3.       NEW ACCOUNTING PRONOUNCEMENTS:

In June 2001, the Financial Accounting Standard Board ("FASB") issued SFAS No.
141, Business Combinations. SFAS No. 141 addresses financial accounting and
reporting for business combinations and supersedes Accounting Principles Board
("APB") Opinion No. 16, Business Combinations, and SFAS No. 38, Accounting for
Preacquisition Contingencies of Purchased Enterprises. This statement eliminates
the pooling of interests method for accounting for business combinations and
requires intangible assets that meet certain criteria to be reported separately
from goodwill. The provisions of this statement apply to all business
combinations initiated after June 30, 2001.

In June 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible
Assets. This statement addresses financial accounting and reporting for acquired
goodwill and other intangible assets and supersedes APB Opinion No. 17,
Intangible Assets. This statement requires that goodwill and intangible assets
with indefinite useful lives no longer be amortized, but instead be tested for
impairment at least annually. This statement also requires that intangible
assets with definite useful lives be amortized over their respective estimated
useful lives to their estimated residual values, and also be reviewed for
impairment. Impairment losses resulting from the initial application of this
statement are to be reported as a change in accounting principle. This statement
is effective for fiscal years beginning after December 15, 2001, and must be
applied to all goodwill and other intangible assets recognized in the financial
statements. The Company adopted this statement effective January 1, 2002 and
ceased amortization of goodwill.

Goodwill recognized in business combinations is not amortized, but is tested for
impairment under the provisions of SFAS 142 at a level of reporting referred to
as a reporting unit. To the extent a reporting unit's carrying amount exceeds it
fair value, an indication exists that the reporting unit's goodwill may be
impaired and the Company must perform a second step of the impairment test. In
the second step, if the carrying amount of reporting unit goodwill exceeds the
implied fair value of that goodwill, an impairment loss is recognized in an
amount equal to that excess. Goodwill of a reporting unit is tested for
impairment on an annual basis and between annual tests in certain circumstances.
The first step of the initial goodwill impairment test was completed by June 30,
2002 as required by SFAS 142. After performing this initial step, no goodwill
impairment was indicated.

The Company had no changes in the carrying amount of goodwill from December 31,
2001 to June 30, 2002. Also, the company has no intangible assets other than
goodwill.

The following table is a reconciliation of net income, basic earnings per share,
and diluted earnings per share with and without goodwill amortization:

In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or
Disposal of Long-Lived Assets. This statement supersedes SFAS No. 121,
Accounting for the Impairment of Long-Lived Assets and for

Long-Lived Assets to be Disposed of, and the accounting and reporting provisions
of APB Opinion No. 30, Reporting the Results of Operations - Reporting the
Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and
Infrequently Occurring Events and Transactions, for the disposal of a segment of
a business. This statement also amends Accounting Research Bulletin No. 51,
Consolidated Financial Statements. SFAS No. 144 is effective for fiscal years
beginning after December 15, 2001, and interim periods within those fiscal
years, with early application encouraged. The effects of this statement did not
have a material impact on the Company's financial position or results of
operations upon adoption on January 1, 2002.

In May 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No. 4,
44, and 64, Amendment of FASB Statement No. 13 and Technical Corrections". SFAS
No. 145 rescinds SFAS No. 4, "Reporting Gains and Losses from Extinguishment of
Debt," and an amendment of that statement, SFAS No. 64, "Extinguishments of Debt
Made to Satisfy Sinking-Fund Requirements. This statement also amends SFAS No.
113, "Accounting for Leases," to eliminate an inconsistency between the required
accounting for sale-leaseback transactions and the required accounting for
certain lease modifications that have economic effects that are similar to
sale-leaseback transactions. This statement also amends other existing
authoritative pronouncements to make various technical corrections, clarify
meanings, or describe their applicability under changed conditions. The
provisions of this statement are effective for fiscal years beginning after May
15, 2002. The effects of this statement are not expected to have a material
impact on the Company's consolidated financial position or results of
operations; however, the statement will cause the Company to reclassify its loss
on early extinguishment of debt during fiscal 2001 as a component of ordinary
income.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities". SFAS No. 146 requires the recognition of
costs associated with exit or disposal activities when they are incurred rather
than at the date of a commitment to an exit or disposal plan. The provisions of
this statement are to be applied prospectively to exit or disposal activities
initiated after December 31, 2002. The effects of this statement are not
expected to have a material impact on the Company's financial position or
results of operations upon adoption on January 1, 2003.

