                                    SUMMARY

THE MEETING.

     This Prospectus/Proxy Statement is furnished in connection with the
solicitation of proxies by the Board of Directors of TB&T Bancshares, for use at
a special meeting of the shareholders of TB&T Bancshares to be held at the time
and place set forth in the foregoing notice and at any adjournments thereof.
This Prospectus/Proxy Statement is also a prospectus for the issuance and
distribution of shares of Texas Regional Common Stock at the closing of the
Merger of TB&T Bancshares with and into TRD, a subsidiary of Texas Regional, and
for the issuance and distribution of shares of Texas Regional Common Stock from
the escrow account created pursuant to the Holdback Escrow Agreement attached to
the Agreement.

     The following proposals will be considered and voted upon at the special
meeting of TB&T Bancshares shareholders:

          (1)  To approve, ratify, confirm and adopt the Agreement and Plan of
     Reorganization dated as of October 15, 1997, by and between Texas Regional
     and TB&T Bancshares (the "Agreement"), pursuant to which TB&T Bancshares
     will be merged with and into TRD, and to approve the merger of TB&T
     Bancshares' wholly-owned subsidiary, Texas Bank & Trust, with and into
     Texas Regional's wholly-owned subsidiary, Texas State Bank; and

          (2)  To consider and transact such other business as may properly come
     before the meeting and any adjournment thereof.

     The Board of Directors of TB&T Bancshares has fixed             , 1997 as
the record date for the determination of shareholders entitled to notice of and
to vote at the meeting and any adjournment thereof. As of such date, TB&T
Bancshares had 1,695,775 shares of capital stock issued and outstanding. There
is no other class of TB&T Bancshares stock authorized, issued or outstanding. As
of the date hereof, the TB&T Bancshares capital stock was held of record by
approximately 82 persons. Each share entitles the holder of record on the record
date to one vote as to the Merger and one vote as to any other proposal to be
voted on at the special meeting of TB&T Bancshares shareholders. The presence,
in person or by proxy, of the holders of a majority of the shares of TB&T
Bancshares is necessary to constitute a quorum at the meeting, and the
affirmative vote of at least two-thirds of the total outstanding shares of TB&T
Bancshares capital stock is required for approval of the merger.

     The TB&T Bancshares Board of Directors has unanimously approved the merger
and all of the members of the Board of Directors and certain parties related to
members of the Board of Directors have agreed to vote their shares of TB&T
Bancshares in favor of the Merger at the special meeting of the shareholders.
See "Information about TB&T Bancshares -- TB&T Bancshares Stock Ownership."
Because shareholders holding an aggregate of 1,388,104 shares, amounting to
81.9% of the total outstanding TB&T Bancshares shares, have agreed in the
Agreement to vote their shares in favor of the merger transaction, the
transaction is expected to be approved at the special meeting of the
shareholders.

VOTING.

     Proxies in the form enclosed are solicited by the TB&T Bancshares Board of
Directors. Any such proxy, if received in time for voting and not revoked, will
be voted at the meeting in accordance with the shareholder's instructions. If no
instructions are given on the proxy, the proxy will be voted in favor of the
Merger transaction. At present, TB&T Bancshares' Board of Directors knows of no
other matter to be presented at the meeting, but if other matters are properly
presented, the persons named in the proxy will vote or refrain from voting in
accordance with the recommendation of the TB&T Bancshares Board of Directors
pursuant to the discretionary authority conferred by the proxy.

     Proxies will be solicited initially by mail, and may also be solicited
personally, by telephone, facsimile transmission or other means by the
directors, officers and employees of TB&T Bancshares, who shall not be

                                       5
<PAGE>
specially compensated therefor. However, TB&T Bancshares will reimburse such
directors, officers and employees for any reasonable out-of-pocket expenses in
connection with the solicitation. Arrangements will be made with custodians,
nominees and fiduciaries for the forwarding of solicitation materials to the
beneficial owners of TB&T Bancshares capital stock held of record by such
persons. Expenses incurred in connection with the Merger, including those
attributable to the solicitation of proxies, will be paid by the party to the
Merger incurring the expense.

     Any TB&T Bancshares shareholder has the right to revoke his, her or its
proxy at any time before it is voted by giving written notice of such revocation
to the Secretary of TB&T Bancshares at the address of TB&T Bancshares set forth
herein.

     The close of business on                , 1997, has been fixed as the
record date for the determination of shareholders entitled to notice of and to
vote at the special meeting of the shareholders of TB&T Bancshares. At that
date, there were 1,695,775 shares of capital stock, par value $1.00 per share,
of TB&T Bancshares issued and outstanding, each of which is entitled to one vote
at the special meeting. At that date there were approximately 82 holders of
record of TB&T Bancshares capital stock.

     Under applicable provisions of Texas law, not less than two-thirds of the
issued and outstanding shares of capital stock of TB&T Bancshares present in
person or by proxy at a meeting of the shareholders is required for approval of
the Agreement and the transactions contemplated thereby, and such approval is
also solicited by this Prospectus/Proxy Statement and the accompanying proxy.
Execution of the proxy card by a TB&T Bancshares shareholder, if voted for the
merger and voted in accordance with those instructions, and will constitute the
approval required by Texas law. Shareholders dissenting from the merger of TB&T
Bancshares with and into TRD may be entitled to exercise dissenters' rights of
appraisal. See "Information About the Transaction -- Dissenters' Rights."

     As indicated above, shareholders holding a total of 81.9% of the
outstanding shares of TB&T Bancshares capital stock have agreed to vote their
TB&T Bancshares shares in favor of the Agreement at the TB&T Bancshares
shareholders meeting. See "Information About the Transaction -- Joinder by
Certain Shareholders."

     Texas Regional is the sole shareholder of TRD. Texas Regional, as the sole
shareholder of TRD, has already approved the transaction, subject to the
approval of applicable regulatory authorities.

DISSENTERS' RIGHTS.

     Holders of TB&T Bancshares capital stock who timely object to the Merger,
and who otherwise comply with the provisions of the Texas Business Corporation
Act (the "TBCA") will be entitled to exercise dissenters' rights. Each step
required to exercise dissenters' rights must be taken in the precise order
prescribed by the statutes set forth in Annex B for a shareholder to perfect
his, her or its dissenters' rights of appraisal. Shareholders of TB&T Bancshares
who exercise their dissenters' rights of appraisal will only be entitled to
receive cash for their shares of TB&T Bancshares stock; they will not be
entitled to receive shares of Texas Regional stock. See "Information About the
Transaction -- Dissenters' Rights" and Annex B attached hereto.

     If shareholders of TB&T Bancshares holding an aggregate of greater than 2%
of the issued and outstanding TB&T Bancshares shares exercise dissenters'
rights, Texas Regional is entitled to refuse to consummate the Merger and
terminate the transaction. See "Information About the Transaction -- Other
Terms and Conditions."

THE AGREEMENT.

     The Agreement, which has been approved by the respective boards of
directors of TB&T Bancshares and Texas Regional, provides that TB&T Bancshares
will be merged with and into TRD. The summary of information relating to the
Agreement contained in this Prospectus/Proxy Statement is qualified in its
entirety by reference to the Agreement attached to this Prospectus/Proxy
Statement as Annex A, and the

                                       6
<PAGE>
Agreement is hereby incorporated into this Prospectus/Proxy Statement by this
reference. Shareholders of TB&T Bancshares are urged to read carefully the
entire Prospectus/Proxy Statement and all attachments.

     The Agreement provides that each outstanding share of capital stock of TB&T
Bancshares will be converted into and exchanged for the right to receive at
closing 0.1522126 of a share of Texas Regional Class A Voting Common stock (the
"Texas Regional Common Stock"). In addition, the Agreement provides that
0.0294605 of a share of Texas Regional Common Stock for each share of TB&T
Bancshares held shall be deposited into escrow pursuant to the Holdback Escrow
Agreement to be executed at the time of closing in the form attached to the
Agreement. The shares deposited into escrow will be either returned to Texas
Regional or distributed to the shareholders of TB&T Bancshares based upon the
disposition or other outcome of certain claims. See "Information About the
Transaction -- Terms of the Agreement," "Information About the
Transaction -- Holdback Escrow Agreement," and "Information About the
Transaction -- Federal Income Tax Consequences." Upon consummation of the
merger, TB&T Bancshares will be merged with and into TRD, and the current
shareholders of TB&T Bancshares will cease to be shareholders of TB&T Bancshares
and will be entitled to receive Texas Regional Common Stock in consideration of
their shares of TB&T Bancshares capital stock.

     Texas Regional anticipates that, immediately following the merger of TB&T
Bancshares with and into TRD, TB&T Bancshares' wholly owned subsidiary, Texas
Bank & Trust, will be merged with and into TRD's wholly owned subsidiary, Texas
State Bank. As part of the resolution to approve the merger of TB&T Bancshares
with and into TRD, the TB&T Bancshares shareholders will also be asked to
consider the approval of the merger of Texas Bank & Trust with and into TRD's
subsidiary, Texas State Bank. As a result of the mergers, Texas Regional will
wholly own TRD, the resulting entity in the merger with TB&T Bancshares, and TRD
will in turn wholly own Texas State Bank, the resulting entity in the merger
with Texas Bank & Trust.

     All of the directors of TB&T Bancshares and all of the directors of Texas
Regional have voted in favor of the Agreement. Members of the TB&T Bancshares
Board of Directors and executive officers of TB&T Bancshares, and their
respective affiliates, own an aggregate of 82.0% of the outstanding shares of
Brownsville Bancshares capital stock. No present director or member of
management of TB&T Bancshares has notified Texas Regional of his or her
intention to oppose any action to be taken at the special meeting of the
shareholders of TB&T Bancshares. As of the date of this Prospectus/Proxy
Statement, a total of 1,695,775 shares of capital stock of TB&T Bancshares were
issued and outstanding. The Agreement and the Merger Agreement must be approved
and adopted by the holders of at least two-thirds of the outstanding capital
stock of TB&T Bancshares. Directors and certain shareholders of TB&T Bancshares,
holding in the aggregate 1,388,104 shares of TB&T Bancshares (amounting to an
aggregate of 81.9% of the issued and outstanding capital stock of TB&T
Bancshares), have agreed, pursuant to the Agreement, to vote their shares of
TB&T Bancshares capital stock in favor of the Merger at the special meeting of
the shareholders of TB&T Bancshares.

REASONS FOR THE MERGER.

     The Agreement is the result of arm's-length negotiations between
representatives of Texas Regional and TB&T Bancshares. Upon receipt of a
proposal from Texas Regional, the TB&T Bancshares Board of Directors carefully
evaluated the proposal and concluded that the proposed Merger with Texas
Regional was in the best interests of TB&T Bancshares and its shareholders for a
number of reasons.

     In evaluating the Texas Regional offer, TB&T Bancshares' Board of Directors
considered other transactions in the Rio Grande Valley area of Texas, as well as
transactions in other areas of Texas and elsewhere.

     Among the factors considered by the Board of Directors of TB&T Bancshares
was their limited market for TB&T Bancshares' stock. The outstanding common
stock of TB&T Bancshares is not widely held and

                                       7
<PAGE>
there is not an active trading market. By contrast, Texas Regional's common
shares are listed on the NASDAQ National Market System and there is an active
market for its stock.

     The Board of Directors of TB&T Bancshares also considered the competitive
market in which TB&T Bancshares operates. The banking industry in general and in
the Rio Grande Valley of Texas in particular is consolidating. TB&T Bancshares
competes with larger and more highly capitalized institutions. Its ability to
offer different products, compete for qualified personnel and develop a network
of branches would have required additional capital and possibly limited future
dividends. Furthermore, developing such an organization would require several
years. By merging with Texas Regional, TB&T Bancshares' shareholders would
become shareholders of an organization which is in a stronger competitive
position but which is nonetheless headquartered in the same area.

     For the reasons set forth above, the TB&T Bancshares Board of Directors
believes the Merger to be in the best interests of TB&T Bancshares'
shareholders. In fact, all of the members of the TB&T Bancshares Board of
Directors have agreed in the Agreement to vote their shares of TB&T Bancshares
stock in favor of the Merger at the special meeting of the TB&T Bancshares
shareholders. THE TB&T BANCSHARES BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
THE TB&T BANCSHARES SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER and has
authorized the consummation of the Merger subject to approval of the TB&T
Bancshares shareholders and the satisfaction of certain other conditions. See
"Information About the Transaction -- Reasons for the Merger."

CONDITIONS.

     The Agreement contains numerous conditions, including the receipt of
shareholder approval as described in this Prospectus/Proxy Statement, receipt of
certain governmental approvals, and certain other conditions which must be
satisfied or waived before the merger can be consummated. See "Information
About the Transaction -- Terms of the Agreement" and "Information About the
Transaction -- Other Terms and Conditions."

     Texas Regional is registered as a bank holding company under the Bank
Holding Company Act of 1956, as amended, and, as a result, the transaction is
subject to the approval of the Federal Reserve Board. Texas Regional has applied
to the Federal Reserve Board for approval of the merger of TB&T Bancshares with
and into TRD and has applied to the Texas Banking Department for approval of the
merger of Texas Bank & Trust with and into Texas State Bank. In           , the
Company was notified that its final application had been accepted for filing by
the Federal Reserve Board. Similarly, the Texas Banking Department on
          , accepted for filing the application of Texas State Bank for the
merger of Texas Bank & Trust with and into Texas State Bank.

     Each party's obligations under the Agreement is contingent upon the other
not having a material adverse change, prior to closing, in its condition,
financial position or business prospects. In addition, Texas Regional's
obligation to close the Merger is further contingent upon TB&T Bancshares having
a net worth at the time of closing, calculated in accordance with applicable
regulatory requirements, of not less than $3,980,000, increased by $25,000 per
month for each month elapsed during the period from September 30, 1997, until
the date of Closing. The Agreement also provides a number of other conditions to
each party's respective obligations to close the Merger transaction. For
example, Texas Regional may terminate the transaction and refuse to consummate
the Merger if shareholders holding in excess of 2% of the outstanding TB&T
Bancshares shares exercise dissenters' rights of appraisal. In addition, either
Texas Regional or TB&T Bancshares may terminate the transaction if the closing
of the Merger has not been accomplished on or before March 1, 1998. See
"Information About the Transaction -- Other Terms and Conditions."

TEXAS REGIONAL.

     Texas Regional is a Texas business corporation registered as a bank holding
company under the Bank Holding Company Act of 1956, as amended. Texas Regional
was incorporated in Texas in 1983, and commenced active operations as a bank
holding company in 1984. The address of Texas Regional's principal executive
office is Kerria Plaza, Suite 301, 3700 North 10th Street, McAllen, Texas 78501,
and its

                                       8
<PAGE>
telephone number is (956) 631-5400. The main banking office of Texas State Bank
is at 3900 North 10th Street, McAllen, Texas 78501.

     Texas Regional presently has 20,000,000 shares of Texas Regional Common
Stock authorized, of which a total of 13,110,639 shares are issued and
outstanding. In addition, there are options outstanding to acquire an aggregate
of 343,924 shares of Texas Regional Common Stock, and Texas Regional has
committed to issue up to an aggregate maximum of 985,000 shares of Texas
Regional Common Stock in connection with the pending acquisition of Brownsville
Bancshares, Inc. See "Information About Texas Regional -- Pending
Transactions." Texas Regional has authorized 10,000,000 shares of preferred
stock, but no shares of preferred stock are presently outstanding, and Texas
Regional has no present commitment to issue any shares of preferred stock. The
shares to be exchanged for shares of TB&T Bancshares capital stock as described
in the Agreement are authorized but unissued shares of Texas Regional Common
Stock.

     Texas Regional Common Stock is registered with the Securities and Exchange
Commission as required by section 12 of the Securities Exchange Act of 1934 (the
"Act"). As required by the Act and regulations promulgated under the Act,
Texas Regional makes certain periodic reports to the SEC, and files financial
and other information concerning the Corporation with the SEC. Shares of Texas
Regional Common Stock are traded on the NASDAQ National Market System.

     In May 1996, Texas Regional acquired, for cash, First State Bank & Trust
Co. of Mission, Texas, and its affiliate The Border Bank in Hidalgo, Texas.
These two acquisitions were funded in part by the public offering of 2,510,000
shares of Texas Regional Class A Voting Common stock, also completed in May
1996. First State Bank & Trust Co. had total assets of $353.4 million at the
time of the acquisition, and The Border Bank had total assets of $105.3 million
at that time.

     At September 30, 1997, Texas Regional and its subsidiaries had consolidated
total assets of $1.3 billion, loans (net of allowance for loan losses)
outstanding of $831.4 million and total deposits of $1.2 billion. Texas
Regional's primary activity is the commercial banking business of its
wholly-owned subsidiary, Texas State Bank, in McAllen, Harlingen, Weslaco,
Mission, Rio Grande City, Hidalgo, and surrounding areas of the Rio Grande
Valley, Texas. At the present time, the only non-banking subsidiary of Texas
Regional is TSB Securities, Inc., which expects to begin providing securities
transaction services in early 1998. Texas Regional may in the future establish
other non-banking subsidiaries to provide, or may itself provide, other services
permitted of bank holding companies which cannot be provided by banks.

     In October 1997, Texas Regional formed TRD, a Delaware corporation wholly
owned by Texas Regional. As of December 9, 1997, Texas Regional contributed all
of the capital stock of Texas State Bank, all of the capital stock of TSB
Securities, Inc., and certain other assets to TRD. TRD will, upon closing of the
Merger transaction, be the surviving corporation in the Merger with TB&T
Bancshares.

     Also in October 1997, Texas Regional entered into an Agreement and Plan of
Reorganization for the acquisition by merger of Brownsville Bancshares, Inc.
("Brownsville Bancshares"). As of September 30, 1997, Brownsville Bancshares
had total assets of $97.4 million, total loans (net of allowance for loan
losses) of $41.6 million, and total deposits of $84.4 million. Brownsville
Bancshares is expected to be merged with and into TRD as soon as applicable
conditions, including receipt of regulatory approval, are satisfied. Texas
Regional currently expects the Brownsville Bancshares transaction to be closed
contemporaneously with the closing of the TB&T Bancshares transaction, although
neither transaction is contingent upon the closing of the other. The
shareholders of Brownsville Bancshares will receive an aggregate of
approximately 947,164 shares of Texas Regional Common Stock in exchange for
their Brownsville Bancshares shares in connection with the merger transaction
(less fractional shares and shares attributable to shareholders exercising
dissenters' rights, if any) and holders of options to acquire Brownsville
Bancshares shares will receive an aggregate of approximately 37,836 shares of
Texas Regional Common Stock in exchange for the termination and cancellation of
their Brownsville Bancshares options (less any fractional shares). Brownsville
Bancshares' wholly owned subsidiary, BNB Bancshares, Inc. will also be merged
with and into TRD, and BNB Bancshares, Inc.'s subsidiary, Brownsville National
Bank, will be merged with and into Texas State

                                       9
<PAGE>
Bank. Brownsville National Bank operates from banking locations at 629 E.
Elizabeth Street, Brownsville, Texas, and at 3255 Boca Chica Boulevard,
Brownsville, Texas.

     In November 1997, Texas Regional entered into an agreement in principle for
the acquisition by merger of Raymondville Bancorp, Inc. ("Raymondville
Bancorp"). As of September 30, 1997, Raymondville Bancorp had total assets of
$60.4 million, total loans (net of allowance for loan losses) of $25.4 million,
and total deposits of $53.5 million. If the parties successfully negotiate a
mutually acceptable definitive agreement, Raymondville Bancorp will be merged
with a newly formed subsidiary of TRD as soon as applicable conditions,
including receipt of regulatory approval, are satisfied. As part of the
agreement in principle with Raymondville, the sole shareholder of Raymondville
has agreed to bear a portion of losses related to stolen or forged money orders
deposited into certain accounts held by Raymondville's wholly owned subsidiary,
Bank of Texas; however, there can be no assurance that the losses incurred on
those accounts and related return items will not exceed the limited amount of
the shareholder's reimbursement obligation and collateral provided by the
account holder. Texas Regional currently expects the Raymondville Bancorp
transaction to be closed contemporaneously with or as soon as practicable
following the closing of the TB&T Bancshares transaction, although neither
transaction is contingent upon the closing of the other. Under the agreement in
principle, which is not binding on either Texas Regional or Raymondville, upon
closing, the sole shareholder of Raymondville Bancorp would receive an aggregate
of $9,600,000 cash in exchange for his Raymondville Bancorp shares, an affiliate
of Raymondville Bancorp would receive $100,000 in consideration of a covenant
not to compete, and Raymondville Bancorp's wholly-owned subsidiary, Bank of
Texas of Raymondville, would be merged with and into Texas State Bank. Bank of
Texas operates from two banking locations, one each in Raymondville, Texas, and
at 2000 F.M. 802 in Brownsville, Texas.

     If the Merger with TB&T Bancshares, the merger with Brownsville Bancshares
and the merger with Raymondville are all consummated, as planned, Texas State
Bank will have a total of twenty-one full service banking locations in the Rio
Grande Valley of Texas.

     Texas Regional's wholly owned subsidiary, TRD, will be the surviving
corporation in the Merger with TB&T Bancshares and in the merger with
Brownsville Bancshares. The officers and directors of Texas Regional and TRD are
expected to be the officers and directors of Texas Regional and TRD,
respectively, following consummation of the merger transactions. Texas Regional
intends that Texas Bank & Trust will be merged with and into Texas State Bank
following the completion of the merger of Brownsville Bancshares with and into
TRD, subject to receipt of necessary regulatory approvals. As a result, the
separate existence of Texas Bank & Trust will cease and the main office of Texas
Bank & Trust will become a branch office of Texas State Bank. Texas Regional
expects that substantially all of the personnel of TB&T Bancshares and Texas
Bank & Trust will become employees of Texas State Bank following the closing of
the Merger.

TB&T BANCSHARES.

     TB&T Bancshares' operating subsidiary, Texas Bank & Trust, was chartered as
a Texas state bank in 1979, and opened for business in 1979. TB&T Bancshares,
through its ownership of Texas Bank & Trust, provides banking services for
customers in Brownsville, Texas and adjacent areas of the Rio Grande Valley. At
September 30, 1997 TB&T Bancshares had total assets of $43.8 million, loans
outstanding of $21.6 million (net of allowance for loan losses), deposits of
$39.4 million, and stockholders equity totaling $4.0 million. TB&T Bancshares is
located at 3201 Central Boulevard, Brownsville, Texas, and its telephone number
is (956) 787-9673.

FEDERAL INCOME TAX CONSEQUENCES.

     Neither Texas Regional, TB&T Bancshares, nor TRD has requested a ruling
from the Internal Revenue Service ("IRS") with regard to the proposed
transaction nor do they anticipate requesting such a ruling, nor has Texas
Regional or TB&T Bancshares requested an opinion of counsel concerning the
anticipated Federal income tax consequences of the proposed transaction.
However, management of Texas Regional

                                       10
<PAGE>
has consulted with the company's independent accountants concerning the tax
consequences of the transaction. As a result, management of Texas Regional
believes that if the transaction is consummated in accordance with the Agreement
and if certain technical requirements of the Federal income tax law are met, as
hereafter described, the Federal income tax consequences related to this
transaction should be as follows:

          (a)  the merger of TB&T Bancshares with and into TRD should constitute
     a reorganization within the meaning of Section 368(a)(1) by application of
     Section 368(a)(2)(D) of the Internal Revenue Code of 1986, as amended (the
     "Code");

          (b)  no gain or loss should be recognized to TB&T Bancshares or TRD
     upon consummation of the merger;

          (c)  no gain or loss should be recognized by the shareholders of TB&T
     Bancshares as a result of the receipt of Texas Regional Common Stock or
     upon distribution of shares of Texas Regional Common Stock from the escrow
     created pursuant to the Holdback Escrow Agreement, in respect of their TB&T
     Bancshares shares;

          (d)  the holding period of Texas Regional Common Stock received by the
     TB&T Bancshares shareholders should include the period during which the
     stock of TB&T Bancshares surrendered in exchange therefor has been held by
     them, provided the surrendered stock of TB&T Bancshares has been held as a
     capital asset in their hands.

     In addition to the above described consequences, any shareholder of TB&T
Bancshares who exercises his, her or its dissenters' rights of appraisal should
be treated for Federal income tax purposes as having received the resulting cash
proceeds as a distribution in redemption of his, her or its shares of TB&T
Bancshares stock, subject to the provisions and limitations of Section 302 of
the Code. In general, if such shareholder has all of his, her or its shares of
TB&T Bancshares stock so redeemed, and such shares of TB&T Bancshares stock have
been held as a capital asset by the dissenting shareholder, such shareholder
should recognize a capital gain or loss for Federal income tax purposes upon
receipt of the cash proceeds for the value of his, her to its shares.

     No information is provided with respect to the tax consequences, if any, to
the TB&T Bancshares shareholders under any local, state or foreign tax laws.

