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

issue whole shares of its Class A common stock and will make cash payments for
fractional shares. The number of shares of Bank United Corp. Class A common
stock you will receive for each share of Texas Central stock will be based on
the total number of shares of Texas Central stock outstanding on the closing
date of the merger. If the total number of shares of common stock of Texas
Central outstanding on the closing date is 350,340, then each share of Texas
Central stock will be converted into 2.0266 shares of Bank United Corp. Class A
common stock. The number of shares you receive may be reduced based on the
amount of certain fees and expenses incurred by Texas Central in connection with
the merger.

      This Proxy Statement/Prospectus also constitutes the Prospectus of Bank
United Corp. for the shares of its Class A common stock to be issued in the
merger. The shares of Class A common stock of Bank United Corp. are traded on

                       QUESTIONS AND ANSWERS ABOUT THE MERGER

      The following questions and answers highlight selected information
regarding the merger described in this Proxy Statement/Prospectus and may not
contain all information that is important to you as you consider the merits of
the merger. For a more complete description of the terms of the merger and the
related transactions, please read this entire Proxy Statement/Prospectus
carefully, as well as any additional documents referred to in this document.

Q:    WHY HAS TEXAS CENTRAL PROPOSED TO BE ACQUIRED BY BANK UNITED CORP.?

A:    The Board of Directors of Texas Central perceived that over the last
      several years the direction of the banking industry has been towards
      deregulation and consolidation, particularly in the State of Texas. The
      Board of Directors of Texas Central and certain of Texas Central's major
      shareholders felt that the organization needed to expand the boundaries of
      its franchise. Several options were discussed over a two or three year
      period. The acquisition of another institution or branching into
      additional communities in the Dallas area were considered.

      In January of 1999, the Board of Directors of Texas Central received a
      merger proposal from Bank United Corp. The Board reviewed the proposal and
      concluded that such a merger would be in the best interests of the Texas
      Central shareholders. The merger will permit Texas Central to expand
      services, such as providing trust services, on-line banking, cash
      management, in-house data processing and give Texas Central a larger
      network of branches and automated teller machines.

      For the reasons set forth above, the Texas Central Board of Directors
      believes the merger to be in the best interests of Texas Central's
      shareholders.

Q:    HOW WILL I BE AFFECTED IN THE MERGER?

A:    Shareholders of Texas Central will have their shares of Texas Central
      stock converted into whole shares of Bank United Corp. Class A common
      stock and cash for fractional shares. The actual number of shares of Bank
      United Corp. Class A common stock you will receive for each share of Texas
      Central stock will be based on the number of shares of Texas Central stock
      outstanding as of the closing date of the merger. If there are 350,340
      shares of Texas Central stock outstanding as of the closing, the maximum
      number of shares permitted under the merger agreement, each share of Texas
      Central stock will be converted into 2.0266 shares of Bank United Corp.
      Class A common stock. Any remaining fractional shares will be converted
      into cash based on the average daily closing prices of a share of Bank
      United Corp. Class A common stock for the 20 successive trading days
      ending on the trading that is one day prior to closing.

      For example, if a Texas Central shareholder owns 100 shares of Texas
      Central stock, after the merger, the shareholder will own 202 shares of
      Bank United Corp. Class A common stock and will receive a check for the
      market value of a 0.66 share of Bank United Corp. Class A common stock. On
      June 15, 1999, fractional shares would have been converted into cash based
      on $39.8125 as the value of a share of Bank United Corp. Class A common
      stock.

      Texas Central shareholders will receive shares representing ownership of
      approximately 710,000 shares of Bank United Corp. Class A common stock
      after the proposed merger. Each share owned by existing shareholders of
      Texas Central will represent an ownership interest in a much larger
      company.

Q:    WHEN CAN I SELL THE SHARES OF BANK UNITED CORP. CLASS A COMMON STOCK THAT
      I RECEIVE IN CONNECTION WITH THE MERGER?

A:    You may sell the shares of Class A common stock you receive in connection
      with the merger without restriction unless you are considered an
      "affiliate" of Texas Central or you become an affiliate of Bank United
      Corp. To review the restrictions on transfers by affiliates, see page 37.

                                       -3-
<PAGE>
Q:    WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

A:    Texas Central and Bank United Corp. expect that the exchange of shares in
      the merger will be a tax-free transaction for federal income tax purposes
      for Texas Central shareholders. However, Texas Central shareholders will
      have to pay taxes on cash received for fractional shares. To review the
      tax consequences to shareholders in greater detail, see page 34. The tax
      consequences of the merger to you will depend on your own situation. You
      should consult your tax advisors for a full understanding of the tax
      consequences of the merger to you.

Q:    WHAT RISKS SHOULD I CONSIDER?

A:    You should review the "RISK FACTORS" section on page 20.

Q:    WHEN WILL THE MERGER TAKE EFFECT?

A:    Texas Central and Bank United Corp. expect the merger to become effective
      in September of 1999.

Q:    CAN I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED PROXY CARD?

A:    Yes. After you have mailed your signed proxy card you can change your vote
      at any time before Texas Central votes your proxy at the meeting. You can
      do so in one of three ways prior to the meeting. First, you can send a
      written notice stating that you would like to revoke your proxy to the
      Corporate Secretary of Texas Central at the address given below. Second,
      you can complete a new proxy card and send it to the Corporate Secretary
      of Texas Central at the address given below. Third, you can attend the
      meeting and vote in person. You should send any written notice or new
      proxy card to the attention of the Corporate Secretary of Texas Central at
      8144 Walnut Hill Lane, Dallas, Texas 75231. You may request a new proxy
      card by calling the Corporate Secretary of Texas Central, at (214)
      691-8600.

Q:    WHAT IF I DO NOT APPROVE OF THE MERGER AND DO NOT WANT MY SHARES CONVERTED
      IF THE MERGER IS APPROVED?

A:    You may obtain dissenting shareholders rights by complying with the
      applicable requirements of the Texas Business Corporation Act. If all of

consumers and businesses from commercial banking offices in Dallas and Plano.
Since January 1, 1998, Texas Central has been a Subchapter S corporation for
federal income tax purposes. As an S corporation, Texas Central is generally
treated as a pass-through entity for federal income tax purposes, such that it
does not typically pay federal income tax on its earnings. Except as otherwise

January 1, 1998 contained in this Proxy Statement/Prospectus do not include
accruals or adjustments for the federal income tax Texas Central would have
incurred if it had not been an S corporation. As of March 31, 1999, Texas
Central had $120.6 million in assets, $100.2 million in deposits and $7.8
million in shareholders' equity. Texas Central's address is 8144 Walnut Hill

certain other conditions are met, Bank United Corp. will acquire Texas Central

agreement is attached as Exhibit A to this Proxy Statement/Prospectus. To
understand the merger more fully, you should carefully read the merger agreement
as well as this Proxy Statement/Prospectus.

THE SPECIAL MEETING AND VOTE REQUIRED

      Texas Central is holding a special shareholders' meeting at 3:00 p.m.,
local time, on Friday, July 30, 1999, at its principal executive office, 8144
Walnut Hill Lane, Dallas, Texas. The purpose of the meeting is for Texas Central
shareholders to consider and vote on the merger. The record date for the meeting
is the close of business on June 30, 1999. Only shareholders of record at the
close of business on the record date will be entitled to vote at the meeting and
any adjournment.

      Two-thirds of the outstanding shares of Texas Central stock must vote in
favor of the merger for the Texas Central shareholders to approve the merger.
Texas Central stock representing approximately 80% of such shares outstanding
have signed a Voting Agreement and Irrevocable Proxy in favor of Bank United
Corp. in which such shareholders have agreed to vote their Texas Central stock
in favor of the merger. Therefore, it is expected that the merger will be
approved at the meeting. The directors and executive officers of Texas Central
and Texas Central Bank own or otherwise control the right to

                                       -5-
<PAGE>
vote 68,870 shares of Texas Central stock, representing approximately 19% of the
shares of Texas Central stock issued and outstanding as of the record date. Of
the shares of Texas Central stock held by executive officers and directors,
43,880 shares, constituting approximately 13% of the total shares of Texas
Central stock, are subject to the Voting Agreement. The directors and executive
officers of Texas Central have indicated their intention to vote to approve the
merger.

REASONS FOR THE MERGER; RECOMMENDATION OF THE TEXAS CENTRAL BOARD OF DIRECTORS

      REASONS FOR THE MERGER. The Agreement is the result of arm's-length
negotiations between representatives of Bank United Corp. and Texas Central.
Upon receipt of a proposal from Bank United Corp., the Texas Central Board of
Directors carefully evaluated the proposal and concluded that the proposed
merger with Bank United Corp. was in the best interests of Texas Central and
Texas Central's shareholders for a number of reasons. The Board of Directors of
Texas Central perceived that over the last several years the direction of the
banking industry has been towards deregulation and consolidation, particularly
in the State of Texas. The Board of Directors of Texas Central and certain of
Texas Central's major shareholders felt that the organization needed to expand
the boundaries of its franchise. Several options were discussed over a two or
three year period. The acquisition of another institution or branching into
additional communities in the Dallas area were considered.

      In January of 1999, the Board of Directors of Texas Central received a
merger proposal from Bank United Corp. The Board reviewed the proposal and
concluded that such a merger would be in the best interests of the Texas Central
shareholders. The merger will permit Texas Central to expand services, such as
providing trust services, on-line banking, cash management, in-house data
processing and give Texas Central a larger network of branches and automated
teller machines.

      For the reasons set forth above, the Texas Central Board of Directors
believes the merger to be in the best interests of Texas Central's shareholders.

      RECOMMENDATION OF THE TEXAS CENTRAL BOARD OF DIRECTORS. Based on the
reasons set out above, the Board of Directors of Texas Central is of the opinion
that the merger is in the best interest of Texas Central and its shareholders
and recommends that you vote "FOR" the merger.

FAIRNESS OPINION

      In deciding to approve the merger, the Texas Central Board of Directors
received and considered the oral opinion of SAMCO Capital Markets, its financial
advisor, as to the fairness of the merger, from a financial point of view, to
the Texas Central shareholders as of such date. The oral opinion was confirmed
in writing on June 15, 1999, and a copy of the written opinion is attached as
Exhibit B to this Proxy Statement/Prospectus. You should read the opinion in its
entirety to understand the assumptions made, matters considered and limits of
the review undertaken by SAMCO Capital Markets in providing its opinion.

WHAT YOU WILL RECEIVE IN THE MERGER

      In exchange for shares of Texas Central stock, Bank United Corp. will
issue whole shares of Bank United Corp. Class A common stock and will make cash
payments for fractional shares. The number of shares of Bank United Corp. Class
A common stock you will receive for each share of Texas Central stock will be
based on the total number of shares of Texas Central stock outstanding on the
closing date of the merger. If there are 350,340 shares of Texas Central stock
outstanding as of the closing, the maximum number of shares permitted under the
merger agreement, each share of Texas Central stock will be converted into
2.0266 shares of Bank United Corp. Class A common stock.

      Instead of issuing you fractional shares of Bank United Corp. Class A
common stock, Bank United Corp. will pay you cash for such fractional shares. To
determine the amount you will receive for your fractional share, Bank United
Corp. will multiply the average of the daily closing sales prices for a share of
Bank United Corp. Class A common stock on the NASDAQ for the 20 successive
trading days ending on the trading day that is one day prior to the closing by
the share fraction you would otherwise receive.

                                       -6-
<PAGE>
      If the fees and expenses incurred by Texas Central in connection with the
merger agreement exceed $100,000, the amount of the excess will reduce the
number of shares you receive. The fees of Texas Central's financial advisor and
certain other expenses, however, are excluded from this calculation.

      The shares of Bank United Corp. Class A common stock issued in the merger
will be registered under applicable securities laws and will be authorized for
trading on the National Market System of The NASDAQ Stock Market.

                                       -8-

ADDITIONAL AGREEMENTS

      VOTING AGREEMENT. Pursuant to the merger agreement, five Texas Central
shareholders holding 280,950 shares of Texas Central stock, representing
approximately 80% of such shares outstanding, have entered into a Voting
Agreement and Irrevocable Proxy with Bank United Corp. Among other things, the
Voting Agreement requires that they vote their Texas Central stock in favor of
the merger at the meeting. Therefore, it is expected that the merger will be
approved at the meeting.

      NONCOMPETITION AGREEMENTS. It is a condition to Bank United Corp.'s
obligations to consummate the merger that it receive Noncompetition Agreements
from each person owning five percent or more of the Texas Central stock and from
each of the directors of Texas Central. The Noncompetition Agreements provide,
among other things, that for a three year period from the effective date of the
merger such individuals/entities will not solicit the business of Texas Central
Bank, its affiliates or it successors and will not compete with Texas Central
Bank, its affiliates or its successors within any county all or a portion of
which is included in the Dallas Consolidated Metropolitan Statistical Area. Each
of such persons has signed the required agreement to become effective as of the
closing of the merger.

      STOCK OPTION AGREEMENT. In connection with the merger agreement, Texas
Central and Bank United Corp. entered into a stock option agreement which
entitles Bank United Corp. to purchase 60,464 shares of Texas Central stock
representing approximately 15% of such stock at a price of $49.83 per share. The
option is exercisable upon the occurrence of certain events related to
significant corporate transactions at Texas Central that would prevent Bank
United Corp. from acquiring Texas Central or the acquisition of 30% or more of
the Texas Central stock by a person or group. The option contains a cash
settlement provision entitling Bank United Corp. to receive a cash payment
instead of exercising the option to acquire Texas Central stock.

RESALE OF BANK UNITED CORP. CLASS A COMMON STOCK RECEIVED IN THE MERGER

      Bank United Corp. has registered under the federal securities laws the
shares of its Class A common stock to be issued in the merger. Therefore, you
may sell such shares without restriction unless you are considered an
"affiliate" (as that term is used in the securities laws) of Texas Central or
you become an affiliate of Bank United Corp.

      If you are considered an affiliate of Texas Central or become an affiliate
of Bank United Corp., you may resell the shares of Bank United Corp. Class A
common stock only pursuant to an effective registration statement under the
securities laws, or pursuant to Rule 145 of the Commission's rules, or in
transactions otherwise exempt from registration under the securities laws. Bank
United Corp. is not obligated and does not intend to register for resale the
shares issued to affiliates of Texas Central. In addition, the Commission's
rules governing pooling of interests accounting prohibit resales by affiliates
of Texas Central of the Bank United Corp. Class A common stock until such time
as financial results covering at least 30 days of combined operations of Texas
Central and Bank United Corp. have been published.

      Each affiliate of Texas Central has signed a written agreement restricting
the transfer of shares of Bank United Corp. Class A common stock received in the
merger to transfers permitted by the federal securities laws and the
Commission's rules relating to pooling of interests accounting.

APPRAISAL RIGHTS

      Under Texas law, Texas Central shareholders may dissent from the merger
and demand the "fair value" of their shares in cash. To exercise this right, you
must not vote your shares in favor of the merger and you must take certain other
actions that Texas law requires. See page 34.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

      The merger has been structured as a "tax-free reorganization" for federal
income tax purposes. Accordingly, holders of Texas Central stock generally will
not recognize any gain or loss for federal income tax purposes on the exchange
of their Texas Central stock for Bank United Corp. Class A common stock in the
merger, except for any gain or loss recognized in connection with the receipt of
cash instead of a fractional share of Bank United Corp. Class A common stock.

                                       -9-
<PAGE>
The companies themselves will not recognize gain or loss as a result of the
merger. It is a condition to the obligations of Texas Central and Bank United
Corp. to complete the merger that each receive a legal opinion from its counsel
that the merger will be a tax-free reorganization for federal income tax
purposes. Neither Texas Central nor Bank United Corp. will request a ruling from
the Internal Revenue Service concerning the federal income tax consequences of
the merger. See page 33.

      The federal income tax consequences described above may not apply to some
holders of Texas Central stock. Your tax consequences will depend upon your
personal situation. You should consult your tax advisor for a full understanding
of the tax consequences of the merger to you.

COMPARATIVE SHAREHOLDER RIGHTS

      Once the merger occurs, Texas Central shareholders will become
stockholders of Bank United Corp. Texas Central is a Texas corporation and Bank
United Corp. is a Delaware corporation. As a result, your rights as a
shareholder, which now are governed by Texas corporate law and the provisions of
the Articles of Incorporation and Bylaws of Texas Central, will, after the
merger, be governed by Delaware corporate law and the provisions of the
Certificate of Incorporation and Bylaws of Bank United Corp. Because of
differences between the provisions of Texas corporate law and Delaware corporate
law, and differences between the Articles of Incorporation and Bylaws of Texas
Central and the Certificate of Incorporation and Bylaws of Bank United Corp.,
your rights as a shareholder will change as a result of the merger. See page 36.

ACCOUNTING TREATMENT

      It is expected that the merger will qualify as a pooling of interests for
accounting purposes, which means that Texas Central and Bank United Corp. will
be treated as if they had always been combined for accounting and financial
reporting purposes. It is a condition to Bank United Corp.'s obligation to
consummate the merger that Bank United Corp. receive a letter from its
accountants that the merger will qualify for pooling of interests accounting
treatment and a letter from Texas Central's accountants that it does not know of
a reason why the merger would not qualify for pooling. See page 36.

(1)   During fiscal 1997, Bank United Corp. sold certain of its mortgage
      origination offices. In connection with this sale, the remaining offices
      were restructured or closed. The mortgage origination branches shown at
      March 31, 1999 and 1998 and September 30, 1998 and 1997 are wholesale
      mortgage origination offices, which are currently part of the Financial
      Markets Group.

(2)   In connection with its acquisition, Bank United Corp. issued to the
      Federal Deposit Insurance Corporation, as manager of the Federal Savings
      and Loan Insurance Corporation Resolution Trust Fund, a warrant to acquire
      158,823 shares of common stock of Bank United. Payments in lieu of
      dividends related to the Warrant, which was redeemed in August 1996.
(3)   The extraordinary loss represents costs and charges associated with the
      repurchase and retirement of a majority of Bank United Corp.'s senior
      notes.

(4)   Effective October 1, 1997, Bank United Corp. adopted Statement of
      Financial Accounting Standard ("SFAS") No. 128, "Earnings per share,"
      which establishes standards for computing and presenting earnings per
      share ("EPS"). It requires dual presentation of basic and diluted EPS for
      entities with complex capital structures. All prior period EPS data were
      restated to comply with SFAS No. 128, but are not materially different.

(5)   Return on average assets is net income without deduction of minority
      interest, divided by average total assets.

(6)   Net operating expense ratio is total non-interest expense, less total
      non-interest income, as a percentage of average assets for each period.

(7)   Efficiency ratio is non-interest expense (excluding goodwill
      amortization), divided by net interest income plus non-interest income,
      excluding the gain on the sale of mortgage offices.

(8)   Adjusting items are composed of the following for fiscal 1999, 1998, 1997,
      1996, and 1994:

      --    1999 (decreased EPS $0.08)-- court of claims litigation expense
            totaling $4.1 million ($2.6 million net of tax);

      --    1998 (increased EPS $0.76) -- (1) two positive income tax
            adjustments totaling $33.5 million, (2) an increase in the
            commercial loan allowance of $7.8 million ($4.9 million net of tax),
            and (3) provisions for the impact of higher prepayments on the
            single family loan and servicing portfolios totaling $6.7 million
            ($4.2 million net of tax);

      --    1997 (increased EPS $0.02) -- (1) the gain on the sale of mortgage
            offices of $4.7 million ($2.9 million net of tax) and (2) an
            extraordinary loss on extinguishment of debt of $3.6 million ($2.3
            million net of tax);

      --    1996 (increased EPS $2.05) -- (1) a one-time SAIF assessment charge
            of $33.7 million ($20.7 million net of tax), (2) compensation
            expense of $7.8 million ($4.8 million net of tax), (3) charges
            totaling $12.5 million ($7.7 million net of tax) related to the
            restructuring of and items associated with the mortgage origination
            business, (4) a contractual payment to previous minority interests
            of $5.9 million, and (5) an income tax benefit of $101.7 million;

      --    1994 (increased EPS $1.90)-- an income tax benefit of $58.2 million.

(9)   Where appropriate, ratios for the interim periods have been annualized.

(1)   Variances between March 31, 1999 and March 31, 1998 can be attributed to
      the opening of the Park Cities branch location in May 1998.

(2)   The variance for 1995 is attributed to a single credit charged off during
      that year. The subsequent year received a partial recovery of this
      charge-off.

(3)   The loss during 1997 is attributed to the sale of a mutual fund.

(4)   Texas Central elected S corporation status effective January 1, 1998.

(5)   Distributions made to shareholders during 1998 were for the payment of tax
      liability associated with the income passed through to them due to the
      Texas Central's S corporation election.

(6)   Return on average assets is net income divided by average total assets.

(7)   Net operating expense ratio is total non-interest expense, less total
      non-interest income, as a percentage of average assets for each period.

(8)   Efficiency ratio is non-interest expense, divided by net interest income
      plus non-interest income.

(9)   Where appropriate, certain ratios for the interim periods have been
      annualized.

SUMMARY OF HISTORICAL AND PRO FORMA PER SHARE SELECTED FINANCIAL DATA

      Set forth below are the net earnings, diluted earnings, cash dividends and
book value per common share data for Bank United Corp. and Texas Central on a
historic basis, on a pro forma combined basis and on a pro forma combined basis
per Texas Central equivalent share. Also included are weighted average shares
outstanding and shares outstanding at end of period for Bank United Corp., Texas
Central and on a pro forma basis. The exchange ratio for the merger is assumed
to be 2.0266 shares of Bank United Corp. Class A common stock for each share of
Texas Central stock.

      The pro forma data was derived by combining the historic consolidated
financial information of Bank United Corp. and Texas Central using the pooling
of interests method of accounting for business combinations.

      The Texas Central pro forma equivalent share information shows the effect
of the merger from the perspective of an owner of Texas Central stock. The
information was computed by multiplying the pro forma information by an exchange
ratio of 2.0266.

      You should read the information below together with historical financial
statements and related notes and other information included in this Proxy
Statement/Prospectus and incorporated by reference. The unaudited pro forma
combined data below is for illustrative purposes only. The companies may have
performed differently had they always been combined. You should not rely on this
information as being indicative of the historical results that would have been
achieved had the companies always been combined or the future results that the
combined company will experience after the merger.

SHARES ENTITLED TO VOTE, QUORUM AND VOTE REQUIRED

      The holders of record of the outstanding Texas Central stock at the close

stock issued and outstanding as of the record date. Of the shares of Texas
Central stock held by executive officers and directors, 43,880 shares,

                                     THE MERGER

      The following information relating to the merger is not intended to be a
complete description of all information relating to the merger and is qualified
in its entirety by reference to more detailed information contained elsewhere in
this Proxy Statement/Prospectus, including the Exhibits hereto and the documents
referred to herein or incorporated herein by reference. A copy of the merger
agreement is included as Exhibit A. All shareholders of Texas Central are urged
to read the merger agreement in its entirety.

TERMS OF THE MERGER

      The merger agreement provides for the merger of BUC Acquisition with and
into Texas Central. The merger will be effective as soon as practicable
following the receipt of all necessary regulatory approvals and the satisfaction
of all conditions to the consummation of the merger. As a result of the merger,
holders of Texas Central stock (other than those shareholders who perfect their
dissenters' rights of appraisal) will be entitled to receive whole shares of
Bank United Corp. Class A common stock and cash for fractional shares and will
no longer be owners of Texas Central stock. As a result of the merger,
certificates for Texas Central stock will only represent the right to receive
the merger consideration pursuant to the merger agreement, and otherwise will be
null and void after such date. Assuming the number of outstanding shares of
Texas Central is 350,340, the maximum number permitted by the merger agreement,
each share of Texas Central stock will be converted into the right to receive
2.0266 shares of Bank United Corp. Class A common stock, subject to adjustment
as described below.

      Bank United Corp. will not issue any certificates for fractional shares of
Bank United Corp. Class A common stock in connection with the merger. Instead of
issuing fractional shares, Bank United Corp. will pay cash for such fractional
shares in an amount based on the average of the daily closing bid sales prices
for a share of Bank United Corp. Class A common stock on the NASDAQ for the 20
successive trading days ending on the trading day that is one day prior to the
closing.

      The merger agreement provides that legal, accounting and other fees and
expenses incurred by Texas Central in connection with the merger agreement in
excess of $100,000 will be deducted from the merger consideration. However, the
fee to be paid to SAMCO Capital Markets, the financial adviser to Texas Central,
and fees, expenses and payments associated with the funding or payment of
bonuses, incentive compensation plans and vacation pay required by the merger
agreement will not be included in the calculation of the $100,000 limit and will
not be deducted from the merger consideration.

SHAREHOLDER APPROVAL

      The merger agreement must be approved by the affirmative vote of the
holders of two-thirds of the outstanding shares of Texas Central stock entitled
to vote at the meeting. Of the 350,340 shares of Texas Central stock outstanding
on the record date, the holders of 233,560 shares must vote in favor of the
merger in order for it to be approved. The holders of 280,950 shares of Texas
Central stock, representing approximately 80% of such shares outstanding, are
parties to the Voting Agreement in which they have agreed, among other things,
to vote in favor of the merger at the meeting. Therefore, it is expected that
the merger will be approved at the meeting. Bank United Corp. is expected to
approve the merger as the sole shareholder of BUC Acquisition.

BACKGROUND AND REASONS FOR THE MERGER; RECOMMENDATION OF TEXAS CENTRAL BOARD

      The Board of Directors of Texas Central has approved the Agreement as
being in the best interests of Texas Central and its shareholders, and the Board
of Directors of Bank United Corp. has also approved the Agreement as being in
the best interests of Bank United Corp. and Bank United Corp.'s shareholders. If
the transactions contemplated by the Agreement are consummated, Texas Central
will be merged with and into a subsidiary of Bank United Corp., its separate
existence will cease, and present Texas Central shareholders will become
shareholders Bank United Corp.

                                       -23-
<PAGE>
      The Board of Directors of Texas Central perceived that over the last
several years, the direction of the banking industry has been towards
deregulation and consolidation, particularly in the State of Texas. The Board of
Directors of Texas Central and certain of Texas Central's major shareholders
felt that the organization needed to expand the boundaries of its franchise.
Several options were discussed over a two or three year period. The acquisition
of another institution or branching into additional communities in the Dallas
area were considered. The Board of Directors' review of alternatives continued
through 1998. In January of 1999, the Board of Directors of Texas Central
received a merger proposal from Bank United Corp. The Board reviewed the
proposal and concluded that such a merger would be in the best interests of the
Texas Central shareholders. The merger will permit Texas Central to expand
services, such as providing trust services, on-line banking, cash management,
in-house data processing and offer its customers a larger network of branches
and automated teller machines.

      For the reasons set forth above, the Texas Central Board of Directors
approved the merger and recommends approval of the transaction by the Texas
Central shareholders.

      The Board of Directors of Bank United Corp. believes that acquiring Texas
Central will allow Bank United Corp. to expand and strengthen its presence in
the Dallas metropolitan area and will also result in some economies of scale.

      Following arm's length negotiations between representatives of Bank United
Corp. and Texas Central, the merger agreement was executed on March 23, 1999.
The aggregate consideration to be paid to the holders of Texas Central stock
resulted from negotiations which considered the historical earnings and
dividends of Texas Central and Bank United Corp., the earnings potential and
deposit base of Texas Central, potential growth in the Dallas market, Texas
Central's asset quality and the effect of the merger on the shareholders,
customers and employees of Texas Central and Bank United Corp.

      Subject to satisfaction of certain conditions contained in the merger
agreement, the Texas Central Board of Directors believes the merger to be fair
and in the best interest of Texas Central and its shareholders. In addition, a
fairness opinion has been obtained from SAMCO Capital Markets with respect to
the fairness, from a financial point of view, of the merger to the Texas Central
shareholders. THE TEXAS CENTRAL BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
THE TEXAS CENTRAL SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER and has
authorized consummation of the merger, subject to approval of Texas Central
shareholders, federal and state bank regulators and the satisfaction of certain
other conditions.

FAIRNESS OPINION

      In deciding to approve the merger, the Texas Central Board of Directors
received and considered the oral opinion of SAMCO Capital Markets ("SAMCO"), its
financial advisor, as to the fairness of the merger to the Texas Central
shareholders from a financial point of view as of such date. The oral opinion
was confirmed in writing on June 15, 1999, and a copy of the written opinion is
attached as Exhibit B to this Proxy Statement/Prospectus. You should read the
opinion in its entirety to understand the assumptions made, matters considered
and limits of the review undertaken by SAMCO in providing its opinion.

      SAMCO, a division of Service Asset Management Company, is regularly
engaged in the business of evaluating financial institutions and their
securities in connection with mergers and acquisitions, and in evaluations for
other purposes. On September 10, 1998, Texas Central engaged SAMCO to act as an
independent financial advisor to Texas Central's Board of Directors and
shareholders in connection with the merger. Specifically, based on SAMCO's
reputation and qualifications in evaluating financial institutions, the Board of
Directors of Texas Central requested that SAMCO render advice and analysis in
connection with the merger, and to provide an opinion with regard to the
fairness, from the perspective of the shareholders of Texas Central of the
financial terms of the merger.

      SAMCO has rendered a written opinion to the Board of Directors of Texas
Central to the effect that the terms of the merger are fair, from a financial
point of view, to the shareholders of Texas Central as of the date of the
opinion letter. A copy of the opinion letter is attached as Exhibit B to this
Proxy Statement/Prospectus and should be read in its entirety by the Texas
Central shareholders.

      SAMCO based its opinion upon, among other things, a review of:

      o     certain publicly available financial statements and other
            information of Texas Central and Bank United Corp.;

      o     certain internal financial statements and other financial and
            operating data concerning Texas Central and Bank United Corp.
            prepared by the management of Texas Central and Bank United Corp.;

            prospects of Bank United Corp. and the estimated pro forma impact of
            the merger, including on the combined company's earnings per share,

      SAMCO also reviewed such other information, including financial studies,
analyses, investigations and economic and market criteria, that SAMCO deemed
relevant to its engagement. SAMCO maintains a sizable database of information
pertaining to prices paid for banks in the United States. The database includes
transactions involving banking organizations in Texas and the Southwest Region
of the United States, and provides comparable pricing of financial performance
data for banking organizations. SAMCO has the capability of sorting such records
to yield transactions involving similar banks. Similarities might include banks
within a specified asset size range, banks that generate a return on average
assets within a specified range, banks that have an equity-to-assets ratio
within a certain range, or banks that sold for a specific form of consideration
(such as cash or stock). The ability to produce specific groups of comparable
banks facilitates making a valid comparative analysis.

      SAMCO considered twenty-one transaction values for Texas banks with assets
greater that $75 million and less than $250 million announced between January 1,
1997 and March 1, 1999 for which publicly available pricing information is
available. For these twenty-one transactions, the average price/book was 2.74
times, price/earnings 19.59 times, price/assets 22.05%, price/deposits 24.70%,
and tangible book premium/core deposits 17.82%. Based on comparability pricing
to these transactions, a range of $54 to $75 a share for control of Texas
Central was calculated.

                                      -25-
<PAGE>
      SAMCO compared transaction values, and the corresponding characteristics
for the relevant banks, in relation to the transaction value in the context of
the acquisition of Texas Central by Bank United Corp. The comparative analysis
revealed that the merger yields a higher price than the comparative transactions
pricing range. Generally, higher performing banks command higher prices than
lower performing ones. The average performance ratios for these transactions
were a 1.37% return on assets and a 15.23% return on equity, for which Texas
Central comparatively had a slightly higher 1.38% return on assets and a higher
19.36% return on equity.

