3
<PAGE>

Common Stock (assuming for this purpose that phantom shares and other share-
equivalents constitute TBI Common Stock) that would be outstanding as of the
Effective Date of the Merger if all options, warrants, conversion rights and
other rights with respect thereto, were exercised is 2,026,036. All of the
outstanding shares of capital stock of TBI have been duly and validly authorized
and issued and are fully paid and nonassessable. Except as set forth in Schedule
2(c), there are no outstanding subscriptions, contracts, conversion privileges,
options, warrants, calls, preemptive rights or other rights obligating TBI or
any TBI Subsidiary to issue, sell or otherwise dispose of, or to purchase,
redeem or otherwise acquire, any shares of capital stock of TBI or any TBI
Subsidiary. As of the date hereof, the total number of options and the exercise
price thereof issued pursuant to the 1996 Texas Bancshares, Inc. Stock Option
Plan, as amended as of October 20, 1997 (the "Option Plan"), of the Options
granted thereunder ("Options") is as set forth on Schedule 2(c). The Option Plan
has not been amended or modified since October 20, 1997. Except as set forth on
Schedule 2(c), since December 31, 1998 no shares of TBI capital stock have been
purchased, redeemed or otherwise acquired, directly or indirectly, by TBI or any
TBI Subsidiary and no dividends or other distributions have been declared, set
aside, made or paid to the shareholders of TBI.

     (d)  Authorization.  TBI has the corporate power and authority to enter
          -------------
into this Agreement and the Merger Agreement and, subject to any required
approvals of its shareholders, to carry out its obligations hereunder and
thereunder. The execution, delivery, and performance of this Agreement and the
Merger Agreement by TBI and the consummation of the transactions contemplated
hereby and thereby have been duly authorized by the Board of Directors of TBI.
Subject to such approvals of shareholders and of government agencies and other
governing boards having regulatory authority over TBI as may be required by
statute or regulation, this Agreement and the Merger Agreement are valid and
binding obligations of TBI enforceable against TBI in accordance with their
respective terms.

     Except as set forth on Schedule 2(d), neither the execution, delivery and
performance by TBI of this Agreement or the Merger Agreement, nor the
consummation of the transactions contemplated hereby and thereby, nor compliance
by TBI with any of the provisions hereof or thereof, will (i) violate, conflict
with, or result in a breach of any provision of, or constitute a default (or an
event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination of, or accelerate the performance required
by, or result in a right of termination or acceleration of, or result in the
creation of, any lien, security interest, charge or encumbrance upon any of the
properties or assets of TBI or any TBI Subsidiary under any of the terms,
conditions or provisions of (x) its articles of incorporation or by-laws or (y)
any material note, bond, mortgage, indenture, deed of trust, license, lease,
agreement or other instrument or obligation to which TBI or any TBI Subsidiary
is a party or by which it may be bound, or to which TBI or any TBI Subsidiary or
any of the properties or assets of TBI or any TBI Subsidiary may be subject, or
(ii) subject to compliance with the statutes and regulations referred to in the
next paragraph, to the best knowledge of TBI, violate any judgment, ruling,
order, writ, injunction, decree, statute, rule or regulation applicable to TBI
or any TBI Subsidiary or any of their respective properties or assets.

Act"), the Securities Exchange Act of 1934 and the rules and regulations
thereunder (the "Exchange Act"), the securities or blue sky laws of the various
states or filings, consents, reviews, authorizations, approvals or exemptions

approval of, any public body or authority is necessary for the consummation by
TBI of the transactions contemplated by this Agreement and the Merger Agreement.

the TBI Subsidiaries as of December 31, 1998 and 1997 and related consolidated
statements of income, shareholders' equity and comprehensive income, and cash

at the dates and the consolidated results of operations and cash flows of TBI
and the TBI Subsidiaries for the periods stated therein.

     (f)  Reports.  Since December 31, 1994, TBI and each TBI Subsidiary has

banking authorities.  All such reports and statements filed with any such
regulatory body or authority are collectively referred to herein as the "TBI

material respects with all the rules and regulations promulgated by the SEC, the
Federal Reserve Board, the FDIC, the Comptroller and applicable state securities
or banking authorities, as the case may be, and did not contain any untrue
statement of a material fact or omit to state a material fact required to be

encumbrances or similar restrictions to all the real and personal property
reflected in TBI's consolidated balance sheet as of December 31, 1998 for the
period then ended, and all real and personal property acquired since such date,
except such real and personal property as has been disposed of in the ordinary
course of business. All leases of real property and all other leases material to
TBI or any TBI Subsidiary pursuant to which TBI or such TBI Subsidiary, as
lessee, leases real or personal property, which leases are described on Schedule
2(g), are valid and effective in accordance with their respective terms, and
there is not, under any such lease, any material existing default by TBI or such
TBI Subsidiary or any event which, with notice or lapse of time or both, would
constitute such a material default. Substantially all TBI's and each TBI
Subsidiary's buildings and equipment in regular use have been well maintained
and are in good and serviceable condition, reasonable wear and tear excepted.

