                      AGREEMENT AND PLAN OF REORGANIZATION



     This Agreement and Plan of Reorganization (hereinafter called the
"Agreement") dated as of January 9, 1996, is executed by and between Texas State
Bank, McAllen, Texas, a Texas banking association ("Texas State Bank") and First
State Bank and Trust Company, Mission, Texas, a Texas banking association
("First State Bank").  Texas State Bank is a wholly owned subsidiary of Texas
Regional Bancshares, Inc., a Texas corporation ("Texas Regional"), and Texas
Regional joins into the execution hereof for the purposes herein expressed.

     Subject to the fulfillment of the terms and conditions of this Agreement,
the undersigned shareholders of First State Bank (sometimes individually called
a "Shareholder" or collectively the "Shareholders") join into the execution
hereof for the purposes set forth in section 9.11 herein.


                              W I T N E S S E T H:

     This Agreement provides for the merger of First State Bank with and into
Texas State Bank, pursuant to the terms of this Agreement and Plan of
Reorganization.  As a result of the merger, the shareholders of First State
Bank, will receive an aggregate of $79,000,000.00 in cash (subject to adjustment
and calculated and payable as herein provided).  The aggregate consideration
shall be exchanged by Texas State Bank for all of the outstanding shares of
First State Bank capital stock, and, upon the closing of the transaction, First
State Bank will be merged with and into Texas State Bank and First State Bank
will cease its separate existence.

     As a result of the merger transaction, all rights, privileges, immunities,
powers and franchises of each of Texas State Bank and First State Bank shall be
merged into Texas State Bank as the surviving banking association.  Without any
other action, at the Effective Time, Texas State Bank shall be vested with all
property, real, personal and mixed, of the merging associations and shall
thereafter possess all of the interests, both public and private, of each of the
merging associations, and all claims of creditors of each of First State Bank
and Texas State Bank shall survive and any liens shall be preserved unimpaired
in Texas State Bank as the surviving association.  All of the foregoing shall be
effected pursuant to and as set forth in this Agreement and in an Agreement of
Merger (the "Merger Agreement") to be executed by and among the Corporation,
First State Bank and Texas State Bank, the form of which is attached hereto as
SCHEDULE 1.1.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements herein contained, the parties hereto agree as follows:

<PAGE>

                                    ARTICLE 1

                                 PLAN OF MERGER


     A.   THE MERGER.  Upon and subject to the terms and provisions hereof, at
the Effective Time, as hereafter defined, First State Bank shall be merged with
and into Texas State Bank (the "Merger"), with the effect that the separate
existence of First State Bank shall cease.  Texas State Bank and First State
Bank, shall each execute and deliver the Merger Agreement in the form attached
hereto as SCHEDULE 1.1 (the "Merger Agreement") as soon as reasonably
practicable following the execution and delivery hereof.  The Merger Agreement
shall provide for the conversion, on the Effective Date (as hereinafter
defined), of all of the outstanding shares of First State Bank capital stock
into the right to receive the Total Consideration, as hereafter defined.  At the
Effective Time of the Merger, the rights of the shareholders of First State Bank
shall, without the requirement of further action on the part of the
shareholders, immediately be converted into the right to receive cash
consideration, as herein provided, for each share of First State Bank held by
such shareholder of record as of the Effective Time and such shareholder shall
cease to be a shareholder of First State Bank and such share certificate shall
for all purposes be deemed only to represent a right to receive cash pursuant to
this Agreement and the Merger Agreement.

     B.   CONSIDERATION.  Upon consummation of the merger, each share of First
State Bank outstanding shall be converted into the right to receive cash
consideration as herein provided.  The consideration to be paid by Texas State
Bank shall be $395 per share (the "Per Share Consideration") which consideration
shall be exchanged for each of the 200,000 outstanding shares of First State
Bank, for an aggregate consideration of $79,000,000.00 (the "Total
Consideration"), adjusted as herein provided for amounts attributable to
shareholders exercising dissenters' rights of appraisal.

          1.   An amount equal to the Per Share Consideration (adjusted as
     herein provided for amounts attributable to shareholders exercising
     dissenters' rights of appraisal) shall be paid by Texas State Bank to
     each First State Bank shareholder who has not exercised his, her or
     its dissenters' rights of appraisal upon surrender of such
     shareholder's share certificate or certificates evidencing shares of
     First State Bank stock.  Such amount shall be payable at the time of
     Closing to shareholders who have surrendered such share certificates
     at or prior to the date of Closing, by check made payable to each
     shareholder and mailed to such shareholder at the shareholder's
     address as stated on the stock transfer records of First State Bank,
     or (if an account is designated by such shareholder not less than
     twenty days prior to the date of Closing) by direct deposit or wire
     transfer into such account on the date of Closing.  Amounts payable to
     shareholders who surrender their share certificates following the date
     of Closing shall be paid within ten days following receipt of the
     shareholder's share certificate.  The stock transfer records of First
     State Bank shall for all purposes be closed as of the Effective Time,
     and no transfer of record of any of the shares of First State Bank
     capital stock shall take place thereafter.

          2.   Any amounts that would otherwise have been payable pursuant
     to section 1.2.1 or 1.2.2 to any shareholder of First State Bank who
     has exercised his, her or its dissenters' rights of appraisal pursuant
     to applicable provisions of

<PAGE>

     law shall be retained by Texas State Bank until such shareholder
     relinquishes his, her or its right of dissent, at which time the provisions
     of section 1.2.1 and 1.2.2 shall apply, except that the date of payment for
     such shares shall be extended to not less than ten days following the date
     of relinquishment of such dissenters' rights.  In the event that a
     shareholder of First State Bank exercises his, her or its dissenters'
     rights, if such shareholder receives as consideration for his or her shares
     an amount per share in excess of the Per Share Consideration, the amount
     payable to other shareholders in consideration of the merger shall be
     adjusted as follows:  the Total Consideration shall be reduced by the full
     amount payable to the dissenting shareholder and such adjusted Total
     Consideration shall be divided by the number of shares held by shareholders
     not exercising dissenters' rights to determine the amount of Per Share
     Consideration to be paid to all such other shareholders.

          3.   Any amounts payable to shareholders who surrender their
     share certificates after the date of Closing shall not bear interest
     attributable to periods either before or after the date of Closing.

     C.   CLOSING.  The closing ("Closing") of the transactions contemplated by
this Agreement shall be effected on the latest of the following dates, or as
promptly thereafter as reasonably practicable (the "Closing Date"):

          1.   March 31, 1996;

          2.   The thirtieth calendar day after the date of approval by the
     Federal Reserve Board as required by Section 7.02 herein; or

          3.   Such date as may be prescribed by the Federal Reserve Board,
     the Texas Banking Department or by any other federal or state agency
     or authority pursuant to an applicable federal or state law, order,
     rule or regulation, prior to which consummation of the transactions
     provided herein may not be effected; or

          4.   If the transactions contemplated by this Agreement are being
     contested in any legal proceeding and Texas State Bank, pursuant to
     Section 7.02 hereof, has elected to contest the same, then the date
     that such legal proceeding has been brought to a conclusion favorable,
     in the judgment of Texas State Bank, to the consummation of the
     transactions contemplated hereby; or

          5.   Such other date as the parties may select by mutual
     agreement.

The Closing shall take place at the offices of Texas State Bank, Kerria Plaza,
Suite 301, 3700 N. Tenth Street, McAllen, Texas, on the Closing Date, or at such
other place as shall be mutually agreeable.  If such Closing shall not have been
accomplished on or before June 30, 1996, this Agreement, and the Merger
Agreement if executed and delivered prior thereto, shall, at the election of
either party hereto by written notice, terminate and be of no further force or
effect.  In addition, First State Bank may terminate this Agreement and the
Merger Agreement if Texas Regional fails to file a registration statement with
the Securities and Exchange Commission, pursuant to which Texas Regional
proposes to offer for sale shares of Texas Regional capital stock with an
estimated price that will yield an aggregate of $40,000,000.00 in proceeds to
Texas Regional, within forty-five days following the date of Texas Regional's
receipt

<PAGE>

of audited financial statements for both First State Bank and The Border Bank,
Hidalgo, Texas in each case accompanied by the unqualified report of KPMG Peat
Marwick, for fiscal years ended December 31, 1995, 1994 and 1993; PROVIDED THAT
First State Bank may exercise the right of termination in this sentence only if
such right is exercised by written notice to Texas State Bank within ten days
following expiration of such forty-five day period.  Any termination which
occurs through no fault of any of the parties to this Agreement or the Merger
Agreement shall be without liability to any of the parties hereto or to the
Merger Agreement, except for the obligation of Texas State Bank to make certain
payments required pursuant to section 5.7 hereof.  This Agreement and the Merger
Agreement may be terminated at any time prior to the Effective Date by the
mutual action of the respective Boards of Directors of First State Bank and
Texas State Bank.

     D.   EFFECTIVE DATE.  The parties hereto agree to take, on or prior to the
Closing Date, all such action, and to execute and deliver all such instruments
and documents, as may be necessary or advisable, on the advice of counsel, to
cause the Merger Agreement, subject to consummation of the Closing, to become
effective as soon as practicable after the Closing Date.  The merger shall
become effective at the time specified for consummation of the merger (herein
referred to as the "Effective Time") in the order to be issued by the Texas
Banking Department.

     E.   EFFECT OF MERGER.  As a result of the merger, First State Bank's
assets and business shall be acquired by Texas State Bank, free and clear of any
and all liens, claims or encumbrances.