      Since the form of consideration in the merger involves the exchange of
Bank United Corp. Class A common stock for the shares of Texas Central, SAMCO
evaluated the financial condition and performance of Bank United Corp. SAMCO
conducted its own independent financial analysis of Bank United Corp. based upon
the aforementioned information provided to or obtained by SAMCO. SAMCO also
reviewed and considered financial analyses and earnings forecasts produced by
financial analysts affiliated with various brokerage and investment banking
firms that cover the financial institutions industry in general, and Bank United
Corp. in particular. The intent of this financial analysis is to ascertain the
current financial condition and future earnings prospects of Bank United Corp.
given that the current shareholders of Texas Central will have an ownership in
Bank United Corp. following the transaction. SAMCO is satisfied with the
findings obtained from its financial analyses regarding the financial condition
and earnings prospects of Bank United Corp., and believes that sufficient
foundation exists in this regard to support SAMCO's conclusion regarding the
financial fairness of the proposed transaction.

      SAMCO is of the belief that its review of, among other things, the
aforementioned items, provides a reasonable basis for the issuance of its
opinion, recognizing that SAMCO is issuing an informed professional opinion, not
a certification of value. No limitations were imposed on the scope of SAMCO's
investigation by either Bank United Corp. or Texas Central.

      SAMCO, as part of its professional services, specializes in rendering
valuation opinions of banks and bank holding companies in connection with
mergers and acquisitions nationwide. For SAMCO's services as an independent
financial analyst and advisor to Texas Central in connection with the merger,
Texas Central paid SAMCO a professional fee of $500,000. The professional fees
billed by SAMCO for services provided to Texas Central (including both the fees
for services provided in the past and fees for SAMCO's evaluation of the merger)
are insignificant as compared to SAMCO's total annual billings.

      SAMCO relied upon the information provided by the management of Texas
Central and Bank United Corp., or otherwise reviewed by SAMCO, as being complete
and accurate in all material respects. SAMCO has not verified through
independent inspection or examination the specific assets or liabilities of
Texas Central, Bank United Corp. or their subsidiary banks. SAMCO has assumed
that there has been no material change in assets, financial condition, results
of operation or business prospects of Texas Central and Bank United Corp. since
the date of the last financial statements made available to SAMCO. SAMCO met
with the management of Texas Central and Bank United Corp. for the purpose of
discussing the relevant information that has been provided to SAMCO.

      Based on all factors that SAMCO deemed relevant and assuming the accuracy
and completeness of the information and data provided, SAMCO concluded that the
provisions of the proposed merger, specifically the terms of the exchange ratio,
as outlined herein, are fair, from a financial standpoint, to the common
shareholders of Texas Central.

<PAGE>

Therefore, it is expected that the merger will be approved at the meeting.

      EMPLOYMENT AND CONSULTING AGREEMENTS. Pursuant to the merger agreement,
Bank United has entered into an Employment Agreement and Agreement Not to
Compete with three officers of Texas Central Bank: James C. Veirs, Gary D.
Mulhollen and Keith Schmidt. These individuals will be employed by Bank United
for two years commencing on the effective date of the merger. Mr. Veirs will
receive an annualized base salary of $181,120, Mr. Mulhollen an annualized base
salary of $105,000 and Mr. Schmidt an annualized base salary of $80,000. In

employment agreement includes a provision which prohibits the employee from
soliciting the business of Bank United or competing with Bank United within any

      Pursuant to the merger agreement, Michael A. Ruff, an executive officer of
Texas Central, and Bank United have entered into a Consulting Agreement whereby
Mr. Ruff will consult with Bank United for a six-month period commencing on the
effective date of the merger. Mr. Ruff will receive a consulting fee of
$8,333.34 per month.

      NONCOMPETITION AGREEMENTS. It is a condition to Bank United Corp.'s
obligations to consummate the merger that it receive Noncompetition Agreements
from each person owning five percent or more of the Texas Central stock and from
each of the directors of Texas Central. The Noncompetition Agreements provide,
among other things, that for a three year period from the effective date of the
merger such individuals/entities will not solicit the business of Texas Central
Bank, its affiliates or it successors and will not compete with Texas Central
Bank, its affiliates or its successors within any county all or a portion of
which is included in the Dallas Consolidated Metropolitan Statistical Area. Each
of these persons has signed the required agreements to become effective as of
the closing of the merger.

      STOCK OPTION AGREEMENT. Texas Central has granted Bank United Corp. the
option to purchase up to 60,464 shares of Texas Central stock, representing
approximately 15% of the shares to be outstanding if it were exercised, at a
purchase price of $49.83 per share pursuant to the Stock Option Agreement. Bank
United Corp. may exercise its option following:

      o     the occurrence of certain events related to:

            oo    the merger or consolidation of Texas Central or any of its
                  subsidiaries,

            oo    the transfer of 10% or more of the consolidated assets of
                  Texas Central, or

            oo    the issuance of securities representing 20% or more of the
                  voting power of Texas Central.

      o     the acquisition of or right to acquire beneficial ownership of 30%
            or more of the voting power of Texas Central by a person or group.

      At Bank United Corp.'s option, or if banking regulators fail to approve
Bank United Corp.'s acquisition of the Texas Central stock pursuant to the Stock
Option Agreement, then Bank United Corp. may elect to receive cash in exchange
for the cancellation of the option rather than the receipt of Texas Central
stock. The amount of cash received if this "cash out" alternative is elected
depends on the event that triggers the exercise of the stock option. If the
option is triggered by the merger of Texas Central with another person, then the
cash payment received by Bank United Corp. will be based on the amount paid to
the Texas Central shareholders in the merger. For other triggering events that
do not involve the acquisition of Texas Central by another person, the cash
payment to be received by Bank United Corp. will be determined by reference to
the value of the Class A common stock of Bank United Corp.


                                       -29-
<PAGE>
      The option will terminate upon:

            o     the effectiveness of the merger,

            o     15 days after an event triggering the option, or

            o     termination of the merger agreement in accordance with its
                  terms prior to the occurrence of an event triggering the
                  option.

      AFFILIATE AGREEMENTS. Pursuant to the merger agreement, the directors,
executive officers of Texas Central and certain principal shareholders of Texas
Central have entered into Affiliate Agreements with Bank United Corp. pursuant
to which they have agreed, among other things, not to offer to sell, sell,
transfer or otherwise dispose of any shares of Bank United Corp. Class A common
stock acquired by them in the merger until the publication of financial results
covering at least 30 days of post-merger combined operations of Bank United
Corp. and Texas Central. Even after such publication, they have agreed to
dispose of Bank United Corp. Class A common stock only (i) in accordance with
the applicable provisions of Rule 145 promulgated under the Securities Act of
1933; (ii) in a transaction that is exempt from the registration requirements of
the Securities Act or (iii) in an offering registered under the Securities Act.

BUSINESS PENDING EFFECTIVE TIME

      The merger agreement imposes certain limitations on the conduct of Texas
Central's business pending consummation of the merger. Among other things, Texas
Central must conduct its businesses only in the ordinary course, consistent with

amount equal to 39.6% of the taxable income of Texas Central as approved by Bank

      CREDIT FOR SERVICE WITH TEXAS CENTRAL BANK. All employees who are offered
and accept employment with Bank United as of the effective date shall be
eligible to participate in the employee benefit plans and other fringe benefits
of Bank United on the same basis as such plans and benefits are offered to
employees of Bank United with comparable positions with Bank United. To the
extent possible under its employee benefit plans, Bank United shall credit such
employees for their length of service with Texas Central Bank for purposes of
eligibility and vesting under each employee benefit and fringe benefit plan to
be provided by Bank United to such employees, to the same extent such service
was recognized under a similar plan of Texas Central Bank; provided, however,
credit for prior service will not apply to the incentive compensation, pension,
profit sharing, retirement and post retirement welfare benefits, and vacation
plans of Texas Central Bank.

            by the Boards of Directors of Bank United Corp. and Texas Central.

The right to terminate under the last item above is not available to any party

abandoned at any time by Texas Central if:

      o     Bank United Corp. fails to comply in any material respect with any

            untrue in any material respect,

      o     the average of the daily closing sales prices for a share of Bank

abandoned at any time by Bank United Corp. if:

      o     Texas Central fails to comply in any material respect with any of
            its covenants or agreements contained in the merger agreement, or if
            any of the representations or warranties of Texas Central are
            defective in any material respect,

      o     there shall have been any change after December 31, 1998, in the
            assets, liabilities (including deposit liabilities), properties,
            business or financial condition of Texas Central which individually
            or in the aggregate have materially and adversely affected the
            financial condition, results of operation or business of Texas
            Central, or

                                       -31-

            Corp. will be unable to obtain any regulatory approval required in
            order to consummate the merger.

In the event the Board of Directors of Bank United Corp. desires to terminate
the merger agreement because of an alleged breach, inaccuracy or change as
provided in either of the first two items above, Bank United Corp. must notify
Texas Central in writing of its intent to terminate stating the cause therefor.
Texas Central has 15 days from the receipt of the notice to cure the alleged
breach, inaccuracy or change, subject to the approval of Bank United Corp.
(which approval may not be unreasonably delayed or withheld).

      REMEDIES. In the event of the termination of the merger agreement without
breach by any party hereto, the merger agreement will be void and have no
effect, without liability on the part of any party or the directors, officers or
shareholders of any party. A termination of the merger agreement will not
relieve a party of any liability for breach of the merger agreement. Bank United
Corp.'s remedy for a breach by Texas Central of the representation contained in
the merger agreement regarding Texas Central's reserve for possible loan losses
is limited to the termination of the merger agreement and the receipt of a cash
payment from Texas Central equal to the actual out of pocket expenses incurred
by Bank United Corp. in connection with the transactions contemplated by the
merger agreement not to exceed $250,000.

EXPENSES

      Whether or not the merger is consummated, each party to the merger
agreement will pay its respective expenses incurred in connection with the
preparation and performance of its obligations under the merger agreement.
Except as to the fee to be paid by Texas Central to SAMCO Capital Markets, not
to exceed $500,000, each party agrees to indemnify the other party against any
cost, expense or liability (including reasonable attorneys' fees) in respect of
any claim made by any party for a broker's or finder's fee in connection with
the merger other than one based on communications between the party and the
claimant seeking indemnification.

      The merger agreement provides that legal, accounting and other fees and
expenses incurred by Texas Central in connection with the merger agreement in
excess of $100,000 will reduce the number of shares issuable in the merger.
However, the fee to be paid to SAMCO Capital Markets, and the fees,
expenses and payments associated with the funding or payment of bonuses,
incentive compensation plans and vacation pay required by the merger agreement,
will not be included in the calculation of the $100,000 limit and will not be
deducted from the merger consideration:

EXCHANGE OF SHARES

      Prior to the effective date of the merger, Bank United Corp. will deposit
in trust with an exchange agent to be selected by Bank United Corp. (the
"Exchange Agent") certificates representing a number of shares of Bank United
Corp. Class A common stock sufficient to pay the merger consideration and the
cash to be paid in lieu of fractional shares. Soon after the effective date of
the merger, the Exchange Agent will mail to each holder of an outstanding
certificate or certificates which as of the effective date represented shares of
Texas Central stock (the "Certificates"), a letter of transmittal for use in the
exchange and instructions explaining how to surrender the Certificates to the
Exchange Agent. Upon surrender to the Exchange Agent of a Certificate, together
with such letter of transmittal duly executed, the holder of such Certificate
shall be entitled to receive in exchange therefor (i) a certificate representing
the number of whole shares of Bank United Corp. Class A common stock to which
such holder is entitled pursuant to the merger agreement and (ii) a check
representing the amount of cash in lieu of fractional shares of Bank United
Corp. Class A common stock which such holder would otherwise have the right to
receive pursuant to the merger agreement. The Certificate shall then be
canceled.

      Upon the effective date, you will cease to have any rights as shareholder
of Texas Central. Until so surrendered, each Certificate will be deemed for all
corporate purposes to represent and evidence solely the right to receive the
merger consideration to be paid pursuant to the merger agreement. Neither the
Exchange Agent nor any other party will be liable to any holder of Certificates
for any amount paid to a public official pursuant to any applicable abandoned
property, escheat or similar law. Except as required by law, no interest will be
paid on the cash payable for fractional shares or the cash payable for
dissenting shares, and no dividends will be disbursed with respect to shares of
Bank United Corp. Class A common stock until certificates representing shares of
Texas Central stock are surrendered in exchange therefor. You will receive your

                                       -32-

share of the merger consideration only upon the Exchange Agent's receipt of a
lost certificate affidavit and an indemnity agreement in a form acceptable to
Bank United Corp.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

      The following discussion is a general summary of certain United States
federal income tax consequences of the merger. This discussion is based upon the
Code, regulations promulgated by the United States Treasury Department, judicial
authorities, and current rulings and administrative practice of the Internal
Revenue Service in each case as in effect as of the date hereof and all of which
are subject to change at any time, possibly with retroactive effect. For
purposes of this discussion, it is assumed that shares of Texas Central stock
are held as "capital assets" within the meaning of Section 1221 of the Code
(I.E., property held for investment). This discussion does not address all
aspects of federal income taxation that might be relevant to particular holders
of Texas Central stock in light of their status or personal investment
circumstances; nor does it discuss the consequences to such holders who are
subject to special treatment under the federal income tax laws such as foreign
persons, dealers in securities, regulated investment companies, life insurance
companies, other financial institutions, tax-exempt organizations, pass-through
entities, taxpayers who hold Texas Central stock as part of a "straddle,"
"hedge" or "conversion transaction" or who have a "functional currency" other
than the United States dollar or to persons who have received their Texas
Central stock as compensation. Further, this discussion does not address the
state, local or foreign tax consequences of the merger.

      The merger is intended to qualify as a reorganization under Section
368(a)(1)(A) of the Code. It is a condition to the obligations of Bank United
Corp. and Texas Central to consummate the merger that Bank United Corp. and
Texas Central shall have received opinions from each of their counsel to the
effect that, for federal income tax purposes, (i) the merger will constitute a
reorganization within the meaning of Section 368(a)(1)(A) of the Code, (ii) no
gain or loss will be recognized by holders of Texas Central stock upon receipt
of Bank United Corp. Class A common stock except for cash received in lieu of
fractional shares, (iii) the aggregate tax basis of Bank United Corp. Class A
common stock received by a shareholder of Texas Central will be the same as the
aggregate basis of Texas Central stock surrendered in exchange therefore, and
(iv) the holding period of Bank United Corp. Class A common stock to be received
by each Texas Central shareholder will include the period during which the
shareholder held the Texas Central stock surrendered in exchange therefore,
provided that the Texas Central stock is held as a capital asset on the date of
the exchange. These opinions will be rendered in reliance upon certain
assumptions and representations made by officers and shareholders of Texas
Central and officers of Bank United Corp. and BUC Acquisition. An opinion of
counsel represents counsel's best legal judgment, but has no binding effect or
official status of any kind, and no assurance can be given that contrary
positions will not be taken by the IRS or a court considering the issues.
Neither Texas Central nor Bank United Corp. has requested or will receive a
ruling from the IRS as to the tax consequences of the merger.

      Assuming the merger is treated as a reorganization within the meaning of
Section 368(a)(1)(A) of the Code, the merger will result in the following
federal income tax consequences to the Texas Central shareholders:

      o     No gain or loss upon the exchange of their Texas Central stock in
            the merger solely for Bank United Corp. Class A common stock, but
            gain or loss will be recognized by a shareholder on the receipt of
            cash instead of fractional shares.

      o     A shareholder's aggregate tax basis in the shares of Bank United
            Corp. Class A common stock received pursuant to the merger in
            exchange for Texas Central stock will be equal to the aggregate tax
            basis of the shares of Texas Central stock surrendered in exchange
            therefor (decreased by the amount of any tax basis allocable to
            fractional shares of Bank United Corp. Class A common stock for
            which cash is received).

      o     Each shareholder will include in his holding period for Bank United
            Corp. Class A common stock received in the merger the holding period
            of the shares of Texas Central stock surrendered in exchange
            therefor; provided that the Texas Central stock is held as a capital
            asset on the date of the exchange.

      o     A shareholder who receives cash in lieu of a fractional share
            interest in Bank United Corp. Class A common stock in the merger
            will be treated for federal income tax purposes as if the fractional
            share of

                                       -33-
<PAGE>
            Bank United Corp. Class A common stock had been received and then
            redeemed for cash and will recognize a capital gain or loss in an
            amount equal to the difference between the cash received and the
            proportionate part of the aggregate federal income tax basis of such
            shareholder's Texas Central stock allocable to such fractional share
            interest, unless such payment, under each such shareholder's
            particular facts and circumstances, is deemed to have the effect of
            a dividend distribution and not a redemption treated as an exchange
            under the principles of Section 302 of the Code.

      o     A shareholder who exercises the right to dissent in connection with
            the merger and receives only cash in exchange for such shareholder's
            Texas Central stock will be treated as having received such cash as
            a distribution in redemption of such shareholder's Texas Central
            stock and will recognize a capital gain or loss equal to the
            difference between the amount of cash received and the adjusted
            basis of such shareholder's Texas Central stock, unless such
            payment, under each such shareholder's particular facts and
            circumstances, is deemed to have the effect of a dividend
            distribution and not a redemption treated as an exchange under the
            principles of Section 302 of the Code.

      THE FOREGOING IS A SUMMARY DISCUSSION OF MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER. THE DISCUSSION IS INCLUDED FOR GENERAL INFORMATION
PURPOSES ONLY AND MAY NOT APPLY TO A PARTICULAR TEXAS CENTRAL SHAREHOLDER IN
LIGHT OF SUCH SHAREHOLDER'S PARTICULAR CIRCUMSTANCES. TEXAS CENTRAL SHAREHOLDERS
SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO
THEM OF THE MERGER, INCLUDING THE APPLICATION OF STATE, LOCAL AND FOREIGN TAX
LAWS AND POSSIBLE FUTURE CHANGES IN FEDERAL INCOME TAX LAWS AND THE
INTERPRETATION THEREOF, WHICH CAN HAVE RETROACTIVE EFFECTS.

DISSENTERS RIGHTS OF APPRAISAL AND RELATED ISSUES

      You have a statutory right to dissent from the merger by following the
specific procedures set forth below. If the merger is approved by the
shareholders and consummated, any shareholder who properly perfects his
dissenters' rights will be entitled to receive an amount of cash equal to the
fair value of his shares of Texas Central stock rather than being required to
receive the consideration established by the merger agreement. The following
summary is not a complete statement of the statutory dissenters' rights of
appraisal, and such summary is qualified by reference to the applicable
provisions of the Texas Business Corporation Act (the "TBCA"), which are
reproduced in full in Exhibit C to this Proxy Statement/Prospectus. YOU MUST
FOLLOW THE EXACT PROCEDURE REQUIRED BY THE TBCA IN ORDER TO PROPERLY EXERCISE
YOUR DISSENTER'S RIGHTS OF APPRAISAL AND AVOID WAIVER OF THOSE RIGHTS.

      Any shareholder who desires to dissent from the merger must file a written
objection to the merger with the Corporate Secretary of Texas Central, Ms.
Christiane Thompson, 8144 Walnut Hill Lane, Dallas, Texas 75231, prior to the
meeting. The written notice must state that the shareholder will exercise his
right to dissent if the merger is consummated and give the shareholder's address
to which notice of effectiveness of the merger should be sent. A VOTE AGAINST
THE MERGER IS NOT SUFFICIENT TO PERFECT A SHAREHOLDER'S STATUTORY RIGHT TO
DISSENT FROM THE MERGER. If the merger is consummated, each shareholder who sent
notice to Texas Central as described above and who did not vote in favor of the
merger will be deemed to have dissented from the merger (each a "Dissenting
Shareholder"). Failure to vote against the merger will not constitute a waiver
of the dissenters' rights of appraisal; on the other hand, a vote in favor of
the merger will constitute such a waiver.

      Bank United Corp. will be liable for any payments to Dissenting
Shareholders and, within ten days of the effective date, must notify the
Dissenting Shareholders in writing that the merger has occurred. Each Dissenting
Shareholder so notified must, within ten days of the delivery or mailing of such
notice, make a written demand on Bank United Corp., for payment of the fair
value of the Dissenting Shareholder's shares as estimated by the Dissenting
Shareholder. Failure to follow this procedure will constitute a waiver of his
dissenter's rights of appraisal by such Dissenting Shareholder. The demand shall
state the number and class of the shares owned by the Dissenting Shareholder and
the fair value of the shares as estimated by the Dissenting Shareholder. The
fair value of the shares shall be the value thereof as of the date immediately
preceding the meeting, excluding any appreciation or depreciation in
anticipation of the merger. Dissenting Shareholders who fail to make a written
demand within the ten day period will be bound by the merger and lose their
rights to dissent. Within twenty days after making a demand, the Dissenting
Shareholder must submit his or her Certificates to Bank United

                                       -34-
<PAGE>
Corp. for notation thereon that such demand has been made. Dissenting
Shareholders who have made a demand for payment of their shares shall not
thereafter be entitled to vote or exercise any other rights of a shareholder
except the right to receive payment for their shares pursuant to the provisions
of the TBCA and the right to maintain an appropriate action to obtain relief on
the basis of fraud.

      Within twenty days after receipt of a Dissenting Shareholder's demand
letter as described above, Bank United Corp. shall deliver or mail to the
Dissenting Shareholder written notice stating that Bank United Corp. accepts the
amount claimed in the demand letter and agrees to pay that amount, within ninety
days after the effective date, upon surrender of the Certificates duly endorsed
by the Dissenting Shareholder, or containing Bank United Corp.'s written
estimate of the fair value of the shares of Texas Central stock together with an
offer to pay such amount within ninety days after the effective date if Bank
United Corp. receives notice, within sixty days after the effective date,
stating that the Dissenting Shareholder agrees to accept that amount and upon
surrender of the Certificates duly endorsed by the Dissenting Shareholder. In
either case, the Dissenting Shareholder shall cease to have any ownership
interest in Texas Central following consummation of the merger.

      If the Dissenting Shareholder and Bank United Corp. cannot agree on the
fair value of the shares within sixty days after the effective date, the
Dissenting Shareholder may, within sixty days of the expiration of the initial
sixty day period, file a petition ("Petition") in any court of competent
jurisdiction in Harris County, Texas requesting a finding and determination of
the fair value of the Dissenting Shareholder's shares. Each Dissenting
Shareholder is not required to file a separate Petition. If one Dissenting
Shareholder files a Petition, Bank United Corp. must file, with the clerk of the
court in which the Petition was filed, a list containing the names and addresses
of the Dissenting Shareholders with whom agreements as to the value of their
shares have not been reached. The court will give notice of the time and place
of the hearing on the Petition to the Dissenting Shareholders named on the list.
Dissenting Shareholders so notified by the court will be bound by the final
judgment of the court regarding fair value of the shares. If no Petition is
filed within the appropriate time period, then all Dissenting Shareholders who
have not reached an agreement with Bank United Corp. on the value of their
shares shall be bound by the merger and lose their rights to dissent.

      After a hearing concerning the Petition, the court shall determine which
Dissenting Shareholders have complied with the provisions of the TBCA and have
become entitled to the valuation of, and payment for, their shares, and shall
appoint one or more qualified appraisers to determine the value of the shares of
Texas Central stock in question. The appraiser shall determine such value and
file a report with the court. The court shall then in its judgment determine the
fair value of the shares of Texas Central. The judgment of the court shall be
binding on Bank United Corp. and on all Dissenting Shareholders receiving notice
of the hearing. This value may be more than, less than, or equal to what is
received by non-Dissenting Shareholders. The court shall direct Bank United
Corp. to pay such amount, together with interest thereon beginning 91 days after
the effective date to the date of judgment, to the Dissenting Shareholders
entitled thereto. The judgment shall be payable upon the surrender to Bank
United Corp. of the Certificates fully endorsed by the Dissenting Shareholder.
Upon payment of the judgment, the Dissenting Shareholder shall cease to have any
interest in the Certificates. All court costs shall be allotted between the
Dissenting Shareholders and Bank United Corp. in the manner the court determines
to be fair and equitable.

      Any Dissenting Shareholder who has made a written demand on Bank United
Corp. for payment of the fair value of his Texas Central stock may withdraw such
demand at any time before payment for his shares has been made or before a
Petition has been filed with an appropriate court for determination of the fair
value of such shares. If a Dissenting Shareholder withdraws his demand, or if he
is otherwise unsuccessful in asserting his dissenters' rights of appraisal, such
Dissenting Shareholder shall be bound by the merger and his status as a former
shareholder shall be restored without prejudice to any corporate proceedings,
dividends, or distributions which may have occurred during the interim.

      In the absence of fraud in the transaction, a Dissenting Shareholder's
statutory right to appraisal is the exclusive remedy for the recovery of the
value of his shares or money damages to the Shareholder with respect to the
merger. See Exhibit C.

ACCOUNTING TREATMENT

      Bank United Corp. expects to account for the merger using the pooling of
interests method of accounting. Pursuant to the merger agreement, Bank United
Corp. will receive a letter from its independent accountants stating that the
merger will qualify as a pooling of interests, and Bank United Corp. will also
receive a letter from the independent accountants for Texas Central stating that
it knows of no reason why the merger would not qualify for pooling of interest
accounting treatment. With pooling of interests accounting treatment, assets and
liabilities are recorded at their book value as they existed on the books of
Texas Central at the time of the merger (i.e., goodwill is not recorded). The
results of operations for Bank United Corp. will not be restated to include the
results of operations of Texas Central prior to the effective date of the
merger, as the pre-merger results of operations for Texas Central are not deemed
to be material.

RESTRICTIONS ON SALES OF BANK UNITED CORP. CLASS A COMMON STOCK BY AFFILIATES OF
TEXAS CENTRAL

      Bank United Corp. has registered under the federal securities laws the
shares of its Class A common stock to be issued in the merger. Therefore, you
may sell such shares without restriction unless you are considered an
"affiliate" (as that term is used in the securities laws) of Texas Central or
you become an affiliate of Bank United Corp.

      If you are considered an affiliate of Texas Central or become an affiliate
of Bank United Corp., you may resell the shares of Bank United Corp. Class A
common stock only pursuant to an effective registration statement under the
securities laws, or pursuant to Rule 145 of the Commission's rules, or in
transactions otherwise exempt from registration under the securities laws. Bank
United Corp. is not obligated and does not intend to register for resale the
shares issued to affiliates of Texas Central. In addition, the Commission's
rules governing pooling of interests accounting prohibit resales by affiliates
of Texas Central of the Bank United Corp. Class A common stock until such time
as financial results covering at least 30 days of combined operations of Texas
Central and Bank United Corp. have been published .

      Each affiliate of Texas Central has signed a written agreement restricting
the transfer of shares of Bank United Corp. common stock received in the merger
to transfers permitted by the federal securities laws and the Commission's rules
relating to pooling of interests accounting.

REGULATORY APPROVALS

      The merger must be approved by the Office of Thrift Supervision and the
Federal Reserve Bank of Dallas must waive a filing of any application that may
otherwise be required to be filed with the Board of Governors of the Federal
Reserve System ("Federal Reserve"). On May 19, 1999, Bank United Corp. filed an
application with the Office of Thrift Supervision to obtain prior approval of
the merger. On May 19, 1999, Bank United Corp. filed a waiver request with the
Federal Reserve Bank of Dallas to obtain a waiver of any application that might
otherwise be required to be filed with the Federal Reserve. The Federal Reserve
Bank of Dallas approved the waiver request on June 3, 1999.

                        COMPARISON OF RIGHTS OF SHAREHOLDERS
                       OF BANK UNITED CORP. AND TEXAS CENTRAL

      The rights of Texas Central shareholders under Texas corporate law, and
the Articles of Incorporation and Bylaws of Texas Central will differ in some
respects from the rights Texas Central shareholders will have as shareholders of
Bank United Corp. under Delaware corporate law and the Certificate of
Incorporation and Bylaws of Bank United Corp. Bank United Corp.'s Certificate of
Incorporation and Bylaws contain several provisions which may make Bank United
Corp. a less attractive target for an acquisition of control by anyone who does
not have the support of the Bank United Corp. Board of Directors. Such
provisions include a classified board of directors, a restriction on a
shareholder's ability to call a special meeting of shareholders, the requirement
of a supermajority vote of shareholders to amend certain provisions of the
Certificate of Incorporation and Bylaws and the limitation that shareholder
action without a meeting may only be taken by unanimous written consent. Copies
of Bank United Corp.'s Certificate of Incorporation and Bylaws are available
upon written request from Bank United Corp. Copies of the Texas Central Articles
of Incorporation and Bylaws are available upon written request from Texas
Central.

(1)   The variances between March 31, 1999 and March 31, 1998 can be attributed
      to the opening of the Park Cities branch location in May 1998.

(2)   The variance for 1995 is attributed to a single credit charged off during
      that year. The subsequent year received a partial recovery of this
      charge-off.

(3)   The loss during 1997 is attributed to the sale of a mutual fund.

(4)   Texas Central elected S corporation status effective January 1, 1998.

(5)   Distributions made to shareholders during 1998 were for the payment of tax
      liability associated with the income passed through to them due to the
      Texas Central's S corporation election.

(6)   Return on average assets is net income, divided by average total assets.

(7)   Net operating expense ratio is total non-interest expense, less total
      non-interest income, as a percentage of average assets for each period.

(8)   Efficiency ratio is non-interest expense, divided by net interest income
      plus non-interest income.

(9)   When appropriate, certain ratios for the interim periods have been
      annualized.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS
                     AND RESULTS OF OPERATIONS OF TEXAS CENTRAL


      Management's Discussion and Analysis of Financial Condition and Results of
Operations of Texas Central analyzes the major elements of Texas Central's
balance sheets and statements of operations. This section should be read in
conjunction with Texas Central's consolidated financial statements and notes to
consolidated financial statements presented elsewhere in this Proxy
Statement/Prospectus.

RESULTS OF OPERATIONS

GENERAL

      The earnings of Texas Central depend primarily on net interest income
(i.e., the difference between the income earned on loans and investments and the
interest paid on its deposits and other borrowed funds.) Among the factors
affecting net interest income are the type and volume of its loans, deposits and
other borrowed funds, and the relative sensitivity of its interest-earning
assets and its interest-bearing liabilities to changes in market interest rates.

      Texas Central's income is also affected by fees it receives from other
banking services, by its provision for loan losses and by the level of its
operating expenses. All aspects of Texas Central's operations are affected by
general market, economic and competitive conditions.

      Texas Central reported net income of $357,000 for the three month period
ended March 31, 1999, an increase of $156,000 from net income of $201,000 for
the three month period ended March 31, 1998. Since January 1, 1998, Texas
Central has been an S corporation for federal income tax purposes. As an S
corporation, Texas Central is generally treated as a pass-through entity for
federal income tax purposes, such that it does not typically pay federal income
tax on its earnings. Except as otherwise noted, financial statements and
information for Texas Central for periods after January 1, 1998 contained in
this Proxy Statement/Prospectus do not include accruals or adjustments for the
federal income tax Texas Central would have incurred if it had not been an S
corporation.

      Texas Central reported net income of $1.3 million for the year ended
December 31, 1998, an increase of $367,000 from net income of $945,000 for the
year ended December 31, 1997. Income before income taxes was $1.5 million for
the year ended December 31, 1998, a $207,000 increase from the $1.2 million
earned during the year ended December 31, 1997. Texas Central had net income of
$735,000 and pre-tax income of $1.0 million for the year ended December 31,
1996. Changes occurring in the major components of Texas Central's income
statement for such periods are discussed below.

NET INTEREST INCOME

      Net interest income is the primary source of income for Texas Central and
represents the amount by which interest generated by earning assets exceeds the
cost of funds, primarily interest paid to depositors on interest-bearing
accounts.

