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

1.   BASIS OF PRESENTATION

     Summit Bank Corporation and Subsidiaries (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., described below. 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 into 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. The consolidated subsidiary is 80% owned by the Company.
     CashMart's business plan is to provide payroll check cashing services,
     unrelated to the bank subsidiary, through several locations throughout
     metropolitan Atlanta. CashMart generates revenues from fees charged to
     customers for cashing payroll checks. The subsidiary currently operates
     from one location in metropolitan Atlanta, occupying leased space inside a
     convenience store.

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. For interim period financial
     statements, enterprises are required to disclose a total for comprehensive
     income in those financial statements. The term "comprehensive income" is
     used in SFAS 130 to describe the total of all components of comprehensive
     income including net income. "Other comprehensive income" refers to
     revenues, expenses, gains, and losses that are included in comprehensive
     income but excluded from earnings under current accounting standards.
     Currently, "other comprehensive income" for the Company consists solely of
     items previously recorded as a component of stockholders' equity under SFAS
     115, "Accounting for Certain Investments in Debt and Equity Securities".
     The Company adopted the interim-period disclosure requirements of SFAS 130
     effective March 31, 1998 and adopted the annual financial statement
     reporting and disclosure requirements of SFAS 130 effective December 31,
     1998.

     Total comprehensive income for the three months ended March 31, 2000 was
     $268,000 compared to $431,000 for the three months ended March 31, 1999.

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

This quarterly report contains forward-looking statements and information
relating to our subsidiaries and us. The words "believes," "expects," "may,"
"will," "should," "projects," "contemplates," "anticipates," "forecasts,"
"intends" or similar terminology identify forward-looking statements. These
statements reflect management's beliefs and assumptions, and are based on
information currently available to management. Because these statements reflect
the current views of management concerning future events, they involve risks,
uncertainties and assumptions. Actual results may differ significantly from the
results discussed in the forward-looking statements. We undertake no obligation
to update publicly any forward-looking statement for any reason, even if new
information becomes available.

PERFORMANCE OVERVIEW

The Company reported net income of $877,000 for the first quarter of 2000,
compared to $622,000 in first quarter of 1999. The 41% increase was largely
attributed to strong loan growth during the last year, which resulted in higher
net interest income in the first quarter of 2000. Net earnings per share for
first quarter 2000 were $.53 (basic and diluted) as compared to $.35 (basic and
diluted) for first quarter 1999. In addition to the increase in net interest
income, the stock repurchase plan completed in 1999 reduced the number of
outstanding shares resulting in an additional $.03 to the earnings per share.
The cost of the repurchased shares is reflected as a reduction to additional
paid-in-capital in the stockholders' equity section of the balance sheet. The
repositioning of the balance sheet last year, i.e., growth of higher yielding
assets, has resulted in a solid increase in core earnings of the Company. The
annualized return on average stockholders' equity for the 2000 three-month
period was 15.5% versus 10.2% for the 1999 three-month period, and the return on
average assets was 1.3% compared to 1.0% in 1999. Book value per share was
$13.89 at March 31, 2000 compared to $13.76 at December 31, 1999 and $13.75 at
March 31, 1999. In first quarter 2000, the Company paid a cash dividend of
$.18 per share compared to $.10 per share for the same period last year,
reflecting an increase of 80%.

Total assets at March 31, 2000 were $278 million, an increase of 9%, or
$22 million, during the last twelve months, although a slight decline of 1% from
December 31, 1999. The small first quarter decline in total assets from December
31, 1999 was due to the increased liquidity in the form of cash and federal
funds sold that were available at year-end in preparation for the century date
change. The excess funds were reduced in January 2000. The twelve-month increase
was largely due to an increase of 26% in the loan portfolio during that period.
Total loans at the end of the current quarter were $169 million. This also
represents a growth of 2%, or $4 million, in loans during the first quarter
of 2000. Investment securities available for sale totaled $68 million at
March 31, 2000 compared to $69 million at December 31, 1999 and $83 million at
March 31, 1999. The decline over the past twelve months is the result of the
Bank reinvesting these funds in higher yielding loans, thus contributing to
a higher net interest margin.

Total deposits have grown $15 million, or 7%, during the last twelve months.
However, total deposits declined in the first quarter of 2000 by $5.6 million
primarily due to maturing Certificates of Deposits ("CD's") held at year-end as
additional funding for the century date change. While most of the CD's issued in
fourth quarter 1999 at higher promotional rates have matured, many of them were
renewed at lower current rates. Despite the decline in total deposits during
first quarter 2000, demand deposits have actually grown to $58 million at
March 31, 2000 from $54 million at December 31, 1999. Demand deposits now
represent over 25% of total deposits. Since March 31, 1999, demand deposits
have increased $8 million, or 15%. The balance in accounts held under overnight
repurchase agreements has also shown a positive growth rate over the past
twelve months, increasing to $12 million at March 31, 2000 from $5 million at
the end of first quarter 1999. The increase is primarily due to the addition
of several new commercial accounts during the past year.

Net interest income significantly increased when comparing the first quarter
of 2000 to the same period in 1999. Through March 31, 2000 and 1999, net
interest income was $3.4 million and $2.6 million, respectively, for an
increase of 32%. The increase was attributed to the increased volume of loans
for the twelve months ended March 31, 2000. The Company's net interest margin
through March 31, 2000 has continued to improve with the higher yielding mix of
earning assets, moving to 5.48% at the end of the current quarter from 4.41%
through March 31, 1999. This improvement is also partially the result of the
rising rate environment during the past few quarters, as well as the attrition
of the promotional CD's issued last year at premium interest rates.

