ITEM 1.  BUSINESS

General
- -------

First Oak Brook Bancshares, Inc. ("the Company") was organized under Delaware
law on March 3, 1983, as a bank holding company under the Bank Holding Company
Act of 1956, as amended.  The Company owns all of the outstanding capital stock
of Oak Brook Bank ("the Bank"), Oak Brook, Illinois, which is an Illinois state-
chartered bank.  The bank has eight locations in DuPage County and two locations
in Cook County.  A new branch opened in Aurora, Illinois in January, 1998 and
one is scheduled to open in Glen Ellyn, Illinois in the fourth quarter of 1998;
both are located in DuPage County.

The Company has two classes of common stock, Class A Common stock and Common
stock.  The Common stock is convertible into Class A Common at any time on a
one-for-one basis.  The Company has authorized shares of Class A Common and
Common stock of 4,000,000 and 3,000,000, respectively.

As of December 31, 1997, the Company had total assets of $816,144,000; loans of
$447,332,000, deposits of $627,763,000, and shareholders' equity of $71,661,000.

The business of the Company consists primarily of the ownership, supervision and
control of its subsidiary bank.  The Company provides its subsidiary bank with
advice, counsel and specialized services in various fields of banking policy and
strategic planning.  The Company also engages in negotiations designed to lead
to the acquisition of other banks and closely related businesses.

The Bank is engaged in the general retail and commercial banking business.  The
services offered include demand, savings, and time deposits, corporate cash
management services, and commercial and personal lending products.  In addition,
related products and services are offered including discount brokerage, mutual
funds and annuity sales and foreign currency sales.  The Bank has a full service
investment management and trust department.

The Bank originates the following types of loans: commercial, real estate (land
acquisition and construction, commercial mortgages, residential mortgages and
home equity lines), indirect auto and consumer loans.  The extension of credit
inherently involves certain levels and types of risk (general economic
conditions, industry and concentration risk, interest rate risk, and credit and
default risk) which the Company manages through the establishment of lending,
credit and asset/liability management policies and procedures.

On June 30, 1997, the Company sold substantially all of its credit card
portfolio.  Although credit card lending was still a

                                       2
<PAGE>
 
high-return business, future growth potential was questionable, acquiring and
retaining customers was becoming more difficult and more costly, and consumer
delinquency and bankruptcy was increasing.  The sale allows the Company to
market credit cards under an agency relationship and refocus internal efforts on
the acquiring (merchant) side of the business and strengthen other of the Bank's
core businesses.

Loans originated comply with the Bank's loan policies and governmental rules,
regulations and laws.  While the subsidiary bank's loan policy varies for
different loan products, the policy generally covers such items as: percentages
to be advanced against collateral, blanket or specific liens, insurance
requirements, maximum terms, down payment requirements, debt-to-income ratio,
credit history and other matters of credit concern.

The Bank's loan policy grants limited loan approval authority to designated loan
officers.  Where a credit request exceeds the loan officer's approval authority,
approval by a senior lending officer and/or bank loan committee is required.
The loan policy also sets forth those credit requests that, either because of
the amount and/or type, require the approval of the bank loan committee.

The chart that follows sets forth the credit risks, loan origination procedures,
underwriting standards and lien position generally associated with the Bank's
lending in each major loan category.  The major loan categories are commercial
loans; commercial real estate, including land acquisition, development and
construction loans; residential real estate, including purchase money, refinance
and home equity loans; indirect auto loans; and consumer loans, including direct
auto loans, check credit and student loans.  These loans are made generally in
the Chicago Metropolitan area and are generally secured by collateral located in
the Chicago Metropolitan area.

The chart sets forth the information generally considered in approving each
category of loans.  The collateral stated for each category is the collateral
generally required for these loans.  Each loan is reviewed on its own merits and
the information set forth in the chart does not necessarily apply to each loan
within a category.  The lien position (if any) and collateral documentation for
commercial loans, commercial real estate and construction loans are structured
specifically for each loan.

Securities Laws and Delaware Law.  The BHCA requires every bank holding company
to obtain the prior approval of the Federal Reserve Board before acquiring
direct or indirect ownership or control of 5% or more of the voting shares of
any bank or bank holding company.  However, no acquisition may be approved if it
is prohibited by applicable state law.  The Company is examined by the Federal
Reserve Bank of Chicago.

The subsidiary bank is subject to extensive governmental regulation and periodic
regulatory reporting requirements.  The regulations by various governmental
entities, as well as Federal and State laws of general application affect the
Company and the subsidiary bank in many ways including but not limited to:
requirements to maintain reserves against deposits, payment of FDIC insurance,
restrictions on investments, establishment of lending limits and payment of
dividends.  The subsidiary bank is primarily supervised and examined by the
Illinois Office of Banks and Real Estate and the Federal Deposit Insurance
Corporation ("FDIC").

The Federal Reserve Bank examines and supervises bank holding companies pursuant
to risk-based capital adequacy guidelines.  These guidelines establish a uniform
capital framework that is

                                       7
<PAGE>
 
sensitive to risk factors, including off-balance sheet exposures, for all
federally supervised banking organizations.  This can impact a bank holding
company's ability to pay dividends and expand its business through the
acquisition of subsidiaries if capital falls below the levels established by
these guidelines.  As of December 31, 1997 the Company's Tier 1, total risk-
based capital and leveraged ratios were in excess of minimum regulatory
guidelines and also exceed the FDIC criteria for "well capitalized" banks.  See
the Company's Annual Report at pages 35-36 for a more detailed discussion of the
Risk Based Assessment System and the impact upon the Company and its subsidiary
bank.

Federal Deposit Insurance
- -------------------------

Under Federal law, the FDIC has authority to impose special assessments on
insured depository institutions, to repay FDIC borrowings from the United States
Treasury or other sources, and to establish semi-annual assessment rates for
Bank Insurance Fund ("BIF") member banks to maintain the BIF at the designated
reserve ratio required by law.  Effective January 1, 1998 the FDIC Assessment
Rate Schedule for BIF members ranged from zero for "well capitalized"
institutions to $.27 per $100 for "undercapitalized" institutions as set forth
in the following table:

     Under capitalized           17         24         27
</TABLE>

The Funds Act also authorized the Financing Corporation ("FICO") to levy annual
assessments of BIF-assessable deposits to service FICO bond obligations.  On
January 2, 1998 the Company's subsidiary bank was assessed $38,400 for its
semiannual FICO payment.  The BIF assessment must equal 1/5 of the FICO
assessment rate that is applied to deposits assessable by the Savings
Association Insurance Fund ("SAIF").  The annual assessment rates for FICO were
determined from the September 30, 1997 call reports and for BIF institutions the
rate was 1.256c per $100.

The subsidiary bank is not restricted by the limitations on Brokered Deposits
and can pass-through the $100,000 FDIC insurance coverage to each participant in
or beneficiary of a qualified employee benefit plan.

The Riegle/Neal Interstate Banking and Branching Efficiency Act of 1994 ("The
- -----------------------------------------------------------------------------
Interstate Banking Act")
- ------------------------

The Interstate Banking Act allowed "adequately capitalized" and "adequately
managed" bank holding companies to acquire banks in any state as of September
29, 1995.  The Act also allows interstate merger transactions.

The Interstate Banking Act amends Section (d) of the Bank Holding Company Act of
1956 authorizing the Federal Reserve to approve a bank holding company's
application to acquire either control or substantial assets of a bank located
outside of the bank holding company's home state regardless of whether the
acquisition would be prohibited by state law.  The Federal Reserve may approve
these transactions only for "adequately capitalized" and "adequately managed"
bank holding companies.

The Interstate Banking Act also amended the Federal Deposit Insurance Act to
allow responsible agencies to approve merger transactions between insured banks
with different home states regardless of whether the transaction is prohibited
under state law.  Through interstate merger transactions, banks are able to
acquire branches of out of state banks by converting their offices into branches
of the resulting bank.  The Act provides that it will be the exclusive means for
bank holding companies to obtain interstate branches.  In these transactions,
the resulting bank must remain "adequately capitalized" and "adequately managed"
upon completion of the merger.  The Act also states that a home state may enact
a law preventing these transactions; Illinois allows these transactions.

Financial Institutions Reform, Recovery and Enforcement Act of 1989 ("FIRREA")
- ------------------------------------------------------------------------------

The FIRREA has broadened the regulatory powers of federal bank regulatory
agencies.  One of the provisions of FIRREA contains a "cross-guarantee"
provision which could impose liability on the Company for losses incurred by the
FDIC in connection with assistance provided to or the failure of any of the
Company's insured depository institutions.  The U.S. Court of Appeals Second
Circuit recently upheld the FDIC's power to charge losses from a bank failure to
another bank in the same corporate organization.  The Company, under Federal
Reserve Board policy, is a source of financial strength to its subsidiary bank
and is expected to commit resources to support the subsidiary bank.  As a
result, the Company could be required to commit resources to its subsidiary bank
in circumstances where it might not do so absent such policies.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
- ----------------------------------------------------------------------------

The FDICIA significantly expanded the regulatory and enforcement powers of
federal banking regulators.  FDICIA gives federal banking regulators
comprehensive directions to promptly direct or require the correction of
problems of inadequately capitalized banks in a manner that is least costly to
the Federal Deposit

                                       9
<PAGE>
 
Insurance Fund. The degree of corrective regulatory involvement in the
operations and management of banks and their holding companies will be largely
determined by the actual or anticipated capital position of the institution. See
the Company's Annual Report page 21 and pages 35-36 detailing the Company's
capital position.

FDICIA also directs federal banking regulatory agencies to issue new safety and
soundness standards governing operational and managerial activities of banks and
their holding companies particularly in regard to internal controls, loan
documentation, credit underwriting, interest rate exposure, asset growth,
executive compensation and market risk sensitivity.

Year 2000
- ---------

The Federal Reserve Year 2000 Bank Supervision Program addresses how existing
application software programs and operating systems can accommodate the date
value for the Year 2000. Many computer programs were designed and developed
without considering the impact of the upcoming change of the century and
therefore many computer applications may interpret 00 as meaning 1900. The
Federal Financial Institutions Examination Counsel has issued Interagency
Statements alerting financial institutions to this problem and is requiring that
the computer systems be compliant.

The Federal Reserve has announced the following actions under its Year 2000 bank
supervision program: (1) The use of a three tiered interagency supervisory
rating system (satisfactory/needs improvement/unsatisfactory) to evaluate the
quality of the banking organization's Year 2000 compliance program and (2) The
issuance of a Year 2000 deficiency notification letter for banks rated "needs
improvement" or "unsatisfactory." The consequences of these ratings are: (i) The
Bank must prepare and submit a written acceptance in compliance with the
Interagency Statements and related FFIEC advisories; (ii) Submission of monthly
progress reports which must include actions taken; (iii) The Bank may be subject
to formal enforcement action; and (iv) Prior to any acquisition, merger or
expansion of activity, regulatory approval will be required.

Other Laws and Regulations
- --------------------------

Proposals that change the laws and regulations governing banks, bank holding
companies and other financial institutions are discussed in Congress, the state
legislatures and before the various bank regulatory agencies.  Banks are subject
to a number of federal and state laws and regulations which have a material
impact on their business.  These include, among others, state usury laws,
consumer protection laws and regulations, (e.g., the Truth in Lending Act, the
Equal Credit Opportunity Act, the Expedited Funds Availability Act, the
Community Reinvestment Act, the Truth in Savings Act), as well as the electronic
funds transfer laws, Bank Secrecy Act, environmental laws and privacy laws.

                     EXECUTIVE DEFERRED COMPENSATION PLAN

                                 INTRODUCTION
                                        

1.1  Adoption and Name of Plan.

     The Company adopts the First Oak Brook Bancshares, Inc., Executive Deferred
     Compensation Plan.

1.2  Purposes of Plan.

     The purposes of the Plan are to provide deferred compensation for a select
     group of management or highly compensated Employees of the Employer and to
     provide eligible Employees the opportunity to maximize their elective
     contributions to the Employees' Savings Plan notwithstanding certain
     restrictions and limitations in the Code.

1.3  "Top Hat" Pension Benefit Plan.

