ITEM 1.  DESCRIPTION OF BUSINESS

THE COMPANY

         National Bancshares Corporation of Texas (the "Company") is a bank
holding company incorporated in Texas on June 14, 1971, and registered under the
Bank Holding Company Act of 1956, as amended (the "BHC Act"). The Company
successfully emerged from reorganization (the "Reorganization") under Chapter 11
of the United States Bankruptcy Code in May 1992. As a result of the
Reorganization, the Company came under new management and control and its assets
and liabilities were substantially restructured. The Company now conducts its
banking operations through NBC Bank-Laredo, N.A., Laredo, Texas, ("NBC-Laredo"),
NBC Bank, N.A., Eagle Pass, Texas ("NBC-Eagle Pass"), NBC Bank, Rockdale, Texas
("NBC-Rockdale") and NBC Bank Central, N.A., Luling, Texas ("NBC-Luling"),
(collectively, the "Banks"). NBC-Laredo, NBC-Eagle Pass, NBC-Rockdale and
NBC-Luling are wholly-owned subsidiaries of NBT of Delaware, Inc., a Delaware
corporation that is a wholly-owned subsidiary of the Company. The Company
operates its data and item processing for the Banks through NBC Holdings-Texas,
Inc., a wholly-owned subsidiary of NBT of Delaware, Inc. At December 31, 1998,
the Company (on a consolidated basis) had total assets of $512.1 million, total
investments securities of $232.5 million, total loans of $192.2 million, total
deposits of $447.7 million, total stockholders' equity of $52.2 million and net
operating loss carry-forwards for federal income tax purposes of $95 million.
For the year ended December 31, 1998, the Company recorded net income of $5.3
million.

         During 1997, the Company acquired three branches of Wells Fargo Bank in
the Texas cities of Giddings, Taylor and Marble Falls. The Company acquired
approximately $103.4 million in deposits and $2.6 million in the owned branch
facilities, branch furniture, fixtures and certain equipment. In 1996, the
Company acquired Luling Bancshares, Inc., including its subsidiary, The First
National Bank in Luling, in Luling, Texas. The Company acquired approximately
$26 million in total assets and assumed liabilities of approximately $24
million.

         The Company's executive offices are located at 12400 Hwy 281 North, San
Antonio, Texas 78216-2811, and its telephone number is (210) 403-4200.

THE BANKS

         Each of the Banks is a separate entity which operates under the
day-to-day management of its own board of directors and officers. The Banks
grant agribusiness, commercial, residential and installment loans to customers
primarily in Central and South Texas. The Banks also offer a range of commercial
banking services, including acceptance of deposits and providing letters of
credit. Deposit services include certificates of deposit, individual retirement
accounts, checking accounts, interest-bearing checking accounts, savings
accounts and money market accounts. In addition, the Banks provide traveler's
checks, safe deposit boxes and other customary nondeposit banking services. The
Banks provide limited escrow services. NBC-Luling is the only subsidiary that
provides discount brokerage services at this time. NBC-Eagle Pass operates three
branches, one located in San Antonio, Texas, one located in Marble Falls, Texas
and one in Eagle Pass, Texas. NBC-Rockdale operates two branches, located in
Giddings and Taylor, Texas. NBC-Laredo operates one branch location in South
Laredo which opened in March 1998. NBC-Luling operates one branch located in San
Marcos, Texas which opened during the first quarter of 1998. Loans consist of
real estate loans, residential mortgages, construction loans, commercial loans
directed at small to middle market businesses and loans to individuals. In
addition, each of the Banks is subject to legal lending limits. Such limits
generally restrict loans to any one customer in an amount not to exceed 15% of
any one Bank's total capital plus the allowance for possible loan losses.

SERVICES OFFERED BY NBC SUBSIDIARY BANKS

COMMERCIAL BANKING

         The Banks provide the following types of loans for corporations and
other business clients:

         REAL ESTATE LOANS. The Banks have historically engaged in real estate
lending through construction and term mortgage loans, all of which are secured
by deeds of trust on underlying real estate. The majority of all of the Banks'
real estate loans are small and medium sized real estate loans.

         COMMERCIAL LOANS. Commercial loans include loans made primarily to
small and medium sized businesses and professionals for working capital.
Buildings for which the Banks have provided the construction financing secure
certain of the Banks' commercial loans.

         INSTALLMENT LOANS. Installment loans consist primarily of automobile
loans, loans made to finance small equipment acquisitions, small loans for
personal and household needs and home improvement loans. These loans are made
primarily as an accommodation to existing customers and are not a substantial
part of the Banks lending strategy.

         The Banks also provide deposit products to its commercial customers, as
well as night deposit and wire transfer services.

CONSUMER SERVICES

         The Banks have generated a substantial portion of its deposits from
individuals and small businesses in its immediate market areas. Other consumer
bank services include automated teller machines, installment and real estate
loans, home equity loans, drive-in services, safe deposit boxes, Internet
banking, image bank statements and credit card services. The Banks offer
competitive interest rates on money market accounts, savings accounts and
certificates of deposit. NBC-Eagle Pass and NBC-Laredo enjoy long-term deposit
relationships with many Mexican Nationals (in United States dollars only). The
Banks intend to add insurance and brokerage services in 1999.

COMPETITION

         The Banks face substantial competition for deposits and loans
throughout their market areas. The primary factors in competing for deposits are
interest rates, personalized services, the quality and range of financial
services offered, convenience of banking facilities and hours of operation.
Competition comes primarily from other commercial banks, savings and loans,
credit unions, mutual funds and other financial intermediaries. The Company
believes the primary factors in competing for loans are interest rates, loan
origination fees, the quality and range of lending services and personalized
services. The Banks face competition for deposits and loans throughout their
market areas not only from local institutions but also from out-of-state
financial intermediaries which have opened loan production offices which solicit
deposits in its market areas. Many of the financial intermediaries operating in
the Banks' market areas offer certain services, such as trust, investment and
international banking services, which the Company does not offer directly.
Additionally, banks with larger capitalization and financial intermediaries not
subject to bank regulatory restrictions have larger lending limits and are
thereby able to serve the needs of larger customers. Management believes,
however, that the Banks' long-term presence,


                                       4
<PAGE>   5

local expertise and ongoing commitment to the community, as well as their
commitment to quality and personalized banking services, are the key factors
that contribute to their competitiveness.

         Based on June 30, 1998 data, NBC-Laredo holds 2% of the total deposits
of its community. There are six local banks in the Laredo area as well as a
branch of Norwest Bank. The Laredo market is dominated by International Bank of
Commerce with approximately 33% of the community's total deposits and Laredo
National Bank with 42% of deposits. NBC-Eagle Pass is one of four banks located
in Eagle Pass, Texas and holds in excess of 62% of the community's banking
deposits. NBC-Rockdale is the largest bank in Rockdale holding over 45% of the
total deposits in the city and is the third largest of the five banks located in
Milam County, Texas holding approximately 19% of the county's deposits.
NBC-Luling is one of three banks located in Luling, Texas, holding over 37% of
the deposits of the city.

GROWTH OBJECTIVES

         The Company intends to grow its business in the State of Texas by
adding additional branches and through possible bank or branch acquisitions.
Because the Company has $95 million of net operating loss carryforwards as of
December 31, 1998, which will not begin to expire until 2005, the Company
believes it is well positioned to grow its business by acquiring additional
banks. The Company's ability and willingness to acquire additional banks is
dependent upon the (i) availability of suitable candidates, (ii) price, and
(iii) strategic fit for such additional banks and/or branches. Acquiring
additional banks or adding additional branches is also subject to certain
federal and state regulatory approvals. See "Supervision and Regulation -- The
Company" and "Supervision and Regulation -- Interstate Banking and Branching."
There can be no assurance, however, that the Company will obtain the required
regulatory approvals or that the Company will be able to successfully add
additional branches or acquire additional banks.

EMPLOYEES

         At December 31, 1998, the Company employed approximately 249 full-time
equivalent employees. Management believes that its relations with its employees
are satisfactory. Employees of the Company enjoy a variety of employee benefit
programs, including a 401(k) plan, paid vacations and comprehensive medical,
life and accident insurance plans.

