such adjustments are of a normal recurring nature. These financial statements
and the notes thereto should be read in conjunction with the Company's
Prospectus which is a part of the Registration Statement on Form S-1
(Registration No. 333-48959) filed with the SEC on May 11, 1998.  Operating

OVERVIEW

     Net earnings available to common shareholders for the six months ended June
30, 1998 were $1.2 million or $0.43 per share compared to $1.0 million or $0.40
per share for the six months ended June 30, 1997, an increase of 11.9%.  While
aided by an increase in net interest income, the improvement in net earnings was
primarily the result of a gain on the sale of approximately $2.0 million in
principal amount of mortgage loans that were originally purchased in 1991 at a
discount from the Resolution Trust Corporation("RTC").  In March of 1998, the
Company sold the mortgage loans at par, which resulted in a gain of $444,000,
net of $230,000 in taxes expensed as a result of the sale.  The Company did not
have a gain from the sale of loans in the first six months of 1997.  The gain on
the sale of the loans in 1998 was partially offset by an increase in the
provision for loan losses from $40,000 in the first six months of 1997 to
$430,000 in the first six months of 1998 primarily as the result of a $23.8
million or 16.3% increase in loans during the same time period.  Accordingly,
after giving effect to these transactions, core earnings available to common
shareholders for the period were $1.1 million or $0.41 per share for the first
six months of 1998 compared to $1.0 million or $0.40 per share for the first six
months of 1997, a 6.6% increase.

     The six month period ended June 30, 1998 showed good growth.  Total loans
increased to $169.9 million at June 30, 1998 from $157.4 million at December 31,
1997, an increase of $12.5 million or 7.9%.  Total assets were $254.6 million at
June 30, 1998 compared with $244.2 million at December 31, 1997.  The increase
in total assets resulted mainly from an increase in total deposits to $228.3
million at June 30, 1998 from $223.0 million at December 31, 1997, an increase
of $5.3 million or 2.4%, and an increase in shareholders equity of $5.3 million.
Common shareholders' equity was $22.7 million at June 30, 1998 compared with
$17.4 million at December 31, 1997, an increase of $5.3 million or 30.5%.  This
increase was due to the initial public offering proceeds of $4.5 million (net of
expenses), net earnings for the period of $1.2 million less dividends paid of
$356,000, and the redemption of the preferred stock of $827,000.

RESULTS OF OPERATIONS

Interest Income

     Interest income for the six months ended June 30, 1998 was $9.0 million, an
increase of $1.1 million or 13.5% from the six months ended June 30, 1997.  The
increase in interest income was due primarily to higher interest income on loans
and securities.  Average loans were $162.1 million for the six months ended June
30, 1998 compared with $142.1 million for the six months ended June 30, 1997, an
increase of $20.0 million or 14.1%.  Internal growth accounted for all of the
$20.0 million increase in average loans.  Average securities were $52.7 million
for the six months ended June 30, 1998 compared with $44.8 million for the six
months ended June 30, 1997, an increase of $7.9 million or 17.6%.

Interest Expense

     Interest expense on deposits and other interest-bearing liabilities was
$4.5 million for the six months ended June 30, 1998 compared with $3.9 million
for the six months ended June 30, 1997, an increase of $601,000 or 15.5%. The
increase in interest expense was due primarily to an increase in average
interest-bearing liabilities, to $182.2 million for the six months ended June
30, 1998 from $163.1 million for the six months ended June 30, 1997, an increase
of $19.1 million or 11.7%. In addition, the interest rate on average interest-
bearing liabilities increased to 4.97% from 4.81% for the same periods.


Net Interest Income

     Net interest income was $4.6 million for the six months ended June 30, 1998
compared with $4.1 million for the six months ended June 30, 1997, an increase
of $476,000 or 11.6%. The increase in net interest income resulted primarily
from growth in average earning assets to $226.2 million for the six months ended
June 30, 1998 from $197.0 million for the six months ended June 30, 1997, an
increase of $29.2 million or 14.8%.

     The Company's net interest income is affected by changes in the amount and
mix of interest-earning assets and interest-bearing liabilities, referred to as
a "volume change." It is also affected by changes in yields earned on interest-
earning assets and rates paid on interest-bearing deposits and other borrowed
funds, referred to as a "rate change." The following tables set forth, for each
category of interest-earning assets and interest-bearing liabilities, the
average amounts outstanding, the interest earned or paid on such amounts, and
the average rate earned or paid for the six months ended June 30, 1998 and 1997.
The tables also set forth the average rate earned on total interest-earning
assets, the average rate paid on total interest-bearing liabilities, and the net
interest margin on average total interest-earning assets for the same periods.