                                       -45-
<PAGE>
      Net interest income was $1.2 million for the three months ended March 31,
1999, a 20.00% increase from net interest income of $1.0 million for the three
months ended March 31, 1998. The increase in net interest income is primarily
due to the increases in the volume of loans and investment securities. Average
rates earned on loans decreased to 9.11% as of March 31, 1999 from 9.53% as of
March 31, 1998. This decrease is primarily due to the drop in the prime rate
during the later part of 1998. Average deposits for the three months ended March
31, 1999, were $96.4 million an increase of 28.04% over average deposits of
$75.3 million for 1998.

      Net interest income was $4.7 million for the year ended December 31, 1998,
a 19.03% increase from net interest income of $3.9 million for the year ended
December 31, 1997. The increase in net interest income resulted primarily from
the increase in interest on securities and loans due to an increase in volume.
Average rates earned on interest-bearing assets decreased to 8.46% for the year
ended December 31, 1998 from 8.77% for the year ended December 31, 1997. Average
loans of $57.7 million for the year ended December 31, 1998, increased 22.55%
from average loans of $47.1 million for 1997. The increase in average loans
primarily resulted from increases in commercial and real estate loans, with a
slight increase in installment loans. Average deposits for the year ended
December 31, 1998 were $82.1 million an increase of 26.78% over average deposits
of $64.8 million for 1997.

      Net interest income was $3.9 million for the year ended December 31, 1997,
a 24.37% increase from net interest income of $3.2 million for 1996. The
increase in net interest income was due primarily to the increase in average
loans outstanding. Average loans of $47.1 million for the year ended December
31, 1997 increased 25.45% over average loans of $37.5 million for 1996. The
increase in average loans outstanding was the result of increases in commercial
and real estate loans during 1997. Average deposits for the year ended December
31, 1997 were $64.8 million an increase of 22.28% from average deposits of $53.0
million for the same period in 1996.

      The following tables set forth for the periods indicated an analysis of
net interest income by each major category of interest-earning assets and
interest-bearing liabilities. The table presents the total dollar amount of
average balances, interest income from average interest-earning assets and the
resultant yields, as well as interest expense on average interest-bearing
liabilities, expressed both in dollars and annualized rates.

PROVISION FOR CREDIT LOSSES

      Texas Central's allowance for credit losses is established through charges
to operating income in the form of the provision for credit losses. Actual
credit losses or recoveries of credit losses are charged or credited directly to
the allowance for credit losses.

      Texas Central recorded a provision for credit losses for the three months
ended March 31, 1999 of $84,000 compared to none taken during this same time
period for 1998. The allowance for credit losses expressed as a percentage of
outstanding loans was 0.84% and 0.97% as of March 31, 1999 and March 31, 1998,
respectively.

                                       -49-
<PAGE>
      For the years ended December 31, 1998 and December 31, 1997, Texas Central
recorded no provision for credit losses as the allowance was deemed adequate.
For the year ended December 31, 1996, Texas Central recorded a provision for
credit losses of $20,000. The allowance for credit losses as of December 31,
1998, 1997, and 1996 was $476,000, $549,000, and $544,000, respectively. The
allowance for credit losses expressed as a percentage of outstanding loans was
0.74%, 1.06%, and 1.21% as of December 31, 1998, 1997, and 1996, respectively.

      Nonaccrual loans were $198,000 as of March 31, 1999 and $54,000 as of
December 31, 1998.

NON-INTEREST INCOME

      Non-interest income, which primarily includes service charges and other
fee income was $193,000 for the three months ended March 31, 1999 and $161,000
for the three months ended March 1, 1998.

      Non-interest income increased 25.17% to $716,000 for the year ended
December 31, 1998 from $572,000 for the year ended December 31, 1997 primarily
due to growth in number of deposit accounts yielding service charge income and a
$123,000 loss on the sale of securities occurring in 1997.

      Non-interest income decreased 5.92% from $608,000 for the year ended
December 31, 1996 to $572,000 for the year ended December 31, 1997. The net
decrease was due primarily to the loss on sale of securities during 1997.

NON-INTEREST EXPENSE

      Non-interest expense includes expenses that Texas Central incurs in the
course of operations, such as employee compensation and benefits, occupancy
expense and general operating expenses. These expenses increased 10.40% from
$875,000 for the three months ended March 31, 1998 to $966,000 for the three
months ended March 31, 1999. The increase was due to primarily expenses related
to a branch which opened in May 1998, and salary and related benefits increases.

      Non-interest expense increased from $3.3 million for the year ended
December 31, 1997 to $3.9 million for the year ended December 31, 1998. The
increase was mainly attributable to an increase in salaries and employee
benefits and occupancy expense.

      Non-interest expense for the year ended December 31, 1997 increased by
$521,000, from the year ended December 31, 1996 due primarily to increased
salary and benefit costs.

FEDERAL AND STATE INCOME TAXES

      Texas Central's provision for income taxes was $11,000 and $126,000 for
the three month periods ended March 31, 1999 and 1998, respectively. As of
January 1, 1998, Texas Central elected S corporation status, therefore Texas
Central is not generally subject to a company-level federal income tax, and the
shareholders of Texas Central are taxed on their proportionate share of Texas
Central's taxable income. Due to the S corporation election, Texas Central had
to charge-off deferred tax assets of $52,000 and accrue for unrealized "net
built in gains" of $74,000 in the first quarter of 1998.

      Texas Central's provision for income taxes were $140,000, $300,000, and
$278,000 for the years ended December 31, 1998, 1997, and 1996, respectively.

DISCUSSION OF CHANGES IN FINANCIAL CONDITION

GENERAL

      From December 31, 1998 to March 31, 1999, Texas Central increased its
total assets by approximately $4.5 million primarily through growth in loans and
securities. These increases were funded by approximately $4.2 million of deposit
growth. From December 31, 1997 to 1998, total assets increased by approximately
$28.7 million as Texas Central opened a new branch and continued its growth in
existing markets.

      The accrual of interest on a loan is discontinued when the borrower's
financial condition is such that the collection of interest is doubtful. This
determination is the opinion of management based upon such criteria as default
in payment,

                                       -51-

asset deterioration, decline in cash flow, recurring operating loss, declining
sales, bankruptcy and other financial conditions which could result in default.

      Placing a loan on nonaccrual status has a two-fold impact on net interest
income. First, it causes an immediate charge against earnings with respect to
that particular loan. Second, it eliminates future interest earnings with
respect to that particular loan. Interest on such loans is not recognized until
the entire principal is collected or until the loan is returned to a performing
status.

ALLOWANCE FOR CREDIT LOSSES AND RISK ELEMENTS

      The provision for credit losses represents a determination by Texas
Central's management of the amount necessary to be charged to operating income
and transferred to the allowance for credit losses to maintain a level which it
considers adequate in relation to the risk of losses inherent in the loan
portfolio. It is Texas Central's policy to provide for exposure to losses of
specifically identified credits, and a general allowance for the remainder of
the loan portfolio. It is also Texas Central's policy to charge off in the
current period those loans in which a loss is deemed to exist.

      In assessing the adequacy of its allowance for credit losses, management
relies predominantly on its ongoing review of the loan portfolio, which is
undertaken both to ascertain whether there are probable losses which must be
charged off and to assess the risk characteristic of individually significant
loans and of the portfolio in the aggregate.

      The following table presents for the periods indicated an analysis of the
allowance for credit losses and other related data:

MARKET RISK ANALYSIS

      Market risk is the risk of loss from adverse changes in market prices and
interest rates. Texas Central's principal market risk exposure is to changes in
interest rates. Interest rate risk arises primarily from differences in the
duration or repricing of Texas Central's assets, liabilities, and financial
instruments with off-balance-sheet risk. Management actively monitors and
manages its interest rate risk exposure. This effort is accomplished through
structuring the balance sheet portfolio by seeking to maximize net interest
income while maintaining an acceptable level of risk to changes in market
interest rates. The achievement of this goal requires a balance between
profitability, liquidity and interest rate risk.

ASSET, LIABILITY AND FUNDS MANAGEMENT

      Texas Central's Asset Liability and Funds Management Policy provides
management with the necessary guidelines for effective funds management, and
Texas Central has established a measurement system for monitoring its net
interest rate sensitivity position. Texas Central manages its sensitivity
position within established guidelines.

      Interest rate risk is managed by the Asset Liability Committee ("ALCO"),
which is composed of senior officers of Texas Central Bank, in accordance with
policies approved by Texas Central Bank's Board of Directors. The ALCO
formulates strategies based on appropriate levels of interest rate risk. In
determining the appropriate level of interest rate risk, the ALCO considers the
impact on earnings and capital of the current outlook on interest rates,
potential changes in interest rates, regional economics, liquidity, business
strategies and other factors. The ALCO meets regularly to review, among other
things, the sensitivity of assets and liabilities to interest rate changes, the
book and market values of assets and liabilities, unrealized gains and losses,
purchase and sale activities, commitments to originate loans and the maturities
of

                                       -55-
<PAGE>
investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow
flexibility, maturities, deposits and consumer and commercial deposit activity.
Management uses two methodologies to manage interest rate risks: an analysis of
relationships between interest-earning assets and interest-bearing liabilities
and an interest rate shock simulation model. Texas Central has traditionally
managed its business to reduce its overall exposure to changes in interest
rates.

      Texas Central manages its exposure to interest rates by structuring its
balance sheet in the ordinary course of business. Texas Central does not enter
into instruments such as leveraged derivatives, interest rate swaps, financial
options, financial future contracts or forward delivery contracts for the
purpose of reducing interest rate risk.

      An interest rate sensitive asset or liability is one that, within a
defined time period, either matures or experiences an interest rate change in
line with general market interest rates. The management of interest rate risk is
performed by analyzing the maturity and repricing relationships between
interest-earning assets and interest-bearing liabilities at specific points in
time ("GAP") and by analyzing the effects of interest rate changes on net
interest income over specific periods of time by projecting the performance of
the mix of assets and liabilities in varied interest rate environments. Interest
rate sensitivity reflects the potential effect on net interest income of a
movement in interest rates. A company is considered to be asset sensitive, or
having a positive GAP, when the amount of its interest-earning assets maturing
or repricing within a given period exceeds the amount of its interest bearing
liabilities also maturing or repricing within that time period. Conversely, a
company is considered to be liability sensitive, or having a negative GAP, when
the amount of its interest-bearing liabilities maturing or repricing within a
given period exceeds the amount of its interest-earning assets also maturing or
repricing within that time period. During a period of rising interest rates, a
negative GAP would tend to affect net interest income adversely, while a
positive GAP would tend to result in an increase in net interest income. During
a period of falling interest rates, a negative GAP would tend to result in an
increase in net interest income, while a positive GAP would tend to affect net
interest income adversely.

LIQUIDITY

      Texas Central's asset and liability management policy is intended to
maintain adequate liquidity and thereby enhance its ability to raise funds to
support asset growth, meet deposit withdrawals and lending needs, maintain
reserve requirements, and otherwise sustain operations. Texas Central
accomplishes this through management of the maturities of its interest-earning
assets and interest-bearing liabilities. Liquidity is monitored and overall
interest rate risk is assessed through reports showing both sensitivity ratios
and existing dollar "GAP" data. Texas Central believes its present position to
be more than adequate to meet its current and future liquidity needs.

      The liquidity of Texas Central is maintained in the form of readily
marketable investment securities, demand deposits with commercial banks, vault
cash and federal funds sold. While the minimum liquidity requirements for banks
is determined by federal bank regulatory agencies as a percentage of deposit
liabilities, Texas Central's management monitors liquidity requirements as
warranted by interest rate trends, changes in the economy and the scheduled
maturity and interest rate sensitivity of the investment and loan portfolio,
deposits and anticipated loan fundings. In addition to the liquidity provided by
the foregoing, Texas Central has correspondent relationships as of March 31,
1999 with other institutions with available unsecured lines of credit to
purchase overnight funds totaling greater than $3.0 million should additional
liquidity be needed.

INTEREST RATE SENSITIVITY

      Interest rate sensitivity refers to the relationship between market
interest rates and net interest income resulting from the repricing of certain
assets and liabilities. Interest rate risk arises when an earning asset matures
or when its rate of interest changes in a time frame different from that of the
supporting interest-bearing liability. One way to reduce the risk of significant
adverse effects of market rate fluctuations on net interest income is to
minimize the difference between rate sensitive assets and liabilities, referred
to as "GAP," by maintaining a similar interest rate sensitivity position of the
assets and liabilities within a particular time frame.

      Maintaining an equilibrium between rate sensitive assets and liabilities
will reduce some of the risk associated with changes in market rates, but it
will not guarantee a stable net interest spread because yields and rates may
change

                                       -56-
<PAGE>
simultaneously and by different amounts. These changes in market spreads could
materially affect the overall net interest spread even if assets and liabilities
were perfectly matched.

      The following table sets forth an interest rate sensitivity analysis for
Texas Central as of March 31, 1999.

      Varying interest rate environments can create unexpected changes in
prepayment levels of assets and liabilities, which are not reflected in the
interest sensitivity analysis. These prepayments may have significant effects on
Texas Central's net interest margin. Because of these factors, an interest
sensitivity GAP report may not provide a complete assessment of Texas Central's
exposure to changes in interest rates.

      The following table presents an analysis of the percentage changes
inherent in Texas Central's net interest income over a 12 month period and
market value of portfolio equity arising from hypothetical changes in market
interest rates ("MVE"). MVE is the market value of assets, less the market value
of liabilities. The interest rate scenarios presented in the table include
interest rates at March 31, 1999, December 31, 1998 and December 31, 1997 and as
adjusted by instantaneous parallel rate changes upward and downward of up to 200
basis points. These scenarios are not comparable due to differences in the
interest rate environments, including the absolute level of rates and the shape
of the yield curve.

      The MVE is negatively impacted by the estimated effect of prepayments on
the value of mortgage-backed securities as rates decline. Further, this analysis
is based on Texas Central's interest rate exposure at the dates indicated and
does not contemplate any actions Texas Central might undertake in response to
changes in market interest rates, which could impact MVE.

      Each rate scenario shows unique prepayment, repricing, and reinvestment
assumptions. Management derived these assumptions considering published market
prepayment expectations, the repricing characteristics of individual instruments
or groups of similar instruments, Texas Central's historical experience, and
Texas Central's assets and liability management strategy. Further this analysis
assumes that certain of Texas Central's instruments would not be affected by the
changes in interest rates or would be partially affected due to the
characteristics of the instruments.

      There are limitations inherent in any methodology used to estimate the
exposure to changes in market interest rates. It is not possible to fully model
the market risk instruments with leverage, option or prepayment risks. Also,
Texas Central is affected by basis risk, which is the difference in repricing
characteristics of similar term rate indices. As such, this analysis is not
intended to be a forecast of the effect of a change in market interest rates on
Texas Central.

CAPITAL RESOURCES

      Capital resources are subject to various regulatory capital requirements
administered by the federal banking agencies. Any institution that fails to meet
its minimum capital requirements is subject to actions by regulators that could
have a direct material effect on the financial statements. Under the capital
adequacy guidelines and the regulatory framework for prompt corrective action,
Texas Central Bank must meet specific capital requirements based on its assets,
liabilities and certain off-balance sheet items as calculated under regulatory
accounting practices.

      To meet the capital adequacy requirements, Texas Central Bank must
maintain minimum ratios as defined in the regulations. Management believes that
as of March 31, 1999 and December 31, 1998, Texas Central Bank met all capital
adequacy requirements. As of March 31, 1999, Texas Central Bank satisfied the
requirements of a "well capitalized" institution for federal capital adequacy
purposes. Additionally, the Federal Reserve has capital adequacy requirements
for bank holding companies. For bank holding companies with consolidated assets
of less than $150 million, like Texas Central, these capital adequacy
requirements are applied on a bank-only basis.

      The following is a summary of Texas Central Bank's capitalization at March
31, 1999 and December 31, 1998 and 1997.

YEAR 2000 COMPLIANCE

      GENERAL. The Year 2000 risk involves computer programs and computer
software that are not able to perform without interruption into the Year 2000.
If computer systems do not correctly recognize the date change from December 31,
1999 to January 1, 2000, computer applications that rely on the date field could
fail or create erroneous results. Such erroneous results could affect interest,
payment or due dates or cause the temporary inability to process

                                       -58-
<PAGE>
transactions, send invoices or engage in similar normal business activities. If
these issues are not addressed by Texas Central, its suppliers and its
borrowers, there could be a material adverse impact on Texas Central's financial
condition or results of operations.

      STATE OF READINESS. Texas Central formally initiated its Year 2000 project
and plan in June 1997 to insure that its operational and financial systems will
not be adversely affected by Year 2000 problems. Texas Central has formed a Year
2000 project team and the Board of Directors and management are supporting all
compliance efforts and allocating the necessary resources to ensure completion.
An inventory of all systems and products (including both information technology
("IT") and non-information technology ("non-IT" systems) that could be affected
by the year 2000 date change has been developed, verified and categorized as to
its importance to Texas Central and an assessment of all major IT and critical
non-IT systems has been completed. This assessment involved inputting into IT
systems test data which simulates the Year 2000 date change and reviewing the
system output for accuracy. Texas Central's assessment of critical non-IT
systems involved reviewing such systems to determine whether they were date
dependent. Based on such assessment, Texas Central believes that none of its
critical non-IT systems are date dependent. The software for Texas Central's
systems is provided through service bureaus and software vendors. Texas Central
has contacted all of its third party vendors and software providers and is
requiring them to demonstrate and represent that the products provided are or
will be Year 2000 compliant and has planned a program of testing compliance.
Texas Central's service bureau, which performs substantially all of Texas
Central's data processing functions, has warranted in writing that its software
is Year 2000 compliant, and pursuant to applicable regulatory guidelines, Texas
Central is currently reviewing the results of user group tests performed by the
service provider to verify this assertion.

      Texas Central has completed the following phases of its Year 2000 plan:
(i) recognizing Year 2000 issues, (ii) assessing the impact of Year 2000 issues
on Texas Central's critical systems and (iii) upgrading systems as necessary to
resolve those Year 2000 issues which have been identified. Texas Central is in
the final stages of testing and implementing those systems that have been
upgraded.

      COSTS OF COMPLIANCE. Management does not expect the costs of bringing
Texas Central's systems into Year 2000 compliance will have a material adverse
effect on Texas Central's financial condition, results of operations or
liquidity. Texas Central has budgeted $75,000 to address Year 2000 issues and
$7,000 has been expended as of March 31, 1999. As of March 31, 1999, Texas
Central has not incurred any significant costs in relation to Year 2000. The
largest potential risk to Texas Central concerning Year 2000 is the malfunction
of its data processing system. In the event its data processing system does not
function properly, Texas Central believes it has developed adequate back-up
procedures. Texas Central believes it is in compliance with regulatory
guidelines regarding Year 2000 compliance, including the timetable for achieving
compliance.

      RISK RELATED TO THIRD PARTIES. The impact of Year 2000 noncompliance by
third parties with which Texas Central transacts business cannot be accurately
gauged. Texas Central identified its largest commercial loan ($100,000 or more)
customers and, based on information available to Texas Central, conducted a
preliminary evaluation to determine which of those customers are likely to be
affected by Year 2000 issues. Texas Central then surveyed those customers deemed
at risk to determine their readiness with respect to Year 2000 issues, plans to
address such issues and progress with respect to such plans. To the extent a
problem has been identified, Texas Central intends to monitor the customer's
progress in resolving such problem. In the event that Year 2000 noncompliance
adversely affects a borrower, Texas Central may be required to charge off the
loan to that borrower. Texas Central does not anticipate any significant losses
from its customers in regard to Year 2000 issues. Texas Central relies on the
Federal Reserve Bank of Dallas for electronic fund transfers and understands
that the systems of the Federal Reserve Bank of Dallas became Year 2000
compliant during the fourth quarter of 1998.

      CONTINGENCY PLAN. Texas Central has finalized its contingency planning
with respect to the Year 2000 date change and believes that if its own systems
should fail, Texas Central has adequate off-site capacity that could sustain
them through an interim period without significant losses. In the event that the
Federal Reserve Bank of Dallas is unable to handle electronic funds transfers,
Texas Central does not expect the impact to be material to its financial
condition or results of operations as long as Texas Central is able to utilize
an alternative electronic funds transfer source. As part of its contingency
planning, Texas Central has reviewed its loan customer base and the potential
impact on capital of Year 2000 non-compliance. In addition, Texas Central plans
to maintain additional cash on hand to meet any unusual deposit withdrawal
activity.

                                   TEXAS CENTRAL

GENERAL

      Texas Central was organized as a bank holding company for Texas Central
Bank in 1997. Texas Central Bank is an independent community bank that was
chartered in 1985. Texas Central offers a variety of services through Texas
Central Bank to satisfy the needs of the consumer and commercial customers in
its market area. The principal services offered by Texas Central include most
types of lending, including commercial, consumer and real estate loans. It also
offers safe deposit boxes, a night deposit facility, motor bank, wire transfer
and ATM cards. Since January 1, 1998, Texas Central has been an S corporation
for federal income tax purposes. As an S corporation, Texas Central is generally
treated as a pass-through entity for federal income tax purposes, such that it
does not typically pay federal income tax on its earnings. Financial statements
and information for periods after that date do not include accruals or
adjustments for the federal income tax Texas Central would have incurred had it
not been an S corporation. As of March 31, 1999, Texas Central had total assets
of $120.6 million, net loans of $65.4 million, total deposits of $100.2 million
and total shareholders' equity of $7.8 million.

FACILITIES

      Texas Central conducts business at full-service banking locations in
Dallas and Plano. Texas Central's headquarters are located at 8144 Walnut Hill
Lane, Dallas, Texas in space leased by Texas Central.

COMPETITION

      The banking business is highly competitive, and the profitability of Texas
Central depends principally on Texas Central's ability to compete in the market
areas in which its banking operations are located. Texas Central competes with
other commercial banks, savings banks, savings and loan associations, credit
unions, finance companies, mutual funds, insurance companies, brokerage and
investment banking firms, asset-based non-bank lenders and certain other
non-financial entities, including retail stores which may maintain their own
credit programs and certain governmental organizations which may offer more
favorable financing than Texas Central. Texas Central has been able to compete
effectively with other financial institutions by emphasizing customer service,
technology and local office decision-making; by establishing long-term customer
relationships and building customer loyalty; and by providing products and
services designed to address the specific needs of its customers.

EMPLOYEES

      As of March 31, 1999, Texas Central and Texas Central Bank had 38
full-time employees, seven of whom were executive officers of Texas Central
Bank. Texas Central Bank provides medical and hospitalization insurance to its
full-time employees. Texas Central Bank considers its relations with employees
to be excellent.

LEGAL PROCEEDINGS

      In the normal course of its businesses, Texas Central from time to time is
involved in legal proceedings. Other than such proceedings incidental to its
business, Texas Central's management is not aware of any pending or threatened
legal proceedings which, upon resolution, would have a material adverse effect
upon Texas Central's financial condition, results of operations or cash flows.
The continued absence of such proceedings is a condition to Bank United Corp.'s
obligation to consummate the merger.

              MARKET PRICES OF AND DISTRIBUTIONS ON TEXAS CENTRAL STOCK

      There has been no active public trading market for shares of Texas Central
stock, although it is traded infrequently in private transactions about which
Texas Central's management has little reliable information regarding price.

      The following table sets forth the dividends declared per share of Texas
Central stock for each period below.


                                                     TEXAS CENTRAL STOCK
1998                                                 -------------------
Fourth Quarter.......................................... $  .5075
Third Quarter...........................................    .4285
Second Quarter..........................................    .2760
First Quarter...........................................    .3521

No dividends were declared on Texas Central stock during the first quarter of
1999 or during 1997.

      Holders of Texas Central stock are entitled to receive distributions when,
as and if declared by Texas Central's Board of Directors out of funds legally
available therefor. While Texas Central has declared distributions on the Texas
Central stock since January of 1998, there is no assurance that Texas Central
will continue to pay distributions in the future. The merger agreement permits
Texas Central, between September 30, 1998 and the closing, to declare and pay
cash dividends in an amount equal to 39.6% of its taxable income as estimated by
Texas Central and approved by Bank United Corp. in good faith.

      The principal source of cash revenues to Texas Central is dividends paid
by Texas Central Bank with respect to Texas Central Bank's capital stock. There
are certain restrictions on the payment of such dividends imposed by federal and
state banking laws, regulations and authorities. As of March 31, 1999, an
aggregate of approximately $2.0 million was available for payment of dividends
by Texas Central Bank to Texas Central under applicable restrictions, without
regulatory approval. Regulatory authorities could impose administratively
stricter limitations on the ability of Texas Central Bank to pay dividends to
Texas Central if such limits were deemed appropriate to preserve certain capital
adequacy requirements.

      If the merger is not consummated, the future declaration and payment of
distributions on Texas Central stock will depend upon the earnings and financial
condition of Texas Central, liquidity and capital requirements, the general
economic and regulatory climate, Texas Central's ability to service any equity
or debt obligations senior to the Texas Central stock and other factors deemed
relevant by Texas Central's Board of Directors.

                     SUPERVISION AND REGULATION OF TEXAS CENTRAL


      The supervision and regulation of bank holding companies and their
subsidiaries is intended primarily for the protection of depositors, the deposit
insurance funds of the Federal Deposit Insurance Corporation ("FDIC") and the
banking system as a whole, and not for the protection of the bank holding
company shareholders or creditors. The banking agencies have broad enforcement
power over bank holding companies and banks including the power to impose
substantial fines and other penalties for violations of laws and regulations.

      The following description summarizes some of the laws to which Texas
Central and Texas Central Bank are subject. References herein to applicable
statutes and regulations are brief summaries thereof, do not purport to be
complete, and are qualified in their entirety by reference to such statutes and
regulations.

TEXAS CENTRAL

      Texas Central is a bank holding company registered under the Bank Holding
Company Act of 1956, as amended ("BHC Act"), and it is subject to supervision,
regulation and examination by the Federal Reserve. The BHC Act and other federal
laws subject bank holding companies to particular restrictions on the types of
activities in which they may engage, and to a range of supervisory requirements
and activities, including regulatory enforcement actions for violations of laws
and regulations.

      REGULATORY RESTRICTIONS ON DIVIDENDS; SOURCE OF STRENGTH. It is the policy
of the Federal Reserve that bank holding companies should pay cash dividends on
common stock only out of income available over the past year and only if
prospective earnings retention is consistent with the organization's expected
future needs and financial condition. The policy provides that bank holding
companies should not maintain a level of cash dividends that undermines the bank
holding company's ability to serve as a source of strength to its banking
subsidiaries.

      Under Federal Reserve policy, a bank holding company is expected to act as
a source of financial strength to each of its banking subsidiaries and commit
resources to their support. Such support may be required at times when, absent
this Federal Reserve policy, a holding company may not be inclined to provide
it. As discussed below, a bank holding company in certain circumstances could be
required to guarantee the capital plan of an undercapitalized banking
subsidiary.

      In the event of a bank holding company's bankruptcy under Chapter 11 of
the U.S. Bankruptcy Code, the trustee will be deemed to have assumed and is
required to cure immediately any deficit under any commitment by the debtor
holding company to any of the federal banking agencies to maintain the capital
of an insured depository institution, and any claim for breach of such
obligation will generally have priority over most other unsecured claims.

      ACTIVITIES "CLOSELY RELATED" TO BANKING. The BHC Act prohibits a bank
holding company, with certain limited exceptions, from acquiring direct or
indirect ownership or control of any voting shares of any company which is not a
bank or from engaging in any activities other than those of banking, managing or
controlling banks and certain other subsidiaries, or furnishing services to or
performing services for its subsidiaries. One principal exception to these
prohibitions allows the acquisition of interests in companies whose activities
are found by the Federal Reserve, by order or regulation, to be so closely
related to banking or managing or controlling banks, as to be a proper incident
thereto. Some of the activities that have been determined by regulation to be
closely related to banking are making or servicing loans, performing certain
data processing services, acting as an investment or financial advisor to
certain investment trusts and investment companies, and providing securities
brokerage services. Other activities approved by the Federal Reserve include
consumer financial counseling, tax planning and tax preparation, futures and
options advisory services, check guaranty services, collection agency and credit
bureau services, and personal property appraisals. In approving acquisitions by
bank holding companies of companies engaged in banking-related activities, the
Federal Reserve considers a number of factors, and weighs the expected benefits
to the public (such as greater convenience and increased competition or gains in
efficiency) against the risks of possible adverse effects (such as undue
concentration of resources, decreased or unfair competition, conflicts of
interest, or unsound banking practices). The Federal Reserve is also empowered
to differentiate between activities commenced de novo and activities commenced
through acquisition of a going concern.

                                       -63-

      SECURITIES ACTIVITIES. The Federal Reserve has approved applications by
bank holding companies to engage, through nonbank subsidiaries, in certain
securities-related activities (underwriting of municipal revenue bonds,
commercial paper, consumer receivable-related securities and one-to-four family
mortgage-backed securities), provided that the affiliates would not be
"principally engaged" in such activities for purposes of Section 20 of the
Glass-Steagall Act. In limited situations, holding companies may be able to use
such subsidiaries to underwrite and deal in corporate debt and equity
securities.

      SAFE AND SOUND BANKING PRACTICES. Bank holding companies are not permitted
to engage in unsafe and unsound banking practices. The Federal Reserve's
Regulation Y, for example, generally requires a holding company to give the
Federal Reserve prior notice of any redemption or repurchase of its own equity
securities, if the consideration to be paid, together with the consideration
paid for any repurchases or redemptions in the preceding year, is equal to 10%
or more of Texas Central's consolidated net worth. The Federal Reserve may
oppose the transaction if it believes that the transaction would constitute an
unsafe or unsound practice or would violate any law or regulation. Depending
upon the circumstances, the Federal Reserve could take the position that paying
a dividend would constitute an unsafe or unsound banking practice.

      The Federal Reserve has broad authority to prohibit activities of bank
holding companies and their nonbanking subsidiaries which represent unsafe and
unsound banking practices or which constitute violations of laws or regulations,
and can assess civil money penalties for certain activities conducted on a
knowing and reckless basis, if those activities caused a substantial loss to a
depository institution. The penalties can be as high as $1,000,000 for each day
the activity continues.

      ANTI-TYING RESTRICTIONS. Bank holding companies and their affiliates are
prohibited from tying the provision of certain services, such as extensions of
credit, to other services offered by a holding company or its affiliates.

      CAPITAL ADEQUACY REQUIREMENTS. The Federal Reserve has adopted a system
using risk-based capital guidelines to evaluate the capital adequacy of bank
holding companies. For bank holding companies with consolidated assets of less
than $150 million, like Texas Central, these capital adequacy requirements are
applied on a bank-only basis.

      IMPOSITION OF LIABILITY FOR UNDERCAPITALIZED SUBSIDIARIES. Bank regulators
are required to take "prompt corrective action" to resolve problems associated
with insured depository institutions whose capital declines below certain
levels. In the event an institution becomes "undercapitalized," it must submit a
capital restoration plan. The capital restoration plan will not be accepted by
the regulators unless each company having control of the undercapitalized
institution guarantees the subsidiary's compliance with the capital restoration
plan up to a certain specified amount. Any such guarantee from a depository
institution's holding company is entitled to a priority of payment in
bankruptcy.

      The aggregate liability of the holding company of an undercapitalized bank
is limited to the lesser of 5% of the institution's assets at the time it became
undercapitalized or the amount necessary to cause the institution to be
"adequately capitalized." The bank regulators have greater power in situations
where an institution becomes "significantly" or "critically" undercapitalized or
fails to submit a capital restoration plan. For example, a bank holding company
controlling such an institution can be required to obtain prior Federal Reserve
approval of proposed dividends, or might be required to consent to a merger or
to divest the troubled institution or other affiliates.