SUPERVISION AND REGULATION

          THE COMPANY. The Company, as a registered bank holding company, is
subject to regulation under the BHC Act. The Company is required to file with
the Federal Reserve Board ("FRB") quarterly and annually and also reports such
additional information as the FRB may require pursuant to the BHC Act. The
Company is subject to examination by the FRB. The FRB may require the Company to
terminate an activity or terminate control of or liquidate or divest certain
subsidiaries or affiliates when the FRB believes the activity or the control of
the subsidiary or affiliate constitutes a significant risk to the financial
safety, soundness or stability of any of its banking subsidiaries. The FRB also
has the authority to regulate provisions of certain bank holding company debt,
including authority to impose interest ceilings and reserve requirements on such
debt. Under certain circumstances, the Company must file written notice and
obtain approval from the FRB prior to purchasing or redeeming its equity
securities. Under the BHC Act and regulations adopted by the FRB, a bank holding
company and its nonbanking subsidiaries are prohibited from requiring certain
tie-in arrangements in connection with any extension of credit, lease or sale of
property or furnishing of services. Further, the Company is required by the FRB
to maintain certain levels of capital. See "Supervision and Regulation--Capital
Adequacy Guidelines."

         The Company is required to obtain prior approval of the FRB for the
acquisition of more than five percent of the outstanding shares of any class of
voting securities or substantially all of the assets of any bank or bank holding
company. Prior approval of the FRB is also required for the merger or
consolidation of the Company and another bank holding company. The Company is
prohibited by the BHC Act, except in certain statutorily prescribed instances,
from acquiring direct or indirect ownership or control of more than five percent
of the outstanding voting shares of any company that 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 subsidiaries. However, the Company may, subject to the prior approval of the
FRB, engage in any, or acquire shares of companies engaged in, activities that
are deemed by the FRB to be so closely related to banking or managing or
controlling banks as to be a proper incident thereto. The FRB is also empowered
to differentiate between activities commenced de novo and activities commenced
by acquisition, in whole or in part, of a going concern and is generally
prohibited from approving an application by a bank holding company to acquire
voting shares of any commercial bank in another state unless such acquisition is
specifically authorized by the laws of such other state.


                                       5
<PAGE>   6

         Under FRB regulations, 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 unsound manner. In addition, it is the
FRB's policy 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's regulations or both.

         THE BANKS. Banks are extensively regulated under federal and state law.
NBC-Laredo, NBC-Eagle Pass and NBC-Luling, as national banks, are subject to
primary supervision, periodic examination and regulation by the Office of the
Comptroller of the Currency (the "OCC"). NBC-Rockdale, a Texas state chartered
bank, is subject to examination and regulation by the Texas State Banking
Department.

         The deposits of the Banks are insured by the Federal Deposit Insurance
Corporation ("FDIC"), which currently insures deposits of each member bank to a
maximum of $100,000 per depositor. For this protection, the Banks, as is the
case with all insured banks, pay a semi-annual statutory assessment and are
subject to the rules and regulations of the FDIC. See "Supervision and
Regulation - FDIC Insurance."

          The regulations promulgated by these federal agencies govern most
aspects of the Banks business, including, without limitation, capital to assets
ratios, reserves against deposits, maximum lending limitations, investments,
mergers and acquisitions, borrowings, dividends and locations of branch offices.
The Banks are also subject to applicable provisions of Texas law, insofar as
they do not conflict with or are not preempted by federal law. Supervision,
legal action and examination of the Banks by the regulatory agencies are
generally intended to protect depositors, and are not intended for the
protection of shareholders. The OCC also has the authority to prohibit national
banks from engaging in what, in the OCC's opinion, constitutes an unsafe or
unsound practice in conducting its business. It is possible, depending upon the
financial condition of the bank in question and other factors, that the OCC
could assert that the payment of dividends or other payments might, under some
circumstances, constitute an unsafe or unsound practice.

         CONTROL ISSUES. Investors in the Common Stock of the Company are
potentially subject to certain change of bank control laws; those contained in
the BHC Act, the Federal Deposit Insurance Act (the "FDIA") and applicable Texas
laws. In general, persons who wish to acquire a number of shares of Common Stock
that, when aggregated with that person's other holdings of common stock, if any,
would equal or exceed 10 percent of the Company's Common Stock, or who otherwise
might be subject to the change of bank control rules, should consult with their
legal counsel regarding the applicability of the provisions of any of these
laws.

         INTERSTATE BANKING AND BRANCHING. The Riegle-Neal Interstate Branching
Efficiency Act of 1994 ("IBBEA") authorizes interstate acquisitions of banks and
bank holding companies without geographic limitation beginning one year after
enactment. In addition, beginning June 1, 1997, IBBEA authorizes a bank to merge
with a bank in another state as long as neither of the states has opted out of
interstate branching between the date of enactment of IBBEA and May 31, 1997.
IBBEA further provides that states may enact laws permitting interstate bank
merger transactions prior to June 1, 1997. A bank may establish a de novo branch
in a state in which the bank does not maintain a branch if the state expressly
permits de novo branching. Once a bank has established branches in a state
through an interstate merger transaction, the bank may establish and acquire
additional branches at any location in the state where any bank involved in the
merger transaction could have established or acquired branches under applicable
federal or state law. A bank that has established a branch in a state through de
novo branching may establish and acquire additional branches in such state in
the same manner and to the same extent as a bank having a branch in such state
as a result of an interstate merger. If a state opts out of interstate branching
within the specified time period, no bank in any other state may establish a
branch in the opting out state, whether through an acquisition or de novo. On
August 28, 1995, Texas enacted legislation opting out of interstate branching.

         FDIC INSURANCE. The deposits of the Banks are insured by the FDIC. For
this protection, the Banks are subject to the rules and regulations of the FDIC.
The Banks also pay FDIC insurance premiums based on each Bank's annual
assessment rate assigned to it by the FDIC. The assessment rate is based on the
institution's capitalization risk category and "supervisory subgroup." An
institution's capitalization risk category is based on the FDIC's determination
of whether the institution is well capitalized, adequately capitalized or less
than adequately capitalized. An institution's supervisory subgroup is based on
the FDIC's assessment of the financial condition of the institution and the
probability that FDIC intervention or other corrective action will be required.
See page 17 under "non-interest expense" for the amount of FDIC premiums paid by
the Banks.


                                       6

         FDICIA REGULATION. On December 19, 1991, Congress enacted the Federal
Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), which
substantially revised the bank regulatory and funding provisions of the FDIA and
made revisions to several other federal banking statutes. Among other things,
FDICIA requires the federal banking regulators to take "prompt and corrective
action" in respect of depository institutions insured by the FDIC that do not
meet minimum capital requirements. FDICIA establishes five capital tiers: `"well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized," and "critically undercapitalized." As of December 31, 1998,
all of the Banks were classified as "well capitalized".

         FDICIA directs that each federal banking agency prescribe standards, by
regulation or guidelines, for depository institutions relating to internal
controls, information systems, internal audit systems, loan documentation,
credit underwriting, interest rate exposure, asset growth, compensation, asset
quality, earnings, stock valuation, and such other operational and managerial
standards as the agency deems appropriate. The FDIC, in consultation with the
other federal banking agencies, has adopted a final rule and guidelines with
respect to internal and external audit procedures and internal controls in order
to implement those provisions of FDICIA intended to facilitate the early
identification of problems in financial management of depository institutions.
On July 10, 1995, the federal banking agencies published the final rules
implementing three of the safety and soundness standards required by FDICIA,
including operational and managerial standards, asset quality and earnings
standards, and compensation standards.

         FDICIA also contains a variety of other provisions that may effect the
operations of the Company, including reporting requirements, regulatory
standards for real estate lending, "truth in savings" provisions, and the
requirement that a depository institution give ninety (90) days notice to
customers and regulatory authorities before closing any branch. The Federal
regulatory agencies have issued standards establishing loan-to-value limitations
on real estate lending.

         CAPITAL ADEQUACY GUIDELINES. The federal banking agencies have issued
guidelines for risk-based capital requirements. The guidelines are intended to
establish a systematic analytical framework that makes regulatory capital
requirements more sensitive to differences in risk profiles among banking
organizations, and takes off-balance sheet items into account in assessing
capital adequacy and minimizes disincentives to holding liquid, low-risk assets.
Under these guidelines, assets and credit equivalent amounts of off-balance
sheet items, such as letters of credit and outstanding loan commitments, are
assigned to one of several risk categories, which range from 0% for risk-free
assets, such as cash and certain U.S. government securities, to 100% for
relatively high-risk assets, such as loans, investments in fixed assets,
premises and other real estate owned. The aggregated dollar amount of each
category is then multiplied by the risk-weight associated with that category.
The resulting weighted values from each of the risk categories are then added
together to determine the total risk-weighted assets.