COMPARISON OF FINANCIAL CONDITION AS OF JUNE 30, 2002 AND DECEMBER 31, 2001.
Total assets were $224.4 million, at June 30, 2002, as compared to $218.0
million at December 31, 2001. Total loans receivable, net decreased
approximately $8.2 million primarily due to refinancing activities and principal
repayments. Available-for-sale securities increased approximately $18.6 million
due to purchases exceeding calls and maturities. During the six-month period
ended June 30, 2002 the Bank had $6.0 million in agency securities called and
$3.0 million to mature. Also, during the six-month period ending June 30, 2002,
the Bank sold $3.0 million in agency securities. Gross gains of $20,000 were
realized on these sales and no losses were realized on these sales. With the
proceeds from these calls, maturities and sales of
securities-available-for-sale, combined with the proceeds from loan principal
repayments and FHLB advances, the Bank purchased $23.0 million in agency
securities and $8.2 million in mortgage-backed securities during the six-months
ended June 30, 2002.

At June 30, 2002 the Company's investment portfolio of $80.5 million consisted
primarily of U. S. agency securities and mortgage-backed securities. The entire
investment portfolio is classified as "available-for-sale," which is
marked-to-market with the unrealized gains/losses reflected directly in
stockholders' equity, net of taxes.

Total real estate owned decreased $812,000 to $1.5 million at June 30, 2002 as
compared to $2.3 million at December 31, 2001. This decrease was due to sales of
real estate owned of $1.4 million exceeding foreclosures of $652,000.

Total deposits increased $400,000 to $193.9 million at June 30, 2002 as compared
to $193.5 million at December 31, 2001. This relatively slight increase was
primarily due to rate competition.

During the six-month period ended June 30, 2002 the Bank increased it borrowed
funds by $4.2 million. The proceeds from borrowed funds were used to purchase
agency securities due to favorable spread.

RESULTS OF OPERATIONS-COMPARISON OF THE THREE AND SIX MONTHS ENDED JUNE 30, 2002
AND 2001. For the three-months ended June 30, 2002, net income was $516,000,
compared with net income of $106,000 for the three-months


                                       11
<PAGE>

ended June 30, 2001. Net interest income after the provision for loan losses for
the three-months ended June 30, 2002, was $1,622,000, compared with $966,000 in
the same period last year. For the six-months ended June 30, 2002, net income
was $957,000, compared with net income of $436,000 for the six-months ended June
30, 2001. This increase in net income for the six-months ended June 30, 2002 was
achieved despite a decrease in interest income of $1,667,000 primarily due to
lower prevailing interest rates on the Company's various funding sources. Net
interest income after the provision for loan losses for the six-months ended
June 30, 2002, was $3,170,000, compared with $2,507,000 in the same period last
year. The Company's net interest margin increased to 3.45% for the three-months
ended June 30, 2002, from 3.20% for the three-months ended June 30, 2001. The
Company's net interest margin increased to 3.42% for the six-months ended June
30, 2002, from 3.15% for the six-months ended June 30, 2001. The Company's net
interest margin increased as market interest rates stabilized at lower levels.
The provision for loan losses decreased from $670,000 to $120,000 and from
$790,000 to $260,300 for the three and six-month periods ended June 30, 2002 as
compared with June 30, 2001, respectively. This was the result of a decline in
non-performing loans.

If rates were to rise rapidly, net income may be adversely affected. Under a
scenario simulating a hypothetical 100 basis point rate increase applied to all
fixed rate interest-earning assets and interest-bearing liabilities, the Company
would expect a net loss in the fair value of the underlying instruments of
approximately $1,054,000. This hypothetical loss is not a precise indicator of
future events. Instead, it is a reasonable estimate of the results anticipated
if the assumptions used in the modeling techniques were to occur.

Economic conditions in most of the Company's principal market areas are
currently weak. Further weakness in these conditions could cause an increase in
the Company's non-performing assets and a deterioration in the company's asset
quality.