     (h)  Taxes.  Each of TBI and the TBI Subsidiaries has filed all federal,
          -----

required to be filed by it, and paid or made adequate provision on its balance
sheet for all taxes owed by it, including those with respect to income,
withholding, social security, unemployment, workers compensation, franchise, ad
valorem, premium, excise and sales taxes, and no taxes shown on such returns to
be owed by it or assessments received by it are delinquent.  The federal income

routine audit by the Internal Revenue Service closed because of the statute of
limitations, and no claims for additional taxes for such fiscal years are
pending.  Except only as set forth on Schedule 2(h), (i) neither TBI nor any TBI

withhold from amounts owing to employees, creditors or other third parties.  The
consolidated balance sheet as of December 31, 1998, referred to in paragraph
2(e) hereof, includes adequate provision for all accrued but unpaid federal,

          --------------------------
change in the business, financial condition or results of operations of TBI or
any TBI Subsidiary, which has had, or may reasonably be expected to have, a
material adverse effect on the business, financial condition or results of
operations of TBI and the TBI Subsidiaries taken as a whole (other than changes
in banking laws or regulations, or interpretations thereof, that affect the
banking industry generally or changes in the general level of interest rates).

     any TBI Subsidiary may carry on its business (other than as may be required
     by law or applicable regulatory authorities);

               (v)    any other contract or agreement which is a "material
     contract" within the meaning of Item 601(b)(10) of Regulation S-K; or

               (vi)   any lease with annual rental payments aggregating $10,000

                                      A-7
<PAGE>

aggregate, will not have, or cannot reasonably be expected to have, a material
adverse effect on the business, financial condition or results of operations of
TBI and the TBI Subsidiaries taken as a whole.

     (l)  Insurance.  TBI and each TBI Subsidiary are presently insured, and
          ---------
during each of the past five calendar years (or during such lesser period of
time as TBI has owned such TBI Subsidiary) have been insured, for reasonable
amounts with financially sound and reputable insurance companies against such
risks as companies engaged in a similar business would, in accordance with good
business practice, customarily be insured and has maintained all insurance
required by applicable law and regulation.

     (m)  Compliance with Laws.  TBI and each TBI Subsidiary have all permits,
          --------------------
licenses, authorizations, orders and approvals of, and have made all filings,
applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to own
or lease its properties and assets and to carry on its business as presently

all such permits, licenses, certificates of authority, orders and approvals are
in full force and effect and, to the best knowledge of TBI, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current.  The conduct by TBI and each TBI Subsidiary of
its business and the condition and use of its properties does not violate or
infringe, in any respect material to any such business, any applicable domestic
(federal, state or local) or foreign law, statute, ordinance, license or
regulation.  Neither TBI nor any TBI Subsidiary is in default under any order,
license, regulation or demand of any federal, state, municipal or other
governmental agency or with respect to any order, writ, injunction or decree of
any court.  Except for statutory or regulatory restrictions of general
application and except as set forth on Schedule 2(m), no federal, state,
municipal or other governmental authority has placed any restriction on the
business or properties of TBI or any TBI Subsidiary which reasonably could be
expected to have a material adverse effect on the business or properties of TBI
and the TBI Subsidiaries taken as a whole.

     (n)  Labor.  No work stoppage involving TBI or any TBI Subsidiary is
          -----
pending or, to the best knowledge of TBI, threatened.  Neither TBI nor any TBI
Subsidiary is involved in, or to the knowledge of TBI threatened with or
affected by, any labor dispute, arbitration, lawsuit or administrative
proceeding which could materially and adversely affect the business of TBI or
such TBI Subsidiary.  Employees of TBI and the TBI Subsidiaries are not

          -------------------------------------
Schedule 2(o), to the best knowledge of TBI no officer or director of TBI or any
TBI Subsidiary, or any "associate" (as such term is defined in Rule l4a-1 under
the Exchange Act) of any such officer or director, has any interest in any
material contract or property (real or personal), tangible or intangible, used
in or pertaining to the business of TBI or any TBI Subsidiary.

                                      A-8

     Security Act of 1974, as amended, and the term "Plan" or "Plans" means all
     employee benefit plans as defined in Section 3(3) of ERISA, and all other

     employees, workers' compensation, disability benefits, supplemental
     unemployment benefits, vacation benefits, retirement benefits, severance or
     termination of employment benefits, life, health, death, disability or
     accidental benefits.

     Exchange Commission) required in connection with each Plan have been timely
     made; (c) all disclosures and notices required by law or Plan provisions to
     be given to participants and beneficiaries in connection with each Plan
     have been properly and timely made; (d) there are no actions, suits or
     claims pending, other than routine uncontested claims for benefits with
     respect to each Plan; and (e) each Plan intended to be qualified under
     Section 401(a) of the Code has received a favorable determination letter
     from the Internal Revenue Service stating that the Plan (including all
     amendments) is tax qualified under Section 401(a) of the Code and TBI knows
     of no reason that any such Plan is not qualified within the meaning of
     Section 401(a) of the Code and knows of no reason that each related Plan
     trust is not exempt from taxation under Section 501(a) of the Code.

     contributions, premium payments and other payments due in the current
     fiscal year but not made as of the date of this Agreement; (c) no
     contribution, premium payment or other payment has been made in support of
     any Plan that is in excess of the allowable deduction for federal income
     tax purposes for the year with respect to which the contribution was made
     (whether under Sections 162, 280G, 404, 419, 419A of the Code or
     otherwise); and (d) with respect to each Plan that is subject to Section
     301 of ERISA or Section 412 of the Code, TBI is not liable for any
     accumulated funding deficiency as that term is defined in Section 412 of
     the Code and the projected benefit obligations determined as of the date of
     this Agreement do not exceed the assets of the Plan.

          --------------------------------
properly administered in all material respects and which could reasonably be
expected to be material to the financial condition of TBI and the TBI
Subsidiaries taken as a whole all accounts for which it acts as a fiduciary,
including but not limited to accounts for which it serves as a trustee, agent,
custodian, personal representative, guardian, conservator or investment advisor,
in accordance with the terms of the governing documents and applicable state and
federal law and regulation and common law. To the knowledge of TBI, neither TBI,
any TBI Subsidiary, nor any director, officer or employee of TBI or any TBI

TBI or any TBI Subsidiary material obligations other than with respect to those
arising in the ordinary course of the banking business of the TBI Subsidiaries
are in compliance therewith in all material respects.