         The guidelines require a minimum ratio of qualifying total capital to
risk-weighted assets of 8%, of which at least 4% must consist of Tier 1 capital.
A banking organization's qualifying total capital consists of two components:
Tier 1 capital (core capital) and Tier 2 capital (supplementary capital). Tier 1
capital consists primarily of common stock, related surplus, retained earnings,
and qualifying preferred stock. Intangibles, such as goodwill, as well as the
unrealized gain or loss on available for sale securities, are generally deducted
from Tier 1 capital. At least 50% of the banking organization's total regulatory
capital must consist of Tier 1 capital. Tier 2 capital may consist of (i) the
allowance for possible loan and lease losses in an amount up to 1.25% of
risk-weighted assets; (ii) preferred stock not qualifying as Tier 1 capital plus
related surplus; and, (iii) mandatory convertible debt. The inclusions of the
foregoing elements of Tier 2 capital are subject to certain requirements and
limitations of the federal banking agencies. The federal banking agencies have
also adopted a minimum leverage ratio of Tier 1 capital to total assets of 3%
for banks that have a uniform composite ("CAMEL") rating of 1. All other
institutions and institutions experiencing or anticipating significant growth
are expected to maintain capital at least 100 to 200 basis points above the
minimum level. Furthermore, higher leverage ratios are required to be considered
well capitalized or adequately capitalized under the prompt corrective action
provisions of the FDICIA. See "Management's Discussion and Analysis- Capital
Resources."

         CRA AND FAIR LENDING DEVELOPMENTS. The Banks are subject to certain
fair lending requirements and reporting obligations involving home mortgage
lending operations and Community Reinvestment Act ("CRA") activities. The CRA
generally requires the federal banking agencies to evaluate the record of a
financial institution in meeting the credit needs of their local communities,
including low and moderate income neighborhoods. In addition to substantial
penalties and corrective measures that may be required for a violation of
certain fair lending laws, the federal banking agencies may take compliance with
such laws and CRA into account when regulating and supervising other activities.

         ENVIRONMENTAL LAWS. Under various federal, state and local laws,
ordinances and regulations, a current or previous owner, developer or operator
of real estate may be liable for the cost of removal or remediation of certain
hazardous or toxic substances at, on, under or in its property. The cost of such
removal or remediation of such substances can be substantial. These laws often
impose liability without regard to whether the owner or operator knew of, or was
responsible for, the release or presence of such substances. As a result, the
presence of such substances on any of the real property collateral securing any
of the Banks' loans may render such collateral less valuable or worthless or may
result in the Banks being unwilling to foreclose upon such collateral. In
addition, the Banks may incur substantial environmental liabilities and costs
from owning any collateral previously foreclosed upon that is later determined
to contain such substances. The Banks attempt to reduce this risk by making
inquiry with respect to environmental matters in connection with the extension
of credit; however, there can be no assurance that environmental liabilities do
not or will not exist with respect to the Banks' collateral.

EFFECT OF GOVERNMENTAL POLICIES AND RECENT LEGISLATION

         Banking is a business that depends on rate differentials. In general,
the difference between the interest rate paid by the Banks on their deposits and
other borrowings and the interest rate received by the Banks on loans extended
to their customers and securities held in the Banks portfolio comprise the major
portion of the Banks earnings. These rates are highly sensitive to many factors
that are beyond the control of the Banks. Accordingly, the earnings and growth
of the Banks are subject to the influence of local, domestic and foreign
economic conditions, including recession, unemployment and inflation.

         The commercial banking business is not only affected by general
economic conditions but is also influenced by the monetary and fiscal policies
of the federal government and the policies of regulatory agencies, particularly
the FRB. The FRB implements national monetary policies (with objectives such as
curbing inflation and combating recession) by its open-market operations in
United States Government securities, by adjusting the required level of reserves
for financial intermediaries subject to its reserve requirements and by varying
the discount rate applicable to borrowings by depository institutions. The
actions of the FRB in these areas influence the growth of bank loans,
investments and deposits and also affect the interest rates charged on loans and
paid on deposits. The nature and impact of any future changes in monetary
policies cannot be predicted.

         From time to time, legislation is enacted which has the effect of
increasing the cost of doing business, limiting or expanding permissible
activities or affecting the competitive balance between banks and other
financial intermediaries. Proposals to change the laws and regulations governing
the operations and taxation of banks, bank holding companies and other financial
intermediaries are frequently made in Congress, in the Texas legislature and
before various bank regulatory and other professional agencies. The likelihood
of any major changes and the impact such changes might have on the Company
and/or the Banks are impossible to predict. Certain of the potentially
significant changes which have been enacted and proposals which have been made
recently are discussed above.

DIVIDENDS

         Holders of Common Stock are entitled to receive dividends when, as and
if declared by the Company's Board of Directors out of funds legally available
therefore. The Company has not previously paid any dividends on the Common

the expansion and operation of its business. Accordingly, the Company does not
anticipate paying cash dividends on its Common Stock in the foreseeable future.
The payment of any future dividends will be at the discretion of the Company's
Board of Directors and will depend upon, among other things, future earnings,
capital requirements, the general financial condition of the Company, as well as
other relevant factors. The Company's principal source of funds to pay dividends
on the Common Stock is the cash dividends the Company receives from the Banks.
The payment of dividends by the Banks to the Company is subject to certain
restrictions imposed by federal banking laws, regulations and authorities.

ITEM 7.  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 1998 was $5.3 million, an increase of $424,000 or 8.7%
over the $4.9 million recorded in 1997 which was $1.1 million or 29.3% over
earnings of $3.8 million in 1996. Net income per diluted common share in 1998
was $1.14 compared with $1.02 in 1997 and $0.80 in 1996, an increase of 11.8%
and 27.5%, respectively. The Company's return on equity for 1998 was 10.24%
compared to 10.59% and 9.71% for 1997 and 1996, respectively. The decline in
1998 is primarily attributable to the purchase of $8.5 million of treasury stock
in 1998. The Company's return on assets for 1998 was 1.09% compared to 1.25% and
1.30% for 1997 and 1996, respectively. The decline of this ratio is primarily
attributable to the $95 million and $99 million increases in average assets for
1998 and 1997, respectively.

         1998 and 1997 earnings included a net $1.2 million and $.8 million
gain, respectively, on the sale of securities. Excluding these gains, net
operating earnings for 1998 were $4.1 million or $0.87 per diluted common share
and $4.1 million or $0.85 per diluted common share for 1997.

         Total assets of $512 million at December 31, 1998 grew $42 million or
9% over total assets of $470 million at December 31, 1997. Total loans at
December 31, 1998 were $192 million, 41% over the previous year end total of
$136 million. The growth in the loan portfolio was attained through internal
growth. Deposits reflect less dramatic growth, increasing 8% over the same
period to $448 million.

         The following table shows selected key performance ratios over the last
three years **:

</TABLE>

*    After adjustment to exclude unrealized gains and losses on available for 
     sale securities.

**   Restated to reflect the prior period adjustment, see Note 2 in the
     Consolidated Financial Statements

         The return on average assets ratio is calculated by dividing net income
by average total assets for the year. The return on average stockholders' equity
ratio is calculated by dividing net income by average stockholders' equity for
the year, excluding the effect of the net unrealized gain or loss on available
for sale securities. The average stockholders' equity to average total assets
ratio is calculated by dividing average stockholders' equity for the year by
average total assets for the year.

         PRIOR PERIOD ADJUSTMENT. The Company's financial statements as of
December 31, 1998, 1997 and 1996, have been restated to correct an error in the
application of the accounting method used for income tax accounting. The Company
has various net deferred tax assets made up primarily of the expected future tax
benefit of net operating loss carryforwards and reserves not yet deductible for
tax purposes. A valuation allowance was provided against these net deferred tax
assets upon the Company's emergence from bankruptcy in May 1992 when
"fresh-start" reporting was adopted. The benefits received from subsequent
reductions in the deferred tax asset valuation allowance were recorded as
reductions of current year income tax expense, which was inconsistent with
Financial Accounting Standard No. 109 and Statement of Position No. 90-7. The
benefits from the reductions have been restated as an increase in additional
paid-in capital as directed by the accounting pronouncements listed above. The 
restatement does have the effect of reducing reported net income while 
increasing additional paid-in capital in an amount equal to the decrease in 
retained earnings. It has no effect upon the cash on hand, book value, cash 
flow, the amount of the tax loss carryforward, or the amount of taxes due or 
owing.

