This report may contain certain forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of
the Securities Exchange Act of 1934, as amended. The Company (as defined
below) intends such forward-looking statements to be covered by the safe
harbor provisions for forward-looking statements contained in the Private
Securities Reform Act of 1995, and is including this statement for purposes
of indicating such intent. Forward-looking statements which are based on
certain assumptions and describe future plans, strategies and expectations of
the Company, are generally identifiable by use of the words "believe,"
"expect," "intend," "anticipate," "estimate," "project" or similar
expressions. The Company's ability to predict results or the actual effect of
future plans or strategies is inherently uncertain. Factors which could have
a material adverse affect on the operations and future prospects of the
Company and its subsidiaries include, but are not limited to, changes in
interest rates, general economic conditions, legislative/regulatory changes,
monetary and fiscal policies of the U.S. Government, including policies of
the U.S. Treasury and the Federal Reserve Board, the quality or composition
of their loan or investment portfolios, demand for loan products, deposit
flows, competition, demand for financial services in the Company's market
area and accounting principles, policies and guidelines. These risks and
uncertainties should be considered in evaluating forward-looking statements
and undue reliance should not be placed on such statements. Further
information concerning the Company and its business, including additional
factors that could materially affect the Company's financial results, is
included in the Company's filings with the Securities and Exchange Commission.

                                        PART I
ITEM 1.   BUSINESS

REGISTRANT AND ITS SUBSIDIARY

West Suburban Bancorp, Inc., an Illinois corporation (together with the Bank
(as defined below) and the Bank's subsidiaries, the "Company"), is a bank
holding company registered under the Bank Holding Company Act of 1956, as
amended (the "BHC Act") and the parent company of West Suburban Bank,
Lombard, Illinois. West Suburban Bank, may be referred to as the "Bank."

During the first quarter of 1997, the Bank received approvals from the
Federal Deposit Insurance Corporation, the Office of the Illinois
Commissioner of Banks and Real Estate and the Office of Thrift Supervision to
merge the four bank subsidiaries and the thrift subsidiary into one state
chartered bank under the name "West Suburban Bank." On May 17, 1997, the
Company's subsidiaries were merged and since that date, the Company has
conducted its banking activities through its single bank subsidiary. The
merger had no significant impact on the Company's financial condition or
results of operations.

The Company was incorporated in 1986 and became the parent bank holding
company of the Bank and the Company's former bank subsidiaries in 1988.
On July 13, 1990, the Company acquired its former thrift subsidiary, a
federally-chartered thrift, thereby becoming a thrift holding company until
the former thrift was merged into the Bank in 1997.

The Bank is headquartered in the western suburbs of Chicago among some of the
faster growing areas in Illinois. Due to the nature of the market areas
served by the Bank, the Bank provides a wide range of financial services to
individuals and small and medium sized businesses. The western suburbs of
Chicago have a diversified economy, with many new corporate headquarters and
numerous small and medium sized industrial and non-industrial businesses
providing employment.

                                       4

The Bank engages in a general full service retail banking business and offers
a broad variety of consumer and commercial products and services. The Bank
also offers trust services, safe deposit boxes and extended banking hours,
including Sunday hours and 24-hour banking through either a proprietary
network of 36 automated teller machines ("ATMs") or Tele-Bank 24, a
bank-by-phone system. Other consumer related services are available including
financial services and a competitively priced VISA card through West Suburban
Bank Card Services. The Bank offers its customers a debit card called the
West Suburban Bank Check Card.

COMPETITION

The Company encounters competition in all areas of its business pursuits. It
competes for loans, deposits, fiduciary and other services with financial and
other institutions located both within and outside of its market area. In
order to compete effectively, to develop its market base, to maintain
flexibility and to move in pace with changing economic and social conditions,
the Company continuously refines and develops its products and services. The
principal methods of competition in the financial services industry are
price, service and convenience.

EMPLOYEES

The Company employed 590 persons (460 full time equivalent employees) on
December 31, 1997. The Company believes that its relations with its employees
are good.

SUPERVISION AND REGULATION

General

Financial institutions and their holding companies are extensively regulated
under federal and state law.  As a result, the growth and earnings
performance of the Company can be affected not only by management decisions
and general economic conditions, but also by the requirements of applicable
state and federal statutes and regulations and the policies of various
governmental regulatory authorities including, but not limited to, the Board
of Governors of the Federal Reserve System (the "FRB"), the Federal Deposit
Insurance Corporation (the "FDIC"), the Illinois Commissioner of Banks and
Real Estate (the "Commissioner"), the Internal Revenue Service and state
taxing authorities and the Securities and Exchange Commission (the "SEC").
The effect of such statutes, regulations and policies can be significant, and
cannot be predicted with a high degree of certainty.

