  Dear Shareholder:

       A special meeting of shareholders of Texas Bancorporation, Inc.
  ("Bancorp") will be held on                                  , 1996 to
  consider and vote upon a proposal to approve the Agreement and Plan of
  Reorganization dated June 3, 1996 (the "Merger Agreement") between Bancorp and
  Norwest Corporation ("Norwest") pursuant to which a wholly-owned subsidiary of
  Norwest will merge with and into Bancorp (the "Merger").  If the Merger
  Agreement is approved and the Merger becomes effective, Bancorp will become a
  wholly-owned subsidiary of Norwest and holders of Bancorp common stock will be
  entitled to receive shares of Norwest common stock upon the terms and subject
  to the conditions set forth in the Merger Agreement.

       Bancorp's board of directors has unanimously approved the Merger
  Agreement as being advisable and in the best interests of Bancorp's
  shareholders and recommends that you vote for approval of the Merger
  Agreement.

       Enclosed with this letter are a notice of special meeting, which sets
  forth the time and location of the special meeting, and a Proxy Statement-
  Prospectus, which describes in more detail the terms and conditions of the
  Merger and discusses the background of and reasons for the Merger.  Please
  carefully review and consider the information in the Proxy Statement-
  Prospectus.  Additional information concerning Norwest, including its 1995
  annual report on Form 10-K, may be obtained from Norwest as indicated in the
  Proxy Statement-Prospectus under the section entitled "Incorporation of
  Certain Documents by Reference."

       Your vote is very important.  Please mark, date, sign and return the
  enclosed proxy in the enclosed postage prepaid envelope as soon as possible,
  regardless of whether you plan to attend the special meeting.  A failure to
  vote, either by not returning the enclosed proxy or by checking the "Abstain"
  box thereon, will have the same effect as a vote against approval of the
  Merger Agreement.  If you attend the meeting, you may vote in person if you
  wish, even though you have previously returned your proxy.

                             SHARES OF COMMON STOCK
                             ______________________

       This Proxy Statement-Prospectus is being provided to holders of the
common stock, par value $.01 per share ("Bancorp Common Stock") of Texas
Bancorporation, Inc., a Texas corporation ("Bancorp"), in connection with the
solicitation of proxies by the board of directors of Bancorp (the "Bancorp
Board") for a special meeting of Bancorp's shareholders to be held on
                     , 1996 (the "Special Meeting").

     At the Special Meeting, Bancorp's shareholders will consider and vote
upon a proposal to approve the Agreement and Plan of Reorganization dated June
3, 1996 (including all exhibits thereto, the "Merger Agreement") between Bancorp
and Norwest Corporation, a Delaware corporation ("Norwest"), pursuant to which a
wholly-owned subsidiary of Norwest will merge with and into Bancorp and Bancorp
will become a wholly-owned subsidiary of Norwest (the "Merger"). If the Merger
is approved and becomes effective, each share of Bancorp Common Stock
outstanding immediately prior to the Effective Time of the Merger (as
hereinafter defined) will be automatically converted into and exchanged for the
right to receive the fraction of a share of Norwest's common stock, par value
$1-2/3 per share ("Norwest Common Stock"), determined by dividing 762,500 by the
number of shares of Bancorp Common Stock outstanding immediately prior to the
Effective Time of the Merger (the "Exchange Ratio"). As of the date of this
Proxy Statement-Prospectus, there are 860,685 shares of Bancorp Common Stock
outstanding. Assuming there are 860,685 shares of Bancorp Common Stock

Ratio will equal 0.8859. For additional information concerning the consideration
to be received by holders of Bancorp Common Stock and certain risks due to
fluctuations in the price of Norwest Common Stock, see "THE MERGER--Merger
Consideration." A copy of the Merger Agreement is attached as Appendix A to this

       ) (the "Registration Statement") with the Securities and Exchange
Commission (the "Commission") registering under the Securities Act of 1933, as
amended (the "Securities Act"), the shares of Norwest Common Stock to be issued
in the Merger. In addition to serving as the proxy statement in connection with
the Special Meeting, this document constitutes the prospectus of Norwest filed
as part of the Registration Statement.

     Norwest Common Stock trades on the New York Stock Exchange ("NYSE") and
the Chicago Stock Exchange ("CHX") under the symbol "NOB." The closing price of
Norwest Common Stock as reported on the NYSE composite tape on           , 1996

PARTIES TO THE MERGER

     NORWEST. Norwest is a diversified financial services company which was
organized under the laws of Delaware in 1929 and is registered under the Bank
Holding Company Act of 1956, as amended (the "Bank Holding Company Act").
Norwest owns subsidiaries engaged in banking and in a variety of related
businesses. Norwest provides retail, commercial and corporate banking services
to its customers through banks located in Arizona, Colorado, Illinois, Indiana,
Iowa, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, Ohio,

banking, insurance agency services, computer and data processing services, trust
services, mortgage-backed securities servicing, and venture capital investment.

     At June 30, 1996, Norwest had consolidated total assets of $77.8 billion,
total deposits of $46.3 billion and total stockholders' equity of $5.6 billion.
Based on total assets at June 30, 1996, Norwest was the 12th largest commercial
banking organization in the United States.

     Norwest regularly explores opportunities for acquisitions of financial
institutions and related businesses. Norwest generally does not make a public
announcement of an acquisition until a definitive agreement has been signed.
Norwest generally provides information concerning the aggregate asset value of,
and the aggregate consideration anticipated to be paid for, its pending
acquisitions in its annual and quarterly reports filed with the Commission and
incorporated herein by reference. See "INCORPORATION OF CERTAIN DOCUMENTS BY
REFERENCE."

     Norwest's principal executive offices are located at Norwest Center, Sixth

documents incorporated by reference herein. See "AVAILABLE INFORMATION" and
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

     BANCORP. Bancorp, a bank holding company headquartered in Odessa, Texas,
derives substantially all of its revenues and income from the operation of its
wholly-owned bank subsidiary, Texas Bank ("Texas Bank" or the "Bank"), Odessa,
Texas. Texas Bank provides a full range of commercial and consumer banking
services to individuals and small and middle market businesses in the Permian
Basin as well as Central Texas. Texas Bank operates two full service branches in
Odessa, Texas, two in Austin, Texas, and one each in Pflugerville, Dripping
Springs, Burnet, Kingsland, and Buchanan Dam, Texas. As of June 30, 1996,
Bancorp had total consolidated assets of $167.0 million, total deposits of
$151.0 million and total shareholders' equity of $14.9 million. At June 30,
1996, Bancorp and Texas Bank employed 104 full time equivalent employees. See
"Information Concerning Bancorp."

SPECIAL MEETING AND VOTE REQUIRED

     SPECIAL MEETING. The Special Meeting will be held on         , 1996 at 
the offices of Bancorp located at 4101 North JBS Parkway, Odessa, Texas for the
purpose of voting on a




                                       7
<PAGE>
 
proposal to approve the Merger Agreement. Only holders of record of Bancorp
Common Stock at the close of business on         , 1996 (the "Record Date") will
be entitled to receive notice of and to vote at the Special Meeting. At the
Record Date, there were outstanding 860,685 shares of Bancorp Common Stock. For
additional information relating to the Special Meeting, see "MEETING
INFORMATION."

     VOTE REQUIRED. Approval of the Merger Agreement requires the affirmative
vote of the holders of at least two-thirds of the outstanding shares of Bancorp
Common Stock. Holders of Bancorp Common Stock are entitled to one vote per share
owned of record on the Record Date. If at least two-thirds of the votes eligible
to be cast by the holders of Bancorp Common Stock do not vote in favor of
approval of the Merger Agreement, Bancorp will continue to act as a separate
entity and a going concern. See "MEETING INFORMATION--Record Date; Voting
Rights; Vote Required."

The Merger

     EFFECT OF THE MERGER. If the Merger Agreement is approved and the Merger
becomes effective, a wholly-owned subsidiary of Norwest will merge with and into
Bancorp and Bancorp, as the surviving corporation in the Merger, will become a
wholly-owned subsidiary of Norwest. In the Merger, each share of Bancorp Common
Stock outstanding immediately prior to the Effective Time of the Merger will be
automatically converted into and exchanged for the right to receive the fraction
of a share of Norwest Common Stock determined in accordance with the Exchange
Ratio. See "THE MERGER--Merger Consideration."

     RECOMMENDATION OF BANCORP'S BOARD OF DIRECTORS. At a meeting of Bancorp's
board of directors (the "Bancorp Board") held on May 31, 1996, after considering
the terms and conditions of the Merger Agreement, the Bancorp Board unanimously
approved the Merger Agreement. The Bancorp Board believes that the Merger is
advisable and in the best interests of Bancorp and its shareholders and
recommends that shareholders of Bancorp vote in favor of approval of the Merger
Agreement. For a discussion of the circumstances surrounding the Merger and the
factors considered by the Bancorp Board in making its recommendation, see "THE
MERGER--Background of and Reasons for the Merger."

     CONDITIONS TO THE MERGER; TERMINATION OF THE MERGER AGREEMENT. The
obligations of Norwest and Bancorp to effect the Merger are subject to the
satisfaction or, if permissible under the Merger Agreement, waiver of a number
of conditions, in addition to approval of the Merger Agreement by Bancorp's
shareholders. The Merger Agreement is subject to termination by one or more
parties at any time prior to the Effective Time of the Merger upon the
occurrence of certain specified events. See "THE MERGER--Conditions to the
Merger" and "--Termination of the Merger Agreement."

     REGULATORY APPROVALS. The Merger is subject to the approval of the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board"). The
approval of the Federal Reserve Board was received on August 20, 1996. The
Merger is also subject to certain filing and other requirements of the Texas
Department of Banking. See "THE MERGER--Regulatory Approvals."

     EFFECTIVE TIME AND CLOSING OF THE MERGER. If the Merger Agreement is
approved at the Special Meeting and all other conditions to the Merger have been
satisfied or waived, the parties expect the Merger to become effective (the
"Effective Time of the Merger") upon the filing with the Texas Secretary of
State of articles of merger relating to the Merger (the "Articles of Merger") in
accordance with the relevant provisions of the TBCA. The parties expect to file
the Articles of Merger with the Texas Secretary of State as soon as practicable
following approval of the Merger Agreement at the Special Meeting. The closing
of the Merger (the "Closing") will be held on the date the Articles of Merger
are filed with the Texas Secretary of State or on such other date as the parties
may agree (the "Closing Date"). See "THE MERGER--Conditions to the Merger" and
"--Regulatory Approvals."


                                       8

     NO SOLICITATION. Bancorp and its subsidiaries, and their respective
directors, officers, representatives and agents, are prohibited under the Merger
Agreement from directly or indirectly soliciting, authorizing the solicitation
of or entering into any discussions with any party other than Norwest concerning
certain transactions involving the acquisition of Bancorp's capital stock or
assets. See "THE MERGER--No Solicitation."

     INTERESTS OF CERTAIN PERSONS IN THE MERGER. In the Merger, the directors
and executive officers will receive the same consideration for their shares of
Bancorp Common Stock as the other shareholders of Bancorp will receive for their
shares of Bancorp Common Stock. Certain members of the Bancorp Board and
management, however, may be deemed to have interests in the Merger that are in
addition to and separate from the interests of Bancorp's shareholders generally.
These interests include, among others, provisions in the Merger Agreement
relating to the continuation of certain director and officer indemnification
rights and the maintenance of certain directors' and officers' liability
insurance policies. See "THE MERGER--Interests of Certain Persons in the
Merger."

     DIRECTORS AND OFFICERS OF BANCORP AFTER THE MERGER. Following the Effective
Time of the Merger, Norwest will be the sole shareholder of Bancorp and, for
that reason, will be in a position to elect or appoint all of the directors and
officers of Bancorp.

     DISSENTERS' RIGHTS. Holders of Bancorp Common Stock will have the right to
dissent with respect to their shares of Bancorp Common Stock. For more
information concerning dissenters' rights and the procedures to be followed to
exercise such rights, see "THE MERGER--Dissenters' Rights."

     U.S. FEDERAL INCOME TAX CONSEQUENCES. The Merger is intended to be a tax-
free reorganization. Generally, no gain or loss will be recognized by Bancorp's
shareholders, except with respect to cash received for any remaining fractional
shares. The Merger's effectiveness is conditioned upon the receipt by Bancorp of
a written opinion of its counsel to that effect. See "THE MERGER--U.S. Federal
Income Tax Consequences."

     THE U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE MERGER MAY BE DIFFERENT
FOR PARTICULAR TYPES OF BANCORP SHAREHOLDERS OR IN LIGHT OF EACH BANCORP
SHAREHOLDER'S PERSONAL INVESTMENT CIRCUMSTANCES. FOR THAT REASON, BANCORP
SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S.
FEDERAL INCOME TAX CONSEQUENCES THAT MAY BE RELEVANT TO THEM IN CONNECTION WITH
THE MERGER, AS WELL AS THE APPLICATION TO THEM OF ANY STATE, LOCAL, FOREIGN, OR
OTHER TAX LAWS.

Market Information

Merger Agreement, and on        , 1996, the last practicable date prior to the
mailing of this Proxy Statement-Prospectus, the closing price per share of 
Norwest Common Stock (as reported on the NYSE composite tape) was $35.625 and 
$        , respectively. There is no public market for the Bancorp Common Stock.

     The market price for Norwest Common Stock will fluctuate between the date
of this Proxy Statement-Prospectus and the Effective Time of the Merger, which
will be a period of several weeks. The market value per share of the Norwest
Common Stock that Bancorp's shareholders ultimately receive in the Merger could
be more or less than its market value on the date of this Proxy Statement-
Prospectus. No assurance can be given concerning the market price of Norwest
Common Stock before or after the Effective Time of the Merger. Bancorp's
shareholders are advised to obtain current market quotations for Norwest Common
Stock.

  SELECTED CONSOLIDATED FINANCIAL DATA


       The following table sets forth certain selected historical consolidated
  financial information for Norwest and Bancorp.  The income statement and
  balance sheet data for Norwest and Bancorp included in the selected
  consolidated financial data for each of the five years in the period ended
  December 31, 1995 are derived from the respective audited consolidated
  financial statements of Norwest and Bancorp for such five-year period.  The
  selected financial data for the six-month periods ended June 30, 1996 and 1995
  are derived from the unaudited consolidated financial statements of Norwest
  and Bancorp for such periods.  All financial data derived from unaudited
  financial statements reflect, in the respective opinions of Norwest's and
  Bancorp's management, all adjustments (consisting of only normal recurring
  adjustments) necessary for a fair presentation of such data.  Results for the
  six-month period ended June 30, 1996 are not necessarily indicative of the
  results that may be expected for any other interim period or for the year as a
  whole.  The data in the following table should be read in conjunction with the
  consolidated financial statements of Norwest and Bancorp and the related notes
  thereto, included in this Proxy Statement-Prospectus in the case of Bancorp
  and incorporated herein by reference in the case of Norwest.  See

                              MEETING INFORMATION

  GENERAL


       This Proxy Statement-Prospectus is being furnished to holders of Bancorp
  Common Stock in connection with the solicitation of proxies by the Bancorp
  Board for use at the Special Meeting to be held on                   , 1996
  and at any adjournments or postponements thereof.  At the Special Meeting, 
  shareholders of Bancorp will consider and vote upon a proposal to approve the
  Merger Agreement. The Bancorp Board is not aware as of the date of this Proxy
  Statement-Prospectus of any business to be acted upon at the Special Meeting
  other than the proposal to approve the Merger Agreement. If other matters are
  properly brought before the Special Meeting or any adjournments or
  postponements thereof, the persons appointed as proxies will have discretion
  to vote or act on such matters according to their best judgment.

  RECORD DATE; VOTING RIGHTS; VOTE REQUIRED

       The Bancorp Board has fixed the close of business on             , 1996
  as the record date for the determination of shareholders of Bancorp entitled
  to receive notice of and to vote at the Special Meeting (the "Record Date").
  On the Record Date there were outstanding 860,685 shares of Bancorp Common
  Stock. Holders of Bancorp Common Stock are entitled to one vote per share held
  of record on the Record Date. The presence in person or by proxy at the
  Special Meeting of the holders of a majority of the shares of Bancorp Common
  Stock outstanding on the Record Date will constitute a quorum for the
  transaction of business at the Special Meeting.

       Under the TBCA and the Bancorp Articles and Bancorp Bylaws, approval of
  the Merger Agreement will require the affirmative vote of the holders of at
  least two-thirds of the shares of Bancorp Common Stock.  Directors and
  executive officers of Bancorp and their affiliates beneficially owned as of
  the Record Date an aggregate of 820,023, or approximately 95.3%, of the
  outstanding shares of Bancorp Common Stock.  Directors and executive officers
  of Bancorp intend to vote all shares of Bancorp Common Stock held in their
  individual capacities in favor of approval of the Merger Agreement.  If at
  least two-thirds of the votes eligible to be cast by the holders of Bancorp
  Common Stock do not vote in favor of approval of the Merger Agreement, Bancorp
  will continue to act as a separate entity and a going concern.  A failure to
  vote, either by not returning the enclosed proxy or by checking the "Abstain"
  box thereon, will have the same effect as a vote against approval of the
  Merger Agreement.

  VOTING AND REVOCATION OF PROXIES

       Shares of Bancorp Common Stock represented by a proxy properly signed and
  received at or prior to the Special Meeting, unless subsequently revoked, will
  be voted at the Special Meeting in accordance with the instructions thereon.
  If a proxy is signed and returned without indicating any voting instructions,
  shares of Bancorp Common Stock represented by such proxy will be voted FOR
  approval of the Merger Agreement.  Any proxy given pursuant to this
  solicitation may be revoked by the person giving it at any time before the
  proxy is voted by filing either an instrument revoking it or a duly executed
  proxy bearing a later date with the secretary of Bancorp prior to or at the
  Special Meeting or by voting the shares subject to the proxy in person at the
  Special Meeting.  Attendance at the Special Meeting will not by itself
  constitute a revocation of a proxy.

       A proxy may indicate that all or a portion of the shares represented
  thereby 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
  street name 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 

                                      15
<PAGE>
 
  considered as not present for such proposal, even though such 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 such proposal. The proposal to
  approve the Merger Agreement must be approved by the holders of at least two-
  thirds of the shares of Bancorp Common Stock outstanding on the Record Date.
  Because the proposal to approve the Merger Agreement requires the affirmative
  vote of a specified percentage of outstanding shares, the nonvoting of shares
  or abstentions with regard to this proposal will have the same effect as votes
  against the proposal.

  SOLICITATION OF PROXIES

       In addition to solicitation by mail, directors, officers and employees

                                  THE MERGER

       This section of the Proxy Statement-Prospectus describes certain aspects
  of the Merger.  The following description does not purport to be complete and
  is qualified in its entirety by reference to the Merger Agreement, a copy of
  which is attached as Appendix A to this Proxy Statement-Prospectus and
  incorporated herein by reference.  Shareholders are urged to read the Merger
  Agreement in its entirety.

       Parenthetical references are to sections of the Merger Agreement.

  GENERAL

       At the Effective Time of the Merger, a wholly-owned subsidiary of Norwest
  will be merged with and into Bancorp, with Bancorp being the surviving
  corporation in the Merger.  Following the Merger, Bancorp will be a wholly-
  owned subsidiary of Norwest.  Except with respect to remaining fractional
  shares and shares as to which dissenters' rights have been exercised, if the
  Merger is approved and becomes effective, each share of Bancorp Common Stock
  outstanding immediately prior to the Effective Time of the Merger will be
  automatically converted into and exchanged for the right to receive the
  fraction of a share of Norwest Common Stock determined in accordance with the
  Exchange Ratio.  Following the Effective Time of the Merger, Norwest will be
  the sole shareholder of Bancorp.  Shares of Norwest Common Stock issued and
  outstanding immediately before the Effective Time of the Merger will remain
  issued and outstanding immediately after the Effective Time of the Merger.

  BACKGROUND AND REASONS FOR THE MERGER

       A majority of the Bancorp Board instructed its management to identify
  opportunities for the sale of Bancorp because they believed that the current
  economic conditions were prime for garnering an optimum price for the Bancorp
  Common Stock.  They also believed that there was little potential for the
  market price of comparable banking organizations to maintain its lofty level.
  In evaluating potential candidates for the acquisition of Bancorp, the Bancorp
  Board determined that the best candidate would be a company whose stock is
  listed on one of the major exchanges to create liquidity for the shareholders,
  a company recognized as a high performing, well regarded, and highly rated
  financial institution nationwide.  In addition, the Bancorp Board determined
  that the transaction price must be adequate in terms of total consideration
  and that the transaction must be structured as a nontaxable stock for stock
  exchange so that each individual shareholder would have the opportunity to
  decide in the future whether he or she wished to continue with ownership of
  the company.

       The Bancorp Board believes the Merger will meet the criteria outlined
  above and, for that reason, recommends that Bancorp's shareholders approve 
  the Merger.

  MERGER CONSIDERATION

     SHARES OF NORWEST COMMON STOCK.  Except with respect to remaining
  fractional shares as described below and shares as to which dissenters' rights
  have been exercised, if the Merger Agreement is approved and the Merger
  becomes effective, each share of Bancorp Common Stock outstanding immediately
  prior to the Effective Time of the Merger will be automatically converted into
  and exchanged for the fraction of a share of Norwest Common Stock determined
  in accordance with the Exchange Ratio.  The term "Exchange Ratio," as used
  herein, means the fraction determined by dividing 762,500 by the number of
  shares of Bancorp Common Stock outstanding immediately prior to the Effective
  Time of the Merger. (Section 1(a))  As of the date of this Proxy Statement-
  Prospectus, there are 860,685 shares of Bancorp Common Stock outstanding.  The
  Merger Agreement prohibits Bancorp from redeeming or issuing shares of Bancorp
  Common Stock without the prior written consent of Norwest. (Section 4b)  See
  "--Conduct of Business Pending the Merger.  Assuming there are 860,685 shares
  of Bancorp 

                                      17
<PAGE>
 
  Common Stock outstanding immediately prior to the Effective Time of the
  Merger, the Exchange Ratio would equal 0.8859.

       THE PRICE OF NORWEST COMMON STOCK, AND THUS THE VALUE OF THE
  CONSIDERATION TO BE RECEIVED IN THE MERGER BY BANCORP'S SHAREHOLDERS, WILL
  FLUCTUATE BETWEEN THE DATE OF THIS PROXY STATEMENT-PROSPECTUS AND THE
  EFFECTIVE TIME OF THE MERGER. THERE CAN BE NO ASSURANCE THAT THE PRICE OF
  NORWEST COMMON STOCK AS OF THE EFFECTIVE TIME OF THE MERGER WILL NOT BE
  MATERIALLY LOWER THAN THE PRICE OF NORWEST COMMON STOCK AS OF THE DATE OF 
  THIS PROXY STATEMENT-PROSPECTUS OR AS OF THE DATE OF THE SPECIAL MEETING.

       CASH IN LIEU OF REMAINING FRACTIONAL SHARES.  In the event the aggregate
  number of shares of Norwest Common Stock to be received in the Merger by a
  Bancorp shareholder does not equal a whole number, the holder will receive
  cash in lieu of the remaining fractional share.  By way of illustration only,
  assuming an Exchange Ratio of .8859, a holder of 1,000 shares of Bancorp
  Common Stock would receive 885 shares of Norwest Common Stock and cash in lieu
  of the remaining 0.9 share of Norwest Common Stock.  The cash payment will be
  equal to the product of the fractional part of the share of Norwest Common
  Stock multiplied by the average of the closing prices of a share of Norwest
  Common Stock as reported on the NYSE's composite tape for the five trading
  days ending on the day immediately preceding the Special Meeting. (Section
  1(c))

  DISSENTERS' RIGHTS

       The following is a summary of the rights of dissenting shareholders
  pursuant to Texas law and does not purport to be a complete statement thereof.
  The summary is qualified in its entirety by reference to Articles 5.11 through
  5.13 of the TBCA, copies of which are set forth in full in Appendix C to this
  Proxy Statement-Prospectus.