     Individual TB&T Bancshares shareholders are strongly urged to consult with
their respective tax advisers in regard to the foregoing summary and the
potential Federal income tax consequences of the proposed transaction to them.
In addition, any shareholder who is not a resident of Texas should consult with
such shareholder's own tax adviser for information concerning applicable state
and local tax consequences.

     For additional discussion of the Federal income tax consequences of the
transaction, see "Information About the Transaction -- Federal Income Tax
Consequences."

ACCOUNTING TREATMENT.

     Texas Regional anticipates accounting for the Merger under the
pooling-of-interests method of accounting for financial reporting and for all
other purposes, and the Company has received such assurances as its deems
appropriate that the Merger will qualify for pooling-of-interests accounting
treatment, including the receipt of a letter from KPMG Peat Marwick LLP, which
will be updated as of the effective time of the Merger, to the effect that the
Merger will qualify for pooling-of-interests accounting treatment. Nonetheless,
because the requirements for pooling-of-interests accounting are complex and
include matters outside of the control of the Company, there can be no certainty
that accounting for the transaction under that method of accounting will be
permitted. The pro forma information contained herein assumes that the
transaction will be accounted for under the pooling-of-interests method. See
"Information About the Transaction -- Accounting Treatment."

                                  RISK FACTORS

     ESCROW SHARES.  An aggregate of 49,958 shares of Texas Regional Common
Stock are to be placed in escrow at closing pursuant to the Holdback Escrow
Agreement. These shares will either be returned to Texas Regional or will be
distributed to the TB&T Bancshares shareholders, based upon the outcome of
certain contingencies, all of which are outside of the control of the TB&T
Bancshares shareholders. Frank D. Yturria is to be appointed as "Special
Agent" of the TB&T Bancshares shareholders under the Holdback Escrow Agreement
and will be entitled to act for all TB&T Bancshares shareholders in making
decisions relative to the escrow, including decisions related to whether to
accept certain compromises relative to the distribution of holdback escrow
shares.

     Under the Holdback Escrow Agreement, Texas Regional may require that shares
of escrow stock be returned to it in the event Texas Regional or Texas State
Bank incurs losses or damages arising directly or indirectly out of: the
activities of a named former employee of Texas Bank & Trust, identified in a
Special Report to the Board of Directors of TB&T; in connection with certain
pending litigation; in connection with a claim concerning an alleged deposit and
allegedly unauthorized transfers and withdrawals from an account at Texas Bank &
Trust; or in connection with certain missing certificates of deposit. The number
of shares deposited into escrow pursuant to the Holdback Escrow Agreement has
been fixed pursuant to the Agreement; however, there can be no certainty that
the amount of losses to Texas Regional and Texas State Bank will not exceed the
amount retained as holdback shares.

     Texas Regional and the TB&T Bancshares shareholders share in the losses and
damages based on a formula set forth in the Holdback Escrow Agreement, and the
number of escrow shares to be returned to Texas Regional is based on the amount
of Texas Regional's share of losses and damages, divided by $30.025. Only
dividends accruing with respect to shares of escrow stock ultimately distributed
to TB&T Bancshares shareholders are to be distributed to TB&T Bancshares
shareholders. Any dividends related to shares returned to Texas Regional will be
returned to Texas Regional. The Holdback Escrow Agreement provides for a partial
distribution of escrow shares on the second anniversary of the execution of the
Holdback Escrow Agreement, with any shares attributable to anticipated losses
and damages to Texas Regional related to any then-pending claims to continue to
be held until resolution of the claims. See "Information About the
Transaction -- Holdback Escrow."

     CONTROL.  TB&T Bancshares shareholders currently control TB&T Bancshares
through their ability to elect the Board of Directors of TB&T Bancshares and
vote on various matters affecting TB&T Bancshares. The Merger will transfer
control of TB&T Bancshares from TB&T Bancshares' shareholders to Texas Regional.
As of the effective time of the Merger, the shareholders of TB&T Bancshares will
become shareholders of Texas Regional, a much larger organization, and the
former shareholders of TB&T Bancshares will no longer have the ability to
control or influence the management policies or TB&T Bancshares' operations. As
shareholders of Texas Regional, their ability to influence the management
policies of Texas Regional will be limited due to the fact that they will hold a
relatively small percentage of the voting stock of Texas Regional.

     Following consummation of the Merger, (i) all lending at the facilities
formerly operated by Texas Bank & Trust will be conducted pursuant to Texas
State Bank's policies and under the supervision of Texas State Bank's chief
lending officer; (ii) investments in securities will be managed by the
investment division of Texas State Bank in accordance with Texas State Bank's
investment policies; and (iii) all data processing will be performed by Texas
State Bank's data processing center. In general, the policies and procedures for
all banking locations, including the banking location formerly operated as Texas
Bank & Trust, will be Texas State Bank's policies and procedures.

     PROFITABILITY LINKED TO BANKING ACTIVITIES.  Because Texas Regional's
non-banking activities represent a very small portion of its business, the
profitability of Texas Regional will be directly attributable to the success of
its subsidiary, Texas State Bank. Texas Regional's banking activities compete
with other banking institutions on the basis of service, convenience and, to
some extent, price. Due in part to both regulatory changes and consumer demands,
banks have experienced increased competition from other financial entities
offering similar products. Competition from both bank and non-bank organizations
is expected to continue.

                                       12
<PAGE>
     Texas Regional will rely on the profitability of Texas State Bank and
dividends received from Texas State Bank for payment of its operating expenses
and satisfaction of its obligations. As is the case with other similarly
situated financial institutions, the profitability of Texas State Bank, and
therefore of Texas Regional, will be subject to the fluctuating cost and
availability of money, changes in the prime lending rate, changes in economic
conditions in general and, because of the location of all of the branch
facilities, changes in economic conditions in the Texas Rio Grande Valley in
particular. In addition, Texas State Bank is subject to capital adequacy
guidelines promulgated from time to time by applicable regulatory authorities.

     GEOGRAPHIC CONCENTRATION.  Texas Regional's profitability is dependent on
the profitability of its subsidiary bank, Texas State Bank, which operates only
in the Rio Grande Valley of Texas. In addition to adverse changes in general
conditions in the United States, unfavorable changes in economic conditions
affecting the Rio Grande Valley, such as adverse effects of weather on
agricultural production, adverse changes in United States-Mexico relations, and
substantial Mexican peso devaluations, may have a significant adverse impact on
operations of the Company.

     COMPETITION.  The banking industry in the Rio Grande Valley is highly
competitive. Texas State Bank and Texas Bank & Trust compete as financial
intermediaries with other commercial banks, savings and loan associations,
credit unions, mortgage banking companies, securities brokerage companies,
consumer and commercial finance companies, insurance companies and money market
mutual funds operating in Texas and elsewhere. Many of the competitors have
substantially greater resources and lending limits than Texas State Bank has or
will have following the Merger, and in some cases these competitors offer
services that Texas State Bank does not currently provide. In addition,
non-depository institution competitors are generally not subject to the
extensive regulation applicable to Texas State Bank.

     REGULATORY RESTRICTIONS AND REQUIREMENTS.  Texas Regional and Texas State
Bank are subject to extensive government regulation and supervision under
various state and federal laws, rules and regulations, including rules and
regulations promulgated by the Federal Reserve Board (the "FRB") and the Texas
Banking Department (the "Banking Department"). These laws and regulations are
designed primarily to protect the Bank Insurance Fund of the Federal Deposit
Insurance Corporation (the "FDIC"), depositors and borrowers, and to further
certain social policies and, consequently, may impose limitations on Texas
Regional that may not be in the best interests of the Company and its
shareholders.

     Texas State Bank is subject to regulation by the Texas Department of
Banking, and is subject to regulation by its "primary federal regulator," the
Federal Reserve Board, since Texas State Bank is a Federal Reserve member bank.
For Texas Bank & Trust, the primary federal regulator is the Federal Deposit
Insurance Corporation, since Texas Bank & Trust is not a member of the Federal
Reserve System. If the transaction is consummated, the effect will be that Texas
Bank & Trust's business as merged into Texas State Bank will be subject to
regulation by the Texas Department of Banking, to which Texas Bank & Trust is
presently subject, and the Federal Reserve Board, to which it is not presently
subject.

     RELIANCE ON CHIEF EXECUTIVE OFFICER.  Texas Regional has experienced
substantial growth in assets and deposits during the past, particularly since
Glen E. Roney became Chairman of the Board and Chief Executive Officer of the
company in 1985. Although Mr. Roney is a substantial shareholder of the Company
and is the beneficiary of a deferred compensation arrangement with the Company
that generally requires continued service for vesting, the Company does not have
an employment agreement with Mr. Roney and the loss of the services of Mr. Roney
could have a material adverse effect on Texas Regional's business and prospects.

                       INFORMATION ABOUT THE TRANSACTION

     The following information relating to the Merger is not intended to be a
complete description of all information relating to the Merger and is qualified
in its entirety by reference to more detailed information contained elsewhere in
this Prospectus/Proxy Statement, including the annexes hereto and the documents
referred to herein or incorporated herein by reference. A copy of the Agreement
is included herein as Annex A, and is incorporated herein by this reference for
all purposes. The Holdback Escrow Agreement is, in turn, attached to the
Agreement as Schedule 1.7. All shareholders of TB&T Bancshares are urged to read
the Agreement and the Holdback Escrow Agreement, in their entirety.

                                       16

TERMS OF THE AGREEMENT.

     The Agreement provides that TB&T Bancshares will be merged with and into
TRD, and the outstanding capital stock of TB&T Bancshares will be converted into
and exchanged for the right to receive shares of Texas Regional Class A Voting
Common stock as herein described. Each TB&T Bancshares share shall be converted
into and exchanged for the right to receive at closing 0.1522126 of a share of
Texas Regional Common Stock. In addition, 0.0294605 of a share of Texas Regional
Common Stock will be deposited into escrow and held and distributed pursuant to
the Holdback Escrow Agreement. No fractional shares shall be issued, and any
individual shareholder who would otherwise be entitled to a fractional share of
Texas Regional Common Stock either as a result of the issuance of shares at
closing or the issuance of shares pursuant to the Holdback Escrow Agreement or
otherwise shall receive cash in lieu of such fractional share, equal to the
product of $30.025 multiplied by such fractional share.

     On the effective date of the Merger, TB&T Bancshares will be merged with
and into TRD, and all of the capital stock of Texas Bank & Trust will then be
owned by Texas Regional. Immediately following consummation of the Merger, Texas
Bank & Trust will be merged with and into Texas State Bank, and the banking
location now operated as Texas Bank & Trust will become a branch facility of
Texas State Bank.

     In the event the merger is approved and no holders of TB&T Bancshares
capital stock elect to exercise dissenters' rights of appraisal, TB&T Bancshares
shareholders will receive an aggregate of approximately 258,118 shares of Texas
Regional Common Stock at closing, and an aggregate of approximately 49,958
shares of Texas Regional Common Stock will be deposited into escrow to be held
pursuant to the Holdback Escrow Agreement. Excluding the effect of any shares
issued in connection with the merger with Brownsville Bancshares, present TB&T
Bancshares shareholders will, immediately following consummation of the merger,
own approximately 1.9% of the total outstanding Texas Regional Common Stock as a
result of their exchange of TB&T Bancshares stock, and approximately 0.4% of the
total outstanding Texas Regional Common Stock will be deposited into and held
pursuant to the Holdback Escrow Agreement.

     The terms of the Agreement, including the exchange ratio and the number of
shares to be deposited into escrow pursuant to the Holdback Escrow Agreement,
are the result of negotiations between the Board of Directors and principal
executive officers of Texas Regional and the Board of Directors and principal
executive officers of TB&T Bancshares, each of whom considered many factors,
including the earnings and dividends and related trends of Texas Regional and
TB&T Bancshares, their book and estimated market values of assets, their
deposits and other liabilities, the nature and capabilities of management, their
earnings and growth capacities based on the nature of the markets in which they
operate and their projected future values and prospects as separate companies.

     The TB&T Bancshares Board of Directors has reviewed and approved the
Merger, has authorized the preparation of this Prospectus/Proxy Statement and
has recommended approval by the shareholders. The Merger must be approved by the
affirmative vote of the holders of two-thirds of the outstanding capital stock
of TB&T Bancshares. Each member of the Board of Directors of TB&T Bancshares,
and certain related parties, have joined into the execution of the Agreement, to
evidence their agreement to vote for the transaction at the special meeting of
the TB&T Bancshares shareholders. The aggregate number of TB&T Bancshares shares
held by all such shareholders is 1,388,104, representing 81.9% of the issued and
outstanding capital stock of TB&T Bancshares. Since the aggregate number of
shares held by shareholders joining into this Agreement and committing to vote
their shares in favor of the Merger at the special meeting of the TB&T
Bancshares shareholders is in excess of two-thirds of the outstanding capital
stock of TB&T Bancshares, the transaction is expected to be approved by the
shareholders. No shareholder has notified TB&T Bancshares or Texas Regional that
such shareholder intends to oppose the motion to approve the Merger at the
Meeting.

     Texas Regional, as the sole shareholder of TRD, has already approved the
Merger and authorized consummation of the transactions herein described, subject
to receipt of regulatory approvals and satisfaction of other conditions
described in the Agreement.

                                       17
<PAGE>
     It is anticipated that the Merger will be effective as soon as practicable
following the receipt of all necessary regulatory approvals and the satisfaction
of all conditions to the consummation of the Merger. At the effective time of
the Merger, by operation of law, holders of TB&T Bancshares Common Stock (other
than those shareholders who perfect their dissenters' rights of appraisal) will
become owners of Texas Regional Common Stock and will no longer be owners of
TB&T Bancshares capital stock. After the effective time of the Merger, all
certificates for TB&T Bancshares capital stock will represent the right to
receive Texas Regional Common Stock pursuant to the Agreement, but otherwise
will be null and void after such date.

HOLDBACK ESCROW.

     The Agreement provides that an aggregate of 49,958 shares of Texas Regional
Common Stock will be deposited into escrow at the time of closing and will be
held pursuant to the terms of a Holdback Escrow Agreement to be executed at the
time of closing in the form attached to the Agreement. These shares will either
be returned to Texas Regional or will be distributed to the TB&T Bancshares
shareholders, based upon the outcome of certain contingencies. Frank D. Yturria
is to be appointed as "Special Agent" of the TB&T Bancshares shareholders
under the Holdback Escrow Agreement and will be entitled to act for all TB&T
Bancshares shareholders in making decisions relative to the escrow, including
decisions related to whether to accept certain compromises relative to the
distribution of holdback escrow shares.

     Under the Holdback Escrow Agreement, Texas Regional may require that shares
of escrow stock be returned to it in the event Texas Regional or Texas State
Bank incurs losses or damages arising directly or indirectly: (i) out of the
activities of a named former employee of Texas Bank & Trust, identified in a
Special Report to the Board of Directors of TB&T; (ii) in connection with
certain pending litigation; (iii) in connection with a claim concerning an
alleged deposit and allegedly unauthorized transfers and withdrawals from an
account at Texas Bank & Trust; or (iv) in connection with certain missing
certificates of deposit.

     Texas Regional and the TB&T Bancshares shareholders share in the losses and
damages based on a formula set forth in the Holdback Escrow Agreement, and the
number of escrow shares to be returned to Texas Regional is based on the amount
of Texas Regional's share of losses and damages, divided by $30.025. Only
dividends accruing with respect to shares of escrow stock ultimately distributed
to TB&T Bancshares shareholders are to be distributed to TB&T Bancshares
shareholders. Any dividends related to shares returned to Texas Regional will
likewise be returned to Texas Regional. The Holdback Escrow Agreement provides
for a partial distribution of escrow shares on the second anniversary of the
execution of the Holdback Escrow Agreement, with any shares attributable to
anticipated losses and damages to Texas Regional related to any then-pending
claims to continue to be held until resolution of the claims. See "Information
About the Transaction -- Terms of the Agreement."

STOCK CERTIFICATES AND FRACTIONAL SHARES.

     It is anticipated by Texas Regional that, promptly after the approval of
the Merger by the TB&T Bancshares shareholders and by applicable regulatory
authorities, transmittal forms will be sent to each shareholder of TB&T
Bancshares for use in forwarding his, her or its certificates for shares of
capital stock of TB&T Bancshares to Texas Regional. For each share surrendered
Texas Regional will deliver to the former TB&T Bancshares shareholder 0.1522126
of a share of Texas Regional Common Stock. In addition, distributions will be
made out of the escrow account created pursuant to the Holdback Escrow Agreement
only to shareholders who have delivered their certificates for shares of capital
stock of TB&T Bancshares to Texas Regional. No fractional shares shall be issued
in respect of a shareholder's shares, either as part of the initial distribution
of shares or out of the escrow account, and any shareholder who would otherwise
be entitled to a fractional share of Texas Regional Common Stock shall receive
cash in lieu of such fractional shares, equal to the product of $30.025
multiplied by such fractional share.

     Texas Regional share certificates which are to be delivered at the time of
closing shall be delivered to shareholders who have theretofore surrendered
their TB&T Bancshares share certificates, either (i) by mailing the same to the
shareholder at the shareholder's address as stated in the stock transfer records
of TB&T Bancshares, or (ii) by such other arrangements as may be mutually agreed
by and between such

                                       18
<PAGE>
former TB&T Bancshares shareholder and Texas Regional. Any Texas Regional share
certificate deliverable to a shareholder which would otherwise have been
delivered at closing, but which is not delivered at closing because such
shareholder did not surrender his, her or its TB&T Bancshares certificates until
after the effective time of the Merger, shall be mailed to the former TB&T
Bancshares shareholder within a reasonable period of time following receipt of
the shareholder's TB&T Bancshares share certificate. The stock transfer records
of TB&T Bancshares shall for all purposes be closed as of the effective time of
the Merger and no transfer of record of any of the shares of TB&T Bancshares
capital stock shall take place thereafter.

     Until certificates representing capital stock of TB&T Bancshares are
surrendered, Texas Regional will set aside shares for making the deliveries, but
any dividends or other amounts payable to shareholders who surrender their share
certificates after the effective time of the Merger will not be payable until
surrender of the shareholder's share certificate, nor shall any amounts bear
interest attributable to periods either before or after the effective time of
the Merger.

     After the effective date of the Merger, the TB&T Bancshares share
certificates that theretofore represented ownership of the capital stock of TB&T
Bancshares shall be converted automatically into the right to receive shares of
Texas Regional Common Stock as herein described. No dividends on TB&T Bancshares
capital stock shall accrue with respect to such shares as are held by any
shareholder, after the effective date of the merger.

     SHAREHOLDERS OF TB&T BANCSHARES SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
TRANSMITTAL MATERIALS ARE RECEIVED.

REASONS FOR THE MERGER.

     The Board of Directors of TB&T Bancshares has approved the Agreement as
being in the best interests of TB&T Bancshares and its shareholders, and the
Board of Directors of Texas Regional has also approved the Agreement as being in
the best interests of Texas Regional and its shareholders. If the transactions
contemplated by the Agreement are consummated, TB&T Bancshares will be merged
with and into TRD, its separate existence will cease, and present TB&T
Bancshares shareholders will become shareholders of Texas Regional. The Boards
of Directors of TB&T Bancshares and Texas Regional believe that the merger of
TB&T Bancshares with a subsidiary of Texas Regional will offer a number of
advantages.

     In evaluating the Texas Regional offer, TB&T Bancshares' Board of Directors
considered other transactions in the Rio Grande Valley area of Texas, as well as
transactions in other areas of Texas and elsewhere.

     Among the factors considered by the Board of Directors of TB&T Bancshares
was the limited market for TB&T Bancshares' stock. The outstanding common stock
of TB&T Bancshares is not widely held and there is not an active trading market.
By contrast, Texas Regional's common shares are listed on the NASDAQ National
Market System and there is an active market for its stock.

     The Board of Directors of TB&T Bancshares also considered the competitive
market in which TB&T Bancshares operates. The banking industry in general and in
the Rio Grande Valley of Texas in particular is consolidating. TB&T Bancshares
competes with larger and more highly capitalized institutions. Its ability to
offer different products, compete for qualified personnel and develop a network
of branches would have required additional capital and possibly limited future
dividends. Furthermore, developing such an organization would require several
years. By merging with Texas Regional, TB&T Bancshares' shareholders would
become shareholders of an organization which is in a stronger competitive
position but which is nonetheless headquartered in the same area.

     For the reasons set forth above, the TB&T Bancshares Board of Directors
unanimously approved the Merger and recommends approval of the transaction by
the TB&T Bancshares shareholders.

     Texas Regional has long considered expansion opportunities in its market
area, and in Brownsville in particular, in order to expand to a more economical
size, to provide more effective customer service for its existing customers and
to expand the customer base for the company's services. Acquiring TB&T

                                       19
<PAGE>
Bancshares will result in economies of scale and increase the markets served by
Texas Regional's subsidiary, Texas State Bank. It will also assist Texas State
Bank in providing the management and organizational flexibility needed to expand
in the Brownsville market.

     Following arm's length negotiations between representatives of Texas
Regional and TB&T Bancshares, Texas Regional and TB&T Bancshares entered into
the Agreement on October 15, 1997. The aggregate amount to be paid to holders of
TB&T Bancshares shares and to be deposited into escrow resulted from
negotiations which considered the historical earnings and dividends of Texas
Regional and TB&T Bancshares, the earnings potential and deposit base of TB&T
Bancshares, potential growth in the Brownsville market, TB&T Bancshares' asset
quality and the effect of the Merger on the shareholders, customers and
employees of Texas Regional and TB&T Bancshares.

     Subject to satisfaction of certain conditions contained in the Agreement,
TB&T Bancshares Board of Directors believes the Merger to be fair and in the
best interests of TB&T Bancshares and its shareholders. TB&T BANCSHARES BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE TB&T BANCSHARES SHAREHOLDERS VOTE FOR
APPROVAL OF THE MERGER. TB&T Bancshares has authorized consummation of the
Merger, subject to approval of the TB&T Bancshares shareholders, federal and
state bank regulators and the satisfaction of certain other conditions. See
"Information About the Transaction -- Terms of the Agreement" and
"Information About the Transaction -- Other Terms and Conditions."

OPERATIONS FOLLOWING THE MERGER.

     Texas Regional and TB&T Bancshares intend that following the Merger of TB&T
Bancshares with and into TRD, Texas Bank & Trust will be merged with and into
Texas State Bank. Following the subsequent merger of Texas Bank & Trust with and
into Texas State Bank, the separate existence of Texas Bank & Trust will cease,
and Texas State Bank will continue as the surviving entity.

OTHER TERMS AND CONDITIONS.

     The Agreement contains a number of terms, conditions, representations and
covenants which must be satisfied as of the effective time of the Merger
including, but not limited to, the following:

          (1)  If the closing shall not have been accomplished on or before
     March 1, 1998, the Agreement shall, at the election of either TB&T
     Bancshares or Texas Regional by written notice, be terminated and be of no
     further force or affect.

          (2)  The transaction shall have been approved by the requisite vote of
     the shareholders of TB&T Bancshares at a duly called meeting of the
     shareholders.

          (3)  The representations and warranties of TB&T Bancshares in the
     Agreement shall have been true when made, and except for changes
     contemplated by the Agreement, shall be true at the effective time of the
     Merger.

          (4)  Shareholders holding an aggregate of not greater than 2% of the
     issued and outstanding shares of TB&T Bancshares shall have exercised
     dissenters' rights of appraisal with respect to the transaction.

          (5)  Texas Regional shall have received approval of the transactions
     contemplated by the Agreement including both the merger of TB&T Bancshares
     with and into TRD, and the merger of Texas Bank & Trust with and into Texas
     State Bank, from all necessary governmental agencies and authorities,
     including the Texas Banking Department and the Federal Reserve Board, and
     such approvals and transactions shall not have been contested by any
     Federal or State governmental authority nor by any third party.

          (6)  There shall not be any litigation, investigation, inquiry or
     proceeding pending or threatened in or by any court or governmental agency
     or authority which might result in an action to restrain, enjoin or
     prohibit consummation of the transaction or which might result in
     divestiture, rescission or damages in connection with such transaction or
     involving any of the assets, properties, business or

                                       20
<PAGE>
     operations of TB&T Bancshares or Texas Bank & Trust which might result in
     any material adverse change in the financial condition, results of
     operation, business or prospects of TB&T Bancshares or its subsidiary.

          (7)  Texas Regional shall have been delivered an opinion of TB&T
     Bancshares' counsel as required by the Agreement.

          (8)  Texas Regional shall be entitled to terminate the transaction if
     the results of its due diligence review are not satisfactory in all
     respects to Texas Regional and no material adverse change shall have
     occurred in the condition, financial position or business prospects of TB&T
     Bancshares or its subsidiary.

          (9)  Texas Regional shall have received all consents, approvals and
     estoppel certificates and other assurances as it may deem reasonably
     necessary.

          (10)  The net worth of TB&T Bancshares, calculated in accordance with
     applicable regulatory requirements, shall be not less than the sum of
     $3,980,000 increased by $25,000 per month for each month elapsed during the
     period from September 30, 1997 until the date of closing.

