ITEM 1. BUSINESS

     Summit Bancshares, Inc. (the "Company") is a one-bank holding company
registered under the Bank Holding Company Act of 1956, as amended.  It was
incorporated under the laws of the State of California on July 22, 1981.  Its
principal office is located at 2969 Broadway, Oakland, California 94611, and its
telephone number is (510) 839-8800.

     The Bank's main branch is located at 2969 Broadway, Oakland, California
94611 the telephone number is (510) 839-8800.  In addition, the Bank has full
service branches located at 1700 N. Main, Walnut Creek, California 94598. The
telephone number is (925) 935-9220.  An additional full service branch is
located at Watergate III Tower at 2000 Powell Street, Emeryville, California
94608.  The telephone number is (510) 428-1868.  Also, on January 28, 1998, the
Bank opened a new full service branch at 5820 Stoneridge Mall Road, Suite 100,
Pleasanton, California 94588 which moved to new quarters located at 5673 W. Las
Positas Blvd. Ste. 208, Pleasanton, California, 94588 in July of 1998.  The
telephone number is (925) 224-7788.

     Summit Bancshares, Inc. owns all of the capital stock of Summit Bank (the
"Bank"), its subsidiary bank, and its activities during 1998 were limited to
acting as the Bank's holding company.

     The Bank has conducted the business of a commercial bank since July 1, 
1982.  The Bank provides commercial credit and other banking services to 
small and mid-sized businesses and professionals, including professional 
firms of physicians, attorneys, accountants, retailers and service firms, 
wholesalers and distributors.  Because of the concentration of medical 
facilities and related organizations, the growth of real estate opportunities 
and commercial/industrial businesses in the Bank's service area, the Bank 
primarily focuses its marketing efforts on health service businesses, real 
estate construction and commercial industrial loans; however, the Bank also 
offers a broad spectrum of financial services to the business community at 
large.  The Bank offers various checking and savings accounts for both 
personal and business purposes, time 

                                          3
<PAGE>

certificates of deposit, cashier's checks, money orders, travelers checks, 
safe deposit boxes, installment collection services, night depository, 
depository pickup and courier services, telephone transfers, collection 
services for notes, Individual Retirement and Business Planning (formerly 
Keogh) Accounts.  The Bank has not requested and does not have regulatory 
approval to offer trust services, although it may provide such services in 
the future.  The Bank assists customers requiring services not offered by the 
Bank in obtaining such services from its correspondent banks and other 
financial services firms.  Although the Bank does not actively solicit 
consumer business from the general public, it does offer banking services and 
facilities compatible with the need of its consumer customers.

     The Oakland and Emeryville branches of the Bank offer all of the services. 
The banking offices in Walnut Creek and Pleasanton offer the same services
listed above, with the exception of safe deposit boxes.  

     On March 30, 1989, the State Banking Department approved the Bank's 
application to establish a new subsidiary, Summit Equities, Inc, whose 
purpose is to engage in real property investment activities as authorized by 
Section 751.3 of the California Financial Code.  On November 13, 1992 the 
FDIC imposed regulations limiting real estate investment to those authorized 
by national banks, thus no real estate transactions are allowed to be 
transacted under this subsidiary.  The corporation is exploring other avenues 
or types of approved investment activities.  As of this date, the subsidiary 
has not conducted any business.

SERVICE AREA

     The primary geographic market served by the Bank is considered to be all of
Alameda County and most of Contra Costa County, except several cities and
sparsely populated areas in the northern and easternmost sections. The excluded
areas are Pinole, Hercules, Rodeo, Crockett, Port Costa, West Pittsburg and
cities east of it and the sparsely populated areas east of Mt. Diablo.  The
areas served by the Bank include a substantial number of commercial businesses,
a large health services complex and substantial residential population.  In
Alameda County, the health services complex includes three major hospitals,
approximately 432 physicians and a wide variety of health related and other
professionals, and small and medium-sized businesses.  Contra Costa County
includes three major hospitals, approximately 410 physicians some of which are
also affiliated with the hospitals in Alameda County and other professionals and
small and medium-sized businesses.

     The Walnut Creek office is about 16 miles northeast of the head office 
in Oakland and located in the central business district in Walnut Creek.  The 
site is approximately one mile west of John Muir Hospital, which is a 343-bed 
hospital employing approximately 1200 people and accommodates a large staff 
of approximately 290 visiting physicians.  The surrounding service area 
includes 4 convalescent hospitals, an acute psychiatric care facility, and 
the 204-bed Kaiser Foundation Hospital, which employs over 1000 people in 
downtown Walnut Creek and is staffed by approximately 89 physicians.

     The Emeryville office is a further extension of the Bank's plan to expand
into areas, which will further utilize specialized services directed at
medium-sized businesses 


                                          4
<PAGE>

and professionals.  Located west of Interstate 80 at 2000 Powell Street, it
services a commercial sector and an up-scale employee population.

     The Pleasanton office is about 30 miles southeast of the head office in
Oakland and located in a commercial development known as Hacienda Industrial
Park in the city of Pleasanton. It is also two blocks from Valleycare Medical
Center.

     The Bank also obtains business clients from the various areas within the
city of Oakland, adjacent to the John Muir and Kaiser areas of Walnut Creek, and
in the industrial and commercial areas of Emeryville and Pleasanton.  The Bank's
customers are primarily business and professional persons working in the
vicinity of each branch, officers and employees of businesses and professional
firms serviced by the Bank, and residents of areas close to the Bank.

COMPETITION

     The banking business in the Oakland/East Bay metropolitan area is very
competitive with respect to both loans and deposits, and is dominated by
relatively few major banks which have offices operating throughout California. 
Among the advantages such banks have are their ability to finance wide-ranging
advertising campaigns, to offer certain services (for example, trust services)
which are not offered directly by the Bank, and to have substantially higher
legal lending limits due to their greater capitalization.  There are eleven
other independent banks in Oakland, Walnut Creek, Pleasanton, and none in
Emeryville. 

     In competing for deposits, the Bank is subject to certain limitations not
applicable to non-bank financial institution competitors.  Over the past years,
legislative changes have enabled the Bank to compete more effectively for
deposits with savings and loan institutions, but the Bank still remains at a
competitive disadvantage when competing with money market funds.

     To compete with major financial institutions and other independent banks 
in its primary service areas, the Bank relies upon the experience of its 
executive officers in serving business clients, its specialized services, 
local promotional activity, and personal contacts by its officers, directors, 
and employees of the Company.  For customers whose loan demands exceed the 
Bank's legal lending limit, the Bank arranges for such loans on a 
participation basis with correspondent banks as well as other independent 
banks.