Federal and state laws and regulations generally applicable to financial
institutions, such as the Company and its subsidiary, regulate, among other
things, the scope of business, investments, reserves against deposits,
capital levels relative to operations, the nature and amount of collateral
for loans, the establishment of branches, mergers, consolidations and
dividends. The system of supervision and regulation applicable to the Company
and its subsidiaries establishes a comprehensive framework for their
respective operations and is intended primarily for the protection of the
FDIC's deposit insurance funds and the depositors, rather than the
shareholders, of financial institutions.

The following references to material statutes and regulations affecting the
Company and its subsidiaries are brief summaries thereof and do not purport
to be complete, and are qualified in their entirety by reference to such
statutes and regulations.  Any change in applicable law or regulations may
have a material effect on the business of the Company and its subsidiaries.

Recent Regulatory Developments

PENDING LEGISLATION.  Legislation is pending in the Congress that would allow
bank holding companies to engage in a wider range of nonbanking activities,
including greater authority to engage in securities and insurance activities.
The expanded powers generally would be available to a bank holding company
only if the bank holding company and its bank subsidiaries remain
well-capitalized and well-managed.  Additionally, the pending legislation
would eliminate the federal thrift charter and merge the FDIC's Bank
Insurance Fund ("BIF") and Savings Association Insurance Fund ("SAIF").  At
this time, the Company is unable to predict whether the proposed legislation
will be enacted and, therefore, is unable to predict the impact such
legislation may have on the operations of the Company and the Bank.

The Company

GENERAL. The Company, as the sole stockholder of the Bank, is a bank holding
company.  As a bank holding company, the Company is registered with, and is
subject to regulation by, the FRB under the BHCA.  In accordance with FRB
policy, the Company is expected to act as a source of financial strength to
the Bank and to commit resources to support the Bank in circumstances where
the Company might not do so absent such policy.  Under the BHCA, the Company
is subject to periodic examination by the FRB and is required to file with
the FRB periodic reports of its operations and such additional information as
the FRB may require. The Company is also subject to regulation by the
Commissioner under the Illinois Bank Holding Company Act, as amended.

INVESTMENTS AND ACTIVITIES. Under the BHCA, a bank holding company must
obtain FRB approval before:  (i) acquiring, directly or indirectly, ownership
or control of any voting shares of another bank or bank holding company if,
after such acquisition, it would own or control more than 5% of such shares
(unless it already owns or controls the majority of such shares); (ii)
acquiring all or substantially all of the assets of another bank; or (iii)
merging or consolidating with another bank holding company.

                                       7
<PAGE>

Subject to certain conditions (including certain deposit concentration limits
established by the BHCA), the FRB may allow a bank holding company to acquire
banks located in any state of the United States without regard to whether the
acquisition is prohibited by the law of the state in which the target bank is
located.  In approving interstate acquisitions, however, the FRB is required
to give effect to applicable state law limitations on the aggregate amount of
deposits that may be held by the acquiring bank holding company and its
insured depository institution affiliates in the state in which the target
bank is located (provided that those limits do not discriminate against
out-of-state depository institutions or their holding companies) or which
require that the target bank have been in existence for a minimum period of
time (not to exceed five years) before being acquired by an out-of-state bank
holding company.

The BHCA also prohibits, with certain exceptions, the Company from acquiring
direct or indirect ownership or control of more than 5% of the voting shares
of any company which is not a bank and from engaging in any business other
than that of banking, managing and controlling banks or furnishing services
to banks and their subsidiaries.  The principal exception to this prohibition
allows bank holding companies to engage in, and to own shares of companies
engaged in, certain businesses found by the FRB to be "so closely related to
banking ... as to be a proper incident thereto."  Under current regulations
of the FRB, the Company and its non-bank subsidiaries are permitted to engage
in, among other activities, such banking-related businesses as the operation
of a thrift, sales and consumer finance, equipment leasing, the operation of
a computer service bureau, including software development, and mortgage
banking and brokerage.  The BHCA generally does not place territorial
restrictions on the domestic activities of non-bank subsidiaries of bank
holding companies.