       Record holders of Bancorp Common Stock will have the right under the TBCA
  to dissent with respect to the Merger and, subject to certain conditions,
  receive a cash payment equal to the fair value of their shares.  ANY
  SHAREHOLDER WHO WISHES TO ASSERT HIS OR HER DISSENTER'S RIGHTS MUST CAUSE
  BANCORP TO RECEIVE, BEFORE THE SPECIAL MEETING, A WRITTEN OBJECTION TO THE
  MERGER STATING THAT SUCH SHAREHOLDER'S RIGHT TO DISSENT WILL BE EXERCISED IF
  THE MERGER IS EFFECTIVE AND GIVING THE SHAREHOLDER'S ADDRESS TO WHICH ANY
  NOTICES SHOULD BE SENT, AND SUCH SHAREHOLDER MAY NOT VOTE ANY OF HIS OR HER
  SHARES IN FAVOR OF THE MERGER AGREEMENT.  VOTING AGAINST THE MERGER AGREEMENT
  IS NOT SUFFICIENT, IN AND OF ITSELF, FOR A SHAREHOLDER TO ASSERT HIS OR HER
  DISSENTER'S RIGHTS.

       In the event Bancorp's shareholders approve the Merger Agreement at the
  Special Meeting, Bancorp is required to deliver or mail a written notice to
  all shareholders who are entitled to demand payment for their shares no later
  than 10 days after the Effective Time of the Merger.  Any shareholder to whom
  a notice is sent by Bancorp and who desires to exercise his or her dissenter's
  rights must, within 10 days from the delivery or mailing of Bancorp's notice,
  make written demand on Bancorp for the payment of the fair value of his or her
  shares.  Pursuant to the TBCA, the fair value of the shares is the value
  thereof as of the day immediately preceding the Special Meeting, excluding any
  appreciation or depreciation in anticipation of the Merger.  The demand must
  state the number of shares owned by the shareholder and the fair value of the
  shares as estimated by the shareholder.  Any shareholder who does not demand
  payment for his or her shares within the 10 day period is bound by the Merger.
  Upon receiving a demand for payment from a dissenting shareholder, Bancorp
  must make an appropriate notation of the demand in its shareholder records.
  Within 20 days after making such demand, the dissenting shareholder must
  submit his or her share certificates to Bancorp for notation thereon that
  demand has been made.

       Within 20 days after Bancorp's receipt of a demand from a dissenting
  shareholder, it must deliver or mail to the shareholder a written notice that
  either accepts the amount claimed in the shareholder's demand as the fair
  value of the shares or sets forth Bancorp's estimate of the fair value of the
  shares.  If the shareholder's amount is accepted, the notice must state that

                                      18
<PAGE>
 
  Bancorp will pay that amount to the shareholder within 90 days after the 
  date the Merger was effected, upon surrender of the certificates for the
  shareholder's shares, duly endorsed.  If the notice includes Bancorp's
  estimate of the fair value of the shares, such notice must also include an
  offer to pay the amount of that estimate to the shareholder within 90 days
  after the date the Merger was effected, upon receipt of notice within 60 days
  after that date from the shareholder that he or she agrees to accept that
  amount and surrenders the certificates for the shareholder's shares.  The
  failure of a dissenting shareholder to submit his or her share certificates
  for notation terminates such shareholder's right to dissent, at the option of
  Bancorp, unless a court of competent jurisdiction for good and sufficient
  cause otherwise directs.

       If, within 60 days after the date on which the Merger was effected, the
  value of the shares is agreed upon by Bancorp and the dissenting shareholder,
  then payment for the shares must be made by Bancorp to the shareholder within
  90 days after the date on which the Merger was effected, upon the
  shareholder's surrender of the certificates, duly endorsed. Upon payment of
  the agreed value, the shareholder ceases to have any interest in the shares 
  or Bancorp.

       If, however, within 60 days after the date on which the Merger was
  effected, the dissenting shareholder and Bancorp do not agree upon the value
  of the shares, then either may, within an additional 60 days after the
  expiration of the first 60 day period, file a petition in any court of
  competent jurisdiction in Ector County, Texas, asking the court to determine
  the fair value of the shareholder's shares.  If the petition is filed by the
  shareholder, Bancorp must, within 10 days after service of the petition upon
  it, file in the office of the clerk of the court a list containing the names
  and addresses of all shareholders who have demanded payment for their shares
  and with whom agreements as to the value of their shares have not been reached
  by Bancorp.  If the petition is filed by Bancorp, then the petition must be
  accompanied by such list.  The clerk of the court then gives notice of the
  time and place fixed for the hearing by the court of the petition by
  registered mail to Bancorp and each of the shareholders named on the list at
  the addresses stated therein, and the shareholders as notified and Bancorp are
  bound by the final judgment of the court.

       After the hearing of the petition, the court determines the shareholders
  who have complied with the foregoing procedure and become entitled to the
  valuation of and payment for their shares and appoints one or more appraisers
  to determine that value.  The appraisers may examine the books and records of
  Bancorp and are required to afford a reasonable opportunity to the interested
  parties to submit pertinent evidence as to the value of the shares. The
  appraisers then determine the fair value of the shares of all of the
  shareholders entitled to payment for their shares and file their report of
  that value in the office of the clerk of the court, who gives notice of such
  filing to the parties in interest.  After hearing any exceptions to the
  report, the court then determines the fair value of the shares of all the
  shareholders entitled to payment and directs Bancorp to pay that value,
  together with interest thereon, beginning 91 days after the date on which the
  Merger was effected until the date of the judgment, to the shareholders
  entitled to payment, upon surrender of the certificates for their shares, duly
  endorsed.  Upon payment of the judgment, the dissenting shareholders cease to
  have any interest in those shares or Bancorp.  The court allows the appraisers
  a reasonable fee as court costs, and all court costs are allotted between the
  parties in a manner as the court determines to be fair and equitable.

       Any shareholder who has demanded payment for his or her shares may
  withdraw such demand at any time before payment for the shares or before any
  petition is filed seeking a determination of the fair value of the shares and,
  with the consent of Bancorp, after any such petition is filed.  If (i) the
  demand is withdrawn, (ii) Bancorp has terminated the shareholder's rights
  under Article 5.12 because of the failure of the shareholder to submit the
  certificates for his or her shares for notation of demand, (iii) no petition
  is timely filed, or (iv) after hearing the petition, the court determines the
  shareholder is not entitled to the relief provided by Article 5.12, then the
  shareholder is conclusively presumed to have approved the Merger and is bound
  thereby, and his or her status as a shareholder is restored and he or she is
  entitled to receive any dividends paid to shareholders in the interim.

                                      19
<PAGE>
 
       In the absence of fraud, the remedy provided by Article 5.12 of the TBCA
  to a shareholder objecting to the proposed Merger is the exclusive remedy for
  the recovery of the value of his or her shares and, if Bancorp complies with
  Article 5.12, then any shareholder who fails to comply with the requirements
  of Article 5.12 is not entitled to bring suit for the recovery of the value of
  his or her shares or money damages to the shareholder with respect to the
  Merger.

  SURRENDER OF CERTIFICATES

       Promptly following the Effective Time of the Merger, Norwest Bank
  Minnesota, National Association, acting in the capacity of exchange agent for
  Norwest (the "Exchange Agent"), will mail to each holder of record of shares
  of Bancorp Common Stock a form of letter of transmittal, together with
  instructions for the exchange of such holder's stock certificates for a
  certificate representing Norwest Common Stock.

       SHAREHOLDERS OF BANCORP SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY
  RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.

       Upon surrender to the Exchange Agent of one or more certificates for
  Bancorp Common Stock together with a properly completed letter of transmittal,
  there will be issued and mailed to the holder a certificate representing the
  number of whole shares of Norwest Common Stock to which such holder is
  entitled and, if applicable, a check for the amount representing any remaining
  fractional share (without interest).  A certificate for Norwest Common Stock
  may be issued in a name other than the name in which the surrendered
  certificate is registered only if (i) the certificate surrendered is properly
  endorsed and is otherwise in proper form for transfer and (ii) the person
  requesting the issuance of such certificate either pays to the Exchange Agent
  any transfer or other taxes required by reason of the issuance of a
  certificate for such shares in a name other than the registered holder of the
  certificate surrendered or establishes to the satisfaction of the Exchange
  Agent that such taxes have been paid or are not due.

       All Norwest Common Stock issued pursuant to the Merger will be deemed
  issued as of the Effective Time of the Merger.  No dividends in respect of the
  Norwest Common Stock with a record date after the Effective Time of the Merger
  will be paid to the former shareholders of Bancorp entitled to receive
  certificates for shares of Norwest Common Stock until such shareholders
  surrender their certificates representing shares of Bancorp Common Stock.
  Upon such surrender, there shall be paid to the stockholder in whose name the
  certificates representing such shares of Norwest Common Stock are issued any
  dividends the record and payment dates of which shall have been after the
  Effective Time of the Merger and before the date of such surrender.  After
  such surrender, there shall be paid to the person in whose name the
  certificate representing such shares of Norwest Common Stock is issued, on the
  appropriate dividend payment date, any dividend on such shares of Norwest
  Common Stock which shall have a record date after the Effective Time of the
  Merger, as the case may be, and prior to the date of surrender, but a payment
  date subsequent to the surrender.  In no event shall the persons entitled to
  receive such dividends be entitled to receive interest on amounts payable as
  dividends.

  CONDITIONS TO THE MERGER

       CONDITIONS TO THE OBLIGATIONS OF NORWEST AND BANCORP.  The obligations of
  both Norwest and Bancorp to effect the Merger are subject to the satisfaction
  as of the Effective Time of the Merger or, if permissible under the Merger
  Agreement, waiver of a number of conditions, including, among others, the
  following:  (i) the approval of the Merger Agreement by the requisite vote of
  Bancorp's shareholders; (ii) the receipt of all requisite regulatory
  approvals; (iii) the absence of any order issued by any court or governmental
  authority of competent jurisdiction restraining, enjoining or otherwise
  prohibiting consummation of the Merger; and (iv) the effectiveness of the
  Registration Statement. (Sections 6 and 7)

                                      20

       CONDITIONS TO THE OBLIGATION OF BANCORP.  The obligation of Bancorp to
  effect the Merger is subject to the satisfaction as of the Effective Time of
  the Merger or, if permissible under the Merger Agreement, waiver of certain
  additional conditions, including, among others, the following:  (i) the
  performance by Norwest in all material respects of the agreements made by
  Norwest in the Merger Agreement and the truthfulness in all material respects
  of the representations made by Norwest in the Merger Agreement; (ii) the
  approval for listing on the NYSE and CHX of the shares of Norwest Common Stock
  to be issued in the Merger; and (iii) the receipt of an opinion of counsel to
  Bancorp at the Closing regarding certain federal income tax consequences of
  the Merger. (Section 6) See "-- U.S. Federal Income Tax Consequences."

       CONDITIONS TO THE OBLIGATION OF NORWEST.  The obligation of Norwest to
  effect the Merger is subject to the satisfaction as of the Effective Time of
  the Merger or, if permissible under the Merger Agreement, waiver of certain
  additional conditions, including, among others, the following (i) the
  performance by Bancorp in all material respects of the agreements made by
  Bancorp in the Merger Agreement and the truthfulness in all material respects
  of the representations made by Bancorp in the Merger Agreement; (ii) the
  absence of any condition or requirement in any approval, license or consent
  relating to the Merger that, in the good faith judgment of Norwest, is
  unreasonably burdensome to Norwest; and (iii) at any time since June 3, 1996
  (the date of the Merger Agreement) the total number of shares of Bancorp
  Common Stock outstanding and subject to issuance upon exercise (assuming for
  this purpose that phantom shares and other share equivalents constitute
  Bancorp Common Stock) of all warrants, options, conversion rights (including
  equity securities convertible into Bancorp Common Stock), phantom shares or
  other share equivalents shall not have exceeded 860,685.  Under the terms of
  the Merger Agreement, the receipt by Norwest of an opinion of Bancorp's
  independent auditors that the activities of Bancorp will not preclude the
  Merger from being treated as a pooling of interests is also a condition to
  Norwest's obligation to effect the Merger; however, Norwest intends to account
  for the Merger as a purchase and therefore anticipates waiving this condition.
  (Section 7)  See "--Certain Additional Agreements."

       See Sections 6 and 7 of the Merger Agreement for additional conditions to
  the Merger becoming effective.

  REGULATORY APPROVALS

       The Merger is subject to prior approval by the Federal Reserve Board
  under the Bank Holding Company Act. The approval of the Federal Reserve Board
  was received on August 20, 1996. The Merger is also subject to certain filing
  and other requirements of the Texas Department of Banking.

       The approval of any application merely implies satisfaction of regulatory
  criteria for approval, which do not include review of the Merger from the
  standpoint of the adequacy of the consideration to be received by, or fairness
  to, shareholders.  Regulatory approvals do not constitute an endorsement or
  recommendation of the proposed Merger.

       Norwest and Bancorp 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.  The parties currently
  intend to seek to obtain 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 receipt of all necessary regulatory approvals is a condition to
  effecting the Merger.  See "--Conditions to the Merger" and "--Termination of
  the Merger Agreement."

  TERMINATION OF THE MERGER AGREEMENT

       The Merger Agreement may be terminated at any time prior to the Effective
  Time of the Merger (i) by mutual written consent of the parties; (ii) by
  either party by written notice to the other if the Merger has not become
  effective by December 31, 1996, unless such failure of the Merger to become
  effective is due to the failure of the party seeking termination to perform or
  observe in all material respects the covenants and agreements to be performed
  or observed by it under the Merger Agreement; (iii) by either party by written
  notice to the other if any court or governmental authority of competent
  jurisdiction has issued a final order restraining, enjoining or otherwise

  Bancorp within five business days after the end of the Index Measurement
  Period (as defined below) if both (A) the Norwest Measurement Price (as
  defined below) is less than $30 and (B) the number obtained by dividing the
  Norwest Measurement Price by 35.625 (the closing price of Norwest Common Stock
  on the trading day immediately preceding the date of the Merger Agreement) is
  less than the number obtained by dividing the Final Index Price (as defined
  below) by the Initial Index Price (as defined below) and subtracting 0.15 from
  such quotient.  (Section 9)

       For purposes of clause (iv) above:

               (i)    The "Company Market Capitalization" shall mean (a) the
       price of one share of the common stock of a given company at the close of
       the trading day immediately preceding the date of the Merger Agreement
       multiplied by (b) the number of shares of common stock of such company
       outstanding as of March 31, 1996 (adjusted for any stock dividend,
       reclassification, recapitalization, exchange of shares or similar
       transaction between March 31, 1996 and the close of the trading day
       immediately preceding the date of the Merger Agreement).

               (ii)   The "Final Index Price" shall mean the sum of the
       following, calculated for each of the companies in the Index Group: (a)
       the Final Price for each such company multiplied by (b) the Weighting
       Factor (as defined below) for each such company.

               (iii)  The "Final Price" of any company in the Index Group shall
       mean the average of the daily closing prices of a share of common stock
       of such company, as reported on the consolidated transaction reporting
       system for the market or exchange on which such common stock is
       principally traded, during the Index Measurement Period.

               (iv)   The "Index Group" shall mean all of those companies listed
       below the common stock of which is publicly traded and as to which there
       is, during the period of 20 

                                      23

  definitions above so as to be comparable to what the price would have been if
  the record date of the Common Stock adjustment had been immediately following
  the Effective Time of the Merger.

  AMENDMENT OF MERGER AGREEMENT

       The Merger Agreement may be amended by the parties thereto, pursuant to
  action taken by their respective boards of directors or pursuant to authority
  delegated by their respective boards of directors, at any time before or after
  approval of the Merger Agreement by Bancorp's shareholders, provided that,
  after the Merger Agreement is approved by Bancorp's shareholders, no amendment
  can be made to the Merger Agreement that changes in a manner materially
  adverse to Bancorp's shareholders the consideration to be received by
  Bancorp's shareholders in the Merger.  (Section 17)

  WAIVER OF PERFORMANCE OF OBLIGATIONS

       Any of the parties to the Merger Agreement may, by a signed writing, give
  any consent, take any action with respect to the termination of the Merger
  Agreement or otherwise, or waive any of the 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.  (Section 16)

                                      24
<PAGE>
 
  EFFECT ON EMPLOYEE BENEFIT PLANS

       The Merger Agreement provides that, subject to any eligibility
  requirements applicable to such plans, employees of Bancorp shall be entitled
  to participate in those Norwest employee benefit and welfare plans specified
  in the Merger Agreement.  The eligible employees of Bancorp shall enter each
  of such plans no later than the first day of the calendar quarter which begins
  at least 32 days after the Effective Time of the Merger.  Bancorp's employees
  will generally continue to participate in welfare and retirement plans
  maintained by Bancorp until entering Norwest's plans.  Eligible Bancorp
  employees will receive credit for past service for the purpose of determining
  certain benefits under certain but not all of Norwest's benefit plans.
  (Section 8)

  INTERESTS OF CERTAIN PERSONS IN THE MERGER

       Certain members of Bancorp's management and the Bancorp Board may be
  deemed to have interests in the Merger in addition to their interests as
  shareholders of Bancorp generally.  The Bancorp Board was aware of these
  interests and considered them, among other matters, in unanimously approving
  the Merger Agreement and the transactions contemplated thereby.

       INDEMNIFICATION, INSURANCE.  In the Merger Agreement, Norwest has agreed
  that all rights to indemnification and all limitations of liability in the
  Bancorp Articles or Bancorp Bylaws, existing in favor of any person who is,
  has been or becomes prior to the Effective Time of the Merger, a director or
  officer of Bancorp or the Bank, shall survive the Merger and continue in full
  force and effect.  These rights to indemnification and limitations of
  liability are to survive with respect to all claims arising from (i) facts or
  events that occurred before the Effective Time of the Merger, or (ii) the
  Merger Agreement or the transaction contemplated thereby.

       Norwest has also agreed, for a period of three years after the Effective
  Time of the Merger, to use its best efforts to cause to be maintained in
  effect the current policies of directors' and officers' liability insurance
  maintained by Bancorp (provided that Norwest may substitute therefor policies
  of at least the same coverage and amounts, containing terms and conditions
  which are substantially no less advantageous) with respect to claims arising
  from facts or events which occurred before the Effective Time of the Merger.
  However, Norwest is not obligated to expend, in order to maintain such
  insurance coverage, an amount per year in excess of 125% of the amount of the
  annual premiums paid as of the date hereof by Bancorp (the "Maximum Amount").
  If the amount of the annual premiums necessary to maintain or procure such
  insurance coverage exceeds the Maximum Amount, Norwest is obligated to use
  reasonable efforts to obtain as much comparable insurance as can be obtained
  for the Maximum Amount.

  U.S. FEDERAL INCOME TAX CONSEQUENCES

       The following is a discussion of the material federal income tax
  consequences of the Merger that are generally applicable to Bancorp's
  shareholders.  The discussion is based on currently existing provisions of the
  Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
  promulgated and proposed thereunder, published Internal Revenue Service
  rulings and pronouncements and court decisions as in effect on the date
  hereof.  All of the above authorities are subject to change (possibly
  retroactive) by legislative, administrative or judicial action.  Any such
  change could alter the tax consequences described herein.  The following
  discussion is intended only as a summary of certain principal federal income
  tax consequences of the Merger and does not purport to be a complete analysis
  or listing of all of the potential tax effects relevant to a decision on
  whether to vote in favor of approval of the Merger Agreement.

       The parties expect the Merger to qualify as a reorganization under
  Section 368(a) of the Code.  Except for cash received in lieu of remaining
  fractional share interest in Norwest Common Stock, holders of shares of
  Bancorp Common Stock will recognize no gain or loss on 

                                      25
<PAGE>
 
  the receipt of Norwest Common Stock in exchange therefor. The Merger's
  effectiveness is conditioned upon the receipt by Bancorp of a written opinion
  of Thompson & Knight, a Professional Corporation, counsel to Bancorp,
  substantially to the effect that, for U.S. federal income tax purposes: (i)
  the Merger will constitute a reorganization within the meaning of Sections
  368(a)(1)(A) and 368(a)(2)(E) of the Code; (ii) no gain or loss will be
  recognized by the holders of Bancorp Common Stock upon receipt of Norwest
  Common Stock except for cash received in lieu of fractional shares; and (iii)
  the basis of the Norwest Common Stock received by the shareholders of Bancorp
  will be the same as the basis of the Bancorp Common Stock exchanged therefor,
  decreased by the tax basis allocated to any fractional share interest
  exchanged for cash; and (iv) the holding period of the shares of Norwest
  Common Stock received by the shareholders of Bancorp will include the holding
  period of the Bancorp Common Stock exchanged therefor, provided such shares
  were held as a capital asset as of the Effective Time of the Merger.

       The form of the opinion of counsel, the original of which will be
  delivered on the Closing Date, is filed as an exhibit to the Registration
  Statement. The foregoing discussion is only a summary of the tax consequences
  as described in the opinion.  An opinion of counsel only represents counsel's
  best legal judgment and has no binding effect or official status of any kind,
  and no assurance can be given that contrary positions may not be taken by the
  Internal Revenue Service (the "IRS") or a court considering the issues.
  Neither Bancorp nor Norwest has requested or will request a ruling from the
  IRS with regard to the federal income tax consequences of the Merger.

       The foregoing tax consequences may not be applicable to Bancorp
  shareholders subject to special treatment under certain federal income tax
  laws, such as dealers in securities, banks, insurance companies, tax-exempt
  entities, non-United States persons, and stockholders who acquired Bancorp
  stock pursuant to the exercise of Bancorp options or otherwise as
  compensation.

       THE FOREGOING IS A GENERAL SUMMARY OF THE MATERIAL U.S. FEDERAL INCOME
  TAX CONSEQUENCES OF THE MERGER TO BANCORP SHAREHOLDERS, WITHOUT REGARD TO THE
  PARTICULAR FACTS AND CIRCUMSTANCES OF EACH SHAREHOLDER'S TAX SITUATION AND
  STATUS.  EACH BANCORP SHAREHOLDER SHOULD CONSULT HIS OR HER OWN TAX ADVISOR
  REGARDING ANY SUCH SPECIFIC TAX SITUATION AND STATUS, INCLUDING THE
  APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND FOREIGN LAWS AND THE
  POSSIBLE EFFECT OF CHANGES IN FEDERAL AND OTHER TAX LAWS.

  RESALE OF NORWEST COMMON STOCK

       The shares of Norwest Common Stock issuable to shareholders of Bancorp
  upon the Merger becoming effective have been registered under the Securities
  Act.  Such shares may be traded freely and without restriction by those
  shareholders not deemed to be "affiliates" of Bancorp or Norwest as that term
  is defined in the rules under the Securities Act.  Norwest Common Stock
  received by those shareholders of Bancorp who are deemed to be "affiliates" of
  Bancorp may be resold without registration as provided for by Rule 145 or as
  otherwise permitted under the Securities Act.  Persons who may be deemed to be
  affiliates of Bancorp generally include individuals or entities that control,
  are controlled by or are under common control with, Bancorp and may include
  the executive officers and directors of Bancorp as well as certain principal
  shareholders of Bancorp.  In the Merger Agreement, Bancorp has agreed to use
  its best efforts to cause each shareholder who may reasonably be deemed to be
  an affiliate of Bancorp to enter into an agreement with Norwest concerning the
  sale, transfer or other disposition of the shares of Norwest Common Stock to
  be received by such person in the Merger. (Section 4(l))  This Proxy
  Statement-Prospectus does not cover any resales of Norwest Common Stock
  received by affiliates of Bancorp.

  STOCK EXCHANGE LISTING

                                      26
<PAGE>
 
       The Merger Agreement provides for the filing by Norwest of listing
  applications with the NYSE and the CHX covering the shares of Norwest Common
  Stock issuable upon the Merger becoming effective.  Consummation of the Merger
  is conditioned on the authorization for listing of such shares on the NYSE and
  CHX.  (Section 6)

  ACCOUNTING TREATMENT

       Norwest intends to account for the Merger as a purchase under generally
  accepted accounting principles.

  EXPENSES

       Except as otherwise provided in the Merger Agreement, Norwest and Bancorp
  will each pay their own expenses in connection with the Merger, including fees
  and expenses of their respective independent auditors and counsel.


                      COMPARISON OF RIGHTS OF HOLDERS OF
                 BANCORP COMMON STOCK AND NORWEST COMMON STOCK

  GENERAL

       Bancorp is incorporated under the laws of the state of Texas.  Norwest is
  incorporated under the laws of the state of Delaware.  The rights of Bancorp's
  shareholders are currently governed by the TBCA and the Bancorp Articles and
  Bancorp Bylaws.  If Bancorp's shareholders approve the Merger Agreement and
  the Merger becomes effective, shareholders of Bancorp will become stockholders
  of Norwest.  For that reason, after the Effective Time of the Merger, their
  rights will be governed by the DGCL and the Norwest Certificate and Norwest
  Bylaws.

