NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of National
Bancshares Corporation of Texas and its wholly-owned subsidiaries have been
prepared in accordance with generally accepted accounting principles for interim

Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
The consolidated financial statements include the accounts of the parent company
and all subsidiaries, and all significant intercompany balances and transactions
have been eliminated. Certain items in prior year's financial statements have

(consisting primarily of normal recurring accruals) which, in the opinion of
management, are necessary for a fair statement of the results of the periods
presented. The results of operations for the three month period ended March 31,
1998 are not necessarily indicative of the results that may be reported for the
entire year. For further information, refer to the consolidated financial
statements and footnotes thereto included in the Company's Form 10-K for the
year ended December 31, 1997.


NOTE 2 - SUBSIDIARIES

The carrying value of investment securities pledged to secure public funds
amounted to approximately $42,850,000 at March 31, 1998 and $36,167,000 at
December 31, 1997.

At March 31, 1998, the Company had one short investment position totaling
$2,078,000 which was included in obligation from short-sale transactions. At
March 31, 1998, the Company recorded a net unrealized loss of $88,000 on this
position. Short sales can result in off-balance sheet risk, as losses can be
incurred in excess of the reported obligation if market prices of the securities
subsequently increase.

IMPAIRED LOANS

A loan within the scope of SFAS No. 114 is considered impaired when, based on
current information and events, it is probable that the Company will be unable
to collect all amounts due according to the contractual terms of the loan
agreement, including scheduled principal and interest payments. At March 31,
1998 and 1997, the Banks have impaired loans of $1,216,000 and $1,071,000,
respectively. The allowance for loan losses related to those loans was $242,000
and $95,000, respectively. The average recorded investment in impaired loans
during the three months ended March 31, 1998 was $1,274,000 and $1,133,000,
respectively. Interest income of approximately $19,000 and $25,000 on impaired
loans was recognized for cash payments received during the three months ended
March 31, 1998 and 1997, respectively.

NOTE 5 - NOTES PAYABLE

On September 30, 1997, the Company executed a $4 million note with Texas
Independent Bank in Dallas. The note bears a variable interest rate at New York
prime (8.5% at March 31, 1998). Principal payments of $200,000 plus interest are
due quarterly, with the balance due at maturity. The note matures on September
30, 2000. The note is collateralized by the common stock of NBT of Delaware,
Inc. and the stock of the subsidiary banks.

In May 1994 and July 1995, a subsidiary Bank borrowed $200,000 and $175,000,
respectively, from the Federal Home Loan Bank of Dallas. The notes bear interest
rates of 7.49% and 6.393%, respectively. The maturity dates of the notes are
June 1999 and August 2015, respectively. Principal and interest payments are due
monthly in the approximate amount of $2,900 per month in the aggregate with the
remaining balances due at maturity. Both of these loans are secured by a certain
block of fixed rate mortgage loans carried by the subsidiary Bank.

NOTE 6 - INCOME TAX EXPENSE

The provision for Federal income tax expense is less than that computed by
applying the federal statutory rate of 34% as indicated in the following
analysis:

</TABLE>


The Company had approximately $103 million in net operating loss carryforwards
at March 31, 1998 which will be available to reduce income tax liabilities in
future years. If unused, approximately $99 million of such carryforwards will
expire in 2005, with the remaining approximately $4 million expiring in 2006.
The net operating loss carryforwards, along with certain other items, create
deferred tax assets. A valuation allowance has been created to reduce deferred
tax assets to an amount more likely than not to be realized. During the three
months ended March 31, 1998 and 1997, the valuation allowance has been reduced
to adjust the recorded deferred tax asset to the realizable amount. Pursuant to
Statement of Financial Accounting Standards No, 109, "Accounting for Income
Taxes", reductions to the valuation allowance are recorded as decreases in
current period income tax expense.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS



         Management's Discussion and Analysis of Financial Condition and Results
of Operations of the Company analyzes the major elements of the Company's
consolidated balance sheets and statements of income. This discussion should be
read in conjunction with the Consolidated Financial Statements, accompanying
notes, and selected financial data appearing elsewhere in this Report.



RESULTS OF OPERATIONS

         Net income for the three months ended March 31, 1998 was $3.3 million
or $.70 per common share compared with $2.6 million or $.56 per common share for
the three months ended March 31, 1997. The first quarter of the current and the
previous year included non-recurring gains on investment securities. The
amount of the gains were $1.8 million and $1.1 million, net of tax, for the
three months ended March 31, 1998 and 1997, respectively. With the exclusion of
the non-recurring gains, net income for the first quarter of 1998 was $1.4
million, or $.31 per share, and $1.6 million or $.33 per share for the first
quarter of 1997. Net interest income for the three months ended March 31, 1998
improved $900,000 over the same period of 1997 of which $775,000 or 86% is due
to internal growth in the loan portfolio and the remainder is primarily due to
the Wells Fargo acquisitions. Net interest income was comparable to the previous
quarter ended December 31, 1997. Non-interest expenses were up $1.1 million, or
44%, for the three months ended March 31, 1998, which was primarily due to
the expenses of operating the Wells Fargo branches and the opening of two new
branches in the first quarter of 1998. Non-interest income improved $104,000 or
14% for the three months ended March 31, 1998, due to service charges and fees
primarily from the Wells Fargo acquisitions.