      ACQUISITIONS BY BANK HOLDING COMPANIES. The BHC Act requires every bank
holding company to obtain the prior approval of the Federal Reserve before it
may acquire all or substantially all of the assets of any bank, or ownership or
control of any voting shares of any bank, if after such acquisition it would own
or control, directly or indirectly, more than 5% of the voting shares of such
bank. In approving bank acquisitions by bank holding companies, the Federal
Reserve is required to consider the financial and managerial resources and
future prospects of the bank holding company and the banks concerned, the
convenience and needs of the communities to be served, and various competitive
factors.

      CONTROL ACQUISITIONS. The Change in Bank Control Act prohibits a person or
group of persons from acquiring "control" of a bank holding company unless the
Federal Reserve has been notified and has not objected to the transaction. Under
a rebuttal presumption established by the Federal Reserve, the acquisition of
10% or more of a class of voting stock of a bank holding company where such
person is the largest shareholder, would, under the circumstances set forth in
the presumption, constitute an acquisition of control.

                                       -64-
<PAGE>
      In addition, any company is required to obtain the approval of the Federal
Reserve under the BHC Act before acquiring 25% (5% in the case of an acquirer
that is a bank holding company) or more of the voting power of a bank holding
company, or otherwise obtaining control or a "controlling influence" over a bank
holding company.

TEXAS CENTRAL BANK

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

      RESTRICTIONS ON TRANSACTIONS WITH AFFILIATES AND INSIDERS. Transactions
between Texas Central Bank and its nonbanking subsidiaries, are subject to
Section 23A of the Federal Reserve Act. In general, Section 23A imposes limits
on the amount of such transactions, and also requires certain levels of
collateral for loans to affiliated parties. It also limits the amount of
advances to third parties which are collateralized by the securities or
obligations of Texas Central Bank or its subsidiaries.

      Affiliate transactions are also subject to Section 23B of the Federal
Reserve Act which generally requires that certain transactions between Texas
Central Bank and its affiliates be on terms substantially the same, or at least
as favorable to Texas Central Bank, as those prevailing at the time for
comparable transactions with or involving other nonaffiliated persons.

      The restrictions on loans to directors, executive officers, principal
shareholders and their related interests (collectively referred to herein as
"insiders") contained in the Federal Reserve Act and Regulation O apply to all
insured institutions and their subsidiaries and holding companies. These
restrictions include limits on loans to one borrower and conditions that must be
met before such a loan can be made. There is also an aggregate limitation on all
loans to insiders and their related interests. These loans cannot exceed the
institution's total unimpaired capital and surplus, and the OCC may determine
that a lesser amount is appropriate. Insiders are subject to enforcement actions
for knowingly accepting loans in violation of applicable restrictions.

      RESTRICTIONS ON DISTRIBUTION OF SUBSIDIARY BANK DIVIDENDS AND ASSETS.
Dividends paid by Texas Central Bank to Texas Central are Texas Central's
principal source of operating funds. Capital adequacy requirements serve to
limit the amount of dividends that may be paid by Texas Central Bank. Until
capital surplus equals or exceeds capital stock, a national bank must transfer
to surplus 10% of its net income for the preceding four quarters in the case of
an annual dividend or 10% of its net income for the preceding two quarters in
the case of a quarterly or semiannual dividend. At March 31, 1999, the Texas
Central Bank's capital surplus exceeded its capital stock. Without prior
approval, a national bank may not declare a dividend if the total amount of all
dividends, declared by the bank in any calendar year exceeds the total of the
bank's retained net income for the current year and retained net income for the
preceding two years. Under federal law, Texas Central Bank cannot pay a dividend
if, after paying the dividend, Texas Central Bank will be "undercapitalized."
The OCC may declare a dividend payment to be unsafe and unsound even though
Texas Central Bank would continue to meet its capital requirements after the
dividend.

      Because Texas Central is a legal entity separate and distinct from its
subsidiaries, its right to participate in the distribution of assets of any
subsidiary upon the subsidiary's liquidation or reorganization will be subject
to the prior claims of the subsidiary's creditors. In the event of a liquidation
or other resolution of an insured depository institution, the claims of
depositors and other general or subordinated creditors are entitled to a
priority of payment over the claims of holders of any obligations of the
institution to its shareholders, arising as a result of their status as
shareholders, including any depository institution holding company (such as
Texas Central) or any shareholder or creditor thereof.

      EXAMINATIONS. The OCC periodically examines and evaluates national banks.
Based upon such an evaluation, the OCC may revalue the assets of the institution
and require that it establish specific reserves to compensate for the difference
between the OCC-determined value and the book value of such assets.

                                       -65-
<PAGE>
      CAPITAL ADEQUACY REQUIREMENTS. The OCC has adopted regulations
establishing minimum requirements for the capital adequacy of national banks.
The OCC may establish higher minimum requirements if, for example, a bank has
previously received special attention or has a high susceptibility to interest
rate risk.

      The OCC's risk-based capital guidelines generally require national banks
to have a minimum ratio of Tier 1 capital to total risk-weighted assets of 4%
and a ratio of total capital to total risk-weighted assets of 8%. As of March
31, 1999, Texas Central Bank's ratio of Tier 1 capital to total risk-weighted
assets was 10.27% and its ratio of total capital to total risk-weighted assets
was 11.02%.

      The OCC's leverage guidelines require national banks to maintain Tier 1
capital of no less than 5% of average total assets, except in the case of
certain highly rated banks for which the requirement is 3% of average total
assets. As of March 31, 1999, Texas Central Bank's ratio of Tier 1 capital to
average total assets (leverage ratio) was 6.54%.

      CORRECTIVE MEASURES FOR CAPITAL DEFICIENCIES. The federal banking
regulators are required to take "prompt corrective action" with respect to
capital-deficient institutions. Agency regulations define, for each capital
category, the levels at which institutions are "well capitalized," "adequately
capitalized," "under capitalized," "significantly under capitalized" and
"critically under capitalized." A "well capitalized" bank has a total risk based
capital ratio of 10% or higher; a Tier 1 risk based capital ratio of 6% or
higher; a leverage ratio of 5% or higher; and is not subject to any written
agreement, order or directive requiring it to maintain a specific capital level
for any capital measure. An "adequately capitalized" bank has a total risk based
capital ratio of 8% or higher; a Tier 1 risk based capital ratio of 4% or
higher; a leverage ratio of 4% or higher (3% or higher if the bank was rated a
CAMEL 1 in its most recent examination report and is not experiencing
significant growth); and does not meet the criteria for a well capitalized bank.
A bank is "under capitalized" if it fails to meet any one of the ratios required
to be adequately capitalized.

      In addition to requiring undercapitalized institutions to submit a capital
restoration plan, agency regulations contain broad restrictions on certain
activities of undercapitalized institutions including asset growth,
acquisitions, branch establishment, and expansion into new lines of business.
With certain exceptions, an insured depository institution is prohibited from
making capital distributions, including dividends, and is prohibited from paying
management fees to control persons if the institution would be undercapitalized
after any such distribution or payment.

      As an institution's capital decreases, the OCC's enforcement powers become
more severe. A significantly undercapitalized institution is subject to mandated
capital raising activities, restrictions on interest rates paid and transactions
with affiliates, removal of management, and other restrictions. The OCC has only
very limited discretion in dealing with a critically undercapitalized
institution and is virtually required to appoint a receiver or conservator.

      Banks with risk-based capital and leverage ratios below the required
minimums may also be subject to certain administrative actions, including the
termination of deposit insurance upon notice and hearing, or a temporary
suspension of insurance without a hearing in the event the institution has no
tangible capital.

      DEPOSIT INSURANCE ASSESSMENTS. Texas Central must pay assessments to the
FDIC for federal deposit insurance protection. The FDIC has adopted a risk based
assessment system as required by FDICIA. Under this system, FDIC-insured
depository institutions pay insurance premiums at rates based on their risk
classification. Institutions assigned to higher-risk classifications (that is,
institutions that pose a greater risk of loss to their respective deposit
insurance funds) pay assessments at higher rates than institutions that pose a
lower risk. An institution's risk classification is assigned based on its
capital levels and the level of supervisory concern the institution poses to the
regulators. In addition, the FDIC can impose special assessments in certain
instances. The current range of BIF assessments is between 0% and .27% of
deposits.

      The FDIC established a process for raising or lowering all rates for
insured institutions semi-annually if conditions warrant a change. Under this
new system, the FDIC has the flexibility to adjust the assessment rate schedule
twice a year without seeking prior public comment, but only within a range of
five cents per $100 above or below the premium schedule adopted. Changes in the
rate schedule outside the five cent range above or below the current schedule
can be made by the FDIC only after a full rulemaking with opportunity for public
comment.

      On September 30, 1996, President Clinton signed into law an act that
contained a comprehensive approach to recapitalizing the Savings Association
Insurance Fund ("SAIF") and to assure the payment of the Financing Corporation's
("FICO") bond obligations. Under this new act, banks insured under the BIF are
required to pay a portion of the interest due on bonds that were issued by FICO
to help shore up the ailing Federal Savings and Loan Insurance Corporation in
1987. The BIF rate must equal one-fifth of the SAIF rate through year-end 1999,
or until the insurance funds are merged, whichever occurs first. Thereafter BIF
and SAIF payers will be assessed pro rata for the FICO bond obligations. With
regard to the assessment for the FICO obligation, the current BIF rate is .0126%
of deposits.

      ENFORCEMENT POWERS. The FDIC, OCC and the other federal banking agencies
have broad enforcement powers, including the power to terminate deposit
insurance, impose substantial fines and other civil and criminal penalties and
appoint a conservator or receiver. Failure to comply with applicable laws,
regulations and supervisory agreements could subject Texas Central Bank, as well
as officers, directors and other institution-affiliated parties of these
organizations, to administrative sanctions and potentially substantial civil
money penalties. The appropriate federal banking agency may appoint the FDIC as
conservator or receiver for a banking institution (or the FDIC may appoint
itself, under certain circumstances) if any one or more of a number of
circumstances exist, including, without limitation, the fact that the banking
institution is undercapitalized and has no reasonable prospect of becoming
adequately capitalized; fails to become adequately capitalized when required to
do so; fails to submit a timely and acceptable capital restoration plan; or
materially fails to implement an accepted capital restoration plan.

      CROSS-GUARANTEE PROVISIONS. The Financial Institutions Reform, Recovery
and Enforcement Act of 1989 ("FIRREA") contains a "cross-guarantee" provision
which generally makes commonly controlled insured depository institutions liable
to the FDIC for any losses incurred in connection with the failure of a commonly
controlled depository institution.

      COMMUNITY REINVESTMENT ACT. The Community Reinvestment Act of 1977 ("CRA")
and the regulations issued thereunder are intended to encourage banks to help
meet the credit needs of their service area, including low and moderate income
neighborhoods, consistent with the safe and sound operations of the banks. These
regulations also provide for regulatory assessment of a bank's record in meeting
the needs of its service area when considering applications to establish
branches, merger applications and applications to acquire the assets and assume
the liabilities of another bank. FIRREA requires federal banking agencies to
make public a rating of a bank's performance under the CRA. In the case of a
bank holding company, the CRA performance record of the banks involved in the
transaction are reviewed in connection with the filing of an application to
acquire ownership or control of shares or assets of a bank or to merge with any
other bank holding company. An unsatisfactory record can substantially delay or
block the transaction.

      CONSUMER LAWS AND REGULATIONS. In addition to the laws and regulations
discussed herein, Texas Central is also subject to certain consumer laws and
regulations that are designed to protect consumers in transactions with banks.
While the list set forth herein is not exhaustive, these laws and regulations
include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds
Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity
Act, and the Fair Housing Act, among others. These laws and regulations mandate
certain disclosure requirements and regulate the manner in which financial
institutions must deal with customers when taking deposits or making loans to
such customers. Texas Central must comply with the applicable provisions of
these consumer protection laws and regulations as part of their ongoing customer
relations.

INSTABILITY OF REGULATORY STRUCTURE

      Various legislation, including proposals to overhaul the bank regulatory
system, expand the powers of banking institutions and bank holding companies and
limit the investments that a depository institution may make with insured funds,
is from time to time introduced in Congress. Such legislation may change banking
statutes and the operating environment of Texas Central and Texas Central Bank
in substantial and unpredictable ways. Neither Texas Central nor Texas Central
Bank can determine the ultimate effect that potential legislation, if enacted,
or implementing regulations with respect thereto, would have upon the financial
condition or results of operations of Texas Central or Texas Central Bank.

<PAGE>
EXPANDING ENFORCEMENT AUTHORITY

      One of the major additional burdens imposed on the banking industry by
FDICIA is the increased ability of banking regulators to monitor the activities
of banks and their holding companies. In addition, the Federal Reserve, OCC, and
FDIC are possessed of extensive authority to police unsafe or unsound practices
and violations of applicable laws and regulations by depository institutions and
their holding companies. For example, the FDIC may terminate the deposit
insurance of any institution which it determines has engaged in an unsafe or
unsound practice. The agencies can also assess civil money penalties, issue
cease and desist or removal orders, seek injunctions, and publicly disclose such
actions. FDICIA, FIRREA and other laws have expanded the agencies' authority in
recent years, and the agencies have not yet fully tested the limits of their
powers.

EFFECT ON ECONOMIC ENVIRONMENT

      The policies of regulatory authorities, including the monetary policy of
the Federal Reserve, have a significant effect on the operating results of bank
holding companies and their subsidiaries. Among the means available to the
Federal Reserve to affect the money supply are open market operations in U.S.
Government securities, changes in the discount rate on member bank borrowings,
and changes in reserve requirements against member bank deposits. These means
are used in varying combinations to influence overall growth and distribution of
bank loans, investments and deposits, and their use may affect interest rates
charged on loans or paid for deposits.

      Federal Reserve monetary policies have materially affected the operating
results of commercial banks in the past and are expected to continue to do so in
the future. The nature of future monetary policies and the effect of such
policies on the business and earnings of Texas Central and Texas Central Bank
cannot be predicted.

The Board of Directors
Texas Central Bancshares, Inc. and Subsidiaries

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

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the 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
Central Bancshares, Inc. and Subsidiaries as of December 31, 1998 and 1997, the
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       DECEMBER 31, 1998, 1997, AND 1996

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of the significant accounting policies used by
Texas Central Bancshares, Inc. and Subsidiaries (together referred to as
Company) in the preparation of its consolidated financial statements. These
accounting policies conform to generally accepted accounting principles and
practices generally followed within the banking industry. A description of the
more significant of these policies follows.

  BASIS OF PRESENTATION

     The accompanying consolidated financial statements include the accounts of
Texas Central Bancshares, Inc. (TCBI) and its wholly-owned subsidiary, Texas
Central Bancshares of Delaware, Inc. (TCBD), and its wholly-owned subsidiary,
Texas Central Bank, N.A. (Bank) and its wholly-owned subsidiary CTL Leasing,
Inc. (CTL).

     During 1997, TCBI (a Texas corporation) and TCBD (a Delaware corporation)
were formed. In December 1997, a transaction was consummated whereby the
stockholders of the Bank effectively exchanged all of their outstanding shares
(305,440) for 285,740 shares of TCBI stock and cash of $492,500. Following the
consummation of this transaction the Bank is a wholly-owned subsidiary of the
Delaware company which in turn, is a wholly-owned subsidiary of TCBI. Because
the stockholder group both before and after the exchange were substantially the
same, the transaction was accounted for in a manner similar to a pooling of
interests.

     All material intercompany transactions and balances have been eliminated in
consolidation.

  USE OF ESTIMATES

     The accompanying consolidated financial statements and information as of
March 31, 1999 and for the three months ended March 31, 1999 and 1998 are
unaudited, and include all adjustments (consisting of only normal recurring
adjustments) that are necessary, in the opinion of management, for a fair
presentation. The results from operations for the periods ended March 31, 1999
and 1998 are not necessarily reflective of the annual results.

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     For the purposes of reporting cash flows, cash and cash equivalents include
cash on hand, amounts due from banks, other short term investments and federal
funds sold. All highly liquid investments with an initial maturity of less than
ninety days are considered to be cash equivalents.

  SECURITIES AVAILABLE FOR SALE

     Available for sale securities consist of bonds, notes, debentures, and
certain equity securities not classified as trading securities nor as held to
maturity securities.

     Unrealized holding gains and losses, net of tax, on available for sale
securities, are reported in other comprehensive income. Realized gains and
losses are included in other income or expense, and when applicable, are
reported as a reclassification adjustment, net of tax, in other comprehensive
income.

                                      F-8

                TEXAS CENTRAL BANCSHARES, INC. AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Declines in the fair value of individual held to maturity and available for
sale securities below their cost that are other than temporary, if any, would
result in write-downs of the individual securities to their fair value. The
related write-downs, if any, would be included in earnings as realized losses.

     Premiums and discounts are recognized in interest income using the interest
method over the period to maturity.

  SECURITIES HELD TO MATURITY

     Bonds, notes, and debentures for which the Company has the positive intent
and ability to hold to maturity are reported at cost, adjusted for premiums and
discounts that are recognized in interest income using the interest method over
the period to maturity.

  LOANS AND ALLOWANCE FOR POSSIBLE LOAN LOSSES

     Loans are stated net of loan participations sold without recourse,
allowance for possible loan losses and unearned income. Unearned income on
installment loans is taken into income over the term of the loan by the
sum-of-the-periodic-balances method. The effect of not using the interest method
is not material to the financial statements.

     Loans that management has the intent and ability to hold for the
foreseeable future or until maturity or pay-off are reported at their
outstanding principal balance adjusted for any charge-offs, the allowance for
loan losses, and unamortized premiums or discounts on purchased loans.

     Impaired loans (as defined by SFAS No. 114 and as amended by SFAS No. 118)
are accounted for at the net present value of expected future cash flows,
discounted at the loan's effective interest rate, the observable market price of
the loan, or at fair value of the collateral if the loan is collateral
dependent.

     The accrual of interest on impaired loans is discontinued when, in
management's opinion, the borrower may be unable to meet payments as they become
due. When accrual of interest is discontinued, all unpaid accrued interest is
reversed. Interest income is subsequently recognized only to the extent cash
payments are received in excess of principal due.

     The allowance for loan losses is increased by charges to income and
decreased by charge-offs (net of recoveries). Management's periodic evaluation
of the adequacy of the allowance is based on the Company's past loan loss
experience, known and inherent risks in the portfolio, adverse situations that
may affect the borrower's ability to repay, the estimated value of any
underlying collateral, and current economic conditions.

  FEES AND COSTS ASSOCIATED WITH ORIGINATING LOANS

     Fees and costs associated with originating loans are recognized in income
generally in the period in which the fees and costs were incurred. Under
generally accepted accounting principles such net fees or costs generally are
deferred and recognized over the life of the loan as an adjustment of yield.

     For the years ended December 31, 1998, 1997, and 1996, management believes
that not deferring such fees and costs and amortizing them over the life of the
related loans does not materially affect the financial position or results of
operations of the Company.

  BANK PREMISES AND EQUIPMENT

     Bank premises and furniture and equipment are carried at cost, less
accumulated depreciation and amortization. Depreciation is computed on the
straight-line method over the estimated useful life of each type of asset,
ranging from three to ten years.

                                      F-9
<PAGE>
                TEXAS CENTRAL BANCSHARES, INC. AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Maintenance and repairs are charged to expense; betterments and renewals
are capitalized. Upon retirement or replacement, the cost of the asset and the
related accumulated depreciation are eliminated with the resulting gain or loss
included in the consolidated statement of income.

  OTHER REAL ESTATE OWNED

     Real estate properties acquired through, or in lieu of loan, foreclosure
are to be sold and are initially recorded at fair value at the date of
foreclosure, establishing a new cost basis. After foreclosure, valuations are
periodically performed by management and the real estate is carried at the lower
of carrying amount or fair value less cost to sell. Revenue and expenses from
operations and changes in the valuation allowance are included in other
noninterest expense.

  INCOME TAXES

     The Company files a consolidated income tax return with its subsidiaries.
Federal income tax expense or benefit has been allocated on a separate return
basis.

     Effective January 1, 1998, the Company with the consent of its stockholders
elected to be an S corporation under the Internal Revenue Code (Code). In lieu
of corporate income taxes, the stockholders of an S corporation are taxed on
their proportionate share of the Company's taxable income. Following this
election the Company will generally report no federal income tax expense or
benefit in its financial statements, except for the expense incurred in
connection with "recognized net built in gains" (as defined in the Code).

     Prior to January 1, 1998, deferred tax assets and liabilities were
reflected at currently enacted income tax rates applicable to that period in
which the deferred tax assets and liabilities were expected to be realized or
settled.

  FINANCIAL INSTRUMENTS

     The Company has not acquired or issued any derivative financial
instruments.

     In the ordinary course of business the Company has entered into certain off
balance sheet financial instruments consisting of commitments to extend credit
and standby letters of credit. Such financial instruments are recorded in the
financial statements when they are funded or related fees are incurred or
received.

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used by the Company in
estimating fair values of financial instruments as disclosed herein:

  CASH AND SHORT TERM INSTRUMENTS

     The carrying amounts of cash and short term instruments approximate their
fair value.

  AVAILABLE FOR SALE AND HELD TO MATURITY SECURITIES

     Fair values for securities excluding restricted equity securities, are
based on quoted market prices. The carrying values of restricted equity
securities approximate fair values.

  LOANS

     For variable-rate loans that reprice frequently and have no significant
changes in credit risk, fair values are based on carrying values. Fair values
for certain mortgage loans (for example, one-to-four family residential) and
other consumer loans are based on quoted market prices of similar loans sold in
conjunction with securitization transactions, adjusted for differences in loan
characteristics. Fair values for commercial real estate and commercial loans are
estimated using discounted cash flow analyses, using interest rates

                                      F-10
<PAGE>
                TEXAS CENTRAL BANCSHARES, INC. AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

currently being offered for loans with similar terms to borrowers of similar
credit quality. Fair values for impaired loans are estimated using discounted
cash flow analyses or underlying collateral values, where applicable.

  DEPOSITS

     The fair values disclosed for demand deposits are, by definition, equal to
the amount payable on demand at the reporting date (that is, their carrying
amounts). The carrying amounts of variable-rate, fixed term money market
accounts and certificates of deposit (CD's) approximate their fair values at the
reporting date. Fair values for fixed-rate CD's are estimated using a discounted
cash flow calculation that applies interest rates currently being offered on
certificates to a schedule of aggregated expected monthly maturities on time
deposits.

  SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE

     The carrying amount of securities sold under agreements to repurchase
approximates their fair value.

  OTHER BORROWINGS

     The carrying amount of other borrowings approximates their fair value.

  ACCRUED INTEREST

     The carrying amounts of accrued interest approximate their fair values.

  OFF BALANCE SHEET INSTRUMENTS

     Fair values for off balance sheet lending commitments are based on fees
currently charged to enter into similar agreements taking into account the
remaining terms of the agreements and the counterparties' credit standings.

  RECLASSIFICATION

     Certain amounts previously reported have been reclassified to conform to
the current format.

2.  STATEMENT OF CASH FLOWS

     The Company reports on a net basis its cash receipts and cash payments for
time deposits accepted and repayments of those deposits, loans made to customers
and principal collections on those loans.

     The Company uses the indirect method to present cash flows from operating
activities. Other supplemental cash flow information for the years ended
December 31, 1998, 1997, and 1996 is presented as follows (in thousands):

     Interest expense for such interest bearing deposits was approximately
$548,000, $403,000, and $213,000 for the years ended December 31, 1998, 1997,
and 1996.

7.  INCOME TAXES

     The provision for income taxes for the years ended December 31, 1998, 1997,
and 1996, consisted of the following (in thousands):

<TABLE>

                                       =========  =========  =========
</TABLE>

     As discussed in Note 1, the Company changed its tax status from taxable to
nontaxable on January 1, 1998. Accordingly, the tax provision in 1998 for
financial reporting purposes differs from an amount determined by applying the
statutory tax rate to the pretax accounting income. The deferred expense for
1998 consists of the following (in thousands):

Deferred expense due to the
  elimination of the deferred tax
  assets at the date of election to S
  corporation........................  $      52
Deferred expense due to the recording
  of a deferred liability for the
  estimated corporate level tax on
  unrealized "net built-in
  gains"............................         74
                                       ---------
                                       $     126
                                       =========

     The 1997 and 1996 tax provision differs from the amount determined by
applying the statutory tax rate to pretax accounting income primarily because of
the effect of a leverage lease transaction.

     Deferred income taxes reflect the net tax effects of temporary differences
between the recorded amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities as of December 31, 1998, 1997,
and 1996 are as follows (in thousands):

     The net deferred tax liability for 1998 is included in other liabilities in
the accompanying consolidated financial statements. The net deferred tax asset
for 1997 and 1996 is included in other assets in the accompanying consolidated
financial statements.

     As of December 31, 1998, the Company has a net current income tax
receivable of approximately $40,000 included in other assets. As of December 31,
1997 and 1996, the Company had a current income tax payable of approximately
$135,000 and $150,000, respectively, included in other liabilities.

8.  BORROWED FUNDS

  ADVANCES FROM THE FHLB

     The Bank is a member of the Federal Home Loan Bank of Dallas (FHLB). During
1998, 1997, and 1996, the Bank had a FHLB Warehouse Line of Credit. At December
31, 1998, 1997, and 1996, the Bank had no outstanding advances from the FHLB.

     In addition, the Bank also has a long-term FHLB note in the original amount
of $350,000 which bears interest at 5.92%. Principal and interest are due
monthly, commencing February 1, 1994, through January 4, 2004. The outstanding
principal balance of the note was approximately $204,000, $237,000, and $268,000
at December 31, 1998, 1997, and 1996, respectively.

  SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE

     Also included in borrowed funds are borrowings incurred in connection with
securities sold under agreements to repurchase. These borrowings do not have a
set maturity, but the agreements may be canceled by either party upon written
notice. Additional information concerning such borrowings at December 31, 1998,
1997, and 1996, is summarized as follows (in thousands):

  LINE OF CREDIT

     The Bank has a $3,000,000 revolving line of credit with a third-party bank
for the periodic purchase of federal funds. The lending bank requires a security
interest in marketable securities. Advances under this credit facility bear
interest at the prevailing daily rate on the federal funds, which will be quoted
at the time of the requested advance. No principal advances related to the
agreement were outstanding at December 31, 1998, 1997 and 1996.

9.  COMMITMENTS AND CONTINGENCIES

     The Company is involved in legal actions arising from normal business
activities. Management believes that these actions are without merit or that the
ultimate liability, if any, resulting from them will not materially affect the
financial position or results of operations of the Company.

     The Company leases certain of its banking facilities under noncancellable
operating lease agreements. These agreements expire at various dates through
2006. Rent expense under the Company's operating lease agreements was
approximately $378,000, $264,000, and $176,000 for the years ended December 31,
1998, 1997, and 1996, respectively.

     Future minimum lease payments under noncancellable operating leases for
each of the next five years and thereafter are as follows (in thousands):

               YEAR ENDED
              DECEMBER 31,                 AMOUNT

                                           ======

     The Company does not anticipate any material losses as a result of
commitments and contingent liabilities.

     The Company has entered into a sublease with an affiliate of a director of
the Bank. The operating lease expires in July 1999 and provides annual rental
revenue of approximately $80,000. Rental payments received in regard to this
lease were approximately $48,000 during 1998.

10.  FINANCIAL INSTRUMENTS

     The Company is a party to financial instruments with off-balance sheet risk
in the normal course of business to meet the financing needs of its customers.
These financial instruments include commitments to extend credit and standby
letters of credit. Those instruments involve, to varying degrees, elements of
credit risk in excess of the amount recognized in the balance sheet.

     The Company's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for commitments to extend credit and
standby letters of credit is represented by the contractual amount of those
instruments. The Company uses the same credit policies in making commitments and
conditional obligations as it does for on balance sheet instruments. At December
31, 1998, 1997, and 1996, the approximate amounts of these financial instruments
were as follows (in thousands):

<TABLE>
<CAPTION>
                                            1998       1997       1996

Financial instruments whose contract
  amounts represent credit risk:
     Commitments to extend credit.......  $  17,585  $  10,638  $   8,760
     Standby letters of credit..........        631        310      1,119
                                          ---------  ---------  ---------
                                          $  18,216  $  10,948  $   9,879
                                          =========  =========  =========
</TABLE>

     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments may expire
without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. Management evaluates each customer's
credit-worthiness on a case-by-case basis. The amount of collateral obtained, if
deemed necessary by the Company upon extension of credit, is based on
management's credit evaluation of the counterparty.

     Standby letters of credit are conditional commitments issued by the Company
to guarantee the performance of a customer to a third party. Standby letters of
credit generally have fixed expiration dates or other termination clauses and
may require payment of a fee. The credit risk involved in issuing letters of
credit is essentially the same as that involved in extending loan facilities to
customers. The Company's policy for obtaining collateral and the nature of such
collateral is essentially the same as that involved in making commitments to
extend credit.

     Although the maximum exposure to loss is the amount of such commitments,
management currently anticipates no material losses from such activities.

</TABLE>

11.  SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK

     Most of the Company's business activity is with customers located within
Texas. Such customers are normally also depositors of the Company.

     The distribution of commitments to extend credit approximates the
distribution of loans outstanding. Standby letters of credit were granted
primarily to commercial borrowers.

     The contractual amounts of credit related financial instruments such as
commitments to extend credit and letters of credit represent the amounts of
potential accounting loss should the contract be fully drawn upon, the customer
default, and the value of any existing collateral become worthless.

     At December 31, 1998, 1997, and 1996, the Company had federal funds sold of
approximately $20,799,000, $17,040,000, and $14,945,000, respectively, to a
non-related financial institution.

12.  RELATED PARTY TRANSACTIONS

     In the ordinary course of business, the Company has and expects to continue
to have transactions, including borrowings, with its employees, officers,
directors and their affiliates. In the opinion of management, such transactions
are on the same terms, including interest rates and collateral requirements, as
those prevailing at the time for comparable transactions with unaffiliated
persons. At December 31, 1998, 1997, and 1996, the aggregate amounts of such
loans were approximately $2,039,000, $329,000, and $47,000, respectively. During
the year ended December 31, 1998, approximately $1,940,000 of new loans were
made and reductions totaled approximately $230,000. During the year ended
December 31, 1997, approximately $292,000 of new loans were made and reductions
totaled approximately $10,000.

13.  STOCKHOLDERS' EQUITY AND REGULATORY MATTERS

     The Bank is subject to certain restrictions on the amount of dividends that
it may declare without prior regulatory approval. At January 1, 1999,
approximately $1,974,000 of retained earnings were available for dividend
declaration without prior regulatory approval.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Bank is subject to various regulatory capital requirements administered
by federal banking agencies. Failure to meet minimum capital requirements can
initiate certain mandatory and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off balance sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.

     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to risk
weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1998, that the Bank
meets all capital adequacy requirements to which it is subject.

     As of December 31, 1998, 1997, and 1996, the Bank's capital ratios exceeded
those levels necessary to be categorized as "well capitalized" under the
regulatory framework for prompt corrective action. To be categorized as "well
capitalized" the Bank must maintain minimum total risk-based, Tier I risk-based
and Tier I leverage ratios as set forth in the table. There are no conditions or
events since December 31, 1998 that management believes have changed the Bank's
category.

     A comparison of the Bank's actual capital amounts and ratios to required
capital amounts and ratios is presented in the following table (amounts in
thousands):

14.  STOCK OPTION PLANS

     The Company has established stock option plans (Plans) applicable to 73,500
shares of the Company's common stock. Under the Plans, options can be granted to
full-time officers, key employees or directors of the Company. The Plans are
administered by the Board of Directors.