The provision for loan losses increased to $425,000 for the quarter ended
March 31, 2000 compared to $99,000 for the quarter ended March 31, 1999 due
primarily to higher loan volume. Gross charged off loans for the quarter ended
March 31, 2000 totaled $174,000 while recoveries for the period totaled
$182,000, for an annualized net recovery rate of .02% of total loans. This rate
compares favorably to the annualized charge-off rate of .63% for the first
quarter of 1999, although a large portion of the amount charged off last year
was due to the write-down of $154,000 on foreclosed property subsequently
transferred to Other Real Estate Owned.

Non-interest income rose 24% in first quarter 2000 to $1 million compared to
$842,000 in the same period in 1999. The largest contributor to this increase
was a recovery of $183,000 related to a loan loss pre-dating the acquisition of
California Security Bank. Service charge income, including overdraft charges,
improved along with the growth in demand deposits, for a 25% increase to
$318,000 in first quarter 2000 compared to $255,000 during the same period last
year. The Bank's international department has continued to expand its trade
finance transaction volume over the past year, resulting in 24% more fee income,
or a total of $377,000 through March 31 of this year compared to $303,000 during
the first quarter of 1999. There were no sales of SBA-guaranteed loans to date
in 2000, while there was a gain recognized in first quarter 1999 of $79,000.

Although non-interest expenses increased approximately $300,000, or 14%, in the
first quarter of 2000 compared to the same period last year, efforts to control
costs have reduced the rate of increase from year to year. Last year's increase
from first quarter 1998 was 24%. This year salaries and benefits only increased
6% over first quarter last year and equipment costs were flat, comparing first
quarter 2000 to the same period in 1999. Increases in occupancy costs for the
first quarter of 2000 compared to last year through March 31 were minimal. Most
of the increase in non-interest expenses was due to higher data processing,
legal and accounting fees, as well as operating losses, which were up this year
by $41,000, $69,000, $39,000, and $45,000, respectively. A recently renewed
contract with the Bank's third party data processor includes additional savings
over last year, so these costs should stabilize throughout the rest of this
year. The majority of the legal fees during first quarter 2000 were
loan-related. The Company's efficiency ratio for the three-month period of 2000
improved significantly to 61% from 69% for the same period last year, primarily
due to the stronger net interest income this year.

CashMart had a total net operating loss of $3,800 for the first quarter of 2000,
of which $3,000 was recorded for Summit Bank Corporation's portion.

ASSET QUALITY

Non-performing assets decreased to $1,156,000 at March 31, 2000 compared to
$1,289,000 at year-end 1999 and $4,237,000 at March 31, 1999. Non-performing
assets represented .67% of total loans and other real estate owned as of
March 31, 2000 compared to .77% at December 31, 1999. Non-performing loans at
March 31, 2000 consist of one fully guaranteed SBA credit for $387,000, one
partially guaranteed SBA credit for $99,000, of which $84,000 is fully
guaranteed, and a real estate credit for $670,000, for which the Bank believes
it is well secured. Although there were no commercial loans past due 90 days or
more as to principal or interest payments and still accruing at March 31, 2000,

The allowance for loan losses increased to $2,958,000 at March 31, 2000 from
$2,525,000 at year-end 1999, an increase of 17%. The increase was primarily due
to the recent strong growth in our loan portfolio. Loan losses have declined
this year to date compared to first quarter 1999, with gross charge-offs of
$174,000 offset by recoveries of $182,000, resulting in a net annualized
recovery rate of .02% of average total loans. For the first quarter of 1999 the
net annualized charge-off rate was .63%. The allowance for loan losses
represented 1.72% and 1.67%, respectively, of total loans outstanding at
March 31, 2000 and December 31, 1999.

Management periodically 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 March 31, 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 allocations to the allowance will
not be required.

LIQUIDITY AND CAPITAL ADEQUACY

Liquidity has remained fairly stable since the end of 1999. At March 31, 2000,
the Company's average net loan to deposit ratio was 75%, up from 72% at
year-end. Management also analyzes the level of off-balance sheet assets 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. Additionally, the Bank
has $16 million of borrowing capacity under a secured line of credit available
from the Federal Home Loan Bank of Atlanta, of which $10 million was being
utilized at March 31, 2000. Based on this analysis, management believes that the
Company has adequate liquidity to meet short-term operational requirements.
Stockholders' equity of the Company increased $200,000 to $23 million at
March 31, 2000 from December 31, 1999. This total represented a decline of
$915,000, or 4%, from equity at March 31, 1999. Offsetting normal earnings
growth, the stockholders' equity decrease over the past twelve months was due
to the repurchase of common stock under the Company's stock repurchase plan, as
well as to a change in other comprehensive income.

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 remained fairly
stable at 7.7% at March 31, 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 March 31, 2000, the Bank had a
risk-weighted total capital ratio of 12.6% and a Tier 1 risk-weighted capital
ratio of 11.4% 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 March 31, 2000, there were no substantial changes from the interest rate
sensitivity analysis or the market value of portfolio equity for various changes
in interest rate 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 noted 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.