         For the three months ended March 31, 1998, the Company's return on
average assets was 2.79%, or 1.20% deducting the non-recurring gains on
securities, compared to 3.21% and 1.87%, deducting the non-recurring gains on
securities, for the three months ended March 31, 1997. Average assets have
increased $137.8 million or 42% over the quarter ended March 31, 1997. The
Company's return on average equity for the three months ended March 31, 1998 was
25.79%, or 11.10% deducting the gains on securities, compared to 24.63% and
14.36%, deducting the gain on securities, for the three months ended March 31,
1997. The ratio of average stockholders' equity to total average assets was
10.8% and 13.0% for the three months ended March 31, 1998 and 1997,
respectively.


NET INTEREST INCOME

         Net interest income constitutes the principal source of income for the
Banks and represents the difference between interest income on interest-earning
assets and interest expense on interest-bearing liabilities. The increase of
$900,000 or 26% in net interest income for the three months ended March 31,1998
compared to the same period in 1997 was due to internal loan growth which
accounts for $775,000 of the increase and the remainder is due to the Wells
Fargo acquisitions. Average loans increased $30 million or 27% over the first
quarter of 1997. The net interest margin for the three months ended March 31,
1998 was 4.17% compared to 4.57% as of March 31, 1997. The net interest margin
is the net return on earning assets which is computed by dividing taxable
equivalent net interest income by average total earning assets.

           The net interest spread decreased 16 basis points to 3.60% at March
31, 1998 from 3.76% at March 31, 1997. The decrease in the net interest spread
is primarily due to the increase in rates being paid on deposits and the
decrease in the rates being paid on loans.

         The following table analyzes the increase in taxable-equivalent net
interest income stemming from changes in interest rates and from asset and
liability volume, including mix, for the three ended March 31, 1998 and 1997.
Non-accruing loans have been included in assets for calculating this table,
thereby reducing the yield on loans. The changes in interest due to both rate
and volume in the table below have been allocated to volume or rate change on a
pro-rata basis.

         Taxable-equivalent net interest income for the three months ended March
31, 1998 increased $900,000 or 26% over the same period in 1997. The increase is
reflected in the increase in the volume of earning assets and in the increase in
the market rates and volume of interest bearing liabilities.

INTEREST RATE SENSITIVITY

         Management seeks to maintain consistent growth of net interest income
through periods of changing interest rates by avoiding fluctuating net interest
margins. Interest rate sensitivity is the relationship between changes in market
interest rates and changes in net interest income due to repricing
characteristics of interest earning assets and liabilities.

         The interest rate sensitivity table reflects a cumulative liability
sensitive position during the one year period shown. Generally, this indicates
that the liabilities reprice more quickly than the assets in a given period, and
that a decline in market rates will benefit net interest income. An increase in
market rates would have the opposite effect.

</TABLE>


         The $852,000 or 46.0% increase in non-interest income for the three
months ended March 31, 1998 is due primarily to the $748,000 increase in net
gains and trading account profits over the first quarter of 1997. Excluding the
nonrecurring gains on sales of securities and other real estate owned,
non-interest income increased $111,000 or 14.7% over 1997. The Wells Fargo
branch acquisitions represent the majority of the increase over the prior year
in service charges and fees.

NON-INTEREST EXPENSE

         Non-interest expense includes all expenses of the Company other than
interest expense, loan loss provision and income tax expense. The following

</TABLE>


         Total non-interest expense for the three months ended March 31, 1998
increased $1,114,000 or 43.6% over 1997. Salaries and benefits rose $464,000 or
33.9% in 1998. Approximately $200,000 or 43% of the increase is related to the
acquisition of the Wells Fargo Bank branches in July 1997. Another factor
increasing salaries and benefits is due to the hiring of additional personnel
for the San Marcos and South Laredo branches which were opened during the first
quarter of 1998. The $152,000 or 36.3% increase in occupancy and equipment
expenses is due mainly to the acquisitions of three bank buildings, the building
of two new branches and to the installation of computer networks at the new
locations. The $87,000 increase in goodwill is a result of the Wells Fargo
branch acquisitions.

INCOME TAXES

         The Company recognized income tax expense of $60,000 for the three
months ended March 31, 1998 compared to $61,000 for the three months ended March
31, 1997. At March 31, 1998, the Company had approximately $103 million in net
operating loss carryforwards that will be available to reduce income tax
liabilities in future years. If unused, approximately $99 million of such
carryforwards will expire in 2005, with the remaining approximately $4 million
expiring in 2006.

</TABLE>


         Real estate mortgage loans have shown a 14% and 19% increase since
December 31, 1997 and March 31, 1997, respectively. Real estate loan demand has
increased due to the banks offering home equity loans. The 25% increase in total
loans since December 31, 1997 has been from internal growth. No loans were
acquired from the Wells Fargo branch acquisition.