          (11)  TB&T Bancshares shall be satisfied that no material adverse
     change shall have occurred in the condition, financial position or business
     prospects of Texas Regional or Texas State Bank.

          (12)  Texas Regional shall not have been presented with evidence
     indicating that special claims (as that term is used in the Holdback Escrow
     Agreement) are likely to result in uninsured losses to Texas State Bank, as
     the successor in interest to Texas Bank & Trust (without regard to any
     return and cancellation of shares held pursuant to the Holdback Escrow
     Agreement) in excess of $2,500,000.

Some of the foregoing are conditions to the obligation of Texas Regional to
close the Merger transaction, some are conditions to the obligation of TB&T
Bancshares to close and others are conditions to both parties' obligation to
close. Any condition to the consummation of the Merger may be waived by the
party to the Agreement entitled to the benefit of such condition.

     One of the conditions to TB&T Bancshares' obligation to close the
transaction is the receipt of an opinion as to the fairness of the transaction
to TB&T Bancshares and its shareholders. Management of TB&T Bancshares has
indicated to Texas Regional that TB&T Bancshares has waived that condition.

JOINDER BY CERTAIN SHAREHOLDERS.

     Certain shareholders of TB&T Bancshares have joined into the execution of
the Agreement to evidence their consent to and approval of the transaction
described in the Agreement. Each of those shareholders, who in the aggregate
hold 1,388,104 shares, or 81.9% of the total outstanding shares of TB&T
Bancshares, have represented to Texas Regional that the TB&T Bancshares common
shareholders are the only persons entitled to consent to and vote on the Merger
transaction, that such shareholder owns the number of shares of TB&T Bancshares
indicated below is his, her or its name in the Agreement, and that the
shareholder has full power and authority to enter into and perform the
Agreement. Each shareholder further agreed to recommend the transaction to other
shareholders and to vote to approve the transaction at the special meeting of
the TB&T Bancshares shareholders called to consider the Merger transaction.

     Each of those shareholders is an officer, director and/or holder of 5% or
more of the outstanding capital stock of TB&T Bancshares. The named shareholders
have agreed not to sell, pledge, transfer or otherwise dispose of any shares of
TB&T Bancshares stock within 30 days prior to the effective time of the Merger,
and have agreed that, until publication of financial results covering at least
30 days of post-merger combined operations of TB&T Bancshares and Texas
Regional, such shareholders will not sell, pledge, transfer or otherwise dispose
of any shares of Texas Regional Common Stock acquired in the Merger, without
first obtaining the consent of Texas Regional. This group of shareholders has
further agreed not to sell, pledge, transfer or otherwise dispose of any shares
of Texas Regional stock acquired in the Merger except in a manner that is
consistent with any additional requirements imposed upon Texas Regional to
permit Texas Regional to account for the Merger as a pooling of interests. Each
shareholder who is a

                                       21
<PAGE>
director or executive officer of TB&T Bancshares has further acknowledged and
agreed that such shareholder will be subject to Rule 145 promulgated by the
Securities and Exchange Commission and has agreed not to transfer any Texas
Regional stock received by such shareholder in the Merger, except in compliance
with applicable provisions of the Securities Act of 1933, the Securities and
Exchange Act of 1934 and applicable rules and regulations promulgated by the
Securities and Exchange Commission thereunder.

BUSINESS PENDING CONSUMMATION OF THE MERGER.

     The Agreement imposes certain limitations on the conduct of TB&T
Bancshares' business pending consummation of the Merger. Among other things,
TB&T Bancshares must conduct its business consistent with prudent banking
practices in the same manner as conducted prior to the execution of the
Agreement. TB&T Bancshares has also agreed not to make loans in amounts in
excess of certain thresholds without the approval of Texas Regional and has
agreed not to acquire investment securities unless they meet certain parameters.
The Agreement also requires that employment agreements and certain kinds of
employee benefit plans, be terminated at or prior to the effective time of the
Merger. See Annex A.

AMENDMENT OR TERMINATION OF THE AGREEMENT.

     The Agreement may be amended at any time, before or after the meeting of
the TB&T Bancshares shareholders, by an instrument in writing duly executed by
all parties to the Agreement. In addition, the Agreement may be terminated, at
the election of either Texas Regional or TB&T Bancshares, if the Merger has not
become effective on or before March 1, 1998.

DISSENTERS' RIGHTS.

     By following the specific procedures set forth in the Texas Business
Corporation Act, TB&T Bancshares' shareholders have a statutory right to dissent
from the Merger. If the Merger is approved and consummated, any TB&T Bancshares
shareholder who properly perfects his, her or its dissenters' rights will be
entitled, upon consummation of the Merger, to receive an amount of cash equal to
the fair value of his, her or its shares of TB&T Bancshares common stock rather
than receiving the consideration set forth in the Agreement. The following
summary is not a complete statement of statutory dissenters' rights of
appraisal, and such summary is qualified by reference to the applicable
provisions of the Texas Business Corporation Act, which is reproduced in full in
Annex B to this Prospectus/Proxy Statement. A shareholder must complete each
step in the precise order prescribed by the statute to perfect his, her or its
dissenters' rights of appraisal.

     Any shareholder who desires to dissent from the Merger shall file a written
objection to the Merger with TB&T Bancshares prior to the meeting at which the
vote on the Merger shall be taken, stating that the shareholder will exercise
his, her or its right to dissent if the Merger is effective and giving the
shareholder's address to which notice thereof shall be sent. A vote against the
Merger is not sufficient to perfect a shareholder's dissenters' rights of
appraisal. If the Merger is effected, each shareholder who sent notice to TB&T
Bancshares as described above and who did not vote in favor of the Merger will
be deemed to have dissented from the Merger (herein sometimes referred to as a
"Dissenting Shareholder"). Failure to vote against the Merger will not
constitute a waiver of the dissenters' rights of appraisal; on the other hand, a
vote in favor of the Merger will constitute such a waiver.

     TRD, as the survivor in the Merger transaction, will be liable for
discharging the rights of Dissenting Shareholders and shall, within 10 days of
the effective time of the Merger, notify the Dissenting Shareholders in writing
that the Merger has been effected. Each Dissenting Shareholder so notified must,
within 10 days of the delivery of mailing of such notice, make a written demand
on TRD at Kerria Plaza, Suite 301, 3700 North 10th Street, McAllen, Texas 78501,
for payment of the fair value of the Dissenting Shareholder's shares as
estimated by the Dissenting Shareholder. Such demand shall state the number and
class of shares owned by the Dissenting Shareholder. The fair value of the
shares shall be the value thereof as of the date immediately preceding the date
of the shareholder meeting at which the Merger was approved, excluding any
appreciation or depreciation in anticipation of the Merger. Dissenting
Shareholders

                                       22
<PAGE>
who failed to make a written demand within the 10 day period will be bound by
the Merger and lose their rights to dissent. Within 20 days after making a
demand, the Dissenting Shareholder shall submit certificates representing his,
her or its shares of TB&T Bancshares common stock to Texas Regional for notation
thereon that such demand has been made. Dissenting Shareholders who fail to
submit their certificates within such 20 day period will be bound by the Merger
and lose their rights to dissent.

     Within 20 days after receipt of a Dissenting Shareholder's demand letter as
described above, TRD shall deliver or mail to the Dissenting Shareholder written
notice (i) stating that TRD accepts the amount claimed in the demand letter and
agrees to pay that amount within 90 days after the effective time of the Merger
upon surrender of the relevant certificates of TB&T Bancshares common stock duly
endorsed by the Dissenting Shareholder, or (ii) containing TRD's written
estimate of the fair value of the shares of TB&T Bancshares common stock
together with an offer to pay such amount within 90 days after the effective
time of the Merger if TRD receives notice, within 60 days after the effective
time of the Merger, stating that the Dissenting Shareholder agrees to accept
that amount and surrenders the relevant certificates of TB&T Bancshares common
stock duly endorsed by the Dissenting Shareholder. In either case, the
Dissenting Shareholder shall cease to have any ownership interest in TB&T
Bancshares or Texas Regional following payment of the agreed value.

     If the Dissenting Shareholder and Texas Regional cannot agree on the fair
value of the shares within 60 days after the effective time of the Merger, the
Dissenting Shareholder or TRD may, within 60 days of the expiration of the
initial 60 day period, file a petition in any court of competent jurisdiction
requesting a finding and determination of the fair value of the Dissenting
Shareholder's shares. If no petition is filed within the appropriate time
period, then all Dissenting Shareholders who have not reached an agreement with
TRD on the value of their shares shall be bound by the Merger and lose their
rights to dissent. After a hearing concerning the petition, the court shall
determine which Dissenting Shareholders have complied with the provisions of the
Texas Business Corporation Act and have become entitled to the valuation of, and
payment for, their TB&T Bancshares shares, and shall appoint one or more
qualified appraisers to determine the value of the TB&T Bancshares shares in
question. The appraiser shall determine such value and file a report with the
court. The court shall then in its judgment determine the fair value of the
shares of TB&T Bancshares common stock, which judgment shall be binding on TRD
and on all Dissenting Shareholders receiving notice of the hearing. The court
shall direct TRD to pay such amount, together with interest thereon, beginning
91 days after the effective time of the Merger to the date of judgment, to the
Dissenting Shareholders entitled thereto. The judgment shall be payable upon the
surrender to TRD of certificates representing shares of TB&T Bancshares common
stock duly endorsed by the Dissenting Shareholders. Upon payment of the
judgment, the Dissenting Shareholders shall cease to have any interest in TB&T
Bancshares, Texas Regional, TRD or the TB&T Bancshares common stock. All court
costs and fees of the appraiser shall be allotted between the parties in a
manner that the court determines is fair.

     Any Dissenting Shareholder who has made a written demand on TRD for payment
of the fair value of his, her or its TB&T Bancshares common stock shall not
thereafter be entitled to vote or exercise any other rights as a shareholder
except the statutory right of appraisal as described herein and the right to
maintain an appropriate action to obtain relief on the ground that the Merger
would be or was fraudulent. In the absence of fraud in the transaction, a
Dissenting Shareholder's statutory right to appraisal is the exclusive remedy
for the recovery of the value of his, her or its shares or money damages to the
shareholder with respect to the Merger.

     Any Dissenting Shareholder who has made a written demand on TRD for payment
of the fair value of his, her or its TB&T Bancshares common stock may withdraw
such demand at any time before payment for his, her or its shares or before a
petition has been filed with an appropriate court for determination of the fair
value of such shares. If a Dissenting Shareholder withdraws his, her or its
demand or if the Dissenting Shareholder is otherwise unsuccessful in asserting
his, her or its dissenters' rights of appraisal, such Dissenting Shareholder
shall be bound by the Merger and such shareholder's status as a shareholder
shall be restored without prejudice to any corporate proceedings, dividends or
distributions which may have occurred during the interim. See Annex B.

     It is a condition to Texas Regional's obligations under the Agreement that
not more than 2% of the outstanding shares of TB&T Bancshares common stock shall
have demanded or be entitled to demand payment of the fair value of the shares
as Dissenting Shareholders. If such condition is not met, Texas Regional will be
entitled to terminate the Agreement. See "Information About the
Transaction -- Other Terms and Conditions." See also "Information About the
Transaction -- Federal Income Tax Consequences" for a description of the tax
consequences of exercising dissenters' rights.

FEDERAL INCOME TAX CONSEQUENCES.

     In the opinion of KPMG Peat Marwick LLP ("KPMG"), if consummated in
accordance with the Agreement, the Merger will qualify as a "reorganization"
within the meaning of Section 368(a) of the Code. A copy of KPMG's opinion is
included with this Prospectus/Proxy Statement as Annex C. The opinion of KPMG is
not binding on the Internal Revenue Service or the courts.

     KPMG has relied upon certain assumptions and representations in issuing its
opinion, including the following:

          (1)  The managements of Texas Regional and TB&T Bancshares are not
     aware of any plan or intention on the part of TB&T Bancshares shareholders
     to sell a number of shares of Texas Regional Common Stock that will reduce
     such shareholders' ownership to a number of shares having, in the
     aggregate, a value of less than 50% of the fair market value of TB&T
     Bancshares stock outstanding as of the Effective Date.

          (2)  TRD will acquire substantially all the assets of TB&T Bancshares.

          (3)  Following the transaction, TRD will not issue additional shares
     of its stock that would result in Texas Regional losing control of TRD.

          (4)  Texas Regional, TRD and Texas State Bank have no plan or
     intention to sell or otherwise dispose of any of the assets to be received
     from TB&T Bancshares and Texas Bank & Trust, except for dispositions made
     in the ordinary course of business.

     In KPMG's opinion, the following federal income tax consequences to TB&T
Bancshares shareholders will result from a qualification of the Merger as a
reorganization under Section 368(a) of the Code:

          (1)  A TB&T Bancshares shareholder will not recognize any gain or loss
     upon the exchange of his, her or its TB&T Bancshares common stock solely
     for Texas Regional Common Stock.

          (2)  The aggregate tax basis of Texas Regional Common Stock received
     by a TB&T Bancshares shareholder in the Merger will be same as the
     aggregate basis of the TB&T Bancshares common stock surrendered in exchange
     therefor. For purposes of allocating this aggregate basis to individual
     shares of Texas Regional Common Stock received, the IRS position is that
     each separate block of stock surrendered shall be treated separately. Under
     this rule, for example, if a TB&T Bancshares shareholder surrenders two
     blocks of TB&T Bancshares common stock in the Merger, having an adjusted
     basis of $1.00 per share for the first block and $2.00 per share for the
     second block, the Texas Regional Common Stock which he, she or it receives
     in exchange for each share of TB&T Bancshares common stock in the first
     block will have a basis of $1.00, and the Texas Regional Common Stock which
     he, she or it receives in exchange for each share of TB&T Bancshares common
     stock in the second block will have a basis of $2.00.

          (3)  The holding period of Texas Regional Common Stock to be received
     by each TB&T Bancshares shareholder will include the period during which
     the shareholder held the TB&T Bancshares common stock surrendered in
     exchange therefor, provided that the TB&T Bancshares common stock is held
     as a capital asset on the date of the exchange.

          (4)  The payment of cash in lieu of fractional shares of Texas
     Regional Common Stock will be treated as if the fractional shares were
     distributed as part of the exchange and then redeemed by Texas Regional.
     Such cash payment will be treated as having been received as a distribution
     in full payment in exchange for the stock redeemed as provided in Section
     302 of the Code.

                                       24
<PAGE>
          (5)  For a TB&T Bancshares shareholder who dissents from the Merger
     and receives solely cash in exchange for his, her or its TB&T Bancshares
     common stock, such cash will be treated as having been received by such
     shareholder as a distribution in redemption of his, her or its stock,
     subject to the provisions and limitations in Section 302 of the Code.

     In addition, in the opinion of KPMG, the following will be the federal
income tax consequences to TB&T Bancshares shareholders as a result of the
distribution of shares held pursuant to the Holdback Escrow Agreement:

          (1)  Texas Regional Common Stock dividends paid into the escrow
     created pursuant to the Holdback Escrow Agreement will be taxed to the TB&T
     Bancshares shareholders upon payment of the dividends to the escrow. TB&T
     Bancshares shareholders will be entitled to a deduction in the event the
     dividends, or a portion thereof, are returned to Texas Regional.

          (2)  No gain or loss should be recognized by the shareholders of TB&T
     Bancshares upon distribution of shares of Texas Regional Common Stock from
     the escrow created pursuant to the Holdback Escrow Account.

     KPMG has audited the financial statements of Texas Regional since 1987, and
has provided other financial advisory services from time to time to Texas
Regional. Total fees paid to KPMG by Texas Regional are not material to the
total revenue of KPMG.

     As indicated, neither Texas Regional, nor TRD, nor TB&T Bancshares has
requested or anticipates requesting a ruling from the IRS with regard to the
federal income tax consequences of the proposed merger transaction.

     THIS SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER IS NOT
INTENDED TO BE A SUBSTITUTE FOR CAREFUL TAX PLANNING ON AN INDIVIDUAL BASIS. IN
ADDITION TO THE FEDERAL INCOME TAX CONSEQUENCES DISCUSSED IN THIS
PROSPECTUS/PROXY STATEMENT, CONSUMMATION OF THE MERGER MAY HAVE SIGNIFICANT
FOREIGN, STATE OR LOCAL INCOME TAX CONSEQUENCES WHICH ARE NOT DISCUSSED HEREIN.
ACCORDINGLY, EACH PERSON CONSIDERING THE MERGER IS URGED TO CONSULT SUCH
SHAREHOLDER'S PERSONAL TAX ADVISERS WITH SPECIFIC REFERENCE TO THE EFFECT OF THE
TRANSACTION ON SUCH SHAREHOLDER'S OWN PARTICULAR FACTS AND CIRCUMSTANCES.

GOVERNMENTAL APPROVALS.

     Consummation of the Merger is subject to approval by the shareholders of
TB&T Bancshares, the receipt of required regulatory approvals from the Federal
Reserve Board under the Bank Holding Company Act of 1956, as amended, and the
satisfaction or waiver of other conditions as described in the Agreement. In
addition, the merger of Texas Bank & Trust with and into Texas State Bank is
subject to the approval of the Texas Banking Department. It is expected that the
Federal Reserve Board and the Texas Banking Department will approve the
respective transactions.

     A formal application under the Bank Holding Company Act of 1956 was filed
with the Federal Reserve Board on                , 1997. Upon receipt of Federal
Reserve Board approval, the Merger cannot be consummated until the expiration of
15 days following the date of approval, during which time the United States
Department of Justice, pursuant to the Bank Holding Company Act of 1956, may
bring an action to oppose the Merger. An application was filed with the Texas
Banking Department on              , 1997, for the merger of Texas Bank & Trust
with and into Texas State Bank. Closing of the transaction is contingent upon
receipt of all such approvals.

ACCOUNTING TREATMENT.

     Texas Regional anticipates accounting for the Merger under the
pooling-of-interests method of accounting for financial reporting and for all
other purposes, and the Company has received such assurances as its deems
appropriate that the Merger will qualify for pooling-of-interests accounting
treatment,

                                       25
<PAGE>
including the receipt of a letter from KPMG, which will be updated as of the
effective time of the Merger, to the effect that the Merger will qualify for
pooling-of-interests accounting treatment. Under this accounting method, at the
effective time of the Merger, TB&T Bancshares' assets and liabilities will be
added at their recorded book values to Texas Regional's consolidated balance
sheet, and TB&T Bancshares' shareholders' equity will be added to Texas
Regional's consolidated balance sheet. Income and other financial statements of
Texas Regional issued after consummation of the Merger will be restated
retroactively to reflect the consolidated operations of TB&T Bancshares and
Texas Regional as if the Merger had taken place prior to the periods covered by
such financial statements.

     Because the requirements for pooling-of-interests accounting are complex
and include matters outside of the control of the Company, there can be no
certainty that accounting for the transaction under that method of accounting
will be permitted. The pro forma information contained herein assumes that the
transaction will be accounted for under the pooling-of-interests method.

                   DESCRIPTION OF TEXAS REGIONAL'S SECURITIES

     Texas Regional is authorized to issue Common Stock and preferred stock. A
total of 20,000,000 common shares and 10,000,000 preferred shares are
authorized. As of the date of this Prospectus/Proxy Statement, 13,110,639 shares
of Texas Regional Common Stock are issued and outstanding, and no preferred
shares are issued or outstanding. In addition to the shares proposed to be
issued to TB&T Bancshares shareholders in connection with the Merger, Texas
Regional has agreed to issue up to an aggregate of approximately 985,000 shares
of Texas Regional Common Stock in connection with Texas Regional's proposed
acquisition of Brownsville Bancshares, Inc. (including both shares to be issued
to Brownsville Bancshares shareholders and shares to be issued to Brownsville
Bancshares option holders) and 343,924 shares of Texas Regional Common Stock are
reserved for issuance in connection with options granted to employees under
Texas Regional's employee stock option plans. Further issuance of shares of
Texas Regional Common Stock after the effective time of the Merger would have
the effect of reducing the former TB&T Bancshares shareholders' proportionate
interest in Texas Regional.

     Texas Regional shareholders do not have preemptive rights for the
acquisition of additional Texas Regional shares. Each holder of Texas Regional
Common Stock is entitled to one vote for each share held on all matters
submitted to common shareholders, including election of directors; however, the
holders of Texas Regional Common Stock do not have cumulative voting rights in
the election of directors. The Texas Regional share certificates issued to TB&T
Bancshares shareholders in connection with the Merger will bear legends
describing the fact that the Texas Regional Articles of Incorporation deny
preemptive rights and do not allow cumulative voting in the election of
directors.

     Texas Regional presently has three separate stock option plans, under the
terms of which Texas Regional has granted options to purchase a total of 343,924
shares of the Class A Voting Common Stock to certain key employees for their
purchase. In 1990, Texas Regional adopted the Texas Regional Bancshares, Inc.
Employee Stock Ownership Plan (with 401(k) provisions) (the "KSOP Plan"). As
of September 30, 1997, a total of 505,078 shares of Texas Regional Common Stock
were held for the benefit of Texas Regional employees pursuant to the KSOP. It
is anticipated that any employee benefit plan of TB&T Bancshares or Texas Bank &
Trust will be terminated as of the effective time of the Merger, and employees
of TB&T Bancshares who become employees of Texas Regional and who otherwise
qualify will become participants in the Texas Regional KSOP.

     Holders of Texas Regional common stock are entitled to dividends as and
when declared by the Board of Directors of Texas Regional out of legally
available funds. Texas Regional has declared the following dividends on its
common shares since January 1, 1994:

                                        AGGREGATE       DIVIDENDS
       APPLICABLE TIME PERIOD           DIVIDENDS       PER SHARE
- -------------------------------------   ----------      ---------
January 1, 1994 to December 31,
  1994...............................     $1,486          $0.16
January 1, 1995 to December 31,
  1995...............................      2,478           0.27
January 1, 1996 to December 31,
  1996...............................      3,232           0.27
January 1, 1997 to December 9,
  1997...............................      4,803           0.36

Texas Regional's Board of Directors intends to maintain its present policy of
paying regular quarterly cash dividends. However, the declaration and amount of
future dividends will depend on circumstances existing at the time, including
Texas Regional's earnings, financial condition and capital requirements, as well
as regulatory limitations and such other factors as Texas Regional's Board of
Directors deems relevant.

     The principal assets and sources of income for Texas Regional consists of
its investment in Texas State Bank, which is a separate legal entity. Federal
and state banking regulations applicable to Texas Regional and Texas State Bank
require minimum levels of capital which limits the amounts available for payment
of dividends by Texas State Bank.

     Texas Regional declared a 3-for-2 stock split effected as a stock dividend
to holders of record of its common stock on July 31, 1997, and distributed that
dividend during August 1997. All shares of Texas Regional Common Stock now
outstanding are, and the shares of Texas Regional Common Stock to be

                                       27
<PAGE>
issued in the Merger will be, fully paid and nonassessable with no personal
liability attaching to the ownership thereof.

     In the event of liquidation, after payment of all creditors and after
payment of the liquidation preference applicable to any then-outstanding series
of preferred shares, the holders of Texas Regional Common Stock will be entitled
to receive pro rata any assets remaining for distribution to shareholders.

     Texas Regional has the authority to issue up to 10,000,000 preferred
shares, $1.00 par value per share, although no shares of preferred stock are
presently outstanding. Texas Regional's Board of Directors has the authority to
adopt resolutions establishing and designating one or more series of preferred
shares, and to issue the preferred shares with such rights, privileges and
limitations as the Board may deem appropriate, without approval of the holders
of Texas Regional Common Stock. Upon issuance, the preferred shares may have
dividend rights, liquidation preference or other rights superior to the holders
of shares of Texas Regional Common Stock.

                       COMPARATIVE RIGHTS OF SHAREHOLDERS

     Upon consummation of the transactions contemplated by the Agreement, the
shareholders of TB&T Bancshares will become shareholders of Texas Regional. Both
Texas Regional and TB&T Bancshares are Texas business corporations, organized
under the Texas Business Corporation Act, and, therefore, holders of capital
stock of TB&T Bancshares and holders of Texas Regional Common Stock have similar
rights in many respects. Each shareholder is entitled to one vote for each share
held by that shareholder; each shareholder is entitled to such dividends as the
Board of Directors may declare from legally available funds; and each
shareholder is, upon liquidation, entitled to receive pro rata any assets
distributed to common shareholders.

     Unlike shareholders of TB&T Bancshares, who have preemptive rights, holders
of Texas Regional Common Stock have no preemptive rights to subscribe for the
purchase of any shares of Texas Regional Common Stock which may be issued by
Texas Regional from time to time. Because the number of authorized shares of
Texas Regional Common Stock exceeds the number of issued and outstanding shares,
the Board of Directors of Texas Regional could authorize the sale of up to
5,596,285 shares of Common Stock (less the shares to be issued to TB&T
Bancshares shareholders in the TB&T Bancshares Merger, and shares to be issued
to shareholders and option holders of Brownsville Bancshares, Inc., in
connection with the Brownsville Bancshares, Inc., transaction) without further
authorization or approval from the Texas Regional shareholders. Presently, there
are no preferred shares issued and outstanding, but 10,000,000 preferred shares
are authorized for issuance. The preferred shares may be issued in one or more
series, without further authorization or approval from the Texas Regional
shareholders. Upon liquidation of Texas Regional, the holders of Common Stock
would share in proceeds of liquidation only after the liquidation preference is
paid in respect of any outstanding preferred shares. See "Description of Texas
Regional Securities."