Federal law also prohibits acquisition of "control" of a bank, such as the
Bank, or bank holding company, such as the Company, without prior notice to
certain federal bank regulators.  "Control" is defined in certain cases as
the acquisition of 10% of the outstanding shares of a bank or bank holding
company.

CAPITAL REQUIREMENTS.   Bank holding companies are required to maintain
minimum levels of capital in accordance with FRB capital adequacy guidelines.
If capital falls below minimum guideline levels, a bank holding company,
among other things, may be denied approval to acquire or establish additional
banks or non-bank businesses.

The FRB's capital guidelines establish the following minimum regulatory
capital requirements for bank holding companies:  a risk-based requirement
expressed as a percentage of total risk-weighted assets, and a leverage
requirement expressed as a percentage of total assets.  The risk-based
requirement consists of a minimum ratio of total capital to total
risk-weighted assets of 8%, at least one-half of which must be Tier I
capital.  The leverage requirement consists of a minimum ratio of Tier I
capital to total assets of 3% for the most highly rated companies, with
minimum requirements of 4% to 5% for all others.  For purposes of these
capital standards, Tier I capital consists primarily of permanent
stockholders' equity less intangible assets (other than certain mortgage
servicing rights and purchased credit card relationships) and total capital
means Tier I capital plus certain other debt and equity instruments which do
not qualify as Tier I capital and a portion of the Company's allowance for
loan and lease losses.

The risk-based and leverage standards described above are minimum
requirements, and higher capital levels will be required if warranted by the
particular circumstances or risk profiles of individual banking
organizations. For example, the FRB's capital guidelines contemplate that
additional capital may be required to take adequate account of, among other
things, interest rate risk, or the risks posed by concentrations of credit,
nontraditional activities or securities trading activities.  Further, any
banking organization experiencing or anticipating significant growth would be
expected to maintain capital ratios, including tangible capital positions
(I.E., Tier I capital less all intangible assets), well above the minimum
levels.

                                       8
<PAGE>

As of December 31, 1997, the Company had regulatory capital in excess of the
FRB's minimum requirements, with a risk-based capital ratio of 13.7% and a
leverage ratio of 10.2%.

DIVIDENDS. The FRB has issued a policy statement with regard to the payment
of cash dividends by bank holding companies.  In the policy statement, the
FRB expressed its view that a bank holding company should not pay cash
dividends which exceed its net income or which can only be funded in ways
that weaken the bank holding company's financial health, such as by
borrowing.  Additionally, the FRB possesses enforcement powers over bank
holding companies and their non-bank subsidiaries to prevent or remedy
actions that represent unsafe or unsound practices or violations of
applicable statutes and regulations.  Among these powers is the ability to
proscribe the payment of dividends by banks and bank holding companies.

In addition to the restrictions on dividends that may be imposed by the FRB,
the Illinois Business Corporation Act, as amended, prohibits the Company from
paying a dividend if, after giving effect to the dividend, the Company would
be insolvent or the net assets of the Company would be less than zero or less
than the maximum amount then payable to shareholders of the Company who would
have preferential distribution rights if the Company were liquidated.

The Bank

GENERAL.  The Bank is an Illinois-chartered bank, the deposit accounts of
which are insured by the BIF of the FDIC.  As a BIF-insured,
Illinois-chartered bank, the Bank is subject to the examination, supervision,
reporting and enforcement requirements of the Commissioner, as the chartering
authority for Illinois banks, and the FDIC, as administrator of the BIF.

DEPOSIT INSURANCE.  As an FDIC-insured institution, the Bank is required to
pay deposit insurance premium assessments to the FDIC.  The FDIC has adopted
a risk-based assessment system under which all insured depository
institutions are placed into one of nine categories and assessed insurance
premiums based upon their respective levels of capital and results of
supervisory evaluations. Institutions classified as well-capitalized (as
defined by the FDIC) and considered healthy pay the lowest premium while
institutions that are less than adequately capitalized (as defined by the
FDIC) and considered of substantial supervisory concern pay the highest
premium.  Risk classification of all insured institutions is made by the FDIC
for each semi-annual assessment period.

During the year ended December 31, 1997, BIF assessments ranged from 0% of
deposits to 0.27% of deposits.  For the semi-annual assessment period
beginning January 1, 1998, BIF assessment rates will continue to range from
0% of deposits to 0.27% of deposits.