The Bank's yield on interest-earning assets decreased from approximately 7.84%
in the three-month period ended June 30, 2001 to approximately 6.53% in the
current year period. This decrease was due to a decrease in interest rates as
well as a decrease in the average balance of interest-earning assets of
approximately $3.0 million driven by a decrease in loans. The Bank's yield on
interest-earning assets decreased from approximately 7.97% in the six-month
period ended June 30, 2001 to approximately 6.62% in the current year period.
This decrease was due to a decrease in interest rates as well as a decrease in
the average balance of interest-earning assets of approximately $8.0 million
driven mainly by a decrease in loans. The Bank's cost of funds decreased from
approximately 4.75% at June 30, 2001 to approximately 3.02% in the current year
period. This decrease was due to a decrease in interest rates as well as a
decrease in the average balance of interest bearing liabilities of approximately
$3.2 million.

Non-interest income, which includes fees and service charges, real estate
operations, net gain (loss) on sale of loans, Bank owned life insurance and
other income increased $99,000 in the three-month period ended June 30, 2002, as
compared to the three-month period ended June 30, 2001. The increase was due
primarily to an increase in the cash surrender value of Bank owned life
insurance of $65,000, an increase in fees and service charges of $43,000, and an
increase in the gain on sale of securities available-for-sale of $20,000. These
combined increases were offset by a decrease in the gain on sale of mortgage
loans of $25,000 as well as slight decrease in all other non-interest income.
Non-interest income increased $132,000 in the six-month period ended June 30,
2002, as compared to the six-month period ended June 30, 2001. The increase was
due primarily to an increase in the cash surrender value of Bank owned life
insurance of $136,000, an increase in fees and service charges of $105,000, and
an increase in the gain on sale of real estate owned of $24,000. These combined
increases were offset by a decrease in the gain on sale of mortgage loans of
$58,000, a decrease in real estate operations, net of $30,000, a decrease in the
gain on sale of securities available-for sale of $40,000 as well as slight
decrease in all other non-interest income.

Provisions for loan losses are made to maintain the allowance for loan losses at
an adequate level. The allowance for loan losses reflects management's
estimates, which take into account historical experience, the amount of
non-performing assets, and general economic conditions. The Bank determined an
additional $670,000 was required for the three-month period ended June 30, 2001
and an additional $790,000 was required for the six-month period ended June 30,
2001. The Bank determined an additional $120,000 was required for the
three-month period ended June 30, 2002 and an additional $260,000 was required
for the six-month period ended June 30, 2002. The decrease in the provision for
loan losses for the three and six-month period ended


                                       12
<PAGE>

June 30, 2002 was the result of improvements in non-performing assets. It is
management's opinion that the allowance for loan losses at June 30, 2002 was
adequate to absorb losses related to the portfolio of loans. Management will
continue to analyze the Bank's exposure to losses and may adjust the allowance
for loan losses in the future if it deems necessary.

Non-interest expense increased $64,000 in the three-month period ended June 30,
2002, respectively, as compared to the corresponding prior year period. This was
primarily a result of an increase in compensation and benefits of $13,000, an
increase in occupancy expense of $19,000, an increase in marketing and
professional expense of $8,000, and an increase all other non-interest expense
of $24,000. Non-interest expense increased $68,000 in the six-month periods
ended June 30, 2002, respectively, as compared to the corresponding prior year
period. This increase was primarily a result of an increase in compensation and
benefits of $15,000, an increase in occupancy expense of $15,000, an increase in
marketing and professional expense of $23,000, and an increase in all other
non-interest expense of $15,000. These increases in non-interest expenses for
both the three and six months ended June 30, 2002 were not the result of any
single significant factor.

EXTRAORDINARY EXPENSE. In the first quarter of 2001, the Company incurred an
extraordinary expense, net of tax benefit, of $108,000 due to penalties on the
prepayment of Federal Home Loan Bank advances totaling $16.5 million. The Bank
determined to use a portion of its excess liquidity to prepay these advances,
which would have matured in July, November and December of 2001.

CAPITAL RESOURCES: Historically, funds provided by operations, mortgage loan
principal repayments, savings deposits and short-term borrowings have been the
Bank's principal sources of funds. In addition, the Bank has the ability to
obtain funds through the sale of mortgage loans, through borrowings from the
Federal Home Bank of Atlanta and other borrowing sources. At June 30, 2002, the
Bank's total loan commitments, including construction loans in process and
unused lines of credit, were approximately $22.0 million. Management believes
that the Bank's liquidity and other sources of funds are sufficient to fund all
commitments outstanding and other cash needs. The Company and the Bank are
required to maintain certain levels of regulatory capital. At June 30, 2002, the
Company and the Bank exceeded all regulatory capital requirements.
