ITEM 1.  BUSINESS

GENERAL

    Coast Bancorp is a commercial bank holding company incorporated in the State
of California in 1995. The holding company was formed to acquire Coast
Commercial Bank located in Santa Cruz, California. Coast Commercial Bank
incorporated as a California state banking corporation on April 27, 1981, and
commenced operations on February 17, 1982. We became the holding company for the
Bank on July 25, 1995.

    On January 20, 1999 our board of directors approved a 2-for-1 stock split
effective for shareholders of record on February 5, 1999. Accordingly, all
historical financial information has been restated as if the stock split had
been in effect for all periods presented.

GENERAL BANKING SERVICES

    We engage in a broad range of financial services activities in our primary
market of Santa Cruz County, and also serve the adjacent areas of San Benito,
Santa Clara and Monterey counties. The City of Santa Cruz, situated 80 miles
south of San Francisco and 35 miles southwest of San Jose, is the largest city
in Santa Cruz County.

    We emphasize the needs of local business people and serve individuals,
retailers, professionals and small and medium-sized businesses and operate
through our corporate offices located in Santa Cruz, California and through our
branch offices located in Santa Cruz, Aptos, Capitola, Scotts Valley and
Watsonville, California. Services offered include a full range of commercial
banking services, including the acceptance of demand, savings and time deposits,
overdraft protection for checking accounts, and the making of commercial, real
estate (including residential mortgage), personal, home improvement, automobile
and other installment and term loans. We are one of the largest Small Businesses
Administration ("SBA") lenders in California and have been granted status as a
"preferred lender," allowing us to make SBA loans without first having the SBA
approve the loan, and are also a seller/servicer of Freddie Mac mortgage loans.
We also offer travelers' checks, safe deposit boxes, notary public services,
Visa credit cards, courier service for pick-up of non-cash deposits, debit cards
usable at many ATM's and retailers nationwide and a 24 hour telephone service
for deposit and loan account information. We operate automated teller machines
at our branches and at Seascape Village in Aptos, California. Our Investment
Services Department provides financial planning services, financial consulting,
asset management and the purchase and sale of stocks and bonds through a third
party provider.

    The total population base in Santa Cruz County is approximately 249,000
people. Santa Cruz County's economic base has several significant components
including education (e.g., the University of California at Santa Cruz); disk
drive and software companies headquartered in the northern part of the county
due to its proximity to the high tech base of Silicon Valley in adjacent Santa
Clara County; tourism because of the beaches and Santa Cruz Boardwalk; and
agriculture in the southern part of the county in and around Watsonville.

    On December 14, 1999 Coast Bancorp and Greater Bay Bancorp, the parent of
Cupertino National Bank, Mid-Peninsula Bank, Peninsula Bank of Commerce, Golden
Gate Bank, Bay Area Bank, Bay Bank of Commerce and Mt. Diablo National Bank,
signed a definitive agreement for a merger of the two companies. The agreement
provides for Coast Bancorp's shareholders to receive shares of Greater Bay
Bancorp stock, based on the average price of Greater Bay's stock during a 20
trading day period preceding the effective date of the merger, in a tax-free
exchange to be accounted for as a pooling of interests. Assuming the price of
Greater Bay's stock as of December 31, 1999 equaled the average price of Greater
Bay's stock during a 20 trading day period preceding the effective date of the
merger, Coast Bancorp's shareholders would receive approximately 3,072,000
shares of Greater Bay Bancorp stock. Following the

                                       3
<PAGE>
transaction, Coast Bancorp's shareholders will own approximately 18.4% of the
combined company's stock. The transaction is expected to be completed in the
second quarter of 2000 subject to approval of the transaction by Coast Bancorp's
and Greater Bay's shareholders and receipt of regulatory approvals. As of
December 31, 1999, based on Greater Bay's supplemental consolidated financial
statements, Greater Bay Bancorp had $2.846 billion in assets, $2.506 billion in
deposits and $173.6 million in shareholders' equity. The combined company, on a
pro-forma basis after giving effect to the merger, would have had total assets
of approximately $3.216 billion and shareholders' equity of over $206 million at
December 31, 1999.

    Management believes that the merger offers significant opportunities to
enhance the spectrum of financial services offered to both existing and future
customers of Coast Bancorp.

    We currently have no applications pending to open additional branch offices,
but we may increase the number of our banking facilities in the Bank's trade
areas when expansion is appropriate. Banking facilities that may be considered
in any future expansion include traditional branch offices and mini-branch
offices as in-fill strategies and loan production offices in neighboring
counties. No such facilities are currently under development. Expansion is, of
course, dependent on obtaining the necessary governmental approvals, a continued
earnings pattern and absence of adverse effects from economic conditions,
governmental monetary policies or competition. No assurance can be given that
expansion of our banking operations can be accomplished without being required
to raise additional capital in the future.

    Coast Commercial Bank is a member of the Federal Deposit Insurance
Corporation ("FDIC") and each depositor's account is insured up to $100,000. We
do not directly offer trust services or international banking services and do
not plan to do so in the near future.

COMPETITION

    Our service area consists of Santa Cruz County and extends into the adjacent
areas of San Benito, Santa Clara and Monterey counties. It is estimated that
Santa Cruz County contains 32 competitive banking offices, of which 3 offices
are owned by other independent banks. However, the Bank is the only independent
bank headquartered in Santa Cruz County. It is estimated that the primary
service area also contains 15 offices of savings and loan associations, and 7
offices of credit unions. Based upon total bank deposits as of June 30, 1999
(the last period for which data is available), we are fifth in market share in
Santa Cruz County.

    The banking business in California generally, and in our primary service
area specifically, is highly competitive with respect to both loans and
deposits, and is dominated by a relatively small number of major banks with many
offices operating over a wide geographic area. Among the advantages such major
banks have over us are their ability to finance wide ranging advertising
campaigns and to allocate their investment assets to regions of highest yield
and demand. These institutions offer certain services such as trust services and
international banking which we do not directly offer (but are offered indirectly
through correspondent institutions), and, by virtue of their greater total
capitalization (legal lending limits to an individual customer are limited to a
percentage of a bank's total capital), they have substantially higher lending
limits than our lending limit. Other entities, both governmental and in private
industry, seeking to raise capital through the issuance and sale of debt or
equity securities also provide competition for us in the acquisition of
deposits. We also compete with money-market funds for deposits.

    In order to compete with major financial institutions and other competitors
in our service areas, we build and retain our customer base by drawing upon the
experience of our executive and senior officers in serving business individuals,
and upon our specialized services, local promotional activities and the personal
contacts made by our officers, directors and employees. Our officers and
employees are strongly encouraged to participate in local civic and charitable
organizations and events, which has also served to promote our business. For
customers whose loan demand exceeds our legal lending limit, we may arrange for
large loans on a participation basis with correspondent banks. Our lending limit
is 15% of our capital

                                       4
<PAGE>
and allowance for credit losses for unsecured loans and 25% of our capital and
allowance for credit losses for unsecured and secured loans combined.

DEPOSITS

    Most of our deposits are attracted from individuals, small and medium-sized
businesses and professionals. No single customer relationship accounts for a
significant portion of our deposits.

LENDING ACTIVITIES

    We engage in a full complement of lending activities, including commercial,
real estate, SBA and consumer/installment loans.

    According to reports from the SBA for the federal fiscal year ended
September 30, 1999, we are one of the largest lenders in Northern California in
the SBA loan program. We make SBA loans from $20,000 to $1,500,000. SBA 7(a)
loans are for working capital, inventory and other purposes, and are government-
guaranteed up to 80% of the loan amount. We also make SBA loans for the purchase
or construction of owner occupied real estate which are also guaranteed up to
80%. The SBA loan program is subject to political and budgetary uncertainty
which in recent years has resulted in changes in the guaranteed portion and
maximum loan amounts of SBA loans.

    We also make commercial real estate loans for other purposes such as the
purchase or refinance of offices, warehouses, professional and industrial
buildings. A portion of these loans are SBA loans which are guaranteed by the
U.S. government in an amount up to 90% of the loan. Commercial real estate loans
generally are fully amortized over 15 years or have a 10 year term with a
twenty-five year amortization, and typically have a maximum loan to value ratio
of 70%. SBA loans for this purpose have a term of up to 25 years and a maximum
loan to value ratio of 90%. The Bank had outstanding real estate term loans of
$130,438,000 or 62% of our loan portfolio at December 31, 1999.

    We make commercial loans to small-to-medium sized businesses for working
capital, lines of credit, loans secured by inventory and receivables, and term
loans for equipment and for working capital. Typically, we obtain a security
interest in the collateral being financed or in other available assets of the
customer. Loan to value ratios vary but generally do not exceed 80%. As of
December 31, 1999, we had $35,023,000 in loans for these purposes representing
16% of our loan portfolio.

    We make real estate construction loans for the construction of single and
multi-family residential units, commercial and industrial properties, and SBA
approved owner occupied commercial real estate. These loans typically have
pre-qualified take outs for permanent financing or stand-by commitments and a
maximum loan to value ratio of 70%. We also make loans for lot or land
development with a maximum loan to value ratio of 60%. Construction loans are
secured by first deeds of trust. As of December 31, 1999, we had outstanding
real estate construction loans of $42,023,000 representing 20% of our loan
portfolio.

    Consumer and installment loans are made for household, family and other
personal expenditures on both a secured and unsecured basis. As of December 31,
1999 we had a total of $4,592,000 in consumer and installment loans representing
2% of our loan portfolio.

    We make residential mortgage loans which are typically 30 year loans with
either adjustable or fixed interest rates. These loans are sold to Freddie Mac
on a "servicing retained" basis, i.e., we continue to be paid a fee for
collecting payments on the loan and performing other services, or to other
investors on a "servicing released" basis, i.e. we have no further involvement
in the loan.

    We sell the guaranteed portion of SBA loans which we originate into the
secondary market as a source of liquidity and earnings. Additionally, we sell
residential mortgage loans we originate into the secondary market in order to
divest ourselves of the interest rate risk associated with these mostly fixed
interest rate products. No recourse is available to buyers of these loans after
90 days from the sale. Total loans serviced

                                       5
<PAGE>
for other investors were $118,464,000 as of December 31, 1999. For the years
ended December 31, 1999, 1998 and 1997, we sold loans totaling $74,420,000,
$82,869,000, and $48,255,000, respectively.

    Effective January 1, 1997, the Company adopted SFAS No. 125, "Accounting for
Transfer and Servicing of Financial Assets and Extinguishments of Liabilities".
SFAS No. 125 requires that an asset seller must meet defined conditions to
demonstrate that it has surrendered control over the assets. The failure to meet
these conditions usually results in on-balance-sheet treatment for the assets
and a liability for the sale proceeds received. SFAS No. 125 also requires that
contracts to service are recorded as an asset or a liability based on fair value
or on an allocation of the carrying amount of the financial asset. SFAS 125
covers subsequent accounting, including impairments, and eliminates the
distinction between excess and normal servicing.