                                    ARTICLE 2

               REPRESENTATIONS AND WARRANTIES OF FIRST STATE BANK


     First State Bank hereby represents and warrants to Texas State Bank as
follows:

     A.   ORGANIZATION OF FIRST STATE BANK.  First State Bank is a Texas state
banking association, duly organized and existing under the laws of the state of
Texas, and has full power and authority (including all licenses, franchises,
permits and other governmental authorizations which are legally required) to own
its properties and to engage in the business and activities now conducted by it,
including both its commercial banking business and its trust business.  First
State Bank has branch licenses and all other authority necessary to own and
operate branch bank facilities operated by First State Bank.  A list of the
branches presently operated by First State Bank, together with a list of
licenses pending for operation of additional branch facilities are included on
SCHEDULE 2.1.  True and complete copies of the Articles of Association and
Bylaws of First State Bank, as amended to date, have been delivered to Texas
State Bank, or (to the extent not previously delivered) First State Bank
covenants to deliver the same to Texas State Bank within 15 days following the
date hereof.  First State Bank (i) is duly authorized to conduct a general
banking business, in accordance with its charter, subject to the supervision of
the Texas Banking Department, the Federal Deposit Insurance Corporation and
other applicable regulatory authorities; (ii) is an insured bank as defined in
the Federal Deposit Insurance Act; and (iii) has full power and authority
(including all licenses, franchises, permits and other governmental
authorizations which are legally required) to engage in the business and
activities now conducted by it.  Except as disclosed in SCHEDULE 2.1, and except
for trust assets held in the ordinary course of business of acting as trustee
for third parties, First State Bank has no subsidiaries or affiliates, owns no
voting securities of any other corporation, and is not a

<PAGE>

member of any joint venture or partnership.  First State Bank is not a reporting
company under the Securities Exchange Act of 1934, as amended (the "1934 Act").

     B.   CAPITALIZATION AND OWNERSHIP.  The authorized capital stock of First
State Bank consists of 200,000 shares (the "Shares") of capital stock, par value
$20.00 per share, all of which are duly authorized, validly issued and
outstanding, fully paid, nonassessable, and are owned beneficially and of record
by the persons named in the shareholder list previously delivered by First State
Bank to Texas State Bank.  The Shares have not been issued in violation of the
preemptive rights of any stockholder.  There are no outstanding options,
warrants, conversion rights, calls or commitments of any kind obligating First
State Bank to issue, directly or indirectly, additional shares of its capital
stock, and no authorization therefor has been given.  First State Bank does not
have any outstanding commitment or obligation to repurchase, reacquire or redeem
any of its outstanding capital stock.  The undersigned common shareholders of
First State Bank have joined into the execution hereof to evidence their consent
to and written approval of the transaction on the conditions herein described,
and to evidence their agreement to vote for and support the approval of the
transaction (on the conditions herein described) at the special shareholders'
meeting to be called to consider the merger.  The undersigned own beneficially
and of record not less than 75% of the outstanding common stock of First State
Bank, and the holders of common stock of First State Bank are the only
shareholders who have the right to vote on the proposed merger of First State
Bank with and into Texas State Bank.

     C.   FINANCIAL STATEMENTS AND RECORDS.

          1.   First State Bank has delivered to Texas State Bank (i) the
audited balance sheet of First State Bank as of December 31, 1994 (the "December
31, 1994 Balance Sheet"), and the related audited statements of income, changes
in stockholders' equity and changes in financial position for the year then
ended, together with the notes thereto, accompanied by the report thereon of the
independent certified public accountant who examined such statements; and (ii)
the unaudited regulatory reports of condition of First State Bank as of December
31, 1993, 1992 and 1991, and the related unaudited statements of income and
changes in equity capital for each of the years then ended.  Except to the
extent qualified by the report of the independent accountant thereon, these
financial statements fairly present the financial position of First State Bank
as of the dates thereof and the results of its operations for the periods
indicated.  The December 31, 1994 Balance Sheet and audited financial statements
for the fiscal year then ended, have been prepared in conformity with generally
accepted accounting principles applied on a consistent basis.  To the best
knowledge of First State Bank, audits of First State Bank have been conducted in
accordance with generally accepted auditing standards.  In addition, First State
Bank has delivered to Texas State Bank its unaudited balance sheet and
regulatory report of condition as of September 30, 1995 (collectively, the
"September 30, 1995 Balance Sheet") and the related unaudited statements of
income, changes in stockholders' equity and changes in financial position for
the twelve-month period then ended.  In the opinion of the management of First
State Bank, these financial statements also fairly present the financial
position of First State Bank as of the date thereof and the results of its
operations for the period indicated and the financial records upon which such
financial statements are based have been kept in accordance with prudent banking
practices and the past practices of First State Bank.  Except as disclosed in
SCHEDULE 2.3.1, the September 30, 1995 Balance Sheet and related financial
statements for the nine-month period then ended, have been prepared in
accordance with generally accepted accounting principles, consistently applied.
The December 31, 1994 Balance Sheet and the September 30, 1995 Balance Sheet,
and the financial statements for the twelve and nine-month periods then ended,
described above are collectively referred to hereinafter as the "First State

<PAGE>

Bank Financial Statements."  Except as set forth in SCHEDULE 2.3.1, the First
State Bank Financial Statements do not, as of the dates thereof, include any
material assets or omit to state any material liability, absolute or contingent,
the inclusion or omission of which renders such financial statements, in light
of the circumstances under which they were made, materially misleading.  Without
limiting the generality of the foregoing, First State Bank specifically
represents to Texas State Bank that, except as set forth in SCHEDULE 2.3.1,
First State Bank has no liabilities, either accrued, contingent or otherwise,
which, individually or in the aggregate, are material, which have not been
reflected in the First State Bank financial statements (including the September
30, 1995 Balance Sheet) or which have been incurred in the ordinary course of
business since the date of the September 30, 1995 Balance Sheet.

          2.   Except as set forth in SCHEDULE 2.3.2, since December 31, 1994,
there have not been any material changes in the financial condition, results of
operations, business or prospects of First State Bank, other than changes in the
ordinary course of business, none of which individually or in the aggregate has
been materially adverse, nor have there been any other events or conditions of
any character which have individually or in the aggregate materially and
adversely affected the financial condition, results of operations, business or
prospects of First State Bank.

          3.   The books and records of First State Bank reflect the
transactions to which it is or was a party or by which its properties are or
were bound, and, to the extent applicable, such books and records are and have
been properly kept and maintained in accordance with the law and prudent banking
principles except as otherwise disclosed in SCHEDULE 2.3.3.  As of the date
hereof and as of the Closing, all of the minute books of First State Bank are
and will be complete, accurate and current in all material respects.

          4.   Total trust assets under management by First State Bank as of
September 30, 1995, are as set forth in the September 30, 1995 Balance Sheet.
All books and records related to the trust business of First State Bank are
true, correct and complete, and all such trust business is operated in full
compliance with sound banking practices, applicable fiduciary requirements and
applicable provisions of law, including applicable provisions of the Texas
Banking Act and applicable provisions of the Texas Probate Code.  Except as set
forth in SCHEDULE 2.3.4, during the three years prior to the date hereof, First
State Bank has not experienced any material change, whether or not deemed
adverse, in the operation of its trust business.

     D.   LOANS.

          1.   All Loans included in the assets of First State Bank, and all
commitments to make Loans by First State Bank (including leasing transactions
and off balance sheet lending transactions such as letters of credit), have been
made in the ordinary course of business of First State Bank and do not present
more than the normal risk of uncollectibility or other unfavorable features,
except as disclosed in Schedule 2.4.1.

          2.   All Loans to directors, officers and beneficial owners of 5% or
more of the outstanding capital stock of First State Bank, and loans to any
person or company related to or affiliated with any such person, are listed on
Schedule 2.4.2.  The Loans listed on Schedule 2.4.2 do not present more than the
normal risk of uncollectibility or other unfavorable features.

          3.   First State Bank's reserves for loan losses have been calculated
in

<PAGE>

accordance with all applicable rules and regulations.  In the reasonable opinion
of the management, officers and directors of First State Bank, the reserve for
loan losses shown on the September 30, 1995 Balance Sheet is adequate in all
respects to provide for all losses on loans outstanding as of the date of
September 30, 1995 Balance Sheet.

     E.   PROPERTIES.  First State Bank has good and indefeasible title to all
assets and properties, whether real or personal, tangible or intangible, which
it purports to own, including without limitation, all assets and properties
reflected on the September 30, 1995 Balance Sheet or acquired subsequent thereto
(except to the extent such assets and properties have been disposed of for fair
value in the ordinary course of business since the date of the September 30,
1995 Balance Sheet), subject to no liens, mortgages, security interests,
encumbrances, easements, title imperfections, or charges of any kind except (i)
as noted in the September 30, 1995 Balance Sheet or the notes to the First State
Bank Financial Statements, (ii) statutory liens not yet delinquent, (iii)

          1.   First State Bank hereby agrees to indemnify, defend and hold
harmless Texas State Bank and Texas Regional, and their respective officers,

severally, to indemnify, defend and hold harmless First State Bank and its
officers, directors, employees, agents and attorneys from and against any and
all losses, claims, damages, expenses or liabilities to which First State Bank
may become subject (including any arising as a result of the consummation of the
transaction described in this Agreement and any arising under the Securities Act
of 1933 or the Securities Exchange Act of 1934, or any rule, order or regulation
pursuant thereto), arising out of or based upon (i) breach of a representation,
warranty, covenant or agreement of Texas State Bank in this Agreement or in the
performance hereof; and (ii) any misleading or untrue statement of a material
fact by or on behalf of Texas State Bank, or any omission of a material fact

under which they were not misleading, including any such statement as is made in
the context of the sale by Texas Regional of common stock, the proceeds of which
are in part expected to be used to fund the payment of the Total Consideration

          3.   Each of Texas State Bank and First State Bank (to the extent of
an indemnification obligation hereunder, herein referred to as the "Indemnifying
Party") will indemnify the other parties hereto and each of such other party's
directors, officers and each person who "controls" such other party within the
meaning of such term as used in Section 15 of the 1933 Act (such persons being
herein called the "Indemnified Parties") and will defend and hold the
Indemnified Parties harmless from and against any and all losses, claims,
damages, expenses, or liabilities to which the Indemnified Parties may become
subject under the common


<PAGE>

law or otherwise insofar as:

               a.   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 communications to
     shareholders, or any application or statement filed pursuant to this
     Agreement or arising out of or based upon the omission or alleged
     omission to state therein a material fact necessary in order to make
     the statement therein, in the light of the circumstances in which they
     were made, not misleading, but only insofar as any such statement or
     omission was made in reliance upon and in conformity with information
     furnished by the party against whom indemnification is sought
     hereunder for use therein; and

               b.   such losses, claims, damages, expenses, or liabilities
     are incurred by the Indemnified Parties (or are losses, claims,
     damages, expenses or liabilities with respect to which the Indemnified
     Parties become subject), under the common law or otherwise, arising
     out of or in any way attributable to the breach of any warranty or
     representation made by such party herein or pursuant to the terms
     hereof, or the failure of such party to perform any covenant or
     obligation contained in this Agreement.