     The Plan is an "employee pension benefit plan" within the meaning of ERISA
     Section 3(2).  The Plan is maintained, however, for a select group of
     management or highly compensated employees and, therefore, is exempt from
     Parts 2, 3 and 4 of Title 1 of ERISA.  The Plan is not intended to qualify
     under Code Section 401(a).

1.4  Plan Unfunded.

     The Employer is fully committed to paying the benefits promised under this
     Plan, and recognizes that the Plan represents a binding contract; however,
     the Plan is intended to be unfunded for tax purposes, and for purposes of
     Title I of ERISA.  Participants (and, where applicable, their
     Beneficiaries) have the status of general unsecured creditors of the
     Employer, and this Plan constitutes a mere promise by the Employer to pay
     benefits in the future.  Notwithstanding the foregoing, the Employer may
     establish a "grantor trust" in which to hold cash or other assets to be
     used to make payments of Plan benefits to Participants and Beneficiaries;
     however, the assets of any such trust will at all times remain subject to
     the claims of general creditors of the Employer, in case the Employer
     becomes insolvent.  The Employer will remain liable to pay benefits under
     the Plan, although any payment of benefits made by the trust will satisfy
     the Employer's obligation to make that payment to a Participant or
     Beneficiary.

                                       1

1.5  Effective Date.

     The Plan is effective as of the Effective Date.

1.6  Administration.

     The Plan will be administered by the Committee.

                    least 15 years of service (as defined in the Employees'
                    Savings Plan for  purposes of benefit distribution), or

               (C)  with the Committee's consent; or

          (ii) qualifies for disability under the Employer's group long-term
               disability plan.

     Wherever appropriate herein, the singular includes the plural, the
     plural includes the singular, and the masculine includes the feminine.

2.3  Headings.

     The headings of Articles and Sections herein are included solely for
     convenience, and if there is any conflict between them and the rest of the
     Plan, the text will control.

3.1  Participation.

     Participants in the Plan are those individuals who are members of a select
     group of highly compensated or management Employees of the Company and
     selected by the Committee, in its sole discretion, to be Participants. The
     Committee will notify each Participant of his selection as a Participant.
     Subject to the provisions of Section 3.3, a Participant will remain
     eligible to continue participation in the Plan for each Plan Year following
     his initial year of participation in the Plan.

3.2  Commencement of Participation.

     Except as provided in the following sentence, an Employee will become a
     Participant effective as of the first day of the Plan Year following the
     date on which his Participation Agreement becomes effective. A newly
     eligible Employee (because of hire or selection by the Committee) who
     completes a Participation Agreement within thirty days after the date his
     employment commences or selection becomes effective will become a
     Participant as of the date on which his Participation Agreement is
     effective under Section 4.2.

3.3  Cessation of Active Participation.

     Notwithstanding any provision herein to the contrary, an individual who has
     become a Participant in the Plan will cease to be a Participant effective
     as of any date designated by the Committee.

4.1  Participants' Pre-tax Contributions.

     Before the first day of each Plan Year, a Participant may file with the
     Committee a Participation Agreement on which he elects to make Pre-tax
     Contributions. Participants may defer up to 10% of their Compensation. All
     Pre-tax Contribution elections must be in whole percentages. Any Pre-tax
     Contribution election will be subject to rules prescribed by the Committee.
     A Participant's Pre-tax Contributions will be credited to his Account on a
     payroll-by payroll basis (and, to the extent permitted by law and
     consistent with the Participant's election and the Committee s rules of
     procedure, all or a portion thereof will be immediately contributed to the
     Employees' Savings Plan and appropriately debited from the Account).

4.2  Effective Date of Participation Agreement.

     A Participant's Participation Agreement will become effective on the first
     day of the Plan Year to which it relates. The Participation Agreement of an
     Employee who is first eligible during a Plan Year will become effective as
     of the first day of the month after the Employee completes his
     Participation Agreement, if the Employee completes the Participation
     Agreement within 30 days after the date he first becomes eligible.
     Otherwise, the Employee must wait until the beginning of the following Plan
     Year to begin making Pre-tax Contributions. Participation Agreements relate
     only to compensation earned after they are completed and executed. Except
     as provided above, if a Participant fails to complete a Participation
     Agreement before the first day of the Plan Year in which he or she will
     earn the compensation to which the Participation Agreement relates, the
     Participant will be deemed to have elected not to make Pre-tax
     Contributions for that Plan Year.

4.3  Modification or Revocation of Election by Participant.

     A Participant may not change the amount of his Pre-tax Contributions during
     a Plan Year unless the Committee determines that he has suffered a severe,
     sudden and unforeseeable hardship, as more fully described in Section 7.10.
     Under no circumstances may a Participant's Participation Agreement be made,
     modified or revoked retroactively.

4.4  Employer Make-up Contributions.

     For each Plan Year, the Account of each Participant will be credited with
     the Employer Make-up Contribution determined pursuant to Section 2.1(m).

                                       7

4.5  Employer Matching Make-up Contributions.

     For each Plan Year, the Account of each Participant will be credited with
     the Employer Matching Make-up Contribution determined pursuant to Section
     2.1(n).

5.1  Vesting.

     A Participant will be 100% vested at all times in the amount of his Account
     which is attributable to his Pre-tax Contributions and Employer Matching
     Make-up Contributions. The portion of the Participant's Account
     attributable to Employer Make-up Contributions will vest on the earliest to
     occur of the following dates:

     (a)  the Participant's Retirement Date;

     (b)  the Participant's death; and

     (c)  the date the Participant accrues three years of vesting service under
          the Employees Stock Bonus Plan.

     All provisions of the Plan relating to the distribution of a Participant's
     Account will mean only the vested portion of that Account. Since the Plan
     is unfunded, the portion of a Participant's Account that is not vested and
     therefore not distributed with the vested portion of his Account will
     remain property of the Employer who was responsible for it, and will not be
     allocated to the Accounts of other Participants or otherwise inure to their
     benefit.

5.2  Hypothetical Investment Elections.

     Amounts credited to a Participant's Account will be credited with earnings
     and losses based on hypothetical investments selected by the Committee, as
     described below. The Committee will establish "investment guidelines" that
     prescribe hypothetical allocation (and periodic rebalancing) of account
     credits in specified percentages among a range of mutual funds and other
     investment vehicles chosen according to the "investment objectives" of the
     guidelines. From time to time, the Committee will review the guidelines and
     may adjust them, to redefine the investment objectives, or better to
     achieve existing objectives. Amounts in each account will be credited as of
     each Accounting Date with the gains, or debited with the losses, they would
     have earned or lost since the next preceding Accounting Date if the
     investments had been real, instead of hypothetical.

6.1  Establishment of Bookkeeping Accounts.

     A separate bookkeeping Account will be maintained for each Participant. The
     account will be credited with the Pre-tax Contributions made by the
     Participant pursuant to Section 4.1, the Employer Make-up Contributions
     made by the Employers pursuant to Section 4.4 and the Employer Matching
     Make-up Contributions made by the Employers pursuant to Section 4.5,
     credited (or charged, as the case may be) with the hypothetical investment
     results determined pursuant to Section 5.2, and charged with distributions
     made to or with respect to a Participant.

6.2  Subaccounts.

     Within each Participant's bookkeeping Account, separate subaccounts will be
     maintained to the extent necessary or desirable for the efficient
     administration of the Plan.

6.3  Hypothetical Nature of Accounts.

     The Accounts established under this Article VI will be hypothetical in
     nature and will be maintained for bookkeeping purposes only, so that Pre-
     tax Contributions, Employer Make-up Contributions and Employer Matching
     Make-up Contributions can be credited to Participants and earnings and
     losses on those contributions can be credited (or charged, as the case may
     be). Neither the Plan nor any of the Accounts (or subaccounts) will hold
     any actual funds or assets. The right of any person to receive one or more
     payments under the Plan will be an unsecured claim against the general
     assets of the Employers. Any liability of an Employer to any Participant,
     former Participant, or Beneficiary with respect to a right to payment will
     be based solely upon contractual obligations created by the Plan. Neither
     the Company, any other Employer, the Board, nor any other person will be
     deemed to be a trustee of any amounts to be paid under the Plan. Nothing
     contained in the Plan, and no action taken pursuant to its provisions, will
     create or be construed to create a trust of any kind, or a fiduciary
     relationship, between the Company and a Participant, former Participant,
     Beneficiary, or any other person.

7.1  Timing of Distribution of Benefits.

     a)   Distribution of Contribution to Employees' Savings Plan. No later
          than March 15 of the Plan Year following the Plan Year for which the
          Participant executed the Participation Agreement, the lesser of (i)
          the excess of the allowable pre-tax contribution which may be made on
          behalf of the Participant to the Employees' Savings Plan for the Plan
          Year for which the Participant executed the Participation Agreement
          over the amounts already actually contributed to the Employees'
          Savings for the Plan Year and (ii) the excess of the Pre-tax
          Contributions for the Plan Year for which the Participant executed the
          Participation Agreement over the amounts already actually contributed
          to the Employees' Savings Plan for the Plan Year will be paid directly
          to the Participant's Account in the Employees' Savings Plan, and the
          appropriate subaccounts of Participant's Account in this Plan will be
          debited accordingly. However, the Plan will not make distributions to
          the Employees' Savings Plan in excess of the Participant's Account
          balance. Distributions pursuant to this Section 7.1(a) may be made in
          one or more installments.

     (b)  Distribution After Termination of Employment. Except as provided
          below and in Section 7.1(a), a Participant's entire Account will be
          distributed to him (or his Beneficiary in the event of his death)
          following the earliest to occur of the following:

          (i)   the Participant's death;

          (ii)  the Participant's Retirement Date; and

          (iii) the Participant's other termination of employment with the
                Employer and all affiliates (as defined in the Employees'
                Savings Plan).

          Notwithstanding the foregoing, if a Participant's Retirement Date is
          on account of disability, as described in Section 2.1(u)(ii), and if
          the Participant so requests and the Committee permits it, the
          Participant may defer distribution until the earlier of the dates
          specified in Section 2.1(u)(i)(A) or 2.1(u)(i)(B) or the Participant's
          death.

                                      11

7.2  Time of Distribution and Accounting.

     When a distributable event described in Section 7.1(b) occurs, the balance
     of a Participant's Account will be determined, as of the Accounting Date
     immediately following the distributable event. Distribution will be made or
     begin as soon as practicable after the accounting or ninety days following
     the distributable event, whichever is later.

7.3  Form of Payment or Payments.

     If the value of the Participant's Account as of the Accounting Date
     described in Section 7.2 is at least $25,000, benefits payable after the
     Participant's Retirement Date will be paid in the form elected by the
     Participant. The form elected will apply to the entire Account. The
     election may be amended, provided that the amended election does not
     increase the duration of payments in the previous election and the election
     is made no later than December 31 of the calendar year before the
     Participant's Retirement Date. Available forms of distribution are:

     (a)  payment by lump sum; and

     (b)  payment in substantially equal monthly installments over a period of
          sixty, 120, or 180 months, or substantially equal annual installments
          over a period of five, ten, or fifteen years. During the payout
          period, hypothetical earnings on the unpaid balance will continue to
          be credited to subaccounts at the appropriate rate, in accordance with
          the Participant's hypothetical investment election.

     If, as of the Accounting Date described in Section 7.2, the value of the
     Participant's Account is less than $25,000, the form of distribution will
     be by lump sum payment. If a former Participant dies after installment
     payments have begun, but before distribution of his entire Account has been
     completed, distributions will be continued to his Beneficiary in the form
     that was being paid before his death.

                                      12

7.4  Accelerated Distribution.

     Notwithstanding any other provision of the Plan, a Participant will be
     entitled to receive, upon written request to the Committee, a lump sum
     distribution of his Account balance, valued as of the Accounting Date
     immediately following the date he makes his request.  A Participant who
     makes such a request will forfeit ten percent of the Account balance as so
     valued, as a penalty.  A Participant who receives a distribution under this
     Section 7.4 will not be eligible to make Pre-tax Contributions until the
     first day of the second Plan Year which begins after that distribution.  A
     distribution under this section 7.4 will be made as soon as practicable
     after the Committee receives the Participant's written request and the
     Account has been valued.