    Credit risk relates to the ability of a borrower to repay the principal and
interest on its loan and is managed by adherence to credit standards and the
taking of collateral to secure most of our loans. These risks are generally
inherent in commercial lending. Certain risks are specific to particular types
of lending in which we engage such as real estate lending. The major risk
inherent in real estate lending is the potential decline in the value of the
property for market reasons or due to the condition of the property.

OTHER SERVICES

    Our Investment Services Department employs 2 investment professionals. The
Investment Services Department offers financial planning services; asset
management services through the use of unaffiliated investment managers;
retirement plans such as 401(k) plans, IRAs and SEPs; mutual funds; and the
purchase and sale of stocks and bonds on an unsolicited basis. Products
available through this department are not FDIC insured, and are not deposits or
other obligations of the Bank. These products are not guaranteed by the Bank,
and are subject to investment risk, including possible loss of principal amount
invested.

SUPERVISION AND REGULATION

GENERAL

COAST BANCORP

    Coast Bancorp, as a bank holding company, is subject to regulation under the
Bank Holding Company Act of 1956, as amended, and is registered with and subject
to the supervision of the Board of Governors of the Federal Reserve System. It
is the policy of the Federal Reserve that each bank holding company serve as a
source of financial and managerial strength to its subsidiary banks. The Federal
Reserve has the authority to examine Coast Bancorp.

    The Bank Holding Company Act requires Coast Bancorp to obtain the prior
approval of the Federal Reserve before acquisition of all or substantially all
of the assets of any bank or ownership or control of the voting shares of any
bank if, after giving effect to such acquisition, Coast Bancorp would own or
control, directly or indirectly, more than 5% of the voting shares of such bank.
Recent amendments to the Bank Holding Company Act expand the circumstances under
which a bank holding company may acquire control of or all or substantially all
of the assets of a bank located outside the State of California.

    Coast Bancorp may not engage in any business other than managing or
controlling banks or furnishing services to its subsidiaries, with the exception
of certain activities which, in the opinion of the Federal Reserve, are so
closely related to banking or to managing or controlling banks as to be
incidental to banking. Recently enacted federal legislation, known as the
Gramm-Leach-Bliley Act, offers bank holding companies an opportunity to broaden
the scope of activities engaged in by electing to be treated as a financial
holding company. A financial holding company enjoys broader powers than a bank
holding company, specifically including the ability to own securities and
insurance companies in addition to financial institutions. Coast Bancorp is
generally prohibited from acquiring direct or indirect ownership or

                                       6
<PAGE>
control of more than 5% of the voting shares of any company unless that company
is engaged in such authorized activities and the Federal Reserve approves the
acquisition.

    Coast Bancorp and its subsidiaries are prohibited from engaging in certain
tie-in arrangements in connection with any extension of credit, sale or lease of
property or provision of services. For example, with certain exceptions Coast
Commercial Bank may not condition an extension of credit on a customer obtaining
other services provided by it, Coast Bancorp or any other subsidiary, or on a
promise by the customer not to obtain other services from a competitor. In
addition, federal law imposes certain restrictions on transactions between Coast
Commercial Bank and its affiliates. As affiliates, Coast Commercial Bank and
Coast Bancorp are subject, with certain exceptions, to the provisions of federal
law imposing limitations on and requiring collateral for extensions of credit by
Coast Commercial Bank to any affiliate.

COAST COMMERCIAL BANK

    As a California state-chartered bank, Coast Commercial Bank is subject to
regulation, supervision and periodic examination by the California Department of
Financial Institutions. Coast Commercial Bank also is subject to regulation,
supervision and periodic examination by the Federal Deposit Insurance
Corporation. Coast Commercial Bank's deposits are insured by the FDIC to the
maximum amount permitted by law, which is currently $100,000 per depositor in
most cases. Insured banks are subject to FDIC regulations applicable to all
insured institutions.

    The regulations of these state and federal bank regulatory agencies govern
most aspects of Coast Commercial Bank's businesses and operations, including but
not limited to, the scope of its business, its investments, its reserves against
deposits, the nature and amount of any collateral for loans, the timing of
availability of deposited funds, the issuance of securities, the payment of
dividends, bank expansion and bank activities, including real estate development
and insurance activities, and the payment of interest on certain deposits. Coast
Commercial Bank is also subject to the requirements and restrictions of various
consumer laws, regulations and the Community Reinvestment Act.

CAPITAL STANDARDS

    The FRB, FDIC and other federal banking agencies have risk based capital
adequacy guidelines intended to provide a measure of capital adequacy that
reflects the degree of risk associated with a banking organization's operations
for both transactions reported on the balance sheet as assets, and transactions,
such as letters of credit and recourse arrangements, which are reported as
off-balance-sheet items. Under these guidelines, nominal dollar amounts of
assets and credit equivalent amounts of off-balance-sheet items are multiplied
by one of several risk adjustment percentages, which range from 0% for assets
with low credit risk, such as certain U.S. government securities, to 100% for
assets with relatively higher credit risk, such as business loans.

    A banking organization's risk based capital ratios are obtained by dividing
its qualifying capital by its total risk-adjusted assets and off-balance-sheet
items. The regulators measure risk-adjusted assets and off-balance-sheet items
against both total qualifying capital (the sum of Tier 1 capital and limited
amounts of Tier 2 capital) and Tier 1 capital. Tier 1 capital consists of common
stock, retained earnings, noncumulative perpetual preferred stock and minority
interests in certain subsidiaries, less most other intangible assets. Tier 2
capital may consist of a limited amount of the allowance for probable loan and
lease losses and certain other instruments with some characteristics of equity.
The inclusion of elements of Tier 2 capital is subject to certain other
requirements and limitations of the federal banking agencies. Since
December 31, 1992, the federal banking agencies have required a minimum ratio of
qualifying total capital to risk-adjusted assets and off-balance-sheet items of
8%, and a minimum ratio of Tier 1 capital to risk-adjusted assets and
off-balance-sheet items of 4%.

                                       7
<PAGE>
    In addition to the risk-based guidelines, federal banking regulators require
banking organizations to maintain a minimum amount of Tier 1 capital to total
assets, referred to as the leverage ratio. For a banking organization rated in
the highest of the five categories used by regulators to rate banking
organizations, the minimum leverage ratio of Tier 1 capital to total assets is
3%. It is improbable, however, that an institution with a 3% leverage ratio
would receive the highest rating by the regulators since a strong capital
position is a significant part of the regulators' rating. For all banking
organizations not rated in the highest category, the minimum leverage ratio is
at least 100 to 200 basis points above the 3% minimum. Thus, the effective
minimum leverage ratio, for all practical purposes, is at least 4% or 5%. In
addition to these uniform risk-based capital guidelines and leverage ratios that
apply across the industry, the regulators have the discretion to set individual
minimum capital requirements for specific institutions at rates significantly
above the minimum guidelines and ratios.

    See "Capital Resources" in Management's Discussion and Analysis of Financial
Condition and Results of Operations for our capital ratios at December 31, 1999.

PAYMENT OF DIVIDENDS

COAST BANCORP

    The shareholders of Coast Bancorp are entitled to receive dividends when and
as declared by its Board of Directors, out of funds legally available, subject
to the dividends preference, if any, on preferred shares that may be outstanding
and also subject to the restrictions of the California Corporations Code. At
December 31, 1999, Coast Bancorp had no outstanding shares of preferred stock.

    The principal sources of cash revenue to Coast Bancorp are dividends
received from Coast Commercial Bank. Coast Commercial Bank's ability to make
dividend payments to Coast Bancorp is subject to state and federal regulatory
restrictions.

COAST COMMERCIAL BANK

    Under state law, the Board of Directors of a California state chartered bank
may declare a cash dividend, subject to the restriction that the amount
available for the payment of cash dividends is limited to the lesser of the
bank's retained earnings, or the bank's net income for the latest three fiscal
years, less dividends previously declared during that period, or, with the
approval of the Commissioner of Financial Institutions, to the greater of the
retained earnings of the bank, the net income of the bank for its last fiscal
year or the net income of the bank for its current fiscal year.

    The FDIC has broad authority to prohibit a bank from engaging in banking
practices which it considers to be unsafe or unsound. It is possible, depending
upon the financial condition of the bank in question and other factors, that the
FDIC may assert that the payment of dividends or other payments by a bank is
considered an unsafe or unsound banking practice and therefore, implement
corrective action to address such a practice.

    Accordingly, the future payment of cash dividends by Coast Commercial Bank
will generally depend not only on Coast Commercial Bank's earnings during any
fiscal period but also on Coast Commercial Bank's meeting certain capital
requirements and the maintenance of an adequate allowances for credit losses.

COMMUNITY REINVESTMENT ACT

    Banks are subject to the Community Reinvestment Act ("CRA"), which was
enacted in 1977 to promote lending by financial institutions to individuals and
businesses located in low and moderate income areas. New CRA regulations went
into effect as of July 1, 1997. As revised the CRA regulations emphasize an
assessment of actual performance rather than of the procedures followed by a
bank, to evaluate compliance with the CRA. Overall CRA compliance continues to
be rated across a four-point scale from

                                       8
<PAGE>
"outstanding" to "substantial noncompliance," and continues to be a factor in
review of applications to merge, establish new branches or form bank holding
companies. In addition, any bank rated in "substantial noncompliance" with the
revised CRA regulations may be subject to enforcement proceedings.

    The regulations provide that "small banks", which are defined to include any
independent bank with total assets of less than $250 million, are to be
evaluated by means of a so-called "streamlined assessment method" unless such a
bank elects to be evaluated by one of the other methods provided in the
regulations. The differences between the evaluation methods may be summarized as
follows:

    (1) The "streamlined assessment method" applicable to small banks requires
that a bank's CRA compliance be evaluated pursuant to five "assessment
criteria," including its (i) loan-to-deposit ratio (as adjusted for seasonal
variations and other lending-related activities, such as sales to the secondary
market or community development lending); (ii) percentage of loans and other
lending-related activities in the bank's service area(s); (iii) distribution of
loans and other lending-related activities among borrowers of different income
levels, given the demographic characteristics of its service area(s);
(iv) geographic distribution of loans and other lending-related activities
within its service area(s); and (v) record of response to written complaints, if
any, about its CRA performance.

    (2) The "lending, investments and service tests method" is applicable to all
banks larger than $250 million which are not wholesale or limited purpose banks
and do not elect to be evaluated by the "strategic plan assessment method."
Central to this method is the requirement that such banks collect and report to
their primary federal banking regulators detailed information regarding home
mortgage, small business and farm and community development loans which is then
used to evaluate CRA compliance. At the bank's option, data regarding consumer
loans and any other loan distribution it may choose to provide also may be
collected and reported.