The effect of the restatement is as follows:

</TABLE>


         NET INTEREST INCOME. Net interest income constitutes the principal
source of income for the Company and represents the difference between interest
income on earning assets and interest expense on interest-bearing liabilities.
The largest category of earning assets for 1998 and 1997 was investment
securities with the second largest being loans. Net interest income for 1998 was
$18.1 million, an increase of $2.5 million or 16.0% compared to $15.6 million in
1997. The net increase reflected a $5.7 million increase in interest income that
was offset by a $3.2 million increase in interest expense. The interest income
increase was due primarily to an increase in the investment security and loan
portfolios. Average investment securities and average loans in 1998 increased
18.5% and 33.7%, respectively, over 1997. The Company's yield on earning assets
decreased to 7.72% in 1998 from 7.74% in 1997. The rate paid on interest bearing
liabilities decreased one basis point from 4.09% in 1997 to 4.08% in 1998. The
net interest margin is the net effective yield on earning assets, calculated as
net interest income on a taxable-equivalent basis expressed as a percentage of
average total earning assets. The net interest margin for 1998 was 4.24%
compared to 4.42% and 4.80% for 1997 and 1996, respectively. The decrease in the
net interest margin for 1998 is reflective of higher volumes of earning assets.
The net interest spread decreased one basis point to 3.64% in 1998 from 3.65% in
1997.

         The following table analyzes the increases in taxable-equivalent net
interest income stemming from changes in interest rates and from asset and
liability volume, including mix, for the years ended December 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 in
proportion to the absolute amounts of change in each.

          INTEREST RATE SENSITIVITY. The Company continuously monitors and
manages the balance between interest rate-sensitive assets and liabilities.
Management seeks to maintain consistent growth of net interest income through
periods of changing interest rates by avoiding fluctuating net interest margins
and to maintain consistent growth of net interest income through periods of
changing interest rates.

         Interest rate sensitivity is the relationship between changes in market
interest rates and changes in net interest income due to repricing
characteristics of assets and liabilities.

         The following table commonly referred to as a "static gap report,"
indicates the Company's interest rate sensitivity position at December 31, 1998
and may not be reflective of positions in subsequent periods:

         The interest rate sensitivity table reflects that the Company is
liability sensitive, on a cumulative basis, 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 $1,314,000 or 30% increase in non-interest income for 1998 from
1997 is due primarily to the $679,000 increase in net trading profits and the
$444,000 increase in service charges and fees. The improvement in service
charges and fees can be partly attributed to a 21% increase in average
transaction deposit accounts in 1998. Included in 1998 is non-recurring income
of $1,894,000 due to net gains on other real estate owned and investment
securities which was higher than the $1,195,000 reported in 1997. Therefore, the
increase in 1998, disregarding the non-recurring items, would be $615,000 or
19.3% higher than 1997.

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

</TABLE>

         Non-interest expense of $15.3 million for the year ended 1998
represented an increase of 24.7% compared with 1997. However, as a percentage of
average assets, non-interest expense remained stable at 3.15% in 1998 compared
to 1997. The increase in non-interest expense is reflected in occupancy and
equipment expenses and salaries and benefit expense. The 27.4% increase in
salaries and benefits for 1998 is due to the (i) addition of employees from the
acquisitions of the three Wells Fargo branches of which only five months was
included in 1997, (ii) two new branches that were opened in 1998, and (iii)
full-time equivalent employees increased by 39 people from 210 in 1997 to 249 at
December 31, 1998. The $649,000 or 33.9% increase in occupancy and equipment
expenses is due to the depreciation expense related to the three buildings
acquired in the Wells Fargo branch acquisitions, the two new branches opened in
1998 in San Marcos and South Laredo, and installation of computer networks at
the new locations. Goodwill expense increased $185,000 or 96.9% due to the Wells
Fargo acquisition in July 1997.

         INCOME TAXES. The Company recognized income tax expense of $3.1 million
in 1998 compared to $2.8 million in 1997. See Note 15 to the Consolidated
Financial Statements for details of tax expense. At December 31, 1998, the
Company had approximately $95 million in net operating loss carryforwards that
will be available to reduce income tax liabilities in future years. If unused,
approximately $91 million of such carryforwards will expire in 2005, with the
remaining approximately $4 million expiring in 2006. The preconfirmation net
operating loss carryforwards arose from the Company's emergence from bankruptcy
in May 1992.

         INVESTMENT SECURITIES. Total investment securities averaged $236.4
million in 1998, an 18% increase over the 1997 average of $199.5 million. The

December 31, 1998, by stated maturity with the weighted average interest yield

         ALLOWANCE FOR POSSIBLE LOAN LOSSES. The allowance for possible 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 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 possible loan losses. Loans
identified as losses by management, external loan review or bank examiners are
charged-off.

         The Company recorded a $232,000 provision for possible loan losses
during 1998, compared to $80,000 recorded during 1997. The provision is
reflective of the growth in the loan portfolio. Despite loan growth in 1996, a
credit to the provision for loan losses of $5,000 was made to reduce the
allowance for loan losses to an appropriate level. Credits to the provision for
loan losses were also made in 1995 and 1994 in the amounts of $855,000 and
$990,000, respectively. The aggregate total of credits made to the provision for
loan losses since the 1992 reorganization amounts to $5,680,000 and was a
significant contribution to the improved capitalization of the Company. The
improvement in credit quality of the loan portfolio and recoveries of previously
charged-off loans that provided unanticipated additions to the allowance for
possible loan losses justify the credits made to the allowance. The Company
recorded net charge-offs of $20,000 for the year ended December 31, 1998
compared to net charge-offs of $30,000 for 1997.

The following table summarizes, for the periods presented, the activity in the
allowance for possible loan losses arising from provisions credited to
operations, loans charged off and recoveries of loans previously charged off:

         Allocation of a portion of the allowance does not preclude its
availability to absorb losses in other categories. The allocation is determined
by providing specific reserves against each criticized loan plus an unallocated
portion against the remaining portfolio based on experience factors.

         NON-PERFORMING ASSETS. Non-performing assets increased 32.1% to
$2,094,000 at December 31, 1998, compared with $1,585,000 at December 31, 1997,
$1,910,000 at December 31, 1996, $2,065,000 at December 31, 1995 and $1,805,000
at December 31, 1994. Non-performing assets as a percentage of total assets
increased to .41% at December 31, 1998 up from .34% one year ago. This increase
in non-performing assets is due to real estate assets being foreclosed on at a
certain Bank.

         Non-performing assets consist of non-accrual loans, restructured 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 90
days or more past due. All installment loans past due 90 days or more are
classified as 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.

         Restructured loans are loans on which the interest and/or the principal
has been reduced due to deterioration in the borrower's financial condition.
Even though these loans are performing, they are included in non-performing
assets because of the loss of revenue related to the reduction in interest
and/or principal.

         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 possible loan losses. Any future
write-downs, expenses related to the property, and any gain or loss resulting
from the sale of the property are charged to operations.

respectively.

         Independent third party loan reviews of the 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' of each Bank reviews
new loans, renewals and delinquencies. Management of each Bank monitors, on a
continuing basis, loans which it feels should be followed closely. The Banks are
required by the regulatory authorities to have foreclosed real estate appraised
periodically.

         DEPOSITS. The primary source of funds for the Company is the deposits
of the Banks. The Company does not accept brokered deposits. The following table

         Total average deposits increased $86 million or 25.5% due to internal
growth. Mexico is part of the natural trade territory of the Banks. Thus,
dollar-denominated deposits from Mexican sources have traditionally been a
significant source of deposits. Included in total deposits are $103,768,000,
$94,477,000, and $83,677,000 of Mexican National deposits at December 31, 1998,
1997, and 1996, respectively (in United States dollars only).

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, trading account securities 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 77.9% of total deposits at December 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.

         Net cash provided by operating activities at December 31, 1998,
includes a $4.9 million decrease in investment securities held in a trading
account. See Note 1 of the Consolidated Financial Statements for the accounting
treatment of a trading account.

         At December 31, 1998, the Company's liquid assets amounted to $199
million or 39% of total gross assets, down from $201 million or 43% at December
31, 1997. Secondary sources of liquidity include the Company's ability to sell
loan participations and purchase federal funds. In addition, NBC-Eagle Pass has
an approved federal funds line at a correspondent bank and NBC-Laredo has an
approved line of credit with the Federal Home Loan Bank.

CAPITAL RESOURCES

          Total stockholders' equity increased $1.1 million to $52.2 million at
December 31, 1998 from $51.1 million at December 31, 1997. In addition to net
income of $5.3 million, stockholders' equity increased $2.9 million due to the
reduction in the deferred tax asset valuation allowance and $1.4 million due to
an improvement in the net fair value of securities available for sale.
Stockholders' equity was reduced by the 463,675 shares of common stock
repurchased at a cost of $8.5 million, or an average of $18.35 per share, as
part of a stock repurchase plan approved by the Board of Directors in 1997. The
Board had authorized the repurchase of 500,000 shares. As of March 23, 1999, the
Company has repurchased 494,674 shares. The ratio of total stockholders' equity
to total assets was 10.2% at December 31, 1998 compared with 10.9% at December
31, 1997.