     Stock options under each Plan are granted at no less than the fair value of
such shares at the time of grant. The options can be exercised at varying times
within the option periods as specified in the plan agreements.

     The Company has elected to account for the Plan under Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, no compensation expense has been recognized for
the stock options.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Had compensation costs been determined on the basis of fair value pursuant
to FASB statement No. 123, "Accounting for Stock-Based Compensation,"
management has determined the effect on net earnings would have been
insignificant.

     In connection with the formation of TCBI during 1997, the options for
shares of the Bank's stock were converted to options for shares of TCBI stock.
Changes in options outstanding for 1998, 1997, and 1996 are as follows:

                     AGREEMENT AND PLAN OF REORGANIZATION

      This Agreement and Plan of Reorganization ("Agreement") dated as of March
23, 1999, is by and among Bank United Corp., a Delaware corporation ("BUC"), BUC
Acquisition Corporation II, a Texas corporation ("Acquisition Company"), and
Texas Central Bancshares, Inc., a Texas corporation ("Texas Central").

      WHEREAS, BUC and Texas Central believe that the acquisition of Texas
Central by BUC in the manner provided by, and subject to the terms and
conditions set forth in, this Agreement and all exhibits, schedules and
supplements hereto is desirable and in the best interests of their respective
institutions and shareholders.

      NOW, THEREFORE, in consideration of such premises and the mutual
representations, warranties, covenants and agreements contained herein, the
parties agree as set forth below:


                                 INTRODUCTION

      Texas Central is a bank holding company registered under the Bank Holding
Company Act of 1956, as amended ("BHC Act"), which owns 100% of the issued and
outstanding capital stock of Texas Central Bank, N.A., a national banking
association (the "Texas Central Bank"), indirectly through Texas Central
Bancshares of Delaware, Inc. ("Texas Central Delaware"). BUC is a savings and
loan holding company within the meaning of the Home Owners' Loan Act, as amended
(the "HOLA"), which owns 100% of the issued and outstanding capital stock of
Bank United, a federal savings bank ("Bank United"), indirectly through BNKU
Holdings, Inc. ("BU Holdings"). This Agreement provides for the acquisition of
all of the issued and outstanding common stock, $1.00 par value, of Texas
Central (the "Texas Central Stock") by BUC in connection with which Texas
Central will become a wholly-owned subsidiary of BUC and will continue its
existing operations as a Texas corporation. The acquisition of the Texas Central
Stock will be accomplished through the merger of Acquisition Company, a
to-be-formed Texas corporation and a wholly-owned subsidiary of BUC, with and
into Texas Central, with Texas Central surviving (the "Acquisition Merger"), all
pursuant to this Agreement and the Articles of Merger (including the related
Plan of Merger) by and between Texas Central, BUC and Acquisition Company, a
form of which is attached hereto as EXHIBIT A (the "Articles of Merger").

                                  ARTICLE I.

                            THE ACQUISITION MERGER

      Section 1.1 ACQUISITION MERGER. BUC Acquisition II shall merge with and
into Texas Central (the resulting company being referred to as the "Surviving
Company") as of the Effective Date, as defined in Section 6.2, under the charter
and Articles of Incorporation of Texas Central and each of the outstanding
shares of common stock of BUC Acquisition II shall and without any action on the
part of BUC be canceled and be converted into shares of common stock of the
Surviving Company. The shares of common stock of the Surviving Company into
which such BUC Acquisition II common stock is converted shall represent
ownership of 100% of the issued and outstanding capital stock of the Surviving
Company, all of which shall be owned by BUC.

      Section 1.2 ARTICLES OF INCORPORATION, BYLAWS AND FACILITIES OF SURVIVING
COMPANY. At the Effective Date and until thereafter amended, the Articles of
Incorporation of the Surviving Company shall be the Articles of Incorporation of
Texas Central as in effect at the Effective Date. Until altered, amended or
repealed as provided therein and in the Articles of Incorporation of the
Surviving Company, the Bylaws of the Surviving Company shall be the Bylaws of
Texas Central as in effect at the Effective Date. The main office of the
Surviving Company shall be the main office of Texas Central as of the Effective
Date, and all corporate acts, plans, policies, contracts, approvals and
authorizations of Texas Central and BUC Acquisition II and their respective
shareholders, boards of directors, committees elected or appointed thereby,
officers and agents, which were valid and effective immediately prior to the
Effective Date, shall be taken for all purposes as the acts, plans, policies,
contracts, approvals and authorization of the Surviving Company and shall be as
effective and binding thereon as the same were with respect to Texas Central and
BUC Acquisition II respectively, as of the Effective Date.

      Section 1.3 EFFECT OF ACQUISITION MERGER. At the Effective Date, the
corporate existence of Texas Central and BUC Acquisition II shall be merged into
and continued in the Surviving Company, and the Surviving Company shall be
deemed to be a continuation in entity and identity of Texas Central and BUC
Acquisition II. All rights, franchises and interests of Texas Central and BUC
Acquisition II, respectively, in and to any type of property and chooses in
action shall be transferred to and vested in the Surviving Company by virtue of
the Merger without any deed or other transfer. Surviving Company, without any
order or other action on the part of any court or otherwise, shall hold and
enjoy all rights of property, franchises and interest, including appointments,
designations and nominations, and all other rights and interests as trustee,
executor, administrator, transfer agent or registrar of stocks and bonds,
guardian of estates, assignee, receiver and committee of estates and lunatics,
and in every other fiduciary capacity, in the same manner and to the same extent
as such rights, franchises and interests were held or enjoyed by Texas Central
and BUC Acquisition II, respectively, as of the Effective Date.

                                    A-8
<PAGE>
      Section 1.4 LIABILITIES OF THE SURVIVING COMPANY. At the Effective Date,
the Surviving Company shall be liable for all liabilities of Texas Central and
BUC Acquisition II. All deposits, debts, liabilities and obligations of Texas
Central and of BUC Acquisition II, respectively, accrued, absolute, contingent
or otherwise, and whether or not reflected or reserved against on balance
sheets, books of account or records of Texas Central or BUC Acquisition II, as
the case may be, shall be those of the Surviving Company and shall not be
released or impaired by the Merger. All rights of creditors and other obligees
and all liens on property of either Texas Central or BUC Acquisition II shall be
preserved unimpaired.

      Section 1.5 ACQUISITION MERGER PRICE. At the Effective Date and upon and
by reason of the Acquisition Merger becoming effective, each share of Texas
Central Stock issued and outstanding immediately prior to the Effective Date,
excluding Dissenting Shares (as defined in Section 1.7 of this Agreement), and
any and all rights arising out of ownership of such Texas Central Stock shall,
without any action on the part of the holder thereof, be canceled and be
converted into the right to receive a number of shares of the Class A Common
Stock, $ 0.01par value, which is quoted under the symbol "BNKU" on The NASDAQ
Stock Market National Market (the "BUC Stock"), in a ratio to be determined in
accordance with Section 1.6 below. BUC shall not issue any certificates for
fractional shares of BUC Stock in connection with the Merger. In lieu of issuing
fractional shares, BUC shall pay cash for such fractional shares in an amount
determined by multiplying the Average Value Per Share, as hereinafter defined,
by the fractional share interest in BUC Stock to which the Texas Central
shareholder is entitled pursuant to the calculation in accordance with Section
1.6. The Average Value Per Share shall be the average of the daily reported
closing sales prices for a share of the BUC Stock in The NASDAQ Stock Market
National Market for the twenty successive trading days ending on the trading day
that is one trading day prior to closing.

      Section 1.6 CALCULATION OF BUC STOCK RATIO. The number of shares of BUC
Stock to be received for each share of Texas Central Stock will be the quotient
obtained by dividing (i) 710,000 by (ii) the total number of shares of Texas
Central Stock issued and outstanding on the Closing Date, which shall not exceed
350,340 shares (the "Merger Consideration"). In the event that the Average Value
Per Share, as calculated in accordance with Section 1.5, is less than $33.57, or
the closing sales price of the BUC Stock on the day immediately prior to the
proposed Effective Date is less than $32.00, the Board of Directors of Texas
Central may terminate this Agreement pursuant to Section 7.1(a)(iv) (B) or (C)
hereof.

      Section 1.7 DISSENTING SHARES. Each share of Texas Central Stock issued
and outstanding immediately prior to the Effective Date, the holder of which has
not voted in favor of the Merger and who has properly perfected his dissenter's
rights of appraisal by following the procedures set forth in Texas Business
Corporation Act (the "TBCA"), is referred to herein as a "Dissenting Share. "
Dissenting Shares owned by each holder thereof who has not exchanged his
certificates representing shares of Texas Central Stock for the corresponding
share of the Merger Consideration or otherwise has not effectively withdrawn or
lost his dissenter's rights, shall not be converted into or represent the right
to receive the corresponding share of the Merger Consideration pursuant to
Section 1.5 hereof and shall be entitled only to such rights as are available to
such holder pursuant to the

                                    A-9
<PAGE>
applicable provisions of the TBCA. Each holder of Dissenting Shares shall be
entitled to receive the value of such Dissenting Shares held by him in
accordance with the applicable provisions of the TBCA, provided such holder
complies with the procedures contemplated by and set forth in the applicable
provisions of the TBCA. If any holder of Dissenting Shares shall effectively
withdraw or lose his dissenter's rights under the applicable provisions of the
TBCA, such Dissenting Shares shall be converted into the right to receive the
corresponding share of the Merger Consideration in accordance with the
provisions of Section 1.5 hereof. The shares of Texas Central Stock (excluding
any Dissenting Shares) issued and outstanding immediately prior to Closing Date
are sometimes referred to herein as the "Exchange Shares."

      Section 1.8 EXCHANGE OF SHARES. (a) On or immediately prior to the
Effective Date, BUC shall deposit in trust with an exchange agent to be selected
by BUC (the "Exchange Agent"), for exchange in accordance with this Agreement,
certificates representing a number of shares of BUC Stock sufficient to pay the
Merger Consideration (excluding any Dissenting Shares), and the cash to be paid
in lieu of fractional shares of BUC Stock.

            (b) As soon as practicable after the Effective Date, the Exchange
Agent will mail to each holder of record of Exchange Shares a letter of
transmittal for use in exchanging such holder's certificates for the
corresponding share of the Merger Consideration. Each holder of Exchange Shares,
upon surrender of the certificates therefor to the Exchange Agent, accompanied
by a duly executed letter of transmittal, shall be entitled to receive (i) a
certificate representing that number of whole shares of BUC Stock to which such
holder of Exchange Shares shall have become entitled pursuant to the provisions
of this Article I, and (ii) a check representing the amount of cash in lieu of
fractional shares of BUC Stock, if any, which such holder has the right to
receive in respect of the certificate for the Exchange Shares surrendered
pursuant to the provisions of this Article I, and the certificate representing
the Exchange Shares so surrendered shall be canceled. Until so surrendered, each
stock certificate representing the Exchange Shares will be deemed for all
corporate purposes to represent and evidence solely the right to receive the
corresponding share of the Merger Consideration to be paid therefor pursuant to
this Agreement. Notwithstanding the foregoing, neither the Exchange Agent nor
any other party hereto shall be liable to any holder of certificates
representing Exchange Shares for any amount paid to a public official pursuant
to any applicable abandoned property, escheat or similar law. Except as required
by law, no interest shall be payable with respect to the cash payable for
fractional shares or the cash payable for Dissenting Shares and no dividends
shall be disbursed with respect to shares of BUC Stock until certificates
representing shares of Texas Central Stock are surrendered in exchange therefor.
If any shareholder of record of Texas Central is unable to locate any
certificate evidencing the Exchange Shares, the Exchange Agent shall deliver the
corresponding share of the Merger Consideration to the registered shareholder
upon receipt of a lost certificate affidavit and an indemnity agreement in a
form acceptable to BUC.

      Section 1.9 APPROVAL BY SHAREHOLDERS. This Agreement shall be submitted to
the shareholders of Texas Central for their approval in accordance with
applicable provisions of law and the respective Articles of Incorporation and
Bylaws of Texas Central. BUC and Texas Central shall proceed expeditiously and
cooperate fully in obtaining any other consents and approvals and the

                                    A-10
<PAGE>
taking of any other actions in satisfaction of all other requirements prescribed
by law or otherwise necessary for consummation of the Merger on the terms herein
provided, including, without limitation, the preparation and submission of all
necessary filings and certificates to the Office of Thrift Supervision (the
"OTS") and the Federal Deposit Insurance Corporation ("FDIC") and the Secretary
of State of Texas.

      Section 1.10 STOCK OPTION. The parties acknowledge that, contemporaneously
with the execution and delivery of this Agreement, Texas Central has granted to
BUC an option to purchase 60,334 shares of the Texas Central Stock, representing
19.9% of such shares on a fully-diluted basis, in the form attached hereto as
EXHIBIT B (the "Texas Central Stock Option").

of Section 4043 of ERISA for which the 30-day reporting requirement has not been
waived, has been required to be filed for any Compensation and Benefit Plan or

Plan.

            (d) All contributions or insurance premiums required to be made
under the terms of any Compensation and Benefit Plan or any employee benefit

accordance with the terms thereof" does not mean that the borrower has the
financial ability to pay a Loan or that any collateral is sufficient to result

amendments or additional agreements related to the Loans that are not reflected
in Texas Central Bank's records, and no claim of defense as to the enforcement
of any Loan has been asserted, and Texas Central Bank is not aware of any acts
or omissions that would give rise to any claim or right of rescission, set off,

Texas Central Bank has a rating of "satisfactory" as of its most recent CRA

Central Bank under the CRA.

be made or filed by BUC with any federal or state regulatory or supervisory
authority in connection with the matters contemplated by this Agreement and (ii)
any filings with the SEC, including the Registration Statement and the

represents and warrants that all information so furnished for inclusion in the
Registration Statement shall, to the best of its knowledge, be true and correct
in all material respects and will not omit any material fact necessary to make
the statements therein not misleading. Texas Central represents and warrants
that all information furnished for inclusion in the Prospectus and in any filing
with any federal or state regulatory or supervisory authority shall, to the best
of its knowledge, be true and correct in all material respects and will not omit
any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Texas Central will
indemnify and hold harmless BUC from and against any and all losses, claims,
damages, expenses or liabilities to which it may become subject under applicable
laws, rules and regulations and will reimburse BUC for any legal or other
expenses reasonably incurred by it in connection with investigating or defending
any actions whether or not resulting in liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
any such application or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary in order to make the state ments therein not misleading, but only
insofar as any such statement or omission was made in reliance upon and in
conformity with information furnished in writing by Texas Central expressly for
use therein. Texas Central agrees at any time, upon the request of BUC, to
furnish to BUC a

                                    A-31
<PAGE>
written letter or statement confirming to the best of its knowledge the accuracy
of the information with respect to Texas Central contained in any report or
other application or statement referred to in Sections 5.1 or 5.3 of this
Agreement, and confirming that the information with respect to Texas Central
contained in such document or draft was furnished expressly for use therein or,
if such is not the case, indicating the inaccuracies contained in such document
or indicating the information not furnished by Texas Central expressly for use
therein. The indemnity agreement contained in this Section 5.3 shall terminate
at Closing.

      Section 5.4 ACCESS TO PROPERTIES AND RECORDS. To the extent permitted by
law, Texas Central will afford the executive officers and authorized
representatives (including legal counsel, accountants and consultants) of BUC
full access to the properties, books and records of the Texas Central Companies
in order that BUC may have full opportunity to make such reasonable investiga
tion as it shall desire to make of the affairs of the Texas Central Companies,
provided, however, that such investigations shall be conducted in a manner so as
not to unreasonably interfere with the operations of the Texas Central
Companies, and the officers of Texas Central will furnish BUC with such
additional financial and operating data and other information as to the business
and properties of the Texas Central Companies as BUC shall, from time to time,
request. As soon as practicable after they become available, Texas Central will
deliver or make available to BUC all unaudited quarterly financial statements
prepared for the internal use of management of the Texas Central Companies and
all Call Reports filed by Texas Central Bank with the Department or the FDIC
after the date of this Agreement. All such financial statements shall be
prepared in accordance with generally accepted accounting principles applied on
a basis consistent with previous accounting periods. In the event of the
termination of this Agreement, BUC will return to Texas Central all documents
and other information obtained pursuant hereto and will keep confidential any
information obtained pursuant to this Agreement.

      Section 5.5 ACCOUNTING AND TAX TREATMENT. Texas Central agrees to use its
best efforts to cause the Acquisition Merger to qualify as a "pooling of
interests" for accounting purposes and as a "reorganization" within the meaning
of Section 368(a) of the Internal Revenue Code. Texas Central agrees not to take
any action that would cause the Acquisition Merger not to qualify as a "pooling
of interests" for accounting purposes or as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code.

      Section 5.6 STANDSTILL PROVISION. So long as this Agreement is in effect,
no Texas Central Company and none of their directors or officers shall
entertain, solicit or encourage any inquiries with respect to, or provide any
information to or negotiate with any other party with respect to any proposal
which could reasonably be expected to lead to the merger, consolidation,
acquisition, or sale of all or substantially all of the assets or any shares of
capital stock of any Texas Central Company. Texas Central agrees to notify BUC
immediately of any unsolicited acquisition proposals and provide reasonable
detail as to the identity of the proposed acquiror and the nature of the
proposed transaction.

      Section 5.7 PROXIES. Texas Central acknowledges that the persons listed in
SCHEDULE 5.7 have agreed to vote their shares of Texas Central Stock in favor of
this Agreement and the

                                    A-32

its designee an irrevocable proxy to vote such shares at the meeting of Texas
Central shareholders called to approve the Acquisition Merger pursuant to a
Voting Agreement and Irrevocable Proxy substantially in the form of EXHIBIT C to
this Agreement (each a "Voting Agreement"), which has been executed as of the
date of this Agreement.

      Section 5.8 DIVIDENDS. BUC and Texas Central agree that, between September
30, 1998 and the Effective Date, Texas Central may declare and pay cash
dividends in an amount equal to 39.6% of the taxable income of Texas Central as
estimated by Texas Central, and approved by BUC, in good faith, and no more.
Texas Central agrees to provide BUC written notice of any proposed cash dividend
at least 10 business days prior to the payment date of any proposed dividend.

      Section 5.9 ACCRUALS. Prior to the Effective Date and after consultation
with BUC, Texas Central shall, consistent with generally accepted accounting
principles, make such changes and modifications to its loan, accrual and reserve
policies and practices (including loan classification and allowance for credit
losses levels) and other accounting policies and practices to bring such
policies and practices into line with those presently followed by BUC, including
appropriate increases in its allowance for credit losses. Without limiting the
foregoing, the ratio of the reserve for loan losses to total loans outstanding
at Texas Central Bank will be maintained, between the date hereof and the
Effective Date, at a ratio not less than the ratio for such matters on November
30, 1998.

      Section 5.10 PRESS RELEASES. Texas Central agrees that it will not,
directly or indirectly, without the prior approval of BUC, issue any press
release or written statement for general circulation relating to the Agreement

regulation, and then only after making reasonable efforts to notify BUC in
advance.

      Section 5.11 NATURE OF DEPOSITS. The deposits of Texas Central Bank will
be on the Closing Date of substantially the same character, mix, type, and
makeup as such deposits are as of the date hereof. Such deposits shall include
no "brokered deposits", as such term is used in 12 U.S.C. 1831f, unless
otherwise agreed by BUC.

      Section 5.12 TERMINATION OF 401(K) PLAN. Texas Central shall terminate the
401(k) plan of the Texas Central Companies prior to the Effective Date in a
manner reasonably acceptable to Bank United.

      Section 5.13 INCENTIVE COMPENSATION OBLIGATIONS. Prior to the Effective

under any bonus, incentive compensation or similar plans of the Texas Central
Companies and receive a release of claims from all participants in such plans in
a form reasonably acceptable to Bank United.

      Section 5.14 VACATION PAYMENT OBLIGATIONS. Prior to the Effective Date,
Texas Central shall accrue any vacation obligations on the books of Texas
Central and discharge all such vacation obligations.

      Section 5.15 ENVIRONMENTAL REPORTS. Texas Central shall obtain, at its
sole expense, Phase I environmental assessments for each bank facility and each
non-residential OREO property. Oral reports of such environmental assessments
shall be delivered to BUC no later than four (4) weeks and written reports shall
be delivered to BUC no later than eight (8) weeks from the date of this
Agreement. Prior to the Effective Date, Texas Central shall obtain, at its sole
expense, Phase II environmental assessments for properties identified by BUC on
the basis of the results of such Phase I environmental assessments, which
reports shall be satisfactory to BUC. Texas Central shall obtain a survey and
assessment of all potential asbestos containing material in owned or leased
properties (other than OREO property) and a written report of the results shall
be delivered to BUC within four (4) weeks of execution of the definitive
agreement. Texas Central agrees to notify BUC a reasonable time in advance of
the examinations scheduled pursuant to this Section 5.15 and to permit BUC and
its contractors, consultants, agents and representatives to be present during
such examinations and to have such access to the properties and facilities of
Texas Central, and to conduct such consultations with the persons or firms
conducting such examinations, as BUC shall deem necessary.

      Section 5.16 STOCK OPTIONS. As soon as practicable after the date of this
Agreement, the Board of Directors of Texas Central (or, if appropriate, any
committee administering the Texas Central stock option plans) shall adopt such
resolutions or take such other actions as may be required to cause all options
to purchase shares of Texas Central Stock outstanding on the date hereof and
exercised or canceled prior to its Effective Date. Evidence satisfactory to BUC
of such cancellation or exercise shall be delivered to BUC prior to the
Effective Date.

      Section 5.17 AFFILIATE AGREEMENT. Within thirty (30) days after the date
of this Agreement, Texas Central shall enter into and cause each Texas Central
shareholder who is an "affiliate" (as defined in SEC Rule 405) of Texas Central
to enter into with BUC, an Affiliate Agreement in substantially the form of
EXHIBIT D attached hereto (each an "Affiliate Agreement").

      Section 5.18 DIRECTORS AND OFFICERS' LIABILITY INSURANCE AND
INDEMNIFICATION. (a) Following the Effective Date, BUC will provide the
directors and officers of Texas Central and its subsidiaries with the same
directors' and officers' liability insurance coverage that BUC provides to
directors and officers of its other banking subsidiaries generally, and, in
addition, for a period of three years will use its best efforts to continue
Texas Central's directors' and officers' liability insurance coverage with
respect to actions occurring prior to the Effective Date and to the extent that
such coverage is obtainable for an aggregate premium not in excess of the
aggregate premium paid by Texas Central for such insurance; provided, that BUC
may at its option elect to replace Texas Central's insurance coverage with
respect to actions occurring prior to the effective date with coverage provided
by other insurers having the same aggregate limits. If the aggregate premium for
such continued coverage would exceed the aggregate premium for such coverage
paid by Texas Central, BUC shall use its best efforts to procure such level of
insurance having the coverage described above as can be obtained for an
aggregate premium equal to the maximum amount paid by Texas Central.

            (b) For six years after the Effective Date, and subject to the
limitations contained in applicable OTS regulations, BUC shall cause the
Surviving Company to indemnify, defend and

                                    A-34
<PAGE>
hold harmless the present and former officers, directors, employees and agents
of Texas Central and its subsidiaries (each, an "Indemnified Party") against all
losses, expenses, claims, damages or liabilities arising out of actions or
omissions occurring on or prior to the Effective Date (including, without
limitation, the transactions contemplated by this Agreement) to the full extent
then permitted under the Texas Business Corporation Act and by Texas Central's
Articles of Incorporation as in effect on the date hereof, including provisions
relating to advances of expenses incurred in the defense of any action or suit.

      Section 5.19 SUPPLEMENTS TO DISCLOSURE SCHEDULES. From time to time prior
to the Effective Date, Texas Central shall promptly supplement or amend its
Disclosure Schedules to reflect any matter hereafter arising that would make any
representation or warranty set forth in Article II inaccurate. For purposes of
determining (i) the fulfillment of the condition set forth in Section 8.1 as of
the Closing Date and (ii) the accuracy of the representations and warranties
contained in Article II if the Acquisition Merger is not consummated, the
Disclosure Schedules shall be deemed to include only the information contained
therein on the date of this Agreement and shall be deemed to exclude any
information contained in any subsequent supplement or amendment thereto. If the
Acquisition Merger is not consummated, delivery of any supplemental disclosure
schedules will not affect the rights and remedies of the parties hereunder. For
purposes of determining the accuracy of the representations and warranties
contained in Article II or if the Acquisition Merger is consummated, the
Disclosure Schedules shall be deemed to include all information contained in any
supplement or amendment thereto made before the Closing Date. If any supplement
to any Disclosure Schedule shall be delivered within 10 days of the Closing
Date, at the option of BUC the Closing Date may be delayed to permit BUC to have
a period of at least 10 days to consider such supplement.

                                  ARTICLE VI.

                                    CLOSING

      Section 6.1 CLOSING. Subject to the other provisions of this Article VI,
at a mutually acceptable time, on a mutually acceptable date ("Closing Date") as
soon as practicable within a thirty-day period commencing with the latest of the
following dates:

            (i) the receipt of shareholder approval and the last approval from
      any requisite regulatory or supervisory authority and the expiration of
      any statutory or regulatory waiting period which is necessary to effect
      the Acquisition Merger, or

            (ii) if the matters contemplated by this Agreement are being
      contested in any legal proceeding and BUC or Texas Central, pursuant to
      Section 10.1 hereof, have elected to contest the same, then the date that
      such proceeding has been brought to a conclusion favorable, in the
      judgment of each of BUC and Texas Central, to the consummation of the
      Acquisition Merger, or such prior date as each of BUC and Texas Central
      shall elect whether or not such proceeding has been brought to a
      conclusion;

                                      A-35
<PAGE>
the closing of the Acquisition Merger ("Closing") will take place at which the
parties to this Agreement will exchange certificates, opinions, letters and
other documents provided for under this Agreement in order to effect the
Acquisition Merger and to determine whether any condition exists which would
permit the parties hereto to terminate this Agreement. If no such condition then
exists or if no party elects to exercise any right it may have to terminate this
Agreement, then and thereupon the appropriate parties shall execute such
documents and instruments as may be necessary or appropriate to effect the
Acquisition Merger contemplated by this Agreement.

      The Closing shall take place at the offices of Bank United in Houston,
Texas, or at such other place to which the parties hereto may mutually agree.

      Section 6.2 EFFECTIVE DATE. Subject to the terms and upon satisfaction of
all requirements of law and the conditions specified in this Agreement
including, among other conditions, the receipt of requisite approval of the
shareholders of Texas Central and the regulatory approvals (or waivers thereof)
of the OTS and the FRB and any other federal or state regulatory agency whose
approval must be received in order to consummate the Acquisition Merger, the
Acquisition Merger shall become effective, and the Effective Date of the
Acquisition Merger shall occur, at the date and time specified in the
certificate approving the Acquisition Merger to be issued by the Secretary of
State of Texas (the "Effective Date"). It is anticipated by BUC and Texas
Central that the Closing and the Effective Date will occur on the same day.


                                 ARTICLE VII.

                                  TERMINATION

      Section 7.1 TERMINATION. (a) This Agreement may be terminated by action of
the Board of Directors of BUC or the Board of Directors of Texas Central at any
time prior to the Effective Date if:

            (i) any court of competent jurisdiction in the United States or
      other United States (federal or state) governmental body shall have issued
      an order, decree or ruling or taken any other action restraining,
      enjoining, or otherwise prohibiting the Acquisition Merger and such order,
      decree, ruling or other action shall have been final and non-appealable;

            (ii) any of the transactions contemplated by this Agreement are
      disapproved by any regulatory authority or other person whose approval is
      required to consummate the Acquisition Merger; or

            (iii) the Effective Date shall not have occurred on or before
      September 17, 1999 or such later date as shall have been approved in
      writing by the Boards of Directors of BUC and Texas Central; provided,
      however, that the right to terminate under this Section 7.1(a)(3) shall
      not be available to any party whose failure to fulfill any obligation
      under this

                                    A-36
<PAGE>
      Agreement has been the cause of, or has resulted in, the failure of the
      Effective Date to occur on or before such date.

            (iv) This Agreement may be terminated at any time prior to the
      Effective Date by the Board of Directors of Texas Central if (A) BUC shall
      fail to comply in any material respect with any of its covenants or
      agreements contained in this Agreement, or if any of the representations
      or warranties of BUC contained herein shall be untrue in any material
      respect, (B) the Average Value Per Share as calculated in accordance with
      Section 1.6 is below $33.57, or (C) the closing price of the BUC Stock on
      the day immediately prior to the day fixed as the Closing Date shall be
      less than $32.00. In the event the Board of Directors of Texas Central
      desires to terminate this Agreement as provided in Section 7.1(a)(iv)(A)
      above, such Board of Directors must notify BUC in writing of its intent to
      terminate stating the reason therefor. BUC shall have fifteen days from
      the receipt of such notice to cure the alleged breach, inaccuracy or
      change, subject to the approval of Texas Central (which approval shall not
      be unreasonably delayed or withheld).

            (v) This Agreement may be terminated any time prior to the Effective
      Date by BUC if (A) Texas Central shall fail to comply in any material
      respect with any of its covenants or agreements contained in this
      Agreement, or if any of the representations or warranties of Texas Central
      contained herein shall be defective in any material respect, (B) there
      shall have been any change after December 31, 1998 in the assets,
      liabilities (including deposit liabilities) properties, business or
      financial condition of Texas Central, Texas Central Delaware or Texas
      Central Bank which individually or in the aggregate have materially and
      adversely affected the financial condition, results of operation or
      business of Texas Central, or (C) BUC concludes, in its reasonable
      discretion, that BUC will be unable to obtain any regulatory approval
      required in order to consummate the Acquisition Merger. In the event BUC
      desires to terminate this Agreement because of an alleged breach or change
      as provided in Section 7.1(a)(v)(A) or (B) above, BUC must notify Texas
      Central in writing of its intent to terminate stating the cause therefor.
      Texas Central shall have fifteen days from the receipt of such notice to
      cure the alleged breach, inaccuracy or change, subject to the approval of
      BUC (which approval shall not be unreasonably delayed or withheld).

            (vi) This Agreement may be terminated at any time prior to the
      Effective Date with the mutual written consent of BUC and Texas Central.

      Section 7.2 EFFECT OF TERMINATION. In the event of termination of this
Agreement and the abandonment of the Acquisition Merger without breach by any
party hereto, this Agreement shall become void and have no effect, without any
liability on the part of any party or the directors, officers or shareholders of
any corporate party. Nothing contained in this Section 7.2 shall relieve any
party hereto of any liability for a breach of this Agreement; PROVIDED, HOWEVER,
that BUC's remedy for a breach by Texas Central of the representation contained
in Section 2.15 shall be limited to termination of the Agreement and the receipt
of a cash payment from TCBI equal to the actual out of pocket expenses incurred
by BUC in connection with the transactions contemplated hereby, not to exceed
$250,000.