     Like TB&T Bancshares, Texas Regional is registered as a bank holding
company under the Bank Holding Company Act of 1956, as amended, and, therefore,
its activities are limited to banking, activities closely related to banking and
other activities permitted by that Act. Texas Regional in 1996 established a
subsidiary, TSB Securities, Inc., to engage in the securities brokerage
business. In addition, Texas Regional provides data processing services for
other financial institutions and may in the future provide other services in
addition to the present commercial banking business of its subsidiary, Texas
State Bank.

                     RESALES OF TEXAS REGIONAL COMMON STOCK

     For those TB&T Bancshares shareholders who are not "affiliates" of TB&T
Bancshares, the Texas Regional Common Stock received in the Merger may be freely
traded. However, although the shares of Texas Regional Common Stock to be issued
in the proposed merger will have been registered under the Securities Act of
1933, as amended, any public reoffering or sale of such shares by any person who
is an "affiliate" of TB&T Bancshares at the time such merger is submitted to a
vote of the shareholders of TB&T Bancshares will require either (i) the further
registration under the Securities Act of the shares of

                                       28
<PAGE>
Texas Regional Common Stock to be sold; (ii) compliance with applicable
provisions of Rules 144 and 145 promulgated under the Securities Act of 1933
(permitting sales under certain circumstances); or (iii) the availability of an
exemption from such registration. The foregoing restrictions will apply to all
"affiliates" of TB&T Bancshares and Texas Regional and stop transfer
instructions will be given to Texas Regional's transfer agent with respect to
the shares of Texas Regional Common Stock received by them. An "affiliate" is
defined for these purposes to include a "controlling person," which in this
case would mean, generally, a principal shareholder or an executive officer or
director of TB&T Bancshares and may include certain related parties.

     Generally, Rules 144 and 145 would permit an affiliate to sell within any
three-month period a number of shares that does not exceed the greater of one
percent (1%) of the then outstanding shares of Texas Regional Common Stock or
the average weekly trading volume of such stock reported through the NASDAQ
National Market System during the four calendar weeks preceding such sale,
provided that Texas Regional has filed required periodic reports with the
Securities and Exchange Commission and such sales are made in normal "brokers'
transactions" or in transactions directly with a "market maker" without the
solicitation of buy orders by the brokers or such affiliates. Texas Regional
Common Stock is not listed on an exchange but is traded in the NASDAQ National
Market System over-the-counter market. If a present affiliate of TB&T Bancshares
ceases to be an affiliate for a period of at least three months, Rule 145 will
permit that person to sell his or her Texas Regional securities, without
limitation as to amount of securities to be sold, after he or she has been the
beneficial owner of the Texas Regional securities for at least two years as
determined in accordance with paragraph (d) of Rule 144.

     In addition, the executive officers, directors and certain shareholders of
TB&T Bancshares have agreed not to sell, pledge, transfer or otherwise dispose
of their shares of Texas Regional Common Stock until the publication of
financial results covering at least 30 days of post-Merger combined operations
of Texas Regional and TB&T Bancshares, except with the consent of Texas
Regional, to permit Texas Regional to comply with certain requirements imposed
by the Securities and Exchange Commission and the Financial Accounting Standards
Board for Texas Regional's accounting for the Merger as a pooling-of-interests.
See "Information About the Transaction -- Joinder by Certain Shareholders."

                        INFORMATION ABOUT TEXAS REGIONAL

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE.

     Texas Regional has a class of securities registered pursuant to Section 12
of the Securities Exchange Act of 1934 (the "1934 Act"), as amended, and is a
reporting company for purposes of the 1934 Act, and has been for a period of at
least thirty-six months. For this reason, and because Texas Regional meets other
requirements provided by applicable rules and regulations governing registration
of the transaction, as promulgated by the Securities and Exchange Commission,
Texas Regional has elected to incorporate by reference certain information with
respect to the Corporation.

INTERESTS OF CERTAIN NAMED PERSONS.

     No director or executive officer of Texas Regional has any material direct
or indirect financial interest in TB&T Bancshares, or the Merger, other than as
a director, executive officer or shareholder of Texas Regional. However,
McGinnis, Lochridge & Kilgore, L.L.P., has rendered an opinion concerning the
validity of the securities being offered pursuant to this Prospectus/Proxy
Statement and certain other matters. Joe M. Kilgore, a partner in the firm, is a
Director of Texas Regional and is the beneficial owner, as of September 30,
1997, of approximately 277,510 shares of Texas Regional Common Stock.

OPTION PLANS.

     At a meeting of the Texas Regional Board of Directors held on December 9,
1997, the Board adopted a new incentive stock option plan and a new nonstatutory
stock option plan for the benefit of employees of the company. The total number
of shares to be issued under the Texas Regional Bancshares, Inc., 1997 Incentive
Stock Option Plan is 100,000 shares of Texas Regional Common Stock, and the
total number of

                                       29
<PAGE>
shares to be issued under the Texas Regional Bancshares, Inc., 1997 Nonstatutory
Stock Option Plan is 125,000 shares of Texas Regional Common Stock. Both plans
were adopted subject to receipt of shareholder approval. No options have been
granted pursuant to either the 1997 Incentive Stock Option Plan or the 1997
Nonstatutory Stock Option Plan.

PENDING TRANSACTIONS.

     On October 20, 1997, Texas Regional entered into an Agreement and Plan of
Reorganization for the acquisition by merger of Brownsville Bancshares, Inc.
("Brownsville Bancshares"). As of September 30, 1997, Brownsville Bancshares
had total assets of $97.4 million, total loans (net of allowance for loan
losses) of $41.6 million, and total deposits of $84.4 million. Brownsville
Bancshares is expected to be merged with and into TRD as soon as applicable
conditions, including receipt of regulatory approval, are satisfied. Texas
Regional currently expects the Brownsville Bancshares transaction to be closed
contemporaneously with the closing of the TB&T Bancshares transaction, although
neither transaction is contingent upon the closing of the other. The
shareholders of Brownsville Bancshares will receive an aggregate of
approximately 947,164 shares of Texas Regional Common Stock in exchange for
their Brownsville Bancshares shares in connection with the merger transaction,
and holders of options to acquire Brownsville Bancshares shares will receive an
aggregate of approximately 37,836 shares of Texas Regional Common Stock in
exchange for, and in consideration of the termination of, their Brownsville
Bancshares options. Brownsville Bancshares' wholly owned subsidiary, BNB
Bancshares, Inc., will also be merged with and into TRD, and BNB Bancshares,
Inc.'s subsidiary, Brownsville National Bank, will be merged with and into Texas
State Bank. Brownsville National Bank operates from two banking locations, one
each on East Elizabeth Street and Boca Chica Boulevard in Brownsville, Texas.

     In November 1997, Texas Regional entered into an agreement in principle for
the acquisition by merger of Raymondville Bancorp, Inc. ("Raymondville
Bancorp"). As of September 30, 1997, Raymondville Bancorp had total assets of
$60.4 million, total loans (net of allowance for loan losses) of $25.4 million,
and total deposits of $53.5 million. If the parties successfully negotiate a
mutually acceptable definitive agreement, Raymondville Bancorp will be merged
with a newly formed subsidiary of TRD as soon as applicable conditions,
including receipt of regulatory approval, are satisfied. As part of the
agreement in principle with Raymondville, the sole shareholder of Raymondville
has agreed to bear a portion of losses related to stolen or forged money orders
deposited into certain accounts held by Raymondville's wholly owned subsidiary,
Bank of Texas; however, there can be no assurance that the losses incurred on
those accounts and related return items will not exceed the limited amount of
the shareholder's reimbursement obligation and collateral provided by the
account holder. Texas Regional currently expects the Raymondville Bancorp
transaction to be closed contemporaneously with or as soon as practicable
following the closing of the TB&T Bancshares transaction, although neither
transaction is contingent upon the closing of the other. Under the agreement in
principle, which is not binding on either Texas Regional or Raymondville, upon
closing, the sole shareholder of Raymondville Bancorp would receive an aggregate
of $9,600,000 cash in exchange for his Raymondville Bancorp shares, an affiliate
of Raymondville Bancorp would receive $100,000 in consideration of a covenant
not to compete, and Raymondville Bancorp's wholly owned subsidiary, Bank of
Texas of Raymondville, would be merged with and into Texas State Bank. Bank of
Texas operates from two banking locations, one each in Raymondville, Texas, and
at 2000 F.M. 802 in Brownsville, Texas.

     If the Merger with TB&T Bancshares, the merger with Brownsville Bancshares
and the merger with Raymondville Bancorp are all consummated, as planned, Texas
State Bank will have a total of twenty-one full service banking locations in the
Rio Grande Valley of Texas.

                       INFORMATION ABOUT TB&T BANCSHARES

DESCRIPTION AND DEVELOPMENT OF BUSINESS.

     Texas Bank & Trust was chartered as a Texas state bank, under the laws of
State of Texas, in 1979, and opened for business in 1979. TB&T Bancshares was
chartered in 1981, became a bank holding

                                       30
<PAGE>
company upon its acquisition of Texas Bank & Trust in 1981. Substantially all of
the assets and earnings of TB&T Bancshares is derived from the ownership and
operation of Texas Bank & Trust.

     Since it opened for business, TB&T Bancshares has provided retail and
commercial banking services for customers in Brownsville, Texas and adjacent
areas of the Rio Grande Valley. At September 30, 1997, TB&T Bancshares employed
approximately 31 persons. Texas Bank & Trust's banking house is located at 3201
Central Boulevard, Brownsville, Texas, and the bank has no branch locations.
TB&T Bancshares' telephone number is (956) 546-1771.

     Texas Bank & Trust provides its customers with a variety of banking
services. For businesses, Texas Bank & Trust offers checking facilities,
certificates of deposit, short term loans for working capital purposes, mortgage
loans, term loans for fixed assets and expansion needs and other commercial
loans to fit the needs of its business customers. Where the borrowing needs of
customers exceed the limits of Texas Bank & Trust for any one customer it may
participate with other banks in making such loans. The services provided for
individuals by Texas Bank & Trust include checking accounts, savings accounts,
certificates of deposit and mortgage and consumer loan programs, including
installment loans for home repairs and for the purchases of consumer goods,
including automobiles, trucks and boats. Texas Bank & Trust also provides
travelers checks and money orders. Texas Bank & Trust does not provide trust
services and does not operate a trust department.

     TB&T Bancshares has had transactions with its officers and directors and
affiliates of its officers and directors. Substantially all transactions have in
the recent past been in the ordinary course of business on substantially the
same terms as those prevailing for comparable transactions with others.

     All employee benefit plans of TB&T Bancshares are expected to be terminated
as of the effective time of the Merger. Employees of TB&T Bancshares who become
employees of Texas Regional will be entitled to participate in employee benefit
plans offered generally by Texas Regional to its employees, and, if they meet
eligibility requirements of the Texas Regional KSOP, will become participants in

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                      OPERATIONS OF TB&T BANCSHARES, INC.

     The following discussion and analysis presents some of the more pertinent
factors affecting TB&T Bancshares at December 31, 1996 and 1995, and September
30, 1997, and the results of operations of TB&T Bancshares for the three years
ended December 31, 1996, and the nine months ended September 30, 1997 and 1996.
This discussion should be read in conjunction with the financial statements,
notes thereto and other financial information appearing elsewhere in this
Prospectus/Proxy Statement.

                             RESULTS OF OPERATIONS

GENERAL.

     The earnings of TB&T Bancshares depend primarily on TB&T Bancshares' net
interest income (i.e., the difference between the income earned on TB&T
Bancshares' loans and investments and the interest paid on its deposits and
other borrowed funds). Among the factors affecting net interest income are the
type and volume of its deposits and other borrowed funds, and the relative
sensitivity of its interest-earning assets and its interest-bearing liabilities
to changes in market interest rates.

     TB&T Bancshares' income is also affected by fees it receives from other
banking services, by its provision for loan losses and by the level of its
operating expenses. All aspects of TB&T Bancshares' operations are affected by
general market, economic, and competitive conditions.

     TB&T Bancshares reported net income of $422 thousand for the nine month
period ended September 30, 1997, a decrease of $12 thousand from net income of
$434 thousand for the nine month period ended September 30, 1996. Pretax income
was $621 thousand for the nine months ended September 30, 1997, a decrease of
$35 thousand from the $656 thousand earned during the nine months ended
September 30, 1996. TB&T Bancshares had net income of $581 thousand for the year
ended December 31, 1996, $532 thousand for the year ended December 31, 1995, and
$354 thousand for the year ended December 31, 1994.

     Changes occurring in the major components of TB&T Bancshares' income
statements for such periods are discussed below.

NET INTEREST INCOME.

     Net interest income is the primary source of income for TB&T Bancshares and
represents the amount by which interest generated by earning assets exceeds the
cost of funds, primarily interest paid to TB&T Bancshares' depositors on
interest-earning accounts. Taxable-equivalent net interest income was $1.6
million for the nine months ended September 30, 1997, a 13.63% increase from
taxable-equivalent net interest income of $1.4 million for the nine months ended
September 30, 1996. Average rates earned on interest-earning assets increased to
8.54% as of September 30, 1997 from 8.06% as of September 30, 1996. Average
loans of $21.6 million for the nine months ended September 30, 1997 increased
10.34% over average loans of $19.6 million for the same period in 1996. Average
interest-bearing deposits for the nine months ended September 30, 1997 were
$30.2 million, a small increase over average interest-bearing deposits of $30.1
million for the same period in 1996.

     Taxable-equivalent net interest income for the year ended December 31, 1996
was $1.9 million, an increase of 2.37% over taxable-equivalent net interest
income of $1.8 million for the same period in 1995. Average loans of $19.9
million for the year ended December 31, 1996 increased 9.52% over average loans
of $18.1 million for the same period in 1995. Average interest-bearing deposits
for the year ended December 31, 1996 were $30.0 million, an increase of 1.19%
over average interest-bearing deposits of $29.6 million for the same period in
1995.

     Taxable-equivalent net interest income was $1.8 million for the year ended
December 31, 1995, a 7.14% increase over taxable-equivalent net interest income
of $1.7 million for 1994. Average loans of $18.1 million for the year ended
December 31, 1995 increased 13.88% over average loans of $15.9 million for the
same period in 1994. Average interest-bearing deposits for the year ended
December 31, 1995 were $29.6

                                       34
<PAGE>
million, a decrease of 7.87% from average interest-bearing deposits of $32.2
million for the same period in 1994.

     The net yield on interest-earning assets increased 51 basis points for the
nine months ended September 30, 1997 compared to September 30, 1996. The net
yield increased primarily due to a recovery of interest on a previously
charged-off real estate loan and a slight increase in interest-earning assets.

     The net yield on interest-earning assets decreased by 7 basis points for
the year ended December 31, 1996 compared to the year ended December 31, 1995.
During this period yields on interest-earning assets declined by 4 basis points
while rates on interest-bearing liabilities increased by 17 basis points.

     The following table sets forth for the periods indicated an analysis of net
interest income by each major category of interest-earning assets and
interest-bearing liabilities. The rates earned and paid on each major type of
asset and liability account are set forth beside the average level in the
account for the period.

(1) For analytical purposes, income from tax-exempt assets, primarily securities
    issued by state and local governments or authorities, is adjusted by an
    increment which equates tax-exempt income to interest from taxable assets
    (assuming a 34% effective federal income tax rate).

     Changes in interest income and interest expense can result from variances
in both volume and rate. TB&T Bancshares has an asset and liability management
strategy designed to provide a proper balance between rate sensitive assets and
rate sensitive liabilities to attempt to maximize interest margins, and to
provide adequate liquidity for anticipated needs.

PROVISION FOR LOAN LOSSES.

     TB&T Bancshares' allowance for loan losses is established through charges
to operating income in the form of the provision for loan losses. Actual loan
losses or recoveries of loan losses are charged or credited directly to the
allowance for loan losses.

     TB&T Bancshares recorded no provision for loan losses for the nine months
ended September 30, 1997 nor for the nine months ended September 30, 1996. The
allowance for loan losses expressed as a percentage of outstanding loans was
2.16% and 2.41% at September 30, 1997 and September 30, 1996, respectively. TB&T
Bancshares recorded no provision for loan losses for the years ended December
31, 1996, 1995, and 1994. TB&T Bancshares' allowance for loan losses as a
percentage of outstanding loans was 2.40% at December 31, 1996, 2.75% at
December 31, 1995, and 3.01% at December 31, 1994.

NONINTEREST INCOME.

     Noninterest income, which includes all service charges and fees, decreased
27.0% to $233 thousand for the nine months ended September 30, 1997 from $319
thousand for the nine months ended September 30, 1996. The change was primarily
due to the decrease in service charges on deposit accounts and other operating
income. Noninterest income increased to $390 thousand for the year ended
December 31, 1996, a 21.88% increase from $320 thousand for the year ended
December 31, 1995. The increase was mainly due to increased regular service
charges and other operating income. The increase in other operating income
during 1996 resulted from a gain recorded as the result of the sale of land
originally purchased for expansion.

                                       39
<PAGE>
     Noninterest income decreased 6.71% to $320 thousand for the year ended
December 31, 1995 from $343 thousand for the year ended December 31, 1994. The
decrease was due to decreased other service charges and other operating income.

NONINTEREST EXPENSE.

     Noninterest expense included expenses which TB&T Bancshares incurs in the
course of operations such as employee compensation and benefits, occupancy
expense, data processing charges, communication expense, professional fees,
advertising, supplies, and depreciation and amortization of furniture and
equipment. These expenses increased $132 thousand or 12.83% for the nine months
ended September 30, 1997 compared to the nine months ended September 30, 1996.
The primary reason for the increase in other noninterest expense for the nine
months ended September 30, 1997 compared to the same period of 1996 was the
payment of various claims in connection with an alleged misappropriation of
funds by an employee. Management believes any further losses will be reimbursed
by TB&T Bancshares' insurance carrier.

     Noninterest expenses were $1.4 million in 1996, 1995, and 1994. During
1995, TB&T Bancshares installed an in-house computer to process transactions
which were previously processed by an independent data processing company. As a
result, salaries and employee benefits and equipment expense have experienced an
increase while other noninterest expenses have decreased.

FEDERAL INCOME TAXES.

     TB&T Bancshares' provision for income taxes was $199 thousand and $222
thousand for the nine month periods ended September 30, 1997 and 1996,
respectively.

     TB&T Bancshares' provision for income taxes was $289 thousand for year end
1996, $219 thousand for year end 1995 and $241 thousand for year end 1994.

              CAPITAL RESOURCES, LIQUIDITY AND FINANCIAL CONDITION

CAPITAL RESOURCES.

     The Federal Reserve, the Federal Deposit Insurance Corporation ("FDIC")
and the Texas Department of Banking have adopted risk-based and leverage capital
measures to assist in the assessment of the capital adequacy of the holding
companies and banks they regulate. The Federal Reserve regulations apply to TB&T
Bancshares and the FDIC regulations apply to Texas Bank & Trust of Brownsville
("the Bank"). Although there are differences between these regulations, in
general the Federal Reserve and the FDIC regulations employ uniform capital
ratios and consistent capital frameworks. The principal objectives of the
risk-based measures are to: (i) make regulatory capital requirements more
sensitive to differences in risk profiles among financial institutions; (ii)
factor off-balance-sheet exposures into the assessment of capital adequacy;
(iii) minimize disincentives to holding liquid, low-risk assets; and (iv)
achieve greater consistency in the evaluation of the capital adequacy of
financial institutions.

     The risk-based capital guidelines include both a definition of capital and
a framework for calculating risk-weighted assets by assigning assets and
off-balance-sheet items to broad risk categories. The financial institution's
risk-based capital ratio is calculated by dividing its qualifying capital (the
numerator of the ratio) by its risk-weighted assets (the denominator).

     The risk-based capital ratio focuses principally on broad categories of
credit risk and, effective as of January 1997, market risk. The risk-based ratio
does not, however, incorporate other factors that can affect a bank's financial
condition. These factors include overall interest rate exposure, liquidity,
funding risks, the effectiveness of loan and investment policies, and
management's ability to monitor and control financial and operating risks.

     The financial institution's qualifying total capital consists of two types
of capital components: "core capital elements" (comprising Tier 1 capital) and
"supplementary capital elements" (comprising Tier 2 capital). Certain assets
are deducted from a financial institution's capital for the purpose of
calculating the risk-based capital ratio.

                                       40
<PAGE>
     Assets and credit equivalent amounts of off-balance-sheet items are
assigned to one of four risk categories, according to certain criteria. The
aggregate dollar value of the amount in each category is then multiplied by the
risk weight associated with that category. The resulting weighted values from
each of the risk categories are added together, and this sum is the financial
institution's total risk-weighted assets that comprise the denominator of the
risk-based capital ratio. Assets deducted from a bank's capital in determining
the numerator of the risk-based capital ratio are not included as part of the
financial institution's risk-weighted assets.

     Risk weights for off-balance-sheet items are determined by a two-step
process. First, the "credit equivalent amount" of off-balance-sheet items is
determined, in most cases by multiplying the off-balance-sheet items by a credit
conversion factor. Second, in most cases, the credit equivalent amount is
assigned to the appropriate risk category according to designated criteria.

     Financial institutions are required to maintain a minimum risk-based
capital ratio of total capital (after deductions) to risk-weighted assets of 8%.
In general, 50% of this ratio must consist of Tier 1 capital. Certain
restrictions and limitations also apply regarding the calculation of Tier 1
capital. Tier 2 capital elements that are not used as part of Tier 1 capital
generally will qualify for inclusion in a financial institution's capital base
up to a maximum of 100% of the financial institution's Tier 1 capital. At
September 30, 1997 TB&T Bancshares' Tier 1 risk-based capital ratio was 12.39%
with a total risk-based capital ratio of 13.64% and the Bank's Tier 1 risk-based
capital ratio was 12.42% and its total risk-based capital ratio was 13.67%. At
year end 1996, TB&T Bancshares' Tier 1 capital ratio was 13.12% and its total
risk-based capital ratio was 14.37%, and the Bank's Tier 1 capital ratio was
12.43% and its total risk-based capital ratio was 13.68%. At year end 1995, TB&T
Bancshares' Tier 1 capital ratio was 12.44% and its total risk-based capital
ratio was 13.69%, and the Bank's Tier 1 capital ratio was 11.88% and its total
risk-based capital ratio was 13.13%.

     In addition, the Federal Reserve and the FDIC have promulgated capital
leverage guidelines designed to supplement the risk-based capital guidelines.
The principal objective of the leverage ratio is to address the extent to which
a financial institution could leverage its equity capital base. The Federal
Reserve and the FDIC require their regulated institutions to meet a minimum
leverage capital requirement of Tier 1 capital to total assets of not less than
3% for an institution that is not anticipating or experiencing significant
growth and is highly rated (i.e., a composite examination rating of 1 on a scale
of 1 to 5). Institutions that the Federal Reserve and the FDIC determine are
anticipating or experiencing significant growth or that are not highly rated
must meet a minimum leverage ratio of 3% plus an additional cushion of at least
100 to 200 basis points.

     TB&T Bancshares' leverage ratio was 8.84% at year end 1996 and 8.13% at
year end 1995. At September 30, 1997 the leverage ratio was 9.10%. The Bank's
leverage ratio was 8.38% at year end 1996 and 7.76% at year end 1995. At
September 30, 1997 the Bank's leverage ratio was 9.12%.

LIQUIDITY.

     TB&T Bancshares' asset and liability management policy is intended to
maintain adequate liquidity and thereby enhance its ability to raise funds to
support asset growth, meet deposit withdrawals and lending needs, maintain
reserve requirements, and otherwise sustain operations. TB&T Bancshares
accomplishes this through management of the maturities of its interest-earning
assets and interest-bearing liabilities. Liquidity is monitored and overall
interest rate risk is assessed through reports showing both sensitivity ratios
and existing dollar "gap" data. TB&T Bancshares believes its present position
to be adequate to meet its current and future liquidity needs.

     The liquidity of TB&T Bancshares is maintained in the form of readily
marketable investment securities, demand deposits with commercial banks, vault
cash and federal funds sold. While the minimum liquidity requirement for banks
is determined by federal bank regulatory agencies as a percentage of deposit
liabilities, TB&T Bancshares' management monitors liquidity requirements as
warranted by interest rate trends, changes in the economy and the scheduled
maturity and interest rate sensitivity of the investment and loan portfolio,
deposits and anticipated loan fundings. In addition to the liquidity provided by
the

                                       41
<PAGE>
foregoing, TB&T Bancshares has correspondent relationships with other
institutions with available secured lines of credit to purchase overnight funds
should additional liquidity be needed. These lines are subject to restrictions
such as the financial strength of TB&T Bancshares and the lender's ability to
facilitate credit.

