THIS PROSPECTUS. CONTEMPORANEOUSLY WITH THE CLOSING OF THE OFFERING MADE BY THIS

                                  THE COMPANY
 
    Texas  Regional Bancshares,  Inc. ("Texas Regional"  or the  "Company") is a
registered bank holding company whose wholly-owned subsidiary bank, Texas  State
Bank  ("Texas State Bank" or the "Bank"), conducts a commercial banking business
in the  Rio Grande  Valley  of Texas.  At March  31,  1996, Texas  Regional  had
consolidated  assets  of  $655.9  million, loans  outstanding  (net  of unearned
discount) of  $467.1  million,  total  deposits of  $586.0  million,  and  total
shareholders' equity of $64.6 million. For the three months ended March 31, 1996
and  1995,  the Company  earned net  income  of $2.6  million and  $2.0 million,
respectively, for a  return on  average assets for  these periods  of 1.57%  and
1.52%,  respectively. At  March 31, 1996,  the Company  had nonperforming assets
(including loans 90 days or more past  due and still accruing) of $4.9  million,
representing  1.0% of period-end loans and other nonperforming assets (primarily
other real estate). At December 31, 1995, Texas Regional had consolidated assets
of $646.8  million,  loans outstanding  (net  of unearned  discount)  of  $450.9
million,  total deposits  of $579.7 million,  and total  shareholders' equity of
$62.7 million.  For the  years ended  December 31,  1995 and  1994, the  Company
earned  net income of $8.7 million and  $7.2 million, respectively, for a return
on average  assets  for these  periods  of  1.51% and  1.43%,  respectively.  At
December 31, 1995, the Company had nonperforming assets (including loans 90 days
or  more past  due and  still accruing)  of $4.2  million, representing  0.9% of
period-end loans and other nonperforming assets (primarily other real estate).
 
    Texas State Bank operates a total of nine full service banking locations  in
the  Rio Grande  Valley. The  market area  served by  Texas State  Bank has been
recognized  as   among  the   fastest   growing  areas   in  the   nation.   The
McAllen-Edinburg-Mission  area has a  projected population growth  rate of 23.8%
between 1994  and  2000, and  the  Brownsville-Harlingen area  has  a  projected
population  growth rate of 16.0% during  that same period. The business strategy
of Texas Regional is for  the Bank to provide  its customers with the  financial
sophistication  and breadth of products of  a regional bank, while retaining the
local appeal and service level of a community bank. Management believes that the
Company is well positioned in its market due to its responsive customer service,
the strong community involvement of  Texas State Bank management and  employees,
recent trends in the Texas banking environment and the economy of the Rio Grande
Valley.  Management's  strategy  is  to  provide  a  business  culture  in which
individual customers  and small  and medium  sized businesses  are accorded  the
highest priority in all aspects of the Company's operations. Management believes
that  individualized customer  service will  allow the  Company to  increase its
market share in lending volume and deposits. As part of its operating and growth
strategies, the Company is working to attract business from, and provide service
to, small to  medium sized  businesses, and  expand its  operations in  McAllen,
Harlingen and other strategic areas in the Rio Grande Valley.
 
    Consistent  with  this  strategy,  during 1995,  Texas  State  Bank acquired
banking locations in Rio  Grande City and  Roma, Texas, and  in January 1996  it
entered into definitive agreements to acquire two banks headquartered in Mission
and Hidalgo, Texas. See "The Company" and "Proposed Mergers."
 
    At  March  31,  1996,  Texas  Regional  employed  351  full  time equivalent
employees. The address of Texas Regional's principal executive office is  Kerria
Plaza,  Suite  301,  3700  North  10th Street,  McAllen,  Texas  78501,  and its
telephone number is (210) 631-5400.

                                  THE MERGERS
 
    Texas State Bank has for some time sought appropriate acquisitions to permit
the Bank to expand within the market  areas served by Texas State Bank and  into
adjacent  market areas in  the Rio Grande  Valley. In January  1996, the Company
entered into definitive agreements to acquire through merger First State Bank  &
Trust  Co., Mission,  Texas ("First State  Bank") and The  Border Bank, Hidalgo,
Texas ("Border Bank")  (the "Mergers").  First State  Bank and  Border Bank  had
combined  total  assets  of  approximately $545.5  million  at  March  31, 1996.
Assuming consummation of the Mergers,  on a pro forma  basis at March 31,  1996,
Texas  Regional would have had total assets  of $1.172 billion, which would have
made Texas Regional the  largest bank holding company  headquartered in the  Rio
Grande  Valley. At March 31,  1996, First State Bank  had total assets of $426.1
million, loans  outstanding (net  of unearned  discount) of  $192.8 million  and
stockholders'  equity of $61.6 million. At March 31, 1996, Border Bank had total
assets of $119.9 million, loans outstanding (net of unearned discount) of  $51.0
million  and stockholders' equity of $17.2  million. First State Bank and Border
Bank had combined total assets of  approximately $524.0 million at December  31,
1995. Assuming consummation of the Mergers, on a pro forma basis at December 31,
1995,  Texas Regional would have had total assets of $1.144 billion. At December
31, 1995, First State Bank had total assets of $404.5 million, loans outstanding
(net of unearned discount) of $188.4  million and stockholders' equity of  $59.4
million.  At December 31, 1995, Border Bank  had total assets of $119.5 million,
loans outstanding (net of unearned discount) of $47.3 million and  stockholders'
equity  of $17.1 million. Elliot B. Bottom is  the Chairman of the Board of both
First State  Bank  and  Border  Bank, and  the  banks  have  substantial  common
ownership.  The  purpose of  the Mergers  is to  further strengthen  Texas State
Bank's branch network and  banking business in the  Rio Grande Valley by  adding
six  new banking locations in Mission,  Penitas, McAllen and Hidalgo, Texas. The
purchase price for the Mergers is  estimated to be $99.5 million,  approximately
$40.0  million of  which will  be paid  from the  proceeds of  the offering made
hereby.  The  Company  intends  to  fund  the  balance  of  the  purchase  price
principally  from liquidation of cash equivalents  and, to the extent necessary,
selected investment securities on a  consolidated basis. See "Proposed  Mergers"
and "Use of Proceeds."
 
    Management  of Texas  State Bank believes  that the Mergers  will expand the
Company's community  banking  network  into  contiguous  markets,  substantially
increasing  its market share  and enabling the Bank  to compete more effectively
with other  financial institutions  in the  Rio Grande  Valley. Because  of  the
proximity  of Mission to McAllen, there is  a substantial overlap in the markets
served by Texas State Bank and First State Bank. For this reason and because the
banks serve a  similar customer base,  First State Bank  is considered by  Texas
State  Bank management to be a direct competitor of Texas State Bank, particular
as to loan customers. The new or expanded services to be offered to First  State
Bank  and  Border  Bank  customers include  enhanced  data  processing services,
additional automated teller facilities and  other services now offered to  Texas
State  Bank customers.  Texas State  Bank management  believes that  First State
Bank, Border Bank and Texas State Bank customers will benefit from the expansion
of Texas State Bank's  branch network from nine  to 15 banking locations.  Texas
State  Bank expects to realize certain operating and administrative efficiencies
as  a  result  of   the  Mergers;  however,  because   of  the  relatively   low
employee-to-asset ratio at First State Bank and Border Bank, cost savings is not
a  principal motivating factor for the Mergers. The operating efficiencies which
are expected include  the use  by all banking  locations of  the existing  Texas
State  Bank  data processing  facility, operation  of  a single  human resources
department, and economies of a combined advertising program.

                SUMMARY PRO FORMA COMBINED FINANCIAL INFORMATION
 
    The following unaudited summary pro forma combined financial information has
been derived  from  the historical  consolidated  financial information  of  the
Company,  adjusted  to give  effect to  the proposed  acquisition of  assets and
assumption of liabilities in connection with the Mergers, the estimated purchase
accounting adjustments resulting from the Mergers, and the proposed issuance  of
Common  Stock  in the  offering herein  described (assuming  no exercise  of the
Underwriters' over-allotment option), as  though such transactions had  occurred
on  March 31, 1996 and  December 31, 1995, respectively.  The pro forma combined
financial information is not necessarily indicative of the financial position or
results of  operations  that  would  have been  achieved  had  the  transactions
reflected therein occurred on such date or that may occur in the future. The pro
forma  adjustments  with  respect to  the  Mergers  reflect March  31,  1996 and
December 31, 1995 balances and are subject  to change prior to the closing  date
of  the Mergers. The  summary pro forma combined  financial information does not
purport to project the consolidated financial information of the Company for any
future period. The information  should be read in  conjunction with (i) the  pro
forma   financial  information,  including  the  notes  thereto,  which  appears
elsewhere in this  Prospectus, and  (ii) the  historical consolidated  financial
statements  of Texas Regional,  First State Bank and  Border Bank, including the
respective notes  thereto,  which  appear  elsewhere  in  this  Prospectus.  See
"Proposed  Mergers,"  "Texas  Regional  Bancshares,  Inc.  Selected Consolidated
Financial Information" and "Index to Financial Statements."

                                  RISK FACTORS
 
    IN  ADDITION  TO THE  OTHER INFORMATION  IN  THIS PROSPECTUS,  THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE SHARES
OF COMMON STOCK OFFERED BY THIS PROSPECTUS.
 
    RISKS OF THE MERGER -- GENERAL.  Upon completion of the Mergers, Texas State
Bank's size  will be  substantially increased  in terms  of assets  and  deposit
liabilities.  The increases in  assets and deposits  will be in  addition to the
substantial increases in assets and deposits already experienced by Texas  State
Bank over the last two years. In addition, the Company has not historically made
acquisitions  on the same scale as the  Mergers, and the future prospects of the
Company will depend,  in significant  part, on  a number  of factors,  including
Texas  State Bank's ability  to compete effectively in  the Mission and Hidalgo,
Texas market areas; its ability to limit the outflow of deposits in the acquired
banking locations formerly part of First State Bank and Border Bank; its success
in retaining earning assets,  particularly loans, acquired  in the Mergers,  and
its  ability to generate new earning  assets; its ability to control noninterest
expense in order to maintain a  favorable overall efficiency ratio; its  ability
to  attract and retain  qualified management and  other appropriate personnel to
staff the newly acquired banking locations;  and its ability to earn  acceptable
levels  of noninterest  income from the  banking locations. No  assurance can be
given as to any  of the foregoing or  that the Company's existing  profitability
will  not be adversely affected by the  operations of First State Bank or Border
Bank, that the Company will be able to achieve results in the future similar  to
those  achieved  in  the  past, or  that  the  Company will  be  able  to manage
effectively the growth resulting from the Mergers. In addition, the Mergers will
restrict  the  Company's  ability   to  consummate  other  possible   beneficial
transactions  which require further leverage or  would result in the creation of
additional intangibles. See "Proposed Mergers."
 
    RISKS OF THE MERGER -- CREDIT QUALITY.  In connection with the Mergers,  the
Company  or its  representatives reviewed the  First State Bank  and Border Bank
loan portfolios. This  review included  all loans on  the First  State Bank  and
Border Bank watch lists, a substantial proportion of the loans to borrowers with
other  large lines of credit and selected  other loans in each bank's portfolio.
The Company's examinations  were made  using criteria,  analyses and  collateral
evaluations  that the Company  has traditionally used in  the ordinary course of
its business. Nonperforming  assets (including  accruing loans 90  days or  more
past  due) at March 31, 1996 totaled $5.2 million at First State Bank and Border
Bank compared  to  $4.9  million  at  Texas  State  Bank.  Nonperforming  assets
(including accruing loans 90 days or more past due) at December 31, 1995 totaled
$9.6  million at First  State Bank and  Border Bank compared  to $4.2 million at
Texas State Bank. See "First State Bank & Trust Co. Management's Discussion  and
Analysis  of Financial Condition and Results of Operations" and "The Border Bank
Management's Discussion  and  Analysis of  Financial  Condition and  Results  of
Operations."  Management of Texas  Regional believes that  the credit quality of
the loan portfolio of First State Bank and Border Bank is nonetheless acceptable
in terms  of risk  and that  the  increased risk  is expected  to be  offset  by
increased  reserves  and higher  interest  rates on  certain  classifications of
loans. In addition,  as a result  of the  Mergers, the allowance  for loan  loss
reserves  will increase.  At March  31, 1996,  the Company's  allowance for loan
losses was 1.05% of total loans, while on  a pro forma basis at March 31,  1996,
the Company's allowance for loan losses would have been 1.41% of total loans. At
December  31, 1995, the Company's  allowance for loan losses  was 1.01% of total
loans, while on a pro forma basis at December 31, 1995, the Company's  allowance
for  loan losses would have been 1.44% of  total loans. However, there can be no
assurance as to  the future performance  of the loan  portfolio acquired in  the
Mergers.
 
    RISKS  OF THE  MERGER --  COMPLIANCE AND  MANAGEMENT.   On October  8, 1993,
Border Bank entered into a Memorandum of Understanding with the Texas Department
of Banking (the  "Banking Department"), and  on December 14,  1993, First  State
Bank entered into a Memorandum of Understanding with the Banking Department. The
Memorandum of Understanding applicable to each bank requires each bank to, among
other  things, (i) develop and follow policies related to loan documentation and
review, (ii) increase (and continue monitoring the adequacy of) each bank's loan
valuation reserve, and (iii) review each bank's investment and funds  management
policies.  Texas  State  Bank  has  reviewed  deficiency  letters  received from
applicable regulatory authorities related  to each Memorandum of  Understanding,
which,  among other things, indicate that  in the judgment of certain regulatory
authorities First
 
                                       8
<PAGE>
State Bank and  Border Bank had  not yet adequately  addressed the  deficiencies
identified  in the Memoranda of Understanding.  See "Proposed Mergers." Prior to
entering into  the agreements  relating to  the Mergers,  First State  Bank  and
Border   Bank  began  to  implement  additional  corrective  efforts,  including
retaining an outside consultant  to assist in  documentation and policy  reviews
for  First State Bank and Border Bank. Texas State Bank management believes that
the implementation  of  Texas State  Bank's  policies and  procedures,  and  the
application  of Texas State Bank's internal  controls, make it unlikely that the
deficiencies identified  in the  Memoranda of  Understanding will  be  repeated,
although  there can  be no  certainty that  all deficiencies  will be adequately
addressed to  the  satisfaction of  applicable  regulatory authorities.  If  the
problems  addressed  in  the  Memoranda  of  Understanding  persist,  they could
adversely affect the future operations of the Company.
 
    Following consummation of  the Mergers,  (i) all lending  at the  facilities
formerly operated by First State Bank and Border Bank will be conducted pursuant
to  Texas State Bank's policies and under  the supervision of Texas State Bank's
Chief Lending Officer, Frank A. Kavanagh, (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)  following  conversion  (which is
expected by Texas Regional management to occur in fall 1996) 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
locations formerly operated as First State Bank and Border Bank facilities, will
be Texas State Bank's  policies and procedures.  Nonperforming assets and  loans
presently  past due on the  books of First State Bank  and Border Bank have been
reviewed by or  on behalf  of Texas  State Bank and  those loans  which, in  the
judgment of Texas State Bank, represent probable losses will be recorded at zero
at  the time  of consummation  of the  Mergers, although  Texas State  Bank will
nonetheless pursue collection in appropriate circumstances.
 
    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,  First State  Bank and  Border Bank  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  these
competitors  have substantially greater resources  and lending limits than Texas
State Bank has or will have following the Mergers, and many of 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.
 
    RELIANCE ON  CHIEF  EXECUTIVE  OFFICER.    Texas  Regional  has  experienced
substantial  growth in assets and deposits  during the recent past, particularly
since Glen E. Roney became Chairman of the Board and Chief Executive Officer  of
the Company in 1985. Although Mr. Roney is the largest individual 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 the  Company's
business and prospects. See "Management -- Executive Compensation."
 
    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 ("FRB")  and the  Banking
Department.  These laws  and regulations are  designed primarily  to protect the
Bank Insurance  Fund  of the  Federal  Deposit Insurance  Corporation  ("FDIC"),
depositors   and  borrowers,  and  to   further  certain  social  policies  and,
consequently, may  impose limitations  on the  Company that  may not  be in  the
 
                                       9
<PAGE>
best  interests of  the Company  and holders of  Common Stock.  See "Business --
Regulation and Supervision" and "Business -- Capital Resources." The Company and
the Bank are subject to changes in federal and state laws, as well as changes in
rules  and  regulations,  governmental   policies  and  changes  in   accounting
principles.  The effects of any such  potential changes cannot be predicted, but
they could have an adverse effect on the business and operations of the  Company
and the Bank.
 
    DILUTION.   At  March 31, 1996,  the net  tangible book value  of the Common
Stock was $9.52 per  share. "Net tangible book  value per share" represents  the
tangible  net  worth  of  the  Company  (total  assets  less  intangible  assets
(including goodwill) and total liabilities), divided by the number of shares  of
Common  Stock  outstanding.  Without  taking into  account  any  changes  in net
tangible book value after March 31, 1996, after giving effect to the sale by the
Company of 2,180,000 shares of Common  Stock offered hereby and after  deducting
underwriting  discounts, commissions and estimated  offering expenses, and after
giving effect to the Mergers (assumed  to have been consummated effective  March
31,  1996), the pro forma  net tangible book value at  March 31, 1996 would have
been $10.09 per share,  representing an increase of  $0.57 per share to  current
shareholders and a dilution of $12.16 per share to persons purchasing the shares
offered hereby.
 
    CONCENTRATION  OF OWNERSHIP.  After issuance of the 2,180,000 shares offered
by the  Company pursuant  to  this Prospectus,  officers  and directors  of  the
Company,  and affiliates of  those persons, will beneficially  own 17.83% of the
Company's  outstanding  Common  Stock  (or  17.17%  assuming  the  Underwriters'
overallotment  option is  exercised in full).  See "Principal  Holders of Common
Stock." Accordingly, such persons have the ability to act together as a group to
direct the Company's affairs and business, which may include taking actions that
may not be in the interests of the other shareholders.
 
    SHARES AVAILABLE FOR FUTURE SALE.   The future sale of a substantial  number
of  shares of Common  Stock by existing  shareholders, or the  sale of shares of
Common Stock by shareholders purchasing shares of Common Stock in this offering,
could have a material adverse  effect on the market  price of the Common  Stock.
The  Company, its directors and executive  officers, and the Selling Shareholder
have agreed that for  a period of  120 days after the  date of this  Prospectus,
they  will not, directly or indirectly, sell  or otherwise dispose of any shares
of Common Stock (except for shares of Common Stock offered hereby and other than
shares offered pursuant to  the Texas Regional  Bancshares, Inc. Employee  Stock
Ownership  Plan (with 401(k) provisions) (the  "KSOP") or other employee benefit
plans) without the prior written consent of the Underwriters. See "Underwriting"
and "Shares Eligible for Future Sale."
 
    LIMITED MARKET FOR COMMON STOCK.  The Common Stock is held by  approximately
636  shareholders of record. The  total trading volume for  the Common Stock for
the three months ended March  31, 1996, as reported  on the Summary of  Activity
for  March 1996, prepared by The Nasdaq  Stock Market for the Company, indicates
that total share volume was 396,700  shares during the three months ended  March
31,  1996, representing an aggregate of 57  trades. The total trading volume for
the Common Stock for 1995, as reported  on the Summary of Activity for  December
1995,  prepared by The Nasdaq Stock Market for the Company, indicates that total
share volume was 752,910  shares during 1995, representing  an aggregate of  337
trades.  Alex. Brown & Sons Incorporated and First Southwest Company have made a
market in the Common  Stock since March  1994 (when the  Common Stock was  first
qualified  for trading through the Nasdaq  National Market System), and each has
advised the Company that  they intend to  make a market in  the Common Stock  as
long  as the volume  of trading activity  in the Common  Stock and certain other
market-making  considerations  justify  doing  so.  However,  there  can  be  no
assurance  that a liquid trading market for  the Common Stock will develop, that
it will  continue if  it does  develop, or  that after  the completion  of  this
offering the Common Stock will trade at or above the offering price set forth on
the cover of this Prospectus. Making a market involves maintaining bid and asked
quotations  for the Common  Stock and being  available as a  principal to effect
transactions in reasonable quantities at those quoted prices, subject to various
securities laws  and  other regulatory  requirements.  A public  trading  market
having  the desired characteristics of  depth, liquidity and orderliness depends
upon the presence in the marketplace of willing buyers and sellers of the Common
Stock at  any  given time,  which  presence  is dependent  upon  the  individual
decisions  of investors and  general economic and  market conditions, over which
neither the Company nor any market-maker has control.

                                USE OF PROCEEDS
 
    The net  proceeds to  Texas  Regional from  this offering,  after  deducting
estimated  expenses  of the  offering, are  estimated to  be $45.2  million. The
Company intends  to use  $40.0 million  of the  proceeds from  this offering  to
finance  a portion of the consideration to  the shareholders of First State Bank
and Border Bank in the Mergers. The remainder of the net proceeds, if any,  will
be  used for general corporate  purposes. The total consideration  to be paid to
both First State Bank and Border  Bank shareholders in the Mergers is  estimated
to   be  $99.5  million.  The  Company  intends  to  fund  the  balance  of  the
consideration principally  from  liquidation of  cash  equivalents and,  to  the
extent  necessary, selected investment  securities on a  consolidated basis. See
"Texas  Regional  Bancshares,  Inc.  Pro  Forma  Combined  Condensed   Financial
Information."
 
    Consummation  of  the  offering  herein  described  is  subject  to  certain
conditions, including  the  contemporaneous  consummation of  the  Mergers.  See

                                  THE COMPANY
 
    Texas  Regional  is a  registered  bank holding  company  whose wholly-owned
subsidiary bank, Texas State Bank, conducts a commercial banking business in the
Rio Grande Valley of  Texas. At March 31,  1996 Texas Regional had  consolidated
assets of $655.9 million, loans outstanding (net of unearned discount) of $467.1
million,  total deposits  of $586.0 million,  and total  shareholders' equity of
$64.6 million. For the three months ended  March 31, 1996 and 1995, the  Company
earned  net income of $2.6 million and  $2.0 million, respectively, for a return
on average assets for these periods  of 1.57% and 1.52%, respectively. At  March
31,  1996, the Company had nonperforming assets (including loans 90 days or more
past due and still  accruing) of $4.9 million,  representing 1.0% of  period-end
loans  and other nonperforming assets (primarily other real estate). At December
31, 1995,  Texas  Regional had  consolidated  assets of  $646.8  million,  loans
outstanding  (net of  unearned discount)  of $450.9  million, total  deposits of
$579.7 million, and total shareholders' equity  of $62.7 million. For the  years
ended December 31, 1995, and 1994, the Company earned net income of $8.7 million
and $7.2 million, respectively, for a return on average assets for these periods
of  1.51%  and  1.43%,  respectively.  At December  31,  1995,  the  Company had
nonperforming assets (including accruing loans 90 days or more past due) of $4.2
million, representing 0.9%  of period-end loans  and other nonperforming  assets
(primarily other real estate).
 
    Assuming  consummation of  the Mergers,  on a pro  forma basis  at March 31,
1996, Texas Regional would have had consolidated assets of $1.172 billion, loans
outstanding (net  of unearned  discount) of  $709.6 million,  total deposits  of
$1.049  billion,  and total  shareholders'  equity of  $109.8  million. Assuming
consummation of the  Mergers, on  a pro  forma basis  at March  31, 1996,  Texas
Regional  would have had non-performing assets (including accruing loans 90 days
or more past due)  of $10.1 million, representing  1.0% of period-end loans  and
other  nonperforming assets (primarily other real estate). Assuming consummation
of the Mergers, on a pro forma basis at December 31, 1995, Texas Regional  would
have  had  consolidated  assets of  $1.144  billion, loans  outstanding  (net of
unearned discount)  of $685.3  million, total  deposits of  $1.024 billion,  and
total  shareholders'  equity of  $107.9  million. Assuming  consummation  of the
Mergers, on a pro forma basis at  December 31, 1995 Texas State Bank would  have
had non-performing assets (including accruing loans 90 days or more past due) of
$13.8  million, representing  2.0% of  period-end loans  and other nonperforming
assets (primarily other real estate).
 
    All of Texas Regional's operations are located in the Rio Grande Valley, and
therefore the  ability of  Texas Regional  to continue  its rate  of growth  and
profitability is closely linked to the economy of the Rio Grande Valley. The Rio
Grande  Valley is  composed of the  following Texas  counties: Hidalgo, Cameron,
Willacy and  Starr (the  "Rio Grande  Valley"). The  economy of  the Rio  Grande
Valley  is  based  principally  on  retailing  (including  trade  with  Mexico),
government, agriculture, tourism,  manufacturing, health care  and education.  A
large number of retirees spend all or part of the year in the Rio Grande Valley.
Many  twin manufacturing and assembly plants,  or "maquiladoras," are located in
the Rio Grande  Valley or  in communities located  across the  border in  Mexico
(such  as Reynosa and Matamoros). The market area served by Texas State Bank has
been  recognized  as  among  the  fastest  growing  areas  in  the  nation.  The
McAllen-Edinburg-Mission  area has a  projected population growth  rate of 23.8%
between 1994  and  2000, and  the  Brownsville-Harlingen area  has  a  projected
population growth rate of 16.0% during that same period.
 
    Texas  State Bank has a total of  nine full service banking locations in the
Rio Grande Valley  through which  the Bank offers  a broad  range of  commercial
banking  services. The Bank intends  to operate all of  the banking locations of
First State Bank and  Border Bank and, after  consummation of the Mergers,  will
have  15 full service  banking locations. The  Bank serves as  a community bank,
providing for the banking needs of retailers, manufacturers, food producers  and
processors, real estate developers and builders, and other businesses in the Rio
Grande  Valley.  For  commercial  customers, Texas  State  Bank  offers checking
facilities, certificates  of  deposit,  short-term  loans  for  working  capital
purposes,  construction financing,  mortgage loans,  loans for  fixed assets and
expansion  needs  and  other  commercial   loans.  The  services  provided   for
individuals  by Texas  State Bank  include checking  accounts, savings accounts,
certificates of  deposit,  individual  retirement  accounts  and  consumer  loan
programs,  including installment  loans for  home repairs  and for  purchases of
consumer goods, including automobiles, trucks and
 
                                       12
<PAGE>
boats,  mortgage  loans,  travelers  checks,  money  orders  and  safe   deposit
facilities. Where the borrowing needs of a customer exceed the lending limits of
the  Bank, the Bank may participate with other banks in the making of such loan.
The Bank also offers trust services  to commercial and individual customers.  At
March  31, 1996, total  trust assets under  management by Texas  State Bank were
$257.2 million and on a  pro forma basis at March  31, 1996, total trust  assets
under management by Texas State Bank would have been $269.8 million. At December
31,  1995 and 1994, total trust assets under management by Texas State Bank were
$237.4 million  and  $192.4 million,  respectively.  On  a pro  forma  basis  at
December 31, 1995, total trust assets under management by Texas State Bank would
have been $248.9 million.
 
    Due to its close proximity to Mexico, Texas State Bank has developed banking
relations  with  depositors  who  are  Mexican  residents.  At  March  31, 1996,
approximately 10.1% of the  total demand and time  deposits in Texas State  Bank
were  deposited by or  on behalf of  residents of Mexico.  Many of the Company's
Mexican  customers  are  long-term  customers  of  Texas  State  Bank  or   have
long-standing  relationships with  senior management.  On a  pro forma  basis at
March 31,  1996, approximately  14.0%  of the  combined  total demand  and  time
deposits in Texas State Bank, First State Bank and Border Bank were deposited by
or  on behalf  of residents  of Mexico, and  approximately 2.3%  of the combined
total loans of Texas State Bank, First  State Bank and Border Bank were  secured
by  non-U.S.  collateral,  primarily real  estate  and other  assets  located in
Mexico. Management does not believe  that the Bank's profitability is  dependent
on business from Mexican depositors and loan customers.
 
    Texas  State Bank is a  member of the Federal Reserve  System, and acts as a
correspondent to  a  number  of  banks in  its  service  area,  providing  check
clearing,  wire transfer,  federal fund transactions,  loan participations, data
processing and other correspondent services.
 
    Texas State Bank's business  strategy is to provide  its customers with  the
financial  sophistication  and breadth  of products  of  a regional  bank, while
retaining the local appeal and level of service of a community bank.  Management
believes  that the Bank is  well positioned in its  market due to its responsive
customer  service,  the  strong  community  involvement  of  Texas  State   Bank
management  and employees,  recent trends in  the Texas  banking environment and
recent trends in the economy of the Rio Grande Valley. Management's strategy  is
to provide a business culture in which individual customers and small and medium
sized  businesses are accorded the highest priority in all aspects of the Bank's
operations. Management believes that individualized customer service will  allow
the Bank to increase its market share in lending volume and deposits. As part of
its  operating and growth strategies, the Bank intends to attract business from,
and provide  service  to, small  to  medium  sized businesses,  and  expand  its
operations in the Rio Grande Valley.
 
    Consistent  with the Company's  growth strategy, in  August 1995 Texas State
Bank acquired the Rio Grande  City and Roma branches  of First National Bank  of
South  Texas  (the "RGC/Roma  Branch Acquisitions").  In the  acquisition, Texas
State Bank  assumed  deposit liabilities  amounting  to an  aggregate  of  $79.7
million,  and acquired loans (net of  unearned discount) of $43.7 million, fixed
assets (after giving effect to purchase accounting adjustments) of $1.6 million,
and other assets, including foreclosed properties, of $100,000. Texas State Bank
paid a net premium (after purchase  accounting adjustments) of $4.1 million  for
the  business, and the  difference of approximately $30.6  million was funded in
cash by First  National Bank of  South Texas. The  RGC/Roma Branch  Acquisitions
provided Texas State Bank with two banking locations in Starr County, Texas.
 
    Texas State Bank has for some time sought appropriate acquisitions to permit
the  Bank to expand within the market areas  served by Texas State Bank and into
adjacent market  areas. In  January 1996,  the Company  entered into  definitive
agreements  to acquire  through merger First  State Bank and  Border Bank. First
State Bank and  Border Bank had  combined total assets  of approximately  $545.5
million  at March 31, 1996, which, on a pro forma basis at March 31, 1996, would
have resulted in Texas Regional increasing  its total assets to $1.172  billion,
making  Texas Regional the largest bank holding company headquartered in the Rio
Grande Valley. First  State Bank and  Border Bank had  combined total assets  of
approximately  $524.0 million at December 31, 1995,  which, on a pro forma basis
at December 31, 1995, would have resulted in Texas Regional increasing its total
assets to $1.144 billion. The purpose of the
 
                                       13
<PAGE>
Mergers is to further strengthen Texas  State Bank's branch network and  banking
business  in  the Rio  Grande  Valley by  adding  six new  banking  locations in
Mission, Penitas, McAllen and Hidalgo, Texas. The purchase price for the Mergers
is estimated to be $99.5 million,  approximately $40.0 million of which will  be
paid  from the proceeds of the offering made hereby. The Company intends to fund
the balance principally from liquidation of cash equivalents and, to the  extent
necessary, selected investment securities on a consolidated basis. See "Proposed
Mergers" and "Use of Proceeds."
 
    The banking industry in the market area served by Texas State Bank is highly
competitive,  with  competition from  other commercial  banks, savings  and loan
associations, credit unions, mortgage banking companies, commercial and consumer
finance companies, securities broker-dealers,  mutual fund companies,  insurance
agents  and companies and other financial  institutions, located both within and
outside of the Rio Grande Valley.
 
    Texas Regional is subject to regulation by the FRB, and Texas State Bank  is
subject  to regulation  by both the  Banking Department and  its primary federal
regulator, the FRB. Such  regulations are primarily  designed for protection  of
depositors   and  not  for   the  benefit  of   the  shareholders  of  financial
institutions. See "Business -- Regulation and Supervision" and "Risk Factors  --
Regulatory Restrictions and Requirements."
 
    At  March  31,  1996,  Texas  Regional  employed  351  full  time equivalent
employees. On a pro forma basis at March 31, 1996, after giving consideration to
the Mergers, the Company would have employed 494 full time equivalent employees.
Substantially all of the present First  State Bank and Border Bank officers  and
employees  are expected to be employed by Texas State Bank. The address of Texas
Regional's principal executive  office is  Kerria Plaza, Suite  301, 3700  North
10th Street, McAllen, Texas 78501, and its telephone number is (210) 631-5400.
 
                                PROPOSED MERGERS
 
GENERAL
 
    The Company, through its subsidiary Texas State Bank, has agreed to acquire,
through the Mergers, First State Bank and Border Bank. Management of Texas State
Bank  believes  that the  Mergers will  expand  the Company's  community banking
network into contiguous markets, substantially  increasing its market share  and
enabling  the Bank to compete more effectively with other financial institutions
in the Rio Grande Valley.  The new or expanded services  to be offered to  First
State  Bank and Border Bank customers include enhanced data processing services,
additional automated teller facilities and  other services now offered to  Texas
State  Bank customers.  Texas State  Bank management  believes that  First State
Bank, Border Bank and Texas State Bank customers will benefit from the expansion
of Texas State Bank's  branch network from nine  to 15 banking locations.  Texas
State  Bank expects to realize certain operating and administrative efficiencies
as  a  result  of   the  Mergers;  however,  because   of  the  relatively   low
employee-to-asset ratio at First State Bank and Border Bank, cost savings is not
a  principal motivating factor for the Mergers. The operating efficiencies which
are expected include  the use  by all banking  locations of  the existing  Texas
State  Bank  data processing  facility, operation  of  a single  human resources
department, and economies of a combined advertising program.
 
    The terms of the merger of First  State Bank are set forth in the  Agreement
and  Plan of Reorganization dated January 9, 1996, as amended on March 29, 1996,
by and between the Company, Texas State Bank and First State Bank ("First  State
Bank  Agreement"), and the terms  of the merger of Border  Bank are set forth in
the Agreement and Plan  of Reorganization dated January  9, 1996, as amended  on
March  29, 1996, between the Company, Texas  State Bank and Border Bank ("Border
Bank Agreement") (the First State Bank  Agreement and the Border Bank  Agreement
are  collectively called the  "Merger Agreements," copies of  which are filed as
exhibits to the Registration Statement). Subject to the terms and conditions  of
the  Merger Agreements, certain shareholders of First State Bank and Border Bank
have joined into the Merger Agreements to evidence their consent to the  Mergers
and  their  agreement to  vote their  shares in  favor of  the Mergers  at their
respective shareholders meetings.  The Merger  Agreements provide  that, at  the
time of the closing of the Mergers (the "Closing"), the net worth of First State
Bank will not be less
 
                                       14
<PAGE>
than  $62.0 million and the net worth of Border Bank will not be less than $17.3
million. Elliot B. Bottom is the Chairman of the Board of both First State  Bank
and Border Bank, and the banks have substantial common ownership.
 
    First  State  Bank, the  principal office  of which  is located  in Mission,
Texas, was chartered in  1909, and Border Bank,  located in Hidalgo, Texas,  was
chartered  in 1968. Because of  the proximity of Mission  to McAllen, there is a
substantial overlap in the  markets served by Texas  State Bank and First  State
Bank. For this reason and because the banks serve a similar customer base, First
State  Bank  is  considered  by  Texas State  Bank  management  to  be  a direct
competitor of Texas State Bank, particular as to loan customers.
 
    All of  the offices  of First  State Bank  and Border  Bank are  located  in
Hidalgo  County, Texas, and  all such locations  are expected to  continue to be
operated by Texas  State Bank, under  the Texas State  Bank name, following  the
Mergers. Both First State Bank and Border Bank are full service community banks.
The products and services offered at these locations will be expanded to include
all products and services offered by Texas State Bank.
 
    Substantially  all of the current officers and employees of First State Bank
and Border Bank are expected  to be employed by  Texas State Bank following  the
Mergers.  Elliott Bottom,  the President  and Chief  Executive Officer  of First
State Bank,  will  become  President  of  Texas  State  Bank's  Mission  banking
locations,  with  principal  operating responsibility  for  the  Mission banking
locations, and Brent Bottom, the President of Border Bank, will become the Chief
Executive Officer of Texas  State Bank's Hidalgo  banking location. Texas  State
Bank  management believes that this continuity of management will provide for an
orderly transition and will minimize the loss of customer relationships.
 
    The Mergers are  subject to  a number  of conditions,  including receipt  of
approval  from applicable regulatory  authorities. Both the  FRB and the Banking
Department have approved the Mergers,  subject to certain conditions,  including
the  successful  completion  of the  offering  of  Common Stock  made  hereby to
partially fund  the  Mergers. FRB  approval  was  received on  March  13,  1996.
Applicable  regulations  require  a  waiting  period  following  receipt  of FRB
approval prior to  consummation of the  Mergers, which period  has expired.  The
Mergers  were approved by the shareholders of  First State Bank and Border Bank,
as required by law, at meetings held on April 23, 1996.
 