          4.   The indemnification obligations contained herein shall expressly
include the obligation of the Indemnifying Party to reimburse the Indemnified
Party for any legal or other expenses (including counsel fees) reasonably
incurred by them in connection with investigating or defending against any and
all such losses, claims, damages, expenses, liabilities or actions whether or
not resulting in any liability.

          5.   The Indemnified Parties shall, within twenty (20) days after the
receipt by them of any notice of any claim or of the commencement of any
litigation in respect of which indemnity may be sought hereunder, notify the
Indemnifying Party thereof.  The omission to notify the Indemnifying Party of
any such claim or litigation shall relieve the Indemnifying Party from any
liability which it may have under the indemnity agreement contained herein, but
shall not relieve the Indemnifying Party from any other liability which it may
have to the Indemnified Parties, other than that raised in any such claim or
litigation explicitly or by reasonable implication or that which may estop the
Indemnifying Party from raising and effecting some defense it might otherwise
have raised had such notice been properly given.  If any such litigation shall
be brought against the Indemnified Parties and if the Indemnified Parties shall
notify the Indemnifying Party of the commencement thereof, the Indemnifying
Party shall be entitled, unless in the opinion of counsel to the Indemnified
Party there exist issues as to which the interests of the Indemnified and
Indemnifying Parties are adverse, to participate in (and, to the extent that it
shall wish, to direct) the defense thereof at its own expense, but such defense

stockholders' equity and changes in financial position for the year then ended,
together with the notes thereto, to be prepared in accordance with generally
accepted accounting principles and examined by a firm of independent certified
public accountants reasonably acceptable to Texas State Bank and Texas Regional
and (ii) to deliver such financial statements (together with the unqualified
opinion of the auditors with respect thereto and accompanied by such
accountant's consent to use of such financial statements in the registrations
statement herein described) to Texas State Bank and Texas Regional.  First State
Bank hereby agrees that, upon delivery to Texas State Bank, the First State
Information shall not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading.

          2.   Texas State Bank agrees to provide any and all information as may
be reasonably required by First State Bank for purposes of communications with
shareholders of First State Bank pending the Closing and for purposes of the
proxy statement related to obtaining

<PAGE>

the approval by First State Bank shareholders of the transaction herein
described (collectively, the "Texas State Information").  Texas State Bank
hereby agrees that, upon delivery to First State Bank, the Texas State
Information shall not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading.

     D.   ACCESS.  From and after the date of this Agreement, First State Bank
shall afford to the officers, attorneys, accountants and other authorized
representatives of Texas State Bank full and free access to the properties,
books, contracts, commitments and records of First State Bank at all reasonable
times during business hours, and such representatives of Texas State Bank shall
be furnished with true and complete copies of the same and with all other
information concerning the affairs of First State Bank as such representatives
may reasonably request.  Any such information treated as confidential by First
State Bank shall be kept confidential by the representatives of Texas State Bank
(and shall be used by them only in connection with this Agreement and the
transactions contemplated hereby) except to the extent that (i) it was already
known to such representatives when received, (ii) it hereafter becomes lawfully
obtainable from other sources, or (iii) it is disclosed by Texas State Bank in
any document filed with the Securities and Exchange Commission, the Federal
Reserve Board or any other governmental agency or authority.  In the event the
transactions contemplated by this Agreement and the Merger Agreement are not
consummated, Texas State Bank agrees to return to First State Bank any
confidential information delivered by First State Bank to Texas State Bank
pursuant to this Section.

     E.   ENVIRONMENTAL INSPECTION.  First State Bank expressly agrees to supply
Texas State Bank with historical and operational information regarding the real
properties owned or operated by, or used in connection with the operation of the
business of, First State Bank, and any premises heretofore used in connection
with the operation of the business of First State Bank, and any other properties
included in the Real Property, including (but not limited to) any environmental
tests or surveys made of such properties.  First State Bank agrees to cooperate
with any reasonable request of Texas State Bank related to site assessment or
site review related to any environmental matter or investigation, including the
making available of such personnel of First State Bank as Texas State Bank may
reasonably request.  At Texas State Bank's discretion, Texas State Bank may
arrange for one or more independent contractors to conduct tests of the Real
Property and any other premises now or heretofore used in connection with the
business of First State Bank in order to identify any presence of, or present or
past release or threatened release of, any waste materials or any chemical
substances, including, without limitation, any Environmental Hazards.  Any such
test may be done at any time, or from time to time, upon reasonable notice and
under reasonable conditions, which do not impede the performance of the tests.
Such tests may include both above and below ground testing for environmental
damages or the presence of Environmental Hazards or Hazardous Material
Contamination or such other tests as Texas State Bank may deem reasonably
necessary.  Any and all costs of third parties associated with obtaining such
information shall be borne equally by Texas State Bank and First State Bank.  In
the event such tests indicate the presence of Hazardous Material Contamination,
the parties shall endeavor to obtain a reasonably reliable estimate of the cost
of remediating or removing such Hazardous Material Contamination prior to the
Closing.  In the event that such estimated cost is less than $25,000, First
State Bank shall accrue the cost thereof as an expense prior to Closing for
purposes of calculating the minimum net worth required at Closing, in which
event the parties shall proceed to Closing on the terms and conditions described
in this Agreement.  In the event that such estimated cost exceeds an aggregate
of $25,000, Texas State Bank may elect to either (i) proceed with the
transaction on

<PAGE>

the terms and conditions herein provided, without modification, in which event
the parties shall perform their respective obligations as herein provided,
without modification; or (ii) proceed with the Closing on the terms and
conditions herein provided, on the further condition that First State Bank
either fully remediate and remove the Hazardous Material Contamination prior to
Closing or (at Texas State Bank's option) accrue the full cost thereof as an
expense prior to Closing for purpose of calculating the minimum net worth
required at Closing, and in either of such events First State Bank shall be
entitled to acquiesce in such remediation and removal (or if Texas State Bank
has so elected, the accrual of the cost thereof), or First State Bank shall be
entitled to unilaterally terminate this Agreement.  In the event that the cost
of remediation exceeds $25,000, or if the parties are unable to obtain a
reasonably reliable estimate of the remediation and removal cost prior to
Closing, Texas State Bank shall be entitled to exercise the options set forth in
the preceding sentence, or to terminate this Agreement without further
liability.

without the prior written consent of Texas State Bank, First State Bank (i) will
not permit any change to be made in its charter or Bylaws; (ii) will not take

                                   Section 5.

     At the Effective Time, the corporate existence of First State Bank and

     beneficially and of record immediately prior to the Effective Time by

     record.  The outstanding certificates representing such shares of
     First State Bank common stock as held by such shareholders, to the

     delivery of his or her First State Bank share certificates to the

     State Bank common stock immediately prior to the Effective Time, and
     all such shares shall be owned and held by the Company.  The existing
     shares of First State Bank shall be cancelled.

          (d)  The capital of First State Bank and Texas State Bank
     immediately prior to the merger shall be combined as the capital of
     the Surviving Bank, subject to such adjustment as may be necessary to
     properly account for the transaction as a purchase for financial
     accounting purposes.

          (e)  All rights of the holders of outstanding certificates of
     First State Bank common stock under the plan of merger described in
     this Agreement shall be determined from the stock transfer records of
     First State Bank as of the close of business on the date specified in
     the approval letter to be issued by the Federal Reserve Board, or the
     Texas Department of Banking, or other applicable regulatory authority,

the Board of Directors of Texas State Bank as they exist immediately before the
Effective Time.


                                   Section 9.

     Effective as of the Effective Time and until amended by an appropriate
action taken by or on behalf of the Surviving Bank, the Articles of Association
of the Surviving Bank shall be the Articles of Association of Texas State bank
as in effect as of the Effective Time.  The Bylaws of the Surviving Bank shall

                                   Section 10.

     This Agreement may be terminated by the mutual action of the Boards of
Directors of each party hereto.  Since time is of the essence of this Agreement,

                          FINANCIAL STATEMENTS, RECORDS


                                 SCHEDULE 2.3.1


     1.   The unaudited call reports for the periods ending December 31, 1993,
1992 and 1991 and September 30, 1995 do not contain the footnote disclosures
required by generally accepted accounting principals.

     2.   The audited financial statements for the period ending December 31,
1994 included a liability for "deferred compensation payable" in the amount of
$506,389.  This was an adjusting entry required by the Bank's auditors in
connection with the audit of the Bank's December 31, 1994 financials.  This
adjusting entry was not carried over to the Bank's general ledger and is
therefore not shown as a liability on the Bank's unaudited September 30, 1995
call report.