7.5  Designation of Beneficiaries.

     Each Participant will have the right, at any time, to designate one or more
     persons or an entity as a Beneficiary (joint, primary or secondary) to whom
     his benefits under this Plan will be paid if he dies before his Account has
     been completely distributed.  Each Beneficiary designation must be in a
     written form prescribed by the Committee and will be effective only when
     filed with the Committee during the Participant's lifetime.  Designation by
     a married Participant of a Beneficiary other than his spouse will not be
     effective unless the spouse executes a written consent that acknowledges
     the effect of the designation and is witnessed by a notary public, or
     unless the consent cannot be obtained because the spouse cannot be located.

7.6  Amendments of Beneficiary Designations.

     Except as provided below, any designation of Beneficiary other than the
     Participant's spouse may be changed by a Participant without the consent of
     that Beneficiary, merely by the Participant's filing a new designation with
     the Committee.  The filing of a new designation will cancel all
     designations previously filed.

7.7  Change in Marital Status.

     If the Participant's marital status changes after he has designated a
     Beneficiary, the following rules will apply.

     (a)  If the Participant is married at death but was unmarried when the
          designation was made, the designation will be void unless the spouse
          has consented to it in the manner described in Section 7.5 or is the
          Beneficiary named in the designation.

     (b)  If the Participant is unmarried at death but was married when the
          designation was made:

          (i)  the designation will be void if the spouse was named as
               Beneficiary; and

          (ii) the designation will remain valid if a Beneficiary other than the
               individual to whom the Participant was married at the time of the
               designation was named.

                                       13
<PAGE>
 
     (c)  If the Participant was married when the designation was made and is
          married to a different spouse at death, the designation will be void
          unless the new spouse has consented to it in the manner described in
          Section 7.5, or unless the individual who is the Participant's spouse
          at the Participant's death was named as the Beneficiary.

7.8  No Beneficiary Designation.

     If any Participant fails to designate a Beneficiary in the manner provided
     above, or if the Beneficiary designated by a deceased Participant dies
     before the Participant or before complete distribution of the Participant's
     benefits, the Participant's Beneficiary will be the person in the first of
     the following classes in which there is a survivor:

     (a)  the Participant's surviving spouse;

     (b)  the Participant's children in equal shares, except that if any of the
          children predeceases the Participant but leaves issue surviving, then
          such issue will take by right of representation the share the parent
          would have taken if living; and

     (c)  the Participant's estate.

7.9  Unclaimed Benefits.

     If the Committee is unable to locate the Participant or beneficiary to whom
     a benefit is payable, the benefit will be forfeited to the Employer or
     Employers who made the contributions on behalf of the Participant, if the
     Committee so decides.  Notwithstanding the foregoing, if after any such
     forfeiture the Participant or beneficiary to whom the benefit was payable
     makes a valid claim for the benefit, it will be paid by the Employer or
     restored to the Plan by the Employer.

7.10 Hardship Withdrawals.

     A Participant may apply in writing to the Committee for, and the Committee
     may permit, a hardship withdrawal of all or any part of a Participant's
     Account, valued as of the Accounting Date immediately following the date
     the application is made.  The Committee will grant a hardship withdrawal
     under this Section 7.10 only if it determines in its sole and absolute
     discretion that the Participant has incurred a severe financial hardship
     resulting from a sudden and unexpected illness or accident of the
     Participant or of the Participant's dependent (as defined in Section 152(a)
     of the Code), a loss of the Participant's property due to casualty, or
     another similar extraordinary and unforeseeable set of circumstances
     arising as a result of events beyond the control of the Participant, as
     determined by the Committee.  The amount that may be withdrawn will be
     limited to the amount reasonably necessary to relieve the hardship or
     financial emergency upon which the request is based, plus the federal and
     state taxes due on the withdrawal, as determined by the Committee.  The
     Committee may require a Participant who requests a hardship withdrawal to
     submit evidence the Committee, in its sole discretion, deems necessary or
     appropriate to substantiate the hardship withdrawal request.  A Participant
     who receives a

                                       14
<PAGE>
 
      hardship withdrawal under this Section 7.10 will not be eligible to make
      Pre-tax Contributions until the first day of the next Plan Year.

7.11  Withholding.

      All contributions, hypothetical earnings (if any) on contributions and
      distributions under this Plan will be subject to legally required income
      and employment tax withholding.

8.1  Committee.

     The Plan will be administered by a Committee, which will consist of the
     members of the Company Stock Option Advisory Committee of the Board.  The
     Committee will be responsible for the general operation and administration
     of the Plan and for carrying out its provisions.  The Committee may
     delegate certain of its responsibilities under the Plan to others,
     including officers and employees of the Employers, advisors and individuals
     qualified to undertake Plan ministerial duties, so long as the delegation
     is in writing.  No member of the Committee who is a Participant may
     participate in any matter relating to his status as a Participant or his
     rights or entitlement to benefits as a Participant.

8.2  General Powers of Administration.

     The Committee will have all powers necessary or appropriate to enable it to
     carry out its administrative duties.  Not in limitation, but in
     illustration of the foregoing, the Committee will have discretionary
     authority to construe and interpret the Plan and determine all questions
     that may arise hereunder as to the status and rights of Employees,
     Participants, Beneficiaries and others.  The Committee may exercise its
     powers in its sole and absolute discretion.  The Committee may promulgate
     such regulations as it deems appropriate for the operation and
     administration of the Plan.  No member of the Committee will be personally
     liable for any actions taken by the Committee unless the member acted with
     willful misconduct.

8.3  Indemnification of Committee.

     The Company will indemnify the members of the Committee against any and all
     claims, losses, damages and expenses, including attorney's fees, incurred
     by them, and against any liability, including any amounts paid in
     settlement with their approval, arising from their action or failure to
     act, except when the action or failure to act is judicially determined to
     be attributable to the members' gross negligence or willful misconduct.

                      CLAIMS PROCEDURE AND ADMINISTRATION
                                        

9.1  Claims.

     A person who believes that he is being denied a benefit to which he is
     entitled under the Plan may file a written request for the benefit with the
     Committee, setting forth his claim.  The request must be addressed to the
     Committee at the Company at its then principal place of business.

9.2  Claim Decision.

     Upon receipt of a claim, the Committee will advise the claimant that a
     reply will be forthcoming within ninety days and will, in fact, deliver its
     reply within that period.  The Committee may, however, extend the reply
     period for an additional ninety days for reasonable cause, so long as it
     gives the claimant advance notice of the need for an extension.

     If the Committee denies the claim in whole or in part, the Committee will
     adopt a written opinion, using language calculated to be understood by the
     claimant, setting forth:

     (a)  the specific reason or reasons for the denial;

     (b)  specific references to the Plan provisions on which the denial is
          based;

     (c)  a description of any additional material or information necessary for
          the claimant to perfect his claim and an explanation why the material
          or information is necessary;

     (d)  appropriate information as to the steps to be taken if the claimant
          wishes to submit the claim for review; and

     (e)  the time limits for requesting a review under Section 9.3 and for
          review under Section 9.4 hereof.

9.3  Request for Review.

     Within sixty days after the Claimant receives the written opinion described
     above, he may request in writing that the Secretary of the Company (the
     "Secretary") review the Committee's determination.  The request must be
     addressed to the Secretary of the Company at its then principal place of
     business.  The claimant or his duly authorized representative may, but need
     not, review the pertinent documents and submit issues and comments in
     writing for consideration by the Secretary.  If the claimant does not

     receiving the Committee's opinion, he will be barred and stopped from
     challenging the Committee's determination.

9.4  Review of Decision.

     Within sixty days after the Secretary's receipt of a request for review, he
     will review the Committee's determination.  After considering all materials
     presented by the claimant, the Secretary will render a written opinion,

     forth the specific reasons for the decision and containing specific
     references to the provisions of the Plan on which the decision is based.
     If special circumstances require that the sixty-day time period be
     extended, the Secretary will notify the claimant and will render the
     decision as soon as possible, but no later than 120 days after receipt of
     the request for review.

9.5  Discretionary Authority.

     The Committee and Secretary will have complete discretionary authority to
     determine a claimant's entitlement to benefits upon his claim or his
     request for review of a denied claim, respectively.

10.1  Plan Not a Contract of Employment.

      The adoption and maintenance of the Plan will not be or be deemed to be a
      contract between the Company and any person, or to be consideration for
      the employment of any person. Nothing in this Plan will give or be deemed
      to give any person the right to be retained in the employ of an Employer
      or the right to restrict an Employer's right to discharge any person at
      any time; nor will the Plan give or be deemed to give an Employer the
      right to require any person to remain in the employ of the Employer, or to
      restrict any person's right to terminate his employment at any time.

10.2  Non-Assignability of Benefits.

      No Participant, Beneficiary or distributee of benefits under the Plan will
      have any power or right to transfer, assign, anticipate, hypothecate or
      otherwise encumber any part or all of the amounts payable hereunder, which
      are expressly declared to be unassignable and non-transferable. Any such
      attempted assignment or transfer will be void. No amount payable under the
      Plan will, prior to actual payment thereof, be subject to seizure by any
      creditor of any Participant, Beneficiary or other distributee for the
      payment of any debt, judgment, or other obligation, by a proceeding at law
      or in equity, nor transferable by operation of law in the event of the
      bankruptcy, insolvency or death of a Participant, Beneficiary or other
      distributee hereunder.

10.3  Amendment and Termination.

      The Board (or any person authorized by the Board) may from time to time,
      in its discretion, amend, in whole or in part, any or all of the
      provisions of the Plan; provided, however, that no amendment may be made
      which would impair the rights of a Participant to amounts already
      allocated to his Account. The Board may terminate the Plan at any time. If
      the Plan is terminated, the balance in a Participant's Account will be
      paid to the Participant or his Beneficiary in a lump sum or in equal
      monthly installments, as determined by the Committee.

10.4  Unsecured General Creditor Status Of Employee.

      The payments to a Participant, his Beneficiary or any other distributee
      hereunder will be made from assets which will continue, for all purposes,
      to be a part of the general, unrestricted assets of the Employers; no
      person will have nor acquire any interest in any such assets by virtue of
      the provisions of this Agreement. An Employer's obligation hereunder will
      be an unfunded and unsecured promise to pay money in the future. To the
      extent that the Participant, a Beneficiary, or other distributee acquires
      a right to receive payments from the Employer under the provisions hereof,
      such right will be no greater than the right of any unsecured general
      creditor of the Employer; no such person will have nor require any legal
      or equitable right, interest or claim in or to any property or assets of

                                       19
<PAGE>
 
      the Employer. If, in its discretion, the Employer purchases an insurance
      policy or policies insuring the life of the Participant (or any other
      property), or establishes a grantor trust, to allow the Employer to
      recover the cost of providing the benefits, in whole, or in part,
      hereunder, neither the Participant, his Beneficiary nor any other
      distributee will have nor acquire any rights whatsoever therein or in the
      proceeds therefrom. The Employer will be the sole owner and beneficiary of
      any such insurance policy or policies and, as such, will possess and may
      exercise all incidents of ownership therein. Except as described in
      Section 1.4, no such policy, policies or other property will be held in
      any trust for a Participant, Beneficiary or other distributee or held as
      collateral security for any obligation of an Employer hereunder.

10.5  Severability.

      If any provision of this Plan is held to be illegal or invalid for any
      reason, the illegality or invalidity will not affect the remaining
      provisions hereof; instead, each provision will be fully severable and the
      Plan will be construed and enforced as if the illegal or invalid provision
      had never been included in it.

10.6  Governing Laws.

      All provisions of the Plan will be construed in accordance with the laws
      of Illinois, except to the extent preempted by federal law.

10.7  Binding Effect.

      This Plan will be binding on each Participant and his heirs and legal
      representatives and on the Employers and their successors and assigns.

10.8  Entire Agreement.

      This document and any amendments contain all the terms and provisions of
      the Plan and will constitute the entire Plan, any other alleged terms or
      provisions being of no effect.

          IN WITNESS WHEREOF, the Company has caused this Plan to be executed on
the _______________ day of October, 1997.

TO OUR SHAREHOLDERS
 
- -------------------------------------------------------------------------------
  You probably can tell this Annual Report was produced inexpensively. Rather
than spending the extra money painting the lily, we decided to let our past
year's stellar performance speak for itself.
 
