                         Notes to Financial Statements
                                  (Unaudited)


(1)  Organization and Basis of Presentation
     --------------------------------------

     Decatur First Bank Group, Inc. (Decatur First), a bank holding company,
     owns 100% of the outstanding common stock of Decatur First Bank (the Bank),
     which operates in the Decatur, Georgia area. The Bank opened for business
     on September 2, 1997.

     The consolidated financial statements include the accounts of Decatur First
     and the Bank. All intercompany accounts and transactions have been
     eliminated in consolidation.

     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 inteim period presented. All such adjustments are of a normal recurring
     nature. The results of operations for the period ended June 30, 1999 are
     not necessarily indicative of the results of a full year's operations.

     The accounting principles followed by Decatur First and the methods 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 determinations of the allowance for loan
     losses, the valuation of real estate acquired in connection with or in lieu
     of foreclosure on loans, and valuation allowances associated with deferred
     tax assets, the recognition of which are based on future taxable income.

                        DECATUR FIRST BANK GROUP, INC.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

                For the Six Months Ended June 30, 1999 and 1998

Financial Condition

   Total assets at June 30, 1999 were $40,228,800 representing a $1,782,700
(4.6%) increase from December 31, 1998. Deposits increased $2,244,428 (7.5%)
from December 31, 1998. Net loans increased $6,249,620 (64.7%). The allowance
for loan losses at June 30, 1999 totaled $330,419, representing 2.0% of total
loans compared to December 31, 1998 totals of $198,055 which represented 2.0% of
total loans. Cash and cash equivalents decreased $3,140,846 from December 31,
1998.

   There were no related party loans or other loans which were considered
nonperforming at June 30, 1999.

Results of Operations

   Net loss for the six months ended June 30, 1999 was $41,883, compared to a
net loss of $217,446 for the same period for 1998.  The decrease in net loss was
primarily associated with an increase in net interest income ($295,000) as well
as an increase in non-interest income ($155,000). These increases were offset by
$243,000 in additional other expenses.

   For the six months ended June 30, 1999, the Bank's yield on earning assets
has been 6.80% while the cost of funding sources is 3.69%. While net interest
spread is 3.11%, net interest margin, which considers the effect of non-interest
bearing deposits, was 4.27%, a decrease of 26 basis points as compared to the
same period in the prior year.  Net interest margin is lower than the prior year
as non-interest bearing deposits declined relative to total deposits.  Net
interest income in the aggregate increased for the six months ended June 30,
1999, over the same period for 1998 primarily due to the volume of earning
assets and interest bearing liabilities.  Management monitors the rate
sensitivity of earning assets and interest-bearing liabilities over the entire
life of these instruments, but places particular emphasis on the first year.

   Other income increased approximately $155,000 for the six months ended June
30, 1999, compared to the same period for 1998.  This increase was primarily
associated with an increase in service charges on deposit accounts of
approximately $24,000 related to an increase in the number of accounts and a
$119,000 increase in gains on the sale of SBA loans.

   Other expense increased approximately $240,000 for the six months ended
June 30, 1999, compared to the same period for 1998, primarily due to an
increase in the volume of business, which led to additional expense necessary to
service new business.

Year 2000

The Company utilizes and is dependent upon data processing systems and software
to conduct its business.  The approach of the Year 2000 presents an issue in
that many computer programs have been written using two digits rather than four
to define the applicable year.  Computer programs that have date-sensitive
software may recognize a date using "00" as the year 1900 rather than the Year
2000.  For example, computer systems may compute payment, interest, delinquency
or other amounts important to the operations of the Company based on the wrong
date.  This could result in internal system failure or miscalculation, and also
creates risk for the Company from third parties with whom the Company deals on
financial transactions.

The FDIC has issued guidelines for insured financial institutions with respect
to Year 2000 compliance.  The Company has developed a Year 2000 Readiness plan
based in part on the guidelines and timetables issued by the FDIC. The Company's
Readiness plan focuses on four primary areas:  (1) service providers, (2) in-
house computers and systems located at the Bank's office, (3) third-party and
customer relationships, and (4) contingency planning.  The Company has
designated a Year 2000 Committee, headed by its Cashier/Chief Operating Officer
who is making Year 2000 readiness assessments and remediation where necessary.
The Company has also established a Year 2000 Steering Committee consisting of
its President/CEO and three additional Board members to monitor activities and
to offer support and guidance.