         The Company and the Banks are subject to minimum capital ratios
mandated by their respective banking industry regulators. The table in Note 19
in the Consolidated Financial Statements illustrates the Company's and the
Banks' compliance with the risk-based capital guidelines of the FRB and the 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 at December 31, 1998 include unfunded loan commitments
and letters of credit. Pursuant to the current 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 quarterly average total assets. A leverage ratio of
3.0% 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 for the Company 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 minimum ratio for qualifying total
capital is 8.0% of which 4.0% must be Tier 1 capital. For the Company's capital
ratios at December 31, 1998 and 1997, see Note 19 in the Consolidated Financial
Statements.

ACCOUNTING MATTERS

         In June 1997, the Financial Accounting Standards Board issued SFAS No.
130, "Reporting Comprehensive Income." The statement provides that all items
that are required to be recognized under accounting standards as


                                       24
<PAGE>   25

comprehensive income be reported in a financial statement that is displayed with
the same prominence as other financial statements. Comprehensive income includes
net income as well as certain items that are reported directly within a separate
component of stockholders' equity and bypass net income. The provisions of SFAS
No. 130 are effective for fiscal years beginning after December 15, 1997. The
adoption of this statement did not have a material impact on financial position
or results of operations.

         In June 1997, the Financial Accounting Standards Board issued SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 establishes standards for the way that public business enterprises
report information about operation segments in annual financial statements and
requires that those enterprises report selected information about operation
segments in interim financial reports issued to shareholders. SFAS No. 131 also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. SFAS No. 131 is effective for financial
statements for periods beginning after December 15, 1997. The adoption of this
statement did not have an impact on financial position or results of operation.

         SFAS No. 128 "Earnings Per Share", issued in February 1997, and
effective December 31, 1997, establishes standards for computing and presenting
earnings per share ("EPS") and applies to entities with publicly held common
stock or potential common stock. This statement simplifies the standards for
computing earnings per share previously found in APB Opinion No. 15, Earnings
per Share, and makes them comparable to international EPS standards. It replaces
the presentation of primary EPS with a presentation of basic EPS. It also
requires dual presentation of basic and diluted EPS on the face of the income
statement for all entities with complex capital structures and requires a
reconciliation of the numerator and denominator of the basic EPS computation to
the numerator and denominator of the diluted EPS computation. Basic EPS excludes
dilution and is computed by dividing income available to common stockholders by
the weighted-average number of common shares outstanding for the period. Diluted
EPS reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock that then shared in the earnings of the
entity. Diluted EPS is computed similarly to fully diluted EPS pursuant to
Opinion No.15.

         In June 1998, the Financial Accounting Standards Board issued Statement
No. 133, "Accounting for Derivative Instruments and Hedging Activities", which
is required to be adopted in years beginning after June 15, 1999. The Company
expects to adopt the new Statement effective January 1, 2000. The Statement will
require the Company to recognize all derivatives on the balance sheet at fair
value. Derivatives that are not hedges must be adjusted to fair value through
income. If the derivative is a hedge, depending on the nature of the hedge,
changes in the fair value of derivatives will either be offset against the
change in fair value of the hedged assets, liabilities, or firm commitments
through earnings or recognized in other comprehensive income until the hedged
item is recognized in earnings. The ineffective portion of a derivative's change
in fair value will be immediately recognized in earnings. Because of the
Company's minimal use of derivatives, management does not anticipate that the
adoption of the new Statement will have a significant effect on the Company's
earnings or financial position.

YEAR 2000

         The Year 2000 (Y2K) issue centers on the inability of computer systems
to recognize the year 2000. Many existing computer programs and systems were
originally programmed with six digit dates that provided only two digits to
identify the calendar year in the date field, without considering the upcoming
change in the century. With the impending millennium, these programs and
computers will recognize "00" as the year 1900 rather that the year 2000.

         The Company has formed a Y2K project team comprising technological,
data processing, and operations personnel from each of the Banks' management.
The project team has developed and is currently executing a planned review and
risk assessment of all technology items used in the Company's operations,
including core data processing systems, as well as material relationships with
suppliers, correspondents, and customer groups. The identification of critical
items and relations, and the renovation or replacement of items which are
non-compliant with current guidelines were complete in 1998 in accordance with
regulatory agency guidelines. Y2K compliance will be effected through data
processing hardware and software upgrades and purchases of new equipment with an
estimated aggregate cost of approximately $573,000. Approximately $80,000 was
expensed for the year ended December 31, 1998 for the Y2K project.

         The three core systems, or mission critical systems, were implemented
and tested for Y2K compliance in December 1998. These three systems include the
deposit and loan systems, any ancillary or interface programs and the imaging
software. The ATM software and the NT Server software will both be upgraded and
tested by the end of the second quarter of 1999.


                                       25
<PAGE>   26

         The Company has initiated formal communications with all of its
significant suppliers to determine the extent to which the Company is vulnerable
to those third parties' failure to remediate their own Y2K issue. The Company
presently believes that with modifications to existing software and conversions
to new software, the Y2K issue will be mitigated without causing a material
adverse impact on the operations of the Company. However, if such modifications
and conversions are not made, or are not completed timely, the Y2K issue could
have an impact on the operations of the Company. At this time, management does
not believe that the impact and any resulting costs will be material.

                          INDEPENDENT AUDITORS' REPORT



To the Board of Directors and Stockholders
National Bancshares Corporation of Texas and Subsidiaries
San Antonio, Texas


We have audited the accompanying consolidated balance sheets of National
Bancshares Corporation of Texas and Subsidiaries as of December 31, 1998 and
1997, and the related consolidated statements of income, changes in
stockholders' equity, and cash flows for the years ended December 31, 1998,
1997, and 1996. These consolidated financial statements are the responsibility
of the Company'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 audits to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of National Bancshares
Corporation of Texas and Subsidiaries as of December 31, 1998 and 1997, and the
results of operations and its cash flows for the years ended December 31, 1998,
1997, and 1996, in conformity with generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, such statements
have been restated to correct the method of accounting for income taxes pursuant
to the principles of fresh-start accounting contained in Statement of Position
90-7 of the American Institute of Certified Public Accountants.

                  NATIONAL BANCSHARES OF TEXAS AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of National Bancshares Corporation of
     Texas (the Company) and its wholly-owned subsidiaries conform to generally
     accepted accounting principles and to general practices within the banking
     industry. The preparation of consolidated 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 consolidated financial statements and the
     reported amounts of revenues and expenses during the reporting period.
     Actual results could differ from those estimates. Following is a summary of
     the Company's more significant accounting and reporting policies:

     NATURE OF OPERATIONS

     The Company is a bank holding company which operates four commercial banks
     and seven branches located in Central Texas and South Texas on the
     Texas-Mexico border.

     CONSOLIDATION

     The consolidated financial statements include the accounts of National
     Bancshares Corporation of Texas and its wholly-owned subsidiary, NBT of
     Delaware, Inc. (the Delaware Company) and the accounts of the Delaware
     Company's wholly-owned subsidiaries, NBC Bank, N.A. (Eagle Pass), NBC Bank
     Laredo, N.A. (Laredo), NBC Bank (Rockdale), NBC Bank-Central, N.A.
     (Luling), and NBC-Holdings-Texas, Inc., collectively referred to as the
     "Banks." Significant intercompany accounts and transactions have been
     eliminated in consolidation.

     INVESTMENTS IN SECURITIES

     Securities held principally for resale in the near term are classified as
     trading securities and recorded at their fair values. Unrealized gains and
     losses on trading securities are included in other income. Bonds, notes,
     and debentures for which the Company has the positive intent and ability to
     hold to maturity are reported at cost adjusted for amortization of premiums
     and accretion of discounts, which are recognized in interest income using
     the interest method over the period to maturity. Securities available for
     sale consist of bonds, notes, and debentures not classified as trading
     securities nor as securities to be held to maturity. These securities are
     recorded at their fair values. Unrealized holding gains and losses, net of
     tax, on securities for sale are reported as a net amount in a separate
     component of stockholders' equity.

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

     Gains and losses on the sale of securities available for sale are
     determined using the specific-identification method with the exception of
     the investment portfolio maintained at NBT of Delaware, Inc. in which the
     average cost method is used to compute gains and losses on sales. The
     transfer of a security between categories of investments is accounted for
     at fair value.