REGULATION AND SUPERVISION

     THE COMPANY.  The Company is a bank holding company within the meaning 
of the Bank Holding Company Act of 1956, as amended (the "BHC Act"), and is 
registered as such with the Federal Reserve Board ("FRB").  A bank holding 
company is required to file with the FRB annual reports and other information 
regarding its business operations and those of its subsidiaries.  It is also 
subject to examination by the FRB and is required to obtain FRB approval 
before acquiring, directly or indirectly, ownership or control of any voting 
shares of any bank, if after such acquisition, it would directly or 
indirectly own or control more than 5% of the voting stock of that bank.  The 
BHC Act further provides that the FRB shall not approve any such acquisition 
that would result in or further the creation of a monopoly, or the effect of 
which may be to substantially lessen competition, 

                                          5
<PAGE>

unless the anti competitive effects of the proposed transaction are clearly
outweighed by the probable effect in meeting the convenience and needs of the
community to be served.

     Furthermore, under the BHC Act, a bank holding company is, with limited
exceptions, prohibited from (i) acquiring direct or indirect ownership or
control of more than 5% of the voting shares of any company which is not a bank,
or (ii) engaging in any activity other than managing or controlling banks.  With
the prior approval of the FRB, however, a bank holding company may own shares of
a company engaged in activities which the FRB has determined to be so closely
related to banking or managing or controlling banks as to be a proper incident
thereto.

     The FRB has by regulation determined that certain activities are so closely
related to banking as to be a proper incident thereto within the meaning of the
BHC Act.  These activities include, but are not limited to: operating an
industrial loan company, industrial bank, Morris Plan Bank, savings association,
mortgage company, finance company, credit card company or factoring company;
performing certain data processing operations; providing investment and
financial advice; operating as a trust company in certain instances, selling
traveler's checks, United States savings bonds and certain money orders;
providing certain courier services; providing management consulting advice to
nonaffiliated depository institutions in some instances; acting as insurance
agent for certain types of credit-related insurance; leasing property or acting
as agent, broker or advisor for leasing property on a "full pay-out basis";
acting as a consumer financial counselor, including tax planning and return
preparation; performing futures and options advisory services, check guarantee
services and discount brokerage activities; operating a collection or credit
bureau; or performing personal property appraisals.  The Company has no present
intention to engage in any of such permitted activities at this time.

     The FRB also has determined that certain activities are not so closely
related to banking to be a proper incident thereto within the meaning of the BHC
Act.  Such activities include: real estate brokerage and syndication; land
development; property management; underwriting of life insurance not related to
credit transactions; and with certain exceptions, securities underwriting and
equity funding.  In the future, the FRB may add or delete from the list of
activities permissible for bank holding companies.  Under the BHC Act, a bank
holding company and its subsidiaries are prohibited from acquiring any voting
shares of or interest in all or substantially all of the assets of any bank
located outside the state in which the operations of the bank holding company's
banking subsidiaries are principally conducted, unless the acquisition is
specifically authorized by the law of the state in which the bank to be acquired
is located or unless the transaction qualifies under federal law as an
"emergency interstate acquisition" of a closed or failing bank.  The California
interstate banking bill is described under "Interstate Banking" (below). 

     A bank holding company and its subsidiaries are prohibited from certain
tie-in arrangements in connection with any extension of credit, sale or lease of
a property or furnishing of services.  For example, with certain exceptions, a
bank may not condition an extension of credit on a promise by its customer to
obtain other services provided by it, its holding company or other subsidiaries,
or on a promise by its customer not to obtain other services from a competitor. 
In addition, federal law imposes certain restrictions on transactions between
the Company and its subsidiaries, including the 


                                          6
<PAGE>

Bank.  As an affiliate of the Bank, the Company is subject, with certain
exceptions, to provisions of federal law imposing limitations on, and requiring
collateral for, extensions of credit by the Bank to its affiliates.

     Directors of the Company, and the companies with which they are associated,
have had and will continue to have banking transactions with the Bank in the
ordinary course of the Bank's business.  It is the firm intention of the Company
that any loans and commitments to loan included in such transactions be made in
accordance with applicable law, on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with other persons of similar creditworthiness, and on terms not
involving more than the normal risk of collectability or presenting other
unfavorable features.  At December 31, 1998, loans to directors totaled $366,000
or 2.6% of the Company's shareholders' equity. 
     
     THE BANK.  The Bank is a member of the Federal Deposit Insurance 
Corporation ("FDIC"), which currently insures the deposits of each member 
bank to a maximum of $100,000 per depositor.  For this protection, the Bank 
pays a semi-annual assessment and is subject to the rules and regulations of 
the FDIC pertaining to deposit insurance and other matters.

     The Bank is subject to regulation, supervision and regular examination by
the California State Banking Department (the "Department").  Although the Bank
is not a member of the Federal Reserve System, it is subject to regulation,
supervision, but not examination by the FRB.  The regulations of these agencies
govern most aspects of the Bank's business, including the making of periodic
reports by the Bank and the Bank's activities, branching, mergers and
acquisitions, reserves against deposits and numerous other areas.

     Subject to the regulations of the California Superintendent of Banks (the
"Superintendent"), the Bank may invest in capital stock, obligations or other
securities of other corporations, provided such corporations are not insurance
companies, agents or brokers.  In addition, the Bank may acquire any or all of
the securities of a company that engages in activities that the Bank may engage
in directly under California law without the prior approval of the FRB. 
California state-chartered banks are also specifically authorized to provide
real estate appraisal services, management consulting and advisory services and
electronic data processing services. 

     The Company's primary source of income (other than interest earned on
company capital) is the receipt of dividends and management fees from the Bank. 
The ability of the Bank to pay management fees and dividends to the Company and
its affiliates is subject to restrictions set forth in the California Financial
Code and, under certain circumstances, is subject to approval of the Department.
The board of directors of a state-chartered bank may declare a dividend out of
so much of net profits as such board deems appropriate, subject to California
law which restricts the amount available for cash dividends to the lesser of
retained earnings or the bank's net income less cash dividends paid for its last
three fiscal years.

     In the event that a bank has no retained earnings or net income for the
prior three fiscal years, cash dividends may be paid out of net income for such
bank's last preceding fiscal year or current fiscal year upon the prior approval
of the Department.  Although there are not specific regulations restricting
dividend payments by bank holding companies other than state corporation law,
supervisory concern focuses on the holding 


                                          7
<PAGE>

company's capital position, its ability to meet its financial obligations as
they come due and the capacity to act as a source of financial strength to its
subsidiary banks.

     The FRB and the Superintendent have authority to prohibit a bank from
engaging in business practices, which are considered to be unsafe or unsound. 
Depending upon the financial condition of the Bank and upon other factors, the
FRB or Superintendent could assert that the payments of dividends or other
payments by the Bank to the Company might be such an unsafe or unsound practice.
Also, if the Bank were to experience either significant loan losses or rapid
growth in loans or deposits, or some other event resulting in a depletion or
deterioration of the Bank's capital account were to occur, the Company might be
compelled by federal banking authorities to invest additional capital in the
Bank necessary to return the capital account to a satisfactory level.