     3.   The First State Bank Financial Statements and the September 30, 1995
Balance Sheet do not disclose liabilities for loan commitments, letters of
credit, unasserted claims or for pending or overtly threatened litigation.

     4.   In the past, the Bank has elected not to amortize loan costs over the
life of the loan as contemplated by FASB 91; therefore, the unaudited reports of
regulatory condition for the periods ending December 31, 1993, 1992, and 1991
and September 30, 1995, as well as the audited financial statements for the
period ending December 31, 1994, do not show deferred loan costs.

     5.   The Bank does not book on a current month end basis changes in fair
market value on "available for sale securities" as contemplated by FASB 115.
These adjustments have typically been made only on a quarterly basis, although
such adjustments are reflected on the Bank's general ledger for the period
ending November 30, 1995.  The FASB 115 adjustment is reflected on each
quarterly regulatory report of condition filed by the Bank.

     6.   See Schedule 2.8 for description of treatment by Bank of accruals for
deferred taxes.

     7.   The Bank records interest income on loans "greater than or equal to 90
days past due and still accruing" on the general ledger; however, in order to
comply with regulatory reporting requirements, this income is reversed quarterly
and not reported on the Bank's regulatory reports of conditions.

     1.   See Schedule 2.3.1 above and Schedules 2.13 and 2.16.

                                 SCHEDULE 2.4.1


     1.   See Schedule 2.16 and examination reports with regard to certain
criticized lending practices and for a summary of specifically criticized loans
and related matters disclosed in examination reports and correspondence with
regulatory authorities.


     2.   The Bank has previously furnished Texas State Bank with copies of its
(i) loan watch list as of January 4, 1996; (ii) list of loans on non-accrual as
of December 31, 1995; and (iii) past due loan report as of December 31, 1995
(collectively the "Loan Reports").  Each of the loans described in the Loan
Reports and each loan specifically criticized in the examination reports
described in Section 2.16, presents more than the normal risk of
uncollectibility or other unfavorable features.


                                 SCHEDULE 2.4.2

     1.   The Bank has previously furnished Texas State Bank with a listing of

     3.   LARRY HOFLAND AND MARSHA HOFLAND V. FIRST STATE BANK & TRUST COMPANY
          OF MISSION, Cause No. C-6591-95-D, in the 206th Judicial District
          Court, Hidalgo County, Texas.  This is a cause of action against the
          Bank for fraud, breach of contract, intentional infliction of
          emotional distress and negligence arising out of the foreclosure and
          subsequent sale of various properties of the Plaintiffs' on which the
          Bank had obtained lien positions in order to secure loans made to the
          Plaintiffs.  The suit was only recently filed and even more recently
          served on the Bank.  The Bank has referred the matter to its counsel.
          An answer has not yet been

<PAGE>

          filed.

     4.   Except as set forth in Schedule 2.16 and the examination reports
          furnished to Texas State Bank under Section 2.16 of the Agreement,
          Border Bank knows of no violations of the kind described in the fourth
          sentence of Section 2.7 of the Agreement.

                                  SCHEDULE 2.8

                                      TAXES


     1.   The Bank is not under examination, nor has it been notified of any
examination or any proposed examination by any taxing authority.

     2.   The Bank computes appropriate reserves for deferred taxes only on a
quarterly basis; therefore, the statements referred to in Section 2.8 for the
period ended October 31, 1995 and the Bank's general ledger would not reflect
accruals for deferred taxes.

<PAGE>

                                  SCHEDULE 2.9

                                    CONTRACTS


    (i)   EMPLOYMENT CONTRACTS.  The Bank does not have written employment
          contracts with any employees.  The Bank has previously furnished Texas
          State Bank with a list of current employees together with their
          salaries.  In addition to their respective salaries, the Bank has had
          a policy for many years of paying a bonus in an amount equal to 10% of
          each employee's salary.  This bonus is accrued on the books of the
          Bank and paid on December 15 of each year.  The Bank also participates
          in a cafeteria plan for the benefit of its employees.  This plan
          allows employees to set aside funds for medical expenses on a tax free
          basis.  The plan is a "control group" plan that also includes
          employees of an affiliate, The Border Bank, Hidalgo, Texas and
          Citizens State Bank, Roma, Texas.  The cafeteria plan covers life,
          accidental death and dismemberment, medical and dental.  A policy
          maintained through Jefferson Pilot Insurance Company covers certain
          employee life, accidental death, dismemberment, and health claims.
          The Bank pays 100% of the premiums for officers and their dependents.
          The Bank pays one-half of the premiums for other employees and their
          dependents.  There is an additional disability policy covering
          officers, E. Brent Bottom and Yvonne Trevino.  The premiums for this
          policy ($1500/each) are paid by the Bank.  Officers of the Bank are
          reimbursed for personal automobile usage and certain officers are
          allowed to use Bank credit cards for expenses related to the business
          of the Bank.  The Bank also pays club membership fees, dues and
          expenses for Elliott Bottom (Cimarron Country Club and McAllen Country
          Club), Brent Bottom (Cimarron Country Club, McAllen Country Club and
          The Tower Club) and for Bryan Calcote (Cimarron Country Club).
          Certain athletic club dues and related expenses are also paid on
          behalf of certain officers.  Elliott Bottom is also furnished with
          three Bank owned vehicles for his use.  Employees with over 15 years
          employment are afforded a three week paid vacation.  Other employees
          are afforded a two week paid vacation.

   (ii)   OTHER EMPLOYEE BENEFITS.  The Bank has three separate deferred
          compensation plans for the benefit of certain Bank employees.  The
          plans provide for retirement benefits to be paid to the specific
          employee or a designated beneficiary or estate if death occurs prior
          to payment of the full amount of deferred compensation on

<PAGE>

          reaching age 65.  One plan entered into on December 10, 1963,
          commenced payments to a retired employee of approximately $13,000 per
          year on January 4, 1988, continuing annually thereafter through June
          2003.  A second plan, entered into on September 1, 1979, provides for
          payments of approximately $13,300 per year which was scheduled to
          commence on April 1, 1990, continuing annually thereafter through June
          2005; however, the employee elected to receive an amount less than
          that provided for in the plan over a longer period of time.  The third
          plan, covering Chairman Elliott Bottom, provides for a retirement
          benefit payment of $50,000 per year commencing in March, 1999 and
          continuing annually thereafter for 20 years.  The Bank owns and is the
          beneficiary of four life insurance policies on the three employees
          covered by the deferred compensation plans.  The life insurance policy
          face values are in amounts approximately equal to the total benefits
          paid under the plans.  The Bank owns two policies on the life of
          retired employee L. Jane Bell and one each on the lives of E. Downey
          Davis and Elliott Bottom.

  (iii)   MATERIAL LEASES OR LICENSES.

          None


   (iv)   CONTRACTS OR COMMITMENTS FOR CAPITAL EXPENDITURES IN EXCESS OF
          $100,000.

          a)   EDS CONTRACT. - On September 13, 1994, the Bank and Electronic
               Data Systems Corporation ("EDS") entered into that certain
               Agreement for Information Technology Services (the "EDS
               Agreement").  The EDS Agreement provides for EDS to render
               various specified data processing services to the Bank for a
               fixed monthly rate of $18,563 per month for designated "basic"
               services plus additional charges for certain "optional" services
               that the Bank may call upon EDS to perform.  The initial term of
               the EDS Agreement is for a period of five years from September
               13, 1994.  Under Section 7.2 of the EDS Agreement, if 50% or more
               of the stock or assets of the Bank change hands, the EDS
               Agreement may be terminated "upon the consummation of such
               acquisition or on a mutually agreeable date thereafter."
               However, in the event

<PAGE>

               of such termination, EDS is entitled  to receive liquidated
               damages, as described in Section 7.6.  Under Section 7.6, EDS is
               entitled to receive the SUM of (a) all actual disengagement costs
               and expenses reasonably incurred by EDS in connection with
               termination PLUS a 25% "management fee" on such costs; AND (b) an
               amount equal to 80% of the total compensation "which would have
               been paid to EDS" under this the EDS Agreement during the
               remainder of its term.  (The EDS Agreement provides that EDS'
               total expected compensation is to be determined by multiplying
               the number of months remaining in the initial term by the average
               monthly charge to the Bank for the 12 months preceding the month
               in which notice of termination was given.)  On September 13,
               1994, the Bank and EDS entered into a Addendum to the EDS
               Agreement ("the Addendum").  The Addendum provides that the
               liquidated damages provisions of Section 7.6 of the EDS Agreement
               DO NOT APPLY if:  (a) the Bank changes ownership prior to
               September 13, 1996; AND (b) the Bank gives EDS 180 days prior
               written notice of the termination.  In such event, EDS'
               liquidated damages under the EDS Agreement are limited to the
               actual expenses incurred by EDS as a part of the deconversion
               process.


    (v)   CONTRACTS OR OPTIONS TO BUY OR SELL PROPERTY OUTSIDE ORDINARY COURSE
          OF BUSINESS.

          None


   (vi)   LOAN COMMITMENTS OR CREDIT EXTENSIONS IN EXCESS OF $500,000.

          The Bank has previously furnished Texas State Bank with a
          copy of Loan Commitments and Credit Extensions in excess of
          $500,000.