    Members of senior  management of Texas  State Bank, and  Texas State  Bank's
representatives,  reviewed certain  information concerning First  State Bank and
Border Bank. This review included all loans  on the First State Bank and  Border
Bank  watch lists, a substantial proportion of the loans to borrowers with other
large lines of  credit and selected  other loans in  each bank's portfolio.  The
Company's  examinations  were  made  using  criteria,  analyses  and  collateral
evaluations that the Company  has traditionally used in  the ordinary course  of
its business.
 
    First  State Bank  and Border  Bank have each  entered into  a Memorandum of
Understanding with the  Banking Department,  pursuant to which  each bank  among
other  things,  agrees  to  (i)  develop and  follow  policies  related  to loan
documentation and review,  (ii) increase (and  continue monitoring the  adequacy
of)  each  bank's  loan  valuation  reserve, and  (iii)  review  of  each bank's
investment and  funds  management  policies.  The  Banking  Department  reviewed
compliance  with the First State Bank Memorandum  of Understanding as part of an
examination of  First State  Bank, and  the FDIC  reviewed compliance  with  the
Border  Bank Memorandum  of Understanding  as part  of an  examination of Border
Bank. The  regulatory  authorities  in  each  case  concluded  that  there  were
deficiencies  in compliance  with the  Memorandum applicable  to each  Bank, and
required that First State  Bank and Border Bank  management further address  the
deficiencies  identified in  the Memoranda.  Prior to  entering into  the Merger
Agreements, First  State Bank  and  Border Bank  began to  implement  additional
correction  efforts,  including retaining  an  outside consultant  to  assist in
documentation and policy  reviews for First  State Bank and  Border Bank.  Texas
State  Bank management  believes that the  implementation of  Texas State Bank's
policies and  procedures, and  the application  of Texas  State Bank's  internal
controls,  make it unlikely that the deficiencies identified in the Memoranda of
Understanding will be  repeated, although  there can  be no  certainty that  all
deficiencies  will  be adequately  addressed to  the satisfaction  of applicable
regulatory
 
                                       15
<PAGE>
authorities. If  the  problems  addressed  in  the  Memoranda  of  Understanding
persist,  they could adversely affect the  future operations of the Company. See
"Risk Factors -- Risks of the Mergers -- Compliance and Management."
 
    Following the Mergers, (i) all  lending at the facilities formerly  operated
by  First State Bank and  Border Bank will be  conducted pursuant to Texas State
Bank's policies and under  the supervision of Texas  State Bank's Chief  Lending
Officer,  Frank A. Kavanagh,  (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) following conversion (which is expected by
Texas Regional management  to occur in  fall 1996) 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 locations
formerly operated as First State Bank and Border Bank facilities, will be  Texas
State  Bank's policies and procedures.  Nonperforming assets and loans presently
past due on the books of First State Bank and Border Bank have been reviewed  by
or on behalf of Texas State Bank and those loans which, in the judgment of Texas
State  Bank, represent probable losses  will be recorded at  zero at the time of
consummation of the Mergers, although  Texas State Bank will nonetheless  pursue
collection  in appropriate circumstances.  At March 31,  1996, the allowance for
loan losses  at First  State Bank  was $4.0  million or  91.7% of  nonperforming
assets  plus accruing  loans 90 days  or more past  due. At March  31, 1996, the
allowance for  loan  losses  at  Border  Bank was  $1.1  million  or  132.2%  of
nonperforming  assets plus accruing loans 90 days  or more past due. At December
31, 1995, the allowance for loan losses at First State Bank was $4.2 million  or
52.4%  of nonperforming assets plus accruing loans  90 days or more past due. At
December 31, 1995, the allowance for loan losses at Border Bank was $1.1 million
or 72.5% of nonperforming assets plus accruing loans 90 days or more past due.
 
THE MERGER AGREEMENTS
 
    The information  contained in  this Prospectus  with respect  to the  Merger
Agreements  is a  summary of the  material provisions of  the Merger Agreements,
and, as  such,  is  qualified  in  its  entirety  by  reference  to  the  Merger
Agreements, which are exhibits to the Registration Statement.
 
    The  Merger Agreements provide for the merger of First State Bank and Border
Bank with and into Texas State Bank. Each of the Mergers is conditioned upon the
closing of the  other. The  total consideration  payable pursuant  to the  First
State  Bank  Agreement is  $79.0 million,  and  the total  consideration payable
pursuant to the Border Bank Agreement is $20.5 million, in each case payable  in
cash. None of the shareholders of First State Bank or Border Bank have exercised
dissenter's rights. Each of the Merger Agreements provides that the Mergers will
terminate at the election of either party in the event that the Mergers have not
been consummated prior to June 30, 1996.
 
    Pending the Closing, First State Bank and Border Bank have agreed to certain
operating limitations and requirements, including an obligation to operate their
businesses  in  accordance  with  reasonably prudent  banking  practices  and in
substantially the  same manner  as conducted  prior to  the date  of the  Merger
Agreements.  If either of the Mergers is not consummated as a result of either a
default by Texas State  Bank or the failure  of certain conditions precedent  to
Texas  State Bank's obligation to close the Mergers, Texas State Bank has agreed
to pay a $65,000 termination fee to each of First State Bank and Border Bank.
 
    The consummation  of  the Mergers  is  subject  to a  number  of  conditions
precedent,  including that regulatory approvals shall have been obtained and not
contested in a formal proceeding, that there shall not be litigation pending  or
threatened  which  might  result  in action  to  restrain,  enjoin,  or prohibit
consummation of the  Mergers, and that  each party shall  have received  certain
fairness  opinions in  form and  content acceptable  to that  party. Texas State
Bank's obligations  are  further  conditioned  on  there  being  no  shareholder
exercising  dissenter's rights and there having  been no material adverse change
in the condition, financial position or  business prospects of First State  Bank
or  Border Bank and that each will  have terminated its existing data processing
services contract on terms and  conditions reasonably acceptable to Texas  State
Bank.  Texas State Bank has reserved the right to waive any applicable condition
to Closing in circumstances deemed appropriate by Texas State Bank management.
 
                                       16
<PAGE>
    One of the  conditions to Texas  State Bank's obligation  to consummate  the
First  State Bank Agreement is that First State  Bank have a net worth as of the
date of Closing (without regard to  the effects of consummation of the  Mergers)
of  not less than $62.0 million. Similarly, one of the conditions to Texas State
Bank's obligation to consummate  the Border Bank Agreement  is that Border  Bank
have  a net worth as of the date of Closing of (without regard to the effects of
consummation of the  Mergers and  without regard  to certain  penalties paid  in
connection with the termination of a data processing services contract) not less
than  $17.3 million. Other  than a dividend  of $500,000 paid  by Border Bank in
January 1996, each of  the Merger Agreements prohibits  payment of dividends  to
shareholders of First State Bank and Border Bank pending Closing.
 
    Pursuant  to each of the Merger  Agreements, Elliott Bottom, the Chairman of
the Board and Chief Executive  Officer of First State  Bank and the Chairman  of
the  Board of Border  Bank, has agreed not  to engage (except  as an employee of
Texas State Bank) in the commercial banking business in Hidalgo, Cameron,  Starr
or  Willacy Counties, Texas, for  a period of three  years following the date of
Closing, except that such obligation shall terminate in the event of a change of
control of a  majority of the  outstanding capital stock  of either Texas  State
Bank  or the  Company. As  of the  date of  Closing, Elliott  Bottom will become
President of  Texas  State Bank's  Mission  banking locations.  His  son,  Brent
Bottom, the President of Border Bank, will become the Chief Executive Officer of
Texas State Bank's Hidalgo banking location.
 
    The  terms  of the  Mergers were  established  in arms'  length negotiations
conducted by  representatives of  Texas State  Bank, and  First State  Bank  and
Border  Bank. In approving the Mergers and  the amounts of the purchase price to
be paid, the  Board of  Directors of  Texas State  Bank considered  a number  of
factors,  including:  (i)  First  State  Bank's  and  Border  Bank's  historical
financial condition, including shareholders'  equity and results of  operations;
(ii)  First State Bank's  and Border Bank's  business, prospects, management and
employees; (iii) current economic and market conditions; (iv) the likelihood  of
completing  a  transaction  with  one  or  more  other  banking  institutions on
comparable  or   more  favorable   terms  (although   no  specific   alternative
transactions  were identified); and (v) the  prospects for growth of Texas State
Bank assuming the  Mergers are  completed. The  Board of  Directors attached  no
specific  relative weights  to these factors  in reaching  its determination. In
addition, the Company has received an  opinion of First Southwest Company as  to
the  fairness  of  the transaction,  from  a  financial point  of  view,  to the
shareholders of the Company. Given the historically strong growth rate for Texas
State Bank and the increasing population in its market area, management believes
that Texas  State  Bank's  prospects  for  growth  in  the  future  are  strong,
notwithstanding whether or not the Mergers are consummated.
 
    It  is anticipated  that the  Mergers, which  are effective  upon filing and
acceptance of  a Certificate  of Merger  with the  Banking Department,  will  be
consummated  contemporaneously with the closing and  funding of the net proceeds
of the offering herein described.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
    Since the public  offering of  the Common Stock  in March  1994, the  Common
Stock  has traded in the Nasdaq National  Market System under the symbol "TRBS."
The following  table shows  (i)  high and  low prices  of  the Common  Stock  as
reported  in the Summary of Activity provided to the Company by The Nasdaq Stock
Market for transactions occurring  on the Nasdaq  National Market System  during
the  past  two years,  and  (ii) the  total number  of  shares involved  in such
transactions. In addition, with respect to periods prior to March 16, 1994,  the
information  is based upon transactions with  respect to which the management of
Texas Regional  had  knowledge of  the  transaction price,  since  during  those
periods  transactions were  reported on  an informal  basis, and  no independent
verification of the transaction prices was made. Therefore, during periods prior
to March 16, 1994, the  prices reported may not be  indicative of the actual  or
market value of the Common Stock.

    The Company  paid no  dividends on  its  Common Stock  prior to  June  1994.
Beginning in June 1994, the Company paid a quarterly dividend of $0.08 per share
of  its Common Stock. During 1995,  the Company increased its quarterly dividend
to $0.10 per share, and  currently intends to continue  to pay such dividend  in
the  foreseeable future.  On March  12, 1996,  the Company's  Board of Directors
declared a dividend of $0.10 per  share of Common Stock payable to  shareholders
of record as of April 8, 1996.
 
    The  final determination of  the timing, amount and  payment of dividends on
the Common Stock is at  the discretion of the  Company's Board of Directors  and
will   depend   on  conditions   then   existing,  including   Texas  Regional's
profitability, liquidity, financial  condition, capital  requirements and  other
relevant  factors, including regulatory restrictions  applicable to the Company.
The Company's principal source of the funds to pay dividends on the Common Stock
is dividends from Texas State Bank. The payment of dividends by Texas State Bank
is subject to certain  restrictions imposed by federal  and state banking  laws,
regulations  and authorities. At  March 31, 1996, an  aggregate of $14.6 million
was available for  payment of dividends  by the  Bank to the  Company under  the
applicable  limitations  and  without  regulatory  approval.  See  "Business  --
Regulation and Supervision."

months ended March 31, 1996,  combine the historical consolidated balance  sheet
of  the Company and the historical balance sheets of First State Bank and Border
Bank at March 31, 1996, as if the Mergers had been effective on March 31,  1996.
Similarly, the following unaudited pro forma combined condensed balance sheet at
December  31, 1995, and pro forma combined condensed statement of income for the
year ended December 31, 1995, combine the historical consolidated balance  sheet
of  the Company and the historical balance sheets of First State Bank and Border

1995.  The Mergers  are accounted for  under the purchase  method of accounting,
after giving effect to  the pro forma adjustments  and assumptions described  in
the  accompanying notes. Under  this method of accounting,  which is required by
generally accepted accounting principles, assets and liabilities of First  State
Bank  and  Border  Bank are  adjusted  to  their fair  values  (as  estimated by
management of the Company) and combined  with the recorded values of the  assets
and  liabilities of  the Company.  This pro  forma combined  condensed financial
information should  be  read  in  conjunction  with  the  financial  information
appearing under "Texas Regional Bancshares, Inc. Selected Consolidated Financial
Information"  and the  consolidated financial  statements of  the Company, First
State Bank and Border Bank, including  the notes thereto, included elsewhere  in
this Prospectus. See "Index to Financial Statements."
 
    The following unaudited pro forma combined condensed statement of income for
the  three months  ended March  31, 1996  assumes the  Mergers and  the RGC/Roma
Branch Acquisitions occurred January 1,  1995. The unaudited pro forma  combined
condensed  statement of income for the year ended December 31, 1995 also assumes
the Mergers  and the  RGC/Roma  Branch Acquisitions  occurred January  1,  1995.
Intangibles  arising from the  Mergers and the  RGC/Roma Branch Acquisitions are
approximately $19.7  million  and  $4.1 million,  respectively.  The  pro  forma
adjustments  reflect the amortization of the core deposit premium over a 10-year
period, the fixed maturity deposit premium over a 3-year period and the goodwill
intangible over a 15-year period.
 
    The pro forma combined  condensed financial information  is not intended  to
present the results that would have actually occurred if the Mergers had been in
effect  on the assumed dates and for  the assumed periods. These results are not
necessarily indicative of the results which may be obtained in the future.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    The  following  discussion  provides  additional  information  regarding the
financial condition and the  results of operations for  the Company for each  of
the  three months ended March 31, 1996 and 1995, and for each of the years ended
December 31, 1995, 1994 and 1993. This discussion should be read in  conjunction
with  the consolidated financial statements of the Company and the notes thereto
appearing elsewhere in this Prospectus. See "Texas Regional Bancshares, Inc. Pro
Forma Combined  Condensed  Financial  Information"  for  additional  information
regarding  the effects on the  Company of consummation of  the Mergers. The data
presented for the three-month  periods ended March 31,  1996 and March 31,  1995
are  derived  from unaudited  consolidated interim  financial statements  of the
Company and include, in the opinion of management, all adjustments necessary  to
present fairly the data for such periods.
 
SELECTED CONSOLIDATED FINANCIAL INFORMATION
 
    Net  income for the  three months ended  March 31, 1996  was $2.6 million or
$0.41 per  share, reflecting  a net  increase of  $567,000 or  $0.09 per  share,
compared  to net income of $2.0 million or  $0.32 per share for the three months
ended March 31, 1995 and reflects a net increase of $134,000 or $0.02 per  share
compared  to net income of $2.4 million or  $0.39 per share for the three months
ended December 31, 1995. Earnings performance  for the three months ended  March
31,  1996 compared to the  three months ended March  31, 1995 reflected gains in
net interest income and an increase  in noninterest income, partially offset  by
an  increase in noninterest  expense. Earnings performance  for the three months
ended March 31, 1996 compared to three months ended December 31, 1995  reflected
gains  in net  interest income and  an increase in  noninterest income partially
offset by an  increase in  noninterest expense. Net  income for  the year  ended
December 31, 1995 was $8.7 million, reflecting a net increase of $1.5 million or
a  21.4% increase  compared to  net income  of $7.2  million for  the year ended
December 31, 1994. The earnings per share  of $1.40 for the year ended  December
31,  1995 increased $0.24 or  20.7% compared to the  earnings per share of $1.16
for the year ended  December 31, 1994. Earnings  performance for the year  ended
December  31, 1995  reflected gains  in net interest  income and  an increase in
noninterest income. These positive factors were partially offset by an  increase
in  provision  for  loan  losses  and  noninterest  expenses.  A  more  detailed
description of  the results  of  operations is  included  in the  material  that
follows.
 
    During   August  1995,  Texas  State  Bank  completed  the  RGC/Roma  Branch
Acquisitions which  included the  purchase of  $43.7 million  in loans  and  the
assumption  of  approximately  $79.7  million in  deposit  liabilities  of these
banking locations. This transaction was accounted for as a purchase;  therefore,
the  results of  operations of  the two  banking locations  are included  in the
consolidated financial statements of the  Company from the date of  acquisition.
Purchase  accounting adjustments for the purchase of loans and the assumption of
deposit liabilities of these banking locations were immaterial.
 
    On March 31, 1992,  the Company acquired, through  merger, Mid Valley  Bank,
Weslaco, Texas. Simultaneously with the acquisition of Mid Valley Bank, both the
surviving  bank in that merger transaction  and Harlingen State Bank, Harlingen,
Texas, a subsidiary of the  Company, merged with and  into Texas State Bank  and
the  former Weslaco and Harlingen banks  became banking locations of Texas State
Bank. The Mid Valley Bank merger was accounted for under the purchase method  of
accounting.  Accordingly, certain income statement and balance sheet comparisons
during calendar 1991 and 1992 and  at year-end 1991 and 1992, respectively,  may
not be appropriate.
 
                       ANALYSIS OF RESULTS OF OPERATIONS
 
NET INTEREST INCOME
 
    Net  interest income is the difference between interest earned on assets and
interest expense incurred  for the  funds supporting those  assets. The  largest
category  of earning  assets consists of  loans. The second  largest category of
earning assets is  investment securities,  followed by federal  funds sold.  For
 
                                       28
<PAGE>
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.
 
    Earning  assets  are  financed  by  consumer  and  commercial  deposits  and
short-term  borrowings. In addition to these interest-bearing funds, assets also
are  supported   by  interest-free   funds,   primarily  demand   deposits   and
shareholders'   equity.  Variations  in  the  volume   and  mix  of  assets  and
liabilities,  and  their  relative  sensitivity  to  interest  rate   movements,
determine changes in net interest income.
 
    Taxable-equivalent net interest income was $7.9 million for the three months
ended March 31, 1996, an increase of $1.4 million or 21.7% compared to the three
months  ended March 31, 1995 of $6.5  million. The interest rate margin of 5.38%
for the three months ended March 31, 1996 reflects a decrease of 16 basis points
compared to 5.54% for the three months ended March 31, 1995. The increase in net
interest income for the three months ended March 31, 1996 compared to the  three
months  ended March 31, 1995  was primarily attributable to  the increase in the
volume  of  interest-earning  assets  exceeding   the  increase  in  volume   of
interest-bearing  liabilities and the change in  the mix of earnings assets. The
increase in  net interest  income for  the  three months  ended March  31,  1996
compared  to three months ended December  31, 1995 was primarily attributable to
the change in the mix of  interest-earning assets. The average loan balance  for
the  three months ended March 31, 1996 of $457.4 million increased $44.6 million
or 10.8%  compared  to the  average  loan balance  for  the three  months  ended
December  31, 1995.  The increase  in the  average balance  of loans outstanding
improved earnings. Average  total interest-earning assets  for the three  months
ended  March 31, 1996 of $590.5 million increased $16.4 million or 2.9% compared
to the average total interest-earning assets balance for the three months  ended
December 31, 1995.
 
    Taxable-equivalent  net interest income was $27.8 million for the year ended
December 31, 1995, an  increase of $4.7  million or 20.3%  compared to the  year
ended  December 31,  1994, and taxable-equivalent  net interest  income of $23.1
million for the year  ended December 31, 1994,  increased $3.7 million or  19.3%
compared  to the year ended December 31,  1993. Both net interest income and the
yield on earning  assets were  reduced by  interest foregone  on nonaccrual  and
renegotiated  loans. If interest on those loans had been accrued at the original
contractual rates, additional interest income would have approximated  $247,000,
$476,000,  and $149,000 for  the years ended  December 31, 1995,  1994 and 1993,
respectively.
 
    The net yield on total interest-earning assets, also referred to as interest
rate margin, represents net interest income divided by average  interest-earning
assets.  Since a  significant portion of  the Company's funding  is derived from
interest-free sources, primarily demand  deposits and shareholders' equity,  the
effective   rate  paid  for   all  funds  is   lower  than  the   rate  paid  on
interest-bearing liabilities  alone. As  the  following table  illustrates,  the
interest  rate  margin  of 5.38%  for  the  three months  ended  March  31, 1996
decreased 16 basis points compared to 5.54% for the three months ended March 31,
1995 and increased 10 basis points compared to 5.28% for the three months  ended
December  31, 1995. As the following table illustrates, the interest rate margin
of 5.33% for the year ended December 31, 1995 increased 21 basis points compared
to 5.12% for the year ended December 31, 1994 while the interest rate margin  of
5.12% for the year ended December 31, 1994 increased 28 basis points compared to
4.84% for the year ended December 31, 1993.
 
    The  decrease in the interest  rate margin for the  three months ended March
31, 1996 is  reflective of the  shift in the  mix of interest-bearing  deposits.
Average  time deposits of  $296.7 million for  the three months  ended March 31,
1996 increased $83.9 million or 39.4%  compared to $212.9 million for the  three
months  ended March 31,  1995. The rate  on average time  deposits for the three
months ended March 31, 1996 of 5.55% increased 50 basis points or 9.9%  compared
to the 5.05% rate for the three months ended March 31, 1995.
 
    The  increase in the  interest rate margin  for the year  ended December 31,
1995 is reflective of the shift in  the mix of interest-earning assets to  loans
from  lower yielding investment securities,  including federal funds sold, which
contributed to an increase in yield on interest-earning assets during the  year.
 
                                       29
<PAGE>
The  mix of interest-earning assets was changed by total average loans of $370.3
million increasing $61.2 million or  19.8%, total average investment  securities
of  $131.0 million increasing $967,000 or 0.7% and average federal funds sold of
$19.8 million  increasing $8.3  million or  72.4%. The  increase in  loan  yield
reflects  the general  increase in  average interest  rates in  1995 compared to
1994. The increase in investment  securities yield resulted from lower  yielding
investment  securities maturing and the reinvesting  of the proceeds into higher
yields. The increase in interest on deposits during the year ended December  31,
1995  resulted primarily from increased volume  and the higher average rate paid
compared to the previous year.
 
    The following tables  present for  the three  months ended  March 31,  1996,
December  31, 1995 and March 31, 1995, and for the last three calendar years the
total dollar amount of interest income from average interest-earning assets  and
the  resultant  yields,  reported on  a  tax-equivalent  basis, as  well  as the
interest-bearing liabilities,  expressed  both  in dollars  and  rates.  Average
balances  are derived from average  daily balances and the  yields and costs are
established by dividing income or expense by the average balance of the asset or
liability. Income  and  yield  on interest-earning  assets  include  amounts  to
convert  tax-exempt  income  to  a  taxable-equivalent  basis,  assuming  a  35%
effective income tax rate for 1996 and a 34% effective income tax rate for 1995.

  (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 35% effective  federal income tax rate
      for 1996 and a 34% effective federal income tax rate for 1995).

    The  following table  presents the  effects of  changes in  volume, rate and
rate/volume on  interest income  and interest  expense for  major categories  of
interest-earning  assets and interest-bearing  liabilities. Nonaccrual loans are
included in assets,  thereby reducing yields  (see "Nonperforming Assets").  The
allocation  of the rate/volume variance has been made pro-rata on the percentage
that volume and rate variances produce in each category.

PROVISION FOR LOAN LOSSES
 
    The  provision for loan losses for the  three months ended March 31, 1996 of
$461,000 reflects an increase of $95,000  or 26.0% compared to $366,000 for  the
three months ended March 31, 1995 and was primarily attributable to loan growth.
 
    The  provision for loan losses for the year ended December 31, 1995 was $1.7
million, an increase of  $600,000 or 55.3%  from the $1.1  million for the  year
ended  December  31, 1994.  The provision  for  loan losses  for the  year ended
December 31, 1994  of $1.1 million  reflects an increase  of $693,000 or  176.8%
from  the $392,000  provision for  loan losses for  the year  ended December 31,
1993. Provisions for  loan losses  are charged to  earnings to  bring the  total
allowance  for loan losses to a level  deemed appropriate by management based on
such factors as historical experience, the volume and type of lending  conducted
by  the  Company,  the  amount  of  nonperforming  assets,  regulatory policies,
generally  accepted   accounting   principles,  general   economic   conditions,
particularly  as they  relate to the  Company's lending area,  and other factors
related to the collectibility of the  Company's loan portfolio. The increase  in
the  provision for the year  ended December 31, 1995,  compared to the provision
for the year ended December 31, 1994, was primarily attributable to loan  growth
of  $110.9 million and net charge-offs of  $1.1 million. See "Allowance for Loan
Losses."
 
    In January  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". In management's opinion, the  adoption
of  Statement  114 and  Statement  118 did  not have  a  material effect  on the
Company's financial position or results of operations.

NONINTEREST INCOME
 
    Noninterest income for the three months ended March 31, 1996 of $1.9 million
increased $356,000 or 22.4% compared to $1.6 million for the three months  ended
March  31, 1995 and increased $217,000 or 12.6% compared to $1.7 million for the
three months ended December 31, 1995. The increase in Noninterest income for the
three months ended March 31, 1996 compared  to the three months ended March  31,
1995  is primarily attributable  to the increased fee  income from Total Service
Charges, Trust Service Fees  and Data Processing Service  Fees. The increase  in
Total  Service  Charges  was impacted  by  an  increase in  activity  levels and
additional volume. The increase in Trust Service Fees for the three months ended
March 31, 1996 compared to three months ended March 31, 1995 is attributable  to
increases  in both  the number of  trust accounts  and the book  value of assets
managed. The book value of assets managed at March 31, 1996 and 1995 was  $257.2
million and $205.0 million, respectively. Assets held by the trust department of
the Bank in fiduciary or agency capacities are not assets of the Company and are
not included in the consolidated balance sheets. The increase in Data Processing
Service  Fees for the three months ended March 31, 1996 compared to three months
ended March 31, 1995 is attributable to an increased volume of business.
 
    Noninterest income of  $6.5 million  for the  year ended  December 31,  1995
increased $746,000 or 12.9% compared to $5.8 million for the year ended December
31, 1994, and noninterest income of $5.8 million for the year ended December 31,
1994  increased $740,000 or  14.7% compared to  $5.0 million for  the year ended
December 31, 1993. All  categories of noninterest  income, except Other  Service
Charges  and  Net  Investment  Securities Gains  (Losses),  for  the  year ended
December 31, 1995, increased when compared to the year ended December 31,  1994.
Total  Service Charges  of $4.3  million for  the year  ended December  31, 1995
increased $392,000 or 10.0%  compared to the year  ended December 31, 1994,  and
Total  Service Charges  of $3.9  million for the  year ended  December 31, 1994,
increased $646,000 or 19.6%  compared to the year  ended December 31, 1993.  The
increase  in Total Service Charges  for the years ended  December 31, 1995, 1994
and 1993 is attributable  to increased account transaction  fees as a result  of
the  deposit growth  experienced by  the Company.  The decline  in Other Service
Charges for the year ended December 31, 1995 compared to the year ended December
31, 1994 was primarily attributable to  a decrease in foreign currency  exchange
fees. The recent events in Mexico, primarily the peso devaluation, have resulted
in a decrease in volume and spread on peso exchange fee activity.
 
    Trust  Service Fees  of $1.3  million for the  year ended  December 31, 1995
increased $95,000 or 8.2% compared to  $1.2 million for the year ended  December
31, 1994, and Trust Service Fees of $1.2 million for the year ended December 31,
1994  increased $74,000  or 6.8%  compared to  $1.1 million  for the  year ended
December 31, 1993. The increase in Trust Service Fees in each of years 1995  and
1994  is attributable to increases in both  the number of trust accounts and the
book value of assets managed. The book  value of assets managed at December  31,
1995  and 1994 was $237.4 million  and $192.4 million, respectively. Assets held
by the trust department of  the Bank in fiduciary  or agency capacities are  not
assets of the Company and are not included in the consolidated balance sheets.
 
    Net  Investment Securities Gains (Losses) was  ($111,000) for the year ended
December 31, 1995, compared to  an $8,000 gain for  the year ended December  31,
1994.  The decrease was primarily attributable to a $99,000 loss recorded on the
sale of two bonds.
 
    Other operating income  of $601,000  for the  year ended  December 31,  1995
increased $192,000 or 46.9% compared to $409,000 for the year ended December 31,
1994 and other operating income of $409,000 for the year ended December 31, 1994
increased $27,000 or 7.1% compared to year ended December 31, 1993.

NONINTEREST EXPENSE
 
    Noninterest  expense  for the  three  months ended  March  31, 1996  of $5.3
million increased $720,000 or 15.7% compared to the three months ended March 31,
1995 of $4.6 million and increased $279,000 or 5.5% compared to the three months
ended December 31, 1995 of $5.0 million. The increase for the three months ended
March 31, 1996 compared to the three  months ended March 31, 1995 and the  three
months  ended December  31, 1995  were primarily  attributable to  the increased
volume of business conducted by the Company.
 
    The largest category of noninterest expense, Salaries and Employee  Benefits
("Personnel"),  of  $2.7  million for  the  three  months ended  March  31, 1996
increased $479,000 or 21.2%  compared to the three  months ended March 31,  1995
and  $178,000 or  7.0% compared  to the  three months  ended December  31, 1995.
Personnel expense increased for the three  months ended March 31, 1996  compared
to  the three months ended  March 31, 1995 primarily  due to staffing increases,
including the staff acquired  as a result of  the RGC/Roma Branch  Acquisitions,
staff  for the  Company's second banking  location in Weslaco,  Texas, (the "New
Weslaco Banking Location")  and increases  in payroll  taxes, medical  insurance
premiums and pension expenses for all employees. Personnel expense increased for
the  three  months ended  March  31, 1996  compared  to the  three  months ended
December 31,  1995,  primarily due  to  staffing increases,  including  staffing
increases  associated with the  Company's New Weslaco  Banking Location. The New
Weslaco Banking Location opened in February 1996.
 
    Net Occupancy expense of $317,000 for the three months ended March 31,  1996
increased $64,000 or 25.3% compared to $253,000 for the three months ended March
31,  1995 and $38,000 or  13.6% compared to $279,000  for the three months ended
December 31, 1995. The Net Occupancy expense increase for the three months ended
March 31, 1996 compared to  the three months ended  March 31, 1995 is  primarily
due to the occupancy expenses associated with the RGC/Roma Branch Acquisitions.
 
    Equipment  expense of  $643,000 for  the three  months ended  March 31, 1996
increased $212,000 or  49.2% compared  to $431,000  for the  three months  ended
March  31, 1995 and $79,000 or 14.0% compared to the three months ended December
31, 1995. Equipment expense increased for the three months ended March 31,  1996
as  compared to the three months ended  March 31, 1995 primarily due to expenses
associated with the  RGC/Roma Branch  Acquisitions and the  New Weslaco  Banking
Location.
 
    Noninterest  expense of $19.0  million for the year  ended December 31, 1995
increased $2.5 million  or 15.0% compared  to $16.5 million  for the year  ended
December  31, 1994, and noninterest expense of  $16.5 million for the year ended
December  31,   1994   increased   $2.0   million   or   13.7%   compared   with
 
                                       37
<PAGE>
$14.5  million for  the year  ended December 31,  1993. These  increases for the
years ended  December 31,  1995  and 1994  were  primarily attributable  to  the
increased volume of business conducted by the Company.
 
    Personnel  expense of  $9.6 million  for the  year ended  December 31, 1995,
increased $1.5 million or 19.3% compared to year ended December 31, 1994  levels
of  $8.0 million. Personnel expense of $8.0  million for the year ended December
31, 1994 increased  $217,000 or 2.8%  compared to year  ended December 31,  1993
levels  of $7.8 million. Personnel expense increased for the year ended December
31, 1995 primarily  due to  staffing increases, including  the additional  staff
acquired  as a  result of  the RGC/ Roma  Branch Acquisitions,  and increases in
payroll  taxes,  medical  insurance  premiums  and  pension  expenses  for   all
employees.
 
    Net  Occupancy expense of $1.1 million for  the year ended December 31, 1995
increased $108,000 or 11.2% compared to $961,000 for the year ended December 31,
1994, and net occupancy expense of $961,000 for the year ended December 31, 1994
increased $141,000 or 17.2% when compared to a net occupancy expense of $820,000
for the year ended December 31, 1993.  The increase for the year ended  December
31, 1995 is primarily attributable to the occupancy expenses associated with the
RGC/Roma Branch Acquisitions.
 
    Equipment  expense  of $2.0  million for  the year  ended December  31, 1995
increased $380,000 or 23.1% compared to $1.6 million for the year ended December
31, 1994 and equipment expense of $1.6  million for the year ended December  31,
1994  increased $282,000 or 20.6%  when compared with $1.4  million for the year
ended December 31, 1993.  The equipment expense increase  noted during the  year
ended  December 31, 1995 is primarily  attributable to equipment obtained in the
RGC/Roma Branch Acquisitions  and equipment  acquired to  service the  Company's
increasing customer base.
 
    Other Real Estate (Income) Expense, Net includes rent income from foreclosed
properties,  gain or  loss on  sale of other  real estate  properties and direct
expenses of foreclosed real estate  including property taxes, maintenance  costs
and write-downs. Write-downs of other real estate are required if the fair value
of  an  asset acquired  in a  loan foreclosure  subsequently declines  below its
carrying value. Other Real Estate (Income) Expense, Net of $107,000 for the year
ended December 31, 1995 increased $32,000 or 42.7% when compared to $75,000  net
expense  for  the  year ended  December  31,  1994. Other  Real  Estate (Income)
Expense, Net  of  $75,000 net  expense  for the  year  ended December  31,  1994
decreased  $403,000 or 122.9% compared to $328,000 net income for the year ended
December 31, 1993. The increased expense during the year ended December 31, 1995
is primarily attributable to commissions paid on new lease agreements on  rental
property  included in Other  Real Estate. Management  is actively seeking buyers
for all Other Real Estate and is of the opinion that the carrying value of Other
Real Estate approximates its estimated fair value less estimated closing costs.
 
    Advertising and  Public Relations  expense of  $772,000 for  the year  ended
December  31, 1995 increased $79,000 or 11.4%  compared to $693,000 for the year
ended December  31,  1994. The  increase  in advertising  and  public  relations
expense  is primarily  attributable to  a new  marketing program  and additional
advertising in the service area acquired in the RGC/Roma Branch Acquisitions.
 
    FDIC insurance of $540,000 for the  year ended December 31, 1995,  decreased
$433,000  or 44.5% compared to $973,000 for the year ended December 31, 1994 due
to a rebate and a premium rate reduction.  On August 8, 1995, the FDIC Board  of
Directors voted to reduce the deposit insurance premiums paid by most members of
the Bank Insurance Fund, effective as of June 1, 1995. As a result, the overpaid
assessments  for the period June 1 to  September 30, 1995 and interest (totaling
$297,000) were refunded on September 15, 1995. The Company continues to  receive
the  most favorable risk  classification for purposes  of determining the annual
deposit insurance assessment rate, although there  can be no assurance that  the
Company will continue in the most favorable risk classification in the future.
 
    The  increase  in Other  Losses  represents additional  losses  sustained on
overdraft accounts and the costs of settlement during the period ending December
31, 1995 of certain litigation.

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
    In  December 1990, the Financial  Accounting Standards Board ("FASB") issued
Statement  of  Financial  Accounting   Standards  No.  106  ("Statement   106"),
"Employers'  Accounting for Postretirement Benefits  Other Than Pensions", which
is effective for fiscal years beginning  after December 15, 1992. Statement  106
requires  companies  that  have  postretirement  benefit  plans  to  accrue  the
estimated cost of  providing those benefits  to an employee  and the  employee's
beneficiaries  and covered  dependents. The  Company does  not presently provide
postretirement benefits other  than the  KSOP Plan,  which is  available to  all
eligible  employees,  and  a  nonqualified deferred  compensation  plan  for the
benefit of Glen E. Roney, Chairman  of the Board, President and Chief  Executive
Officer.
 
INCOME TAX
 
    The Company recorded income tax expense of $1.3 million for the three months
ended  March 31, 1996 compared to $1.1  million for three months ended March 31,
1995. The increase in income  tax expense for the  three months ended March  31,
1996  is due primarily to  an increased level of  pretax income during the three
months ended March 31, 1996.
 
    The Company recorded income tax expense  of $4.7 million for the year  ended
December 31, 1995 compared to $3.9 million for the year ended December 31, 1994.
The  increase in income tax expense for the  year ended December 31, 1995 is due
primarily to an increased level of pretax income during the year ended  December
31, 1995.

    The  Texas franchise tax is based in part  on capital and in part on federal
taxable income with certain  modifications. A portion of  the tax is accrued  in
the  year in which the income to which it relates is earned, even though the tax
constitutes a fee for the privilege of doing business in a succeeding period and
is payable in that period. The  Company recorded Texas franchise tax expense  of
$217,000,  $207,000 and $149,000 for the years ended December 31, 1995, 1994 and
1993, respectively.
 