  And how well did we do? Well, our earnings totaled $13.8 million, up a spec-
tacular 94% from last year. Even setting aside our $5.1 million net gain from
the sale of our credit card portfolio, First Oak Brook's core earnings rose to
$8.7 million in 1997 from $7.1 million in 1996, a 22% increase. And 1997
shareholders' equity climbed to $71.7 million from $59.6 million the year be-
fore, up 20%.
 
  Enjoying an outstanding return on average equity of 21.72% and return on av-
erage assets of 1.76%, we were very comfortable boosting dividends for the
sixth consecutive year and initiating our first stock buy back program.
 
  Evidently, the market responded, rewarding shareholders with an unprece-
dented gain in our stock price. Our Class A common stock opened at $23.25 per
share on January 1, 1997 and closed at $48 per share on December 31, 1997,
more than doubling over the year. More to the point, our Company's stock
outperformed the indexes. We'd like to suggest some possible explanations for
this.
 
                          ENHANCING SHAREHOLDER VALUE
 
  We now recognize managing our bank well and enhancing shareholder value are
not synonymous, although they remain closely related. We are more focused than
ever before on the advantages of stock buy back programs, which raise per
share earnings; increased dividends, which put cash in our investors' pockets;
stock splits, which enhance liquidity and market interest; and stock option
plans, which better align management and shareholder objectives. Our growing
size, desirable location, and valuable franchise have been attracting invest-
ors; we're also taking more direct action to encourage their interest. In the
past, we tended to think of visits from the investment community as distrac-
tions keeping us from our customers. Now we think of them as opportunities and
act accordingly.
 
                      BUILDING ON OUR STRENGTHS: A REVIEW
 
  We have learned that the same kind of dispassionate and objective examina-
tion of our business that can work so well for investment analysts can also
work for us. Thus, as 1997 began, we looked closely at each of our major busi-
ness divisions. In some of our strongest performing areas, we made crucial
changes. Here are details:
 
COMMERCIAL BANKING AND CASH MANAGEMENT. Historic sources of growth and profit,
these related departments develop, sell, install and service cash management
products for business, the professions and the public sector. Our objective is
to continue to build the business development and relationship management
staff and to introduce custom-made and innovative products for this sophisti-
cated business market. We certainly are well on our way to our goals. In 1997
we brought in approximately $30 million in new checking accounts or fee equiv-
alents. We expanded our front-line to 17 people. We made important product im-
provements, including a complex new lockbox/electronic data interchange serv-
ice (LBX/EDI) and a Windows-based enhancement to our electronic banking serv-
ice (EBS); and we're about to unveil an Internet-based version of our elec-
tronic banking service (WEBSSM), one of the first of its kind in the U.S.
 
COMMERCIAL REAL ESTATE LENDING. Another growth engine, commercial real estate
lending, enjoyed a profitable year in 1997, expanding to $109.9 million from
$99.3 million. Although our portfolio is diversified, we exploited our special
expertise in lending to home builders. Yields remained relatively attractive.
We introduced a successful direct mail marketing program. Our top lenders re-
mained in place, and we strengthened support staff.

- -------------------------------------------------------------------------------
 
CONSUMER LOANS. Consumer loans consist of two principal categories--indirect
auto loans and home equity lines. Our indirect auto loan business exploded in
1997 to $105.8 million from $58.6 million in 1996. We have, by design, become
an area leader in making consumer auto loans through a network of car dealers.
In fact, in 1997 we placed 7th in new car and 10th in used car bank loan orig-
inations for the Chicago area according to the Cross-Sell Report, whereas,
previously, we had not made the top 40. And we are particularly pleased we
achieved this remarkable result while incurring only $39,000 in losses on 12
loans out of a portfolio of over 8,300 loans. Our success depends on competi-
tive pricing, fast turnarounds and consistent buying habits. To sharpen our
edge while increasing our capacity for business development, we expanded our
staff to 8 in 1997 from 4 in 1996.
 
  Our home equity line business expanded in 1997 as outstandings rose to $65.3
million from $55.3 million, growing 18%. Chicago-area radio continues as our
principal marketing vehicle, promoting our under prime rates for larger lines
of credit. We refined our Call Center, which opened in late 1996, so that ap-
plications for home equity lines, direct auto loans and several other types of
consumer loans could be taken by phone.
 
INVESTMENT MANAGEMENT AND TRUST DEPARTMENT. The growth in Investment Manage-
ment and Trust Department (IM&T) income and assets coincides with our strategy
over the last five years to produce an increase in discretionary investment
assets under management. Until then our IM&T Department operated largely as an
accommodation to our banking customers.
 
  Our focused effort, with help from the recent bull market, has produced out-
standing results. Discretionary assets under management rose to $134 million
in 1997 from $91 million in 1996. Income from all sources climbed to $1.025
million from $653 thousand the prior year, allowing that $147 thousand of this
increase resulted from a one-time shift in billing practice to quarterly in
1997 from annually in arrears in 1996.
 
  To fortify our efforts, we hired our first full-time business development
officer in October, 1996. His specialty is selling investment management serv-
ices primarily to police and fire retirement funds, of which we now have 9 as
clients. We hired an attorney to work full-time on land trusts, so our other
administrators can focus on discretionary asset management. And in February,
1998, we engaged a new head of the IM&T Department, who comes to us with ex-
tensive investment experience.
 
  Also, in August, 1997 we selected Pacific Income Advisors (PIA), a spin-off
from Security Pacific Bank, as a sub-investment advisor on our large-capital-
ization, value-oriented managed funds. So far, PIA's results have been excel-
lent. Clients also appreciated another investment approach, mutual fund asset-
allocation modeling. Here, for a modest fee, we advise clients on a mix of no-
load mutual funds to support their lifestyles and meet their investment goals.
 
  All these initiatives are intended to help us become a leading provider of
investment management services to individuals, professionals, middle market
businesses, and the public sector throughout the western suburbs.
 
                        FIXING OUR WEAKNESSES: A REVIEW
 
  As we wrote in last year's Annual Report, we also began 1997 by identifying
a few areas which needed attention. Here's what we did about them:
 
CREDIT CARDS. After years of leading the credit card industry with low rates
and top service, we found we lacked the resources to compete against even big-
ger and more aggressive companies. Our credit card business had stayed very
profitable but wasn't growing. Our low cost position in the market was erod-
ing. Our revolving credit users were being attracted by teaser rates, and our
convenience users
                                                                              3

TO OUR SHAREHOLDERS
 
- -------------------------------------------------------------------------------
were being lured away by rebate programs. We were doing well just maintaining
our portfolio. The big players had been buying business; we couldn't afford
the same tactics.
 
  We considered two alternatives:
 
  . Stay in the business, and go after affinity card sponsors who want to
    provide a low-cost card for their members, rather than a high revenue
    stream for themselves. While this niche is only a small fraction of the
    market, it fit best with our resources and reputation.
 
  . Sell the business at a price warranted by the quality of our portfolio
    and sufficient to preserve our income stream for at least five years,
    while making sure our loyal customers continued to receive outstanding
    service.
 
  We chose the second alternative, and the portfolio sale we completed in mid-
1997 achieved all our objectives. We received an immediate after-tax premium,
net of expenses, of $5.1 million. We entered into a revenue-sharing agreement
on the sold portfolio that, coupled with the income on the reinvested princi-
pal, should produce a return for five years approximating our previous profit.
And we sold the portfolio to an organization recognized for superior service.
 
  This was a difficult decision for us because we knew it could hurt loyal em-
ployees. But this tough choice turned out to be the right one. With our growth
and a very tight job market, we were able to place most of the displaced staff
in other jobs in our own Company. In the end, we strengthened several growing
areas of the bank.
 
RETAIL BANKING. Gathering retail deposits still centers on walk-in business at
branches. That's one reason, to depositors, quality service means having a
convenient location. And that's why branches, although expensive, are likely
to continue as the premier retail delivery channel for the foreseeable future.
In this context, we have staked out the western suburbs of Chicago as our pri-
mary market. Area demographics remain outstanding. DuPage County, the heart of
our market, has an estimated population of 859,000 and enjoys the highest me-
dian family income of any county in Illinois and the twentieth highest nation-
ally.
 
  However, as we examined our branch costs, we realized we had gotten a little
off track. Generally, we had located offices in communities with both growing
consumer and commercial bases, with the expectation that consumer business
would cover our initial costs and commercial accounts would produce long-term
growth and profit. Unfortunately, in certain cases we had built up retail
staff at the expense of outside commercial new business staff. We began to
correct this imbalance in 1997.
 
  We also found inefficiencies. For example, banking hours in some cases did
not coincide with customer preferences. We typically maintained late hours on
Friday nights because years ago it was a popular time to cash the weekly pay-
check or float a car loan. With direct deposit of most payrolls, the prolifer-
ation of ATMs, and the car loan business migrating into dealer showrooms, such
extended Friday hours are an anachronism. We adjusted them.
 
  Meanwhile, we introduced new technology where appropriate. A simple computer
model now allows us to identify and pay special attention to our better cus-
tomers who account for virtually all retail banking profits.
 
  To cover our costs and associated risks, we also began charging non-custom-
ers for cashing checks and using our ATMs.
 
  For 1998, we are working on a number of initiatives. We have already intro-
duced a new Individual Cash Management Checking Account which combines check-
ing and investment features, so cus-

- -------------------------------------------------------------------------------
tomers don't have to transfer cash back and forth between checking and higher
interest accounts. This new checking account pays regular checking interest on
smaller balances and a high savings rate on balances over $10,000. We are also
planning to modify our other checking and savings products to eliminate com-
plexity and reward our better customers with extra features. And we're happily
saying goodbye to the avalanche of paper that used to jam our CD system.
 
  Before the year is up, we expect to introduce check imaging, which will give
customers images of their checks each month, instead of the originals. Later,
when we introduce home banking, customers will be able to see their checks as
soon as they clear, instead of having to wait until the end of the month.
 
  But the success of our retail banking will depend on more than technology.
The Retail Banking Department is focusing on ways to please our customers at
each and every point of contact. We already have introduced Customer Apprecia-
tion Days, and we celebrate holidays like Valentine's Day, Mother's Day, Fa-
ther's Day, and Halloween with special gifts. We thank our customers when they
open an account, and we let our best customers know we appreciate them during
the holidays each December. We think our customers will value these and other
courtesies greatly.
 
COMMERCIAL LENDING. Finally, commercial lending was lagging. Despite the ex-
panding economy, commercial loans totaled just $40.9 million at year-end 1996
compared to $38.2 million at the end of 1995; worse still, commercial loans
represented a meager 9.7% of total loans in 1996, down from 10.5% in 1995. We
found new leadership for the commercial loan group in 1997 and streamlined the
decision-making process to improve our responsiveness. Consequently, we ended
1997 with $54.7 million in outstandings. Our long-term goal is to make commer-
cial lending as important as commercial deposit gathering.
 
                                  OTHER PLANS
 
NEW TECHNOLOGY. In the coming year, we'll have new challenges to face. As the
wave of new banking technology speeds along, we must work even harder to stay
on the leading edge. Our commitment manifests itself in some of our future
projects: a more powerful IBM AS400 computer, check imaging, business and home
banking over the Internet, a new system to process consumer loan applications,
a new computerized system for opening retail accounts, a new platform system
to simplify loan operations input, and upgrades to the Call Center, not to
mention 66 replacement Pentium II PC installations. Also, of course, our IT
Department is examining and testing "Year 2000" solutions.
 
  We have to bear in mind that advancement doesn't come without its costs,
even beyond the money spent. Every time we install new computer equipment or
software, it's as if we all become trainees again until everybody in the or-
ganization readjusts. Also, we must continue to hire and train talented new
people in a very tight job market.
 
EXPANSION. We're expanding. In early January 1998, we opened our new Aurora
branch. This elegant new Federalist style office, situated at the entrance to
the upscale Stonegate community, will serve both residents of eastern Aurora
and western Naperville and businesses throughout the Fox Valley area.
 
  We also acquired a location for a new branch in downtown Glen Ellyn, another
attractive DuPage County community. We have all necessary approvals in hand
and have sent plans out for bid. We expect this office to open late in 1998.
 