     (v)  Environmental Liability.  There is no legal, administrative, or other
          -----------------------

relating to the release of hazardous substances as defined under any local,

without limitation, the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended ("CERCLA"), pending or to the best of TBI's
knowledge, threatened against TBI or any TBI Subsidiary the result of which has
had or could reasonably be expected to have a material adverse effect upon TBI
and the TBI Subsidiaries taken as a whole; to the best of TBI's knowledge there
is no reasonable basis for any such proceeding, claim or action; and to the best
of TBI's knowledge neither TBI nor any TBI Subsidiary is subject to any
agreement, order, judgment, or decree by or with any court, governmental
authority or third party imposing any such environmental liability. TBI has

studies and other related information in its possession with respect to each
bank facility and each non-residential OREO property.

     from the Internal Revenue Service stating that the Wells Fargo Plan

          -----------
default, nor has any event occurred which, with the passage of time or the
giving of notice, or both, would constitute a default under any material
agreement, indenture, loan agreement or other instrument to which it is a party
or by which it or any of its assets is bound or to which any of its assets is
subject, the result of which has had or could reasonably be expected to have a
material adverse effect upon Wells Fargo and its subsidiaries taken as a whole.
To the best of Wells Fargo's knowledge, all parties with whom Wells Fargo or any
Wells Fargo Subsidiary has material leases, agreements or contracts or who owe
to Wells Fargo or any Wells Fargo Subsidiary material obligations other than
with respect to those arising in the ordinary course of the banking business of
the Wells Fargo Subsidiaries are in compliance therewith in all material
respects.

     (s)  Environmental Liability.  There is no legal, administrative, or other
          -----------------------
proceeding, claim, or action of any nature seeking to impose, or that could
result in the imposition, on Wells Fargo or any Wells Fargo Subsidiary of any
liability relating to the release of hazardous substances as defined under any
local, state or federal environmental statute, regulation or ordinance
including, without limitation, CERCLA, pending or to the best of Wells Fargo's
knowledge, threatened against Wells Fargo or any Wells Fargo Subsidiary, the
result of which has had or could reasonably be expected to have a material
adverse effect upon Wells Fargo and its subsidiaries taken as a whole; to the
best of Wells Fargo's knowledge there is no reasonable basis for any such
proceeding, claim or action; and to the best of Wells Fargo's knowledge neither
Wells Fargo nor any Wells Fargo Subsidiary is subject to any agreement, order,
judgment, or decree by or with any court, governmental authority or third party
imposing any such environmental liability.

     (t)  Merger Co.  As of the Closing Date, Merger Co. will be a corporation
          ---------
duly organized, validly existing, duly qualified to do business and in good
standing under the laws of its jurisdiction of incorporation, and will have
corporate power and authority to own or lease its properties and assets and to
carry on its business. As of the Effective Date of the Merger, the execution,
delivery, and performance by Merger Co. of the Merger Agreement will have been
duly authorized by the Board of Directors and shareholders of Merger Co. and the
Merger Agreement will be a valid and binding obligation of Merger Co.
enforceable against Merger Co. in accordance with its terms.

     (g)  TBI will hold in confidence all documents and information concerning
Wells Fargo and its subsidiaries furnished to TBI and its representatives in
connection with the transactions contemplated by this Agreement and will not
release or disclose such information to any other person, except as required by
law and except to TBI's outside professional advisers in connection with this
Agreement, with the same undertaking from such professional advisers. If the
transactions contemplated by this Agreement shall not be consummated, such
confidence shall be maintained and such information shall not be used in
competition with Wells Fargo (except to the extent that such information can be
shown to be previously known to TBI, in the public domain, or later acquired by
TBI from other legitimate sources) and, upon request, all such documents, any
copies thereof and extracts therefrom shall immediately thereafter be returned
to Wells Fargo.

     (l)  At or before the Closing Date, TBI shall establish such additional
accruals and reserves as may be necessary to conform TBI's accounting and credit
loss reserve practices and methods to those of Wells Fargo and Wells Fargo's
plans with respect to the conduct of TBI's business following the Merger and to
provide for the costs and expenses relating to the consummation by TBI of the
Merger and the other transactions contemplated by this Agreement; provided,
however, that (i) TBI shall not be required to take such actions more than one
(1) day prior to the Closing Date, and (ii) based upon consultation with counsel
and accountants for TBI, no such adjustment shall (x) require any filing with
any governmental agency or regulatory authority, (y) violate any law, rule or
regulation applicable to TBI, or (z) otherwise materially disadvantage TBI if
the Merger were not consummated; provided, further, that TBI's compliance with
this paragraph 4(l) shall in no event constitute a breach of any other
representation, warranty or covenant contained in this Agreement.

     (m)  TBI shall obtain, at its sole expense, Phase I environmental
assessments for each owned bank facility and each non-residential OREO property.
Oral reports of such environmental assessments shall be delivered to Wells Fargo
no later than four (4) weeks and written reports shall be delivered to Wells
Fargo no later than eight (8) weeks from the date of this Agreement.  TBI shall
obtain, at its sole expense, Phase II environmental assessments for properties

OREO property)  and a written report of the results shall be delivered to Wells
Fargo within four weeks of execution of the definitive agreement.

Wells Fargo no later than four (4) weeks from the date of this Agreement.

     (o)  TBI will cooperate with Wells Fargo to assess the impact of the
transactions contemplated by this Agreement on TBI's continued compliance with
the FFIEC Requirements and TBI will take such action, in consultation with Wells
Fargo, as may be necessary to amend TBI's Year 2000 project assessment and
remediation plan.  TBI will continue its current preparations for compliance
with the FFIEC Requirements and will not rely on the consummation of the
transactions contemplated by this Agreement to satisfy its FFIEC requirements.