      The obligations of BUC under this Agreement are subject to the

may be waived by BUC in its sole discretion:

      Section 8.1 COMPLIANCE WITH REPRESENTATIONS. The representations and
warranties made by Texas Central in this Agreement must have been true when made
and shall be true in all material respects as of the Closing Date with the same
force and effect as if such representations and warranties were made at and as
of the Closing Date, and Texas Central shall have performed or complied with all
covenants and conditions required by this Agreement to be performed and complied
with by Texas Central prior to or at the Closing. BUC shall have been furnished
with a certificate, executed by an appropriate representative of Texas Central,

      Section 8.2 MATERIAL ADVERSE CHANGE. Prior to the Closing Date, there
shall not have occurred any material adverse change in the financial condition,

condition, results of operations, business or prospects of the Texas Central
Companies in the reasonable judgment of BUC. BUC shall have received a
certificate to the foregoing effect executed by an appropriate representative of
Texas Central and dated as of the Closing Date. Without limiting any other
circumstance which might constitute a material adverse change under this Section

adverse change: (i) a decrease in the aggregate amount of non-affiliate deposits
of Texas Central Bank to less than $86.4 million; or (ii) the ratio of
non-performing assets to gross loans shall exceed one and one-half (1 1/2)
percent.

      Section 8.3 LEGAL OPINION. BUC shall have received an opinion of counsel
to Texas Central, dated as of the Closing Date, substantially in the form
attached hereto as EXHIBIT E.

      Section 8.4 TAX OPINION. BUC shall have received an opinion from its

holders of Texas Central Stock upon receipt of BUC Stock, (iii) the aggregate
tax basis of BUC Stock received by a shareholder of Texas Central will be the
same as the aggregate basis of Texas Central Stock surrendered in exchange
therefor, and (iv) the holding period of BUC Stock to be received by each Texas

                                  ARTICLE XI.

                               EMPLOYEE MATTERS

      Section 11.1 OFFERS TO TEXAS CENTRAL EMPLOYEES. On or before 15 days prior
to Closing, BUC shall cause Bank United to offer employment, to become effective
as of the Effective Date, to the Employees of Texas Central or its subsidiaries
employed as of, or on, the Effective Date (the "Employees") whom Bank United
wishes to employ and give notice to Texas Central of the names of the Employees
whom BUC does not wish to employ. To the extent consistent with Bank United's
existing compensation structure for comparable positions and comparable officer
titles and its current policies regarding officer titles, all Employees offered
employment by Bank United shall be offered employment at base wages and salaries
no less favorable than the wages and salaries currently being received by such
Employees to such Employees and in positions with comparable responsibilities
and officer titles, and, unless agreed upon by such Employee before the
Effective Date, within a reasonable geographic proximity to such Employee's
current work location. BUC shall be responsible for advising Employees of the
details of any offers and terms of employment, and answering any questions
relating thereto, but Texas Central shall be allowed to review and promptly
approve any communication that refers to any of Texas Central's benefits or
policies prior to its distribution.

      Section 11.2 CREDIT FOR SERVICE WITH TEXAS CENTRAL. All Employees who are
offered and accept employment with BUC as of the Effective Date shall be
eligible to participate in the employee benefit plans and other fringe benefits
of BUC on the same basis as such plans and benefits are offered to employees of
BUC with comparable positions with BUC. To the extent possible under its
employee benefit plans, BUC shall credit such Employees for their length of
service with Texas Central for purposes of eligibility and vesting under each
employee benefit and fringe benefit plan to be provided by BUC to such
Employees, to the same extent such service was recognized under a similar plan
of Texas Central, based on information provided by Texas Central. For purposes
of this Section 11.2, "employee benefit plans and other fringe benefits"
includes, without limitation, health insurance benefits (medical and dental),
disability, life and accident insurance, sickness benefits, employee loans and
banking privileges, but does not include, if any, the incentive compensation,
pension, profit sharing, retirement and post retirement welfare benefits, and
vacation plans of Texas Central. If BUC offers a salary continuation or similar
program for employees unable to work for medical reasons, the Employees who are
offered and accept employment with BUC shall be credited under any program of
BUC with at least the number of sickness benefit days (up to a maximum of 22
calendar days) accrued under Texas Central's program at the Effective Date.

      Section 11.3 VACATION POLICY. Immediately prior to the Effective Date,
Texas Central shall pay all vacation accrued and not taken by Employees in
accordance with Section 5.14 and 12.2. In the calendar year in which the
Effective Date occurs, Employees who are offered and accept employment with BUC
shall be eligible to earn the annual vacation amount Employees would be eligible
to earn as employees of BUC or a BUC Subsidiary, without giving credit for the
Employees

                                    A-42
<PAGE>
length of service with Texas Central. In subsequent calendar years, Employees
will be eligible to earn vacation days according to the schedule specified in
BUC's vacation policy.

      Section 11.4 EMPLOYMENT AGREEMENTS. The parties acknowledge that, prior to
or contemporaneous with the execution and delivery of this Agreement, the
management personnel of the Texas Central Bank listed on SCHEDULE 11.4 each have
executed on the date hereof an Employment Agreement and Agreement Not to Compete
in the form attached hereto as EXHIBIT J (each, an "Employment Agreement"), with
BUC or one of the BUC Subsidiaries, which shall become effective on the Closing
Date.

                                 ARTICLE XII.

                                 MISCELLANEOUS

      Section 12.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Notwithstanding
the indemnities set forth in Sections 4.2 and 5.3 of this Agreement, the
representations, warranties, covenants and indemnities of BUC and Texas Central
contained in this Agreement shall not survive the Effective Date.

      Section 12.2 EXPENSES. Whether or not the transactions provided for herein
are consummated, each party to this Agreement will pay its respective expenses
incurred in connection with the preparation and performance of its obligations
under this Agreement. Except as to a fee to be paid by Texas Central and
expensed and fully accrued on its books prior to the Effective Date to SAMCO,
not to exceed $500,000 which will be paid by Texas Central but will not be
deducted from the Merger Consideration referenced Section 1.6, each party agrees
to indemnify the other parties against any cost, expense or liability (including
reasonable attorney's fees) in respect of any claim made by any party for a
broker's or finder's fee in connection with this transaction other than one
based on communications between the party and the claimant seeking
indemnification. BUC and Texas Central further agree that, except for the fee to
be paid by Texas Central to SAMCO, all legal, accounting and other fees and
expenses incurred by Texas Central in connection with this Agreement in excess
of $100,000 will be deducted from the total Merger Consideration to be paid by
BUC under Section 1.6, above. All such legal, accounting or other fees and
expenses will be expensed and fully accrued on the books of Texas Central prior
to the Effective Date. BUC and Texas Central also agree that any fees, expenses
and payments associated with the funding or payment of the bonuses, incentive
compensation plans and vacation pay required by Sections 5.13 and 5.14 will be
the responsibility of Texas Central, will not be deducted from the Merger
Consideration, will not be included in the calculation of fees and expenses in
the previous sentence and will be expensed and fully accrued on the books of
Texas Central and discharged prior to the Effective Date.

June 15, 1999

The Board of Directors
Texas Central Bancshares, Inc.
401 West Texas, Suite 100
Texas Central, Texas  79701-4414
Attention:  Michael Ruff

Members of the Board:

      We understand that Texas Central Bancshares, Inc. ("TCBI"), Bank United
Corp., a Delaware corporation ("BUC"), and BUC Acquisition Corporation II, a
Texas corporation ("Acquisition Company") have entered into an Agreement and
Plan of Reorganization (the "Merger Agreement") dated March 23, 1999, which
provides for the merger (the "Merger") of TCBI and its subsidiary, Texas Central
Bank National Association ("Texas Central" or the "Bank"), with and into a new
wholly owned Texas subsidiary corporation of BUC (the Acquisition Company).
Pursuant to the terms of the Merger Agreement, each issued and outstanding share
of common stock, par value $1.00, of TCBI, as of the date the Merger becomes
effective, will be converted into the right to receive 2.02797 (the "Exchange
Ratio") shares of Bank United Corp. Class A Common Stock, par value $0.01, not
to exceed in the aggregate 710,000 shares, as described in the Merger Agreement,
with certain provisions for fractional shares. The terms and conditions of the
Merger are more fully set forth in the Merger Agreement. We understand that as a
result of the Merger, (i) TCBI and the Acquisition Company shall each be merged
with and into BUC and each will cease to exist and that (ii) Texas Central will
be merged with and into Bank United Corp. and will cease its separate existence.

      You have asked for our opinion as to whether the Exchange Ratio pursuant
to the Merger Agreement is fair, from a financial point of view, to holders of
the TCBI common stock.

      Our opinion is based on information furnished to us by TCBI and BUC, their
attorneys, accountants, or obtained by us from published and verbal sources we
consider relevant. We have relied upon and assumed the accuracy and completeness
of all information submitted to us or that was publicly available and have made
no independent verification of this information. We have not conducted any
valuation or appraisal of any assets or liabilities, nor have any such
valuations or appraisals been provided to us. In relying upon financial analyses
and forecasts provided to us, we have assumed that they have been reasonably
prepared based on assumptions reflecting the best currently available estimates
and judgments by management of TCBI and BUC as to the expected future results of
operations and financial condition of TCBI and BUC to which such analyses or
forecasts relate. We have relied as to all legal matters relevant to rendering
our opinion upon the

                                      B-1
<PAGE>
advice of counsel. TCBI and BUC's management have informed us that they know of
no additional information which would have a material effect upon our valuation.

      In arriving at our opinion, we have followed generally accepted industry
practices for the valuation of commercial banks and have used such valuation
methodologies as we have deemed necessary or appropriate for the purposes of
this opinion. In giving our opinion, we have given consideration to all
available financial data and other relevant factors effecting fair market value
including, but not limited to the following, (i) reviewed certain publicly
available financial statements and other information of TCBI and BUC, (ii)
reviewed certain internal financial statements and other financial and operating
data concerning TCBI and BUC prepared by the management of TCBI and BUC, (iii)
analyzed certain summary financial projections concerning TCBI and BUC prepared
by the management of TCBI and BUC, respectively; (iv) reviewed and discussed
with senior executives of TCBI the past and current operations and prospects of
TCBI, (v) reviewed and discussed with senior executives of BUC the past and
current operations and financial condition and the prospects of BUC and analyzed
the estimated pro forma impact of the Merger, including on the combined
company's earnings per share, consolidated capitalization and financial ratios,
(vi) reviewed and discussed with senior executives of TCBI and BUC the strategic
objectives of the Merger and the long term benefits expected to result from the
Merger, including without limitation, certain estimates and timing of synergies
and other cost savings for the continued company, (vii) reviewed reported prices
and trading activity for transactions in TCBI stock and BUC stock, (viii)
compared the financial performance of TCBI and BUC and the prices and trading
activity of TCBI and BUC with that of certain other comparable publicly traded
companies and their securities, (ix) reviewed the financial terms, to the extent
publicly available, of certain comparable transactions, (x) reviewed the Merger
Agreement and certain related documents, and (xi) considered other such factors
as we have deemed appropriate.

      Neither SAMCO Capital Markets ("SAMCO") nor the individuals involved in
this valuation have any present or contemplated future financial interest in
TCBI or BUC which might prevent them from rendering a fair and unbiased opinion.
Our opinion is necessarily based upon the business, market, economic and other
conditions as they exist on, and can be evaluated as of, the date of this
letter, and does not address TCBI's underlying business decision to enter into
the Merger Agreement or constitute any recommendations to any holder of common
stock of TCBI as to how such holder should vote with respect to the Merger
Agreement. We were requested to, and did, solicit third party offers to acquire
all or any part of TCBI. In addition, we understand that the Merger may render
in effect a taxable transaction and our opinion may be used for purposes of the
shareholders in determining the tax liability they may have upon conversion.

      In reaching our opinion, we have assumed that the Merger will be
consummated in accordance with the terms described in the Merger Agreement. We
consent to the reference to our firm and the inclusion of our opinion in its
entirety in any filing with the Securities and Exchange Commission related to
the Merger. Based on the foregoing and in consideration of all relevant factors,
it is our opinion, as of the date of this letter, that the Exchange Ratio is
fair and equitable to all holders of Texas Central Bancshares, Inc. common
stock, from a financial point of view.

ARTICLE 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 market 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

                                    C-2
<PAGE>
         to discharge the shareholder's right of dissent, in the case of a
         merger, shall, within ten (10) days after the date the action is
         effected, mail to each shareholder of record as of the effective date
         of the action notice of the fact and date of the action and that the
         shareholder may exercise the shareholder's right to dissent from the
         action. The notice shall be accompanied by a copy of this Article and
         any articles or documents filed by the corporation with the Secretary
         of State to effect the action. If the shareholder shall not have
         consented to the taking of the action, the shareholder may, within
         twenty (20) days after the mailing of the notice, make written demand
         on the existing, surviving, or new corporation (foreign or domestic) or
         other entity, as the case may be, for payment of the fair value of the
         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 may be, do not so agree,
then the shareholder or the corporation (foreign or domestic) or other entity
may, within sixty (60) days after the expiration of the sixty (60) day period,
file a

                                    C-3
<PAGE>
petition in any court of competent jurisdiction in the county in which the
principal office of the domestic corporation is located, asking for a finding
and determination of the fair 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 he 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 of 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 valuating, and they shall make
a determination of the fair value of the shares upon such investigation as to
them may seem proper. The appraisers shall also afford a reasonable opportunity
to the parties interested to submit to them pertinent evidence as to the value
of the shares. The appraisers shall also have such power and authority as may be
conferred on Masters in Chancery by the Rules of Civil Procedure or by the order
of their appointment.

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

                                    C-4
<PAGE>
     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 the filing of the articles of merger, the surviving corporation is the
owner of all the outstanding shares of the other corporations, domestic or
foreign, that are parties to the merger.

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

ARTICLE 5.13.PROVISIONS AFFECTING REMEDIES OF DISSENTING SHAREHOLDERS

     A. Any shareholder who has demanded payment for his shares in accordance
with 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 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 right under Article 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 Article 5.12 or 5.16 of this Act may withdraw such demand at any time
before payment for his shares or

                                    C-5
<PAGE>
before any petition has been filed pursuant to Article 5.12 or 5.16 of this Act
asking for a finding and determination of the fair value of such shares, but no
such demand may be withdrawn after such payment has been made or, unless the
corporation shall consent thereto, after any such petition has been filed. If,
however, such demand shall be withdrawn as hereinbefore provided, or if pursuant
to Section B of this Article the corporation shall terminate the shareholder's
rights under Article 5.12 or 5.16 of this Act, as the case may be, or if no
petition asking for a finding and determination of fair value of such shares by
a court shall have been filed within the time provided in Article 5.12 or 5.16
of this Act, as the case may be, or if after the hearing of a petition filed
pursuant to Article 5.12 or 5.16, the court shall determine that such
shareholder is not entitled to the relief provided by 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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Bank United Corp. is a Delaware corporation. Section 145 of the General
Corporation Law of the State of Delaware (the "DGCL") contains detailed
provisions on indemnification of directors and officers of a Delaware
corporation against expenses, judgments, fines and amounts paid in settlement
actually and reasonably incurred in connection with certain litigation.

      Bank United Corp.'s Restated Certificate of Incorporation (the
"Certificate of Incorporation") provides that a director of Bank United Corp.
will not be personally liable to Bank United Corp. or its stockholders for
monetary damages for breach of fiduciary duty as a director, except, if required
by the DGCL as amended from time to time, for liability (i) for any breach of
the director's duty of loyalty to Bank United Corp. or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) under Section 174 of the DGCL, which
concerns unlawful payments of dividends, stock purchases or redemptions, or (iv)
for any transaction from which the director derived an improper personal
benefit. Neither the amendment nor repeal of such provision will eliminate or
reduce the effect of such provision in respect of any matter occurring, or any
cause of action, suit or claim that, but for such provision, would accrue or
arise prior to such amendment or repeal.

      While the Certificate of Incorporation provides directors with protection
from awards for monetary damages for breaches of their duty of care, it does not
eliminate such duty. Accordingly, the Certificate of Incorporation will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of his or her duty of care.

      The Certificate of Incorporation provides that each person who was or is
made a party or is threatened to be made a party to or is involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person, or a person of whom such
person is the legal representative, is or was a director or officer of Bank
United Corp. or is or was serving at the request of Bank United Corp. as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee or agent or in any
other capacity while serving as a director, officer, employee or agent, will be
indemnified and held harmless by Bank United Corp. to the fullest extent
authorized by the DGCL, as the same exists or may hereafter be amended (but, in
the case of any such amendment, only to the extent that such amendment permits
Bank United Corp. to provide broader indemnification rights than said law
permitted Bank United Corp. to provide prior to such amendment), against all
expense, liability and loss reasonably incurred or suffered by such person in
connection therewith. Such right to indemnification includes the right to have
Bank United Corp. pay the expenses incurred in defending any such proceeding in
advance of its final disposition, subject to the provisions of the DGCL. Such
rights are not exclusive of any other right which any person may have or
thereafter acquire under any statute, provision of the Certificate of
Incorporation, By-Laws, agreement, vote of stockholders or disinterested
directors or otherwise. No repeal or modification of such provision will in any
way diminish or adversely affect the rights of any director, officer, employee
or agent of Bank United Corp. thereunder in respect of any occurrence or matter
arising prior to any such repeal or modification. The Certificate of
Incorporation also specifically authorizes the Registrant to maintain insurance
and to grant similar indemnification rights to employees or agents of the
Registrant.

requirements of section 10(a)(3) of the Securities Act of 1933 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

      WHEREAS, BUC and Texas Central believe that the acquisition of Texas
Central by BUC in the manner provided by, and subject to the terms and
conditions set forth in, this Agreement and all exhibits, schedules and

                                 INTRODUCTION

      Texas Central is a bank holding company registered under the Bank Holding
Company Act of 1956, as amended ("BHC Act"), which owns 100% of the issued and
outstanding capital stock of Texas Central Bank, N.A., a national banking
association (the "Texas Central Bank"), indirectly through Texas Central
Bancshares of Delaware, Inc. ("Texas Central Delaware"). BUC is a savings and
loan holding company within the meaning of the Home Owners' Loan Act, as amended
(the "HOLA"), which owns 100% of the issued and outstanding capital stock of
Bank United, a federal savings bank ("Bank United"), indirectly through BNKU
Holdings, Inc. ("BU Holdings"). This Agreement provides for the acquisition of
all of the issued and outstanding common stock, $1.00 par value, of Texas
Central (the "Texas Central Stock") by BUC in connection with which Texas
Central will become a wholly-owned subsidiary of BUC and will continue its
existing operations as a Texas corporation. The acquisition of the Texas Central
Stock will be accomplished through the merger of Acquisition Company, a
to-be-formed Texas corporation and a wholly-owned subsidiary of BUC, with and
into Texas Central, with Texas Central surviving (the "Acquisition Merger"), all
pursuant to this Agreement and the Articles of Merger (including the related
Plan of Merger) by and between Texas Central, BUC and Acquisition Company, a

part of BUC be canceled and be converted into shares of common stock of the
Surviving

                                    -1-
<PAGE>
Company. The shares of common stock of the Surviving Company into which such BUC
Acquisition II common stock is converted shall represent ownership of 100% of
the issued and outstanding capital stock of the Surviving Company, all of which
shall be owned by BUC.

      Section 1.2 ARTICLES OF INCORPORATION, BYLAWS AND FACILITIES OF SURVIVING
COMPANY. At the Effective Date and until thereafter amended, the Articles of
Incorporation of the Surviving Company shall be the Articles of Incorporation of
Texas Central as in effect at the Effective Date. Until altered, amended or
repealed as provided therein and in the Articles of Incorporation of the
Surviving Company, the Bylaws of the Surviving Company shall be the Bylaws of
Texas Central as in effect at the Effective Date. The main office of the
Surviving Company shall be the main office of Texas Central as of the Effective
Date, and all corporate acts, plans, policies, contracts, approvals and
authorizations of Texas Central and BUC Acquisition II and their respective
shareholders, boards of directors, committees elected or appointed thereby,
officers and agents, which were valid and effective immediately prior to the
Effective Date, shall be taken for all purposes as the acts, plans, policies,
contracts, approvals and authorization of the Surviving Company and shall be as
effective and binding thereon as the same were with respect to Texas Central and
BUC Acquisition II respectively, as of the Effective Date.

      Section 1.3 EFFECT OF ACQUISITION MERGER. At the Effective Date, the
corporate existence of Texas Central and BUC Acquisition II shall be merged into
and continued in the Surviving Company, and the Surviving Company shall be
deemed to be a continuation in entity and identity of Texas Central and BUC
Acquisition II. All rights, franchises and interests of Texas Central and BUC
Acquisition II, respectively, in and to any type of property and chooses in
action shall be transferred to and vested in the Surviving Company by virtue of
the Merger without any deed or other transfer. Surviving Company, without any

designations and nominations, and all other rights and interests as trustee,
executor, administrator, transfer agent or registrar of stocks and bonds,

and in every other fiduciary capacity, in the same manner and to the same extent
as such rights, franchises and interests were held or enjoyed by Texas Central
and BUC Acquisition II, respectively, as of the Effective Date.

      Section 1.4 LIABILITIES OF THE SURVIVING COMPANY. At the Effective Date,
the Surviving Company shall be liable for all liabilities of Texas Central and

Central and of BUC Acquisition II, respectively, accrued, absolute, contingent
or otherwise, and whether or not reflected or reserved against on balance

      Section 1.5 ACQUISITION MERGER PRICE. At the Effective Date and upon and
by reason of the Acquisition Merger becoming effective, each share of Texas
Central Stock issued and outstanding immediately prior to the Effective Date,
excluding Dissenting Shares (as defined in Section 1.7 of this Agreement), and
any and all rights arising out of ownership of such Texas Central Stock shall,
without any action on the part of the holder thereof, be canceled and be
converted into the right to receive a number of shares of the Class A Common
Stock, $ 0.01par value, which is quoted under the symbol "BNKU" on The NASDAQ
Stock Market National Market (the "BUC Stock"), in a ratio to be determined in
accordance with Section 1.6 below. BUC shall not issue any certificates for
fractional shares of BUC Stock in connection with the Merger. In lieu of issuing
fractional shares, BUC shall pay cash for such fractional shares in an amount
determined by multiplying the Average Value Per Share, as hereinafter defined,
by the fractional share interest in BUC Stock to which the Texas Central
shareholder is entitled pursuant to the calculation in accordance with Section
1.6. The Average Value Per Share shall be the average of the daily reported
closing sales prices for a share of the BUC Stock in The NASDAQ Stock Market
National Market for the twenty successive trading days ending on the trading day
that is one trading day prior to closing.

      Section 1.6 CALCULATION OF BUC STOCK RATIO. The number of shares of BUC
Stock to be received for each share of Texas Central Stock will be the quotient
obtained by dividing (i) 710,000 by (ii) the total number of shares of Texas
Central Stock issued and outstanding on the Closing Date, which shall not exceed
350,340 shares (the "Merger Consideration"). In the event that the Average Value
Per Share, as calculated in accordance with Section 1.5, is less than $33.57, or
the closing sales price of the BUC Stock on the day immediately prior to the
proposed Effective Date is less than $32.00, the Board of Directors of Texas
Central may terminate this Agreement pursuant to Section 7.1(a)(iv) (B) or (C)
hereof.

      Section 1.7 DISSENTING SHARES. Each share of Texas Central Stock issued
and outstanding immediately prior to the Effective Date, the holder of which has
not voted in favor of the Merger and who has properly perfected his dissenter's
rights of appraisal by following the procedures set forth in Texas Business
Corporation Act (the "TBCA"), is referred to herein as a "Dissenting Share. "
Dissenting Shares owned by each holder thereof who has not exchanged his
certificates representing shares of Texas Central Stock for the corresponding
share of the Merger Consideration or otherwise has not effectively withdrawn or
lost his dissenter's rights, shall not be converted into or represent the right
to receive the corresponding share of the Merger Consideration pursuant to
Section 1.5 hereof and shall be entitled only to such rights as are available to
such holder pursuant to the applicable provisions of the TBCA. Each holder of
Dissenting Shares shall be entitled to receive the value of such Dissenting
Shares held by him in accordance with the applicable provisions of the TBCA,
provided such holder complies with the procedures contemplated by and set forth
in the applicable provisions of the TBCA. If any holder of Dissenting Shares
shall effectively withdraw or lose his dissenter's rights under the applicable
provisions of the TBCA, such Dissenting Shares shall be converted into the right
to receive the corresponding share of the Merger Consideration in accordance
with the provisions of Section 1.5 hereof. The shares of Texas Central Stock
(excluding any Dissenting Shares) issued and outstanding immediately prior to
Closing Date are sometimes referred to herein as the "Exchange Shares."

                                    -3-
<PAGE>
      Section 1.8 EXCHANGE OF SHARES. (a) On or immediately prior to the
Effective Date, BUC shall deposit in trust with an exchange agent to be selected
by BUC (the "Exchange Agent"), for exchange in accordance with this Agreement,
certificates representing a number of shares of BUC Stock sufficient to pay the
Merger Consideration (excluding any Dissenting Shares), and the cash to be paid
in lieu of fractional shares of BUC Stock.

            (b) As soon as practicable after the Effective Date, the Exchange
Agent will mail to each holder of record of Exchange Shares a letter of
transmittal for use in exchanging such holder's certificates for the
corresponding share of the Merger Consideration. Each holder of Exchange Shares,
upon surrender of the certificates therefor to the Exchange Agent, accompanied
by a duly executed letter of transmittal, shall be entitled to receive (i) a
certificate representing that number of whole shares of BUC Stock to which such
holder of Exchange Shares shall have become entitled pursuant to the provisions
of this Article I, and (ii) a check representing the amount of cash in lieu of
fractional shares of BUC Stock, if any, which such holder has the right to
receive in respect of the certificate for the Exchange Shares surrendered
pursuant to the provisions of this Article I, and the certificate representing
the Exchange Shares so surrendered shall be canceled. Until so surrendered, each
stock certificate representing the Exchange Shares will be deemed for all
corporate purposes to represent and evidence solely the right to receive the
corresponding share of the Merger Consideration to be paid therefor pursuant to
this Agreement. Notwithstanding the foregoing, neither the Exchange Agent nor
any other party hereto shall be liable to any holder of certificates
representing Exchange Shares for any amount paid to a public official pursuant
to any applicable abandoned property, escheat or similar law. Except as required
by law, no interest shall be payable with respect to the cash payable for
fractional shares or the cash payable for Dissenting Shares and no dividends
shall be disbursed with respect to shares of BUC Stock until certificates
representing shares of Texas Central Stock are surrendered in exchange therefor.
If any shareholder of record of Texas Central is unable to locate any
certificate evidencing the Exchange Shares, the Exchange Agent shall deliver the
corresponding share of the Merger Consideration to the registered shareholder
upon receipt of a lost certificate affidavit and an indemnity agreement in a
form acceptable to BUC.

      Section 1.9 APPROVAL BY SHAREHOLDERS. This Agreement shall be submitted to
the shareholders of Texas Central for their approval in accordance with
applicable provisions of law and the respective Articles of Incorporation and
Bylaws of Texas Central. BUC and Texas Central shall proceed expeditiously and
cooperate fully in obtaining any other consents and approvals and the taking of
any other actions in satisfaction of all other requirements prescribed by law or
otherwise necessary for consummation of the Merger on the terms herein provided,
including, without limitation, the preparation and submission of all necessary
filings and certificates to the Office of Thrift Supervision (the "OTS") and the
Federal Deposit Insurance Corporation ("FDIC") and the Secretary of State of
Texas.

      Section 1.10 STOCK OPTION. The parties acknowledge that, contemporaneously
with the execution and delivery of this Agreement, Texas Central has granted to
BUC an option to purchase 60,334 shares of the Texas Central Stock, representing
19.9% of such shares on a fully-diluted basis, in the form attached hereto as

loan losses of Texas Central Bank has been calculated in accordance with
generally accepted accounting principles as applied to banking institutions and
in accordance with all applicable rules and regulations. Such reserve shown on
Texas Central Bank's Call Report of December 31, 1998, is adequate in all
respects to provide for all losses, net of recoveries relating to loans
previously charged off, on loans outstanding as of December 31, 1998. On the

as "Other Assets Especially Mentioned," "Substandard," "Doubtful" or "Loss."

      Section 2.16 EMPLOYMENT RELATIONS. The relations of each Texas Central
Company with its employees are satisfactory, and they have not received any
notice of any controversies with, or organizational efforts or other pending
actions by, representatives of their employees. The Texas Central Companies have

labor with respect to their employees, including any provisions thereof relating

      Section 2.17 EMPLOYEE BENEFIT PLANS. (a) SCHEDULE 2.17(A) contains a
complete and accurate list of all employee benefit plans and programs, and
bonus, incentive, deferred compensation, pension, retirement, profit-sharing,
thrift, savings, employee stock ownership, stock bonus, stock purchase,
restricted stock, stock option, stock appreciation, phantom stock, severance,
welfare and fringe benefit plans, contracts, employment, collective bargaining,
or severance agreements written and unwritten and all similar practices,
policies and arrangements in which any Texas Central Company has any liability,
obligation to, or which is maintained or contributed to by either of them or
which covers any employees, or former employees, consultants or former
consultants, officers or former officers, directors or former directors of them,
which are now in force or which have been in force during the last three years
(the "COMPENSATION AND BENEFIT PLANS"). There is no commitment to create any
additional Compensation and Benefit Plan or to modify or change any existing
Compensation and Benefit Plan.

            (b) Each Compensation and Benefit Plan is in compliance in all
material respects, in form and in administration, with the plan documents and
all applicable laws, including, the extent applicable, ERISA, the Internal
Revenue Code, federal securities laws, the Age Discrimination in Employment Act,
or any regulations or rules promulgated thereunder, and all material filings,
disclosures and notices required by ERISA, the Internal Revenue Code, federal
securities laws, the Age Discrimination in Employment Act and any other
applicable law have been timely made. No Compensation and Benefit Plan is an
"employee pension benefit plan" within the meaning of Section 3(2) of ERISA (a
"PENSION PLAN") which is required to be qualified under Section 401(a) of the
Internal Revenue Code. There is no pending or, to the knowledge of Texas
Central, threatened legal action, suit or claim relating to the Compensation and
Benefit Plans. No transaction or omission with respect to any Compensation and
Benefit Plan exists that would be a violation of Section 4975 of the Code or
Section 502 of ERISA that is not exempt under Code Section 4975 or ERISA Section
502.

            (c) Neither Texas Central nor any entity which is a member of a
controlled group or affiliated service group with Texas Central under ERISA
Section 4001 or Section 414 of the Code ("ERISA AFFILIATE") maintains or has
ever maintained or contributed to a Pension Plan subject to title IV of ERISA or
Section 412 of the Code. No notice of a "reportable event", within the meaning
of Section 4043 of ERISA for which the 30-day reporting requirement has not been
waived, has been required to be filed for any Compensation and Benefit Plan or
any plan of an ERISA Affiliate within the 12-month period ending on the date
hereof, and no such notice will be required to be filed as a result of the
transactions contemplated by this Agreement. There is no pending investigation
or enforcement action by the Department Of Labor or Internal Revenue Service or
any other Governmental Authority with respect to any Compensation and Benefit
Plan.

            (d) All contributions or insurance premiums required to be made
under the terms of any Compensation and Benefit Plan or any employee benefit
arrangements under any collective

                                    -13-
<PAGE>
bargaining agreement to which Texas Central or an ERISA Affiliate is a party
have been timely made or will be timely made prior to the Effective Time.

            (e) No Texas Central Company has any obligation to provide retiree
health and life insurance or other retiree death benefits under any Compensation
and Benefit Plan, other than benefits mandated by Section 4980B of the Internal
Revenue Code and Sections 601-609 of ERISA. There has been no written or oral
communication to employees that promises or guarantees such employees retiree
health or life insurance or other retiree death benefits on a permanent basis.
Except as disclosed in SCHEDULE 2.17(E), Texas Central Bank may terminate or
amend any Compensation and Benefit Plan in which Texas Central Bank's or its
affiliates employees or former employees participate at any time without
incurring any liability thereunder. Except as disclosed in SCHEDULE 2.17(E), the
plan administrator of each Compensation and Benefit Plan in which such employees
or former employees participate has the sole discretion to construe and
interpret the terms of the plan.