  And we are seeking additional sites. Even though new branches retard short-
term earnings, we believe our market warrants judicious office additions.
                                                                              5

TO OUR SHAREHOLDERS
 
- -------------------------------------------------------------------------------
 
  Meanwhile, we're keeping an eye out for acquisitions. Recently, bank acqui-
sitions have been growing larger, and some smaller financial institutions are
starting to recognize that it may be wise to merge with a company our size.
Non-bank acquisitions, such as insurance brokerages, are also a possibility.
Moreover, the recent uptick in our stock price gives us an attractive currency
for such deals. We are committed to a very disciplined approach to acquisi-
tions. Our expectation is to optimize current and future earnings streams, ob-
tain logical market extensions and exploit economies of scale.
 
THE OAK BROOK BANK CHARITABLE FOUNDATION. Part of being a leader means sup-
porting good causes in the communities we serve. Hence, at the end of 1997, we
established the Oak Brook Bank Charitable Foundation with an initial gift of
$300,000. While this donation slightly reduced 1997 profits, it allowed us to
take advantage of the higher 38% marginal tax bracket our credit card sale put
us in; it gave us leeway to invest in equities as well as debt; and it pro-
vides us with ample funds to help low and moderate income families within our
Community Reinvestment Act (CRA) assessment area.
 
LOOKING FORWARD. In 1998, we'll most likely continue to be challenged by our
asset growth and technological sophistication. Of course, many organizations
in less desirable markets dream of facing such problems, so we're not com-
plaining. You can be sure we'll be working harder than ever during the coming
year to reinforce our position of banking leadership in Chicago's western sub-
urbs.
 
GOODBYE, AL. Lastly, let us wish a fond farewell to Al Withers, who passed
away in November, 1997 after serving as Director so ably and long. The Board
will miss this Texan's practical advice and good humor.

1997 versus 1996
 
A significant change in 1997 net income was the gain on the sale of the credit
card portfolio. The Company recognized an after-tax gain of $5.1 million on the
sale. The net gain consisted of a premium of $11.5 million less expenses of
$2.25 million, an $800,000 special provision for loan losses and an income tax
provision of $3.3 million. In addition the Company will share in the revenue
from the sold portfolio for each of the next five twelve month periods begin-
ning July of 1997, subject to a maximum annual payment of $900,000. Results for
1997, excluding the gain on the sale of the credit card portfolio follow:
 
<TABLE>
<S>                         <C>
Net income                  $8,670,000
Basic earnings per share    $     2.63
Diluted earnings per share  $     2.56
Return on average assets          1.11%
Return on average equity         13.69%
</TABLE>
 
As detailed below, the sale of the credit card portfolio affects the compara-
bility of virtually every line item in the financial statements.
 
The 1997 results compared to 1996 include the following significant pre-tax
components:
 
 . Net interest income rose $598,000 due to a 7% increase in average earning as-
  sets offset by a 5% decrease in the net interest margin.
 
 . Other income, excluding the gain on the credit card portfolio sale, increased
  $1,643,000 primarily due to income earned from the revenue sharing agreement
  on the sold credit card portfolio amounting to $450,000 in 1997, as well as
  higher fees from business deposit accounts, investment management and trust
  accounts, and merchant card processing.
 
 . Salaries and employee benefits increased $527,000 due to normal salary in-
  creases, higher compensation due to competitive market conditions, additional
  upgrades and increased staff in core growth areas, offset by the elimination
  of salaries in the credit card department due to the sale of the credit card
  portfolio.
 
 . Data processing fees decreased $324,000 primarily due to the sale of the
  credit card portfolio.
 
 . Included in other operating expense was a $300,000 contribution made to the
  newly established Oak Brook Bank Charitable Foundation.
 
 . Included in other operating expense was a $515,000 gain on the sale of sur-
  plus property formerly leased to a third party.
 
1996 versus 1995
 
The 1996 results compared to 1995 include the following significant pre-tax
components:
 
 . Net interest income rose $1,358,000 due to a 13% increase in average earning
  assets, offset by a 7% decrease in the net interest margin.
 
 . Management increased the provision for loan losses by $460,000 considering
  loan portfolio growth, higher credit card losses and one nonaccrual loan.
 
 . Other income increased $461,000 due to increased fee income from business de-
  posit accounts, investment management and trust accounts, mortgages sold in
  the secondary market and merchant credit card processing, offset by a
  decrease in investment securities gains of $113,000.
 
 . Salaries and employee benefits increased $845,000 due to additional staffing,
  normal salary increases and higher benefit payments.
 
 . Advertising and business development expenses decreased $189,000 due to a re-
  duction in advertising, offset by increased business development costs.
 
 . FDIC premiums decreased $590,000 as a result of lower FDIC premiums for
  "well-capitalized" banks which became effective January 1, 1996.
 
NET INTEREST INCOME
 
Net interest income is the difference between interest earned on loans, invest-
ments and other earning assets and interest paid on deposits and other inter-
est-bearing liabilities. Net interest income is the principal source of the
Company's revenues.
 
1997 versus 1996
 
On a tax-equivalent basis, net interest income for 1997 totaled $28,591,000, an
increase of $438,000 or 2% over
8

1996. This increase is attributable to a 7% increase in average earning assets
offset by a 5% decrease in the net interest margin to 3.97% in 1997 from 4.20%
in 1996. The compression of the net interest margin was a result of the follow-
ing:
 
 . On June 30, 1997, the Company sold its credit card portfolio which totalled
  approximately $53 million and had a gross yield of approximately 16%. The net
  proceeds from the sale of approximately $58 million were reinvested in the
  bank's securities portfolio at an approximate yield of 7%. While the interest
  income stream combined with the future revenue sharing payments and reduced
  expenses associated with the sale had a neutral to slightly positive effect
  on earnings, the net interest margin was compressed for the second six months
  of 1997.
 
 . Further compression of the net interest margin in 1997 was offset by a slight
  increase in the average prime rate to 8.44% in 1997 from 8.27% in 1996 and
  the growth in average loans. Average loans increased $24 million primarily in
  indirect auto loans ($30 million), home equity loans ($9.4 million) and com-
  mercial loans ($9.4 million), offset by credit card loans dropping $27.2 mil-
  lion.
 
 . The cost of average interest-bearing liabilities rose to 4.89% in 1997 from
  4.80% in 1996. The 1997 average balance for higher rate time deposits in-
  creased $21.2 million compared to 1996 while the 1997 average balance for
  lower rate savings and NOW accounts declined $13.7 million compared to 1996.
  Financial institutions bid up rates to mitigate a continuing shift in in-
  vestor preference for the securities markets. To fund the loan growth at
  lower rates than it would have had to pay on deposits, the Company increased
  its Federal Home Loan Bank borrowings by $12.6 million on average in 1997.
 
1996 versus 1995
 
On a tax-equivalent basis, net interest income for 1996 totaled $28,153,000, an
increase of $1,266,000 or 5% over 1995. This increase is attributable to a 13%
increase in average earning assets offset by a 7% decrease in the net interest
margin to 4.20% in 1996 from 4.54% in 1995. The compression of the net interest
margin was a result of the following:
 
 . During 1996, the prime rate averaged 8.27%, while in 1995 the prime rate av-
  eraged 8.83%. Annual yields on earning assets for 1996 reflect this decrease,
  declining 35 basis points in comparison with 1995. Lower rates paid on inter-
  est bearing liabilities were offset by a $69 million increase in the average
  balance of time deposits. The net effect of the rate decreases and the change
  in deposit mix was a decline of only one basis point in the rate on interest
  bearing liabilities.
 
 . Retail consumers continued to show a strong preference for longer-term,
  higher yielding CDs over shorter-term, lower yielding savings and money mar-
  ket accounts. The 1996 average balance for time deposits increased $69 mil-
  lion compared to 1995 while the 1996 average balance for savings and money
  market accounts declined $11 million compared to 1995. Competitive pressure
  for consumer dollars from financial institutions and high returns in the eq-
  uity markets kept CD rates relatively high.
 
 . Further compression of the net interest margin in 1996 was offset by the 21%
  growth in average loans. The $67 million increase in average loans was pri-
  marily in real estate (commercial and residential) and indirect auto loans.
  Credit card growth was constrained as a result of vigorous competition.
                                                                               9

The following table presents a summary analysis of changes in interest income
and interest expense for 1997 as compared to 1996 and 1996 as compared to 1995.
Interest income rose in 1997 due to the higher volume of loans and securities
offset by a decline in average loan yields due to sale of the credit card port-
folio. Interest expense rose in 1997 due to the increased volume of time depos-
its and Federal Home Loan Bank borrowings. The increase in net interest income
in 1996 was due to the increased volume of loans offset by higher volume of
time deposits.

ALLOWANCE AND PROVISION FOR LOAN LOSSES
 
Loans which are determined to be uncollectible are charged off against the al-
lowance and recoveries of loans that were previously charged off are credited
to the
allowance.
 
The Company's charge-off policy varies with respect to the category of and spe-
cific circumstances surrounding each loan under consideration. The Company's
policy with respect to commercial, real estate, indirect auto and other loans
is to charge-off on the basis of management's ongoing evaluation of
collectibility. With respect to credit card loans, charge-offs are made on all
such loans when they are deemed to be uncollectible or when 180 days past due,
whichever comes first. In addition, any loans which are classified as "loss" in
regulatory examinations are charged off.
 
                                                                              11

</TABLE>
 
The provision for loan losses increased $40,000 in 1997 over 1996. When the
credit card portfolio was sold, the bank retained approximately $1.3 million in
outstandings, approximately one third of which consisted of accounts delinquent
60 days or more and the remainder of which were accounts on fixed payment
schedules. Based on a review of these accounts, management determined that a
special $800,000 provision was prudent given the discontinued credit card oper-
ations and the inherent risks related to the accounts.
 
Net charge-offs totalled $1,330,000 in 1997 or .32% of average loans outstand-
ing. Of the total net charge-offs, $1,072,000 related to the credit card port-
folio and $200,000 related to a charge-off on the $1.7 million nonaccrual loan
outstanding at December 31, 1996.
 
Management increased the provision for loan losses by $460,000 in 1996 over
1995 considering loan portfolio growth of $57 million, higher credit card
charge-offs and one nonaccrual loan. Net charge-offs totalled $1,333,000 in
1996 up $356,000 from 1995. Economic trends of higher consumer debt and a rise
in consumer bankruptcies contributed to the increase in credit card losses for
both the Company and the industry.
 
Currently and historically, the Company has had high asset quality. Fluctua-
tions in asset quality ratios in the current period were positively affected by
a repayment of $1.5 million on the nonaccrual loan of $1.7 million outstanding
at December 31, 1996. See nonperforming assets discussion for further informa-
tion.
 
The Company's allowance for loan losses as a percent of loans outstanding was
 .97% at December 31, 1997 as compared to .98% in 1996 and 1.08% in 1995. Man-
agement believes the allowance for loan losses is at a prudent level.
 
The provision for loan losses is sufficient to provide for current loan losses
and maintain the allowance at an adequate level commensurate with management's
evaluation of the risks inherent in the loan portfolio. In order to identify
potential risks in the loan portfolio of the Company's bank subsidiary and de-
termine the necessary provision for loan losses, detailed information is ob-
tained from the following sources:
 
 . Regular reports prepared by the bank's management which contain information
  on the overall characteristics of the loan portfolio, including delinquencies
  and nonaccruals, and specific analysis of loans requiring special attention
  (i.e. "watch lists");

- --------------------------------------------------------------------------------
 
 . Examinations of the loan portfolio of the subsidiary bank by Federal and
  State regulatory agencies; and
 
 . Reviews by the independent auditors, third party consultants and internal au-
  dit staff.
 
Management of the subsidiary bank prepares a detailed analysis, at least quar-
terly, reviewing the adequacy of its allowance and, when appropriate, recom-
mending an increase or decrease in its provision for loan losses. This analysis
is divided into two parts--one for allocated and the other for unallocated re-
serves. The allocated segment involves primarily an estimated calculation of
losses on specific problem and management watch list loans, the remaining
credit card portfolio and delinquent consumer loans. The unallocated segment
involves primarily a calculation of the bank's actual net charge-off history
averaged with industry net charge-off history by major loan categories. In ad-
dition, the bank considers its loan growth, management capabilities, economic
trends, credit concentrations, industry risks, underlying collateral values and
the opinions of bank management. Accordingly, because each of these criteria is
subject to change, the allocation of the allowance below is made for analytical
purposes and is not necessarily indicative of the trend of future loan losses
in any particular loan category. The total allowance is available to absorb
losses from any segment of the portfolio.
 