     (p)  TBI shall take such action as is necessary to terminate the Option
Plan effective as of the Effective Time.  TBI shall collect (and timely pay) all
applicable withholding and payroll taxes from each holder of an Option that is
exercised for shares of TBI Common Stock, and shall comply with all payroll
reporting requirements with respect thereto.

     (q)  Immediately prior to the Effective Time, TBI shall redeem and shall
cause TBI's Stock Option Plan Committee to take all action necessary to redeem
all Options which have not been exercised prior to the Closing Date ("Redeemed
Options") in an

                                     A-23
<PAGE>

amount for each Redeemed Option equal to the Fair Market Value Per Share of such
Redeemed Option minus the exercise price thereof as set forth in an Option
holder's Option Agreement or Option Agreements. TBI shall withhold (and timely
pay) all applicable withholding, and payroll taxes from the Cash Surrender
Amount, and shall comply with all payroll reporting requirements with respect to
such payments. In addition, TBI shall, and shall cause the TBI Stock Option Plan
Committee to, determine the "Fair Market Value" (as defined in the Option Plan)
of a Redeemed Option to be an amount equal to the Fair Market Value Per Share as
defined in this Agreement

     (r)  Subject to the terms and conditions contained herein, TBI shall
execute and deliver such additional instruments and documents and shall take
such further actions as may be necessary or appropriate to effectuate, carry
out, and comply with the terms of this Agreement and the transaction
contemplated heretofore.

     (s)  In anticipation of conditions reasonably expected to be imposed by the
Federal Reserve Board in approving the Merger ("Board Approval"), TBI agrees to
enter into and agrees to cause First National Bank of South Texas ("Bank") to
enter into such agreements prior to Closing for the divestiture ("Divestiture")
of the branch of Bank located in Pleasanton, Texas ("Branch") and to take such
other actions prior to the Closing as may be necessary (or may reasonably be
expected to be necessary) to be taken in connection therewith and in order to
satisfy any requirements related thereto to be imposed by the Federal Reserve
Board as a condition to the Board Approval. TBI shall use, and shall cause Bank
to use their respective commercially reasonable best efforts to cooperate with
Wells Fargo in identifying prospective bidders for the Branch, allowing
prospective bidders to conduct due diligence on the Branch, and in negotiating
the terms of the Divestiture; provided that neither TBI nor Bank shall enter
into definitive agreements for the Divestiture without the prior consent of
Wells Fargo, which consent shall not be unreasonably withheld; provided further
that the consummation of the Divestiture contemplated by this Paragraph 2(s)
will be subject to and contingent upon Closing of the Merger and will not occur
prior to the Effective Time of the Merger; provided further that the actions
taken to implement the Divestiture shall not impair or unduly burden or be
deemed to impair or unduly burden the operations of business of TBI and the TBI
Subsidiaries. Nothing contained in this Paragraph 4(s) shall diminish the
agreements, covenants, and obligations of the parties otherwise set forth in
Articles 4 and 5 of the Agreement.

however, that none of the provisions of this subparagraph shall apply to

TBI subsidiary for use in the Registration Statement or the Prospectus.

     (d)  Wells Fargo will file all documents required to be filed to list the

to effect said listings.

     (e)  The shares of Wells Fargo Common Stock to be issued by Wells Fargo to
the shareholders of TBI pursuant to this Agreement and the Merger Agreement
will, upon such issuance and delivery to said shareholders pursuant to the
Merger Agreement, be duly authorized, validly issued, fully paid and
nonassessable.  The shares of Wells Fargo Common Stock to be delivered to the
shareholders of TBI pursuant to the Merger Agreement are and will be free of any
preemptive rights of the stockholders of Wells Fargo.

<PAGE>

     (o)  With respect to the indemnification of directors and officers and with
respect to directors' and officers' insurance, Wells Fargo agrees as follows:

          (i)  Wells Fargo shall ensure that all rights to indemnification and
     all limitations of liability existing in favor of any person who is now, or
     has been at any time prior to the date hereof, or who becomes prior to the
     Effective Time of the Merger, a director or officer of TBI or any TBI
     Subsidiary (an "Indemnified Party" and, collectively, the "Indemnified
     Parties"), in TBI's Articles of Incorporation or Bylaws or similar
     governing documents of any TBI Subsidiary, as applicable in the particular
     case and as in effect on the date hereof, shall, with respect to claims
     arising from (A) facts or events that occurred before the Effective Time of
     the Merger, or (B) this Agreement or any of the transactions contemplated
     by this Agreement, whether in any case asserted or arising before or after
     the Effective Time of the Merger, survive the Merger and shall continue in
     full force and effect.  Nothing contained in this paragraph 5(o)(i) shall
     be deemed to preclude the liquidation, consolidation, or merger of TBI or
     any TBI Subsidiary, in which case all of such rights to indemnification and
     limitations on liability shall be deemed to survive and continue as
     contractual rights notwithstanding  any such liquidation or consolidation
     or merger; provided, however, that in the event of liquidation or sale of
                --------  -------
     substantially all of the assets of TBI, Wells Fargo shall guarantee, to the
     extent of the net asset value of TBI or any TBI Subsidiary as of the
     Effective Date of the Merger, the indemnification obligations of TBI or any
     TBI Subsidiary to the extent of indemnification obligations of TBI and the
     TBI Subsidiaries described above.  Notwithstanding  anything to the
     contrary contained in this paragraph 5(o)(i), nothing contained herein
     shall require Wells Fargo to indemnify any person who was a directors or
     officer of TBI or any TBI Subsidiary to a greater extent than TBI or any
     TBI Subsidiary is, as of the date of this Agreement, required to indemnify
     any such person.