Provision and Allowance for Loan Losses

     In originating loans, the Company recognizes that credit losses will be
experienced and the risk of loss will vary with, among other things, general
economic conditions, the type of loan being made, the creditworthiness of the
borrower over the term of the loan and, in the case of a collateralized loan,
the quality of the collateral for such loan. The Company maintains an allowance
for loan losses based upon, among other things, historical experience, the
volume and type of lending conducted by the Company, the amount of nonperforming
assets, regulatory policies, generally accepted accounting principles, general
economic conditions, and other factors related to the collectibility of loans in
the Company's portfolio. In addition to unallocated allowances, specific
allowances are provided for individual loans when ultimate collection is
considered questionable by management after reviewing the current status of
loans which are contractually past due and considering the net realizable value
of the collateral for the loan.

     Management actively monitors the Company's asset quality and provides
specific loss allowances when necessary. Loans are charged-off against the
allowance for loan losses when appropriate. Although management believes it uses
the best information available to make determinations with respect to the
allowance for loan losses, future adjustments may be necessary if economic
conditions differ from the assumptions used in making the initial
determinations. As of June 30, 1998, the allowance for loan losses amounted to
$1.4 million or 0.85% of total loans. The allowance for loan losses as a
percentage of nonperforming loans was 162.9% at June 30, 1998.

     Provisions for loan losses are charged to income to bring the total
allowance for loan losses to a level deemed appropriate by management of the
Company based on such factors as historical experience, the volume and type of
lending conducted by the Company, the amount of nonperforming assets, regulatory
policies, generally accepted accounting principles, general economic conditions,
and other factors related to the collectibility of loans in the Company's
portfolio.

     The provision for loan losses for the six months ended June 30, 1998 was
$430,000 compared with $40,000 for the six months ended June 30, 1997. The
increase in the provision came primarily as a result of the growth in the loan
portfolio from $146.1 million at June 30, 1997 to $169.9 million at June 30,
1998.  The provision was incurred to increase the allowance for loan losses to a
more appropriate level and to allow for continued loan growth. For the six
months ended June 30, 1998, net charge-offs were $124,000.

Noninterest Income

     The Company's primary sources of recurring noninterest income are service
charges on deposit accounts and fee income. Excluding a $674,000 nonrecurring
gain from the sale of loans, noninterest income for the six months ended June
30, 1998 increased to $954,000 from $793,000 for the six months ended June 30,
1997, an increase of $161,000 or 20.3%.  The gain on sale of loans was recorded
when the Company sold approximately $2.0 million of loans originally purchased
at a discount in June of 1991 from the RTC.  The following table presents, for
the periods indicated, the major categories of noninterest income:

     After excluding the nonrecurring gain on the sale of loans, the increase in
noninterest income from June 30, 1997 to June 30, 1998, resulted primarily from
an increase in service charges on deposit accounts and fee income due to an
increase in the number of deposit accounts.  Additionally, the Company's
increased emphasis on fee based services resulted in greater income from check
cashing, ATM fees, appraisal fees and wire transfer fees.

Noninterest Expenses

Noninterest expenses totaled $4.2 million for the six months ended June 30, 1998
compared with $3.6 million for the six months ended June 30, 1997, an increase
of $584,000 or 16.1%. The following table presents, for the periods indicated,

     Employee compensation and benefits expense for the six months ended June
30, 1998 was $2.1 million, an increase of $345,000 or 19.2% over the $1.8
million for the same period in 1997. The increase was due primarily to normal
salary increases and the staffing of a new location in Texarkana, which opened
in August of 1997, and additional staff at the Mt. Pleasant location to handle
customer growth. The number of full-time equivalent employees was 132 at June
30, 1998 compared with 113 at June 30, 1997, an increase of 16.8%.

     Non-staff expenses were $2.1 million for the six months ended June 30, 1998
compared with $1.8 million for the same period in 1997, an increase of $239,000
or 13.0%. Net bank premises expense decreased $36,000 or 5.8% to $583,000.