     ALLOWANCE FOR POSSIBLE LOAN LOSSES

     The allowance is maintained at a level considered adequate by management to
     absorb probable losses. Management determines the adequacy of the allowance
     based upon reviews of individual loans, recent loss experience, current
     economic conditions, the risk characteristics of the various categories of
     loans, and other pertinent factors. In addition, various regulatory
     agencies, as an integral part of their examination process, periodically
     review the Banks allowances for possible loan losses. Loans deemed
     uncollectible are charged to the allowance. The allowance is increased by
     provisions charged to operating expense and recoveries on loans previously
     charged off.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     Impaired loans are measured based on (1) the present value of expected
     future cash flows discounted at the loan's effective interest rate; (2) the
     loan's observable market price; or (3) the fair value of the collateral if
     the loan is collateral dependent.

     BANK PREMISES AND EQUIPMENT

     Land is carried at cost. Bank premises and equipment are stated at cost,
     net of accumulated depreciation. Depreciation is recognized on
     straight-line and accelerated methods over the estimated useful lives of
     the assets. The estimated useful lives range from 3 to 50 years.
     Amortization of leasehold improvements is computed using the straight-line
     method over the primary term of the lease.

     INTEREST INCOME ON LOANS

     Unearned income on discounted loans is credited to the unearned discount
     account when the loan is made and is recorded as interest income over the
     term of the loan under the sum-of-the-digits (Rule of 78's) method. Income
     recognized under the sum-of-the-digits method is not materially different
     than income that would be recognized under the level yield or "interest
     method."

     Interest on other loans is accrued and credited to income based on the
     principal amount outstanding. Generally, the accrual of interest on
     impaired loans is discontinued when principal or interest payments become
     90 days past due, and/or in the opinion of management, there is an
     indication that the borrower may be unable to meet payments as they become
     due. Upon such discontinuance, all unpaid accrued interest is reversed and
     charged to current year operations. Interest income is subsequently
     recognized only to the extent cash payments are received.

     LOAN ORIGINATION FEES AND COSTS

     Loan origination fees and certain direct origination costs are deferred and
     recognized as an adjustment of the yield over the contractual term of the
     related loan.

     OTHER REAL ESTATE OWNED

     Real estate acquired by foreclosure is carried in other assets at the lower
     of the recorded investment in the property or the fair value of the
     property less estimated selling costs. Prior to foreclosure, the value of
     the underlying loan is written down to the fair value of the real estate to
     be acquired by a charge to the allowance for loan losses, if necessary. Any
     subsequent write-downs are charged against operating expenses. Operating
     expenses of such properties, net of related income, are included in other
     expenses.

     INTANGIBLE ASSETS

     The excess cost over fair value of net assets of businesses acquired
     (goodwill) is amortized on a straight-line basis over twenty-five years.
     Intangible assets are included in other assets. All such intangible assets
     are periodically evaluated as to the recoverability of their carrying
     value.

     INCOME TAXES

     The Company and its subsidiaries file an income tax return on a
     consolidated basis. Provisions for income taxes are based on taxes payable
     or refundable for the current year (after exclusion of nontaxable income
     such as interest on state and municipal securities) and deferred taxes on
     temporary differences between the amount of taxable income and pretax
     financial income and between the tax bases of assets and liabilities and
     their reported amounts in the consolidated financial statements. Deferred
     tax assets and liabilities are included in the consolidated financial
     statements at currently 


                                       33

                  NATIONAL BANCSHARES OF TEXAS AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     enacted income tax rates applicable to the period in which the deferred
     tax assets and liabilities are expected to be realized or settled as 
     prescribed in SFAS No. 109, "Accounting for Income Taxes." As changes in
     tax laws or rates are enacted, deferred tax assets and liabilities are
     adjusted through the provisions for income taxes.

     Deferred income taxes are provided for the temporary differences between
     the financial reporting basis and the tax basis of the Company's assets and
     liabilities. In accordance with AICPA Statement of Position (SOP) No. 90-7,
     income tax benefits recognized from preconfirmation net operating loss
     carryforwards were used first to reduce reorganization value in excess of
     amounts allocable to identifiable assets and thereafter to increase
     additional paid-in capital (See Note 15).


     CASH AND CASH EQUIVALENTS

     For the purpose of presentation in the consolidated statements of cash
     flows, cash and cash equivalents are defined as those amounts included in
     the consolidated balance sheet caption "cash and due from banks."

     OFF-BALANCE-SHEET FINANCIAL INSTRUMENTS

     In the ordinary course of business, the subsidiary Banks have entered into
     off-balance-sheet financial instruments consisting of commitments to extend
     credit and standby letters of credit. Such financial instruments are
     recorded in the consolidated financial statements when they are funded or
     related fees are incurred or received.

     The Company or its subsidiaries are not a party to any off-balance-sheet
     derivative financial instruments such as interest rate futures or swap
     contracts.

     NET INCOME PER SHARE OF COMMON STOCK

     The Company has adopted Statement of Financial Accounting Standards No.
     128, "Earnings Per Share", (SFAS No. 128) effective December 31, 1997. This
     Statement requires the computation and presentation of both "basic" and
     "diluted" earnings per share for all companies with complex capital
     structures.

     Basic earnings per share excludes dilution and is computed by dividing
     income available to common stockholders by the weighted-average number of
     common shares outstanding for the period. Diluted earnings per share
     reflects the potential dilution that could occur if securities or other
     contracts to issue common stock were exercised or converted into common
     stock or resulted in the issuance of common stock that then shared in the
     earnings of the entity.

     COMPREHENSIVE INCOME

     The Company has adopted Statement of Financial Accounting Standards No.
     130, "Reporting Comprehensive Income" (SFAS No. 130). SFAS No. 130
     establishes standards for reporting and display of comprehensive income and
     its components (revenues, expenses, gains, and losses) in a full set of
     general-purpose financial statements. SFAS No. 130 requires that an
     enterprise (a) classify items of other comprehensive income by their nature
     in a financial statement and (b) display the accumulated balance of other
     comprehensive income separately from retained earnings and additional
     paid-in capital in the equity section of a statement of financial position.
     Adoption of this statement did not have a material impact on the Company's
     financial position, results of operations or liquidity.

     SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION

     The Company has adopted Statement of Financial Accounting Standards No.
     131, "Disclosures about Segments of an Enterprise and Related Information"
     (SFAS No. 131). SFAS No. 131 establishes standards for the way that public
     business enterprises report information about operation segments in annual
     financial statements and requires that those enterprises report selected
     information about operation segments in interim financial reports issued to
     shareholders. 


                                       34

                  NATIONAL BANCSHARES OF TEXAS AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     SFAS No. 131 also establishes standards for related disclosures about
     products and services, geographic areas, and major customers. The adoption
     of this statement did not have an impact on financial position or results
     of operations.

     RECLASSIFICATIONS

     Certain amounts have been reclassified from prior presentations at December
     31, 1997 and 1996 to conform to classifications at December 31, 1998. There
     is no effect on previously reported net income or retained earnings.

2.   PRIOR PERIOD ADJUSTMENT

     The Company's financial statements as of December 31, 1998, 1997 and 1996,
     have been restated to correct an error in the application of the accounting
     method used for income tax accounting. The Company has various net deferred
     tax assets made up primarily of the expected future tax benefit of net
     operating loss carryforwards and reserves not yet deductible for tax
     purposes. A valuation allowance was provided against these net deferred tax
     assets upon the Company's emergence from bankruptcy in May 1992 when
     "fresh-start" reporting was adopted. The benefits received from subsequent
     reductions in the deferred tax asset valuation allowance were recorded as
     reductions of current year income tax expense, which was inconsistent with
     Financial Accounting Standard No. 109 and Statement of Position No. 90-7.
     The benefits from the reductions have been restated as an increase in
     additional paid-in capital as directed by the accounting pronouncements
     listed above. The restatement does have the effect of reducing reported net
     income while increasing additional paid-in capital in an amount equal to
     the decrease in retained earnings. It has no effect upon the cash on hand,
     book value, cash flow, the amount of the tax loss carryforward, or the
     amount of taxes due or owing.

     The effect of the restatement is as follows:

     The restoration of loan loss provision of $5,000 for the year ended
     December 31, 1996 resulted from significant collections of previously
     charged-off loans, and from improved performance and quality of the loan
     portfolio.