     On March 1, 1994, TB&T Bancshares adopted the provisions of FAS 115. At
September 30, 1997, TB&T Bancshares' investment portfolio totaled $16.5 million
of which $10 thousand are classified as available for sale.

     Average noninterest-bearing demand deposits were $8.8 million for the nine
months ended September 30, 1997, an increase of $431 thousand over the average
balance for the same period in 1996. Average interest-bearing deposits were
$30.2 million for the nine months ended September 30, 1997 compared to $30.1
million for the same period in 1996.

     Average noninterest-bearing demand deposits were $8.4 million, $7.5 million
and $6.8 million for the years ended December 31, 1996, 1995 and 1994,
respectively. Average interest-bearing deposits for the same years were $30.0
million, $29.6 million and $32.2 million, respectively.

     Net cash generated by operating activities was $424 thousand for the nine
months ended September 30, 1997 and $636 thousand for the same period in 1996.
Proceeds from sales, principal paydowns, and maturities of investment securities
were $4.0 million and $2.7 million for the same periods. TB&T Bancshares
utilized these funds to originate loans and purchase investment securities. TB&T
Bancshares purchased investment securities of $3.0 million and $4.0 million
during the nine months ended September 30, 1997 and 1996, respectively.

     Net cash generated by operating activities was $616 thousand, $1.0 million
and $935 thousand for the years 1996, 1995, and 1994, respectively. Proceeds
from sales, principal paydowns, and maturities of investment securities were
$5.5 million, $8.4 million and $9.6 million for the same periods. TB&T
Bancshares utilized these funds to originate loans and purchase investment
securities. TB&T Bancshares purchased investment securities of $5.8 million,
$4.2 million and $8.8 million in 1996, 1995, and 1994, respectively.

     Loan originations and advances net of repayments amounted to $1.8 million
for the nine months ended September 30, 1997 and $1.1 million for the nine
months ended September 30, 1996. Loan originations and advances net of
repayments amounted to $1.2 million, $2.4 million and $1.9 million for the years
ended December 31, 1996, 1995 and 1994, respectively.

     Funds utilized for the purchase of bank premises and equipment were $6
thousand and $253 thousand for the nine months ended September 30, 1997 and
1996, respectively. Funds utilized for the purchase of bank premises and
equipment were $261 thousand, $319 thousand and $12 thousand during 1996, 1995
and 1994, respectively.

INTEREST RATE SENSITIVITY.

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

     Maintaining an equilibrium between rate sensitive assets and liabilities
will reduce some of the risk associated with diverse changes in market rates,
but it will not guarantee a stable net interest spread because yields and rates
may change simultaneously and by different amounts. These changes in market
spreads could materially affect the overall net interest spread even if assets
and liabilities were perfectly matched. If more assets than liabilities reprice
within the given period, an asset sensitive position or "positive gap" is
created. During a positive gap, a decline in market rates will have a negative
impact on net interest income. Alternatively, where more liabilities than assets
reprice in a given period, a liability sensitive position or

                                       42
<PAGE>
"negative gap" is created (rate sensitivity ratio is less than 100%) and a
decline in interest rates will have a positive impact on net interest income.

     The following table shows interest sensitivity gaps for these different
intervals as of September 30, 1997.

(1) Rate sensitive interest-earning assets less rate sensitive interest-bearing
    liabilities.

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

     At September 30, 1997, total loans net of unearned income and allowance for
possible loan losses exceeded year end 1996 figures by $1.8 million or 9.13%.
Total loans net of unearned income and allowance for possible loan losses
increased $1.2 million or 6.31% to $19.8 million for the year ended December 31,
1996 compared to $18.6 million at December 31, 1995.

ALLOWANCE FOR LOAN LOSSES AND RISK ELEMENTS.

     The provision for loan losses represents a determination by TB&T
Bancshares' management of the amount necessary to be charged to operating income
and transferred to the allowance for loan losses to maintain a level which it
considers adequate in relation to the risk of future losses inherent in the loan
portfolio. It is TB&T Bancshares' policy to provide for exposure to losses of
specifically identified credits, and a general allowance for the remainder of
the loan portfolio, and, while it is also TB&T Bancshares' policy to charge off
in the current period those loans in which a loss is deemed to exist, risks of
future losses also exist which cannot be quantified precisely or attributed to
particular loans or classes of loans.

     In assessing the adequacy of its allowance for loan losses, management
relies predominantly on its ongoing review of the loan portfolio, which is
undertaken both to ascertain whether there are probable losses which must be
charged off and to assess the risk characteristics of individually significant
loans and of the portfolio in aggregate. This review takes into consideration
the judgments of the responsible lending officers, the Chief Executive Officer,
and the Board of Directors, and also those of bank regulatory agencies that
review the loan portfolio as part of their regular examinations of TB&T
Bancshares.

     In evaluating the allowance for loan losses, management also considers TB&T
Bancshares' loan loss experience, the amount of past due and nonperforming
loans, current and anticipated economic conditions, changes in lending and
collection procedures, changes in loan volumes and the quality of TB&T
Bancshares' loan review system.

     The allowance for loan losses at September 30, 1997 was $477 thousand,
compared to $487 thousand at December 31, 1996, $527 thousand at December 31,
1995, and $511 thousand at December 31, 1994. Although additional losses may
occur, management believes the allowance for loan losses to be adequate as of
the dates presented.

     The accrual of interest on a loan is discontinued when, in the opinion of
management (based upon such criteria as default in payment, asset deterioration,
decline in cash flow, recurring operating loss, declining sales, bankruptcy and
other financial conditions which could result in default), the borrower's
financial condition is such that the collection of interest is doubtful. At
September 30, 1997 loans totaling $177 thousand, or 0.80% of the total net loans
outstanding, were on nonaccrual basis and, therefore, no income was being
recognized. As of year end 1996, loans totaling $348 thousand, or 1.71% of total
net loans outstanding, were on a nonaccrual basis and, therefore, no income was
being recognized. Management believes the risks of collection of the principal
amounts of these loans not to be significant.

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

     Nonaccrual loans decreased by $198 thousand to $177 thousand at September
30, 1997, from $375 thousand at September 30, 1996. For the years ended December
31, 1996, 1995 and 1994, total nonaccrual, past due greater than 90 days and
renegotiated loans were $695 thousand, $321 thousand and $483 thousand,
respectively.

                                 LEGAL OPINION

     McGinnis, Lochridge & Kilgore, L.L.P., has rendered an opinion concerning
the validity of the securities being offered pursuant to this Prospectus/Proxy
Statement and certain other matters. Joe M. Kilgore, a partner in the firm, is a
Director of Texas Regional and is the beneficial owner, as of September 30,
1997, of approximately 277,510 shares of Texas Regional Common Stock. Ford &
Ferraro, L.L.P., counsel to TB&T Bancshares, is expected to render a legal
opinion as to certain matters in connection with the closing of the Merger.

                                INDEMNIFICATION

     Texas Regional's Bylaws include provisions authorizing Texas Regional to
indemnify its officers, directors, employees and agents to the full extent
permitted by law. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers or persons
controlling Texas Regional, Texas Regional has been informed that in the opinion
of the Securities and Exchange Commission, such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.

                                 OTHER MATTERS

     TB&T Bancshares' Board of Directors does not know of any matter to be
presented at the Special Meeting of the Shareholders of TB&T Bancshares other
than those set forth above. If any other matters are properly brought before the
meeting or any adjournment thereof, the enclosed proxy will be voted in
accordance with the recommendation of the TB&T Bancshares Board of Directors
unless an appropriate indication is made on the proxy. See "Summary -- The
Meeting."

                                    ANNEX A

                      AGREEMENT AND PLAN OF REORGANIZATION

     This Agreement and Plan of Reorganization (hereinafter called the
"Agreement"), dated as of October 15, 1997, is executed by and between Texas
Regional Bancshares, Inc., McAllen, Texas, a Texas corporation ("Texas
Regional") and TB&T Bancshares, Inc., a Texas corporation ("TB&T Bancshares").

     Texas Regional operates a commercial banking business in Texas through its
wholly owned subsidiary, Texas State Bank, a Texas state banking association
("Texas State Bank"). Texas Regional has formed a new wholly-owned Delaware
subsidiary corporation, Texas Regional Delaware, Inc. ("TRD"), for purposes of
facilitating the transaction herein described. TB&T Bancshares operates a
commercial banking business in Texas through its wholly owned subsidiary, Texas
Bank & Trust Company of Brownsville ("TB&T"). As used in this Agreement, any
reference to the subsidiaries of TB&T Bancshares includes any and all direct or
indirect subsidiaries of TB&T Bancshares, including specifically but without
limitation TB&T.

     The undersigned shareholders of TB&T Bancshares (the "Majority
Shareholders") join into the execution hereof for the limited purpose of
evidencing their consent to and approval of the transaction herein described and
to confirm that each has agreed to vote for the transaction at the TB&T
Bancshares shareholders' meeting and each has agreed to support and recommend
the transaction to the other shareholders of TB&T Bancshares.

                                  WITNESSETH:

     This Agreement provides for the merger of TB&T Bancshares with and into
TRD, a newly formed wholly-owned subsidiary of Texas Regional, pursuant to the
terms of this Agreement and Plan of Reorganization. As a result of the merger,
the shareholders of TB&T Bancshares (other than any shareholder exercising
dissenters' rights of appraisal) will receive shares of Texas Regional Class A
Voting Common Stock in exchange for their shares of TB&T Bancshares common
stock. Upon the closing of the transaction, it is anticipated that (i) TB&T
Bancshares shall be merged with and into TRD, and will cease its separate
existence, and (ii) TB&T will be merged with and into Texas State Bank and TB&T
will cease its separate existence.

     As a result of the merger of TB&T Bancshares with and into TRD, all rights,
privileges, immunities, powers and franchises of each of TRD and TB&T Bancshares
shall be merged into TRD as the surviving corporation. Without any other action,
at the Effective Time, TRD shall be vested with all property, real, personal and
mixed, of the merging corporations and shall thereafter possess all of the
interests, both public and private, of each of the merging corporations and all
claims of creditors of each of TRD and TB&T Bancshares shall survive and any
liens shall be preserved unimpaired in TRD as the surviving corporation. All of
the foregoing shall be effected to and as set forth in this Agreement and in a
Certificate of Merger (the "Certificate of Merger") to be executed by and
among TRD and TB&T Bancshares, in the form required by applicable provisions of
the Delaware General Corporation Law.

     In addition, at or immediately following the Effective Time of the merger
of TB&T Bancshares with and into TRD, TB&T will be merged with and into Texas
State Bank, and all rights, privileges, immunities, powers and franchises of
each of Texas State Bank and TB&T 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
TB&T and Texas State Bank and shall thereafter possess all of the interests,
both public and private, of each of TB&T and Texas State Bank, and all claims of
creditors of each of Texas State Bank and TB&T shall survive and any liens shall
be preserved unimpaired in Texas State Bank as the surviving banking
association. All of the foregoing shall be effected pursuant to and as set forth
in an Agreement of Merger to be executed by and among Texas State Bank and TB&T.

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

                                   ARTICLE 1
                                 PLAN OF MERGER

     1.1.  THE MERGER.  Upon and subject to the terms and provisions hereof, at
the Effective Time, as hereafter defined, TB&T Bancshares shall be merged with
and into TRD (the "Merger"). The effect of the Merger is that the separate
existence of TB&T Bancshares shall cease. Following approval of such merger
transaction by applicable regulatory authorities and the shareholders of TB&T
Bancshares, and the fulfillment of other conditions precedent to such merger
transaction as herein described, TRD and TB&T Bancshares shall each execute and
deliver the Certificate of Merger, in the form required by the Delaware General
Corporation Law, for filing with the Secretary of State of Delaware. At the
Effective Time of the Merger, the rights of the shareholders of TB&T Bancshares
shall, without the requirement of further action on the part of the
shareholders, immediately be converted into the right to receive shares of Texas
Regional Class A Voting Common Stock as herein provided, and each such
shareholder shall cease to be a shareholder of TB&T Bancshares and his, her or
its share certificate shall for all purposes be deemed only to represent a right
to receive shares of Texas Regional Class A Voting Common Stock pursuant to this
Agreement.

     1.2.  CONSIDERATION TO TB&T BANCSHARES SHAREHOLDERS.

     1.2.1.  At the Effective Time (as hereinafter defined), all of the
outstanding shares of TB&T Bancshares capital stock shall be converted into the
right to receive Texas Regional Class A Voting Common Stock as hereafter
described. At the Effective Time, the shares of TB&T Bancshares capital stock
held by each shareholder (other than any shareholder validly exercising his or
her dissenters' rights of appraisal) shall be automatically converted without
any further action on the part of the holder thereof, into:

          0.1522126 of a share of Texas Regional Class A Voting Common
     Stock for each share of TB&T Bancshares held (all such shares being
     collectively herein called the "Closing Shares"), to be distributed
     to the shareholders of TB&T Bancshares upon the Closing, as herein
     described; plus

          0.0294605 of a share of Texas Regional Class A Voting Common
     Stock for each share of TB&T Bancshares held (all such shares being
     collectively herein called the "Holdback Escrow Shares"), to be
     deposited into the escrow created pursuant to the Holdback Escrow
     Agreement hereinafter described, to be either distributed to the
     shareholders of TB&T Bancshares as therein described, or returned to
     Texas Regional for cancellation upon the occurrence of certain
     conditions as therein provided. The Holdback Escrow Shares shall be
     held pursuant to the Holdback Escrow Agreement in the form of SCHEDULE
     1.7, to be executed and entered into effective as of the time of
     Closing.

Fractional shares shall not be issued, and any amount attributable to fractional
shares shall be paid in cash in an amount equal to the product of $30.025
multiplied by the fraction of a Texas Regional share that would otherwise have
been issued. Amounts payable in respect of shareholders exercising dissenters'
rights shall be payable by the surviving corporation in the merger transaction
in such amounts and at such times as such payments are required pursuant to
applicable provisions of law respecting the exercise of dissenters' rights. The
aggregate number of shares of Texas Regional Class A Voting Common Stock to be
delivered to the shareholders of TB&T Bancshares in exchange for their shares of
TB&T Bancshares and as Holdback Escrow Shares to be held and distributed by the
escrow agent named in the Holdback Escrow Agreement shall be an aggregate of
308,076 shares (which, based on $30.025 per share, totals an aggregate of
$9,250,000), less any shares attributable to fractional shares, less any shares
attributable to shareholders that have exercised dissenters' rights in
connection with the transactions.

     1.2.2.  Certificates evidencing the Closing Shares to which each
shareholder becomes entitled shall be delivered by Texas Regional to each TB&T
Bancshares shareholder upon surrender of such shareholder's

                                      A-2
<PAGE>
share certificate or certificates evidencing shares of TB&T Bancshares stock.
Texas Regional share certificates for the Closing Shares to which such TB&T
Bancshares shareholders are entitled shall be delivered at the time of Closing
to those TB&T Bancshares shareholders who have surrendered their TB&T Bancshares
share certificates at or prior to the date of Closing, either (i) by mailing the
same to the shareholder at the shareholder's address as stated on the stock
transfer records of TB&T Bancshares, or (ii) by such other arrangements as may
be mutually agreed by and between such former TB&T Bancshares shareholder and
Texas Regional. Any delivery of Texas Regional share certificates representing
Closing Shares to shareholders who surrender their TB&T Bancshares share
certificates following the date of Closing shall be mailed to the former TB&T
Bancshares shareholder within a reasonable period of time following receipt of
the shareholder's TB&T Bancshares share certificate. The stock transfer records
of TB&T Bancshares shall for all purposes be closed as of the Effective Time,
and no transfer of record of any of the shares of TB&T Bancshares capital stock
shall take place thereafter. The share certificates for Holdback Escrow Shares
to which former TB&T Bancshares shareholders become entitled shall be delivered,
if such TB&T Bancshares has theretofore delivered his or her TB&T Bancshares
certificate to be cancelled, as and when required by the terms of the Holdback
Escrow Agreement. Any share certificates for Holdback Escrow Shares to which a
former TB&T Bancshares shareholder has become entitled, but which shareholder
has not yet at that time delivered his or her TB&T Bancshares certificate to be
cancelled, shall be retained by Texas Regional until a reasonable period of time
following the receipt of such shareholder's TB&T Bancshares share certificate,
as with the certificate representing Closing Shares to which such shareholder
thus becomes entitled.

     1.2.3.  Any Texas Regional share certificate that would otherwise have been
delivered pursuant to section 1.2.2 to any shareholder of TB&T Bancshares who
has exercised his, her or its dissenters' rights of appraisal pursuant to
applicable provisions of law shall be retained by Texas Regional until the
earlier of (i) such time as the shareholder relinquishes his, her or its right
of dissent, at which time the provisions of section 1.2.3 shall apply, except
that the time for delivery of such Texas Regional share certificate shall be
extended to a reasonable period of time following the date of relinquishment of
such dissenters' rights; or (ii) the time of settlement or judicial or other
resolution of such shareholder's dissenters' rights action, at which time Texas
Regional's obligation to issue or deliver shares to such shareholder shall cease
and be of no further force or effect.

     1.2.4.  Any dividends or other amounts payable to shareholders who
surrender their share certificates after the date of Closing shall not be
payable until surrender of the shareholder's TB&T Bancshares share certificate,
nor shall any such amounts bear interest attributable to periods either before
or after the date of Closing.

     1.3.  CLOSING.  Each of TB&T Bancshares and Texas Regional will use
reasonable efforts to close the transactions herein described on or before
January 10, 1998, provided that the conditions to closing as herein described

          1.3.4.  If the transactions contemplated by this Agreement are being
     contested in any legal proceeding and Texas Regional, pursuant to Section

     proceeding has been brought to a conclusion favorable, in the judgment of
     Texas Regional, to the consummation of the transactions contemplated
     hereby; or

                                      A-3

          1.3.5.  Such other date as TB&T Bancshares and Texas Regional may
     select by mutual agreement.

The Closing shall take place at the offices of Texas Regional, Kerria Plaza,

     1.5.  EFFECT OF MERGER.  As a result of the merger, TB&T Bancshares's
assets and business, including ownership of all of the capital stock of TB&T,

encumbrances.

     1.6.  BANK MERGER.  TB&T Bancshares shall take, in advance of the Effective

Agreement of Merger, any requested certificates of officers, and such other
documents as may be required to cause such merger to become effective in a
timely manner.

and TB&T Bancshares shall execute and deliver the Holdback Escrow Agreement in
the form attached to this Agreement as SCHEDULE 1.7, pursuant to which the

referred to as the "Special Claims", which term shall have the meaning
assigned to it in the Holdback Escrow Agreement).

               REPRESENTATIONS AND WARRANTIES OF TB&T BANCSHARES

     TB&T Bancshares represents and warrants to, and covenants and agrees with,
Texas Regional as follows:

     2.1.  ORGANIZATION AND OPERATION OF TB&T BANCSHARES.  TB&T Bancshares is a
Texas corporation, duly organized, validly existing and in good standing under
the laws of the state of Texas, and has full power and authority (including all

Bancshares is its ownership and operation of its subsidiary, TB&T. TB&T
Bancshares has no liabilities, liquidated or unliquidated, fixed or contingent,
and has no assets other than its ownership of all of the capital stock of TB&T.
Without limiting the generality of the foregoing, TB&T Bancshares is

     2.2.  ORGANIZATION AND OPERATION OF TB&T.  TB&T 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. TB&T is
in good standing under the laws of the state of Texas. TB&T operates only out of
its main bank facility and has no branch facilities, nor does TB&T have any
application pending for operation of a branch facility. True and complete copies
of the Articles of Association and Bylaws of TB&T, as amended to date, have been

belief of TB&T Bancshares, all books and records related to the business of TB&T
are true, correct and complete. TB&T's banking and other business activities are
in full compliance with sound banking practices and applicable provisions of
law, including the Texas Banking Code, the Federal Deposit Insurance Act, the
Federal Reserve Act and applicable regulations. Except as disclosed in SCHEDULE
2.2, TB&T has no subsidiaries or affiliates, owns no voting securities of any
other corporation, and is not a member of any joint venture or partnership.

     2.3.  CAPITALIZATION AND OWNERSHIP.  The authorized capital stock of TB&T
Bancshares consists of 2,000,000 shares of common stock, par value $1.00 per

all of which have been validly issued and outstanding, are fully paid,
nonassessable, and are owned beneficially and of record by the persons named in
the shareholder list previously delivered by TB&T Bancshares to Texas Regional.
The Shares have not been issued in violation of the preemptive rights of any

capital stock, par value $7.50 per share, all of which are duly authorized,
validly issued and outstanding, fully paid, nonassessable, and are owned
beneficially and of record by TB&T Bancshares. There are no outstanding options,
warrants, conversion rights, calls or commitments of any kind obligating TB&T
Bancshares or TB&T to issue, directly or indirectly, additional shares of
capital stock, and no authorization therefor has been given. Neither TB&T
Bancshares nor TB&T has any outstanding commitment or obligation to repurchase,
reacquire or redeem any of its outstanding capital stock.

     2.4.  FINANCIAL STATEMENTS AND RECORDS.

     2.4.1.  TB&T Bancshares has delivered to Texas Regional (i) the compiled
consolidated balance sheet of TB&T Bancshares and its subsidiaries as of
December 31, 1996, 1995 and 1994 (the "Balance Sheet"), and the related
compiled consolidated statements of income, changes in stockholders' equity and
changes in financial position for the years then ended, as compiled by the
independent accountant of TB&T Bancshares, accompanied by the compilation report
thereon of the independent certified public accountant who compiled such
statements. Except to the extent qualified by the report of the independent
accountant thereon, and except for certain disclosures omitted therefrom as
described or disclosed in the independent accountant's report, these financial
statements fairly present the financial position of TB&T Bancshares and its
subsidiaries as of the dates thereof and the results of its operations for the
periods indicated in conformity with generally accepted accounting principles
applied on a consistent basis. To the best knowledge of TB&T Bancshares, except
as qualified by the independent accountant's compilation report referred to
herein, the compiled consolidated financial statements of TB&T Bancshares and
its subsidiaries have been prepared in accordance with generally accepted
accounting principles. In addition, TB&T Bancshares has delivered to Texas
Regional its unaudited parent company only balance sheets and regulatory reports
of condition of TB&T Bancshares as of September 30, 1997, and its unaudited bank
only balance sheets and regulatory reports of condition of TB&T as of September
30, 1997 (collectively, such balance sheets are

                                      A-5
<PAGE>
hereafter sometimes called the "TB&T Bancshares Balance Sheet" and the "TB&T
Balance Sheet", respectively) and the related unaudited statements of income,
changes in stockholders' equity and changes in financial position for the
nine-month period then ended. In the opinion of the management of TB&T
Bancshares, these financial statements also fairly present the financial
position of TB&T Bancshares and TB&T as of the date thereof and the results of
their respective operations for the period indicated in conformity with
generally accepted accounting principles applied on a consistent basis. All of
the financial statements described in this paragraph are collectively referred
to hereinafter as the "TB&T Bancshares Financial Statements." Except as
described in SCHEDULE 2.4.1, the TB&T Bancshares Financial Statements do not, as
of the dates thereof, include any material assets or omit to state any material
liability, absolute or contingent, or other fact, 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, except as described in SCHEDULE 2.4.1, TB&T Bancshares
specifically represents to Texas Regional that TB&T Bancshares and its
subsidiaries have no liabilities, either accrued, contingent or otherwise,
which, individually or in the aggregate, are material, which have not been
reflected in the TB&T Bancshares Financial Statements (including the TB&T
Bancshares Balance Sheet and the TB&T Balance Sheet) or which have been incurred
in the ordinary course of business since the date of the TB&T Bancshares Balance
Sheet and the TB&T Balance Sheet. As of the time of Closing, any material
liabilities, accrued, contingent or otherwise, which have been incurred since
June 30, 1997, will have been fully disclosed to Texas Regional.

     2.4.2.  To the best knowledge and belief of TB&T Bancshares, except as
described in SCHEDULE 2.4.1, within the past five (5) years there have not been
any material changes in the financial condition, results of operations, business
or prospects of TB&T Bancshares and its subsidiaries, 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 TB&T Bancshares or its subsidiaries.

     2.4.3.  The books and records of TB&T Bancshares and its subsidiaries
reflect the transactions to which they are or were a party or by which their
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 with generally accepted accounting principles consistently applied. As
of the date hereof and as of the Closing, all of the minute books of TB&T
Bancshares and its subsidiaries are and will be complete, accurate and current.