    Using such data, a bank will be evaluated regarding its (i) lending
performance according to the geographic distribution of its loans, the
characteristics of its borrowers, the number and complexity of its community
development loans, the innovativeness or flexibility of its lending practices to
meet low and moderate income credit needs and, at the bank's election, lending
by affiliates or through consortia or third-parties in which the bank has an
investment interest; (ii) investment performance by measure of the bank's
"qualified investments," that is, the extent to which the bank's investments,
deposits, membership shares in a credit union, or grants primarily to benefit
low or moderate income individuals and small businesses and farms, address
affordable housing or other needs not met by the private market, or assist any
minority or women-owned depository institution by donating, selling on favorable
terms or provisioning on a rent-free basis any branch of the bank located in a
predominately minority neighborhood; and (iii) service performance by evaluating
the demographic distribution of the bank's branches and ATMs, its record of
opening and closing them, the availability of alternative retail delivery
systems (such as telephone banking, banking by mail or at work, and mobile
facilities) in low and moderate income geographies and to low and moderate
income individuals, and (given the characteristics of the bank's service area(s)
and its capacity and constraints) the extent to which the bank provides
"community development services" (services which primarily benefit low and
moderate income individuals or small farms and businesses or address affordable
housing needs not met by the private market) and their innovativeness and
responsiveness.

    (3) Wholesale or limited purpose banks which do not make home mortgage,
small farm or business or consumer loans to retail customers may elect, subject
to agency approval of their status, to be evaluated by the "community
development test method," which assesses the number and amount of the bank's
community development loans, qualified investments and community development
services and their innovativeness and complexity.

    (4) Any bank may request to be evaluated by the "strategic plan assessment
method" by submitting a strategic plan for review and approval. Such a plan must
involve public participation in its preparation, and contain measurable goals
for meeting low and moderate income credit needs through lending, investments

                                       9
<PAGE>
and provision of services. Such plans generally will be evaluated by measuring
strategic plan goals against standards similar to those which will be applied in
evaluating a bank according to the "lending, investments and service test
method."

TRANSACTIONS WITH AFFILIATES

    Bank holding companies are also restricted as to the extent to which they
and their subsidiaries can borrow or otherwise obtain credit from one another,
or engage in certain other transactions. The "covered transactions" that an
insured depository institution and its subsidiaries are permitted to engage in
with their nondepository affiliates are limited to the following amounts:
(1) in the case of any one such affiliate, the aggregate amount of covered
transactions of the insured depository institution and its subsidiaries cannot
exceed 10% of the capital stock and the surplus of the insured depository
institution; and (ii) in the case of all affiliates, the aggregate amount of
covered transactions of the insured depository institution and its subsidiaries
cannot exceed 20% of the capital stock and surplus of the insured depository
institution. In addition, extensions of credit that constitute covered
transactions must be collateralized in prescribed amounts.

    "Covered transactions" are defined by statute to include a loan or extension
of credit to the affiliate, a purchase of securities issued by an affiliate, a
purchase of assets from the affiliate (unless otherwise exempted by the Federal
Reserve Board), the acceptance of securities issued by the affiliate as
collateral for a loan and the issuance of a guarantee, acceptance, or letter of
credit for the benefit of an affiliate. Further, a bank holding company and its
subsidiaries are prohibited from engaging in certain tie-in arrangements in
connection with any extension of credit, lease or sale of property or furnishing
of services.

YEAR 2000 DATA PROCESSING ISSUES

    Coast Bancorp previously recognized the material nature of the business
issues surrounding computer processing of dates into and beyond the Year 2000
and began taking corrective action as required pursuant to the interagency
statements issued by the Federal Financial Institutions Examination Council.
Management believes Coast Bancorp and Coast Commercial Bank have completed all
of the activities within their control to ensure that Coast Bancorp's and Coast
Commercial Bank's systems are Year 2000 compliant.

    Coast Bancorp's Year 2000 readiness costs were approximately $400,000. Coast
Bancorp does not currently expect to apply any further funds to address Year
2000 issues.

    Neither Coast Bancorp nor Coast Commercial Bank have experienced any
material disruptions of their internal computer systems or software applications
due to the start of the Year 2000 nor have they experienced any problems with
the computer systems or software applications of their third party vendors,
suppliers or service providers. Coast Bancorp will continue to monitor these
third parties to determine the impact, if any, on the business of Coast Bancorp
and Coast Commercial Bank and the actions either must take, if any, in the event
of non-compliance by any of these third parties. Based upon Coast Bancorp's
assessment of compliance by third parties, there does not appear to be any
material business risk posed by any such non-compliance.

    Although Coast Bancorp's Year 2000 rollover did not present any material
business disruption, there are some remaining Year 2000 related risks, including
risks due to the fact that the Year 2000 is a leap year. Management believes
that appropriate actions have been taken to address these remaining Year 2000
issues and contingency plans are in place to minimize the financial impact to
Coast Bancorp and Coast Commercial Bank. Management, however, cannot be certain
that Year 2000 issues affecting customers, suppliers or service providers of
Coast Bancorp and Coast Commercial Bank will not have a material adverse impact
on Coast Bancorp or Coast Commercial Bank.

IMPACT OF MONETARY POLICIES

    The earnings and growth of Coast Commercial Bank are subject to the
influence of domestic and foreign economic conditions, including inflation,
recession and unemployment. The earnings of Coast Commercial Bank is affected
not only by general economic conditions but also by the monetary and fiscal
policies of the United States and federal agencies, particularly the Federal
Reserve. The Federal Reserve can and does implement national monetary policy,
such as seeking to curb inflation and combat recession, by its open market
operations in United States Government securities and by its control of the
discount rates applicable to borrowings by banks from the Federal Reserve
System. The actions of the Federal Reserve in these areas influence the growth
of bank loans, investments and deposits and affect the interest rates charged on
loans and paid on deposits. The Federal Reserve's policies have had a
significant effect on the operating results of commercial banks and are expected
to continue to do so in the future. The nature and timing of any future changes
in monetary policies are not predictable.

RECENT AND PROPOSED LEGISLATION

    The operations of Coast Bancorp and Coast Commercial Bank are subject to
extensive regulation by federal, state, and local governmental authorities and
are subject to various laws and judicial and administrative decisions imposing
requirements and restrictions on part or all of their respective operations.
Coast Bancorp believes that it is in substantial compliance in all material
respects with applicable federal, state, and local laws, rules and regulations.
Because the business of Coast Bancorp and Coast Commercial Bank is highly
regulated, the laws, rules and regulations applicable to each of them are
subject to regular modification and change.

    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 and other financial institutions are frequently
made in Congress, in the California legislature and before various bank
regulatory agencies. Most recently, President Clinton signed into law the Gramm-
Leach-Bliley Act. This legislation eliminates many of the barriers that have
separated the insurance, securities and banking industries since the Great
Depression. The federal banking agencies (the Federal Reserve, FDIC, Office of
the Comptroller of the Currency) among others, are currently drafting
regulations to implement the Gramm-Leach-Bliley Act. The likelihood of any major
change from these regulations, and the impact such change may have on Coast
Bancorp and Coast Commercial Bank is impossible to predict.

    GRAMM-LEACH-BLILEY ACT

    The Gramm-Leach-Bliley Act, signed into law on November 12, 1999, is the
result of a decade of debate in the Congress regarding a fundamental reformation
of the nation's financial system. The law is subdivided into seven titles, by
functional area. Title I acts to facilitate affiliations among banks, insurance
companies and securities firms. Title II narrows the exemptions from the
securities laws previously enjoyed by banks, requires the Federal Reserve and
the SEC to work together to draft rules governing certain securities activities
of banks and creates a new, voluntary investment bank holding company. Title III
restates the proposition that the states are the functional regulators for all
insurance activities, including the insurance activities of federally-chartered
banks. The law bars the states from prohibiting insurance activities by
depository institutions. The law encourages the states to develop uniform or
reciprocal rules for the licensing of insurance agents. Title IV prohibits the
creation of additional unitary thrift holding companies. Title V imposes
significant requirements on financial institutions related to the transfer of
nonpublic personal information. These provisions require each institution to
develop and distribute to accountholders an information disclosure policy, and
requires that the policy allow customers to, and for the institution to, honor a
customer's request to "opt-out" of the proposed transfer of specified nonpublic
information to third parties. Title VI reforms the Federal Home Loan Bank system
to allow broader access

                                       11
<PAGE>
among depository institutions to the systems advance programs, and to improve
the corporate governance and capital maintenance requirements for the system.
Title VII addresses a multitude of issues including disclosure of ATM
surcharging practices, disclosure of agreements among non-governmental entities
and insured depository institutions which donate to non-governmental entities
regarding donations made in connection with the Community Reinvestment Act, and
disclosure by the recipient non-governmental entities of how such funds are
used. Additionally, the law extends the period of time between CRA examinations
of community banks.

    Coast Commercial Bank and Coast Bancorp intend to comply with all provisions
of the Gramm-Leach-Bliley Act and all implementing regulations as they become
effective, and Coast Commercial Bank intends to develop appropriate policies and
procedures to meet its responsibilities in connection with the privacy
provisions of Title V of that Act.

ACCOUNTING PRONOUNCEMENTS

    In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133". This statement defers the effective
date of Statement No. 133 "Accounting for Derivative Instruments and Hedging
Activities" for all entities, which have not yet adopted the Statement, to be
effective for all fiscal quarters of all fiscal years beginning after June 15,
2000, with earlier application encouraged.

    B.  As of February 23, 2000, the approximate number of registered holders of
our Common Stock was 387. In addition, the approximate number of beneficial
shareholders was 453.

    C.  We paid a cash dividend of $0.09 per share in the first quarter of 2000,
cash dividends of $0.08 per share in each quarter during 1999, and cash
dividends of $0.07 per share in each quarter during 1998. A two-for-one stock
split became effective February 5, 1999 and a 10% stock dividend in May 1998.

    There can be no assurances that we will pay either cash or stock dividends
in the future.

    We consider the payment of cash dividends in order to return a portion of
our profits to stockholders. In considering the amount of cash dividends to be
paid, if any, we consider the maintenance of a consistent dividend policy as
part of our efforts to make the Company's stock attractive to investors; the
amount and frequency of dividends; the payout ratio; our need to have sufficient
funds available to pay our expenses; and compliance with applicable laws,
regulations and other regulatory requirements.

    California law provides that in order to declare dividends: (i) after a
corporation has paid a dividend to its stockholders, it must be likely that the
corporation will be able to meet its liabilities as they mature; and (ii) the
amount of the corporation's retained earnings immediately prior to the payment
of the dividend must be equal to or exceed the amount of the proposed cash
dividend.