       The following is a comparison of certain rights of holders of Bancorp
  Common Stock with the rights of holders of Norwest Common Stock. It is not
  intended to be complete and is qualified in its entirety by reference to the
  relevant provisions of the laws and documents discussed below.  Additional
  information concerning the rights of holders of Norwest Common Stock is
  provided in Norwest's current report on Form 8-K dated April 30, 1996 filed
  with the Commission and incorporated herein by reference.  See "INCORPORATION
  OF CERTAIN DOCUMENTS BY REFERENCE."

  DIRECTORS

       BANCORP. The Bancorp Bylaws provide that the Bancorp Board shall consist
  of six directors.

       NORWEST.  The Norwest Bylaws provide for a board of directors consisting
  of not less than 10 nor more than 23 persons, each serving for a term of one
  year or until his or her earlier death, resignation or removal.  The number of
  directors of Norwest is currently fixed at 14.  Directors of Norwest may be
  removed with or without cause by the affirmative vote of the holders of a
  majority of the shares of Norwest capital stock entitled to vote thereon.
  Vacancies on the Norwest Board may be filled by a majority of the remaining
  directors or, in the event a vacancy is not so filled or if no director
  remains, by the stockholders.  Directors of Norwest are elected by plurality
  of the votes of shares of Norwest capital stock entitled to vote thereon
  present in person or by proxy at the meeting at which directors are elected.
  The Norwest Certificate does not currently permit cumulative voting in the
  election of directors.  See "NORWEST CAPITAL STOCK AND RIGHTS--Common Stock."

                                      27
<PAGE>
 
  AMENDMENT OF ARTICLES OR CERTIFICATE OF INCORPORATION AND BYLAWS

       BANCORP.  Under the TBCA, certain amendments to the 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.  The Bancorp Bylaws provide that
  the Bylaws may be amended by a majority of the Bancorp Board.

       NORWEST.  The Norwest Certificate may be amended only if the proposed
  amendment is approved by the Norwest Board 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.
  The Norwest Bylaws may be amended by a majority of the Norwest Board or by a
  majority of the outstanding stock entitled to vote thereon.  Shares of Norwest
  Preferred Stock and Norwest Preference Stock currently authorized in the
  Norwest Certificate may be issued by the Norwest Board without amending the
  Norwest Certificate or otherwise obtaining the approval of Norwest's
  stockholders.  See "NORWEST CAPITAL STOCK AND RIGHTS--Preferred Stock and
  Preference Stock."

  SHAREHOLDER OR STOCKHOLDER APPROVAL OF MERGERS AND ASSET SALES

       In addition to being subject to the laws of Texas and Delaware,
  respectively, as discussed below, both Bancorp and Norwest, as bank holding
  companies, are subject to various provisions of federal law with respect to
  mergers, consolidations and certain other corporate transactions.  See
  "CERTAIN REGULATORY CONSIDERATIONS PERTAINING TO NORWEST."

       BANCORP.  The TBCA requires certain mergers to be approved by holders of
  at least two-thirds of the outstanding shares entitled to vote thereon, unless
  there is a class of stock that is entitled to vote as a class, in which event
  the merger must be approved by the holders of two-thirds of the outstanding
  shares of each class of stock entitled to vote as a class and by the holders
  of two-thirds of the outstanding shares otherwise entitled to vote; provided
  that the articles of incorporation may require a vote of a different number,
  not less than a majority, of the shares outstanding.  The Bancorp Articles do
  not provide for a different number of shares for approval of a merger.  For
  that reason, as described above, the affirmative vote of at least two-thirds
  of the Bancorp Common Stock is required for a merger with Norwest.

       NORWEST.  Except as described below, the affirmative vote of a majority
  of the outstanding shares of Norwest Common Stock entitled to vote thereon is
  required to approve a merger or consolidation involving Norwest or the sale,
  lease or exchange of all or substantially all of Norwest's corporate assets.
  No vote of the stockholders is required, however, in connection with a merger
  in which Norwest is the surviving corporation and (i) the agreement of merger
  for the merger does not amend in any respect the Norwest Certificate, (ii)
  each share of capital stock outstanding immediately before the merger is to be
  an identical outstanding or treasury share of Norwest after the merger, and
  (iii) the 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 Norwest's capital stock
  outstanding immediately before the merger.

                                      28
<PAGE>
 
  APPRAISAL RIGHTS

       BANCORP.  Shareholders of Texas corporations are entitled to exercise
  certain dissenters' 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, and with the exception discussed below, a merger or
  consolidation.  Under Section 5.11 of the TBCA, however, shareholders do not
  have dissenters' rights if, in connection with a merger, the stock of the
  corporation held by the shareholder 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 shareholder is not required to accept for
  his 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.  A Bancorp shareholder will receive merger consideration that
  satisfies the provisions of subsections (a) and (b) above; however, because
  the Bancorp Common Stock is not listed on a national securities exchange and
  is held of record by fewer than 2,000 holders, dissenters rights will be
  available to Bancorp shareholders.  See "THE MERGER--Dissenters' Rights."

       NORWEST.  Section 262 of the DGCL provides for stockholder appraisal
  rights in connection with mergers and consolidations 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 merger or
  consolidation, were either (i) 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 (ii) 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.  Norwest Common Stock
  is listed on the NYSE and the CHX and currently held by more than 2,000
  stockholders.  For these reasons, assuming that the other conditions described
  above are satisfied, holders of Norwest Common Stock will not have appraisal
  rights in connection with mergers and consolidations involving Norwest.

  SPECIAL MEETINGS

       BANCORP.  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 ten
  percent (10%) of all shares entitled to vote at the meeting, unless a
  different percentage, not to exceed fifty percent (50%), is provided for in
  the articles of incorporation.

       NORWEST.  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.  The Norwest 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 the Norwest Board.  As
  such, holders of Norwest Common Stock do not have the ability to call a
  special meeting of stockholders.

  ACTION WITHOUT A MEETING

       BANCORP.  Under the TBCA, shareholders may act without a meeting if a
  consent in writing to such action is signed by all shareholders; provided,
  however, that the articles of incorporation may provide that any action
  required or permitted to be taken at a shareholder's 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 shareholders.

                                      29
<PAGE>
 
       NORWEST.  As permitted by Section 228 of the DGCL and the Norwest
  Certificate, 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.

  LIMITATION OF DIRECTOR LIABILITY

       BANCORP.  The Texas Miscellaneous Corporation Laws Act permits a
  corporation to set limits on the extent of a director's liability.  The
  Bancorp Articles limit, to the fullest extent now or hereafter permitted by
  the TBCA, liability of Bancorp's directors to Bancorp or its shareholders for
  monetary damages for a breach of such director's fiduciary duty.  This
  provision presently limits a director's liability except for (1) a breach of
  duty of loyalty to Bancorp or its shareholders, (2) a failure to act in good
  faith that constitutes a breach of duty to Bancorp or where a director engages
  in intentional misconduct or knowingly violates the law, (3) a transaction
  from which the director obtains an improper benefit, and (4) an act or
  omission for which liability is expressly provided for by statute.

       NORWEST.  The Norwest Certificate provides that a director (including an
  officer who is also a director) of Norwest shall not be liable personally to
  Norwest or its stockholders for monetary damages for breach of fiduciary duty
  as a director, except for liability arising out of (i) any breach of the
  director's duty of loyalty to Norwest or its stockholders, (ii) acts or
  omissions not in good faith or which involve intentional misconduct or a
  knowing violation of law, (iii) payment of a dividend or approval of a stock
  repurchase in violation of Section 174 of the DGCL, or (iv) any transaction
  from which the director derived an improper personal benefit.  This provision
  protects Norwest'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 availability of equitable remedies, such
  as an injunction or rescission, based upon a director's breach of his duty of
  care.

  INDEMNIFICATION OF OFFICERS AND DIRECTORS

       BANCORP.  TBCA provides that a corporation may indemnify an individual
  only if the individual (i) acted in good faith, (ii) in a manner he reasonably
  believed, in the case of conduct in his official capacity, was in the
  corporation's best interests and, in all other cases, that his conduct was at
  least not opposed to the corporation's interests, and (iii) in the case of any
  criminal proceeding, had no reasonable cause to believe that his conduct was
  unlawful.  The Bancorp Articles provide that directors shall be indemnified,
  and officers and employees may be indemnified against liabilities arising from
  their service as directors, officers, (or serving at the request of Bancorp as
  director, officer, partner, venturer, proprietor, trustee, employee, agent, or
  similar functionary of another entity) to the fullest extent permitted by law,
  including (upon receipt of a written affirmation of such individual's good
  faith belief that he has met the standard of conduct required for
  indemnification, and an undertaking to repay such advances if the officer or
  director is found to have not met the required standard of conduct) payment in
  advance of a final disposition of a director's or officer's expenses and
  attorneys' fees incurred in defending any action, suit or proceeding, other
  than in the case of an action, suit or proceeding brought about by Bancorp on
  its own behalf against an officer.  See THE MERGER"--Interests of Certain
  Persons in the Merger."

       NORWEST.    The Norwest Certificate provides that Norwest must indemnify,
  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 Norwest (or
  was serving at the request of Norwest 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 the Norwest Board.  The Norwest Certificate also provides that Norwest 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 

                                      30
<PAGE>
 
  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.

       The Norwest Certificate authorizes Norwest to provide similar
  indemnification to employees or agents of Norwest.

       Pursuant to the Norwest Certificate, Norwest may maintain insurance, at
  its expense, to protect itself and any directors, officers, employees or
  agents of Norwest or another entity against any expense, liability or loss,
  regardless of whether Norwest 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 the Norwest
  Certificate or Norwest Bylaws, agreement, vote of stockholders or
  disinterested directors or otherwise.

  DIVIDENDS

       In addition to restrictions imposed under Texas and Delaware law,
  respectively, as discussed below, Norwest and Bancorp are subject to Federal
  Reserve Board policies regarding payment of dividends, which generally limit
  dividends to operating earnings. See "CERTAIN REGULATORY CONSIDERATIONS
  PERTAINING TO NORWEST."

       BANCORP.  Under the TBCA, a Texas corporation may make distributions only
  out of surplus.  Holders of Bancorp Common Stock are entitled to receive
  dividends ratably when, as and if declared by the Bancorp Board from assets
  legally available therefor, after payment of all dividends on Bancorp
  preferred stock.

       NORWEST.  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 profits if, after the payment of the
  dividend, capital is less than the capital represented by the outstanding
  stock of all classes having a preference upon the distribution of assets.

  PROPOSAL OF BUSINESS, NOMINATION OF DIRECTORS

       BANCORP.  The Bancorp Bylaws provide that special meetings of
  shareholders of Bancorp may be called by the Chairman of the Board, the
  President, the Board of Directors, or holders of at least ten percent of the
  outstanding shares.

       NORWEST.  The Norwest Bylaws contain detailed advance notice and
  informational procedures which must be complied with in order for a
  stockholder to nominate a person to serve as a director.  The Norwest Bylaws
  generally require a stockholder to give notice of a proposed nominee in
  advance of the stockholders meeting at which directors will be elected.  In
  addition, the Norwest Bylaws contain detailed advance notice and informational
  procedures which must be followed in order for a Norwest stockholder to
  propose an item of business for consideration at a meeting of Norwest
  stockholders.

                        INFORMATION CONCERNING BANCORP

       Bancorp derives all of it revenues and income from the operation of Texas
  Bank.  Texas Bank provides a full range of commercial and consumer banking
  services to individuals and small and middle market businesses in the Permian
  Basin as well as Central Texas.  Texas Bank operates two full service branches
  in Odessa, Texas, two in Austin, Texas, and one each in Pflugerville, Dripping
  Springs, Burnet, Kingsland, and Buchanan Dam, Texas.

  TEXAS BANK

       Texas Bank conducts a general commercial and consumer banking business,
  which includes the acceptance of deposits from consumers and the origination
  of commercial, real estate, installment, and other loans.  Texas Bank also
  provides investment services through an outside vendor, Investment
  Professional Services, Incorporated.  Deposit services include certificates of
  deposit, individual retirement accounts and other time deposits, checking and
  other demand deposit accounts, interest-bearing checking accounts, savings
  accounts, and money market accounts.  Loans consist of commercial loans to
  small and middle market businesses, loans to individuals, and commercial real
  estate loans, residential mortgage loans, and construction loans.

       Although Texas Bank provides a full range of commercial and consumer
  banking services, it also seeks to distinguish itself in the products and
  services it offers.  Texas Bank, with nine full service banking facilities, 
  25 drive-through lanes, and eight strategically located ATMs in the various
  communities it serves, has historically provided banking services to small and
  middle market businesses and individuals.  Texas Bank originated in 1982 as
  Texas National Bank of Odessa to develop a strong community identity and name
  recognition.  As part of its community focus, Texas Bank has implemented
  certain banking programs specially tailored to the needs of its customers.
  Texas Bank has distinguished itself in the SBA lending arena by being elevated
  to "Preferred Lender" status by the SBA, which few institutions have achieved.
  Texas Bank has also developed a particular market in each of its communities
  related to the purchase of indirect installment loans (dealer paper).  As of
  December 31, 1995 this dealer paper amounted to 11.81% of Texas Bank's total
  loans outstanding.  This type of installment financing is attractive due to
  its higher than average yields as well as relatively short maturities.

       In 1990 and 1991 Texas Bank entered into purchase and assumption
  agreements with the FDIC to purchase the failed Southwest National Bank,
  Austin, Texas and Dripping Springs National Bank, Dripping Spring, Texas.  As
  part of these transactions Texas Bank assumed a substantial part of the
  deposit liabilities of the failed organizations and acquired most of the
  assets of those organizations.  Texas Bank's winning bids on these
  organizations permitted the Bank to purchase the failed banks' loans at a
  discount from the outstanding loan balances.  This discount has been used in
  part to offset losses in the assets acquired, particularly the loan portfolio,
  and in part to accrete into income and has a balance as of December 31, 1995
  of approximately $937,000.

       In 1995, Bancorp acquired the outstanding common stock of Lake Buchanan
  State Bank, a state chartered bank in Buchanan Dam, Texas.  Lake Buchanan
  State Bank was merged into Texas Bank in April 1995.

  NONBANKING ACTIVITIES

       Bancorp does not engage in any activities or businesses other than the
  ownership of Texas Bank.  Texas Bank currently leases space to Investment
  Professionals Incorporated ("IPI") of San Antonio, Texas, which is a full
  service broker dealer in all types of securities.  IPI provides a full range
  of investment opportunities for customers of Texas Bank in a separately
  identified area in the lobby of the Bank.  Currently two brokers are employed
  by IPI which work solely in the offices of Texas Bank.  One employee covers
  the two Odessa facilities and the other employee rotates among all seven of
  the Central Texas branches.  Total IPI rental income for 1995 amounted to
  $104,000.

  COMPETITION

       Texas Bank encounters strong competition in making loans and attracting
  deposits.  The state of Texas permits statewide branch banking and statewide
  savings and loan branching.  Moreover, Texas Bank competes with other
  commercial and savings banks, savings and loan associations, credit unions,
  finance companies, mutual funds, insurance companies, brokerage and investment
  banking companies, and certain other nonfinancial institutions in the Permian
  Basin and Central Texas area.  The continued liberalization of the banking and
  securities industries may also increase competitive pressures on Texas Bank.

       Management of Texas Bank believes it is well positioned to compete
  successfully in its primary market areas, although no assurances can be given
  in this regard.  Competition among financial institutions is based upon
  interest rates offered on deposit accounts, interest rates charged on loans,
  other credit and service charges, the quality and scope of the services
  offered, the convenience of banking facilities, and, in the case of loans to
  commercial borrowers, relative lending limits.  In particular, Texas Bank
  expects to encounter continued and increased competition in the indirect
  dealer paper market, mortgage loan generation, and SBA lending areas.
  Management believes, however, that Texas Bank's long-term presence, local
  expertise, and ongoing commitment to the community, as well as its commitment
  to quality and personalized banking services, are factors that contribute to
  the Bank's competitiveness.

  REGULATION AND SUPERVISION

       REGULATION OF BANCORP.  Bancorp is a bank holding company within the
  meaning of the Bank Holding Company Act and therefore is subject to regulation
  and supervision by the Federal Reserve Board.  As such, Bancorp is required to
  file reports with and furnish such other information as the Federal Reserve
  Board may require pursuant to the Bank Holding Company Act, and to subject
  itself to examination by the Federal Reserve Board.

       As a bank holding company, Bancorp is required to obtain approval prior
  to merging or consolidating with any other bank holding company, acquiring all
  or substantially all of the assets of any bank or acquiring ownership of
  shares of a bank or bank holding company if, after the acquisition, Bancorp
  would directly or indirectly own or control 5% or more of the voting shares of
  such bank or bank holding company.

       Bancorp is also prohibited from acquiring a direct or indirect interest
  in or control of more than 5% of the voting shares of any company which is not
  a bank or bank holding company and from engaging directly or indirectly in
  activities other than those of banking, managing or controlling banks or
  furnishing services to its subsidiary banks, except that it may engage in and
  may own shares of companies engaged in certain activities found by the Federal
  Reserve Board to be so closely related to banking or managing and controlling
  banks as to be a proper incident thereto.

       Under the Bank Holding Company Act and the Federal Reserve Board's
  regulations, a bank holding company and its subsidiaries are 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 TEXAS BANK.  Texas Bank is a state banking association and
  is therefore subject to regulation, supervision, and examination by the Texas
  Department of Banking (the "Banking Department") and the FDIC.  Texas Bank is
  also a member of the FDIC.  Requirements and restrictions under the laws of
  the state of Texas and the United States include the requirement that reserves
  be maintained against deposits, restrictions on the nature and the amount of
  loans which can be made, restrictions on the business activities in which a
  bank may engage, restrictions on the payment of dividends to stockholders, and
  minimum capital requirements.

       There are certain limitations on the payment of dividends by Texas state
  banks.  At December 31, 1995, approximately $2,148,000 was available for
  declaration of dividends by Texas Bank without prior regulatory approval.

                                      33
<PAGE>
 
       The Banking Department and the FDIC are authorized by legislation to take
  various enforcement actions against any significantly undercapitalized state
  bank and any state bank that fails to submit an acceptable capital restoration
  plan or fails to implement a plan accepted by the FDIC.  Based on its capital
  ratio as of December 31, 1995, Texas Bank was classified as "well capitalized"
  under the applicable regulations.

       CURRENT REGULATORY ISSUES. Under the Federal Reserve Board's risk-based
  capital guidelines for bank holding companies, Bancorp is required to maintain
  minimum Tier 1 and total capital to risk-adjusted assets ratios of 4% and 8%,
  respectively, and a minimum "leverage ratio" of 3%.  At June 30, 1996 and
  December 31, 1995 and 1994, Bancorp's Tier 1 and total capital to risk-
  adjusted assets ratio and its leverage ratio were as follows:

  For a general discussion of the Federal Reserve Board's risk-based capital
  guidelines and the criteria applied to calculate the ratios, see "CERTAIN
  REGULATORY CONSIDERATIONS PERTAINING TO NORWEST - Capital Requirements."  For
  information concerning similar risk-based capital ratios for Texas Bank, see
  "INFORMATION CONCERNING BANCORP--Capital Resources."

       Effective January 1, 1993, the FDIC imposed deposit premiums based on a
  risk-based assessment system, requiring well capitalized institutions to pay
  $0.23 per $100 of insured deposits.  The rates increased incrementally to a
  top rate of $0.31 per $100 of deposits for the weakest banks.  Based on the
  risk category applicable to Texas Bank through June 1995, the premium paid by
  it was $0.23 per $100 of deposits.

       In August 1995, the FDIC voted to reduce significantly the deposit
  insurance premiums paid by institutions insured by the Bank Insurance Fund
  ("BIF") to a range of 4 to 31 basis points per $100 of deposits.  On September
  15, 1995, the FDIC refunded overpayments on insurance premiums for the months
  June through September 1995, and Texas Bank was assessed a rate of 4 basis
  points per $100 of deposits for the fourth quarter of 1995.

       On November 14, 1995 the FDIC approved reducing the assessment rates
  applicable to BIF-insured institutions to a range of zero to 27 basis points
  from the previous range of 4 to 31 basis 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.  Texas Bank was
  within the Subgroup A category as of December 31, 1995.  For a general
  discussion concerning the criteria applied by the FDIC to determine an
  institution's insurance premium assessment rate, see "CERTAIN REGULATORY
  CONSIDERATIONS PERTAINING TO NORWEST--FDIC Insurance."

       In December 1991, the Federal Deposit Insurance Corporation Improvement
  Act of 1991 ("FDICIA") was signed into law by President Bush.  FDICIA
  increased the regulatory burden on financial institutions and imposed
  substantial actual and incidental costs on the institutions and their
  customers.  See "CERTAIN REGULATORY CONSIDERATIONS PERTAINING TO NORWEST--
  Federal Deposit Insurance Corporation Improvement Act of 1991."

  LEGAL PROCEEDINGS

       Bancorp and Texas Bank are parties to or otherwise involved in legal
  proceedings arising through the normal course of business, such as claims to
  enforce liens, claims related to making and servicing real property loans, and
  other issues incident to the business of Bancorp and Texas Bank. Management

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
  OPERATIONS

       SIX MONTHS ENDED JUNE 30, 1996 AND 1995

       Bancorp experienced net income through June 30, 1996 of $1,638,000, as
  compared to $1,144,000 for the same period ending June 30, 1995, which
  represents a 43.18% increase in net income. The net income per share for the
  six months ending June 30, 1996 was $1.90 compared to $1.33 for the same
  period ending June 30, 1995. Net income for June 30, 1996 represents an
  annualized return on equity of 21.98% compared to 18.45% for the same period
  in the preceding year. This net income also represents a return on assets of
  1.96% for the period ending June 30, 1996 as compared to 1.54% for the period
  ending June 30, 1995. The contributing factors for the increase in 1996 was a
  24.54% increase in net interest income, as well as a 24.42% increase in non
  interest income, principally service charges.

       Bancorp experienced net loan growth of $13,194,000 for the first six
  months of 1996.  Loan to deposit ratio as of June 30, 1996 was 72% compared to
  65% as of December 31, 1995.  Total deposits as of June 30, 1996 were
  $150,977,000 as compared to deposits of $147,688,000 at December 31, 1995.

       YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993

       LOAN ANALYSIS AND RECAPS.  Texas Bank has concentrated its efforts in
  lending in the area of middle market businesses and individual relationships
  over the past ten years.  In doing so the Bank has had heavy concentration in
  SBA loans as well as indirect automobile loan purchases.  Accordingly Texas
  Bank has been able to maintain a loan to deposit ratio in excess of 55% and
  often as high as 65% over the course of the past six years with only small
  declines due to unexpected growth in the deposit generating side of the Bank.
  The underwriting standards of the Bank have evolved through the modification
  of the loan policy and administration of lending activities through Bank
  committees and have resulted in a continued improvement in the quality of the
  assets carried in the loan portfolio over the course of the past ten years.
  Assets with a book value of approximately $1,323,000 representing 10.76% of
  Texas Bank's Tier 1 capital are currently included on the Bank's internal
  watch list.

       PROVISION FOR LOAN LOSSES.  Provisions for loan losses are charged to
  earnings to bring the total of the allowance for loan losses to a level deemed
  appropriate by management based on such factors as historical experience,
  volume and type of lending conducted by the Bank, the amount of non-performing
  assets, regulatory policies, general economic conditions, and other factors
  related to the collectibility of loans in the Bank's portfolio.  On January 1,
  1995, Texas Bank adopted the provisions of Statement of Financial Accounting
  Standards 114 (SFAS-114), "Accounting by Creditors for Impairment of a Loan,"
  as amended by the Statement of Financial Accounting Standards 118 (SFAS-118),
  "Accounting by Creditors for Impairment of a Loan - Income Recognition and
  Disclosures."  These statements require impairment of non-performing loans to
  be measured based on the present value of expected future cash flows
  discounted at the loan's effective interest rate, its observable market value,
  or the fair value of the collateral if the loan is collateral dependent.  The
  provision for loan losses for the year ended December 31, 1995 was determined
  in accordance with the statements, the adoption of which did not have a
  significant impact on Texas Bank's financial position or its results of
  operations for the year then ended.  The provision for loan losses for the
  year ended December 31, 1995 was $378,000, an increase of 58.16% compared to
  the provision for loan losses for the year 1994.  The provision for loan
  losses of $239,000 in 1994 represented a decrease of 8.08% compared with the
  provision for loan losses of $260,000 for 1993.  All losses embedded in the
  portfolios of the two failed banks acquired from the FDIC were absorbed by the
  discount incorporated into Texas Bank's bid for such failed banks and have not
  been charged to the allowance for loan losses.  Since 1990 the economies of
  central Texas and the Permian Basin have continued to improve to the point
  that many of the loans which were impaired in the early 1990s have now been
  moved off the balance sheet by way of foreclosure or payoff while many others
  have rehabilitated themselves due to increased performance and ability to
  service debt by the borrower.  These improvements have far exceeded
  management's expectations for the six year period and at this  

                                      37
<PAGE>
 
  time management foresees no need to continue to increase the provision for
  loan losses except in a fashion which will fully reserve for growth in the
  loan portfolio in all the branches.