     Legal and professional fees increased $43,000 or 29.7% due primarily to
independent loan review expenses and bankruptcy and litigation proceedings.  The
increase in advertising of $32,000 or 32.0% was due to additional advertising
campaigns initiated in early 1998 as compared to the same time period of 1997.
Other non-staff expenses include director fees, insurance, franchise tax,
telephone expense and other miscellaneous expenses, the combination of which
increased $194,000 or 25.3% to $959,000 as of June 30, 1998.

Income Taxes

     Income tax expense increased approximately $215,000 to $370,000 for the
six months ended June 30, 1998 from $155,000 for the same period in 1997. The
increase was primarily attributable to the gain on sale of loans in the amount
of $674,000.  The Company did not have a gain from the sale of loans in the
first six months of 1997.

FINANCIAL CONDITION

Loan Portfolio

     Total loans were $169.9 million at June 30, 1998, an increase of $12.5
million or 7.9% from $157.4 million at December 31, 1997. Loan growth occurred
primarily in commercial loans, 1 to 4 family residential loans and farmland
loans. Loans comprised 73.5% of total earning assets at June 30, 1998 compared
with 70.5% at December 31, 1997.

NONPERFORMING ASSETS

     Nonperforming assets were $1.0 million at June 30, 1998 compared with
$1.9 million at December 31, 1997, reflecting continued strong asset quality and
improving trends in nonperforming assets. The ratio of nonperforming assets to
total loans and other real estate was 0.6% and 1.2% at June 30, 1998 and
December 31, 1997, respectively.

SECURITIES

     Securities totaled $49.4 million at June 30, 1998, a decline of $8.7
million from $58.1 million at December 31, 1997. The decline occurred as
maturing securities were used to fund loans. At June 30, 1998, securities
represented 19.4% of total assets compared with 23.8% of total assets at
December 31, 1997. The yield on average securities for the six months ended June
30, 1998 was 6.56% compared with 6.55% for the same period in 1997. At June 30,
1998, securities included $8.2 million in U.S. Treasury securities, $20.6
million in U.S. Government securities, $18.4 million in mortgage-backed
securities, $1.1 million in equity securities and $1.1 million in municipal
securities. The average life of the securities portfolio at June 30, 1998 was
approximately two years and five months.

PREMISES AND EQUIPMENT

     Premises and equipment totaled $6.7 million at June 30, 1998 and $6.4
million at December 31, 1997 an increase of $303,000 or 4.8%.  Although the net
change shows only a slight increase in fixed assets, some assets were
capitalized during the period and normal depreciation was recorded.

OTHER ASSETS

     On July 1, 1998, the Company entered into an incentive retirement plan to
provide future retirement benefits for eleven of its key senior officers.  The
plan is a non-qualified plan that supplements its current 401(K) Plan.  The plan
will be provided by the Board of Directors on a yearly grant based on a
percentage of salary as each selected officer's contribution.  The benefit of
the plan is based on the Company's annual ROE.  The total contribution of the
plan was funded with a single insurance premium of $3.1 million.  The Company
did not have an incentive retirement plan in 1997.
 
DEPOSITS

     At June 30, 1998, demand, money market and savings deposits accounted for
approximately 45.4% of total deposits, while certificates

                                       18
<PAGE>
 
of deposit made up 54.6% of total deposits. Noninterest-bearing demand deposits
totaled $47.2 million or 20.7% of total deposits at June 30, 1998 compared with
$46.3 million or 20.8% of total deposits at December 31, 1997. The average cost
of deposits, including noninterest-bearing demand deposits, was 4.00% for the
six months ended June 30, 1998 compared with 3.88% for the same period in 1997.
The increase in the average cost of deposits was primarily due to the increased
share of interest-bearing deposits.

LIQUIDITY

     The Company's Asset/Liability Management Policy is intended to maintain
adequate liquidity for the Company. Liquidity involves the Company's ability to
raise funds to support asset growth or reduce assets to meet deposit withdrawals
and other payment obligations, to maintain reserve requirements and otherwise to
operate the Company on an ongoing basis.  The Company's liquidity needs are
primarily met by growth in core deposits.  Although access to purchased funds
from correspondent banks is available and has been utilized on occasion to take
advantage of investment opportunities, the Company does not rely on these
external funding sources.  The cash and federal funds sold position,
supplemented by amortizing investments along with payments and maturities within
the loan portfolio, have historically created an adequate liquidity position.