    Coast Bancorp's primary source of revenue is dividends from Coast Commercial
Bank. The payment of dividends by the bank is subject to various legal and
regulatory requirements. See Item 1 "Restrictions on Dividends and Other
Distributions."

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

    THIS DOCUMENT MAY CONTAIN FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY
FROM THOSE INDICATED. FOR A DISCUSSION OF FACTORS THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER, PLEASE SEE THE DISCUSSION CONTAINED BELOW AND IN OUR PUBLICLY
AVAILABLE SECURITIES AND EXCHANGE COMMISSION FILINGS AND PRESS RELEASES.

You should read the following discussion and analysis of our financial condition
and the results of our operations as of December 31, 1999 and 1998 and for the
three years ended December 31, 1999 together with our consolidated financial
statements and the notes to consolidated financial statements included in this
Form 10-K. This discussion should be read in conjunction with those financial
statements and the related notes. Averages presented in the following tables are
substantially all based upon daily average balances.

BUSINESS ORGANIZATION

    We are a California corporation organized in 1995 to act as the holding
company for Coast Commercial Bank, a California state chartered bank which
opened in 1982 with headquarters in Santa Cruz and branch offices in Aptos,
Santa Cruz, Scotts Valley and Watsonville. During 1995 we acquired through
merger all of the outstanding common stock of the bank. The merger was accounted
for similar to a pooling of interests in that the historical cost basis of Coast
Commercial Bank has been carried forward. We currently conduct no significant
business activities other than our investment in Coast Commercial Bank.
Consequently, substantially all of the our net income, assets and equity are
derived from our investment in Coast Commercial Bank. On December 14, 1999 Coast
Bancorp and Greater Bay Bancorp signed a definitive agreement for a merger of
the two companies. See Item 1--Business.

    We engage in commercial and consumer banking, offering a range of
traditional banking products and services to individuals, retailers, small and
medium-sized businesses and professionals, primarily within the Santa Cruz
County area.

OVERVIEW

    Net income was $6,939,000 for the year ended December 31, 1999, an increase
of 13% from 1998 net income of $6,161,000. Net income reported for 1998
represented an increase of 20% from 1997 net income of $5,155,000. On a diluted
per share basis, net income for 1999 was $1.41 compared with $1.25 and $1.05 for
the preceding two years. The increase in net income in 1999 over 1998 was
primarily the result of the increase in net interest income and a decrease in
the provision for loan losses exceeding the increase in noninterest expenses and
the decrease in noninterest income. The increase in net income in 1998 over 1997
was primarily the result of the increases in net interest income, a decrease in
the provision for loan losses and noninterest income exceeding the increase in
noninterest expenses.

EARNINGS SUMMARY

NET INTEREST INCOME

    Net interest income refers to the difference between interest and fees
earned on loans and investments and the interest paid on deposits and other
borrowed funds. It is the largest component of the net earnings of a financial
institution. The primary factors to consider in analyzing net interest income
are the composition and volume of earning assets and interest-bearing
liabilities, the amount of noninterest bearing liabilities and nonaccrual loans,
and changes in market interest rates.

    Net interest income is affected by changes in the amount and mix of
interest-earning assets and interest-bearing liabilities, referred to as "volume
change." Net interest income is also affected by changes in yields earned on
interest-earning assets and rates paid on interest-bearing liabilities, referred
to as "rate change." Table 2 presents changes in interest income and interest
expense for each major category of interest-earning assets and interest-bearing
liabilities. The table also reflects the amount of change attributable to volume
and rate changes for the years indicated on a fully taxable equivalent basis.

------------------------

(1) Changes attributable to the change in interest rate on the change in volume
    are allocated to the rate change.

    For 1999, net interest income, on a fully taxable-equivalent basis, was
$20,424,000 or 6.6% of average earning assets, an increase of 15% over
$17,729,000 or 6.6% of average earning assets in the comparable period in 1998.
The increase in 1999 reflects higher levels of earning assets as the lower
yields on earning assets were offset by the lower rates paid on interest-bearing
liabilities. Net interest income in 1998, on a fully taxable-equivalent basis,
was $17,729,000 or 6.6% of average earning assets, an increase of 15% over
$15,353,000 or 6.8% of average earning assets in the comparable period in 1997.
The increase in 1998 reflects higher levels of earning assets partially offset
by lower yields on earning assets and higher rates paid on interest-bearing
liabilities.

    Interest income, on a fully taxable-equivalent basis, was $27,697,000,
$24,492,000, and $20,980,000 for 1999, 1998 and 1997, respectively. The
increases in 1999 and 1998 resulted from the growth in average earning assets.
Loan yields averaged 10.6% in 1999, 11.2% in 1998 and 11.3% in 1997.
Approximately 78% of our loans have variable interest rates indexed to the prime
rate. Our average prime rate was 8.00%, 8.36%, and 8.44% in 1999, 1998, and
1997, respectively. Average earning assets were $310,558,000 for 1999, an
increase of 15% over $269,640,000 in 1998, which increased 19% over $226,650,000
in 1997. The growth in average earning assets resulted from increased levels of
deposits and other borrowings which were invested primarily in loans and
securities.

    The increases in interest income during 1999 and 1998, on a fully
taxable-equivalent basis, were partially offset by increases in interest
expense. The increases were primarily due to increases in interest-

                                       17

bearing deposits. The average rate paid on interest bearing deposits was 3.0% in
1999, 3.2% in 1998, and 3.0% in 1997.

</TABLE>

    Customer service fees increased in 1999 as a result of fees from the bank's
investment services department and higher deposit services and merchant card
processing fees. The 1998 decline in customer service fees from 1997 reflects a
lower volume of nonsufficient funds items and lower merchant card processing
fees due to competition in attracting and retaining merchants. Gains from sale
of loans decreased in 1999 as a result of lower prices received for the
guaranteed portion of SBA loans sold. Lower prices were a result of faster than
expected prepayments in the national market due to lower loan rates through 1998
and most of 1999. The increase in gains from sale of loans in 1998 resulted from
increased SBA loan originations during 1998 and 1997. Loan servicing fees
declined during 1999 and 1998 principally from an increase in the amortization
of capitalized SBA servicing fees in response to the increased prepayments of
the loans.

</TABLE>

    Total noninterest expenses of $13,372,000 increased $890,000 or 7% in 1999
over $12,482,000 in 1998, which increased $1,476,000 or 13% in 1998 over
$11,006,000 in 1997.

    The 1999 increase resulted from costs associated to support the growth in
total loans, deposits and assets. The 1998 increase resulted from costs
associated with opening a sixth branch and other staffing increases. The
decrease in noninterest expenses as a percentage of average earning assets is
the result of the rate of growth in average earning assets in 1999 and 1998
exceeding the rate of increase in noninterest expenses.

INCOME TAXES

    Our effective tax rate was 38.7% for 1999 compared to 41.7% for 1998 and
40.4% for 1997. Changes in our effective tax rate are primarily due to
fluctuations in the proportion of tax exempt income generated from investment
securities to pre-tax income.

BALANCE SHEET ANALYSIS

    Total assets increased to $370.0 million at December 31, 1999, a 14%
increase from the end of 1998. Total assets increased to $324.7 million in 1998,
a 24% increase from the $261.5 million a year earlier. Based on average
balances, 1999 average total assets of $335.2 million represent an increase of
15% over 1998 average total assets of $292.2 million which represent an increase
of 18% over 1997.

EARNING ASSETS

LOANS

    Total gross loans at December 31, 1999 were $212.1 million, a 32% increase
from $161.0 million at December 31, 1998 which was a 10% increase from
$146.4 million at December 31, 1997.

</TABLE>

    Average loans in 1999 were $183,035,000 representing an increase of
$31,661,000 or 21% over $151,374,000 in 1998, which represents an increase of
$22,400,000, or 17% over 1997. The 1999 and 1998 increases reflect growth in
average real estate loans, which, in the opinion of management is due to
improved local economic conditions.

    Commercial loans were $35,023,000 at the end of 1999 compared to $38,874,000
and $42,838,000 at the end of 1998 and 1997, respectively. We make commercial
loans primarily to serve the short- to medium-term credit demands of
small-to-medium sized businesses and professionals located in Santa Cruz County
for lines of credit, single payment and term debt obligations. Typically, loans
are collateralized by the working capital, inventory, receivables, or equipment
being financed or other assets available to the borrower. Our commercial loan
portfolio is diversified as to industries and types of businesses with no
material industry concentrations and a profile which we believe generally
reflects the economy of Santa Cruz County. Risks include those outlined in the
Risk Elements section below.

    Real estate mortgage loans were $130,438,000 at December 31, 1999 compared
to $95,360,000 and $76,101,000 at the end of 1998 and 1997, respectively. The
increases of $35,078,000 in 1999, $19,259,000 in 1998 and $10,893,000 in 1997
resulted from the retained portion of SBA loans and additional loan demand for
nonresidential real estate financing in our market area. Extensions of credit
are based on an analysis of the borrower's ability to generate debt service,
obtain other financing or sell the property. Advances on nonresidential
properties are limited in general to approximately 70% of the lower of cost or
appraised value.

    Our real estate construction loan portfolio was $42,023,000 at December 31,
1999, compared to $22,206,000 and $21,376,000 at the end of 1998 and 1997,
respectively. Construction loans represented 20% of total loans at December 31,
1999 compared to 14% and 15% in 1998 and 1997. We finance the construction of
commercial and residential properties. These loans are at variable rates,
generally have maturities of less than 12 months, and are secured by first deeds
of trust on the underlying properties. Repayment is expected from the borrower's
ability to obtain take-out financing or sell the property. Advances on
residential and commercial projects are limited in general to the lower of
approximately 80% and 70%, respectively, of cost or appraised value of the
collateral.

    Real estate mortgage and construction lending entail potential risks which
are not inherent in other types of loans. These potential risks include declines
in market values of underlying real property collateral and, with respect to
construction lending, delays or cost overruns which could expose us to loss. In
addition, risks in commercial real estate lending include declines in commercial
real estate values, general economic conditions surrounding the commercial real
estate properties, and vacancy rates. A decline in the general economic
conditions or real estate values within the Company's market area could have a
negative impact on the performance of the loan portfolio or value of the
collateral. Because we lend primarily within our market area, the real property
collateral for our loans is similarly concentrated, rather than diversified over
a broader geographic area. We could therefore be adversely affected by a decline
in

                                       20
<PAGE>
real estate values in our target market, even if real estate values elsewhere in
California generally remained stable or increased. Risks also include those
outlined in the Risk Elements section below.