       LOAN AND ASSET QUALITY. Loans (before purchase discounts) as of December
  31, 1995 were $100,162,000, representing an increase of $23,565,000 or 30.77%
  from $76,597,000 at the end of 1994. The increase was evenly spread throughout
  the portfolio in the areas of commercial, commercial real estate, mortgage,
  and installment loans, with only construction lending decreasing slightly over
  the course of the year. The strong loan demand in both the Permian Basin and
  Austin area is directly attributable to the improved economy in the two areas
  and the stabilization of the oil and gas economy of the Permian Basin as well
  as the real estate and high tech industries in Central Texas. The volume of
  Texas Bank's loans has steadily increased since 1992 after a slight decline
  from 1991 to 1992 primarily due to problem credits acquired through the two
  failed bank transactions being dealt with during that year. The main growth in
  the commercial area has been in the area of SBA lending due to the ability to
  sell the guaranteed portion of the SBA loans into the secondary market,
  creating further liquidity for the Bank. Additionally, as those loans are
  generally sold at a premium over book value, additional income over and above
  the normal interest income is realized.

       Installment and other loans have continued to increase over the years
  with the largest increase between 1993 and 1994 from $15,729,000 to
  $22,238,000 and further increase to $27,749,000 in 1995. A large portion of
  this growth is attributable to the indirect dealer paper which poses
  additional risks in collectibility compared with the more traditional type of
  loans such as residential mortgage loans.  In many instances the Bank is
  required to rely on the borrower's ability to repay since the collateral may
  have reduced value at the time of collection.  Historically Texas Bank has
  taken greater losses in the indirect portfolio as indicated by the allowance
  for loan loss increase over the course of the past three years from $909,443
  in 1993 to $1,031,671 in 1995. Net charge offs for the year as a percentage
  average loans have equated to .18%, .34%, and .39% in 1993, 1994, and 1995
  respectively.  As the allowance for loan losses has increased and as the loan
  portfolio has improved, the coverage of the allowance as a percentage of non-
  performing assets has improved from 54.6% in 1991 to 115.2% in 1995.  Once
  again the primary reason for improvement is based on the improvement of the
  overall portfolio and the economic conditions surrounding the Bank.

       Loan concentration is defined as an amount loaned to a number of
  borrowers engaged in similar activities or resident in the same geographic
  region which would cause them to be similarly affected by economic and other
  conditions. Texas Bank on a routine basis evaluates these kinds of
  concentrations for the purpose of policing its concentrations and makes
  necessary adjustments in its lending practices. Such adjustments help ensure
  that its lending practices clearly reflect current economic conditions, loan
  to deposit ratios, and industry trends. As a result of the Bank's market
  focus, Texas Bank has significant concentration in assets in the Austin
  metropolitan area as well as Midland-Odessa. The following table sets forth
  the composition of Texas Bank's loan portfolio by type of loan on the dates
  indicated.

       NONPERFORMING ASSETS.  Generally, interest on loans is accrued and
  credited to income based upon the principal balance outstanding.  It is
  management's policy to discontinue the accrual of interest income when
  principal or interest is past due 90 days or more and the loan is not
  adequately collateralized, or when in the opinion of management, principal or
  interest is not likely to be paid in accordance with the terms of the
  obligation.  The Bank will generally charge-off loans after 120 days of
  delinquency unless adequately collateralized and in process of collection.  A
  loan is considered in the process of collection if, based on a probable
  specific event, management believes that the loan will be repaid or brought
  current.  Loans will not be returned to accrual status until future payments
  of principal and interest appear certain.  Interest accrued and unpaid at the
  time a loan is placed on non-accrual status is charged against interest
  income.  Subsequent payments received are applied to the outstanding principal
  balance.

       Real estate acquired by the Bank as a result of foreclosure or by deed in
  lieu of foreclosure is classified as OREO.  Such loans are reclassified to
  OREO and recorded at the 

                                      39

  lower of cost or fair market value less estimated selling costs, and the
  estimated loss, if any, is charged to the allowance for loan losses at that
  time. Further losses are recorded as charges to other expenses at the time
  management believes additional deterioration in value has occurred.

       The following table sets forth certain information with respect to the
  Bank's impaired loans, accruing loans which are contractually past due 90 days
  or more as to principal or interest, and OREO.

  (1)  $506,000 of this amount is an SBA loan of which 82% of the principal
       balance and related interest is guaranteed by the SBA.

       Interest payments received on impaired loans are recorded as interest
  income unless collection of the remaining recorded investment is doubtful, at
  which time payments received are recorded as reductions of principal. Interest
  that would have been accrued on impaired loans during 1995 was approximately
  $90,000. Interest income that would have been accrued on nonaccrual loans
  during 1994 and 1993 was approximately $28,000 and $37,000, respectively.
  Interest income recognized during 1994 and 1995 on impaired loans was
  approximately $131,000 and $22,000, respectively.

       Management regularly reviews and monitors the loan portfolio in order to
  identify borrowers experiencing financial difficulties. Management believes
  that as of December 31, 1995, all such loans had been identified and included
  in the non-accrual or 90 days past due loan totals reflected in the above
  table. Management continues to emphasize maintaining a low level of
  nonperforming assets and returning nonperforming assets to an earning status
  as performance and conditions permit.

       OREO at December 31, 1995 consisted of one residential property with a
  carrying amount of $70,000. This property has an appraised value of $180,000
  and is being marketed by the Bank. Based on current real estate market
  conditions, management believes that the future aggregate recoveries on
  disposals of OREO will exceed the net book carrying amount of such OREO as of
  December 31, 1995. In the past five years OREO has not constituted a
  significant balance sheet item for the Bank as no large foreclosures have
  occurred nor has any property been held for any extended period of time during
  the past five years. Currently Texas Bank markets its OREO in local markets
  with the services of local realtors.

       ALLOWANCE FOR LOAN LOSSES.  In originating loans, the Bank recognizes
  that credit losses will be experienced and the risk of loss will vary with,
  among other things, general economic conditions, the type of loan being made,
  the creditworthiness of the borrower over the term of the loan and, in the
  case of a collateralized loan, the quality of the collateral for such loan.
  Management maintains an allowance for loan losses based upon, among other
  things, historical experience, an evaluation of economic conditions, regular
  review of delinquencies, and its evaluation of loan portfolio quality. In
  addition to unallocated allowances, specific allowances

                                      40
<PAGE>
 
are provided for individual loans when ultimate collection is considered
questionable by management after reviewing the current status of loans which are
contractually past due and considering the net realizable value of the
collateral for the loan. On January 1, 1995, Texas Bank adopted the provisions
of SFAS-114 and SFAS-118, and determined the provision for loan losses for 1995
in accordance with the requirements of these statements. See "Provision for Loan
Losses."

     Management continues to actively monitor the Bank's asset quality and to
charge off loans against the allowance for loan losses when appropriate or to
provide specific loss allowances when necessary. Although management believes it
uses the best information available to make determinations with respect to the
allowance for loan losses, future adjustments may be necessary if economic
conditions differ from the assumptions used in making the initial
determinations.

     The following table sets forth an analysis of the Bank's allowance for loan
losses for the periods indicated.

     The following table sets forth the breakdown of the allowance for loan
losses by loan category for the periods indicated. Management believes that the
allowance can be allocated by category only on an approximate basis. The
allocation of an allowance to each category is not necessarily indicative of
future losses and does not restrict the use of the allowance to absorb losses in
any other category.

       INVESTMENT ACTIVITIES. Texas Bank's investments as of December 31, 1995
consisted primarily of United States Treasury securities, federal agency
obligations, collateralized mortgage obligations, and mortgage-backed
securities. The mortgage-backed securities represent an interest in a pool of
underlying mortgages, and are all issued by United States government agencies.
These securities may be more sensitive to changes in interest rates and income
derived from such securities may be adversely affected by prepayments of
principal on the underlying mortgages. The total portfolio value of December 31,
1995 was $37,000,000 at amortized cost and a market value of $36,822,000
resulting in a net depreciation of $178,000 on the total portfolio.

       The following table sets forth the book value of Texas Bank's investment
portfolio as of the dates indicated. Investment securities held to maturity are
stated at cost, adjusted for amortization of premium and accretion of discount.
Investment securities available for sale are stated at fair value in accordance
with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities". See " - Accounting Matters" and Note C of the Notes to Consolidated
Financial Statements.

       Since the adoption of SFAS-115 the Bank has chosen to carry most or all
of its securities in the available for sale category to allow the portfolio to
be liquidated at any point in time. Due to the short maturities of most of the
obligations as well as relatively high dependence on variable rate securities
tied to various indices, the board of directors of the Bank believes that
maintaining high liquidity in the portfolio outweighs the potential realizable
loss that the portfolio might have at any given time.

       The following table sets forth the maturity distribution and weighted
average yield of the investment portfolio of Texas Bank as of December 31, 1995.
The calculation of the weighted average yields is based on yield, weighted by
the respective costs of the securities.

       LIQUIDITY.  Bancorp's principal source of funds consists of dividends
  from Texas Bank, which derives its funds from deposits, interest and principal
  payments on loans and investment securities, sales of investment securities
  and borrowings. For the year ended December 31, 1995, Texas Bank realized
  proceeds from sale and maturity of investments of $22,171,557, a net increase
  of deposits of $16,828,122 and net cash provided by operating activities of
  $3,257,752. Funds were used to acquire investment securities of $20,305,779,
  and fund a net increase in loans to customers of $10,944,201. Additionally,
  Bancorp paid a total of $500,000 in dividends to common shareholders in 1995.
  For the year ended December 31, 1994 Texas Bank realized proceeds from sale
  and maturity of investment securities of $11,701,932, net cash provided by
  operating activities of $1,110,682, and net increase of deposits of
  $6,608,479. These proceeds were partially offset by a purchase of investment
  securities of $7,432,026 and net increase in loans to customers of
  $12,214,452. During the year 1994 Bancorp paid $1,000,000 in dividends to
  common shareholders.

       Asset liquidity is provided by cash and assets which are readily
  marketable, which can be pledged, or which will mature in the near future.
  These include cash, federal funds sold, and U.S. Government-backed securities.
  Texas Bank's liquidity ratio, defined as cash, U.S. Government-backed
  securities, and federal funds sold as a percentage of total deposits, was
  40.26%, 40.36%, and 50.15% as of December 31, 1995, 1994, 1993, respectively.
  Liability liquidity is provided by access to core funding sources, principally
  various customers' interest-bearing deposit accounts in Texas Bank's market
  areas. The Bank does not have and does not solicit brokered deposits.

       Federal funds purchased and short-term borrowings by the Bank are
  additional sources of liquidity. These sources of liquidity are short-term in
  nature and are used by the Bank as necessary to fund asset growth and meet
  short-term liquidity needs. As of December 31, 1995 and 1994, the Bank had no
  federal funds purchased, no borrowings from the Federal Reserve System, and no
  borrowings on securities sold under repurchase agreements.

       CAPITAL RESOURCES.  Bancorp's total shareholders' equity as of December
  31, 1995 was $13,548,000, an increase of $3,274,000 or 31.87% compared with
  shareholders' equity of $10,274,000 on December 31, 1994. The total increase
  was attributable to earnings, a change in unrealized loss on debt securities
  available for sale, net of tax, and a dividend paid.

       Total shareholders' equity as of December 31, 1994 was $10,274,000, an
  increase of $1,154,000 or 12.65% compared with shareholders' equity of
  $9,120,000 as of December 31, 1993. The total increase was attributable to
  earnings and unrealized loss on debt securities available for sale, net of
  tax.

       The Federal Reserve Board has established certain minimum risk-based
  capital standards that apply to bank holding companies. As of December 31,
  1995 Bancorp's Tier 1 risk-based capital ratio was 9.99%, its total risk-based
  capital ratio was 10.96% and its leverage capital ratio was 8.33%. As of
  December 31, 1994 Bancorp's Tier 1 risk-based capital was 11.37%, its total-
  risk based capital ratio was 12.53%, and its leverage capital ratio was 7.73%.

       ACCOUNTING MATTERS.

            ACCOUNTING FOR LOAN IMPAIRMENT.  Effective January 1, 1995 Bancorp
  adopted SFAS-114 and SFAS-118.  See "Provision for Loan Losses."  The adoption
  of these statements did not have a significant impact on Bancorp's financial
  position nor its results of operations for the year ended December 31, 1995.

            ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES.
  In May 1993, the FASB issued Statement of Financial Accounting Standards No.
  115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS
  No. 115").  SFAS No. 115 addresses the accounting and reporting for
  investments in equity securities that have readily determinable fair values
  and for all investments in debt securities.  Those investments are to be
  classified in one of three categories:  (i) debt securities that the
  enterprise has the positive intent and ability to hold to maturity are
  classified as "held-to-maturity securities", and are reported at amortized
  cost; (ii) debt and securities that are bought and held principally for the
  purpose of selling them in the near term are classified as "trading
  securities" and are reported at fair value, with unrealized gains and losses
  included in earnings; and (iii) debt and equity securities not classified as
  either held-to-maturity securities or trading securities are classified as
  "available-for-sale securities" and are reported at fair value, with
  unrealized gains and losses excluded from earnings and reported in a separate
  component of stockholders' equity.  Bancorp adopted SFAS No. 115 as of January
  1, 1994.

            IMPACT OF INFLATION, CHANGING PRICES, AND MONETARY POLICIES.  The
  financial statements and related financial data concerning Bancorp 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
  Bancorp 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
  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
  prices.  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 the Bank,
  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 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 affect the interest rates charged on loans 

                                      45

  and paid on deposits. The nature, timing and impact of any future changes in
  federal monetary and fiscal policies on Bancorp and Texas Bank and their
  results of operations are not predictable.

                       CERTAIN REGULATORY CONSIDERATIONS
                             PERTAINING TO NORWEST
                                        
  GENERAL

       As a bank holding company, Norwest is subject to supervision and
  examination by the Federal Reserve Board. Under the Bank Holding Company Act,
  a bank holding company generally may not directly or indirectly acquire the
  ownership or control of more than 5% of the voting securities or all or
  substantially all of the assets of any company, including a bank, without the
  prior approval of the Federal Reserve Board. In addition, a bank holding
  company is generally prohibited under the Bank Holding Company Act from
  engaging in nonbanking activities, subject to certain exceptions. Various
  proposals are pending before Congress that would allow affiliations between a
  bank holding company and nonbank entities that are prohibited or restricted
  under current law. Whether Congress will adopt any of these proposals, and if
  so in what form, is not known at this time.

       Norwest's banking and savings association subsidiaries are subject to
  supervision and examination by applicable federal and state banking agencies.
  The deposits of Norwest's banking subsidiaries are primarily insured by the
  Bank Insurance Fund; deposits attributable to certain of Norwest's savings
  associations are insured by the Savings Association Insurance Fund (the
  "SAIF"). For that reason, such banking subsidiaries are subject to regulation
  by the FDIC. In addition to the impact of regulation, commercial banks are
  affected significantly by the actions of the Federal Reserve Board as it
  attempts to control the money supply and credit availability in order to
  influence the economy.

  DIVIDEND RESTRICTIONS

       Various federal and state statutes and regulations limit the amount of
  dividends the subsidiary banks can pay to Norwest without regulatory approval.
  The approval of the OCC is required for any dividend by a national bank if the
  total of all dividends declared by the bank in any calendar year would exceed
  the total of its net profits, as defined by regulation, for that year combined
  with its retained net profits for the preceding two years less any required
  transfers to surplus or a fund for the retirement of any preferred stock. In
  addition, a national bank may not pay a dividend in an amount greater than its
  net profits then on hand after deducting its losses and bad debts. For this
  purpose, bad debts are defined to include, generally, loans which have matured
  and are in arrears with respect to interest by six months or more, other than
  such loans that are well secured and in the process of collection. Under these
  provisions Norwest's national bank subsidiaries could have declared, as of
  June 30, 1996, aggregate dividends of at least $219.6 million without
  obtaining prior regulatory approval and without reducing the capital of the
  banks below minimum regulatory levels. Norwest also has several state bank
  subsidiaries that are subject to state regulations limiting dividends;
  however, the amount of dividends payable by Norwest's state bank subsidiaries,
  with or without state regulatory approval, would represent an immaterial
  contribution to Norwest's revenues.

       If, in the opinion of the applicable regulatory authority, a bank under
  its jurisdiction is engaged in or is about to engage in an unsafe or unsound
  practice (which, depending on the financial condition of the bank, could
  include the payment of dividends), such authority may require, after notice
  and hearing, that such bank cease and desist from such practice. The Federal
  Reserve Board, the OCC, and the FDIC have issued policy statements which
  provide that FDIC-insured banks and bank holding companies should generally
  pay dividends only out of current operating earnings.

                                      47

  HOLDING COMPANY STRUCTURE

       Norwest is a legal entity separate and distinct from its banking and
  nonbanking subsidiaries. For that reason, the right of Norwest, and thus the
  rights of Norwest's creditors, to participate in any distribution of the
  assets or earnings of any subsidiary is necessarily subject to the prior
  claims of creditors of such subsidiary, except to the extent that claims of
  Norwest in its capacity as a creditor may be recognized. The principal sources
  of Norwest's revenues are dividends and fees from its subsidiaries.

       Norwest's banking subsidiaries are subject to restrictions under federal
  law which limit the transfer of funds by the subsidiary banks to Norwest and
  its nonbank subsidiaries, whether in the form of loans, extensions of credit,
  investments or asset purchases. Such transfers by any subsidiary bank to
  Norwest or any nonbank subsidiary are limited in amount to 10% of the bank's
  capital and surplus and, with respect to Norwest and all such nonbank
  subsidiaries, to an aggregate of 20% of such bank's capital and surplus.
  Furthermore, such loans and extensions of credit are required to be secured in
  specified amounts.

       The Federal Reserve Board has a policy to the effect that a bank holding
  company is expected to act as a source of financial and managerial strength to
  each of its subsidiary banks and to commit resources to support each such
  subsidiary bank. This support may be required at times when Norwest may not
  have the resources to provide it. Any capital loans by Norwest to any of the
  subsidiary banks are subordinate in right of payment to deposits and to
  certain other indebtedness of such subsidiary bank. In addition, the Crime
  Control Act of 1990 provides that in the event of a bank holding company's
  bankruptcy, any commitment by the bank holding company 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.

       A depository institution insured by the FDIC can be held liable for any
  loss incurred by, or reasonably expected to be incurred by, the FDIC after
  August 9, 1989 in connection with (i) the default of a commonly controlled
  FDIC-insured depository institution or (ii) any assistance provided by the
  FDIC to a commonly controlled FDIC-insured depository institution in danger of
  default. "Default" is defined generally as the appointment of a conservator or
  receiver and "in danger of default" is defined generally as the existence of
  certain conditions indicating that a "default" is likely to occur in the
  absence of regulatory assistance.

       Federal law (12 U.S.C. (S)55) permits the OCC to order the pro rata
  assessment of stockholders of a national bank whose capital stock has become
  impaired, by losses or otherwise, to relieve a deficiency in such national
  bank's capital stock. This statute also provides for the enforcement of any
  such pro rata assessment of stockholders of such national bank to cover such
  impairment of capital stock by sale, to the extent necessary, of the capital
  stock of any assessed stockholder failing to pay the assessment. Similarly,
  the laws of certain states provide for such assessment and sale with respect
  to banks chartered by such states. Norwest, as the sole stockholder of most of
  its subsidiary banks, is subject to such provisions.

  ACQUISITIONS

       Effective September 29, 1995, under the provisions of the Reigle-Neal
  Interstate Banking and Branching Act of 1994 (the "Reigle-Neal Act"),
  Norwest's banking subsidiaries are permitted to acquire banks located in any
  state in which the acquiring subsidiary bank is located (an intrastate
  merger). Effective June 1, 1997, Norwest's banking subsidiaries will be
  permitted to acquire a bank located in a state other than the state in which
  the acquiring subsidiary bank is located (an interstate merger) through
  merger, consolidation or purchase of assets and assumption of liabilities,
  unless the state in which either of the banks is located has opted out of the
  interstate banking provisions of the Reigle-Neal Act. An interstate merger may
  occur before June 1, 1997 if the states in which the merging banks are located
  have enacted a law authorizing interstate bank mergers.

                                      48
<PAGE>
 
       All of Norwest's acquisitions of banking institutions and other companies
  are subject to the prior approval of the Federal Reserve Board and any
  applicable federal or state regulatory authorities. In addition, under the
  provisions of the Reigle-Neal Act, bank mergers are subject to deposit
  concentration limits of 10% nationwide and 30% in any one state, unless it is
  Norwest's initial entry into the state.

  CAPITAL REQUIREMENTS

       Under the Federal Reserve Board's risk-based capital guidelines for bank
  holding companies, the minimum ratio of total capital to risk-adjusted assets
  (including certain off-balance sheet items, such as stand-by letters of
  credit) is 8%. At least half of the total capital is to be comprised of common
  stockholders' equity, minority interests and noncumulative perpetual preferred
  stock ("Tier 1 capital"). The remainder ("Tier 2 capital") may consist of
  hybrid capital instruments, perpetual debt, mandatory convertible debt
  securities, a limited amount of subordinated debt, other preferred stock, and
  a limited amount of the allowance for credit losses. The risk-based guidelines
  also specify that all intangibles, including core deposit intangibles, as well
  as mortgage servicing rights ("MSRs") and purchased credit card relationships
  ("PCCRs"), be deducted from Tier 1 capital. The guidelines, however,
  grandfather identifiable assets (other than MSRs and PCCRs) acquired on or
  before February 19, 1992 and permit the inclusion of readily marketable MSRs
  and PCCRs in Tier 1 capital to the extent that (i) MSRs and PCCRs do not
  collectively exceed 50% of Tier 1 capital and (ii) PCCRs do not exceed 25% of
  Tier 1 capital. For such purposes, MSRs and PCCRs each are included in Tier 1
  capital only up to the lesser of (i) 90% of their fair market value (which
  must be determined quarterly) and (ii) 100% of the remaining unamortized book
  value of such assets. The OCC has adopted substantially similar regulations.

       In addition, the Federal Reserve Board's minimum "leverage ratio" (the
  ratio of Tier 1 capital to quarterly average total assets) guidelines for bank
  holding companies provide for a minimum leverage ratio of 3% for bank holding
  companies that meet certain specified criteria, including that they have the
  highest regulatory rating. All other bank holding companies are required to
  maintain a leverage ratio of 3% plus an additional cushion of 1% to 2%. The
  guidelines also 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. Furthermore, the guidelines
  indicate that the Federal Reserve Board will continue to 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, less all intangibles, to total assets, less all
  intangibles. Each of Norwest's banking subsidiaries is also subject to capital
  requirements adopted by applicable regulatory agencies that are substantially
  similar to the foregoing. At June 30, 1996, Norwest's Tier 1 and total capital
  (the sum of Tier 1 and Tier 2 capital) to risk-adjusted assets ratios were
  8.53% and 10.49%, respectively, and Norwest's leverage ratio was 6.09%.
  Neither Norwest nor any subsidiary bank has been advised by the appropriate
  federal regulatory agency of any specific leverage ratio applicable to it.

