                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  JUNE 30, 2000
                                   (UNAUDITED)

(1) BASIS OF PRESENTATION

The consolidated financial statements include the accounts of WGNB Corp. (the
"Company") and its wholly-owned subsidiaries, West Georgia National Bank (the
"Bank") and West Georgia Credit Services, Inc. (the "Finance Company"). All
significant inter-company accounts have been eliminated in consolidation. In
some cases, certain prior period amounts have been reclassified to conform with
current year presentation.

The accompanying unaudited interim consolidated financial statements reflect all
adjustments which, in the opinion of management, are necessary to present fairly
the Company's financial position as of June 30, 2000, and the results of its
operations and its cash flows for the six-month period then ended. All such
adjustments are normal and recurring in nature. The financial statements
included herein should be read in conjunction with consolidated financial
statements and the related notes and the report of independent accountants
included in the Company's initial filing on form 10-SB which included the
results of operations for the years ended December 31, 1999 and 1998.

(2) NET EARNINGS PER SHARE

Basic earnings per share is based on the weighted average number of common
shares outstanding during the period while the effects of potential common
shares outstanding during the period are included in diluted earnings per share.
The average market price during the year is used to compute equivalent shares.
All net earnings per share amounts have been restated to conform to the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 128.

Reconciliation of the amounts used in the Computation of both "basic earnings
per share" and "diluted earnings per share" for the six month periods ended June
30, 2000 and June 30, 1999 are as follows:

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

FORWARD LOOKING STATEMENTS

This report may contain certain "forward-looking statements" including
statements concerning plans, objectives, future events or performance and
assumptions and other statements that are not statements of historical fact. The
Company cautions readers that the following important factors, among others,
could cause the Company's actual results to differ materially from the
forward-looking statements contained in this report: (i) the effect of changes
in laws and regulations, including federal and state banking laws and
regulations, with which the Company and its subsidiaries must comply, and the
associated costs of compliance with such laws and regulations either currently
or in the future as applicable; (ii) the effect of changes in accounting
policies and practices, as may be adopted by the regulatory agencies as well as
by the Financial Accounting Standards Board, or of changes in the Company's
organization, compensation and benefit plans; (iii) the effect on the Company's
competitive position within its market area of the increasing consolidation
within the banking and financial services industries, including the increased
competition from larger regional and out-of-state banking organizations as well
as non-bank providers of various financial services; (iv) the effect of changes
in interest rates; and (v) the effect of changes in the business cycle and
downturns in local, regional or national economies. The Company cautions that
the foregoing list of important factors is not exclusive. The Company does not
undertake to update any forward-looking statement, whether written or oral, that
the Company or its agents may make from time to time.

RESULTS OF OPERATIONS

OVERVIEW

Net earnings for the six months ended June 30, 2000 was $2.1 million, which
represented an increase of $450,000 or 27% compared to the six months ended June
30, 1999. Net earnings per common share increased 28% from $.53 per share to
$.68 per share when comparing the same two periods. Net earnings for the second
quarter ended June 30, 2000 was $1.1 million compared to $833,000 for the second
quarter of 1999. The second quarter of 2000 marks the first quarter that the
company earned more than $1 million in a single quarter. The improved operating
results are attributable to loan growth of $30.3 million when compared to
December 31, 1999. This loan growth caused net interest income to increase by
over $1.0 million or 18% when comparing the first six months of 2000 with the
same period in 1999.

NET INTEREST INCOME

For the first six months of 2000 compared to the same period in 1999, the
increase in interest income was $1.9 million or 20% and interest expense
increased $843,000 or 22%. Net interest income improved over $1 million or 18%
comparing the six month periods. The increase in interest income resulted from
an increase in average earning assets of approximately $40 million, while
average interest-bearing liabilities increased $28 million. The Company's net
interest margin increased approximately 13 basis points from 5.27% at June 30,
1999 to 5.40% at June 30, 2000.

OTHER INCOME AND EXPENSE

Other income for the first six months of 2000 increased $145,000 or 13% compared
to the first six months of 1999. Service charges on deposit accounts increased
$123,000 or 19% during 2000 compared to the first six months of 1999. This
increase was due primarily to increased income from non-sufficient funds
charges. Miscellaneous other income also increased by $22,000 or 5%.
Miscellaneous other income includes residential mortgage loan origination fees
as well as other fees, gains and losses.

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

Other expense increased $539,000 or 14% in the first two quarters of 2000
compared to the same period in 1999. Salaries and employee benefits increased
$392,000, an 18% increase over the first six months of 1999. The increase was
primarily due to additional staffing requirements in the operations and lending
departments in the Bank. The Bank increased its full time equivalent employee
count from 105 in June of 1999 to 115 in June of 2000. The increase is also
attributable to higher pay rates for employees due to annual raises and
increased profit sharing accruals due to higher earnings.