                           ABSENCE OF CERTAIN CHANGES

     1.   LOSSES CAUSED BY BEYDA PRUNEDA PENA.  Mrs. Pena was an employee of the
Bank from 1991 to August 1995 when she was terminated for acts of embezzlement
involving both loans and deposits.  The Bank has documented to date
approximately $143,000 in such losses, $108,000 of which have already been
reimbursed to the Bank under its blanket bond insurance policy.  A further
$15,000 in claims are currently being processed by the insurance company.  Since
the Bank's embezzlement coverage carries a $25,000 deductible, it appears that
net losses to the Bank will be limited to approximately the amount of this
deductible.  Mrs. Pena pleaded guilty to criminal charges brought against her by
the U.S. Attorney in U.S. District Court.  Sentencing is scheduled for
January 11, 1996.  The extent of Ms. Pena's suspected criminal activity is more
fully described in that certain letter dated September 7, 1995 from Yvonne A.
Trevino, Vice President of the Bank, to Assistant U.S. Attorney Luis Martinez.
A copy of this letter and the FDIC incident report have been delivered to Texas
State Bank.  A further description of the status of the Bank's insurance claim
is contained in a letter dated December 21, 1995 from BancInsure, Inc. to Ms.
Trevino, a copy of which has also been furnished to Texas State Bank.

                       REGULATORY MATTERS AND EXAM REPORTS

     1.   The Board of Directors of the Bank and the Banking Commissioner of
Texas entered into a Memorandum of Understanding ("MOU") on December 14, 1993.
The MOU was issued as a result of specific criticisms and alleged deficiencies
reflected in the October 4, 1993, Report of Examination issued by the Texas
Department of Banking.  The MOU documents an agreement reached between the
Commissioner and the Board of Directors concerning ten management goals and
corrective actions with respect to the Bank and sets forth time frames within
which these goals and corrective actions were to be accomplished.  The Board of
Directors, individually and collectively, agreed to cause management of the Bank
to take corrective actions and to use its best efforts to accomplish the goals
which were set forth in the MOU.  In subsequent examination reports and in a
letter dated September 26, 1995, the Texas Department of Banking has criticized
the Board's compliance with certain provisions of the MOU.  In the letter dated
September 26, 1995, Randall S. James, Deputy Commissioner, advised the Board of
Directors that the Texas Department of Banking's examination of July 11, 1994,
found that the Bank and Board were in compliance with only four of the ten
provisions contained in the MOU.  The Texas Department of Banking's examination
conducted on July 17, 1995, found partial compliance with one provision of the
MOU and nine provisions of the MOU were found to be in noncompliance.  The
examination report dated July 7, 1995, as well as Deputy Commissioner James'
letter of September 26, 1995 identifies other violations of law and banking
regulations.  Finally, Mr. James solicited a further response from the Board
concerning compliance with the provisions of the MOU and indicated that after
such response was reviewed, the Board would be advised what additional action,
if any, would be taken by the Texas Department of Banking to effect compliance.
The Bank was also advised that the Texas Department of Banking would schedule an
examination no later than the first quarter of 1996 to monitor the progress of
compliance with the MOU.  Other than the matters described in this Schedule 2.16
and the deficiencies and violations of law and regulations outlined in the
examination reports and correspondence described in Section 2.16, the Bank is
unaware of any other violations, or possible violations of banking statutes or
regulations.  The Board has retained James Sexton, Austin, Texas, a former Texas
Banking Commissioner, to assist the Board as an outside consultant with regard
to compliance with the MOU and certain other matters raised in the September 26,
1995 letter from Deputy Commissioner James.

compensation payable" which was not reflected on certain quarterly regulatory
call reports filed during 1995.

                      AGREEMENT AND PLAN OF REORGANIZATION


     This Agreement and Plan of Reorganization (hereinafter called the
"Agreement") dated as of January 9, 1996, is executed by and between Texas State
Bank, McAllen, Texas, a Texas banking association ("Texas State Bank") and The
Border Bank, Hidalgo, Texas, a Texas banking association ("Border Bank").  Texas
State Bank is a wholly owned subsidiary of Texas Regional Bancshares, Inc., a
Texas corporation ("Texas Regional"), and Texas Regional joins into the
execution hereof for the purposes herein expressed.

     Subject to the fulfillment of the terms and conditions of this Agreement,
the undersigned shareholders of Border Bank (sometimes individually called a
"Shareholder" or collectively the "Shareholders") join into the execution hereof
for the purposes set forth in section 9.11 herein.


                              W I T N E S S E T H:

     This Agreement provides for the merger of Border Bank with and into Texas
State Bank, pursuant to the terms of this Agreement and Plan of Reorganization.
As a result of the merger, the shareholders of Border Bank, will receive an
aggregate of $20,500,000.00 in cash (subject to adjustment and calculated and
payable as herein provided).  The aggregate consideration shall be exchanged by
Texas State Bank for all of the outstanding shares of Border Bank capital stock,
and, upon the closing of the transaction, Border Bank will be merged with and
into Texas State Bank and Border Bank will cease its separate existence.

     As a result of the merger transaction, all rights, privileges, immunities,
powers and franchises of each of Texas State Bank and Border Bank shall be
merged into Texas State Bank as the surviving banking association.  Without any
other action, at the Effective Time, Texas State Bank shall be vested with all
property, real, personal and mixed, of the merging associations and shall
thereafter possess all of the interests, both public and private, of each of the
merging associations, and all claims of creditors of each of Border Bank and
Texas State Bank shall survive and any liens shall be preserved unimpaired in
Texas State Bank as the surviving association.  All of the foregoing shall be
effected pursuant to and as set forth in this Agreement and in an Agreement of
Merger (the "Merger Agreement") to be executed by and among the Corporation,
Border Bank and Texas State Bank, the form of which is attached hereto as
SCHEDULE 1.1.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements herein contained, the parties hereto agree as follows:

<PAGE>

                                    ARTICLE 1

                                 PLAN OF MERGER

     A.   THE MERGER.  Upon and subject to the terms and provisions hereof, at
the Effective Time, as hereafter defined, Border Bank shall be merged with and
into Texas State Bank (the "Merger"), with the effect that the separate
existence of Border Bank shall cease.  Texas State Bank and Border Bank, shall
each execute and deliver the Merger Agreement in the form attached hereto as
SCHEDULE 1.1 (the "Merger Agreement") as soon as reasonably practicable
following the execution and delivery hereof.  The Merger Agreement shall provide
for the conversion, on the Effective Date (as hereinafter defined), of all of
the outstanding shares of Border Bank capital stock into the right to receive
the Total Consideration, as hereafter defined.  At the Effective Time of the
Merger, the rights of the shareholders of Border Bank shall, without the
requirement of further action on the part of the shareholders, immediately be
converted into the right to receive cash consideration, as herein provided, for
each share of Border Bank held by such shareholder of record as of the Effective
Time and such shareholder shall cease to be a shareholder of Border Bank and
such share certificate shall for all purposes be deemed only to represent a
right to receive cash pursuant to this Agreement and the Merger Agreement.

     B.   CONSIDERATION.  Upon consummation of the merger, each share of Border
Bank outstanding shall be converted into the right to receive cash consideration
as herein provided.  The consideration to be paid by Texas State Bank shall be
$102.50 per share (the "Per Share Consideration") which consideration shall be
exchanged for each of the 200,000 outstanding shares of Border Bank, for an
aggregate consideration of $20,500,000.00 (the "Total Consideration"), adjusted
as herein provided for amounts attributable to shareholders exercising
dissenters' rights of appraisal.

          1.   An amount equal to the Per Share Consideration (adjusted as
     herein provided for amounts attributable to shareholders exercising
     dissenters' rights of appraisal) shall be paid by Texas State Bank to
     each Border Bank shareholder who has not exercised his, her or its
     dissenters' rights of appraisal upon surrender of such shareholder's
     share certificate or certificates evidencing shares of Border Bank
     stock.  Such amount shall be payable at the time of Closing to
     shareholders who have surrendered such share certificates at or prior
     to the date of Closing, by check made payable to each shareholder and
     mailed to such shareholder at the shareholder's address as stated on
     the stock transfer records of Border Bank, or (if an account is
     designated by such shareholder not less than twenty days prior to the
     date of Closing) by direct deposit or wire transfer into such account
     on the date of Closing.  Amounts payable to shareholders who surrender
     their share certificates following the date of Closing shall be paid
     within ten days following receipt of the shareholder's share
     certificate.  The stock transfer records of Border Bank shall for all
     purposes be closed as of the Effective Time, and no transfer of record
     of any of the shares of Border Bank capital stock shall take place
     thereafter.

<PAGE>

          2.   Any amounts that would otherwise have been payable pursuant
     to section 1.2.1 or 1.2.2 to any shareholder of Border Bank who has
     exercised his, her or its dissenters' rights of appraisal pursuant to
     applicable provisions of law shall be retained by Texas State Bank
     until such shareholder relinquishes his, her or its right of dissent,
     at which time the provisions of section 1.2.1 and 1.2.2 shall apply,
     except that the date of payment for such shares shall be extended to
     not less than ten days following the date of relinquishment of such
     dissenters' rights.  In the event that a shareholder of Border Bank
     exercises his, her or its dissenters' rights, if such shareholder
     receives as consideration for his or her shares an amount per share in
     excess of the Per Share Consideration, the amount payable to other
     shareholders in consideration of the merger shall be adjusted as
     follows:  the Total Consideration shall be reduced by the full amount
     payable to the dissenting shareholder and such adjusted Total
     Consideration shall be divided by the number of shares held by
     shareholders not exercising dissenters' rights to determine the amount
     of Per Share Consideration to be paid to all such other shareholders.

          3.   Any amounts payable to shareholders who surrender their
     share certificates after the date of Closing shall not bear interest
     attributable to periods either before or after the date of Closing.