The FDIC may terminate the deposit insurance of any insured depository
institution if the FDIC determines, after a hearing, that the institution has
engaged or is engaging in unsafe or unsound practices, is in an unsafe or
unsound condition to continue operations or has violated any applicable law,
regulation, order, or any condition imposed in writing by, or written
agreement with, the FDIC.  The FDIC may also suspend deposit insurance
temporarily during the hearing process for a permanent termination of
insurance if the institution has no tangible capital.  Management of the
Company is not aware of any activity or condition that could result in
termination of the deposit insurance of the Bank.

FICO ASSESSMENTS.  Since 1987, a portion of the deposit insurance assessments
paid by SAIF members has been used to cover interest payments due on the
outstanding obligations of the FICO, the entity created to finance the
recapitalization of the Federal Savings and Loan Insurance Corporation, the
SAIF's predecessor insurance fund.  Pursuant to federal legislation enacted
September 30, 1996, commencing January 1, 1997, both SAIF members and BIF
members became subject to assessments to cover the interest payments on
outstanding FICO obligations.  Such FICO assessments are in addition to
amounts assessed by the FDIC for deposit insurance.  Until January 1, 2000,
the FICO assessments

                                       9
<PAGE>

made against BIF members may not exceed 20% of the amount of the FICO
assessments made against SAIF members.  Between January 1, 2000, and the
maturity of the outstanding FICO obligations in 2019, BIF members and SAIF
members will share the cost of the interest on the FICO bonds on a PRO RATA
basis.  During the year ended December 31, 1997, the FICO assessment rate for
SAIF members was approximately 0.063% of deposits while the FICO assessment
rate for BIF members was approximately 0.013% of deposits.  During the year
ended December 31, 1997, the Bank paid FICO assessments totaling $.17 million.

COMMISSIONER ASSESSMENTS.  All Illinois banks are required to pay supervisory
fees to the Commissioner to fund the operations of the Commissioner.  The
amount of such supervisory fees is based upon each institution's total
assets, including consolidated subsidiaries, as reported to the Commissioner.
During the year ended December 31, 1997, the Bank paid supervisory fees to
the Commissioner totaling $.13 million.

CAPITAL REQUIREMENTS. The FDIC has established the following minimum capital
standards for state-chartered insured non-member banks, such as the Bank:  a
leverage requirement consisting of a minimum ratio of Tier I capital to total
assets of 3% for the most highly-rated banks with minimum requirements of 4%
to 5% for all others, and a risk-based capital requirement consisting of a
minimum ratio of total capital to total risk-weighted assets of 8%, at least
one-half of which must be Tier I capital. For purposes of these capital
standards, Tier I capital and total capital consist of substantially the same
components as Tier I capital and total capital under the FRB's capital
guidelines for bank holding companies (SEE "--The Company--Capital
Requirements").

The capital requirements described above are minimum requirements.  Higher
capital levels will be required if warranted by the particular circumstances
or risk profiles of individual institutions.  For example, the regulations of
the FDIC provide that additional capital may be required to take adequate
account of, among other things, interest rate risk or the risks posed by
concentrations of credit, nontraditional activities or securities trading
activities.

During the year ended December 31, 1997, the Bank was not required by the
FDIC to increase its capital to an amount in excess of the minimum regulatory
requirements.  As of December 31, 1997, the Bank exceeded its minimum
regulatory capital requirements with a leverage ratio of 8.3% and a
risk-based capital ratio of 11.6%.

Federal law provides the federal banking regulators with broad power to take
prompt corrective action to resolve the problems of undercapitalized
institutions.  The extent of the regulators' powers depends on whether the
institution in question is "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" or "critically
undercapitalized."  Depending upon the capital category to which an
institution is assigned, the regulators' corrective powers include:
requiring the submission of a capital restoration plan; placing limits on
asset growth and restrictions on activities; requiring the institution to
issue additional capital stock (including additional voting stock) or to be
acquired; restricting transactions with affiliates; restricting the interest
rate the institution may pay on deposits; ordering a new election of
directors of the institution; requiring that senior executive officers or
directors be dismissed; prohibiting the institution from accepting deposits
from correspondent banks; requiring the institution to divest certain
subsidiaries; prohibiting the payment of principal or interest on
subordinated debt; and ultimately, appointing a receiver for the institution.

DIVIDENDS.  Under the Illinois Banking Act, Illinois-chartered banks may not
pay dividends in excess of their adjusted profits.

