SUMMIT BANK CORPORATION AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1.    BASIS OF PRESENTATION

      Summit Bank Corporation (the "Company") prepared the consolidated
      financial statements included herein, without audit, pursuant to the rules
      and regulations of the Securities and Exchange Commission. Certain
      information and footnote disclosures normally included in consolidated
      financial statements prepared in accordance with generally accepted
      accounting principles have been omitted, although the Company believes
      that the disclosures are adequate to make the information presented not
      misleading. In the opinion of management, the information in the condensed
      consolidated financial statements reflects all adjustments necessary to
      present fairly the Company's financial position, results of operations and
      cash flows for such interim periods. Management believes that all interim
      period adjustments are of a normal recurring nature. You should read these
      consolidated financial statements in conjunction with the Company's
      audited financial statements and the notes thereto as of December 31,
      1999, included in the Company's Annual Report on Form 10-K for the fiscal
      year ended December 31, 1999.

      The consolidated financial statements include the accounts of the Company
      and its wholly owned subsidiaries, The Summit National Bank (the "Bank")
      and The Summit Merchant Banking Corporation (inactive), as well as an
      80%-owned subsidiary, CashMart, Inc. All intercompany accounts and
      transactions have been eliminated in consolidation.

      The Company primarily operates through one segment, providing a full range
      of banking services to individual and corporate customers through its
      subsidiary bank.

      During 1999, the Company invested $120,000 in a newly created subsidiary,
      CashMart, Inc. ("CashMart"), a check cashing company. In the first quarter
      of 2000, the Company received regulatory approval for and began operation
      of the subsidiary. CashMart's business plan is to provide payroll check
      cashing services through several locations throughout metropolitan
      Atlanta. CashMart generates revenues from fees charged to customers for
      cashing payroll checks. The subsidiary currently operates from three
      locations in metropolitan Atlanta, occupying leased space inside
      convenience stores. CashMart's operations are wholly separate and apart
      from the Bank's operations.

2.    ACCOUNTING POLICIES

      We refer to the Company's accounting policies described in the notes to
      consolidated financial statements contained in the Company's Annual Report
      on Form 10-K for the year ended December 31, 1999.

3.    COMPREHENSIVE INCOME

      Statement of Financial Accounting Standards No. 130, "Reporting
      Comprehensive Income" ("SFAS 130") establishes standards for reporting and
      displaying of comprehensive income and its components in a full set of
      general-purpose financial statements. The primary component of the
      differences between net income and comprehensive income for the Company is
      net unrealized gains and losses on investment securities. The total
      comprehensive income for the nine months ended September 30, 2000 was
      $3,000,000 compared to $827,000 for the nine months ended September 30,
      1999. The total comprehensive income for the three months ended September
      30, 2000 was $1,404,000 compared to a total comprehensive income of
      $641,000 for the three months ended September 30, 1999.

information becomes available.

Performance Overview

The Company reported net income of $1,062,000 for the third quarter of 2000,
compared to $705,000 in the third quarter of 1999. The 51% increase was
attributed to strong interest margins and containment of operating costs. The
net interest margin was 5.71% through September 2000 compared to 5.01% through
September 1999, due primarily to continued loan growth. Average total loans in
the third quarter of 2000 were $182 million compared to $159 million in the
third quarter of 1999. In addition to deposit growth, the Company sold loans and
investments in the third quarter to fund loan growth which contributed to other
income when compared to the same period last year. More details of these sales
are discussed below. Non-interest expenses only increased 5% to $2.6 million in
third quarter 2000 compared to the same quarter in 1999. Net earnings per share
for third quarter 2000 were $.64 (basic and diluted) compared to $.42 (basic and
diluted) for third quarter 1999.

Net earnings for the nine months ended September 30, 2000 were $2,984,000, a 55%
increase over net earnings of $1,920,000 through September 1999. Net earnings
per share for year to date 2000 were $1.80 (basic and diluted) compared to $1.11
(basic and diluted) for the same period in 1999. Consistent with the current
quarter, loan growth was also the main contributing factor in the strong
earnings increase over last year. While non-interest expenses increased 7%
during 2000 compared to the first nine months of 1999, this increase was largely
offset by higher non-interest income. The annualized return on average
stockholders' equity for the 2000 nine-month period was 17.1% versus 10.8% for
the 1999 nine-month period, and the return on average assets was 1.4% compared
to 1.0% in 1999. Book value per share was $15.04 at September 30, 2000 compared
to $13.76 at December 31, 1999 and $13.61 at September 30, 1999. In third
quarter 2000, the Company paid a cash dividend of $.18 per share compared to
$.12 per share for the same period last year.

