                                   (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 month period ended March 31, 2006
     are not necessarily indicative of the results to be expected for the full
     year.

NOTE 3. STOCK-BASED COMPENSATION PLAN

     At March 31, 2005, the Company has a stock-based compensation plan that
     includes employees and directors. Prior to January 1, 2006, the Company
     accounted for the plan under the recognition and measurement provisions of
     APB Opinion No. 25, Accounting for Stock Issued to Employees, and related
     interpretations, as permitted by FASB Statement No. 123, Accounting for
     Stock-Based Compensation. No stock-based employee compensation cost was
     recognized in the Statement of Operations for the three months ended March
     31, 2005, as all options granted under the plan had an exercise price equal
     to the market value of the underlying common stock on the date of grant.
     Effective January 1, 2006, the Company adopted the fair value recognition
     provisions of FASB Statement No. 123(R), Share-Based Payment, using the
     modified-prospective-transition method. Under that transition method,
     compensation cost recognized includes: (a) compensation cost for all
     share-based payments granted prior to, but not yet vested as of January 1,
     2006, based on the grant date fair value estimated in accordance with the
     original provisions of Statement 123, and (b) compensation cost for all
     share-based payments granted subsequent to January 1, 2006, based on the
     grant-date fair value estimated in accordance with the provisions of
     Statement 123(R). No stock options were granted or no previously granted
     options vested during the three months ended March 31, 2006 or 2005,
     therefore no compensation cost was recognized. The adoption of this
     provisions of Statement 123 (R) did not have a material affect on the
     financial statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

The following is management's discussion and analysis of certain significant
factors which have affected the financial position and operating results of GBC
Bancorp, Inc. and its bank subsidiary, Gwinnett Banking Company, during the
periods included in the accompanying consolidated financial statements. The
purpose of this discussion is to focus on information about our financial
condition and results of operations that are not otherwise apparent from our
unaudited consolidated financial statements as of and for the three months ended
March 31, 2006. Reference should be made to those financial statements for an
understanding of the following discussion and analysis.

FORWARD-LOOKING STATEMENTS

We may from time to time make written or oral forward-looking statements,
including statements contained in our filings with the Securities and Exchange
Commission and 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. Our 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 our 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 allowance for loan losses,
including the value of collateral underlying delinquent loans and other factors.
We caution that such factors are not exclusive. We do not undertake to update
any forward-looking statements that may be made from time to time by, or on our
behalf.

OVERVIEW

Our results for the first quarter of 2006 were highlighted by continued
increased profitability to approximately $1,570,000, compared to approximately
$1,236,000 for the first quarter of 2005, along with continued quality growth of
over $38 million in total assets during the quarter.

CRITICAL ACCOUNTING POLICIES

We have adopted various accounting policies which govern the application of
accounting principles generally accepted in the United States in the preparation
of our financial statements. Our significant accounting policies are described
in the footnotes to the consolidated financial statements at December 31, 2005,
as filed in our annual report on Form 10-KSB.


                                      -8-

<PAGE>

Certain accounting policies involve significant judgments and assumptions by us
which have a material impact on the carrying value of certain assets and
liabilities. We consider these accounting policies to be critical accounting
policies. The judgments and assumptions we use are based on historical
experience and other factors, which we believe to be reasonable under the
circumstances. Because of the nature of the judgments and assumptions we make,
actual results could differ from these judgments and estimates which could have
a material impact on our carrying values of assets and liabilities and our
results of operations.

We believe the allowance for loan losses is a critical accounting policy that
requires the most significant judgments and estimates used in preparation of our
consolidated financial statements. Please see the portion of this discussion
that addresses our allowance for loan losses for a description of our processes
and methodology for determining our allowance for loan losses.

LIQUIDITY AND CAPITAL RESOURCES

The purpose of liquidity management is to ensure that there are sufficient cash
flows to satisfy demands for credit, deposit withdrawals, and our other needs.
Traditional sources of liquidity include asset maturities and growth in core
deposits. A company may achieve its desired liquidity objectives from the
management of assets and liabilities and through funds provided by operations.
Funds invested in short-term marketable instruments and the continuous maturing
of other earning assets are sources of liquidity from the asset perspective. The
liability base provides sources of liquidity through deposit growth, the
maturity structure of liabilities, and accessibility to market sources of funds.

Scheduled loan payments are a relatively stable source of funds, but loan
payoffs and deposit flows fluctuate significantly, being influenced by interest
rates and general economic conditions and competition. We attempt to price
deposits to meet asset/liability objectives consistent with local market
conditions.

Our liquidity is monitored on a periodic basis by management and State and
Federal regulatory authorities. We monitor our liquidity requirements under two
categories, operational needs and emergency needs. The operational needs
category establishes the cash requirements to sufficiently fund our deposit
reserve requirements and pay operating expenses. The emergency need category
establishes sufficient cash requirements to fund the volatility of deposits. As
determined under these categories, our liquidity as of March 31, 2006 was
considered satisfactory.