    Installment loans were $4,592,000 compared to $4,536,000 and $6,112,000 at
the end of 1999, 1998, and 1997, respectively. The installment loan portfolio
finances customers' household, family and other personal expenditures on both a
secured and unsecured basis. Risks include those outlined in the Risk Elements
section below.

RISK ELEMENTS

    Lending money involves an inherent risk of nonpayment. Through the
administration of loan policies and monitoring of the portfolio, management
seeks to reduce such risks. The allowance for credit losses is an estimate to
provide amounts for probable losses, both identified and unidentified, in the
loan portfolio.

    Management strives to achieve a low level of credit losses by continuing
emphasis on credit quality in the loan approval process, active credit
administration and regular monitoring. An important tool in achieving a high
level of credit quality is the loan grading system to assess the risk inherent
in each loan. Additionally, management believes our ability to manage portfolio
credit risk is enhanced by lending personnel's knowledge of our service area.
Our directors, senior managers and lending personnel live in the communities we
serve and are active members of civic, charitable and service groups in our
communities. Further, we have experienced minimal turnover of senior management
since the inception of Coast Commercial Bank in 1982.

    Ultimately, credit quality may be influenced by underlying trends in
economic and business cycles. Management believes that our lending policies and
underwriting standards will tend to minimize losses in an economic downturn,
however, there is no assurance that losses will be limited under such
circumstances. Our loan policies and underwriting standards include, but are not
limited to, the following: 1) maintaining a thorough understanding of our
service area and limiting investments outside of this area, 2) maintaining a
thorough understanding of the borrowers' knowledge and capacity in their field
of expertise, 3) basing real estate construction loan approval not only on
marketability of the project, but also on the borrowers' capacity to support the
project financially in the event it does not sell within the original projected
time period, and 4) maintaining conforming and prudent loan to value and loan to
cost ratios based on independent outside appraisals and ongoing inspection and
analysis by our construction lending officers. In addition, we strive to
diversify the risk inherent in the construction portfolio by avoiding
concentrations to individual borrowers and on any one project.

    Management regularly reviews and monitors the loan portfolio to determine
the risk profile of each credit, and to identify credits whose risk profiles
have changed. This review includes, but is not limited to, such factors as
payment status, the financial condition of the borrower, borrower compliance
with loan covenants, underlying collateral values, potential loan
concentrations, and general economic conditions. When potential problem credits
are identified by management, action plans for each credit are developed for our
personnel to mitigate the credit risk through measures such as increased
monitoring, debt reduction goals, additional collateral and possible credit
restructuring opportunities.

NONACCRUAL LOANS, LOANS PAST DUE AND OREO

    The accrual of interest is discontinued and any accrued and unpaid interest
is reversed when the payment of principal or interest is 90 days past due unless
the amount is well secured and in the process of collection. Income on such
loans is then recognized only to the extent that cash is received and where the
future collection of principal is probable. At December 31, 1999 nonaccrual
loans totaled $1,098,000 or .5% of total loans compared to $1,108,000 or .7% at
December 31, 1998 and $266,000 or .2% at December 31, 1997. Nonaccrual loans at
December 31, 1999 consist primarily of one commercial real estate term loan. If
the nonaccrual loans at December 31, 1999 had not been on nonaccrual, $184,000
of interest income would have been realized in 1999. We realized $2,000 on these
nonaccrual loans in 1999.

    There were no loans at December 31, 1999 where management had serious doubts
about the borrower's ability to comply with loan repayment terms and which may
result in disclosure as a nonaccrual, past due or restructured loan, except as
disclosed in Table 6.

PROVISION AND ALLOWANCE FOR CREDIT LOSSES

    Management has established an evaluation process designed to determine the
adequacy of the allowance for credit losses. This process attempts to assess the
risk of loss inherent in the portfolio by segregating the allowance for credit
losses into three components: "historical losses;" "specific;" and "margin for
imprecision." The "historical losses" component is calculated as a function of
the prior four years' loss experience for commercial, real estate and consumer
loan types. The four years are assigned weightings of 35%, 30%, 20% and 15%
beginning with the most recent year. The "specific" component is established by
allocating a portion of the allowance to individual classified credits on the
basis of specific circumstances and assessments. The "margin for imprecision"
component is an unallocated portion that supplements the first two components as
a margin to guard against unforeseen factors. The "historical losses" and
"specific" components include management's judgment of the effect of economic
conditions on the ability of our borrowers to repay; an evaluation of the
allowance for credit losses in relation to the size of the overall loan
portfolio; an evaluation of the composition of, and growth trends within, the
loan portfolio; consideration of the relationship of the allowance for credit
losses to nonperforming loans; net charge-off trends; and other factors. While
this evaluation process utilizes historical and other objective information, the
classification of loans and the establishment of the allowance for credit losses
relies, to a great extent, on the judgment and experience of management. We
evaluate the adequacy of our allowance for credit losses quarterly.

    There were no impaired loans at December 31, 1999, 1998 and 1997.
Additionally, there were no impaired loans during 1999, 1998 and 1997.

                                       22
<PAGE>
    The allowance for credit losses totaled $3,726,000 or 1.8% of total loans as
of December 31, 1999 compared to $3,871,000 or 2.4% of total loans as of
December 31, 1998, and $3,609,000 or 2.5% as of December 31, 1997. It is the
policy of management to maintain the allowance for credit losses at a level
adequate for known and inherent risks in the loan portfolio. Based on
information currently available to analyze loan loss potential, including
economic factors, overall credit quality, historical delinquency and a history
of actual charge-offs, management believes that the loan loss provision and
allowance are adequate; however, no assurance of the ultimate level of credit
losses can be given with any certainty. Loans are charged against the allowance
when management believes that the collectibility of the principal is unlikely.
An analysis of activity in the allowance for credit losses is presented in Table
7.

    The allocation for real estate includes real estate construction and real

credit losses separately for real estate construction and real estate term
loans.

OTHER INTEREST EARNING ASSETS

    The average balance of securities and federal funds sold increased
$9,257,000 to $127,523,000 in 1999. The average balance of securities and
federal funds sold totaled $118,266,000 in 1998, an increase of $20,590,000 from
$97,676,000 in 1997. The 1999 and 1998 increases resulted from deploying
additional liquidity in the securities portfolio. Sources of the additional
liquidity were borrowed funds and the excess of the increase in average deposits
over the increase in average loans. Management uses borrowed funds to increase
earning assets and enhance our interest rate risk profile.

FUNDING

    Deposits represent our principal source of funds for investment. Deposits
are primarily core deposits in that they are demand, savings, and time deposits
under $100,000 generated from local businesses and individuals. These sources
represent relatively stable, long term deposit relationships which minimize
fluctuations in overall deposit balances. We accept time deposits from the State
of California to replace other borrowed funds. The State of California time
deposit is renewable approximately every three months at a rate similar to the
three month U.S. Treasury bill rate. The amount of time deposits from the State
of California was $20,000,000 and $15,000,000 at December 31, 1999 and 1998. We
have never used brokered deposits. Table 9 presents the composition of deposits
for the five years ended December 31, 1999.

Average total deposits in 1999 of $277,711,000 showed an increase of $38,879,000
or 16% over the 1998 average of $238,832,000 which was an increase of
$45,572,000 or 24% over 1997. During 1999, average interest-bearing deposits
increased $31,411,000 and average non-interest bearing deposits increased
$7,468,000 over 1998.

    Another source of funding is borrowed funds. Management uses borrowed funds
to increase earning assets, prudently leverage capital and minimize our interest
rate risk. Typically, these funds result from the use of advances from the FHLB
and agreements to sell securities with repurchase at a designated future date,
also known as repurchase agreements. The average balance of borrowed funds was
$20,714,000 and $21,629,000 during 1999 and 1998. The weighted average interest
rate for 1999 was 5.3% and for 1998 was 5.4%. The maximum amount of borrowings
at any month-end during 1999 was $31,500,000. The weighted average interest rate
on borrowed funds outstanding at December 31, 1999 and 1998 was 5.6% and 5.0%.
Repurchase agreements are conducted with major banks and investment brokerage
firms. The maturity of these arrangements is typically 30 to 90 days. Advances
from the FHLB may vary in maturity from 1 to 10 years. We sometimes negotiate
advances from the FHLB that permit the FHLB to call the advance prior to
maturity. At December 31, 1999, advances callable by the FHLB totaled
$15,000,000 with $5,000,000 at 4.71% callable beginning in March 2000 and
$10,000,000 at 5.75% callable beginning in November 2000.

LIQUIDITY AND INTEREST RATE SENSITIVITY

    Liquidity management refers to our ability to provide funds on an ongoing
basis to meet fluctuations in deposit levels as well as the credit needs and
requirements of our clients. Both assets and liabilities contribute to our
liquidity position. Federal funds lines, short-term investments and securities,
and loan repayments contribute to liquidity, along with deposit increases, while
loan funding and deposit withdrawals decrease liquidity. We assess the
likelihood of projected funding requirements by reviewing historical funding
patterns, current and forecasted economic conditions and individual client
funding needs. We maintain informal lines of credit with our correspondent banks
for short-term liquidity needs. These informal lines of credit are not committed
facilities by the correspondent banks and no fees are paid to maintain them.

    We manage our liquidity by maintaining a majority of our investment
portfolio in liquid investments in addition to our federal funds sold. Liquidity
is measured by various ratios, including the liquidity ratio which reflects net
liquid assets as a percent of total assets. As of December 31, 1999, this ratio
was 13.4%. Other key liquidity ratios are the ratios of gross loans to deposits
and federal funds sold to deposits, which were 70.6% and 5.0%, respectively, as
of December 31, 1999.

INTEREST RATE SENSITIVITY

    Interest rate sensitivity is a measure of the exposure of our future
earnings due to changes in interest rates. If assets and liabilities do not
reprice simultaneously and in equal volumes, the potential for such exposure
exists. It is management's objective to achieve a modestly asset-sensitive
position, such that our net interest margin increases as market interest rates
rise and decreases when rates decline.

    One quantitative measure of the "mismatch" between asset and liability
repricing is the interest rate sensitivity "gap". All interest-earning assets
and funding sources are classified as to their expected repricing or maturity
date, whichever is sooner. Within each time period, the difference between asset
and liability balances, or "gap," is calculated. Positive cumulative gaps in
early time periods suggest that earnings will increase if interest rates rise.
Negative gaps suggest that earnings will decline when interest rates rise. Table
10 presents our gap analyses at December 31, 1999. Mortgage backed securities
are reported in the period of their expected repricing based upon estimated
prepayments developed from recent experience.