     IMPACT OF ECONOMIC CONDITIONS AND MONETARY POLICIES.  The earnings and
growth of the Company are and will be affected by general economic conditions,
both domestic and international, and by the monetary and fiscal policies of the
United States Government and its agencies, particularly the FRB.  One function
of the FRB is to regulate the national supply of bank credit in order to
mitigate recessionary and inflationary pressures.  Among the instruments of
monetary policy used to implement those objectives are open market transactions
in United States Government securities and changes in the discount rate on
member bank borrowings.  The monetary policies of the FRB have had a significant
effect on the operating results of commercial banks in the past and are expected
to continue to do so in the future.  However, the effect, if any, of such
policies on the future business and earnings of the Company cannot be accurately
predicted.


     LEGISLATION AND PROPOSED CHANGES.  From time to time, legislation is
enacted which has the effect of increasing the cost of doing business, limiting
or expanding permissible activities or affecting the competitive balance between
banks and other financial institutions.  Proposals to change the laws and
regulations governing the operations and taxation of banks, bank holding
companies and other financial institutions are frequently made in Congress, in
the California legislature and before various bank regulatory agencies.  No
prediction can be made as to the likelihood of any major changes or the impact
such changes might have on the Company.  Certain changes of potential
significance to the Company which have been enacted recently or others which are
currently under consideration by Congress or various regulatory or professional
agencies are discussed below.

     FINANCIAL INSTITUTIONS REFORM, RECOVERY AND ENFORCEMENT ACT OF 1989. On
August 9, 1989, President Bush signed into law the Financial Institutions
Reform, Recovery and Enforcement Act of 1989 ("FIRREA"). FIRREA contains
provisions, which among other things: (1) establish two separate financial
industry insurance funds, both administered by the FDIC - the Bank Insurance
Fund and the Savings Association Fund; (2) abolish the Federal Home Loan Bank
Board and establish the Office of Thrift Supervision as an office of the
Treasury Department, with responsibility for examination and supervision of all
savings and loan associations; (3) increase the insurance premiums paid by
FDIC-insured institutions; (4) permit bank holding companies to acquire healthy
savings and loan associations; (5) enhance federal banking agencies' enforcement
authority over the operations of all insured depository institutions and


                                          8
<PAGE>

increase the civil and criminal penalties that may be imposed in connection with
violations of laws and regulations; (6) curtail investments and certain
activities of state-chartered savings and loan associations; and (7) increase
the capital requirements of savings and loan associations. Management of the
Company does not believe that the provisions of FIRREA have had or will have a
material adverse impact on the Company's consolidated financial position or
results of operations.

     COMPETITIVE EQUALITY BANKING ACT.  The Competitive Equality Banking Act of
1987 contained provisions which, among other things: (1) permanently closed the
loophole which formerly allowed for the creation of "non-bank banks"; (2)
limited the restrictions imposed on banks on the availability of funds deposited
by check; and (3) provided explicit leasing authority for national banks.  The
enactment of this legislation has not had a material adverse effect on the
Company's consolidated financial condition or results of operations.

     INTERSTATE BANKING.  In September 1986, California adopted an interstate
banking law.  The law allows California banks and bank holding companies to be
acquired by banking organizations in other states on a reciprocal basis (i.e.,
provided the other state's laws permit California banking organizations to
acquire banking organizations in that state on substantially the same terms and
conditions applicable to banking organizations solely within that state).  The
law took effect in two stages.  The first stage, which became effective July 1,
1987, allowed acquisitions on a reciprocal basis within a region consisting of
all 11 states (Alaska, Arizona, Colorado, Hawaii, Idaho, Nevada, New Mexico,
Oregon, Texas, Utah and Washington) which currently permit acquisitions by
California banking organizations of banks and bank holding companies in such
states.  The second stage, which became effective January 1, 1991, allows
interstate acquisitions on a national reciprocal basis.  The Company believes
that this legislation will further increase competition as out-of-state
financial institutions enter the California market.  Most recently U.S. Bancorp
purchased California Bancshares, Inc.; a community- based holding company with
approximately 21 independent banks in the surrounding area in which the Bank
operates.  U. S. Bancorp was subsequently purchased by First Bank headquartered
in Minneapolis.  It is anticipated that such a purchase may in fact be
beneficial to the Bank as it may open opportunities to prospects that enjoy
dealing with a community bank.  If there is a negative effect on the Bank it
might be that this merger might increase the resources available to the 21
independent banks being purchased.

     CAPITAL ADEQUACY GUIDELINES.  The FRB has issued capital adequacy
guidelines establishing a risk-based capital framework consisting of a
definition of capital comprised of a core component (essentially shareholders'
equity less goodwill) ("Tier 1 capital"), a supplementary component ("Tier 2
capital"), a system for assigning assets & off-balance sheet items to four
weighted risk categories (with higher levels of capital being required for the
categories being perceived as representing greater credit risk) and a schedule
for achieving a minimum risk-based capital ratio of 7.25% by the end of 1990
(which at least 3.625% should be in the form of common shareholders' equity) and
8% by the end of 1992 (which at least 4% should be in the form of common
shareholders' equity).  An institution's risk-based capital would be determined
by dividing its qualifying capital by its risk -weighted assets.

     The guidelines make regulatory capital requirements more sensitive to the
differences in risk profiles among banking institutions, take off- balance sheet

account when assessing capital adequacy and minimize disincentives to holding
liquid low-risk assets.  In addition, the guidelines may require some banking
institutions to increase the level of their common shareholders' equity.  It is
not anticipated that the guidelines will have a material adverse effect on the
Company's financial condition or results of operations over the short term.  At
the end of 1998, the guidelines provided for a minimum risk-based capital ratio
of 8%, and this provision may limit the Company's ability to increase its assets
or require the Company to raise additional equity to facilitate growth.

     On August 2, 1990, the FRB adopted standards for compliance by banking
organizations with risk-based capital guidelines to include a minimum leverage
ratio of 4% of Tier 1 capital to total average assets (the "leverage ratio")
based upon the definition of Tier 1 capital for 1998.  The FRB emphasized that
the leverage ratio constitutes a minimum requirement for well-run banking
organizations having diversified risk, including no undue interest rate risk
exposure, excellent asset quality, high liquidity, good earnings and a favorable
composite rating under the applicable regulatory rating system.  Banking
organizations experiencing or anticipating significant growth, as well as those
organizations which do not exhibit the characteristics of a strong well-run
banking organization described above, will be required to maintain minimum
capital ranging from 100 to 200 basis points in excess of the leverage ratio.