            (f) No Texas Central Company maintains any Compensation and Benefit
Plans covering foreign employees.

            (g) With respect to each Compensation and Benefit Plan, if
applicable, Texas Central has furnished to BUC, true and complete copies of: (i)
Compensation and Benefit Plan documents and all amendments thereto; (ii) trust
instruments and insurance contracts; (iii) Forms 5500 filed with the IRS for the
last 3 plan years; (iv) most recent financial statement; (v) the most recent
summary plan description and any other communication to employees regarding such
benefits including employee booklets; and (f) most recent determination letter
issued by the IRS.

            (h) Except as disclosed in SCHEDULE 2.17(H) the consummation of the
Acquisition Merger as contemplated by this Agreement will not, directly or
indirectly (including, without limitation, as a result of any termination of
employment prior to or following the Effective Time) (i) result in the vesting
or acceleration of the payment of any benefits under any Compensation and
Benefit Plan, (ii) result in any increase in benefits payable or compensation
payable to a participant or service provider under any Compensation and Benefit
Plan, (iii) result in the payment of any severance separation benefit, or (iv)
result in a breach or violation of any Compensation and Benefit Plan.

            (i) No Texas Central Company maintains any compensation plans,
programs or arrangements in which their employees or former employees
participate the payments under which would not reasonably be expected to be
deductible as a result of the limitations under Section 162(m) of the Internal
Revenue Code and the regulations issued thereunder.

            (j) As a result, directly or indirectly, of the Acquisition Merger
as contemplated by this Agreement (including, without limitation, as a result of
any termination of employment prior to or following the Effective Time), neither
BUC nor any Texas Central Company will be obligated to make a payment that would
be characterized as an "excess parachute payment" to an individual who is a
"disqualified individual" (as such terms are defined in Section 280G of the
Internal Revenue

                                    -14-
<PAGE>
Code), without regard to whether such payment is reasonable compensation for
personal services performed or to be performed in the future.

            (k) Neither any Texas Central Company nor any ERISA Affiliate is a
party to, or has made any contribution to or otherwise incurred or could incur
any obligation under any "multiemployer plan", as defined in Section 3(37) of
ERISA.

            (l) There has been no written or oral communication or amendment to
a Compensation and Benefit Plan by any Texas Central Company or any ERISA
Affiliate since January 1, 1998 relating to or changing the participation or
coverage under any such plan in which any of their employees or former employees
participate which would increase the expense of maintaining such plan above the
level of expense incurred with respect to that plan for the most recent fiscal
year included in the Texas Central Financial Statements.

            (m) There are no voluntary employee benefit associations related to
any Compensation and Benefit Plan under Section 501(c)(9) of the Internal
Revenue Code.

            (n) Any guaranteed investment contracts or other funding contracts
with any insurance company that are held by a Compensation and Benefit Plan and
any annuity contracts purchased by such plan was issued by an insurance company
which carried the highest rating from each of D & B, S&P, Best and Moody's
Investor Service, Inc. as of such date the contract was issued, the date hereof
and the Effective Date.

      Section 2.18 LIST OF LOANS. SCHEDULE 2.18 sets forth a true and complete
list, as of December 31, 1998, of all loans (individually, a "Loan" and
collectively, the "Loans") of Texas Central Bank, showing for each such Loan the
outstanding principal balance due, before reduction for any discount. All
currently outstanding Loans of Texas Central Bank, including any current
extensions of any Loan, were solicited, originated and currently exist in
material compliance with all applicable requirements of federal and state law
and regulations promulgated thereunder. The Loans are adequately documented and
each note evidencing a Loan or credit agreement or security instrument related
to a Loan constitutes a valid and binding obligation of the obligor thereunder,
enforceable in accordance with the terms thereof, except where the failure
thereof, individually or in the aggregate, would not have a material adverse
effect on the condition (financial or otherwise), operations or prospects of
Texas Central Bank. For the purposes of this Section, the phrase "enforceable in
accordance with the terms thereof" does not mean that the borrower has the
financial ability to pay a Loan or that any collateral is sufficient to result
in payment of the Loan secured thereby. There are no oral modifications or
amendments or additional agreements related to the Loans that are not reflected
in Texas Central Bank's records, and no claim of defense as to the enforcement
of any Loan has been asserted, and Texas Central Bank is not aware of any acts
or omissions that would give rise to any claim or right of rescission, set off,
counterclaim or defense, except where such claim would not have, either
individually or in the aggregate, a material adverse effect on the condition
(financial or otherwise), operations or prospects of Texas Central Bank.

and any responses by Texas Central Bank to such comments. Texas Central Bank has
a rating of "satisfactory" as of its most recent CRA compliance examination and
knows of no reason why it would not receive a rating of "satisfactory" or better
pursuant to its next CRA compliance examination or why the Department or any
other governmental entity may seek to restrain, delay or prohibit the

under the CRA.

its terms, subject to the effect of bankruptcy, insolvency, reorganization,

provision of, or constitute a default under, any law, or any order, writ,
injunction or decree of any court or other governmental agency, or any contract,
agreement or instrument to which BUC is a party or by which it is bound or
constitute an

                                    -19-
<PAGE>
event which, with the lapse of time or action by a third party, could result in
any default under any of the foregoing or result in the creation of any lien,
charge or encumbrance upon the assets or properties of BUC or upon the BUC
Stock.

      Section 3.6 FINANCIAL REPORTS AND SEC DOCUMENTS; MATERIAL ADVERSE EFFECT.
(a) BUC's Annual Reports on Form 10-K for the fiscal years ended September 30,
1997 and 1998, and all periodic and current reports and definitive proxy
statements filed or to be filed by it subsequent to September 30, 1997 under
Section 13, 14 or 15(d) of the Exchange Act, in the form filed or to be filed
(collectively, "SEC DOCUMENTS") with the SEC, as of the date filed, (a) complied
or will comply in all material respects with the applicable requirements under
the Exchange Act, and (b) did not and will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; and each of the balance sheets or
statements of condition contained in or incorporated by reference into any such
SEC Document (including the related notes and schedules thereto) fairly
presents, or will fairly present, the consolidated financial position of BUC as
of its date, and each of the statements of income and changes in stockholders'
equity and cash flows or equivalent statements in such SEC Documents (including
any related notes and schedules thereto) fairly presents, or will fairly
present, in all material respects, the consolidated results of operations,
changes in stockholders' equity and cash flows, as the case may be, of BUC for
the periods to which they relate, in each case in accordance with generally
accepted accounting principles consistently applied during the periods involved,
except in each case as may be noted therein, subject, in the case of unaudited
financial statements, to normal year-end audit adjustments and the absence of
footnotes.

            (b) Since December 31, 1998, no event has occurred or circumstance
arisen that, individually or taken together with all other facts, circumstances
and events, is reasonably likely to have a material adverse effect with respect
to BUC.

      Section 3.7 LITIGATION; REGULATORY ACTION. Except as set forth in BUC's
SEC Documents (i) no material litigation, claim or other proceeding before any
governmental authority is pending against BUC or any BUC Subsidiary and, to
BUC's knowledge, no such litigation, claim or other proceeding has been
threatened; and (ii) other than routine compliance statements contained in
examinations conducted in the ordinary course, neither BUC nor any BUC
Subsidiary or properties is a party to or is subject to any order, decree,
agreement, memorandum of understanding or similar arrangement with, or a
commitment letter or similar submission to, or extraordinary supervisory letter
from a bank regulatory authority, nor has BUC or any BUC Subsidiary been advised
by a bank regulatory authority that such agency is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting) any
such order, decree, agreement, memorandum of understanding, commitment letter,
supervisory letter or similar submission.

      Section 3.8 COMMUNITY REINVESTMENT ACT. At its most recent regulatory
evaluation of performance under the Community Reinvestment Act (the "CRA"),
BUC's record of performance was deemed to be "outstanding" or "satisfactory,"
and no proceedings are pending or, to the knowledge of BUC, threatened, that
would result in a change in such evaluation. BUC has not

                                    -20-
<PAGE>
received any adverse public comments with respect to its compliance under the
CRA since the date of its most recent regulatory evaluation of its performance
under the CRA.

      Section 3.9 COMPLIANCE WITH LAW. BUC and its subsidiaries have all
material licenses, franchises, permits and other governmental authorizations
that are legally required to enable them to conduct their respective businesses
in the manner presently conducted and are in compliance in all material respects
with all law and regulations applicable to the conduct of their respective
businesses.

      Section 3.10 YEAR 2000 REPRESENTATION. BUC has no reason to believe that
it will receive a rating of less than "satisfactory" on any Year 2000 report of
examination of any regulatory authority. BUC has prepared a plan, including a
good faith preliminary estimate of the anticipated associated costs, for
addressing the issues set forth in the statements of the FFIEC, entitled "Safety
and Soundness Guidelines Concerning the Year 2000 Business Risk," as such issues
affect BUC and such plan is in material compliance with the schedule set forth
in the FFIEC statements. Bank United is in compliance in all material respects
with the Year 2000 Interagency Statements dated June, 1996, May 5, 1997,
December 17, 1997, March 17, 1998, April 10, 1998 and May 13, 1998 issued by the
FFIEC.

correct in all material respects and will not omit any material fact necessary
to make its statements therein, in light of the circumstances in which they were
made, not misleading. BUC will

                                    -21-
<PAGE>
indemnify and hold harmless Texas Central from and against any and all losses,
claims, damages, expenses or liabilities to which Texas Central may become
subject under applicable laws, rules and regulations and will reimburse Texas
Central for any legal or other expenses reasonably incurred by Texas Central in
connection with investigating or defending any actions whether or not resulting
in liability, insofar as such losses, claims, damages, expenses, liabilities or
actions arise out of or are based on any untrue statement or alleged untrue
statement of a material fact contained in any such application or proxy
materials or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary in
order to make the statements therein, in light of the circumstances under which

was made in reliance upon and in conformity with information furnished by BUC in
writing expressly for use therein. BUC agrees, upon the request of Texas
Central, to furnish to it a written letter or statement confirming to the best
of its knowledge the accuracy of the information with respect to BUC and the BUC
Subsidiaries contained in any report or other application or statement referred
to in Sections 4.1 or 4.2 of this Agreement, and confirming that the information

that it will not, without the prior approval of Texas Central, directly or
indirectly solicit any individual who is an employee of any Texas Central
Company on the date the Agreement is terminated to terminate his or her
relationship with such entity in order to become employed by BUC or any of its
subsidiaries; provided, however, that the foregoing shall not apply to (i) the
use of an independent employment agency (so long as the agency was not directed
to solicit a particular individual or class of individuals that could only be
satisfied by employees of a Texas Central Company as of the date the Agreement
is terminated), or (ii) the use of a general solicitation (such as an
advertisement) not specifically directed to employees of a Texas Central
Company.

execution of this Agreement, BUC will file with the SEC a Registration Statement
on Form S-4 under the Securities Act and any other applicable documents (the
"Registration Statement"), relating to the shares of BUC Stock to be delivered
to the shareholders of Texas Central pursuant to this Agreement, and will use
its best efforts to cause such Registration Statement to become effective. At
the time the Registration Statement becomes effective, the Registration
Statement will comply in all material respects with the provisions of the
Securities Act and the published rules and regulations thereunder, and will not
contain any untrue statement of a material fact or omit to state a material fact
required

                                    -22-

misleading, and at the time of mailing thereof to Texas Central's shareholders,
at the time of the Texas Central shareholders' meeting held to approve the
Acquisition Merger and at the Effective Date, the prospectus included as part of
the Registration Statement, as amended or supplemented by any amendment or
supplement filed by BUC (the "Prospectus"), will not contain any untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein not false or misleading; provided, however, that
none of the provisions of this subparagraph shall apply to statements in or
omissions from the Registration Statement or the Prospectus made in reliance
upon and in conformity with information furnished by Texas Central for use in
the Registration Statement or the Prospectus.

      Section 4.5 NASDAQ LISTING. BUC will file all documents required to be

BUC Stock received by them in connection with the Acquisition Merger pursuant to
Rules 144 and 145(d) under the Securities Act if they would otherwise be so
entitled; provided, however, that BUC is otherwise obligated to file such
reports with the SEC.

      Section 4.8 PUBLICATION OF FINANCIAL CONDITION. BUC will publish the
results of thirty (30) days of combined operations of BUC and Texas Central as
soon as practicable after the Effective Date, and no later than thirty (30) days

INDEMNIFICATION. (a) Following the Effective Date, BUC will provide the
directors and officers of Texas Central and its subsidiaries with the same
directors' and officers' liability insurance coverage that BUC provides to
directors and officers of its other banking subsidiaries generally, and, in
addition, for a period of three years will use its best efforts to continue
Texas Central's directors' and officers' liability insurance coverage with
respect to actions occurring prior to the Effective Date and to the extent that
such coverage is obtainable for an aggregate premium not in excess of the
aggregate premium paid by Texas Central for such insurance; provided, that BUC
may at its option elect to replace Texas Central's insurance coverage with
respect to actions occurring prior to the effective date with coverage provided
by other insurers having the same aggregate limits. If the aggregate premium for
such continued coverage would exceed the aggregate premium for such coverage
paid by Texas Central, BUC shall use its best efforts to procure such level of
insurance having the coverage described above as can be obtained for an
aggregate premium equal to the maximum amount paid by Texas Central.

            (b) For six years after the Effective Date, and subject to the
limitations contained in applicable OTS regulations, BUC shall cause the
Surviving Company to indemnify, defend and hold harmless the present and former
officers, directors, employees and agents of Texas Central and its subsidiaries
(each, an "Indemnified Party") against all losses, expenses, claims, damages or
liabilities arising out of actions or omissions occurring on or prior to the
Effective Date (including, without limitation, the transactions contemplated by
this Agreement) to the full extent then permitted under the Texas Business
Corporation Act and by Texas Central's Articles of Incorporation as in effect on
the date hereof, including provisions relating to advances of expenses incurred
in the defense of any action or suit.

      Section 5.19 SUPPLEMENTS TO DISCLOSURE SCHEDULES. From time to time prior
to the Effective Date, Texas Central shall promptly supplement or amend its
Disclosure Schedules to reflect any matter hereafter arising that would make any
representation or warranty set forth in Article II inaccurate. For purposes of
determining (i) the fulfillment of the condition set forth in Section 8.1 as of
the Closing Date and (ii) the accuracy of the representations and warranties
contained in Article II if the Acquisition Merger is not consummated, the
Disclosure Schedules shall be deemed to include only the information contained
therein on the date of this Agreement and shall be deemed to exclude any
information contained in any subsequent supplement or amendment thereto. If the
Acquisition Merger is not consummated, delivery of any supplemental disclosure
schedules will not affect the rights and remedies of the parties hereunder. For
purposes of determining the accuracy of the representations and warranties
contained in Article II or if the Acquisition Merger is consummated, the
Disclosure Schedules shall be deemed to include all information contained in any
supplement or amendment thereto made before the Closing Date. If any supplement
to any Disclosure Schedule shall be delivered within 10 days of the Closing
Date, at the option of BUC the Closing Date may be delayed to permit BUC to have
a period of at least 10 days to consider such supplement.

                                  ARTICLE VI.

                                    CLOSING

      Section 6.1 CLOSING. Subject to the other provisions of this Article VI,
at a mutually acceptable time, on a mutually acceptable date ("Closing Date") as
soon as practicable within a thirty-day period commencing with the latest of the
following dates:

            (i) the receipt of shareholder approval and the last approval from
      any requisite regulatory or supervisory authority and the expiration of
      any statutory or regulatory waiting period which is necessary to effect
      the Acquisition Merger, or

            (ii) if the matters contemplated by this Agreement are being
      contested in any legal proceeding and BUC or Texas Central, pursuant to
      Section 10.1 hereof, have elected to contest the same, then the date that
      such proceeding has been brought to a conclusion favorable, in the
      judgment of each of BUC and Texas Central, to the consummation of the
      Acquisition Merger, or such prior date as each of BUC and Texas Central
      shall elect whether or not such proceeding has been brought to a
      conclusion;

the closing of the Acquisition Merger ("Closing") will take place at which the
parties to this Agreement will exchange certificates, opinions, letters and
other documents provided for under this Agreement in order to effect the
Acquisition Merger and to determine whether any condition exists which would
permit the parties hereto to terminate this Agreement. If no such condition then
exists or if no party elects to exercise any right it may have to terminate this
Agreement, then and thereupon the appropriate parties shall execute such
documents and instruments as may be necessary or appropriate to effect the
Acquisition Merger contemplated by this Agreement.

                                    -29-

      The Closing shall take place at the offices of Bank United in Houston,
Texas, or at such other place to which the parties hereto may mutually agree.

      Section 6.2 EFFECTIVE DATE. Subject to the terms and upon satisfaction of
all requirements of law and the conditions specified in this Agreement
including, among other conditions, the receipt of requisite approval of the
shareholders of Texas Central and the regulatory approvals (or waivers thereof)
of the OTS and the FRB and any other federal or state regulatory agency whose
approval must be received in order to consummate the Acquisition Merger, the
Acquisition Merger shall become effective, and the Effective Date of the
Acquisition Merger shall occur, at the date and time specified in the
certificate approving the Acquisition Merger to be issued by the Secretary of
State of Texas (the "Effective Date"). It is anticipated by BUC and Texas
Central that the Closing and the Effective Date will occur on the same day.

                                  TERMINATION

      Section 7.1 TERMINATION. (a) This Agreement may be terminated by action of
the Board of Directors of BUC or the Board of Directors of Texas Central at any
time prior to the Effective Date if:

            (i) any court of competent jurisdiction in the United States or
      other United States (federal or state) governmental body shall have issued
      an order, decree or ruling or taken any other action restraining,
      enjoining, or otherwise prohibiting the Acquisition Merger and such order,
      decree, ruling or other action shall have been final and non-appealable;

            (ii) any of the transactions contemplated by this Agreement are
      disapproved by any regulatory authority or other person whose approval is
      required to consummate the Acquisition Merger; or

            (iii) the Effective Date shall not have occurred on or before
      September 17, 1999 or such later date as shall have been approved in
      writing by the Boards of Directors of BUC and Texas Central; provided,
      however, that the right to terminate under this Section 7.1(a)(3) shall
      not be available to any party whose failure to fulfill any obligation
      under this Agreement has been the cause of, or has resulted in, the
      failure of the Effective Date to occur on or before such date.

            (iv) This Agreement may be terminated at any time prior to the
      Effective Date by the Board of Directors of Texas Central if (A) BUC shall
      fail to comply in any material respect with any of its covenants or
      agreements contained in this Agreement, or if any of the representations
      or warranties of BUC contained herein shall be untrue in any material
      respect, (B) the Average Value Per Share as calculated in accordance with
      Section 1.6 is below $33.57, or (C) the closing price of the BUC Stock on
      the day immediately prior to the

<PAGE>
      day fixed as the Closing Date shall be less than $32.00. In the event the
      Board of Directors of Texas Central desires to terminate this Agreement as
      provided in Section 7.1(a)(iv)(A) above, such Board of Directors must
      notify BUC in writing of its intent to terminate stating the reason
      therefor. BUC shall have fifteen days from the receipt of such notice to
      cure the alleged breach, inaccuracy or change, subject to the approval of
      Texas Central (which approval shall not be unreasonably delayed or
      withheld).

            (v) This Agreement may be terminated any time prior to the Effective
      Date by BUC if (A) Texas Central shall fail to comply in any material
      respect with any of its covenants or agreements contained in this
      Agreement, or if any of the representations or warranties of Texas Central
      contained herein shall be defective in any material respect, (B) there
      shall have been any change after December 31, 1998 in the assets,
      liabilities (including deposit liabilities) properties, business or
      financial condition of Texas Central, Texas Central Delaware or Texas
      Central Bank which individually or in the aggregate have materially and
      adversely affected the financial condition, results of operation or
      business of Texas Central, or (C) BUC concludes, in its reasonable
      discretion, that BUC will be unable to obtain any regulatory approval
      required in order to consummate the Acquisition Merger. In the event BUC
      desires to terminate this Agreement because of an alleged breach or change
      as provided in Section 7.1(a)(v)(A) or (B) above, BUC must notify Texas
      Central in writing of its intent to terminate stating the cause therefor.
      Texas Central shall have fifteen days from the receipt of such notice to
      cure the alleged breach, inaccuracy or change, subject to the approval of
      BUC (which approval shall not be unreasonably delayed or withheld).

            (vi) This Agreement may be terminated at any time prior to the
      Effective Date with the mutual written consent of BUC and Texas Central.

      Section 7.2 EFFECT OF TERMINATION. In the event of termination of this
Agreement and the abandonment of the Acquisition Merger without breach by any
party hereto, this Agreement shall become void and have no effect, without any
liability on the part of any party or the directors, officers or shareholders of
any corporate party. Nothing contained in this Section 7.2 shall relieve any
party hereto of any liability for a breach of this Agreement; PROVIDED, HOWEVER,
that BUC's remedy for a breach by Texas Central of the representation contained
in Section 2.15 shall be limited to termination of the Agreement and the receipt
of a cash payment from TCBI equal to the actual out of pocket expenses incurred
by BUC in connection with the transactions contemplated hereby, not to exceed
$250,000.

                                  ARTICLE XI.

                               EMPLOYEE MATTERS

      Section 11.1 OFFERS TO TEXAS CENTRAL EMPLOYEES. On or before 15 days prior
to Closing, BUC shall cause Bank United to offer employment, to become effective
as of the Effective Date, to the Employees of Texas Central or its subsidiaries
employed as of, or on, the Effective Date (the "Employees") whom Bank United
wishes to employ and give notice to Texas Central of the names of the Employees
whom BUC does not wish to employ. To the extent consistent with Bank United's
existing compensation structure for comparable positions and comparable officer
titles and its current policies regarding officer titles, all Employees offered
employment by Bank United shall be offered employment at base wages and salaries
no less favorable than the wages and salaries currently being received by such
Employees to such Employees and in positions with comparable responsibilities
and officer titles, and, unless agreed upon by such Employee before the
Effective Date, within a reasonable geographic proximity to such Employee's
current work location. BUC shall be responsible for advising Employees of the

relating thereto, but Texas Central shall be allowed to review and promptly
approve any communication that refers to any of Texas Central's benefits or
policies prior to its distribution.

      Section 11.2 CREDIT FOR SERVICE WITH TEXAS CENTRAL. All Employees who are
offered and accept employment with BUC as of the Effective Date shall be
eligible to participate in the employee benefit plans and other fringe benefits
of BUC on the same basis as such plans and benefits are offered to employees of
BUC with comparable positions with BUC. To the extent possible under its
employee benefit plans, BUC shall credit such Employees for their length of
service with Texas Central for purposes of eligibility and vesting under each
employee benefit and fringe benefit plan to be provided by BUC to such
Employees, to the same extent such service was recognized under a similar plan
of Texas Central, based on information provided by Texas Central. For purposes
of this Section 11.2, "employee benefit plans and other fringe benefits"
includes, without limitation, health insurance benefits (medical and dental),
disability, life and accident insurance, sickness benefits, employee loans and
banking privileges, but does not include, if any, the incentive compensation,
pension, profit sharing, retirement and post retirement welfare benefits, and
vacation plans of Texas Central. If BUC offers a salary continuation or similar
program for employees unable to work for medical reasons, the Employees who are
offered and accept employment with BUC shall be credited under any program of
BUC with at least the number of sickness benefit days (up to a maximum of 22
calendar days) accrued under Texas Central's program at the Effective Date.

      Section 11.3 VACATION POLICY. Immediately prior to the Effective Date,
Texas Central shall pay all vacation accrued and not taken by Employees in
accordance with Section 5.14 and 12.2. In the calendar year in which the
Effective Date occurs, Employees who are offered and accept employment with BUC
shall be eligible to earn the annual vacation amount Employees would be eligible
to earn as employees of BUC or a BUC Subsidiary, without giving credit for the
Employees length of service with Texas Central. In subsequent calendar years,
Employees will be eligible to earn vacation days according to the schedule
specified in BUC's vacation policy.

Bank United Corp.

Ladies and Gentlemen:

I am General Counsel of Bank United Corp., a Delaware corporation (the
"Company"). The Company proposes to offer up to 710,000 shares of its Class A
Common Stock, par value $.01 per share (the "Common Stock"), to the shareholders
of Texas Central Bancshares, Inc. ("TCBI") in connection with the merger of BUC
Acquisition Corporation II, a wholly owned subsidiary of the Company ("Newco"),
with and into TCBI pursuant to the terms of an Agreement and Plan of
Reorganization dated as of March 23, 1999 by and among the Company, Newco, and
TCBI (the "Merger Agreement"). The Company has filed a Registration Statement on
Form S-4 ("Registration Statement") with the Securities and Exchange Commission
under the Securities Act of 1933, as amended, with respect to the Common Stock
to be issued pursuant to the Merger Agreement.

As General Counsel of the Company, I am familiar with the facts relating to this
opinion and have made such investigations of law as I have deemed necessary and
relevant as a basis hereof. I have assumed the genuineness of all signatures,
the authenticity of all documents, certificates and records submitted to me as
originals, the conformity to original documents, certificates and records of all
documents, certificates and records submitted to me as copies, and the
truthfulness of all statements of fact contained therein. Based on the
foregoing, and subject to the limitations set forth herein, and having due
regard for such legal considerations as I deem relevant, I am of the opinion
that, upon issuance pursuant to the terms of the Merger Agreement, the Common
Stock will be legally issued, fully paid and non-assessable. The foregoing
opinion is based on and is limited to the corporate laws of the State of
Delaware and the relevant laws of the United States of America, and I render no
opinion with respect to the laws of any other jurisdiction.

I hereby consent to the filing of this opinion with the Securities and Exchange
Commission as an exhibit to the Registration Statement and to the use of my name
therein.

                                    Very truly yours,

                                    BANK UNITED CORP.

                            STOCK OPTION AGREEMENT


      This Stock Option Agreement dated as of March 23, 1999 (the "Agreement"),
by and between Texas Central Bancshares, Inc., a Texas corporation ("Issuer"),
and Bank United Corp., a Delaware corporation ("Grantee").

                                R E C I T A L S

      A. Grantee, BUC Acquisition Corp. II, a wholly owned subsidiary of Grantee
("Sub"), and Issuer have entered into an Agreement and Plan of Reorganization
dated as of the date hereof (the "Reorganization Agreement"; capitalized terms
used but not defined herein have the meanings set forth in the Reorganization
Agreement) providing for, among other things, the merger of Sub with and into
Issuer, with Issuer as the surviving corporation in the merger and becoming a
wholly owned subsidiary of Grantee (the "Acquisition Merger"); and

      B. As a condition and inducement to Grantee's willingness to enter into
the Reorganization Agreement, Grantee has requested that Issuer agree, and
Issuer has agreed, to grant Grantee the Option (as defined below).

      NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, Issuer
and Grantee agree as follows:

      1. GRANT OF OPTION. Subject to the terms and conditions set forth herein,
Issuer hereby grants to Grantee an irrevocable option (the "Option") to purchase
up to 60,464 (as adjusted as set forth herein) shares (the "Option Shares") of
common stock, par value $1.00 per share ("Issuer Common Stock"), of Issuer at a
purchase price of $49.83 (as adjusted as set forth herein) per Option Share (the
"Purchase Price"); PROVIDED, HOWEVER, that in no event shall the number of
Option Shares for which the Option is exercisable exceed 19.9% of the issued and
outstanding shares of Issuer Common Stock excluding, for purposes of this
calculation, any shares subject to or issued pursuant to the Option.

      2. EXERCISE OF OPTION. (a) Subject to the provisions of Section 2(f),
Grantee may exercise the Option, with respect to any or all of the Option
Shares, at any time or from time to time, but only following the occurrence of a
Purchase Event, as defined below; PROVIDED, HOWEVER, that (i) except as provided
in the last sentence of this Section 2(a), the Option will terminate and be of
no further force and effect upon the earliest to occur of (A) the Effective
Time, (B) fifteen (15) business days after the first occurrence of a Purchase
Event, and (C) termination of the Reorganization Agreement in accordance with
its terms prior to the occurrence of a Purchase Event, and (ii) any purchase of
Option Shares upon exercise of the Option will be subject to compliance with the
applicable regulations of the Federal Reserve Board, the Office of Thrift
Supervision and other agencies having jurisdiction over the Issuer's sale, and
the Grantee's acquisition, of the Option Shares, and the obtaining or making of
any consents, approvals, orders, notifications, filings or authorizations, the
failure of which to have obtained or made would have the effect of making the
issuance of Option Shares to Grantee illegal (the "Regulatory Approvals").
Notwithstanding the
<PAGE>
termination of the Option, Grantee will be entitled to purchase the Option
Shares or exercise its Cash-Out Right (as defined below) if it has given notice
of same in accordance with the terms hereof prior to the termination of the
Option and the termination of the Option will not affect any rights hereunder or
under the Reorganization Agreement which by their terms do not terminate or
expire prior to or as of such termination.

            (b) As used herein, a "Purchase Event" means any of the following
events:

                  (i) Without Grantee's prior written consent, Issuer shall have
      authorized, recommended, publicly proposed or publicly announced an
      intention to authorize, recommend or propose, or entered into an agreement
      with any person (other than Grantee or any subsidiary of Grantee) to
      effect an Acquisition Transaction (as defined below). As used herein, the
      term "Acquisition Transaction" shall mean (A) a merger, consolidation,
      statutory share exchange or similar transaction involving Issuer or any of
      its subsidiaries (other than transactions solely between Issuer's
      subsidiaries), (B) the disposition, by sale, lease, exchange or otherwise,
      of assets of Issuer or any of its subsidiaries representing in either case
      10% or more of the consolidated assets of Issuer and its subsidiaries, or
      (C) the issuance, sale or other disposition of (including by way of
      merger, consolidation, share exchange or any similar transaction)
      securities representing 20% or more of the voting power of Issuer or any
      of its subsidiaries; or

                  (ii) any person (other than Grantee or any subsidiary of
      Grantee) shall have acquired beneficial ownership (as such term is defined
      in Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as
      amended (the "Exchange Act")) of, or the right to acquire beneficial
      ownership of, or any "group" (as such term is defined under the Exchange
      Act) shall have been formed which beneficially owns or has the right to
      acquire beneficial ownership of, 30% or more (or, if such person or group
      is the beneficial owner of 30% or more on the date hereof, such person or
      group acquires an additional 5% or more) of the voting power of Issuer or
      any of its subsidiaries ;PROVIDED, that the acquisition of beneficial
      ownership, or a right to acquire beneficial ownership, by any person or
      group (other than Grantee or a subsidiary of Grantee) of 30% or more (or,
      if such person or group is the beneficial owner of 30% or more on the date
      hereof, such person or group shall acquire an additional 5% or more) of
      the voting power of the Issuer or any of its subsidiaries that results
      from the acquisition of such voting power by such person or group after
      the date hereof pursuant to the last will or laws of intestate succession
      of a shareholder of Issuer shall not be deemed a Purchase Event hereunder
      so long as, after giving effect to such acquisition, at least two-thirds
      of the voting power of the Issuer remains subject to the several Voting
      Agreements and Irrevocable Proxies of even date herewith by and between
      certain shareholders of the Issuer and the Grantee.