    Our positive cumulative total gap results from the exclusion from the above
table of noninterest-bearing demand deposits, which represent a significant
portion of our funding sources. We maintain a positive cumulative gap in all
time periods except next day and within 3 months and the over 3 months and
within one year periods. Our experience indicates money market deposit rates
tend to lag changes in the prime rate which immediately impact the prime
rate-based loan portfolio. Even in our negative gap time periods, rising rates
tend to result in an increase in net interest income. Should interest rates
stabilize or decline in future periods, it is reasonable to assume that our net
interest margin, as well as net interest income, may decline correspondingly.

CAPITAL RESOURCES

    Management seeks to maintain adequate capital to support anticipated asset
growth and credit risks, and to ensure that we are in compliance with all
regulatory capital guidelines. Our primary source of new capital has been the
retention of earnings. Stockholders' equity was $33,039,000 at December 31,
1999, an increase of $2,842,000, or 9% from $30,197,000 at December 31, 1998.
This increase was due to 1999 earnings of $6,939,000 and proceeds related to
stock option exercises of $773,000, offset by cash distributions of $1,534,000
and a decrease in the net after-tax unrealized gain on securities
available-for-sale of $3,336,000. We do not have any material commitments for
capital expenditures as of December 31, 1999.

    We pay a quarterly cash dividend on our common stock as part of efforts to
enhance stockholder value. Our goal is to maintain a strong capital position
that will permit payment of a consistent cash dividend which grows commensurate
with earnings growth.

    During 1997, the Board of Directors approved a stock repurchase program
authorizing open market purchases of up to 145,837 of the outstanding shares, or
approximately 3%, in order to enhance long term stockholder value. As of
December 31, 1998, 145,500 shares had been acquired for a total purchase price
of $2,781,000. No shares were repurchased in 1999.

    We are subject to capital adequacy guidelines issued by the federal bank
regulatory authorities. Under these guidelines, the minimum total risk-based
capital requirement is 10.0% of risk-weighted assets and certain off-balance
sheet items for a "well capitalized" depository institution. At least 6.0% of
the 10.0% total risk-based capital ratio must consist of Tier 1 capital, defined
as tangible common equity, and the remainder may consist of subordinated debt,
cumulative preferred stock and a limited amount of the allowance for loan
losses.

    The federal regulatory authorities have established minimum capital leverage
ratio guidelines for state banks. The ratio is determined using Tier 1 capital
divided by quarterly average total assets. The guidelines require a minimum of
5.0% for a "well capitalized" depository institution.

    Our risk-based and leverage capital ratios were in excess of regulatory

Notes to Consolidated Financial Statements.

EFFECTS OF INFLATION

    The impact of inflation on a financial institution differs significantly
from that exerted on manufacturing, or other commercial concerns, primarily
because its assets and liabilities are largely monetary. In general, inflation
primarily affects us indirectly through its effect of increasing market rates of
interest. However, our earnings are affected by the spread between the yield on
earning assets and rates paid on interest-bearing liabilities rather than the
absolute level of interest rates. Additionally, there may be some upward
pressure on our operating expenses, such as adjustments in salaries and benefits
and occupancy expense, based upon consumer price indices. In the opinion of
management, inflation has not had a material effect on the consolidated
financial statements for the years ended December 31, 1999, 1998 and 1997.
Changes in interest rates are highly sensitive to many factors which are beyond
the control of management. Changes in interest rates will influence the growth
of loans, investments and deposits, as well as the rates charged on loans and
paid on deposits. The nature, timing and impact of future changes in interest
rates or monetary and fiscal policies are not predictable.

YEAR 2000

    Coast Bancorp previously recognized the material nature of the business
issues surrounding computer processing of dates into and beyond the Year 2000
and began taking corrective action as required pursuant to the interagency
statements issued by the Federal Financial Institutions Examination Council.
Management believes Coast Bancorp and Coast Commercial Bank have completed all
of the activities within their control to ensure that Coast Bancorp's and Coast
Commercial Bank's systems are Year 2000 compliant.

    Coast Bancorp's Year 2000 readiness costs were approximately $400,000. Coast
Bancorp does not currently expect to apply any further funds to address Year
2000 issues.

    Neither Coast Bancorp nor Coast Commercial Bank have experienced any
material disruptions of their internal computer systems or software applications
due to the start of the Year 2000 nor have they experienced any problems with
the computer systems or software applications of their third party vendors,
suppliers or service providers. Coast Bancorp will continue to monitor these
third parties to determine the impact, if any, on the business of Coast Bancorp
and Coast Commercial Bank and the actions either must take, if any, in the event
of non-compliance by any of these third parties. Based upon Coast Bancorp's

                                       29
<PAGE>
assessment of compliance by third parties, there does not appear to be any
material business risk posed by any such non-compliance.

    Although Coast Bancorp's Year 2000 rollover did not present any material
business disruption, there are some remaining Year 2000 related risks, including
risks due to the fact that the Year 2000 is a leap year. Management believes
that appropriate actions have been taken to address these remaining Year 2000
issues and contingency plans are in place to minimize the financial impact to
Coast Bancorp and Coast Commercial Bank. Management, however, cannot be certain
that Year 2000 issues affecting customers, suppliers or service providers of
Coast Bancorp and Coast Commercial Bank will not have a material adverse impact
on Coast Bancorp or Coast Commercial Bank.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    The information under Item 7 of this Report under the Caption "Interest Rate
Sensitivity" is incorporated herein by reference.

    Our profitability is dependent to a large extent upon our net interest
income, which is the difference between our interest income on earning assets,
such as loans and securities, and our interest expense on interest-bearing
liabilities, such as deposits and borrowings. We, like other financial
institutions, are subject to interest rate risk to the degree that our
interest-earning assets reprice differently than our interest-bearing
liabilities. We manage our mix of assets and liabilities with the goals of
limiting our exposure to interest rate risk, maintaining adequate liquidity, and
coordinating our sources and uses of funds. Specific strategies have included
increasing the volume of fixed rate securities funded in part by borrowings such
as repurchase agreements.

    We seek to control our interest rate risk exposure in a manner that will
allow for adequate levels of earnings and capital over a range of possible
interest rate environments. We have adopted formal policies and practices to
monitor and manage interest rate risk exposure. As part of this effort, we use
the market value of portfolio equity (MVPE) methodology to gauge interest rate
risk exposure.

    Generally, MVPE is the discounted present value of the difference between
incoming cash flows on interest-earning assets and other assets and outgoing
cash flows on interest-bearing liabilities and other liabilities. The
application of the methodology attempts to quantify interest rate risk as the
change in MVPE which would result from a theoretical 200 basis point (1 basis
point equals .01%) change in market interest rates. Both 200 basis point
increases and decreases in market rates are considered.

    The following table, as of December 31, 1999 and 1998, is an analysis of our
interest rate risk as measured by changes in MVPE for instantaneous and
sustained parallel shifts of 200 basis points in market interest rates.

</TABLE>

    The above table illustrates, for example, that an instantaneous 200 basis
point increase in market interest rates at December 31, 1999 would reduce our
MVPE by approximately $2.1 million at that date.

    Management believes the MVPE methodology overcomes three shortcomings of the
typical maturity gap methodology. First, it does not use arbitrary repricing
intervals and accounts for all expected future cash flows, weighting each by its
appropriate discount factor. Second, because the MVPE method projects cash flows
of each financial instrument under different interest-rate environments, it can
incorporate the effect of embedded options on an institution's interest rate
risk exposure. Third, it allows interest rates on

                                       30
<PAGE>
different instruments to change by varying amounts in response to a change in
market interest rates, resulting in more accurate estimates of cash flows.

    However, as with any method of gauging interest rate risk, there are certain
shortcomings inherent to the MVPE methodology. The model assumes interest rate
changes are instantaneous parallel shifts in the yield curve. In reality, rate
changes are rarely instantaneous. The use of the simplifying assumption that
short-term and long-term rates change by the same degree may also misstate
historic rate patterns, which rarely show parallel yield curve shifts. Further,
the model assumes that certain assets and liabilities of similar maturity or
period to repricing will react the same to changes in rates. In reality, certain
types of financial instruments may react in advance of changes in market rates,
while the reaction of other types of financial instruments may lag behind the
change in general market rates. Additionally, the MVPE methodology may not
reflect the full impact of annual and lifetime restrictions on changes in rates
for certain assets, such as adjustable-rate mortgages. When interests rates
change, actual loan prepayments and actual early withdrawals from certificates
of deposit may deviate significantly from assumptions used in the model.
Finally, this methodology does not measure or reflect the impact that higher
rates may have on variable or adjustable-rate loan customers' ability to service
their debt. All of these factors are to be considered in monitoring our exposure
to interest rate risk.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION--In May 1995, the stockholders of Coast Commercial Bank (the
Bank) approved a plan which provided for the formation of Coast Bancorp (a bank
holding company) (the Company) and the conversion of each share of outstanding
Bank common stock into one share of Company common stock. Effective July 25,
1995 the Company issued 4,555,998 shares of its common stock for all the
outstanding shares of the Bank through a merger which has been accounted for
similar to a pooling of interests in that the historical cost basis of the Bank
has been carried forward. As a result of the merger, the Bank became a
wholly-owned subsidiary of the Company.

    On January 20, 1999, the Company's board of directors approved the
declaration of a 2-for-1 stock split effective for shareholders of record
February 5, 1999. Accordingly, all historical financial information has been
restated as if the stock split had been in effect for all periods presented.

    NATURE OF OPERATIONS--The Company and its subsidiary, Coast Commercial Bank,
operate 6 branches in Santa Cruz County, California. The Company's primary
source of revenue is loans to customers, who are predominately small and
middle-market businesses, professionals and middle-income individuals in Santa
Cruz County. Banking products and services offered include commercial and
consumer banking services such as commercial, construction, real estate, SBA
guaranteed, personal, home equity and other consumer loans as well as checking
and savings accounts, time deposits, overdraft protection, credit and debit
cards, merchant credit card processing, safe deposit boxes and related services.

    On December 14, 1999 the Company and Greater Bay Bancorp, the parent of
Cupertino National Bank, Mid-Peninsula Bank, Peninsula Bank of Commerce, Golden
Gate Bank, Bay Area Bank, Bay Bank of Commerce and Mt. Diablo National Bank,
signed a definitive agreement for a merger of the two companies. The agreement
provides for the Company's shareholders to receive shares of Greater Bay Bancorp
stock, based on the average price of Greater Bay's stock during a 20 trading day
period preceding the effective date of the merger, in a tax-free exchange to be
accounted for as a pooling of interests. Assuming the price of Greater Bay's
stock as of December 31, 1999 equaled the average price of Greater Bay's stock
during a 20 trading day period preceding the effective date of the merger, Coast
Bancorp's shareholders would receive approximately 3,072,000 shares of Greater
Bay Bancorp stock. The transaction is expected to be completed in the second
quarter of 2000 subject to approval of the transaction by the Company's and
Greater Bay's shareholders and receipt of regulatory approvals.