     The FRB leverage ratio establishes a new limit on the ability of banking
organizations to increase assets and liabilities without increasing capital
proportionately.  In management's opinion, the leverage ratio will have no
material effect on its capital needs in the foreseeable future.  The Bank's
leverage ratio at December 31, 1998 was 8.0% (See "Summit Bancshares, Inc. 1998
Annual Report - Footnote #8). 

EMPLOYEES

     As of December 31, 1998, the Bank employed 43 full time employees and 3
part time employees for a total equivalent of 44.7 full time employees.   At the
present time there are no salaried employees of the Company.

COMMITMENTS AND LINES OF CREDIT

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers. 
These financial instruments include commitments to extend credit, and standby
letters of credit.  These instruments involve, to varying degrees, elements of
credit risk in excess of the amount recognized in the statement of financial
position.  The contract amount of those instruments reflects the extent of
involvement the Company has in particular classes of financial instruments.

The Company's 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 notional amount of
those instruments.  The Company uses the same credit policies in making
commitments and conditional obligations as it does for on-balance-sheet
instruments.  At December 31, 1998, financial instruments whose contract amounts
represent credit risk:

</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.  Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee.  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 Company evaluates each customer's
credit worthiness on a case-by-case basis.  The amount of collateral obtained if
deemed necessary by the Company upon extension of credit is based on
management's credit evaluation of the counter-party.  Collateral held varies but
may include accounts receivable, inventory, property, plant, and equipment, and
income-producing commercial properties.  Standby letters of credit are
conditional commitments issued by the Company to guarantee the performance of a
customer to a third party.  Most all guarantees expire within one year.  The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan facilities to customers.

Approximately 8.4% of the Company's loans are concentrated with health care
professionals.

     The subsidiary Bank's policy is to recognize interest income on an accrual
basis unless the full collectibility of principal and interest is uncertain. 
Loans that are delinquent 90 days as to principal or interest are placed on a
non-accrual basis, unless they are well secured and in the process of
collection, and any interest earned but uncollected is reversed from income. 
Collectibility is determined by considering the borrower's financial condition,
cash flow, quality of management, the existence of collateral or guarantees and
the state of the local economy.

     The total OREO amount, $212 ,000, is related to two properties. One of the
properties is vacant land in the Oakland Hills.  The second property is three
lots located in Pacheco.

     The allowance for loan losses is maintained at a level considered adequate
to provide for losses that can be reasonably anticipated.  The reserve is
increased by provisions and reduced by net charge-offs.  The Bank makes credit
reviews of the loan portfolio, considers current economic conditions, loan loss
experience, and other factors in determining the adequacy of the reserve
balance.  The allowance for loan losses is based on estimates and ultimate
losses may vary from current estimates.  As adjustments become necessary, they
are reported in earnings in the periods in which they become known.

     Any loans classified for regulatory purposes as loss, doubtful,
substandard, or special mention that have not been disclosed under Item III of
Industry Guide 3 do not (i) represent or result from trends or uncertainties
which management reasonably expects will materially impact future operating
results, liquidity or capital resources, or (ii) 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 program.

     (c) DIVIDENDS.  On June 10, 1998 the Company paid a 75-cent per share cash
dividend in addition to a similar 75 cent per share dividend on December 3,

dividends so long as said dividends do not inhibit future development. 
Additionally, payment of cash dividends by the Company is dependent upon payment
of dividends by the Bank to the Company.  Payment of cash dividends by the Bank
may under certain circumstances require approval of the California
Superintendent of Banks, and as a matter of law, the Bank may only declare cash
dividends from the lesser of its retained earnings or its undistributed net
income from the last three years.  Less any dividends paid during those three
years.  In the event that the Bank does not have retained earnings or net income
for the last three fiscal years, the Bank may declare dividends only with the
prior written consent of the Superintendent.

                           OFFICE SERVICE AGREEMENT

This Agreement is dated October 8, 1997 and is entered into in Pleasanton, CA 
by and between Rostex, Inc., dba HQ Business Centers (hereinafter "HQ") and 
Summit Bank (hereinafter "Client").

HQ and Client agree that HQ shall grant to Client for and in consideration of 
the agreements and fee(s) set forth herein, a license to use the Office(s) as 
from time to time designated by HQ and, in common with HQ's other clients, a 
license to use HQ's Business Center facilities and services, in accordance 
with the terms hereof.

1.   BASIC TERMS.  This Section 1 contains the basic terms of this Agreement 
and all provisions of this Agreement are to be read in accord therewith:

     A.  Base Services: HQ's Complete Executive Office Program, including the 
     use of executive offices complete with professional administrative 
     staff, telephone answering and such other inclusive services as defined 
     in Schedule "A".

     B.  Additional Services: Access to additional business services for 
     purchase as needed by Client, including secretarial, administrative, 
     telecommunications support and such other services are as defined in 
     Schedule "B".

     C.  HQ Business Center  Pleasanton

     D.  Building  5820 Stoneridge Mall Road, Pleasanton, CA 94588

     E.  Office [(number(s)]  23 having a maximum occupancy of 2 person(s).

     F.  Commencement Date  December 1, 1997

     G.  Initial Term  12 Months

     H.  End of Initial Term  November 30, 1998

     I.  Monthly Base Services Fee  $1669.00

     J.  Refundable Services Retainer  $2503.50

2.   OFFICE.  Client shall, as part of the Base Services, be granted a 
license to use the Office and shall have access to the Office twenty-four 
(24) hours a day, seven (7) days a week. HQ agrees to provide office 
cleaning, maintenance services, electric heating and air conditioning to the 
Office for normal office use in such reasonable quantities and during such 
reasonable hours as shall be determined by HQ or the Building. In addition, 
Client will have reasonable use of HQ common area facilities. Client shall 
use the Office and common areas of the HQ Business Center solely for general 
office use in the conduct of the Client's business.

     If, for any reason whatsoever, HQ is unable to provide use of the Office 
or a mutually agreed upon alternative Office at the time herein agreed, 
Client may either extend the Commencement time herein agreed, Client may 
either extend the Commencement Date until the Office becomes available or, as 
its sole remedy for such failure, cancel and terminate this Agreement if the 
use of the Office is not available to Client within five (5) business days 
after written notice to HQ by Client, in which case any prior payments shall 
be fully refunded. No such failure to provide use of the Office shall subject 
HQ to any liability for loss or damage, nor affect the validity of this 
Agreement or the obligations of the Client hereunder.

     HQ will have the right to relocate Client, AT HQ'S EXPENSE, to another 
office in the HQ Business Center, and to substitute such other office for the 
Office licensed hereby, provided such other office is substantially similar 
in area and configuration to Client's contracted office and provided Client 
shall incur no increase in the Monthly Base Services Fee.

