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

1.    BASIS OF PRESENTATION

      The financial statements included herein have been prepared by Summit
      Bank Corporation and Subsidiaries (the "Company"), 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 furnished 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. These consolidated financial statements should
      be read in conjunction with the Company's audited financial statements
      and the notes thereto as of December 31, 1996, included in the Company's
      Annual Report on Form 10-K for the year ended December 31, 1996.

      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. All intercompany accounts
      and transactions have been eliminated in consolidation.

2.    ACCOUNTING POLICIES

      Reference is made to the accounting policies of the Company 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, 1996.

3.    DERIVATIVES DISCLOSURES

      In January 1997, the Securities and Exchange Commission approved rule
      amendments (the Release) regarding disclosures about derivative financial
      instruments, other financial instruments and derivative commodity
      instruments. The Release requires inclusion in the footnotes to the
      financial statements of extensive detail about the accounting policies
      followed by a registrant in connection with its accounting for derivative
      financial instruments and derivative commodity instruments. The
      accounting policy requirements become effective for all registrants for
      filings that include financial statements for periods ending after
      September 15, 1997. The Company does not presently have any derivative
      financial instruments or derivative commodity instruments as defined in
      the Release.

4.    OTHER BORROWINGS

      The Company has a $16 million credit line with the Federal Home Loan Bank
      on which it drew $10 million in July 1997 for a six month term. This
      advance bears an interest rate of 5.75% and is fully collateralized by
      investment securities owned by the Bank.

5.    STOCKHOLDERS' EQUITY

      The Company issued stock warrants to certain founding shareholders of the
      Company in 1988 which mature in March 1998. The Company recently
      completed a registration with the Securities and Exchange Commission for
      the underlying shares of common stock into which the warrants are
      exercisable. At September 30, 1997, 43,215 of the 463,225 warrants
      originally issued were exercised at the option price of $10 per share,
      resulting in $432,150 additional paid in capital for the Company. The
      remaining warrants, if exercised, will generate up to $4.2 million of
      additional capital for the Company by March 1998.

6.    RECLASSIFICATIONS

      Certain 1996 amounts have been reclassified for comparative purposes in
      order to conform the prior period to the 1997 presentation

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

      For the three-month and nine-month periods ended September 30, 1997 and
      1996 

Performance Overview

Summit Bank Corporation and Subsidiaries (the "Company") reported net income of
$607,000 for the third quarter of 1997, representing a 24% increase over
earnings for the same period last year. The strong earnings improvement for the
quarter is attributed to an increase in interest income resulting primarily
from a higher volume of earning assets. Since September 30, 1996, the Company's
earning assets have grown $15 million, or 12%. Net earnings per share for third
quarter 1997 were $.37 as compared to $.31 for third quarter 1996. Nine-month
earnings for 1997 were $1,676,000 compared to $1,558,000 last year, an increase
of 8%. The annualized return on average stockholders' equity for the nine-month
period ending September 1997 was 12.8% compared to 13.2% for the 1996
nine-month period due to strong equity growth. The return on average assets for
the nine-month period was 1.4% compared to 1.5% in 1996. Book value per share
increased to $12.89 at September 30, 1997, from $12.03 at December 31, 1996.

Net interest income increased 13% in third quarter 1997 to $2 million compared
to the same period last year due to the Company's growth in earning assets. For
the nine month comparable periods, 1997 net interest income also reflected a
sharp increase of 16% to $6 million from $5 million. The Company's net interest
margin through September 30, 1997 declined slightly to 5.34% from 5.54%
compared to last year as a result of an increased volume of time deposits.

Provision for loan losses increased to $135,000 from $99,000 in the respective
third quarters of 1997 and 1996 as loan charge-offs increased in third quarter
of this year. Gross charged-off loans for the nine-months ended September 30,
1997 were $896,000, offset by recoveries of $184,000, resulting in an
annualized net charge-off rate of 1.03% of total loans. Net charge-offs for the
same period of 1996 were .22% of total loans. This year's charge-offs included
three loans which totaled $595,000, or 66% of the total charged off. These
loans were classified as substandard at the end of 1996 and, at that time, had
50% specific reserves allocated for them in the loan loss allowance.