     2.4.4.  TB&T and TB&T Bancshares have no trust business.

     2.5.  LOANS.

     2.5.1.  All loans included in the assets of TB&T Bancshares and its
subsidiaries, including specifically TB&T, and all commitments to make loans
(which includes leasing transactions and off balance sheet lending transactions
such as letters of credit and which constitutes all of the lending business of
TB&T Bancshares), have been made in the ordinary course of business of TB&T
Bancshares and, other than those loans that have been identified on the problem
loan list delivered to Texas Regional prior to or contemporaneously with the
execution hereof (which problem loan list has been marked for identification by
Texas Regional and TB&T Bancshares), such loans do not present more than the
normal risk of uncollectibility or other unfavorable features. TB&T Bancshares
will provide an updated problem loan list at the time of Closing.

     2.5.2.  All loans to directors, officers and beneficial owners of 5% or
more of the outstanding capital stock of TB&T Bancshares and loans to any person
or company related to or affiliated with any such person, are listed on the
related party transaction list provided to Texas Regional by TB&T Bancshares
(and marked for identification by Texas Regional and TB&T Bancshares), which
listing is herein called the "Related Party Transaction List". The loans
listed on the Related Party Transaction List do not present more than the normal
risk of uncollectibility or other unfavorable features.

                                      A-6
<PAGE>
     2.5.3.  The reserves for loan losses of TB&T (which constitute the total
reserves of TB&T Bancshares) have been calculated in accordance with all
applicable rules and regulations. In the reasonable opinion of the management,
officers and directors of TB&T Bancshares, the reserve for loan losses shown on
the TB&T Bancshares Balance Sheet is adequate in all respects to provide for all
losses on loans outstanding as of the date of the TB&T Bancshares Balance Sheet.

     2.6.  PROPERTIES.  Subject to reservations and exceptions shown on title
opinions or title policies delivered to Texas Regional (and marked for
identification by Texas Regional and TB&T Bancshares), TB&T Bancshares and its
subsidiaries, including TB&T, have good and marketable title to all assets and
properties, whether real or personal, tangible or intangible, which they purport
to own, including without limitation, all assets and properties reflected on the
TB&T Bancshares Balance Sheet or acquired subsequent thereto (except to the
extent such assets and properties have been disposed of in the ordinary course
of business since the date of the TB&T Bancshares Balance Sheet), subject to no
liens, mortgages, security interests, encumbrances, easements, title
imperfections, or charges of any kind except (i) as noted in the TB&T Bancshares
Balance Sheet or the notes to the TB&T Bancshares Financial Statements, (ii)
statutory liens not yet delinquent, (iii) security interests granted incident to
borrowings by TB&T 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 TB&T Bancshares. All improvements,
buildings and structures located on real estate owned by TB&T Bancshares and its
subsidiaries, and the use by TB&T Bancshares and its subsidiaries of such real
estate, together with such improvements, buildings and structures, in the manner
heretofore and currently used by TB&T Bancshares and its subsidiaries, 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. All such improvements, buildings and structures located on real estate
owned by TB&T Bancshares and its subsidiaries, and all of the material, tangible
personal property owned by TB&T Bancshares and its subsidiaries, are in good
operating condition and repair, reasonable wear and tear excepted. Listed on
SCHEDULE 2.6 are all policies of title insurance covering such properties.

     2.7.  ENVIRONMENTAL MATTERS.  To the best knowledge and belief of TB&T
Bancshares, neither any Environmental Hazards nor any Hazardous Materials
Contamination exist on any real property owned or used by TB&T Bancshares and
its subsidiaries, including TB&T (including any owned by and used in connection
with the business of TB&T and any foreclosed properties owned by TB&T), or on
any real property used by TB&T in connection with the business of TB&T 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." 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;
(vii) radon gas; (viii) any solid waste or petroleum waste; and (ix) any other

notification of any federal, state or local governmental entity in its
collection, storage, treatment, or disposal or which is identified or classified
to be hazardous or toxic under applicable state or federal law or regulation or
the common law, or any other applicable laws. As used in this Agreement, the
term "Hazardous Materials Contamination" shall mean the contamination of the
improvements, facilities, soil, groundwater, air or other elements on or of the
Real Property by Hazardous Materials, or the contamination of the buildings,

                                      A-7
<PAGE>
facilities, soil, groundwater, air or other elements on or of any other property
as a result of Hazardous Materials at any time before the date of this Agreement
emanating from the Real Property.

     2.8.  LITIGATION.  Except as specifically disclosed in the Holdback Escrow
Agreement and the related Special Report to the Board of Directors of TB&T
Bancshares referred to therein (which Special Report has been marked for
identification by Texas Regional and TB&T Bancshares), no claims have been
asserted and no relief has been sought against TB&T Bancshares or any of its
subsidiaries, including TB&T, in any pending litigation or governmental
proceedings or otherwise which might result in a judgment, decree or order
having a material adverse effect on the financial condition, results of
operations, business or prospects of TB&T Bancshares or any of its subsidiaries.
To the best knowledge and belief of TB&T Bancshares, TB&T Bancshares and its
subsidiaries have complied with, and are presently in compliance with, all laws
and regulations pertaining to consumer credit and truth in lending. The
management of TB&T Bancshares and its subsidiaries is not aware of any material
violation by TB&T Bancshares or any subsidiary of TB&T Bancshares of any of the
foregoing. To the best knowledge and belief of TB&T Bancshares, TB&T Bancshares
and its subsidiaries are in substantial compliance with all other laws, all
rules and regulations of governmental agencies and authorities and any
judgments, orders or decrees which by their terms apply to any of them. All
permits, concessions, grants, franchises, licenses and other governmental
authorizations and approvals necessary for the conduct of the business of TB&T
Bancshares and its subsidiaries have been duly obtained and are in full force
and effect, and there are no proceedings pending or, to TB&T Bancshares' and its
subsidiaries' knowledge, threatened which may result in the revocation,
cancellation, suspension or adverse modification of any thereof. The
consummation of the transactions contemplated hereby will not result in any such
revocation, cancellation, suspension or modification.

     2.9.  TAXES.  TB&T Bancshares and its subsidiaries have filed with the
appropriate governmental agencies all federal, state and local income,
franchise, excise, real and personal property and other tax returns and reports
which are required to be filed, and neither TB&T Bancshares nor any subsidiary
of TB&T Bancshares is delinquent in the payment of any taxes shown on such
returns or reports. TB&T Bancshares has no examination pending by the Internal
Revenue Service, the Texas Comptroller of Public Accounts, or any other taxing
authority, nor has TB&T Bancshares been notified of any proposed examination.
There are included in the TB&T Bancshares Balance Sheet, or reflected in the
Notes to the TB&T Bancshares Financial Statements, reserves adequate in the
reasonable opinion of management for the payment of all accrued but unpaid
federal, state and local taxes of TB&T Bancshares and its subsidiaries,
including all income, franchise, ad valorem and other taxes, and all interest
and penalties, whether or not disputed, for the nine-month period ended
September 30, 1997, for the year ended December 31, 1996, and for all fiscal
years prior thereto. Neither TB&T Bancshares nor any subsidiary of TB&T
Bancshares has executed or filed with the Internal Revenue Service, the
Comptroller of Public Accounts of the State of Texas or any other taxing
authority any agreement extending the period for assessment and collection of
any tax, nor is TB&T Bancshares nor any subsidiary a party to any action or
proceeding by any governmental authority for assessment or collection of taxes,
nor has any claim for assessment or collection of taxes been asserted against
any of them. Neither TB&T Bancshares nor any of its subsidiaries has filed a
consent pursuant to Section 341(f) of the Internal Revenue Code or otherwise.

     2.10.  CONTRACTS.  Except as set forth in SCHEDULE 2.10, neither TB&T

less than $400,000 in any one transaction and $400,000 in the aggregate; (vii)
agreements to which any director, officer or holder of 5% or more of the
outstanding capital stock of TB&T Bancshares, or any

                                      A-8
<PAGE>
person or company related to or affiliated with any such person, is a party;
(viii) contracts relating to the purchase or sale of financial or other futures,

all material respects performed all obligations required to be performed by them
to date. Neither TB&T Bancshares nor any of its subsidiaries is in default, and
no event has occurred which, with notice or the lapse of time or action by a
third party, could result in a default by TB&T Bancshares or any of its
subsidiaries, (a) under any outstanding indenture, mortgage, contract, lease or
other agreement to which it is a party or by which it is bound; (b) under any
provision of its Articles of Incorporation or Bylaws or other organizational

condition, results of operations, business or prospects of TB&T Bancshares and
its subsidiaries; or (c) under any agreement with federal or state regulatory
authorities. TB&T Bancshares and its subsidiaries have not granted any power of
attorney, except routine powers of attorney relating to representation before

such other party's directors, officers and each person who "controls" such

                                      A-12
<PAGE>
"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:

          4.3.1.  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

          4.3.2.  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.

     4.4.  LEGAL AND OTHER COSTS.  The indemnification obligations contained
herein shall expressly include the obligation of the Indemnifying Party to

liabilities or actions whether or not resulting in any liability.

     4.5.  NOTICES AND PARTICIPATION RIGHTS.  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.

     4.6.  SURVIVAL AND ARBITRATION.  The indemnity agreement contained in this
Article 4 shall survive any investigation made by or on behalf of any
Indemnified Party but shall not survive the closing of the transactions
described in this Agreement. In the event of any disputed claim for
indemnification under this Article 4, the claim shall be submitted to binding
arbitration by the party or parties claiming indemnification and the party or
parties against whom the indemnification obligation is claimed, each of whom
shall select a qualified, commercial arbitrator. The two arbitrators so selected
shall in turn select a third arbitrator who shall sit with the two arbitrators
selected by the parties as an arbitration panel. The arbitrators shall in each
case be qualified in arbitrating matters such as the disputed claim for
indemnification, and they shall arbitrate the dispute in accordance with
applicable rules of the American Arbitration Association. Any ruling rendered by
the arbitrators shall be final, binding and conclusive.

agrees to cooperate (and to cause its subsidiaries to cooperate) with any
reasonable request of Texas Regional related to site assessment or site review
related to any environmental matter or investigation, including making available
such personnel of TB&T Bancshares and TB&T as Texas Regional may reasonably
request. At Texas Regional's discretion, Texas Regional 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 TB&T
Bancshares and its subsidiaries 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 Regional may deem reasonably
necessary. Any and all costs of third parties associated with obtaining such
information shall be borne by Texas Regional. In the event Texas Regional
arranges for and causes such tests to be conducted, and if such tests indicate
the presence of Hazardous Material Contamination, Texas Regional shall be
entitled to terminate this Agreement by written notice to TB&T Bancshares
without further liability or obligation.

shareholders of TB&T Bancshares:

          Frank D. Yturria, James John, Bob A. Austin, Julius Collins and Dwayne
     Tyner (individually and as trustee)

     (collectively, the "Affiliate Shareholders"), all of whom are officers,
directors or shareholders owning in excess of 10% of the outstanding capital
stock of TB&T Bancshares, have joined into the execution of this Agreement to
acknowledge and agree to the following:

          a.  The undersigned Affiliate Shareholders acknowledge that Texas
     Regional's offer to acquire TB&T Bancshares on the terms and conditions
     described in this Agreement is predicated upon the transactions being
     accounted for as pooling of interests for generally accepted accounting
     purposes.

          b.  It is a requirement of pooling of interests accounting that the
     affiliates of the companies being merged agree to certain restrictions on
     their stock. Each of the undersigned Affiliate Shareholders is an affiliate
     of TB&T Bancshares for purposes of these rules.

          c.  Each of the undersigned Affiliate Shareholders agrees that he will
     not sell, pledge, transfer or otherwise dispose of any shares of TB&T
     Bancshares stock within thirty (30) days prior to the Effective Time. Each
     Affiliate Shareholder further agrees that until publication of financial
     results covering at least 30 days of post-merger combined operations of
     TB&T Bancshares and Texas Regional, he will not sell, pledge, transfer or
     otherwise dispose of any shares of Texas Regional stock to be acquired by
     him in the merger transaction, unless such Affiliate Shareholder first
     obtains the consent of Texas Regional. The undersigned further agrees that
     he will not sell, pledge, transfer or otherwise dispose of any shares of
     Texas Regional stock acquired by him in the merger transaction except in a
     manner that is consistent with any additional requirements for Texas
     Regional accounting for the merger as a pooling of interests, including
     without limitation any requirements imposed by applicable provisions of the
     Securities Act of 1933, the Securities Exchange Act of 1934 and rules and
     regulations promulgated thereunder. Each Affiliate Shareholder agrees that
     a restrictive legend to the foregoing effect may be placed on any
     certificate evidencing shares of Texas Regional stock to be issued in
     connection with the merger transaction. Texas Regional will remove the
     restrictive legend from any certificates evidencing shares subject hereto
     promptly following the expiration of the transfer restrictions described in
     this paragraph.

          d.  Each Affiliate Shareholder further acknowledges and agrees that he
     will be subject to Rule 145 promulgated by the SEC under the Securities Act
     of 1933, and he agrees not to transfer any Texas Regional stock received by
     him in the Merger except in compliance with applicable provisions of the
     Securities Act, the Securities Exchange Act and applicable rules and
     regulations promulgated thereunder.

                           HOLDBACK ESCROW AGREEMENT

     This Holdback Escrow Agreement (the "Holdback Escrow Agreement") is made
and entered into as of the       day of             , 199  by and between Texas
Regional Bancshares, Inc., a Texas corporation ("Texas Regional"), TB&T
Bancshares, Inc. ("TB&T Bancshares"), and Texas State Bank ("Escrow Agent").

     Glen E. Roney joins into the execution hereof to evidence his agreement to
accept appointment as "Special Agent" for Texas Regional, and Frank D. Yturria
joins into the execution hereof to evidence his agreement to accept appointment
as "Special Agent" for the shareholders of TB&T Bancshares listed on Exhibit A
(herein sometimes called the "TB&T Bancshares shareholders"). Texas Regional
may at any time appoint a substitute for Glen E. Roney as Special Agent for
Texas Regional, which appointment shall be effective upon delivery of notice
thereof to both the Escrow Agent and the Special Agent for the TB&T Bancshares
shareholders. The TB&T Bancshares shareholders may, by action of a majority in
interest of the TB&T Bancshares shareholders, at any time appoint a substitute
for Frank D. Yturria as Special Agent for the TB&T Bancshares shareholders,
which appointment shall be effective upon delivery of notice thereof to both the
Escrow Agent and Texas Regional.

     WHEREAS, Texas Regional and TB&T Bancshares have entered into an Agreement
and Plan of Reorganization pursuant to which TB&T Bancshares is, of even date
herewith, being merged with and into Texas Regional Delaware, Inc., a Delaware
corporation wholly-owned by Texas Regional; and

     WHEREAS, the Agreement and Plan of Reorganization by and between Texas
Regional and TB&T Bancshares provides for the escrow of a portion of the shares
of Texas Regional Bancshares, Inc. Class A Voting Common Stock, and dividends on
such shares (or at the election of individual shareholders of TB&T Bancshares,
certain other assets) in the event that Texas Regional and its subsidiaries
sustain certain losses more particularly described herein;

     NOW, THEREFORE, in consideration of the foregoing and of the covenants and
agreements contained in the Agreement and Plan of Reorganization, effective as
of immediately prior to the merger of TB&T Bancshares with and into Texas
Regional Delaware, Inc., Texas Regional, TB&T Bancshares and the Escrow Agent
hereby agree as follows:

     1.  ESCROW SHARES.  Of even date herewith, Texas Regional is depositing
into escrow with the Escrow Agent, as required by the terms of the Agreement and
Plan of Reorganization, an aggregate of
shares of Texas Regional Class A Voting Common Stock (the "Escrow Stock"). At
all times during which any shares of Escrow Stock are held pursuant to this
Holdback Escrow Agreement, the TB&T Bancshares shareholders shall be treated as
the beneficial owners of the Escrow Stock, and as the beneficial owners of any
dividends thereon and any other proceeds thereof, in each case subject to the
rights of Texas Regional under this Holdback Escrow Agreement to require that
such shares of Escrow Stock (and any related dividends or other proceeds
thereof) be returned to Texas Regional in payment of Losses and Damages (as
herein defined) attributable to one or more Special Claims (as herein defined).
Each TB&T Bancshares shareholder shall be entitled to vote his or her allocated
shares of Escrow Stock in any action requiring a vote of the shareholders of
Texas Regional, unless and until such time as any of such shares of Escrow Stock
are actually distributed to Texas Regional in valid payment of Losses and
Damages attributable to a Special Claim.

     2.  SPECIAL CLAIMS.  Texas Regional shall be entitled to require that
Escrow Stock be distributed to Texas Regional pursuant to this Holdback Escrow
Agreement, in the event that Texas Regional or any subsidiary of Texas Regional
(including Texas State Bank) is required to pay any amount of Losses and Damages
arising out of or directly or indirectly related to any of the following:

          a.  Any liability or obligation (including any incurred in the defense
     of any claim) which arises out of the activities of Paula G. Gonzalez, a
     former employee of TB&T, identified in a Special Report

                                      A-26
<PAGE>
     to the Board of Directors of TB&T dated April 15, 1997, a copy of which has
     been provided to Texas Regional and marked for identification by Texas
     Regional and TB&T Bancshares;

          b.  Any liability or obligation (including any incurred in the defense
     of any claim) which arises in connection with a lawsuit filed as Cause
     Number 97-06-04585-E and currently pending in the 357th District Court of
     Cameron County, Texas, styled RAFAEL POZOS, SR. V. TEXAS BANK & TRUST AND
     PAULA G. GONZALEZ;

          c.  Any liability or obligation (including any incurred in the defense
     of any claim) which arises out of a claim by Rebecca Vera relating to an
     alleged deposit and allegedly unauthorized transfers and withdrawals from
     Ms. Vera's account, including those described in a demand letter written to
     TB&T on behalf of Ms. Vera, dated May 23, 1997, a copy of which has been
     provided to Texas Regional and marked for identification by Texas Regional
     and TB&T Bancshares; and

          d.  Any liability or obligation (including any incurred in the defense
     of any claim) which arises out of certain unaccounted for Certificates of
     Deposit bearing the numbers indicated in the Missing Certificates of
     Deposit Schedule, a copy of which has been provided to Texas Regional and
     marked for identification by Texas Regional and TB&T Bancshares.

     The foregoing are herein collectively referred to as the "Special
Claims." For purposes hereof, the term "Losses and Damages" shall mean any
and all amounts which are paid to claimants as a result of liquidation of
judgments or settlements and all out-of-pocket expenses, including, but not
necessarily limited to, reasonable attorney's fees, investigation costs,
accounting costs, court costs and other expenses. The fees and costs included
within Losses and Damages specifically includes the amounts of attorney's fees
and expenses of the counsel selected by the Special Agent for the TB&T
Bancshares shareholders and the counsel selected by the Special Agent for Texas
Regional pursuant to section 9 hereof.

     3.  DISTRIBUTION PROCEDURE.  In the event Texas Regional, or its
subsidiaries, including specifically but without limitation, Texas Regional
Delaware, Inc. and Texas State Bank, in each case as successor-in-interest to
the mergers, respectively, with TB&T Bancshares and Texas Bank and Trust of
Brownsville, sustain Losses and Damages arising out of or related to Special
Claims, such Losses and Damages shall be paid as follows:

          a.  Until such time as aggregate Losses and Damages paid by return to
     Texas Regional of Escrow Stock held pursuant to this Holdback Escrow
     Agreement exceed $500,000.00, an amount equal to 90% of such Losses and
     Damages shall be paid to Texas Regional by return of Escrow Stock to Texas
     Regional.

          b.  In the event the aggregate amount of Losses and Damages paid by
     distribution to Texas Regional of Escrow Stock held pursuant to this
     Holdback Escrow Agreement are in excess of $500,000.00, an amount equal to
     50% of each Special Claim thereafter paid shall be paid to Texas Regional
     by return of Escrow Stock to Texas Regional from shares held pursuant to
     this Holdback Escrow Agreement, until either this Holdback Escrow Agreement
     is terminated or all of the Escrow Stock held pursuant to this Holdback
     Escrow Agreement has been returned.

          c.  Nothing in this Holdback Escrow Agreement shall require any
     officer, director, TB&T Bancshares shareholder or other person to pay any
     Special Claim, other than by return or other distribution of Escrow Stock
     held by pursuant to this Holdback Escrow Agreement.

     The number of shares of Escrow Stock returned shall equal the amount of the
Losses and Damages being paid by return of Escrow Stock, divided by $30.025. In
the event of any return of Escrow Stock to Texas Regional pursuant to this
Holdback Escrow Agreement, such Escrow Stock shall be canceled as if never
issued.

     4.  DIVIDENDS OR OTHER PROCEEDS.  In the event of any declaration of
dividends or other proceeds payable with respect to the Escrow Stock held
pursuant to this Holdback Escrow Agreement, such dividends and other proceeds
shall be retained in escrow pursuant to this Holdback Escrow Agreement, in an
interest bearing account or accounts, until such time as the shares of Escrow
Stock with respect to which

                                      A-27
<PAGE>
such dividends or other proceeds were paid are either (i) returned to Texas
Regional in satisfaction of one or more Special Claims, in which event the
dividends, other proceeds and the earnings thereon shall be canceled as if never
paid or accrued; or (ii) distributed to the TB&T Bancshares shareholders listed
in Exhibit A, at which time the dividends or other proceeds attributable to
shares distributed to TB&T Bancshares shareholders and the earnings attributable
to such distributed dividends or other proceeds shall likewise be distributed to
the TB&T Bancshares shareholders.

     5.  TERMINATION.  The escrow arrangement herein described shall be
terminated, and any Escrow Stock and undisbursed dividends and other proceeds
and any earnings then remaining in the escrow account shall be distributed to
the TB&T Bancshares shareholders listed in Exhibit A, in the percentages
indicated in Exhibit A on the date upon which all Special Claims have been fully
and completely resolved, in the joint discretion of the Special Agent on behalf
of Texas Regional and the Special Agent on behalf of the TB&T Bancshares
shareholders.

     This Holdback Escrow Agreement shall automatically terminate upon the
return or distribution of all of the assets held in accordance with the terms
hereof, or if not sooner terminated shall automatically terminate and all such
assets shall be returned or distributed to the beneficiaries entitled thereto,
upon the expiration of twenty-one years following the date of execution hereof.

     6.  SPECIAL SECOND ANNIVERSARY DISTRIBUTION.  If the Special Agents have
not jointly agreed that all Special Claims have been fully and completely
resolved on or prior to the second anniversary of the date of execution hereof,
the escrow relationship created by this Holdback Escrow Agreement shall continue
until the date that all Special Claims are fully and finally resolved; provided,
however, that the only Escrow Stock held pursuant to this Holdback Escrow
Agreement subsequent to the second anniversary of the date of execution hereof
shall be an amount reasonably determined by joint decision of the Special Agent
for Texas Regional and the Special Agent for the TB&T Bancshares shareholders,
to approximate the amount of Losses and Damages reasonably anticipated to arise
out of any Special Claims pending or threatened as of the second anniversary,
which amount shall continue to be held pursuant to this Holdback Escrow
Agreement on behalf of the shareholders listed in Exhibit A until the final
resolution of all such pending Special Claims. Any Escrow Stock (and all
dividends and other proceeds, and earnings thereon, with respect to such shares
of Escrow Stock) held pursuant to this Holdback Escrow Agreement in excess of
such agreed amount shall be distributed to the former TB&T Bancshares
shareholders as their respective interests may appear according to the records
kept by the Escrow Agent pursuant to section 7 hereof.

     7.  RECORDKEEPING; PROPORTIONATE FUNDING.  The Escrow Agent shall maintain
appropriate records indicating, initially, the number of shares of Escrow Stock
allocated to the account of each TB&T Bancshares shareholder and, thereafter,
the reduction in number of shares of Escrow Stock as a result of distributions
to Texas Regional in payment of Special Claims and any reduction as a result of
distribution of Escrow Stock to the TB&T Bancshares shareholder. Any Special
Claim paid to Texas Regional pursuant to this Holdback Escrow Agreement shall be
funded by the Escrow Agent on a pro rata basis from all TB&T Bancshares
shareholder accounts held pursuant to this Holdback Escrow Agreement so that, as
nearly as possible, the Special Claims shall be funded from accounts maintained
by the Escrow Agent for the TB&T Bancshares shareholders in the percentages
indicated in Exhibit A. The Escrow Agent shall likewise maintain records
indicating the dividends and other proceeds allocated to each shareholder, any
earnings thereon, and any reductions resulting from distributions of Escrow
Stock to Texas Regional in payment of Losses and Damages and any distributions
of Escrow Stock to TB&T Bancshares shareholders in accordance with this Holdback
Escrow Agreement. Not less often than annually, the Escrow Agent shall provide a
report to the Special Agent for the TB&T Bancshares shareholders of the number
of shares of Escrow Stock and the amount of dividends and other proceeds, and
earnings on dividends, held for the benefit of each former TB&T Bancshares
shareholder.