       As a result of a federal law enacted in 1991 that required each federal
  banking agency to revise its risk-based capital standards to ensure that those
  standards take adequate account of interest rate risk, concentration of credit
  risk and the risks of nontraditional activities, each of the federal banking
  agencies has revised the risk-based capital guidelines described above to take
  account of concentration of credit risk and risk of nontraditional activities.
  In addition, the Federal Reserve Board, the FDIC and the OCC adopted a new
  rule that amends, effective September 1, 1995, the capital standards to
  include explicitly a bank's exposure to declines in the economic value of its
  capital due to changes in interest rates as a factor to be considered in
  evaluating a bank's interest rate exposure. Such agencies have issued for
  comment a joint policy statement that describes the process to be used to
  measure and assess the exposure of a bank's net economic value to changes in
  interest rates. These agencies have indicated that in the second step of this
  regulation process they intend to issue a proposed rule that would propose to
  establish an explicit minimum capital charge for interest rate risk based on
  the level of a bank's measured interest rate exposure. The agencies intend to
  implement the second step
                           
                                      49
<PAGE>
 
  after the agencies and the banking industry have had more experience with the
  proposed supervisory and measurement process. None of Norwest, Bancorp or the
  Bank believes that these recent proposals and revisions to the capital
  guidelines will materially impact its operations.

  FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991

       In December 1991, Congress enacted the Federal Deposit Insurance
  Corporation Improvement Act of 1991 ("FDICIA"), which substantially revised
  the bank regulatory and funding provisions of the Federal Deposit Insurance
  Act and makes revisions to several other federal banking statutes. Among other
  things, FDICIA requires the federal banking regulators to take "prompt
  corrective action" in respect of depository institutions insured by the
  Federal Deposit Insurance Corporation (the "FDIC") that do not meet minimum
  capital requirements. FDICIA establishes five capital tiers: "well
  capitalized," "adequately capitalized," "undercapitalized," "significantly
  undercapitalized" and "critically undercapitalized." Under applicable
  regulations, an FDIC-insured depository institution is defined to be well
  capitalized if it maintains a leverage ratio of at least 5%, a risk-adjusted
  Tier 1 capital ratio of at least 6% and a risk-adjusted total capital ratio of
  at least 10% and is not subject to a directive, order or written agreement to
  meet and maintain specific capital levels. An insured depository institution
  is defined to be adequately capitalized if it meets all of its minimum capital
  requirements as described above. An insured depository institution will be
  considered undercapitalized if it fails to meet any minimum required measure,
  significantly undercapitalized if it has a risk-adjusted total capital ratio
  of less than 6%, risk-adjusted Tier 1 capital ratio of less than 3% or a
  leverage ratio of less than 3% and critically undercapitalized if it fails to
  maintain a level of tangible equity equal to at least 2% of total assets. An
  insured depository institution may be deemed to be in a capitalization
  category that is lower than is indicated by its actual capital position if it
  receives an unsatisfactory examination rating.

       FDICIA generally prohibits a depository institution from making any
  capital distribution (including payment of a dividend) or paying any
  management fee to its holding company if the depository institution would
  thereafter be undercapitalized. Undercapitalized depository institutions are
  subject to a wide range of limitations on operations and activities, including
  growth limitations, and are required to submit a capital restoration plan. The
  federal banking agencies may not accept a capital plan without determining,
  among other things, that the plan is based on realistic assumptions and is
  likely to succeed in restoring the depository institution's capital. In
  addition, for a capital restoration plan to be acceptable, the depository
  institution's parent holding company must guarantee that the institution will
  comply with such capital restoration plan. The aggregate liability of the
  parent holding company is limited to the lesser of (i) an amount equal to 5%
  of the depository institution's total assets at the time it became
  undercapitalized and (ii) the amount which is necessary (or would have been
  necessary) to bring the institution into compliance with all capital standards
  applicable with respect to such institution as of the time it fails to comply
  with the plan. If a depository institution fails to submit an acceptable plan,
  it is treated as if it were significantly undercapitalized.

       Significantly undercapitalized depository institutions may be subject to
  a number of requirements and restrictions, including orders to sell sufficient
  voting stock to become adequately capitalized, requirements to reduce total
  assets and cessation of receipt of deposits from correspondent banks.
  Critically undercapitalized institutions are subject to the appointment of a
  receiver or conservator.

       FDICIA, as amended by the Reigle Community Development and Regulatory
  Improvement Act of 1994 enacted on August 22, 1994, directs that each federal
  banking agency prescribe standards, by regulation or guideline, for depository
  institutions relating to internal controls, information systems, internal
  audit systems, loan documentation, credit underwriting, interest rate
  exposure, asset growth, compensation, asset quality, earnings, stock
  valuation, and such other operational and managerial standards as the agency
  deems appropriate. The FDIC, in consultation with the other federal banking
  agencies, has adopted a final rule and guidelines with respect to internal and
  external audit procedures and internal controls in order to implement

                                      50
<PAGE>
 
  those provisions of FDICIA intended to facilitate the early identification of
  problems in financial management of depository institutions. On July 10, 1995,
  the federal banking agencies published the final rules implementing three of
  the safety and soundness standards required by FDICIA, including operational
  and managerial standards, asset quality and earnings standards, and
  compensation standards. The impact of such standards on Norwest has not yet
  been fully determined, but management does not believe it will be material.

       FDICIA also contains a variety of other provisions that may affect the
  operations of Norwest, including new reporting requirements, revised
  regulatory standards for real estate lending, "truth in savings" provisions,
  and the requirement that a depository institution give 90 days' notice to
  customers and regulatory authorities before closing any branch.

       Under other regulations promulgated under FDICIA a bank cannot accept
  brokered deposits (that is, deposits obtained through a person engaged in the
  business of placing deposits with insured depository institutions or with
  interest rates significantly higher than prevailing market rates) unless (i)
  it is well capitalized or (ii) it is adequately capitalized and receives a
  waiver from the FDIC. A bank that cannot receive brokered deposits also cannot
  offer "pass-through" insurance on certain employee benefit accounts, unless it
  provides certain notices to affected depositors. In addition, a bank that is
  adequately capitalized and that has not received a waiver from the FDIC may
  not pay an interest rate on any deposits in excess of 75 basis points over
  certain prevailing market rates. There are no such restrictions on a bank that
  is well capitalized.

  FDIC INSURANCE

       Each BIF member institution pays FDIC insurance premiums based on the
  institution's annual assessment rate assigned to it by the FDIC. The
  assessment rate is based on the institution's capitalization risk category and
  "supervisory subgroup." 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 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. Subgroup A institutions are
  financially sound institutions with few minor weaknesses; Subgroup B
  institutions are institutions that demonstrate weaknesses which, if not
  corrected, could result in significant deterioration; and Subgroup C
  institutions are institutions for which there is a substantial probability
  that the FDIC will suffer a loss in connection with the institution unless
  effective action is taken to correct the areas of weakness. The FDIC
  assessment rate ranges from zero to 27 cents per $100 of domestic deposits,
  with Subgroup A institutions assessed at a rate of zero and Subgroup C
  institutions assessed at a rate of 27 cents. The FDIC may increase or decrease
  the assessment rate schedule on a semiannual basis. An increase in the rate
  assessed one or more of Norwest's banking subsidiaries could have a material
  adverse effect on Norwest'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 with respect to one or more of Norwest's
  subsidiary depository institutions could have a material adverse effect on
  Norwest's earnings, depending on the collective size of the particular
  institutions involved.

       Deposits insured by the SAIF held by Norwest's bank subsidiaries as a
  result of savings association acquisitions by Norwest continue to be assessed
  at the applicable SAIF insurance premium rate. Current federal law provides
  that the SAIF assessment rate may not be less than 0.18% from January 1, 1994
  through December 31, 1997. After December 31, 1997, the SAIF assessment rate
  must be a rate determined by the FDIC to be appropriate to increase the SAIF's
  reserve ratio to 1.25% of insured deposits or such higher percentage as the
  FDIC determines to be appropriate, but the assessment rate may not be less
  than 0.15%. In order to mitigate the potential effects of a BIF/SAIF premium
  disparity, Congress recently proposed legislation that

                                      51
<PAGE>
 
  would, among other things, recapitalize the SAIF by imposing a special one-
  time assessment on SAIF deposits. The proposed legislation also contemplates
  the consolidation or merger of the BIF and the SAIF into one insurance fund
  after the SAIF is recapitalized. Management of Norwest does not anticipate
  that the impact of the proposed legislation will be material to Norwest;
  however, to provide for such a special assessment when and if imposed, Norwest
  has established a reserve of $23.5 million based on an estimated insurance
  premium rate of 66 cents per $100 of insured deposits, which reserve has been
  funded primarily by the refund of BIF insurance premiums.

  DEPOSITOR PREFERENCE

       Under the FDIA, claims of holders of domestic deposits and certain claims
  of administrative expenses and employee compensation against an FDIC-insured
  depository institution have priority over other general unsecured claims
  against the institution in the "liquidation or other resolution" of the
  institution by a receiver.

                         INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

The Board of Directors and Stockholders
Texas Bancorporation, Inc.:

We have audited the accompanying consolidated balance sheets of Texas
Bancorporation, Inc. (the Corporation) and its wholly-owned subsidiary, Texas
Bank of Odessa (the Bank) as of December 31, 1995 and 1994 and the related
consolidated statements of earnings, stockholders' equity and cash flows for
each of the years in the three-year period ended December 31, 1995. These
consolidated financial statements are the responsibility of the Corporation's
management. Our responsibility is to express an opinion on these 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 audits 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
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 financial position of Texas
Bancorporation, Inc. and subsidiary as of December 31, 1995 and 1994 and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1995 in conformity with generally accepted
accounting principles.

As discussed in note 1, the Corporation changed its method of accounting for
impaired loans to adopt the provisions of the Financial Accounting Standards
Board's SFAS No. 114, "Accounting by Creditors for Impairment of a Loan", as
amended by SFAS No. 118, "Accounting by Creditors for Impairment of a Loan-
Income Recognition and Disclosures", on January 1, 1995. The Corporation also
changed its method of accounting for investments to adopt the provisions of the
FASB's SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities", at January 1, 1994. The corporation also changed its method of
accounting for income taxes to adopt the provisions of the FASB's SFAS No. 109,
"Accounting for Income Taxes", at January 1, 1993.

(1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     -----------------------------------------------------------

     ORGANIZATION
     ------------

     The accompanying consolidated financial statements include the accounts
     of Texas Bancorporation, Inc. (the Corporation) and its wholly-owned
     subsidiary, Texas Bank of Odessa (the Bank). All significant intercompany
     accounts and transactions have been eliminated in consolidation.

     Business - The Bank provides a full range of banking services to individual
     and corporate customers through its branch banks located in Austin, Burnet,
     Buchanan Dam, Dripping Springs, Kingsland, Pflugerville and Odessa, Texas.
     The Bank is subject to competition from other financial institutions. The
     Bank is subject to the regulations of certain state and federal agencies
     and undergoes periodic examinations by those regulatory authorities.

     Basis of Financial Statement Presentation - The financial statements have
     been prepared in conformity 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 date of the balance sheet and revenues and expenses
     for the period. 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 and the valuation of other real estate. In connection with the
     determination of the allowances for loan losses and real estate owned,
     management obtains independent appraisals for significant properties.

     A substantial portion of the Bank's loans are secured by real estate in
     Central and West Texas. Accordingly, the ultimate collectibility of a
     substantial portion of the Bank's loan portfolio and the recovery of the
     carrying amount of real estate owned are susceptible to changes in market
     conditions in these areas of Texas.

(1)  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
     ----------------------------------------------------------------------

     ORGANIZATION, CONTINUED
     -----------------------

     Management believes that the allowances for losses on loans and real estate
     owned are adequate. While management uses available information to
     recognize losses on loans and real estate owned, future additions to the
     allowances may be necessary based on changes in economic conditions,
     particularly in Texas. In addition, various regulatory agencies, as an
     integral part of their examination process, periodically review the Bank's
     allowances for losses on loans and real estate owned. Such agencies may
     require the Bank to recognize additions to the allowances based on their
     judgments about information available to them at the time of their
     examination.

     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     ------------------------------------------

     The following is a description of the significant accounting policies:

     Investment Securities - In May 1993, the Financial Accounting Standards
     Board (FASB) issued Statement of Financial Accounting Standards No. 115,
     "Accounting for Certain Investments in Debt and Equity Securities".
     Statement 115 addresses the accounting and reporting for investments in
     debt and equity securities. Under Statement 115, those investments are to
     be classified in three categories and accounted for as follows:

     Classification                              Accounting

     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
     -----------------------------------------------------

     The Bank adopted Statement 115 on January 1, 1994. The Bank classified all
     of its securities as available for sale. The Bank's adoption of Statement
     115 initially resulted in an unrealized gain, net of related tax effects,
     of $88,977 being recorded as a separate component of stockholder's equity.
     As of December 31, 1995, there was a net unrealized loss of $117,230
     reflected in stockholders' equity.

     Cost of securities sold is determined by the specific identification
     method. Provisions for losses on investment securities are made when an
     other than temporary impairment is anticipated by management or known to
     exist, including losses on sales of securities prior to maturity.

     Mortgage-backed securities and collateralized mortgage obligations
     represent participating interests in pools of long-term first mortgage
     loans originated and serviced by the issuer of the securities. Premiums and
     discounts are amortized to income using the interest method over the
     remaining life to contractual maturity, adjusted for anticipated
     prepayments.

     Loans and Allowance for Possible Loan Losses - It is management's policy to
     charge off all known losses as they are specifically identified. In
     addition, provisions to the allowance for possible loan losses are based
     upon a continuing review of the loan portfolio, financial condition of the
     borrowers, current economic conditions and other pertinent factors.

     Management continually reviews the loan portfolio in order to identify
     loans which, with respect to principal and interest, have or may become
     collection problems. When a loan, in management's judgment, becomes
     doubtful as to the collection of accrued interest income, it is placed on
     non-accrual status. Interest payments received on non-accrual loans are
     recognized as income on a cash basis.

     Discounts on loans are accreted to income using a method which does not
     materially differ from the interest method over the estimated lives of the
     related loans. Unearned discount on installment loans are recognized during
     the terms of the loans in decreasing amounts by the sum-of-the-months'-
     digits method, which approximates the interest method.

                                                                     (Continued)

     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED
     -----------------------------------------------------

     Loan fees and certain direct loan origination costs are deferred, and the
     net fee or cost is recognized in income using the interest method over the
     contractual life of the loans, adjusted for actual prepayments. Commitment
     fees and costs relating to commitments whose likelihood of exercise is
     remote are recognized over the commitment period on a straight-line basis.
     If the commitment is subsequently exercised during the commitment period,
     the remaining unamortized commitment fee at the time of exercise is
     recognized over the life of the loan as an adjustment of yield. Cost is
     allocated to the portion of loans sold based on the relative fair value of
     the portion retained and the portion sold.

     In May 1993, FASB issued Statement of Financial Accounting Standards No.
     114, "Accounting by Creditors for Impairment of a Loan". Statement No. 114
     addresses the accounting by creditors for impairment of certain loans. It
     requires that impaired loans 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
     underlying collateral if the loan is collateral dependent. Statement No.
     118, issued October 1994, amended Statement No. 114 to allow a creditor to
     use existing methods to recognize interest income on impaired loans. The
     Corporation adopted the provisions of Statements 114 and 118 effective
     January 1, 1995. The Bank's prior method of determining impairment of loans
     did not differ materially from Statements 114 and 118.

     Other Real Estate - Real estate acquired by foreclosure is carried at fair
     value at the date of foreclosure. Prior to foreclosure, the value of the
     underlying loan is adjusted to the fair value of the real estate to be
     acquired through the allowance for loan losses, if necessary. After
     foreclosure, foreclosed assets are carried at the lower of fair value minus
     estimated selling costs or cost. Operating expenses of such properties, net
     of related income, and gains and losses on their disposition are included
     in other operating expenses.
                                                                     (Continued)

     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

     Bank Premises and Equipment - Bank premises and equipment are stated at
     cost less accumulated depreciation and amortization. Depreciation expense
     is computed principally on the straight-line method over the estimated
     useful lives of the assets. Leasehold improvements are amortized on the
     straight-line method over the shorter of the estimated useful lives of the
     improvements or the terms of the related leases.

     Federal Income Taxes - In February 1992, the Financial Accounting Standards
     Board issued Statement of Financial Accounting Standards No. 109,
     "Accounting for Income Taxes". Statement 109 requires a change from the
     deferred method of accounting for income taxes of APB Opinion 11 to the
     asset and liability method of accounting for income taxes. Under the asset
     and liability method of Statement 109, deferred tax assets and liabilities
     are recognized for the future tax consequences attributable to differences
     between the financial statement carrying amounts of existing assets and
     liabilities and their respective tax bases and operating loss and tax
     credit carryforwards. Deferred tax assets and liabilities are measured
     using enacted tax rates expected to apply to taxable income in the years in
     which those temporary differences are expected to be recovered or settled.
     Under Statement 109, the effect on deferred tax assets and liabilities of a
     change in tax rates is recognized in income in the period that includes the
     enactment date. The adoption of Statement 109 in 1993 resulted in a
     cumulative effect adjustment for the change in method of accounting for
     income taxes of an approximate $170,000 expense.

     Earnings Per Share - Earnings per share is based on dividing net income by
     the weighted average number of shares of common stock outstanding during
     the period.

      Certain assets and liabilities of two failed banks in the Austin area were
      acquired from the FDIC. The Bank has adopted a cost recovery method of
      income recognition related to the discount on acquired loans for which
      collectibility of the contractual loan amount is in question and is
      recognizing the discount to income using the interest method over the
      estimated life of the loan when collectibility is probable. Charge-offs in
      excess of the discount are then charged to the allowance for loan loss.
      The remaining discount allocated to loans at December 31, 1995 and 1994 is
      $937,000 and $1,194,000, respectively. The remaining purchase discount is
      from other purchased loans. The amount of discount recognized as interest
      income in 1995, 1994 and 1993 was approximately $288,125, $596,000, and
      $973,000, respectively. Additional purchase discounts resulted from
      purchases of other loans acquired by the Bank.

      At December 31, 1995 and 1994, the Bank was servicing approximately
      $29,900,000 and $25,333,000, respectively, of principal balance of loans
      which were sold with Small Business Administration guarantees.

                                                                     (Continued)

(3)   LOANS, CONTINUED
      ----------------

      The recorded investment in loans which an impairment has been recognized
      consists of loans which income is recognized on the cash basis (nonaccrual
      loans) was $150,000 and $166,000 at December 31, 1995 and 1994,
      respectively. The related allowance for loan losses on these loans is
      $30,000 at December 31, 1995. If interest on these loans had been accrued,
      income would have been increased by approximately $30,000 in 1995, $12,000
      in 1994, and $9,000 in 1993. The average balances of impaired loans was
      approximately $150,000 during 1995. Interest income recognized on impaired
      loans during 1995 was $5,000. At December 31, 1995, there were no
      commitments to lend additional funds to borrowers whose loans are
      classified nonaccrual.

      Letters of credit and commitments to fund loans totaling $8,300,000 were
      outstanding at December 31, 1995. If the counterparties to the
      aforementioned off-balance sheet commit-ments failed to perform, the Bank
      could suffer losses. However, the aforementioned off-balance sheet
      commitments are subject to the Bank's internal loan policies and are
      generally secured by deposits in the Bank, real property or equipment and
      inventory.

      Loans to officers and directors of the Bank totaled approximately
      $2,374,000 at December 31, 1995 and were approximately $3,394,000 at
      December 31, 1994. These loans were made at substantially the same terms
      available to other customers of the Bank.

      Transactions in the allowance for possible loan losses were as follows:

      believes that it is more likely than not it will be able to realize its
      remaining deferred tax assets through future earnings or reversal of
      temporary differences generating deferred tax liabilities.

      guidelines for state banks utilizing risk-based capital and leverage
      capital frameworks. At December 31, 1995, the Bank was required to have a
      minimum ratio of Tier 1 capital to total risk-adjusted assets of not less
      than 4%, a ratio of combined Tier 1 and Tier 2 capital to total risk-
      adjusted assets of not less than 8%, and a leverage ratio of not less than
      4%. The State Banking Regulator (State) requires a leverage of capital
      ratio of 6%. Tier 1 capital includes only common stockholders' equity,
      common stock warrants and perpetual preferred stock. Tier 2 capital
      includes other capital elements such as limited life preferred stock,
      subordinated debt and the allowance for loan losses. The allowance for
      loan losses may be included only to the extent of 1.25% of risk-adjusted
      assets. Any excess of the allowance for loan losses over these limits is
      treated as a reduction in the total risk-based asset amount in the risk-
      based capital calculation. The leverage ratio is the ratio of Tier 1
      capital to total assets reduced for any intangible assets. At December 31,
      1995, the Bank had a Tier 1 capital ratio to risk adjusted assets ratio of
      9.92% a combined Tier 1 and Tier 2 capital to total risk adjusted assets
      ratio of 10.68% and a leverage ratio of 8.36% based on regulatory capital
      guidelines.

      As a state bank, the Bank is subject to dividend restrictions as set forth
      by the Federal Deposit Insurance Corporation.

      The Corporation declared and paid a $500,000 dividend in 1995, declared
      and paid a $764,400 dividend in 1993 and declared a $1,000,000 dividend in
      1993 which was paid to shareholders' on January 4, 1994.

(13)  BANK ACQUISITION
      ----------------

      Texas Bancorporation, Inc. acquired the outstanding common stock of Lake
      Buchanan State Bank, a state chartered bank in Burnet, Texas (the Acquired
      Bank). The Acquired Bank was merged into the Bank. This acquisition and
      merger was consummated in April 1995.

      The acquisition of Lake Buchanan State Bank has been recorded under the
      purchase method of accounting. Accordingly, all assets acquired and
      liabilities assumed have been recorded at their fair value as of the date
      of acquisition.

                                                                     (Continued)

      Fair value estimates, methods, and assumptions are set forth below for the
      Bank's financial instruments.

      Cash and Cash Equivalents
      -------------------------

      The carrying amounts for cash and cash equivalents approximate fair value
      because they mature in less than 90 days and do not present unanticipated
      credit concerns.

(14)  FAIR VALUE OF FINANCIAL INSTRUMENTS, CONTINUED
      ----------------------------------------------

      Investments and Mortgage-Backed Securities
      ------------------------------------------

      The fair value of longer-term investments and mortgage-backed securities
      is estimated based on bid prices published in financial newspapers or bid
      quotations received from securities dealers.

      Loans
      -----

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

      The fair value of performing 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.

      Fair value for significant nonperforming loans is based on recent external
      appraisals. If appraisals are not available, estimated cash flows are
      discounted using a rate commensurate with the risk associated with the
      estimated cash flows. Assumptions regarding credit risk, cash flows, and
      discount rates are judgmentally determined using available market informa-
      tion and specific borrower information.

      Average maturity represents the expected average cash flow period, which
      in some instances is different than the stated maturity.

      Management has made estimates of fair value discount rates that it
      believes to be reasonable. However, because there is no market for many of
      these financial instruments, management has no basis to determine whether
      the fair value presented above would be indicative of the value negotiated
      in an actual sale.

                                                                     (Continued)

- --------------------------------------------------------------------------------
(14) FAIR VALUE OF FINANCIAL INSTRUMENTS, CONTINUED
     ----------------------------------------------

     Deposit Liabilities
     -------------------

     The fair value of deposits with no stated maturity, such a non-interest
     bearing demand deposits, savings, and NOW and money market accounts, is
     equal to the amounts payable on demand as of December 31, 1995. The fair
     value of certificates of deposit and individual retirement accounts are
     based on the discounted value of contractual cash flows. The discount rate
     is estimated using the rates currently offered for deposits of similar
     remaining maturities.

     The fair value estimates do not include the benefit that results from the
     low-cost funding provided by the deposit liabilities compared to the cost
     of borrowing funds in the market.

     Subordinated Debentures
     -----------------------

     The fair value of subordinated debentures equal to the stated amount
     because the debentures adjust to estimated market rates on a semiannual
     basis.

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

     The fair value of commitments to extend credit is estimated using the fees
     currently charged to enter into similar agreements, taking into account the
     remaining terms of the agreements and the present creditworthiness of the
     counterparties. For fixed rate loan commitments, fair value also considers
     the difference between current levels of interest rates and the committed
     rates. The fair value of financial guarantees written and letters of credit
     is based on fees currently charged for similar agreements or on the
     estimated cost to terminate them or otherwise settle the obligations with
     the counterparties. The carrying amount and fair value of the
     aforementioned off-balance sheet items is not material.