Service Providers.  The Company has identified all mission critical service
providers.  Of the four considered critical, the Company has a detailed plan
written to facilitate testing of mutually transmitted information for three of
them.  As to the fourth, the Company has elected to change to a data processing
company that is well established and is currently using software designated as
compliant.  Conversion to this company occurred during the beginning of the
second quarter of 1999.

The Company is actively communicating with and monitoring the progress of all
providers and vendors to assess the impact of Year 2000 issues on their
companies and their ability to provide products and services.  The Company will
consider new business relationships with alternate providers or vendors if
necessary.

The Company has contracted with a well-known and respected CPA firm to act as
the third party review of all test results.  These CPAs will evaluate the
technical information in these results and offer informed suggestions and or
recommendations.

                                      -9-
<PAGE>

Year 2000, continued

In-house Computers and Systems.  The Company has performed a comprehensive
inventory of all equipment, to include the vaults, computers and systems, such
as security, telephone, heating and air conditioning.  The computers were tested
using software designed for the purpose of determining Year 2000 compliance and
were deemed compliant. The Company contacted the vendors of its equipment and
systems and during testing did not identify any embedded microchips to be
century date sensitive.

Third Party and Customer Relationships. The Company is attempting to maintain
communication with suppliers and vendors to determine the impact of such third
parties' failure to remediate their own Year 2000 issues.  These third parties
include other financial institutions, office supply vendors and telephone,
electric and other utility companies.  The Company is encouraging its customers
to conduct their own Year 2000 assessment and take appropriate steps to become
Year 2000 compliant.

The Company has completed an assessment of its depository and loan relationship
customers.  This assessment process is on going and is a required procedure in
the underwriting of any new commercial loan. Additionally, the Company
encourages its larger and commercial borrowers to assess the potential impact of
Year 2000 on them and their ability to remain current on loan repayments.

Contingency Plans.  As part of the Company's normal business practice, it
maintains contingency plans to follow in the event of emergency situations, some
of which could arise from Year 2000-related problems. The Company has formulated
a detailed Year 2000 contingency plan, which assesses several possible scenarios
to which the Company may be required to react.

Financial Implications.  The Company believes that, since the majority of its
equipment is relatively new, the Year 2000 problem will not pose significant
internal operational problems or generate material additional expenditures.
Maintenance, testing and modification costs will be expensed as incurred.  The
Company does not expect the amounts required to be expensed to resolve Year 2000
issues to have a material effect on its financial position or results of
operations.  The Company currently estimates that the costs of assessing,
testing and remediation of Year 2000 issues will total approximately $50,000.
The anticipated costs associated with the Company's Year 2000 compliance program
do not include time and costs that may be incurred as a result of any potential
failure of third parties to become Year 2000 compliant or costs to implement the
Company's contingency plans.

Potential Risks.  The Year 2000 issue presents a number of risks to the business
and financial condition of the Company and the Bank.  External factors, which
include but are not limited to electric, telephone and water service, are beyond
the control of the Company and the failure of such systems could have a negative
impact on the Company, its customers and third parties on whom the Company
relies for its day-to-day operations.  The business of many of the Company's
customers may be negatively affected by the Year 2000 issue, and any financial
difficulties incurred by the Company's customers in connection with the century
change could negatively affect such customers' ability to repay loans to the
Company.  The failure of the Bank's computer system or applications or those
operated by customers or third parties could have a material adverse effect on
the Company's results of operations and financial condition.

The foregoing are forward-looking statements reflecting management's current
assessment and estimates with respect to the Company's Year 2000 compliance
efforts and the impact of Year 2000 issues on the Company's business and
operations.  Various factors could cause actual plans and results to differ
materially from those contemplated by such assessments, estimates and forward-
looking statements, many of which are beyond the control of the company.  Some
of these factors include, but are not limited to representations by the
Company's vendors, providers, counterparties, technological advances, economic
considerations and consumer perceptions.  The Company's Year 2000 compliance
program is an ongoing process involving continual evaluation and may be subject
to change in response to new developments.