     Impaired loans are those loans where it is probable that all amounts due
     according to contractual terms of the loan agreement will not be collected.
     The Company has identified these loans through its normal loan review
     procedures. Impaired loans include (1) all non-accrual loans, (2) loans
     which are 90 days or more past due, unless they are well secured (i.e. the
     collateral value is sufficient to cover principal and accrued interest) and
     are in the process of collection, and (3) other loans which management
     believes are impaired. Substantially all of the Company's impaired loans
     are measured at the fair value of the collateral. In limited cases the
     Company may use other methods to determine the level of impairment of a
     loan if such loan is not collateral dependent.

     As of December 31, 1998, 1997, and 1996, the Banks have impaired loans of
     $899,000, $1,314,000, and $1,195,000, respectively. The allowance for loan
     losses related to those loans was $75,000, $117,000, and $97,300 at
     December 31, 1998, 1997, and 1996, respectively. The average recorded
     investment in impaired loans during the year ended December 31, 1998, 1997,
     and 1996 was $1,546,000, $1,254,000, and $1,186,000, respectively. Interest
     income of approximately $50,000, $287,000, and $478,000 on impaired loans
     was recognized for cash payments received during the year ended December
     31, 1998, 1997, and 1996, respectively. Management of the Company
     recognizes the risks

     associated with these impaired loans. However, management's decision to
     place loans in this category does not necessarily mean that the Company
     expects losses to occur.

     The Banks' nonperforming loans at December 31, 1998 consisted of $311,000
     in accruing loans over 90 days past due and $899,000 in nonaccrual loans.
     The reduction in interest income associated with nonaccrual loans during
     the year ended December 31, 1998, 1997, and 1996 was approximately
     $185,000, $151,000, and $187,000, respectively.

10.  COMMITMENTS AND CONTINGENT LIABILITIES

     The Company's consolidated financial statements do not reflect various
     commitments and contingent liabilities which arise in the normal course of
     business and which involve elements of credit risk, interest rate risk, and
     liquidity risk. These commitments and contingent liabilities are described
     in Note 17 as financial instruments with off-balance sheet risk.

     The Company and its wholly owned subsidiaries are defendants in legal
     actions arising from normal business activities. Management believes that
     those actions are without merit or that the ultimate liability, if any,
     resulting from them will not materially affect the Company's financial
     position, results of operations, cash flows, or liquidity.

     The Company has a forty-two month sub-lease agreement for general corporate
     office space. The commencement date of the sub-lease was July 1, 1996. The
     Company also leases property which is used as a data processing center. The
     commencement date of this lease was October 1, 1995. This lease expires on
     March 31, 1999. The Company also entered into a twelve month lease for a
     loan production office which expired on January 31, 1999. Gross rental
     expense for the year ended December 31, 1998, 1997, and 1996 was $134,738,
     $108,458, and $76,040, respectively.

     Future minimum lease payments at December 31, 1998 are as follows:

11.  EARNINGS PER SHARE

     In 1997, The Financial Standards Board issued Statement No. 128, "Earnings
     Per Share." Statement 128 replaced the calculation of primary and fully
     diluted earnings per share. Unlike primary earnings per share, basic
     earnings per share excludes any dilutive effects of options, warrants and
     convertible securities. Diluted earnings per share is very similar to the
     previously reported fully diluted earnings per share. All earnings per
     share amounts for all periods have been presented, and where appropriate,
     restated to conform to the Statement No. 128 requirements.

     Basic earnings per share is computed by dividing net income for the year by
     the weighted average number of shares outstanding.

     Diluted earnings per share is determined by dividing net income for the
     year by the weighted average number of shares of common stock and common
     stock equivalents outstanding. Common stock equivalents assume exercise of
     stock options and use of proceeds to purchase treasury stock at the average
     market price for the period.

12.  EMPLOYEE BENEFITS

     The Company has a defined contribution plan for the benefit of
     substantially all employees. The plan includes a 401(k) retirement plan
     feature. Employees are allowed to make contributions to the plan. Each
     subsidiary Bank's contribution to the plan is determined annually by that
     Bank's Board of Directors. Plan expense for the years ended December 31,
     1998, 1997 and 1996 totaled $140,767, $104,873, and $49,515, respectively.

13.  MANAGEMENT AND DIRECTOR STOCK OPTION PLAN

     Effective March 31, 1994, the Company adopted the 1994 Nonqualified Stock
     Option Plan (the 1994 Plan). Options representing 80,000 shares available
     under the 1992 Plan were transferred to the 1994 Plan. In addition, 8,334
     shares representing unexercised options under the 1992 Plan of an officer
     who resigned, were added to the 1994 Plan. The maximum number of shares for
     which the options could be granted and sold under the 1994 Plan was 88,334
     shares of Common Stock.

     The 1994 Plan shall be administered by the Board of Directors of the
     Company, or an administrator designated by the Board of Directors. The
     Board of Directors or the administrator is authorized to determine the
     terms and conditions of all options granted. The Board of Directors or the
     applicable administrator may adopt such rules and regulations for carrying
     out the 1994 Plan as it may deem best.

     Each option under the 1994 Plan shall terminate and be unexercisable upon
     the date specified by the applicable administrator, however, this date
     shall not exceed ten years from the grant date of the options.

     In 1994, options representing 29,000 shares included in the 1994 Plan were
     granted to certain officers and employees of the Company at an option price
     of $5.68 per share. The grant date of these options is March 31, 1994, with
     a vesting period of 20% per year for five years. In 1998 and 1996, 2,500
     and 1,200 of these options were exercised, respectively. None of these
     granted options were exercised in 1997, 1995 or 1994. At December 31, 1994,
     there were 59,334 shares as to which options could be granted in the future
     under the 1994 Plan.

     Effective March 1, 1995, the Company adopted the 1995 Stock Option Plan
     (the 1995 Plan), which includes the "Outside Director's Stock Option
     Agreement" and the "Nonqualified Stock Option Agreement." The maximum
     number of shares for which options could be granted or sold under the 1995
     Plan was 214,000 shares of Common Stock. This number is limited by the
     29,000 options which were granted under the 1994 Plan. Shares of Common
     Stock subject to options which for any reason expire or terminate
     unexercised, and shares which are reacquired by the Company after

     issuance under the 1995 Plan, may again be available for grant or purchase
     under the 1995 Plan. The number of shares of Common Stock available for
     issuance under the 1995 Plan are subject to adjustment in the event of
     certain corporate transactions, including stock dividends, mergers,
     recapitalizations, or similar events.

     In 1998, options representing 40,850 shares were granted to certain
     officers and directors of the Company at an option price of $13.25 per
     share, after the approval of 230,000 additional shares of common stock
     being added to the 1995 plan. Also in 1998, 850 shares included in the 1995
     plan were reacquired by the Company.

     In 1997, options representing 50,000 shares were granted to certain
     officers and directors of the Company at an option price of $13.25 per
     share. In 1996, options representing 1,800 shares included in the 1995 plan
     were reacquired by the Company. On March 1, 1996, options representing
     14,000 shares were granted to the outside directors of the Company at an
     option price of $11.25 per share. On September 30, 1996, options
     representing 5,700 shares were granted to certain officers of the Company
     at an option price of $11.00 per share. In 1995, options representing
     103,000 shares included in the 1995 Plan were granted to certain directors
     and officers of the Company at an option price of $6.25 per share. The
     grant date of these options is March 1, 1995. Under the "Outside Director's
     Stock Option Agreement," the outside director shall have a right to
     exercise the option at any time after the date of grant or the date the
     Company's shareholders approve the 1995 Plan, whichever is later, but the
     option may not be exercised, in whole or in part, after the seventh
     anniversary of the date of grant. Under the "Nonqualified Stock Option
     Agreement," options are exercisable in one-fifth increments commencing one
     year after the grant date and subject to any longer or shorter periods the
     Administrator may impose. The option, however, may not be exercised, in
     whole or in part, after five years from the date of grant.

     At December 31, 1998, there were 204,100 shares available for future grants
     under the 1995 Plan.

     Effective January 1, 1996, the Company adopted the disclosure provisions of
     SFAS No. 123, "Accounting for Stock-Based Compensation," however, the
     Company will continue to account for stock-based compensation using APB
     Opinion No. 25 for both stock option plans and, accordingly, no
     compensation cost will be recognized for stock options in the consolidated
     financial statements. In determining compensation cost based on the fair
     value method at the date of grant for stock options under SFAS No. 123, the
     Company's net income and net income per share would have been reduced by
     less than 1% for 1998, 1997, and 1996.