     C.   CLOSING.  The closing ("Closing") of the transactions contemplated by
this Agreement shall be effected on the latest of the following dates, or as
promptly thereafter as reasonably practicable (the "Closing Date"):

          1.   March 31, 1996;

          2.   The thirtieth calendar day after the date of approval by the
     Federal Reserve Board as required by Section 7.02 herein; or

          3.   Such date as may be prescribed by the Federal Reserve Board,
     the Texas Banking Department or by any other federal or state agency
     or authority pursuant to an applicable federal or state law, order,
     rule or regulation, prior to which consummation of the transactions
     provided herein may not be effected; or

          4.   If the transactions contemplated by this Agreement are being
     contested in any legal proceeding and Texas State Bank, pursuant to
     Section 7.02 hereof, has elected to contest the same, then the date
     that such legal proceeding has been brought to a conclusion favorable,
     in the judgment of Texas State Bank, to the consummation of the
     transactions contemplated hereby; or

          5.   Such other date as the parties may select by mutual
     agreement.

The Closing shall take place at the offices of Texas State Bank, Kerria Plaza,
Suite 301, 3700 N. Tenth Street, McAllen, Texas, on the Closing Date, or at such
other place as shall be

<PAGE>

mutually agreeable.  If such Closing shall not have been accomplished on or
before June 30, 1996, this Agreement, and the Merger Agreement if executed and
delivered prior thereto, shall, at the election of either party hereto by
written notice, terminate and be of no further force or effect.  In addition,
Border Bank may terminate this Agreement and the Merger Agreement if Texas
Regional fails to file a registration statement with the Securities and Exchange
Commission, pursuant to which Texas Regional proposes to offer for sale shares
of Texas Regional capital stock with an estimated price that will yield an
aggregate of $40,000,000.00 in proceeds to Texas Regional, within forty-five
days following the date of Texas Regional's receipt of audited financial
statements for both Border Bank and First State Bank and Trust Company, Mission,
Texas in each case accompanied by the unqualified report of KPMG Peat Marwick,
for fiscal years ended December 31, 1995, 1994 and 1993; PROVIDED THAT Border
Bank may exercise the right of termination in this sentence only if such right
is exercised by written notice to Texas State Bank within ten days following
expiration of such forty-five day period.  Any termination which occurs through
no fault of any of the parties to this Agreement or the Merger Agreement shall
be without liability to any of the parties hereto or to the Merger Agreement,
except for the obligation of Texas State Bank to make certain payments required
pursuant to section 5.7 hereof.  This Agreement and the Merger Agreement may be
terminated at any time prior to the Effective Date by the mutual action of the
respective Boards of Directors of Border Bank and Texas State Bank.

     D.   EFFECTIVE DATE.  The parties hereto agree to take, on or prior to the
Closing Date, all such action, and to execute and deliver all such instruments
and documents, as may be necessary or advisable, on the advice of counsel, to
cause the Merger Agreement, subject to consummation of the Closing, to become
effective as soon as practicable after the Closing Date.  The merger shall
become effective at the time specified for consummation of the merger (herein
referred to as the "Effective Time") in the order to be issued by the Texas
Banking Department.

     E.   EFFECT OF MERGER.  As a result of the merger, Border Bank's assets and
business shall be acquired by Texas State Bank, free and clear of any and all
liens, claims or encumbrances.


                                    ARTICLE 2

                 REPRESENTATIONS AND WARRANTIES OF BORDER BANK

     Border Bank hereby represents and warrants to Texas State Bank as follows:

     A.   ORGANIZATION OF BORDER BANK.  Border Bank is a Texas state banking
association, duly organized and existing under the laws of the state of Texas,
and has full power and authority (including all licenses, franchises, permits
and other governmental authorizations which are legally required) to own its
properties and to engage in the business and activities now conducted by it,
including its commercial banking business.  Border Bank has branch licenses and
all other authority necessary to own and operate branch bank facilities operated
by Border Bank.  A list of the branches presently operated by Border Bank,
together with a list of licenses

<PAGE>

pending for operation of additional branch facilities are included on SCHEDULE
2.1.  True and complete copies of the Articles of Association and Bylaws of
Border Bank, as amended to date, have been delivered to Texas State Bank, or (to
the extent not previously delivered) Border Bank covenants to deliver the same
to Texas State Bank within 15 days following the date hereof.  Border Bank (i)
is duly authorized to conduct a general banking business, in accordance with its
charter, subject to the supervision of the Texas Banking Department, the Federal
Deposit Insurance Corporation and other applicable regulatory authorities; (ii)
is an insured bank as defined in the Federal Deposit Insurance Act; and (iii)

has full power and authority (including all licenses, franchises, permits and
other governmental authorizations which are legally required) to engage in the
business and activities now conducted by it.  Except as disclosed in SCHEDULE
2.1, Border Bank has no subsidiaries or affiliates, owns no voting securities of
any other corporation, and is not a member of any joint venture or partnership.
Border Bank is not a reporting company under the Securities Exchange Act of
1934, as amended (the "1934 Act").

     B.   CAPITALIZATION AND OWNERSHIP.  The authorized capital stock of Border
Bank consists of 200,000 shares (the "Shares") of capital stock, par value
$20.00 per share, all of which are duly authorized, validly issued and
outstanding, fully paid, nonassessable, and are owned beneficially and of record
by the persons named in the shareholder list previously delivered by Border Bank
to Texas State Bank.  The Shares have not been issued in violation of the
preemptive rights of any stockholder.  There are no outstanding options,
warrants, conversion rights, calls or commitments of any kind obligating Border
Bank to issue, directly or indirectly, additional shares of its capital stock,
and no authorization therefor has been given.  Border Bank does not have any
outstanding commitment or obligation to repurchase, reacquire or redeem any of
its outstanding capital stock.  The undersigned common shareholders of Border
Bank have joined into the execution hereof to evidence their consent to and
written approval of the transaction on the conditions herein described, and to
evidence their agreement to vote for and support the approval of the transaction
(on the conditions herein described) at the special shareholders' meeting to be
called to consider the merger.  The undersigned own beneficially and of record
not less than 68% of the outstanding common stock of Border Bank, and the
holders of common stock of Border Bank are the only shareholders who have the
right to vote on the proposed merger of Border Bank with and into Texas State
Bank.

     C.   FINANCIAL STATEMENTS AND RECORDS.

          1.   Border Bank has delivered to Texas State Bank (i) the unaudited
balance sheet of Border Bank as of December 31, 1994 (the "December 31, 1994
Balance Sheet"), and the related unaudited statements of income, changes in
stockholders' equity and changes in financial position for the year then ended,
together with the notes thereto; and (ii) the unaudited regulatory reports of
condition of Border Bank as of December 31, 1993, 1992 and 1991, and the related
unaudited statements of income and changes in equity capital for each of the
years then ended.  These financial statements fairly present the financial
position of Border Bank as of the dates thereof and the results of its
operations for the periods indicated.  In addition, Border Bank has delivered to
Texas State Bank its unaudited balance sheet and regulatory report of condition
as of September 30, 1995 (collectively, the "September 30, 1995 Balance Sheet")
and the related unaudited statements of income, changes in stockholders' equity
and changes in

<PAGE>

financial position for the twelve-month period then ended.  In the opinion of
the management of Border Bank, these financial statements also fairly present
the financial position of Border Bank as of the date thereof and the results of
its operations for the period indicated and the financial records upon which
such financial statements are based have been kept in accordance with prudent
banking practices and the past practices of Border Bank.  Except as disclosed in
SCHEDULE 2.3.1, the September 30, 1995 Balance Sheet and related financial
statements for the nine-month period then ended, have been prepared in
accordance with generally accepted accounting principles, consistently applied.
The December 31, 1994 Balance Sheet and the September 30, 1995 Balance Sheet,
and the financial statements for the twelve and nine-month periods then ended,
described above are collectively referred to hereinafter as the "Border Bank
Financial Statements."  Except as set forth in SCHEDULE 2.3.1, the Border Bank
Financial Statements do not, as of the dates thereof, include any material
assets or omit to state any material liability, absolute or contingent, the
inclusion or omission of which renders such financial statements, in light of
the circumstances under which they were made, materially misleading.  Without
limiting the generality of the foregoing, Border Bank specifically represents to
Texas State Bank that, except as set forth in SCHEDULE 2.3.1, Border Bank has no
liabilities, either accrued, contingent or otherwise, which, individually or in
the aggregate, are material, which have not been reflected in the Border Bank
financial statements (including the September 30, 1995 Balance Sheet) or which
have been incurred in the ordinary course of business since the date of the
September 30, 1995 Balance Sheet.

          2.   Except as set forth in SCHEDULE 2.3.2, since December 31, 1994,
there have not been any material changes in the financial condition, results of
operations, business or prospects of Border Bank, other than changes in the
ordinary course of business, none of which individually or in the aggregate has
been materially adverse, nor have there been any other events or conditions of
any character which have individually or in the aggregate materially and
adversely affected the financial condition, results of operations, business or
prospects of Border Bank.

          3.   The books and records of Border Bank reflect the transactions to
which it is or was a party or by which its properties are or were bound, and, to
the extent applicable, such books and records are and have been properly kept
and maintained in accordance with the law and prudent banking principles except
as otherwise disclosed in SCHEDULE 2.3.3.  As of the date hereof and as of the
Closing, all of the minute books of Border Bank are and will be complete,
accurate and current.

          4.   Border Bank has no trust powers and does not operate a trust
department.

     D.   LOANS.

          1.   All Loans included in the assets of Border Bank, and all
commitments to make Loans by Border Bank (including leasing transactions and off
balance sheet lending transactions such as letters of credit), have been made in
the ordinary course of business of Border Bank and do not present more than the
normal risk of uncollectibility or other unfavorable features, except as
disclosed in Schedule 2.4.1.

<PAGE>


          2.   All Loans to directors, officers and beneficial owners of 5% or
more of the outstanding capital stock of Border Bank, and loans to any person or
company related to or affiliated with any such person, are listed on Schedule
2.4.2.  The Loans listed on Schedule 2.4.2 do not present more than the normal
risk of uncollectibility or other unfavorable features.