Total assets at September 30, 2000 were $278 million compared to $256 million at
September 30, 1999, an increase of 8%, although a slight decline from December
31, 1999. Total assets at December 31, 1999 included higher cash and federal
funds sold levels than normal for liquidity purposes in preparation for the
century date change. The excess funds were reduced in January 2000. The
twelve-month increase in assets was largely due to growth in the loan portfolio
during that period. Total loans at the end of the current quarter were $184
million, reflecting a net increase of 3%, or $6 million, during the third
quarter of 2000 and a net increase of 12%, or $20 million, during the past
twelve months. This increase was net of $1.6 million in sales of Small Business
Administration ("SBA") loans. In addition to normal principal paydowns on
mortgage-backed securities, the Company sold $3.7 million of securities to fund
loan growth, as previously mentioned. At September 30, 2000, investment
securities totaled $66 million.

Total deposits have grown $12 million, or 6%, during the last twelve months, and
$3 million, or 1%, during the current quarter. Increases in time deposit
balances more than offset a $2.7 million decline in non-interest-bearing
deposits during third quarter 2000. However, non-interest-bearing demand
deposits were $57 million at September 30, 2000 compared to $50 million at
September 30, 1999. Average non-interest-bearing demand deposits for the year to
date represent over 26% of total deposits, a ratio that is considerably higher
than the Bank's peers. Due to the slower growth rate in deposits than loans, the
Bank increased its other borrowing position with the Federal Home Loan Bank.
Total advances at September 30, 2000 were $17 million compared to $10 million
one year ago. These advances have various maturities, and the rates are
comparable with time deposit rates currently paid by the Bank.

Net interest income increased 16%, or $500,000 in third quarter 2000, compared
to third quarter 1999 to a total of $3.7 million. The increase was due to the
increased volume of loans for the twelve months ended September 30,


                                  Page 6 of 14
<PAGE>   7

2000. For the nine months ended September 30, 2000, net interest income
increased 22% compared to the same period in 1999, also due to strong loan
growth. Also related to this growth, the provision for loan losses for this year
to date was higher than last year by $201,000, for a total provision this year
of $825,000.

Non-interest income increased in third quarter 2000 to $859,000 compared to
$676,000 in the same period in 1999. The primary reason for the increase was due
to the change in net gains on sales of investment securities and SBA loans
during the third quarters of 2000 and 1999. In the third quarter of last year,
$122,000 in losses were recognized on sales of investment securities. During the
current third quarter, the Bank recognized a net gain of $4,000 on asset sales -
$78,000 in gains on sales of SBA loans and $74,000 in losses on sales of
investment securities. The international department of the Bank posted stronger
fee income of 5% in the current quarter compared with third quarter 1999, due to
higher transaction volume. Total international fee income for the year to date
was $1.1 million, a 13% increase over last year to date. There was no variance
in total net gains and losses on asset sales for the year to date. Year to date
non-interest income this year also included recoveries from a loan previously
charged-off in conjunction with the acquisition of California Security Bank in
1998. These recoveries totaled $325,000.

Non-interest expenses during third quarter 2000 were only 5% higher than third
quarter last year, as a result of management's continued efforts to control
costs and improve the overhead efficiency ratio. The increase was mainly due to
salaries and benefits costs, which increased 10% from third quarter last year.
As the labor market continues to tighten, the Bank has experienced its effects
in higher replacement salaries, adjustments to existing salaries to meet
competition and recruitment fees (reported in other operating expenses.)
Variances in equipment, occupancy and other operating expenses comparing the
same quarters were minimal. For the year to date, non-interest expenses
increased 7% over last year to date. In past years, the rate of increase in
non-interest expenses from year to year has been in the double digits. Salaries
and benefits for the year increased approximately $300,000, or 9%, also due to
the tightening labor market. The number of employees on staff at September 30,
2000 compared to one year ago only increased by 2 to 103. For the year to date
through September, the Company's efficiency ratio, defined as non-interest
expenses divided by net interest income plus non-interest income, improved
significantly to 59% from 68% for the same period last year. This was primarily
due to the stronger net interest income this year, as well as the control of
overhead costs.

In the third quarter of 2000, the Company announced a stock repurchase plan
indicating that up to 3%, or 50,000, of the current outstanding shares would be
purchased over the next twelve months. As of September 30, 2000, a total of
5,700 shares had been purchased under this plan at a cost of $89,200. Total
shareholders' equity reflects repurchased shares as a reduction of additional
paid in capital.

CashMart had a total net operating loss of $34,000 for the third quarter of
2000, of which 80%, or $27,000 was recorded as the Company's portion. Net losses
for the year to date through September were $55,000, of which $44,000 was
recorded as the Company's portion. Revenues of CashMart were negligible during
the quarter due to low, albeit building, transaction volume. Operating costs
consisted mainly of personnel costs and lease payments on space and equipment.
The third location opened at the end of October 2000.