NET INCOME
 
    Net income was  $2.6 million  and $2.0 million  for the  three months  ended
March  31, 1996 and 1995, respectively, and  $8.7 million, $7.2 million and $6.0
million for the years ended December 31, 1995, 1994 and 1993, respectively.
 
                        ANALYSIS OF FINANCIAL CONDITION
 
BALANCE SHEET COMPOSITION
 
    The Company continues  to experience  growth in total  assets, deposits  and
loans  attributable in the opinion of management, in part to the vitality of the
Rio Grande Valley economy and in part to the RGC/ Roma Branch Acquisitions.  The
recent  devaluation of the Mexican peso relative  to the U.S. dollar has reduced
retail sales  to  Mexican nationals.  However,  the  effects of  NAFTA  and  the
devaluation  have also  increased cross-border trade  and industrial development
including activity at  twin manufacturing  plants located  on each  side of  the
border  (referred  to  as  maquiladoras) which  benefit  the  Rio  Grande Valley
economy. Management does not believe that the recent Mexican financial  problems
will materially adversely affect the Company's growth and earnings prospects.
 
    Average  interest-earning assets of $590.5 for  the three months ended March
31, 1996 increased $115.9  million or 24.4% compared  to $474.6 million for  the
three  months ended March 31, 1995 and  $16.4 million or 2.9% compared to $574.0
million for the  three months  ended December 31,  1995. Management's  continued
focus  on lending  has resulted  in average  loans increasing  $113.1 million or
32.9% to $457.4 million for  the three months ended  March 31, 1996 compared  to
the  three months  ended March  31, 1995 level  of $344.3  million and increased
$44.6 million or  10.8% compared  to the three  months ended  December 31,  1995
level  of $412.8 million. Total average  investments decreased $55,000 to $120.4
million for the three months ended March 31, 1996 compared to three months ended
March 31, 1995  level of  $120.5 million and  decreased $24.1  million or  16.7%
compared  to the three months  ended December 31, 1995  level of $144.6 million.
Total average assets increased $125.7 million or 23.7% to $655.6 million for the
three months ended March 31, 1996 compared to three months ended March 31,  1995
level  of $529.9 million and $20.7 million  or 3.3% compared to the three months
ended December 31, 1995 level of $634.9 million.
 
    Average interest-earning assets of $521.1 million increased $70.5 million or
15.7% for the year ended  December 31, 1995 compared  to $450.6 million for  the
year  ended December  31, 1994  and $51.3  million or  12.8% for  the year ended
December 31, 1994  compared to $399.3  million for the  year ended December  31,
1993.  Management's continued  focus on  lending has  resulted in  average loans
increasing $61.2 million or 19.8% to $370.3 million for the year ended  December
31,  1995 compared to December 31, 1994  levels of $309.0 million, while average
investment securities of $131.0 million increased $967,000 or 0.7% for the  year
ended  December 31, 1995 compared to December 31, 1994 levels of $130.0 million.
Total average assets increased $73.7 million or 14.6% to $577.9 million for  the
year  ended December  31, 1995  compared to December  31, 1994  levels and $56.1
million or 12.5% to $504.2 million for the year ended December 31, 1994 compared
to December 31, 1993 levels of $448.1 million.
 
    Average interest-bearing deposits increased $97.6 million or 26.2% to $469.9
million for the three months ended March  31, 1996 compared to the three  months
ended  March 31, 1995 level of $372.3 million and $15.6 million or 3.4% compared
to the three  months ended December  31, 1995 level  of $454.2 million.  Average
total demand deposits increased $20.7 million or 21.6% to $116.6 million for the
three  months ended March 31, 1996 compared  to the three months ended March 31,
1995 level  of $95.8  million and  increased $3.3  million or  2.9% compared  to
$113.2 million for the three months ended December 31, 1995.

    Average interest-bearing deposits increased $54.3 million or 15.3% to $409.5
million for the year ended December 31, 1995 compared to the year ended December
31,  1994 level of $355.2 million.  Average total demand deposits also increased
$10.0 million or 10.7% for  the year ended December  31, 1995 to $103.8  million
compared to the year ended December 31, 1994 level of $93.8 million partially as
a  result of the increase in public  funds from several local municipalities and
independent school  districts.  The  Company has  a  stable  noninterest-bearing
source  of funds as reflected in the ratio of average demand deposits to average
total deposits for years ended December 31, 1995, 1994 and 1993 of 20.2%, 20.9%,
and 20.6%, respectively.

three months ended March 31, 1996 and 1995, and during the last three years:

CASH AND DUE FROM BANKS
 
    Texas  State Bank, through its nine  banking locations, offers a broad range
of commercial  banking services  to individuals  and businesses  in its  service
area.  Texas State Bank also acts as a correspondent to a number of banks in its
service  area,   providing  check   clearing,  wire   transfer,  federal   funds
transactions,  loan  participations,  data  processing  and  other correspondent
services. The amount of cash and due from

banks held on any  one day is significantly  influenced by temporary changes  in
cash  items in process of collection. At March 31, 1996, cash and due from banks
was $31.5 million, $5.8  million more than  at March 31,  1995. At December  31,
1995,  cash and  due from  banks was  $30.9 million,  $9.5 million  less than at
December 31, 1994.
 
INVESTMENT SECURITIES
 
    In May 1993, the FASB issued Statement of Financial Accounting Standards No.
115 ("Statement 115"), "Accounting  for Certain Investments  in Debt and  Equity
Securities".  Statement 115  established standards  of financial  accounting and
reporting for investments in equity securities that have a readily  determinable
fair  value and for all investments in debt securities. At acquisition, the 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  consolidated balance sheet  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 consolidated  balance sheet with
unrealized holding  gains  and  losses included  in  earnings.  Investments  not
classified as either Held to Maturity or Trading are classified as Available for
Sale  and  measured  at  fair  value  in  the  consolidated  balance  sheet with
unrealized holding  gains  and  losses  reported  in  a  separate  component  of
shareholders' equity until realized.
 
    Effective December 31, 1993, the Company adopted Statement 115, which caused
various  investment  securities  to be  reclassified  from Held  to  Maturity to
Available for Sale. All treasury and agency  bonds with a maturity of two  years
or  less from December  31, 1993, all  floating rate bonds  and two small equity
securities were  reclassified to  Available for  Sale. During  1994,  management
continued classifying bonds purchased with a final maturity of two years or less
as  Available for Sale.  During 1995, management  has classified bonds purchased
with a final maturity of  three years or less as  Available for Sale. All  other
bonds  have been classified as Held  to Maturity. Future purchases of investment
securities will be classified as Available for Sale or Held to Maturity at  time
of purchase as determined by the investment committee.
 
    On  October 18, 1995, the  FASB decided to grant  to all entities a one-time
opportunity during  the period  from  approximately the  middle of  November  to
December  31, 1995,  to reconsider their  intent and ability  to hold securities
accounted for as Held to Maturity under Statement 115. This opportunity  allowed
entities  to transfer securities from the Held to Maturity category to Available
for Sale or  Trading without calling  into question their  intent to hold  other
debt  securities  to  maturity.  On  December  31,  1995,  the  Bank transferred
approximately $1.5 million in Held to  Maturity securities to the Available  for
Sale  category resulting in  no change to  shareholders' equity per  share. As a
result of this transfer,  all Other Securities are  classified as Available  for
Sale.
 
    At  March 31,  1996 and  1995 and at  December 31,  1995, 1994  and 1993, no
securities were classified as Trading.

LOANS
 
    The Company  manages  its  credit  risk  by  establishing  and  implementing
strategies  and  guidelines  appropriate to  the  characteristics  of borrowers,
industries, geographic locations  and products. Diversification  of risk  within
each  of  these  areas  is  a primary  objective.  Policies  and  procedures are
developed to  ensure that  loan commitments  conform to  current strategies  and
guidelines.  Management continues  to refine  the Company's  credit policies and
procedures to address the risks in  the current and prospective environment  and
to   reflect  management's  current  strategic  focus.  The  credit  process  is
controlled with continuous credit review and analysis, and by review by internal
and external auditors and regulatory authorities. The Company's loans are widely
diversified by borrower and industry group.
 
    The Company has collateral management  policies in place so that  collateral
lending  of  all  types  is  approached, to  the  extent  possible,  on  a basis
consistent with safe and sound standards. Valuation analysis is utilized to take
into consideration  the  potentially  adverse economic  conditions  under  which
liquidation  could  occur.  Collateral  accepted  against  the  commercial  loan
portfolio includes  accounts receivable  and inventory,  marketable  securities,
equipment  and agricultural products. Autos, deeds  of trust, life insurance and
marketable securities  are  accepted  as collateral  for  the  installment  loan
portfolio.
 
    Management  of the  Company believes  that the  Company has  benefitted from
increased loan demand due to passage  of NAFTA and the strong population  growth
in  the Rio Grande  Valley. More recently,  the devaluation of  the Mexican peso
relative to the  U.S. dollar has  reduced retail sales  to residents of  Mexico.
However,   the  effects  of  NAFTA  and  the  devaluation  have  also  increased
cross-border  trade  and  industrial  development  including  activity  at  twin
manufacturing  plants  located  on  each  side of  the  border  (referred  to as
maquiladoras) which benefit the Rio  Grande Valley economy. Management  believes
the  current Mexican financial problems will  not have a material adverse effect
on the Company's growth and earnings prospects.
 
    Total loans at March 31, 1996 of $467.1 million increased $112.6 million  or
31.8%  compared to March  31, 1995 level  of $354.4 million  and increased $16.2
million or  3.6% compared  to December  31, 1995  level of  $450.9 million.  The
increase  in  total  loans  at  March  31,  1996  compared  to  total  loans  at
 
                                       45
<PAGE>
March 31, 1995 is  primarily attributable to  the RGC/Roma Branch  Acquisitions,
funding  a large leveraged employee stock  ownership trust loan and management's
efforts to improve the earnings mix of earning assets by increasing loan volume.
 
    Total loans of $450.9 million for the year ended December 31, 1995 increased
$110.9 million or 32.6% compared to the  year ended December 31, 1994 levels  of
$339.9  million and increased $49.4 million or 17.0% for the year ended December
31, 1994 compared to levels of $290.5 million at December 31, 1993. The increase
in total loans for the year ended December 31, 1995 is primarily attributable to
the RGC/Roma  Branch  Acquisitions, funding  a  large leveraged  employee  stock
ownership  trust loan (hereafter described)  and management's efforts to improve
the earnings mix of  earning assets by increasing  loan volume. The increase  in
Commercial  loans in general, and Commercial-Tax Exempt loans in particular, for
the year ended December 31, 1995 was primarily attributable to the funding of  a
$34.0  million employee  stock ownership trust  loan which  is collateralized by
stock and assets  of the employer  and approximately $27.5  million of cash  and
cash  equivalent assets. Excluding this loan, Total Commercial Loans at December
31, 1995 represented an increase of $10.6 million, or 10.4%, compared to  levels
at  December  31, 1994,  and Total  Loans  at December  31, 1995  represented an
increase of $76.9 million, or 22.6%, compared to levels at December 31, 1994.  A
substantial   portion   of   the   increase   in   loans   classified   as  Real
Estate-Commercial Mortgage loans consists  of loans secured  by real estate  and
other  assets to commercial customers. The increase  in total loans for the year
ended December 31, 1992 is primarily due to the acquisition of Mid Valley  Bank.

1996 and 1995, and at the end of each of the last five years:

    As  shown in  the preceding tables,  loans maturing within  one year totaled
$186.8 million  at March  31, 1996,  and $176.5  million at  year-end 1995.  The
Company's  policy on maturity extensions and  rollovers is based on management's
assessment of individual loans. Approvals for the extension or renewal of  loans
without  reduction  of  principal  for more  than  one  twelve-month  period are
generally avoided, unless  the loans are  fully secured or  are revolving  lines
subject to annual analysis and renewal.

NONPERFORMING ASSETS
 
    The  Bank  has several  procedures  in place  to  assist in  maintaining the
overall quality of  its loan  portfolio. The Bank  has established  underwriting
guidelines  to be followed  by its officers and  monitors its delinquency levels
for any negative or adverse trends,  particularly with respect to credits  which
have total exposures of $10,000 or more.
 
    Nonperforming  assets  consist  of  nonaccrual loans,  loans  for  which the
interest rate has been renegotiated  below originally contracted rates and  real
estate  or other assets that have been  acquired in partial or full satisfaction
of loan obligations. At  March 31, 1996, eight  loan relationships in excess  of
$100,000  totaling  $2.1 million  accounted for  74.8%  of the  total nonaccrual
loans. These eight nonaccrual credits are secured primarily by real estate,  and
management  believes that it is unlikely that any material loss will be incurred
on disposition of the  collateral. The remaining nonaccrual  loans at March  31,
1996 represent loans of less than $100,000 each.
 
    The  Company's policy generally is to place a loan on nonaccrual status when
payment of principal or interest is  contractually past due 90 days, or  earlier
when  concern exists as to the ultimate collection of principal and interest. At
the time a loan is placed on nonaccrual status, interest previously accrued  but
uncollected is reversed and charged against current income.
 
    Loans  which are contractually 90 days or more past due, which are both well
secured or  guaranteed  by financially  responsible  third parties  and  in  the
process of collection, generally are not placed on nonaccrual status. The amount
of such loans past due 90 days or more at March 31, 1996 of $533,000 reflects an
increase  of $227,000 or 74.2% compared to the March 31, 1995 level of $306,000.
The amount of such accruing loans 90 days  or more past due for the years  ended
December  31,  1995,  1994 and  1993  totaled $642,000,  $226,000  and $439,000,
respectively. The  increase  in accruing  loans  90 days  or  more past  due  at
December 31, 1995 as compared to December 31, 1994 is partly attributable to two
credits over $100,000 included in the category, both of which are in the process
of collection.
 
    Nonperforming assets at March 31, 1996 of $4.3 million increased $859,000 or
24.8%  compared to March  31, 1995 of  $3.5 million and  represent 0.7% of total
assets. The increase in nonperforming assets at March 31, 1996 compared to March
31, 1995 is primarily attributable to one large credit of approximately $403,000
which is in the process of collection.
 
    Nonperforming assets of  $3.6 million  at December 31,  1995 decreased  $1.2
million  or  25.5% compared  to December  31,  1994 levels  of $4.8  million and
decreased $138,000 or  2.9% for  the year ended  December 31,  1994 compared  to
December  31, 1993 levels of $5.0  million. Management actively seeks buyers for
all  Other  Real  Estate.  See   "Noninterest  Expense"  above.  The  ratio   of
nonperforming  assets plus accruing loans 90 days  or more past due as a percent
of total loans and other nonperforming assets at December 31, 1995 decreased  to
0.9%  from 1.5%  at December 31,  1994 due  primarily to the  reduction in other
nonperforming assets and the addition of $43.7 million of performing loans  from
the RGC/Roma Branch Acquisitions.
 
    Management  is not aware of any borrower relationships that are not reported
as nonperforming where management has serious  doubts as to the ability of  such
borrowers  to comply  with the  present loan  repayment terms  which would cause
nonperforming assets to increase materially.
 
    Effective January  1,  1995,  the  Company adopted  Statement  114  and  the
amendment  thereof, Statement  118. 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.  See "Texas  Regional Bancshares,  Inc.  Management's
Discussion  and  Analysis  of  Financial Position  and  Results  of Operations--

loans  for which  there was  no related allowance  for loan  losses. The average
level of impaired loans during  the three months ended  March 31, 1996 was  $2.9
million.  The Company recorded interest income  of $77,000 on its impaired loans
during the three months ended March 31, 1996.
 
    At December 31, 1995, the Company had a $2.0 million recorded investment  in
impaired  loans  for which  there was  a  related allowance  for loan  losses of
$172,000. At December 31, 1995, there were no impaired loans for which there was
no related allowance for loan losses. The average level of impaired loans during
the year ended December 31, 1995 was $1.9 million. The Company recorded interest
income of $91,000 on its impaired loans during the year ended December 31, 1995.

    Interest income that would  have been recorded for  the year ended  December
31,  1995  on nonaccrual  and  renegotiated loans  had  such loans  performed in
accordance with their original contractual terms and been outstanding throughout
the year ended December 31, 1995, or since origination, if held for only part of
that year, was approximately $247,000. For the year ended December 31, 1995, the
amount of interest income actually recorded on nonaccrual and restructured loans
was approximately $176,000.
 
    Management regularly reviews  and monitors  the loan  portfolio to  identify
borrowers  experiencing  financial  difficulties. Management  believes  that, at
March 31, 1996 and at December 31, 1995, all such loans had been identified  and
included  in  the  nonaccrual, restructured  or  90  days past  due  loan totals
reflected in the table  above. Management continues  to emphasize maintaining  a
low  level  of nonperforming  assets and  returning  nonperforming assets  to an
earning status.
 
ALLOWANCE FOR LOAN LOSSES
 
    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 experience, 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
 
                                       49
<PAGE>
losses  are charged  off. In  addition, the  loan review  committee of  the Bank
reviews the assessments 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.  The
allowance  for loan losses at March 31,  1996 of $4.9 million increased $895,000
or 22.4% compared to the  March 31, 1995 balance  of $4.0 million and  increased
$348,000  or 7.7% compared to the December 31, 1995 balance of $4.5 million. The
allowance for loan losses at March 31,  1996 is 1.05% of loans outstanding,  net
of  unearned discount. Management believes that the allowance for loan losses at
March 31,  1996,  adequately reflects  the  risks  in the  loan  portfolio.  The
allowance  for  loan  losses  at  December  31,  1995  was  $4.5  million, which
represents an increase of $1.0 million or 29.3% as compared to the allowance for
loan losses at  December 31, 1994.  Management believes that  the allowance  for
loan  losses at  December 31,  1995 adequately  reflects the  risks in  the loan
portfolio. Various regulatory agencies, as an integral part of their examination
process, periodically  review  the Company's  allowance  for loan  losses.  Such
agencies  may require the Company to  recognize additions to the allowance based
on their  judgments  of information  available  to them  at  the time  of  their
examination.
 
    The following table summarizes the activity in the allowance for loan losses
for the three months ended March 31, 1996 and 1995, and for the last five years:

or  23.1% compared to the  March 31, 1995 level  of $476.0 million and increased
$6.3 million or 1.1% compared to December 31, 1995 levels of $579.7 million. The
increase in total deposits from  March 31, 1995 to  March 31, 1996 is  primarily
attributable  to  the RGC/Roma  Branch Acquisitions.  The  $6.3 million  or 1.1%
increase for total  deposits at  March 31, 1996  compared to  total deposits  at

increase in total deposits at December 31, 1995 compared to December 31, 1994 is
primarily    attributable   to   the   RGC/Roma   Branch   Acquisitions.   Total

1995  represented an  increase of  $20.8 million or  20.8% compared  to the year

deposits (consisting of Public Funds Demand Deposits, Public Funds Money  Market
Checking  and Savings and Public  Funds Time Deposits) of  $39.3 million for the
year ended  December 31,  1995  decreased $16.3  million  or 29.3%  compared  to
December  31,  1994 levels  of $55.6  million.  The decline  in public  funds is
primarily due to the loss of a large public fund to a competitor as a result  of
a  competitive  bid in  September  1995. The  Bank  actively seeks  consumer and
commercial deposits,  including deposits  from  correspondent banks  and  public
funds  deposits. The following table presents  the composition of total deposits
at the end of three months ended March 31,  1996 and 1995 and at the end of  the
last three years:

    Mexico is a part of the trade territory of the Company and foreign  deposits
from  Mexican sources have  traditionally been a source  of funding. In December
1994, the Mexican  government announced a  15% devaluation of  the Mexican  peso
relative  to the United States dollar, and  the Mexican peso has since continued
to decline relative to the dollar. The Company does not anticipate any  negative
impact  on foreign deposits  due to these  recent devaluations of  the peso. The
increase in  foreign  deposits is  primarily  attributable to  Mexican  deposits
obtained  with the  RGC/Roma Branch  Acquisitions. The  following table presents
foreign deposits, primarily from  Mexican sources, at March  31, 1996 and  1995,
and at December 31, 1995 and 1994:

LIQUIDITY
 
    Liquidity  management  assures that  adequate  funds are  available  to meet
deposit  withdrawals,  loan  demand   and  maturing  liabilities.   Insufficient
liquidity  can  result  in  higher costs  of  obtaining  funds,  while excessive
liquidity can  lead to  a  decline in  earnings due  to  the cost  of  foregoing
alternative  investments. The  ability to  renew and  acquire additional deposit
liabilities is a major source of  liquidity. The Company's principal sources  of
funds  are  primarily  within the  local  markets  of the  Bank  and  consist of
deposits, interest and  principal payments on  loans and investment  securities,
sales of loans and investment securities and borrowings. See previous discussion
regarding   the  maturity   dates  for  "Loans,"   "Investment  Securities"  and
"Deposits."
 
    Asset liquidity is provided by cash and assets which are readily marketable,
or which can be pledged, or which will mature in the near future. These  include
cash,  federal funds  sold and U.S.  Government-backed securities.  At March 31,
1996,  the  Company's  liquidity  ratio,  defined  as  cash,  U.S.   Government-
 
                                       53
<PAGE>
backed  securities and federal funds sold as a percentage of deposits, was 25.8%
compared to 32.4% at March 31, 1995 and compared to 27.5% at December 31,  1995.
At  December 31, 1995, the Company's liquidity ratio was 27.5% compared to 34.2%
at December 31, 1994 and compared to  36.0% at December 31, 1993. In each  case,
the  Company's liquidity ratio has declined  as a result of management's efforts
to improve the Company's earnings mix by increasing loan volume.
 
    Liability  liquidity  is  provided  by  access  to  core  funding   sources,
principally  various customers' interest-bearing and noninterest-bearing deposit
accounts in the Company's trade area. The  Company does not have or nor does  it
solicit brokered deposits. Federal funds purchased and short-term borrowings are
additional  sources of liquidity.  These sources of  liquidity are short-term in
nature and are  used, as  necessary, to fund  asset growth  and meet  short-term
liquidity needs.
 
    For  the three months ended March 31, 1996, liquidity was enhanced primarily
by net  cash  provided  by  operating  activities  of  $4.1  million,  investing
activities of $641,000 and financing activities of $5.5 million. The increase in
net cash provided by financing activities was primarily attributable to the $6.3
million  net increase in deposits. As a result, net cash and cash equivalents at
March 31, 1996 of $44.7 million increased $10.2 million or 29.6% compared to net
cash and cash equivalents at December 31, 1995 of $34.5 million.
 
    During 1995,  funds for  $79.4  million of  investment purchases  and  $69.5
million  of net loan growth came from  various sources, including a net increase
in deposits of $27.9 million, $12.6 million in proceeds from sale of  investment
securities,  $62.5 million in  proceeds from maturing  investment securities and
$8.7 million of net income.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
requires that  federal  bank  regulatory  authorities  take  "prompt  corrective
action" with respect to any depository institution which does not meet specified
minimum  capital requirements. The applicable regulations establish five capital
levels which require or permit the FRB and other regulatory authorities to  take
supervisory  action. The relevant classifications  range from "well capitalized"
to "critically undercapitalized." The  classifications are generally  determined
by   applicable  ratios  of  the  institution,   including  Tier  I  capital  to
risk-weighted assets, total capital to risk-weighted assets and leverage ratios.
Based on Texas  State Bank's capital  ratios at December  31, 1995, Texas  State
Bank was classified as "well capitalized" under the applicable regulations. As a
result,  the  Company  does  not  believe  that  the  prompt  corrective  action
regulations have any  material effect  on the  activities or  operations of  the
Company or Texas State Bank.
 
    The  principal sources  of liquidity  for the  Company during  1995 were the
proceeds from the 1994 sale of 1.0  million shares of Common Stock and  interest
income  of $338,000 from the Bank. The funds received were used primarily to pay
common stock dividends and other expenses.
 
    The Company is dependent on dividend  and interest income from the Bank  and
the  sale of  stock for its  liquidity. Applicable FRB  regulations provide that
bank holding  companies are  permitted  by regulatory  authorities to  pay  cash
dividends  on  their  common or  preferred  stock if  consolidated  earnings and
consolidated capital are within regulatory guidelines and the Bank is classified
as "well capitalized" for  purposes of FDICIA. See  "Business -- Regulation  and
Supervision" and "Business -- Capital Resources."
 
    The  funds management policy  of the Company  and the Bank  is to maintain a
reasonably balanced position of rate  sensitive assets and liabilities to  avoid
adverse  changes in  net interest income.  Changes in net  interest income occur
when interest rates on loans and  investments change in a different time  period
from  that of  changes in  interest rates  on liabilities,  or when  the mix and
volume of interest-earning assets  and interest-bearing liabilities change.  The
interest rate sensitivity gap represents the dollar amount of difference between
rate  sensitive assets and rate sensitive liabilities within a given time period
("GAP"). A GAP  ratio is determined  by dividing rate  sensitive assets by  rate
sensitive liabilities. A ratio of 1.0 indicates a perfectly matched position, in
which  case the  effect on  net interest income  due to  interest rate movements
would be zero.
 
                                       54
<PAGE>
    Rate sensitive  assets  maturing within  one  year exceeded  rate  sensitive
liabilities  with  comparable maturities  at March  31,  1996 by  $27.0 million.
Management monitors the rate sensitivity GAP on a regular basis and takes  steps
when  appropriate  to  improve the  sensitivity.  The ratio  of  cumulative rate
sensitivity GAP to total assets at a period of twelve months or less was 4.11%.

EFFECTS OF INFLATION
 
    Financial institutions  are  impacted  differently  by  inflation  than  are
industrial  companies.  While industrial  and manufacturing  companies generally
have  significant  investments  in  inventories  and  fixed  assets,   financial
institutions  ordinarily do  not have such  investments. As  a result, financial
institutions are generally  in a  better position than  industrial companies  to
respond  to inflationary trends by monitoring  the spread between interest costs
and interest income yields through adjustments of maturities and interest  rates
of  assets and liabilities. In addition,  inflation tends to increase demand for
loans from financial institutions as industrial companies attempt to maintain  a
constant  level of  goods in  inventory and  assets. As  consumers of  goods and
services, financial institutions are affected  by inflation as prices  increase,
causing  an increase in costs of  salaries, employee benefits, occupancy expense
and similar items.

CAPITAL RESOURCES
 
    Shareholders' equity  at March  31,  1996 of  $64.6 million  increased  $7.2
million  or 12.6%  compared to  the March  31, 1995  level of  $57.3 million and
increased $1.8 million or 2.9% compared to the December 31, 1995 level of  $62.7
million.  The  increase  was  attributable  to  earnings  reduced  primarily  by
dividends paid on Class A Voting Common Stock.
 
    Shareholders' equity of $62.7 million for  the year ended December 31,  1995
reflects  a  net increase  of approximately  $7.0 million  or 12.5%  compared to
shareholders' equity of $55.7 million for the year ended December 31, 1994. This
net increase was primarily attributable to  earnings for 1995. The net  increase
in  shareholders' equity reflects dividends paid on Common Stock of $2.5 million
which included $620,000 declared December 12, 1995 and paid on January 16, 1996.
 
    On March  21,  1994,  the  Board  of Directors  of  the  Company  adopted  a
resolution  calling  for  redemption  on  April  22,  1994  of  all  issued  and
outstanding preferred stock,  including the Company's  First Series  Convertible
Preferred  Stock,  Series  1990  Convertible  Preferred  Stock  and  Series 1991
Convertible Preferred Stock (herein  collectively called the "Preferred  Stock")
at  a redemption price of  $104 per share plus  all accrued and unpaid dividends
through the date fixed for redemption. The Preferred Stock was convertible  into
13.2 shares of Common Stock for each share of Preferred Stock held.
 
    Effective  April 22, 1994,  356 shares of Preferred  Stock were redeemed and
74,172 shares of Preferred  Stock were converted into  979,009 shares of  Common
Stock.
 
    The  risk-based capital standards  as established by the  FRB apply to Texas
Regional and Texas State Bank. The numerator of the risk-based capital ratio for
bank  holding  companies   includes  Tier  I   capital,  consisting  of   common
shareholders'  equity  and  qualifying  cumulative  and  noncumulative perpetual
preferred stock;  and Tier  II  capital, consisting  of other  preferred  stock,
reserve  for  possible  loan  losses  and  certain  subordinated  and  term-debt
securities. Beginning on  December 31, 1993,  goodwill is deducted  from Tier  I
capital.  At no time is Tier II capital  allowed to exceed Tier I capital in the
calculation of total capital. The denominator or asset portion of the risk-based
capital ratio aggregates generic classes of balance sheet and off-balance  sheet
exposures,  each weighted by one of four factors, ranging from 0% to 100%, based
on the relative risk of the exposure class.
 
    Ratio targets are set for both Tier I and total capital (Tier I plus Tier II
capital). The minimum level of  Tier I capital to total  assets is 4.0% and  the
minimum total capital ratio is 8.0%. The FRB has guidelines for a leverage ratio
that  is designed as an  additional evaluation of capital  adequacy of banks and
bank holding companies. The leverage ratio is defined to be the company's Tier I
capital divided by its  quarterly average total assets  less goodwill and  other
intangible  assets. An insured depository  institution is "well capitalized" for
purposes of the  FDICIA if its  Total Risk-Based  Capital Ratio is  equal to  or
greater  than 10.0%, and Tier I Risk-Based  Capital Ratio is equal to or greater
than 6.0%, and Tier I Leverage Capital  Ratio is equal to or greater than  5.0%.
The  Company's  Tier I  Risk-Based Capital  Ratio  was approximately  11.66% and
14.59% at March 31, 1996 and 1995, respectively. The Company's Total  Risk-Based
Capital  Ratio was approximately 12.63%  and 15.63% at March  31, 1996 and 1995,
respectively. The Company's Tier I Leverage  Capital Ratio was 9.07% and  10.56%
at  March  31, 1996  and  1995, respectively.  The  Company's Tier  I Risk-Based
Capital Ratio was approximately 11.70% and 14.71% at December 31, 1995 and 1994,
respectively. The  Company's Total  Risk-Based Capital  Ratio was  approximately
12.64%  and 15.67%  at December 31,  1995 and 1994,  respectively. The Company's
Tier I Leverage Capital  Ratio was 8.96%  and 10.37%, at  December 31, 1995  and
1994,  respectively.  Based  on  capital  ratios,  the  Company  is  within  the
definition of "well capitalized" for FRB purposes at March 31, 1996 and December
31, 1995.

CURRENT ACCOUNTING ISSUES
 
    Effective January  1,  1995,  the  Company adopted  Statement  114  and  the
amendment  thereof, Statement  118. 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 Statement  114, the  Company makes  an assessment  for
impairment  when and while such loans are  on nonaccrual status 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
Company 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  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 collectability of principal.
 
    In management's opinion, the adoption of Statement 114 and Statement 118 did
not have a material effect on the Company's results of operations.
 
    In October 1995, FASB issued Statement of Financial Accounting Standards No.
123 ("Statement 123"), "Accounting for Stock-Based Compensation". Statement  123
establishes   financial  accounting  and  reporting  standards  for  stock-based
employee compensation plans. Statement 123 encourages entities to adopt a  "fair
value"  based  method of  accounting  for stock-based  compensation  plans which
requires an  estimate  of  the fair  value  of  stock options  or  other  equity
instruments to which employees become entitled when they have rendered requisite
service    or    satisfied   other    conditions    necessary   to    earn   the
 
                                       58
<PAGE>
right to  benefit from  the instruments.  Compensation cost  is then  determined
based  on the  fair value  estimate and is  recognized over  the service period,
which is  usually  the vesting  period.  Statement  123 also  requires  that  an
employer's  financial statements  include certain  disclosures about stock-based
employee compensation arrangements regardless of the method used to account  for
them.
 
    The  accounting requirements of Statement 123 are effective for transactions
entered into in fiscal years that begin after December 15, 1995. In management's
opinion, implementation of Statement 123 has  not had and is not anticipated  to
have a material effect on the Company's consolidated financial statements.
 
QUARTER RESULTS
 
    Net  income for the  three months ended  March 31, 1996  was $2.6 million or
$0.41 per  share, reflecting  a net  increase of  $567,000 or  $0.09 per  share,
compared  to net income of $2.0 million or  $0.32 per share for the three months

ended  December 31, 1995. Earnings performance  for the three months ended March
31, 1996 compared to the  three months ended March  31, 1995 reflected gains  in
net  interest income and an increase  in noninterest income, partially offset by
an increase in noninterest  expense. Earnings performance  for the three  months
ended  March  31, 1996  compared to  the  three months  ended December  31, 1995
reflected gains in  net interest income  and an increase  in noninterest  income
reduced by an increase in noninterest expense.
 
    The  fourth quarter net income  for 1995 of $2.4  million or $0.39 per share
reflected an increase of $139,000 or 6.1% compared to $2.3 million or $0.37  per
share  for  the fourth  quarter  of 1994.  Earnings  performance for  the fourth
quarter of 1995 as compared to the fourth quarter of 1994 reflects increases  in
net  interest income, noninterest income  and noninterest expense. The following

</TABLE>
 
    Taxable-equivalent net interest income was $7.9 million for the three months
ended March 31, 1996, reflected an increase of $1.4 million or 21.7% compared to
taxable-equivalent net interest income for the three months ended March 31, 1995
of $6.5 million. The interest  rate margin of 5.38%  for the three months  ended
March  31, 1996 reflects a decrease of 16 basis points compared to 5.54% for the
three months ended March 31, 1995. The  increase in net interest income for  the
three  months ended March 31, 1996 compared  to the three months ended March 31,
1995  was   primarily  attributable   to   the  increase   in  the   volume   of
interest-earning  assets exceeding  the increase  in volume  of interest-bearing
liabilities and the change in  the mix of earnings  assets. The increase in  net
interest  income for  the three  months ended March  31, 1996  compared to three
months  ended   December   31,   1995  was   primarily   attributable   to   the
 
                                       59
<PAGE>
change  in the mix of interest-earning assets.  The average loan balance for the
three months ended March 31, 1996  of $457.4 million increased $44.6 million  or
10.8%  compared to the average loan balance  for the three months ended December
31, 1995. The  increase in  the average  balance of  loans outstanding  improved
earnings.  Total Interest-Earning  Assets for the  three months  ended March 31,
1996 of $590.5 million increased $16.4  million or 2.9% compared to the  average
Total Interest-Earning Assets for the three months ended December 31, 1995.
 
    Net interest income of $7.6 million for the fourth quarter of 1995 increased
$1.3  million or 21.4% compared to $6.3  million for the fourth quarter of 1994,
reflecting the increased volume of earning assets and net increase in yield  for
the  year ended December 31, 1995. Average  earning assets of $574.0 million for
the fourth quarter of 1995 increased $104.4 million or 22.2% compared to  $469.6
million  for the  fourth quarter  of 1994. The  fourth quarter  of 1995 interest
margin was 5.28% compared to 5.31% for  the fourth quarter of 1994 and 5.15%  in
the third quarter of 1995.
 
    The  provision for loan losses for the  three months ended March 31, 1996 of
$461,000 reflects an increase of $95,000  or 26.0% compared to $366,000 for  the
three months ended March 31, 1995 and was primarily attributable to loan growth.
 
    The provision for loan losses charged against earnings in the fourth quarter
of  1995  was $625,000  compared to  $455,000  for the  fourth quarter  of 1994,
reflecting an increase of  $170,000 or 37.4%. The  provision for loan losses  in
the fourth quarter of 1995 was primarily attributable to loan growth.
 
    Noninterest income for the three months ended March 31, 1996 of $1.9 million
increased  $356,000 or 22.4% compared to $1.6 million for the three months ended
March 31, 1995 and increased $217,000 or 12.6% compared to $1.7 million for  the
three months ended December 31, 1995. The increase in Noninterest income for the
three  months ended March 31, 1996 compared  to the three months ended March 31,
1995 is primarily attributable  to the increased fee  income from Total  Service
Charges,  Trust Service Fees  and Data Processing Service  Fees. The increase in
Total Service  Charges  was impacted  by  an  increase in  activity  levels  and
additional volume. The increase in Trust Service Fees for the three months ended
March  31, 1996 compared to three months ended March 31, 1995 is attributable to
increases in both  the number of  trust accounts  and the book  value of  assets
managed.  The book value of assets managed at March 31, 1996 and 1995 was $257.2
million and $205.0 million, respectively. Assets held by the trust department of
the Bank in fiduciary or agency capacities are not assets of the Company and are
not included in the consolidated balance sheets. The increase in Data Processing
Service Fees for the three months ended March 31, 1996 compared to three  months
ended March 31, 1995 is attributable to an increased volume of business.
 