          (ii)  any Indemnified Party wishing to claim indemnification under
     paragraph 5(o)(i), upon learning of any such claim, action, suit,
     proceeding, or investigation, shall promptly notify Wells Fargo thereof,
     but the failure to so notify shall not relieve Wells Fargo of any liability
     it may have to such Indemnified Party.  In the event of any such claim,
     action, suit, proceeding, or investigation (whether arising before of after
     the Effective Time of the Merger) (A) Wells Fargo shall have the right to
     assume the defense thereof and Wells Fargo shall not be liable to any
     Indemnified Party for any legal expenses of other counsel or any other
     expenses subsequently incurred by such Indemnified Party in connection with
     the defense thereof, except that if Wells Fargo elects not to assume such
     defense or counsel for the Indemnified Party advises that there are issues
     which raise conflicts of interest between Wells Fargo and the Indemnified
     Party, the Indemnified Party may retain counsel satisfactory to them, and
     Wells Fargo shall pay the reasonable fees and expenses of such counsel for
     the Indemnified Party promptly as statements therefor are received,
     provided, however, that Wells Fargo shall be obligated pursuant to this
     --------  -------
     subparagraph (ii) to

                                     A-27
<PAGE>

     pay for only one firm of counsel for all Indemnified Parties in any
     jurisdiction unless the use of one counsel for such Indemnified Parties
     would present such counsel with a conflict of interest, and (B) such
     Indemnified Party shall cooperate in the defense of any such matter.

     6.  Conditions Precedent to Obligation of TBI.  The obligation of TBI to
effect the Merger shall be subject to the satisfaction at or before the Time of
Filing of the following further conditions, which may be waived in writing by

affect the banking industry generally or changes in the general level of

                 [LETTERHEAD OF HOEFER & ARNETT, INCORPORATED]


[date of the proxy statement-prospectus]


Members of the Board of Directors
Texas Bancshares, Inc.
750 E. Mulberry
San Antonio, Texas  78212

Members of the Board:


You have requested our opinion as investment bankers as to the fairness, from a
financial point of view, to the shareholders of Texas Bancshares, Inc., San
Antonio, Texas ("TBI") of the terms of the proposed merger of a wholly-owned
subsidiary of Wells Fargo & Company, San Francisco, California ("Wells Fargo")
with and into TBI in accordance with the terms and conditions of the Amended and
Restated Agreement and Plan of Reorganization (the "Agreement"). Pursuant to the
Agreement and subject to the terms and conditions therein, each share of TBI
Common Stock outstanding immediately prior to the Effective Time of the Merger
(as defined in the Agreement), other than shares as to which statutory
dissenters' appraisal rights have been exercised, will be exchanged for the
number of shares of Wells Fargo Common Stock determined by dividing the Adjusted
Wells Fargo Shares (as defined below) by the number of shares of TBI Common
Stock then outstanding. The "Adjusted Wells Fargo Shares" shall be a number
equal to the Aggregate Share Amount divided by the Wells Fargo Measurement
Price. The "Wells Fargo Measurement Price" is defined as the average of the
closing prices of a share of Wells Fargo Common Stock as reported on the
consolidated tape of the New York Stock Exchange during the period of 10 trading
days ending on the day immediately preceding the meeting of shareholders
required by paragraph 4(c) of the Agreement. The "Aggregate Share Amount" shall
be $68,500,000 plus the aggregate exercise price of all Options exercised by
cash payments between the date hereof and the day immediately prior to the
Closing Date minus the Cash Surrender Amount. The "Cash Surrender Amount" shall
equal the difference between (i) the product of (A) the "Fair Market Value Per
Share" multiplied by (B) the number of Redeemed Options, minus (ii) the
aggregate exercise price of all Redeemed Options. "Fair Market Value Per Share"
shall mean $34.2988. "Option" has the meaning given it in paragraph 2(c) of the
Agreement.

As part of its investment banking business, Hoefer & Arnett, Incorporated is
continually engaged in the valuation of bank, bank holding company and thrift
securities in connection

                                       1
<PAGE>

with mergers and acquisitions nationwide. We have not previously provided
investment banking and financial advisory services to TBI.

In arriving at our opinion, we have reviewed and analyzed, among other things,
the following: (i) the Agreement; (ii) Annual Reports to Shareholders of TBI and
Wells Fargo for the years ended December 31, 1997 and December 31, 1998; (iii)
Quarterly Consolidated Financial Statements for Bank Holding Companies on Form
FR Y-9C as filed with the Federal Reserve for the quarters ended March 31, 1998,
June 30, 1998, September 30, 1998, December 31, 1998 and March 31, 1999; (iv)
certain other publicly available financial and other information concerning TBI
and Wells Fargo and the trading markets for the publicly traded securities of
TBI and Wells Fargo; and (v) publicly available information concerning other
banks and bank holding companies, the trading markets for their securities and
the nature and terms of certain other merger transactions we believe relevant to
our inquiry.  We have held discussions with senior management of TBI and Wells
Fargo concerning their past and current operations, financial condition and
prospects, as well as the results of regulatory examinations.

We have reviewed with senior management of TBI earnings projections for 1999
through 2003 for TBI as a stand-alone entity, assuming the merger does not
occur.  Such projections were prepared by TBI senior management.