Asset Quality

Asset quality has improved significantly this year compared to prior years.
Non-performing loans decreased to $295,000 at September 30, 2000 from $1.3
million at year-end 1999 and $1.7 million at September 30, 1999. Furthermore,
100% of the non-performing loans were fully guaranteed by the SBA. Total
non-performing assets also included the premises that housed the East Marietta
branch office until June 2000. The balance of $595,000 was reclassified as other

The allowance for loan losses increased to $3,136,000 at September 30, 2000 from
$2,525,000 at year-end 1999, an increase of 24%. The continued increase in the
allowance for loan losses reflects continued growth in the loan portfolio and an
overall concern regarding a general softening of the economy in the Company's
market. Loan losses were lower this year compared to the first nine months of
1999, with gross charge-offs of $484,000 offset by recoveries of $270,000,
resulting in a net annualized charge-off rate of .16% of average total loans.
This is a strong improvement over the first nine months of 1999, during which
the net annualized charge-off rate was .45%. The allowance for loan losses
represented 1.71% and 1.67%, respectively, of total loans outstanding at
September 30, 2000 and December 31, 1999.

Management regularly analyzes our loan portfolio to evaluate the outstanding
loans and to measure both the performance of the portfolio and the adequacy of
the allowance for loan losses. This analysis includes a review of delinquency
trends, actual losses and internal credit ratings. Based on this analysis,
management considers the allowance for loan losses at September 30, 2000 to be
adequate to cover loan losses in the portfolio as of that date. However, because
of the inherent uncertainty of the assumptions we use in our loan analyses,
management cannot assure that loan losses in future periods will not exceed the
allowance for loan losses or that additional increases to the allowance will not
be required.

Liquidity and Capital Adequacy

Liquidity has decreased in the past few months as the growth rate for loans has
exceeded that of deposits. At September 30, 2000, the Company's average net loan
to average deposit ratio was 79%, up from 72% at year-end. The loan to deposit
ratio at September 30, 2000 was 81% compared to 77% at September 30, 1999. The
Bank has $25 million of borrowing capacity under a secured line of credit
available from the Federal Home Loan Bank of Atlanta, of which $17 million was
being utilized at September 30, 2000, up from $10 million at June 30, 2000. A
total of $5.3 million in investment securities and SBA loans were sold in
September to fund higher yielding loans. Management also analyzes the level of
off-balance sheet assets and liabilities such as unfunded loan commitments and
outstanding letters of credit as they relate to the levels of cash, cash
equivalents, liquid investments, and available federal funds lines to ensure
that no potential shortfall exists. Based on this analysis, management believes
that the Company has adequate liquidity to meet short-term operational
requirements.

Stockholders' equity of the Company increased $1 million during third quarter
2000, to $25 million. This total also represented an increase of $2 million from
equity at September 30, 1999. The increase was due to normal earnings growth
since the amount to date of the repurchase of common stock under the Company's
current stock repurchase plan was minimal. Other comprehensive income increased
as well due to earnings during the trailing twelve months.

The capital level of the Bank exceeds all prescribed regulatory capital
guidelines. Regulations require that the most highly rated banks maintain a
minimum Tier 1 leverage ratio of 3% and require other banks to maintain a
minimum Tier 1 leverage ratio of 3% plus an additional cushion of at least 1 to
2 percentage points. Tier 1 capital consists of stockholders' equity less
certain intangible assets. The Bank's Tier 1 leverage ratio increased to 8.4% at
September 30, 2000 compared to 7.6% at year-end 1999. Regulations require that
the Bank maintain a minimum total risk weighted capital ratio of 8% with 50%, or
4%, of this amount made up of Tier 1 capital. Risk-weighted assets consist of
balance sheet assets adjusted by risk category and off-balance sheet asset
equivalents similarly adjusted. At September 30, 2000, the Bank had a
risk-weighted total capital ratio of 12.9% and a Tier 1 risk-weighted capital
ratio of 11.7% which compares favorably to year end 1999 ratios of 12.5% and
11.2%, respectively.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of September 30, 2000, there were no substantial changes from the interest
rate sensitivity analysis or the market value of portfolio equity for various
changes in interest rates calculated as of December 31, 1999. The foregoing
disclosures related to the market risk of the Company should be read in
conjunction with the Company's audited consolidated financial statements,
related notes and management's discussion and analysis of financial condition
and results of operations for the year ended December 31, 1999 included in the
Company's 1999 Annual report on Form 10K.