    Noninterest  income of $1.7 million for the fourth quarter of 1995 increased
$215,000 or  14.2% compared  to $1.5  million for  the fourth  quarter of  1994,
primarily due to an increased volume of business and as a result of the RGC/Roma
Branch  Acquisitions. All components of noninterest income reflect increases for
fourth quarter of 1995 compared to  fourth quarter of 1994 except Other  Service
Charges  and Investment Securities Gains (Losses).  The decline in Other Service
Charges is  primarily attributable  to a  decline in  foreign currency  exchange
fees.  Investment Securities Gains (Losses) of  ($98,000) for the fourth quarter
of 1995  compared to  Investment Securities  Gains (Losses)  of $8,000  for  the
fourth quarter of 1994.
 
    Noninterest  expense  for the  three  months ended  March  31, 1996  of $5.3
million increased $720,000 or 15.7% compared to the three months ended March 31,
1995 of $4.6 million and increased $279,000 or 5.5% compared to the three months
ended December 31, 1995 of $5.0 million. The increase for the three months ended
March 31, 1996 compared to the three  months ended March 31, 1995 and the  three
months  ended  December 31,  1995 was  primarily  attributable to  the increased
volume of business conducted by the  Company. Personnel expense of $2.7  million
for  the three months ended March 31,  1996 increased $479,000 or 21.2% compared
to the three months ended  March 31, 1995 and $178,000  or 7.0% compared to  the
three  months ended December 31, 1995. Personnel expense increased for the three
months ended March 31, 1996  compared to the three  months ended March 31,  1995
primarily due to staffing increases, including the staff acquired as a result of
the RGC/Roma Branch Acquisitions, staff
 
                                       60

for  the New  Weslaco Banking Location  and increases in  payroll taxes, medical
insurance premiums and pension expenses for all employees. The Personnel expense
increase for the three months ended March 31, 1996 compared to the three  months
ended  December 31,  1995, was  primarily due  to staffing  increases, including
staffing increases associated with the  Company's New Weslaco Banking  Location.
The  New Weslaco Banking Location opened in February 1996. Net Occupancy expense
of $317,000 for the three months ended March 31, 1996 increased $64,000 or 25.3%
compared to $253,000 for the  three months ended March  31, 1995 and $38,000  or
13.6% compared to $279,000 for the three months ended December 31, 1995. The Net
Occupancy expense increase for the three months ended March 31, 1996 compared to
the three months ended March 31, 1995 is primarily due to the occupancy expenses
associated with the RGC/Roma Branch Acquisitions. Equipment expenses of $643,000
for  the three months ended March 31,  1996 increased $212,000 or 49.2% compared
to $431,000 for  the three  months ended  March 31,  1995 and  $79,000 or  14.0%
compared  to the  three months  ended December  31, 1995.  The Equipment expense
increase for the three months ended March 31, 1996 compared to the three  months
ended  March 31, 1995 is primarily due  to expenses associated with the RGC/Roma
Branch Acquisitions and the New Weslaco Banking Location.
 
    Noninterest expense of $5.0 million for the fourth quarter of 1995 increased
$1.2 million or 33.0% compared to $3.8  million for the fourth quarter of  1994.
The increase in noninterest expense is primarily attributable to Other Losses of
$239,000  for the fourth quarter  of 1995 reflecting a  net increase of $738,000
compared to a net gain of $499,000 for the fourth quarter of 1994. The net  gain
for  the  fourth quarter  of 1994  was  primarily attributable  to a  benefit of
$553,000 from the reversal of a second quarter 1994 accrual. The reversal of the
accrual resulted from the settlement of a lawsuit in the last quarter of 1994.

                                    BUSINESS
 
GENERAL
 
    Texas  Regional, a Texas  business corporation registered  as a bank holding
company under the Bank  Holding Company Act of  1956, was incorporated in  1983.
Texas  Regional  commenced  operations  as  a  bank  holding  company  with  the
acquisition of  Texas State  Bank,  McAllen, Texas,  and Harlingen  State  Bank,
Harlingen,  Texas  ("Harlingen State  Bank")  in May  1984.  In March  1992, the
Company acquired Mid Valley Bank, Weslaco, Texas ("Mid Valley Bank") and  merged
Harlingen  State Bank and Mid Valley Bank  into Texas State Bank. In 1995, Texas
State Bank acquired the Rio Grande City and Roma branches of First National Bank
of South Texas (the "RGC/Roma Branch Acquisitions"). Texas State Bank, which  is
the Company's sole subsidiary, operates nine banking locations in the Rio Grande
Valley:  four  banking locations  in McAllen  (including  its main  office), two
banking locations in Weslaco,  and one banking location  each in Harlingen,  Rio
Grande  City and Roma. At March 31,  1996, Texas Regional had consolidated total
assets of $655.9 million, loans outstanding (net of unearned discount) of $467.1
million, total deposits  of $586.0  million, and shareholders'  equity of  $64.6
million.  At December 31, 1995, Texas  Regional had consolidated total assets of
$646.8 million, loans outstanding (net of unearned discount) of $450.9  million,
total deposits of $579.7 million, and shareholders' equity of $62.7 million.
 
    Upon consummation of the Mergers, Texas State Bank will have 15 full service
banking  locations. In addition to the banking locations listed in the preceding
paragraph, Texas State Bank will add  one banking location in McAllen, three  in
Mission  and one  each in  Penitas and  Hidalgo. Assuming  the Mergers  and this
offering had been consummated  at March 31,  1996, the Bank  would have had  pro
forma  consolidated assets of $1.172 billion, loans outstanding (net of unearned
discounts) of  $709.6  million, total  deposits  of $1.049  billion,  and  total
shareholders'  equity of $109.8 million. Assuming  the Mergers and this offering
had been consummated at  December 31, 1995,  the Bank would  have had pro  forma
consolidated  assets  of  $1.144  billion, loans  outstanding  (net  of unearned
discounts) of  $685.3  million, total  deposits  of $1.024  billion,  and  total
shareholders' equity of $107.9 million.
 
    The  business strategy  of Texas  Regional is  for the  Bank to  provide its
customers with  the  financial  sophistication  and breadth  of  products  of  a
regional  bank,  while retaining  the local  appeal  and level  of service  of a
community bank. The Board of Directors and senior management of the Company have
maintained  the  Company's  community  orientation  by  tailoring  products  and
services  to meet  community and  customer needs.  Management believes  that the
Company is well positioned in its market due to its responsive customer service,
the strong community involvement of  Texas State Bank management and  employees,
recent trends in the Texas banking environment in general and the economy of the
Rio  Grande Valley in particular. Management's strategy is to provide a business
culture in which individual customers and small and medium sized businesses  are
accorded  the  highest  priority in  all  aspects of  the  Company's operations.
Management believes that individualized customer service will allow the  Company
to  increase its  market share in  lending volume  and deposits. As  part of its
operating and growth strategies, the Company  is working to continue to  attract
business  from, and provide  service to, small and  medium sized businesses, and
expand operations in the Rio Grande Valley. Management believes that the Mergers
are consistent with this strategy.
 
    By  maximizing  personal  knowledge  of  and  contact  with  customers   and
endeavoring  to  understand  the needs  and  preferences of  its  customers, the
Company is working to maintain and  further enhance its reputation of  providing
excellent  customer  service, allowing  it to  achieve  its growth  and earnings
goals. The Company has developed an  organizational structure that allows it  to
make  credit and other banking decisions  rapidly. Management believes that this
structure, when  compared  to  competing  financial  institutions,  enables  the
Company  to  provide a  higher degree  of service  and increased  flexibility to
creditworthy customers.
 
    The Bank  continues  to focus  on  small  and medium  sized  businesses  and
individual  customers as its principal market,  and seeks to provide services to
its customers across all product lines.  Many financial institutions in the  Rio
Grande   Valley  have  become  part  of   much  larger  state-wide  or  national
organizations. Management believes that the acquiring institutions in many cases
have shifted decision making
 
                                       62
<PAGE>
and operations out of  the Rio Grande Valley,  and therefore have decreased  the
level  of personal service that the Company seeks to provide to small and medium
sized businesses  that are  the  core of  the  Company's existing  business  and
marketing  efforts.  The Company  intends to  continue  to target  its marketing
efforts to those businesses and individuals who prefer the personalized customer
service emphasized by the Company.
 
    Bank management and other employees  participate actively in a wide  variety
of civic and community activities and organizations, including local chambers of
commerce,  industrial foundations  and charitable  and civic  activities such as
educational institutions, health care  organizations and the McAllen  Affordable
Housing Corporation. Management has also been actively involved in organizations
to  promote border  trade and  economic development.  The Company  believes that
these activities  assist  the  Bank through  increased  visibility  and  through
development and maintenance of customer relationships.
 
    For  its business  customers, Texas  State Bank  offers checking facilities,
certificates  of  deposit,  short  term  loans  for  working  capital  purposes,
construction financing, mortgage loans, term loans for fixed asset and expansion
needs,  and other  commercial loans.  The services  provided for  individuals by
Texas State Bank  include checking accounts,  savings accounts, certificates  of
deposit,  individual retirement  accounts and consumer  loan programs, including
installment loans for home repair and for purchases of consumer goods, including
automobiles, trucks  and  boats,  and  mortgage loans.  Texas  State  Bank  also
provides  travelers checks, money orders and safe deposit facilities, and offers
trust services. While First State Bank and Border Bank provide similar  services
and  products for  their customers, the  products and services  offered at these
locations will be expanded to include all products and services offered by Texas
State Bank.
 
    Texas State Bank has also expanded  the services which it provides to  third
party  correspondent banks.  The Texas  State Bank  data processing  center, for
example, presently serves three banks  in addition to providing data  processing
services  for  all Texas  State  Bank banking  locations.  It is  expected that,
following consummation  of the  Mergers  and a  conversion  in fall  1996,  data
processing  for the  bank facilities formerly  operated as First  State Bank and
Border Bank facilities will be performed by the Texas State Bank data processing
facility.
 
    The Company has  expanded its  market area  and increased  its market  share
through  both  internal growth  and through  acquisitions.  In August  1995, the
Company completed the RGC/Roma Branch  Acquisitions. In that transaction,  which
was  accounted for as a purchase, Texas State Bank acquired substantially all of
the fixed assets  associated with the  Rio Grande City  and Roma, Texas  banking
locations  acquired, certain loans  coded to the  banking locations, and certain
other assets, in  consideration of  the assumption of  certain deposit  accounts
coded to the banking locations. The RGC/Roma Branch Acquisitions increased loans
and deposits of the Company by $43.7 million and $79.7 million, respectively, at
the  time of  the acquisition.  In addition  to the  pending Mergers, management
believes there may be additional opportunities to expand by acquiring  financial
institutions  or by acquiring assets and deposits that will allow the Company to
enter adjacent markets  or further  increase market share  in existing  markets.
Management  intends to pursue acquisition  opportunities in strategic markets in
circumstances in which management believes that its managerial, operational  and
capital  resources will enhance the performance of acquired institutions. Except
for the Merger Agreements, there  are currently no agreements or  understandings
related to any acquisition.
 
MARKET REGIONS
 
    Texas  Regional's operations  are located  in the  Rio Grande  Valley, which
consists of Cameron, Hidalgo, Willacy  and Starr Counties. Cameron, Hidalgo  and
Starr  Counties are each directly adjacent to  the Rio Grande River, which forms
part of the  border between  the United States  and Mexico.  Texas State  Bank's
banking  locations are located in Hidalgo  County (McAllen and Weslaco), Cameron
County (Harlingen), and Starr County (Rio Grande City and Roma). The offices  of
First State Bank and Border Bank are all located in Hidalgo County.

    The   ability  of  Texas  Regional  to  continue  its  rate  of  growth  and
profitability is closely  linked to the  economy of the  Rio Grande Valley.  The
economy  of the Rio  Grande Valley is based  principally on retailing (including
trade with Mexico), government, agriculture, tourism, manufacturing, health care
and education. A large number of retirees spend  all or part of the year in  the
Rio  Grande  Valley.  Many  twin manufacturing  plants,  or  "maquiladoras", are
located in the  Rio Grande  Valley or  in cities  located across  the border  in
Mexico, such as Reynosa and Matamoros.
 
    The  City of McAllen,  which is the location  of the Company's headquarters,
serves as the  center of a  150 mile retail  market area. A  large part of  this
trade area is composed of the Mexican states of Nuevo Leon and Tamaulipas, which
had estimated populations of 3.1 million and 2.2 million, respectively, in 1990.
The  major  industrial and  commercial center  of northern  Mexico, the  City of
Monterrey in the Mexican state of Nuevo Leon, is located approximately 150 miles
southwest of  McAllen.  Among  the  largest  cities  in  the  Mexican  state  of
Tamaulipas are Reynosa, located ten miles south of McAllen and estimated to have
a population in excess of 700,000 persons, and Ciudad Victoria, which is located
200  miles  south of  McAllen.  The Rio  Grande  Valley market  includes  a U.S.
population of approximately  800,000, a  population which  increased 128.0%  (or
3.5% annually) between 1970 and 1994. The market area served by Texas State Bank
has  been  recognized as  among the  fastest  growing areas  in the  nation. The
McAllen-Edinburg-Mission area has  a projected population  growth rate of  23.8%
between  1994  and  2000, and  the  Brownsville-Harlingen area  has  a projected
population growth rate of 16.0% during that same period.
 
    The Rio Grande Valley has also experienced significant recent growth in  the
retail  and  construction  industries. Retail  sales  in the  Rio  Grande Valley
totaled approximately  $5.9 billion  in 1994,  representing an  annual  compound
growth  rate  of 7.9%  since 1984.  With respect  to new  construction activity,
building permits in  the Rio  Grande Valley have  grown 89.8%  between 1989  and
1994, representing an annual compound growth rate of 13.7%.
 
LENDING ACTIVITIES
 
    The  primary source of income generated by  Texas State Bank is the interest
earned from  its loan  and  investment portfolios.  Texas State  Bank  maintains
diversification  when considering investments and the granting of loan requests.
Emphasis is placed on  the borrower's ability to  generate cash flow to  support
its debt obligations and other cash related expenses. Lending activities include
commercial  loans,  agricultural loans,  consumer loans  and real  estate loans.
Commercial loans and  agricultural loans  are originated  primarily for  working
capital  funding. Consumer loans include those  for the purchase of automobiles,
mobile homes, home improvements and  investments. Real estate loans include  the
origination of loans for commercial property acquisition or remodeling, and also
include conventional mortgages for the purchase of single-family houses or lots.
A  substantial proportion of  the properties collateralizing  Texas State Bank's
mortgage portfolio is located in the Company's primary market area.
 
    During 1995,  Frank A.  Kavanagh, President  of Texas  State Bank's  Weslaco
banking  location, was appointed the Chief  Lending Officer of Texas State Bank.
During  1995,  Texas   State  Bank  also   further  standardized   documentation
requirements  and centralized  loan controls  and supervision.  Texas State Bank
management continues to seek to preserve  and enhance the quality of the  Bank's
loan portfolio.
 
    At  March 31, 1996,  Texas Regional's total loan  portfolio (net of unearned
discount) was $467.1 million representing 79.7% and 71.2% of its total  deposits
and  total  assets, respectively,  at that  date.  Total loans  increased $112.6
million, or 31.8%, during the twelve month period from March 31, 1995 levels  of
$354.4 million. At December 31, 1995, Texas Regional's total loan portfolio (net
of  unearned discount) was  $450.9 million, representing 77.8%  and 69.7% of its
total deposits  and  total  assets,  respectively, at  that  date.  Total  loans
increased $110.9 million, or 32.6%, during 1995 from December 31, 1994 levels of
$339.9  million.  In  each case,  a  significant  portion of  this  increase was
attributable to the  RGC/Roma Branch Acquisitions.  The Company's legal  lending
limit  to any one borrower was $11.5  million at December 31, 1995. However, the
legal lending limit  does not include  the portion of  a loan collateralized  by
cash  or cash equivalents and government guaranties. All current loans fall well
below applicable legal lending limits. Texas Regional's lending policy generally
limits loans to one borrower to $8.0 million,
 
                                       64
<PAGE>
with exceptions allowed for selected customers. An example of an exception is  a
$34.0 million loan made during 1995 to fund a leveraged employee stock ownership
trust,  which was secured by,  among other assets, cash  and cash equivalents of
$27.5 million. See "Texas Regional Bancshares, Inc. Management's Discussion  and
Analysis of Financial Condition and Results of Operations--Analysis of Financial
Condition--Loans."
 
    Assuming  consummation of  the Mergers,  on a pro  forma basis  at March 31,
1996, Texas Regional's  total loan  portfolio (net of  unearned discount)  would
have  been $709.6  million and  its legal  lending limit  would have  been $21.5
million. Assuming consummation of the Mergers, on a pro forma basis at  December
31, 1995, Texas Regional's total loan portfolio (net of unearned discount) would
have  been $685.3  million and  its legal  lending limit  would have  been $21.5
million.
 
    At March 31, 1996,  First State Bank  and Border Bank  had $16.4 million  of
loans  secured by non-U.S. collateral, primarily real estate and other assets in
Mexico. At December 31, 1995, First State Bank and Border Bank had $13.0 million
of loans secured by non-U.S. collateral, primarily real estate and other  assets
in  Mexico.  Management  of Texas  Regional  currently intends  to  maintain the
portfolio of such loans but does  not intend to significantly expand the  volume
of such loans.
 
    The  following table  summarizes the loan  portfolio of the  Company by loan
category and amount  at March 31,  1996 and on  a pro forma  basis at March  31,
1996, assuming that the Mergers had been consummated at March 31, 1996:

COMMERCIAL LENDING
 
    Commercial loans at March 31, 1996 of $151.2 million increased $44.6 million
or  41.8% compared to March 31, 1995  level of $106.7 million and increased $4.8
million or  3.2% compared  to December  31, 1995  level of  $146.5 million.  The
increase  in commercial loans at March 31,  1996 compared to commercial loans at
March 31, 1995 is  primarily attributable to  the RGC/Roma Branch  Acquisitions,
funding  a  $34.0  million leveraged  employee  stock ownership  trust  loan and
management's efforts to improve the earnings mix of earning assets by increasing
loan volume. At December 31, 1995, the Company had $146.5 million of  commercial
loans  outstanding,  representing  32.5%  of its  total  loans.  Commercial loan
balances increased $44.6 million, or 43.8%,  during 1995 from December 31,  1994
level  of $101.9 million.  The increase in  commercial loans for  the year ended
December 31, 1995 was primarily attributable  to the funding of a $34.0  million
leveraged  employee stock ownership trust loan  which is collateralized by stock
and assets of  the employer  and approximately $27.5  million of  cash and  cash
equivalent  assets. Excluding this  loan, commercial loans  at December 31, 1995
represented an  increase  of $10.6  million,  or  10.4%, compared  to  level  at
December  31, 1994. On  a pro forma basis  at March 31,  1996, the Company would
have had $228.5 million of  commercial loans outstanding, representing 32.2%  of
total  loans at March 31, 1996.  On a pro forma basis  at December 31, 1995, the
Company  would  have  had  $215.3  million  of  commercial  loans   outstanding,
representing 31.4% of total loans at December 31, 1995.
 
    Texas State Bank offers a variety of commercial loan services including term
loans,   lines  of   credit,  and   equipment  financing.   A  broad   range  of
short-to-medium term commercial loans, both collateralized and uncollateralized,
is made available  to businesses  for working capital  (including inventory  and
receivables),  business  expansion (including  acquisitions  of real  estate and
improvements), and the  purchase of equipment  and machinery. The  purpose of  a
particular loan generally determines its structure.
 
    Generally,  Texas  State Bank's  commercial  loans are  underwritten  in the
Bank's primary market  area on the  basis of the  borrower's ability to  service
such  debt  from  income. As  a  general  practice, Texas  State  Bank  takes as
collateral a lien  on any  available real  estate, equipment,  or other  assets.
Working  capital loans are primarily collateralized by short-term assets whereas
term loans are primarily collateralized by long-term assets.
 
    Unlike residential mortgage loans, which generally are made on the basis  of
the  borrower's ability to  make repayment from his  employment and other income
and which  are collateralized  by real  property whose  value tends  to be  more
readily  ascertainable, commercial loans typically are underwritten on the basis
of the borrower's ability to make repayment  from the cash flow of its  business
and   generally  are  collateralized  by   business  assets,  such  as  accounts
receivable, equipment and inventory. As a  result, the availability of funds  or
collateral  value available  to support  the repayment  of commercial  loans may
deteriorate over time,  cannot be  appraised with precision,  and may  fluctuate
based on the success of the business.
 
AGRICULTURAL LOANS
 
    At  March  31, 1996,  the Company  had $28.4  million of  agricultural loans
outstanding, representing 6.1%  of its total  loans. Agricultural loan  balances
increased  $8.5 million, or 42.4%, during the twelve month period from March 31,
1995 level of $20.0 million. On a pro forma basis at March 31, 1996, the Company
would have had  $38.2 million  of agricultural  loans outstanding,  representing
5.4%  of total  loans. At December  31, 1995,  the Company had  $25.1 million of
agricultural  loans  outstanding,   representing  5.6%  of   its  total   loans.
Agricultural  loan balances increased  $7.9 million, or  45.9%, during 1995 from
December 31, 1994 level of $17.2 million.  On a pro forma basis at December  31,
1995,   the  Company  would  have  had   $34.0  million  of  agricultural  loans
outstanding, representing 5.0% of total loans.
 
REAL ESTATE LOANS
 
    At March  31, 1996,  the Company  had $244.2  million of  real estate  loans
outstanding.  Real estate loan balances increased $48.6 million, or 24.8% during
the twelve month period from March 31, 1995 level of $195.6 million. Real estate
loans represented 52.3% and 55.2% of  total loans outstanding at March 31,  1996
and  1995, respectively.  On a pro  forma basis  at March 31,  1996, the Company
would have had
 
                                       66
<PAGE>
$379.0 million of  real estate loans  outstanding, or 53.4%  of total loans.  At
December  31,  1995,  the  Company  had  $236.0  million  of  real  estate loans
outstanding. Real estate loan balances increased $45.9 million, or 24.1%  during
1995  from  December  31,  1994  level  of  $190.2  million.  Real  estate loans
represented 52.3% and 55.9% of total loans outstanding at December 31, 1995  and
1994, respectively. On a pro forma basis at December 31, 1995, the Company would
have  had $371.3  million of  real estate loans  outstanding, or  54.2% of total
loans.
 
    A substantial portion of the Bank's  real estate mortgage loans are  secured
by non-farm, non-residential properties, which are loans to commercial customers
for  purposes of providing working capital. In addition, some of the Bank's real
estate mortgage loans have been made to finance or refinance the acquisition and
holding of commercial real  estate. The Bank offers  a variety of mortgage  loan
products  which generally are (i) amortized over  five to 15 years, (ii) payable
in monthly installments of principal and interest, and (iii) due and payable  in
full within three to five years.
 
    Finally, a small portion of the Bank's lending activity has consisted of the
origination  of  single-family  residential  mortgage  loans  collateralized  by
owner-occupied property  located in  the Bank's  primary market  area. The  Bank
intends  to pursue increased originations  of single-family residential mortgage
loans with respect to its existing customer base. Loans collateralized by single
family residential real estate generally have  been originated in amounts of  no
more than 85% of appraised value. The Bank requires mortgage title insurance and
hazard  insurance  in the  amount  of the  loan.  Although the  contractual loan
payment periods for single  family residential real  estate loans are  generally
amortized  over five to  20 years, they  are payable in  monthly installments of
principal and interest and are typically due and payable in full within three to
five years. At March 31, 1996 and December 31, 1995, approximately $13.0 million
of the single family residential mortgage  loans at First State Bank and  Border
Bank   consisted  of   loans  to   low  and   moderate  income   borrowers.  The
characteristics  of  these   loans  may   contribute  to  a   higher  level   of
delinquencies.  Management  believes  that  this  component  of  the  pro  forma
portfolio will not have  an adverse impact on  the financial performance of  the
Company.
 
CONSUMER LOANS
 
    At  March  31,  1996,  the  Company  had  $43.2  million  of  consumer loans
outstanding, representing  9.2%  of its  total  loans. Aggregate  consumer  loan
balances  increased $11.0 million, or 34.3%, during the twelve month period from
March 31, 1995 level of $32.1 million. On  a pro forma basis at March 31,  1996,
the  Company would have had $63.8 million of consumer loans outstanding, or 9.0%
of its total  loans. At  December 31,  1995, the  Company had  $43.3 million  of
consumer  loans  outstanding, representing  9.6% of  its total  loans. Aggregate
consumer loan  balances increased  $12.6  million, or  40.9%, during  1995  from
December  31, 1994 level of $30.7 million. On  a pro forma basis at December 31,
1995, the Company would have had $64.7 million of consumer loans outstanding, or
9.4% of its total loans.
 
    Consumer loans made by the Bank have included automobile loans, recreational
vehicle loans,  boat  loans,  second mortgage  loans,  home  improvement  loans,
personal   loans  (collateralized  and  uncollateralized)  and  deposit  account
collateralized loans. The  terms of these  loans typically range  from 12 to  60
months and vary based upon the nature of collateral and size of loan.
 
    Consumer  loans are  attractive to  the Bank  because they  typically have a
short term and carry higher interest rates than those charged on other types  of
loans.  Installment loans, however,  do pose additional  risks of collectability
when compared to traditional types of loans granted by commercial banks, such as
residential mortgage loans. In many instances,  the Bank is required to rely  on
the  borrower's ability to repay since the collateral may be of reduced value at
the time of collection. Accordingly, the initial determination of the borrower's
ability to repay is of primary importance in the underwriting of consumer loans.
 
INVESTMENTS
 
    At March 31, 1996 the  Company had federal funds  sold of $13.2 million  and
investment  securities of $113.4 million,  including $57.5 million classified as
Available for Sale and $55.9 million classified as Held to Maturity. At December
31, 1995  the Company  had federal  funds sold  of $3.6  million and  investment
 
                                       67
<PAGE>
securities  of $131.6 million,  including $63.1 million  classified as Available
for Sale  and $68.5  million classified  as Held  to Maturity.  Investments  are
managed  to maintain  adequate sources of  liquidity and  diversification and to
generate acceptable levels of tax-equivalent yield.
 
    On a pro forma basis at March  31, 1996, after giving effect to the  Mergers
and  this offering at March  31, 1996, the Company  would have had federal funds
sold of $24.8  million and  investment securities of  $310.7 million,  including
$83.7  million classified as Available for Sale and $227.0 million classified as
Held to Maturity. On a pro forma basis at December 31, 1995, after giving effect
to the Mergers and this  offering at December 31,  1995, the Company would  have
had  federal  funds sold  of $4.9  million and  investment securities  of $328.1
million, including $65.9  million classified  as Available for  Sale and  $262.2
million  classified  as  Held to  Maturity.  The pro  forma  adjustments include
assumptions regarding the use  of sources of  liquidity including federal  funds
sold  and  sales of  certain  investment securities  to  fund a  portion  of the
purchase  price.  See  "Texas  Regional  Bancshares,  Inc.  Pro  Forma  Combined
Condensed  Financial Information." Management believes that sources of liquidity
will be adequate to  fund the required portion  of consideration in the  Mergers
but will decide on specific securities to be sold, if necessary, based on market
conditions at the time of Closing.

DEPOSITS
 
    The Company has a stable noninterest-bearing source of funds as reflected in
the ratio of  average demand deposits  to average total  deposits for the  three
months  ended March 31, 1996 and 1995  of 20.5% and 20.5%, respectively, and for
the years ended  December 31, 1995  and 1994 of  20.2% and 20.9%,  respectively.
Deposits  provide funding for the Company's investments in loans and securities,
and the interest  paid for  deposits must be  managed carefully  to control  the
level of interest expense.
 
    Texas  State  Bank's  deposits  at  March  31,  1996  were  $586.0  million,
reflecting an  increase of  $110.0 million,  or 23.1%  during the  twelve  month
period  from March 31, 1995 level of $476.0 million. Texas State Bank's deposits
at December 31,  1995 were  $579.7 million, an  increase of  $107.6 million,  or
22.8%  during 1995 from December 31, 1994  level of $472.1 million. A portion of
this increase was  attributable to  the RGC/Roma  Branch Acquisitions.  Deposits
currently  consist primarily  of core  deposits from  the Rio  Grande Valley and
surrounding areas.  Texas State  Bank  does not  have any  "brokered  deposits",
defined  as deposits  which, to the  knowledge of management  of Texas Regional,
have been placed with the Bank by a person who acts as a broker in placing  such
deposits on behalf of others. On a pro forma basis at March 31, 1996, the Bank's
deposits  would have been $1.049  billion, and on a  pro forma basis at December
31, 1995, the Bank's deposits would have been $1.024 billion.
 
    At March  31, 1996,  certificates of  deposit held  by Texas  State Bank  in
excess  of $100,000 were  $132.9 million, or  22.7% of total  deposits. On a pro
forma basis at  March 31,  1996, certificates  of deposit  held by  the Bank  in
excess of $100,000 would have been $293.7 million, or 28.0% of total deposits.
 
    Texas State Bank acts as local depository for a number of local governmental
entities  in its  market area,  including the City  of McAllen,  the South Texas
Community College District, the City of Weslaco, the Weslaco Independent  School
District,  the City of Rio Grande City, the City of Roma and Starr County. Local
government deposits are  subject to competitive  bid and in  many cases must  be
secured by government securities. Total deposits by or on behalf of governmental
entities  at March 31, 1996, aggregated  approximately $39.8 million, or 6.8% of
total deposits.  On a  pro  forma basis  at March  31,  1996, the  Bank's  total
deposits  by or on behalf of government entities would have been $149.2 million,
or 14.2% of total deposits.
 
    As with loan transactions, Texas State Bank has developed deposit  relations
with  depositors who are Mexican residents. At March 31, 1996, $56.6 million, or
9.7% of the Bank's total demand and time deposits were deposited primarily by or
on behalf of residents of Mexico. On a pro forma basis at March 31, 1996, $147.0
million, or 14.0% of the Bank's total demand and time deposits, would have  been
deposited  primarily  by or  on  behalf of  residents  of Mexico.  As  with loan
transactions, management believes that Texas State Bank's percentage of deposits
by or on behalf of residents of Mexico, and the percentage of deposits on a  pro
forma  basis at March 31,  1996, on behalf of  residents of Mexico, are somewhat
less than that of banks of comparable size located in the Rio Grande Valley.
 
COMPETITION
 
    The banking industry in the market area served by Texas State Bank is highly
competitive. Competition  among financial  institutions is  based upon  interest
rates  offered on  deposit accounts, interest  rates charged on  loans and other
credit and service charges, the quality and scope of the services rendered,  the
convenience  of  banking facilities,  and, in  the case  of loans  to commercial
borrowers, relative lending limits. A substantial number of the commercial banks
in the Rio Grande  Valley are branches of  much larger organizations  affiliated
with  national, regional  or state-wide  banking companies,  and as  a result of
those affiliations have  greater resources  than Texas Regional  or Texas  State
Bank.  However, as  an independent community  bank headquartered  in Texas State
Bank's primary market area, management of the Company believes that Texas  State
Bank's  community commitment and involvement in its primary market area, as well
as its commitment to quality and personalized banking services, are factors that
contribute to the Company's competitiveness.

PERSONNEL
 
    At  March  31,  1996,  Texas  Regional  employed  351  full-time  equivalent
employees,  and on a pro forma basis at  March 31, 1996, would have employed 494
full-time equivalent employees.  Substantially all  of the  present First  State
Bank and Border Bank officers and employees are expected to be employed by Texas
State  Bank. The Company's employees are  not unionized, and management believes
employee relations to be favorable.
 
PROPERTIES
 
    Texas State Bank targets commercial customers  by offering a broad range  of
commercial  banking  services  through  a total  of  nine  full  service banking

REGULATION AND SUPERVISION
 
    In addition to  the generally  applicable state and  federal laws  governing
businesses  and  employers,  the  Company  and  Texas  State  Bank  are  further
extensively regulated  by special  federal  and state  laws applicable  only  to
financial  institutions and their parent companies. Virtually all aspects of the
Company's operations are  subject to specific  requirements or restrictions  and
general   regulatory   oversight,   from   laws   regulating   consumer  finance
transactions, such as the Truth In Lending Act, the Home Mortgage Disclosure Act
and the  Equal  Credit  Opportunity  Act, to  laws  regulating  collections  and
confidentiality,  such  as the  Fair Debt  Collections  Practices Act,  the Fair
Credit  Reporting  Act  and  the  Right  to  Financial  Privacy  Act.  With  few
exceptions,  state and  federal banking laws  have as  their principal objective
either the  maintenance of  the  safety and  soundness  of the  federal  deposit
insurance  system or the protection of consumers or classes of consumers, rather
than the specific protection of shareholders  of the Company. To the extent  the
following material describes statutory or regulatory provisions, it is qualified
in its entirety by reference to the particular statute or regulation.
 
    REGULATION OF THE COMPANY
 
    Texas  Regional is  a bank  holding company within  the meaning  of the Bank
Holding Company Act of  1956 ("BHCA"), as amended,  and therefore is subject  to
regulation  and supervision by the FRB. In  addition, the Company is required to
file reports with and to furnish such  other information as the FRB may  require
pursuant  to the BHCA, and to subject itself  to examination by the FRB. The FRB
has the authority  to issue bank  holding companies orders  to cease and  desist
from  unsound practices and violations of conditions imposed by, or violation of
agreements with, the FRB.  The FRB is also  empowered to assess civil  penalties
against  companies or individuals who violate  the BHCA or orders or regulations
thereunder in  amounts up  to $1.0  million  per day,  to order  termination  of
non-banking  activities of  non-banking subsidiaries of  bank holding companies,
and to order termination of ownership and control of a non-banking subsidiary by
a  bank  holding  company.  Certain  violations  may  also  result  in  criminal
penalties.  The FRB  and the  FDIC, as  appropriate, are  authorized to exercise
comparable authority, under the  Federal Deposit Insurance  Act (the "FDI  Act")
and other statutes, with respect to subsidiary banks.
 
    The  FRB takes the position that a bank holding company is required to serve
as a source of financial and managerial strength to its subsidiary banks and may
not conduct its operations in an unsafe or
 
                                       71
<PAGE>
unsound manner. In  addition, it is  the FRB's  position that, in  serving as  a
source  of strength to its subsidiary banks, a bank holding company should stand
ready to  use available  resources  to provide  adequate  capital funds  to  its
subsidiary  banks during  periods of  financial stress  or adversity  and should
maintain the  financial  flexibility  and  capital-raising  capacity  to  obtain
additional  resources  for  assisting  its  subsidiary  banks.  A  bank  holding
company's failure to meet its  obligations to serve as  a source of strength  to
its subsidiary banks will generally be considered by the FRB to be an unsafe and
unsound  banking practice or  a violation of  the FRB regulations  or both. This
doctrine has become  known as the  "source of strength"  doctrine. Although  the
United  States Court of Appeals for the  Fifth Circuit found the FRB's source of
strength doctrine invalid  in 1990,  stating that the  FRB had  no authority  to
assert  the doctrine  under the  BHCA, the decision  was reversed  by the United
States Supreme Court on procedural grounds. Changes  in the FDI Act made by  the
FDICIA  now  require an  undercapitalized  institution to  submit  to the  FRB a
capital restoration plan with a guaranty  by each company having control of  the
bank of the bank's compliance with the plan.
 
    The  BHCA  and the  Change in  Bank Control  Act, together  with regulations
promulgated by the FRB, require that, depending on the particular circumstances,
either FRB approval must be obtained or notice must be furnished to the FRB  and
not  disapproved prior to  any person or  company acquiring "control"  of a bank
holding company, such as the Company, subject to certain exemptions for  certain
transactions.  Control is  conclusively presumed  to exist  if an  individual or
company acquires 25%  or more  of any  class of  voting securities  of the  bank
holding  company. Control is  rebuttably presumed to exist  if a person acquires
10% or more but less than 25% of  any class of voting securities and either  the
company  has registered securities  under Section 12  of the Exchange  Act or no
other person will own  a greater percentage of  that class of voting  securities
immediately  after  the transaction.  The  regulations provide  a  procedure for
challenge of the rebuttable control presumption.
 
    As a bank holding company, the Company is required to obtain approval  prior
to  merging or consolidating with any  other bank holding company, acquiring all
or substantially all of the assets of any bank or acquiring ownership or control
of shares of  a bank  or bank  holding company  if, after  the acquisition,  the
Company  would directly or  indirectly own or  control 5% or  more of the voting
shares of such bank or bank holding company.
 