Non-interest income increased sharply by 15%, to $913,000, in third quarter
1997 from $791,000 last year. Improvement in service charges on deposits,
including overdraft and NSF fees, accounted for $29,000 of this increase as the
Company's average non-interest bearing checking deposits grew 22% compared to
the third quarter of last year, coupled with increased service charge rates.
International fee income increased $79,000, or 32%, to $327,000 for third
quarter 1997 compared to the comparable period in 1996. Net gains from sales of
loans accounted for $21,000 of the increase in non-interest income, increasing
to $110,000 during the quarter, up from $89,000 for third quarter last year.
This improvement was the result of a higher volume of loans being sold in third
quarter 1997, $2 million, compared to $1.1 million sold in the same period last
year. For the nine-month comparable periods, non-interest income was relatively
flat at $2,479,000 compared to $2,440,000 last year. The decrease of $122,000
in gains on sales of loans during the nine-month comparable periods, attributed
to fewer cumulative sales of loans, was offset by a strong increase in deposit
service charge and overdraft fees of $98,000 over the comparable 1996
nine-month period. Fees for international banking services also reflected
improvement to $895,000 through September 30, 1997 compared to last year's
total to date of $806,000, an 11% increase, resulting from the Bank's new
business development efforts.

Non-interest expenses increased 9% to $1.8 million in the third quarter of 1997
as compared to the same period last year. This increase was mostly attributed
to higher personnel and operating costs resulting from branch expansion. Total
personnel costs increased $75,000 in 1997 over the comparable 1996 three-month
period and $222,000 over the comparable 1996 nine-month period primarily as a
result of additional staff positions. Equipment expenses did not significantly
increase in third quarter 1997 compared to the same period in 1996, although
equipment purchases, primarily for the new branches, increased year to date
expenses by $97,000 compared to last year. Occupancy expenses increased
$76,000, or 25%, for the nine-month comparable periods, also due mainly to
branch expansion. Other operating expenses only increased 6% for the
three-month period ended September 30, 1997 as compared to the same period in
1996 as a result of normal growth. For the nine-month comparable periods, other
operating expenses increased $318,000, or 21%, in 1997 to $1,819,000. Data
processing and telephone expenses in the


                                  PAGE 6 OF 15

aggregate have increased approximately $77,000 for the nine-month period of
1997 over 1996, also due in large part to the requirements of the additional
branches. Total legal and accounting fees for the year to date 1997 were
$85,000 higher than year to date 1996 fees due in part additional costs
incurred for exploring new business opportunities. The Company's efficiency
ratio for the nine-month period of 1997 was 64% compared to 62% for the same
period last year. Total assets at September 30, 1997 increased to $172 million,
an increase of 22% during the last twelve months and 12% since year end 1996.
Deposits grew to $137 million, reflecting an increase of $17 million, since
September 30, 1996, or 14%, and a $5 million increase since December 31, 1996.
Time deposits have grown $7.5 million since year end while demand deposits have
decreased $3 million. Since opening in 1996, the Bank's two newest branches
have generated a total of $18 million in deposits and have expanded our
presence in Cobb County as well as providing more awareness of our organization
in Gwinnett County. Net loans increased $8.4 million to $92 million at
September 30, 1997, representing a 10% increase since December 31, 1996. During
the last twelve months net loans have increased 12%, or $10 million, from $82
million at September 30, 1996. The Bank originated $9.1 million and $6.6
million in SBA loans during the first nine-months of 1997 and 1996,
respectively, while selling $4.1 million and $3 million of SBA guarantees in
these respective periods. In third quarter 1997, the Company had $10 million
borrowed under an advance from the Federal Home Loan Bank. This advance matures
in January, 1998. Other assets increased to $4.4 million at September 30, 1997
from $2.2 million at year-end 1996 which includes a recorded receivable from
the sale of $2 million in SBA guarantees.