          3.   Border Bank's reserves for loan losses have been calculated in
accordance with all applicable rules and regulations.  In the reasonable opinion
of the management, officers and directors of Border Bank, the reserve for loan
losses shown on the September 30, 1995 Balance Sheet is adequate in all respects
to provide for all losses on loans outstanding as of the date of September 30,
1995 Balance Sheet.

     E.   PROPERTIES.  Border Bank has good and indefeasible title to all assets
and properties, whether real or personal, tangible or intangible, which it
purports to own, including without limitation, all assets and properties
reflected on the September 30, 1995 Balance Sheet or acquired subsequent thereto
(except to the extent such assets and properties have been disposed of for fair
value in the ordinary course of business since the date of the September 30,
1995 Balance Sheet), subject to no liens, mortgages, security interests,
encumbrances, easements, title imperfections, or charges of any kind except (i)
as noted in the September 30, 1995 Balance Sheet or the notes to the Border Bank
Financial Statements, (ii) statutory liens not yet delinquent, (iii) security
interests granted incident to borrowings by Border Bank from Federal Reserve
Banks or to secure deposits of funds by federal, state or other governmental
agencies, and (iv) minor defects and irregularities in title and encumbrances
which do not materially impair the use thereof for the purposes for which they
are held and such liens, mortgages, security interests, encumbrances and charges
as are not, in the aggregate, material to the assets and properties of Border
Bank.  Except as disclosed on SCHEDULE 2.5, all improvements, buildings and
structures located on real estate owned by Border Bank, and the use by Border
Bank of such real estate, together with such improvements, buildings and
structures, in the manner heretofore and currently used by Border Bank, conform
in all material respects to applicable federal, state and local laws and
regulations (including applicable environmental laws and regulations), zoning
and building ordinances and health and safety ordinances, and such real estate
is zoned for the various purposes for which such real estate is currently being
used.  Except as disclosed on SCHEDULE 2.5, all such improvements, buildings and
structures located on real estate owned by Border Bank, and all of the material,
tangible personal property owned by Border Bank, are in good operating condition
and repair, reasonable wear and tear excepted.  Listed on SCHEDULE 2.5 are all
policies of title insurance covering such properties.

     F.   ENVIRONMENTAL MATTERS.  Neither any Environmental Hazards nor any
Hazardous Materials Contamination exist on any real property owned by Border
Bank (including any owned by and used in connection with the business of Border
Bank and any foreclosed properties owned by Border Bank), or on any real
property used by the Bank in connection with the business of Border Bank or on
any adjacent property, as a result of any Environmental Hazards on or emanating
from the Real Property.  The real properties described in the preceding sentence
are sometimes collectively referred to as the "Real Property."  Included on
SCHEDULE 2.6 is a list of any environmental survey or report related to any of
the Real Property, true, correct and

<PAGE>

complete copies of which have been provided to Texas State Bank.  As used in
this Agreement, the term "Environmental Hazards" shall mean (i) any "hazardous
waste" as defined by the Resource Conservation and Recovery Act of 1976 (42
U.S.C. Section 6901 et seq.), as amended from time to time, and regulations
promulgated thereunder; (ii) any "hazardous substance" as defined by the
Comprehensive Environmental Response, Compensation and Liability Act of 1980 (42
U.S.C. Section 9601 et seq.) ("CERCLA"), as amended from time to time, and
regulations promulgated thereunder; (iii) any toxic substance regulated by the
Toxic Substances Control Act (15 U.S.C. Section 2601 et seq.), as amended from
time to time, and regulations promulgated thereunder; (iv) gasoline, diesel fuel
or other petroleum hydrocarbons; (v) asbestos and asbestos containing materials,
in any form, whether friable or non-friable; (vi) polychlorinated biphenyls;

severally, to indemnify, defend and hold harmless Border Bank and its officers,
directors, employees, agents and attorneys from and against any and all losses,
claims, damages, expenses or liabilities to which Border Bank may become subject
(including any arising as a result of the consummation of the transaction
described in this Agreement and any arising under the Securities Act of 1933 or
the Securities Exchange Act of 1934, or any rule, order or regulation pursuant
thereto), arising out of or based upon (i) breach of a representation, warranty,

          3.   Each of Texas State Bank and Border Bank (to the extent of an
indemnification obligation hereunder, herein referred to as the "Indemnifying
Party") will indemnify the other parties hereto and each of such other party's
directors, officers and each person who "controls" such other party within the
meaning of such term as used in Section 15 of the 1933 Act (such persons being
herein called the "Indemnified Parties") and will defend and hold the
Indemnified Parties harmless from and against any and all losses, claims,
damages, expenses, or liabilities to which the Indemnified Parties may become
subject under the common law or otherwise insofar as:

<PAGE>

               a.   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 communications to
     shareholders, or any application or statement filed pursuant to this
     Agreement or arising out of or based upon the omission or alleged
     omission to state therein a material fact necessary in order to make
     the statement therein, in the light of the circumstances in which they
     were made, not misleading, but only insofar as any such statement or
     omission was made in reliance upon and in conformity with information
     furnished by the party against whom indemnification is sought
     hereunder for use therein; and

               b.   such losses, claims, damages, expenses, or liabilities
     are incurred by the Indemnified Parties (or are losses, claims,
     damages, expenses or liabilities with respect to which the Indemnified
     Parties become subject), under the common law or otherwise, arising
     out of or in any way attributable to the breach of any warranty or
     representation made by such party herein or pursuant to the terms
     hereof, or the failure of such party to perform any covenant or
     obligation contained in this Agreement.

          4.   The indemnification obligations contained herein shall expressly
include the obligation of the Indemnifying Party to reimburse the Indemnified
Party for any legal or other expenses (including counsel fees) reasonably
incurred by them in connection with investigating or defending against any and
all such losses, claims, damages, expenses, liabilities or actions whether or
not resulting in any liability.

          5.   The Indemnified Parties shall, within twenty (20) days after the
receipt by them of any notice of any claim or of the commencement of any
litigation in respect of which indemnity may be sought hereunder, notify the
Indemnifying Party thereof.  The omission to notify the Indemnifying Party of
any such claim or litigation shall relieve the Indemnifying Party from any
liability which it may have under the indemnity agreement contained herein, but
shall not relieve the Indemnifying Party from any other liability which it may
have to the Indemnified Parties, other than that raised in any such claim or
litigation explicitly or by reasonable implication or that which may estop the
Indemnifying Party from raising and effecting some defense it might otherwise
have raised had such notice been properly given.  If any such litigation shall
be brought against the Indemnified Parties and if the Indemnified Parties shall
notify the Indemnifying Party of the commencement thereof, the Indemnifying
Party shall be entitled, unless in the opinion of counsel to the Indemnified
Party there exist issues as to which the interests of the Indemnified and
Indemnifying Parties are adverse, to participate in (and, to the extent that it
shall wish, to direct) the defense thereof at its own expense, but such defense
shall be conducted by counsel satisfactory to the Indemnified Parties.

          6.   The indemnity agreement contained in this Article shall survive
any investigation made by or on behalf of any Indemnified Party.

          2.   Texas State Bank agrees to provide any and all information as may
be reasonably required by Border Bank for purposes of communications with
shareholders of Border Bank pending the Closing and for purposes of the proxy
statement related to obtaining the approval by Border Bank shareholders of the
transaction herein described (collectively, the "Texas State Information").
Texas State Bank hereby agrees that, upon delivery to Border Bank, the Texas
State Information shall not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they are made, not misleading.

     D.   ACCESS.  From and after the date of this Agreement, Border Bank shall
afford to the officers, attorneys, accountants and other authorized
representatives of Texas State Bank full and free access to the properties,
books, contracts, commitments and records of Border Bank at all reasonable times
during business hours, and such representatives of Texas State Bank shall be
furnished with true and complete copies of the same and with all other
information concerning the affairs of Border Bank as such representatives may
reasonably request.  Any such information treated as confidential by Border Bank
shall be kept confidential by the representatives of Texas State Bank (and shall
be used by them only in connection with this Agreement and the transactions
contemplated hereby) except to the extent that (i) it was already known to such
representatives when received, (ii) it hereafter becomes lawfully obtainable
from other sources, or (iii) it is disclosed by Texas State Bank in any document
filed with the Securities and Exchange Commission, the Federal Reserve Board or
any other governmental agency or authority.  In the event the transactions
contemplated by this Agreement and the Merger Agreement are not consummated,
Texas State Bank agrees to return to Border Bank any confidential information
delivered by Border Bank to Texas State Bank pursuant to this Section.