            (c) As used herein, a "Preliminary Purchase Event" means any of the
following events:

                                   -2-
<PAGE>
                  (i) any person (other than Grantee or any subsidiary of
      Grantee) shall have commenced (as such term is defined in Rule 14d-2 under
      the Exchange Act) or shall have filed a registration statement under the
      Securities Act of 1933, as amended (the "Securities Act"), with respect to
      a tender offer or exchange offer to purchase any shares of Issuer Common
      Stock such that, upon consummation of such offer, such person would
      beneficially own 30% or more of the then outstanding shares of Issuer
      Common Stock (such an offer being referred to herein as a "Tender Offer"
      or an "Exchange Offer," respectively); or

                  (ii) the holders of Issuer Common Stock shall not have
      approved the Reorganization Agreement at the meeting of such shareholders
      held for the purpose of voting on the Reorganization Agreement, or such
      meeting shall not have been held or shall have been canceled prior to
      termination of the Reorganization Agreement, or the Issuer's Board of
      Directors shall have withdrawn or modified in a manner adverse to Grantee
      the recommendation of Issuer's Board of Directors with respect to the
      Reorganization Agreement, in each case, after it shall have been publicly
      announced that any person (other than Grantee or any subsidiary of
      Grantee) shall have (A) made, or disclosed an intention to make, a
      proposal to engage in an Acquisition Transaction, (B) commenced a Tender
      Offer or filed a registration statement under the Securities Act with
      respect to an Exchange Offer or (C) filed an application (or given a
      notice), whether in draft or final form, under any applicable law or
      regulation, including without limitation, the Bank Holding Company Act of
      1956, the Bank Merger Act, the Change in Bank Control Act of 1978 or the
      savings and loan holding company provisions of the Home Owner's Loan Act
      for approval to engage in an Acquisition Transaction.

As used in this Agreement, the term "person" shall have the meaning specified in
Section 3(a)(9) and 13(d)(3) of the Exchange Act.

            (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Preliminary Purchase Event or Purchase Event, it being
understood that the giving of such notice by Issuer shall not be a condition to
the right of Grantee to exercise the Option.

            (e) In the event that Grantee is entitled to and wishes to exercise
the Option, it will send to Issuer a written notice (an "Exercise Notice"; the
date of which being herein referred to as the "Notice Date") to that effect and
which Exercise Notice also specifies the number of Option Shares, if any,
Grantee wishes to purchase pursuant to this Section 2(b), the number of Option
Shares, if any, with respect to which Grantee wishes to exercise its Cash-Out
Right (as defined herein) pursuant to Section 6(c), the denominations of the
certificate or certificates evidencing the Option Shares which Grantee wishes to
purchase pursuant to this Section 2(b) and a date (an "Option Closing Date"),
subject to the following sentence, not earlier than seven business days nor
later than 20 business days from the Notice Date for the closing of such
purchase (an "Option Closing"). Any Option Closing will be at an agreed location
and time in Houston, Texas on the applicable Option Closing Date or at such
later date as may be necessary so as to comply with the first sentence of
Section 2(a).

                                    -3-
<PAGE>
            (f) Notwithstanding anything to the contrary contained herein, any
exercise of the Option and purchase of Option Shares shall be subject to
compliance with applicable laws and regulations, which may prohibit the purchase
of all the Option Shares specified in the Exercise Notice without first
obtaining or making the required Regulatory Approvals. In such event, if the
Option is otherwise exercisable and Grantee wishes to exercise the Option, the
Option may be exercised in accordance with Section 2(b) and Grantee shall
acquire the maximum number of Option Shares specified in the Exercise Notice
that Grantee is then permitted to acquire under the applicable laws and
regulations, and if Grantee thereafter obtains the Regulatory Approvals to
acquire the remaining balance of the Option Shares specified in the Exercise
Notice, then Grantee shall be entitled to acquire such remaining balance. Issuer
agrees to use its reasonable efforts to assist Grantee in obtaining the
Regulatory Approvals.

      In the event (i) Grantee receives official notice that a Regulatory
Approval required for the purchase of any Option Shares will not be issued or
granted or (ii) such Regulatory Approval has not been issued or granted within
six months of the date of the Exercise Notice, Grantee shall have the right to
exercise its Cash-Out Right pursuant to Section 6(c) with respect to the Option
Shares for which such Regulatory Approval will not be issued or granted or has
not been issued or granted.

      3. PAYMENT AND DELIVERY OF CERTIFICATES. (a) At any Option Closing,
Grantee will pay to Issuer in immediately available funds by wire transfer to a
bank account designated in writing by Issuer an amount equal to the Purchase
Price multiplied by the number of Option Shares to be purchased at such Option
Closing plus the amount of any transfer, stamp or other similar taxes or charges
imposed in connection therewith.

            (b) At any Option Closing, simultaneously with the delivery of
immediately available funds as provided in Section 3(a), Issuer will deliver to
Grantee a certificate or certificates representing the Option Shares to be
purchased at such Option Closing, which Option Shares will be free and clear of
all liens, claims, charges and encumbrances of any kind whatsoever. If at the
time of issuance of Option Shares pursuant to an exercise of the Option
hereunder, Issuer shall have issued any securities similar to rights under a
stockholder rights plan, then each Option Share issued pursuant to such exercise
will also represent such a corresponding right with terms substantially the same
as and at least as favorable to Grantee as are provided under any such
stockholder rights plan then in effect.

            (c) Certificates for the Option Shares delivered at an Option
Closing will have typed or printed thereon a restrictive legend which will read
substantially as follows:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
      ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
      AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
      TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT DATED AS OF MARCH 23,
      1999, A COPY OF WHICH MAY BE OBTAINED FROM

                                    -4-
<PAGE>
      THE SECRETARY OF TEXAS CENTRAL BANCSHARES, INC. AT ITS PRINCIPAL EXECUTIVE
      OFFICES."

It is understood and agreed that (i) the reference to restrictions arising under
the Securities Act in the above legend will be removed by delivery of substitute
certificate(s) without such reference if such Option Shares have been registered
pursuant to the Securities Act, such Option Shares have been sold in reliance on
and in accordance with Rule 144 under the Securities Act or Grantee has
delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion
of counsel in form and substance reasonably satisfactory to Issuer and its
counsel, to the effect that such legend is not required for purposes of the
Securities Act and (ii) the reference to restrictions pursuant to this Agreement
in the above legend will be removed by delivery of substitute certificate(s)
without such reference if the Option Shares evidenced by certificate(s)
containing such reference have been sold or transferred in compliance with the
provisions of this Agreement under circumstances that do not require the
retention of such reference.

      4. REPRESENTATIONS AND WARRANTIES OF ISSUER. Issuer hereby represents and
warrants to Grantee that (i) Issuer has taken all necessary corporate and other
action to authorize and reserve and, subject to the receipt of any required
Regulatory Approvals, to permit it to issue the Option Shares; (ii) at all times
from the date hereof until the obligation to deliver Option Shares upon the
exercise of the Option terminates, Issuer shall have reserved for issuance, upon
exercise of the Option, shares of Issuer Common Stock necessary for Grantee to
exercise the Option, and Issuer will take all necessary corporate action to
authorize and reserve for issuance all additional shares of Issuer Common Stock
or other securities which may be issued pursuant to Section 6 upon exercise of
the Option; and (iii) the shares of Issuer Common Stock to be issued upon due
exercise of the Option, including all additional shares of Issuer Common Stock
or other securities which may be issuable upon exercise of the Option or any
other securities which may be issued pursuant to Section 6, upon issuance
pursuant hereto, will be duly and validly issued, fully paid and nonassessable,
and will be delivered free and clear of all liens, claims, charges and
encumbrances of any kind or nature whatsoever, including without limitation any
preemptive rights of any stockholder of Issuer.

      5. REPRESENTATION AND WARRANTY OF GRANTEE. Grantee hereby represents and
warrants to Issuer that any Option Shares or other securities acquired by
Grantee upon exercise of the Option will be acquired for investment and will not
be transferred or otherwise disposed of except in a transaction registered, or
exempt from registration, under the Securities Act.

      6. ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC. (a) In the event of any
change in Issuer Common Stock by reason of a stock dividend, split-up, merger,
recapitalization, combination, exchange of shares, or similar transaction, the
type and number of shares or securities subject to the Option, and the Purchase
Price thereof, will be adjusted appropriately, and proper provision will be made
in the agreements governing such transaction, so that Grantee will receive upon
exercise of the Option the number and class of shares or other securities or
property that Grantee would have received in respect of Issuer Common Stock if
the Option had been exercised immediately prior to such event or the record date
therefor, as applicable. Subject to Section 1, and without limiting the parties'
relative rights and obligations under the Reorganization Agreement, if any
additional shares

                                    -5-
<PAGE>
of Issuer Common Stock are issued after the date of this Agreement (other than
pursuant to an event described in the first sentence of this Section 6(a)), the
number of shares of Issuer Common Stock subject to the Option will be adjusted
so that, after such issuance, it equals 19.9% of the number of shares of Issuer
Common Stock then issued and outstanding, without giving effect to any shares
subject to or issued pursuant to the Option.

            (b) Without limiting the parties' relative rights and obligations
under the Reorganization Agreement, in the event that Issuer enters into an
agreement (i) to consolidate with or merge into any person, other than Grantee
or one of its subsidiaries, and Issuer will not be the continuing or surviving
corporation in such consolidation or merger, (ii) to permit any person, other
than Grantee or one of its subsidiaries, to merge into Issuer and Issuer will be
the continuing or surviving corporation, but in connection with such merger, the
shares of Issuer Common Stock outstanding immediately prior to the consummation
of such merger will be changed into or exchanged for stock or other securities
of Issuer or any other person or cash or any other property, or the shares of
Issuer Common Stock outstanding immediately prior to the consummation of such
merger will, after such merger, represent less than 50% of the outstanding
voting securities of the merged company, or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person, other than Grantee or one
of its subsidiaries, then, and in each such case, the agreement governing such
transaction will make proper provision so that the Option will, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option with identical terms
appropriately adjusted to acquire the number and class of shares or other
securities or property that Grantee would have received in respect of Issuer
Common Stock if the Option had been exercised immediately prior to such
consolidation, merger, sale, or transfer, or the record date therefor, as
applicable and make any other necessary adjustments.

            (c) If, at any time during the period commencing on a Purchase Event
and ending on the termination of the Option in accordance with Section 2,
Grantee sends to Issuer an Exercise Notice indicating Grantee's election to
exercise its right (the "Cash-Out Right") pursuant to this Section 6(c), then
Issuer shall pay to Grantee, on the Option Closing Date, in exchange for the
cancellation of the Option with respect to such number of Option Shares as
Grantee specifies in the Exercise Notice: (i) if the Purchase Event is one
specified in Section 2(b)(i)(A) or Section 2(b)(i)(B), an amount in cash equal
to the product obtained by multiplying the number of Option Shares specified in
the Exercise Notice by the difference between (A) the highest price per share
paid or to be paid for the Issuer Common Stock in the Purchase Event and (B) the
Purchase Price; or (ii) in the case of any other Purchase Event, an amount in
cash equal to the number of Option Shares specified in the Exercise Notice
multiplied by the difference between (Y) the product obtained by multiplying the
number of shares of BUC common stock into which a share of TCBI common stock
would have been converted in the merger by the average of the daily reported
closing sales prices for a share of the Class A Common Stock of Grantee in The
NASDAQ Stock Market National Market for the twenty successive trading days
ending on the trading day that is one trading day prior to the date of the
Exercise Notice and (Z) the Exercise Price. Notwithstanding the termination of
the Option, Grantee will be entitled to exercise its rights under this Section
6(c) if it has exercised such rights in accordance with the terms hereof prior
to the termination of the Option.

                                    -6-
<PAGE>
      7. LISTING. If Issuer Common Stock or any other securities to be acquired
upon exercise of the Option are then listed on any national securities exchange
or interdealer securities quotation system), Issuer, upon the request of
Grantee, will promptly file an application to list the shares of Issuer Common
Stock or other securities to be acquired upon exercise of the Option on any such
national securities exchange or interdealer securities quotation system) and
will use reasonable efforts to obtain approval of such listing as promptly as
practicable.

      8. LOSS OR MUTILATION. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered will constitute an
additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed, or mutilated shall at any time be
enforceable by anyone.

      9.    MISCELLANEOUS.

            (a) EXPENSES. Each of the parties hereto will bear and pay all costs

            (b) AMENDMENT. This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c) EXTENSION; WAIVER. Any agreement on the part of a party to waive
any provision of this Agreement, or to extend the time for performance, will be
valid only if set forth in an instrument in writing signed on behalf of such
party. The failure of any party to this Agreement to assert any of its rights
under this Agreement or otherwise will not constitute a waiver of such rights.

            (d) ENTIRE AGREEMENT; NO THIRD-PARTY BENEFICIARIES. This Agreement
and the Reorganization Agreement (including the documents and instruments
attached thereto as exhibits or schedules or delivered in connection therewith)
(i) constitute the entire agreement, and supersede all prior agreements and
understandings, both written and oral, between the parties with respect to the
subject matter of this Agreement, and (ii) are not intended to confer upon any
person other than the parties any rights or remedies.

            (e) GOVERNING LAW. This Agreement will be governed by, and construed
in accordance with, the laws of the State of Texas, regardless of the laws that
might otherwise govern under applicable principles of conflict of laws thereof.

            (f) NOTICES. All notices, requests, claims, demands, and other
communications under this Agreement shall be sent in the manner and to the
addresses set forth in the Reorganization Agreement.

            (g) ASSIGNMENT. Neither this Agreement, the Option nor any of the
rights, interests, or obligations under this Agreement may be assigned or
delegated, in whole or in part, by operation of law or otherwise, by Issuer or
Grantee without the prior written consent of the other. Any assignment or
delegation in violation of the preceding sentence will be void. Subject to the
first and second sentences of this Section 11(g), this Agreement will be binding
upon, inure to the benefit of, and be enforceable by, the parties and their
respective successors and permitted assigns.

            (h) FURTHER ASSURANCES. In the event of any exercise of the Option
by Grantee, Issuer and Grantee will execute and deliver all other documents and
instruments and take all other actions that may be reasonably necessary in order
to consummate the transactions provided for by such exercise.

            (i) ENFORCEMENT. The parties agree that irreparable damage would
occur and that the parties would not have any adequate remedy at law in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties will be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any Federal court located in the
State of Texas or in Texas state court, the foregoing being in addition to any
other remedy to which they are entitled at law or in equity. In addition, each
of the parties hereto (i) consents to submit itself to the personal jurisdiction
of any Federal court located in the State of Texas or any Texas state court in
the event any dispute arises out of this Agreement or any of the transactions
contemplated by this Agreement, (ii) agrees that it will not attempt to deny or
defeat such personal jurisdiction by motion or other request for leave from any
such court, and (iii) agrees that it will not bring any action relating to this
Agreement or any of the transactions contemplated by this Agreement in any court
other than a Federal court sitting in the State of Texas or a Texas state court.

            (j) SEVERABILITY. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

                                    -2-
<PAGE>
actions: (A) any Company Acquisition Transaction and (B) to the extent that such

outstanding Shareholder's Shares entitled to vote, does hereby make, constitute
and appoint BUC, or any nominee of BUC, each with full power of substitution and

proxy (the "Proxy"), for and in Shareholder's name, place and stead, to demand
that the Secretary of the Company call a special meeting of the Shareholders of
the Company for the purpose of considering any action related to the
Reorganization Agreement or the Reorganization and to vote such Shareholder's
Shares as its Proxy, at every annual, special or adjourned meeting of the
Shareholders of the Company, including the right to sign its name (as
Shareholder) to any consent, certificate or other document relating to the
Company that the laws of the State of Texas may permit or require, with respect
to any matters as to which the Shareholder is required to vote in accordance
with Section 2(a). The Proxy may not exercise this proxy on any other matter.
The Shareholder may vote the Shareholder's Shares on all such other matters.
THIS PROXY AND POWER OF ATTORNEY IS IRREVOCABLE AND COUPLED WITH AN INTEREST.
The Shareholder represents that any proxies heretofore given in respect of the
Shareholder's Shares are not irrevocable, and that any such proxies are hereby
revoked.

            (c) The Shareholder hereby permits BUC and Merger Sub to publish and
disclose in the Registration Statement (including all documents and schedules
filed with the SEC) and in the Proxy Statement its identity and ownership of the
Shareholder's Shares and the nature of its commitments, arrangements and
understandings under this Agreement; PROVIDED, HOWEVER, that the BUC and Merger
Sub shall afford to the Shareholder a reasonable opportunity to review and
comment upon the disclosure regarding the foregoing matters prior to the filing
thereof with the SEC.

      3. COVENANTS, REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDER. The
Shareholder hereby represents and warrants to, and covenants and agrees with,
BUC and Merger Sub as follows:

            (a) OWNERSHIP. As of the date of this Agreement, the Shares set
forth on Schedule I hereto constitute all of the issued and outstanding Shares
owned of record or Beneficially Owned by the Shareholder. Except as otherwise
set forth in Schedule I, the Shareholder has sole power of disposition, sole
power to demand appraisal rights and sole power to vote upon and agree

                                    -3-
<PAGE>
to all of the matters set forth in this Agreement, in each case with respect to
all of the Shares set forth on Schedule I hereto, with no material limitations,
qualifications or restrictions on such rights, subject to applicable securities
laws and the terms of this Agreement and the Shareholders Agreement.

            (b) POWER; BINDING AGREEMENT. The Shareholder has the legal
capacity, power and authority to enter into and perform all of the Shareholder's
obligations under this Agreement. This Agreement has been duly and validly
executed and delivered by the Shareholder and constitutes a valid and binding
agreement of the Shareholder, enforceable against the Shareholder in accordance
with its terms, subject to applicable bankruptcy, insolvency, moratorium or
other similar laws relating to creditors' rights and general principles of
equity. There is no beneficiary or holder of a voting trust certificate or other
interest of any trust of which the Shareholder is trustee whose consent is
required for the execution and delivery of this Agreement or the consummation by
the Shareholder of the transactions contemplated hereby. If the Shareholder is
married and the Shareholder's Shares constitute community property, this
Agreement has been duly authorized, executed and delivered by, and constitutes a
valid and binding agreement of, the Shareholder's spouse, enforceable against
such person in accordance with its terms, subject to applicable bankruptcy,
insolvency, moratorium or other similar laws relating to creditors' rights and
general principles of equity.

            (c) NO CONFLICTS. No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by the Shareholder and the
consummation by the Shareholder of the transactions contemplated hereby, except
where the failure to obtain such consent, permit, authorization, approval or
filing would not interfere in any material respect with the Shareholder's
ability to perform his obligations hereunder, and none of the execution and
delivery of this Agreement by the Shareholder, the consummation by the
Shareholder of the transactions contemplated hereby or compliance by the
Shareholder with any of the provisions hereof shall (i) result in a violation or
breach of, or constitute (with or without notice or lapse of time or both) a
default (or give rise to any third party right of termination, cancellation,
material modification or acceleration) under any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, license, contract,
commitment, arrangement, understanding, agreement or other instrument or
obligation of any kind to which the Shareholder is a party or by which the
Shareholder or any of his properties or assets may be bound, or (ii) violate any
order, writ, injunction, decree, judgment, order, statute, rule or regulation
applicable to the Shareholder or any of his properties or assets, in each such
case except to the extent that any conflict, breach, default or violation would
not interfere in any material respect with the ability of the Shareholder to
perform its obligations hereunder.

            (d) NO ENCUMBRANCES. At all times hereafter during the term hereof,
all of the Shareholder's Shares (excluding Shares identified in Schedule I
hereto as Shares with respect to which Shareholder does not possess sole power
to dispose or direct the disposition) will be held by the Shareholder, or by a
nominee or custodian for the benefit of such Shareholder, free and clear of all
liens, claims, security interests, proxies, voting trusts or agreements,
understandings or arrangements or any other encumbrances whatsoever, except for
any liens, claims, understandings or arrangements that do not limit or impair in
any material respect Shareholder's ability to perform

                                    -4-
<PAGE>
his obligations under this Agreement, and subject to applicable securities laws
and the terms of this Agreement and the Shareholders Agreement.

            (e) NO SOLICITATION. The Shareholder shall not take any action which
is described in Section 5.6 of the Reorganization Agreement as an action which
the Company is prohibited from authorizing or permitting its officers, directors
or employees to take or which the TCBI Shareholders are prohibited from taking.

            (f) RESTRICTION ON TRANSFER AND PROXIES; NON-INTERFERENCE. From and
after the date of this Agreement and ending as of the first to occur of the
Effective Time or the Termination Date, the Shareholder shall not, and shall
cause each of his Affiliates who Beneficially Own any of the Shareholder's
Shares not to, directly or indirectly, without the consent of BUC: (i) offer for
sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose of,
or enter into any contract, option or other arrangement or understanding with
respect to or consent to the offer for sale, sale, transfer, tender, pledge,
encumbrance, assignment or other disposition of, any or all of the Shareholder's
Shares, or any interest therein, (ii) except as provided in this Agreement,
grant any proxies or powers of attorney, deposit any Shareholder's Shares into a
voting trust or enter into a voting agreement with respect to any Shareholder's
Shares, (iii) enter into any agreement or arrangement providing for any of the
actions described in clause (i) or (ii) above or (iv) take any action that could
reasonably be expected to have the effect of preventing or disabling the
Shareholder from performing the Shareholder's obligations under this Agreement.

            (g) WAIVER OF AND AGREEMENT NOT TO ASSERT APPRAISAL RIGHTS. The
Shareholder hereby waives and agrees not to assert, and shall cause any of its
Affiliates who hold of record any of the Shareholder's Shares to waive and not
to assert, any appraisal rights with respect to the Acquisition Merger that the
Shareholder or such Affiliate may now or hereafter have with respect to any
Shares (or any other shares of capital stock of the Company that the Shareholder
shall hold of record at the time that Shareholder may be entitled to assert
appraisal rights with respect to the Merger) whether pursuant to Article 5.11 of
the TBCA or otherwise.

            (h) FURTHER ASSURANCES. From time to time, at BUC's request and
without further consideration, the Shareholder shall execute and deliver such
additional documents reasonably requested by BUC as may be necessary or
desirable to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement.

            (i) RIGHTS OF FIRST REFUSAL. Neither the Shareholder nor any of its
Affiliates have any rights of first refusal, preemptive rights or similar rights
to purchase Shares issuable by the Company pursuant to the Texas Central Stock
Option.

      4. COVENANTS, REPRESENTATIONS AND WARRANTIES OF BUC AND MERGER SUB. BUC
and Merger Sub hereby represent, warrant and covenant to the Shareholder that:

            (a) ORGANIZATION, STANDING AND CORPORATE POWER. Each of BUC, Merger

<PAGE>
their respective jurisdiction of incorporation, with adequate corporate power
and authority to own its properties and carry on its business as presently

enter into and perform all of its obligations under this Agreement and to
consummate the transactions contemplated hereby.

            (b) EXECUTION, DELIVERY AND PERFORMANCE BY BUC AND MERGER SUB. The

the transactions contemplated by this Agreement. This Agreement constitutes the
valid and binding obligations of BUC and Merger Sub and is enforceable against
BUC and Merger Sub in accordance with its terms, except as enforceability may be
subject to bankruptcy, insolvency, reorganization, moratorium or other similar
laws relating to or affecting creditors' rights generally.

      5. STOP TRANSFER. From and after the date of this Agreement and ending as
of the first to occur of the Effective Time or the Termination Date, Shareholder
will not request that the Company register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any of the
Shareholder's Shares (excluding shares identified in Schedule I as Shares with
respect to which Shareholder does not possess sole power to dispose or direct
the disposition), or as otherwise contemplated hereby.

      6. RECAPITALIZATION. In the event of a stock dividend or distribution, or
any change in the Shares (or any class thereof) by reason of any split-up,
recapitalization, combination, exchange of shares or the like, the term "Shares"
shall include, without limitation, all such stock dividends and distributions
and any shares into which or for which any or all of the Shares (or any class
thereof) may be changed or exchanged as may be appropriate to reflect such
event.

      7. SHAREHOLDER CAPACITY. The Shareholder does not make any agreement or
understanding herein, in his capacity as a director or officer of the Company,

binding upon any Person to which legal or beneficial ownership of such Shares
shall pass, whether by operation of Law or otherwise, including without

      11.   MISCELLANEOUS.

            (a) ENTIRE AGREEMENT. This Agreement constitutes the entire
agreement between the parties with respect to the subject matter hereof and

between the parties with respect to the subject matter hereof.

            (b) AMENDMENTS, WAIVERS, ETC. This Agreement may not be amended,
changed, supplemented, waived or otherwise modified or terminated, except upon
the execution and delivery of a written agreement executed by the parties
hereto.

            (c) NOTICES. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given (and shall be
deemed to have been duly received if so given) by hand delivery, telegram, telex
or telecopy, or by mail (registered or certified mail, postage prepaid, return
receipt requested) or by any courier service, such as Federal Express, providing
proof of delivery. All communications hereunder shall be delivered to the
respective parties at the following addresses or the addresses set forth on the
signature pages hereto:

             If to Shareholder:
                              ___________________________________
                              ___________________________________
                              ___________________________________

             If to BUC or Merger Sub:
                              Bank United Corp.
                              3200 Southwest Freeway, Suite 1600
                              Houston, Texas 77027
                              Attention: General Counsel


or to such other address as the person to whom notice is given may have
previously furnished to the others in writing in the manner set forth above.

            (d) SEVERABILITY. Whenever possible, each provision or portion of
any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable

                                    -7-
<PAGE>
law, but if any provision or portion of any provision of this Agreement is held
to be invalid, illegal or unenforceable in any respect under any applicable law
or rule in any jurisdiction, then such invalidity, illegality or
unenforceability will not affect any other provision or portion of any provision
in such jurisdiction, and this Agreement will be reformed, construed and
enforced in such jurisdiction as if such invalid, illegal or unenforceable
provision or portion of any provision had never been contained herein.

            (e) SPECIFIC PERFORMANCE. Each of the parties hereto recognizes and
acknowledges that a breach by the Shareholder of any covenants or agreements
contained in this Agreement will cause BUC and Merger Sub to sustain damages for
which they would not have an adequate remedy at law for money damages, and
therefore each of the parties hereto agrees that, in the event of any such
breach, BUC or Merger Sub shall be entitled to seek the remedy of specific
performance of such covenants and agreements and injunctive and other equitable
relief, without the necessity of posting bond or proving actual damages, in
addition to any other remedy to which they may be entitled, at law or in equity.

            (f) REMEDIES CUMULATIVE. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any such
right, power or remedy by any party shall not preclude the simultaneous or later
exercise of any other such right, power or remedy by such party.

            (g) NO WAIVER. The failure of any party hereto to exercise any
right, power or remedy provided under this Agreement or otherwise available in
respect hereof at law or in equity, or to insist upon compliance by any other
party hereto with its obligations hereunder, and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such

June 15, 1999

The Board of Directors
Texas Central Bancshares, Inc.
401 West Texas, Suite 100
Texas Central, Texas  79701-4414
Attention:  Michael Ruff

Members of the Board:

      We understand that Texas Central Bancshares, Inc. ("TCBI"), Bank United
Corp., a Delaware corporation ("BUC"), and BUC Acquisition Corporation II, a
Texas corporation ("Acquisition Company") have entered into an Agreement and
Plan of Reorganization (the "Merger Agreement") dated March 23, 1999, which
provides for the merger (the "Merger") of TCBI and its subsidiary, Texas Central
Bank National Association ("Texas Central" or the "Bank"), with and into a new
wholly owned Texas subsidiary corporation of BUC (the Acquisition Company).
Pursuant to the terms of the Merger Agreement, each issued and outstanding share
of common stock, par value $1.00, of TCBI, as of the date the Merger becomes
effective, will be converted into the right to receive 2.02797 (the "Exchange
Ratio") shares of Bank United Corp. Class A Common Stock, par value $0.01, not
to exceed in the aggregate 710,000 shares, as described in the Merger Agreement,
with certain provisions for fractional shares. The terms and conditions of the
Merger are more fully set forth in the Merger Agreement. We understand that as a
result of the Merger, (i) TCBI and the Acquisition Company shall each be merged
with and into BUC and each will cease to exist and that (ii) Texas Central will
be merged with and into Bank United Corp. and will cease its separate existence.

      You have asked for our opinion as to whether the Exchange Ratio pursuant
to the Merger Agreement is fair, from a financial point of view, to holders of
the TCBI common stock.

      Our opinion is based on information furnished to us by TCBI and BUC, their
attorneys, accountants, or obtained by us from published and verbal sources we
consider relevant. We have relied upon and assumed the accuracy and completeness
of all information submitted to us or that as publicly available and have made
no independent verification of this information. We have not conducted any
valuation or appraisal of any assets or liabilities, nor have any such
valuations or appraisals been provided to us. In relying upon financial analyses
and forecasts provided to us, we have assumed that they have been reasonably
prepared based on assumptions reflecting the best currently available estimates
and judgments by management of TCBI and BUC as to the expected future results of
operations and financial condition of TCBI and BUC to which such analyses or
forecasts relate. We have relied as to all legal matters relevant to rendering
our opinion upon the
<PAGE>
advice of counsel. TCBI and BUC's management have informed us that they know of
no additional information which would have a material effect upon our valuation.

      In arriving at our opinion, we have followed generally accepted industry
practices for the valuation of commercial banks and have used such valuation
methodologies as we have deemed necessary or appropriate for the purposes of
this opinion. In giving our opinion, we have given consideration to all
available financial data and other relevant factors effecting fair market value
including, but not limited to the following, (i) reviewed certain publicly
available financial statements and other information of TCBI and BUC, (ii)
reviewed certain internal financial statements and other financial and operating
data concerning TCBI and BUC prepared by the management of TCBI and BUC, (iii)
analyzed certain summary financial projections concerning TCBI and BUC prepared
by the management of TCBI and BUC, respectively; (iv) reviewed and discussed
with senior executives of TCBI the past and current operations and prospects of
TCBI, (v) reviewed and discussed with senior executives of BUC the past and
current operations and financial condition and the prospects of BUC and analyzed
the estimated pro forma impact of the Merger, including on the combined
company's earnings per share, consolidated capitalization and financial ratios,
(vi) reviewed and discussed with senior executives of TCBI and BUC the strategic
objectives of the Merger and the long term benefits expected to result from the
Merger, including without limitation, certain estimates and timing of synergies
and other cost savings for the continued company, (vii) reviewed reported prices
and trading activity for transactions in TCBI stock and BUC stock, (viii)
compared the financial performance of TCBI and BUC and the prices and trading
activity of TCBI and BUC with that of certain other comparable publicly traded
companies and their securities, (ix) reviewed the financial terms, to the extent
publicly available, of certain comparable transactions, (x) reviewed the Merger
Agreement and certain related documents, and (xi) considered other such factors
as we have deemed appropriate.

      Neither SAMCO Capital Markets ("SAMCO") nor the individuals involved in
this valuation have any present or contemplated future financial interest in
TCBI or BUC which might prevent them from rendering a fair and unbiased opinion.
Our opinion is necessarily based upon the business, market, economic and other
conditions as they exist on, and can be evaluated as of, the date of this
letter, and does not address TCBI's underlying business decision to enter into
the Merger Agreement or constitute any recommendations to any holder of common
stock of TCBI as to how such holder should vote with respect to the Merger
Agreement. We were requested to, and did, solicit third party offers to acquire
all or any part of TCBI. In addition, we understand that the Merger may render
in effect a taxable transaction and our opinion may be used for purposes of the
shareholders in determining the tax liability they may have upon conversion.

      In reaching our opinion, we have assumed that the Merger will be
consummated in accordance with the terms described in the Merger Agreement. We
consent to the reference to our firm and the inclusion of our opinion in its
entirety in any filing with the Securities and Exchange Commission related to
the Merger. Based on the foregoing and in consideration of all relevant factors,
it is our opinion, as of the date of this letter, that the Exchange Ratio is
fair and equitable to all holders of Texas Central Bancshares, Inc. common
stock, from a financial point of view.