</TABLE>


     For federal income tax purposes, the Company had approximately $95 million
     in net operating loss carryforwards as of December 31, 1998 which will be
     available to reduce income tax liabilities in future years. The
     preconfirmation net operating loss carryforwards arose from the Company's
     emergence from a reorganization under Chapter 11 of the United States
     Bankruptcy Code in May 1992. If unused, approximately $91 million of such
     carryforwards will expire in 2005, with the remaining approximately $4
     million expiring in 2006.

     Pursuant to SFAS No. 109, the Company had available certain deductible
     temporary differences and net operating loss carryforwards for use in
     future tax reporting periods, which created deferred tax assets. SFAS No.
     109, requires that deferred tax assets be reduced by a valuation allowance
     if, based on the weight of the available evidence, it is more likely than
     not that some portion or all of the deferred tax assets will not be
     realized. During the year ended December 31, 1998 and 1997, the deferred
     tax asset valuation allowance was reduced by $2,873,000 and $2,611,000,
     respectively, to adjust the recorded net deferred tax asset to an amount
     considered more likely than not to be realized. The deferred tax asset net
     of the valuation allowance and recorded on the books of the Company was
     $900,000 at December 31, 1998. Realization of this asset is dependent on
     generating sufficient taxable income prior to the expiration of the loss
     carryforwards. Realization could also be affected by a significant
     ownership change of the Company over a period of three years as prescribed
     by income tax law. Although realization of the net deferred tax asset is
     not assured because of these uncertainties, management believes it is more
     likely than not that all of the recorded deferred tax asset will be
     realized.

     In accordance with AICPA SOP No. 90-7, "Financial Reporting by Entities in
     Reorganization Under the Bankruptcy Code", income tax benefits recognized
     from preconfirmation net operating loss carryforwards and other tax assets
     are used first to reduce the reorganization value in excess of amounts
     allocable to identifiable assets and then to increase additional paid-in
     capital.

16.  RELATED PARTY TRANSACTIONS

     The Banks have entered into transactions with their directors, executive
     officers, and their affiliates. Such transactions were made in the ordinary
     course of business on substantially the same terms and conditions,
     including interest rates and collateral, as those prevailing at the same
     time for comparable transactions with other customers, and did not, in the
     opinion of management, involve more than normal credit risk or present
     other unfavorable features. The aggregate amount of loans to such related
     parties at December 31, 1998 and 1997 was $5,906,000 and $4,203,000,
     respectively. During the year ended December 31, 1998 and 1997, new loans
     to such related parties amounted to $2,884,000 and $1,405,000,
     respectively, and repayments amounted to $1,181,000 and $904,000,
     respectively. No outside directors of the Company have any outstanding
     loans.

     During 1998 and 1997, the Company utilized a stock brokerage firm, which is
     100% owned by the Company's Chairman, to execute certain transactions on
     its behalf. The Company uses an unrelated company to act as custodian and
     clearing firm for its investment assets. Net revenues earned by the traders
     at the brokerage firm, excluding the Company Chairman, related to
     investment transactions by the Company in 1998 and 1997 totaled $35,918 and
     $1,579 on purchase and sale transactions of $78,810,916 and $6,137,000,
     respectively.

17.  FINANCIAL INSTRUMENTS

     The Banks are party to financial instruments with off-balance sheet risk in
     the normal course of business to meet the financing needs of their
     customers. These financial instruments include commitments to extend credit
     and standby letters of credit. Those instruments involve, to varying
     degrees, elements of credit and interest rate risk in excess of the amount
     recognized in the consolidated financial statements. The contract or
     notional amounts of those instruments reflect the extent of the Banks'
     involvement in particular classes of financial instruments.

     The Banks' exposure to credit loss in the event of nonperformance by the
     other party to the financial instrument for commitments to extend credit
     and standby letters of credit is represented by the contractual notional
     amount of those instruments. The Banks use the same credit policies in
     making commitments and conditional obligations as they do for on-balance
     sheet instruments.

     Commitments to extend credit are agreements to lend to a customer as long
     as there is no violation of any condition established in the contract.
     Commitments generally have fixed expiration dates or other termination
     clauses and may require payment of a fee. Since many of the commitments are
     expected to expire without being drawn upon, the total commitment amounts
     do not necessarily represent future cash requirements. The Banks evaluate
     each customer's creditworthiness on a case-by-case basis. The amount of
     collateral obtained, if it is deemed necessary by the Banks upon extension
     of credit, is based on management's credit evaluation of the counterparty.
     Collateral held varies but may include accounts receivable; inventory;
     property, plant, and equipment; and income-producing commercial properties.

     Standby letters of credit are conditional commitments issued by the Banks
     to guarantee the performance of a customer to a third party. Those
     guarantees are primarily issued to support public and private borrowing
     arrangements. The credit risk involved in issuing letters of credit is
     essentially the same as that involved in extending loan facilities to
     customers.

     A summary of the notional amounts of the Bank's financial instruments with
     off-balance sheet risk at December 31, 1998 is as follows:

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     SFAS No. 107, "Disclosures About Fair Value of Financial Instruments,"
     requires disclosure of fair value information about financial instruments,
     whether or not recognized in the consolidated balance sheet, for which it
     is practicable to estimate that value. In cases where quoted market prices
     are not available, fair values are based on estimates using present value
     or other valuation techniques. Those techniques are significantly affected
     by the assumptions used, including the discount rate and estimates of
     future cash flows. In that regard, the derived fair value estimates cannot
     be substantiated by comparison to independent markets and, in many cases,
     could not be realized in immediate settlement of the instrument. SFAS No.
     107 excludes certain financial instruments from its disclosure
     requirements. Accordingly, the aggregate fair value amounts presented do
     not represent the underlying value of the Company.

     The following methods and assumptions were used by the Company in
     estimating the fair value of its financial instruments:

         CARRYING AMOUNTS APPROXIMATE FAIR VALUES for cash and due from banks;
     interest bearing deposits in banks; federal funds sold; trading securities,
     securities available for sale; variable rate loans; accrued interest
     receivable and payable; demand deposits; NOW, money market, and savings
     accounts; and variable rate time deposits.

         QUOTED MARKET PRICES, where available, or if not available, based on
     quoted market prices of comparable instruments for securities to be held to
     maturity.

         DISCOUNTED CASH FLOWS using interest rates currently being offered on
     instruments with similar terms and with similar credit quality, including
     fixed rate loans; fixed rate time deposits; and other debt.

         QUOTED FEES CURRENTLY BEING CHARGED for off-balance-sheet instruments,
     including letters of credit and loan commitments.

     The estimated fair values of the Company's financial instruments were as
     Follows:

                  NATIONAL BANCSHARES OF TEXAS AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The fair value of off-balance sheet assets and liabilities is not
     considered significant.

     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 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. Other significant assets and
     liabilities that are not considered financial assets or liabilities include
     the deferred tax asset, bank premises and equipment, other real estate
     owned, and other assets. 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 the
     estimates.

18.  CONCENTRATIONS OF CREDIT

     Substantially all of the Banks' loans, commitments, and standby letters of
     credit have been granted to customers in the Banks' market areas which
     include South and Central Texas. Substantially all of these customers are
     depositors of the Banks. Investments in state and municipal securities also
     involve governmental entities within the Banks' market areas. The
     concentrations of credit by type of loan are set forth in Note 5. The
     distribution of commitments to extend credit approximates the distribution
     of loans outstanding. Standby letters of credit are granted primarily to
     commercial borrowers.

19.  REGULATORY MATTERS

     The amount of dividends that may be declared by the Banks without prior
     approval of the various regulatory agencies is limited by statutory and
     regulatory rules.

     The Company and its subsidiary Banks are required to maintain minimum
     ratios of Tier 1 capital to total average assets and minimum ratios of Tier
     1 and total capital to risk weighted assets, as defined by the banking
     regulators.

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

     Quantitative measures established by regulation to ensure capital adequacy
     require the Company and its subsidiary banks to maintain minimum amounts
     and ratios (set forth in the table below) of total and Tier 1 capital (as
     defined in the regulations) to risk-weighted assets (as defined), and of
     Tier 1 capital (as defined) to average assets (as defined). Management
     believes, as of December 31, 1998, that the Company and its subsidiary
     banks meet all capital adequacy requirements to which it is subject.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     As of December 31, 1998, the most recent notification from the Banking
     regulators categorized the Company and its subsidiary banks as "well
     capitalized" under the regulatory framework for prompt corrective action.
     To be categorized as "well capitalized" the Company and its subsidiary
     banks must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1
     leverage ratios as set forth in the table. There are no conditions or
     events since that notification that management believes have changed the
     institutions' categories.

     The Company and its subsidiary banks actual capital amounts and ratios are
     also presented in the table (Dollars in thousands).