                                                                     (Continued)

      Limitations
      -----------

      Fair value estimates are made at specific point in time, based on relevant
      market information and information about the financial instrument. These
      estimates do not reflect any premium or discount that could result from
      offering for sale at one time the Bank's entire holdings of a particular
      financial instrument. Because no market exists for a significant portion
      of the Bank'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, bank premises and equipment, and
      goodwill. 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 aforementioned
      estimates.
      
(15)  DIRECTORS' BONUS EXPENSE
      ------------------------

      In 1993, the Corporation paid a $647,550 directors' bonus for all
      directors of the Bank for their involvement in Board of Directors'
      meetings and Board committees since 1986. The Corporation also paid
      directors' fees of $72,000 for all directors of the Corporation for 1993.
      The Corporation and Bank's directors' fees have been included in salaries
      and employees benefits in the 1994 and 1995 consolidated statements of
      earnings.

                            PLAN OF REORGANIZATION



     AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as of
the 3rd day of June, 1996, by and between TEXAS BANCORPORATION, INC.
("Bancorp"), a Texas corporation, and NORWEST CORPORATION ("Norwest"), a
Delaware corporation.

     WHEREAS, the parties hereto desire to effect a reorganization whereby a
wholly-owned subsidiary of Norwest will merge with and into Bancorp (the
"Merger") pursuant to an agreement and plan of merger (the "Merger Agreement")
in substantially the form attached hereto as Exhibit A, which provides, among
other things, for the conversion and exchange of the shares of Common Stock of
Bancorp of the par value of $0.01 per share ("Bancorp Common Stock") outstanding
immediately prior to the time the Merger becomes effective in accordance with
the provisions of the Merger Agreement into shares of voting Common Stock of
Norwest of the par value of $1-2/3 per share ("Norwest Common Stock"),

     NOW, THEREFORE, to effect such reorganization and in consideration of the
premises and the mutual covenants and agreements contained herein, the parties
hereto do hereby represent, warrant, covenant and agree as follows:

   1.  BASIC PLAN OF REORGANIZATION

   (a)  Merger. Subject to the terms and conditions contained herein, a wholly-
owned subsidiary of Norwest (the "Merger Co.") will be merged by statutory
merger with and into Bancorp pursuant to the Merger Agreement, with Bancorp as
the surviving corporation, in which merger each share of Bancorp 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 converted into and exchanged for the number of
shares of Norwest Common Stock determined by dividing 762,500 by the number of
shares of Bancorp Common Stock then outstanding.

     (b)  Norwest Common Stock Adjustments. If, between the date hereof and the
Effective Time of the Merger, shares of Norwest 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 Norwest Common Stock into which a share of Bancorp Common Stock shall
be converted pursuant to subparagraph (a), above, will be appropriately and
proportionately adjusted so that the number of such shares of
<PAGE>
 
Norwest Common Stock into which a share of Bancorp Common Stock shall be
converted will equal the number of shares of Norwest Common Stock which holders
of shares of Bancorp 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 Norwest 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
Norwest Common Stock as reported by the consolidated tape of the New York Stock
Exchange for each of the five (5) 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, the expiration of all required waiting periods and the
meeting of shareholders held to approve the Merger. 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. Odessa, 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 of Merger Co. shall cease and Merger Co. will be merged
with and into Bancorp 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 Norwest, Norwest Center, Sixth and Marquette, Minneapolis, Minnesota.

     2.  REPRESENTATIONS AND WARRANTIES OF BANCORP. Bancorp represents and
warrants to Norwest as follows:

     (a)  Organization and Authority. Bancorp 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 Bancorp and the Bancorp Subsidiaries 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. Bancorp is registered as a bank
holding company with the Federal Reserve Board under the Bank Holding Company
Act

                                      -2-
<PAGE>
 
of 1956, as amended (the "BHC Act"). Bancorp has furnished Norwest true and
correct copies of its articles of incorporation and by-laws, as amended.

     (b)  Bancorp's Subsidiaries. Schedule 2(b) sets forth a complete and
correct list of all of Bancorp's subsidiaries as of the date hereof
(individually a "Bancorp Subsidiary" and collectively the "Bancorp
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
Bancorp. No equity security of any Bancorp 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 Bancorp 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 the Texas Business
Corporation Act and the Texas Banking Act, all of such shares so owned by

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

Subsidiary and no dividends or other distributions have been declared, set
aside, made or paid to the shareholders of Bancorp.

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 Bancorp and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by the Board of
Directors of Bancorp. Subject to such approvals of shareholders and of

     Except as set forth on Schedule 2(d), neither the execution, delivery and
performance by Bancorp of this Agreement or the Merger Agreement, nor the
consummation of the transactions contemplated hereby and thereby, nor compliance
by Bancorp 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 Bancorp or any Bancorp 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 Bancorp or
any Bancorp Subsidiary is a party or by which it may be bound, or to which
Bancorp or any Bancorp Subsidiary or any of the properties or assets of Bancorp
or any Bancorp 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 Bancorp, violate any judgment, ruling, order, writ, injunction,
decree, statute, rule or regulation applicable to Bancorp or any Bancorp
Subsidiary or any of their respective properties or assets.

     Other than in connection or in compliance with the provisions of the
Securities Act of 1933 and the rules and regulations thereunder (the "Securities
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

necessary for the consummation by Bancorp of the transactions contemplated by

consolidated

                                      -4-

ended December 31, 1995, together with the notes thereto, certified by KPMG Peat
Marwick LLP, and the unaudited consolidated statements of financial condition of
Bancorp and Bancorp's Subsidiaries as of March 31, 1996 and the related
unaudited consolidated statements of income, shareholders' equity and cash flows
for the three (3) months then ended (collectively, the "Bancorp Financial
Statements"), have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis and present fairly (subject,
in the case of financial statements for interim periods, to normal recurring
adjustments) the consolidated financial position of Bancorp and Bancorp's
Subsidiaries at the dates and the consolidated results of operations and cash
flows of Bancorp and Bancorp's Subsidiaries for the periods stated therein.

     (f)  Reports. Since December 31, 1990, Bancorp and each Bancorp Subsidiary
has filed all reports, registrations and statements, together with any required
amendments thereto, that it was required to file, if any, with (i) the
Securities and Exchange Commission (the "SEC"), including, but not limited to,
Forms 10-K, Forms 10-Q and proxy statements, (ii) the Federal Reserve Board,
(iii) the Federal Deposit Insurance Corporation (the "FDIC"), (iv) the United
States Comptroller of the Currency (the "Comptroller") and (v) any applicable
state securities or banking authorities. All such reports and statements filed
with any such regulatory body or authority are collectively referred to herein
as the "Bancorp Reports". As of their respective dates, the Bancorp Reports, as
amended, complied in all 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 stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Copies of all the Bancorp Reports have been made available to
Norwest by Bancorp.

     (g)  Properties and Leases. Except as may be reflected in the Bancorp
Financial Statements and except for any lien for current taxes not yet
delinquent, Bancorp and each Bancorp Subsidiary have good title free and clear
of any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Bancorp's
consolidated balance sheet as of March 31, 1996 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 Bancorp or any
Bancorp Subsidiary pursuant to which Bancorp or such Bancorp 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 Bancorp or
such Bancorp Subsidiary or any event which, with notice or lapse of time or
both, would constitute such a material default. Substantially all Bancorp's and
each Bancorp Subsidiary's buildings and equipment in regular use have been well
maintained and are in good and serviceable condition, reasonable wear and tear
excepted.

                                      -5-

     (h)  Taxes. Except as set forth in Schedule 2(h), each of Bancorp and the
Bancorp Subsidiaries has filed all federal, state, county, local and foreign tax
returns, including information returns, required to be filed by it, and paid 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 tax returns of
Bancorp and the Bancorp Subsidiaries for the fiscal year ended December 31,
1992, and for all fiscal years prior thereto, are for the purposes of 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 Bancorp nor any
Bancorp Subsidiary is a party to any pending action or proceeding, nor to
Bancorp's knowledge is any such action or proceeding threatened by any
governmental authority, for the assessment or collection of taxes, interest,
penalties, assessments or deficiencies and (ii) no issue has been raised by any
federal, state, local or foreign taxing authority in connection with an audit or
examination of the tax returns, business or properties of Bancorp or any Bancorp
Subsidiary which has not been settled, resolved and fully satisfied. Each of
Bancorp and the Bancorp Subsidiaries has paid all taxes owed or which it is
required to withhold from amounts owing to employees, creditors or other third
parties. The consolidated balance sheet as of March 31, 1996, referred to in
paragraph 2(e) hereof, includes adequate provision for all accrued but unpaid
federal, state, county, local and foreign taxes, interest, penalties,
assessments or deficiencies of Bancorp and the Bancorp Subsidiaries with respect
to all periods through the date thereof.

     (i)  Absence of Certain Changes. Since December 31, 1995 there has been no
change in the business, financial condition or results of operations of Bancorp
or any Bancorp 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 Bancorp and the Bancorp Subsidiaries taken as a whole.

     (j)  Commitments and Contracts. Except as set forth on Schedule 2(j),
neither Bancorp nor any Bancorp Subsidiary is a party or subject to any of the
following (whether written or oral, express or implied):

          (i)  any employment contract or understanding (including any
     understandings or obligations with respect to severance or termination pay
     liabilities or fringe benefits) with any present or former officer,
     director, employee or consultant (other than those which are terminable at
     will by Bancorp or such Bancorp Subsidiary);

          (ii)  any plan, contract or understanding providing for any bonus,
     pension, option, deferred compensation, retirement payment, profit sharing
     or similar arrangement with respect to any present or former officer,
     director, employee or consultant;

          (iii)  any labor contract or agreement with any labor union;

                                      -6-
<PAGE>
 
          (iv)  any contract not made in the ordinary course of business
     containing covenants which limit the ability of Bancorp or any Bancorp
     Subsidiary to compete in any line of business or with any person or which
     involve any restriction of the geographical area in which, or method by
     which, Bancorp or any Bancorp 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 or
     more; or

          (vii)  any agreement or commitment with respect to the Community
     Reinvestment Act with any state or federal bank regulatory authority or any
     other party; or

          (viii)  any current or past agreement, contract or understanding with
     any current or former director, officer, employee, consultant, financial
     adviser, broker, dealer, or agent providing for any rights of
     indemnification in favor of such person or entity.

     (k)  Litigation and Other Proceedings. Bancorp has furnished Norwest copies
of (i) all attorney responses to the request of the independent auditors for
Bancorp with respect to loss contingencies as of December 31, 1995 in connection
with the Bancorp Financial Statements, and (ii) a written list of legal and
regulatory proceedings filed against Bancorp or any Bancorp Subsidiary since
said date. Neither Bancorp nor any Bancorp Subsidiary is a party to any pending
or, to the best knowledge of Bancorp, threatened, claim, action, suit,
investigation or proceeding, or is subject to any order, judgment or decree,
except for matters which, in the 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 Bancorp and the Bancorp Subsidiaries taken
as a whole.

     (l)  Insurance. Bancorp and each Bancorp Subsidiary is presently insured,
and during each of the past five calendar years (or during such lesser period of
time as Bancorp has owned such Bancorp Subsidiary) has 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. Bancorp and each Bancorp Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or

                                      -7-
<PAGE>
 
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 conducted and
that are material to the business of Bancorp or such Bancorp Subsidiary; all
such permits, licenses, certificates of authority, orders and approvals are in
full force and effect and, to the best knowledge of Bancorp, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current. The conduct by Bancorp and each Bancorp
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 Bancorp nor any Bancorp 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 Bancorp or any Bancorp Subsidiary
which reasonably could be expected to have a material adverse effect on the
business or properties of Bancorp and the Bancorp Subsidiaries taken as a whole.

     (n)  Labor. No work stoppage involving Bancorp or any Bancorp Subsidiary is
pending or, to the best knowledge of Bancorp, threatened. Neither Bancorp nor
any Bancorp Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding which could
materially and adversely affect the business of Bancorp or such Bancorp
Subsidiary. Employees of Bancorp and the Bancorp Subsidiaries are not
represented by any labor union nor are any collective bargaining agreements
otherwise in effect with respect to such employees.

     (o)  Material Interests of Certain Persons. Except as set forth on Schedule
2(o), to the best knowledge of Bancorp no officer or director of Bancorp or any
Bancorp 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 Bancorp or any Bancorp Subsidiary.

     Schedule 2(o) sets forth a correct and complete list of any loan from
Bancorp or any Bancorp Subsidiary to any present officer, director, employee or
any associate or related interest of any such person which was required under
Regulation O of the Federal Reserve Board to be approved by or reported to
Bancorp's or such Bancorp Subsidiary's Board of Directors.

     (p)  Bancorp Benefit Plans.

          (i)  The only "employee benefit plans" within the meaning of Section
     3(3) of the Employee Retirement Income Security Act of 1974, as amended
     ("ERISA"), for which Bancorp or any Bancorp Subsidiary acts as the plan
     sponsor as defined in ERISA Section 3(16)(B), and with respect to which any
     material liability under ERISA or otherwise exists or may be incurred by
     Bancorp or any Bancorp

                                      -8-
<PAGE>
 
     Subsidiary are those set forth on Schedule 2(p) (the "Plans"). No Plan is a
     "multi-employer plan" within the meaning of Section 3(37) of ERISA.

          (ii)  Each Plan is and has been in all material respects operated and
     administered in accordance with its provisions and applicable law. Except
     as set forth on Schedule 2(p), Bancorp or the Bancorp subsidiaries have
     received favorable determination letters from the Internal Revenue Service
     under the provisions of the Tax Equity and Fiscal Responsibility Act
     ("TEFRA"), the Deficit Reduction Act ("DEFRA") and the Retirement Equity
     Act ("REA") for each of the Plans to which the qualification requirements
     of Section 401(a) of the Internal Revenue Code of 1986, as amended (the
     "Code"), apply. Bancorp knows of no reason that any Plan which is subject
     to the qualification provisions of Section 401(a) of the Code is not
     "qualified" within the meaning of Section 401(a) of the Code and that each
     related trust is not exempt from taxation under Section 501(a) of the Code.

          (iii)  The present value of all benefits vested and all benefits
     accrued under each Plan which is subject to Title IV of ERISA did not, in
     each case, as determined for purposes of reporting on Schedule B to the
     Annual Report on Form 5500 of each such Plan as of the end of the most
     recent Plan year exceed the value of the assets of the Plan allocable to
     such vested or accrued benefits.

          (iv)  Except as disclosed in Schedule 2(p), and to the best knowledge
     of Bancorp, no Plan, if any, or any trust created thereunder, nor any
     trustee, fiduciary or administrator thereof, has engaged in a "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA or violated any of the fiduciary standards under Part
     4 of Title I of ERISA which could subject, to the best knowledge of
     Bancorp, such Plan or trust, or any trustee, fiduciary or administrator
     thereof, or any party dealing with any such Plan or trust, to the tax or
     penalty on prohibited transactions imposed by said Section 4975 or would
     result in material liability to Bancorp and the Bancorp Subsidiaries taken
     as a whole.

          (v)  No Plan, if any, which is subject to Title IV of ERISA or any
     trust created thereunder has been terminated, nor have there been any
     "reportable events" as that term is defined in Section 4043 of ERISA, with
     respect to any Plan, other than those events which may result from the
     transactions contemplated by this Agreement and the Merger Agreement.

          (vi)  No Plan, if any, or any trust created thereunder has incurred
     any "accumulated funding deficiency", as such term is defined in Section
     412 of the Code (whether or not waived), since the effective date of ERISA.

          (vii)  Except as disclosed in Schedule 2(p), neither the execution and
     delivery of this Agreement and the Merger Agreement nor the consummation of
     the transactions contemplated hereby and thereby will (i) result in any
     material payment (including, without limitation, severance, unemployment
     compensation,

                                      -9-
<PAGE>
 
     golden parachute or otherwise) becoming due to any director or employee or
     former employee of Bancorp or any Bancorp Subsidiary under any Plan or
     otherwise, (ii) materially increase any benefits otherwise payable under
     any Plan or (iii) result in the acceleration of the time of payment or
     vesting of any such benefits to any material extent.

     (q)  Proxy Statement, etc. None of the information regarding Bancorp and
the Bancorp Subsidiaries supplied or to be supplied by Bancorp for inclusion in
(i) a Registration Statement on Form S-4 to be filed with the SEC by Norwest for
the purpose of registering the shares of Norwest Common Stock to be exchanged
for shares of Bancorp Common Stock pursuant to the provisions of the Merger
Agreement (the "Registration Statement"), (ii) the proxy statement to be mailed
to Bancorp's shareholders in connection with the meeting to be called to
consider the Merger (the "Proxy Statement") and (iii) any other documents to be
filed with the SEC or any regulatory authority in connection with the
transactions contemplated hereby or by the Merger Agreement will, at the
respective times such documents are filed with the SEC or any regulatory
authority and, in the case of the Registration Statement, when it becomes
effective and, with respect to the Proxy Statement, when mailed, be false or
misleading with respect to any material fact, or omit to state any material fact
necessary in order to make the statements therein not misleading or, in the case
of the Proxy Statement or any amendment thereof or supplement thereto, at the
time of the meeting of shareholders referred to in paragraph 4(c), be false or
misleading with respect to any material fact, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to
the solicitation of any proxy for such meeting. All documents which Bancorp and
the Bancorp Subsidiaries are responsible for filing with the SEC and any other
regulatory authority in connection with the Merger will comply as to form in all
material respects with the provisions of applicable law.

     (r)  Registration Obligations. Neither Bancorp nor any Bancorp Subsidiary
is under any obligation, contingent or otherwise, which will survive the Merger
by reason of any agreement to register any of its securities under the
Securities Act.

     (s)  Brokers and Finders. Neither Bancorp nor any Bancorp Subsidiary nor
any of their respective officers, directors or employees has employed any broker
or finder or incurred any liability for any financial advisory fees, brokerage
fees, commissions or finder's fees, and no broker or finder has acted directly
or indirectly for Bancorp or any Bancorp Subsidiary in connection with this
Agreement and the Merger Agreement or the transactions contemplated hereby and
thereby.

     (t)  Fiduciary Activities. Neither Bancorp nor any Bancorp subsidiary has
ever had any accounts for which it has acted as a fiduciary including but not
limited to accounts for which it has served as trustee, agent, custodian,
personal representative, guardian, conservator or investment advisor.

     (u)  No Defaults. Neither Bancorp nor any Bancorp Subsidiary is in default,
nor has any event occurred which, with the passage of time or the giving of
notice, or both,

                                     -10-
<PAGE>
 
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 Bancorp and the Bancorp Subsidiaries, taken as a whole. To the best of
Bancorp's knowledge, all parties with whom Bancorp or any Bancorp Subsidiary has
material leases, agreements or contracts or who owe to Bancorp or any Bancorp
Subsidiary material obligations other than with respect to those arising in the
ordinary course of the banking business of the Bancorp Subsidiaries are in
compliance therewith in all material respects.

     (v)  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 of, on Bancorp or any Bancorp Subsidiary, 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, the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, pending or to the best of Bancorp's
knowledge, threatened against Bancorp or any Bancorp Subsidiary the result of
which has had or could reasonably be expected to have a material adverse effect
upon Bancorp and Bancorp's Subsidiaries taken as a whole; to the best of
Bancorp's knowledge there is no reasonable basis for any such proceeding, claim
or action; and to the best of Bancorp's knowledge neither Bancorp nor any
Bancorp 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. Bancorp has provided Norwest with copies of all
environmental assessments, reports, studies and other related information in its
possession with respect to each bank facility and each non-residential OREO
property.

     3.  REPRESENTATIONS AND WARRANTIES OF NORWEST.  Norwest represents and

     (a)  Organization and Authority. Norwest is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware,

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 Norwest and its subsidiaries 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. Norwest is registered as a bank
holding company with the Federal Reserve Board under the BHC Act. Norwest has

and collectively the "Norwest Subsidiaries"), all shares of the outstanding
capital stock of each of which, except as set forth in Schedule 3(b), are owned
directly or indirectly by Norwest. No equity security of any Norwest Subsidiary
is or may be required to be issued to any person

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 Norwest Subsidiary is bound to issue additional shares
of its capital stock, or options, warrants or rights to purchase or acquire any
additional shares of its capital stock. Subject to 12 U.S.C. (S) 55 (1982), all
of such shares so owned by Norwest 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 Norwest Subsidiary is a corporation 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

outstanding; and (iii) 500,000,000 shares of Common Stock, $1-2/3 par value, of
which as of the close of business on December 31, 1995, 352,760,457 shares were
outstanding and 5,571,696 shares were held in the treasury. All of the
outstanding shares of capital stock of Norwest have been duly and validly
authorized and issued and are fully paid and nonassessable.

     (d)  Authorization. Norwest has the corporate power and authority to enter
into this Agreement and to carry out its obligations hereunder. The execution,
delivery and performance of this Agreement by Norwest and the consummation of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of Norwest. No approval or consent by the stockholders of Norwest is
necessary for the execution and delivery of this Agreement and the Merger
Agreement and the consummation of the transactions contemplated hereby and
thereby. Subject to such approvals of government agencies and other governing
boards having regulatory authority over Norwest as may be required by statute or
regulation, this Agreement is a valid and binding obligation of Norwest
enforceable against Norwest in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the rights of creditors and
contracting parties generally and except as enforceability may be subject to
general principles of equity.

     Neither the execution, delivery and performance by Norwest of this
Agreement or the Merger Agreement, nor the consummation of the transactions
contemplated hereby and thereby, nor compliance by Norwest 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,

                                     -12-
<PAGE>
 
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 Norwest or any Norwest Subsidiary under any of the
terms, conditions or provisions of (x) its certificate 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 Norwest or
any Norwest Subsidiary is a party or by which it may be bound, or to which
Norwest or any Norwest Subsidiary or any of the properties or assets of Norwest
or any Norwest 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 Norwest, violate any judgment, ruling, order, writ, injunction,
decree, statute, rule or regulation applicable to Norwest or any Norwest
Subsidiary or any of their respective properties or assets.

     Other than in connection with or in compliance with the provisions of the
Securities Act, the Exchange Act, the securities or blue sky laws of the various
states or filings, consents, reviews, authorizations, approvals or exemptions
required under the BHC Act, Texas Banking Act or the HSR Act, and filings
required to effect the Merger under Texas law, no notice to, filing with,
exemption or review by, or authorization, consent or approval of, any public
body or authority is necessary for the consummation by Norwest of the
transactions contemplated by this Agreement and the Merger Agreement.

     (e)  Norwest Financial Statements. The consolidated balance sheets of
Norwest and Norwest's subsidiaries as of December 31, 1995 and 1994 and related
consolidated statements of income, stockholders' equity and cash flows for the
three years ended December 31, 1995, together with the notes thereto, certified
by KPMG Peat Marwick LLP and included in Norwest's Annual Report on Form 10-K
for the fiscal year ended December 31, 1995 (the "Norwest 10-K") as filed with
the SEC, and the unaudited consolidated balance sheets of Norwest and its
subsidiaries as of March 31, 1996 and the related unaudited consolidated
statements of income and cash flows for the three (3) months then ended included
in Norwest's Quarterly Report on Form 10-Q for the fiscal quarter ended March
31, 1996, as filed with the SEC (collectively, the "Norwest Financial
Statements"), have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis and present fairly (subject,
in the case of financial statements for interim periods, to normal recurring
adjustments) the consolidated financial position of Norwest and its subsidiaries
at the dates and the consolidated results of operations, changes in financial
position and cash flows of Norwest and its subsidiaries for the periods stated
therein.