3.   SERVICES. HQ agrees, in consideration of the Monthly Base Services Fee, 
to provide Base Services to Client as described in Schedule "A". From time to 
time during the Term, HQ may, at its option, make other services available to 
Client of the nature described in Schedule "B", at fees that are from time to 
time established by HQ. In the event Client is in default of this Agreement, 
HQ may, at its option, cease furnishing any and all services including 
telephone services.

     Client will not offer to any party in the HQ Business Center or the 
Building, any of the services that HQ provides to its clients including, but 
not limited to, the services described in Schedule "A" or "B".

     HQ will answer all incoming telephone calls, unless otherwise mutually 
agreed, during normal business hours, as determined by HQ. Answering service 
will be limited to normal business communications, excluding inbound 
telemarketing and advertising response which requires pre-approval by HQ and 
shall be subject to fees established from time to time by HQ.

     Client will use only telecommunications systems and services as provided 
by HQ. Client will pay to HQ a monthly equipment rental fee for the use of 
each telephone instrument and voice lines. In the event HQ discontinues the 
offering of long distance service, Client will provide its own long distance 
service through a locally accessed long distance carrier.

     Client acknowledges that due to the imperfect nature of verbal, written 
and electronic communications, neither HQ nor any of its officers, directors, 
employees, shareholders, partners, agents or representatives shall be 
responsible for damages, direct or consequential, that may result from the 
failure of HQ to furnish any service, including but not limited to the 
service of conveying messages, communications and other utility or services 
required under this Agreement or agreed to by HQ. Client's sole remedy and 
HQ's sole obligation for any failure to render any service, any error or 
omission, or any delay or interruption with respect thereto, is limited to an 
adjustment to Client's billing in an amount equal to the charge for such 
service for the period during which the failure, delay or interruption 
continues.

     CLIENT EXPRESSLY WAIVES, AND AGREES NOT TO MAKE ANY CLAIM FOR DAMAGES, 
DIRECT OR CONSEQUENTIAL, ARISING OUT OF ANY FAILURE TO FURNISH ANY UTILITY, 
SERVICE OR FACILITY, ANY ERROR 

                                  Page 1 of 6  -C- 1995 HQ NETWORD SYSTEMS INC.

OR OMISSION WITH RESPECT THERETO, OR ANY DELAY OR INTERRUPTION OF THE SAME.

4.   DURATION OF AGREEMENT.  Upon the End of Initial Term, or any extension 
thereof, the term of this Agreement and the license herein granted shall be 
automatically extended for the same period of time as the Initial Term, upon 
the same terms and conditions as contained herein, unless either party gives 
notice to the other in writing to the contrary at least sixty (60) days prior 
to the End of Initial Term (90 days if Client has licensed the use of three 
or more offices).

     Tenant hereby agrees to pay HQ, the total monthly rent for each full 
month, or part thereof, in which the tenant occupies the premises. Tenant is 
deemed to occupy the premises during the required notice period herein, 
whether or not tenant is physically in the premises. (Eg: 30 day notice 
presented on the 15th day of month 1 requires payment of total monthly rent 
for month 2).

     Upon any termination of this Agreement, whether by lapse of time or 
otherwise, or upon any revocation of Client's license herein granted, the 
Client shall cease all use of the Office, the HQ Business Center and all 
services immediately. For each and every month or portion thereof that Client 
continues use of the Office after the termination of this Agreement by lapse 
of time or otherwise, without the express written consent of HQ, Client shall 
pay HQ an amount equal to double the Monthly Base Services Fee computed on a 
per-month basis for each month or portion thereof that Client continues the 
use of the Office.

5.   PAYMENTS AND ESCALATIONS.  Client agrees to pay to HQ the Monthly Base 
Services Fee plus applicable sales or use taxes, in advance, on the first day 
of each calendar month during the Initial Term and all extensions thereof, 
without any deduction, offset, notice or demand. If the Commencement Date 
shall be other than the first day of a month or end of the last day of a 
month, fees for any such month shall be prorated. Charges for any Schedule 
"B" service purchased by Client from HQ shall be due and payable on the 10th 
of the month following the offer for any such service.

     One year after the Commencement Date of this Agreement and each and 
every anniversary date thereafter, the Monthly Base Service Fee will 
automatically increase by FOUR PERCENT (4%) of the Monthly Base Services Fee 
due for the month preceding such anniversary date.

     All Monthly Base Services Fees and other sums payable hereunder shall be 
payable at the office of HQ or at such other location or to any agent 
designated in writing by HQ. In addition to any other sums due, Client shall 
pay monthly late charges equal to five percent (5%) of all amounts that have 
not been paid to HQ within five (5) days of their respective due dates. The 
parties agree that such late charges are fair and reasonable compensation for 
costs incurred by HQ where there is default in any payment due under this 
Agreement.

     Upon the execution of this Agreement, Client shall pay HQ or its agent 
the Refundable Services Retainer. The Refundable Services Retainer need not 
be kept separate and apart from other funds of HQ, no interest shall be paid 
thereon, and may be used by HQ to provide Schedule "A" and "B" services under 
this Agreement. In addition to the Refundable Services Retainer, Client will, 
upon execution hereof, pay to HQ the Monthly  Base Services Fee for the first 
full month of the Initial Term.

     Client agrees that the Refundable Services Retainer shall not be used by 
Client as payment for the Monthly Base Services Fee for the last month of the 
Initial Term, or any extension thereof, in the event Client defaults in the 
performance of any of the terms hereof, HQ may terminate this Agreement and 
the license herein granted and may also use, apply or retain the whole, or 
any part, of the Refundable Services Retainer for the payment of any service 
fee or any other payment due hereunder, or for payment of any other sum that 
HQ may spend by reason of Client's default. If Client shall, at the end of 
the term of this Agreement, have fully and faithfully complied with all of 
the terms and provisions of this Agreement, and surrendered all keys, access 
cards and building passes, the Refundable Services Retainer, or any balance 
thereof, shall be returned to Client within forty-five (45) days thereafter.

6.   DAMAGES AND INSURANCE.  Client will not damage or deface the furnishings, 
walls, floors or ceilings, nor make holes for the hanging of pictures or make 
or suffer to be made any waste, obstruction or unlawful, improper or 
offensive use of the Office or the common area facilities. Client will not 
cause damage to any part of the Building or the property of HQ or disturb the 
quiet enjoyment of any other licensee or occupant of the Building. At the 
termination of this Agreement, the Office shall be in as good condition as 
when Client commenced the use thereof, normal wear and tear excepted. Client 
agrees to pay for repainting each Office used less than twelve (12) months by 
Client, at a cost not to exceed One Hundred Fifty Dollars ($150.00) per 
Office. HQ will have the right, at any time and from time to time, to enter 
the Office to inspect the same, to make such repairs and alterations as HQ 
reasonably deems necessary, and the cost of any such repair resulting from 
the act or omission of Client shall be reimbursed to HQ by Client upon 
demand. HQ shall have the right to show the Office to prospective Clients, 
provided HQ will use reasonable efforts not to disrupt Client's business.