In conducting our review and in arriving at our opinion, we have relied upon and
assumed the accuracy and completeness of the financial and other information
provided to us or publicly available, and we have not assumed any responsibility
for independent verification of the same.  We have relied upon the management of
TBI as to the reasonableness of the financial and operating forecasts and
projections (and the assumptions and bases therefor) provided to us, and we have
assumed that such forecasts and projections reflect the best currently available
estimates and judgments of TBI management.  We have also assumed, without
assuming any responsibility for the independent verification of the same, that
the aggregate allowances for loan losses for Wells Fargo and TBI are adequate to
cover such losses.  We have not made or obtained any evaluations or appraisals
of the property of TBI or Wells Fargo, nor have we examined any individual loan
credit files.  For purposes of this opinion, we have assumed that the merger
will have the tax, accounting and legal effects described in the Agreement and
assumed the accuracy of the disclosures set forth in the Agreement.  Our opinion
as expressed herein is limited to the fairness, from a financial point of view,
to the holders of shares of TBI Common Stock of the terms of the proposed

                                       2
<PAGE>

merger of a wholly-owned subsidiary of Wells Fargo with and into TBI and does
not address TBI's underlying business decision to proceed with the merger.

We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position and results of operations of TBI
and Wells Fargo, including interest income, interest expense, net interest
income, net interest margin, provision for loan losses, non-interest income,
non-interest expense, earnings, dividends, internal capital generation, book
value, intangible assets, return on assets, return on shareholders' equity,
capitalization, the amount and type of non-performing assets, loan losses and
the reserve for loan losses, all as set forth in the financial statements for
TBI and Wells Fargo; (ii) the assets and liabilities of TBI and Wells Fargo,
including the loan, investment and mortgage portfolios, deposits, other
liabilities, historical and current liability sources and costs and liquidity;
and (iii) the nature and terms of certain other merger transactions involving
banks and bank holding companies.  We have also taken into account our
assessment of general economic, market and financial conditions and our
experience in other transactions, as well as our experience in securities
valuation and our knowledge of the banking industry generally.  Our opinion is
necessarily based upon conditions as they exist and can be evaluated on the date
hereof and the information made available to us through the date hereof.

Based upon and subject to the foregoing, we are of the opinion as investment
bankers that, as of the date hereof, the terms of the proposed merger of a
wholly-owned subsidiary of Wells Fargo with and into TBI are fair, from a
financial point of view, to the holders of shares of TBI Common Stock.

It is understood that this letter is for the information of the Board of
Directors of TBI and does not constitute a recommendation to the Board of
Directors or to any shareholder of TBI with respect to any approval of the
merger.  We hereby consent to the reference to our firm in the proxy statement
or prospectus related to the merger transaction and to the inclusion of our
opinion as an exhibit to the proxy statement or prospectus related to the merger
transaction.

Very truly yours,

/s/ Hoefer & Arnett, Incorporated

           shareholder shall not have the right to dissent from any plan of
           merger in which there is a single surviving or new domestic or
           foreign corporation, or from any plan of exchange, if (1) the shares
           held by the shareholder are part of a class shares of which are

           immediately after the effective time of the merger or exchange, will
           be part of a class or series of shares of which are (i) listed, or
           authorized for listing upon official notice of issuance, on a
           national securities exchange, or (ii) held of record by not less than

Art. 5.12  Procedure for Dissent by Shareholders as to Said Corporate Actions

        A. Any shareholder of any domestic corporation who has the right to
           dissent from any of the corporate actions referred to in Article 5.11
           of this Act may exercise that right to dissent only by complying with
           the following procedures:

               (1) (a) With respect to proposed corporate action that is
           submitted to a vote of shareholders at a meeting, the shareholder
           shall file with the corporation, prior to the meeting, a written
           objection to the action, setting out that the shareholder's right to
           dissent will be exercised if the action is effective and giving the
           shareholder's address, to which notice thereof shall be delivered or
           mailed in that event. If the action is effected and the shareholder
           shall not have voted in favor of the action, the corporation, in the
           case of action other than a merger, or the surviving or new
           corporation (foreign or domestic) or other entity that is liable to
           discharge the shareholder's right of dissent, in the case of a
           merger, shall, within ten (10) days after the action is effected,
           deliver or mail to the shareholder written notice that the action has
           been effected, and the shareholder may, within ten (10) days from the
           delivery or mailing of the notice, make written demand on the
           existing, surviving, or new corporation (foreign or domestic) or
           other entity, as the case may be, for payment of the fair value of
           the shareholder's shares. The fair value of the shares shall be the
           value thereof as of the day immediately preceding the meeting,
           excluding any appreciation or depreciation in anticipation of the
           proposed action. The demand shall state the number and class of the
           shares owned by the shareholder and the fair value of the shares as
           estimated by the shareholder. Any shareholder failing to make demand
           within the ten (10) day period shall be bound by the action.

               (b)  With respect to proposed corporate action that is approved
           pursuant to Section A of Article 9.10 of this Act, the corporation,
           in the case of action other than a merger, and the surviving or new
           corporation (foreign or domestic) or other entity that is liable to
           discharge the shareholder's right of dissent, in the case of a
           merger, shall, within ten (10) days after the date the action is
           effected, mail to each shareholder of record as of the effective date
           of the action notice of the fact and date of the action and that the
           shareholder may exercise the shareholder's right to dissent from the
           action. The notice shall be accompanied by a copy of this Article and
           any articles or documents filed by the Corporation with the Secretary
           of State to effect the action. If the shareholder shall not have
           consented to the taking of the action, the shareholder may, within
           twenty (20) days after the mailing of the notice, make written demand
           on the existing, surviving, or new corporation (foreign or domestic)
           or other entity, as the case may be, for payment of the fair value of
           the

                                      C-2
<PAGE>

          shareholder's shares. The fair value of the shares shall be the value
          thereof as of the date the written consent authorizing the action was
          delivered to the corporation pursuant to Section A of Article 9.10 of
          this Act, excluding any appreciation or depreciation in anticipation
          of the action. The demand shall state the number and class of shares
          owned by the dissenting shareholder and the fair value of the shares
          as estimated by the shareholder. Any shareholder failing to make
          demand within the twenty (20) day period shall be bound by the action.