    BASIS OF PRESENTATION--The accounting and reporting policies of the Company
and the Bank conform to generally accepted accounting principles and to
prevailing practices within the banking industry. The methods of applying those
principles which materially affect the consolidated financial statements are
summarized below. In preparing financial statements in conformity with generally
accepted accounting principles, management is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities, as of the dates of the balance
sheets, and revenues and expenses for the periods indicated. The allowance for
credit losses is a material estimate. Actual results could differ from those
estimates.

    CONSOLIDATION--The consolidated financial statements include the accounts of
the Company and the Bank. All material intercompany accounts and transactions
have been eliminated.

    CASH AND EQUIVALENTS--For purposes of reporting cash flows, cash and
equivalents include cash on hand, amounts due from banks and federal funds sold.
Generally, federal funds are sold for one-day periods.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SECURITIES--At the time of purchase, investments in debt and equity
securities are classified as held-to-maturity and measured at amortized cost
only if the Company has the positive intent and ability to hold such securities
to maturity. All other investments in debt and equity securities are classified
as available-for-sale, which are carried at market value with a corresponding
recognition of the unrealized holding gain or loss, net of income taxes, as a
net amount within accumulated other comprehensive income, which is a separate
component of stockholders' equity, until realized.

    Amortization of premiums and accretion of discounts arising at acquisition
of securities are included in income using methods that approximate the interest
method. Market values are based on quoted market prices or dealer quotes. Gains
or losses on the sale of securities are computed using the specific
identification method.

    LOANS--Loans are stated at principal amount outstanding. Loans held for sale
are carried at the lower of cost or market. Interest on loans is credited to
income as earned.

    The accrual of interest is discontinued and any accrued and unpaid interest
is reversed when the payment of principal or interest is 90 days past due unless
the amount is well secured and in the process of collection. Income on
nonaccrual loans is then recognized only to the extent that cash is received and
where the future collection of principal is probable.

    The Bank measures impaired loans based upon the present value of expected
future cash flows discounted at the loan's effective interest rate, except that
as a practical expedient, an impairment may be measured based on a loan's
observable market price or the fair value of the collateral if the loan is
collateral dependent. A loan is impaired when, based upon current information
and events, it is probable that the Bank will be unable to collect all amounts
due according to the contractual terms of the loan agreement.

    Loan origination fees and costs are deferred and amortized to income by a
method approximating the effective interest method over the estimated lives of
the underlying loans. Fees received by the Company relating to mortgage loans
held for sale are recognized when the loans are sold.

    The Company originates loans that are guaranteed in part by the Small
Business Administration (SBA). The guaranteed portion of such loans can be sold
without recourse. The Company retains the servicing for the portion sold and has
credit risk for the remaining unguaranteed portion. Gains or losses realized on
loans sold are determined by allocating the recorded investment between the
portion of the loan sold and the portion retained based on an estimate of the
relative fair values of those portions as of the date the loan is sold.

    The Company also originates and sells residential mortgage loans to the
Federal Home Loan Mortgage Corporation (FHLMC) and other participants in the
mortgage markets.

    ALLOWANCE FOR CREDIT LOSSES--The Company maintains an allowance for credit
losses to absorb losses inherent in existing loans and commitments to extend
credit. The allowance is based on quarterly evaluations of collectibility and
prior loan loss experience. The evaluations take into consideration factors such
as specific problem graded loans, impaired loans, and local economic conditions
that may affect the borrowers' ability to pay. The allowance is increased by a
provision for credit losses, which is charged to current period operating
results, and decreased by the amount of chargeoffs, net of recoveries. Loans are
charged against the allowance when management believes that the collectibility
of the principal is unlikely.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The allowance also incorporates the results of measuring impaired loans by
adjusting an allocation of the existing allowance for credit losses.

    In evaluating the probability of collection, management is required to make
estimates and assumptions that affect the reported amounts of loans, allowance
for credit losses and the provision for credit losses charged to operations.
Actual results could differ significantly from those estimates.

    BANK PREMISES AND EQUIPMENT--Bank premises and equipment are stated at cost
less accumulated depreciation and amortization. Depreciation and amortization
are computed on a straight-line basis over the estimated useful lives of three
to twenty years. The Company evaluates the recoverability of long-lived assets
on an ongoing basis.

    OTHER REAL ESTATE OWNED--Other real estate owned consists of property
acquired as a result of a foreclosure proceeding or through receipt of a
deed-in-lieu of foreclosure. Other real estate owned is carried at the lower of
cost or fair value less estimated costs to sell. Any excess of the loan balance
over the fair value when the property is acquired is charged to the allowance
for credit losses. Subsequent declines in fair value, if any, and disposition
gains and losses are included in noninterest income and noninterest expenses.

    ACCRUED INTEREST RECEIVABLE AND OTHER ASSETS--Accrued interest receivable
and other assets includes the cash surrender value of single premium insurance
policies of $7,064,000 and $2,455,000 at December 31, 1999 and 1998,
respectively.

    ACCOUNTING FOR TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND
LIABILITIES--The Company accounts for the transfer and servicing of financial
assets based on the financial and servicing assets it controls and liabilities
it has incurred, derecognizes financial assets when control has been
surrendered, and derecognizes liabilities when extinguished. Servicing assets
are measured at fair value and amortized over the period of net servicing income
and are assessed for impairment on an ongoing basis. Any servicing assets in
excess of the contractually specified servicing fees are measured at fair value
as an interest-only strip receivable and treated as similar to an
available-for-sale security. Servicing assets, net of any required valuation
allowance, and interest-only strip receivables are included in other assets.

    INCOME TAXES--Income taxes are provided at current rates. Deferred income
taxes reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and amounts
used for income tax purposes.

    STOCK-BASED COMPENSATION--The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board Opinion (APB) No. 25, "Accounting for Stock Issued to
Employees." Under the intrinsic value method, compensation cost is measured as
the amount by which the quoted market value of the Company's stock at the date
of grant exceeds the stock option exercise price.

    NET INCOME PER SHARE--Basic net income per share is computed by dividing net
income by the number of weighted average common shares outstanding. Diluted net
income per share reflects potential dilution from outstanding stock options,
using the treasury stock method. There was no difference in the net income used
in the calculation of basic and diluted net income per share for 1999, 1998 and
1997. The

    COMPREHENSIVE INCOME--The Company has retroactively adopted SFAS No. 130,
"Reporting Comprehensive Income", which requires that an enterprise report and
display, by major components and as a single total, the change in its net assets
during the period fron non-owner sources. The adoption of this statement
resulted in a change in the financial statement presentation, but did not have
an impact on the Company's consolidated financial position, results of
operations or cash flows.

    SEGMENT REPORTING-- Coast Bancorp's only operating unit is Coast Commercial
Bank, a commercial bank, which offers banking products to customers located in
Santa Cruz and surrounding counties of Northern California. Accordingly,
management evaluates the Company's performance as a whole and does not allocate
resources based on the performance of different lending or transaction
activities and the Company operates as one business segment.

    RECLASSIFICATIONS--Certain amounts in the 1998 and 1997 financial statements
have been reclassified to conform to the 1999 presentation. These
reclassifications had no impact on stockholders' equity or net income.

    NEW ACCOUNTING PRONOUNCEMENTS--In June 1999, the Financial Accounting
Standards Board issued SFAS No. 137, "Accounting for Derivative Instruments and
Hedging Activities--Deferral of the Effective Date of FASB Statement No. 133".
This statement defers the effective date of Statement No. 133 "Accounting for
Derivative Instruments and Hedging Activities" for all entities, which have not
yet adopted the Statement, to be effective for all fiscal quarters of all fiscal
years beginning after June 15, 2000, with earlier application encouraged.

2. RESTRICTED CASH BALANCES

    The Company, through its bank subsidiary, is required to maintain reserves
with the Federal Reserve Bank of San Francisco. Reserve requirements are based
on a percentage of certain deposits. At December 31, 1999 the Company maintained
reserves of $1,479,000 in the form of vault cash and balances at the Federal
Reserve which satisfied the regulatory requirements.

    Nonaccrual loans were $1,098,000, $1,108,000, and $266,000 at December 31,
1999, 1998, and 1997, respectively. If interest on nonaccrual loans had been
accrued, such income would have approximated $184,000 in 1999, $124,000 in 1998
and $24,000 in 1997. Interest income of $2,000 in 1999, $74,000 in 1998 and
$18,000 in 1997 was recorded when it was received on nonaccrual loans.

    There were no impaired loans at December 31, 1999, 1998, and 1997 or during
1999, 1998 and 1997.

5. LOAN SALES AND SERVICING

    Sales of SBA loans totaled $18,214,000, $25,601,000, and $13,431,000 in
1999, 1998, and 1997. SBA loans serviced for other investors were $83,320,000
and $89,114,000 at December 31, 1999 and 1998. Sales of residential mortgage
loans totaled $56,206,000, $57,268,000, and $34,824,000 in 1999, 1998, and 1997.
Residential mortgage loans serviced for other investors were $35,144,000 and
$38,078,000 at December 31, 1999 and 1998.

    SBA loans held for sale were $11,218,000 and $6,349,000 at December 31, 1999
and 1998. Mortgage loans held by the Company pending completion of their sale to
the FHLMC or other investors were $2,804,000 and $9,242,000 at December 31, 1999
and 1998. The Company does not anticipate any loss on the sale of SBA loans.
Loans held for or pending completion of sale are included in loans in the
consolidated balance sheets. SBA loans are carried at cost, which is lower than
market value while mortgage loans are carried at the lower of cost or market
value.

    At December 31, 1999 the balance of servicing assets generated by the sale
of loans was $1,043,000, which approximates market value. Interest-only strip
receivables were recorded at $907,000 including an unrealized gain of $34,000.
These assets represent the servicing spread generated from the sold guaranteed
portions of SBA loans. Servicing income from these loans was $691,000, $839,000
and $1,038,000 in 1999, 1998 and 1997. Amortization of the related assets for
these same periods was $430,000, $267,000 and $27,000. In recording the initial
value of the servicing assets and interest-only strip receivable, the Company
uses estimates which are made based on expectations of future prepayment rates
and other considerations. If actual prepayments with respect to sold loans occur
more quickly than projected the carrying value of the servicing assets may have
to be adjusted through a charge to earnings. A decrease in

    The Bank also receives advances from the FHLB payable at maturity in
5 years, callable at the option of the FHLB beginning one year after funding the
advance. A $5,000,000 advance may be called beginning in March 2000 and a
$10,000,000 advance may be called beginning in November 2000. The weighted
average interest rate on the callable advances outstanding at December 31, 1999
was 5.4%. The securities sold under agreements to repurchase at December 31,
1999 mature within three months.