     HQ and its respective directors, licensors, officers, agents, servants 
and employees shall not, to the extent permitted by law, except upon the 
affirmative showing of HQ's gross negligence or willful misconduct, be liable 
for, and Client waives all right of recovery against such entities and 
individuals for any damage or claim with respect to any injury to person or 
damage to, or loss or destruction of any property of Client, its employees, 
authorized persons and invitees due to any act, omission or occurrence in or 
about the HQ Business Center or the Building. Without limitation of any other 
provision hereof, each party hereto hereby agrees to indemnify, defend and 
hold harmless the other party hereto, and such other party's officers, 
directors, employees, shareholders, partners, agents and representatives from 
and against any liability to third parties arising out of, in the case of 
Client as an indemnifying party, Client's use and occupancy of the Office or 
any negligent act or omission of Client or Client's officers, directors, 
employees, shareholders, partners, agents, representatives, contractors, 
customers or invitees and, in the case of HQ as an indemnifying party, any 
act or omission constituting gross negligence or willful misconduct of HQ or 
HQ's officers, directors, employees, shareholders, partners, agents or 
representatives. Subject to the foregoing, Client assumes all risk of loss 
with respect to all personal property of Client, its agents employees, 
contractors, and invitees, within or about the HQ Business Center or the 
Building. Client acknowledges that it is the Client's responsibility to 
maintain insurance to cover the risks set forth in this paragraph.

     HQ and Client each hereby waive any and all rights of recovery against 
the other, or against the directors, licensors, officers, agents, servants 
and employees of the other, for loss of or damage to its property or the 
property of others under its control, to the extent such loss or damage is 
covered by any insurance policy.

     If the HQ Business Center is made unusable, in whole or in part, by fire 
or other casualty not due to negligence of Client, HQ may, at its option, 
terminate the Agreement upon notice to Client, effective upon such casualty, 
or may elect to repair, restore or rehabilitate, or cause to be repaired, 
restored or rehabilitated, the HQ Business Center, without expense to Client, 
within ninety (90) days or within such longer period of time as may be 
required because of events beyond HQ's control. The Monthly Base Services Fee 
shall be abated on a per diem basis for the portions of the Office that are 
unusable.

7.   DEFAULT.  Client shall be deemed to be in default under this Agreement: 
(a) if Client defaults in the payment of the Monthly Base Services Fee or 
other sums due hereunder or (b) if Client defaults in the prompt and full 
performance of any other provision of this Agreement and any such default 
continues in excess of five (5) business days after written notice by HQ.

     Should Client be in default hereunder, HQ shall have the option to 
pursue any one or more of the following remedies 

                                  Page 2 of 6  


<PAGE>

without any additional notice or demand whatsoever and without limitation to 
HQ in the exercise of any remedy.

     (1)  HQ may, if HQ so elects, without any additional notice of such 
election or demand to Client, either forthwith terminate this Agreement and 
the license to use any portion of the HQ Business Center, and may enter into 
the Office and take and hold possession of the contents thereof, without 
releasing Client, in whole or in part, from the Client's obligations 
hereunder. In the event of such termination, HQ may, at its option, declare 
the entire amount of the Monthly Base Services Fee which would become due 
and payable during the remainder of the term, to be due and payable 
immediately, in which event, Client agrees to pay the same at once.

     (2)  Pursue any other remedy now or hereafter available to HQ. HQ's 
exercise of any right or remedy shall not prevent it from exercising any 
other right or remedy.

     Client agrees to pay all costs and expenses, including reasonable 
attorneys' fees, expended or incurred by HQ in connection with the 
enforcement of this Agreement, the collection of any sums due hereunder, any 
action for declaratory relief in any way related to this Agreement, or the 
protection or preservation of any rights of HQ hereunder.

directly or as an independent contractor, any person who is at that time, or 
was during the term of this Agreement, an employee of HQ. In the event of a 
breach of any obligation of Client contained in this paragraph. Client shall 
be liable to HQ for, and shall pay to HQ, on demand, liquidated damages in 
the sum of $10,000.00 for each employee with respect to whom such breach 
shall occur, it being mutually agreed that the actual damage that would be 
sustained by HQ as the result of any such breach would be, from the nature of 
the case, extremely difficult to fix and that the aforesaid liquidated damage 
amount is fair and reasonable.

     9. MISCELLANEOUS.

     A. This is the only Agreement between the parties. No other agreements 
are effective. All amendments to this Agreement shall be in writing and 
signed by all parties. Any other attempted amendment shall be void. The

remainder hereof.

     B. All waivers must be in writing and signed by the waiving party. HQ's 
failure to enforce any provision of this Agreement or its acceptance of fees 
shall not be a waiver and shall not prevent HQ from enforcing any provision

waive any default of Client or to extend, reinstate or continue the term 
hereof.

such permitted assignment, Client shall not thereby be relieved of any of its 
obligations under this Agreement.

     G. The Rules and Regulations of the Building and of HQ as defined on 
Schedule "C" hereto and any additional schedules that may be attached hereto 
are expressly made a part of this Agreement and Client expressly covenants

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 
OF OPERATIONS 

The matters addressed in this Annual Report, with the exception of the 
historical information presented, may incorporate certain forward-looking 
statements involving risks and uncertainties, including the risks 
discussed under the heading "Certain Factors That May Affect Future 
Results" and elsewhere in this Report.

This section is a review of Summit Bancshares, Inc.'s (the Company) 
results as reflected in the Consolidated Financial Statements.  It 
discusses the principal items of income and expense and the factors 
affecting the Company's financial position.  This discussion should be 
read together with the Selected Financial Data and Consolidated Financial 
Statements included elsewhere in the Annual Report. 

The Company's wholly owned subsidiary, Summit Bank (the "Bank"), has 
conducted the business of a commercial bank since 1982. It provides 
commercial credit and various checking and savings account products for 
small and mid-sized businesses and for professionals as well as 
individual consumers.


SUMMARY OF EARNINGS 

The Company's net income for 1998 was $1,767,392  compared to $1,708,000 
in 1997, and $1,412,000 in 1996. The increase in 1998 net income over 
1997 is attributed to an increase in investment income.  The increase in 
1997 net income from 1996 is attributed to an increase in higher yielding 
assets brought about by an increase in loans and improved interest 
margins. The net income of $1,767,000  for 1998 represents $3.81 per share 
earnings, compared to $3.72 per share in 1997 and $3.11 per share in 
1996.