    The Company is also prohibited from acquiring a direct or indirect  interest
in or control of more than 5% of the voting shares of any company which is not a
bank  or  bank  holding company  and  from  engaging directly  or  indirectly in
activities other  than  those  of  banking, managing  or  controlling  banks  or
furnishing services to its subsidiary bank, except that it may engage in and may
own  shares of companies engaged in certain activities found by the FRB to be so
closely related to banking or managing and  controlling banks as to be a  proper
incident  thereto. These activities include, among others, operating a mortgage,
finance, credit card, or factoring  company; performing certain data  processing
operations;  providing investment and  financial advice; acting  as an insurance
agent for certain types of  credit-related insurance; leasing personal  property
on a full-payout, non-operating basis; and providing certain stock brokerage and
investment  advisory  services. In  approving  acquisitions or  the  addition of
activities,  the  FRB  considers  whether  the  acquisition  or  the  additional
activities can reasonably be expected to produce benefits to the public, such as
greater  convenience,  increased  competition,  or  gains  in  efficiency,  that
outweigh such  possible adverse  affects as  undue concentration  of  resources,
decreased  or  unfair  competition,  conflicts of  interest  or  unsound banking
practices. In  considering any  application for  approval of  an acquisition  or
merger,  the  FRB is  also  required to  consider  the financial  and managerial
resources of the companies and the  banks concerned, as well as the  applicant's
record  of compliance with  the Community Reinvestment Act  (the "CRA"). The CRA
generally requires  a  financial  institution  to  take  affirmative  action  to
ascertain  and meet the credit needs of  its entire community, including low and
moderate income neighborhoods.
 
    The BHCA generally imposes certain  limitations on extensions of credit  and
other  transactions by and between banks that are members of the Federal Reserve
System and other banks and non-bank
 
                                       72
<PAGE>
companies in the same holding company. Under the BHCA and the FRB's regulations,
a bank holding  company and  its subsidiaries  are prohibited  from engaging  in
certain tie-in arrangements in connection with any extension of credit, lease or
sale of property or furnishing of services.
 
    The Company, as an affiliate of the Bank, is subject to certain restrictions
regarding transactions between a bank and companies with which it is affiliated.
These  provisions limit extensions of credit  (including guarantees of loans) by
the Bank to  affiliates, investments  in the stock  or other  securities of  the
Company  by the Bank, and the nature and  amount of collateral that the Bank may
accept from any affiliate to secure loans extended to the affiliate.
 
    REGULATION OF THE BANK
 
    Texas State Bank is  a Texas state-chartered bank  subject to regulation  by
the  Banking Department. Texas State Bank, the  deposits of which are insured by
the Bank Insurance Fund (the "BIF") of the FDIC, is also a member of the Federal
Reserve System, and therefore the FRB is the primary federal regulator for Texas
State Bank.
 
    The requirements and restrictions applicable to Texas State Bank under  laws
of  the United States  and the State  of Texas include  (i) the requirement that
reserves be maintained,  (ii) restrictions  on the  nature and  amount of  loans
which  can be made, (iii)  restrictions on the business  activities in which the
Bank may engage, (iv) restrictions on the payment of dividends to  shareholders,
and (v) the maintenance of minimum capital requirements.
 
    Texas  Regional is dependent  upon dividends received  from Texas State Bank
for discharge of Texas  Regional's obligations and for  payment of dividends  to
the   Company's  shareholders.  However,  the  application  of  minimum  capital
requirements and  other rules  and regulations  applicable to  Texas State  Bank
restrict  dividend payments by Texas State  Bank. The Banking Department and the
FRB can each  further limit  payment of  dividends if  the regulatory  authority
finds  that  the payment  of  dividends would  constitute  an unsafe  or unsound
practice. In addition, Texas law requires that, before declaring a dividend, not
less than 10% of the  net profits of a bank  earned since the last dividend  was
declared  be  transferred to  a "certified  surplus"  account. Except  to absorb
losses in excess of  undivided profits and  uncertified surplus, such  certified
surplus  may not  be reduced  without the prior  written consent  of the Banking
Commissioner. However, state banks are not required to transfer any amount  that
would  increase the certified  surplus account to  more than the  capital of the
bank. See "Texas Regional Bancshares, Inc. Management's Discussion and  Analysis
of  Financial  Condition  and Results  of  Operations --  Liquidity  and Capital
Resources."
 
    Interest rate limitations for Texas State Bank are primarily governed by the
laws of the State of Texas. The maximum annual interest rate that may be charged
on most loans made by Texas State Bank is based on doubling the average  auction
rate, to the nearest 0.25%, for United States Treasury Bills, as computed by the
Office  of  Consumer Credit  Commissioner of  the State  of Texas.  However, the
maximum rate does not decline below 18%  or rise above 24% (except for loans  in
excess  of $250,000 that are made  for business, commercial, investment or other
similar purposes  (excluding  agricultural loans),  in  which case  the  maximum
annual  rate may not rise above 28%,  rather than 24%). On fixed rate closed-end
loans, the maximum non-usurious rate is to be determined at the time the rate is
contracted, while on floating  rate and open-end loans  (such as credit  cards),
the  rate varies over  the term of  the indebtedness. State  usury laws (but not
late charge limitations) have been preempted by federal law for loans secured by
a first lien on residential real property.
 
    Banks are affected  by the  credit policies of  other monetary  authorities,
including  the  FRB, which  regulate the  national supply  of bank  credit. Such
regulation influences overall  growth of bank  loans, investments, and  deposits
and  may also affect interest  rates charged on loans  and paid on deposits. The
monetary policies of  the FRB  have had a  significant effect  on the  operating
results of commercial banks in the past and are expected to continue to do so in
the future.

    FDICIA
 
    FDICIA  requires  that  federal  bank  regulatory  authorities  take "prompt
corrective action" with  respect to  any depository institution  which does  not
meet   specified  minimum  capital   requirements.  The  applicable  regulations
establish five  capital  levels  which  require or  permit  the  FRB  and  other
regulatory  authorities to take supervisory action. The relevant classifications
range from  "well capitalized"  to  "critically undercapitalized".  Under  these
regulations,  which  became  effective  December  19,  1992,  an  institution is
considered well capitalized if it has a total risk-based capital ratio of  10.0%
or greater, a Tier I risk-based capital ratio of 6.0% or greater, and a leverage
ratio  of 5.0% or greater, and it is not subject to an order, written agreement,
capital directive, or prompt corrective action directive to meet and maintain  a
specific  capital level  for any capital  measure. An  institution is considered
adequately capitalized if  it has a  total risk-based capital  ratio of 8.0%  or
greater,  a Tier I  risk-based capital ratio  of 4.0% or  greater and a leverage
capital ratio of 3.0% or greater (if the institution is rated composite 1 in its
most recent report of examination, subject to appropriate federal banking agency
guidelines), and  the  institution  does  not meet  the  definition  of  a  well
capitalized institution. An institution is considered undercapitalized if it has
a  total risk-based capital  ratio that is  less than 8.0%,  a Tier I risk-based
capital ratio that is less than 4.0%, or a leverage ratio that is less than 4.0%
(or a  leverage  ratio that  is  less than  3.0%  if the  institution  is  rated
composite  1 in  its most recent  report of examination,  subject to appropriate
federal banking agency guidelines). A significantly undercapitalized institution
is one which has a total risk-based capital ratio that is less than 6.0%, a Tier
I risk-based capital ratio that is less  than 3.0%, or a leverage ratio that  is
less  than 3.0%.  A critically undercapitalized  institution is one  which has a
ratio of tangible equity to total assets that is equal to or less than 2.0%.
 
    The FRB is authorized by the legislation to take various enforcement actions
against any significantly undercapitalized institution and any  undercapitalized
institution that fails to submit an acceptable capital restoration plan or fails
to  implement a plan  accepted by the appropriate  agency. These powers include,
among other things, requiring the  institution to be recapitalized,  prohibiting
asset  growth,  restricting interest  rates  paid, requiring  prior  approval of
capital  distributions  by   any  bank  holding   company  which  controls   the
institution,  requiring divestiture by the institution of its subsidiaries or by
the holding  company of  the institution  itself, requiring  a new  election  of
directors,  and  requiring  the  dismissal  of  directors  and  officers.  These
restrictions, either  individually or  in  aggregate, could  if imposed  have  a
significantly adverse impact on the operations of the Bank.
 
    With  certain  exceptions, an  institution  will be  prohibited  from making
capital  distributions  or  paying  management  fees  if  the  payment  of  such
distributions  or fees  will cause  the institution  to become undercapitalized.
Furthermore, undercapitalized  institutions will  be  required to  file  capital
restoration  plans with the  appropriate federal regulator.  Pursuant to FDICIA,
undercapitalized institutions also  will be subject  to restrictions on  growth,
acquisitions,  branching and engaging in new  lines of business unless they have
an approved capital plan that permits  otherwise. The FRB also may, among  other
things,  require an undercapitalized institution to issue shares or obligations,
which could be voting stock, to  recapitalize the institution or, under  certain
circumstances to divest itself of any subsidiary.
 
    Critically  undercapitalized institutions  may be subject  to more extensive
control and supervision and the FRB may prohibit any critically undercapitalized
institution from, among other things, entering into any material transaction not
in the ordinary course of business, amending its charter or bylaws, or  engaging
in    certain   transactions   with    affiliates.   In   addition,   critically
undercapitalized institutions generally will be prohibited from making  payments
of  principal or interest on outstanding subordinated debt. Within 90 days of an
institution  becoming  critically  undercapitalized,  the  FRB  must  appoint  a
receiver  or conservator  unless certain findings  are made with  respect to the
prospect for the institution's continued operation.

    Based  on Texas State Bank's  capital ratios at March  31, 1996 and December
31, 1995,  Texas State  Bank  was classified  as  "well capitalized"  under  the
applicable  regulations. On a pro forma basis at March 31, 1996 and December 31,
1995, Texas State Bank would also have been "well capitalized" under  applicable
regulations.  As a  result, the  Company does  not believe  that FDICIA's prompt
corrective action regulations will have any material effect on the activities or
operations of Texas State Bank.
 
    FDICIA also requires the  FDIC to establish a  schedule to increase (over  a
period  of not more than  15 years) the reserve ratio  of the BIF, which insures
deposits of Texas State  Bank, to 1.25% of  insured deposits, and impose  higher
deposit  insurance premiums on BIF members, if necessary, to achieve that ratio.
FDICIA also  requires  a  risk-based assessment  system  for  deposit  insurance
premiums  commencing January 1,  1994. Since BIF  reached its designated reserve
ratio in mid-1995, the FDIC adjusted the BIF assessments, so that the assessment
rate now in effect ranges from a minimum of zero to a maximum of $0.27 per  $100
of  deposits. Institutions whose  assessment rate would be  zero are required to
pay a  statutory minimum  semiannual assessment  of $1,000.  Based on  the  risk
category applicable to Texas State Bank, the premium paid by Texas State Bank is
presently $2,000 per annum.
 
    FDICIA  contains numerous  other provisions,  including accounting, auditing
and reporting requirements, the termination (beginning in 1995) of the "too  big
to fail" doctrine except in special cases, regulatory standards in areas such as
asset  quality, earnings and compensation,  and revised regulatory standards for
the powers of  state chartered  banks, real  estate lending,  bank closures  and
capital adequacy.
 
    COMMUNITY REINVESTMENT ACT
 
    Under  the CRA,  a bank's applicable  regulatory authority (the  FDIC or the
FRB) is required  to assess the  record of each  financial institution which  it
regulates  to determine if the institution meets  the credit needs of its entire
community, including  low-  and  moderate-income  neighborhoods  served  by  the
institution,  and to  take that  record into  account in  its evaluation  of any
application made by such  institution for, among other  things, approval of  the
acquisition  or establishment of  a branch or other  deposit facility, an office
relocation, a merger, or the acquisition  or shares of capital stock of  another
financial institution. The regulatory authority prepares a written evaluation of
an  institution's record of meeting the credit needs of its entire community and
assigns a rating. The Bank received  a "satisfactory" rating in its most  recent
CRA  review.  Both  the  United  States  Congress  and  the  banking  regulatory
authorities have proposed substantial changes to the CRA and fair lending  rules
and  regulations which, if enacted, could have  a material adverse effect on the
Company.
 
CAPITAL RESOURCES
 
    Capital management,  which is  a continuous  process at  Texas Regional  and
Texas  State  Bank, consists  of providing  equity to  support both  current and
future operations. The Company  is subject to  capital adequacy requirements  of
various  banking regulators,  such as  the FRB,  the Banking  Department and the
FDIC. At  March  31,  1996  and  December  31,  1995,  Texas  Regional  and  its
subsidiaries  were  in  compliance  with  minimum  capital  requirements  of the
respective regulatory agencies and are expected  to remain in compliance in  the
future.
 
    The  various  federal  bank  regulatory agencies,  including  the  FRB, have
adopted risk-based capital requirements for  assessing bank holding company  and
bank  capital  adequacy. These  standards define  capital and  establish minimum
capital requirements in  relation to  assets and off-balance  sheet exposure  as
adjusted  for credit risk. The risk-based  capital standards currently in effect
are  designed  to  make  regulatory  capital  requirements  more  sensitive   to
differences  in risk profile among bank  holding companies and banks, to account
for off-balance sheet exposure and to minimize disincentives for holding  liquid
assets.   Assets  and  off-balance  sheet  items  are  assigned  to  broad  risk
categories, each with  appropriate risk  weights. The  resulting capital  ratios
represent  capital as a percentage of total risk-weighted assets and off-balance
sheet items.
 
    The risk-based capital standards  as established by the  FRB apply to  Texas
Regional  and Texas State Bank. The minimum standard for the ratio of capital to
risk-weighted assets (including certain off-balance
 
                                       75
<PAGE>
sheet obligations, such as standby letters of credit) is 8.0%. At least half  of
the  risk-based capital  must consist of  common equity,  retained earnings, and
qualifying perpetual preferred stock, less  deductions for goodwill and  various
other  intangibles ("Tier  I capital").  The remainder  ("Tier II  capital") may
consist of  a  limited  amount  of subordinated  debt,  certain  hybrid  capital
instruments  and other debt securities, preferred stock, and a limited amount of
the general valuation allowance for loan losses.  The sum of Tier I capital  and
Tier II capital is "total risk-based capital."
 
    The  FRB  also  has  adopted  guidelines  which  supplement  the  risk-based
regulations to include  a minimum leverage  ratio of Tier  I capital to  average
total  consolidated assets  ("Leverage ratio") of  3.0%. The  FRB has emphasized
that the  foregoing  standards  are  supervisory minimums  and  that  a  banking
organization  will be permitted to maintain  such minimum levels of capital only
if it has  well diversified  risk, including  no undue  interest rate  exposure;
excellent  asset  quality;  high liquidity;  good  earnings; and  is  in general
considered to  be  a  strong  banking  organization,  rated  composite  1  under
applicable  federal guidelines, and the banking organization is not experiencing
or anticipating significant growth. All other banking organizations are required
to maintain a  Leverage ratio  of at  least 4.0%  to 5.0%.  These rules  further
provide  that  banking  organizations  experiencing  internal  growth  or making
acquisitions will be expected to maintain capital positions substantially  above
the  minimum supervisory levels  and comparable to  peer group averages, without
significant reliance  on intangible  assets.  The FRB  continues to  consider  a
"tangible  Tier I leverage  ratio" in evaluation proposals  for expansion or new
activities. The  tangible  Tier I  leverage  ratio is  the  ratio of  a  banking
organization's  Tier  I  capital,  less  deductions  for  intangibles  otherwise
includable in Tier I capital, to total tangible assets.
 
    Bank regulators continue to consider raising capital requirements applicable
to banking organizations beyond current  levels. However, the Company is  unable
to  predict whether higher capital  requirements will be imposed  and, if so, at
what levels and on what schedules, and therefore cannot predict what effect such
higher requirements may have on the Company and the Bank.
 
    The following table presents an analysis  of capital for Texas Regional  and
Texas State Bank at March 31, 1996 and March 31, 1995, and at the end of each of
the last three years:

  (1) Calculated  on the  basis of  the closing sale  price per  share for the
      Common Stock of $17.25 as reported by the Nasdaq National Market  System
      for December 31, 1995.
 
    The  Company  has three  stock option  plans. A  fourth plan,  the Company's
employee stock bonus plan, was terminated during January 1996. Texas  Regional's
Board  of Directors  has the  authority to  grant options  to purchase  up to an
aggregate of 262,988 shares of Common Stock under the terms of the present stock
option plans, in each case at the  then present fair market value of the  Common
Stock. One of these plans, the Texas Regional Bancshares, Inc. 1995 Nonstatutory
Stock  Option Plan,  was adopted in  1995 and  is expected to  be considered and
voted upon by the shareholders of the Company at the 1996 annual meeting of  the
shareholders.  As of the date of this Prospectus, options for the purchase of an
aggregate of 262,988 shares of Common  Stock have been granted under the  plans,
including  the options included  in the tables  above, with the  result that the
Company's Board of Directors does not have the authority to grant any additional
options to purchase Common Stock pursuant  to the stock option plans, except  to
the  extent  that  any outstanding  options  in  the future  lapse  or otherwise
terminate unexercised.
 
    In December  1993, the  Company adopted  a Deferred  Compensation Plan  (the
"Deferred  Compensation Plan") for the benefit  of Mr. Roney, which provides for
payments to be  made to  Mr. Roney  (or in  the event  of his  death during  the
period,  to his designated beneficiary or his  estate) in the amount of $100,000
per year  commencing  October  29,  2002,  and  continuing  for  fourteen  years
thereafter.  The obligation to make such payments requires Mr. Roney to continue
to be employed by the Company until October 29, 2002, unless his compensation is
reduced from  that  paid  in  1993,  his  duties  are  materially  changed,  his
employment  is terminated due  to his disability  or death, or  he is discharged
without cause. If Mr. Roney dies prior  to October 29, 2002, the payments  would
commence  immediately and be paid to  his designated beneficiary, or his estate.
At December 31, 1995, the Company had  funded, pursuant to the Trust under  Glen
E. Roney Deferred Compensation Plan, an aggregate of $291,000. The Trust was set
up  for the purpose of payment of the deferred compensation benefit. The Company
incurred expenses  of  approximately $87,000  during  each of  the  years  ended
December  31, 1995 and 1994, with respect to the Deferred Compensation Plan. See
"Business --  Personnel." In  January  1996, the  Company's Board  of  Directors
amended  the Deferred Compensation Plan and Trust  to change the identity of the
Trustee and to make  other changes designed to  assist in obtaining a  favorable
determination  letter from the Internal Revenue Service  as to the status of the
Deferred Compensation Plan for federal income tax purposes.
 
    First State  Bank has  three separate  deferred compensation  plans for  the
benefit  of three  First State  Bank employees, and  Border Bank  has a deferred
compensation plan for the  benefit of one Border  Bank employee. The plans  each
provide  for  retirement  benefits  to  be paid  to  the  specified  employee, a
designated beneficiary or the employee's estate. One plan commenced payments  to
a  retired  employee  of approximately  $13,000  per  year on  January  4, 1988,
continuing annually  thereafter until  June  2003. A  second plan  provides  for
payments  of  approximately $13,300  per  year to  commence  in April  1990, and
continuing until June 2005;  however, the employee elected  to receive a  lesser
amount  payable over a longer  period of time. The  third plan, covering Elliott
Bottom, provides for retirement benefit payment of
 
                                       83
<PAGE>
$50,000 per year commencing in March 1999 and continuing annually thereafter for
20  years.  A  fourth  plan  commenced   payments  to  a  retired  employee   of
approximately  $1,112.50  per  month in  March  1995, and  provides  for monthly
payments thereafter for 180 months. First State Bank and Border Bank own and are
beneficiaries of  life insurance  policies on  the employees  covered under  the
deferred  compensation plans, with face values in amounts approximately equal to
the total benefits  paid or payable  under the plans.  Upon consummation of  the
Mergers,  Texas  State Bank  will become  obligated to  make payments  under the
plans, and will  own and become  the beneficiary of  the related life  insurance
policies.
 
    Beginning in 1991, the Bank established a discretionary incentive bonus pool
for  the benefit of employees and directors  of the Bank. Contributions are made
to the discretionary  bonus pool based  on projected year-end  return on  assets
earned by the Bank, calculated as follows: in the event that the year-end return
on  average  assets  of  the  Bank, prior  to  any  amount  attributable  to the
discretionary bonus ("ROA") for the year is in excess of 1.00%, 2% of net income
for the year  is contributed; in  the event that  the ROA for  the year  exceeds
1.05%, in addition to the base contribution, 5% of net income in excess of 1.00%
ROA  is  contributed; if  the  ROA for  the  year exceeds  1.10%,  an additional
contribution is made in the amount of 10% of net income in excess of 1.05%  ROA.
For  each  0.05%  increase in  ROA,  the  proportion of  the  excess  net income
contributed is increased by 5% of net income, up to an ROA of 1.25%. A total  of
25%  of any amount  of net income in  excess of 1.25% ROA  is contributed to the
pool. Amounts  are  paid out  of  the  discretionary bonus  pool  to  individual
employees  and  directors of  the Bank  as  determined by  the Stock  Option and
Compensation Committee. An aggregate of $574,000 was awarded to employees of the
Bank out of the discretionary bonus pool during 1995, and $43,000 was awarded to
directors of  the Bank  that are  not employees  of the  Bank. An  aggregate  of
$375,000  was awarded to employees and  $43,000 to non-employee directors out of
the discretionary bonus pool during 1994.
 
EMPLOYEE STOCK OWNERSHIP PLAN
 
    In 1990, Texas Regional adopted the KSOP. Since adoption of the KSOP,  Texas
Regional  has made  contributions to  the KSOP,  on behalf  of employees  of the
Company, in the aggregate amount of $2.8 million, and employees have in addition
made salary  deferral contributions  to  the KSOP  in  the aggregate  amount  of
$512,000 through December 31, 1995. All Texas Regional contributions are used to
purchase  Common  Stock, and  employees have  the option  to direct  that salary
deferral contributions  (and certain  applicable  target benefit  plan  rollover
contributions) be invested either in a money market fund or in Common Stock. The
aggregate  number of  shares of  Common Stock  held pursuant  to the  KSOP as of
December 31, 1995, was 302,007 (about 4.9% of total outstanding shares of Common
Stock). All assets  in the  KSOP, including Common  Stock held  pursuant to  the
KSOP,  are held by the KSOP Trust, which  holds the shares of stock on behalf of
the employee participants in the KSOP.
 
    Trustees of  the KSOP  Trust,  who are  selected by,  and  all of  whom  are
directors  of Texas Regional, are Morris Atlas,  Frank N. Boggus, Joe M. Kilgore
and Glen E. Roney.  Employees are entitled  to direct the  voting of any  shares
allocated  to their employee accounts, and the trustees of the KSOP Trust direct
the voting of any unallocated shares held by the KSOP Trust. At March 31,  1996,
there  were 2,944  unallocated shares  held by the  KSOP Trust.  At December 31,
1995, there were  no unallocated  shares held by  the KSOP  Trust. During  1996,
management  of Texas Regional anticipates recommending to the Board of Directors
of Texas  Regional certain  amendments to  the KSOP  to make  available to  plan
participants more diverse investment options.
 
CERTAIN TRANSACTIONS
 
    Texas  State  Bank has  had,  in the  ordinary  course of  business, banking
transactions with  certain  of  its  officers and  directors  and  with  certain
officers and directors of Texas Regional. Loans by Texas State Bank to executive
officers and directors of Texas State Bank and Texas Regional, in the aggregate,
amounted  to $3.4 million at March 31,  1996, or 0.7% of total loans outstanding
and 5.3% of the shareholders' equity of the Bank and in the aggregate,  amounted
to  $4.0 million at  December 31, 1995,  or 0.9% of  total loans outstanding and
6.3% of  the  shareholders' equity  of  the  Bank. All  loan  transactions  with
officers and directors of Texas Regional and Texas State Bank, and their related
and affiliated parties, have been on
 
                                       84
<PAGE>
substantially  the same  terms as  those prevailing  for comparable transactions
with other loan  customers of  the Bank,  and have  not included  more than  the
normal  risk of collectibility associated with  Texas State Bank's other banking
transactions or other unfavorable features.
 
    Prior to 1993, the Company leased office facilities from Kerria Plaza, Ltd.,
a real estate limited partnership in which Mr. James W. Collins, former Director
and former Secretary-Treasurer of  the Company, is  general partner and  certain
principals  of the Company  own an interest. Management  of the Company believes
that the terms  of the leases  were comparable  to terms of  leases between  the
partnership  and third parties. Persons having  a direct or indirect interest in
Kerria Plaza, Ltd.,  their relationship  to the  Company and  their interest  in
Kerria  Plaza, Ltd.,  were: James  W. Collins,  individually and  as Trustee for
Carvan, Vanco and KVTC Trusts (of which Mr. Collins is not a beneficiary, but of
which his spouse and children are beneficiaries), owned a 27% interest in Kerria
Plaza, Ltd.; Glen E. Roney, Chairman of the Board and Chief Executive Officer of
the Company,  owned an  11% interest  in Kerria  Plaza, Ltd.;  Frank N.  Boggus,
former  President and a present Director of  the Company, owned a 4% interest in
Kerria Plaza, Ltd.; and Robert G. Farris, a Director of the Company, owned a  2%
interest in Kerria Plaza, Ltd.
 
    Kerria  Plaza, Ltd.  purchased the  Kerria Plaza  building in  1984. In June
1992,  the  directors  of  Texas  State  Bank  obtained  an  appraisal  from  an
independent  third party  appraiser indicating that  the market  value of Kerria
Plaza office  building was  $2.5  million. In  January  1993, Texas  State  Bank
purchased  the  Kerria Plaza  office building  from Kerria  Plaza, Ltd.  for the
appraised value of $2.5 million.
 
    Mr. Collins is  Chairman of the  Board of Rioco  Corporation, a real  estate
brokerage   and  property  management  company.  During  1995  and  1994,  Rioco
Corporation received from Texas State  Bank leasing commissions totaling  $1,237
and $1,260, respectively, resulting from leases of office space in Kerria Plaza.
Rioco  Corporation continues to manage the Kerria Plaza building for Texas State
Bank under  a property  management  agreement which  management of  the  Company
believes  is  on  terms  comparable  to  terms  available  from  other  property
management companies operating  in the area,  which management agreement,  among
other  things,  provides for  payment  of management  and  accounting fees  at a
minimum of $2,900 per month and payment  of leasing commissions in the event  of
the lease of office space in the building to third party tenants.
 
    Texas  State Bank, along  with other banks  in the Rio  Grande Valley, sells
credit life insurance for Texas State  Life Insurance Company. Texas State  Life
Insurance  Company is owned 50% by Mr.  Roney and 50% by Mr. Collins. Commission
fee income received by Texas State Bank from Texas State Life Insurance  Company
totaled $82,475 for the year ended December 31, 1995.
 
    Mr.  Joe M. Kilgore, a Director of the Company, is a partner in the law firm
of McGinnis,  Lochridge &  Kilgore,  L.L.P. His  firm  received fees  for  legal
services  rendered to the Company and its subsidiary during 1995, but the amount
of fees received did not exceed either 5% of his firm's gross revenues for  1995
or 5% of Texas Regional's total operating expenses for the year ended 1995.
 
    Mr. Morris Atlas, a Director of the Company, is a partner in the law firm of
Atlas  & Hall, L.L.P. His firm received  fees for legal services rendered to the
Company and its subsidiary during 1995, but the amount of fees received did  not
exceed either 5% of his firm's gross revenues for 1995 or 5% of Texas Regional's
total operating expenses for the year ended 1995.
 
    During  1995, Texas State Bank purchased a tract of real estate from Scott &
White Memorial  Hospital and  Scott, Sherwood  & Brindley  Foundation ("Scott  &
White"),  a Texas non-profit corporation, for $227,000. Texas State Bank intends
to hold the property for possible future development as a banking location.  Mr.
Roney and Mr. Kilgore each serve as members of the Board of Directors of Scott &
White.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    Texas Regional is authorized to issue 20,000,000 shares of Common Stock, and
10,000,000  shares  of Preferred  Stock with  such preferences,  limitations and
relative rights as may be determined by  the Board of Directors of the  Company.
Prior  to April  1991, the  Company had  authority to  issue Class  B Non-Voting
Common Stock as well. The Class B Non-Voting Common class was created to provide
a mechanism  for  equalizing  consideration  to  shareholders  at  the  time  of
acquisition  of  Texas  State  Bank  and  Harlingen  State  Bank  in  1983.  All
outstanding shares of Class B Non-Voting Common Stock were converted into  Class
A  Voting Common shares  in April 1991, and  the class of  shares referred to as
Class B Non-Voting Common Stock was eliminated. As used herein, the term "Common

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    After completion  of  this  offering,  the  Company  will  have  outstanding
8,706,791  shares  of Common  Stock (assuming  election  by the  Underwriters to
purchase shares subject  to the Underwriters'  over-allotment option). Of  these
shares,  the 2,510,000 shares  of Common Stock sold  in this offering (including
such over-allotment  shares)  will be  freely  tradable without  restriction  or
limitation under the Securities Act except to the extent such shares are subject
to  the  agreement with  the Underwriters  described below,  and except  for any
shares purchased by "affiliates" of the Company, as that term is defined in  the
Securities  Act.  In  addition,  an  aggregate  of  4,811,531  shares  presently
outstanding are also not restricted
 
                                       89
<PAGE>
and, under certain  conditions, may  be freely tradable  without restriction  or
limitation  under  the  Securities  Act.  The  remaining  1,385,260  shares  are
"restricted" shares within the meaning of Rule 144 adopted under the  Securities
Act  ("Rule 144").  Restricted shares  outstanding on  the date  hereof owned by
"affiliates" may only be sold if they are registered under the Securities Act or
unless an exemption  from registration, such  as that provided  by Rule 144,  is
available.
 
    The   Company,  its  executive  officers,  its  directors  and  the  Selling
Shareholder have agreed not,  directly or indirectly, to  offer, sell, offer  to
sell, contract to sell, grant any option to purchase or otherwise dispose of (or
announce  any offer, sale, offer of sale,  contract of sale, grant of any option
to purchase or  any other disposition  of), any  shares of Common  Stock or  any
securities  convertible  into or  exchangeable,  or exercisable  for,  shares of
Common Stock  for a  period  of 120  days after  the  date of  the  Underwriting
Agreement  without the prior written consent of the Underwriters (the "Lockup").
Following the  Lockup, these  shares will  be eligible  for sale  in the  public
market,  subject to the conditions  and restrictions of Rules  144 and Rule 144A
also adopted under the Securities  Act ("Rule 144A"), as hereinafter  described.
See "Underwriting."
 
    No  prediction can be  made as to the  effect, if any,  that market sales of
shares or the  availability of shares  for sale  will have on  the market  price
prevailing  from time  to time.  Nevertheless, sales  of substantial  amounts of
Common Stock in the public market after the lapse of the restrictions  described
above  could adversely affect the prevailing market price and the ability of the
Company to raise equity capital in the future at a time and price which it deems
appropriate.
 
    In general, under Rule  144 as currently in  effect, any person (or  persons
whose shares are aggregated), including an affiliate, who has beneficially owned
Restricted Shares for at least a two-year period (as computed under Rule 144) is
entitled to sell within any three-month period a number of such shares that does
not  exceed the greater of (i) 1% of the then outstanding shares of Common Stock
(approximately 87,000 shares after giving effect to this offering, assuming  the
Underwriters  exercise the available over-allotment option in full) and (ii) the
average weekly trading volume in the Common Stock on the Nasdaq National  Market
System  during the  four calendar weeks  immediately preceding  such sale. Sales
under Rule 144 are also subject to certain provisions relating to the manner and
notice of sale  and the  availability of  current public  information about  the
Company.  A person (or persons whose shares are aggregated) who is not deemed an
affiliate of the Company at any time during the 90 days immediately preceding  a
sale, and who has beneficially owned Restricted Shares for at least a three-year
period (as computed under Rule 144), would be entitled to sell shares under Rule
144(k)  without regard to  the volume limitation  and other conditions described
above. Restricted  Shares and  options  to purchase  Common  Stock sold  by  the
Company  to, among  others, its  employees, officers  and directors  pursuant to
written compensation plans or  contracts and in reliance  on Rule 701 under  the
Securities  Act, may be resold  in reliance on Rule 144  by such persons who are
not affiliates subject only  to the provisions of  Rule 144 regarding manner  of
sale,  and by such persons who are  affiliates without complying with Rule 144's
holding period requirements. Rule 144A permits the immediate sale by the current
holders of Restricted  Shares of all  or a  portion of their  shares to  certain
qualified institutional buyers as defined in Rule 144A.

on the same terms as those on which the 2,200,000 shares are being offered.

Texas Regional Bancshares, Inc. and Subsidiary
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- BASIS OF PRESENTATION
 
The  accompanying unaudited consolidated financial statements have been prepared
in accordance with the  instructions to Form 10-Q  and therefore 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  unaudited 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
unaudited  consolidated financial statements  include Texas Regional Bancshares,
Inc. and its subsidiary (the "Company"). Intercompany balances and  transactions
have been eliminated.
 
NOTE 2 -- EARNINGS PER COMMON SHARE COMPUTATIONS
 
Earnings  per  common share  computations include  the  effects of  common stock
equivalents applicable to the stock option contracts.
 
NOTE 3 -- 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 effect  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 4 -- COMMON STOCK
 
On  March  12, 1996,  the Board  of Directors  approved a  $0.10 per  share cash
dividend for shareholders of record  on April 8, 1996  and payable on April  15,
1996.
 
NOTE 5 -- ACQUISITION ACTIVITY
 
On  January 10,  1996, the Company  announced agreements have  been signed under
which Texas State  Bank, the  principal operating subsidiary  of Texas  Regional
Bancshares,  Inc., will  acquire through  merger First  State Bank  & Trust Co.,
Mission, Texas,  and  The  Border  Bank, Hidalgo,  Texas  (the  "Mergers").  The
agreements  have been approved  by the appropriate Boards  of Directors of Texas
Regional Bancshares, Inc., Texas  State Bank, First State  Bank & Trust Co.  and
The  Border  Bank. Under  the terms  of  the agreements,  Texas State  Bank will
acquire First State Bank  & Trust Co.  for a total  cash consideration of  $79.0
million and will acquire The Border Bank for a total cash consideration of $20.5
million.
 
The  following  Pro Forma  Combined  Condensed Balance  Sheet  was based  on the
assumption that the Mergers had been consummated on March 31, 1996. The  Mergers
will be accounted for using the purchase method of accounting.
 
The  Mergers are  subject to completion  of satisfactory due  diligence by Texas
Regional Bancshares, Inc.  and must  be approved  by the  shareholders of  First
State  Bank & Trust Co.  and The Border Bank. The  Mergers have been approved by
the appropriate  regulators.  Closing is  also  contingent upon  Texas  Regional
Bancshares,  Inc. having successfully raised $40.0 million of additional capital
to partially fund these transactions on terms and conditions acceptable to Texas
Regional Bancshares, Inc.
 
During August 1995,  the Bank  acquired two branch  bank locations,  one in  Rio
Grande  City,  Texas,  and  the  other  in  Roma,  Texas  (the  "RGC/Roma Branch
Acquisitions"). The transaction included the purchase of $43.7 million in  loans
and  the assumption  of approximately  $79.7 million  in deposit  liabilities of
these branches.  Investment securities  were not  acquired. Purchase  accounting
adjustments  for the purchase of loans and the assumption of deposit liabilities
of the  RGC/Roma  Branch  Acquisitions were  immaterial.  This  transaction  was
accounted for as a purchase.
 
                                      F-6
<PAGE>
The  Company's Consolidated  Balance Sheet  at December  31, 1995  reflected the
assets and liabilities  of the  RGC/ Roma  Branch Acquisitions.  The results  of
operations  of the RGC/Roma  Branch Acquisitions were  included in the Company's
Consolidated Financial Statements from the date of acquisition.
 
The following Unaudited Pro  Forma Combined Condensed  Statements of Income  for
the  three months ended March 31, 1996 and for the year ended December 31, 1995,
assumes the Mergers  and the  RGC/Roma Branch Acquisitions  occurred January  1,
1995.  Intangibles arising from the Mergers and RGC/Roma Branch Acquisitions are
approximately $19.7  million  and  $4.1 million,  respectively.  The  pro  forma
adjustments  reflect the amortization of the Core Deposit premium over a 10-year
period, the Fixed Maturity Deposit premium over a 3-year period and the Goodwill
intangible over  a 15-year  period, the  reduced interest  income on  the  $54.3
million  net purchase price ($99.5 million less $45.2 million) of the Mergers at
an average federal funds sold rate of 5.11% for the three months ended March 31,
1996 and 5.92% for the  year ended December 31,  1995, respectively and the  tax
effect of the prior two transactions using an effective tax rate of 35% for 1996
and  an  effective tax  rate  of 34%  for  1995. The  pro  forma results  do not
necessarily represent the actual results that would have occurred and should not
be considered indicative of future results of operations.