     8.  JOINT ACTION OF SPECIAL AGENTS.  Notwithstanding anything herein to the
contrary, no Escrow Stock, accumulated dividends or other proceeds or other
assets shall be distributed to Texas Regional under or pursuant to this Holdback
Escrow Agreement, in payment of Losses and Damages or otherwise, unless such
distribution is either (a) approved by Frank D. Yturria or his successor as
Special Agent on behalf of

                                      A-28
<PAGE>
the shareholders of TB&T Bancshares; or (b) determined by binding arbitration as
herein provided to be a proper and lawful disbursement of such assets from the
escrow. Notwithstanding anything herein to the contrary, no Escrow Stock,
accumulated dividends or other proceeds or other assets shall be distributed to
the TB&T Bancshares shareholders under or pursuant to this Holdback Escrow
Agreement, unless such distribution is either (a) approved by Glen E. Roney or
his successor as Special Agent on behalf of Texas Regional; or (b) determined by
binding arbitration as herein provided to be a proper and lawful disbursement of
such assets from the escrow.

     9.  ACCESS TO INFORMATION; APPOINTMENT OF COUNSEL.  During the term of this
Holdback Escrow Agreement, the TB&T Bancshares shareholders shall have complete
access to all information relating to the Special Claims, and the progress of
Texas Regional in resolving any Special Claims. The TB&T Bancshares
shareholders, acting by and through the Special Agent for the TB&T Bancshares
shareholders, and Texas Regional, acting by and through the Special Agent for
Texas Regional, shall each be entitled to select an attorney to participate, in
an "of counsel" capacity, in any judicial proceeding related to a Special
Claim. The attorneys' fees, costs and expenses of any such counsel selected by
the Special Agent for the TB&T Bancshares shareholders and any such counsel
selected by the Special Agent for Texas Regional shall be paid as part of the
Losses and Damages reimbursed pursuant to this Holdback Escrow Agreement.

     10.  RELIANCE ON SPECIAL AGENT AND NOTICES.  Each TB&T Bancshares
shareholder shall be deemed for all purposes to have appointed Frank D. Yturria
or his successor as Special Agent on behalf of the TB&T Bancshares shareholders
to act as agent on their behalf with respect to any notices, receipts or other
acts, including settlement of any dispute or other matter arising out of this
Holdback Escrow Agreement, and Texas Regional and any other party shall be
entitled to rely upon the acts of such Special Agent in taking any action
hereunder. Texas Regional shall be deemed for all purposes to have appointed
Glen E. Roney or his successor as Special Agent on behalf of Texas Regional to
act as agent on its behalf with respect to any notices, receipts or other acts,
including settlement of any dispute or other matter arising out of this Holdback
Escrow Agreement, and the TB&T Bancshares shareholders and any other party shall
be entitled to rely upon the acts of such Special Agent in taking any action
hereunder.

                  PROVISIONS OF TEXAS BUSINESS CORPORATION ACT
                 RELATING TO RIGHTS OF DISSENTING SHAREHOLDERS

ART. 5.12. PROCEDURE FOR DISSENT BY SHAREHOLDERS AS TO SAID CORPORATE ACTIONS

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

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

          (b)  With respect to proposed corporate action that is approved
     pursuant to Section A of Article 9.10 of this Act, the corporation, in the
     case of action other than a merger, and the surviving or new corporation
     (foreign or domestic) or other entity that is liable to discharge the
     shareholder's right of dissent, in the case of a merger, shall, within ten
     (10) days after the date the action is effected, mail to each shareholder
     of record as of the effective date of the action notice of the fact and
     date of the action and that the shareholder may exercise the shareholder's
     right to dissent from the action. The notice shall be accompanied by a cow
     of this Article and any articles or documents filed by the corporation with
     the Secretary of State to effect the action. If the shareholder shall not
     have consented to the taking of the action, the shareholder may, within
     twenty (20) days after the mailing of the notice, make written demand on
     the existing, surviving, or new corporation (foreign or domestic) or other
     entity, as the case may be, for payment of the fair value of the
     shareholder's shares. The fair value of the shares shall be the value
     thereof as of the date the written consent authorizing the action was
     delivered to the corporation pursuant to Section A of Article 9.10 of this
     Act, excluding any appreciation or depreciation in anticipation of the
     action. The demand shall state the number and class of shares owned by the
     dissenting shareholder and the fair value of the shares as estimated by the
     shareholder. Any shareholder failing to make demand within the twenty (20)
     day period shall be bound by the action.

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

                                      B-1
<PAGE>
     shareholder that the shareholder agrees to accept that amount and, in the
     case of shares represented by certificates, upon the surrender of the
     certificates duly endorsed.

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

     B.  If, within the period of sixty (60) days after the, date on which the
corporate action was effected, the shareholder and the existing, surviving, or
new corporation (foreign or domestic) or other entity, as the case may be, do
not so agree, then the shareholder or the corporation (foreign or domestic) or
other entity may, within sixty (60) days after the expiration of the sixty (60)
day period, file a petition in any court of competent jurisdiction in the county
in which the principal office of the domestic corporation is located, asking for
a finding and determination of the fair value of the shareholder's shares. Upon
the filing of any such petition by the shareholder, service of a copy thereof
shall be made upon the corporation (foreign or domestic) or other entity, which
shall, within ten (10) days after service, file in the office of the clerk of
the court in which the petition was filed a list containing the names and
addresses of all shareholders of the domestic corporation who have demanded
payment for their shares and with whom agreements as to the value of their
shares have not been reached by the corporation (foreign or domestic) or other
entity. If the petition shall be filed by the corporation (foreign or domestic)
or other entity, the petition shall be accompanied by such a list. The clerk of
the court shall give notice of the time and place fixed for the hearing of the
petition by registered mail to the corporation (foreign or domestic) or other
entity and to the shareholders named on the list at the addresses therein
stated. The forms of the notices by mail shall be approved by the court. All
shareholders thus notified and the corporation (foreign or domestic) or other
entity shall thereafter be bound by the final judgment of the court.

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

     D.  The appraisers shall determine the fair value of the shares of the
shareholders adjudged by the court to be entitled to payment for their shares
and shall file their report of that value in the office of the clerk of the
court. Notice of the filing of the report shall be given by the clerk to the
parties in interest. The report shall be subject to exceptions to be heard
before the court both upon the law and the facts. The court shall by its
judgment determine the fair value of the shares of the shareholders entitled to
payment for their shares and shall direct the payment of that value by the
existing, surviving, or new corporation (foreign or domestic) or other entity,
together with interest thereon, beginning 91 days after the date on which the
applicable corporate action from which the shareholder elected to dissent was
effected to the date of such judgment, to the shareholders entitled to payment.
The judgment shall be payable to the holders of uncertificated shares
immediately but to the holders of shares represented by certificates only upon,
and simultaneously with, the surrender to the existing, surviving, (foreign or
domestic) or other entity, as the case may be, of duly endorsed certificates for
those shares. Upon payment of the judgment, the dissenting shareholders shall
cease to have any interest in those shares or in the corporation. The court
shall allow the appraisers a reasonable fee as court costs, and all court costs
shall be allotted between the parties in the manner that the court determines to
be fair and equitable.

                                      B-2
<PAGE>
     E.  Shares acquired by the existing, surviving, or new corporation (foreign
or domestic) or other entity, as the case may be, pursuant to the payment of the
agreed value of the shares or pursuant to payment of the judgment entered for
the value of the shares, as in this Article provided, shall, in the case of a
merger, be treated as provided in the plan of merger and, in all other cases,
may be held and disposed of by the corporation as in the case of other treasury
shares.

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

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

ART. 5.13. PROVISIONS AFFECTING REMEDIES OF DISSENTING SHAREHOLDERS

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

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

     C.  Any shareholder who has demanded payment for his shares in accordance
with either Article 5.12 or 5.16 of this Act may withdraw such demand at any
time before payment for his shares or before any petition has been filed
pursuant to Article 5.12 or 5.16 of this Act asking for a finding and
determination of the fair value of such shares, but no such demand may be
withdrawn after such payment has been made or, unless the corporation shall
consent thereto, after any such petition has been filed. If, however, such
demand shall be withdrawn as hereinbefore provided, or if pursuant to Section B
of this Article the corporation shall terminate the shareholder's rights under
Article 5.12 or 5.16 of this Act, as the case may be, or if no petition asking
for a finding and determination of fair value of such shares by a court shall
have been filed within the time provided in Article 5.12 or 5.16 of this Act, as
the case may be, or if after the hearing of a petition filed pursuant to Article
5.12 or 5.16, the court shall determine that such shareholder is not entitled to
the relief provided by those articles, then, in any such case, such shareholder
and all persons claiming under him shall be conclusively presumed to have
approved and ratified the corporate action from which he dissented and shall be
bound thereby, the right of such shareholder to be paid the fair value of his
shares shall cease, and his status as a shareholder shall be restored without
prejudice to any corporate proceedings which may have been taken during the
interim, and such shareholder shall be entitled to receive any dividends or
other distributions made to shareholders in the interim.

          Re:  Texas Regional Bancshares, Inc.: Acquisition of
            TB&T Bancshares, Inc.

Dear Sir or Madam:

     You have requested the opinion of KPMG Peat Marwick LLP ("KPMG") as to
certain Federal income tax consequences to Texas Regional Bancshares, Inc.,
Texas Regional Delaware, Inc., Texas State Bank, TB&T Bancshares, Inc., Texas
Bank and Trust of Brownsville and the shareholders of TB&T Bancshares, Inc. with
respect to the proposed transaction described below. Our opinion is based solely

dated October 15, 1997 ("the Agreement") with respect to the two mergers
described below and information and representations provided to us as set forth

documents other than the Agreement which are necessary to effectuate the
transaction. We assume that all steps will be properly effectuated under the
applicable laws of the states of Texas and Delaware, and are consistent with the
information submitted to us.

     Further, in rendering our opinion, we are relying upon the Internal Revenue
Code of 1986 and Treasury Department regulations thereunder, as amended and in

or prospectively. Further, the opinion which is rendered should be considered
together with various risks set forth in the "CAVEAT" section of this letter.
Unless requested otherwise, we undertake no responsibility to update our opinion
in the event of any subsequent change in the foregoing.

                                     FACTS

     Texas Regional Bancshares, Inc. ("Texas Regional") is a Texas corporation
that is a bank holding company. Texas Regional is the common parent of an
affiliated group of corporations that file a consolidated federal income tax
return. The authorized capital of Texas Regional consists of 20 million shares
of Class A Voting Common Stock, par value $1.00 per share, of which 13,110,639
are issued and

                                      C-1
<PAGE>
outstanding. Texas Regional also has authorized 10 million shares of preferred
stock, none of which are issued or outstanding.

     Texas Regional Delaware, Inc. ("TRD") was incorporated in Delaware on
October 1, 1997, as a wholly-owned subsidiary of Texas Regional for the purpose
of facilitating the proposed transaction herein described. The authorized
capital of TRD consists of 3,000 shares of common stock of which 3,000 are
issued and outstanding.

     Texas State Bank ("Texas State Bank") is a Texas state banking
association and at the time of the merger, will be a wholly-owned subsidiary of
TRD. The authorized capital of Texas State Bank consists of 9 million shares of
common stock of which 9 million were issued and outstanding as of October 15,
1997.

     TB&T Bancshares, Inc. ("TB&T Bancshares") is a Texas corporation that is
a bank holding company. The authorized capital of TB&T Bancshares consists of
2,000,000 shares of $1.00 par value common stock of which 1,695,775 shares are
issued and outstanding.

     Texas Bank and Trust of Brownsville ("Texas Bank & Trust") is a Texas
state banking association engaged in the commercial banking business in Texas.
Texas Bank & Trust is a wholly-owned subsidiary of TB&T Bancshares. The
authorized capital of Texas Bank & Trust consists of 100,000 shares of $7.50 par
value common stock, all of which are issued and outstanding.

     The respective managements of Texas Regional and TB&T Bancshares believe
that a combination of their respective businesses will enable both companies to
grow and operate more efficiently.

                              PROPOSED TRANSACTION

     In order to accomplish the aforementioned goals, the following transaction
has been proposed:

          (1)  TB&T Bancshares will merge with and into TRD with TRD surviving,
     pursuant to the applicable laws of the states of Delaware and Texas. As a
     result of the merger, the shares of TB&T Bancshares common stock (other
     than any shareholder validly exercising dissenters' rights of appraisal)
     shall be automatically converted into 0.1522126 of a share of Texas
     Regional Class A Voting Common Stock ("Texas Regional Common Stock") for
     each share of TB&T Bancshares common stock. In addition, for each share of
     TB&T Bancshares common stock outstanding, 0.0294605 of a share of Texas
     Regional Common Stock will be deposited into an escrow to be either
     distributed to the shareholders of TB&T Bancshares or returned to Texas
     Regional for cancellation upon the occurrence of certain conditions.
     Fractional shares shall not be issued and any amount attributable to
     fractional shares shall be paid in cash. Amounts payable in respect of
     shareholders exercising dissenters' rights of appraisal shall be payable by
     TRD.

          (2)  As stated above, Texas Regional will transfer shares of its
     common stock to an escrow agent pursuant to the Holdback Escrow Agreement
     ("the Escrow Agreement"). The TB&T Bancshares shareholders will have the
     right to vote such shares. The reason for the escrow arrangement is to
     provide for a purchase price adjustment in the event that Texas Regional or
     any subsidiary of Texas Regional (including Texas State Bank) is required
     to pay any amount of losses or damages arising from certain claims against
     TB&T Bancshares or Texas Bank & Trust.

          (3)  Concurrently with or immediately after the merger of TB&T
     Bancshares into TRD, Texas Bank & Trust will merge with and into Texas
     State Bank, with Texas State Bank surviving, pursuant to the applicable
     laws of the state of Texas.

                                REPRESENTATIONS

     In connection with the proposed transaction, the following representations
have been made:

          (a)  The fair market value of the Texas Regional Common Stock to be
     received by the TB&T Bancshares shareholders will in each instance be
     approximately equal to the fair market value of the TB&T Bancshares common
     stock to be surrendered in exchange therefor.

                                      C-2
<PAGE>
          (b)  The managements of TB&T Bancshares and Texas Regional are not
     aware of any plan or intention on the part of the TB&T Bancshares
     shareholders to sell or otherwise dispose of a number of shares of Texas
     Regional Common Stock to be received in the proposed transaction that will
     reduce such shareholders' ownership to a number of shares having, in the
     aggregate, a value of less than 50 percent of the fair market value of the
     TB&T Bancshares common stock outstanding as of the effective date of the
     proposed transaction. Sales, redemptions, and other dispositions of TB&T
     Bancshares common stock (including payment of cash to dissenters and
     exchanges for cash in lieu of fractional shares of Texas Regional Common
     Stock) will be considered in determining whether there is a 50 percent
     continuing interest through stock ownership as of the effective date of the
     proposed transaction.

          (c)  TRD will acquire at least 90 percent of the fair market value of
     the net assets and at least 70 percent of the fair market value of the
     gross assets held by TB&T Bancshares immediately prior to the transaction.
     For purposes of this representation, amounts paid by TB&T Bancshares or TRD
     to dissenters, amounts paid by TB&T Bancshares to shareholders who receive
     cash or other property, assets of TB&T Bancshares used to pay its
     reorganization expenses, and all redemptions and distributions (except for
     regular, normal dividends) made by TB&T Bancshares immediately preceding
     the transaction will be included as assets of TB&T Bancshares immediately
     prior to the transaction.

          (d)  Prior to the transaction, Texas Regional will be in control of
     TRD within the meaning of 368(c).1

          (e)  Following the transaction, TRD will not issue additional shares
     of its stock that would result in Texas Regional losing control of TRD
     within the meaning of 368(c).

          (f)  The merger of TB&T Bancshares into TRD will qualify as a
     statutory merger under the applicable laws of the states of Delaware and
     Texas, and the merger of Texas Bank & Trust into Texas State Bank will
     qualify as a statutory merger under the applicable laws of the state of
     Texas.

          (g)  Texas Regional, TRD and Texas State Bank have no plan or
     intention to sell or otherwise dispose of any of the assets to be received
     from TB&T Bancshares and Texas Bank & Trust, except for dispositions made
     in the ordinary course of business.

          (h)  Following the proposed transaction, Texas Regional, TRD and Texas
     State Bank will continue to conduct the banking businesses of Texas Bank &
     Trust in a substantially unchanged manner.

          (i)  The liabilities of TB&T Bancshares and Texas Bank & Trust to be
     assumed by TRD and Texas State Bank, respectively, and the liabilities to
     which the transferred assets of TB&T Bancshares and Texas Bank & Trust are
     subject were incurred by TB&T Bancshares and Texas Bank & Trust in the
     ordinary course of their businesses, in each instance.

          (j)  There is no intercorporate indebtedness existing between (i) any
     of TB&T Bancshares or Texas Bank & Trust and (ii) any of Texas Regional,
     TRD or Texas State Bank that was issued, acquired, settled or will be
     settled at a discount.

          (k)  Texas Regional, TB&T Bancshares, TRD, Texas Bank & Trust, Texas
     State Bank and their respective shareholders will pay their own expenses,
     if any, incurred in or arising out of the proposed transaction.

          (l)  None of the parties to the proposed transaction are "investment
     companies" as defined in Section 368(a)(2)(F)(iii) and (iv).

          (m)  The fair market value and the adjusted basis of the assets of
     TB&T Bancshares to be transferred to TRD will each exceed the sum of
     liabilities to be assumed by TRD plus the amount of liabilities to which
     the assets to be transferred are subject.

          (n)  The fair market value and adjusted basis of the assets of Texas
     Bank & Trust to be transferred to Texas State Bank will each exceed the sum
     of liabilities to be assumed by Texas State Bank plus the amount of
     liabilities to which the assets to be transferred are subject.

          (o)  The payment of cash in lieu of fractional shares of Texas
     Regional Common Stock is solely for the purpose of avoiding the expense and
     inconvenience to Texas Regional of issuing fractional shares and does not
     represent separately bargained for consideration. The total cash
     consideration that will be paid in the transaction to the TB&T Bancshares
     shareholders instead of issuing fractional shares of Texas Regional Common
     Stock will not exceed one percent of the total consideration that will be
     given in the transaction to the TB&T Bancshares shareholders in exchange
     for their shares of TB&T Bancshares common stock and no one shareholder
     will receive, in the aggregate, cash in lieu of more than a fractional
     share of Texas Regional Common Stock.

          (p)  Texas Regional has no plan or intention to redeem or otherwise
     reacquire its stock to be issued in the proposed transaction.

          (q)  Texas Regional has no plan or intention to liquidate TRD; to
     merge TRD with and into another corporation; to sell or otherwise dispose
     of the stock of TRD; or to cause TRD to sell or otherwise dispose of any of
     the assets of TB&T Bancshares acquired in the transaction, except for
     dispositions made in the ordinary course of business or transfers described
     in 368(a)(2)(C).

          (r)  Texas Regional and TRD have no plan or intention to sell or
     otherwise dispose of the stock of Texas State Bank or to liquidate Texas
     State Bank.

          (s)  No stock of TRD will be issued in the proposed transaction.

          (t)  Compensation to be paid to shareholder-employees of TB&T
     Bancshares or Texas Bank & Trust after the proposed transaction will be for
     services actually rendered and will be commensurate with amounts paid to
     third parties bargaining at arm's length for similar services. No part of
     such compensation will be in consideration for their TB&T Bancshares stock.

          (u)  The Texas Regional Common Stock to be placed in escrow by Texas
     Regional will be legally issued and outstanding pursuant to state law and
     will appear as issued and outstanding on the balance sheet of Texas
     Regional.

          (v)  All dividends paid on the escrowed stock will be escrowed in
     accordance with the Escrow Agreement.

          (w)  All voting rights of the escrowed stock will be exercisable by
     the TB&T Bancshares shareholders or on behalf of the TB&T Bancshares
     shareholders by their authorized agents.

          (x)  No shares of escrowed stock are subject to restrictions requiring
     their return to Texas Regional because of death, failure to continue
     employment or similar restrictions.

          (y)  All of the escrowed stock will be released from escrow within two
     years of the date of consummation of the transaction unless there are
     unresolved claims specified in the Escrow Agreement. If on the second
     anniversary of the date of execution of the Escrow Agreement there is an
     unresolved claim, the amount of stock held in escrow shall be an amount
     reasonably determined to approximate the amount of losses and damages
     reasonably anticipated to arise out of any claims pending or threatened as
     of the second anniversary.

          (z)  At least 50 percent of the total number of shares of the Texas
     Regional Common Stock issued initially to the shareholders of TB&T
     Bancshares will not be subject to the escrow agreement.

          (aa)  The return of any escrowed shares will not be triggered by an
     event the occurrence or nonoccurrence of which is within the control of the
     shareholders.

          (bb)  The return of any escrowed shares will not be triggered by the
     payment of additional tax or reduction in tax paid as a result of an IRS
     audit of TB&T Bancshares or its shareholders either (i) with respect to the
     reorganization transaction in which such stock will be issued or (ii) when
     the

                                      C-4
<PAGE>
     reorganization transaction in which the escrowed stock will be issued
     involves persons related within the meaning of 267(c)(4).

          (cc)  The mechanism for the calculation of the number of shares of
     escrowed stock to be returned, if any, is objective and reasonably
     ascertainable.

          (dd)  The reason for the escrow arrangement is to provide for a
     purchase price adjustment in the event that Texas Regional or any
     subsidiary of Texas Regional (including Texas State Bank) is required to
     pay any amount of losses or damages arising from certain claims against
     TB&T Bancshares or Texas Bank & Trust.

                                     ISSUE

     Whether (i) the proposed merger of TB&T Bancshares with and into TRD and
(ii) the proposed merger of Texas Bank & Trust with and into Texas State Bank
will each qualify as a reorganization within the meaning of 368(a)(1) and, if
so, what are the federal income tax consequences to Texas Regional, TRD, Texas
State Bank, Texas Bank & Trust, TB&T Bancshares and its shareholders.

                                    OPINION

     Based on the facts and representations set forth above and the Agreement,
it is our view that the federal income tax consequences of the proposed mergers
are as follows:

          (1)  Provided that the merger of TB&T Bancshares with and into TRD
     qualifies as a statutory merger under the applicable laws of the states of
     Delaware and Texas, such merger involving the acquisition by TRD of
     substantially all of the assets of TB&T Bancshares in exchange for Texas
     Regional Common Stock and the assumption by TRD of the liabilities of TB&T
     Bancshares will constitute a reorganization within the meaning of
     368(a)(1)(A) and 368(a)(2)(D). For this purpose, "substantially all"
     means at least ninety percent of the fair market value of the net assets
     and at least seventy percent of the fair market value of the gross assets
     of TB&T Bancshares. Texas Regional, TB&T Bancshares, and Texas Bank & Trust
     will each be a "party to a reorganization" within the meaning of 368(b).

          (2)  Provided that the merger of Texas Bank & Trust with and into
     Texas State Bank qualifies as a statutory merger under the applicable laws
     of the state of Texas, such merger will constitute a reorganization within
     the meaning of 368(a)(1) and Texas Bank & Trust and Texas State Bank will
     each be a "party to a reorganization" within the meaning of 368(b).

          (3)  No gain or loss will be recognized by the shareholders of TB&T
     Bancshares upon receipt of solely Texas Regional Common Stock in exchange
     for TB&T Bancshares common stock (including any fractional share interests
     to which they may be entitled) as described above or upon distribution of
     shares of Texas Regional Common Stock from the escrow pursuant to the
     Escrow Agreement (Section 354(a)(1)).

          (4)  The basis of the Texas Regional Common Stock to be received by
     the shareholders of TB&T Bancshares (including any fractional share
     interests to which they may be entitled and including the shares subject to
     the Escrow Agreement) will be the same as the basis of the TB&T Bancshares
     common stock surrendered in exchange therefor (Section 358(a)(1)).

          (5)  The holding period of the Texas Regional Common Stock to be
     received by the shareholders of TB&T Bancshares (including any fractional
     share interests to which they may be entitled) will include the period
     during which the TB&T Bancshares common stock surrendered in exchange
     therefor was held, provided that the TB&T Bancshares common stock was held
     as a capital asset on the date of the exchange (Section 1223(1)).

          (6)  The payment of cash to TB&T Bancshares shareholders in lieu of
     fractional shares of Texas Regional Common Stock will be treated for
     federal income tax purposes as if the fractional shares were distributed as
     part of the exchange and then were redeemed by Texas Regional. The cash

                                      C-5
<PAGE>
     payments will be treated as having been received as distributions in full
     payment in exchange for the stock redeemed as provided in 302(a) (Rev. Rul.
     66-365, 1966-2 C.B. 116, and Rev. Proc. 77-41, 1977-2 C.B. 574). As
     provided in 1001, gain or loss will be realized and recognized to such
     shareholders measured by the difference between the redemption price and
     the adjusted basis of the Texas Regional Common Stock surrendered as
     determined under 1012.

          (7)  Where cash is received by a dissenting TB&T Bancshares
     shareholder in exchange for his, her or its TB&T Bancshares common stock,
     as described above, such cash will be treated as having been received by
     such shareholder as a distribution in redemption of his, her or its TB&T
     Bancshares common stock subject to the provisions and limitations of 302.