The payment of dividends by any financial institution or its holding company
is affected by the requirement to maintain adequate capital pursuant to
applicable capital adequacy guidelines and regulations, and a financial
institution generally is prohibited from paying any dividends if, following
payment thereof, the institution would be undercapitalized.  As described
above, the Bank exceeded its minimum capital requirements under applicable
guidelines as of December 31, 1997.  As of

                                       10
<PAGE>

December 31, 1997, approximately $16.1 million was available to be paid as
dividends to the Company by the Bank.  Notwithstanding the availability of
funds for dividends, however, the FDIC may prohibit the payment of any
dividends by the Bank if the FDIC determines such payment would constitute an
unsafe or unsound practice.

INSIDER TRANSACTIONS.  The Bank is subject to certain restrictions imposed by
the Federal Reserve Act on extensions of credit to the Company and its
subsidiaries, on investments in the stock or other securities of the Company and
its subsidiaries and the acceptance of the stock or other securities of the
Company or its subsidiaries as collateral for loans.  Certain limitations and
reporting requirements are also placed on extensions of credit by the Bank to
its directors and officers, to directors and officers of the Company and its
subsidiaries, to principal stockholders of the Company, and to "related
interests" of such directors, officers and principal stockholders.  In addition,
federal law and regulations may affect the terms upon which any person becoming
a director or officer of the Company or one of its subsidiaries or a principal
stockholder of the Company may obtain credit from banks with which the Bank
maintains a correspondent relationship.

SAFETY AND SOUNDNESS STANDARDS.  The federal banking agencies have adopted
guidelines which establish operational and managerial standards to promote the
safety and soundness of federally insured depository institutions.  The
guidelines set forth standards for internal controls, information systems,
internal audit systems, loan documentation, credit underwriting, interest rate
exposure, asset growth, compensation, fees and benefits, asset quality and
earnings.  In general, the guidelines prescribe the goals to be achieved in each
area, and each institution is responsible for establishing its own procedures to
achieve those goals.  If an institution fails to comply with any of the
standards set forth in the guidelines, the institution's primary federal
regulator may require the institution to submit a plan for achieving and
maintaining compliance.  The preamble to the guidelines states that the agencies
expect to require a compliance plan from an institution whose failure to meet
one or more of the guidelines is of such severity that it could threaten the
safety and soundness of the institution.  Failure to submit an acceptable plan,
or failure to comply with a plan that has been accepted by the appropriate
federal regulator, would constitute grounds for further enforcement action.

BRANCHING AUTHORITY.  Illinois banks, such as the Bank, have the authority under
Illinois law to establish branches anywhere in the State of Illinois, subject to
receipt of all required regulatory approvals.

Effective June 1, 1997 (or earlier if expressly authorized by applicable
state law), the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Riegle-Neal Act") allows banks to establish interstate branch
networks through acquisitions of other banks, subject to certain conditions,
including certain limitations on the aggregate amount of deposits that may be
held by the surviving bank and all of its insured depository institution
affiliates.  The establishment of DE NOVO interstate branches or the
acquisition of individual branches of a bank in another state (rather than
the acquisition of an out-of-state bank in its entirety) is allowed by the
Riegle-Neal Act only if specifically authorized by state law.  The
legislation allows individual states to "opt-out" of certain provisions of
the Riegle-Neal Act by enacting appropriate legislation prior to June 1,
1997.  Illinois has enacted legislation permitting interstate mergers
beginning on June 1, 1997, subject to certain conditions, including a
prohibition against interstate mergers unless any Illinois bank involved has
been in existence and continuous operation for more than five years.

STATE BANK ACTIVITIES.  Under federal law and FDIC regulations, FDIC insured
state banks are prohibited, subject to certain exceptions, from making or
retaining equity investments of a type, or in an amount, that are not
permissible for a national bank.  Federal law and FDIC regulations also prohibit
FDIC insured state banks and their subsidiaries, subject to certain exceptions,
from engaging as principal in any activity that is not permitted for a national
bank or its subsidiary, respectively, unless the bank meets, and continues to
meet, its minimum regulatory capital requirements and the FDIC determines the
activity would not pose a significant risk to the deposit insurance fund of
which the bank is a member.  Impermissible investments and activities must be
divested or discontinued within certain time

                                      11
<PAGE>

frames set by the FDIC.  These restrictions have not had, and are not
currently expected to have, a material impact on the operations of the Bank.