    The unaudited pro forma combined condensed balance sheet combines the  three
entities at March 31, 1996. In combining the entities, the following adjustments
were made:
 
(A)  To record the proceeds of the  $45.2 million net capital raised through the
    offering based on  an assumed  sale of 2,180,000  shares of  Class A  Voting
    Common Stock for the offering price of $22.25 per share, net of underwriting
    discounts, commissions and other estimated offering expenses.
 
(B) To record the elimination of intercompany demand deposit accounts.
 
(C)  To record  estimated $7.0  million increase in  fair market  value of fixed
    assets.
 
(D) To record estimated deferred federal income tax on the net fair market value
    increases.
 
(E) To record the payment  of $99.5 million to the  First State Bank and  Border
    Bank  shareholders for 100%  of their outstanding  stock, elimination of all
    First State  Bank and  Border  Bank equity  accounts  and the  recording  of
    goodwill.
 
(F) To adjust loan carrying value to estimated fair value.
 
(G) To record estimated fair value of core deposits.
 
(H) To record estimated fair value of fixed maturity deposit premium.
 
(I) To reclassify deferred federal income taxes.
 
    The  unaudited pro forma  condensed statements of  income combined the three
entities for the three months ended March  31, 1996 and the year ended  December
31, 1995. In combining the entities, the following adjustments were made:
 
(J)  To record a reduction in interest  income on the $54.3 million net purchase
    price ($99.5  million less  $45.2  million) of  the  Mergers at  an  average
    federal funds sold rate of 5.11% for the three months ended March 31, 1996.
 
    To  record a reduction in interest income  on the $54.3 million net purchase
    price ($99.5 million less  $45.2 million) of the  Mergers and $4.25  million
    purchase  price of  the RGC/Roma Branch  Acquisitions at  an average federal
    funds sold rate of 5.92% for the year ended December 31, 1995.
 
(K) To amortize the fixed maturity deposit premium.
 
(L) To record depreciation on fair  market value increases of depreciable  fixed
    assets acquired in the Mergers.
 
(M)  To record amortization of the goodwill and core deposit premium recorded in
    connection with the Mergers and the RGC/Roma Branch Acquisitions.
 
(N) To record the  effect of the  pro forma adjustments  using an effective  tax
    rate  of 35% for the three months ended  March 31, 1996 and an effective tax
    rate of 34% for the year ended December 31, 1995.

Company's management.  Our responsibility  is  to express  an opinion  on  these

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1995, 1994 AND 1993
 
(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    The  accounting and  reporting policies  of Texas  Regional Bancshares, Inc.
(the "Parent"  or "Corporation")  and subsidiary  (collectively, the  "Company")
conform  to generally accepted accounting principles and to prevailing practices
within  the  banking  industry.  The  preparation  of  financial  statements  in
conformity  with generally accepted accounting principles requires management to
make estimates and assumptions  that affect the reported  amounts of assets  and
liabilities  and 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 Texas Regional
Bancshares,  Inc.  (the "Corporation")  and its  wholly owned  subsidiary, Texas
State  Bank  (the  "Bank"),   collectively  (the  "Company").  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.
 
TRUST ASSETS
 
    Assets  held by the trust department of  the subsidiary bank in fiduciary or
agency capacities  are not  assets of  Texas Regional  Bancshares, Inc.  or  its
subsidiary and are not included in the consolidated balance sheets.
 
INVESTMENT SECURITIES
 
    In  May  1993,  the  Financial Accounting  Standards  Board  ("FASB") issued
Statement  of  Financial  Accounting   Standards  No.  115  ("Statement   115"),
"Accounting  for Certain Investments  in Debt and  Equity Securities." Statement
115 establishes standards of financial accounting and reporting for  investments
in  equity securities that  have a readily  determinable fair value  and for all
investments in debt 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 balance sheet 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 balance sheet 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 balance sheet
with unrealized holding  gains and losses  reported in a  separate component  of
shareholders' equity until realized.
 
    Effective December 31, 1993, the Company adopted Statement 115, which caused
various  investment  securities  to be  reclassified  from Held  to  Maturity to
Available for Sale. All treasury and agency  bonds with a maturity of two  years
or  less from December  31, 1993, all  floating rate bonds  and two small equity
securities were reclassified to Available for Sale. As a result, at December 31,
1993 the Company recorded  an increase in shareholders'  equity of $179,000,  as
unrealized  holding  gains. Future  purchases of  investment securities  will be
classified as Available  for Sale or  Held to  Maturity at time  of purchase  as
determined  by  the  investment committee.  At  December  31, 1995  and  1994 no
securities were classified as Trading.
 
    On October 18, 1995, the  FASB decided to grant  to all entities a  one-time
opportunity  during the period  from approximately mid  November to December 31,
1995, to reconsider their intent and ability to hold securities accounted for as
Held to  Maturity  under  Statement  115.  This  allowed  entities  to  transfer

securities  from the Held to Maturity category  to Available for Sale or trading
without calling into  question their  intent to  hold other  debt securities  to
maturity.  On December 31, 1995, the Bank transferred approximately $1.5 million
in Held to Maturity securities to  the Available for Sale category resulting  in
no  change to stock  equity per share. As  a result of  this transfer, all other
securities are classified as Available for Sale.
 
LOANS
 
    Loans are  stated  at the  principal  amount outstanding,  net  of  unearned
discount.   Interest   income  on   discounted  loans   is  recognized   on  the
sum-of-the-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.
 
LOAN FEES
 
    Loan origination fees and certain direct loan origination costs are deferred
and  recognized over the lives of the related loans as an adjustment of the loan
yields.
 
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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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 Company
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  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. The provision  for loan losses is based on
management's estimate of the amount  required to maintain an allowance  adequate
to  absorb  potential  losses  in  the  loan  portfolio.  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
 
    The Company  files a  consolidated federal  income tax  return. The  Company
establishes  a deferred  tax asset  or liability  for the  recognition of future
deductions or taxable amounts and operating loss and tax credit  carry-forwards.
Deferred  tax expense or benefit is recognized as  a result of the change in the
asset or liability during the year.
 
EARNINGS PER SHARE COMPUTATIONS
 
    Primary earnings  per  share  are  computed  by  dividing  net  income  less
preferred  stock dividends,  if any,  by the  weighted average  number of common
stock and common stock equivalents outstanding during the period,  retroactively
adjusted  for  stock  splits  effected  as  a  stock  dividend.  The convertible
preferred stock did not satisfy the  criteria for consideration as common  stock
equivalents.
 
    Fully diluted earnings per share is computed as if all convertible preferred
stock had been converted to common stock.
 
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.

    In the ordinary course of business, the Company's subsidiary bank made 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. An analysis of these loans for  the years ended December 31, 1995  and
December 31, 1994 follows:

    For  the years ended December  31, 1995 and December  31, 1994, the deferred
tax  liability  results  primarily  from  the  use  of  accelerated  methods  of
depreciation  of equipment for  tax purposes and the  write-off of core deposits
for book purposes. The  deferred tax asset results  from differences in the  bad
debts  written-off for financial purposes and  the amount allowed under tax law,
and a difference  in other real  estate basis due  to write-downs for  financial
statement   purposes  for  both   years  ended  December   31,  1995  and  1994,
respectively.
 
    The valuation allowance was established to reduce the amount that will  more
likely  than not be realized  due to increased recoveries  in allowance for loan
losses.

    The  Corporation's First Series Convertible  Preferred Stock and Series 1990
Convertible Preferred Stock were issued in 1989 and 1990, respectively, for cash
equal to the  stated value  of $100.00 per  share. The  Series 1991  Convertible
Preferred  Stock was issued in 1991 in connection with the Company's acquisition
of Mid Valley Bank of  Weslaco, Texas. The shares  of First Series, Series  1990
and Series 1991 Preferred Stock ranked on a parity with each other, and superior
to  the Class  A Voting  Common Stock  of the  Corporation, as  to dividends and
liquidation  preference.  Shares  of  each   series  of  Preferred  Stock   were
convertible into shares of Class A Voting Common Stock of the Corporation.
 
    On  March 21, 1994, the Board of  Directors adopted a resolution calling for
the redemption on April 22, 1994, of all issued and outstanding Preferred  Stock
at a redemption price of $104.00 per share plus all accrued and unpaid dividends
through  the date fixed  for redemption. At  that time, the  Preferred Stock was
convertible into 13.2 shares of  Class A Voting Common  Stock for each share  of
Preferred  Stock held. Effective  April 22, 1994, 356  shares of Preferred Stock
were redeemed for cash and 74,172 shares of Preferred Stock were converted  into
979,009  shares of Class A Voting Common Stock.  As a result, as of December 31,
1994, there were no shares of Preferred Stock outstanding.
 
    Pursuant to the Texas  Business Corporation Act, the  Board of Directors  of
the  Corporation has the authority  to eliminate any series  of shares which the
Board has authority to establish, if there are no shares outstanding or held  as
treasury  shares. Upon adoption  of a resolution eliminating  the series and all
references to the series,  the shares resume status  as authorized but  unissued
shares of Preferred Stock for which the Board has the authority to determine the
designations, preferences, limitations and relative rights.
 
    On  February 14, 1995, the Board of  Directors of the Corporation approved a
resolution to  eliminate  the  series  of  shares  known  as  the  First  Series
Convertible Preferred, the Series 1990 Convertible Preferred and the Series 1991
Convertible  Preferred shares of  the Corporation, and  further provided for the
elimination of all references thereto from  the Articles of Incorporation. As  a
result  of the elimination of the series  of Preferred shares, the shares resume
status as authorized but unissued shares of Preferred Stock for which the  Board
has  the authority to  determine the designations,  preferences, limitations and
relative rights.

(10)  COMMON STOCK
    On  March  16, 1994,  the  Corporation completed  a  public offering  of 1.2
million shares of the Corporation's Class  A Voting Common Stock at an  offering
price  of $12.00  per share, and  contemporaneously listed the  Common Stock for
trading in the NASDAQ  Stock Market's National Market  System under the  trading
symbol  "TRBS." In the  offering, the Corporation sold  one million newly issued
shares and an aggregate of 200,000 shares were sold on behalf of certain selling
shareholders of the  Corporation. As  a part  of the  offering, the  Corporation
granted  the Underwriters  an option, exercisable  within 30  days following the
date of the Underwriting Agreement, to purchase up to 180,000 additional  shares
of  Corporation Class A Voting Common  Stock solely to cover over-allotments. On
April 15,  1994, the  Underwriters exercised  this option  and purchased  28,291
additional shares of Class A Voting Common Stock.
 
    On  May 11, 1993, the Board of Directors approved a 20% stock split effected
as a stock dividend to Class A Voting Common Stock shareholders of record on May
11, 1993, with any fractional shares resulting from such stock split to be  paid
in cash based on a value of $10.00 per share.
 
(11)  EMPLOYEE BENEFITS
    In  1984,  the  Company  adopted  a  target  benefit  pension  plan covering
substantially all of their  employees. In December,  1990, the Company  restated
its  target  benefit pension  plan  as an  Employee  Stock Ownership  Plan (with
section 401(k)  provisions)  (the  "KSOP"). The  Company  received  a  favorable
determination  letter on  July 29, 1993,  in which the  Internal Revenue Service
stated that  the  plan, as  designed,  was  in compliance  with  the  applicable
requirements  of the Internal  Revenue Code. Employer  contributions to the KSOP
are discretionary, and as such, determined  at the sole discretion of the  Board
of  Directors. The KSOP  covers employees who  have completed twelve consecutive
months of credited  service, as  defined in  the plan,  and attained  age 21.  A
participant's  account balance will be fully  vested after six years of credited
service. The purpose  of the restatement  is to permit  employees to acquire  an
equity  interest in  the Company  through the  KSOP's purchase  of common stock.
Pension expense, which includes  Employer matching as  discussed below, for  the
years  ended  December  31, 1995,  1994  and  1993 was  $526,000,  $462,000, and
$570,000, respectively.
 
    A Participant of  the KSOP may  authorize the Company  to contribute to  the
Trust  on  his  behalf  Salary Reduction  Contributions.  Such  Salary Reduction
Contributions shall be stated as a whole  percentage and shall not be less  than
1%  or more  than 15%  of the  Participant's compensation.  The total  amount of
Salary Reduction  Contributions  for any  Plan  Year shall  not  exceed  $7,000,
multiplied  by any cost of living  adjustment factor prescribed by the Secretary
of the Treasury under Section 415(d) of the Code. Such contributions are matched
at the discretion  of the  Board of Directors  up to  a maximum of  100% of  the
Participant's   Salary  Reduction   Contribution  and   shall  be   based  on  a
Participant's Salary Reduction Contribution  of up to  4% of such  Participant's
compensation.  The Participant's and Employer  matching contributions are vested
immediately.
 
    In March 1986, the shareholders of the Company approved three separate stock
plans involving the Class A Voting  Common Stock, providing for the issuance  of
up  to 253,434  shares to  certain key employees  for their  purchase and 10,000
shares as part of  a bonus plan  for employees of the  Company. One option  plan
provides  for sale of up  to 126,717 shares to the  chief executive officer at a
price to be determined by a committee of directors on the date of grant; another
provides for sale of up to 126,717 shares  at fair market value at the date  the
options  are  granted  to key  employees  of  the Company,  excluding  the chief
executive officer.  The  third plan  provides  for up  to  10,000 shares  to  be
distributed  as  employee  bonuses  without  payment  of  consideration  by  the
employees. The third plan was terminated effective January 9, 1996.

been  exercised or the expiration date of  the option, whichever is earlier. The
options to acquire 49,433 Class A Voting Common Stock were awarded May 10, 1994,

maximum of 90,000 shares of the Class A Voting Common Stock of the  Corporation,
subject  to adjustment for stock dividends, stock splits and upon the occurrence
of other events as specified in the Plan. The Board of Directors has recommended
the Plan to the shareholders of the Corporation and has authorized and  directed
the  officers of  the Corporation  to submit  the Plan  to the  shareholders for
approval at  the next  regular or  special meeting  of the  shareholders of  the
Corporation.  In addition, options to acquire up to 90,000 Class A Voting Common
shares at $17.25 per share were granted to certain key employees of the  Company
pursuant  to the Plan including options to acquire 65,000 shares granted to Glen
E. Roney.  Options to  purchase one-fourth  of the  shares as  granted shall  be
exercisable  commencing on the later of July 1, 1996, or the date of approval of
the Plan by the shareholders of the Corporation, and (provided that the Plan has
received the  approval  of  the  shareholders of  the  Corporation)  options  to
purchase  an additional  one-fourth of the  shares as granted  pursuant to these
resolutions shall be exercisable beginning July  1 of each year thereafter,  and
in  each case options  to purchase shares granted  pursuant to these resolutions
shall thereafter be exercisable at  any time prior to  July 1, 2002, subject  to
other provisions applicable to such options as specified in the Plan.

    Effective  as  of  December  14,  1993,  the  Company  adopted  a   Deferred
Compensation  Plan for the  benefit of Glen E.  Roney. The Deferred Compensation
Plan provides for a retirement benefit  payable to Mr. Roney (or his  designated
beneficiary  or his estate if Mr. Roney dies prior to payment of the full amount
of deferred compensation) of $100,000 per year commencing October 29, 2002,  and
continuing  annually thereafter for  fourteen years. If Mr.  Roney dies prior to
commencement of the retirement benefit, payments would commence immediately  and
be  paid to his designated  beneficiary or his estate.  The Company also adopted
the Trust Under Glen E. Roney Deferred Compensation Plan, in the form prescribed
by  applicable  regulations  adopted  by   the  Internal  Revenue  Service   for
nonqualified deferred compensation plans. Among other things, the Plan and Trust
provide  for an  initial deposit  into the Trust  by the  Company and subsequent
deposits in the discretion  of the Board of  Directors, and further provide  for
full  funding of the amount necessary to discharge the retirement benefit in the
event of a change of control, as that term is defined in the Trust. The  Company
has  incurred  Deferred  Compensation  expense and  has  funded  into  the Trust
$87,000, $87,000 and  $116,000 respectively,  for the years  ended December  31,
1995, 1994 and 1993, respectively.
 
(12)  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.
 
    At December  31, 1995,  the Company  had outstanding  commitments to  extend
credit  of approximately $79.0 million which  included standby letters of credit
of approximately $2.6 million.  Management does not anticipate  any losses as  a
result of these commitments.
 
    Future  minimum lease payments  on operating leases as  of December 31, 1995
are as follows:

DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    Statement  of  Financial  Accounting Standards  No.  107  ("Statement 107"),
"Disclosures about Fair Value Instruments",  requires that the Company  disclose
estimated  fair  values for  its  financial instruments.  Fair  value estimates,
methods and  assumptions  are  set  forth  below  for  the  Company's  financial
instruments.
 
DEBT SECURITIES
 
    For  securities held as investments, fair  market value equals quoted market
price, if available. If a  quoted market price is  not available, fair value  is
estimated using quoted market prices for a similar security.
 
    Investments  not classified as Held to Maturity or Trading are classified as
Available for Sale and measured at fair value in the consolidated balance sheets
with unrealized holding  gains and losses  reported as a  separate component  of
shareholders' equity until realized.
 
    The  following table presents the amortized cost and estimated fair value of
securities classified as Available for Sale at December 31, 1995:

LOANS
 
    The  Company does  not consider its  loan portfolio to  have the homogeneous
categories of loans for which the fair value could be estimated by using  quoted
market  prices for securities backed by similar loans. Therefore, the fair value
of all loans  is estimated by  discounting future cash  flows using the  current
rates  at which  similar loans  would be made  to borrowers  with similar credit
ratings for the  same remaining maturities.  Assumptions regarding credit  risk,
cash flows and discount rates are judgmentally determined using available market
information and specific borrower information.

    The fair value of demand deposits, savings accounts and certain money market
deposits is the amount payable on demand  at the reporting date. The fair  value
of  certificates of deposit is based on the discounted value of contractual cash
flows. The discount  rate is  estimated using  the rates  currently offered  for
deposits  of  similar remaining  maturities.  The following  table  presents the

COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT AND FINANCIAL GUARANTEES
WRITTEN
 
    These financial  instruments are  not  sold or  traded, and  estimated  fair
values  are not readily available. The  carrying amount of commitments to extend
credit and standby  letters of credit  is the net  unamortized deferred cost  or
income arising from these unrecognized financial instruments. The estimated fair
value  of these  commitments is considered  to be the  carrying value. Financial
guarantees written consist  of obligations  for credit cards  issued to  certain
customers.  Substantially all of the  liability for financial guarantees written
is collateralized by deposits pledged to the Company.

LIMITATIONS
 
    Fair value estimates are made at a specific point in time, based on relevant
market  information  and  information  about  the  financial  instrument.  These
estimates do not reflect any premium or discount that could result from offering
for sale at  one time the  Company's entire holdings  of a particular  financial
instrument.  Because no market exists for a significant portion of the Company's
financial instruments, fair  value estimates  are based  on judgments  regarding
future   expected   loss   experience,   current   economic   conditions,   risk
characteristics of  various  financial  instruments  and  other  factors.  These
estimates  are subjective  in nature  and involve  uncertainties and  matters of
significant judgment and therefore cannot be determined with precision.  Changes
in assumptions could significantly affect the estimates.
 
    Fair  value  estimates  are  based on  existing  on-  and  off-balance sheet
financial instruments without  attempting to estimate  the value of  anticipated
future  business and the value of assets and liabilities that are not considered
financial  instruments.  For  example,  the  Company  has  a  substantial  trust
department that contributes net fee income annually. The trust department is not
considered  a financial instrument, and its value has not been incorporated into
the fair value estimates. Other significant assets and liabilities that are  not
considered financial assets or liabilities include the deferred tax liabilities,
property,  plant,  equipment and  goodwill. In  addition, the  tax ramifications
related to  the  realization of  the  unrealized gains  and  losses can  have  a
significant  effect on fair value estimates and have not been considered in many
of the estimates.
 
(16)  ACQUISITION ACTIVITY
    On January 10, 1996, the  Company announced definitive agreements have  been
signed  under which Texas State Bank,  the principal operating subsidiary of the
Corporation, will  acquire through  merger the  First State  Bank &  Trust  Co.,
Mission,  Texas,  and  The  Border Bank,  Hidalgo,  Texas  (the  "Mergers"). The
definitive agreements have been approved by the appropriate Boards of  Directors
of  the Corporation,  Texas State  Bank, First  State Bank  & Trust  Co. and The
Border Bank. Under the terms of the definitive agreements, Texas State Bank will
acquire First State Bank  & Trust Co.  for a total  cash consideration of  $79.0
million and will acquire The Border Bank for a total cash consideration of $20.5
million.
 
    The  following pro forma  combined condensed balance sheet  was based on the
assumption that the acquisition had been  consummated on December 31, 1995.  The
Mergers will be accounted for using the purchase method of accounting.
 
    The  Mergers are subject to completion  of satisfactory due diligence by the
Corporation and must be approved by the shareholders of First State Bank & Trust
Co. and The Border Bank.  The Mergers must also  be approved by the  appropriate
regulators.  Closing is also contingent upon the Corporation having successfully
raised $40.0 million of additional capital to partially fund these  transactions
on terms and conditions acceptable to the Corporation.

Acquisitions").  The transaction included the purchase of $43.7 million in loans
and the  assumption of  approximately $79.7  million in  deposit liabilities  of
these  branches. Investment  securities were  not acquired.  Purchase accounting
adjustments for the purchase of loans and the assumption of deposit  liabilities
of  the  RGC/Roma  Branch  Acquisitions were  immaterial.  This  transaction was
accounted for as a purchase.
 
    The Company's consolidated balance sheets at December 31, 1995 reflected the
assets and  liabilities of  the  RGC/Roma Branch  Acquisitions. The  results  of
operations  of the RGC/Roma  Branch Acquisitions were  included in the Company's
consolidated financial statements of income from the date of acquisition.
 
    The following unaudited  pro forma combined  condensed statements of  income
for  the years  ended December  31, 1995  and 1994,  assume the  Mergers and the
RGC/Roma Branch Acquisitions occurred January 1, 1994. Intangibles arising  from
the Mergers and RGC/Roma Branch Acquisitions are approximately $19.9 million and
$4.1  million, respectively. The pro  forma adjustments reflect the amortization
of the core deposit  premium over a 10-year  period, the fixed maturity  deposit
premium  over a 3-year period and the goodwill intangible over a 15-year period.
The pro forma results do not necessarily represent the actual results that would
have occurred  and should  not be  considered indicative  of future  results  of
operations.

                          FIRST STATE BANK & TRUST CO.
          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    The  following  discussion  provides  additional  information  regarding the
financial condition and the results of  operations for First State Bank for  the
three  months ended  March 31,  1996 and 1995  and for  each of  the years ended
December 31, 1995, 1994 and 1993. This discussion should be read in  conjunction
with  the  financial  statements  of  First State  Bank  and  the  notes thereto
appearing elsewhere in this prospectus.
 
SELECTED FINANCIAL INFORMATION
 
    Net income for the  three months ended  March 31, 1996  was $2.3 million  or
$11.39  per share  compared to $2.7  million or  $13.54 per share  for the three
months ended March 31, 1995. Earnings for the three months ended March 31,  1996
were  below the same period of the  prior year because of an increased provision
for loan losses and other noninterest expenses.
 
    Net income for the year ended December 31, 1995 was $8.6 million, a decrease
of 2.2% compared to net income of  $8.8 million for the year ended December  31,
1994.  The earnings  per share of  $43.23 for  the year ended  December 31, 1995
decreased $0.98 or 2.2% compared  to earnings per share  of $44.21 for the  year
ended December 31, 1994.
 
    Return  on average assets for 1995 was 2.12%, compared to 2.15% for 1994 and
1.99% for 1993.  Return on  average stockholders'  equity was  15.28% for  1995,
compared to 17.13% for 1994 and 17.20% for 1993.
 
    Earnings  performance for the year ended December 31, 1995 reflected a small
increase in net  interest income  offset by an  increase in  provision for  loan
losses.  The increase  in net interest  income for 1995  resulted primarily from
higher interest rates.
 
                       ANALYSIS OF RESULTS OF OPERATIONS
 
NET INTEREST INCOME
 
    Taxable-equivalent net interest income was $5.2 million for the three months
ended March 31, 1996, a decrease of  $94 thousand or 1.8% compared to the  three
months  ended March 31, 1995 of $5.3  million. The interest rate margin of 5.37%
for the three months ended March 31, 1996 reflects a decrease of 26 basis points
compared to 5.63% for the three months ended March 31, 1995. The decrease in net
interest income for the three months ended March 31, 1996 compared to the  three
months  ended March 31, 1995 was primarily attributable to changes in the mix of
interest-earning assets and higher rates paid on interest-bearing deposits.
 
    Taxable-equivalent net interest income was $20.7 million for the year  ended
December  31, 1995, an  increase of $101  thousand or 0.5%  compared to the year
ended December  31, 1994  and taxable-equivalent  net interest  income of  $20.6
million  for the year  ended December 31,  1994 increased $204  thousand or 1.0%
compared to the year ended December 31, 1993.
 
    The net yield on interest-earning assets, also referred to as interest  rate
margin,  represents  net  interest income  divided  by  average interest-earning
assets. The net interest margin  of 5.40% for the  year ended December 31,  1995
increased 6 basis points compared to 5.34% for the year ended December 31, 1994.
The  net interest rate  margin for the  year ended December  31, 1994 reflects a
decrease of 6 basis points from the 5.40% for the year ended December 31, 1993.
 
    Average interest-earnings assets  declined $2.1  million or  0.6% to  $383.1
million  for the year ended December 31,  1995. Small declines in commercial and
consumer loans and federal funds sold were partially offset by increases in real
estate loans  and investments.  Average interest-earning  assets increased  $8.0
million  or 2.1%  to $385.3 million  for the  year ended December  31, 1994. The
increase in average  interest-earning assets  for 1994  resulted primarily  from
increases  in investment securities  of $11.5 million and  loans of $4.2 million
offset by a decline in federal funds sold.
 
                                      F-43

    Average interest-earning assets comprised 93.8%  of average total assets  in
1995, compared to 93.8% in 1994 and 92.9% in 1993.
 
    Average  interest-bearing deposits declined $10.0  million or 3.1% to $308.6
million for the  year ended December  31, 1995  compared to a  decrease of  $979
thousand  or 0.3% to $318.5 million for  the year ended December 31, 1994. These
changes in  the mix  of interest-earning  assets and  interest-bearing  deposits
caused  the  ratio of  interest-bearing deposits  to interest-earning  assets to
decline to 80.5% in 1995, compared to 82.7% in 1994 and 84.7% in 1993.
 
    Average noninterest-bearing deposits increased $2.3 million or 6.0% to $40.2
million in 1995 compared to an increase of $1.1 million or 2.9% to $38.0 million
in 1994.  The ratio  of average  noninterest-bearing deposits  to average  total
deposits was 11.5% for 1995, compared to 10.6% for 1994 and 10.3% for 1993.

    The  following table presents for the three  months ended March 31, 1996 and
1995, the total dollar amount  of interest income from average  interest-earning
assets  and resultant yields, reported on a taxable-equivalent basis, as well as
the interest-bearing liabilities, expressed both  in dollars and rates.  Average
balances  are  derived  from  weekly  balances  and  the  yields  and  costs are
established by dividing income or expenses  by the average balance of the  asset
or  liability. Income  and yield on  interest-earning assets  include amounts to
convert  tax-exempt  income  to  a  taxable-equivalent  basis,  assuming  a  34%
effective income tax rate.

    The following table  presents for the  last three calendar  years the  total
dollar  amount of interest  income from average  interest-earning assets and the
resultant yields, reported on a taxable-equivalent basis, as well as the average
interest-bearing liabilities,  expressed  both  in dollars  and  rates.  Average
balances  are  derived  from  weekly  balances  and  the  yields  and  costs are
established by dividing income or expense by the average balance of the asset or
liability. Income  and  yield  on interest-earning  assets  include  amounts  to
convert  tax-exempt  income  to  a  taxable-equivalent  basis,  assuming  a  34%
effective federal income tax rate.

    The  following table  presents the  effects of  changes in  volume, rate and
rate/volume on  interest income  and interest  expense for  major categories  of
interest-earning  assets and interest-bearing  liabilities. Nonaccrual loans are
included in assets,  thereby reducing yields  (see "Nonperforming Assets").  The
allocation  of the rate/volume variance has been made pro-rata on the percentage
that volume and rate variances produce in each category.

PROVISION FOR LOAN LOSSES
 
    The  provision for loan losses for the  three months ended March 31, 1996 of
$290 thousand reflects an  increase of $209 thousand  or 258.0% compared to  $81
thousand for the three months ended March 31, 1995.
 
    The  provision for loan losses for the year ended December 31, 1995 was $2.4
million an increase of $236 thousand or  10.8% from the year ended December  31,
1994. The provision for loan losses for the year ended December 31, 1994 of $2.2
million  reflects  a decrease  of $98  thousand  or 4.3%  from the  $2.3 million
provision for loan losses  for the year ended  December 31,1993. Provisions  for
loan losses are charged to earnings to bring the total allowance for loan losses
to  a  level  deemed  appropriate  by  management  based  upon  such  factors as
historical experience, the volume and type  of lending conducted by First  State
Bank,  the  amount  of  nonperforming  assets,  regulatory  policies,  generally
accepted accounting  principles, general  economic conditions,  particularly  as
they relate to First State Bank's lending area, and other factors related to the
collectibility  of First  State Bank's loan  portfolio. See  "Allowance for Loan
Losses."
 
    In January 1995, First State Bank 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". In management's opinion, the  adoption
of Statement 114 and Statement 118 did not have a material effect on First State
Bank's results of operations.
 
NONINTEREST INCOME
 
    Noninterest  income  for  the three  months  ended  March 31,  1996  of $338
thousand decreased $36 thousand or 9.6% compared to $374 thousand for the  three
months ended March 31, 1995.
 
                                      F-49
<PAGE>
    Noninterest  income of  $1.4 million  for the  year ended  December 31, 1995
increased $101 thousand or  7.8% compared to the  year ended December 31,  1994,
and  noninterest income  of $1.3  million for the  year ended  December 31, 1994
decreased $25  thousand or  1.9% compared  to $1.3  million for  the year  ended
December 31, 1993.
 
    First  State Bank offers  trust services, but does  not actively pursue this
type of business.  Trust service  fees were $24  thousand, $37  thousand and  $3
thousand for the years ended December 31, 1995, 1994 and 1993, respectively. The
book  value  of assets  managed  at December  31,  1995 was  approximately $11.5
million. Assets held by the trust department of First State Bank in fiduciary or
agency capacities are not assets of First State Bank and are not included in the
balance sheet.
 
    A detailed summary of  noninterest income for the  three months ended  March
31,  1996 and 1995 and during the last three years is presented in the following

NONINTEREST EXPENSE
 
    Noninterest expense  for the  three  months ended  March  31, 1996  of  $1.8
million  increased $295  thousand or  20.1% compared  to the  three months ended
March 31, 1995  or $1.5  million. The increase  in noninterest  expense for  the
three  months ended March  31, 1996 resulted  primarily from the  cost to settle
litigation and  other  costs associated  with  disposing of  other  real  estate
recorded  in the three months ended March 31, 1996. These increases were offset,
in part, by the decrease in FDIC insurance.
 
    Noninterest expense of  $6.3 million for  the year ended  December 31,  1995
increased  $122 thousand or 2.0%  compared to the year  ended December 31, 1994,
and noninterest expense  of $6.1  million for  the year  ended December  31,1994
decreased  $1.2 million or 16.3%  compared with $7.3 million  for the year ended
December 31, 1993.
 
    The largest category  of noninterest  expense, Total  Salaries and  Employee
Benefits  ("Personnel"), of  $2.8 million for  the year ended  December 31, 1995
increased $262  thousand or  10.2%  compared to  year  ended December  31,  1994
levels.  Personnel expenses of $2.6 million for the year ended December 31, 1994
increased $224 thousand or 9.6% compared to year ended December 31, 1993  levels
of  $2.3 million.  Personnel expense increased  primarily due to  an increase in
compensation levels.
 
    Occupancy expense of  $568 thousand  for the  year ended  December 31,  1995
increased  $13 thousand or 2.3% compared to the year ended December 31,1994, and
occupancy expense  of  $555  thousand  for the  year  ended  December  31,  1994
decreased  $85  thousand or  13.3% when  compared to  occupancy expense  of $640
thousand for the year ended December 31, 1993.
 
    Equipment expense was $341 thousand, $278 thousand and $261 thousand for the
years ended December 31, 1995, 1994 and 1993, respectively.
 
    Other noninterest expense of  $2.4 million for the  year ended December  31,
1995  decreased $114 thousand  or 4.5% compared  to the year  ended December 31,
1994 and other noninterest expense of  $2.5 million for the year ended  December
31, 1994 decreased $1.5 million or 36.8% when compared
 
                                      F-50
<PAGE>
with  the $4.0  million for the  year ended  December 31, 1993.  The increase in
other noninterest  expense  in 1995  resulted  from  an increase  in  legal  and
professional,  caused primarily from audit fees  incurred in 1995, and increases
in stationery, supplies and postage, all of which were offset by a reduction  in
FDIC  insurance premiums. The  principal factor attributable  to the decrease in
other noninterest expense for  the year ended  December 31, 1994  was a cost  to
settle  litigation which was recorded in 1993 and is included in other losses in
the detailed summary. In 1993, First State Bank settled a lender liability claim
by a former borrower.
 
    A detailed summary of noninterest expense  for the three months ended  March
31,  1996 and 1995 and during the last three years is presented in the following

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
    In December 1990, the Financial  Accounting Standards Board ("FASB")  issued
Statement   of  Financial  Accounting  Standards   No.  106  ("Statement  106"),
"Employers' Accounting for Postretirement  Benefits Other Than Pensions",  which
is  effective for fiscal years beginning  after December 15, 1992. Statement 106
requires  companies  that  have  postretirement  benefit  plans  to  accrue  the
estimated  cost of  providing those benefits  to an employee  and the employee's
beneficiaries  and  covered  dependents.  First  State  Bank  does  not  provide
postretirement  benefits other than nonqualified deferred compensation plans for
the benefit of the President and two other former officers of First State Bank.

INCOME TAX
 
    Income tax expense  amounted to  $914 thousand  for the  three months  ended
March  31, 1996 compared  to $1.1 million  for the three  months ended March 31,
1995. The decrease in income  tax expense for the  three months ended March  31,
1996  is due primarily  to a decreased  level of pretax  income during the three
months ended March 31, 1996.
 
    Income tax expense amounted to $3.4 million for the year ended December  31,
1995  compared to $3.2 million for the year ended December 31, 1994. Tax expense
varies from one  year to the  next with changes  in the level  of income  before
taxes, changes in the amount of tax-exempt interest income, and the relationship
of these changes to each other.
 
    First State Bank's effective tax rate for 1995 was 28.4% compared with 26.5%
in  1994. Income tax expense differs from the amount computed at statutory rates
primarily due  to tax-exempt  interest from  certain investment  securities  and
loans.
 
    Effective  January 1, 1993, First State  Bank adopted Statement of Financial
Accounting Standards No. 109 ("Statement  109"), "Accounting for Income  Taxes".
Through  December 31,  1992, First State  Bank accounted for  income taxes under
Accounting Principles Board Opinion No. 11 ("APB 11"). Statement 109 has changed
First State  Bank's method  of accounting  for income  taxes from  the  deferred
method  required  under APB  11 to  the  asset and  liability method.  Under the
deferred method, annual  income tax  expense is matched  with pretax  accounting
income  by providing deferred taxes at  current tax rates for timing differences
between the  determination  of  net  income  for  financial  reporting  and  tax
purposes.  The  objective of  the  asset and  liability  method is  to establish
deferred tax assets and liabilities for the recognition of future deductions  or
taxable  amounts. Deferred tax expense  or benefit is recognized  as a result of
the change in the asset or liability during the year.
 
NET INCOME
 
    Net income was $8.6  million, $8.8 million, and  $8.1 million for the  years
ended December 31, 1995, 1994, and 1993, respectively.
 