               (2) Within twenty (20) days after receipt by the existing,
          surviving, or new corporation (foreign or domestic) or other entity,
          as the case may be, of a demand for payment made by a dissenting
          shareholder in accordance with Subsection (1) of this Section, the
          corporation (foreign or domestic) or other entity shall deliver or
          mail to the shareholder a written notice that shall either set out
          that the corporation (foreign or domestic) or other entity accepts the
          amount claimed in the demand and agrees to pay that amount within
          ninety (90) days after the date on which the action was effected, and,
          in the case of shares represented by certificates, upon the surrender
          of the certificates duly endorsed, or shall contain an estimate by the
          corporation (foreign or domestic) or other entity of the fair value of
          the shares, together with an offer to pay the amount of that estimate
          within ninety (90) days after the date on which the action was
          effected, upon receipt of notice within sixty (60) days after that
          date from the shareholder that the shareholder agrees to accept that
          amount and, in the case of shares represented by certificates, upon
          the surrender of the certificates duly endorsed.

               (3)  If, within sixty (60) days after the date on which the
          corporate action was effected, the value of the shares is agreed upon
          between the shareholder and the existing, surviving, or new
          corporation (foreign or domestic) or other entity, as the case may be,
          payment for the shares shall be made within ninety (90) days after the
          date on which the action was effected and, in the case of shares
          represented by certificates, upon surrender of the certificates duly
          endorsed. Upon payment of the agreed value, the shareholder shall
          cease to have any interest in the shares or in the corporation.

     B.   If, within the period of sixty (60) days after the date on which the
          corporate action was effected, the shareholder and the existing,
          surviving, or new corporation (foreign or domestic) or other entity,
          as the case may be, do not so agree, then the shareholder or the
          corporate (foreign or domestic) or other entity may, within sixty (60)
          days after the expiration of the sixty (60) day period, file a
          petition in any court of competent jurisdiction in the county in which
          the principal office of the domestic corporation is located, asking
          for a finding and determination of the fair

                                      C-3
<PAGE>

          value of the shareholder's shares. Upon the filing of any such
          petition by the shareholder, service of a copy thereof shall be made
          upon the corporation (foreign or domestic) or other entity, which
          shall, within ten (10) days after service, file in the office of the
          clerk of the court in which the petition was filed a list containing
          the names and addresses of all shareholders of the domestic
          corporation who have demanded payment for their shares and with whom
          agreements as to the value of their shares have not been reached by
          the corporation (foreign or domestic) or other entity. If the petition
          shall be filed by the corporation (foreign or domestic) or other
          entity, the petition shall be accompanied by such a list. The clerk of
          the court shall give notice of the time and place fixed for the
          hearing of the petition by registered mail to the corporation (foreign
          or domestic) or other entity and to the shareholders named on the list
          at the addresses therein stated. The forms of the notices by mail
          shall be approved by the court. All shareholders thus notified and the
          corporation (foreign or domestic) or other entity shall thereafter be
          bound by the final judgment of the court.

     C.   After the hearing of the petition, the court shall determine the
          shareholders who have complied with the provisions of this Article and
          have become entitled to the valuation of and payment for their shares,
          and shall appoint one or more qualified appraisers to determine that
          value.  The appraisers shall have power to examine any of the books
          and records of the corporation the shares of which they are charged
          with the duty of valuing, and they shall make a determination of the
          fair value of the shares upon such investigation as to them may seem
          proper.  The appraisers shall also afford a reasonable opportunity to
          the parties interested to submit to them pertinent evidence as to the
          value of the shares.  The appraisers shall also have such power and
          authority as may be conferred on Masters in Chancery by the Rules of
          Civil Procedure or by the order of their appointment.

     D.   The appraisers shall determine the fair value of the shares of the
          shareholders adjudged by the court to be entitled to payment for their
          shares and shall file their report of that value in the office of the
          clerk of the court.  Notice of the filing of the report shall be given
          by the clerk to the parties in interest.  The report shall be subject
          to exceptions to be heard before the court both upon the law and the
          facts.  The court shall by its judgment determine the fair value of
          the shares of the shareholders entitled to payment for their shares
          and shall direct the payment of that value by the existing, surviving,
          or new corporation (foreign or domestic) or other entity, together
          with interest thereon, beginning 91 days after the date on which the
          applicable corporate action from which the shareholder elected to
          dissent was effected to the date of such judgment, to the shareholders
          entitled to payment.  The judgment shall be payable to the holders of
          uncertificated shares immediately but to the holders of shares
          represented

                                      C-4
<PAGE>

          by certificates only upon, and simultaneously with, the surrender to
          the existing, surviving, or new corporation (foreign or domestic) or
          other entity, as the case may be, of duly endorsed certificates for
          those shares. Upon payment of the judgment, the dissenting
          shareholders shall cease to have any interest in those shares or in
          the corporation. The court shall allow the appraisers a reasonable fee
          as court costs, and all court costs shall be allotted between the
          parties in the manner that the court determines to be fair and
          equitable.

     E.   Shares acquired by the existing, surviving, or new corporation
          (foreign or domestic) or other entity,  as the case may be, pursuant
          to the payment of the agreed value of the shares or pursuant to
          payment of the judgment entered for the value of the shares, as in
          this Article provided, shall, in the case of a merger, be treated as
          provided in the plan of merger and, in all other cases, may be held
          and disposed of by the corporation as in the case of other treasury
          shares.