ALLOWANCE FOR LOAN LOSSES

         The allowance for loan losses is established through charges to
operations in the form of a provision for loan losses. Loans, or portions
thereof, which are considered to be uncollectible are charged against the
allowance and subsequent recoveries, if any, are credited to the allowance. The
allowance represents the amount, which in the judgment of each subsidiary Bank's
management will be adequate to absorb possible losses. The adequacy of the
allowance is determined by management's continuous evaluation of the loan
portfolio and by the employment of third party loan review consultants. Industry
concentrations, specific credit risks, past loan loss experience, delinquency
ratios, current loan portfolio quality and projected economic conditions in the
Bank's market areas are pertinent factors in determining the adequacy of the
allowance for loan losses. Loans identified as losses by management, external
loan review or bank examiners are charged-off.

         The Company recorded net recoveries of $34,000 for the three months
ended March 31, 1998 compared to net charge-offs of $2,000 for the three months
ended March 31, 1997.

NON-PERFORMING ASSETS

         Non-performing assets consist of non-accrual loans and foreclosed real
estate. Loans to a customer whose financial condition has deteriorated are
considered for non-accrual status whether or not the loan is ninety days or more
past due. All installment loans past due ninety days or more are placed on
non-accrual unless the loan is well secured or in the process of collection. On
non-accrual loans, interest income is not recognized until actually collected.
At the time the loan is placed on non-accrual status, interest previously
accrued but not collected is reversed and charged against current income.

         Foreclosed real estate consists of property which has been acquired
through foreclosure. At the time of foreclosure, the property is recorded at the
lower of the estimated fair value less selling expenses or the loan balance with
any write down charged to the allowance for loan losses. Any future write downs
on the property are charged to operations.

         Independent third party loan reviews of the subsidiary Banks are
performed on an annual basis. The loans are also reviewed by banking regulators
on an eighteen month basis. On a monthly basis, the Board of Directors' Loan
Committee of each Bank reviews new loans, renewals and delinquencies. Management
of each Bank monitors on a continuing basis those loans which it feels should be
followed closely. The Banks are required by regulation to have foreclosed real
estate appraised periodically.


LIQUIDITY

         Liquidity is the ability to have funds available at all times to meet
the commitments of the Company. Asset liquidity is provided by cash and assets
which are readily marketable or pledgeable or which will mature in the near
future. Liquid assets include cash and short-term investments in time deposits
in banks, federal funds sold and securities available for sale. Liquidity is
also provided by access to core funding sources, primarily core depositors in
the Company's trade area. The Banks have not and do not solicit brokered
deposits as a funding source. The liquidity of the Company is enhanced by the
fact that 82% of total deposits at March 31, 1998 were "core" deposits. Core
deposits, for this purpose, are defined as total deposits less public funds and
certificates of deposit greater than $100,000.

         At March 31, 1998, the Company's liquid assets amounted to $193 million
or 41% of total gross assets, compared to 39% at March 31, 1997. Secondary
sources of liquidity include the Banks' ability to sell loan participations and
purchase federal funds. NBC-Eagle Pass has an approved federal funds line at a
correspondent bank. NBC - Laredo has an approved line of credit with the
Federal Home Loan Bank.

         The Company's principal source of funds consists of dividends received
from the Banks, which derive their funds from deposits, interest and principal
payments on loans and investment securities, sales of investment securities and
borrowings.


CAPITAL RESOURCES

          Total stockholders' equity increased $10.7 million to $54.8 million at
March 31, 1998 from $44.1 million at March 31, 1997. The ratio of total
stockholders' equity to total assets was 11.5% at March 31, 1998 compared with
13.2% at March 31, 1997.

         The Company and subsidiary Banks are subject to minimum capital ratios
mandated by their respective banking industry regulators. The table below
illustrates the Company and subsidiary Bank's compliance with the risk-based
capital guidelines of the Federal Reserve Bank (FRB) and the Office of the
Comptroller of the Currency (OCC). These guidelines are designed to measure Tier
1 and total capital while taking into consideration the risk inherent in both on
and off balance sheet items. Off balance sheet items include unfunded loan
commitments and letters of credit. Currently under the regulatory guidelines,
the net unrealized gain or loss on securities available for sale is not included
in the calculation of risk-based capital and the leverage ratio. The leverage
ratio is Tier 1 capital divided by average total assets. A leverage ratio of 3.0
percent is the minimum requirement for only the most highly rated banking
organizations and all other institutions are required to maintain a leverage
ratio of 3 to 5 percent.

         Tier 1 capital includes common stockholders' equity less goodwill.
Total capital includes Tier 1 capital and a portion of the allowance for loan
losses. The ratios are calculated by dividing the qualifying capital by the
risk-weighted assets.

         The table below illustrates the Company and its subsidiary Banks'
compliance with the risk-based capital guidelines as of March 31, 1998:
