                        DECATUR FIRST BANK GROUP, INC.

                         Notes to Financial Statements

(1)    Organization
       ------------

       Decatur First Bank Group, Inc. (the Company), a bank holding company,
       owns 100% of the outstanding common stock of Decatur First Bank (the
       Bank), which operates in the Decatur, Georgia area.

       Operations through June 30, 1997 relate primarily to expenditures by the
       organizers for incorporating and organizing the Company. On September 2,
       1997, the Bank opened for business to serve the Decatur/DeKalb County
       area as a commercial bank. The Bank is chartered and regulated by the
       State of Georgia Department of Banking and Finance and is insured by and
       subject to regulation by the Federal Deposit Insurance Corporation.

       The Company raised $9,415,000 through an offering of its $5 par value
       common stock at $10 per share, of which $8,000,000 was used to capitalize
       the Bank.

       The interim financial statements included herein are unaudited but
       reflect all adjustments which, in the opinion of management, are
       necessary for a fair presentation of the financial position and results
       of operations for the interim period presented. All such adjustments are
       of a normal recurring nature. The results of operations for the period
       ended September 30, 1997 are not necessarily indicative of the results of
       a full year's operations.

(2)    Basis of Presentation
       ---------------------

       The consolidated financial statements include the accounts of the Company
       and the Bank. All intercompany accounts and transactions have been
       eliminated in consolidation. The financial statements of the Company
       through June 30, 1997 were presented as a Development Stage Corporation.

       The accounting principles followed by the Company and its subsidiary, and
       the method of applying these principles, conform with generally accepted
       accounting principles (GAAP) and with general practices within the
       banking industry. In preparing financial statements in conformity with
       GAAP, management is required to make estimates and assumptions that
       affect the reported amounts in the financial statements. Actual results
       could differ significantly from those estimates. Material estimates
       common to the banking industry that are particularly susceptible to
       significant change in the near term include, but are not limited to, the
       determination of the allowance for loan losses, the valuation of real
       estate acquired in connection with foreclosures or in satisfaction of
       loans, and valuation allowances associated with the realization of
       deferred tax assets which are based on future taxable income.

(3)    Proforma Net Loss Per Common Share
       ----------------------------------

       Proforma net loss per common share is calculated by dividing net loss by
       the total number of common shares which were sold in the initial public
       offering, and would be considered outstanding for all periods presented,
       as prescribed in Staff Accounting Bulletin Topic 1:B.

Item 2.  Management's Discussion and Analysis of Financial Condition and 
         Results of Operations

On June 30, 1997, the Company concluded its offering by selling 941,544 shares
of common stock at $10.00 per share. This provided the Company with $9,375,756
in capital after deducting deferred offering expenses of $39,684. Operations
through June 30, 1997 related primarily to organizing the Company and
pre-opening expenditures to prepare for opening the Bank. On September 2, 1997,
the Bank opened for business to serve the Decatur area as a commercial bank.

As of September 30, 1997, the Bank had concluded one full month of operations,
and the Company has total assets of 11,066,450. During this period, total
deposits had grown to $2,024,674 and total loans had grown to $262,661. The Bank
has $5,142,318 in its investment portfolio, with an additional $3,870,000 in
overnight investments at September 30, 1997.

At quarter end the Bank's loan to deposit ratio was 13%. Management's long term
target for the loan to deposit ratio is 75%. The interest rates being paid on
interest bearing deposits and the service charge rates for deposit services are
comparable to local market rates. Management is making a concerted effort to
develop quality loan business in the local market and to manage the deposit
growth consistent with expected loan demand.

The deposit mix at September 30, 1997 was as follows: $369,184 (18% of total
deposits) in non-interest bearing demand deposits; $1,176,398 (58% of total
deposits) in interest checking accounts; $52,788 (3% of total deposits) in
savings accounts; and $426,303 (21% of total deposits) in time deposits. As the
Bank continues to grow, management expects the deposit mix to become more
heavily weighted towards the higher costing time deposits, thus increasing the
average cost of funds and reducing the Bank's net interest margin.