     (f)  Reports. Since December 31, 1990, Norwest and each Norwest Subsidiary
has filed all reports, registrations and statements, together with any required
amendments thereto, that it was required to file with (i) the SEC, including,
but not limited to, Forms 10-K, Forms 10-Q and proxy statements, (ii) the
Federal Reserve Board, (iii) the FDIC, (iv) the Comptroller and (v) any
applicable state securities or banking authorities. All such reports and
statements filed with any such regulatory body or authority are collectively
referred to herein as the "Norwest Reports". As of their respective dates, the
Norwest Reports complied in all material respects with all the rules and
regulations promulgated by

                                     -13-
<PAGE>
 
the SEC, the Federal Reserve Board, the FDIC, the Comptroller and any 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 stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

     (g)  Properties and Leases. Except as may be reflected in the Norwest
Financial Statements and except for any lien for current taxes not yet
delinquent, Norwest and each Norwest Subsidiary has good title free and clear of
any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Norwest's
consolidated balance sheet as of March 31, 1996 included in Norwest's Quarterly
Report on Form 10-Q for the period then ended, and all real and personal
property acquired since such date, except such real and personal property has
been disposed of in the ordinary course of business. All leases of real property
and all other leases material to Norwest or any Norwest Subsidiary pursuant to
which Norwest or such Norwest Subsidiary, as lessee, leases real or personal
property, are valid and effective in accordance with their respective terms, and
there is not, under any such lease, any material existing default by Norwest or
such Norwest Subsidiary or any event which, with notice or lapse of time or
both, would constitute such a material default. Substantially all Norwest's and
each Norwest 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 Norwest and the Norwest Subsidiaries has filed all
material federal, state, county, local and foreign tax returns, including
information returns, required to be filed by it, and paid or made adequate
provision for the payment of 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 tax returns of Norwest and the Norwest Subsidiaries for the
fiscal year ended December 31, 1979, and for all fiscal years prior thereto, are
for the purposes of 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 3(h), (i) neither
Norwest nor any Norwest Subsidiary is a party to any pending action or
proceeding, nor to Norwest's knowledge is any such action or proceeding
threatened by any governmental authority, for the assessment or collection of
taxes, interest, penalties, assessments or deficiencies which could reasonably
be expected to have any material adverse effect on Norwest and its subsidiaries
taken as a whole, and (ii) no issue has been raised by any federal, state, local
or foreign taxing authority in connection with an audit or examination of the
tax returns, business or properties of Norwest or any Norwest Subsidiary which
has not been settled, resolved and fully satisfied, or adequately reserved for.
Each of Norwest and the Norwest Subsidiaries has paid all taxes owed or which it
is required to withhold from amounts owing to employees, creditors or other
third parties.

                                     -14-
<PAGE>
 
     (i)  Absence of Certain Changes. Since December 31, 1995, there has been no
change in the business, financial condition or results of operations of Norwest
or any Norwest 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 Norwest and its subsidiaries taken as a whole.

     (j)  Commitments and Contracts. Except as set forth on Schedule 3(j), as of
May 1, 1996 neither Norwest nor any Norwest Subsidiary is a party or subject to
any of the following (whether written or oral, express or implied):

          (i)  any labor contract or agreement with any labor union;

          (ii)  any contract not made in the ordinary course of business
     containing covenants which materially limit the ability of Norwest or any
     Norwest Subsidiary to compete in any line of business or with any person or
     which involve any material restriction of the geographical area in which,
     or method by which, Norwest or any Norwest Subsidiary may carry on its
     business (other than as may be required by law or applicable regulatory
     authorities);

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

     (k)  Litigation and Other Proceedings. Neither Norwest nor any Norwest
Subsidiary is a party to any pending or, to the best knowledge of Norwest,
threatened, claim, action, suit, investigation or proceeding, or is subject to
any order, judgment or decree, except for matters which, in the 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 Norwest and its
subsidiaries taken as a whole.

     (l)  Insurance. Norwest and each Norwest Subsidiary is presently insured or
self insured, and during each of the past five calendar years (or during such
lesser period of time as Norwest has owned such Norwest Subsidiary) has been
insured or self-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. Norwest and each Norwest Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has 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 or assets and to carry on its business as presently
conducted and that are material to the business of Norwest or such Subsidiary;
all such permits, licenses, certificates of authority, orders and approvals are
in full force and effect, and to the best knowledge of Norwest, no suspension or
cancellation of any of them is threatened; and all such filings, applications
and registrations are current. The conduct by Norwest and each Norwest
Subsidiary of its

                                     -15-
<PAGE>
 
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 Norwest nor any Norwest 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, no federal, state, municipal or other governmental authority has
placed any restrictions on the business or properties of Norwest or any Norwest
Subsidiary which reasonably could be expected to have a material adverse effect
on the business or properties of Norwest and its subsidiaries taken as a whole.

     (n)  Labor. No work stoppage involving Norwest or any Norwest Subsidiary is
pending or, to the best knowledge of Norwest, threatened. Neither Norwest nor
any Norwest Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding which could
materially and adversely affect the business of Norwest or such Norwest
Subsidiary. Except as set forth on Schedule 3(j), employees of Norwest and the
Norwest Subsidiaries are not represented by any labor union nor are any
collective bargaining agreements otherwise in effect with respect to such
employees.

     (o)  Norwest Benefit Plans.

          (i)  As of May 1, 1996, the only "employee benefit plans" within the
     meaning of Section 3(3) of ERISA for which Norwest or any Norwest
     Subsidiary acts as plan sponsor as defined in ERISA Section 3(16)(B) with
     respect to which any liability under ERISA or otherwise exists or may be
     incurred by Norwest or any Norwest Subsidiary are those set forth on
     Schedule 3(o) (the "Norwest Plans"). No Norwest Plan is a "multi-employer
     plan" within the meaning of Section 3(37) of ERISA.

          (ii)  Each Norwest Plan is and has been in all material respects
     operated and administered in accordance with its provisions and applicable
     law. Except as set forth on Schedule 3(o), Norwest or the Norwest
     Subsidiaries have received favorable determination letters from the
     Internal Revenue Service under the provisions of TEFRA, DEFRA and REA for
     each of the Norwest Plans to which the qualification requirements of
     Section 401(a) of the Code apply. Norwest knows of no reason that any
     Norwest Plan which is subject to the qualification provisions of Section
     401(a) of the Code is not "qualified" within the meaning of Section 401(a)
     of the Code and that each related trust is not exempt from taxation under
     Section 501(a) of the Code.

          (iii)  The present value of all benefits vested and all benefits
     accrued under each Norwest Plan which is subject to Title IV of ERISA did
     not, in each case, as determined for purposes of reporting on Schedule B to
     the Annual Report on Form 5500 of each such Norwest Plan as of the end of
     the most recent Plan year,

                                     -16-
<PAGE>
 
     exceed the value of the assets of the Norwest Plans allocable to such
     vested or accrued benefits.

          (iv)  Except as set forth on Schedule 3(o), and to the best knowledge
     of Norwest, no Norwest Plan or any trust created thereunder, nor any
     trustee, fiduciary or administrator thereof, has engaged in a "prohibited
     transaction", as such term is defined in Section 4975 of the Code or
     Section 406 of ERISA or violated fiduciary standards under Part 4 of Title
     I of ERISA, which could subject, to the best knowledge of Norwest, such
     Norwest Plan or trust, or any trustee, fiduciary or administrator thereof,
     or any party dealing with any such Norwest Plan or trust, to the tax or
     penalty on prohibited transactions imposed by said Section 4975 or would
     result in material liability to Norwest and its subsidiaries taken as a
     whole.

          (v)  Except as set forth on Schedule 3(o), no Norwest Plan which is
     subject to Title IV of ERISA or any trust created thereunder has been
     terminated, nor have there been any "reportable events" as that term is
     defined in Section 4043 of ERISA with respect to any Norwest Plan, other
     than those events which may result from the transactions contemplated by
     this Agreement and the Merger Agreement.

          (vi)  No Norwest Plan or any trust created thereunder has incurred any
     "accumulated funding deficiency", as such term is defined in Section 412 of
     the Code (whether or not waived), during the last five Norwest Plan years
     which would result in a material liability.

          (vii)  Neither the execution and delivery of this Agreement and the
     Merger Agreement nor the consummation of the transactions contemplated
     hereby and thereby will (i) result in any material payment (including,
     without limitation, severance, unemployment compensation, golden parachute
     or otherwise) becoming due to any director or employee or former employee
     of Norwest under any Norwest Plan or otherwise, (ii) materially increase
     any benefits otherwise payable under any Norwest Plan or (iii) result in
     the acceleration of the time of payment or vesting of any such benefits to
     any material extent.

     (p) Registration Statement, etc. None of the information regarding Norwest
and its subsidiaries supplied or to be supplied by Norwest for inclusion in (i)
the Registration Statement, (ii) the Proxy Statement, or (iii) any other
documents to be filed with the SEC or any regulatory authority in connection
with the transactions contemplated hereby or by the Merger Agreement will, at
the respective times such documents are filed with the SEC or any regulatory
authority and, in the case of the Registration Statement, when it becomes
effective and, with respect to the Proxy Statement, when mailed, be false or
misleading with respect to any material fact, or omit to state any material fact
necessary in order to make the statements therein not misleading or, in the case
of the Proxy Statement or any amendment thereof or supplement thereto, at the
time of the meeting of shareholders referred to in paragraph 4(c), be false or
misleading with respect to any

                                     -17-
<PAGE>
 
material fact, or omit to state any material fact necessary to correct
any statement in any earlier communication with respect to the solicitation of
any proxy for such meeting. All documents which Norwest and the Norwest
Subsidiaries are responsible for filing with the SEC and any other regulatory
authority in connection with the Merger will comply as to form in all material
respects with the provisions of applicable law.

     (q)  Brokers and Finders. Neither Norwest nor any Norwest Subsidiary nor
any of their respective officers, directors or employees has employed any broker
or finder or incurred any liability for any financial advisory fees, brokerage
fees, commissions or finder's fees, and no broker or finder has acted directly
or indirectly for Norwest or any Norwest Subsidiary in connection with this
Agreement and the Merger Agreement or the transactions contemplated hereby and
thereby.

     (r)  No Defaults. Neither Norwest nor any Norwest Subsidiary is in 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 Norwest and its subsidiaries taken as a whole. To the best
of Norwest's knowledge, all parties with whom Norwest or any Norwest Subsidiary
has material leases, agreements or contracts or who owe to Norwest or any
Norwest Subsidiary material obligations other than with respect to those arising
in the ordinary course of the banking business of the Norwest 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 Norwest or any Norwest 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, the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, pending or to the best of Norwest's
knowledge, threatened against Norwest or any Norwest Subsidiary, the result of
which has had or could reasonably be expected to have a material adverse effect
upon Norwest and its subsidiaries taken as a whole; to the best of Norwest's
knowledge there is no reasonable basis for any such proceeding, claim or action;
and to the best of Norwest's knowledge neither Norwest nor any Norwest
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. Merger Co. will have corporate power and authority to
enter into the Merger Agreement and to carry out its obligations thereunder.

Subsidiary will: maintain its corporate existence in good standing; maintain the
general character of its business and conduct its business in its ordinary and
usual manner; extend credit in accordance with existing lending policies, except
that it shall not, without the prior written consent of Norwest (which consent
requirement shall be deemed to be waived as to any loan approval request to
which Norwest has made no response by the end of the second business day
following receipt of the request), make any new loan or modify, restructure or
renew any existing loan (except pursuant to commitments made prior to the date
of this Agreement) to any borrower if the amount of the resulting loan, when
aggregated with all other loans or extensions of credit to such person, would be
in excess of $100,000; maintain proper business and accounting records in
accordance with generally accepted principles; maintain its properties in good
repair and condition, ordinary wear and tear excepted; maintain in all material

to obtain any approvals or consents required to maintain existing leases and
other contracts in effect following the Merger; comply in all material respects
with all laws, regulations, ordinances, codes, orders, licenses and permits
applicable to the properties and operations of Bancorp and each Bancorp
Subsidiary the non-compliance with which reasonably could be expected to have a
material adverse effect on Bancorp and the Bancorp Subsidiaries taken as a
whole; and permit Norwest and its representatives (including KPMG Peat Marwick)
to examine its and its subsidiaries books, records and properties and to
interview officers, employees and agents at all reasonable times when it is open
for business after reasonable notice. No such examination by Norwest or its
representatives either before or after the date of this Agreement shall in any
way affect, diminish or terminate any of the representations, warranties or
covenants of Bancorp herein expressed.

     (b)  Except as otherwise contemplated or required by this Agreement, from
the date hereof until the Effective Time of the Merger, Bancorp and each Bancorp
subsidiary will not (without the prior written consent of Norwest): amend or

hereof; declare, set aside, make or pay any dividend or other distribution with
respect to its capital stock except any dividend declared by a subsidiary's
Board of Directors in accordance with applicable law and regulation; provided,
however, that Bancorp may declare and pay dividends out of year-to-date 1996
earnings, in accordance with applicable law and regulation, in an aggregate
amount not to exceed $41,667 per month between December 31, 1995 and the Closing
Date; redeem, purchase or otherwise acquire, directly or indirectly, any of the
capital stock of Bancorp; increase the compensation of any officers, directors
or executive employees, except pursuant to existing compensation plans and
practices (including bonus plans), provided, however, that Bancorp may, in
addition, accrue and pay bonuses in accordance with Schedule 4(b) attached
hereto; sell or otherwise dispose of any shares of the capital stock of any
Bancorp Subsidiary; or sell or otherwise dispose of any of its assets or
properties other than in the ordinary course of business.

     (c)  The Board of Directors of Bancorp will duly call, and will cause to be
held not later than twenty-five (25) business days following the effective date

information concerning Bancorp and its subsidiaries required for inclusion in
the Registration Statement referred to in paragraph 5(c) hereof, or any
statement or application made by Norwest to any governmental body in connection
with the transactions contemplated by this Agreement. Any financial statement
for any fiscal year provided under this paragraph must include the audit opinion
and the consent of KPMG Peat Marwick LLP to use such opinion in such
Registration Statement.

     (e)  Bancorp will take all necessary corporate and other action and use its
best efforts to obtain all approvals of regulatory authorities, consents and
other approvals required of Bancorp to carry out the transactions contemplated
by this Agreement and will cooperate with Norwest to obtain all such approvals
and consents required of Norwest. Bancorp shall provide to Norwest, as soon as
reasonably practicable, all nonconfidential portions of applications filed with
and correspondence to or from regulatory authorities related to the consummation
of the transactions contemplated herein.

     (f)  Bancorp will use its best efforts to deliver to the Closing all
opinions, certificates and other documents required to be delivered by it at the
Closing.

                                     -20-
<PAGE>
 
     (g)  Bancorp will hold in confidence all documents and information
concerning Norwest and its subsidiaries furnished to Bancorp 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 Bancorp'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 Norwest (except to the extent that such
information can be shown to be previously known to Bancorp, in the public
domain, or later acquired by Bancorp from other legitimate sources) and, upon
request, all such documents, any copies thereof and extracts therefrom shall
immediately thereafter be returned to Norwest.

     (h)  Neither Bancorp, nor any Bancorp Subsidiary, nor any director,
officer, representative or agent thereof, will, directly or indirectly, solicit,
authorize the solicitation of or enter into any discussions with any
corporation, partnership, person or other entity or group (other than Norwest)
concerning any offer or possible offer (i) to purchase any shares of common
stock, any option or warrant to purchase any shares of common stock, any
securities convertible into any shares of such common stock, or any other equity
security of Bancorp or any Bancorp Subsidiary, (ii) to make a tender or exchange
offer for any shares of such common stock or other equity security, (iii) to
purchase, lease or otherwise acquire the assets of Bancorp or any Bancorp
Subsidiary except in the ordinary course of business, or (iv) to merge,
consolidate or otherwise combine with Bancorp or any Bancorp Subsidiary. If any
corporation, partnership, person or other entity or group makes an offer or
inquiry to Bancorp or any Bancorp Subsidiary concerning any of the foregoing,
Bancorp or such Bancorp Subsidiary will promptly disclose such offer or inquiry,
including the terms thereof, to Norwest.

     (i)  Bancorp shall consult with Norwest as to the form and substance of any
proposed press release or other proposed public disclosure of matters related to
this Agreement or any of the transactions contemplated hereby.

     (j)  Bancorp and each Bancorp Subsidiary will take all action necessary or
required (i) to terminate or amend, if requested by Norwest, all qualified

representatives in connection with the transactions contemplated by this
Agreement and will not release or disclose such information to any other person,

connection with this Agreement, with the same undertaking from such professional

acquired by Norwest from other legitimate sources) and, upon request, all such
documents, copies thereof or extracts therefrom shall immediately thereafter be
returned to Bancorp.

interests, they will not dispose of shares of Norwest or Bancorp during the
period commencing 30 days prior to the Effective Date and ending upon
publication by Norwest of financial results including at least 30 days of
combined operations of Bancorp and Norwest.

     (n)  For a period not exceeding fifteen days prior to the Closing Date,

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

          (i)  Norwest 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 Bancorp or any
     Bancorp Subsidiary, (an "Indemnified Party" and, collectively, the
     "Indemnified Parties") in Bancorp's Articles of Incorporation or By-laws or
     similar governing documents of any Bancorp 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 Bancorp or any Bancorp 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 Bancorp,
     Norwest shall guarantee, to the extent of the net asset value of Bancorp or
     any Bancorp Subsidiary as of the Effective Date of the Merger, the
     indemnification obligations of Bancorp or any Bancorp Subsidiary to the
     extent of indemnification obligations of Bancorp and the Bancorp
     Subsidiaries described above. Notwithstanding anything to the contrary
     contained in this paragraph 5(o)(i), nothing contained herein shall require
     Norwest to indemnify any person who was a director or officer of Bancorp or
     any Bancorp Subsidiary to a greater extent than Bancorp or any Bancorp
     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 Norwest thereof, but the
     failure to so notify shall not relieve Norwest 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 or after the Effective
     Time of the Merger), (A) Norwest shall have the right to assume the defense
     thereof and Norwest 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 Norwest elects not to assume such defense or counsel for the
     Indemnified Party advises that there are issues which raise conflicts of
     interest between Norwest and the Indemnified Party, the Indemnified Party
     may retain counsel satisfactory to them, and Norwest shall pay the
     reasonable fees and expenses of such counsel for the Indemnified Party
     promptly as statements therefor are received; provided, however, that
     Norwest shall be obligated pursuant to this subparagraph (ii) to pay for
     only one firm of counsel for all Indemnified Parties in

                                     -25-
<PAGE>
 
     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.

          (iii)  for a period of three years after the Effective Time of the
     Merger, Norwest shall use its best efforts to cause to be maintained in
     effect the current policies of directors' and officers' liability insurance
     maintained by Bancorp (provided that Norwest may substitute therefor
     policies of at least the same coverage and amount containing terms and
     conditions which are substantially no less advantageous) with respect to
     claims arising from facts or events which occurred before the Effective
     Time of the Merger; provided, however, that in no event shall Norwest be
     obligated to expend, in order to maintain or provide insurance coverage
     pursuant to this paragraph 5(o)(iii), any amount per annum in excess of
     125% of the amount of the annual premiums paid as of the date hereof by
     Bancorp for such insurance (the "Maximum Amount") and provided further
     that, prior to the Effective Time of the Merger, Bancorp shall notify the
     appropriate directors' and officers' liability insurers of the Merger and
     of all pending or threatened claims, actions, suits, proceedings or
     investigations asserted or claimed against any Indemnified Party, or
     circumstances likely to give rise thereto, in accordance with terms and
     conditions of the applicable policies.  If the amount of the annual
     premiums necessary to maintain or procure such insurance coverage exceeds
     the Maximum Amount, Norwest shall use reasonable efforts to maintain the
     most advantageous policies of directors' and officers' insurance obtainable
     for an annual premium equal to the Maximum Amount.

          (iv)   if Norwest or any of its successors or assigns (A) shall
     consolidate with or merge into any other corporation or entity and shall
     not be the continuing or surviving corporation or entity of such
     consolidation or Merger or (B) shall transfer all or substantially all of
     its properties and assets to any individual, corporation or other entity,
     then and in each such case, proper provision shall be made so that the
     successors and assigns of Norwest shall assume the obligations set forth in
     this paragraph 5(o).

          (v)    the provisions of this paragraph 5(o) are intended to be for
     the benefit of, and shall be enforceable by, each Indemnified Party and his
     or her heirs and representatives.

     6.  CONDITIONS PRECEDENT TO OBLIGATION OF BANCORP.  The obligation of

     9.  TERMINATION OF AGREEMENT.

     (a)  This Agreement may be terminated at any time prior to the Time of
Filing:

          (i)  by mutual written consent of the parties hereto;

          (ii)  by either of the parties hereto upon written notice to the other
     party if the Merger shall not have been consummated by December 31, 1996

     the covenants and agreements hereof to be performed or observed by such
     party;

          (iii)  by Bancorp or Norwest upon written notice to the other party if

          by the closing price of Norwest Common Stock on the trading day

<PAGE>
 
Common Stock"), and such other provisions with respect to said merger as are
deemed necessary or desirable, as follows:

     FIRST:  At the time of merger Merger Co. shall be merged with and into
Bancorp, one of the constituent corporations, which shall be the surviving
corporation, and the separate existence of Merger Co. shall cease and the name
of the surviving corporation shall be  ________________.

     SECOND:  The Articles of Incorporation of Bancorp at the time of merger
shall be amended as set forth below and, as so amended, shall be the Articles of
Incorporation of the surviving corporation until further amended according to
law:

          [Amend to change name, number of directors, etc.]

     THIRD:  The By-Laws of Bancorp at the time of merger shall be and remain
the By-Laws of the surviving corporation until amended according to the
provisions of the Articles of Incorporation of the surviving corporation or of
said By-Laws.

     FOURTH:  The directors of Merger Co. at the time of merger shall be and
remain the directors of the surviving corporation and shall hold office from the
time of merger until their respective successors are elected and qualify.

     FIFTH:   The officers of Merger Co. at the time of merger shall be and
remain the officers of the surviving corporation and shall hold office from the
time of merger until their respective successors are elected or appointed and
qualify.

     SIXTH:  The manner and basis of converting the shares of Bancorp Common
Stock into cash or shares of Norwest Common Stock shall be as follows:

     1.  Each of the shares of Bancorp Common Stock outstanding immediately
     prior to the time of merger (other than shares as to which statutory
     dissenters' rights have been exercised) shall at the time of merger, by
     virtue of the merger and without any action on the part of the holder or
     holders thereof, be converted into and exchanged for the number of shares
     of Norwest Common Stock determined by dividing 762,500 by the number of
     shares of Bancorp Common Stock then outstanding.

     2.  As soon as practicable after the merger becomes effective, each holder
     of a certificate for shares of Bancorp Common Stock outstanding immediately
     prior to the time of merger shall be entitled, upon surrender of such
     certificate for cancellation to the surviving corporation or to Norwest
     Bank Minnesota, National Association, as the designated agent of the
     surviving corporation (the "Agent"), to receive a new certificate for the
     number of whole shares of Norwest Common Stock to which such holder shall
     be entitled on the basis set forth in paragraph 1 above.  Until so
     surrendered each certificate which, immediately prior to the time of
     merger, represented shares of Bancorp Common Stock shall not be
     transferable on the books of the surviving corporation but shall be deemed
     to evidence the right to receive (except for the payment of dividends as
     provided below) ownership of the number of whole shares of Norwest Common
     Stock into which such shares of Bancorp Common Stock have been converted on
     the basis above set forth; provided, however, until the holder of such
     certificate for Bancorp Common Stock shall have surrendered the same for
     exchange as above set forth, no dividend payable to holders of record of
     Norwest Common Stock as of any date subsequent to the effective date of
     merger shall be paid to such holder with respect to the Norwest Common
     Stock, if any, represented by such certificate, but, upon surrender and
     exchange thereof as herein provided, there shall be paid by the surviving
     corporation or the Agent to the record holder of such certificate for
     Norwest Common Stock issued in exchange therefor an amount with respect to
     such shares of Norwest Common Stock equal to all dividends that shall have
     been paid or 

                                     -38-

<PAGE>
 
     become payable to holders of record of Norwest Common Stock between the
     effective date of merger and the date of such exchange.

     3.  If between the date of the Reorganization Agreement and the time of
     merger, shares of Norwest 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, then the number of shares of Norwest
     Common Stock, if any, into which a share of Bancorp Common Stock shall be
     converted on the basis above set forth, will be appropriately and
     proportionately adjusted so that the number of such shares of Norwest
     Common Stock into which a share of Bancorp Common Stock shall be converted
     will equal the number of shares of Norwest Common Stock which the holders
     of shares of Bancorp Common Stock would have received pursuant to such
     reclassification, recapitalization, split-up, combination, exchange of
     shares or readjustment, or stock dividend had the record date therefor been
     immediately following the time of merger.

     4.  No fractional shares of Norwest Common Stock and no certificates or
     scrip certificates therefor shall be issued to represent any such
     fractional interest, and any holder of a fractional interest 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 Norwest Common Stock as reported by the
     consolidated tape of the New York Stock Exchange for each of the five (5)
     trading days immediately preceding the meeting of shareholders held to vote
     on the merger.

     5.  Each share of Merger Co. Common Stock issued and outstanding at the
     time of merger shall be converted into and exchanged for one (1) share of
     the surviving corporation after the time of merger.