The following table presents the allocation of the allowance for loan losses
for each of the last five years.

NONPERFORMING ASSETS
 
The Company discontinues the accrual of interest on loans, excluding credit
card loans, when the continuity of the contractual principal or interest is
deemed doubtful by management or when 90 days past due or more and the loan is
not well secured or in the process of collection. Interest income is recorded
on these loans only as it is collected. Interest payments on nonaccrual loans
which contain unusual risk features or marginal collateral values may be ap-
plied directly to loan principal for accounting purposes. Renegotiated loans
are loans on which interest is being accrued at less than the original contrac-
tual or existing market rate of interest because of the inability of the bor-
rower to service the obligation under the original terms of the agreement.
There are no renegotiated loans.

The Company's ratio of nonperforming assets to total loans outstanding and
other real estate owned of .09% was below the industry peer group ratio of
 .74%/1/.
 
At December 31, 1996, the $1.7 million in nonaccrual loans consisted of one
commercial real estate construction loan. During 1997, the borrower sold the
property and $200,000 was charged off.

</TABLE>
 
1997 Versus 1996
 
Service charges on deposit accounts increased $349,000, primarily due to an in-
crease in business account analysis fees.
 
Investment management and trust department income increased $372,000, primarily
due to an increase in assets under investment management, other new trust busi-
ness and a change to quarterly billing in 1997 from annual billing in 1996. In-
vestment management and trust department discretionary assets under investment
management grew over $43 million to $134 million at December 31, 1997 from $91
million at December 31, 1996.
 
Merchant card processing fees increased $451,000 primarily due to several new
large volume merchants and continued marketing efforts. The number of merchants
represented increased to 170 at year-end 1997 from 138 at year-end 1996. Mer-
chant interchange expense (in the other expense section) rose $386,000 in 1997.
 
The increase in other operating income of $401,000 was principally attributable
to income of $450,000 earned from the revenue sharing agreement on the sold
credit card portfolio and the introduction in July, 1997 of ATM surcharge fees,
offset by a decrease in rental income and investment center fees.
 
1996 Versus 1995
 
Service charges on deposit accounts increased $118,000 primarily due to an in-
crease in business account analysis fees.

Investment management and trust department income increased $61,000, primarily
due to an increase in assets under investment management and other new trust
business. Investment management and trust department discretionary assets under
investment management grew over $23 million to $91 million at December 31, 1996
from $68 million at December 31, 1995.
 
The increase in other operating income of $211,000 was principally attributable
to miscellaneous fees on a variety of retail services.
 
Investment securities gains decreased $113,000 from the $127,000 of securities
gains recognized in 1995 when the Company restructured its held-to-maturity and
available-for-sale portfolios. The portfolios were restructured in 1995 to more
closely mirror each other in both security composition and maturity distribu-
tion. The 1995 securities gains were from the sale of longer maturity securi-
ties in the available-for-sale portfolio.

</TABLE>
 
1997 Versus 1996
 
Other expenses rose $273,000, or 1%, in 1997 over 1996. This modest increase is
primarily due to the disposition of the credit card portfolio, cost savings
initiatives and two offsetting non "core" items.
 
Salaries and employee benefits increased $527,000 as a result of normal raises,
higher compensation due to competitive market conditions, additional upgrades
and increased staff in the growing areas of the bank including indirect auto,
merchant card processing and commercial departments. This increase was offset
by the elimination of salaries due to the sale of the credit card portfolio.
 
Equipment expense decreased $171,000 primarily due to lower depreciation ex-
pense, as certain assets became fully depreciated, and due to the write off of
equipment formerly used to process the credit card portfolio.
 
Data processing fees decreased $324,000 primarily as a result of the disposi-
tion of the credit card portfolio.
 
Other operating expenses decreased $319,000 primarily due to two non "core"
items. First, the Company recognized a pre-tax gain of $515,000 on the sale of
surplus property formerly leased to McDonald's Corporation. Secondly, the Com-
pany made a pre-tax contribution of $300,000 to the newly established Oak Brook
Bank Charitable Foundation. The impetus to organize the Foundation was (1) a
change in the Community Reinvestment Act regulations which provide specific in-
centives for certain charitable gifts, (2) greater leeway in investing the
Foundation funds, and (3) an increase in the Company's marginal tax rate caused
by the credit card sale.
 
1996 Versus 1995
 
Other expenses rose $511,000, or 3%, in 1996 over 1995. Salaries and employee
benefits rose $845,000. The increase is due to additional staffing, normal sal-
ary increases and higher benefit payments.
 
Occupancy expense increased $115,000 over 1995 due to increased real estate
taxes and lower rental income. In August, 1996, the Company took over approxi-
mately 2,000 square feet of space in its Oak Brook headquarters formerly rented
by a third party.
 
Data processing increased $152,000 primarily due to higher credit card process-
ing fees, trust processing fees and miscellaneous processing fees for compli-
ance and student loans.
 
Advertising and business development expenses decreased $189,000 due to a re-
duction in advertising offset by increased business development costs.

FINANCIAL REVIEW
 
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
FDIC premiums decreased $590,000 due to lower quarterly assessments. The FDIC
premium was decreased to $500 per quarter for "well-capitalized" banks in 1996.
 
INCOME TAX EXPENSE
 
Income taxes for 1997 totaled $6,962,000 as compared to $2,429,000 for 1996 and
$1,996,000 in 1995. When measured as a percentage of income before income tax-
es, the Company's effective tax rate was 34% for 1997 compared to 25% in 1996
and 23% in 1995. The increase in the provision for income taxes and the effec-
tive tax rate in 1997 was due to a $3.3 million tax provision on the gain on
the sale of the credit card portfolio. The higher taxable income caused the
Company to be in a marginal 38% tax bracket for pre-tax earnings greater than
$15 million which results in a 35% Federal statutory tax rate (34% in 1996 and
1995) and a certain portion was subject to Illinois state income tax.
 
The increase in the provision for income taxes in 1996 was due to higher pre-
tax earnings while the increase in the effective tax rate was due to a decrease
in tax exempt income as a percentage of pre-tax income.
 
FINANCIAL CONDITION
 
LIQUIDITY
 
Effective management of balance sheet liquidity is necessary to fund growth in
earning assets and to pay liability maturities, depositors' withdrawal require-
ments and shareholders' dividends.
 
The Company has numerous sources of liquidity including a portfolio of shorter-
term assets, readily marketable investment securities, the ability to attract
consumer time deposits and access to various borrowing arrangements.
 
Available borrowing arrangements are summarized as follows:
 
Subsidiary Bank:
 
 . Informal Federal funds lines aggregating $48 million with five correspondent
  banks, subject to continued good financial standing.
 
 . Reverse repurchase agreement lines totaling $100 million with two brokerage
  firms and one correspondent bank, subject to the availability of collateral
  and continued good financial standing.
 
 . Additional advances from the Federal Home Loan Bank of Chicago are available
  based on the pledge of specific collateral and FHLB stock ownership.
 
Parent Company:
 
 . Revolving credit arrangement for $5 million. The line is currently unused and
  matures on May 1, 1998. It is anticipated to be renewed annually.
 
 . The parent company also had cash, short-term investments and other marketable
  securities totaling $7.9 million at December 31, 1997.
 
INTEREST RATE SENSITIVITY
 
Interest rate risk arises when the maturity or repricing of assets differs sig-
nificantly from the maturity or repricing of liabilities. The Company's finan-
cial results could be affected by changes in market interest rates such as the
prime rate, LIBOR and treasury yields as well as competitive pressures for re-
tail deposit products. The objective of interest rate risk management is to
provide the maximum levels of net interest income while maintaining acceptable
levels of interest rate risk and liquidity risk. A number of measures are used
to monitor and manage interest rate risk, including income simulation and in-
terest sensitivity (gap) analyses.
 
An income simulation model is the primary tool used to assess the direction and
magnitude of changes in net interest income resulting from changes in interest
rates. The model incorporates management assumptions regarding the level of in-
terest rate or balance changes on indeterminate maturity deposit products
(passbook savings, money market, NOW and demand deposits) for a given level of
market rate changes. These assumptions are developed through historical analy-
sis. Additionally, changes in prepayment behavior of the mortgage related as-
sets in each rate environment are captured using estimates of prepayment speeds
for the portfolios. Other assumptions in the model include, cash flows and ma-
turities of other financial instruments, changes in market conditions, loan
volumes and pricing, and customer preferences. These assumptions are inherently
uncertain and, as a result, the model cannot precisely estimate net interest
income or precisely predict the impact of higher or lower interest rates on net
interest

income. Actual results will differ from simulated results due to timing, mag-
nitude and frequency of interest rate changes and changes in market conditions
and management strategies, among other factors.
 
The Company's policy objective is to limit the change in annual net interest
income to 10% from an immediate and sustained parallel change in interest
rates of 200 basis points. As of December 31, 1997, the Company had the fol-
lowing estimated net interest income sensitivity profile. The impact of
planned growth and anticipated new business activities is not factored into
the calculation.

INVESTMENT SECURITIES
 
1997
 
The Company's investment portfolio increased $36 million, or 14%, during 1997
to $302 million at year-end from $266 million at year-end 1996. The proceeds
from the sale of the credit card portfolio were reinvested in U.S. Government
agency securities, corporate securities and a time deposit of $10 million with
the buyer. Proceeds from maturing U.S. Treasuries were used to fund continued
loan demand. The Company continued its strategy to shelter current and future
income from state taxation by primarily investing in U.S. Treasury and state
income tax exempt U.S. Government agency securities and to improve the portfo-
lio's overall yield by increasing investment in U.S. Government agency securi-
ties.
 
U.S. Treasury Securities: The Company reduced its holdings of U.S. Treasuries
by $20 million to $71 million at year-end from $91 million at year-end 1996.
Proceeds from maturing U.S. Treasuries were used to fund loan demand. The av-
erage maturity of the U.S. Treasury portfolio was reduced to 1.3 years in 1997
from 1.9 years in 1996.
 
U.S. Government Agency and Mortgage Backed Securities: The U.S. Government
agency securities (including U.S. Government agency mortgage backed securities
and agency collateralized mortgage obligations) portfolio rose $48 million in
1997 to $168 million at year-end from $120 million at year-end 1996. The
growth was mainly from the reinvestment of $40 million of proceeds from the
sale of the credit card portfolio in short to medium term U.S. Government
agency and mortgage-backed securities. To minimize the Company's state tax li-
ability, the majority of U.S. Government securities purchased were exempt from
state income taxes. The average maturity of this sector of the portfolio was
increased to 3.8 years in 1997 from 2.8 years in 1996.

FINANCIAL REVIEW
 
- --------------------------------------------------------------------------------
 
Municipal Securities: The Company's municipal security holdings declined $5
million to $47 million at year-end from $52 million at year-end 1996. Due to
their high yields, low credit risk, and pledgability for public deposits, mu-
nicipal securities remain attractive as investments. All municipal securities
held are rated "A" or better by one or more of the national rating services or
are "non-rated" issues of local communities which, through the bank's own anal-
ysis, are deemed to be of satisfactory quality.
 
Corporate and Other Securities: Holdings of corporate and other securities in-
creased $14 million. The growth was mainly from the reinvestment of $12 million
of proceeds from the sale of the credit card portfolio in a corporate collater-
alized mortgage obligation. The remainder of the portfolio consists primarily
of preferred stocks held by the parent company and Federal Home Loan Bank
stock.
 
1996
 
In 1996, the Company's investment portfolio increased $10 million, or 4%, to
$266 million. The increases were primarily in the U.S. Government agency sector
of the portfolio. The Company continued its strategy to shelter current and fu-
ture income from state taxation by primarily investing in U.S. Treasury and
state income tax exempt U.S. Government agency securities and to improve the
portfolio's overall yield by increasing investment in U.S. Government agency
securities.