     The Company's cash flows are composed of three classifications: cash
flows from operating activities, cash flows from investing activities, and cash
flows from financing activities. Net cash provided  by operating activities was
$673,000 and $946,000 for the six months ended June 30, 1998 and 1997,
respectively.

     Net cash (used) by investing activities was $(10.1) million and $(14.8)
million for the six months ended June 30, 1998 and 1997, respectively. During
the six months ended June 30, 1998, the Company funded more loans than it
received in maturing investments. The Company also experienced an increase in
federal funds in the six months ended June 30, 1998 over the six months ended
June 30, 1997.

     Net cash provided by financing activities was $8.6 million and $7.5
million for the six months ended June 30, 1998 and 1997, respectively. The
difference was due primarily to the sale of common stock of $4.5 million offset
by the redemption of preferred stock of $827,000 during the six months ended
June 30, 1998.

CAPITAL RESOURCES

     Total shareholders' equity as of June 30, 1998 was $22.7 million, an
increase of $4.4 million or 24.5% compared with shareholders' equity of $18.3
million at December 31, 1997. The increase was due to the initial public
offering proceeds of $4.5 million (net of expenses), net earnings for the period
of $1.2 million less dividends paid on common and preferred stock of $356,000
and the redemption of the preferred stock of $827,000.

     Both the Board of Governors of the Federal Reserve System, with respect to
the Company, and the Federal Deposit Insurance Corporation, with respect to the
Bank, have established certain minimum risk-based capital standards that apply
to bank holding companies and federally insured banks, respectively. The
Company's risk-based capital ratios remain above the levels designated as "well
capitalized" on June 30, 1998, with Tier 1 capital, total risk-based capital and
leverage capital ratios of 12.56%, 13.36% and 9.07%, respectively. The Bank's
risk-based capital ratios remain above the levels designated as "well
capitalized" on June 30, 1998, with Tier-1 capital, total risk-based capital and
leverage capital ratios of 12.65%, 13.49% and 8.74%, respectively.

YEAR 2000

     The Company established a Year 2000 Task Force in September 1997 to ensure
there will be no material adverse effect on customers or disruption to business
operations as a result of a failure of the Company or third parties to properly
process any data on or after January 1, 2000. The project plan consists of five
phases - Awareness, Assessment, Renovation, Validation and Implementation. The
Awareness and Assessment phases are complete and the Renovation and Validation
phases are currently in process and on schedule. The inventory of systems has
been performed and the risk assessment and prioritizing of those systems is
complete. The Company does not utilize any in-house developed software. All
software utilized has been provided by established software companies who retain
the responsibility for Year 2000 compliance. These respective vendors have been
contacted and requested to provide the current compliance status of their
respective software and hardware systems. Their responses are being actively
monitored and testing schedules are being developed and deployed based on the
responses. It is anticipated that the validation phase will be complete by late
1998 or the first quarter 1999. Incremental costs for causing computer
applications to be Year 2000 compliant are presently estimated to be immaterial.
The Company is currently conducting thorough internal testing of all third party
hardware and software systems in an attempt to ensure Year 2000 compliance.  The
Company is also developing detailed contingency plans in the event of any system
failure associated with Year 2000.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company's primary market risk exposure is to changes in market
interest rates.  The Company's exposure to such risk is reviewed on a regular
basis by the Asset Liability Committee.  Interest rate risk is the potential of
economic losses due to future interest rate changes.  These economic losses can
be reflected as a loss of future net interest income and/or a loss of current
fair market values.  The objective is to measure the effect on net interest
income and to adjust the balance sheet to minimize the inherent risk while at
the same time maximizing income.  Management realizes certain risks are
inherent, and that the goal is to identify and accept the risks.

     The Company applies a market value ("MV") methodology to gauge its interest
rate risk exposure as derived from its simulation model.  Generally, MV is the
discounted present value of the difference between incoming cash flows on
interest-earning assets and other investments and outgoing cash flows on
interest-bearing liabilities.  The application of the methodology attempts to
quantify interest rate risk by measuring the change in the MV that would result
from a theoretical 200 basis point change in market interest rates.  Both a 200
basis point increase and a 200 basis point decrease in market rates are
considered.

     At June 30, 1998, it was estimated that the Company's MV would decrease
16.7% in the event of a 200 basis point increase in market interest rates.  The
Company's MV at the same date would increase 11.4% in the event of a 200 basis
point decrease in market interest rates.