     E.   ENVIRONMENTAL INSPECTION.  Border Bank expressly agrees to supply
Texas State Bank with historical and operational information regarding the real
properties owned or operated by, or used in connection with the operation of the
business of, Border Bank, and any premises heretofore used in connection with
the operation of the business of Border Bank, and any other properties included
in the Real Property, including (but not limited to) any environmental tests or
surveys made of such properties.  Border Bank agrees to cooperate with any
reasonable request of Texas State Bank related to site assessment or site review
related to any environmental matter or investigation, including the making
available of such personnel of Border Bank as Texas State Bank may reasonably
request.  At Texas State Bank's discretion, Texas State Bank may arrange for one
or more independent contractors to conduct tests of the Real Property and any
other premises now or heretofore used in connection with the business of Border
Bank in order to identify any presence of, or present or past release or
threatened release of, any waste materials or any chemical substances,
including, without limitation, any Environmental Hazards.  Any such test may be
done at any time, or from time to time, upon reasonable notice and under
reasonable conditions, which do not impede the performance of the tests.  Such
tests may include both above and below ground testing for environmental damages
or the presence of Environmental Hazards or Hazardous Material Contamination or
such other tests as Texas State Bank may deem reasonably necessary.  Any and all
costs of third parties associated with


<PAGE>

obtaining such information shall be borne equally by Texas State Bank and Border
Bank.  In the event such tests indicate the presence of Hazardous Material
Contamination, the parties shall endeavor to obtain a reasonably reliable
estimate of the cost of remediating or removing such Hazardous Material
Contamination prior to the Closing.  In the event that such estimated cost is
less than $25,000, Border Bank shall accrue the cost thereof as an expense prior
to Closing for purposes of calculating the minimum net worth required at
Closing, in which event the parties shall proceed to Closing on the terms and
conditions described in this Agreement.  In the event that such estimated cost
exceeds an aggregate of $25,000, Texas State Bank may elect to either (i)
proceed with the transaction on the terms and conditions herein provided,
without modification, in which event the parties shall perform their respective
obligations as herein provided, without modification; or (ii) proceed with the
Closing on the terms and conditions herein provided, on the further condition
that Border Bank either fully remediate and remove the Hazardous Material
Contamination prior to Closing or (at Texas State Bank's option) accrue the full
cost thereof as an expense prior to Closing for purpose of calculating the
minimum net worth required at Closing, and in either of such events Border Bank
shall be entitled to acquiesce in such remediation and removal (or if Texas
State Bank has so elected, the accrual of the cost thereof), or Border Bank
shall be entitled to unilaterally terminate this Agreement.  In the event that
the cost of remediation exceeds $25,000, or if the parties are unable to obtain
a reasonably reliable estimate of the remediation and removal cost prior to
Closing, Texas State Bank shall be entitled to exercise the options set forth in
the preceding sentence, or to terminate this Agreement without further
liability.

     F.   ACTION BY BORDER BANK PRIOR TO CLOSING.

between the date hereof and the date of Closing, Border Bank specifically
covenants and agrees that Border Bank will not incur any indebtedness (other
than deposit liabilities owed to deposit customers in the ordinary course of
business and trade accounts payable incurred in the ordinary course of business)
or significant expenses outside of the ordinary course of business of Border
Bank, nor will Border Bank increase expenses in any material way (either
individually or in the aggregate), nor will Border Bank make any changes in its

without the prior written consent of Texas State Bank, Border Bank (i) will not
permit any change to be made in its charter or Bylaws; (ii) will not take any
action following the date hereof that would have required that the action, or

terminate for failure of a condition specified in section 6.4 (Regulatory
Approvals), section 6.7 (Due Diligence Review; No Material Adverse Change),
section 6.11 (Fairness Opinion), or section 6.14 (Financing) hereof, or as a

     and of record immediately prior to the Effective Time by the Border

     all such shares shall be owned and held by the Company.  The existing
     shares of Border Bank shall be cancelled.

          (d)  The capital of Border Bank and Texas State Bank immediately
     prior to the merger shall be combined as the capital of the Surviving
     Bank, subject to such adjustment as may be necessary to properly
     account for the transaction as a purchase for financial accounting
     purposes.

          (e)  All rights of the holders of outstanding certificates of
     Border Bank common stock under the plan of merger described in this
     Agreement shall be determined from the stock transfer records of
     Border Bank as of the close of business on the date specified in the
     approval letter to be issued by the Federal Reserve Board, or the
     Texas Department of Banking, or other applicable regulatory authority,
     and no transfer of record of any of the shares of Border Bank common

                                   Section 9.

     Effective as of the Effective Time and until amended by an appropriate
action taken by or on behalf of the Surviving Bank, the Articles of Association
of the Surviving Bank shall be the Articles of Association of Texas State bank
as in effect as of the Effective Time.  The Bylaws of the Surviving Bank shall

statutory dissenters' appraisal rights, Texas State Bank shall be entitled, but
shall not be obligated, to elect to terminate this Agreement, in which case the

     1.   The unaudited call reports for the periods ending December 31, 1993,

credit, unasserted claims or for pending or overtly threatened litigation.

     3.   In the past, the Bank has elected not to amortize loan costs over the
life of the loan as contemplated by FASB 91; therefore, the unaudited reports of

     1.   The Bank is not under examination, nor has it been notified of any
examination or any proposed examination by any taxing authority.

     2.   The Bank computes appropriate reserves for deferred taxes only on a

                                    CONTRACTS


      (i) EMPLOYMENT CONTRACTS.  The Bank does not have written employment
          contracts with any employees.  The Bank has previously furnished Texas
          State Bank with a list of current employees together with their
          salaries.  In addition to their respective salaries, the Bank has had
          a policy for many years of paying a bonus in an amount equal to 10% of
          each employee's salary.  This bonus is accrued on the books of the
          Bank and paid on December 15 of each year.  The Bank also participates
          in a cafeteria plan for the benefit of its employees.  This plan
          allows employees to set aside funds for medical expenses on a tax free
          basis.  The plan is a "control group" plan that also includes
          employees of an affiliate, First State Bank & Trust Co., Mission,
          Texas and Citizens State Bank of Roma, Texas.  The cafeteria plan
          covers life, accidental death and dismemberment, medical and dental.
          A policy maintained through Jefferson Pilot Insurance Company covers
          employee life, accidental death, dismemberment and health claims.  The
          Bank pays 100% of the premiums for officers and their dependents.  The
          Bank pays one-half of the premiums for other employees and their
          dependents.  Officers of the Bank are reimbursed for personal
          automobile usage and certain officers are allowed to use Bank credit
          cards for expenses related to the business of the Bank.  Certain
          athletic club dues and related expenses are also paid on behalf of
          certain officers.  Brent Bottom, President of the Bank is also
          furnished with a Bank owned vehicle for his use.  Employees with over
          15 years employment are afforded a three week paid vacation.  Other
          employees are afforded a two week paid vacation.

     (ii) OTHER EMPLOYEE BENEFITS.  The Bank has one deferred compensation
          agreement for the benefit of a retired Bank employee.  The agreement
          provides for retirement benefits to be paid to the employee or a
          designated beneficiary or estate if death occurs prior to payment of
          the full amount of deferred compensation on reaching age 65.  The
          agreement entered into on January 1, 1990, commenced payments to the
          retired employee of approximately $1,112.50 per month on March 15,
          1995, continuing monthly thereafter for 180 months.  The Bank owns and
          is the beneficiary of a life insurance policy on the employee covered
          by the deferred compensation agreement.  See Schedule

<PAGE>

          2.11 for description of this life insurance policy.  The life
          insurance policy face value is in an amount approximately equal to the
          total benefits paid under the agreement.

    (iii) MATERIAL LEASES OR LICENSES.

          None


     (iv) CONTRACTS OR COMMITMENTS FOR CAPITAL EXPENDITURES IN EXCESS OF
          $100,000.

          a)   EDS CONTRACT.  On September 13, 1994, the Bank and Electronic
               Data Systems Corporation ("EDS") entered into that certain
               Agreement for Information Technology Services (the "EDS
               Agreement").  The EDS Agreement provides for EDS to render
               various specified data processing services to the Bank for a
               fixed monthly rate of $5,796 per month for designated "basic"
               services plus additional charges for certain "optional" services
               that the Bank may call upon EDS to perform.  The initial term of
               the EDS Agreement is for a period of five years from September
               13, 1994.  Under Section 7.2 of the EDS Agreement, if 50% or more
               of the stock or assets of the Bank change hands, the EDS
               Agreement may be terminated "upon the consummation of such
               acquisition or on a mutually agreeable date thereafter."
               However, in the event of such termination, EDS is entitled  to
               receive liquidated damages, as described in Section 7.6.  Under
               Section 7.6, EDS is entitled to receive the SUM of (a) all actual
               disengagement costs and expenses reasonably incurred by EDS in
               connection with termination PLUS a 25% "management fee" on such
               costs; AND (b) an amount equal to 80% of the total compensation
               "which would have been paid to EDS" under the EDS Agreement
               during the remainder of its term.  (The EDS Agreement provides
               that EDS' total expected compensation is to be determined by
               multiplying the number of months remaining in the initial term by
               the average monthly charge to the Bank for the 12 months
               preceding the month in which notice of termination

               was given.)

                       REGULATORY MATTERS AND EXAM REPORTS

     1.   The Board of Directors of the Bank and the Banking Commissioner of
Texas entered into a Memorandum of Understanding ("MOU") on October 8, 1993.
The MOU was issued as a result of specific criticisms and alleged deficiencies
reflected in the June 28, 1993, Report of Examination issued by the Texas
Department of Banking.  The MOU documents an agreement reached between the
Commissioner and the Board of Directors concerning nine management goals and
corrective actions with respect to the Bank and sets forth time frames within
which these goals and corrective actions were to be accomplished.  The Board of
Directors, individually and collectively, agreed to cause management of the Bank
to take corrective actions and to use best efforts to accomplish the goals which
were set forth in the MOU.  In subsequent examination reports and in a letter
dated September 27, 1995, the FDIC has criticized the Board's compliance with
certain provisions of the MOU.  The Texas Department of Banking has also
criticized compliance with the MOU.  In the letter dated September 27, 1995,
Kenneth L. Walker, Regional Director of the FDIC, advised the Board of Directors
that the FDIC's examination of June 30, 1995, found that the Bank and Board were
not in satisfactory compliance with the MOU.  The examination report dated June
30, 1995, as well as Mr. Walker's letter of September 27, 1995 identifies other
violations of law and banking regulations.  Finally, Mr. Walker solicited a
further response from the Board concerning compliance with the provisions of the
MOU.  Other than the deficiencies described in this Schedule 2.16 and the
deficiencies and violations of law and regulations outlined in the examination
reports and correspondence described in Section 2.16, the Bank is unaware of any
other violations, or possible violations of banking statutes or regulations.
The Board has retained James Sexton, Austin, Texas, a former Texas Banking
Commissioner, to assist the Board as an outside consultant with regard to
compliance with the MOU and certain other matters raised in the September 27,
1995 letter from Mr. Walker.