Occupancy and other operating expenses increased $147,000 or 9% from 1999 to
2000. Increased depreciation expense attributable to operations and retail
delivery equipment and software purchases accounted for $72,000 of the increase.
These fixed assets purchases were placed in service in late 1999 in preparation
for year 2000 compliance. In addition, the Bank purchased retail delivery tools
such as a new accounts platform, temporary facilities for the Bank's anticipated
"Mirror Lake" branch, and additional ATM sites in the Bank's market area to
increase the Bank's retail presence in its growing market.

INCOME TAXES

Income tax expense for the first six months was $1.1 million in 2000 compared to
$915,000 in 1999. The effective tax rates for each of the periods ended March
31, 2000 and 1999 were 35% and 36%, respectively.

PROVISION AND ALLOWANCE FOR POSSIBLE LOAN LOSSES

The adequacy of the allowance for loan losses is determined through management's
informed judgment concerning the amount of risk inherent in the Company's loan
portfolios. This judgment is based on such factors as the change in levels of
non-performing and past due loans, historical loan loss experience, borrowers'
financial condition, concentration of loans to specific borrowers and
industries, estimated values of underlying collateral, and current and
prospective economic conditions. The allowance for loan losses at June 30, 2000
was $2.52 million or 1.17% of total loans compared to $2.28 million or 1.24% of
total loans at December 31, 1999. Management believes that the allowance for
loan losses is adequate to absorb possible loss in the loan portfolio.

NON-PERFORMING ASSETS AND PAST DUE LOANS

Non-performing assets, comprised of real estate owned, non-accrual loans and
loans for which payments are more than 90 days past due, totaled $861,000 at
June 30, 2000 compared to $505,000 at June 30, 1999. Non-performing assets as a
percentage of total loans and real estate owned at June 30, 2000 and June 30,
1999 were 0.4% and .3%, respectively.

The Company has a loan review function that continually monitors selected
accruing loans for which general economic conditions or changes within a
particular industry could cause the borrowers financial difficulties. The loan
review function also identifies loans with high degrees of credit or other
risks. The focus of loan review as well as management is to maintain a low level
of non-performing assets and return current non-performing assets to earning
status. Management is unaware of any known trends, events or uncertainties that
will have or that are reasonably likely to have a material effect on liquidity,
capital resources or operations.

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

FINANCIAL CONDITION

OVERVIEW

Total assets were $276 million at June 30, 2000, an increase of $21.7 million or
8.6% from December 31, 1999, which equates to an annual growth rate of almost
17%.

ASSETS AND FUNDING

At June 30, 2000 earning assets totaled $258 million, an increase of more than
$25 million from December 31, 1999. The mix of interest earning assets has
changed slightly since the beginning of 2000. Loans increased to 83% and
investment securities decreased to 17% of earning assets at June 30, 2000
compared to loans of 79% and investments of 21% of earning assets at December
31, 1999.

At June 30, 2000, interest-bearing liabilities increased $18.8 million compared
to December 1999. Non-interest-bearing deposits increased $908,000 in the first
six months of 2000 and totaled $31.3 million at June 30, 2000. Federal Home Loan
Bank advances increased $5 million in the first half of 2000 and totaled $20
million at June 30, 2000. In addition, the Bank had purchased $6.2 million of
federal funds, which it intends to convert to additional Federal Home Loan Bank
advances in the third quarter of 2000. At June 30, 2000, deposits represented
88% of interest-bearing liabilities, federal funds purchased represented 3% and
Federal Home Loan Bank advances represented 9%.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities totaled $2.9 million for the six
months ended June 30, 2000. Net cash used by investing activities totaling $30.6
million consisted primarily of a $30.5 million increase in loans outstanding.
The loans were funded by an $8.5 increase in deposits, a $5.0 million increase
in Federal Home Loan Bank advances and a $6.2 million increase in federal funds
sold. The remainder of the funding was from cash generated in previous periods.
The decrease in cash and cash equivalents for the year to date June 30, 2000 was
$8.9 million.

Total stockholders' equity at June 30, 2000 was 8.40% of total assets compared
to 8.65% at December 31, 1999. The decrease in the capital percentage is
attributed to a $22 million increase in total assets since December 31, 1999.
Nearly all of the asset growth was in loans.

At June 30, 2000, WGNB Corp. was in compliance with various regulatory capital
requirements administered by federal and state banking agencies. The following
is a table representing WGNB Corp.'s consolidated Tier-1, tangible capital, and
risk-based capital.