    Mortgage-backed securities were delivered to the broker-dealers who arranged
the transactions to secure the advances and securities sold under agreements to
repurchase (See Note 3).

    In order to receive advances and sell securities under agreements to
repurchase from the FHLB, the Bank is required to own capital stock of the FHLB
(See Note 3).

10. COMMITMENTS AND CONTINGENT LIABILITIES

    In the normal course of business, there are outstanding various commitments
and contingent liabilities which are not reflected in the consolidated financial
statements. The Company does not anticipate losses as a result of these
commitments. Undisbursed loan commitments totaled $86,523,000 and $73,724,000 at

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

10. COMMITMENTS AND CONTINGENT LIABILITIES (CONTINUED)
December 31, 1999 and 1998. Standby letters of credit were $5,541,000 and
$4,652,000 at December 31, 1999 and 1998. The Company's exposure to credit loss
is limited to amounts funded or drawn.

    Loan commitments are typically contingent upon the borrower meeting certain
financial and other covenants and such commitments typically have fixed
expiration dates and require payment of a fee. As many of these commitments are
expected to expire without being drawn upon, the total commitments do not
necessarily represent future cash requirements. The Company evaluates each
potential borrower and the necessary collateral on an individual basis.
Collateral varies, but may include real property, bank deposits or business or
personal assets.

    Standby letters of credit are conditional commitments written by the Company
to guarantee the performance of a customer to a third party. These guarantees
are issued primarily relating to inventory purchases by the Company's commercial
customers and such guarantees are typically short-term. Credit risk is similar
to that involved in extending loan commitments to customers and the Company,
accordingly, uses evaluation and collateral requirements similar to those for
loan commitments. Virtually all of such commitments are collateralized.

11. LOAN CONCENTRATIONS

    The Bank's customers are primarily located in Santa Cruz, Monterey and San
Benito counties, an area on the California coast south of San Francisco.
Commercial loans represent 16% of total loans at December 31, 1999, with no
particular industry representing a significant portion. Approximately 20% of the
Company's loans at December 31, 1999 are for real estate construction including
single family residential and commercial properties. Other real estate secured
loans, primarily for commercial properties, represent another 62% of loans at
December 31, 1999. Installment and other loans, primarily automobile and mobile
home loans, represent the remainder of loans. Many of the Company's customers
are employed by or are otherwise dependent on the tourism, high technology,
agriculture and real estate development industries and, accordingly, the ability
of any of the Company's borrowers to repay loans may be affected by the
performance of these sectors of the economy. Virtually all loans are
collateralized. Generally, real estate loans are secured by real property and
commercial and other loans are secured by bank deposits or business or personal
assets. Repayment is generally expected from refinancing or sale of the related
property for real estate construction loans and from cash flows of the borrower
for other loans.

12. RELATED PARTY LOANS

    The Bank may make loans to directors and their associates subject to
approval by the Board of Directors. These transactions are at terms and rates
comparable to those granted to other customers of the Company. Loans to related
parties were $429,000 and $223,000 at December 31, 1999 and 1998, respectively.
During 1999, new loans to these related parties were $274,000 and repayments
were $68,000.

13. REGULATORY MATTERS

    The Company and the Bank are subject to various regulatory capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can initiate certain mandatory and possibly
additional discretionary actions by regulators that, if undertaken, could have a
direct material effect on the Company's financial statements. Under capital
adequacy guidelines and the

13. REGULATORY MATTERS (CONTINUED)
regulatory framework for prompt corrective action, the Company and the Bank must
meet specific capital guidelines that involve quantitative measures of assets,
liabilities, and certain off-balance sheet items as calculated under regulatory
accounting practices. The Company's and Bank's capital amounts and
classification are also subject to qualitative judgments by the regulators about
components, risk weightings, and other factors.

    Quantitative measures established by regulation to ensure capital adequacy
require the Company and the Bank to maintain minimum amounts and ratios (set
forth in the table below) of total and Tier I capital (as defined in the
regulations) to risk weighted assets (as defined), and of Tier I capital (as
defined) to average assets (as defined). Management believes, as of
December 31, 1999, that the Company and Bank meet all capital adequacy
requirements to which they are subject.

    As of December 31, 1999 and 1998, the most recent notification from the
Federal Deposit Insurance Corporation categorized the Bank as well capitalized
under the regulatory framework for prompt corrective action. To be categorized
as adequately capitalized the Bank must maintain minimum total risk-based, Tier
I risk-based, and Tier I leverage ratios as set forth in the table. There are no
conditions or events since that notification that management believes have
changed the institution's category.

    Actual capital amounts and ratios are as follows:

14. EMPLOYEE BENEFIT PLANS

    The Company has a 401(k) tax-deferred savings plan under which eligible
employees may elect to have a portion of their salary deferred and contributed
to the plan. The Company is not obligated to, but may contribute to the plan. In
1999 and 1998, the Company matched each employee's contribution up to $1,000, an
increase from $500 in 1997, aggregating $101,000 in 1999, $90,000 in 1998 and
$42,000 in 1997. Participants may elect several investment options.

    Substantially all employees with at least 1,000 hours of service are covered
by a discretionary employee stock ownership plan (ESOP). The Company's
contribution to the ESOP was $120,000 in 1997. No contribution was made during
1999 and 1998.

    The Bank established a profit sharing plan for eligible employees during
1998. Distributions under the profit sharing plan are tied to the Bank's net
income. The Bank accrued $191,000 in 1999 and $180,000 in 1998 for profit
sharing distributions.

    The Bank has an unfunded salary continuation plan for selected officers
which provides for retirement benefits upon reaching age 62. The Bank accrues
such post-retirement benefits over the estimated service period. In the event of
termination following a change in control of the Company, the officers' benefits
will fully vest. The Bank accrued $242,000, $61,000, and $72,000 in 1999, 1998,
and 1997, respectively. The liability under the salary continuation plan was
$717,000 and $474,000 at December 31, 1999 and 1998, respectively. The discount
rate used to measure the liability was 7.00% and 7.05% at December 31, 1999 and
1998, respectively.

    The Bank has a deferred compensation plan whereby certain directors defer
their fees until age 65 or 70. Amounts deferred accrue interest at a rate
determined annually by the Board of Directors (5.9% and 6.7% for 1999 and 1998,
respectively). Accumulated benefits are paid over 8 to 13 years. Total deferred
director fees at December 31, 1999 and 1998 were $810,000 and $705,000,
respectively.

    Under the 1995 stock option plan (Plan) the Company may grant options to
purchase up to 880,000 shares of common stock to employees, directors and
consultants at prices not less than the fair market value at date of grant.
Employee options generally expire 5 to 10 years from the date of grant and vest
over a 5-year period. Under the Plan non-employee directors of the Company are
automatically granted options to purchase 4,400 shares of common stock at the
fair market value at the date of grant each year that such person remains a
director of the Company. Options granted under the Plan to non-employee
directors are exercisable after 6 months and expire 5 years from the date of

    At December 31, 1999, 475,200 shares were available for future grants under
the option plan.

    As discussed in Note 1, the Company continues to account for its stock-based
awards using the intrinsic value method in accordance with APB Opinion No. 25,
"Accounting for Stock Issued to Employees" and its related interpretations.
Accordingly, no compensation expense has been recognized in the financial
statements for employee stock arrangements.

    SFAS No. 123, "Accounting for Stock-Based Compensation," requires the
disclosure of pro forma net income and earnings per share had the Company
adopted the fair value method as of the beginning of fiscal 1995. Under
SFAS 123, the fair value of stock-based awards to employees is calculated
through the use of option pricing models, even though such models were developed
to estimate the fair value of freely tradable, fully transferable options
without vesting restrictions, which significantly differ from the Company's
stock option awards. These models also require subjective assumptions, including
future stock price volatility and expected time to exercise, which greatly
affect the calculated values. The Company's calculations were made using the
Black-Scholes option pricing model with the following weighted average

assumptions: expected life following grant, 73 months in 1999, 100 months in
1998, and 101 months in 1997; stock volatility, 50% in 1999, 1998 and 1997; risk
free interest rates, 4.98% in 1999, 5.54% in 1998, and 6.55% in 1997; and 24%
dividends during the expected term. The Company's calculations are based on a
single option valuation approach and forfeitures are recognized as they occur.
If the computed fair values of the stock option awards had been amortized to
expense over the vesting period of the awards, pro forma net income would have
been as follows:

15. DISCLOSURE OF FAIR VALUE OF FINANCIAL INSTRUMENTS

    The estimated fair value amounts have been determined by using available
market information and appropriate valuation methodologies. However,
considerable judgment is required to interpret market data to develop the
estimates of fair value. Accordingly, the estimates presented are not
necessarily indicative of the amounts that could be realized in a current market
exchange. The use of different market assumptions and/or estimation techniques
may have a material effect on the estimated fair value amounts.

    The following table presents the carrying amount and estimated fair value of
certain assets and liabilities held by the Company at December 31, 1998 and
1997. The carrying amounts reported in the consolidated balance sheets
approximate fair value for the following financial instruments: cash and due
from banks, federal funds sold, cash surrender value of life insurance and
demand and savings deposits. See Note 3 for a summary of the estimated fair
value of securities.

</TABLE>

    The following methods and assumptions were used by the Company in computing
the estimated fair values in the above table:

    LOANS, NET--The fair value of variable rate loans is the carrying value as
these loans are regularly adjusted to market rates. The fair value of fixed rate
loans is estimated by discounting the future cash flows using current rates at
which similar loans would be made to borrowers with similar credit ratings for
the same remaining maturities. The fair value calculations are adjusted by the
allowance for credit losses.

    TIME DEPOSITS--The fair value of fixed rate time deposits was estimated by
discounting the cash flows using rates currently offered for deposits of similar
remaining maturities.

    OTHER BORROWINGS--The fair value of fixed rate other borrowings was
estimated by discounting the cash flows using rates currently offered for these
types of borrowings of similar remaining maturities.

    UNUSED COMMITMENTS TO EXTEND CREDIT--The fair value of letters of credit and
standby letters of credit is not significant.

    A principal source of cash for the Company is dividends from the Bank.
Banking regulations limit the amount of dividends that may be paid without prior
approval of the Company's regulatory agencies to the lesser of retained earnings
or the net income of the Company for its last three fiscal years, less any
distributions during those years, subject to capital adequacy requirements. At
December 31, 1999, the Company has approximately $14,412,000 available for
payment of dividends which would not require the prior approval of the banking
regulators under this limitation.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of

Coast Bancorp:

    We have audited the accompanying consolidated balance sheets of Coast
Bancorp and its subsidiary as of December 31, 1999 and 1998, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Coast Bancorp and its
subsidiary as of December 31, 1999 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with generally accepted accounting principles.
