                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE 1.  NATURE OF BUSINESS AND BASIS OF PRESENTATION

         The consolidated financial information for GBC Bancorp, Inc. (the
         "Company") included herein is unaudited; however, such information
         reflects all adjustments (consisting solely of normal recurring
         adjustments) which are, in the opinion of management, necessary for a
         fair statement of results for the interim period.

         The results of operations for the three and six month periods ended
         June 30, 2000 are not necessarily indicative of the results to be
         expected for the full year.

NOTE 2.  CURRENT ACCOUNTING DEVELOPMENTS

         In June 1998, the Financial Accounting Standards Board issued SFAS No.
         133, "Accounting for Derivative Instruments and Hedging Activities".
         The effective date of this statement has been deferred by SFAS No. 137
         until fiscal years beginning after June 15, 2000. However, the
         statement permits early adoption as of the beginning of any fiscal
         quarter after its issuance. The Company expects to adopt this statement
         effective January 1, 2001. SFAS No. 133 requires the Company to
         recognize all derivatives as either assets or liabilities in the
         balance sheet at fair value. For derivatives that are not designated as
         hedges, the gain or loss must be recognized in earnings in the period
         of change. For derivatives that are designated as hedges, changes in
         the fair value of the hedged assets, liabilities, or firm commitments
         must be recognized in earnings or recognized in other comprehensive
         income until the hedged item is recognized in earnings, depending on
         the nature of the hedge. The ineffective portion of a derivative's
         change in fair value must be recognized in earnings immediately.
         Management does not believe the adoption of SFAS No. 133 will have a
         material effect on the Company's earnings or financial position.

         There are no other recent accounting pronouncements that have had, or
         are expected to have, a material effect on the Company's financial
         statements.

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

         The following is management's discussion and analysis of certain
         significant factors which have affected the financial position and
         operating results of the Company and its bank subsidiary, Gwinnett
         Banking Company (the "Bank"), during the periods included in the
         accompanying consolidated financial statements.

         FORWARD-LOOKING STATEMENTS

         The Company may from time to time make written or oral forward-looking
         statements, including statements contained in the Company's filings
         with the Securities and Exchange Commission and its reports to
         stockholders. Statements made, other than those concerning historical
         information, should be considered forward-looking and subject to
         various risks and uncertainties. Such forward-looking statements are
         made based upon management's belief as well as assumptions made by, and
         information currently available to, management pursuant to "safe
         harbor" provisions of the Private Securities Litigation Reform Act of
         1995. The Company's actual results may differ materially from the
         results anticipated in forward-looking statements due to a variety of
         factors, including governmental monetary and fiscal policies, deposit
         levels, loan demand, loan collateral values, securities portfolio
         values, interest rate risk management, the effects of competition in
         the banking business from other commercial banks, thrifts, mortgage
         banking firms, consumer finance companies, credit unions, securities
         brokerage firms, insurance companies, money market funds and other
         financial institutions operating in the Company's market area and
         elsewhere, including institutions operating through the Internet,
         changes in governmental regulation relating to the banking industry,
         including regulations relating to branching and acquisitions, failure
         of assumptions underlying the establishment of reserves for loan
         losses, including the value of collateral underlying delinquent loans
         and other factors. The Company cautions that such factors are not
         exclusive. The Company does not undertake to update any forward-looking
         statement that may be made from time to time by, or on behalf of, the
         Company.

         LIQUIDITY AND CAPITAL RESOURCES

         As of June 30, 2000, the liquidity ratio of the Company, as determined
         under guidelines established by regulatory authorities, was
         satisfactory. Management considers the Company's liquidity to be
         adequate to meet operating and loan funding requirements. The liquidity
         ratio (i.e. cash, short-term assets and marketable assets divided by
         deposits) for the Company was approximately 27%. As the Company grows,
         management will continue to monitor liquidity and make adjustments as
         deemed necessary.

         At June 30, 2000, the capital ratios of the Company and the Bank were
         adequate based on regulatory minimum capital requirements. The minimum
         capital requirements and the actual capital ratios for the Company and
         the Bank are as follows:

         As the Company continues to grow and the loan portfolio increases, the
         capital ratios will decrease to levels closer to, but still in excess
         of regulatory minimum requirements.

indicating continued strong loan demand and deposit growth in the Company's
primary market area of Gwinnett County, Georgia.

The Company's net interest income increased by $373,000 and $651,000 for the
second quarter and first six months of 2000 as compared to the same periods in
1999. The Company's net interest margin decreased to 6.34% during the first six
months of 2000 as compared to 7.62% for the first six months of 1999 and 7.21%
for the entire year of 1999. The increase in the net interest income is due
primarily to the increased volume of average loans and related loan fees. The
decrease in the net interest margin is due to the increase of securities as a
component of total interest-earning assets which yield less than loans, coupled
with the increase in rates paid on deposits. The average rate paid on deposits
was 5.43% for the first six months of 2000 as compared to 4.82% for the first
six months of 1999 and 4.96% for the entire year of 1999.

The provision for loan losses increased by $127,000 and $134,000 for the second
quarter and first six months of 2000 as compared to the same periods in 1999.
The increase is due to a combination of increased net charge-offs of $40,000 and
overall loan growth, as well as inherent risk in the loan portfolio. Management
does not believe the increases in net charge-offs indicate any significant
negative trend in the overall credit quality of the loan portfolio. The
Company's allowance for loan losses as a percentage of total loans amounted to
1.50% at June 30, 2000 as compared to 1.52% at December 31, 1999. The allowance
for loan losses is maintained at a level that is deemed appropriate by
management to adequately cover all known and inherent risks in the loan
portfolio. Management's evaluation of the loan portfolio includes a continuing
review of loan loss experience, current economic conditions which may affect the
borrower's ability to repay and the underlying collateral value.

Information with respect to nonaccrual, past due and restructured loans is as
follows:

It is the policy of the Bank to discontinue the accrual of interest income when,
in the opinion of management, collection of such interest becomes doubtful. This
status is accorded such interest when (1) there is a significant deterioration
in the financial condition of the borrower and full repayment of principal and
interest is not expected and (2) the principal or interest is more than ninety
days past due, unless the loan is both well-secured and in the process of
collection.

Loans classified for regulatory purposes as loss, doubtful, substandard, or
special mention that have not been included in the table above do not represent
or result from trends or uncertainties which management reasonably expects will
materially impact future operating results, liquidity, or capital resources.
These classified loans do not represent material credits about which management
is aware of any information which causes management to have serious doubts as to
the ability of such borrowers to comply with the loan repayment terms.

Other income increased by $49,000 and $62,000 for the second quarter and first
six months of 2000 as compared to the same periods in 1999, due to increased
service charges on deposit accounts associated with the overall deposit growth
and other miscellaneous fees.

Other expenses increased by $168,000 and $312,000 for the second quarter and
first six months of 2000. Salaries and employee benefits have increased by
$116,000 and $202,000 during these periods due to an increase in the number of