/1/Included in U.S. Government agencies are agency mortgage-backed securities
(MBS) and agency collateralized mortgage obligations (CMOs). Given the amortiz-
ing nature of MBS and CMOs, the maturities presented in the table are based on
their estimated average lives at December 31, 1997. The estimated average lives
may differ from actual principal cash flows. Principal cash flows include pre-
payments and scheduled principal amortization.
/2/Yields on state and municipal securities are calculated on a tax-equivalent
basis using a tax rate of 34%.
/3/Included in this amount are corporate CMOs with maturities that are esti-
mated based on the estimated average lives. Also included are preferred stocks
and Federal Home Loan Bank of Chicago stock, which have no maturity date and
are not included in the average months to maturity. Yields on the stocks are
calculated on a tax-equivalent basis using a tax rate of 34% and the 70% divi-
dend received deduction.

LOANS
 
1997
 
At year-end 1997, loans outstanding, net of unearned discount, increased $27.2
million, or 6%, compared to 1996. Indirect auto loans, commercial, home equity
and commercial real estate loans led the 1997 loan growth. Substantially all
of the credit card loans were sold during 1997.
 
Indirect automobile loans increased $47.2 million, or 81%, to $105.8 million
in 1997 primarily due to additional marketing efforts and competitive pricing.
The Company does not buy subprime auto paper.
 
Commercial loans increased $13.8 million and commercial mortgage loans in-
creased $10 million primarily due to competitive pricing strategies and suc-
cessful marketing efforts.
 
Home equity loans increased $10 million, or 18%, to $65.3 million in 1997 pri-
marily due to successful mass marketing efforts.
 
There are no loan concentrations exceeding 10% of total loans at December 31,
1997, which are not otherwise disclosed below. The Company has no foreign
loans; therefore, no loans to Less Developed Countries (LDCs). The Company has
no agricultural loans.
 
1996
 
At year-end 1996, loans outstanding, net of unearned discount, increased $57.4
million, or 16%, compared to 1995. Consumer loans, residential real estate and
commercial real estate loans led the 1996 loan growth. Commercial and credit
card loan growth was constrained as a result of vigorous competition.
 
Indirect automobile loans increased $19 million, or 48%, to $58.6 million in
1996. The Company did not buy subprime auto paper.
 
Residential real estate loans increased $12.5 million, or 15%, due to in-
creased mortgage originations and retaining the majority of these originations
for the Company's loan portfolio.
 
Real estate construction loans increased $7.1 million, or 25%, due to lending
to Chicago area home builders. Commercial mortgage loans increased $8 million,
or 14%, primarily due to interim financing provided for several multi-family
properties.
 
There were no loan concentrations exceeding 10% of total loans at December 31,
1996, which were not otherwise disclosed below. The Company had no foreign
loans; therefore, no loans to Less Developed Countries (LDCs). The Company had
no agricultural loans.

/1/Indirect automobile loans represent consumer auto loans made through a net-
work of new car dealers.
/2/Included in this amount are student loans, direct automobile loans and
check credit loans.
As evidenced by the previous table, loans secured by real estate comprise the
greatest percentage of total loans. Most of the Company's residential real es-
tate loans are secured by first mortgages and the home equity loans are se-
cured primarily by junior liens on one-to-four family residences in the Chi-
cago Metropolitan area. The Company generally limits total advances to a loan
to value ratio of eighty percent or less. Commercial mortgages are generally
secured by properties in the Chicago Metropolitan area.

Variable rate loans are those on which the interest rate can be adjusted for
changes in the Company's index rate (similar to prime rate), The Wall Street
Journal's published prime rate, U.S. Treasury securities, LIBOR or the brokers'
call money rate. Fixed rate loans are those on which the interest rate cannot
be changed during the term of the loan.
 
DEPOSITS
 
1997
 
At year-end 1997, total deposits decreased $20.5 million or 3%. This decrease
was primarily due to a $14 million decrease in savings deposits and NOW ac-
counts and a $13.9 million decrease in time deposits, offset by a $6.3 million
increase in demand deposits. The Company chose to increase its Federal Home
Loan Bank borrowings
rather than run retail time deposit promotions in 1997. At December 31, 1997,
there are no brokered deposits.
 
Average deposits for 1997 increased $26.1 million, or 4%, as compared to 1996.
The increase in average deposits is primarily due to a $14.4 million increase
in noninterest-bearing demand deposits, primarily business accounts, and a
$21.2 million increase in time deposits, primarily from public funds and 1996
retail promotions, offset by a $13.7 million decrease in savings deposits.
 
1996
 
Average deposits for 1996 increased $75.6 million or 14%. The increase in aver-
age deposits is primarily related to a $69.2 million increase in time deposits
and a $17 million increase in non-interest bearing demand deposits, offset by a
$13.3 million decrease in savings deposits and NOW accounts.

BORROWINGS
 
Short-term borrowings, which include Federal funds purchased, securities sold
under agreements to repurchase and treasury, tax and loan demand notes, were
$65.1 million at December 31, 1997 up $9.9 million from $55.2 million at the
end of 1996. The 1997 increase was primarily due to an increase in Federal
funds purchased partially offset by a decline in securities sold under agree-
ments to repurchase. In 1996, short-term borrowings decreased from $60.7 mil-
lion to $55.2 million due to a decrease in securities sold under agreements to
repurchase partially offset by an increase in the treasury, tax and loan
notes.
 
As a member of the Federal Home Loan Bank, the bank may obtain advances se-
cured by certain of its residential mortgage loans and other assets. The Com-
pany significantly expanded its utilization of the Federal Home Loan Bank ad-
vances due to the comparatively favorable terms available. Borrowings in-
creased to $42.5 million at December 31, 1997, while there were no such
borrowings outstanding at December 31, 1996. Borrowings mature from 1998 to
2002 and bear fixed interest rates ranging from 5.48% to 6.41%. See
"Borrowings" note to the financial statements for additional information.
 
CAPITAL RESOURCES
 
One of the Company's primary objectives is to maintain strong capital to war-
rant the confidence of our customers, shareholders and bank regulatory agen-
cies. A strong capital base is needed to take advantage of profitable growth
opportunities that arise and to provide assurance to depositors and creditors.
Banking is inherently a risk-taking activity requiring a sufficient level of
capital to effectively and efficiently manage inherent business risks. The
Company's capital objectives are to:
 
 . maintain sufficient capital to support the risk characteristics of the Com-
  pany and the Company's subsidiary bank; and
 
 . maintain capital ratios which meet and exceed the "well-capitalized" regula-
  tory capital ratio guidelines for the Company and the Company's subsidiary
  bank,
 thereby minimizing regulatory intervention and lowering FDIC assessments.
 
At December 31, 1997, the Company achieved record shareholders' equity of
$71.7 million. The Company's and its subsidiary bank's capital ratios not only
exceeded minimum regulatory guidelines but also the FDIC criteria for "well-
capitalized" banks. See the "Regulatory Capital" note to the financial state-
ments for further discussion.
 
In 1997, cash dividends declared totaled $1,711,000, a 29% increase from 1996.
The Board increased the quarterly cash dividends in January and October based
on strong earnings and capital. In January, 1998, the Board increased its cash
dividend by 20% on both the Class A and common stock. The new quarterly divi-
dend payable in April, 1998 on the Class A common and common stock will be
$.18 per share and $.15 per share, respectively. When annualized, this new
quarterly dividend rate equates to $.72 per share and $.60 per share, on Class
A and common stock respectively. In 1996, cash dividends declared totaled
$1,324,000, a 35% increase from 1995.
 
On January 28, 1997, the Company's Board of Directors authorized a stock re-
purchase program. The program allows the Company to repurchase up to 4%, or
approximately 135,000 shares, of its Class A or common stock through mid-1998.
As of February 15, 1998, a total of 119,496 shares of stock had been repur-
chased at a cost of $2,815,000.
 
On January 27, 1998, the Board of Directors authorized another stock repur-
chase program. The program allows the Company to repurchase up to an addi-
tional 100,000 shares of its Class A common stock over the next 18 months. Re-
purchases can be made in the open market or through negotiated transactions
from time to time depending on market conditions. The stock, if repurchased,
will be held as treasury stock to be used for general corporate purposes.
 
YEAR 2000 COMPLIANCE
 
The Company has developed and is implementing its Year 2000 Project Plan. The
Company is conducting a review and an assessment of its computer systems and
is contacting its software vendors in determining their Year 2000 readiness.
The Company believes that future releases of current software and conversion
to new software will minimize the Year 2000 problem. However, due to possible
interaction with noncompliant third party computer systems, the Company could
encounter unanticipated problems. The financial impact of Year 2000 compliance
is not anticipated to be material to the Company's financial condition. The
Company will continue to expense costs for Year 2000 compliance as they occur
consistent with generally accepted accounting principles.
                                                                             21

NEW ACCOUNTING PRONOUNCEMENTS
 
In June, 1997, the FASB issued Statement 130, "Reporting Comprehensive Income."
Statement 130 established standards for reporting and presentation of compre-
hensive income and its components in a full set of general-purpose financial
statements. Statement 130 is effective for both interim and annual periods be-
ginning after December 15, 1997, and is not expected to have a material impact
on the consolidated financial statements.
 
In June, 1997, the FASB issued Statement 131. "Disclosures about Segments of an
Enterprise and Related Information." Statement 131 established standards for
the way public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises to re-
port selected information about operating segments in interim financial reports
issued to shareholders. Statement 131 is effective for financial periods begin-
ning after December 15, 1997, and is not expected to have a material impact on
the Company.

REPORT OF INDEPENDENT AUDITORS
 
- --------------------------------------------------------------------------------
Board of Directors and Shareholders
First Oak Brook Bancshares, Inc.
 
We have audited the accompanying consolidated balance sheets of First Oak Brook
Bancshares, Inc. and subsidiary as of December 31, 1997 and 1996, and the re-
lated consolidated statements of income, changes in shareholders' equity, and
cash flows for each of the three years in the period ended December 31, 1997.
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 stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of mate-
rial misstatement. An audit includes examining, on a test basis, evidence sup-
porting 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 pre-
sentation. We believe that our audits provide a reasonable basis for our opin-
ion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of First Oak Brook
Bancshares, Inc. and subsidiary at December 31, 1997 and 1996, and the consoli-
dated results of their operations and their cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally ac-
cepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
- -------------------------------------------------------------------------------
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
The consolidated financial statements include the accounts of First Oak Brook
Bancshares, Inc. (the Company) and its wholly-owned subsidiary, Oak Brook
Bank. The accounting and reporting policies of the Company and its subsidiary
conform to generally accepted accounting principles and to general practice
within the banking industry.
 
The Company, through its subsidiary bank, operates in a single segment engag-
ing in the general retail and commercial banking business, primarily in the
Chicago Metropolitan area. The services offered include demand, savings and
time deposits, corporate cash management services, commercial lending products
such as commercial loans, mortgages and letters of credit, and personal lend-
ing products such as residential mortgages, home equity lines and auto loans.
In addition, related products and services are offered including discount bro-
kerage, mutual funds and annuity sales and foreign currency sales. The subsid-
iary bank has a full service investment management and trust department.
 
USE OF ESTIMATES: The preparation of the consolidated financial statements in
conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the amounts reported in the con-
solidated financial statements and accompanying notes. Actual results could
differ from those estimates.
 
INVESTMENT SECURITIES: Securities are classified as held-to-maturity, avail-
able-for-sale or trading at the time of purchase and reevaluated as of each
balance sheet date. Securities are classified as held-to-maturity when the
Company has the positive intent and ability to hold the securities to maturi-
ty. Held-to-maturity securities are stated at amortized cost. Available-for-
sale securities are stated at fair value, with the unrealized gains and loss-
es, net of tax, reported in a separate component of shareholders' equity. The
Company does not carry any securities for trading purposes.
 
The amortized cost of securities classified as held-to-maturity or available-
for-sale is adjusted for amortization of premiums and accretion of discounts
to maturity, or in the case of mortgage-backed securities, over the estimated
life of the security. The cost of securities sold is based on the specific
identification method.
 