While the Bank continues to build its loan portfolio, excess funds are invested
in short to intermediate term government and agency securities. At September 30,
1997, investment securities held to maturity were $3,287,801 and securities
available for sale were $1,854,517. Overnight interest bearing deposits (federal
funds sold) with other banks were $3,870,000. The current investment portfolio
strategy is primarily to provide liquidity for funding loans and initial
operating expenditures and secondarily for earnings enhancement. Accordingly, no
investment securities have final maturities greater than five years and all are
pledgeable to raise funding through secured borrowing or repurchase agreements.

Premises and equipment (net of depreciation) were $822,254 and consisted
primarily of improvements to the current leased facility as well as furniture
and fixtures acquired.

The Company had an accumulated deficit of $375,096 as of September 30, 1997.
During the first nine months of 1997, the Company incurred a net loss of
$268,596 compared to a net loss of $43,398 through September 30, 1996. The first
three quarters of 1997 reflected one full month of banking operations with
full-time employees in the leased bank site, whereas through September 30, 1996
reflected the costs associated with early stage development of the Company when
it had substantially no earning assets until the fourth quarter and only two
employees until mid 1997.

Net interest income for the nine months ended September 30, 1997 was $149,118
($121,892 in the third quarter). In the comparable period for 1996, the
Company's working capital came from lines of credit guaranteed by the Company's
organizers. The 1996 interest expense was in connection with those lines. All
working capital lines of credit were paid off in July 1997. The Company had
interest expense on interest bearing deposits and the lines of credit of $25,075
for the first nine months of 1997 ($9,945 in the third quarter).

Total interest income in the first three quarters of 1997 was $174,193 ($131,837
in the third quarter). Interest income on loans including fees was $2,485 in the
first three quarters of 1997 (all in the third quarter). Loan interest income
and deposit interest expense in 1997 were not incurred until the Bank opened on
September 2, 1997.

Item 2.   Management's Discussion and Analysis of Financial Condition and 
          Results of Operations, continued

The provision for loan losses for the nine months ended September 30, 1997 was
$5,400 (all in the third quarter). Since the Bank's loan portfolio is only one
month old, the Bank has no historical data about loan losses on its portfolio on
which to base projections for future losses. Current loan quality analysis does
not indicate potential loan losses. Until more substantial evidence about
potential loan losses is developed, management believes the Bank should
establish an allowance for loan losses that will approximate 1.5% of total
loans. At September 30, 1997, the allowance for loan losses was $5,400, which
represented 2.06% of total loans. Management expects the allowance for loan
losses to settle at the 1.5% level in the next 9 to 15 months.

Non-interest income for the nine months ended September 30, 1997 was $1,497 (all
in the third quarter). This consists of service charges on deposit accounts and
miscellaneous service fees.

Non-interest expense for the first three quarters of 1997 was $413,811 ($220,518
in the third quarter) compared to $43,158 for the same period in 1996. Salaries
and benefits increased substantially when the Bank commenced operations in
September 1997 with 12 employees compared to only two employees in 1996.
Occupancy costs are up in 1997 with operations occurring in the rented office
space until the permanent bank building was remodeled. Other operating expenses
for the first nine months increased from $10,794 in 1996 to $164,982 in 1997 and
include many expenses that were not necessary in 1996, such as data processing
services, business development, professional fees, postage, supplies and
communications costs.

Management does not expect the Company to make a quarterly profit until at 
least the second half of 1998, while it establishes its position in the local
market and builds its banking services infrastructure. Management continues to
believe that the local market presents good opportunities for business
development to support a growing and profitable community bank. Despite the
anticipated losses in the first years of operations, the Company expects
earnings from loans and investments and other banking services as well as steady
deposit growth to provide sufficient liquidity for both the short and long term.
The Bank intends to manage its loan growth such that deposit flows will provide
funding for all loans as well as cash reserves for working capital and short to
intermediate term, liquid investments.

The Bank has established short-term Federal Funds Purchase lines of credit with
its correspondent bank which totals $2,000,000. This line is unsecured and is
designed to provide the Bank with short-term liquidity. This line may be revoked
at any time by the correspondent bank and is available to the Bank simply as an
accommodation for short-term (two weeks or less) liquidity needs.

In the early years, the investment practices of the Company will limit
investments to highly liquid overnight investments in correspondent banks and
short to intermediate term U.S. Treasury and government agency securities. For
the foreseeable future, the Bank will consider its investment portfolio
primarily as a source for liquidity and secondarily as a source for earnings.