FEDERAL RESERVE SYSTEM.  FRB regulations, as presently in effect, require
depository institutions to maintain non-interest earning reserves against
their transaction account balances (primarily NOW and regular checking
accounts), as follows: for transaction account balances aggregating $47.8
million or less, the reserve requirement is 3% of total transaction account
balances; and for transaction account balances aggregating in excess of $47.8
million, the reserve requirement is $1.4 million plus 10% of the aggregate
amount of total transaction account balances in excess of $47.8 million.  The
first $4.7 million of otherwise reservable balances are exempted from the
reserve requirements.  These reserve requirements are subject to annual
adjustment by the FRB.  The Bank is in compliance with the foregoing
requirements.

INSURANCE SUBSIDIARY.  The Bank is the sole shareholder of West Suburban
Insurance Services, Inc. ("WSIS"), an Illinois corporation licensed as a general
insurance agency by the Illinois Department of Insurance (the "Department").
WSIS is subject to supervision and regulation by the Department with regard to
compliance with the laws and regulations governing insurance agents and by the
Commissioner and the FDIC with regard to compliance with the banking laws and
regulations applicable to subsidiaries of Illinois-chartered, FDIC-insured
banks.

At December 31, 1997, the Company had $20.1 million outstanding in loans, leases
and debt securities (the "Instruments") represented by or secured by leases
originated by one customer of the Company.  Collectibility of the Instruments
is primarily dependent on the collection of the payments required to be made
under the underlying leases.  All Instruments were current as to principal and
interest at December 31, 1997.

The Company's policy is to discontinue accruing interest on a loan when it
becomes 90 days past due or when management believes, after considering economic
and business conditions and collection efforts, that the borrower's financial
condition is such that collection of principal or interest is doubtful. In some
circumstances a loan that is more than 90 days past due can remain on accrual
status if it can be established that payment will be received within another 90
days or if it is fully secured and in process of collection. When a loan has
been placed on nonaccrual status, interest that has been earned but not
collected is charged back to the appropriate interest income account. When
payments are received on nonaccrual loans they are first applied to principal,
then to expenses incurred for collection and finally to interest income. The
gross amount of interest that would have been recorded if all nonaccruing loans
had been accruing interest at their original terms was approximately $321 for
the year ended December 31, 1997 and no interest on nonaccruing loans was
recorded in operations for the year ended December 31, 1997.

The Company's impaired loans consisted of commercial and non-residential
mortgage loans totaling $17,156 at December 31, 1997 and $17,755 at December 31,
1996. Of these impaired loans, $2,496 required a valuation allowance of $676 at
December 31, 1997 compared to impaired loans of $1,422 with a valuation
allowance of $182 at December 31, 1996. The average outstanding balance of
impaired loans was approximately $15,718 and $17,389 for the years ended
December 31, 1997 and 1996, respectively. The interest income recognized on
impaired loans was approximately $1,783 and $1,706 for the years ended December
31, 1997 and 1996, respectively. The Company had no impaired real estate
construction loans during 1997 or 1996.

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses
charged to expense. Loans are charged against the allowance for loan losses when
management believes that the collectibility of the principal is unlikely. The
allowance is an amount that management believes will be adequate to absorb
losses on existing loans that may become uncollectible, based on evaluations of
the collectibility of loans and prior loan loss experience. The evaluations take
into consideration such factors as changes in the nature and volume of the loan
portfolio, overall portfolio quality, review of specific problem loans and
current economic conditions that may affect the borrowers' ability to pay.

The Company reviews its commercial and real estate construction and
non-residential mortgage loans on a quarterly basis to determine the amount of
impairment, if any. Impairment is measured based on the present value of
expected future cash flows discounted at the loan's effective interest rate, the
loan's observable market price, or the fair value of the loan's collateral, if
repayment of the loan is collateral dependent. A valuation allowance is
maintained for the amount of impairment. Generally, loans 90 or more days past
due and all loans on a nonaccrual basis are considered impaired. Interest income
on impaired loans is recognized in a manner consistent with the Company's
interest policy.  Based on such reviews, management at this time does not
anticipate any increase in nonperforming assets that will have a significant
affect on its operations because the estimated exposure to losses has already
been substantially reflected in its allowance for loan losses.  This could,
however, change dramatically if a significant decline in the real estate market
area served by the Company occurs.

The following table sets forth the activity in the allowance for loan losses for
the years ended and at December 31 (dollars in thousands):