                        ANALYSIS OF FINANCIAL CONDITION
 
BALANCE SHEET COMPOSITION
 
    The  average assets and liabilities of First State Bank have remained stable
over the last  three years.  Average interest-earning assets  of $383.1  million
declined  $2.1 million or 0.6% for the  year ended December 31, 1995 compared to
the year  ended December  31, 1994.  Average interest-earning  assets of  $385.3
million  increased $8.0  million or  2.1% for the  year ended  December 31, 1994

CASH AND DUE FROM BANKS
 
    First  State Bank  offers a  broad range  of commercial  banking services to
individuals and businesses. The amount  of cash and due  from banks held on  any
one  day is significantly influenced by changes  in cash items in the process of
collection. At December  31, 1995, cash  and due from  banks was $16.3  million,
$1.7 million less than at December 31, 1994.
 
INVESTMENT SECURITIES
 
    Investment securities consist of two categories: Available for Sale and Held
to  Maturity. Securities  classified as  Held to  Maturity are  those securities
First State Bank has both  the positive intent and  ability to hold to  maturity
and  are carried at amortized cost.  Securities classified as Available for Sale
are those securities which  First State Bank intends  to hold for an  indefinite
period  of time but not necessarily to maturity. These securities may be sold as
part of  asset/liability  management strategy,  or  in response  to  significant
movements in interest rates, liquidity needs, regulatory capital considerations,
and  other similar factors.  These securities are  carried at fair  value in the
accompanying balance sheet. The percentage of the investment portfolio allocated
to Available for Sale and Held to Maturity was 14.1% and 85.9%, respectively  at
December  31, 1995 compared  with 18.5% and 81.5%,  respectively at December 31,
1994.

    At  December 31,  1995, U.S.  Government Agency  securities with  a carrying
value of approximately  $11.4 million contained  interest features which  adjust
according  to  various dual  indices and/or  which could  adjust to  zero. These
features relate only to  the interest payments and  do not affect the  principal
amount  due.  At  December  31,  1995,  the  weighted  average  coupon  of these
securities equalled  3.00%. One  issue with  a book  value of  $3.5 million  has
adjusted  to  zero percent  and will  mature  in May  1996. The  following table
presents the  maturities, amortized  cost  and estimated  market value  of  such

LOANS
 
    First State  Bank closely  monitors the  markets in  which it  conducts  its
lending.  A  certain degree  of risk  is  inherent in  the extension  of credit.
Management has instituted credit  policies designed to  monitor and control  the
level  of losses and nonperforming assets.  These policies require evaluation of
new credit  requests and  continuing  review of  existing credits  to  identify,
monitor and quantify any evidence of deterioration of quality or potential loss.
 
    First  State Bank attempts to diversify risk with the objective of achieving
optimum rates of return while minimizing losses for the benefit of  stockholders
and  protection of depositors. Diversification of  the loan portfolio by type of
loan, industry concentration and type of  borrower also tends to reduce risk  by
minimizing the adverse impact of any single event or set of occurrences.
 
    Total  loans at December 31,  1995 decreased $5.9 million  or 3.0% to $188.4
million compared to the  year-end balance at December  31, 1994. Total loans  at
December  31, 1994 of $194.3 million decreased $547 thousand or 0.3% compared to
the year-end  balance of  $194.9 million  at December  31, 1993.  The  principal
reason  for  the decrease  in total  loans  at year-end  1995 was  reductions in
agricultural and agricultural mortgage loans outstanding.
 
    Real estate loans, including construction, commercial mortgage, agricultural
mortgage and 1-4 family mortgage, continue to represent the largest component of
First State Bank's  loan portfolio. The  percent of real  estate loans to  total
loans  was  56.2%,  53.2%  and  53.0%, at  December  31,  1995,  1994  and 1993,
respectively.
 
    The  decline  in  agricultural  and  agricultural  mortgage  loans  resulted
primarily  from  reduced  borrowing  by  certain  customers  and  several  large
borrowers who discontinued farming and paid off their loans. This was offset  by
increases  in other lines which are normally paid down at this time of the year.

</TABLE>
 
    As  shown in  the preceding  table, loans  maturing within  one year totaled
$94.6 million or 50.2% of total loans at December 31, 1995. First State Bank may
renew or extend a loan on maturity based on
 
                                      F-58
<PAGE>
management's assessment  of  individual loans.  Extension  or renewal  of  loans
without  reduction  of  principal  for more  than  one  twelve-month  period are
generally avoided, unless  loans are fully  secured, or are  revolving lines  of
credit subject to annual analysis and renewal.
 
NONPERFORMING ASSETS
 
    Nonperforming  assets  consist  of  nonaccrual loans,  loans  for  which the
interest rate has been renegotiated  below originally contracted rates and  real
estate  or other assets that have been  acquired in partial or full satisfaction
of loan obligations.
 
    First State Bank's policy generally is to place a loan on nonaccrual  status
when  payment of  principal or  interest is contractually  past due  90 days, or
earlier when concern exists as to ultimate collection of principal and interest.
At the time a loan is  placed on nonaccrual status, interest previously  accrued
but  uncollected is  reversed and charged  against current income.  At March 31,
1996, three of the loan relationships on nonaccrual status totaling $2.0 million
had balances in  excess of $100  thousand. At  December 31, 1995,  three of  the
loans  on nonaccrual status totaling approximately  $1.8 million had balances in
excess of $100 thousand.
 
    Loans which are contractually past due 90 days or more, which are both  well
secured  or  guaranteed  by financially  responsible  third parties  and  in the
process of collection, generally are not placed on nonaccrual status. The amount
of such loans past due 90 days or more at March 31, 1996 and for the years ended
December 31, 1995, 1994 and 1993  that are not classified as nonaccrual  totaled
$1.8  million,  $4.9  million,  $3.2  million  and  $3.4  million, respectively.
Included in this classification at December 31, 1995 were agricultural loans  of
$2.4  million which represent carryovers  from the 1995 crop  year and for which
borrowers are awaiting disaster payments and/or insurance proceeds.
 
    Nonperforming assets  of $3.2  million  at December  31, 1995  increased  $1
thousand compared to December 31, 1994 levels of $3.2 million and decreased $475
thousand  or 13.1% for the year ended December 31, 1994 compared to December 31,
1993 levels of $3.6 million.
 
    First State  Bank's classification  of  nonperforming loans  includes  those
loans  for which management  believes collection is  doubtful. Management is not
aware  of  any  specific  borrower  relationships  that  are  not  reported   as
nonperforming  where management  has serious  doubts as  to the  ability of such
borrowers to comply  with the  present loan  repayment terms  which would  cause
nonperforming assets to increase materially.
 
    An  analysis of the components of nonperforming assets at March 31, 1996 and
at the end of each of the last five years is presented in the following table:

accordance with their original contract  terms was approximately $531  thousand,
$820 thousand and $232 thousand, respectively.
 
ALLOWANCE FOR LOAN LOSSES
 
    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 experience, 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. 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. The allowance for
loan losses at December 31, 1995 was $4.2 million, which represents an  increase
of  $281  thousand or  7.2%  as compared  to the  allowance  for loan  losses at
December 31, 1994.  Management believes that  the allowance for  loan losses  at
December  31, 1995 adequately reflects the risks in the loan portfolio. However,
various regulatory agencies, as an  integral part of their examination  process,
periodically  review First State Bank's allowance for loan losses. Such agencies
may require First State  Bank to recognize additions  to the allowance based  on
their  judgments  of  information  available  to  them  at  the  time  of  their
examination.
 
    As a  result  of criticisms  reflected  in the  October  4, 1993  Report  of
Examination  by the Texas  Department of Banking,  a Memorandum of Understanding
(the "Memorandum") was  entered into  between the  Board of  Directors of  First
State  Bank and  the Banking  Commissioner of  Texas on  December 14,  1993. The
Memorandum required  that First  State Bank,  among other  provisions,  increase
Board  of Directors supervision  over loan activities,  revise the existing loan
policy, increase the  allowance for  loan losses and  reduce criticized  assets.
Additionally, First State Bank's Board of Directors is required to submit to the
Commissioner  and Regional Director of the FDIC  a written report of the actions
taken to comply with the Memorandum. Management has made efforts to comply  with
the requirements of the Memorandum.

    Mexico  is a  part of the  trade territory  of First State  Bank and foreign
deposits from  Mexican sources  have  traditionally been  a source  of  funding.
Although  First  State Bank  experienced  a short  term  negative impact  on its
Mexican deposits due to the recent  devaluation of the peso, First State  Bank's
Mexican deposit levels have since recovered.

LIQUIDITY
 
    Liquidity management  assures  that adequate  funds  are available  to  meet
deposit   withdrawals,  loan  demand   and  maturing  liabilities.  Insufficient
liquidity can  result  in  higher  costs of  obtaining  funds,  while  excessive
liquidity  can  lead to  a  decline in  earnings due  to  the cost  of foregoing
alternative investments.  The ability  to renew  or acquire  additional  deposit
liabilities is a major source of liquidity. First State Bank's principal sources
of  funds are primarily within the local markets of First State Bank and consist
of deposits, interest and principal payments on loans and investment securities.
 
    Asset liquidity is provided by cash and assets which are readily marketable,
or which can be pledged, or which will mature in the near future. These  include
cash,  federal funds sold and U.S. Government-backed securities. At December 31,
1995,  First   State   Bank's   liquidity   ratio,   defined   as   cash,   U.S.
Government-backed securities, and federal funds sold as a percentage of deposits
was 48.1% compared to 45.2% at December 31, 1994.
 
    Liability   liquidity  is  provided  by  access  to  core  funding  sources,
principally various customers' interest-bearing and noninterest-bearing  deposit
accounts in the First State Bank's trade area.

    During  1995, funds for  $34.3 million of investment  purchases and the $2.1
million net  decrease in  deposits  came from  various sources,  including  $3.4
million  net repayments on loans, $47.8 million proceeds from maturing or called
securities and $8.6 million of net income.
 
    The Federal Deposit  Insurance Corporation Act  of 1991 ("FDICIA")  requires
that  federal bank regulatory  authorities take "prompt  corrective action" with
respect to  any depository  institution which  does not  meet specified  minimum
capital  requirements. The applicable regulations  establish five capital levels
which require or permit the  Federal Deposit Insurance Corporation (the  "FDIC")
and  other  regulatory  authorities  to take  supervisory  action.  The relevant
classifications range from "well  capitalized" to "critically capitalized."  The
classifications   are  generally   determined  by   applicable  ratios   of  the
institution, including Tier I capital to risk-weighted assets, total capital  to
risk-weighted  assets and leverage  ratios. Based on  First State Bank's capital
ratios  at  December  31,  1995,  First  State  Bank  was  classified  as  "well
capitalized"  under the  applicable regulations. As  a result,  First State Bank
does not believe that the prompt corrective action regulations have any material
effect on its activities or operations.
 
    The funds management policy of First  State Bank is to maintain a  liability
sensitive  position. Changes in net interest income occur when interest rates on
loans and investments change in a different time period from that of changes  in
interest  rates on liabilities,  or when the mix  and volume of interest-earning
assets and interest-bearing  liabilities change. The  interest rate  sensitivity
gap represents the dollar amount of difference between rate sensitive assets and
rate  sensitive liabilities within a  given time period ("GAP").  A GAP ratio is
determined by dividing rate  sensitive assets by  rate sensitive liabilities.  A
ratio of 1.0 indicates a perfectly matched position, in which case the effect on
net interest income due to interest rate movements would be zero.
 
    Rate  sensitive liabilities maturing within one year exceeded rate sensitive
assets with comparable maturities at December 31, 1995 by $83.3 million.

EFFECTS OF INFLATION
 
    Financial institutions  are  impacted  differently  by  inflation  than  are
industrial  companies.  While industrial  and manufacturing  companies generally
have  significant  investments  in  inventories  and  fixed  assets,   financial
institutions  ordinarily do  not have such  investments. As  a result, financial
institutions are generally  in a  better position than  industrial companies  to
respond  to inflationary trends by monitoring  the spread between interest costs
and yields through adjustments  to maturities and interest  rates of assets  and
liabilities.  In addition,  inflation tends  to increase  demand for  loans from
financial institutions as  industrial companies attempt  to maintain a  constant
level  of goods  in inventory  and assets. As  consumers of  goods and services,
financial institutions are affected by inflation as prices increase, causing  an
increase  in costs of salaries, employee benefits, occupancy expense and similar
items.
 
CAPITAL RESOURCES
 
    Stockholders' equity of $59.4  million at December 31,  1995 reflects a  net
increase  of  $4.1 million  or 7.5%  compared to  stockholders' equity  of $55.3
million at December  31,1994. This  net increase was  primarily attributable  to
earnings  for 1995  of $8.6  million. The  net increase  in stockholders' equity
reflects dividends paid on common stock of $5.0 million in 1995.

    The risk-based capital standards as established  by the FDIC apply to  First
State  Bank. The  numerator of the  risk-based capital ratio  for banks includes
Tier I  capital,  consisting  of  common  stockholders'  equity  and  qualifying
cumulative  and noncumulative  perpetual preferred  stock; and  Tier II capital,
consisting of  other  preferred stock,  reserve  for possible  loan  losses  and
certain  subordinated and term-debt securities.  Beginning on December 31, 1993,
goodwill is deducted from Tier I capital. At no time is Tier II capital  allowed
to exceed Tier I capital in the calculation of total capital. The denominator or
asset  portion of  the risk-based  capital ratio  aggregates generic  classes of
balance sheet and  off-balance sheet  exposures, each  weighted by  one of  four
factors,  ranging from 0%  to 100%, based  on the relative  risk of the exposure
class.
 
    Ratio targets are set for both Tier I and Total Capital (Tier I plus Tier II
capital). The minimum level of  Tier I capital to total  assets is 4.0% and  the
minimum  Total Capital  ratio is  8.0%. The FDIC  has guidelines  for a leverage
capital ratio that is an additional evaluation of capital adequacy of banks. The
leverage ratio is defined to be First State Bank's Tier I capital divided by its
risk  adjusted  total  assets.  An  insured  depository  institution  is   "well
capitalized"  for purposes  of FDICIA if  its Total Risk-Based  Capital Ratio is
equal to or greater than 10.0%, and Tier I Risk-Based Capital Ratio is equal  to
or  grater than 6.0%, and  Tier I Leverage Capital Ratio  is equal to or greater
than 5.0%. Based on capital ratios, First State Bank is within the definition of
"well capitalized" for FDIC purposes at December 31, 1995.
 
    First State Bank's Tier I Risk-Based Capital Ratio was approximately  18.47%
and 17.99% at December 31, 1995 and 1994, respectively. First State Bank's Total
Risk-Based  Capital Ratio  was approximately 19.78%  and 19.26%  at December 31,
1995 and 1994, respectively.  First State Bank's Tier  I Leverage Capital  Ratio
was approximately 14.88% and 13.98% at December 31, 1995 and 1994, respectively.

CURRENT ACCOUNTING ISSUES
 
    Effective January 1, 1995,  First State Bank adopted  Statement 114 and  the
amendment  thereof, Statement  118. 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
 
                                      F-67
<PAGE>
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 Statement 114, First State Bank makes an assessment for
impairment when and while such loans are  on nonaccrual status 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 First
State Bank using discounted  cash flows, except when  it is determined that  the
sole  source of repayment  for the loan  is the operation  or liquidation of the
underlying collateral. In such case, the  current 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.
 
    In management's opinion, the adoption of Statement 114 and Statement 118 did
not have a material effect on First State Bank's results of operations.
 
    In October 1995, the FASB issued Statement of Financial Accounting Standards
No.  123 ("Statement 123"), "Accounting for Stock-Based Compensation." Statement
123 establishes  financial accounting  and reporting  standards for  stock-based
employee compensation plans.
 
    Statement  123 encourages entities  to adopt a "fair  value" based method of
accounting for stock-based compensation plans which requires an estimate of  the
fair  value of stock options or  other equity instruments which employees become
entitled to  when  they  have  rendered requisite  service  or  satisfied  other
conditions  necessary  to  earn  the  right  to  benefit  from  the instruments.
Compensation cost is  then determined based  on the fair  value estimate and  is
recognized  over  the  service  period, which  is  usually  the  vesting period.
Statement 123  also requires  that an  employer's financial  statements  include
certain   disclosures  about  stock-based   employee  compensation  arrangements
regardless of the method used to account for them.
 
    The accounting requirements of Statement 123 are effective for  transactions
entered into in fiscal years that begin after December 15, 1995. In management's
opinion, implementation of Statement 123 should have no material effect on First
State Bank's financial statements.

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
 
(1)   BASIS OF PRESENTATION
    The accompanying  unaudited  financial  information  does  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 information furnished reflects 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.
 
(2)   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 effect 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.

The Board of Directors
First State Bank & Trust Co.:
 
    We  have audited the accompanying balance sheets of First State Bank & Trust
Co. (the "Bank") as of December 31, 1995 and 1994, and the related statements of
earnings, changes in stockholders' equity and  cash flows for each of the  years
in the three-year period ended December 31, 1995. These financial statements are
the responsibility of the Bank's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all material respects, the financial position of First State Bank & Trust Co.
as of December 31, 1995 and 1994, and the results of its operations and its cash
flows for the each of the years in the three-year period ended December 31, 1995
in conformity with generally accepted accounting principles.
 
    As discussed in  note 1 to  the financial statements,  the Bank changed  its
method  of accounting for investment securities  in 1994 to adopt the provisions
of Statement of Financial Accounting Standards No. 115, "Accounting for  Certain
Investments in Debt and Equity Securities."

                        DECEMBER 31, 1995, 1994 AND 1993
 
(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    The  accounting  and reporting  policies of  the  Bank conform  to generally
accepted accounting principles  and to prevailing  practices within the  banking
industry. A summary of the more significant accounting policies follows:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported amounts  of  assets and  liabilities and
disclosure of contingent  assets and liabilities  at the date  of the  financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
    For purposes of reporting  cash flows, cash and  due from banks and  federal
funds  sold are considered to be  cash equivalents. Federal funds sold generally
have one-day maturities.
 
TRUST ASSETS
 
    Assets held by the  trust department in fiduciary  or agency capacities  are
not  assets of the Bank and are not included in the balance sheets. Trust assets
at December  31, 1995  and 1994  are approximately  $11,542,000 and  $11,400,000
respectively.
 
INVESTMENT SECURITIES
 
    In  May  1993,  the  Financial Accounting  Standards  Board  ("FASB") issued
Statement  of  Financial  Accounting   Standards  No.  115  ("Statement   115"),
"Accounting  for Certain Investments  in Debt and  Equity Securities." Statement
115 establishes standards of financial accounting and reporting for  investments
in  equity securities that  have a readily  determinable fair value  and for all
investments in debt 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 balance sheet 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 balance sheet with unrealized holding gains and losses included  in
earnings.  Investments  not  classified  as held  to  maturity  nor  trading are
classified as available for sale and measured at fair value in the balance sheet
with unrealized  holding  gains and  losses,  net of  applicable  income  taxes,
reported in a separate component of stockholders' equity until realized.
 
    Effective  January 1,  1994, the  Bank adopted  Statement 115,  which had no
impact on  the Bank's  income statement  as all  securities were  classified  as
either  held  to  maturity  or available  for  sale.  Accounting  for securities
classified as held  to maturity will  continue on the  basis of amortized  cost.
Securities  classified as  available for sale  will be measured  at market value
with the  net  unrealized  holding  gains and  losses  reported  in  a  separate
component  of  stockholders'  equity  until  realized.  Purchases  of investment
securities are classified as available for sale  or held to maturity at time  of
purchase as determined by management.
 
    Premiums  and  discounts are  amortized and  accreted  using a  method which
approximates level  yield. Gains  and losses  on available  for sale  investment
securities  sold are recognized in  operations at the time  of sale based on the
specific identification method. Security purchases and sales are recorded on the
trade date.

(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
LOANS
 
    Management continually reviews the loan  portfolio to identify loans  which,
with respect to principal or interest, have or may become collection problems. 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 on management's  assessment of  the
ultimate collectibility of principal.
 
    Unearned  interest on  installment loans  is recognized  as income  over the
terms of the related loans on a basis which results in approximately level rates
of return over the terms of the loans.
 
    In May 1993, the FASB issued Statement of Financial Accounting Standards No.
114 ("Statement 114"), "Accounting by Creditors for Impairment of a Loan," which
addresses the  accounting  by creditors  for  impairment of  certain  loans,  as
defined.  In October 1994,  Statement 114 was amended  by Statement of Financial
Accounting Standards No. 118, "Accounting by Creditors for Impairment of a Loan,
Income Recognition and Disclosures."  Implementation of these pronouncements  in
the first quarter of 1995 did not have a material effect on the Bank's financial
statements.
 
ALLOWANCE FOR LOAN LOSSES
 
    The  allowance for loan losses  is established by a  charge to operations as
deemed necessary by management to maintain  the allowance for loan losses at  an
amount considered adequate to absorb known or possible loan losses in the Bank's
loan  portfolio. The provision is determined based on management's evaluation of
the loan  portfolio,  giving  consideration  to  existing  economic  conditions,
changes  in the loan portfolio, historical  loan loss factors and other relevant
information. Management believes that the allowance for loan losses is adequate.
 
    Loans are  charged against  the allowance  for loan  losses when  management
believes  the  collection  of  principal  is  unlikely.  Recoveries  of  amounts
previously charged off are credited to the allowance.
 
BANK PREMISES AND EQUIPMENT
 
    Bank  premises  and  equipment  are  recorded  at  cost.  Expenditures   for
improvements  are capitalized. Repairs  and maintenance which  do not extend the
life of  bank  premises  and  equipment are  charged  to  expense  as  incurred.
Depreciation and amortization are calculated using the straight-line method over
the  estimated  useful lives  of the  assets.  Any gain  or loss  resulting from
disposition of premises and equipment is reflected in earnings.
 
OTHER REAL ESTATE OWNED
 
    Other real estate owned is recorded at fair value at the date of foreclosure
which is subsequently considered cost. At subsequent dates, other real estate is
carried at the lower of  fair value less estimated costs  to sell or cost.  Fair
values are determined generally by reference to appraisals. Rental income earned
and  expenses incurred  related to real  estate owned are  recognized during the
period earned or incurred and are  included in noninterest expense at their  net
amount.
 
FEDERAL INCOME TAXES
 
    Deferred  tax assets and liabilities are recognized for estimated future tax
consequences  attributable  to  differences  between  the  financial   statement
carrying  amounts of  existing assets and  liabilities and  their respective tax
bases, and operating loss and tax credit carryforwards. Deferred tax assets  and
liabilities

(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
are measured using tax rates expected to apply to taxable income in the years in
which  those  temporary differences  are expected  to  be recovered  or settled.
Deferred tax expense or benefit is recognized  as a result of the change in  the
asset or liability during the year.
 
(2)   RESERVE REQUIREMENTS
    The  Bank is required to maintain certain  daily reserve balances on hand or
on deposit with  the Federal  Reserve Bank  in accordance  with Federal  Reserve
Board requirements. These deposits are noninterest bearing and not available for
investment  purposes. Cash and  due from bank  balances maintained in accordance
with such requirements at December 31, 1995 was approximately $5,611,000.

    The amortized cost and estimated market value, which is the carrying  value,
of  investment securities available  for sale at December  31, 1995 and December

    The majority of the Bank's loans are to companies and individuals which  are
headquartered or are employed in the Rio Grande Valley, but may conduct business
on  a statewide, national, or international  scale. Repayment of those loans may
be dependent on the economy  in the Rio Grande Valley  which is impacted by  the
economic situation in Mexico and surrounding areas.
 
    All loans to officers, directors and stockholders of the Bank and associates
of  such persons are, in the opinion  of management, made in the ordinary course
of business  on  substantially the  same  terms, including  interest  rates  and
collateral, as those prevailing at the time for comparable loans of like quality
and risk of collectibility. The outstanding balance of total personal borrowings
of  executive officers and directors  of the Bank at  December 31, 1995 and 1994
were approximately $2,032,000 and $1,446,000, respectively.
 
    At December  31, 1995,  the Bank  had a  $1,736,000 recorded  investment  in
impaired loans, all of which are nonaccrual loans, for which there was a related
allowance  of $836,000. All loans considered impaired at December 31, 1995 had a
related allowance for loan  losses. The average level  of impaired loans  during
the  year ended  December 31,  1995 was  $2,536,000. The  Bank recorded interest
income of $41,500 on its impaired loans during the year ended December 31, 1995.
 
    Nonaccrual loans approximated $2,724,000 and $2,562,000 at December 31, 1995
and 1994,  respectively. If  interest on  these loans  had been  accrued at  the
original  contractual  rates,  interest  income  would  have  been  increased by
approximately $531,000, $820,000 and $232,000  for the years ended December  31,
1995,  1994 and 1993.  There were no renegotiated  loans outstanding at December
31, 1995, 1994 and 1993, respectively.
 
    In the normal course of business, the Bank enters into various  transactions
which,  in  accordance with  generally accepted  accounting principles,  are not
included  on  the  balance  sheets.  These  transactions  are  referred  to   as
"off-balance sheet commitments." The Bank 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.  The
Bank  minimizes its exposure to loss  under these commitments by subjecting them
to credit approval and monitoring procedures.

    Management  believes that  it is  more likely than  not that  the results of
future operations  will  generate  sufficient  taxable  income  to  realize  the
deferred tax assets.
 
(9)   EMPLOYEE BENEFITS
    The  Bank has three separate deferred  compensation plans for the benefit of
certain Bank employees. The plans provide for retirement benefits to be paid  to
the  specific employee  (or a designated  beneficiary or estate  if death occurs
prior to payment of  the full amount of  deferred compensation) on reaching  age
65.  One  plan  entered  into  on  December  10,  1963,  commenced  payments  of
approximately  $13,000  each  year  on  January  4,  1988,  continuing  annually
thereafter  through June 2003. A second plan, entered into on September 1, 1979,
provides for payments of approximately $13,000 each year which was scheduled  to
commence  on April  1, 1990, continuing  annually thereafter  through June 2005;
however, the employee elected to receive  an amount less than that provided  for
in  the  plan over  a  longer period  of  time. The  third  plan provides  for a
retirement  benefit   payable  of   $50,000  per   year  commencing   in   March

1999  and continuing  annually thereafter for  20 years. The  amounts charged to
compensation expense related to  the deferred compensation  plans for the  years
ended  December  31, 1995,  1994  and 1993  were  $15,300, $13,600  and $11,800,
respectively.
 
    The Bank owns and is the beneficiary of three life insurance policies on the
employees or former employees  covered by the  deferred compensation plans.  The
life  insurance policy face values are  amounts approximately equal to the total
benefits paid under the plans.
 
(10)  CONTINGENT LIABILITIES
    The Bank is involved in certain  claims and suits occurring in the  ordinary
course  of business.  Management believes that  the probable  resolution of such
claims and  suits will  not have  a  material adverse  affect on  the  financial
condition of the Bank.
 
(11)  FAIR VALUE OF FINANCIAL INSTRUMENTS
    The  estimated fair values at December  31, 1995 and methods and assumptions
used to determine the estimated fair values  are set forth below for the  Bank's
financial instruments:

CASH AND DUE FROM BANKS
 
    Carrying  value approximates  fair value  because of  the short  maturity of
these instruments and no anticipated credit concerns.
 
FEDERAL FUNDS SOLD
 
    Carrying value  approximates fair  value because  of the  short maturity  of
these instruments and no anticipated credit concerns.
 
INVESTMENT SECURITIES
 
    The  fair  values of  investment securities  are  estimated based  on quoted
market prices from investment dealers and companies.
 
NET LOANS
 
    The fair value of loans is estimated for segregated groupings of loans  with
similar  financial characteristics.  Loans are segregated  by type  and the fair
value of loans is estimated using current market rates for the type of loan.
 
DEPOSITS
 
    The fair value of  deposits with short-term or  no stated maturity, such  as
checking,  savings,  NOW accounts  and money  market accounts,  is equal  to the
amounts payable at December 31, 1995. The fair value of certificates of deposits
is based on the discounted value of contractual cash flows. The discount rate is
estimated using the rates  currently offered for  deposits of similar  remaining
maturities.

COMMITMENTS TO EXTEND CREDIT AND LETTERS OF CREDIT

(12)  REGULATORY SUPERVISION
    As a  result  of criticisms  reflected  in the  October  4, 1993  Report  of
Examination  by the Texas  Department of Banking,  a Memorandum of Understanding
(the "Memorandum") was entered into between  the Board of Directors of the  Bank
and  the  Banking Commissioner  of Texas  on December  14, 1993.  The Memorandum
required that  the Bank,  among  other provisions,  increase Board  of  Director
supervision  over loan activities, revise the existing loan policy, increase the
allowance for loan losses and reduce criticized assets. Additionally, the Bank's
Board of  Directors is  required  to submit  to  the Commissioner  and  Regional
Director  of the FDIC, a written report of  the actions taken to comply with the
Memorandum within fifteen days after the  end of each calendar quarter.  Failure
to  comply with  the requirements  of the Memorandum  could subject  the Bank to
additional action by bank regulatory authorities. Management has made efforts to
comply with  the requirements  of the  Memorandum and  believes such  additional
action will not be taken by regulatory authorities.
 
(13)  PENDING TRANSACTION
    On  January 9,  1996, a  definitive agreement  was signed  under which First
State Bank &  Trust Co. will  be purchased  by Texas State  Bank, the  principal
operating  subsidiary of Texas Regional Bancshares,  Inc. The agreement has been
approved by the Boards of Directors of First State Bank & Trust Co., Texas State
Bank and Texas  Regional Bancshares, Inc.  The sale  of the Bank  is subject  to
approval by the appropriate regulatory agencies and contingent upon, among other
things,  Texas Regional  Bancshares, Inc. having  successfully raised additional
capital to partially fund the transaction.

                                THE BORDER BANK
          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    The  following  discussion  provides  additional  information  regarding the
financial condition and the results of operations for Border Bank for the  three
months  ended March 31, 1996  and 1995 and for each  of the years ended December
31, 1995, 1994 and 1993. This discussion should be read in conjunction with  the
financial statements of Border Bank and the notes thereto appearing elsewhere in
this prospectus.
 
SELECTED FINANCIAL INFORMATION
 
    Net  income for the three  months ended March 31,  1996 was $591 thousand or
$2.96 per share  compared to  $603 thousand  or $3.02  per share  for the  three
months ended March 31, 1995.
 
    Net income for the year ended December 31, 1995 was $1.9 million, a decrease
of  19.0% compared to net income of $2.3 million for the year ended December 31,
1994. The earnings  per share  of $9.42  for the  year ended  December 31,  1995
decreased  $2.20 or 18.9% compared to earnings  per share of $11.62 for the year
ended December 31, 1994.
 
    Return on average assets for 1995 was 1.62%, compared to 1.98% for 1994  and
1.83%  for 1993.  Return on  average stockholders'  equity was  11.50% for 1995,
compared to 15.73% for 1994 and 15.79% for 1993.
 
    Earnings performance  for  the year  ended  December 31,  1995  reflected  a
decrease  in  net  interest income,  a  decrease  in noninterest  income  and an
increase in provision for loan losses.  The decrease in net interest income  for
1995 resulted primarily from an increase in interest expense.
 
                       ANALYSIS OF RESULTS OF OPERATIONS
 
NET INTEREST INCOME
 
    Taxable-equivalent net interest income was $1.4 million for the three months
ended  March 31, 1996 and 1995. The interest  rate margin of 5.00% for the three
months ended March 31, 1996 reflects a  decrease of 36 basis points compared  to
5.36%  for the three months  ended March 31, 1995.  The decrease in net interest
income resulted primarily from increased  volumes and rates on  interest-bearing
deposits offset by increased volumes of interest-earning assets.
 
    Taxable-equivalent  net interest income was $5.2  million for the year ended
December 31, 1995,  a decrease of  $529 thousand  or 9.2% compared  to the  year
ended  December  31, 1994  and taxable-equivalent  net  interest income  of $5.8
million for the  year ended  December 31, 1994  increased $52  thousand or  0.9%
compared to the year ended December 31, 1993.
 
    The  net yield on interest-earning assets, also referred to as interest rate
margin, represents  net  interest  income divided  by  average  interest-earning
assets.  The net interest rate  margin of 4.92% for  the year ended December 31,
1995 decreased 42 basis points compared to 5.34% for the year ended December 31,
1994. The decrease in net interest rate margin is due primarily to higher  rates
paid  on time deposits. The net interest rate margin for the year ended December
31, 1994 reflects  a decrease of  15 basis points  from the 5.49%  for the  year
ended December 31, 1993.
 
    Average  interest-earning  assets declined  $1.5 million  or 1.4%  to $106.5
million for the year ended December  31, 1995. The decrease in  interest-earning
assets  was consistent for all  categories of interest-earning assets, including
loans, investment securities  and federal funds  sold. Average  interest-earning
assets  increased $3.8  million or  3.7% to  $108.0 million  for the  year ended
December 31,  1994. The  increase in  average interest-earning  assets for  1994
resulted  primarily from  an increase in  investment securities  of $5.8 million
offset by declines in loans and federal funds sold.
 
    Average interest-earning assets comprised 91.6%  of average total assets  in
1995, compared to 92.0% in 1994 and 91.8% in 1993.
 
    Average  interest-bearing deposits  declined $3.0  million or  3.2% to $92.2
million for the year  ended December 31,  1995 compared to  an increase of  $2.2
million or 2.4% to $95.3 million for the year ended
 
                                      F-89
<PAGE>
December  31,  1994. These  changes in  the mix  of interest-earning  assets and
interest-bearing deposits  caused  the  ratio of  interest-bearing  deposits  to
interest-earning  assets to decline to 86.6% in  1995, compared to 88.2% in 1994
and 89.3% in 1993.
 
    Average noninterest-bearing deposits increased $180 thousand or 2.6% to $7.1
million in 1995 compared to an increase of $113 thousand or 1.7% to $6.9 million
in 1994.  The ratio  of average  noninterest-bearing deposits  to average  total
deposits was 7.2% for 1995, compared to 6.8% for each of 1994 and 1993.
 
    The  following table presents for the three  months ended March 31, 1996 and
1995, the total dollar amount  of interest income from average  interest-earning
assets  and resultant yields, reported on a taxable-equivalent basis, as well as
the interest-bearing liabilities, expressed both  in dollars and rates.  Average
balances  are  derived  from  weekly  balances  and  the  yields  and  costs are
established by dividing income or expense by the average balance of the asset or
liability. Income  and  yield  on interest-earning  assets  include  amounts  to
convert  tax-exempt  income  to  a  taxable-equivalent  basis,  assuming  a  34%
effective income tax rate.

  (1) For analytical purposes, income from tax-exempt assets, primarily 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).

      by state  and  local  governments  or authorities,  is  adjusted  by  an

    The following table  presents the  effects of  changes in  volume, rate  and
rate/volume  on interest  income and  interest expense  for major  categories of
interest-earning assets and interest-bearing  liabilities. Nonaccrual loans  are
included  in assets, thereby  reducing yields (see  "Nonperforming Assets"). The
allocation of the rate/volume variance has been made pro-rata on the  percentage
that volume and rate variances produce in each category.

  (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).
 
NET YIELD ON EARNING ASSETS
 
    The following table presents net interest income, average earning assets and
the  net yield by quarter for the three months ended March 31, 1996 and for each

PROVISION FOR LOAN LOSSES
 
    The provision for loan losses for the  three months ended March 31, 1996  of
$71  thousand reflects  an increase  of $19  thousand or  36.5% compared  to $52
thousand for the three months ended March 31, 1995.
 
                                      F-93
<PAGE>
    The provision for loan losses for the year ended December 31, 1995 was  $485
thousand,  an increase of $88 thousand or  22.2% from $397 thousand for the year
ended December  31, 1994.  The provision  for  loan losses  for the  year  ended
December  31, 1994 reflects an increase of  $132 thousand or 49.8% from the $265
thousand provision  for  loan  losses  for  the  year  ended  December  31,1993.
Provisions  for loan losses are charged to earnings to bring the total allowance
for loan losses  to a  level deemed appropriate  by management  based upon  such
factors  as historical experience,  the volume and type  of lending conducted by
Border Bank, the amount of nonperforming assets, regulatory policies,  generally
accepted  accounting  principles, general  economic conditions,  particularly as
they relate to  Border Bank's  lending area, and  other factors  related to  the
collectibility of Border Bank's loan portfolio. See "Allowance for Loan Losses."
 
    In  January  1995, Border  Bank  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". In management's opinion, the adoption
of Statement 114  and Statement 118  did not  have a material  effect on  Border
Bank's results of operations.
 
NONINTEREST INCOME
 
    Noninterest income for the three months ended March 31, 1996 of $94 thousand
increased  $19 thousand or 25.3%  compared to $75 thousand  for the three months
ended March 31, 1995.
 