<PAGE>


NET INTEREST INCOME 

The primary source of income for the Company is Net Interest Income or 
"Gross Margin" which is the difference between interest earned on loans 
and investments and interest paid on deposits and other liabilities.  In 
general, net interest income is affected by a change in interest rates.  
As interest rates rise or fall, so will the Company's net interest 
income, excluding changes in total assets.  The primary reasons for this 
is that the Company's investment portfolio earns income on a fixed 
interest rate basis while a majority of the lending portfolio earns 
income on a floating interest rate basis.  In addition, all investments 
are held to maturity and 45% of the investment portfolio matures in one 
year.  Regarding loans, approximately 61% of the loans outstanding mature 
within one year, while the longest maturity is twenty-five years.  In a 
declining interest rate environment interest income on loans will 
generally decline faster than the investment income and vice versa.  To 
offset any decline in interest income due to a declining interest rate 
environment, the Company monitors closely its interest expense on 
deposits.  Of the total time certificates of deposit outstanding at year 
end, all but 1% mature within one year while 73% mature within 90 days.  
Thus the Company is able to minimize the effects of a declining interest 
rate environment by repricing these instruments on a more frequent basis 
than if the average maturity were longer than 1 year.  

Net interest income for 1998 was $6,458,000, which is slightly higher 
than the $6,457,000 posted in 1997 and as compared to $5,439,000 in 1996.  

The performance in 1998 was primarily the result of an decrease in the 
average prime rate, which decreased from 8.44% in 1997 to 8.37% in 1998.  
Average earning assets increased 16.9% from $86,830,000 in 1997 to 
$101,531,000 in 1998; average total deposits also increased 17.0% from 
$83,091,000 in 1997 to $97,288,000 in 1998, and as compared to 
$74,752,000 in 1996.  $8,476,000 of the 1998 increase was centered in 
interest bearing accounts.


<PAGE>



The increase in 1997 was primarily the result of an increase in the 
average prime rate, which increased from 8.25% in 1996 to 8.44% in 1997.  
Average earning assets increased 11.2% from $78,107,000 in 1996 to 
$86,830,000 in 1997; average total deposits also increased 11.2% from 
$74,752,000 in 1996 to $83,091,000 in 1997, and as compared to 
$68,492,000 in 1995.  $4,475,000 of the 1997 increase was centered in 
interest bearing accounts.

Average loans outstanding decreased by 4.5% in 1998 to $55,299,000 as 
compared to $57,906,000 in 1997 and $48,355,000 in 1996.  Average 
outstanding investments increased 59.8% to $46,232,000 in 1998 as 
compared to $28,924,000 in 1997 and $29,989,000 in 1996.   The average 
loan to deposit ratio decreased in 1998 to 56.8% as compared to 69.7% in 
1997 and 65.2% in 1996.  The yield on average earning assets was 8.6% in 
1998 as compared to 9.7% in 1997 and 9.3% in 1996.

Interest expense increased 16.9% to $2,267,000 in 1998 from $1,940,000 in 
1997 and $1,938,000 in 1996.  Average interest-bearing deposits increased 
14.7% in 1998 to $65,987,000 as compared to $57,512,000 in 1997 and 
$52,715,000 in 1996 and were primarily centered in the time certificates 
of deposit.  Average non-interest bearing deposits increased 23.3% in 
1998 to $31,300,000 as compared to $25,579,000 in 1997 and $22,037,000 in 
1996.  Overall cost of funds in 1998 was 2.3% as compared to 2.6% in 1997 
and 2.5% in 1996.

NON-INTEREST INCOME AND EXPENSE

Non-interest income, consisting primarily of service charges on deposit 
accounts, and other customer fees and charges including rents, was 
$596,000 in 1998, a increase from $516,000 in 1997, and a increase from 
$539,000 in 1996.  Total service charge income from deposit accounts 
increased by 14.4% from $304,000 in 1997 to $348,000 in 1998, while total 
income from other charges increased 7.4% from $211,000 in 1997 to 
$247,000 in 1998. 

The deposit income increase in 1998 was the result of increases in 
service charges related to return check charges.



<PAGE>


The increase in other income charges in 1998 was related to the sale of 
other real estate owned.

The deposit income decrease in 1997 resulted primarily from a decrease in 
service charges related to analysis, which were $12,000 less than 1996 
receipts.  The decrease in other income charges in 1997 was related to a 
$14,000 decrease in wire transfer fees.

Non-interest expenses increased 4.5% to $3,908,000 in 1998, from 
$3,738,000 in 1997 and $3,408,000 in 1996. Salary expense increased 6.5% 
from $2,111,000 in 1997 to $2,249,000 in 1998, and was due to normal 
staffing needs and the first full year of operations of our Pleasanton 
office.  In addition, business development and entertainment expense 
decreased from $111,000 in 1997 to $102,000 in 1998.  Foreclosures and 
OREO expense decreased from $129,000 to $19,000, primarily due to the 
sale of the largest other real estate owned properties.  In addition, 
consulting fees decreased from $84,000 in 1997 to $49,000 in 1998.  
postage expense also decreased from $56,000 in 1997 to $42,000 in 1998.

Non-interest expenses increased 9.6% to $3,738,000 in 1997, from 
$3,408,000 in 1996 and $3,355,000 in 1995. Salary expense increased 12.4% 
from $1,878,000 in 1996 to $2,111,000 in 1997, and was due to normal 
staffing needs and an increase in profit sharing and 401(k) 
contributions.  In addition, business development and entertainment 
expense increased from $78,000 in 1996 to $111,000 in 1997, which was due 
to an aggressive sales program.  Foreclosures and OREO expense increased 
from $85,000 to $129,000, primarily due to a write down of $75,000 on one 
of the Bank's properties.  Marketing expense increased from $8,000 in 
1996 to $46,000 in 1997, primarily due to changes in the Bank's marketing 
brochures.  This was also a primary factor in the increase in postage 
expense from $37,000 in 1996 to $56,000 in 1997.  Offsetting these 
increases were decreases in audit and accounting expenses, which went 
from $46,000 in 1996 to $39,000 in 1997.  In addition, consulting fees 
decreased from $99,000 in 1996 to $84,000 in 1997.  Legal expenses also 
decreased from $127,000 in 1996 to $41,000 in 1997.

The Bank's allowance for loan losses as a percent of loans was 2.5% and 
2.0% as of December 31, 1998 and 1997, respectively.  The average in the 
industry for banks our size is approximately 1.77%.  Total gross loans 
charged off in 1998, was $51,000 compared to $105,000 in 1997 and $83,000 
in 1996.

PROVISION FOR INCOME TAXES

The provision for income taxes reflects a combined Federal and California 
effective tax rate of 42% in 1998, compared to 42.4% in 1997 and 41.2% in 
1996, as described in Note 6 to the Financial Statements.