     F.   The provisions of this Article shall not apply to a merger if, on the
          date of filing of the articles of merger, the surviving corporation is
          the owner of all the outstanding shares of the other corporations,
          domestic or foreign, that are parties to the merger.

     G.   In the absence of fraud in the transaction, the remedy provided by
          this Article to a shareholder objecting  to any corporate action
          referred to in Article 5.11 of this Act is the exclusive remedy for
          the recovery of the value of his shares or money damages to the
          shareholder with respect to the action.  If the existing, surviving,
          or new corporation (foreign or domestic) or other entity, as the case
          may be, complies with the requirements of this Article, any
          shareholder who fails to comply with the requirements of this Article
          shall not be entitled to bring suit for the recovery of the value of
          his shares or money damages to the shareholder with respect to the
          action.

Art. 5.13  Provisions Affecting Remedies of Dissenting Shareholders

        A.   Any shareholder who has demanded payment for his shares in
             accordance with either Article 5.12 or 5.16 of this Act shall not
             thereafter be entitled to vote or exercise any other rights of a
             shareholder except the right to receive payment for his shares
             pursuant to the provisions of those articles and the right to
             maintain an appropriate action to obtain relief on the ground that
             the corporate action would be or was fraudulent, and the respective
             shares for which payment has been demanded shall not thereafter be
             considered outstanding for the purposes of any subsequent vote of
             shareholders.

        B.   Upon receiving a demand for payment from any dissenting
             shareholder, the corporation shall make an appropriate notation
             thereof in its shareholder records. Within twenty (20) days after
             demanding payment for his shares in accordance with either Article
             5.12 or 5.16 of this Act, each holder of certificates representing
             shares so demanding payment shall submit such certificates to the
             corporation for notation thereon that such demand has been made.
             The failure of holders of certificated shares to do so shall, at
             the option of the corporation, terminate such shareholder's rights
             under Articles 5.12 and 5.16 of this Act unless a court of
             competent jurisdiction for good and sufficient cause shown shall
             otherwise direct. If uncertificated shares for which payment has
             been demanded or shares represented by a certificate on which
             notation has been so made shall be transferred, any new certificate
             issued therefor shall bear similar notation together with the name
             of the original dissenting holder of such shares and a transferee
             of such shares shall acquire by such transfer no rights in the
             corporation other than those which the original dissenting
             shareholder had after making demand for payment of the fair value
             thereof.

        C.   Any shareholder who has demanded payment for his shares in
             accordance with either Article 5.12 or 5.16 of this Act may
             withdraw such demand at any time before payment for his shares or
             before any petition has been filed pursuant to Article 5.12 or 5.16
             of this Act asking for a finding and determination of the fair
             value of such shares, but no such demand may be withdrawn after
             such payment has been made or, unless the corporation shall consent
             thereto, after any such petition has been filed. If, however, such
             demand shall be withdrawn as hereinbefore provided, or if pursuant
             to Section B of this Article the corporation shall terminate the
             shareholder's rights under Article 5.12 or 5.16 of this Act, as the
             case may be, or if no petition asking for a finding and
             determination of fair value of such shares by a court shall have
             been filed within the time provided in Article 5.12 or 5.16 of this
             Act, as the case may be, or if after the hearing of a petition
             filed pursuant to Article 5.12 or 5.16, the court shall determine
             that such shareholder is not entitled to the relief provided by

                                      C-6
<PAGE>

             those articles, then, in any such case, such shareholder and all
             persons claiming under him shall be conclusively presumed to have
             approved and ratified the corporate action from which he dissented
             and shall be bound thereby, the right of such shareholder to be
             paid the fair value of his shares shall cease, and his status as a
             shareholder shall be restored without prejudice to any corporate
             proceedings which may have been taken during the interim, and such
             shareholder shall be entitled to receive any dividends or other
             distributions made to shareholders in the interim.

     Section 145 of the Delaware General Corporation Law authorizes
indemnification of directors and officers of a Delaware corporation under
certain circumstances against expenses, judgments and the like in connection

     (a)   The undersigned registrant hereby undertakes:

     (1)   To file, during any period in which offers or sales are being made, a
posteffective 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) ((S)230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no more
than 20% change in the maximum offering price set forth in the "Calculation of

     (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.

Securities Act of 1933, each such posteffective amendment shall be deemed to be
a new registration statement relating to the

                                      II-1
<PAGE>

securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a posteffective 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 Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c)  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.

     (d)  The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) 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.

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

     (f)  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,

                                      II-2

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.

     (g)  The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

September 1, 1999



Board of Directors
Wells Fargo & Company
420 Montgomery Street
San Francisco, California 94163

Ladies and Gentlemen:

In connection with the proposed registration under the Securities Act of 1933,
as amended, of a maximum of 1,750,000 shares of common stock, par value $1-2/3
per share, of Wells Fargo & Company, a Delaware corporation (the "Company"), and
associated preferred stock purchase rights (such shares and rights collectively
referred to as the "Shares"), which are proposed to be issued by the Company in
connection with the merger (the "Merger") of a wholly-owned subsidiary of the
Company with Texas Bancshares, Inc., I have examined such corporate records and
other documents, including the registration statement on Form S-4 relating to
the Shares, and have reviewed such matters of law as I have deemed necessary for
this opinion, and I advise you that in my opinion:

     1.   The Company is a corporation duly organized and existing under the
          laws of the state of Delaware.

     2.   All necessary corporate action on the part of the Company has been
          taken to authorize the issuance of the Shares in connection with the
          Merger, and, when issued as described in the registration statement,
          the Shares will be legally and validly issued, fully paid and
          nonassessable.

I consent to the filing of this opinion as an exhibit to the registration
statement.

Sincerely,

/s/ Stanley S. Stroup