    Noninterest income of  $316 thousand for  the year ended  December 31,  1995
decreased  $87 thousand or 21.6%  compared to the year  ended December 31, 1994,
and noninterest income  of $403 thousand  for the year  ended December 31,  1994
increased  $117 thousand or 40.9%  compared to $286 thousand  for the year ended
December 31,  1993. The  principal  factor affecting  the level  of  noninterest
income  in  1994 was  a  reimbursement to  Border Bank  of  $142 thousand  by an
insurance company in connection with the prior year settlement of a lawsuit (See
"Noninterest Expense") which was partially offset by a payment by Border Bank of
$48 thousand to resolve unrelated litigation.

31,  1996 and 1995 and during the last three years is presented in the following

NONINTEREST EXPENSE
 
    Noninterest expense of  $2.2 million for  the year ended  December 31,  1995
decreased $18 thousand or 0.8% compared to the year ended December 31, 1994, and
noninterest  expense  of  $2.2  million  for  the  year  ended  December 31,1994
decreased $296 thousand or 11.9% compared  with $2.5 million for the year  ended
December 31, 1993.
 
    The  largest category  of noninterest  expense, Total  Salaries and Employee
Benefits ("Personnel") of  $1.1 million  for the  year ended  December 31,  1995
decreased  $5 thousand or 0.5% compared to  year ended December 31, 1994 levels.
Personnel expense of $1.1 million for the year ended December 31, 1994 increased
$116 thousand or 12.3% compared to year  ended December 31, 1993 levels of  $945
thousand.  Personnel  expense increased  for the  year  ended December  31, 1994
primarily due to an increase in compensation levels.
 
                                      F-94
<PAGE>
    Occupancy expense of  $234 thousand  for the  year ended  December 31,  1995
increased  $6 thousand or 2.6% compared to  the year ended December 31,1994, and
occupancy expense  of  $228  thousand  for the  year  ended  December  31,  1994
increased  $57  thousand or  33.3% when  compared to  occupancy expense  of $171
thousand for the year ended  December 31, 1993. The  increases in 1995 and  1994
are primarily attributable to an expansion to Border Bank which began in 1994.
 
    Equipment expense was $148 thousand, $139 thousand and $144 thousand for the
years ended December 31, 1995, 1994 and 1993, respectively.
 
    Other  noninterest expense of $729 thousand  for the year ended December 31,
1995 decreased $15 thousand or 2.0% compared to the year ended December 31, 1994
and other noninterest expense of $744  thousand for the year ended December  31,
1994  decreased $474 thousand or  38.9% when compared with  the $1.2 million for
the year  ended December  31, 1993.  The principal  factor attributable  to  the
decrease in other noninterest expense for the year ended December 31, 1994 was a
cost  to settle  litigation which  was recorded  in 1993.  In 1993,  Border Bank
settled a lender liability claim by a former borrower.
 
    The  increase  in  legal  and  professional  fees  in  1995  was   primarily
attributable to audit fees incurred in 1995.

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS
 
    In  December 1990, the Financial  Accounting Standards Board ("FASB") issued
Statement  of  Financial  Accounting   Standards  No.  106  ("Statement   106"),
"Employers'  Accounting for Postretirement Benefits  Other Than Pensions", which
is effective for fiscal years beginning  after December 15, 1992. Statement  106
requires  companies  that  have  postretirement  benefit  plans  to  accrue  the
estimated cost of  providing those benefits  to an employee  and the  employee's
beneficiaries   and   covered   dependents.  Border   Bank   does   not  provide
postretirement benefits other than a nonqualified deferred compensation plan for
the benefit of a former President.
 
INCOME TAX
 
    Income tax expense  amounted to  $172 thousand  for the  three months  ended
March  31, 1996 compared to  $136 thousand for the  three months ended March 31,
1995. The increase in income  tax expense for the  three months ended March  31,
1996 is due primarily to an increased level of pretax income and decreased level
of tax-exempt interest.
 
    Income tax expense amounted to $381 thousand for the year ended December 31,
1995 compared to $604 thousand for the year ended December 31, 1994. Tax expense
varies  from one  year to the  next with changes  in the level  of income before
taxes, changes in the amount of tax-exempt interest income, and the relationship
of these changes to each other.
 
    Border Bank's effective tax rate for  1995 was 16.8% compared with 20.6%  in
1994.  Income tax  expense differs from  the amount computed  at statutory rates
primarily due to tax-exempt interest from certain investment securities.
 
    Effective January  1,  1993,  Border Bank  adopted  Statement  of  Financial
Accounting  Standards No. 109 ("Statement  109"), "Accounting for Income Taxes".
Through December  31,  1992,  Border  Bank  accounted  for  income  taxes  under
Accounting Principles Board Opinion No. 11 ("APB 11"). Statement 109 has changed
Border  Bank's method  of accounting for  income taxes from  the deferred method
required under APB  11 to  the asset and  liability method.  Under the  deferred
method,  annual income tax  expense is matched with  pretax accounting income by
providing deferred taxes at current tax rates for timing differences between the
determination of  net  income for  financial  reporting and  tax  purposes.  The
objective  of the asset and liability method is to establish deferred tax assets
and liabilities for  the recognition  of future deductions  or taxable  amounts.
Deferred  tax expense or benefit is recognized as  a result of the change in the
asset or liability during the year.
 
NET INCOME
 
    Net income was  $1.9 million, $2.3  million and $2.1  million for the  years
ended December 31, 1995, 1994 and 1993, respectively.
 
                        ANALYSIS OF FINANCIAL CONDITION
 
BALANCE SHEET COMPOSITION
 
    The  average assets and liabilities of Border Bank have remained stable over
the last three years. Average interest-earning assets of $106.5 million declined
$1.5 million or 1.4% for the year  ended December 31, 1995 compared to the  year
ended  December  31, 1994.  Average  interest-earning assets  of  $108.0 million
increased $3.8 million or 3.7% for the year ended December 31, 1994 compared  to
$104.2  million for the year  ended December 31, 1993.  Average loans to average
interest-earning assets was 43.6%  in 1995 and 1994  compared to 46.1% in  1993.
Average investment securities amounted to $55.6 million, $55.9 million and $50.1
million in 1995, 1994 and 1993, respectively.
 
    Average  interest-bearing deposits  declined $3.0  million or  3.2% to $92.2
million for the year  ended December 31, 1995  after increasing $2.2 million  or
2.4% to $95.3 million for the year ended December 31, 1994. The ratio of average
demand deposits to average total deposits for the years ended December 31, 1995,
1994 and 1993 was 7.2%, 6.8%, and 6.8%, respectively.

CASH AND DUE FROM BANKS
 
    Border  Bank  offers  a  broad  range  of  commercial  banking  services  to
individuals and businesses. The amount  of cash and due  from banks held on  any
one  day is  significantly influenced  by changes  in cash  items in  process of
collection. At December 31, 1995, cash and due from banks was $4.0 million, $0.9
million more than at December 31, 1994.
 
INVESTMENT SECURITIES
 
    Investment securities consist of two categories: Available for Sale and Held
to Maturity.  Securities classified  as Held  to Maturity  are those  securities
Border Bank has both the positive intent and ability to hold to maturity and are
carried at amortized cost. Securities classified as Available for Sale are those
securities  which Border Bank intends  to hold for an  indefinite period of time
but not  necessarily  to maturity.  These  securities may  be  sold as  part  of
asset/liability  management strategy, or in response to significant movements in
interest rates, liquidity  needs, regulatory capital  considerations, and  other
similar  factors. These securities are carried at fair value in the accompanying
balance sheet. The percentage of the investment portfolio allocated to Available

    At  December 31,  1995, U.S.  Government Agency  securities with  a carrying
value of approximately  $4.0 million  contained interest  features which  adjust
according  to  various dual  indices and/or  which could  adjust to  zero. These
features relate only to  the interest payments and  do not affect the  principal
amount  due.  At  December  31,  1995,  the  weighted  average  coupon  of these
securities equalled 2.76%.

LOANS
 
    Border Bank closely monitors the markets in which it conducts its lending. A
certain  degree of risk is  inherent in the extension  of credit. Management has
instituted credit policies designed to monitor  and control the level of  losses
and  nonperforming  assets.  These  policies require  evaluation  of  new credit
requests and continuing review of existing credits in order to identify, monitor
and quantify any evidence of deterioration of quality or potential loss.
 
    Border Bank  attempts to  diversify  risk with  the objective  of  achieving
optimum  rates of return while minimizing losses for the benefit of stockholders
and protection of depositors. Diversification of  the loan portfolio by type  of
loan,  industry concentration and type of borrower  also tends to reduce risk by
minimizing the adverse impact of any single event or set of occurrences.
 
    Total loans of $47.3 million for the year ended December 31, 1995  increased
$1.5 million or 3.2% compared to the year ended December 31,1994 levels of $45.9
million  and decreased $2.5 million or 5.2%  for the year ended December 31,1994
compared to levels of $48.4 million at December 31, 1993. The increase in  loans
outstanding at December 31, 1995 compared to December 31, 1994 was the result of
increases in real estate loans which were offset by small declines in commercial
and  consumer  loans. The  largest component  of the  portfolio continues  to be
commercial mortgages. At December 31,  1995, commercial mortgages totaled  $20.2
million  or 42.7% of the  total loan portfolio. At  December 31, 1994 commercial
mortgages were $15.9 million or 34.7% of the total loan portfolio.
 
    Border Bank has made  loans to individuals or  companies that are  residents
of,  or domiciled in,  Mexico. Such loans  may be secured  or unsecured. Secured
loans include  loans secured  by  deposits in  Border  Bank, real  estate  loans
secured  by properties located within the United States and loans on real estate
and equipment where the collateral is located in Mexico. Following is a  summary
of  loans to individuals and  companies that are residents  of, or domiciled in,
Mexico at March 31, 1996 and at the end of each of the last three years:

</TABLE>
 
    As  shown in  the preceding  table, loans  maturing within  one year totaled
$27.9 million or  59.0% of total  loans at  December 31, 1995.  Border Bank  may
renew  or  extend  a loan  upon  maturity  based on  management's  assessment of
individual loans. Extension or renewal  of loans without reduction of  principal
for  more than one  twelve-month period are generally  avoided, unless loans are
fully secured,  or are  revolving lines  of credit  subject to  at least  annual
analysis and renewal.
 
NONPERFORMING ASSETS
 
    Nonperforming  assets  consist  of  nonaccrual loans,  loans  for  which the
interest rate has been renegotiated  below originally contracted rates and  real
estate  or other assets that have been  acquired in partial or full satisfaction
of loan obligations.  At December 31,  1995, there were  twelve loans  totalling
$189 thousand on nonaccrual status, none of which had a balance greater than $40
thousand.
 
    Border  Bank's policy generally is to place a loan on nonaccrual status when
payment of principal or interest is  contractually past due 90 days, or  earlier
when  concern exists as to ultimate collection of principal and interest. At the
time a loan  is placed  on nonaccrual  status, interest  previously accrued  but
uncollected is reversed and charged against current income.
 
    Loans  which are contractually past due 90 days or more, which are both well
secured or  guaranteed  by financially  responsible  third parties  and  in  the
process of collection, generally are not placed on nonaccrual status. The amount
of  such  loans past  due  90 days  or  more for  the  years ended  December 31,
 
                                     F-103
<PAGE>
1995, 1994 and 1993 that are not classified as nonaccrual totaled $1.1  million,
$414  thousand, and $395 thousand, respectively. The increase for the year ended
December 31, 1995  as compared to  the year  ended December 31,  1994 is  partly
attributable  to two credits  totaling $491 thousand  included in that category,
which are secured by real estate and in the process of collection.
 
    Nonperforming assets of  $433 thousand  at December 31,  1995 decreased  $49
thousand  or 10.2%  compared to  December 31, 1994  levels of  $482 thousand and
decreased $317 thousand or 39.7% for  the year ended December 31, 1994  compared
to December 31, 1993 levels of $799 thousand.
 
    Border Bank's classification of nonperforming loans includes those loans for
which management believes collection is doubtful. Management is not aware of any
specific  borrower relationships  that are  not reported  as nonperforming where
management has serious doubts as to the ability of such borrowers to comply with
the present  loan repayment  terms  which would  cause nonperforming  assets  to
increase materially.
 
    An  analysis of the components of nonperforming assets at March 31, 1996 and
for the last five years is presented in the following table:

</TABLE>
 
    Interest income that would have been  recorded for the years ended  December
31,  1995 and 1994  on nonaccrual loans  had such loans  performed in accordance
with their  original  contract  terms  was approximately  $2  thousand  and  $34
thousand, respectively.
 
ALLOWANCE FOR LOAN LOSSES
 
    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 experience, 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. 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. The allowance for
loan losses at December 31, 1995 was $1.1 million, which represents an  increase
of  $199  thousand or  22.1% as  compared to  the allowance  for loan  losses at
December 31, 1994.  Management believes that  the allowance for  loan losses  at
December  31, 1995 adequately reflects the risks in the loan portfolio. However,
various regulatory agencies, as an  integral part of their examination  process,
 
                                     F-104
<PAGE>
periodically  review Border Bank's allowance for  loan losses. Such agencies may
require Border  Bank to  recognize additions  to the  allowance based  on  their
judgments of information available to them at the time of their examination.
 
    Management  of  Border Bank  does not  consider loans  to residents  of, and
companies domiciled in,  Mexico to present  an unusual risk.  Border Bank's  net
charge-offs   from  these  loans  has  not  been  significant  and  it  has  not
specifically allocated allowance for loan losses to these loans.
 
    As a  result  of  criticisms  reflected  in the  June  28,  1993  Report  of
Examination  by the Texas  Department of Banking,  a Memorandum of Understanding
(the "Memorandum") was  entered into between  the Board of  Directors of  Border
Bank  and the Banking Commissioner  of Texas on October  8, 1993. The Memorandum
required that Border Bank, among  other provisions, increase Board of  Directors
supervision  over loan activities, revise the existing loan policy, increase the
allowance for loan  losses and  reduce criticized  assets. Additionally,  Border
Bank's Board of Directors is required to submit to the Commissioner and Regional
Director  of the FDIC a  written report of the actions  taken to comply with the
Memorandum. Management has made efforts to  comply with the requirements of  the
Memorandum.

PREMISES AND EQUIPMENT
 
    Bank  premises and equipment  of $3.3 million  at December 31,1995 increased
$77 thousand or  2.4% compared to  $3.2 million  at December 31,  1994. The  net
increase  for the year ended December 31,  1995 is primarily attributable to the
completion of an expansion of Border Bank, which began in 1994, and the purchase
of additional land for future expansion.
 
DEPOSITS
 
    Total deposits of $102.0 million at December 31, 1995 increased $1.1 million
or 1.1%  compared to  December 31,  1994  levels and  total deposits  of  $100.9
million  for the year  ended December 31,  1994 increased $344  thousand or 0.3%
compared to December  31, 1993 levels  of $100.5 million.  The relatively  small
changes  in  deposits are  consistent in  all  categories of  deposits including
public funds and  reflect the  stable level of  deposits at  Border Bank.  Total
public  funds (including public funds demand deposits, public funds money market
and  NOW  accounts  and  public   funds  time  deposits)  were  $10.0   million,

$9.8   million  and  $10.6  million  at   December  31,  1995,  1994  and  1993,

    Based upon the  location of  Border Bank  with regard  to the  international
boundary  with Mexico, foreign  deposits from Mexican  sources represent a major
source of funding.  Although Border  Bank experienced  some short-term  negative
impact on its Mexican deposits due to the recent devaluation of the peso, Border
Bank's Mexican deposit levels have since recovered.

LIQUIDITY
 
    Liquidity management  assures  that adequate  funds  are available  to  meet
deposit   withdrawals,  loan  demand   and  maturing  liabilities.  Insufficient
liquidity can  result  in  higher  costs of  obtaining  funds,  while  excessive
liquidity  can  lead to  a  decline in  earnings due  to  the cost  of foregoing
alternative investments.  The ability  to renew  or acquire  additional  deposit
liabilities  is a major source of  liquidity. Border Bank's principal sources of
funds are  primarily within  the local  markets of  Border Bank  and consist  of
deposits, interest and principal payments on loans and investment securities.
 
    Asset liquidity is provided by cash and assets which are readily marketable,
or  which can be pledged, or which will mature in the near future. These include
cash, federal funds sold and U.S. Government-backed securities. At December  31,
1995,  Border Bank's  liquidity ratio,  defined as  cash, U.S. Government-backed
securities, and  federal  funds sold  as  a  percentage of  deposits  was  45.8%
compared  to 43.6% at  December 31, 1994  and compared to  39.0% at December 31,
1993.
 
    Liability  liquidity  is  provided  by  access  to  core  funding   sources,
principally  various customers' interest-bearing and noninterest-bearing deposit
accounts in Border Bank's trade area.
 
    During 1995,  funds  for $10.7  million  of investment  purchases  and  $1.9
million  of net loan growth came from  various sources, including a net increase
in deposits of  $1.1 million,  $15.6 million  proceeds from  maturing or  called
securities and $1.9 million of net income.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
requires  that  federal  bank  regulatory  authorities  take  "prompt corrective
action" with respect to any depository institution which does not meet specified
minimum capital requirements. The applicable regulations establish five  capital
levels  which require or  permit the Federal  Deposit Insurance Corporation (the
"FDIC") and  other  regulatory  authorities  to  take  supervisory  action.  The
relevant   classifications   range  from   "well  capitalized"   to  "critically
capitalized." The classifications are generally determined by applicable  ratios
of  the institution,  including Tier  I capital  to risk-weighted  assets, total
capital to  risk-weighted assets  and leverage  ratios. Based  on Border  Bank's
capital  ratios  at  December 31,  1995,  Border  Bank was  classified  as "well
capitalized" under the applicable regulations. As a result, Border Bank does not
believe that the prompt corrective  action regulations have any material  effect
on its activities or operations.
 
    The  funds  management policy  of  Border Bank  is  to maintain  a liability
sensitive position. Changes in net interest income occur when interest rates  on
loans  and investments change in a different time period from that of changes in
interest rates on liabilities,  or when the mix  and volume of  interest-earning
assets  and interest-bearing  liabilities change. The  interest rate sensitivity
gap represents the dollar amount of
 
                                     F-108
<PAGE>
difference between rate sensitive assets and rate sensitive liabilities within a
given time period ("GAP"). A GAP ratio is determined by dividing rate  sensitive
assets  by  rate sensitive  liabilities. A  ratio of  1.0 indicates  a perfectly
matched position,  in  which case  the  effect on  net  interest income  due  to
interest rate movements would be zero.
 
    Rate  sensitive liabilities maturing within one year exceeded rate sensitive
assets with comparable maturities at December 31, 1995 by $33.2 million.

EFFECTS OF INFLATION
 
    Financial institutions  are  impacted  differently  by  inflation  than  are
industrial  companies.  While industrial  and manufacturing  companies generally
have  significant  investments  in  inventories  and  fixed  assets,   financial
institutions  ordinarily do  not have such  investments. As  a result, financial
institutions are generally  in a  better position than  industrial companies  to
respond  to inflationary trends by monitoring  the spread between interest costs
and interest income yields through adjustments to maturities and interest  rates
of  assets and liabilities. In addition,  inflation tends to increase demand for
loans from financial institutions as industrial companies attempt to maintain  a
constant  level of  goods in  inventory and  assets. As  consumers of  goods and
services, financial institutions are affected  by inflation as prices  increase,
causing  an increase in costs of  salaries, employee benefits, occupancy expense
and similar items.
 
CAPITAL RESOURCES
 
    Stockholders' equity of $17.1  million at December 31,  1995 reflects a  net
increase  of  $1.2 million  or 7.8%  compared to  stockholders' equity  of $15.8
million at December 31,  1994. This net increase  was primarily attributable  to
earnings  for 1995  of $1.9  million. The  net increase  in stockholders' equity
reflects dividends paid on  common stock of $800  thousand in 1995. Border  Bank
also declared and paid a $500 thousand dividend in January 1996.
 
    The  risk-based capital standards as established by the FDIC apply to Border
Bank. The numerator of  the risk-based capital ratio  for banks includes Tier  I
capital, consisting of common stockholders' equity and qualifying cumulative and
noncumulative  perpetual  preferred stock;  and Tier  II capital,  consisting of
 
                                     F-110
<PAGE>
other preferred stock, reserve for possible loan losses and certain subordinated
and term-debt securities. Beginning on  December 31, 1993, goodwill is  deducted
from  Tier I capital.  At no time  is Tier II  capital allowed to  exceed Tier I
capital in the calculation of total capital. The denominator or asset portion of
the risk-based capital  ratio aggregates  generic classes of  balance sheet  and
off-balance  sheet exposures, each weighted by one of four factors, ranging from
0% to 100%, based on the relative risk of the exposure class.
 
    Ratio targets are set for both Tier I capital and Total Capital (Tier I plus
Tier II capital). The minimum  level of Tier I capital  to total assets is  4.0%
and  the minimum  Total Capital  ratio is  8.0%. The  FDIC has  guidelines for a
leverage ratio that is  an additional evaluation of  capital adequacy of  banks.
The  leverage ratio is defined to be Border Bank's Tier I capital divided by its
risk  adjusted  total  assets.  An  insured  depository  institution  is   "Well
Capitalized"  for purposes  of FDICIA if  its Total Risk-Based  Capital Ratio is
equal to or greater than 10.0%, and Tier I Risk-Based Capital Ratio is equal  to
or  greater than 6.0%, and Tier I Leverage  Capital Ratio is equal to or greater
than 5.0%. Based  on capital  ratios, Border Bank  is within  the definition  of
"Well Capitalized" for FDIC purposes at December 31, 1995.
 
    Border  Bank's Tier I Risk-Based Capital  Ratio was approximately 18.12% and
18.01% at  December  31,  1995  and  1994,  respectively.  Border  Bank's  Total
Risk-Based  Capital Ratio  was approximately 19.29%  and 19.02%  at December 31,
1995 and 1994,  respectively. Border Bank's  Tier I Leverage  Capital Ratio  was
approximately 14.51% and 13.58% at December 31, 1995 and 1994, respectively.

CURRENT ACCOUNTING ISSUES
 
    Effective  January  1,  1995,  Border Bank  adopted  Statement  114  and the
amendment thereof,  Statement 118.  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.
 
                                     F-111
<PAGE>
    For  loans covered  by Statement  114, Border  Bank makes  an assessment for
impairment when and while such loans are  on nonaccrual status 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
Border  Bank using discounted cash flows, except  when it is determined that the
sole source of repayment  for the loan  is the operation  or liquidation of  the
underlying  collateral. In such case, the  current 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.
 
    In management's opinion, the adoption of Statement 114 and Statement 118 has
not had, and  is not anticipated  to have,  a material effect  on Border  Bank's
results of operations.
 
    In October 1995, the FASB issued Statement of Financial Accounting Standards
No.  123 ("Statement 123"), "Accounting for Stock-Based Compensation." Statement
123 establishes  financial accounting  and reporting  standards for  stock-based
employee compensation plans.
 
    Statement  123 encourages entities  to adopt a "fair  value" based method of
accounting for stock-based compensation plans which requires an estimate of  the
fair  value of stock options or  other equity instruments which employees become
entitled to  when  they  have  rendered requisite  service  or  satisfied  other
conditions  necessary  to  earn  the  right  to  benefit  from  the instruments.
Compensation cost is  then determined based  on the fair  value estimate and  is
recognized  over  the  service  period, which  is  usually  the  vesting period.
Statement 123  also requires  that an  employer's financial  statements  include
certain   disclosures  about  stock-based   employee  compensation  arrangements
regardless of the method used to account for them.
 
    The accounting requirements of Statement 123 are effective for  transactions
entered into in fiscal years that begin after December 15, 1995. In management's
opinion,  the implementation of Statement 123  should have no material effect on
Border Bank's financial statements.

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
 
NOTE 1 -- BASIS OF PRESENTATION
    The  accompanying  unaudited  financial  information  does  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 information furnished reflects  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.
 
NOTE 2 -- INCOME TAX
    Deferred  income  tax assets  and liabilities  are computed  for differences
between the financial statement 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 effect  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

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
The Border Bank:
 
    We  have audited  the accompanying  balance sheets  of The  Border Bank (the
"Bank") as  of  December  31, 1995  and  1994,  and the  related  statements  of
earnings,  changes in stockholders' equity and cash  flows for each of the years
in the three-year period ended December 31, 1995. These financial statements are
the responsibility of the Bank's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all  material respects,  the financial  position  of The  Border Bank  as of
December 31, 1995 and 1994, and the results of its operations and its cash flows
for the each of the  years in the three-year period  ended December 31, 1995  in
conformity with generally accepted accounting principles.
 
    As  discussed in note  1 to the  financial statements, the  Bank changed its
method of accounting for investment securities  in 1994 to adopt the  provisions
of  Statement of Financial Accounting Standards No. 115, "Accounting for Certain
Investments in Debt and Equity Securities."

                                THE BORDER BANK
 
                         NOTES TO FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1995, 1994 AND 1993
 
(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    The  accounting  and reporting  policies of  the  Bank conform  to generally
accepted accounting principles  and to prevailing  practices within the  banking
industry. A summary of the more significant accounting policies follows:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported amounts  of  assets and  liabilities and
disclosure of contingent  assets and liabilities  at the date  of the  financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
    For purposes of reporting  cash flows, cash and  due from banks and  federal
funds  sold are considered to be  cash equivalents. Federal funds sold generally
have one-day maturities.
 
INVESTMENT SECURITIES
 
    In May  1993,  the  Financial Accounting  Standards  Board  ("FASB")  issued
Statement   of  Financial  Accounting  Standards   No.  115  ("Statement  115"),
"Accounting for Certain  Investments in Debt  and Equity Securities."  Statement
115  establishes standards of financial accounting and reporting for investments
in equity securities  that have a  readily determinable fair  value and for  all
investments  in debt 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 balance sheet 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 balance sheet with unrealized holding gains and losses included in
earnings. Investments  not  classified  as  held to  maturity  nor  trading  are
classified as available for sale and measured at fair value in the balance sheet
with  unrealized  holding  gains and  losses,  net of  applicable  income taxes,
reported in a separate component of stockholders' equity until realized.
 
    Effective January 1,  1994, the  Bank adopted  Statement 115,  which had  no
impact  on  the Bank's  income statement  as all  securities were  classified as
either held  to  maturity  or  available for  sale.  Accounting  for  securities
classified  as held to  maturity will continue  on the basis  of amortized cost.
Securities classified as  available for sale  will be measured  at market  value
with  the  net  unrealized  holding  gains and  losses  reported  in  a separate
component of  stockholders'  equity  until  realized.  Purchases  of  investment
securities  are classified as available for sale  or held to maturity at time of
purchase as determined by management.
 
    Premiums and  discounts are  amortized  and accreted  using a  method  which
approximates  level yield.  Gains and  losses on  available for  sale investment
securities sold are recognized in  operations at the time  of sale based on  the
specific identification method. Security purchases and sales are recorded on the
trade date.
 
LOANS
 
    Management  continually reviews the loan  portfolio to identify loans which,
with respect to principal or interest, have or may become collection problems. 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

(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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  on
management's assessment of the ultimate collectibility of principal.
 
    Unearned  interest on  installment loans  is recognized  as income  over the
terms of the related loans on a basis which results in approximately level rates
of return over the terms of the loans.
 
    In May 1993, the FASB issued Statement of Financial Accounting Standards No.
114 ("Statement 114"), "Accounting by Creditors for Impairment of a Loan," which
addresses the  accounting  by creditors  for  impairment of  certain  loans,  as
defined.  In October 1994,  Statement 114 was amended  by Statement of Financial
Accounting Standards No. 118, "Accounting by Creditors for Impairment of a Loan,
Income Recognition and Disclosures."  Implementation of these pronouncements  in
the first quarter of 1995 did not have a material effect on the Bank's financial
statements.
 
ALLOWANCE FOR LOAN LOSSES
 
    The  allowance for loan losses  is established by a  charge to operations as
deemed necessary by management to maintain  the allowance for loan losses at  an
amount considered adequate to absorb known or possible loan losses in the Bank's
loan  portfolio. The provision is determined based on management's evaluation of
the loan  portfolio,  giving  consideration  to  existing  economic  conditions,
changes  in the loan portfolio, historical  loan loss factors and other relevant
information. Management believes that the allowance for loan losses is adequate.
 
    Loans are  charged against  the allowance  for loan  losses when  management
believes  the  collection  of  principal  is  unlikely.  Recoveries  of  amounts
previously charged off are credited to the allowance.
 
BANK PREMISES AND EQUIPMENT
 
    Bank  premises  and  equipment  are  recorded  at  cost.  Expenditures   for
improvements  are capitalized. Repairs  and maintenance which  do not extend the
life of  bank  premises  and  equipment are  charged  to  expense  as  incurred.
Depreciation and amortization are calculated using the straight-line method over
the  estimated  useful lives  of the  assets.  Any gain  or loss  resulting from
disposition of premises and equipment is reflected in earnings.
 
OTHER REAL ESTATE OWNED
 
    Other real estate owned is recorded at fair value at the date of foreclosure
which is subsequently considered cost. At subsequent dates, other real estate is
carried at the lower of fair value  minus estimated costs to sell or cost.  Fair
values are determined generally by reference to appraisals. Rental income earned
and  expenses incurred  related to real  estate owned are  recognized during the
period earned or incurred and are  included in noninterest expense at their  net
amount.
 
FEDERAL INCOME TAXES
 
    Deferred  tax assets and liabilities are recognized for estimated future tax
consequences  attributable  to  differences  between  the  financial   statement
carrying  amounts of  existing assets and  liabilities and  their respective tax
bases, and operating loss and tax credit carryforwards. Deferred tax assets  and
liabilities  are measured using tax rates expected to apply to taxable income in
the years in which those temporary  differences are expected to be recovered  or
settled. Deferred tax expense or benefit is recognized as a result of the change
in the asset or liability during the year.

(2)   RESERVE REQUIREMENTS
    The  Bank is required to maintain certain  daily reserve balances on hand or
on deposit with  the Federal  Reserve Bank  in accordance  with Federal  Reserve
Board requirements. These deposits are noninterest bearing and not available for
investment  purposes. Cash and  due from bank  balances maintained in accordance
with such requirements at December 31, 1995 was approximately $25,000.
 
(3)   INVESTMENT SECURITIES
    The amortized cost and estimated market value, which is the carrying  value,
of  investment securities available  for sale at December  31, 1995 and December
31, 1994 are as follows:

interest rate on the other securities could reset to zero. No loss of  principal
is anticipated by management on any of the aforementioned securities.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(4)   LOANS (CONTINUED)
    The majority of the Bank's loans are to companies and individuals which  are
headquartered or are employed in the Rio Grande Valley, but may conduct business
on  a statewide  national or  international scale.  Repayment of  those loans is
dependent on the  economy in  that area, the  economic situation  in Mexico  and
surrounding areas.
 
    The  Border Bank makes loans to  individuals or companies that are residents
of, or domiciled  in, Mexico. Such  loans may be  secured or unsecured.  Secured
loans  include loans secured by deposits in  the Bank, real estate in the United
States or Mexico,  or equipment. At  December 31,  1995 and 1994,  the Bank  had
outstanding  approximately  $11,826,000 and  $12,178,000, respectively,  of such
loans. Interest income related  to such loans for  the years ended December  31,
1995,  1994  and 1993  was  approximately $1,329,000,  $732,000  and $1,110,000,
respectively.
 
    All loans to officers, directors and stockholders of the Bank and associates
of such persons are, in the opinion  of management, made in the ordinary  course
of  business  on  substantially the  same  terms, including  interest  rates and
collateral, as those prevailing at the time for comparable loans of like quality
and risk  of collectibility.  The  outstanding balance  of direct  and  indirect
personal  borrowings of executive officers and directors of the Bank at December
31, 1995 and 1994 was approximately $1,704,000 and $2,403,000, respectively.
 
    Nonaccrual loans approximated $189,000 and $226,000 at December 31, 1995 and
1994, respectively. If interest on these loans had been accrued at the  original
contractual  rates, interest income  would have been  increased by approximately
$2,400 and $34,000 for the years ended December 31, 1995 and 1994. There were no
renegotiated loans outstanding at December 31, 1995 and 1994.
 
    In the normal course of business, the Bank enters into various  transactions
which,  in  accordance with  generally accepted  accounting principles,  are not
included  on  the  balance  sheets.  These  transactions  are  referred  to   as
"off-balance sheet commitments." The Bank 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.  The
Bank  minimizes its exposure to loss  under these commitments by subjecting them
to credit approval and monitoring procedures.
 
    Outstanding commitments and letters of credit at December 31, 1995 and  1994
are approximately as follows:

</TABLE>
 
    Management  believes that  it is  more likely than  not that  the results of
future operations  will  generate  sufficient  taxable  income  to  realize  the
deferred tax assets.
 
(9)   EMPLOYEE BENEFITS
    The Bank has a deferred compensation plan for the benefit of one individual.
The  plan  provides for  a  retirement benefit,  payable  to the  individual (or
designated beneficiary or estate  if death occurs prior  to payment of the  full
amount  of deferred compensation), of $13,350 each year beginning March 15, 1995
and continuing thereafter for fourteen years.
 
    The Bank owns  and is  the beneficiary  of a  life insurance  policy on  the
former employee covered by the deferred compensation plan. The face value of the
life  insurance policy is approximately  equal to the total  benefits to be paid
under the plan.
 
(10)  CONTINGENT LIABILITIES
    The Bank is involved in certain  claims and suits occurring in the  ordinary
course  of business.  Management believes that  the probable  resolution of such
claims and  suits will  not have  a  material adverse  affect on  the  financial
condition of the Bank.

</TABLE>
 
CASH AND DUE FROM BANKS
 
    Carrying  value approximates  fair value  because of  the short  maturity of
these instruments and no anticipated credit concerns.
 
FEDERAL FUNDS SOLD
 
    Carrying value  approximates fair  value because  of the  short maturity  of
these instruments and no anticipated credit concerns.
 
INVESTMENT SECURITIES
 
    The  fair  values of  investment securities  are  estimated based  on quoted
market prices from investment dealers and companies.
 
NET LOANS
 
    The fair value of loans is estimated for segregated groupings of loans  with
similar  financial characteristics.  Loans are segregated  by type  and the fair
value of loans is estimated using current market rates for the type of loan.
 
DEPOSITS
 
    The fair value of  deposits with short-term or  no stated maturity, such  as
checking,  savings,  NOW accounts  and money  market accounts,  is equal  to the
amounts payable at December 31, 1995. The fair value of certificates of deposits
is based on the discounted value of contractual cash flows. The discount rate is
estimated using the rates  currently offered for  deposits of similar  remaining
maturities.
 
COMMITMENTS TO EXTEND CREDIT AND LETTERS OF CREDIT
 
    The  fair value of  commitments to extend  credit and letters  of credit are
estimated using current interest rates and committed rates.
 
(12)  REGULATORY SUPERVISION
    As a  result  of  criticisms  reflected  in the  June  28,  1993  Report  of
Examination  by the Texas  Department of Banking,  a Memorandum of Understanding
(the "Memorandum") was entered into between  the Board of Directors of the  Bank
and  the  Banking  Commissioner of  Texas  on  October 8,  1993.  The Memorandum
required that  the Bank,  among  other provisions,  increase Board  of  Director
supervision  over loan activities, revise the existing loan policy, increase the
allowance for loan losses and reduce criticized assets. Additionally, the Bank's
Board of  Directors are  required to  submit to  the Commissioner  and  Regional
Director  of the FDIC, a written report of  the actions taken to comply with the
Memorandum

(12)  REGULATORY SUPERVISION (CONTINUED)
within fifteen days after  the end of each  calendar quarter. Failure to  comply
with  the requirements  of the Memorandum  could subject the  Bank to additional
action by bank  regulatory authorities.  Management has made  efforts to  comply
with the requirements of the Memorandum and believes such additional action will
not be taken by regulatory authorities.
 
(13)  PENDING TRANSACTION
    On January 9, 1996, a definitive agreement was signed under which the Border
Bank  will be purchased by Texas  State Bank, the principal operating subsidiary
of Texas Regional Bancshares, Inc. The agreement has been approved by the Boards
of Directors of the Border Bank, Texas State Bank and Texas Regional Bancshares,
Inc. The sale of the Bank is  subject to approval by the appropriate  regulatory
agencies  and contingent  upon, among  other things,  Texas Regional Bancshares,
Inc. having  successfully  raised  additional  capital  to  partially  fund  the
transaction.
 
(14)  SUBSEQUENT EVENT