LIQUIDITY AND CAPITAL 

Liquidity is defined as the ability to meet present and future 
obligations either through the sale or maturity of existing assets or by 
the acquisition of funds through liability management.  Additionally, the 
Bank's investment portfolio is managed to provide liquidity as well as 
appropriate rates of return.  It is the Company's practice to hold 
securities until maturity rather than actively trade its portfolio.  As 
of December 31, 1998 the Company had 26,000,000 in cash and cash 
equivalents compared to $21,574,000 as of December 31, 1997, and 
$21,169,000 as of December 31, 1996.  The ratio of net loans to deposits 
as of December 31, 1998 was 48.2% compared to 67.3% as of December 31, 
1997, and 63.9% as of December 31, 1996.

The Bank maintains a portion of its assets in loans, time deposits with 
other financial institutions and investments with short-term maturities.  
More specifically, loans, time deposits with other financial institutions 
and investments due within one year totaled $67,643,000 at December 31, 
1998, $46,590,000 at December 31, 1997, as compared to $56,323,000 at 
December 31, 1996.  This is equivalent to 54.3%, 44.6% and 60.6% of total 
assets at the corresponding year-ends, respectively. During 1998, the 
Company repurchased 1,150 shares of its common stock for a total price of 
$55,370. The Company plans to continue its repurchase program as an 
additional avenue for liquidity for its shareholders as long as it is 



<PAGE>



economically appropriate to do so.  The program has not affected the 
Company's liquidity or capital positions or its ability to operate.  In 
addition, the Company's subsidiary Bank remains more than well-
capitalized under current regulatory requirements.

CREDIT CONCENTRATION

A part of the subsidiary Bank's marketing strategy is to offer quality 
financial services to the professional and small business communities. 
The Company has been especially successful in targeting health care 
professionals.  This segment has traditionally provided high levels of 
deposits and low loan losses.  While approximately 8.4% of the Company's 
loans are concentrated with health care professionals, the Bank has had 
only two charge-offs related to this business segment totaling $133,206 
since it was founded in 1982.  Health care reform has received close 
scrutiny over the past few years as the Clinton administration continues 
to attempt to restructure the method by which health care is provided to 
the public.  To date it appears that such reform is not likely to occur 
in the immediate future.  However, over the past few years, the doctors 
and health care providers in the Company's communities have been 
adjusting to the emerging trends in this industry. This includes higher 
percentages of patients on Medicare, closer scrutiny from insurance 
carriers, and movement to managed care and "capitation" contracts.  
Through this process, the Company has not experienced any noticeable 
deterioration in credit quality.  The Company cannot predict the ultimate 
outcome of health care reform.  However, the Company closely  monitors 
the status of reform and considers the potential impact of any reform on 
its current customers and its underwriting of loans to healthcare 
professionals.

NON-PERFORMING ASSETS

The decrease in non-performing assets from December 31, 1997, to December 
31, 1998 is due primarily to the sale of a large other real estate owned 
property.  The increase in loans 90 days or more past due and still 
accruing and non-accrual loans are being monitored appropriately.  At 
December 31, 1998, four loans were on non-accrual status.

IMPACT OF YEAR 2000

Many computer systems and software products now in use around the world 
experience problems handling dates beyond the year 1999 and will need to 
be modified before the year 2000 in order to remain functional.  As a 
result, before the year 2000, computer systems and/or software products 
and applications used by many companies may need to be upgraded to comply 
with such year 2000 requirements.

The Company is currently expending resources to review its internal 
systems, products and the readiness of third parties with whom it has 
business relationships and has assigned a dedicated task force to develop 
and implement a year 2000 plan (the "Plan") which is designed to cover 
all of the Company's activities.  The Plan, which has executive 
sponsorship, is reviewed regularly by senior management and the Board of 
Directors and includes the evaluations of both information technology 
("IT") and non-IT systems, consists of five steps.

Step one involved increasing awareness by educating and involving the 
Board of Directors and all levels of management, and all employees 
regarding the need to address year 2000 issues.  Step two consisted of 
identifying all of the Company's systems, products and relationships that 
may be impacted by year 2000.  Step three involved determining the 
Company's current state of year 2000 readiness for those areas identified 
in step two and prioritizing areas that need to be fixed.  Step four 
consisted of developing a plan for those areas identified as needing 


<PAGE>


correction.  Step five consists of the implementation and execution of 
the Company's Plan and completing the steps identified to attain year 
2000 readiness.  The company is currently executing step five.  The 
Company has upgraded all of its IT and non-IT systems and has tested the 
majority of these systems.  Based on the Company's assessment to date, it 
believes that all of the Company's internal IT and non-IT systems that 
have been tested are year 2000 compliant.

The Company believes that any modifications deemed necessary will be made 
on a timely basis and does not believe that the cost of such 
modifications will have a material effect on the Company's operating 
results.  To date, the Company's costs related to the year 2000 issues 
have amounted to approximately $85,000 and the Company does not expect 
the aggregate amount spent on the year 2000 to exceed $125,000.  The 
Company is currently preparing a contingency plan with respect to year 
2000 requirements.

The Company's expectations as to the extent and timeliness of 
modifications required in order to achieve year 2000 compliance is a 
forward-looking statement subject to risks and uncertainties.  Actual 
results may vary materially as a result of a number of factors, 
including, among others, those described above in this section.  There 
can be no assurance that unexpected delays or problems, including the 
failure to ensure year 2000 compliance by systems or products supplied to 
the Company by third parties, will not have an adverse effect on the 
Company, its financial performance and results of operations.  In 
addition, the Company cannot predict the effects of the year 2000 issue 


<PAGE>



on its customers or the resulting effects on the Company.  As a result, 
if such customers do not take preventative and/or corrective actions in a 
timely manner, the year 2000 issue could have an adverse effect on their 
operations and accordingly have a material adverse effect on the 
Company's business, financial condition and results of operations.  
Furthermore, the Company's current understanding of expected costs is 
subject to change as the project progresses and does not include the cost 
of internal software and hardware replaced in the normal course of 
business whose installation otherwise may be accelerated to provide 
solutions to the year 2000 compliance issues.


CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

The primary factor which may affect future results is the fluctuation of 
interest rates in the market place more commonly referred to as interest 
rate risk.  Interest rate risk is the exposure of a bank's current and 
future earnings and equity capital arising from adverse movements in 
interest rates.  It results from the possibility that changes in interest 
rates may have an adverse effect on a bank's earnings and its underlying 
economic value.  Changes in interest rates affect a bank's earnings by 
changing its net interest income and the level of other interest-
sensitive income and operating expenses.  As mentioned previously, the 
potential decrease in a declining interest rate environment would be 
minimized by an increase in assets. In addition, earnings and growth of 
the company are and will be affected by general economic conditions, both 
domestic and international, and by monetary and fiscal policies of the 
United States Government, particularly the Federal Reserve Bank.

earnings of the Company and management's assessment of the future needs 
for funds.