In the future, the primary source of funds available to us will be the payment
of dividends by the Bank. Banking regulations limit the amount of the dividends
that may be paid without prior approval of the Bank's regulatory agency.
Currently, the Bank could pay approximately $3,100,000 dividend without
regulatory approval.

At March 31, 2006, our capital ratios were adequate based on regulatory minimum
capital requirements. The minimum capital requirements and the actual capital
ratios on a consolidated and bank-only basis are as follows:


                                      -9-

                             CONSOLIDATED    BANK   REQUIREMENT
                             ------------   -----   -----------
<S>                          <C>            <C>     <C>
Leverage capital ratios          8.81%       8.53%      5.00%
Risk-based capital ratios:
   Core capital                  9.65%       9.35%      6.00%
   Total capital                 9.78%      10.48%     10.00%
</TABLE>

These ratios may decline as asset growth continues, but are expected to exceed
regulatory minimum requirements. We believe that anticipated future earnings
will assist in keeping these ratios at satisfactory levels.

OFF-BALANCE SHEET ARRANGEMENTS

We are a party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of our customers. These
financial instruments include commitments to extend credit and standby letters
of credit. Such commitments involve, to varying degrees, elements of credit risk
and interest rate risk in excess of the amount recognized in the balance sheet.

Our exposure to credit loss in the event of nonperformance by the other party to
the financial instrument for commitments to extend credit and standby letters of
credit is represented by the contractual amount of those instruments. We use the
same credit policies in making commitments and conditional obligations as we do
for on-balance sheet instruments. A summary of our commitments is as follows:

<TABLE>
<CAPTION>
                                 MARCH 31,
                                   2006
                               ------------
<S>                            <C>
Commitments to extend credit   $141,831,436
Letters of credit                 4,993,607
                               ------------
                               $146,825,043
                               ============
</TABLE>

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Since many
of the commitments are expected to expire without being drawn upon, the total
commitment amounts do not necessarily represent future cash requirements. The
amount of collateral obtained, if deemed necessary by us upon extension of
credit, is based on our credit evaluation of the customer.

Standby letters of credit are conditional commitments issued by us to guarantee
the performance of a customer to a third party. Those letters of credit are
primarily issued to support public and private borrowing arrangements. The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loans to customers. Collateral is required in
instances which we deem necessary.


                                      -10-

RELATED PARTY TRANSACTIONS

We lease our main office banking facilities under a noncancelable operating
lease agreement from GBC Properties, LLC, a limited liability company formed by
our organizers. The lease term is for 15 years with the monthly rental payment
adjusting every fifth year for changes in the Consumer Price Index. The lease
agreement requires us to pay normal operating and occupancy expenses of the
facilities.

Our total assets increased by 10.17% for the first three months of 2006. Deposit
growth of approximately $34,259,000 was invested primarily in the interest
earning categories of loans and federal funds sold. Our net loan to deposit
ratio has increased to 92.77% at March 31, 2006 from 92.46% at December 31,
2005. Our total equity increased by year-to-date net income of approximately
$1,570,000 and decreased by an unrealized loss on securities available-for-sale,
net of tax, of approximately $123,000.

Our securities portfolio, consisting of U.S. Agency, State, County and
Municipals, and mortgage-backed securities, amounted to approximately
$32,114,000 at March 31, 2006. Unrealized losses on securities amounted to
approximately $876,000 at March 31, 2006, as compared to an unrealized loss of
approximately $705,000 at December 31, 2005. Management has not specifically
identified any securities for sale in future periods that, if so designated,
would require a charge to operations if the market value would not be reasonably
expected to recover prior to the time of sale.

We have 80% of our loan portfolio collateralized by real estate located in our
primary market area of Gwinnett County, Georgia and surrounding counties. Our
real estate construction portfolio consists of loans collateralized by loans to
build one-to-four-family residential properties. We generally require that loans
collateralized by real estate not exceed 80%-85% of the collateral value.

The remaining 20% of the loan portfolio consists of commercial, consumer, and
other loans. We require collateral commensurate with the repayment ability and
creditworthiness of the borrower.

The specific economic and credit risks associated with our loan portfolio,
especially the real estate portfolio, include, but are not limited to, a general
downturn in the economy which could affect unemployment rates in our market
area, general real estate market deterioration, interest rate fluctuations,
deteriorated or non-existing collateral, title defects, inaccurate appraisals,
financial deterioration of borrowers, fraud, and any violation of banking
protection laws. Construction lending can also present other specific risks to
the lender such as whether the builders can obtain financing for the
construction, whether the builders can sell the home to a buyer, and whether the
buyer can obtain permanent financing. Currently, real estate values and
employment trends in our market area are stable with no indications of a
significant downturn in the local economy.