          (8)  No gain or loss will be recognized by TB&T Bancshares upon the
     transfer of substantially all of its assets to TRD in exchange for Texas
     Regional Common Stock and the assumption by TRD of all the liabilities of
     TB&T Bancshares (Sections 361 and 357(a)).

          (9)  No gain or loss will be recognized by Texas Bank & Trust upon the
     transfer of its assets to Texas State Bank in constructive exchange for
     Texas State Bank common stock and the assumption by Texas State Bank of all
     the liabilities of Texas Bank & Trust (Sections 361 and 357(a)).

          (10)  No gain or loss will be recognized by either Texas Regional or
     TRD upon the acquisition by TRD of substantially all of the assets of TB&T
     Bancshares in exchange for Texas Regional Common Stock and the assumption
     by TRD of the liabilities of TB&T Bancshares (Treas. Reg. section 1.1032-2
     and Rev. Rul. 57-278, 1957-1 C.B. 124).

          (11)  No gain or loss will be recognized by Texas State Bank on the
     receipt by Texas State Bank of the assets of Texas Bank & Trust in
     constructive exchange for shares of Texas State Bank stock (Section
     1032(a)).

          (12)  The basis of the assets of TB&T Bancshares and Texas Bank &
     Trust acquired by TRD and Texas State Bank, respectively, will be the same
     as the basis of such assets in the hands of TB&T Bancshares and Texas Bank
     & Trust immediately prior to the exchange (Section 362(b)).

          (13)  Texas Regional Common Stock dividends paid into the escrow
     created pursuant to the Escrow Agreement will be taxed to the TB&T
     Bancshares shareholders upon payment of the dividends to the escrow. TB&T
     Bancshares shareholders will be entitled to a deduction in the event the
     dividends, or a portion thereof are returned to Texas Regional (or TRD),
     pursuant to the Escrow Agreement.

                                     CAVEAT

     No opinions are provided with respect to issues not specifically set forth
in the "OPINION" section of this letter. No inference should be drawn
regarding any matter not specifically opined upon. Our opinion has not been
requested and none is expressed with respect to any foreign, state or local tax
consequences to TB&T Bancshares or its shareholders, Texas Regional or its
shareholders, Texas Bank & Trust, TRD or Texas State Bank including, but not
limited to, income, franchise, sales, use, excise or transfer taxes which may be
significant.

     Our conclusions with respect to the subject transaction are based upon the
assumption that the stock consideration received by the shareholders of TB&T
Bancshares in exchange for their TB&T Bancshares stock consists solely of Texas
Regional Class A Voting Common Stock (other than payments for fractional shares
and payments to dissenters), and no views are expressed with respect to the
subject transaction if consideration other than Texas Regional Common Stock is
issued to the shareholders of TB&T Bancshares in exchange for their shares.

     This opinion letter sets forth our views based on the completeness and
accuracy of the above stated facts and any assumptions that were included. If
any of the foregoing is not entirely complete or accurate, it is imperative that
we be informed immediately, as the inaccuracy or incompleteness could have a
material effect on our conclusions. In rendering our opinion, we are relying
upon the relevant provisions of the

                                      C-6
<PAGE>
Internal Revenue Code of 1986, as amended, the regulations thereunder, and
judicial and administrative interpretations thereof, which are subject to change
or modification by subsequent legislative, regulatory, administrative, or
judicial decisions. Any such changes could also have an effect on the validity
of our opinion. This opinion is not binding on the Internal Revenue Service, any
other tax authority, or any court. No assurance can be given that a position
different than that expressed herein will not be asserted by a tax authority and
sustained by a court.

                                          Very truly yours,

                          INDEPENDENT AUDITORS' REPORT

Board of Directors
TB & T Bancshares, Inc. and Subsidiary

     We have audited the accompanying consolidated balance sheet of TB & T
Bancshares, Inc. (a Texas corporation) and its subsidiary, Texas Bank and Trust,
as of December 31, 1996, and the related statements of income, changes in
shareholders' equity, and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of TB & T
Bancshares, Inc. and its subsidiary at December 31, 1996 and the consolidated
results of their operations and their consolidated cash flows for the year then
ended in conformity with generally accepted accounting principles.

     As discussed in Notes H and K to the financial statements, the Company is
the defendant in a lawsuit and has received threats of potential litigation
arising from allegations of misappropriation of funds by one of the Company's
former employees. Preliminary hearings and discovery proceedings are in
progress. The ultimate outcome of this litigation cannot presently be
determined, but management is of the opinion that it will not have a material
impact on the Company's financial position. Accordingly, no provision for any
liability that may result has been made in the financial statements.

accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

     A summary of the more significant accounting policies follows:

FINANCIAL STATEMENT PRESENTATION

     The consolidated financial statements include the accounts of TB & T
Bancshares, Inc. and its wholly owned subsidiary, Texas Bank & Trust (the
"Bank"). All significant intercompany accounts and transactions have been
eliminated in consolidation. Investments in the subsidiary are accounted for on
the equity method in the Parent's financial statements.

INVESTMENT SECURITIES

     At acquisition, a bank is required to classify debt and equity securities
into one of three categories: held to maturity, trading or available for sale.
At each reporting date, the appropriateness of the classification is reassessed.
Investments in debt securities are classified as held to maturity and measured
at amortized cost in the statement of financial position only if management has
the positive intent and ability to hold those securities to maturity. Securities
that are bought and held principally for the purpose of selling them in the near
term are classified as trading and measured at fair value in the statement of
financial position with unrealized holding gains and losses included in net
income. Investments not classified as held to maturity nor trading are
classified as available for sale and measured at fair value in the statement of
financial position with unrealized holding gains and losses reported in a
separate component of shareholders' equity until realized. At December 31, 1996
and 1995, no securities were classified as trading. The Company has only limited
involvement with derivative financial instruments and does not use them for
trading purposes.

     Gains and losses on the sale of trading and available for sale securities
are determined using the specific-identification method.

     Premiums and discounts are recognized in interest income using the interest
method over the period from acquisition to the earlier of maturity or call date.

                        DECEMBER 31, 1996, 1995 AND 1994

LOANS

     Loans are stated at the principal amount outstanding, net of unearned
discount. Interest income on discounted loans is recognized on the
sum-of-months-digits method which approximates the interest method, while
interest income on other loans is calculated using applicable interest rates and
the daily amount of outstanding principal.

NONPERFORMING ASSETS

     Nonperforming assets are comprised of (a) loans for which the accrual of
interest has been discontinued, (b) loans for which the interest rate has been
reduced to less than originally contracted rates due to a serious weakening in
the borrower's financial condition and (c) other assets which consist of real
estate and other property which have been acquired in lieu of loan balances due
and which are awaiting disposition.

     A loan is generally placed on nonaccrual status when principal or interest
is past due 90 days or more, and the loan is not both well-secured and in the
process of collection. A loan is also placed on nonaccrual status immediately
if, in the opinion of management, full collection of principal or interest is
unlikely. At the time a loan is placed on nonaccrual status, interest previously
recognized but uncollected is reversed and charged against current income.
Subsequent interest payments received on nonaccrual loans are either applied
against principal or reported as income, depending upon management's assessment
of the ultimate collectibility of principal.

     Real estate and other assets acquired in lieu of loan balances due are
recorded at the lesser of cost basis or estimated fair value less estimated
closing costs. Valuation losses are charged to the allowance for loan losses on
foreclosure. Write-downs of real estate and other assets are charged to
noninterest expense if the estimated fair value subsequently declines below its
carrying value. Realized gains and losses on sales of other real estate are
included in noninterest expense.

     Effective January 1, 1995, the Company adopted Statement of Financial
Accounting Standards No. 114, ("Statement 114"), "Accounting by Creditors for
Impairment of a Loan" and the amendment thereof, Statement of Financial
Accounting Standards No. 118, ("Statement 118") "Accounting by Creditors for
Impairment of a Loan-Income Recognition and Disclosures." Under Statement 114,
a loan is considered impaired when, based upon current information and events,
it is probable that a creditor will be unable to collect all amounts due
according to the contractual terms of the loan agreement. Statement 114 requires
that an impaired loan be valued utilizing (i) the present value of expected
future cash flows discounted at the effective interest rate of the loan, (ii)
the fair value of the underlying collateral, or (iii) the observable market
price of the loan. Statement 118 amended Statement 114 by expanding the related
disclosure requirements and permitting use of existing methods for recognizing
interest income on impaired loans.

     Loans which were restructured prior to the adoption of Statement 114 and
which are performing in accordance with the renegotiated terms are not required
to be reported as impaired. Loans restructured subsequent to the adoption of
Statement 114 are required to be reported as impaired in the year of
restructuring. Thereafter, such loans can be removed from the impaired loan
disclosure if the loans were paying a market rate of interest at the time of
restructuring and are performing in accordance with their renegotiated terms.

     For loans covered by this statement, the Company makes an assessment for
impairment when and while such loans are on nonaccrual or when the loan has been
restructured. When a loan with unique risk characteristics has been identified
as being impaired, the amount of impairment will be measured by the Bank using
discounted cash flows, except when it is determined that the sole (remaining)
source of repayment for the loan is the operation or liquidation of the
underlying collateral. In such case, the current

                                      D-8

                        DECEMBER 31, 1996, 1995 AND 1994
fair value of the collateral, reduced by costs to sell, will be used in place of
discounted cash flows. At the time a loan is placed on nonaccrual status,
interest previously recognized but uncollected is reversed and charged against
current income. Subsequent interest payments received on nonaccrual loans are
either applied against principal or reported as income, depending upon
management's assessment of the ultimate collectibility of principal.

     The adoption of Statement 114 and Statement 118 did not have a material
effect on the Company's financial position or results of operations.

ALLOWANCE FOR LOAN LOSSES

     The allowance for loan losses is established by a charge to operations
(provision for loan losses). Actual loan losses or recoveries are charged or
credited directly to this allowance. Management analyzes the loan portfolio to
determine the adequacy of the allowance for loan losses and the appropriate
provision required to maintain an adequate allowance. In assessing the adequacy
of the allowance, management reviews the size, quality and risks of loans in the
portfolio and considers factors such as specific known risks, past experiences,
the status and amount of nonperforming assets and economic conditions. A
specific percentage is allocated to total loans in good standing and additional
amounts are added for individual loans considered to have specific loss
potential. Loans identified as losses are charged-off. In addition, the loan and
discount committee of the Bank reviews the assessment of management in
determining the adequacy of the Bank's allowance for loan losses. Based on total
allocations, the provision is recorded to maintain the allowance at a level
deemed appropriate by management. While management uses available information to
recognize losses on loans, there can be no assurance that future additions to
the allowance will not be necessary.

PREMISES AND EQUIPMENT

     Premises and equipment are stated at cost, net of accumulated depreciation.
Depreciable assets are depreciated over their estimated useful lives. For
financial reporting, depreciation is computed using the straight-line method; in
computing federal income tax, both the straight-line and accelerated methods are
used. Maintenance and repairs which do not extend the life of premises and
equipment are charged to noninterest expense.

INCOME TAX

     Deferred tax assets and liabilities are reflected at currently enacted
income tax rates applicable to the period in which the deferred tax assets or
liabilities are expected to be realized or settled. As changes in tax laws or
rates are enacted, deferred tax assets and liabilities are adjusted through the
provision for income taxes. The Company files a consolidated federal income tax
return.

EARNINGS PER COMMON SHARE COMPUTATIONS

     Primary earnings per common share are computed by dividing net income by
the weighted average number of common stock and common stock equivalents
outstanding during the year. During 1994 and 1995, outstanding debentures are
treated as common stock equivalents

     Fully diluted earnings per share is substantially the same as primary
earnings per share for the Company.

CASH FLOWS

     For purposes of reporting cash flows, cash and cash equivalents include
cash on hand, amounts due from banks and federal funds sold. Generally, federal
funds are purchased and sold for one-day periods.

IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF

     The Company adopted the provisions of Statement of Financial Accounting
Standards No. 121, ("Statement 121") "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of", on January 1,
1996. Statement 121 requires that long-lived assets and certain identifiable
intangibles be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell. Adoption of this Statement did not have a material impact on the Company's
financial position, results of operations or liquidity.

TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES

     In June 1996, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No, 125, ("Statement 125") "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities." Statement 125 is effective for transfers and servicing of
financial assets and extinguishment of liabilities occurring after December 31,
1996 and is to be applied prospectively. Statement 125 provides accounting and
reporting standards for transfers and servicing of financial assets and
extinguishment of liabilities based on consistent application of a
financial-components approach that focuses on control. It distinguishes
transfers of financial assets that are sales from transfers that are secured
borrowings. Management of the Company does not expect that adoption of Statement
125 will have a material impact on the Company's financial position, results of
operations, or liquidity.

NOTE B -- RESERVE REQUIREMENTS

     Cash of approximately $50 thousand at December 31, 1996 and 1995, was
maintained to satisfy regulatory reserve requirements.

     In the ordinary course of business, the Company's subsidiary bank makes
loans to its officers and directors, including entities related to those
individuals. These loans are made on substantially the same terms and conditions
as those prevailing at the time for comparable transactions with other persons
and do not involve more than the normal risk of collectibility or present other
unfavorable features. The balance of loans made to officers and directors,
including loans made to entities related to those individuals, amounted to $934
thousand and $715 thousand at December 31, 1996 and 1995, respectively.

     A summary of the transactions in the allowance for loan losses for years
ended December 31, 1996, 1995 and 1994 follows:

     Nonaccrual loans were $348 thousand, $320 thousand and $474 thousand at
December 31, 1996, 1995 and 1994, respectively. If interest on these nonaccrual
loans had been accrued at the original contractual rates, interest income would
have been increased by approximately $33 thousand, $30 thousand and $45 thousand
for the years ended December 31, 1996, 1995 and 1994, respectively.

     For the years ended December 31, 1996 and December 31, 1995, the deferred
tax liability results primarily from the use of accelerated methods of
depreciation of equipment for tax purposes, from differences in the bad debts
written-off for financial statement purposes and the amount allowed under tax
law, and accrued interest income recognized for book purposes but not for tax
purposes for both years ended December 31, 1996 and 1995, respectively. The
deferred tax asset for both years results primarily from accrued expenses
deducted for book purposes but not for tax purposes.

     A valuation allowance was not considered necessary by the Bank at December
31, 1996 or 1995.

NOTE H -- COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Company enters into various
transactions which, in accordance with generally accepted accounting principles,
are not included on the consolidated balance sheets. These transactions are
referred to as "off-balance sheet commitments." The Company enters into these
transactions to meet the financing needs of its customers. These transactions
include commitments to extend credit and letters of credit which involve
elements of credit risk in excess of the amounts recognized in the consolidated
balance sheets. The Company attempts to minimize its exposure to loss under
these commitments by subjecting them to the same credit approval and monitoring
procedures as its other credit facilities.

     The Company enters into contractual commitments to extend credit, normally
with fixed expiration dates or termination clauses, at specified rates and for
specific purposes. Customers use credit commitments to ensure that funds will be
available for working capital purposes, for capital expenditures and to ensure
access to funds at specified terms and conditions. Substantially, all of the
Company's commitments to extend credit are contingent on customers maintaining
specific credit standards at the time of loan funding. Management assesses the
credit risk associated with certain commitments to extend credit in determining
the level of the allowance for possible loan losses.

     Letters of credit are written for conditional commitments issued by the
Company to guarantee the performance of a customer to a third party. The
Company's policies generally require that letters of credit arrangements contain
security and debt covenants similar to those contained in loan agreements.

                        DECEMBER 31, 1996, 1995 AND 1994

     At December 31, 1996, the Company had outstanding commitments to extend
credit of approximately $818 thousand which included standby letters of credit
of approximately $36 thousand. Management does not anticipate any losses as a
result of these commitments.

     The Company has been named as a defendant in various legal proceedings and
has received threats of potential litigation arising from allegations of
misappropriation of funds by one of the Company's former employees. The
Company's attorneys have just begun the discovery process related to these
proceedings and the amount of loss, if any, that the Company could sustain is
not presently determinable. In addition to the known and threatened litigation,
the Company has paid claims on various losses subsequent to year end, the
majority of which have been reimbursed by the Company's insurance carrier. It is
not possible at this time to estimate the amount of additional claims, if any,
that may arise as a result of the alleged misappropriations. As a result of
these uncertainties, no adjustment has been made to the accompanying financial
statements at December 31, 1996.

NOTE I -- OTHER NONINTEREST EXPENSE

     Other noninterest expense for the years ended December 31, 1996, 1995 and

NOTE J -- REGULATORY MATTERS

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

     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of Total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as

defined). Management believes that the Bank meets all capital adequacy
requirements to which it is subject at December 31, 1996.

     At December 31, 1996, the most recent notification from the Federal Deposit
Insurance Corporation categorized the Bank as adequately capitalized under the
regulatory framework for prompt corrective action. To be categorized as
adequately capitalized, the Bank must maintain minimum total risk-based, Tier I
risk-based, and Tier I leverage ratios as set forth in the table. There are no
conditions or events since that notification that management believes have
changed the institution's category. The Bank's actual capital amounts and ratios
are also presented in the table.

NOTE K -- SUBSEQUENT EVENTS

     In October 1997, the Company entered into an agreement and plan of
reorganization with Texas Regional Bancshares, Inc. whereby the shareholders of
the Company will exchange their stock, subject to the terms of the merger
agreement and related holdback agreement, for stock in Texas Regional
Bancshares, Inc. Upon consummation of the transaction, the Company will be
merged in an anticipated pooling of interest. Completion of the transaction is
also subject to shareholder and regulatory approval.

     The terms of the holdback escrow agreement provide for the deposit of $1.5
million worth of shares of Texas Regional Bancshares, Inc. into escrow pending
the resolution of certain uncertainties discussed in note H. Losses sustained as
a result of these uncertainties will be charged back against the escrow fund in
accordance with the holdback escrow agreement. As a result, the total amount of
Texas Regional Bancshares, Inc. stock and related dividends to be ultimately
distributed to the shareholders of T B & T Bancshares, Inc. may be reduced.

                     TB & T BANCSHARES, INC. AND SUBSIDIARY
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                          SEPTEMBER 30, 1997 AND 1996

NOTE A -- BASIS OF PRESENTATION

     The accompanying compiled consolidated financial statements do not include
all information and footnotes necessary for a fair presentation of financial
position, results of operations and cash flows in conformity with generally
accepted accounting principles. However, the compiled consolidated financial
statements furnished reflect all adjustments which are, in the opinion of
management, necessary for a fair presentation of the results for the interim
periods. All such adjustments were of a normal and recurring nature. The
consolidated financial statements include TB & T Bancshares, Inc. and Subsidiary
(the "Company"). Intercompany balances and transactions have been eliminated.

NOTE B -- INCOME TAX

     Deferred income tax assets and liabilities are computed for differences
between the financial statements and the tax basis of assets and liabilities
that have future tax consequences using the currently enacted tax laws and rates
that apply to the periods in which they are expected to affect taxable income.
Valuation allowances are established, if necessary, to reduce the deferred tax
assets to the amount that will more likely than not be realized. Income tax
expense is the current tax payable or refundable for the period plus or minus
the net change in the deferred tax assets and liabilities.

NOTE C -- COMMITMENTS AND CONTINGENCIES

     The Company has been named as a defendant in various legal proceedings and
has received threats of potential litigation arising from allegations of
misappropriation of funds by one of the Company's former employees. The
Company's attorneys have just begun the discovery process related to these
proceedings and the amount of loss, if any, that the Company could sustain is
not presently determinable. In addition to the known and threatened litigation,
the Company has paid claims on various losses during the nine month period ended
September 30, 1997, the majority of which have been reimbursed by the Company's
insurance carrier. It is not possible at this time to estimate the amount of
additional claims, if any, that may arise as a result of the alleged
misappropriations. As a result of these uncertainties, no adjustment has been
made to the accompanying financial statements at September 30, 1997.

NOTE D -- SUBSEQUENT EVENTS

     In October 1997, the Company entered into an agreement and plan of
reorganization with Texas Regional Bancshares, Inc. whereby the shareholders of
the Company will exchange their stock, subject to the terms of the merger
agreement and related holdback agreement, for stock in Texas Regional
Bancshares, Inc. Upon consummation of the transaction, the Company will be
merged in an anticipated pooling of interest. Completion of the transaction is
also subject to shareholder and regulatory approval.

     The terms of the holdback escrow agreement provide for the deposit of $1.5
million worth of shares of Texas Regional Bancshares, Inc. into escrow pending
the resolution of certain uncertainties discussed in note C. Losses sustained as
a result of these uncertainties will be charged back against the escrow fund in
accordance with the holdback escrow agreement. As a result, the total amount of
Texas Regional Bancshares, Inc. stock and related dividends to be ultimately
distributed to the shareholders of TB & T Bancshares, Inc. and Subsidiary may be
reduced.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article 2.02A(16) and 2.02-1 of the Texas Business Corporation Act grants
to each corporation organized thereunder the power to indemnify its directors
and officers against liability, and to purchase and maintain liability insurance
for those persons as, and to the extent, permitted by Article 2.02-1 of the
Texas Business Corporation Act. In addition, reference is hereby made to Article
V of the Bylaws of the Registrant.

     The general effect of Articles 2.02.A.(16) and 2.02-1 of the Texas Business
Corporation Act, and Article V of the Bylaws of Texas Regional is that the
person may be indemnified only if it is determined that the person conducted
himself in good faith, reasonably believed that the conduct was in the
corporation's best interests (or not opposed to its best interests), and in the
case of criminal proceeding he had no reasonable cause to believe the conduct
was unlawful. In any case, a person may not be indemnified if the basis for
liability was a personal benefit improperly received by the person or if the
person is found liable to the corporation. The indemnification may generally
include judgments, penalties, fines, settlements and reasonable expenses
incurred. Unless the indemnification has been made mandatory in the Articles of
Incorporation or Bylaws of the company, a determination of indemnification must
be made by a majority vote of quorum of directors who at the time are not named
defendants or respondents, or (if such a quorum can not be obtained) by a
committee of the board composed of two or more directors who are not named
defendants or respondents, or by special legal counsel selected in accordance
with prescribed procedures, or by shareholders in a vote that excludes shares
held by directors. Management of Texas Regional is taking the position that the
indemnification under Art. 2.02-1.B has been made mandatory by Article V of
Texas Regional's bylaws. In addition Article 2.02-1 provides that the
corporation shall indemnify a director or officer against reasonable expenses
incurred by him in connection with a proceeding in which he is or was a
defendant or respondent because he is or was a director or officer in which he
has been wholly successful in his defense.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i)  To include any prospectus required by section 10(a)(3) of the
     Securities Act of 1933;

          (ii)  To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective Registration Statement.

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

     (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bonefide offering thereof.

     The undersigned Registrant undertakes to deliver or cause to be delivered
with the prospectus, to each person to whom the prospectus is sent or given, the
latest annual report to security holders that is incorporated by reference in
the prospectus and furnished pursuant to and meeting the requirements of Rule
14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X are not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.

     The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c) the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

                                      II-2
<PAGE>
     The registrant undertakes that every prospectus (i) that is filed pursuant
to the paragraph immediately preceding, or (ii) that purports to meet the
requirements of section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

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

RE:  Issuance of up to 308,076 shares of
     Class A Voting Common Stock of
     Texas Regional Bancshares, Inc.

Gentlemen:

     We have acted as counsel for Texas Regional Bancshares, Inc. (the
"Corporation"), a Texas corporation, in connection with a proposed
registration by the Corporation with the Securities and Exchange Commission on a
Form S-4 Registration Statement (the "Registration Statement") under the
Securities Act of 1933, as amended, of up to 308,076 shares of the Class A
Voting Common Stock of Texas Regional Bancshares, Inc. (the "Stock"), to the
shareholders of TB&T Bancshares, Inc. in exchange for all of the outstanding
capital stock of TB&T Bancshares, Inc. in such merger transaction. Such Stock is
to be issued in connection with the proposed merger of Texas Regional Delaware,
Inc., a corporation wholly owned by the Corporation, with TB&T Bancshares, Inc.

     Before rendering this opinion, we have examined such corporate and other
documents, and such questions of law, as we have considered necessary and
appropriate for the purposes of this opinion, and have relied, as to factual
matters, on certificates and other statements of officers of the Corporation and
others. Based upon the foregoing, we are of the opinion that the shares of Stock
of the Corporation which will be issued in connection with the merger described
in the Registration Statement will, upon consummation of the merger and issuance
and delivery of such shares of Stock to the TB&T Bancshares, Inc., shareholders,
be validly issued, fully paid and nonassessable; provided, however, that any
such shares of Stock as are held in escrow pursuant to the Holdback Escrow
Agreement described in the Registration Statement will be subject to the terms
and provisions of that agreement.

     We hereby consent to the use of our name in the Registration Statement and
the filing of this opinion as an exhibit to the Registration Statement, but we
do not thereby admit that we are within the class of persons whose consent is
required under the terms of the Securities Act of 1933, as amended.

                                          Very truly yours,

                                          McGINNIS, LOCHRIDGE & KILGORE, L.L.P.