LOAN FEES AND RELATED COSTS: Loan origination and commitment fees and certain
direct loan origination costs are deferred and amortized as an adjustment of
the related loan's yield over the contractual life of the loan using the lev-
el-yield method.
 
ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses is comprised of both
general and specific valuation allowances. The Company records specific valua-
tion allowances on commercial, commercial mortgage and construction loans when
a loan is considered to be impaired. A loan is impaired when, based on an
evaluation of current information and events, it is probable that the Company
will not be able to collect all amounts due (principal and interest) pursuant
to the original contractual terms. The Company measures impairment based upon
the present value of expected future cash flows discounted at the loan's orig-
inal effective interest rate or the fair value of the collateral if the loan
is collateral dependent. Interest income on impaired loans is recognized using
either the cash basis method or a cost recovery method depending upon the cir-
cumstances. General valuation allowances are maintained at a level believed
adequate by management to absorb estimated probable loan losses. Management's
periodic evaluation of the adequacy of the allowance is based on the Company's
past loan loss experience, peer loan loss experience, known and inherent risks
in the portfolio, composition of the loan portfolio, current economic condi-
tions, and other relevant factors.
 
Commercial and retail loans are placed on non-accrual status when the
collectibility of the contractual principal or interest is deemed doubtful by
management or becomes 90 days or more past due and the loan is not well se-
cured or in the process of collection.
 
PREMISES AND EQUIPMENT: Premises, leasehold improvements and equipment are
stated at cost less accumulated depreciation and amortization. For financial
reporting purposes, depreciation is charged to expense by the straight-line
method over the estimated useful life of the asset. Leasehold improvements are
amortized over a period not exceeding the term of the lease, including renewal
option periods.
 
INCOME TAXES: The Company and its subsidiary file consolidated income tax re-
turns. The subsidiary provides for income taxes on a separate return basis and
remits to the Company amounts determined to be currently payable. Under this
method, deferred tax assets and liabilities are determined based on differ-
ences between financial reporting and tax bases of assets and liabilities and
are measured using the enacted tax rates and laws that will be in effect when
the differences are expected to reverse.
 
EARNINGS PER SHARE: In February 1997, the Financial Accounting Standards Board
issued Statement of Financial Accounting Standard No. 128, "Earnings per
Share" (Statement 128). Statement 128 replaces the presentation of primary
earnings per share (EPS) with basic EPS and fully diluted EPS with diluted
EPS.
 
Basic EPS is computed by dividing net income by the weighted average number of
common shares outstanding for the period. Diluted EPS is computed by dividing
net income by the weighted average number of common shares and common equiva-
lent shares for the period. EPS

- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
calculations for prior periods have been restated to reflect the adoption of
Statement 128.
 
STOCK OPTIONS: The Company accounts for stock options in accordance with Ac-
counting Principles Board Opinion No. 25, "Accounting for Stock Issued to Em-
ployees" (APB 25). Under APB 25, because the exercise price of the Company's
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recognized. The Company has expanded
its disclosure of stock-based compensation plans and disclosed pro forma data
for new grants of stock-based instruments.
 
CASH AND CASH EQUIVALENTS: For purposes of the Consolidated Statements of Cash
Flows, cash and cash equivalents include cash and due from banks, Federal funds
sold, securities purchased under agreements to resell and interest bearing de-
posits with banks with original maturities of 90 days or less.
 
RESTATEMENT AND RECLASSIFICATION: Certain amounts in the 1996 and 1995 consoli-
dated financial statements have been reclassified to conform to their 1997 pre-
sentation.
 
NOTE 2. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
Statement of Financial Accounting Standards No. 107, "Disclosures about Fair
Value of Financial Instruments," requires the disclosure of the fair value of
certain financial instruments. Fair value of a financial instrument is defined
as the amount at which the instrument could be exchanged in a current transac-
tion between willing parties other than in a forced or liquidation sale. The
following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments:
 
CASH AND CASH EQUIVALENTS: The carrying amounts reported on the balance sheet
for cash and short-term instruments approximate those assets' fair values.
 
INTEREST-BEARING DEPOSITS WITH BANKS: The fair value of interest-bearing depos-
its with banks is estimated using a discounted cash flow calculation that util-
izes interest rates currently being offered for similar maturities.
 
INVESTMENT SECURITIES: Fair values for investment securities are based on
quoted market prices.
 
LOANS: For variable rate loans that reprice frequently and with no significant
change in credit risk, fair values are based on carrying amounts. The fair
value for all other loans is estimated using discounted cash flow analyses,
which use interest rates currently being offered for similar loans of similar
credit quality. The fair value does not include potential premiums available in
a portfolio sale. The carrying amount of accrued interest approximates its fair
value.
 
OFF-BALANCE SHEET INSTRUMENTS: Fair values for the Company's off-balance sheet
instruments (letters of credit and lending commitments) are generally based on
fees currently charged to enter into similar agreements.
 
DEPOSIT LIABILITIES: The fair values for certain deposits (e.g., interest and
noninterest-bearing demand deposits, savings deposits and NOW accounts) are, by
definition, equal to the amount payable on demand. The fair value estimates do
not include the intangible value of the existing customer base. The carrying
amounts for variable rate money market accounts approximate their fair values.
Fair values for time deposits are estimated using a discounted cash flow calcu-
lation that applies interest rates currently being offered on time deposits to
a schedule of aggregated expected monthly maturities.
 
SHORT-TERM DEBT: The carrying amounts of Federal funds purchased, overnight re-
purchase agreements and Treasury, tax and loan demand notes approximate their
fair values. The fair values of term repurchase agreements are estimated using
a discounted cash flow calculation that utilizes interest rates currently being
offered for similar maturities.
 
LONG-TERM DEBT: The fair value of the Federal Home Loan Bank borrowings is es-
timated using a discounted cash flow calculation that utilizes interest rates
currently being offered for similar maturities.
 
The assumptions and estimates used in the fair value determination process are
subjective in nature and involve uncertainties and significant judgment and,
therefore, fair values cannot be determined with precision. Changes in assump-
tions could significantly affect these estimated values.
                                                                              29

</TABLE>
The Company grants real estate, commercial and consumer loans primarily within
the Chicago Metropolitan area. Generally, real estate and consumer loans are
secured by various items of property such as first and second mortgages, auto-
mobiles and cash collateral. The majority of the commercial portfolio is se-
cured by business assets.
 
Loans secured by residential real estate are expected to be paid by the borrow-
ers' cash flows or proceeds from the sale or refinancing of the underlying real
estate. Almost all of these loans are secured by real estate within the Chicago
Metropolitan area. Performance of these loans may be affected by conditions in-
fluencing the local economy and real estate market. However, the Company's loan
policy addresses this issue, as funds loaned for portfolio loans generally may
not exceed eighty percent of the appraised value of the real estate.
 
In the normal course of business, there are various outstanding commitments and
contingent liabilities, including commitments to extend credit, that are not
reflected in the financial statements. The Company's exposure to credit loss in
the event of nonperformance by the other party to the commitments and lines of
credit is limited to their contractual amount. Many commitments to extend
credit expire without being used. Therefore, the amounts stated below do not
necessarily represent future cash commitments. These commitments (including
letters of credit) and credit lines are subject to the same credit policies
followed for loans recorded in the financial statements.

The Company had no impaired loans, as defined, at year-end 1997. At December
31, 1996, the recorded investment in loans considered impaired was $1,730,000.
The allowance for loan losses related to impaired loans was $400,000 at year-
end 1996. The Company did not recognize any interest income associated with
impaired loans during 1997 or 1996. If interest had been accrued at their
original terms, such income would have approximated $52,000 in 1997 and
$101,000 in 1996. The Company had no impaired loans in 1995.
 
The Company's bank subsidiary has granted loans to its officers and directors,
as well as to the officers and directors of the Company and to their associ-
ates. Related-party loans are made on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with unrelated parties and do not involve more than normal risk
of collectibility. The aggregate amount of these loans was $8,145,000 and
$6,571,000 at December 31, 1997 and 1996, respectively. During 1997, new loans
totaled $2,777,000 and repayments totaled $1,203,000.
 
Certain principal shareholders of the Company are also principal shareholders
of Amalgamated Investments Company, parent of Amalgamated Bank of Chicago. The
Company's subsidiary bank periodically enters into loan participations with
Amalgamated Bank of Chicago. At December 31, 1997 and 1996, the Company had
outstanding loan participations sold of $4,231,000 and $1,049,000 respectively
with Amalgamated Bank of Chicago.

NOTE 9. SHAREHOLDERS' EQUITY
 
Each share of Class A common stock is entitled to one-twentieth of one vote and
a cash dividend of at least 120% of the dividend declared on the common stock.
Holders of the Class A common stock, upon liquidation of the Company, are enti-
tled to receive an aggregate amount per share equal to the $6.31 offering price
of the Class A common stock before any amount is paid to holders of the common
stock. The common stock is convertible into Class A common stock on a one-for-
one basis at any time.
 
At December 31, 1997, the Company has reserved for issuance 235,263 shares of
common stock for the Stock Option Plan and 1,884,159 shares of Class A common
stock for conversions of common stock into Class A common stock.
 
Payment of dividends by the Company's subsidiary bank is subject to both Fed-
eral and state banking laws and regulations that limit the amount of dividends
that can be paid by the bank without prior regulatory approval. At December 31,
1997, $18,853,000 of undistributed earnings was available for the payment of
dividends by the subsidiary bank without prior regulatory approval.
 
NOTE 10. REGULATORY CAPITAL
 
The Company and its bank subsidiary are subject to various regulatory capital
requirements administered by the Federal banking agencies. Failure to meet min-
imum capital requirements can initiate certain mandatory, and possibly addi-
tional discretionary actions by regulators that, if undertaken, could have a
direct material effect on the Company's financial statements. Under capital ad-
equacy guidelines and the regulatory framework for prompt corrective action,
the Company and its bank subsidiary must meet specific capital guidelines that
involve quantitative measures of assets, liabilities, and certain off-balance
sheet items as calculated under regulatory accounting practices. Capital
amounts and classification are also subject to qualitative judgments by the
regulators about components, risk weightings, and other factors.
 
Regulations require the Company and its bank subsidiary to maintain minimum
amounts of total and Tier 1 capital, minimum ratios of total and Tier 1 capital
to risk-weighted assets, and a minimum ratio of Tier 1 capital to average as-
sets to ensure capital adequacy. Management believes, as of December 31, 1997,
that the Company and its bank subsidiary meet all capital adequacy requirements
to which they are subject.
 
The Company and its bank subsidiary's actual capital amounts and ratios are
presented in the following table. As of December 31, 1997, the most recent reg-
ulatory notification categorized the bank subsidiary as well capitalized. There
are no conditions or events since that notification that management believes
have changed the institution's category.

Pro forma information regarding net income and earnings per share is required
by Statement No. 123 "Accounting for Stock-Based Compensation" and has been
determined as if the Company had accounted for its employee stock options un-
der the fair value method of that Statement. The fair value for these options
was estimated at the date of grant using a Black-Scholes option pricing model
with the following weighted-average assumptions for 1997, 1996 and 1995, re-
spectively: risk-free interest rates of 5.5%, 6.4% and 5.5%; dividend yields
of 3.3%, 3.1% and 2.4%; volatility factor of the expected market price of the
Company's common stock of .18; and a weighted-average expected life of the op-
tion of 5 years.
 
The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including expected stock price volatility. Be-
cause the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in manage-
ment's opinion, the existing models do not necessarily provide a reliable sin-
gle measure of the fair value of its employee stock options.
 
For the purposes of pro forma disclosures, the estimated fair value of the op-
tions is amortized to expense over the options' vesting period. The Company's
pro forma information follows (dollars in thousands, except for earnings per
share):

NOTE 14. EMPLOYEE BENEFIT PLANS
 
The Company has a 401(k) savings plan that allows eligible employees to defer
a percentage of their salary, not to exceed 10%, which will be matched by the
Company based on a formula tied to Company profits. The maximum Company lia-
bility is 4% of aggregate eligible salaries. For 1997, 1996 and 1995, the
Company's contributions to the plan were $255,000, $246,000, and $205,000, re-
spectively.

age of executive officer's final base salary. For 1997, 1996, and 1995, the
Company's accrued expense for the plan was $154,000, $146,000, and $133,000,