     SEVENTH:  The merger provided for by this Agreement shall be effective as
follows:

     1.  The effective date of merger shall be the date on which Articles of
     Merger (as described in subparagraph 1(b) of this Article Seventh) shall be
     delivered to and filed by the Secretary of State of the State of Texas;
     provided, however, that all of the following actions shall have been taken
     in the following order:

          a.  This Agreement shall be approved and adopted on behalf of Merger
          Co. and Bancorp in accordance with the Texas Business Corporation Act;
          and

          b.  Articles of merger (with this Agreement attached as part thereof)

          the Texas Business Corporation Act, shall be executed by the
          President or a Vice President of Merger Co. and by the Secretary or an
          Assistant Secretary of Merger Co., and by the President or a Vice
          President of Bancorp and by the Secretary or an Assistant Secretary of
          Bancorp, and shall be filed in the office of the Secretary of State of
          the State of Texas in accordance with the Texas Business Corporation
          Act.

     the Texas Business Corporation Act.

     necessary or desirable to vest, perfect or confirm in the surviving
     corporation the title to any property or rights of Merger Co. acquired or
     to be acquired as a result of the merger provided for herein, the proper
     officers and directors of Bancorp and Merger Co. may execute and deliver
     such deeds, assignments and assurances in law and take such other action as
     may be necessary or proper to vest, perfect or confirm title to such
     property or right in the surviving corporation and otherwise carry out the
     purposes of this Agreement.

Attn:  Secretary

Gentlemen:

     I have been advised that I might be considered to be an "affiliate," as
that term is defined for purposes of paragraphs (c) and (d) of Rule 145 ("Rule
145") promulgated by the Securities and Exchange Commission (the "Commission")
under the Securities Act of 1933, as amended (the "Securities Act") of Texas
Bancorporation, Inc., a Texas corporation ("Bancorp").

     Pursuant to an Agreement and Plan of Reorganization, dated as of ________,
1996, (the "Reorganization Agreement"), between Bancorp and Norwest Corporation,
a Delaware corporation ("Norwest") it is contemplated that a wholly-owned
subsidiary of Norwest will merge with and into Bancorp (the "Merger") and as a
result, I will receive in exchange for each share of Common Stock, par value
$0.01 per share, of Bancorp ("Bancorp Common Stock") owned by me immediately
prior to the Effective Time of the Merger (as defined in the Reorganization
Agreement), a number of shares of Common Stock, par value $1 2/3 per share, of
Norwest ("Norwest Common Stock"), as more specifically set forth in the
Reorganization Agreement.

     I hereby agree as follows:

     I will not offer to sell, transfer or otherwise dispose of any of the
shares of Bancorp Common Stock or Norwest Common Stock held by me during the 30
days prior to the Effective Time of the Merger.

     I will not offer to sell, transfer or otherwise dispose of any of the
shares of Norwest Common Stock issued to me pursuant to the Merger (the "Stock")
except (a) in compliance with the applicable provisions of Rule 145, (b) in a
transaction that is otherwise exempt from the registration requirements of the
Securities Act, or (c) in an offering registered under the Securities Act.

     I will not sell, transfer or otherwise dispose of the Stock or in any way
reduce my risk relative to any shares of Norwest Common Stock issued to me
pursuant to the Merger until such time as financial results covering at least 30
days of post-Merger combined operations of Bancorp and Norwest have been
published.

     I consent to the endorsement of the Stock issued to me pursuant to the
Merger with a restrictive legend which will read substantially as follows:

                                     -42-

<PAGE>
 
          "The shares represented by this certificate were issued in a
     transaction to which Rule 145 promulgated under the Securities Act of 1933,
     as amended (the "Act"), applies, and may be sold or otherwise transferred
     only in compliance with the limitations of such Rule 145, or upon receipt
     by Norwest Corporation of an opinion of counsel reasonably satisfactory to
     it that some other exemption from registration under the Act is available,
     or pursuant to a registration statement under the Act."

     Norwest's transfer agent shall be given an appropriate stop transfer order
and shall not be required to register any attempted transfer of the shares of
the Stock, unless the transfer has been effected in compliance with the terms of
this letter agreement.

     It is understood and agreed that this letter agreement shall terminate and
be of no further force and effect and the restrictive legend set forth above
shall be removed by delivery of substitute certificates without such legend, and
the related stop transfer restrictions shall be lifted forthwith, if (a) (i) any
such shares of Stock shall have been registered under the Securities Act for
sale, transfer or other disposition by me or on my behalf and are sold,
transferred or otherwise disposed of, or (ii) any such shares of Stock are sold
in accordance with the provisions of paragraphs (c), (e), (f) and (g) of Rule
144 promulgated under the Securities Act, or (iii) I am not at the time an
affiliate of Norwest and have been the beneficial owner of the Stock for at
least two years (or such other period as may be prescribed thereunder) and
Norwest has filed with the Commission all of the reports it is required to file
under the Securities Exchange Act of 1934, as amended, during the preceding
twelve months, or (iv) I am not and have not been for at least three months an
affiliate of Norwest and have been the beneficial owner of the Stock for at
least three years (or such other period as may be prescribed by the Securities
Act, and the rules and regulations promulgated thereunder), or (v) Norwest shall
have received an opinion of counsel acceptable to Norwest to the effect that the
stock transfer restrictions and the legend are not required, and (b) financial
results covering at least 30 days of post-Merger combined operations of Norwest
and Bancorp have been published.

     I have carefully read this letter agreement and the Reorganization
Agreement and have discussed their requirements and other applicable limitations
upon my ability to offer to sell, transfer or otherwise dispose of shares of
Bancorp Common Stock, Norwest Common Stock or the Stock, to the extent I felt
necessary, with my counsel or counsel for Bancorp.

                                       Sincerely,

                                       _________________________

                    (1) Any plan of merger to which the corporation is a party
               if shareholder approval is required by Article 5.03 or 5.16 of
               this Act and the shareholder holds shares of a class or series
               that was entitled to vote thereon as a class or otherwise:

                    (2) Any sale, lease, exchange or other disposition (not
               including any pledge, mortgage, deed of trust or trust indenture
               unless otherwise provided in the articles of incorporation) of
               all, or substantially all, the property and assets, with or
               without good will, of a corporation requiring the special
               authorization of the shareholders as provided by this Act;

                    (3) Any plan of exchange pursuant to Article 5.02 of this

          B.   Notwithstanding the provisions of Section A of this Article, a
               shareholder shall not have the right to dissent from any plan of

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 

                                      -2-
<PAGE>
 
               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 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 

                                      -3-
<PAGE>
 
               which the principal office of the domestic corporation is
               located, asking for a finding and determination of the fair 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 

                                      -4-
<PAGE>
 
               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 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

               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

<PAGE>
 
               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 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.

ITEM 22.  UNDERTAKINGS

  (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 posteffective 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,

                                      II-2
<PAGE>
 
               (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the registration
         statement or any material change to such information in the
         registration statement.

     (2) That, for the purpose of determining any liability under the Securities
         Act of 1933, each such posteffective 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.

     (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

                                      II-3
<PAGE>
 
the changes in volume and price represent no more than 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.  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, 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
posteffective 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.

     Ladies and Gentlemen:

          In connection with the proposed registration under the Securities
     Act of 1933, as amended, of up to 800,000 shares of common stock, par value
     $1-2/3 per share (the "Shares"), of Norwest Corporation, a Delaware
     corporation (the "Corporation"), which are proposed to be issued by the
     Corporation in connection with the merger (the "Merger") of a wholly-owned
     subsidiary of the Corporation with Texas Bancorporation, Inc., a Texas
     corporation, 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 Corporation 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 Corporation
     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.

                                 Very truly yours,

          Re:  Agreement and Plan of Reorganization by and Between Texas
               ---------------------------------------------------------
               Bancorporation, Inc. and Norwest Corporation
               --------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel to Texas Bancorporation, Inc. ("Bancorp"), a
corporation organized and existing under the laws of the State of Texas, in
connection with the proposed merger of [Merger Co.], a corporation organized and
existing under the laws of the state of _______________ ("Merger Co."), and
wholly-owned subsidiary of Norwest Corporation ("Norwest"), with and into
Bancorp, with Bancorp as the surviving corporation (the "Merger").  The Merger
will be effected pursuant to the Agreement and Plan of Reorganization by and
between Bancorp and Norwest dated as of June 3, 1996 (the "Agreement").  In our
capacity as counsel to Bancorp, our opinion has been requested with respect to
certain of the federal income tax consequences of the proposed Merger.

     In rendering this opinion, we have examined (i) the Internal Revenue Code
of 1986, as amended (the "Code") and Treasury regulations, (ii) the legislative
history of applicable sections of the Code, and (iii) appropriate Internal
Revenue Service and court decisional authority.  In addition, we have relied
upon certain information made known to us as more fully described below.  All
capitalized terms used herein without definition shall have the respective
meanings specified in the Agreement, and unless otherwise specified, all section
references herein are to the Code.

                            INFORMATION RELIED UPON
                            -----------------------

     In rendering the opinions expressed herein, we have examined such
documents as we have deemed appropriate, including:

     (1)  the Agreement;

     (2)  the Registration Statement on Form S-4 filed by Norwest with the
          Securities and Exchange Commission under the Securities Act of 1933,
          on ______________, 1996, including the Proxy Statement/Prospectus for
          the special meeting of the stockholders of Bancorp;

     (3)  such additional documents as we have considered relevant.

     In our examination of such documents, we have assumed, with your consent,
that all documents submitted to us as photocopies faithfully reproduce the
originals thereof, that such originals are authentic, that all such documents
have been or will be duly executed to the extent required, and that all
statements set forth in such documents are accurate.
<PAGE>
 
     We have also obtained such additional information and representations as we
have deemed relevant and necessary through consultation with various officers
and representatives of Norwest and Bancorp and through certificates provided by
the management of Norwest and the management of Bancorp.

     You have advised us that the proposed transaction will give Norwest a
strong presence in markets served by Bancorp and enable the combined
organization to realize certain operating efficiencies.  To achieve these goals,
the following will occur pursuant to the Agreement:

          (1) Subject to the terms and conditions of this Agreement, at the
Effective Time, Merger Co. shall be merged with and into Bancorp in accordance
with the laws of the State of Texas.  Bancorp shall be the Surviving Corporation
resulting from the Merger and shall become a wholly-owned Subsidiary of Norwest
and shall continue to be governed by the laws of the State of Texas.  The Merger
shall be consummated pursuant to the terms of the Agreement, which has been
approved and adopted by the respective Boards of Directors of Norwest, Merger
Co. and Bancorp and by the sole stockholder of Merger Co.

          (2) At the Effective Time, by virtue of the Merger, and without any
action on the part of Norwest, Bancorp, Merger Co. or the stockholders of any of
the foregoing, the shares of the constituent corporations shall be converted as
follows:

               (a) Each share of Norwest Common Stock issued and outstanding
immediately prior to the Effective Time shall remain issued and outstanding from
and after the Effective Time.

               (b) Each share of Merger Co. Common Stock issued and outstanding
immediately prior to the Effective Time shall be converted into and exchanged
for one share of the Surviving Corporation Common Stock.

               (c) Each share of Bancorp Common Stock issued and outstanding at
the Effective Time shall cease to be outstanding and shall be converted into and
exchanged for the number of shares of Norwest Common Stock determined by
dividing 775,000 by the number of shares of Bancorp Common Stock then
outstanding (the "Common Stock Exchange Ratio").


          (3) In the event Norwest changes the number of shares of Norwest
Common Stock, issued and outstanding prior to the Effective Time as a result of
a stock split, stock dividend, or similar recapitalization with respect to such
stock and the record date therefor (in the case of a stock dividend) or the
effective date thereof (in the case of a stock split or similar recapitalization
for which a record date is not established) shall be prior to the Effective
Time, the Common Stock Exchange Ratio shall be proportionately adjusted.

          (4) Notwithstanding any other provision of the Agreement, each holder
of shares of Bancorp Common Stock exchanged pursuant to the Merger who would
otherwise have been entitled to receive a fraction of a share of Norwest Common
Stock (after taking into account all certificates delivered by such holder)
shall receive, in lieu thereof, cash (without interest) in an amount equal to
such fractional part of a share of Norwest Common Stock multiplied by the
average of the closing prices of a share of Norwest Common Stock as reported by
the consolidated tape of the New York Stock Exchange for each of the five (5)
trading days ending on the day immediately preceding the meeting of shareholders
required by paragraph 4(c) of the Agreement.

          (5) Any holder of shares of Bancorp Common Stock who perfects his
dissenters' rights in accordance with and as contemplated by Texas Business
Corporation Act (the "TBCA") shall be entitled to receive the value of such
shares in cash as determined pursuant to such provision of Law; provided, that
no such payment shall be made to any dissenting shareholder unless and until
<PAGE>
 
such dissenting shareholder has complied with the applicable provisions of the
TBCA and surrendered to Norwest the certificate or certificates representing the
shares for which payment is being made.

     We have also assumed that the following statements are true on the date
hereof and will be true on the date on which the Merger is consummated:

          (1) The fair market value of the Norwest Common Stock and cash, if
any, received by each stockholder of Bancorp will, in each instance, be
approximately equal to the fair market value of the Bancorp Common Stock
surrendered in exchange therefor.

          (2) There is no plan or intention by any of the stockholders of
Bancorp who own one percent (1%) or more of the outstanding Bancorp Common
Stock, and to the best of the knowledge of the management of Bancorp, there is
no plan or intention on the part of the remaining stockholders of Bancorp to
sell, exchange, or otherwise dispose of a number of shares of Norwest Common
Stock received in the Merger that would reduce the Bancorp stockholders'
ownership of Norwest Common Stock to a number of shares having a value, as of
the date of the Merger, of less than fifty percent (50%) of the value of all of
the formerly outstanding stock of Bancorp immediately prior to the Merger.  For
purposes of this assumption, shares of Bancorp Common Stock exchanged for cash
or other property, surrendered by dissenters, or exchanged for cash in lieu of
fractional shares of Norwest Common Stock will be treated as outstanding Bancorp
Common Stock on the date of the Merger.  Moreover, shares of Bancorp Common
Stock held by Bancorp stockholders and otherwise sold, redeemed, or disposed of
prior or subsequent to the Merger will be considered in making this
representation.

          (3) Following the Merger, Bancorp will hold at least ninety percent
(90%) of the fair market value of its net assets and at least seventy percent
(70%) of the fair market value of its gross assets held immediately prior to the
Merger and at least ninety percent (90%) of the fair market value of Merger
Co.'s net assets and at least seventy percent (70%) of the fair market value of
Merger Co.'s gross assets held immediately prior to the Merger.  For purposes of
this assumption, amounts paid by Bancorp or Merger Co. to dissenters, amounts
paid by Bancorp or Merger Co. to stockholders who receive cash or other
property, amounts used by Bancorp or Merger Co. to pay reorganization expenses,
and all redemptions and distributions (except for regular, normal dividends)
made by Bancorp will be included as assets of Bancorp or Merger Co.,
respectively, immediately prior to the Merger.  Also for purposes of this
assumption, assets disposed of in contemplation of the Merger will be considered
as assets held by Bancorp immediately prior to the Merger.

          (4) Prior to the Merger, Norwest will be in control of Merger Co.  For
purposes of this assumption and those set forth below in paragraphs (5), (7),
(12), and (13), "control" means ownership of eighty percent (80%) of the total
combined voting power of all classes of stock entitled to vote and at least
eighty percent (80%) of the total number of all other classes of stock.

          (5) Bancorp has no plan or intention to issue additional shares of its
stock that would result in Norwest losing control of Bancorp.

          (6) Norwest has no plan or intention to reacquire any of its Common
Stock issued in the Merger.

          (7) Norwest will not liquidate Bancorp; merge Bancorp with or into
another corporation; sell or otherwise dispose of the stock of Bancorp except
for transfers of stock to corporations controlled by Norwest; or cause Bancorp
to sell or otherwise dispose of any of its assets or of any of the assets
acquired from Merger Co., except for dispositions made in the ordinary course of
business or transfers of assets to a corporation controlled by Norwest.

          (8) Merger Co. will have no liabilities assumed by Bancorp, and will
not transfer to Bancorp any assets subject to liabilities, in the Merger.
<PAGE>
 
          (9) Following the Merger, Bancorp will continue its historic business
or use a significant portion of its historic business assets in a business.

          (10) Norwest, Merger Co., Bancorp, and the stockholders of Bancorp
will pay their respective expenses, if any, incurred in connection with the
Merger.

          (11) There is no intercorporate indebtedness existing between Norwest
and Bancorp or between Merger Co. and Bancorp that was issued, acquired, or will
be settled at a discount.

          (12) Pursuant to the Merger, shares of Bancorp Common Stock
representing control of Bancorp will be exchanged solely for voting Common Stock
of Norwest.  For purposes of this assumption, shares of Bancorp Common Stock
exchanged for cash or other property originating with Norwest will be treated as
outstanding Bancorp Common Stock on the date of the Agreement.

          (13) At the time of the Merger, Bancorp will not have outstanding any
warrants, options, convertible securities, or any other type of right pursuant
to which any person could acquire stock in Bancorp that, if exercised or
converted, would affect Norwest's acquisition or retention of control of
Bancorp.

          (14) Norwest does not own, nor has it owned during the past five
years, any shares of the stock of Bancorp.

          (15) None of Norwest, Merger Co. nor Bancorp is an "investment
company."  For purposes of the foregoing, an "investment company" is a
corporation that is a regulated investment company, a real estate investment
trust, or a corporation fifty percent (50%) or more of the value of whose total
assets are stock and securities and eighty percent (80%) or more of the value of
whose total assets are assets held for investment.  In making the 50-percent and
80-percent determinations under the preceding sentence, stock and securities in
any subsidiary corporation shall be disregarded and the parent corporation shall
be considered a subsidiary if the parent owns 50 percent or more of the combined
voting power of all classes of stock entitled to vote, or 50 percent or more of
the total value of shares of all classes of stock outstanding.

          (16) On the date of the Merger, the fair market value of the assets of
Bancorp will exceed the sum of its liabilities, plus the amount of liabilities,
if any, to which the assets are subject.

          (17) Bancorp is not under the jurisdiction of a court in a case under
Title 11 of the United States Code or a receivership, foreclosure or similar
proceeding in a federal or state court.

          (18) The payment of cash to Bancorp stockholders in lieu of fractional
shares of Norwest Common Stock is solely for the purpose of avoiding the expense
and inconvenience of issuing and transferring fractional shares and does not
represent separately bargained for consideration.  The total cash consideration
that will be paid to Bancorp stockholders in lieu of fractional shares of
Norwest Common Stock will not exceed one percent (1%) of the total consideration
issued in the Merger to the stockholders of Bancorp in exchange for their shares
of Bancorp Common Stock.  The fractional share interest of each Bancorp
stockholder will be aggregated, and no stockholder of Bancorp will receive cash
in an amount equal to or greater than the value of one full share of Norwest
Common Stock.

          (19) None of the compensation received by any stockholder-employees of
Bancorp will be separate consideration for, or allocable to, any of their shares
of Bancorp Common Stock.  None of the shares of Norwest Common Stock received by
any stockholder-employees will be separate consideration for, or allocable to,
any employment agreement.  Any compensation paid to a Bancorp stockholder-
employee who continues as an employee of Norwest subsequent to the Merger will
be for services actually rendered and will be commensurate with amounts paid to
third parties bargaining at arm's-length for similar services.
<PAGE>
 
          (20) The Agreement represents the entire understanding of Norwest,
Bancorp, and Merger Co. with respect to the Merger.

                                   OPINIONS
                                   --------

          Based solely on the information submitted and the representations set
forth above, we are of the opinion that:

          (1) Provided the proposed merger of Merger Co. with and into Bancorp
qualifies as a statutory merger under the Texas Business Corporation Act, and
since (a) after the proposed transaction, Bancorp will hold substantially all of
its assets and substantially all of the assets of Merger Co. and (b) in the
transaction, the Bancorp stockholders will exchange an amount of stock
constituting control of Bancorp solely for Norwest Common Stock, the proposed
merger will constitute a reorganization within the meaning of section
368(a)(1)(A) of the Code.  The reorganization will not be disqualified by reason
of the fact that Norwest Common Stock is used in the transaction (section
368(a)(2)(E)).  For purposes of this opinion, "substantially all" means at least
90 percent (90%) of the fair market value of the net assets and at least 70
percent (70%) of the fair market value of the gross assets of Bancorp held
immediately prior to the proposed transaction.  Norwest, Merger Co., and Bancorp
will each be "a party to a reorganization" within the meaning of section 368(b)
of the Code.

          (2) No gain or loss will be recognized by Norwest upon the receipt of
Bancorp Common Stock solely in exchange for Merger Co. Common Stock.

          (3) No gain or loss will be recognized by Merger Co. on the transfer
of its assets to Bancorp solely in exchange for shares of Bancorp Common Stock.

          (4) No gain or loss will be recognized by Bancorp upon the receipt of
the assets of Merger Co. in exchange for shares of Bancorp Common Stock.

          (5) The stockholders of Bancorp will recognize no gain or loss upon
the receipt of Norwest Common Stock solely in exchange for their Bancorp Common
Stock.

          (6) The basis of the Norwest Common Stock received by the Bancorp
stockholders in the proposed transaction will, in each instance, be the same as
the basis of the Bancorp Common Stock surrendered in exchange therefor.

          (7) The holding period of the Norwest Common Stock received by the
Bancorp stockholders will, in each instance, include the period during which the
Bancorp Common Stock surrendered in exchange therefor was held, provided that
the Bancorp Common Stock was held as a capital asset on the date of the
exchange.

          (8) The payment of cash to Bancorp stockholders in lieu of fractional
share interests of Norwest Common Stock will be treated for federal income tax
purposes as if the fractional shares were distributed as part of the exchange
and then were redeemed by Norwest.  These cash payments will be treated as
having been received as distributions in full payment in exchange for the stock
redeemed.  Generally any gain or loss recognized upon such exchange will be
capital gain or loss, provided the fractional share would constitute a capital
asset in the hands of the exchanging stockholder.

          The opinions expressed herein are based upon existing statutory,
regulatory, and judicial authority, any of which may be changed at any time with
retroactive effect.  In addition, our opinions are based solely on the documents
that we have examined, the additional information that we have obtained, and the
statements set out herein, which we have assumed are true on the date the Merger
is consummated. Our opinions cannot be relied upon if any of the facts contained
in such documents
<PAGE>
 
or if such additional information is, or later becomes, inaccurate, or if any of
the statements set out herein is, or later becomes, inaccurate. Finally, our
opinions are limited to the tax matters specifically covered thereby, and we
have not been asked to address, nor have we addressed, any other tax
consequences of the proposed Merger, including, but not limited to, the tax
consequences of the recognition of deferred intercompany transactions and
adjustments necessary by reason of a change in accounting method.

          This opinion is being provided solely for the use of Texas
Bancorporation, Inc., Norwest Corporation, and the stockholders of Texas
Bancorporation, Inc.

          We hereby consent to the use of this opinion and to the references
made to the firm under the captions "Summary -- The Merger -- Certain Federal
Income Tax Consequences", "The Merger -- Certain Federal Income Tax
Consequences" and "Legal Matters" in the Proxy Statement/Prospectus constituting

     Re: Agreement and Plan of Reorganization By and Between
         Texas Bancorporation, Inc. and Norwest Corporation

Ladies and Gentlemen:

     We have acted as counsel to Texas Bancorporation, Inc. ("Bancorp"), a
corporation organized and existing under the laws of the state of Texas, in
connection with the proposed merger of a wholly-owned subsidiary of Norwest
Corporation ("Norwest"), with and into Bancorp, with Bancorp as the surviving
corporation (the "Merger"). The Merger will be effected pursuant to the
Agreement and Plan of Reorganization by and between Bancorp and Norwest dated as
of June 3, 1996 (the "Agreement"). In our capacity as counsel to Bancorp, our
opinion has been requested with respect to certain of the federal income tax
consequences of the proposed Merger.

     We have provided to Bancorp and Norwest the form of such opinion and we
hereby consent to the use of the form of such opinion and to the references made
to the firm under the captions "Summary--The Merger--Federal Income Tax
Consequences" and "Legal Matters" in the Proxy Statement-Prospectus constituting
part of the Registration Statement on Form S-4 of Norwest filed in connection
with the Merger.

                                    Very truly yours,

                                    THOMPSON & KNIGHT,