We attempt to reduce these economic and credit risks not only by adhering to
loan to value guidelines, but also by investigating the creditworthiness of the
borrower and monitoring the borrower's financial position. Also, we establish
and periodically review our lending policies and procedures as well as having
independent loan review. State banking regulations limit exposure by prohibiting
secured loan relationships that exceed 25% of the Bank's statutory capital and
unsecured loan relationships that exceed 15% of the Bank's statutory capital.

</TABLE>

Our net interest income increased by approximately $1,128,000 for the first
three months of 2006 as compared to the same periods in 2005. Our net interest
margin increased to 4.79% during the first three months of 2006 as compared to
4.66% for the first three months of 2005. The increase in net interest income is
due primarily to the increased volume of average loans, the increase in prime
interest rate and related loan fees. The increase in the net interest margin is
due to the increase in the prime interest rate along with a smaller increase in
cost of funds. Our cost of funds increased to 4.10% in the first three months of
2006 as compared to 2.79% in the first three months of 2005.

The provision for loan losses increased by approximately $195,000 for the first
three months of 2006 as compared to the same periods in 2005. The amounts
provided are due primarily to overall loan growth, as well as our assessment of
the inherent risk in the loan portfolio. Based upon our evaluation of the loan
portfolio, we believe the allowance for loan losses to be adequate to absorb
losses on existing loans that may become uncollectable. Our evaluation considers
significant factors relative to the credit risk and loss exposure in the loan
portfolio, including past due and classified loans, past experience, underlying
collateral values, and current economic conditions that may affect the
borrower's ability to repay. The allowance for loan losses is evaluated by
segmenting the loan portfolio into unclassified and classified loans. The
unclassified loans are further segmented by loan type with an allowance
percentage applied to each type in order to establish a general allowance for
loan losses. The allowance percentage determined is based upon our experience
specifically and the historical experience of the banking industry generally.
Due to improvements in the economic environment, the historical experience of
low losses and the maturing of the loan portfolio, management may decrease the
general allowances for loan losses in the future. The classified loans,
including impaired loans, are analyzed individually in order to establish a
specific allowance for losses. The allowance for loan losses as a percentage of
total loans was 1.16% at March 31, 2006 as compared to 1.16% at December 31,
2005.

Potential problem loans are defined as loans about which we have serious doubts
as to the ability of the borrower to comply with the present loan repayment
terms and which may cause the loan to be placed on nonaccrual status, to become
past due more than ninety days, or to be restructured.

It is our policy to discontinue the accrual of interest income when, in the
opinion of management, collection of interest becomes doubtful. This status is
accorded 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 decreased by approximately $254,000 for the first three months of
2006 as compared to the same periods in 2005. Decreased gain on sale of loans of
approximately $361,000 created the year-to-date decrease. The decrease is due to
a provisional decreased activity in the Small Business Administration (SBA) loan
program during the first quarter of 2006.

Other expenses increased by approximately $138,000 for the first three months of
2006 as compared to the same periods in 2005. Salaries and employee benefits
have increased by approximately $185,000 during this period due to an increase
in the number of full time equivalent employees to 46 as of March 31, 2006 from
42 as of March 31, 2005, and to other annual salary increases. Equipment and
occupancy expenses decreased by $32,000 due to the renewed lease contract
included free rent for first six months of 2006. Other operating expenses have
decreased by approximately $15,000, during this period due to a decrease in
professional fees.

We have provided for income taxes at an effective tax rate of 37% for the first
three months of 2006 as compared to 36% for the first three months of 2005.

We are not aware of any known trends, events or uncertainties, other than the
effect of events as described above, that will have or that are reasonably
likely to have a material effect on our liquidity, capital resources or
operations. We are also not aware of any current recommendations by the

ITEM 3. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, we carried out an
evaluation, under the supervision and with the participation of our Chief
Executive Officer and the Chief Financial Officer, of the effectiveness of the
design and operation of our disclosure controls and procedures in accordance
with Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). Based on this evaluation, our Chief Executive and Chief
Financial Officer concluded that our disclosure controls and procedures are
effective for gathering, analyzing and disclosing the information that we are
required to disclose in the reports we file under the Exchange Act, within the
time periods specified in the SEC's rules and forms. Our Chief Executive Officer
and Chief Financial Officer also concluded that our disclosure controls and
procedures are effective in timely alerting them to material information
relating to our company required to be included in our periodic SEC filings. In
connection with the new rules, we are in the process of further reviewing and
documenting our disclosure controls and procedures, including our internal
controls and procedures for financial reporting, and may from time to time make
changes designed to enhance their effectiveness and to ensure that our systems
evolve with our business.

There have been no significant changes in our internal control over financial
reporting that occurred during the period covered by this report that have
materially affected, or are reasonably likely to materially affect, our internal
control over financial reporting.