Asset Quality

Non-performing assets increased to $1,996,000 at September 30, 1997 compared to
$922,000 at year end 1996. Non-performing assets represented 2.17% of total
loans as of September 30, 1997 compared to 1.07% at December 31, 1996. While
higher than historic levels, total non-accrual loans at September 30, 1997
included $1,101,000 of loans that are fully guaranteed by the SBA, and one
conventional loan of $746,000 that is fully secured by commercial real estate.
The increase in SBA non-accrual loans is attributed to temporary delays by the
SBA to timely process guarantee liquidations and is not reflective of overall
change in portfolio quality. Six (6) SBA loans in non-accrual status
representing $600,000 are expected to be fully liquidated during fourth quarter
1997. The Company had $1,126,000 of loans 90 days or more past due at September
30, 1997, all of which were on non-accrual status. At September 30, 1996, the
Company had no loans 90 days or more past due.

The allowance for loan losses was $1,614,000 at September 30, 1997 compared to
$1,931,000 at year end 1996, a decrease of 16%. This was as a result of the
recognition of higher net charge-offs for which the Bank had reserved earlier.
As previously mentioned, $595,000 of loans charged off had allocations of 50%
specific reserves prior to January 1, 1997, and $52,000 were fully guaranteed
by the SBA. The allowance for loan losses represented 1.76% of total loans
outstanding at September 30, 1997 compared to 2.30% in 1996. Gross charge-offs
of $896,000 offset by recoveries of $184,000, resulted in a net annualized
charge-off rate of 1.03% of average total loans compared to .22% for the entire
year of 1997.

The loan portfolio is periodically reviewed 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, nonperforming assets, internal credit ratings,
concentrations of credit, and economic trends. Based on this analysis,
management considers the allowance for loan losses at September 30, 1997 to be
adequate to cover possible loan losses in the portfolio as of that date.
However, because of the inherent uncertainty of assumptions made during the
evaluation process, there can be no assurance 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

The liquidity of the Company is primarily dependent on the Bank. Because the
Company's principal operations are conducted throughout the Bank, the Company
generates cash to pay dividends on the Common Stock primarily through dividends
paid to it by the Bank. The Company is also dependent on dividends from the
Bank to service any debt and to conduct other activities. At September 30,
1997, the Company had no outstanding debt. The Bank's ability to pay dividends
to the Company is limited by certain legal and regulatory restrictions. The
Boards of Directors of the Company and the Bank presently intend that earnings
of the Bank will be retained by the Bank during the foreseeable future for the
purpose of enhancing the Bank's capital to support future growth, except to the
extent dividends must be paid to the Company to service its debt and pay its
operating expenses.

Liquidity has fluctuated during 1997 with changes in deposits balances, due in
part to the movement of temporary funds, yet loan growth has been steady. At
September 30, 1997, the Company's net loan to deposit ratio was 67.2%, up from
63.1% at year end. The Bank's liquid assets as a percent of total deposits were
50% at September 30, 1997 compared to 46% at December 31, 1996. 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, available federal funds lines and
short-term borrowings to ensure that no potential shortfall exists.
Additionally, the Bank has $6 million of borrowing capacity under a secured
line of credit available from the Federal Home Loan Bank of Atlanta. Based on
this analysis, management believes that the Company has adequate liquidity to
meet short-term operational requirements.

Stockholders' equity of the Company increased $1.9 million, or 11.2%, to $18.8
million at September 30, 1997, compared to the balance at December 31, 1996 and
increased 16.8% since September 30, 1996. The capital level of the Bank exceeds
all prescribed regulatory capital guidelines. Regulations require that most
highly rated national 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 was 9.5% at September 30, 1997 compared to 9.3% at year
end 1996. 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, 1997, the Bank had a risk-weighted total capital ratio of 16.7%
and a Tier 1 risk-weighted capital ratio of 15.5% which compared favorably to
year-end ratios of 15.6% and 14.2%, respectively.

The Company issued stock warrants to certain founding shareholders of the
Company in 1988 which mature in March 1998. The Company recently completed a
registration with the Securities and Exchange Commission for the underlying
shares of common stock into which the warrants are exercisable. At September
30, 1997, 43,215 of the 463,225 warrants originally issued were exercised at
the option price of $10 per share, resulting in $432,150 additional paid in
capital for the Company. The remaining warrants, if exercised, will generate up
to $4.2 million of additional capital for the Company by March 1998. The Board
and management of the Company are currently pursuing several alternatives for
the best utilization of this capital.
